- Description: Deep-sea anglerfishes (Lophiiformes, Ceratioidei) of the familes Caulophrynidae, Melanocetidae, Himantolophidae, Diceratiidae, Oneirodidae, Thaumatichthyidae, Centrophrynidae, Ceratiidae, Gigantactinidae and Linophrynidae from southern Africa are reviewed since the publication of the book Smiths’ Sea Fishes (1986, 1991). Twenty-three new records of ceratioid anglerfishes are reported for the region, bringing the total to 32. No new taxa are described. The faunal area for southern African deep-sea fishes is expanded from that of Smiths’ Sea Fishes in order to include several literature records and recognize the broad distributions of these fishes through the deep-pelagic Atlantic/Indo-Pacific transit zone. Keys to all families, genera and species, as well as descriptions of all southern African specimens, are provided. The bulk of this material was collected during research cruises of South Africa’s RS AFRICANA and MEIRING NAUDE. , Rhodes University Libraries (Digitisation)

- Description: Part 1: We report here information on the occurrence of the deep demersal fish species known to date from the Maldivian Exclusive Economic Zone below a depth of 180 m. Collections of Maldivian deep demersal fishes are held by The Natural History Museum, London (BMNH); the Bernice P. Bishop Museum, Honolulu; the Field Museum of Natural History, Chicago; the Marine Research Section, Ministry of Fisheries and Agriculture, Male, Republic of Maldives; the South African Museum, Cape Town; and the Zoological Survey of India, at the Indian Museum, Calcutta. Specimens from all of these institutions have been studied by the authors. In addition, the authors carried out sampling of the slope shark fishery during March - April 1996, which resulted in a significant new collection of shark material. A total of 99 deep demersal species are reported here which includes 36 new records for the Maldives. The six most speciose families are the Macrouridae (7 species), Congridae (5), Lutjanidae (5), Squalidae (4), Ogocephalidae (4) and Halosauridae (4). , Part 2: Seventy-eight fish species are recorded from the Maldives for the first time. A further 30, which have been recorded in the literature but not included in previous reviews of Maldivian fishes, are listed. The total known shore and epipelagic fish fauna of the Maldives now stands at 1007 species. The total known demersal and epipelagic fish fauna is raised to 1090. , Rhodes University Libraries (Digitisation)

Systematics and Osteology of the Zoarcidae (Teleostei: Perciformes)

- Description: The eelpouts, Zoarcidae, are a group of perciform fishes, most species of which inhabit continental shelves and slopes of boreal seas. There are about 220 valid species of eelpouts; most are rare, deep-sea forms and the systematics and biology of the group has been neglected by most workers. This work is a contribution to the improvement of that state. The anatomy of the Zoarcidae was studied in an attempt to reconstruct phylogeny and establish generic limits. From an analysis of a matrix of 76 characters, the 45 genera recognised here form 4 subfamilies. The Lycozoarcinae contains only the primitive Lycozoarces hubbsi. The others, Zoarcinae, Gymnelinae, and Lycodinae, for the most part, include genera recognised in previous classifications (Gill, 1862, 1864; Andriashev, 1939). The more primitive zoarcids are characterised by having 4-6 suborbital bones arranged in a circular pattern close to the orbit, and “complete” cephalic lateralis pore patterns, except some of the few deep-sea forms. The more derived zoarcids are characterized by having 6-11 suborbital bones arranged in an angled, or “L”-shaped" pattern away from the orbit (except a few which have lost some bones) and the loss of the interorbital pores (except for some reversals in Lycenchelys and Lycodapus). Zoarcids are considered to have originated in the North Pacific Ocean, perhaps as early as the Eocene, when a pre-percoid radiation occurred. The suborder Zoarcoidei (today some 8-9 families) spread across the Pacific rim. Among Zoarcidae, a pre-Miocene radiation took place along the western coasts of the Americas, with areas of endemism forming in the Magellan Province of South America and Antarctica. Subsequent spreading back into northern waters occurred in Melanostigma and Pachycara. , Rhodes University Libraries (Digitisation)

