Var. aaaan. Depth into length 5 times; length head into same 4 times; 
6-6 
scales ee color silvery, a double row of black specks on lateral line. Very 
abundant in the head waters of the Catawba River. This fish when taken 
from the water, always sustains a rupture of some of the branches of the 
ophthalmic artery by which blood is suffused beneath the cornea. The 
altered condition of pressure on transfer to a rare medium, is no doubt the 
cause. 
Also from the Neuse River, near Raleigh.

Very abundant in the French Broad River ; a variety with large eye in 
a tributary of the Clinch.

Abundant in the waters of the tributaries of the French Broad River.

This species is in most characters related to the Hypsilepides, and it 
combines remarkably the characters of the H. cornutus, H. analostanus, 
and H. dipkemia. Thus it has the head of the first, the form, with 
milky paired, and black spotted dorsal of the second, and the long anal of 
the third. As the teeth are without masticatory surface, I refer it for 
the present to this genus. 
The extremity of the muzzle descends obliquely to the mouth, which is 
itself oblique, the end of the maxillary descending toa line from the an- 
terior margin of the orbit. The mandibular and premaxillary margins 
are in the same vertical line when the mouth is closed. The diameter of 
the eye ball enters the length of the head 3.6 times, and 1.25 times in 
interorbital width. Length of head four times in length, depth about the 
same. The body is therefore rather deep and compressed. Teeth sharp, 
hooked, 4.1—1.4. Radii D. I. 8, A. I. 10. V. 8. The extremities of the 
pectorals barely reach the ventrals, and the ventrals attain the anal.

In coloration this is again one of the finest of our Cyprinid. Specimens 
taken in autumn were steel blue above, the scales darker edged ; the belly 
silver. The muzzle and upper lip to the end of the maxillary, are vermil-
