meats, which were kept in a press or cupboard, but to prevent 

 its getting access to them when not wished, the cupboard was 

 kept locked. On one occasion the key had been forgotten 

 and left lying on the table, the chimpanzee noticed this, 

 secured the key, and when no one was present, proceeded to 

 unlock the door of the cupboard, but being unable to reach the 

 key-hole, drew a chair to the side of it, and getting up on it 

 unlocked the door, and so got access to the desired sweetmeats, 

 an act involving more than one process of that kind of ratiocina- 

 tion which is usually thought the exclusive property of man. 



Galago Murinus. — (Murr.) 



In addition to the information formerly given regarding 

 this interesting little animal, Mr Murray had received some 

 additional facts, communicated to him by the Rev. W. C. 

 Thomson, through Dr He wan. From these it appeared that 

 the little creatures are gregarious, or social rather, travelling 

 in small companies, and inhabiting a common nest; one of 

 which Mr Thomson got a glimpse of. He saw several indivi- 

 duals rush out of it as he passed, and it answered in its situa- 

 tion and description to the account he had received of them, 

 which was, that they were built on suitable forks on trees, 

 with a foundation of clay, and superstructure of dried leaves. 



Stenops, Potto (?). 



Two or three specimens of this curious loris have been re- 

 ceived, and the singular structure under the tongue (a develop- 

 ment no doubt of the frenum, but exceedingly like a bird's 

 tongue), as well as the rete mirabile of the arteries of the 

 limbs, was well shown in Mr Murray's preparations. 



The sublingual plate is also found in the Galago. although 

 less developed. 



Mephitis — Sub Genus Rhabdogale (sp. V) 



Mr Oliphant has received a specimen of an animal which 

 Dr Cleland, to whom he has presented it, refers to this genus, 

 but he has not yet satisfied himself as to the species. 



Anahyster — (Nov. Genus of Otters.) — Calabaricus Murr.
