known species, the tail being about three inches longer than the body, — a 

 proportion found in no other Mexican Squirrel. The general size, as well as 

 the narrowness of the tail, gives further evidence of its correct reference 

 being lierc. There are, furthermore, two specimens in the collection that 

 aji^rce fully witli Bennett's description, which I have no hesitation in referring 

 to this species. 



The Sciurus variegatoules of Ogilby and the Sciurus griscocaudutus of 

 Gray, from the "west const of South America", I am convinced arc both 

 referable to this. species, and hence also Gray's "var. 1" of Gray's Macroxux 

 colticei They agree closely with the specimens from Panama and La Union. 



The Sciurus varius and S. socinlis of Wngner were referred by Wiegmann 

 to this species, as I think, incorrectly. The former seems to more nearly 

 agree witii 8. boothia, while the latter I am unable to identify. 



Tiiis seems to be a common species in Southern Mexico and Central 

 America southward to Ecuador, and presents, as noted above, widely varying 

 phases of coloration. 



In several specimens of this species, in which the dentition could be 

 examined, there were generally found two upper premolars, but two out of 

 four alcoholic examples hud only one.
