174 MAMMALS FROM MOSSAMEDES. 



13. Mus pumilio Sparrmann. 



Thirteen specimens, from Humpata , June and July 1885. 

 Iris dark-brown, 



14. Mus nigricauda O. Thomas. 



One specimen, an adult male, from Otjipahe, 11 

 March 1886. 



The type-specimen, a male, described in 1882, has been 

 collected in Great Namaqualand, Hountop-river , by Mr. 

 Andersson in 1862. A stuffed specimen, an adult female, 

 is since the year 1876 in the collections of the Ley den 

 Museum: it has been collected on the same date (1 June 

 1862) as the type-specimen and is from the same locality 

 (Hountop-river) : it therefore apparently has belonged to 

 Mr. Andersson's collection. Another stuffed specimen , an 

 adult female , from West-Africa and presented by Sunde- 

 vall is also in our Museum. In Mr. Oldfield Thomas' opi- 

 jiiou — and I agree with him — it belongs to Mus ni- 

 gricauda. This specimen was labeled Mus paedulus nov. sp., 

 but uever has been described. 



The specimen collected by v. d. Keilen is larger in all 

 dimensions than the type; head and body 6". 7 (type 6".2), 

 tail 6".8 (type 5."8), earconch 0".9 (type 0".65). 



15. Mus couch a Smith. 



One specimen, a young male, from Humpata, June or 

 July 1885. 



Mr. Oldfield Thomas has seen this specimen and believes 

 that it belongs to this species. He has procured me a trans- 

 cript of Smith's description , which I reproduce here : » above 

 irregularly clouded , black and tawny , the later the pre- 

 vailing tint , particularly on head , back of neck and sides ; 

 beneath grey white ; tail moderate , brown above , white 

 beneath , and thinly covered with rigid hair. Length of body
