1876. Prof. E. D. Cope axd Dr. H. C. Yarrow. Eeport upon the Collections of Fishes made in 
X>ortions of Nevada, Utah, California, Colorado, New Me-xico, and Arizona, during the years 
1871, 1872, 1873, and 1874. <^Zoology of the Wheeler Survey west of the 100th meridian,

This is by far the most important contribution to the literature of the ichthyology 
of the Colorado Basin that has yet appeared. The authors credit no fewer than 27 
species to this basin. 
In the body of the report 29 nominal species are recorded from Colorado Basin 
localities, but 4 of these were apparently erroneously so referred. They are Oila mon- 
tana from ‘‘Arizona,” Qlla pandora from “Pagosa, Colo.,” Oila gula from “Eio de 
Acama” and “near Fort Wingate, Mex.,” and PtijcJiostomus congestus froin “Ash 
Creek, Ariz.” Gila montana, {=LeuciscMS hydrophlox) was probably from some place 
in the Utah Basin. Both Oila pandora and Oila gula are now regarded as being 
identical with Leuciscus nigrescens, a Eio Grande si>ecies, and Cope & Yarrow’s 
specimens probably came from that basin. Ptychostomus congestus {Moxostoma con- 
gestnm) is a Texan species, and the 3 specimens which Cope & Yarrow provisionally 
referred to this species may have come from some Texan locality. 
In the recapitulation of species (p. 699) the authors name 27 species in the Colo- 
rado Elver list, 4 of which are not given in the body of the report, viz: Ceratichthys 
scpuimilentus {Gouesius sepiamilentus)^ Pantosteus hardus {Pantosteus delpthinus), Pantos- 
tens delphinus, and Goregonus tvilliamsoni. All of these are xiroperly credited to the 
Colorado Basin, as had previously been determined by Prof. Cope.

the Great Basin of the Territory of Utah, in 1859, 385-431. 
Ill this report Platygohio communis { Platygohio gracilis) is credited to Green Eiver, 
Utah, probably erroneously. Potamocottus pnnctulatus is described from a “single 
specimen obtained by Dr. George Suckley, in the summer of 1859, between Bridger’s 
Pass and Fort Bridger.”
