Procavia brucei maculata subsp. nov. 



Type from Lukenya Mountain, British East Africa. No. 17504, 

 Field Museum of Natural History. Adult male (stage VIII). Col- 

 lected December 18, 1905, by C. E. Akeley. 



Characters. Similar to Procavia brucei and Procavia brucei 

 hindei but color paler and more grayish throughout; underparts 

 much less suffused with creamy or bufify, often nearly pure white; 

 ears more whitish; dorsal spot almost entirely pure white; upper- 

 parts more distinctly spotted than in any other member of the 

 brucei group, the dark spots in one specimen numbering between 40 

 and 50 and extending from the rump to the shoulders. Skull most 

 similar to that of hindei, differing from that of typical brucei in the 

 character of the basisphenoid which is broad and rounded on its 

 lower surface instead of being narrow and laterally channeled; nasals 

 broader and less emarginate behind than in brucei; audital bullae 

 smaller than in hindei.
