PRESBYTIS CATEMANA, new species. 
1902. Semnopithecus sumatranus, Mintuer, Proc. Acad. Nat. Sci. Philadel- 
. phia, p. 159, March, 1902, issued June 11, 1902. (Indragiri River speci- 
mens. ) 
1906. Presbytis cana MiLiER, Proc. U. S. Nat. Mus., XXXI, p. 275, Septem- 
ber 11, 1906. (Kateman River specimens. ) 
Type.—Skin and skull of adult female, Cat. No. 123149, U.S.N.M., 
collected along the Kateman River, eastern Sumatra, August 23, 19038, 
by Dr. W. L. Abbott. Original number 2762. 
Diagnostic characters ——A member of the Presbytis sumatrana 
chrysomelas group, differing from typical swmatrana in being gener- 
ally brown where suwmgtrana is black, in having conspicuous gray 
spots on the thighs, and less white on the under side of the tail than 
has sumatrana. It is closely related to P. cana Miller, but differs in 
having less conspicuous thigh patches. 
Color.—Type: Upper parts of body, base of tail above, and outer 
side of arms, drab; hands and feet and terminal portion of tail, black- 
ish brown, probably nearest a very dark sepia of Ridgway; hairs of 
head blackish, but with their bases dirty white; entire under parts, 
including chin, throat, inner side of arms to wrists, and inner side of 
legs to ankles, whitish. The whitish color becoming gray extends al- 
most completely around the upper part of the thighs, leaving only a 
narrow drab band on the outer side, making a mark similar to, but 
less conspicuous, than that on Presbytis cana Miller. Under side of 
tail for basal third a very light broccoli brown. Series: The four 
specimens of this species are very uniform in color, showing no essen- 
tial variations. Cat. No. 113175, U.S.N.M., from the Indragiri River 
has the thigh patches somewhat darker than they are in the other 
three skins. 
Skull and teeth.—These show no distinguishing characteristics. 
Measurements.—See table, page 673. 
Specimens examined.—Your, two adult females from the Kateman 
River and two adult males from the Indragiri River. 
Remarks.—While Presbytis catemana 1s sufficiently distinct from 
the related forms on Sumatra its resemblance to P. cana Miller, from 
the off-lying Pulo Kundur, is very close, the only essential difference 
being that the Kundur animal has the light area of the thigh larger 
and whiter than has the Sumatran form, differences which were 
pointed out by Mr. Miller in his description of P. cana.“
