1858. Charles Girard. Report upon the Fishes collected by the various Pacific Railroad Explorations 
and Surveys. Vol. x, part iv, 1-400, with numerous plates. 
But little collecting in the Colorado Basin was done by the parties connected with 
the Pacific railroad surveys. The records mention only three species from this basin. 
All of these were collected in the Zuiii Eiver in 1852 by Dr. S. W. Woodhouse, under 
Capt. L. Sitgreaves. Specimens of one of the species {Gila elegam) were obtained in 
the Gila in 1853 by Dr. A. L. Heermann, under Lieut. J. G. Parke; in the Colorado 
Eiver in 1851 by Arthur Schott, under Maj. Emory; and at Fort Yuma in 1855 by 
* In this paper Gatostomus pleheius (Vantosteus plebeiua) and Gila pulchella {Leuciscus nigrescens) are credited to the 
“Eio Mimbres, tributary of tlie Ilio Gila.” But the Bio Mimbres is not a tributary of the Gila, but of Lake Guzman, in 
Chihuahua, and these two species are not known to occur in the Colorado Basin.
