 D. 6 I 11. A. 11. L. lat. 60. 



Fifteen longitudinal series of scales between the second dorsal fin 

 and the anal. Scales on the neck much smaller than those on the 

 tail. The height of the body is contained six times and a half in the 

 total length, the length of the head three times and a half. The 

 head is flat, depressed, as broad as high, with the snout elongate. 

 Cleft of the mouth horizontal, the upper jaw being the longer ; Kps 

 thick ; the eye is situated in the middle of the length of the head. 

 AU the teeth small ; none of the outer series enlarged. The maxillary 

 extends to, or shghtly beyond, the vertical from the anterior margia 

 of the eye. The width of the interorbital space equals the diameter 

 of the eye, which (in mature specimens) is one-sixth of the length of 

 the head. The head is naked ; scales on the anterior part of the 

 body smaller than on the posterior. The distance of the fii-st dorsal 

 fin from the eye equals that of the snout from the prseoperculum. 

 The dorsal fins are lower than the body ; caudal rounded, its length 

 being somewhat less than one-fifth of the total ; the ventral fin ter- 

 minates at a great distance from the anus, and has a broad basal mem- 

 brane. Yellowish or brownish : sides of the head and body with 

 irregular black spots, the spots forming a distinct longitudinal band 

 between the bases of the pectoral and caudal fins ; root of the caudal 

 with a round deep-black spot ; a black streak superiorly on the base 

 of the pectoral. Dorsal, caudal, and pectoral fins dotted with brown, 

 the dots being arranged in longitudinal series on the first, and in 

 transverse ones on the two latter ; ventral and anal blackish.
