U. 8. P. R. R. EXP. AND SURVEYS ZOOLOGY GENERAL REPORT. 



This animal was first described by Dr. S. L. Mitchell, as the thirteen-lined or federation 

 squirrel, on account of the thirteen lines of stars and stripes which he fancied he detected in its 

 markings. It is, however, but rarely that this number can be fully made out. 



Sabine, a year after, published the same species under a different name, which, of course, 

 becomes reduced to a synonym.
