- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 38 , Recent collecting in the Malawi lakes Chilwa and Chiuta has revealed a new haplochromine cichlid fish, Astatotilapia tweddlei, which is described and illustrated. It is distinguished from most members of this genus by an elongate, rounded caudal fin. Although having a distinctly different colour pattern and more slender pharyngeal bone, it shows a greater similarity to A. paludinosa, known only from the Malagarasi Swamp 1200 km to the north in the Zaire ichthyofaunal province, than it does to members of this genus from the closely adjacent Zambezi province from which this wetland system, in the East Coast province is separated by only some 50 km.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 50 , The eelpout fauna of the southwestern Pacific presently includes 6 species, one of which, Pachycara garricki, is described as new. Full species accounts and illustrations are also provided for Melanostigma inexpectatum, Ophthalmolycus campbellensis, and Lycenchelys maoriorum, known previously only from the meager type series. Two species, Melanostigma gelatinosum, and M. vitiazi were redescribed in the first part of this series, but expanded diagnoses are provided here. Lycenchelys maoriomm and O. campbellensis are expected to be endemic to the New Zealand Plateau and perhaps Lord Howe Rise.

Apogon nigripinnis differs from A. niger in having a large ocellus between the lateral line and the pectoral fin. A lectotype for A. niger is designated. A. pharaonis differs from both these species in having shorter pelvic fins, 16-21 instead of 15-18 gill-rakers, and 3 dark bars on the body. Apogon sialis (Jordan & Thompson, 1914), type locality Japan, is the senior synonym of Amia cathetogramma Tanaka, 1917, also described from Japan. Apogon pseudotaeniatus Gon, 1986 from the Red Sea, previously misidentifiedas A.bifasciatus Rüppell, is very similar in colour pattern to A. sialis; it differs in having a larger caudal spot, a dark instead of pale intestine, and in several morphometric characters.

These new records are based mostly on specimens recently collected by the R/V Fridtjof Nansen off Kenya (including new western Indian Ocean records of Halimochirurgus alcocki and of Bathyphylax bombifrons), as well as on some older materials from the J.L.B. Smith Institute of Ichthyology and the South African Museum. Eight species of triacanthodids known from off east Africa are discussed briefly, with special attention given to Bathyphylax bombifrons and B. omen, previously known only from holotypes, for which additional specimens are now available. Seven species are illustrated with photographs.

P. striatus is shown to be the young of P. maculosus (Forsskål, 1775) which is not known from South Africa; it occurs in the Red Sea, Persian Gulf, and along the East African coast to at least 13°S. Holacanthus coeruleus Cuvier, described from a juvenile specimen from the Red Sea, is a junior synonym of Pomacanthus asfur (Forsskål), not P. semicirculatus (Cuvier), thus casting doubt on the record of the letter from the Red Sea.

Smith Institute of Ichthyology; No. 29 , Clinus spatulatus sp. n. is described from 50 specimens collected from an estuary in the southwestern Cape Province, South Africa. The presence of supraorbital tentacles or papillae distinguishes Clinus and Gynutoclinus from other South African genera of the subtribe Clinidi. The new species has simple supraorbital tentacles, an intermediate condition between the well-developed, at least bifid tentacles of Clinus and the simple supraorbital papillae of Gynutoclinus. For this reason Penrith's (1969) diagnosis of Clinus is modified to include the new species as well as the monospecific Gynutoclinus thereby incorporating all South African species with supraorbital papillae or tentacles.

Dasyatis kuhlii is reported from southern Africa based on three specimens from Natal. Records of H. fava, H. imbricata and H. jenkinsii from southern Africa appear to be erroneous, the latter two being misidentifications of H. gerrardi, and the first a misidentified specimen of H. uarnak. Records of H. purpurea are apparently based on Dasyatis violacea and Himantura sp. (possibly H. fai). A key to the 13 species of dasyatids known from southern Africa is presented.

This is the first record of a member of the subfamily Hemerocoetinae from the western Indian Ocean. The two new species belong to the lineage of closely related genera Acanthaphrites Gunther, Pteropsaron Jordan and Snyder, Osopsaron Jordan and Starks, Spinapsaron Okamura and Kishida, and Branchiopsaron McKay. A specimen of Squamicreedia obtusa Rendahl, previously known only from the damaged holotype, is described from Western Australia. It is postulated that the genera Squamicreedia Rendahl, Enigmapercis Whitley (whose range is extended to Western Australia), and Matsubaraea Taki form a closely related group in Hemerocoetinae.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 24 , Electrofishing surveys throughout Malawi have increased the number of mormyrid species known to occur in the country, expanded known ranges of the species and cast doubts on some earlier records. The distribution of each of the eight recorded species is given, and a key is provided for the identification of the species. The available evidence suggests that Gnathonemus nyasensis Worthington, 1933 is a junior synonym of Marcusenius livingstonii (Boulenger, 1898) a species described from the Ruvuma River of Tanzania. Geological evidence supports fish distribution evidence that indicates links between Lake Malawi and East Coast Rivers. Some affinities are also noted between Lake Malawi and Upper Zambezi/Zaire faunas.

This wide-ranging species has been taken in shorefish collections from southern Japan to American Samoa, Australia, Mauritius, Comoro Islands and Gulf of Aqaba. It is distinguished from known congeners by the following combination of characters: presence of a broad interopercular flap; lateral-line scales 32- 39 (mean 35.7), anterior 2-4 scales bearing a spine; anal-fin rays usually 11; total gill rakers on first arch 6-9; interobital width 0.5-1.9 % SL; no ocular flaps; iris lappet bilobed; two small blackish spots near margin of first dorsal fin; and pelvic fin with a large black spot on upper surface near base and usually one or two small black spots or bands distally.

Plotosus nkunga differs most notably in having fewer total gill rakers on the anterior faces of the first two arches, 16 to 21 versus 20 to 25 first arch, 16 to 24 versus 23 to 27 second arch; in having modally one more precaudal vertebra and slight modal differences in number of ribs and branchiostegal rays; in the shapes of the mesethmoid and the parapophyses of the fourth and fifth centra of the anterior complex vertebra; in the length of the maxilla; and in certain body proportions. Descriptions, annotated synonymies and illustrations are given for both species. A key to the five known species of Plotosus is presented.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 59 , Six species of the genus Chascanopsetta are currently recognized. Recent work on otolith morphology from specimens identified as C. lugubris raised the possibility that three forms of C. lugubris are found in the western Indian Ocean. Re-examination of the voucher specimens showed that one of these forms is a new species, C. kenyaensis, from Kenya and Somalia. The other two forms may show differences in otolith morphology due to ontogeny. The new species most closely resembles C. prorigera from the Hawaiian Archipelago, Emperor Seamounts, and the western North Atlantic. These two species differ in lateral-line scale counts, body depth, upper-jaw length, and coloration. Many comparative specimens of C. lugubris were examined. It was found that this species’ distribution rounds the Cape of Good Hope from the southwestern Indian Ocean into the southeastern Atlantic. Specimens from this southern African region show higher dorsal- and anal-fin ray counts than those from more northern areas in the Atlantic, western Pacific, and Indian oceans. There is some indication that what some authors refer to as the Indo-West Pacific subspecies C. lugubris lugubris rounds the Cape of Good Hope and also occurs in parts of the eastern Atlantic. A more thorough comparison of C. lugubris from different regions is needed.
