23. L. subinornatus n. sp. 



PL IV. f. 1 and 2. 



The body is strongly compressed, fairly elongate 

 and low; its greatest height, contained about eight 

 times in its length, is situated approximately in the 

 middle, whence the height diminishes gradually and 

 uniformly towards head and tail. 



The head is of moderate" size; its length is some- 

 what less than the greatest height of the body. 

 Its upper profile is convex towards the rear, slightly 

 concave towards the fore; this causes the snout to 

 appear considerably depressed. The snout is pointed. 

 From its extremity to the anterior margin of the eye 

 the distance is not quite double the eye's diameter. . 

 The eye has an almost circular contour; its upper 

 margin does not reach up to the upper profile of the 

 head. The posterior nostril is immediately in front 

 of the eye's anterior margin above the middle of it; 

 the anterior nostril is about equally distant from the 

 posterior as from the extremity of the snout. The 

 cleft of the mouth tends upwards obliquely and 

 reaches back almost to the hind margin of the eye. 

 The lower jaw does not project quite so far as the 

 upper ; it has an almost straight under profile, the pro- 

 minent angle is almost wholly wanting. Teeth are 

 present in both jaws. 



Pectoral fins none. The vertical fins are very 

 slightly developed; the dorsal fin has its origin just 

 in front of the vent ; the caudal fin is rounded. 



The vent lies behind the middle of the body;
