Type locality. Sources of the Schebeli River, Galla country, East 

 Africa. Type in Berlin Museum. 



Geogr. Distr. Galla country. East Africa. 



Genl. Char. Smaller than L. matschie, and paler on upper parts. 



Color. Nose and lips black ; narrow line on forehead white ; top of 

 head, neck, and entire upper parts of body orange buff, the hairs being 

 purplish gray at base then ringed with black and orange buff, the tips 

 being the latter color and giving the dominant hue to the upper parts ; 

 arms and legs iron gray ; chin brownish black ; sides of head with the 

 long hairs covering ears ; sides of neck, throat, entire under parts, and 

 inner side of limbs, white ; hands and feet black ; tail black, tips of hairs 

 white. Ex type British Museum. 



Measurements. Total length, 1,280; tail, 690. Skull: total length, 

 96 ; occipito-nasal length, 82 ; Hensel, 65 ; intertemporal width, 40 ; 

 zygomatic width, 66; median length of nasals, 14; length of upper 

 molar series, 22 ; length of mandible, 68 ; length of lower molar series, 

 27. Ex type Berlin Museum. 



While having much similarity in color and markings to L. 

 MATSCHiE, the present species is paler. It varies also, and some 

 examples exhibit a considerable shade of yellow on the upper parts, 

 but it never becomes as dark as L. matschie. The type of L. ellen- 

 becki which is a young animal, has been examined and compared with 

 specimens of L. hilgerti in the Berlin Museum and found to agree 

 with some of them in every particular. L. ellenbecki will therefore 

 become a synonym of the present species. 



Mr. Pocock (1. c.) makes this a subspecies of ellenbecki, but 

 unfortunately he had no personal knowledge of the animal described 

 by Neumann under that name.
