SQUIRRELS OF MEXICO AND CENTRAL AMERICA 67 



the way south from that port we took the last typical specimen of S. s. 

 cocos at Jamiltepec, Oaxaca ; the series taken beyond, at Puerto 

 Angel, is intermediate between true socialis and cocos. We found 

 these squirrels frequenting cocoanut groves near Acapulco and feeding 

 upon the nuts. It is the only squirrel we saw doing this although 

 cocoanut trees are common in the ranges of various other species. 

 The name of the subspecies was suggested by this peculiar habit. 



Specimens exa?nhzed. — Thirty-three : from Acapulco, Aguacatillo, 

 San Marcos, and Ometepec, Guerrero ; Pinotepa, Llano Grande and 

 Jamiltepec, Oaxaca.
