THE CYPRINODONTS. 133 



Body rounded forward, compressed posteriorly; depth one fifth of the 

 total length. Head depressed, crown flat. Eye two thirds of the inter- 

 orbital space, two sevenths of the head. Lower jaw little longer than the 

 upper. Teeth small, in bands, outer series larger. Dorsal origin midway 

 from the edge of the opercle to the end of the caudal, slightly backward 

 from the middle of the anal. Pectorals terminating far in front of the 

 origin of ventrals, which are small. Caudal rounded, one seventh of the 

 total. 



Body brownish, lighter below. Dorsal and anal with brownish dots on a 

 yellowish ground. A large spot of black on the neck. 



Madagascar. (Sauvage.) 



The published figure of this fish shows the snout to differ from that of 

 the typical Haplochili. The intermaxillaries are apparently similar to those 

 of Fundulus. Nothing is said concerning pseudobranchiaa. Until we know 

 more of its characters the position of this species must remain doubtful.

D. 8; A. 14; V. 6; LI. 31; Ltr. 8. 



Body elongate, depth five, and head three and two thirds times in the 

 length to the base of the caudal. Head long, depressed, with flat crown. 

 Snout long, broad; upper jaw little longer. Eye in the middle of the length of 

 the head, of which it is two ninths, more than half of the interorbital space. 

 Fins well developed ; dorsal origin little nearer to end of caudal than to gill 

 opening, above twenty-third scale of the lateral line ; anal entirely forward 

 of dorsal and behind the middle of the total length ; pectorals reaching the 

 ventrals ; ventral reaching the vent ; caudal rounded. 



Light brownish olive ; caudal and inner portions of dorsal and anal with 

 blackish cross bands or series of spots ; basal half of caudal with round spots 

 of light color. The specimens described were six inches in length, probably 

 males.
