that it was evident that tlie supply of Giraffes from the Sudan, 

 which had been so long stopped, was again commencing. 



The Secretary laid on the table a small collection of Mammals 

 in spirit presented to the Society by M. Constantin Satunin,

 Natural History Departments of the British Museum, read a paper 

 " On OJcajna, a new Genus of Giraffidae, from Central Africa."
