Depth equal length head; last dorsal ray less than half first; muzzle 
broad, beards small. C. HYPSINOTUS.

Spec. nov. 
This is a peculiar species of slender proportions. The top of the head 
is gently decurved to a muzzle which scarcely overhangs the thick, pro- 
jectile upper maxillary arch. The mouth is entirely horizontal, and the ex- 
tremity of the maxillary bone attains the line of the orbit. The latter 
enters the length of the head 3.75 times, and is just exceeded by the inter- 
orbital width. The head enters length to origin caudal from 4 to 4.5 
times. Front arched in transverse section. Depth 5.5 times in length. 
The dorsal line is nearly plane, and the elevation of the first dorsal] rays 
is contained twice in the length from its base to the anterior rim of the 
pupil: it stands over origin of ventral. Scales large 6—34-5—4. Radii 
D.8; A.8.

This fish is silvery from the middle of the sides downwards. In some 
specimens there are numerous blackish scales above the lateral line, which 
are arranged so as to form indistinct cross-bars in life; in other specimens 
the color is quite transparent, indicating two varieties. The latter are 
frequently a little more slender than the former. 
The beards of this species are relatively longer than in any other spe- 
cies of the genus. The prominent lips remind one of Phenacobius. The 
species is not uncommon on the bottom in clear and rapid creeks which 
flow into the upper waters of the Catawba River, in Macdowell and Burke 
Counties, N. Ca.

Spec. nov. 
This little species has a stout robust form. The head and muzzle are 
broad and flat ; the muzzle is not prominent; the mouth is inferior and 
horizontal ; the maxillary just reaches the line of the orbit. The form is 
characterized in the genus by the gradual elevation of the dorsal line to 
the base of the first ray of the dorsal fin, and its rather abrupt descent 
from that point. The base of this fin is thus oblique and the distal out- 
line is vertical ; the posterior ray being less than half as long as the ante- 
rior. This produces a characteristic appearance. The head is short. 
and enters the length 3/75 times, equalling the depth. Body compressed. 
Orbit 3.5 times in length head, and once in inter-orbital space. Lips, es- 
pecially inferior, thin ; beards small. Scales, 4-5-—-88-41——-3._ Teeth 
4.1——1. 4. Dorsal fin originating a little in advance of above ventrals ; 
8. A. smaller than dorsal, 8.
