Ty2Je. Male. B.M. no. 4.10.1.14. Original number 66. Col- 

 lected 26th May, 1904. 



This very pretty Dormouse may be distinguished externally 

 from G. mnrinus, to which it is probably most nearly allied, by 

 its olive-grey colour, and from G. na7ius and G. smithii by its lai'ger 

 size and more bushy tail. 



" These mice live about 20 feet from the ground in the big 

 trees in the gardens by the river. They are esj)ecially fond of 

 willow, seringa, apple, and camel-thorn trees. They are well 

 known by the natives, who call them ' Peba,' but then they call all 

 mice ' Peba' and all rats ' Tebude'."— i?. B. W.

" This species almost invariably has its burrows in patches of 

 ' wait-a-bit ' thorn-bush. I fancy they are preyed upon by the 

 meerkats, as I have seen scores of rats' and mice burrows that have 

 been scratched out by them. These rats move about a great deal 

 and do not stay long in any one burrow." — R. B. W.

This specimen so exactly matches the small series collected by 

 Mr. Andersson in Damaraland, identified by Mr. Thomas with 

 G. paeba schinzi Noack, that it seems best to regard it for the 

 present as a member of that subspecies. Schinz collected in 

 Ovampoland up to the edge of the Kalahari desert, and gave an 

 account of his itinerary in the ' Verhandlungen der Gesellschaft 

 f iir Erdkunde zu Berlin.' * G. j^C'^ba and its synonym tenuis 

 afibrd an example of Di-. Smith's habit of changing specific names 

 for others that he considered more suitable. 



'' I have found this species very plentiful whei-ever I have been 

 in Bechuanaland. These mice are nocturnal, though they are 

 occasionally to be seen on cloudy days." — R. B. W.

These specimens constitute the first well-preserved series ever 

 obtained of this very interesting animal. The British Museum's 

 previous material consisted of Smith's original example from 

 iNamaqualand, now much worn and faded, one specimen taken at