- Description: A historical resume of fish collecting in the Maldive Islands is presented, beginning with the collection o f J. Stanley Gardiner in 1899-1900. Specimens of Maldives fishes have been examined at the Marine Research Section of the Ministry of Fisheries and Agriculture, Republic of Maldives and the five museums which house most of the fishes that have been collected in the islands: the Natural History Museum, London; Bernice P. Bishop Museum, Honolulu; California Academy of Sciences, San Francisco; Field Museum of Natural History, Chicago; and the Senckenberg Museum, Frankfurt. A total of 899 species of epipelagic and shore fishes are recorded from the Maldives; 201 of these are new records for the islands. Thirty-two of the 899 are recorded by generic name only. Some of these could not be identified to species due to poor condition or to their being juveniles, but most appear to be undescribed. , Rhodes University Libraries (Digitisation)

- Description: The liparidid fishes collected in the Southern Ocean by the U.S. Navy vessel “Eltanin” were reviewed in an unpublished M.Sc. thesis by the junior author (Tompkins, 1977). These collections include several hundred specimens, of which 134, representing at least 10 species of the genus Paraliparis, have been re-examined by the senior author and are the subject of the present paper. Descriptions are given for five new species of Antarctic Paraliparis: P. anarthractae, P. andriashevi, P. eltanini, P. incognita, and P. fuscolingua. Four of the new species are illustrated; the fifth (P. incognita) was illustrated by Andriashev (1986: Fig. 59) as P. terraenovae Regan, 1916. P. edentatus Andriashev, 1986 is synonymized with P. terraenovae, and additional data on this species are presented. A probable new species of Paraliparis is diagnosed but not named due to the poor condition of the single specimen. New records of five other rare species (P. antarcticus Regan P. devriesi Andriashev, P. meganchus Andriashev, P. stehmanni Andriashev, and P. tetrapteryx Andriashev) are discussed. , Rhodes University Libraries (Digitisation)

- Description: Various and disparate opinions have been expressed with regard to the phylogenetic affinities of Pseudocrenilabrus, a seemingly generalized and primitive haplochromine genus. These views are reconsidered and rejected. Instead, it is suggested that Pseudocrenilabrus is a derived and paedomorphic taxon evolved from a generalized haplochromine ancestor such as would be represented amongst extant African cichlids by a species of the genus Astatotilapia; for the moment it is not possible to identify a sister group more precisely. The suggestion that Pseudocrenilabrus is a paedomorphic taxon is based on certain Osteological and dental features, particularly the reductional trend manifest in the infraorbital bones of its three constituent species. A new diagnosis and synonomy are provided for the genus, together with notes on its anatomy, osteology and meristic features. , Rhodes University Libraries (Digitisation)

- Description: Two genera of Squirrelfishes of the subfamily Holocentrinae are found in the Indo-Pacific region: Neoniphon (Flammeo of recent authors) and Sargocentron (Adioryx of most recent authors). A total of 19 species of these two genera occur in the Indian Ocean west of the southern tip of India: Neoniphon argenteus, N. aurolineatus (Flammeo scythrops Jordan & Evermann and Holocentrus anjouanae Fourmanoir are junior synonyms), N. opercularis, N. aurolineatus, Sargocentron caudimaculatum, S. diadema, S. ittodai (first records for the Red Sea and western Indian Ocean), S. macrosquamis (recently described from the Red Sea and Amirante Group, Seychelles, the range here extended to Kenya, Mozambique, Mauritius, and the Chagos Archipelago), S. melanospilos (usually misidentified as cornutum which is known only from the Indo-Malayan region), S. microstoma (known in the region only from Maldive Islands and Astove Island), S. praslin (usually not distinguished by authors from S. rubrum; Holocentrum marginatum Cuvier is a synonym), S. punctatissimum (has priority over lacteoguttatum due to selection by first revisor, Bleeker, 1873), S. rubrum, S. seychellense (an insular western Indian Ocean species), S. spiniferum (Holocentrum melanotopte- rus Bleeker is a junior synonym), S. tiere (Holocentrum elongatum Steindachner is a junior synonym), S. tiereoides (a new western Indian Ocean record), S. violaceum, and a new species, S. inaequalis (closely allied to macrosquamis Go- lani, 1984, differing in variable Spination of preopercle, modally one fewer pectoral ray, fewer average number of lateral-line scales and a more elongate body). S. inaequalis is described from a total of 7 specimens from the Chagos Archipelago, Seychelles and Comoro Islands. S. melanospilos is recorded for the first time from the Red Sea where it appears to be subspecifically distinct from populations elsewhere in the Indo-Pacific region (no subspecific name proposed). Holocentrum macropus Gunther, allegedly collected at Mauritius, is a misidentification of the Atlantic Holocentrus ascensionis (Osbeck). A lectotype is selected for S. microstoma. Neotypes are designated for S. praslin and S. rubrum. Colour photographs of fresh specimens of all of the species except S. macrosquamis are presented. , Rhodes University Libraries (Digitisation)

