cobtained 3J times in the total length to caudal base. The longest anal 

 ray is slightly longer than the longest dorsal ray. The caudal fin is 

 pointed, the middle caudal ray being one-fourth as long as the total 

 length to caudal base. The pectoral of the eyed side is somewhat longer 

 than that of the blind side, its length being contained 1^ times in that 

 of the head. The ventral of the eyed side is inserted on the ridge of 

 the abdomen; it is shorter than that of the blind side, its length being 

 contained 2f times in the distance of its origin from the tip of the snout. 



The color in spirits is a light olive-brown. The body with .some 

 20 dark brown spots, the largest about as large as the eye. Four of
