XIV. — On Giant Squirrels from the Amazonian Region. 

 By Oldfield Thomas. 



The British Museum has received during the last two or 

 three years a number of Giant Squirrels belonging to the 

 Sciurus Langsdorji 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 

 by the loan of the original type of S. tricolor, Poppig, from 

 Maynas, Peru, without which it would have been impossible 

 to determine to what form that name should be applied. 



Sciurus igniventris, Wagn. 



Nericagua and Munduapo, Upper Orinoco (G. K. Cherrie) ', 

 Bogota {G. D. Child). 



The type locality of this species is Marabitanas, on the 

 Upper 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 Meta, which 

 falls into the Orinoco in the same 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. Goodfellow. 



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

 angle between the Lower lluallaga and the Maranon ; but as 

 Mr. Goodfellow obtained two species on the Coca to the 

 northwards, 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
