SCIURIDAE. 



6. Sciurus yucatanicus (Allen). 



A single female was taken, and Mr. Cole notes that but few others were 

 seen, in contrast to Mr. F. M. Chapman's experience in 1896, who found them 

 "common at Chichen-Itza."

A single specimen from Chichen-Itza was preserved.

 in the fields were preserved. 



GEOMYIDAE. 



10. Heterogeomys torridus Merriam. 



A skin and skull in the collection, from Xbac, southeast of Izamal, seem 

 referable to this species, though more specimens might show that the peninsular 

 animal is distinct from those of Mexico proper. The specimen was obtained 

 in 1901 by Dr. George F. Gaumer's collector.
