 Presented by Sir H. 11. Johnston. 



Two specimens were procured by Sir H. H. Johnston, one 

 at Baringoand one at Nandi, north of Mt. Kenia. Compared 

 with Abyssinian examples of P. doguera the present species 

 is a much darker animal and the bands on the hairs are paler 

 and more yellow, those of P. doguera being more ochraceous, 

 with less of the black showing. The general tone of tlie 

 Baringo specimen, while seal-brown, has a greyish tinge, 

 while that of Abyssinian examples is more ochraceous. The 

 cranial characters, however, will easily distinguish the present 

 form from its ally. 



lam indebted to my friend Mr. Oldfield Thomas for the 

 privilege of describing the species. 



LXXII. — List of a Collection of small Mam.mals made by 

 Mr. A. L. Butler in the Bahr-el-Ghazal. By R. C. 

 "Wroughton. 



The following is a list of the small mammals collected by 

 Mr. Butler between Renk, on the White Nile, and Dem 

 Zubeir, in the Bahr-al-Ghazal. The collection, though small, 

 was obtained under trying conditions. It is of special 

 interest, not so much on account of the new forms it contains, 

 as that it was made in a region whence little has been brought 

 since Heuglin's collection nearly fifty years ago.
