Vert. 22/21. 

 Body rather elongate, its depth being one-fourth or somewhat 

 less than one-fourth, of the total length (without caudal). Snout 

 as long as, or rather longer than, the eye ; cleft of the mouth mo- 

 derately oblique, the jaws being even in front, or the lower rather 

 the longer. The abdomen is sUghtly compressed behind the ven- 

 trals, the scales reaching across the keel. There are three lonoi- 

 tudinal series of scales between the lateral line and ventral fin. The 

 origin of the anal fin is behind the end of the dorsal. Scales of 

 adult examples with a dark margin. 



This hybrid appears to occur in all localities inhabited by AJ- 

 buniHS luchlus and L. dobula.

 fourth of the total (without caudal). Head rather broad, the width 

 of the interorbital space being contained tiuice ami two-thirds in the 

 length of the head. The diameter of the eye is less than the extent 

 of the snout, and contained four times and two-thirds in the length 

 of the head, and once and two-thirds in tl;c width of the interorbital
