CATOSTOMUS LONGIROSTRIS.

gave to this species tbe name of mtrora, iu allusion to the red breeding 

 colors of tbe male. Western specimens weie still later described by 

 Girard as two distinct species, griseus and lactarhis, ai^pareutly witbout 

 comparison with tbe Eastern forms. 



Tbe examination of tbe large series of specimens noticed below, to- 

 getber witb otbers from tbe Great Lakes and Upper Mississii)pi, bas 

 convinced me tbat all belong to one species, variable to some degree, 

 but not more so tban is Catostomns teres and less so tban Erimyzon 

 sucetta. Some of tbe Upper Missouri specimens referable to G. grisetis 

 Grd. have on an average rather smaller scales (95 in the lateral line 

 instead of 100 to 110) ; but I am unable to distinguish a tangible variery, 

 Tbe original types of C. lactarhis Girard are not now to be found, but 

 tbe description indicates no difference from C. longirostris.
