Length of head 3.5 ; depth of body 2-1, and length of caudal 

 4-2 in the total length. Eyes on the right side, separated by a 

 smooth narrow space, one-fourth the diameter of the eye ; the 

 lower eye is noticeably in advance of the upper and the diameter 

 is 4 '8 in the length of the head, or but slightly less than that of 

 the snout ; the latter is produced into a fleshy process directed 

 downwards over the mouth. The anterior nostril may be closed 

 by a trilobed process. The hinder one lies posterior to the front 

 edge of the lower eye and is a simple pore. The mouth is of 

 moderate size extending to nearly below the anterior margin of 

 the eye : it is more extensive on the blind side, and has two 

 rows of teeth in each jaw ; the nostrils have a higher and 

 more anterior position than on the right side. Gill-raker& 

 small, conical, and smooth, slightly fenibriated on the inner 

 side ; about thirteen in number on the lower limb, scarcel}^ 

 developed on the hinder one. Gills three and a half, a slit 

 behind the last, equal to the diameter of the eye. The gill 

 openings are small, not extending to the ujDper angle of the 

 pectoral above, and closed below the preopercular angle beneath. 



Fins.— The dorsal commences on the rostral process, about an 

 eye diameter from its extremity. Though partially free anteriorly, 

 all the rays are connected by membrane. They are highest about 

 the middle of the fin where they form a conspicuous angle, the 

 thirty-fifth or longest ray being 1*9 in the length of the head. 

 The rays are continued to within an eye-diameter of the caudal 

 rays. The ventral commences beneath the middle of the eye and 

 is quite continuous with tlie anal, the apparent omission of one 

 ray only indicating the distinction. The vent is situated on the 

 left side contiguous to this space. The anal is similar to the 

 dorsal the sixteenth ray being the longest. The right jiectoral is
