THE CYPRINODONTS. I33 



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 pseudobranchiaj. Until we know 

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