COL. ABERT’S SQUIRREL 
263 
HABITS. 
Dr. Woodhouse, from whose description we have extracted above, 
makes the following remarks : “ This beautiful squirrel I procured whilst 
attached to the expedition under command of Capt. L. Sitgreaves, 
Topographical Engineer U. S. Army, exploring the Zuni and the great 
and little Colorado rivers of the west, in the month of October, 1851, in 
the San Francisco Mountain, New Mexico, where I found it quite 
abundant, after leaving which, I did not see it again.’’ 
geographical distribution. 
So far as shown by the foregoing account, and according to our know- 
ledge, this squirrel has not been seen except in the San Francisco Moun- 
tain, New Mexico. It is, however, most likely that it inhabits a con- 
siderable district of elevated and wooded country in that part of our 
Continent, and may hereafter be found in California or even Oregon. 
GENERAL REMARKS. 
We have not been able to procure any further information regarding 
this species, which was first named Sciurus dorsalis by its discoverer, but 
a subsequent examination having satisfied him that this name had “ al- 
ready been applied by J, E. Gray, to one of the same genus,” he proposed 
“ to call it Sciurus Jlberti, after Col. J. J. Abert, chief of the corps of 
Topographical Engineers, U. S. Army, to whose exertions science is much 
indebted.”— (Proceed. Acad. Nat. Sci., Phil., Dec. 1852, p. 220. 
It gives us great pleasure to welcome this beautiful new animal under 
the name of Col. Abert’s Squirrel,
