 By IlKRnEUT C. Ronixsox and C. Boden Kloss. 



In this paper are described most of tlie 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 ^Tekong River in 1920, and 

 two races of squirrels obtained at earlier dates in Siam 

 and Cambodia. 



1. Tupaia giis cochinchinensis, subsp. n. 



Rather smaller tlian T. y. concolor, Bonhote, of South 

 Annam, browner and less olivaceous, being much more 

 richly coloured — the buff element iu the pelage of concolor 

 being everywhere replaced by deep ochraceous buff (almost 

 ochraceous orange). 



Darker and more richly coloured also than T.g.cambodiana, 

 Kloss, from the coast of Cambodia, which is olivaceous ou 

 the shoulders with a buffy neck-stripe and less rusty on the 

 rump. MaraniBe 3 — 3 — 6, as in both the others. 



T. g. cochinchinensis is at times profusely blackened on 

 the posterior back, as also is T. g. concolor. 



Type. — Adult female (skin and skull) collected at Traug- 

 bom, 30 miles east of Saigon, Cochin China, ou 1st 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 antiamensis, subsp. n. 



Like T. d. dissimilis (Ellis, in Grey) of Pulo Coudore off 

 the south-east coast of Cochin China, but the whitish ocular 

 borders and neck-stripes more distinct ; as a scries less 

 suffused with rusty above and on the tails, which are also 

 distinctly darker beneath, i. e., blacker. 



Upper parts a grizzle of black and buff, darkest on the 

 head and suffused with ochraceous tawny on the rump : feet 

 finely grizzled black and buff. 



Under parts and inner sides of limbs buff to cream-colour. 

 Tail coarsely aunulated buff and black, the latter in excess; 

 the lower median line dull buffv. Mamnue 3 — 3 = 6.
