IN THE ALLEGHENY REGION OF SOUTH-WESTERN VIRGINIA. 231 



Hybopsis lojstgiceps Cope, sp. iiov. 



Form elongate, caudal peduncle not contracted; profile flat to nares, then obliquely 

 descending; vei'tex gently convex; orbit •25 greater than frontal width, longer than 

 deep. Preorbital bone much longer than deep ; maxillary not attaining line of orbit. 

 Dorsal fin mostly nearer end of muzzle than basis of caudal, in small specimens equi- 

 distant. Inferior fins short, none reaching the following. Fourteen rows scales 

 anterior to dorsal fin. Operculum considerably larger than posterior margin. 



Total length 2 in. 4 lin. ; do. to basis dorsal 13-5 lin. ; depth at first anal ray 4-G 1. 



Color in life translucent, with a well-marked lateral silver band, which is marked 

 by a black speck at the origin of each tube of the lateral line. 



This species is moderately abundant in the head-waters of the Roanoke in 

 Montgomery, and of the James in Giles County, Va. 



Hybopsis spectrunculus Cope, sp. nov. 



This species can be recognized by its broad head, remarkably thick muzzle, large 

 eye, and olivaceous colors. 



Mouth slightly oblique, maxillary attaining line of orbit; preorbital bone longer 

 than high. Head nearly broad as deep ; depth at posterior margin orbit equal length 

 from end muzzle to posterior margin pupil. Dorsal nearer caudal than end of muzzle, 

 former distance measui'ing to anterior to orbit in latter. 



Total length 2 in. 6"75 lines; depth at dorsal 4 lin.; at last anal ray 2--j; width 

 of parietal region 3 lines. 



Color olivaceous, below silvery white ; a leaden band along the sides, and 

 conspicuous black spot at base of caudal. Head above, and margins of scales above 

 the lateral line, with bases of dorsal and anal fins, blackish. Edges of pectorals, 

 centres of ventrals and anal orange; dorsal membrane red-orange. 



Inhabits in abundance Bear Creek, a tributary of the middle fork of the Holston 

 River, in Smyth Co., Va., also probably the adjacent tributaries of the same stream, 

 the Hungrysmother and Chilohoway Creeks. 



Hybopsis rubricroceus Cope, sp. nov. 



This species has the general form of Eypsileins cornuius, having a less depressed 

 form than the species of the preceding sections of the genus. The lateral line is 

 distinctly decurved. The colors are most brilliant, presenting a marked contrast to 

 those of other species, excepting the H. chalybseus mihi, type of the section. 

 The latter fish I found last spring in great abundance in the dam of Brown's Mills, 

 in middle New Jersey. The females were filled with ova, which they were about to 

 deposit. The largest specimens did not attain more than '25 inch above the
