February 27, 1849. 

 William Yarrell, Esq., Vice-President, in the Chair. 



The Seci"etary reported that he had received a letter from His Ex- 

 cellency Lieut. -Col. Butterworth, the Governor of Singapore, dated 

 Jan. 6th, in which he was informed of the shipment of some additions 

 to the Society's menagerie. The facilities possessed by Lieut. -Col. 

 Butterworth for securing the most interesting productions of the In- 

 dian Archipelago cannot fail to render the interest which he takes in 

 the progress of this Society of the greatest advantage to it. 



The Secretary further stated that he had received information 

 through the Chairman, that Mrs. Martin Stevenson, of Valparaiso, had 

 received from Don Francisco Javier Ovalle a pair of yomig Pumas, 

 captured on liis estate of Catapilco, which he was desirous of pre- 

 senting to this Society. Mr. and Mrs. Stevenson had obligingly 

 provided for the custody of these interesting animals, until they were 

 sufficiently mature to admit of their being transmitted to England. 



The collection had been increased since the last meeting by three 

 living examples of Lemur rvjifrons, Benn., and one of Nycticebus 

 javanicus.
