1914. Dendromus sp. Gockerell, Miller, and Prixtz, Zool. Anz., vol. 44, p. 

 '439. June 2.3. 



Specimens. — Eighty-eight, from the following localities: 



British East Africa : Mount Gargues, 3 (Percival) ; Mount Kenia, 

 west side, 77, including 12 in alcohol (Loring, Mearns); West Kenia 

 Forest Station, 8 (Loring). 



This subspecies of the larger striped DcndrGTiuvs is abundant on the 

 Northern Guaso Njaro drainage of Mount Kenia. I can find no 

 reason for separating the Kenia specimens from the small series of 

 skins and skulls collected in the Mathews Range. They differ from 

 typical insignis in the darker, less reddish coloration, longer fur, 

 larger ears, and in the slightly larger braincaso. The difference in 

 color of the Kenia form was noted by Doctor Lonnberg in 1912.^ 



Young female skins from Mount Gargues have somewhat blacker 

 ears than any specimen from Kenia, but the ears of adult skins from 

 the two localities are alike in color and I believe the difference shown 

 by the young to be a matter of pelage. Much better series from 

 Mount Gargues are needed. 



The specimens from Gargues were collected at altitudes from 6,500 

 to 7,100 feet. On Kenia, Loring and Mearns trapped this species at 

 numerous collecting stations ranging in altitude from 7,500 feet up 

 to 14,200 feet.
