CYPRINIDZ. 61 
Many specimens in United States National Museum; collected near 
Bayfield, Wis., by J. W. Milner. 
This species seems to be distinct from all the numerous varieties of 
I. cornutus which I have examined. 
42. LUXILUS ROSEUS, sp. nov. 
Another handsome species, related to the last, but still more Hybopsis- 
like. 
Body short, thick, and stout, much as in. Hyborhynchus notatus ; head 
5g in length, depth 44; head rather short, thick, bluntly rounded; 
mouth moderate, slightly oblique; jaws about equal, the lower shutting 
within the upper in closed mouth; eye large, nearly 3 in head, about 
equal to snout, a little less than the broad interorbital space; scales 
large, 5-38-5, 15 before the dorsal fin, those along the sides with the 
exposed surfaces somewhat narrowed, but not very decidedly so, the 
arrangement being about midway between that observed in L. cornutus 
and that of the colored species of Hybopsis, such as H. chrosomus, 
H. rubricroceus, &c. 
Fin-rays:—Dorsal [, 8. Anal I, 7. Dorsal fin high, inserted directly 
over ventrals, midway between snout and caudal; pectorals not reach- 
ing ventrals the latter to vent. 
Color olivaceous above; scales dark-edged, a broad plumbeous lateral 
band passing through eye; lips black, a dark caudal spot, a dark verte- 
bral line; anal region dusted with black points; cheeks and belly sil- 
very ; dorsal, anal, caudal, and most of pectorals rosy red; iris, top of 
head, and tip of snout also red; no tubercles on the type-specimens, 
which are probably immature, being about 24 inches in length. 
Teeth 2, 4-4, 2, with developed grinding surfaces. 
This small species forms a transition between Luxilus and Hybopsis. 
Habitat.—Notalbany River, near Tickfaw, La.; collected December, 
1876, by Dr. T. H. Bean. The types are now in the United States Na- 
tional Museum. 
43. CYPRINELLA CALLIURA, sp. nov. 
Body elongated, compressed, elevated in the middle, the profile be- 
fore dorsal curved, and the snout projecting, forming a decided angle. 
Head convex above, densely tuberculate ; muzzle rather pointed, over- 
hanging the oblique mouth. Eye 4 in head, 14 in muzzle, 12 in interor- 
bital width. Head 42 in length; depth 33 to 4.
