origin of dorsal. Head small, an angle in outline at occiput, back 

 slightly arched in front of dorsal. Origin of dorsal over interspaces 

 between ventrals and anal, its longest rays nearly equal to base of 

 anal. Pectorals almost reach ventrals. Origin of anal immediately 

 behind dorsal. Caudal forked for nearly f its length, the lower 

 lobe longest. Lateral line distinct, decurved, interrupted on tail. 

 Another lateral furrow or groove extends under the scales from the 

 head to the tail, but has no pores. Sides silvery, no other color- 

 markings.

. Head 6 ; depth 8 ; eye 5. D. 9 ; A. 7 ; V. 6. 



Gill-openings not extending below upper base of pectorals ; rudi- 

 mentary caudal rays greatly developed, extending forward along 

 lower edge of tail half way to tip of anal, the fatty keel extending 

 to under tip of anal, both equally developed on dorsal side. Inner 

 mandibulary barbels attached to base of outer. 



Acanthopsis lachnostoma Rutter, new species. 



Head 4f ; depth 7f ; eye 6 h D. 8 ; A. 6. 



Head and body long and compressed, the back nearly straight, 

 slightly elevated at origin of dorsal. Eyes high and posterior, in- 

 terorbital £ eye, postorbital part of head less than eye. Head regu- 

 larly arched anteriorly, length of snout equal to greatest depth of 

 body ; mouth with ten barbels, four on mandibles, the posterior of 

 which scarcely projecting beyond the membrane which connects 

 them ; nostrils close together in middle of snout, the anterior with a 

 short tube ; suborbital spine in front of eye, hidden in a groove ; 

 entire mouth and gill-cavity thickly covered with elongate papillse ; 

 larger and more scattered in mouth cavity, where some of them are 

 slightly branched, papillse also present on the outer edge of the 

 filamants of the outer gill-arch. Origin of dorsal nearer snout than 

 base caudal, longest ray If in head ; origin of ventrals slightly 

 nearer caudal ; a fold of skin in axil. Pectorals horizontal ; caudal 

 slightly emarginate, li in head. Scales very minute, about 200
