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. cornutus which I have examined. 



42. LUXILUS EOSEUS, sp. nov. 



Another handsome species, related to the last, but still move Eyhopsis- 

 like. 



Body short, thick, and stout, much as ixiHyhorliynclms notatus; head 

 3§ in length, depth 4J; head rather short, thick, bluntly rounded; 

 mouth moderate, slightly oblique ; jaws about equal, the lower shutting 

 within the upper in closed 'mouth j 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 H. chrosomus, 

 H. 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 jioints; 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 2^ inches in length. 



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



This small species forms a transition between Luxilus and Hyhopsis. 



Habitat. — Notalbany Eiver, near Tickfaw, La. ; collected December, 

 1876, by Dr. T. H. Bean. The types are now in the United States Na- 

 tional Museum. 



43. OYPEINELLA CALLIUEA, 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, If in interor- 

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