 1878. Sciurus variabilis Alston. P. Z. S. L. p. 665. 



I confirm Alston's statement (1. c. p. 668) that this 

 species has only one upper premolar. Allen (Monogr. of 

 N. A. Rodentia. 1877. p. 672) states in his synopsis that 

 the species in question has two upper premolars. The latter 

 author, 1. c. p.p. 771 and 772, however had a single spe- 

 cimen at his disposition , agreeing in coloration with Wag- 

 ner's Sc. pyrrhonotus , but it being a mounted example, 

 perhaps its skull had been lost, and was a false one, or 

 Allen has been mislead by an incorrect citation. Our se- 

 ven skulls present one upper premolar. 



Habitat. Costa-Rica; Panama; New-Granada; Ecuador; 

 Peru; Chili; Bolivia; W. Brazil; Venezuela.
