The height of the body is contained in the total length 

 (without caudal) 5^ times, the length of the head 4f . The 

 diameter of the eye is contained in tlie length of the head 5^ 

 times, the width of the interorbital space 2^. Adipose eyelid 

 not developed ; the prjeorbital is emarginate and distinctly 

 denticulated ; snout longer than the orbit ; upper lip thin ; 

 extremity of the maxillary not hidden. There are twenty- 

 three scales between the snout and the first dorsal fin ; no 

 elongate scale in the axil. Dorsal fins nearly equal in height ; 

 the spines are rather slender, and the first is rather shorter

 the dorsal nor the anal fins are scaly, the latter commences 

 distinctly in advance of the soft dorsal. Caudal emarginate. 

 Pectoral as long as the head, without snout. Coloration 

 uniform.
