The height of the body is somewhat less than one-third of the 

 total length (without caudal), the length of the head rather more 

 than one-fourth ; head thick, snout obtuse. The diameter of the eye 

 equals the length of the snout, is rather more than one-half of the 

 width of the interorbital space, and contained thrice and two-thirds 

 in the length of the head. Dorsal and anal elevated in males, and 

 extending to the caudal, if laid backwards. In males the origin of 

 the dorsal fin is midway between the root of the caudal and the 

 occiput, and corresponds to the eleventh scale of the lateral line ; in 

 females the dorsal is situated further backwards, its origin being 

 midway between the gill-opening and the root of the cauda^, but 

 also corresponding to the eleventh scale of the lateral line. The first 

 anal ray is below the fifth of the dorsal. Caudal truncated. Man- 

 dible about as long as eye. Light-greenish olive. 



Males with nine or ten very distinct silvery cross bars, each about 

 as broad as a scale ; anterior dorsal rays black ; caudal with a rather 

 indistinct blackish band across its hinder half. 



Fnnales silvery on the side, with more or less numerous narrow 

 black vertical stripes, which do not extend on to the back or to the 

 belly. 



In the yodiif' the silvery cross bars and black vertical stripes are 

 as frequently present as absent. 



Brackish or saline waters of Southern Europe and North Africa.
