SYNOPSIS OF THE CYPRINIIVE OF PENNSYLVANIA. 



latter to base of tail equal from former point to half way between end of muzzle and narcs. Scales small, with 

 especially strong concentric lines, 10—62—5. Dorsal high 1.8 ; caudal deeply furcate, 19 ; anal rather elongate, 

 1.8 f . V. 8, not reaching vent ; P. 14, elongate. Total length three inches, large specimens four and a half inches. 



In spirits, rufus brown above halfway to the lateral line; a dark shade from end of muzzle to tail, covered with 

 silvery, the latter extending to the belly. Sides punctulate anteriorly. 



In spring and summer the belly and sides to above the lateral line are of a bright crimson. Teeth in two speci- 

 mens 2.5 — 4.1. 



This species occurs in some of the tributaries of the Ohio, and has not been seen in any 

 of the waters more eastwardly. It has apparently been formerly not distinguished prop- 

 erly from the C. elongatus of Dr. Kirtland, unless it be the Leuciscus productus of Dr. 

 Storer. Kirtland's description applies equally well to both species, while his figure does 

 not represent the proriger. I have seen several specimens of the C. elongatum, which ex- 

 hibits a shorter head and jaw than the present fish, but have none at hand from which to 

 draw a description. It occurs in some Western States, and probably also in Western 

 Pennsylvania.

Orbit one-third head, which is equal greatest depth, and one-fifth length, including cau- 

 dal. Mandible projecting beyond premaxillary ; maxillary extending to opposite pupil. 

 Posterior angle of operculum right. Caudal fin rather elongate ; its furcation one-third its 

 depth. Anterior dorsal rays two and one-fifth times in length from their basis to that of 

 caudal ; longest anals two and one-half the same distance. Dorsal outline arched to first 

 dorsal ray; caudal peduncle rather narrow, its depth three and one-quarter times from median base of caudal to 

 first anal raj. The operculum is considerably longer than high ; the orbit round, as long as the muzzle in advance 

 of it, and nearly equal the interorbital width. Dorsal and anal fins with short basis and long rays, latter nearly as 

 long as former; basis of dorsal half its longest rays ; a little more than half same in anal fin, ventrals reaching anal 

 and pectorals ventrals. A male in breeding dress is quite rugose, like the Hypsilepis diplacmia, with tubercular 

 points on the back and sides, and the rays of the dorsal and anal fins. The thoracic and branchiostegal regions, 

 with the lower part of the operculum, are thickly studded, and on the top of the head they are of equal size and 

 irregularly arranged to about six in transverse directions. The fissure of the mouth is large, the end of the max- 

 illary opposite the anterior rim of the pupil. The lateral line is more strongly decurved in this species than the 

 last, and rises distinctly opposite the origin of the ventrals. 



Above dusky to the lateral line, with a light (? yellow or red) band from the superior opercular angle, above 

 the lateral line to the tail. Below lateral line, chin, suborbital, and subopcreular region yellowish ; red in spring. 

 Dentition 2.5—4.2. 



I have several specimens of this handsome species from the Octoraro, a fine tributary 

 of the Susquehanna, which separates Chester and Lancaster Counties. I have also seen 

 a specimen from the White Clay Creek, in Chester County, tributary of the Delaware,
