. CYPRINID^. 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 

 L. cornutiis which I have examined. 



42. LUXILUS ROSEUS, sp. nov. 



Another handsome species, related to the last, but still moie Eybopsis- 

 like. 



Body short, thick, and stout, much as in. Eyborhynchus notatus; head 

 3J in length, depth 4^; 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 Eybopsis, such as if. chrosomus, 

 E. rubricroceus, &c. 



Fin-rays: — Dorsal I, 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 2J inches in length. 



Teeth 2, 4-4, 2, with developed grinding surfaces. 



This small species forms a transition between Luxilus and Eybopsis. 



^ffaMtot— 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, 1^ in muzzle, 1? in interor- 

 bital width. Head 4f in length ; depth 3^ to 4.
