The name Oenetta stuhlmanni has been based by Matschie on material from 

 Bukoba, and Mengo in Uganda. The skull has not been described, as far as I know, 

 and the description (]. c.) is not very detailed, but I think that the identification 

 above is correct. It is then of interest to see that a Genet which geographically 

 belongs to the Central Lake district extends its distribution to the eastern slopes of 

 Kenia and there meets the more eastern G. suahelica, and this zoogeographical fact 

 is in accordance with several others in other groups of animals as well. 



Mungos sanguineus rendilis n. subsp. 



It is connected with a considerable difficulty to ascertain to which race a spe- 

 cimen of small African Mungoose with black tail-tip belongs in consequence of the 

 great variability of these animals. Some years ago a synopsis of this ^Herpestes 

 gracilis group » was worked out by Wkoughton.' In this the author quoted recog- 

 nizes 6 species, and a number of subspecies which are divided in two groups according 

 to size as expressed by the length of the hind foot. The next subdivisions are based 

 on the shape of the skull and the colour. Now it appeared comparatively easy to 

 use this key, but in certain instances difficulties arise. This is for example the case 

 with the small Mungooses from the thornbush-country north of Guaso Nyiri. The 

 length of the hind feet in the male specimens from this locality is about 56 — 57 mm. 

 (without claws) which ought to refer them rather to the larger M. sanguineus group, 

 but in adult (even old) females from the same locality the same dimension is only 

 between 51 and 52 mm. (without claws). This measurement agrees thus nearer with 

 the corresponding one of the M. ochraceus group. In additition to this the brain 

 case as well of male as female skulls from the locality mentioned is rather strongly 

 inflated anteriorly, and the postorbital constriction is sudden. The skulls resemble 

 thus in this respect the M. ochraceus group according to Wroxjghton. As a con- 

 clusion of these facts it must be admitted that the limits between the M. ochraceus
