EAST AFRICAN MAMMALS IN NATIONAL MUSEUM. 127 



On account of its large size, and in the absence of typical specimens 

 of robustvs from the White Nile, it is referred to that early described 

 form. Although a younger animal than any of our specimens of 

 A. J), ruhescens, it has a larger skull, which is especially characterized 

 by its general elongation and greatly inflated auditory bullee. 



The following notes were made on the type-specimen of Atilax 

 paludinosus rohusius, by Heller: 



Type from "White Nile," no definite Iccality. Very old, skull with eutiires all 

 obliterated and teeth worn down flat. Skin much lighter colored than any other 

 specimen in the collection. Measurements of type skull (condyles cut away; bullae 

 broken: Back of buUte to incisors, 108; zygomatic width, G2.5; postorbital constric- 

 tion. 17; width palate across pm*, 37; condylo-incisive length of mandible, 83; upper 

 tooth row to front of canine, 42.5; width of m^, 6.3; width of m', 10,7; width of m^, 4.5; 

 length of 7^2, 6.

Specimens, — Four, from localities as follows: 



British East Africa: Mount Mbololo, 1 (Heller); Voi, 1 (Heller.) 



German East Africa: Mount Kilimanjaro, 2 (Abbott). 



The specimen from Mount Mbololo, an adult female with nasal and 

 basal sutures closed, agrees in all respects with the Kilimanjaro speci- 

 mens and unquestionably represents the same form. The example 

 from Voi, also an old adult female, differs from the type of rubescens 

 in its much larger auditory bullas and much more reddish coloration. 

 It is considerably larger than the female skull from Mount Mbololo. 

 The general shape of skull agrees better with rubescens, however, than 

 with the Guas Ngishu skull I have referred to robustus, and although 

 the specimen may represent a new race it seems unwise to name more 

 forms of this species until suitable series of skulls have been assem- 

 bled for study of individual and geographic variation, Color of skins 

 is doubtless of little value in differentiating subspecies of this mun- 

 goose, and the shape and size of the auditory bullae are unreliable 

 characters to use in describing new forms unless good series of skulls 

 prove their constancy.
