Carpiodes velifer (Rafinesque). V. 



Only ;i few specimens were obtained, from a deep pool which was connected with the creek only 

 during flood season. 

 Catostomus griseus (( iirard ). B, V. 

 Catostonius commersonii (Lacepede). B, V. 

 Campostoma anomalum (Rafinesque). 11, V. 

 Chrosomus erythrog-aster Rafinesque. B, V. 



This species had not previously been noted so far west. Jordan and Evermann (Bull 

 Nat. Mus., p. 209) give Iowa as the western limit of its range. 

 Hybognathus nuchalis Agassiz. 1!, V. 



These specimens have a dark lateral band. 

 Pimephales promelas Rafinesque. V. 



Only one specimen obtained.

 Leuciscus evermanni Juday, new species. 



Among the specimens obtained from Boulder Creek, three were found which belong to 

 Leuciscus, but which apparently represent a new species, a description of which is given be 

 specimens were not examined until after they had been in preserving fluid for some time,

efforts to obtain more were unsuccessful: consequently, life colors can not be given. Unfortunately, too, 

 the largest speci n. which was intended for the type, was misplaced before the description was com- 

 pleted and lias not since been found, so that the- sec 1 in size is here described as the type. Some 



notes on tin- largest one had been made, however, and these are given in the table. It is a very great 

 pleasure to me to name the species for Dr. Barton Warren Evermann, of the Bureau of Fisheries.
