Harpur Gamble, Esq., M.D., in the Chair. 
The Secretary exhibited the skull of an Antelope closely allied to 
A. euryceros, Ogilby, and read the following extract from a letter 
which he had received in reference to it from Capt. William Allen, 
R.N. :— 
“TI am sorry I cannot give you any satisfactory reminiscences of 
“the Antelope. It was, I should think, about three feet high, or 
** rather more, of a darkish brown colour, but I do not remember 
*‘ any white band across the forehead. The place where [ saw it 
«* was called Kokki, on a small tributary, the Abo, of the Came- 
“* roons river, or Madibama Dualla, in the Bight of Biafra. It wasa 
“« pestiferous locality and a foggy morning, so that I was anxious to 
“« get away as soon as possible, but left one of my black men to skin 
«it, and he only brought the skull and horns. I have no doubt the 
“* forests at the foot of the Cameroons mountain would furnish you 
“« with some valuable additions to zoology. I cannot say anything 
“ about the sex of the Antelope.”
