 white. The sides of the face and neck, the whole of the inner side 

 of the limbs, feet, and the whole of the under parts, of a deep golden

 golden hue as the sides of the face ; hairs of the feet are mostly 

 blackish at the root, and some are obscurely tipped with black ; 

 hairs of the tail black at the roots, and the remaining portion of a 

 bright rusty yellow ; each hair three times in its length annulated

Of this species Dr. Bachman remarks, that although he has seen 

 many specimens labelled under the above name, yet the only true 

 S. macrourus which has come under his own observation, is one in the 

 Philadelphia Museum. Not being in possession of his own memo- 

 randa upon this species, he quotes the description published by Say. 



Sciurus aureogaster, F.Cuv. et Geoff. Mamm. Califomian Squirrel. 



Dr. Bachman's acquaintance with this species rests upon the ex- 

 amination of some specimens in the Museum of the Zoological So- 

 ciety, from which he draws up the following description. 



The general hue above is deep gray, grizzled with yellow : the 

 under parts and inner side of the limbs are deep rusty red ; chin, 

 throat, and cheeks, pale gray. Limbs externally, and feet, coloured 

 as the body above. Hairs on the toes chiefly dirty white. Tail large 

 and very bushy. Hairs of the tail black, twice annulated with dirty 

 yellow, and broadly tipped with white — the white very conspicuous 

 where the hairs are in their natural position. Ears thickly clothed, 

 chiefly with blackish hairs, the hinder basal part, externally, with 

 long white hairs extending slightly on the neck. All the hairs of 

 the body are gray at the base, those of the upper parts annulated 

 first with yellow, then black, and then white. Whiskers black, 

 the hairs very long and bristly. The under incisors almost as deep 

 an orange colour as the upper. 



Habitat Mexico and California.
