Body rather short and thick-set, the "back not greatly arched. Head 

 rather heavy, the muzzle blunt. Mouth moderate, the jaws equal, the 

 maxillary not reaching orbit. Lateral line decurved. Head 3| ; depth 

 3i. D. 7 ; A. 9 ; Lat. 1. 36 ; 12 scales in a transverse series. Arkansas

 lutrensis and pulchella Girard, Proc. Acad. Nat. Sci. Pliila. 1856, 199, 200 : Leuciscus 

 lutrensis Giiiitlicr, vii, 258.) 



232. C. dcSacBOSa (Grd.) J. & G. 



Body elliptical, moderately compressed. Head shortish, rather blunt, 

 the profile forming an even curve. Mouth moderate, oblique, the max- 

 illary not reaching to the eye. Lateral line somewhat decurved. Eye 

 moderate, 3-1 in head. Scales rather large. Head 4; depth 3|. D. 8; 

 A. 8 j Lat. 1. 33. L. 2i inches. Streams in the Rio Grande region. (Gi- 

 rard.) More than one species may be here included, but, if so, they can- 

 not be recognized from Dr. Girard's descriptions. Of all of Girard's 

 Moniancc the types of only lutrensis and proserpina can now be found.

233. C. aurata (Grd.) J. & G. 



Body subfusiforrn, compressed, little elevated. Caudal peduncle 

 rather slender. Head rather blunt and heavy. Mouth small, oblique, 

 the upper jaw projecting, maxillary not reaching to the eye; upper lip 

 below the level of the pupil. Lateral line little decurved. A dusky 

 streak along sides. Head 3f ; depth 4. D. 8 ; A. 8 j Lat. 1. 37. L. 2

234. C. iormosa (Girard) J. & G. 



Body elliptic, compressed. Head small, rather slender and pointed. 

 Mouth moderate, oblique, the maxillary barely reaching orbit ; upper 

 lip on the level of the pupil. Eye large, 4 in head. Lateral line de- 

 curved. Scales small. Dorsal fin rather high. Head 4; depth 3|. 

 D. 8; A. 9; Lat. 1.49. L. 2| inches. Rio Mimbres, Mexico. (Girard.) 

 If we may trust Girard's figure, this species is well distinguished by the 

 small size of the scales.
