28 JOURNAL, BOMBAY NATURAL HIST. SOCIETY, Vol. XXIII. 



light wood-brown, a prominent patch on sides of cheek and neck 

 greyish white. Muzzle more greyish white than brown. Under- 

 snrface nearly wholty pnre white, a few hairs only on the sides of 

 the belly with slaty bases. 



Hands and feet only brown at the base, and on the middle line, the 

 sides and the whole of the digits whiter — in true lihayrei the feet are 

 wholly brown with the exception of a few hairs at the root of the 

 claws. Tail drabby basally, darkening to blackish brown at the tip, 

 the darkening less rapid and less intense than in i^hayrei. 



Bimensions of the type (measured in the flesh). — Head and body 

 148; tail 128; hindfoot 30-5; ear 23. Skull, greatest length 

 39- 3 ; condylo-incisive length 35 ; zygomatic breadth 24*2 ; nasals 

 10-2 ; palatilar length 17*2 ; p* and three molars 7*8. 



y^/^e._Adult male. B.M. No. 14.4.3.2. Original number 3601. 

 Collected on Mt.Popa at about 3,000', 7th September 1913, by G. 0. 

 Shortridge, and presented by the Bombay Natural History Society. 



This form, distinguished by its nearl}^ wholly white feet, is of 

 about the same size as true ijhayrei. On the other hand the Siamese 

 representative of i^haijrei is larger, though on account of its general 

 identity in colour and other characters I should still call it the same 

 species. 



SCIUROPTEEUS PHAYEEI LAOTUM, Subsp. n. 



Larger than 'phayreA and frobus. 



Coloration about as in p^ohus, though the undersurface tends to 

 be more largely mixed with slaty, and the white itself is less pure. 

 Hands and feet brown with white digits. 



Dimensions of the type (measured on the skin). — Hindfoot, 34 

 mm. 



Skull, greatest length 42 ; condylo-incisive length 38-3; zygo- 

 matic breadth 16-2; nasals 10-5 x 6-6 ; palatilar length 19 ; p* and 

 three molars 7-3 (worn and crushed together, 8-9 in one of Mr. Lyle's 

 specimens.) 



Habitat. — Laos Mts. and Siam. 



T^pe.— Adult female. B. M. No. 62.8.16.3. Collected by 

 Moiihot. 



Mr. Lyle obtained four examples of this flying squirrel in North- 

 ern Siam, but unfortunately two of their skulls are lost, one .is 

 broken, and the fourth shows signs of having been in captivity. 

 I have therefore had to select Mr. Mouhot's specimen as the tj^e. 



All the specimens agree in the greater length of the hindfoot as 

 compared with pliayrei and prohus. 



The third small Flying Squirrel in the collection is Sciuropterus 

 spadiceus, Blyth, represented hj a single specimen from Maymyo 

 near Mandalay, presented by Mr. G. B. H. Fell.
