MONOC.KAPriS OF XOIITII AMERICAN HODENTIA. 



Audubon and Bachman's figure of (heir Sciurus ferruglniventris 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 douhtless referable Dr. Gray's Macroxus mono, 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 Sciurus 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. aureogastcr of F. Cuvier.
