We cannot hesitate to separate this species from the fore- 

 going. Of C. calm'itanus we have examined several liundred 

 specimens without discovering any appreciable difference from 

 the description of Dr. Giinther. But we have received from 

 the spring of Taguin two males, the lengths of which are 2 J 

 and 3^ centimetres respectively, which correspond with 

 Valenciennes's description and figure quite sufficiently for 

 identification with them. 



In general appearance they resemble more nearly the female 

 than the male of C. calaritanus ; but they differ from both sexes 

 of that fish in the number of scales on the lateral line, which 

 are in 30 series. 



The height of the body is ^ of the total length without 

 caudal ; the length of the head is contained 3^ times in the 

 same. Diameter of eye rather more than length of snout, and 

 equal to half the breadth of the interorbital space ; it is one- 

 third of the length of the head. Dorsal and anal as much 

 elevated as in the female of C. calaritanus^ but less than in 

 the male of that species. 



The first dorsal ray is inserted midway between the root of 

 the caudal and the gill-opening, and corresponds to the twelfth 

 scale of the lateral line. The first anal ray is below the second 

 or third of the dorsal. Caudal truncated. 



Colour : greenish- olive, minutely spotted with black ; about 

 eighteen narrow silyery cross bands on the sides ; dorsal, anal, 

 and caudal with very distinct black cross bands.

The genus Tellia'^ is very similar to Cyprinodon^ but has 

 no ventral fins ; the mouth is protractile, the lower jaw pro- 

 jects beyond the upper, the teeth are tricuspid in a single 

 series in each jaw. 



The height of the body in females is about ^, and in males 

 somewhat less than \ of the total length ; the length of the 

 head is contained about 3^ times in the same. The diameter 



* So called, perhaps, because it has never been found in the Tell, but 

 only on the High Plateaux.
