c. * Ursus americanus eremicus Merriam. 



Ursus americanus eremicus Merr., Proc. Biol. Soc. Wash., xvii, 

 1904, p. 154. 



*Dr. Merriam compares this type specimen with Ursus amblyceps Baird. 

 As I have already shown, Pub. Field Columb. Mus., in, 1903, p. 235, Zool. 

 Ser., this name of Baird's, as it represents no characters whatever, is a nomen 

 nudum, and cannot be used. Baird had only a flat skin of a cinnamon bear, 

 and no skull, and was unable to give any recognizable description.
