New Species of Marine Fishes from South African Waters. 441 



interorbital width, 3f in length of head, 10|-11 in length of body. 

 Eye touching dorsal profile, interorbital space flat or slightly concave. 

 Maxilla posteriorly enlarged, extending to vertical from centre of eye. 

 Opercular flaps voluminous, overlapping. D 16-17, A 16-17. 

 Dorsal commencing opposite vent, slightly in advance of anal, which 

 commences behind middle of body. P 10. Caudal peduncle 2f 

 times its greatest depth. Scales : 1. 1. 53-55 ; 1. tr. 13-14. Gill- 

 rakers 14 on lower part of anterior arch. Pyloric caeca (14-) 15. Up 

 to 325 mm. Deep violet black on head, lighter on body. 



Off Cape Point, 630 fathoms, s.s. Pieter Faure. 



This species is closely allied to blandfordi Alck. (1892) from the 

 Arabian Sea, but differs in the slightly larger eye, the maxilla extending 

 farther back, the fewer scales, and the more slender caudal peduncle. 

 Described from two specimens, 325 and 280 mm. long, and from three 

 somewhat mutilated young specimens. 



APODES. 

 FAMILY SYNAPHOBRANCHIDAE. 



DlASTOBRANCHUS, n. g. 



Dorsal commencing behind vent, which is less than a head's length 

 distant from gill-slits. Pectoral considerably longer than snout. 

 Gill-slits ventro-lateral, oblique, separated. Tail more than 3 times 

 length of body to vent. Scales extending over head and cheeks. 

 The patch of teeth on front of vomer distinctly separated by a gap 

 from the single series on the hinder part, the first two teeth of which 

 are conical and larger than any of the other teeth in the mouth. 



Except for the separate gill-slits, the species for which this new genus 

 is proposed, might well go into Synaphobranchus, as the forward 

 position of the vent is not by itself of sufficient importance to be 

 considered a generic character. In the short extension of the cleft 

 of the mouth behind the eye it resembles Ilyophis. 



DlASTOBRANCHUS CAPENSIS, n. Sp. 



Depth of body 3 (adult)-4 (juv.), length of head (to pectoral) l-lf 

 in length of body (to vent). Length of body 4|-5 in total length. 

 Eye 2-2J in snout, 1-1J in interorbital width, 6-7 in length of head. 

 Mouth not more than twice length of snout, extending not more than 

 an eye's length behind posterior margin of eye, 1| in length of head.
