8. CYPRINELLA WHIPPLIl, G/d. 

 Plate LVIII, Figs. 6—10. 



Spec. Char. — Body elongated and siib-fusiform. Peduncle of tlie tail stoutish. Head constituting the fifth of the entire 

 length. Eye rather large ; its diameter entering nearly four times in the length of the side of the head. Snout sub-conical and 

 tapering ; gape of the mouth nearly horizontal ; posterior extremity of ma.xillar bone corresponding to a vertical line drawn at 

 the anterior rim of the orbit. Anterior margin of dorsal fin nearer the insertion of the caudal than the tip of the snout. Origin 

 of ventrals situated under the anterior edge of the dorsal. Pectorals and ventrals slender. Reddish brown above ; golden yellow 

 beneath ; a black patch at the posterior margin of the dorsal fin. 



SiN.— Cyprinella whipplii, Grd. in Proc. Acad. Nat. Sc. Philad. VIII, 1856, 198. 



Gracefully elongated and sub-fusiform. Dor.sal region slightly arched upon the insertion of 

 the fin. Greatest depth forming a little more than the fifth of the total length, whilst the head, 

 which is sub-conical, constitutes a little less than the fifth of the same dimension. The eye is 

 rather large, its diameter entering about four times in the length of the side of the head. A very 

 characteristic feature consists in a very high dorsal fin, rounded upon its upper margin. The 

 origin of the ventral fin is situated opposite the anterior margin of the dorsal or very slightly in 

 advance of it. The anal fin is very much developed also, somewhat deeper than long, its anterior 

 margin being nearer the fork of the caudal than the isthmus. The ventrals and pectorals are 

 slender and lanceolated, the tips of the former overlapping the vent and reaching the origin of 

 the anal, whilst the latter are far from approximating the insertion of the ventrals. 

 D 2, 8 + 1 ; A 2, 9 + 1 ; C 8, 1, 9, 8, 1, 6 ; V 1, 8 ; P 14. 



The scales are of moderate development, and the lateral line, as usual, deflexed upon the 

 abdomen, approximates more the ventrals than the dorsal fin. 



The color is reddish brown above ; yellowish beneath with a golden reflect. A black patch 

 may be observed at the posterior margin of the dorsal fin ; the upper fins assuming a greyish 

 olive tint, the lower fins a light yellowish one.
