- Description: Grenadier fishes of the families Bathygadidae and Macrouridae from southern Africa are reviewed since publication of the book Smiths’ Sea Fishes (1986). The bathygadid and macrourid fauna is increased to 46 species in 20 genera with the addition of the following new species and new records for southern Africa: Bathygadus cottoides, Caelorinchus kaiyomaru, Caelorinchus karrerrae, Caelorinchus simorhynchus sp.n, (misidentified in southern Africa as Caelorinchus fasciatus), Caelorinchus trunovi sp.n, (misidentified in southern Africa as Caelorinchus flabellispinis), Cetonurus globiceps, Co- ryphaenoides carapinus, Coryphaenoides grahami, Coryphaenoides mcmillani, Haplomacrurus nudirostris, Hymenocephalus heterolepis (uncertain identification), Malacocephalus occidentalis, Nezumia spinosa, Nezumia umbracincta sp.n., Odon- tomacrurus murrayi, Sphagemacrurus richardi, Ventrifossa mystax sp.n, (previously identified as V. sp. aff. divergens), and an indeterminate species of Ventrifossa. Name changes include: formerly Nezumia hebetata in southern Africa changed to Kumba sp.; formerly Nezumia bubonis and N. leonis now included in Kuronezumia; formerly Ventrifossa ori now Lucigadus ori; Paracetonurus sp. now Pseudonezumia sp. The species of Macrourus from southern Africa is identified as M. carinatus (Gunther, 1878). Range extensions of previously known grenadiers include Caelorinchus acanthiger far into the western Indian Ocean and Australia, C. denticulatus to Kenya, Nezumia milleri to southern Namibia, N. propinqua to Natal, Trachonurus villosus to off False Bay, western Cape Province, Ventrifossa mystax, sp. n. to the Cape west coast and V. nasuta to off Port Elizabeth. , 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: An advanced diplacanthid (Climatiiformes) is described from a Famennian estuarine environment of South Africa. It is characterized by having exceptionally long thin fin spines and a deep body form. Unusual details of the fins and fin spine insertions are preserved. This is the first record of a diplacanthid from the Southern Hemisphere.
