 head, which is one-fifth of the total (without caudal). Snout pro- 

 duced, obtuse, a little longer than the postorbital portion of the head. 

 Eye small, with free orbital rim, its length being equal to the width 

 of the interorbital space. Length of the pectoral about one-half of 

 the distance of its root from the ventral. Upper margin of the dorsal 

 fin obliquely descending backwards. Back and sides irregularly 

 mottled with dark brown ; generally a blackish blotch on the lower

 caudal. The height of the body is considerably less than the length 

 of the head, which is contained five times and one-fourtli in the total 

 (without caudal). Snout of moderate length, a little shorter than 

 the postorbital portion of the head. Eye small, with a free circular 

 eyelid, its diameter not being quite as wide as tlie interorbital space. 

 Length of the pectoral more than one-half of the distance of its base 

 from the ventral. Upper margin of the dorsal fin straight, oblique.
