Sub-genus Yandeleuria, Gray, 1842. 



Sykes, in his Catalogue of Manimalia^ inhabiting the Deccan, published in 

 1831, mentioned a mouse which he believed to be new, and which he characterized 

 as light chestnut above, reddish- white below, and with a tail much longer than 

 the body. This httle rodent he described as of the size of a field mouse, and as 

 inhabiting only fields and gardens. 



In the following year, his specimens of this mouse had been forwarded to 

 London and were described by Mr. Bennett under the name of Mus oleraceus. The 

 great length of the tail and the comparative length of the tarsus as compared with 

 other mice were considered as characters sufiicient to distinguish the species from all 

 its congeners. 



In 1839, Mr. now Sir "Walter Elliot included tliis mouse in his tabular statement 

 of his Catalogue of Mammalia^ inhabiting the Southern Mahratta country as Mtis 

 longicaudatus, but in the text he described it under the name of Jf. oleraceus, and 

 explained that the f ortner term had been applied by himself to the species many years 

 before Bennett's description had appeared, but the name had never before been 

 published. He did not give any information regarding its structure, but recorded that 

 it lives exclusively in trees and bushes, up which it is able to run with great facility. 



Sir Walter EUiot had forwarded specimens of this mouse to the British Museum, 

 and in December 1842^ Dr. Gray proposed the genus Vandeleuria for their reception. 

 About the same time Sir Walter Elliot sent to the Calcutta Museum a series of 

 specimens of a small, very long-tailed mouse with grooved upper incisors, which 

 Blyth regarded as Mus oleraceus and the Vandeleuria of Gray. 



I obtained in the valley of the Nampoung, a frontier stream dividing Burma 

 from China, a small mouse which agrees in its grooved incisors and other characters 

 with the mice forwarded by Sir Walter Elliot. 



This mouse being preserved in spirit has enabled me clearly to make out the 

 characters of the feet which were not very distinguishable in the mounted specimens 

 of the mouse from Southern India w hich, however, are structurally identical with the
