The height of the body is one-half or less than one-half of the total 

 length (without caudal), the length of the head two-sevenths. The 

 greatest depth between the anal fin and the straight portion of the 

 lateral line is less than the length of the head. Scales minute, smooth ; 

 cheeks with rudimentary scales ; interorbital space naked. A series 

 of six obtuse bony tubercles runs from the eye to the origin of the 

 lateral line. iJase of the fins and lateral line smooth ; the latter is 

 slightly curved above the pectoral, the depth of the curve being less 

 than the width of the base of the pectoral. Snout nearly as long as 

 the eye, the diameter of which is one-fifth or one-sixth of the length 

 of the head. Lower jaw prominent ; maxillary as long as the eye. 

 Upper jaw with a series of about twenty-four narrow, closelj^-set 

 incisor-like teeth on the blind side, those of the other side being small 

 and few in number. Eyes separated by a verv narrow smooth ridge ; 

 • the lower eye scarcely in advance of the othei . The dorsal commences 

 above the middle of the eye and terminates at a short distance from 

 the caudal, that disl,ancc being much less than the depth of the free 

 portion of the tail. The length of the pectoral is contained twice and 

 a third in that of the head. The dorsal rays about the thirty-eighth 

 are the longest, more than half as long as the head. A spine before 



* Tliis variety is said to have .*]' tcctli on the blind side of the intermaxillary.
