Show 1904.] MR. R. I. R0C0CK OX A HYBRID AXTELOPE. 3 T. senegalensis. 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. senegalensis. The intervening shade of grey occurs in a specimen of a young male of T. barrovii, and in m y two specimens of that bird, which appear to be adult, there are traces of it. The two species, however, are easy to separate. T. senegalensis is much paler in colour, especially on the back, and in T. barrovii the patch of black on the throat is larger than in T. senegalensis 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. fiblliott Darling, F.Z.S., of a young hybrid Waterbuck Text-fig. 1.
