Tbis is iiiiotlicr of our nunierous species wliidi liave ;m e.xtretiiely wide 

 range of distribution and a considerable range of variation. It has l)een

 ^iven was tliat of catostomns, which, however, had to be set aside when 

 the generic nanie Catotstomus was i)roj)oscd for it. The next name in 

 order of time is the very appropriate one ol loiitjirostntm Le Sueur (more 

 properly spelletl longhostris), given to some specimens from Vermont. 

 I'ive pages later, the name hudsonius was given as a substitute for ca- 

 toatnmus of Forster. The slight priority of longirostrum over hudsonius, 

 however, seen)s to entitle it to pn'feience, although the lattei- name has

 to be identical with hiulnoHius received from Kichardson the name ^^/or-

 reason, transferred from this species to (ercn by Professor Agassiz, who
