New Species of Marine Fishes from South African Waters. 443 



diameter of eye. cleft of mouth extending to below anterior third of 

 eye. Vomerine teeth extending back to tip of tongue, i.e. not as far 

 as front margin of eye ; about 3 series in each band, more numerous 

 in front, some of the vomerine teeth subtubercular. Length of gill- 

 slit half the interspace. Vertebrae about 136. Up to 375 mm. 

 Brownish, the vertical fins with dark edging. 



Coast of S.W. Africa, off Cape Peninsula, False Bay, Tristan 

 d'Acunha, 2-60 fathoms. 



This species resembles mystax in the longer tail proportionately to 

 the head and trunk, and in the projecting snout and thick lips ; but 

 it has the vertical fins with black edging as in balearica, and is inter- 

 mediate between the two northern species in the number of vertebrae. 



As is evident from a series of Leptocephali in the South African 

 Museum, this is the adult of the form described by Kaup as Lepto- 

 cephalus capensis. 



FAMILY DYSOMMLDAE. 



DYSOMMA ANGUILLARIS, n. sp. 



Length of body to vent 5 times in length of tail. Length of head (to 

 gill-slit) 7 in total length. Head flat above. Eye 4 in snout, 3| in 

 interorbital space. Snout overlapping lower jaw, 4| in length of 

 head. Lips thick and fleshy. Cleft of mouth extending 2 eye 

 diameters behind eye. Posterior nostril almost as large as eye. 

 Pectoral about 4| in length of head. Dorsal commencing above or 

 slightly in advance of gill-slits, which are subequal to the interspace 

 between them. Distance of vent from posterior end of gill-slit equal 

 to length of one gill-slit. A narrow band of villiform teeth on 

 posterior f of maxilla ; 2 conical teeth, set transversely in front of 

 upper jaw, followed by 4 canine teeth on vomer, the third being the 

 largest ; 7-8 canine teeth on each mandible, set well apart, but not so 

 large as those on vomer ; each of the canine teeth is set in an oval, 

 conical, fleshy papilla with only its point projecting. Snout and 

 lower jaw thickly covered with minute villiform papillae. 360 mm. 

 Silvery- white, base of vertical fins posteriorly dark, but the edges white. 



Off Tugela River mouth, Natal, 63 fathoms, s.s. Pieter Faure. 



The elongate form at once distinguishes this species from the only 

 other known species of the genus : bucephalus, Alck. 1889. The 

 body cavity extends to within 70 mm. of the end of the tail, but the 

 intestinal loop only extends to about the middle of the total length 

 of the body. The stomach contained portions of Crabs,
