5. Leuciscus copei (Jordan & Gilbert). 
Common; axil in male deep scarlet. 
6. Agosia adobe Jordan and Everniaun, sp. nov. 
Very abundant in the Sevier Eiver. 
The Agosia of the Sevier River seems to be certainly distinct from Agosia, nubila and 
from all the other species known to me. I am utterly unable to identify it with any 
of the species described by Cope, nor can I see how most of these species ditter from 
each other or from A. nubila. We therefore propose a new name for the Sevier species 
In allusion to the color of the fish and the bottoms it frequents. 
Head 3§ to 3| in length; depth 4^ to 5. D. 8 ; A. 7. Scales 12-63 to 70-10. 
Length of types 2 to 4 inches. 
Body rather slender and elongate, formed as in Bhinichthys. Head long and low, 
sharp in profile, the anterior profile forming an even and gentle curve from tip of snout 
to front of dorsal. Snout sharp, long, more than J of head, 2fto2|, usually 2§, its tip 
projecting considerably beyond the thick upper li]). Mouth rather larger than in A. nu- 
the maxillary extending to behind nostril; barbel well developed. Eye small, 
about two in snout, 5 to 5^ in head. Lateral line comjdete. Dorsal inserted midway 
between front of eye and base of caudal. Pectoral usually shortish and not reaching 
ventrals, but sometimes passing them. Fins rather high. Caudal well forked, the 
lower lobe slightly longest. 
Color grayish-olivaceous above with a dark lateral baud, fins and belly pale ; 
back with some dark dots. 
7. CottuB bairdi punctulatus (Gill). { Urmiidea wheeleri Co'pe.) 
Abundant in Sevier River. Color clay-gray, everywhere finely reticulate with 
olive, the pattern on head very fine. Skin perfectly smooth. These specimens agree 
fully with others from Gibbon River, except in the shade of the ground color, which 
in the Sevier corresponds to the bottom of adobe.
