XIV. — On Giant Squirrels from the Amazonian Region. 

 By Oldfield Thomas. 



TnK British Museum has received during the last two or 

 three years a number of Giant Squirrels belonging to the 

 Sciurus Lang>tdorJi group from several different localities in 

 South America. On determining these one proves to need 

 description, while additional localities may be recorded for 

 others. 



During the progress of this work Dr. Kiikenthal, of Bres- 

 lau, has been good enough to render me valuable assistance

 Bogota (G. Ik Child). 



The type locality of this species is Marabitanas, on the 

 UppfT Rio Negro, not far from the latter river's junction with 

 the Upper Orinoco. The further extension of the species 

 westwards to Bogota follows the line of the Rio Mcta, which 

 falls into the (Jrinoco in the s-ame district that Mr. Cherrie 

 collected in. South-eastwards the species ranges along the 

 Rio Negro to its mouth. 



Sciurus tricolor, Poppig. 



Mouth of Rio Coca, Upper Rio Negro. Collected and 

 presented by Mr. W. Goodtellow. 



The type locality of Poppig's species was Maynas, in the 

 angle between the Lower lluallaga and Hie Maranon ; but as 

 Mr. Goodfellow obtained two species on the Coca to the 

 n<'rthwards, and a third had been found by Signor Balzan to 

 the southwards, I was in great difficulty as to which was the 

 real S. tricolor. Happily Dr. Kiikenthal's kindness has
