The height of the body is a little less than the length of the head, 

 and somewhat more than one-fouiih of the total (with the caudal). 

 The diameter of the eye equals the length of the snout, and is nearly 

 one-fourth of that of the head. Dorsal and anal fins well developed. 

 The origin of the dorsal is nearer to the root of the caudal than to 

 the gill-opening, and opposite to that of the anal. Caudal rounded. 

 Scales of the upper part of the trunk with a blackish spot at the 

 base, the spots being more distinct in the male than in the female.

BeUotti, Mem. Accad. Sc. Torin. 1858, xvii. p. clx, considers this 

 species to be the female of Cyprinodon iberus — which is evidently 

 an error.

The height of the body is about equal to the length of the head, 

 which is contained thrice and one-third in the total length (without 

 caudal). Head thick, short, with the snout obtuse, the lower jaw 

 projecting beyond the upper. Diameter of the eye about equal to 

 the extent of the snout, one-half of the interorbital space, and two- 

 ninths of the length of the head. The origin of the dorsal fin is 

 midway between the root of the caudal and the eye in males, and 

 equidistant between the root of the caudal and the praioperculum in 

 females. The origin of the anal is opposite to that of the dorsal in 

 males, and somewhat more backwards in females, in which, besides, 

 the anterior anal rays are stiiF and inflexible. The male has the 

 vertical tins and the pectorals much more elongate than the female. 

 Specimens of this sex have all the scales provided with a more or 

 less broad, beautiful carmine-red margin. Sides of the head and 

 the dorsal and anal fins with carmine-red spots. Caudal entirely 

 red. Females have the tail and the base of the anal and caudal 

 dotted with black.
