116. Sciurus griseimanus M.-Edw. The Grey-footed Squirrel. 



Kidley (J. S. B. R. A. S. no. 25, Jan. 1894, p. 59), in a " List of 

 Mammals recorded from Pahang," includes " Sciurus griseimanus, 

 A. M.-Ed\vards," but unfortunately gives no details about it. 



Distribution. Cochinchina, Carnbodia, Upper Burma (Blanf.Faun. 

 Ind., Mamm. p. 381), Laos (O. Thomas, P. Z. S. 18S6, p. 68), and 

 Malay Peninsula? 



N.B. — Sciurus atridorsalis G-ray. The Black-backed Squirrel. 



Sciurus atridorsalis, Blanf. Faun. Ind., Mamm. p. 382. 



O. Thomas (P. Z. S. 1886, p. 76) records a single specimen from 

 Klang collected by Davison, but says : — " There is possibly some 

 mistake in the labelling of this specimen, as the species is not 

 otherwise known to occur south of Tavoy, Tenasserim, and the 

 specimen exactly matches some of Mr. Davison's Moulmein skins." 



Davison (J. S. B. B. A. S. no. 20, 1889, p. 84) says he " obtained 

 one specimen of the common squirrel Sciurus atrodorsalis " on Pulo 

 Tioman in August 1889 ! 



Distribution. Burma. 



117. Sciurus macclellandi Horsfield. The Striped Himalayan 

 Squirrel. 



Sciurus macclellandi, Blanf. Faun. Ind., Mamm. p. 386. 



In the Museum at Taiping, Perak, there is a stuffed specimen 

 of S. macclellandi barbei from Taiping (it is labelled S. tenuis 

 Horsf.). 



In the Siamese Museum there are two specimens, also of the 

 barbei race, from Pefchaburi, Siam. 



I obtained a single individual in a tree in a wood near Bortong 

 Kabin, 26th March, 1897. 



Distribution. Sikhim, Eastern Himalayas, Assam, Cachar, 

 Manipur, China, Formosa, Cochinchina, Siam, Tenasserim, Malay 

 Peninsula (Perak, Malacca). 



N.B.— Mr. J. L. Bonhote (A. M. N. H. ser. 7, vol. v. p. 53, 

 1900) distinguishes specimens from Perak as Sciurus macclellandi 

 leucotis (Temm.), differing from S. barbei in having the light 

 stripes narrow and hair of ear white at base. 



118. Sciurus tenuis Horsfield. The Slender Squirrel. 

 Sciurus tenuis, Cantor, p. 42. 



Cantor records this species from Singapore and the Peninsula, 

 and apparently found it rare, only observing two individuals. 

 Horsfield (Cat. Mamm. Mus. East India Co. 1851, p. 154) 

 mentions a specimen from Singapore, collected by Finlayson. 



O. Thomas (P. Z. S. 1886, p. 76) records eleven specimens from 

 the Malay Peninsula ; they are from Klang and Ulu Langhat in 

 Selangor, from Malacca, from Gunong Pulai in Johore, and from 

 Singapore, and says " these specimens are all very similar, and 

 precisely agree with Horsfield's type."
