Fishes of Cayuga Lake Basin. 303 



Family VII. CYPRINIDJE. 



15. PIIflEPHAIiES PROIflEIiASt Raflnesque. 



(Black-headed Minnow.) 

 A., 288. B., 158. C, 22. 



Length of largest specimen, about 65 cm. 



Head, 4 in the length of the body; depth 3| to 4. 



Dorsal rays, 1-8; anal rays, 7; scales in the lateral line, 42-44. 



Body elongate, robust; dorsal region rather prominent, more so than 

 in P. notatus. 



Snout bluntish, the mouth small and terminal, its gape forming a 

 slight angle with the axis of the body. Margin of upper lip on a level 

 with the ventral surface of the pupil; maxillary reaching about | dis- 

 tance to vertical from the cephalic margin of the orbit. Premaxil- 

 laries protractile. Lateral line incomplete, pores on about 15 scales. 

 Scales between the dorsal fin and the nape small and crowded. 



Peritoneum black; alimentary canal about 2^ times the length of the 

 body. 



Teeth, 4-4, not hooked, all with the grinding surface developed. 



Color olivaceous, somewhat silvery, darker on the sides. 



The dark bar across the dorsal fin not very distinct; a faint dark spot 

 at the base of the caudal. 



The above description is based upon ten specimens taken from Fall 

 Creek, between Triphammer Falls and Forest Home. I found this 

 species only in this one locality. 



This specifts is easily distinguished from others of the Cayuga 

 cyprinoids by the very long intestine. Apparently not com- 

 moD.

Length of largest specimens, about 7 cm. 



Head, 4^ in the length of the body; depth 4 to 5. 



Scales in the lateral line, 42-44.

Snout very blunt, mouth small, the gape parallel with the axis of 

 the body; the lower jaw the shorter, slightly overhung by the very 

 blunt snout. 



Margin of the upper lip*on a level with the ventral surface of the 

 orbit; end of the maxillary reaching | distance to vertical from the 

 cephalic margin of the orbit.
