JIah. Tasmania. 



Ti/pe. Adult male in spirit. B.M. no. 52. 1.15.50. Col- 

 lected and presented by Mr. Ronald Gunn. 



This fine species is evidently most nearly related to the 

 "West Australian i\^ major, but has a smaller and differently 

 shaped skull and shorter tooth-row. It is far larger than 

 the other Tasmanian form, xY. geoffroyi pacijicus, of which 

 Tomes's N. iinicolor is a synonym. 



It is named in honour of Mr. W. R. Sherrin, to whom 

 every mammalogist who has visited the Museum is indebted 

 for assistance, and whose admirable preparation of tiny skulls 

 and tinier baeula has so immensely helped in the mammalian 

 work done both by staff and visitors.