A total of 19 species of these two genera occur in the Indian Ocean west of the southern tip of India: Neoniphon argenteus, N. aurolineatus (Flammeo scythrops Jordan & Evermann and Holocentrus anjouanae Fourmanoir are junior synonyms), N. opercularis, N. aurolineatus, Sargocentron caudimaculatum, S. diadema, S. ittodai (first records for the Red Sea and western Indian Ocean), S. macrosquamis (recently described from the Red Sea and Amirante Group, Seychelles, the range here extended to Kenya, Mozambique, Mauritius, and the Chagos Archipelago), S. melanospilos (usually misidentified as cornutum which is known only from the Indo-Malayan region), S. microstoma (known in the region only from Maldive Islands and Astove Island), S. praslin (usually not distinguished by authors from S. rubrum; Holocentrum marginatum Cuvier is a synonym), S. punctatissimum (has priority over lacteoguttatum due to selection by first revisor, Bleeker, 1873), S. rubrum, S. seychellense (an insular western Indian Ocean species), S. spiniferum (Holocentrum melanotopte- rus Bleeker is a junior synonym), S. tiere (Holocentrum elongatum Steindachner is a junior synonym), S. tiereoides (a new western Indian Ocean record), S. violaceum, and a new species, S. inaequalis (closely allied to macrosquamis Go- lani, 1984, differing in variable Spination of preopercle, modally one fewer pectoral ray, fewer average number of lateral-line scales and a more elongate body). S. inaequalis is described from a total of 7 specimens from the Chagos Archipelago, Seychelles and Comoro Islands. S. melanospilos is recorded for the first time from the Red Sea where it appears to be subspecifically distinct from populations elsewhere in the Indo-Pacific region (no subspecific name proposed). Holocentrum macropus Gunther, allegedly collected at Mauritius, is a misidentification of the Atlantic Holocentrus ascensionis (Osbeck). A lectotype is selected for S. microstoma. Neotypes are designated for S. praslin and S. rubrum. Colour photographs of fresh specimens of all of the species except S. macrosquamis are presented. , Rhodes University Libraries (Digitisation)

These three species occur sympatrically at Monkey Bay. Morphological differences between the three species are slight and of little diagnostic value. Live coloration is the most important taxonomic character and can be used reliably to identify adults of the three species. Field observations of live fishes are shown to be of paramount importance in taxonomic studies of the genus Petrotilapia. , Rhodes University Libraries (Digitisation)

