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 ow'n 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. Maram. Califomian Sąuirrel. 



Dr. Bachman's acąuaintance 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 follovving description. 



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

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

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

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

 and very bushy. Hairs of the tail black. t\vice annulated \vith dirty 

 yellow, and broadly tipped with w'hite — the white very conspicuous 

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

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

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

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

 first vvith yellow, then black, and then \vhite. Whiskers black, 

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

 an orange colour as the upper.
