 Note on the type of Colymlms : — 



The genus Colymhvs as used by Linnseus in 

 1758 contained four species: a?-ci/t;u5 (Black-throated 

 Diver), cristatvs (Great Crested Grebe), auritus 

 (Slavonian Grebe), and podiceps (American Pied- 

 billed Grebe). Latham introduced Podiceps for the 

 Grebes and retained Coli/mhus for the Divers, and 

 his usage was followed by practically every other 

 author until the year 1882, when Dr. Stejneger 

 proposed to use Colymhus for the Grebes.
