THE CYPRINODONTS. 27 



length are more nearly uniform in color. An individual of about one inch 

 has the dorsal blotches more distinct and separated from the lateral by a 

 light stripe, below which there is a series of eight triangular or v-shaped 

 blotches, some of which coalesce. Below the eye downward and forward 

 a brown spot extends to the chin. On the cheeks, snout, and top of head 

 there are dots or mottlings of darker.

Body and head compressed ; crown flattened ; caudal pedicel deep, taper- 

 ing more, in a lateral view, than on other species ; back arched, descending 

 gradually toward the caudal from the origin of the dorsal. Depth one thii-d 

 of total length ; head one third of distance from snout to base of caudal. 

 Snout short, blunt ; chin steep. Mouth medium, oblique, opening upward ; 

 lower jaws longer, firmly united ; upper shorter, protractile. Teeth in a 

 single series on each jaw, tricuspid. Eye large, one third longer than snout, 

 one third of head, nearly as wide as forehead. Dorsal elongate, originating 

 about midway from the middle of the eye to the base of the caudal ; base 

 little shorter than head, extending little backward of that of anal ; first ray 

 strong, spine-like, following rays weak and slender. Anal small, originating 

 in front of a vertical from the middle of the dorsal base. Ventrals small, 

 not reaching anal. Pectorals reaching bases of ventrals. Caudal large, 

 convex on hind margin. Scales large, humeral scales larger. Intestine 

 nearly thrice the length of the body. 



Brownish to olivaceous, with a series of six or eight brown transverse 

 blotches on the back, and another series, opposite those of the former, along 

 the lateral line ; with a black spot below the eye ; with or without a blackish 

 spot on the hindmost rays of the dorsal , and with a large blackish spot, in 

 the lateral series, on the middle of the side below the dorsal spine. Fins,
