 Catostomus clarkii Jordan & Copeland, Check List, 156, 1876. 



Habitat. — Elo Santa Cruz in Arizona. 



Notbiug is known of this species except from the figure given by 

 Girard and the descriptions published by Baird and Girard. The 

 original types of the species are not to be found in the Museum, and 

 there are no specimens of recent collection which appear to belong to 

 it. It seems, however, to be a valid species, related to G. insignis. 

 Its lips have not been figured, hence I can only infer that it belongs to 

 the group with a narrow upper lip.

 Catostomus insignis Jordan «fe Copeland, Check List, 156, 1876. 



Habitat. — Tributaries of the Eio Gila. 



The original types of this species, from the Eio San Pedro, are now 

 lost. The specimens collected by Dr. Rothrock in Ash Creek, Arizona, 

 and referred to this species by Professor Cope, undoubtedly belong 

 here. The species is a well-marked one, both as to form and coloration. 

 The genus Minomus, of which it was made the type, appears, however, 

 to have no tangible existence.
