64 EINAR LONNBERG, MAMMALS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION ETC. 



in the Genets from Eritrea nor in the specimens from Guaso Nyiri. The latter have, 

 however, the lower lips dark, and in one of them the whole chin has a dark shade. 

 It is thus possible that this chin mark is not a constant characteristic. 



Considering all I think the best thing for the present is to regard the Genets 

 from Guaso Nyiri as belonging to the species Oenetta dongolana. In such details as 

 has not been already discussed they agree very well with the description published 

 in » Zoology of Egypt* except that the sfive narrow rufous lines on the back of the 

 neck» are not so sharply defined, and much mixed with black tips to the hair. 



The ground colour of she body is greyish white and the spots are rufous buff 

 mixed with black. Five longitudinal series of spots can be discerned, the two upper- 

 most of which have a tendency to become more or less confluent into stripes. The 

 black crest is sharply defined, the length of its hair is about 5 cm., and twice as 

 long as the other hair. 



To prove the resemblance with regard to the cranial dimensions the measure- 

 ments of the Suakin specimen recorded in » Zoology of Egypt* have been quoted side 

 by side with the corresponding ones of the Guaso Nyiri specimens of this collection 

 in the following table of measurements.

On the whole these skulls agree pretty well but the variability is proved to 

 be rather great as is seen from the differences between the two male skulls from 

 Guaso Nyiri for instance with regard to the length of the nasals. The difference in 

 the length of the palate (2,6 mm.) in the two skulls from Guaso Nyiri is chiefly due 

 to the difference in length of the skulls themselves. The length of palate is a little 

 more than half the length of the skull, and if the difference in basal length of the 

 skulls is about 4 or 5 mm., 2,6 mm. is only a natural difference in the palatal di- 

 mensions. 



' This skull is between 4 and 5 mm. longer than the other from Guaso Nyiri but it is a little broken 

 posteriorly so that the exact basicranial length cannot be recorded.