Ichthyological Bulletin of the J.L.B. Smith Institute of Ichthyology, No. 44, 27 pages, 17 figures. Doryrhamphus, a genus of trunk-pouch pipefishes commonly associated with rock or coral habitats, is diagnosed and a key is provided to the five species and five subspecies recognized. The genus Dentirostrum Herald and Randall is synonymized with Doryrhamphus, treated species and subspecies are diagnosed and illustrated, distribution (based on material examined) is delineated and comprehensive synonymies are provided. The genus includes two species groups which, (in subadults and adults) differ in having either one or two spines on principal ridges of the posterior predorsal rings. Species of the single-spine group are distinguished by differences in meristic values and preserved coloration, as well as by the presence of one or two ventrolateral projections on the snout of males, or the absence thereof. Species of the two-spine group are distinguished by differences in meristic values and preserved coloration, as well as by the presence of either one or two spines on principal ridges of tail rings. The single-spine group includes the type-species, D. excisus (three subspecies), with one ventrolateral projection on snout in males, A japonicus with no projection on snout, and D. bicarinatus n. sp. with two projections on snout. Doryrhamphus e. excisus (a senior synonym of D. melanopleura), with modally 17-18 trunk rings ranges from eastern Africa and Persian Gulf to the west coast of the Americas. This pipefish, the most widely distributed syngnathid, exhibits some west-east clinal increase in counts of total rings and dorsal-fin rays. Doryrhamphus e. abbreviatus n. ssp. is a Red Sea endemic characterized by modally 16 trunk rings as well as by 26-28 total rings and 18-20 dorsal-fin rays. D. e. paulus (Revillagegido Is., Mexico) shares the modal count of 16 trunk rings, but has 30-32 total rings and 23-27 dorsal-fin rays. D. japonicus (19-20 trunk rings) is known only from the main islands of Japan, whereas D. bicarinatus (16 trunk rings) is known from Indian Ocean coasts of South Africa and Mozambique. The two-spine group includes D. negrosensis (2 subspecies) with 2 spines on ridges of tail rings in subadults and adults and A janssi (one spine on ridges of tail rings. A n. negrosensis (modally 15 trunk and 29 total rings) is known from Borneo to the Ryukyu Is. and southeastward to the New Hebrides, excluding Australia. D. n. malus (modally, 16 trunk and 31 total rings) is an Australian Great Barrier Reef endemic. D. janssi, with more tail rings than D. negrosensis (21-23 versus 13-16), is known from the eastern Indian Ocean (off NW Australia) and from the Gulf of Thailand and Philippines southeastward to New Guinea and NE Australia in the western Pacific Ocean. Planktonic young of A excisus and early juveniles of D. negrosensis are illustrated and briefly described. , Rhodes University Libraries (Digitisation)

- Description: A new species of stingray, Hexatrygon bickelli Heemstra and Smith, is described from a specimen washed up on a beach at Port Elizabeth on the south coast of South Africa. This new species differs from all other batoid fishes in having six gill arches and a peculiar hypertrophied snout that appears to be a well-developed electroreceptive organ, and in the configuration of its spiracles. Other characters that separate H. bickelli from previously known rays (myliobatiforms) are its small simple brain (other rays have a very large complex brain) and the absence of supraorbital crests on the cranium. In addition, all myliobatiforms are neritic (with none having been recorded below 200 m), and H. bickelli is.presumed to live in moderately deep water (400 to 1000 m). The classification of batoid fishes is reviewed, and Hexatrygon is placed in a new family and suborder of the Myliobatiformes. , Rhodes University Libraries (Digitisation)

- Description: A new species of stingray, Hexatrygon bickelli Heemstra and Smith, is described from a specimen washed up on a beach at Port Elizabeth on the south coast of South Africa. This new species differs from all other batoid fishes in having six gill arches and a peculiar hypertrophied snout that appears to be a well-developed electroreceptive organ, and in the configuration of its spiracles. Other characters that separate H. bickelli from previously known rays (myliobatiforms) are its small simple brain (other rays have a very large complex brain) and the absence of supraorbital crests on the cranium. In addition, all myliobatiforms are neritic (with none having been recorded below 200 m), and H. bickelli is.presumed to live in moderately deep water (400 to 1000 m). The classification of batoid fishes is reviewed, and Hexatrygon is placed in a new family and suborder of the Myliobatiformes. , Rhodes University Libraries (Digitisation)
