Bombay Natural History Society, I was able to start the Mammal 

 Survey in Burma under exceptional!}^ favourable circumstances. 

 The amount of local interest shown is particularly welcome as on 

 account of being the first work of its kind to be systematically 

 attempted in Burma, its results are expected to be of the utmost 

 scientific value." G.C.S. 



The specimens from the Ataran river were collected by Mr. J. 

 Pemberton Cook, while various others were received from other 

 members of the B. N. H. S. 



The collection is made up of 439 specimens containing 37 

 species in 24 genera. 



As was to be expected th3 majority of the species have not 

 previously been obtained during the Mammal Survey, there being 

 22 species to add to the list this time. 



Three varieties of monkeys were sent in, viz., Hylohates liooloch, 

 Simia rhesus and Freshytis ■pliaijrei. Bats were very numerous, 

 some large series being obtained among the Hipposideros, princi- 

 pally armiger, larvatus and lylei, this latter species was especially 

 interesting as Mr. Thomas had just described it on a single speci- 

 men from N. Siam. The squirrels were well represented also, and 

 this good series from the N. Shan States made it possible to 

 separate the northern variety subspecifically from the difficult and 

 variable group of Sciums atrodorsalis into 8. atrodorsalis shanicus, 

 as Mr. Wroughton had suggested some time ago. And in the 

 Mus hoochtga group I have made a new species, Mtts cookii, of the 

 present form, on its large size. Specimens of the Tui^aia have at 

 last been obtained, up till now Tree Shrews had been unrepre- 

 sented in the Survey collections. 



There are splendid series of the two species of EMzomys, 

 castaneus ? and cinereus, among the latter there are some very 

 large specimens. 



Thanks are due to all those members who helped Mr. Shortridge 

 by sending specimens, which have been included in an Appendix 

 to this report.
