150. BuhalicUhys cyanellus (Nelson) Jordan. Small-mouthed Buf- 

 falo. (^Buhalichthi/s bubalimis and BubaKchthi/s alius. M. V. 325 ; 

 Ichthyohus cyanellus Nelson 49.) 



Abundant in all the larger streams throughout the state. An 

 examination of Mr. Nelson's typical specimens shows that they 

 are the young of the common Buhalichthys huhalus of Agassiz. 

 As the specific name ^^buhalus'^ is hardly tenable for this species, 

 if we conceive that the huhalus of Rafinesque is an Ichthyohus, I 

 have lately suggested the name hubalinus as a substitute. Cya- 

 nellus has however priority over buhalinus. I therefore propose to 

 adopt Mr. Nelson's name for this species.
