Nine specimens from the mainland of Sumatra. For localities and 
measurements see table below. Examples from higher up the coast, 
as those opposite Pulo Rupat, average slightly darker than those 
taken farther down, the Indragiri-Kateman specimens. The insular 
race described below can not be considered a highly differentiated 
form. The fact, however, that the thirty-two squirrels of this 
eroup from the lowlands and adjacent islands of eastern Sumatra 
can be arranged in two fairly well-marked series according to in- 
tensity of color, one from the mainland the other from the islands, 
shows the necessity of recognizing another race of this highly variable 
group of squirrels. 
SCIURUS VITTATUS RUPATIUS, new subspecies. 
Type.—Adult female, skin and skull, Cat. No. 148406, U.S.N.M., 
collected on Pulo Rupat, east coast of Sumatra, March 17, 1906, by 
Dr. W. L. Abbott. Original number 4733.
