ADDENDA 30. CATOSTOMIDvE CATOSTOMUS. 883 



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

 bubalus of Kirtland the Bubaliclitliys altus of this work (p. 110). If 

 this identification be accepted in our nomenclature, the specific name 







hubalus should take the place of alt-us, and cyprinella that of bubalu*. 

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

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

 As Bafinesque's J. bubalus was the type of his Ictiobus, in strictness the 

 name Bnbalichthys should be superseded by Ictiobus as a subgeueric 

 name, while the group heretofore called Ictiobus \vould be called Sclc- 

 ronnathus 0. & V. 



In this view, the species should stand as follows: 



113. I. cypriaiella (C. & V.)Ag. (Sclerognatlitt-s.) 

 III. I. HB-us (Ag.) J. & G. (Ictiobus.) 



115. I. ImbaBiis Raf. (Ictiobus.) 



116. I. Ciirpio (Raf.) Nels. C Carpi-odes. ) 



117. 1. damalis* (Grcl.) J. &. G. (Carpiodes.) 

 IIS. I. thoiaipsoui (Ag.) Nels. (Carpiodes.) 



119. 1. bisoDi (Ag.) Nels. (Carpiodes.} 



120. I. cyprintis (Le S.) J. & G. (Carpiodes.) 



121. I. c&gflfoi'iilis (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: 

 13O (c). C. nebulafer Garman. 



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; depth 5. D. 9; 

 A. 8; scales 14-90-14. Nazas Eiver, Coahuila. (Garman.) Very close 

 to C. guzmaniensis, if not the same. 



(Catostomus tiebuliferus Garman, Bull. Mus. Comp. Zool. viii, 89, 1881.) 



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

 original Carpiodes tumidus is not certainly identified. The description agrees well 

 with yonug specimens of I. bubalus, a species lately obtained by us in Texas.
