T52 MONOGRAPHS OF NORTH AMERICAN RODENTIA. 
Audubon and Bachman’s figure of their Sciurus ferruginiventris is also 
an excellent representation of the average phase of this species, to which their 
description is unequivocally applicable. The locality of “California” is 
undoubtedly erroneous. As Professor Baird has remarked, the species of 
Squirrels described by these authors as ‘‘probably from California”, nearly all 
came from Mexico or from points far south of the present State of California. 
To this species is doubtless referable Dr. Gray’s Macroxus morio, from 
an unknown locality. 
The specimens in the collection are mostly from the provinces of Vera 
Cruz and Oaxaca in Southeastern Mexico ; one, however, is from Guatemala. 
On one of the labels is written, probably by the collector, Professor Sumi- 
chrast,—‘‘ The common species of Sciwrus of the tierra calienta of the east 
coast.” Dr. Gray also cites examples from Colombia, which, he says, were 
received from Parzudaki and Verreaux, as the S. awreogaster of F. Cuvier.
