MR. R. I. POCOCK OX A HYBRID AXTELOPE. 



T. senegcdensis. Another distinction made is that in T. barrovii 

 the sandy rufous of the back of the neck is carried up to the head 

 without the intervening shade of grey found in T. senegcdensis. The 

 intei'vening shade of grey occuis in a specimen of a young male of 

 T. harroi'll, and in my two specimens of that bird, which appear 

 to be adult, there are traces of it. The two species, however, are 

 easy to separate. T. senegcdensis is much paler in colour, especially 

 on the back, and in T. harrovii the patch of black on the thi'oat 

 is larger than in T. senegcdensis and runs up in a point towards 

 the chin. 



Mr. R. I. Pocock, the Superintendent of the Gardens, exhibited 

 two photographs (one of which is shown in text-fig. 1), kindly taken 

 by Mr. J. flblliott Darling, F.Z.S., of a young hybrid Waterbuck
