HYOPHILOPSIS, A NEW GENUS OF POTTIACE^, 



With Further Contributions to the Bryology of India. 



By H. N. Dixon, M.A., F.L.S. 



(Plate 513.) 



Since my last article on Indian mosses in this Journal (Dec. 

 1910), I have received for study several small collections. These 

 include a further collection by Mr. Sedgwick, mostly about Fort 

 Purandhar, in the Poona District of the Western Ghats ; a small 

 number collected by Mr. C. E. C. Fischer, Deputy Conservator of 

 Forests in Coimbatore, on the Attapadi Hills, Mysore District, in 

 1910, and sent to me by Rev. E. Blatter, S.J. While from 

 Northern India Mr. L. B. Hall, F.L.S., has sent me a few mosses 

 collected by Miss Craig at an altitude of about 7000 ft., near 

 Ghoom, in the Eastern Himalayas. And lastly, Mr. W. R. Sherrin 

 has sent me the packing of skins in the British Museum of (a) a 

 flying squirrel from the Naga Hills, Assam, and (b) a squirrel from 

 Sikkim, each containing some interesting species. These, as well 

 as those mentioned in my last article, are dealt with here.
