Upperparts finely grizzled dull buffy and black, giving an olivaceous 
effect; hairs blackish at base, narrowly annulated near the tip with yellow- 
ish and black and tipped with pale yellowish; underparts with the chin and 
throat white, the chest and belly ochraceous buff, varying in intensity in 
different specimens, often with a narrow white median line, and the inguinal 
and scrotal areas whitish; limbs externally like the upperparts; internally 
the fore limbs are whitish, the hind limbs fulvous; tail long and narrow, the’ 
hairs broadly ringed with black and yellow, the tips pale yellow or whitish, 
the general effect being a coarse grizzle of black and pale yellow on both 
surfaces; ears rather narrow and pointed, thinly clothed with short fulvous 
or pale rufous hairs.!

Specimens examined, 50.— Brazil: Southern Minas Geraes, Parand, and 
Sao Paulo (Robert), 26 (Br. Mus.); Espirito Santo, 1 (Nat. Mus.); Roga 
Novo, Serro do Mar, Parana, 1 (Field Mus.); Santa Rita, Bahia, 1 (Mus. 
Comp. Zoél.); Cantogallo, and other points near city of Rio de Janeiro, 15

1'Three specimens from Alambary (Victoria), Sao Paulo, differ from all the others in 
presenting the peculiar reddish tone of specimens made up from alcoholic material, and the 
condition of the feet also indicates that this has been the case. 
2 This is the alcoholic series referred by me in 1877 (Mon. N. A. Rodentia, pp. 757, 761, 
762) to Sciurus estuans var. estuans, of which measurements are given on DP. 761, and on 
which my description of var.’ e@stuans was based. These specimens have been reéxamined 
in the present connection.
