14. Diagnoses of New Species of Marine Fishes from South African 

 Waters. By K. H. BARNARD, M.A., F.L.S., Assistant Director. 



THE following diagnoses of new species of Fishes are the result of an 

 examination of the Collection of Fishes in the South African Museum. 

 When the whole collection has been thoroughly examined there will 

 probably be some more species to be described, but it is thought that 

 these should be published as soon as possible with a view to aiding 

 the work being done on the Fishes of this region by other workers. 



CYCLOSTOMATA. 

 FAMILY MYXINIDAE. 



HEPTATRETUS PROFUNDUS, n. sp. 



Five gill-openings. Teeth, 11 in outer, 10 in inner row, the anterior 

 3 in the outer, the anterior 2 in the inner, row, basally fused. Head 

 (i.e. from nostril to first gill-opening) 4 times, depth of body (at 

 level of gill-openings) 12 times in total length. Ventral fin ending at 

 a great distance (100 mm.) behind last gill-opening. 620 mm. Dark 

 brown. 



Off Cape Point, 400 fathoms, s.s. Pieter Faure. 



The forward position of the gills at once removes any doubt as to 

 this specimen being merely a five-gilled aberration of the Common 

 South African Hag (H. hexatrema). The second gill-pouch on the left 

 side is degenerate, being only about a quarter of the size of the others. 

 This is the first record of a fi ve-gilled Heptatretus and the deep-water 

 habitat is exceptional for a Jiember of this genus. 



HEPTATRETUS OCTATREMA, n. sp. 



Eight gill-openings. Teeth 10 in both rows ; the anterior 3 in the 

 outer, the anterior 2 in the inner, row, basally fused. Head 4 times, 

 depth of body 25 times in total length. Ventral fin ending only a 

 short distance (8-10 mm.) behind last gill-opening. 300 mm. 

 Brownish.
