"Colorado and New Rivers." Dr. J. L. Le Conte. In locating this 

 interesting dried example, it is now possible to give its correct 

 place among the catostomoids after fifty-two years of oblivion 

 and erroneous identification. It is unquestionably identical with 

 Catostomus cypho Lockington, which was also described in these 

 Proceedings twenty years later/^ and Lockington's specific name 

 is the one adopted by all writers, as it was thought to have been the 

 first ever given to this peculiar fish. Jordan says^'^ "Catostomus 

 texanus Abbott is less clear [than Catostomus chloropteron Abbott], 

 but what there is of specific characterization in the description 

 points to C. teres. The dorsal carination is frequently observed 

 in stuffed fishes in which some flesh is left in the back to shrink in 

 drying, leaving the back 'carinated.'" These entirely erroneous 

 suggestions were made, of course, shortly before the species was 

 supposed to have been discovered by Lockington. Still further 

 confusion is added bj' its inclusion as a synonym of Moxostoma 

 congestum (Baird and Girard) by Jordan and Evermann.'^ The 

 specific name texanus is unfortunate, as the species is not known 

 from Texas. It appears to have been given under the impression 

 that the Colorado River of that State was intended, together with 

 the New River being likely confused with the Neuces River?. 



Besides the above example is another specimen from the Hardy 

 River in Lower CaHfornia, secured by Mr. S. N; Rhoads in February 

 of 1905. It is important as showing to what extent variation 

 may reach in the species. It has 86 scales in the lateral line to the 

 caudal base, and 5 more on the latter. The type shows 73 scales 

 in the lateral line to the caudal base and 4 more on the latter. As 

 both are adult examples, it would appear hardly likely that Xyrauchen 

 uncomphagre Jordan and Evermann is a distinct species, as it is 

 said to have but 81 scales, with other characters apparently varietal 

 or due to age.
