The height of the body is contained thrice and three-fourths in 

 the total length (mthout caudal), the length of the head foiu" times. 

 Head three-fourths as deep as long. The diameter of the eye is 

 less than one-foiu-th of the length of the head, and much less than 

 the width of the interorbital space, "which is convex, and equals the 

 length of the snout. 8nout obtuse, mouth of moderate width, jaws 

 even in front. Suborbital bones very narrow ; prceorbital as long as 

 deep, much larger than the postorbital, which is not wider than the 

 preceding bone. The origin of the dorsal fin is nearly opposite to that 

 of the ventrals, and a little nearer to the end of the snout than to the 

 root of the caudal. Caudal fin forked. The pectoral fins terminate 

 at some distance from the ventrals. Scales much higher than long on 

 the side of the body, and much larger than those on the back and 

 belly. There are three longitudinal series of scales between the lateral 

 line and ventral fin. Coloration of preserved specimens uniform. 



Pharyngeal teeth compressed, hooked, 4 . 1 — 1 or 2 . 4.

Head and body oblong. The height of the body is somewhat 

 more than one-filth of the total length (without caudal), the length 

 of the head nearly one-fourth. Head two-thirds as deep as long. 

 Eye large, a little less than one-thii'd of the length of the head, 

 equal to the width of the interorbital space, and rather longer than 

 the snout. Snout obtuse, overlapping the small horizontal mouth ; 

 suborbital bones very narrow ; prceorbital a little longer than deep, 

 larger than the postorbital. The origin'' of the dorsal fin is opposite 

 to that of the ventrals, and midway between the end of the snout and 

 root of the caudal. Caudal fin deeply forked. The pectoral fins ter- 

 minate at some distance fi.'om the ventrals. There are three and a half 

 longitudinal series of scales between the lateral line and ventral fin. 

 Silvery ; each scale of the lateral line with more or less conspicuous 

 brown dots, sometimes forming a dark longitudinal lateral band. 



Pharyngeal teeth slightly compressed and hooked, 4 . 1 or * — 1 . 4.

* The inner tooth is frequently deciduous.
