New Mammals from French Indo-China and Siam, 87 
V.—New Mammals from French Indo-China and Siam. 
By Hersert €. Rosryson and C. Bopun Kross. 
In this paper are described most of the new forms obtained 
by one of us during a visit to South Annam and 
Cochin China in 1918, others secured by our collector 
during a journey down the Mekong River in 1920, and 
two races of squirrels obtained at earlier dates in Siam 
and Cambodia. 
1. Tupaia glis cochinchinensis, subsp. n. 
Rather smaller than 7. g. concolor, Bonhote, of South 
Annam, browner and less olivaceous, being much more 
richly coloured—the buff element in the pelage of concolor 
being everywhere replaced by deep ochraceous buff (almost 
ochraceous orange). 
Darker and more richly coloured also than 7. g.cambodiana, 
Kloss, from the coast of Cambodia, which is olivaceous on 
the shoulders with a buffy neck-stripe and less rusty on the 
rump. Mammze 8—3=6, as in both the others. 
T. g. cochinchinensis is at times profusely blackened on 
the posterior back, as also is 7. g. concolor. 
Type.—Adult female (skin and skull) collected at Trang- 
bom, 30 miles east of Saigon, Cochin China, on Ist June, 
1918, by C. Boden Kloss. No. 3622/CBK. 
Specimens examined.—Five from the type-locality compared 
with ten examples of concolor and seven of cambodiana. 
For measurements see table on p. 89. 
2. Tupaia dissimilis annamensis, subsp. n. 
Like 7. d. dissimilis (Ellis, in Grey) of Pulo Condore off 
the south-east coast of Cochin China, but the whitish ocular 
borders and neck-stripes more distinct; as a series less 
suffused with rusty above and on the tails, which are also 
distinctly darker beneath, i. e., blacker. 
Upper parts a grizale of black and buff, darkest on the 
head and suffused with ochraceous tawny on the rump: feet 
2 
finely grizzled black and buff. 
Under parts and inner sides of limbs buff to cream-colour. 
Tail coarsely annulated buff and black, the latter in excess ; 
the lower median line dull buffy. Mammz 3—3=6.
