596 Mr. P. S. Kersliaw on 



L. b. alhoUneatus of Lukenya Moiintaia, Kenya Colony, 

 except in the colour of the ears, which are tawny ochraceous 

 instead of buff or cream-buff. There are three specimens 

 among tlie abundant material in the British Museum — one 

 from Fashoda, one from Bahr-el-Ghazal, and one from 

 Northern Nigeria — with just this light type of coloration, 

 all of which, so far as colour goes, are precisely similar to 

 the one under notice. These three occur as isolated ex- 

 amples in districts occupied by L. b. zebra and L. b. nigerioi. 

 It should be noted that the type of albolmeatus was also 

 unique, and I am not aware that any more examples have 

 come to light. These facts create a suspicion that these 

 light-coloured individuals may be only aberrations from the 

 true types.
