eastern limits of its range. On the Northern Guaso Nyiro 
it is found along both banks throughout the low desert lands 
traversed by the river from its formation by the junction 
of the Guaso Nyuki and Guaso Narok down to its terminus 
in the Lorian swamp. North of the river it is found through¬ 
out the desert in the vicinity of springs or water-holes. 
Eastward toward the sea the limits of its range are not 
known except in the north where it extends as far east as 
the boundary of British Somaliland. As it has not been 
reported from the coast north of the Tana River, it doubt¬ 
less does not extend much farther east than the Lorian 
swamp.
