DENDROMUS RUDDI Wroughton. 



1910. Dendromus ruddi Wroughton, Ann. and Mag. Nat. Hist., ser. 8, vol. hy 

 p. 275. March. (Malikisi, Mount Elgon, British East Africa; type in 

 British Museum.) 



Specimens. — Thirty-four, from the following localities : 



Lado: Khino Camp, 1 (Loring). 



Uganda: Gondokoro, 1 (Loring); Kajuia, 1 (Loring). 



British East Afkica: Kaimosi, 31 (Heller, Turner). 



The specimen from Rhino Camp is duller in color and has slightly 

 shorter pelage than skins from Kaimosi, but is otherwise indistin- 

 guishable from them. The single specimen from Gondokoro is 

 immature, but is like young of same age in the Kaimosi series. The 

 Kajuia (near Hoima) specimen is typical ruddi. These three speci- 

 mens were included by Heller with his Dendromus lineatus ^ and 

 account in a great measure for the great variation in the distinctness 

 of the black median dorsal stripe which he attributes to that form.
