 D. 11. A. 11. Vert. 63. Oaec. pyl. 26. 



Scales minute. Head and body rather compressed ; the height of 

 the head equals the length of the head, and is two-ninths of tne total 

 (without caudal) ; the length of the heaa is one-half of the distance 

 between the snout and the vertical from the origin of the dorsal fin. 

 Snout very obtuse, scarcely longer than the diameter of the eye, which 

 is three-fourths of the width of the interorbital space. The lower 

 jaw is a little shorter than the upper ; maxillary of moderate width, 

 scarcely reaching to the vertical from the hind margin of the orbit. 

 Teeth of moderate strength ; those along the median line of the hyoid 

 are very small. Prseoperculum with a very distinct lower limb. 

 Fins rather small : the length of the pectoral is less than that of the 

 head, without snout, or than one-half of the distance of its root from 

 the ventrals ; caudal fin slightly emarginate. Back ana sides reddish 

 olive ; sides with numerous, round, light-coloured spots. BeUy whi- 

 tish, powdered with reddish olive ; paired fins and anal colourless ; 

 caudal immaculate. Pyloric appendages very long and wide.

 servation ; no distinctive characters are pointed out : the length of 

 the head is two-sevenths of the total (without caudal) ; maxillary 

 extending to behind the orbit ; origin of the dorsal somewhat nearer 

 to the snout than to the root of the caudal. Eye one-fifth of the
