sectivores a Hedgehog appeared to be common to judge from the numerous skins 

 scattered in the thornbush, and an Elephant Shrew was now and then seen tripping 

 through the bushes. Three species of Acomys were comparatively numerous but 

 otherwise no small rodents were observed except the peculiar Naked Rat {Hetero-^ 

 cephalus) which had its burrows in places where the soil consisted of sand. In the 

 hard packed gravel it probably would not be able to work its way. 



Although Guaso Nyiri is pretty well stocked with fish I did not see any signs 

 of Otters along its banks. The only water mammal there was the Hippopotamus. 



In the following list the names of the mammals observed in the thornbush 

 country north of Guaso Nyiri are enumerated. It may be seen from the same that 

 strange enough there are two Baboons, two Hyraxes and two Dikdiks and of these 

 one subspecies lives above and the other below Chanler Falls. This appears to indi- 

 cate two small zoogeographical areas meeting there.
