Length of head contained 4J times in that of the trunk 5 head and 

 trunk together shorter than tail, and contained 2^^ to 2^ times in total 

 length. Pectoral very small, its length about equal to depth of gill- 

 opening. Dorsal beginning close behind nape, much in front of gill- 

 opening; fins low; tail pointed, the tip sharp. 



Color light olive ; sides each with three series of large round brown 

 spots, those of the two npper series of equal size, those of lower scarcely 

 half as large, faint, and often obsolete anteriorly ; the spots irregular in 

 their arrangement, those of the npper series usually twice as numerous 

 as those of the next; those of the upper series along base of dorsal fin 

 extending partly on the base of the fin; lower series of spots along base 

 of anal, some of them extending on the fin or even entirely upon it ; on 

 the belly are sometimes small dark spots scarcely arranged in series. 

 Dorsal fin with a terminal series of dark spots, which are partly con-

Cleft of mouth wide, the snout much overlapping the lower jaw; 

 length of gape from tip of snout to angle of mouth contained 2f times 

 in length of head. Teeth small, sharp, subequal, in two somewhat irreg- 

 ular rows on each of the dentigerous bones ; points of the teeth direcfed 

 backwards; no canines; patch of vomerine teeth long, the two series 

 converging backwards. Eye large, its diameter two-thirds the inter- 

 orbital width, -which is slightly less than length of snout. Anterior pair 

 of nostrils at end of anterior third of snout, in a short tube, which is 

 less than one-third diameter of orbit and widened at tip. Posterior 

 nostrils large, below the anterior margin of the orbit, not tubular, but 

 the margin with free dermal flails. 



Gill-opening one-third wider than eye, its upper edge slightly above 

 middle of base of pectoral; length of slits slightly greater than the 

 isthmus between them. 



Tail long, very nearly twice as long as rest of body. Length of head 

 contained 2^ times in that of trunk. 



Pectoral fin well developed, its length 2i in length of head, in adults; 

 proportionally longer in the young. Dorsal fin beginning slightly in 

 advance of tip of pectorals, well developed, the rays distinct. Tix) of
