Description. — Fusiform, slender j snout long-, semielliptically rounded; nape 

 of nostril long- and slender; teeth, about 19 on each side above and below ; central 

 cusp of teeth narrow, pointed, very obliquely inclined, with four to six serratures 

 on posterior base ; middle tooth straig'ht, with one small cusp on each side of base. 

 Small specimens have upper teeth less acute, and no serratures on the lower teeth. 

 Second dorsal less than half the size of the first, commencing* about one-third of 

 the length of its base in front of front edg-e of anal ; anterior edge of anal nearer to 

 the anterior edge of caudal lobe than to posterior edge of base of ventral ; pectorals 

 broad, nearly rectangular at base, narrow towards tip ; anterior edge of base 

 vertically under posterior edge of penultimate gill-opening. Scales very minute, 

 20 in 3 lines about middle of body. Fold at angle of mouth continued above to 

 under middle of eye; a fold on upper eyelid. Color: Back and upper half of side 

 slate color ; fins darker; lower side of snout, body, and tail white ; iris yellow.
