LÖNNBERG, MAMMALS FROM BRIT. E. AFRICA. 15 



tus »auribus extus fuscis», as if the latter author had meant 

 to say that the ears were »russet», but it is of course a great 

 difference between fuscous and russet. Tf the fuscous is 

 sprinkled with whitish something like »drab» may be obtained, 

 and it will thus appear that the ears of Heller's notatus is 

 not so very different from those of the typical adustus. 



It remains then to say a word about the presumed 

 smaller size of the skull of notatus. The condyloincisive 

 length of the type skull is stated to be 152 mm. The same 

 measurement of Sundevall's female type is 151 mm. The 

 skull of the old female from Juja farm is certainly much 

 larger, but as it is somewhat damaged in the the occipital 

 region no fully exact measurement can be recorded, the 

 condyloincisive length has probably been 159 mm. The other 

 specimens are not quite fuUgrown. 



It does not appear, however, as if there was any reason 

 for separating these specimens from adustus, and I cannot 

 help thinking that the noiatus might need somewhat better 

 foundation as well. 



Muiigos sanguineus Wroughton. 



A fine series of 8 specimens, one from Juja farm ^Vi 1914, 

 the others from Donya Sabuk ^^/i to ^^s 1914. 



Of these specimens the one from Juja is the darkest, 

 tending to melanism, especially on the back, but stränge 

 enough at the same time the light rings of the hairs are more 

 whitish than in the others. 



The condyloincisive length of the skulls of fully adult 

 males is about 66—67 mm., and of females about 64 — 64,5 mm. 



3Iuugos paludinosus rubesceus Hollister. 



Four specimens from Donya Sabuk, Febr. 1914. Two of 

 these are rather young and a third has no skull, but the 

 fourth is a fine old male. The skull of this specimen has 

 the following dimensions:
