ADDENDA — 30. CATOSTOMIDiE CATOSTOMUS. 883 



from which it is evident that the species intended was the Catostomus 

 hubahis of Kirtland — the BuhaUchthys alius of this work (p. 110). If 

 this identification be accepted in our nomenclature, the specific name 

 huhalus should take the place of altuSy and cyprinella that of hubalus. 

 If Eafinesque's species be considered unidentifiable, the same change 

 should be made, as Kirtland's use of the name huhalus followed next. 

 As Eafinesque's I. huhalus was the type of his Ictiohus, in strictness the 

 name BuhaUchthys should be superseded by Ictiohus as a subgeneric 

 name, while the group heretofore called Ictiohus would be called Scle- 

 rognathns C. & V. 



Ill this view, the species should stand as follows: 



113. I. cyprinella (C. & V.) Ag. (Sderognathns.) 



114. I. MJ-US (Ag.) J. & G. {Tctiohus.) 



115. I. bubalus Raf. {Ictiol)ns.) 



116. I. cai'pio (Raf.) Nels. (Carpiodes.) 



117. B. damalis* (Grd.) J. & G. (Carpiodes.) 



118. I. tlionipsoni (Ag.) Nels. (Carpiodes.) 



1 19. 1. bison (Ag.) Nels. (Carpiodes.) 



120. 1. cyprinus (Le S.) J. & G. (Carpiodes.) 



121. I. difforniis (Cope) Nels. (Carpiodes.) 



Of these species, 117, 118, 119, and 121 are of doubtful validity. 



Page 126. The following species of Catostomus may be added: 

 130 (c). C nebnlifcr G:irman. 



Brownish, clouded and blotched with darker; a blackish lateral 

 shade; belly pale; lower half of preopercle abruptly silvery. Body 

 stout, little compressed. Head nearly as broad as eye; eye small, 

 about half snout; mouth small; lips with considerable free margin. 

 Dorsal inserted midway between snout and caudal; caudal deeply 

 notched; anterior rays of dorsal longest. Head 5; depths. D. 9; 

 A. 8; scales 14-90-14. Nazas River, Coahuila. {Garman.) Very close 

 to G. guzmaniensis, if not the same. 



(Catostomus vehulifcrus Garman, Bull. Mus. Comp. Zoiil. viii, 89, 1881.) 



* It is better not to adopt the name tumidus for any species of Carpiodes, as the 

 original Carpiodes tumUhis is not certainly identified. Tlie description agrees well 

 with yontig specimens of /. hnhaJus, a species lately obtained by ns in Texas.
