66 EINAR LONNBERG, MAMMALS COLLECTED IN CENTRAL AFRICA. 



Whether a quite young animal in milk-dentition, which has been collected at Beni 

 in Jan. 1914, belongs to this species, or not, is impossible to say. It might perhaps be a 

 young Crossarchus dybowshii Pousaegues about which the author quoted says: »Sa robe 

 en effet ne presente aucune zebrure». This holds good for the present specimen, but it 

 may depend on its youth, as well as its generally dull colour may be attributed to the 

 same cause. 



Poecilogale albinucha doggetti Thomas & Schwann. 



1 c? V4' 1 c^ Juv- & 1 ? 'U, 1 ? Vi2, 1 c? 'Via 1913, all from Rutshuru. 



The length of the skull of the largest male is exactly as great as that of the type 

 viz. 60,5 mm. The relative length of the stripes is, of course, somewhat variable. The 

 lateral stripes are, however, in none of these specimens two thirds of the length of the 

 median one, as is said to be the case in the type specimens of doggetti. The white of the 

 chin is in most of these specimens confined to the lower lip, and the white »patch on the 

 throat)) of the type is also absent in these specimens. These small differences are, how- 

 ever, of minor importance, and I do not hesitate to refer the specimens from Rutshuru 

 to P. doggetti Thomas & Schwann, the more so as the type locality of that form »Bu- 

 rumba, Ankole» (Nkole) is not very distant. 



In consequence of the variability thus found, P. doggetti apparently differs from 

 the typical P. albinucha only by its very much larger size, and such a characteristic does 

 not seem to be of more than subspecific value. It is probably due simply to more favour- 

 able natural conditions, and above all to more abundance of food. 



Canis adustus. 



A very large native flat skin. Length of head and body 83 cm.; tail 33 cm. 

 The lateral stripes are well marked, and the tail very black. 



Anomalurus jacksoni fortior n. subsp. 



Two male specimens from Masisi near Kivu, Febr. 1914, and one from the forest 

 west of Beni. 



These specimens appear to agree with De Winton's description of A. jacksoni 

 from Uganda with regard to the colour pattern, but they differ in some other respects. 

 The author quoted says for instance that in A. jacksoni the rigid adpressed hairs »on the 

 upper sides of the wings » are »confined to a small space barely 2 inches [=50 mm.] long 

 from the point of the expanding process backwards ». In the largest of the present spe- 

 cimens these adpressed black hairs occupy a strip along the margin of the membrane 

 of about 100 mm. from the process. 



The dimensions of the largest specimen from Masisi are also larger than those of 

 A. jacksoni, the distance from snout to vent being in the dry specimen about 400 mm.
