These tvvo eastern subspecies differ from tiie other forms 

 by tlieir darker colour and tendency to be blackish or dark 

 greyish on the rump. From each other they differ very 

 much as do chinensis and belangeri, and, in fact, they may be 

 looked upon as eastern representatives of these subspecies 

 respectively, ynnalis of the olive-grey chinensis and laotuni 

 of the more lulvous belanyeri, each pair being in about the 

 same latiiu le. 



As Dr, Lyon has carefully recorded where the types of all the 

 various forms of the Tupaiida; are preserved, I may take this 

 oppoitunify of mentioning that the typical specimens of Tupaia 

 laceniata wilkinsoni, ohscura, and longicanda, and 1\ ferru-, 

 ginea jyenaufjensis, described by Messrs. Robins )n and Kloss, 

 and hitherto in Selangor, have now been transferred to the 

 British Museum, in accordance with the enliglitened policy 

 pursued by the authorities of the Federated Malay fcJtates 

 Museum in regard to the preservation of types. In a 

 temperate climate like that of England types do not deter 

 riorate in the same way as, however well taken care of, they 

 do in a tropical one.
