1887.] THE SECRETARY ON ADDITIONS TO THE MENAGERIE. 559 



The total number of registered additions to the Society's Mena- 

 gerie during the month of August was 104 ; of these 48 were 

 acquired by presentation, 37 by purchase, 12 by birth, and 7 were 

 received on deposit. The total number of departures during the 

 same period by death and removals was 199. 



The total number of registered additions to the Society's Mena- 

 gerie during the month of September was 136 ; of these 72 were 

 acquired by presentation, 25 by purchase, 2 by exchange, 7 were bred 

 in the Gardens, and 30 were received on deposit. The total number 

 of departures during the same period by death and removals was 

 109. 



Amongst these may be specially noticed : — 



1. A iled-aud-White Flying Squirrel (Pteromys alborufus), from 

 the province of Szechuen, in the interior of China, presented by 

 Percy Montgomery, Esq., of Ichang, China, and received September 

 9th. This fine large Flying Squirrel, which was described and 

 figured by Monsieur Alphonse Milne-Edwards (' Recherches pour 

 servir al'Hist. Nat. d. Mammiferes,' p. 298, pi. xlv.), from specimens 

 obtained by Pere David on the Tibetan confines of China, is quite 

 new to us, and is, I believe, also unrepresented in the National 

 Collection. 



2. An Urva Ichneumon {Herpestes urva), purchased September 

 17th. This Himalayan Carnivore is also new to us. It is well 

 figured in Hodgson's unpublished drawings in the Society's Library 

 (' Mammals of India,' vol. ii. pis. 128, 129). 



The total number of registered additions to the Society's Mena- 

 gerie during the month of October was 109, of which 4 were by 

 birth, 45 by presentation, 4 by purchase, 53 by exchange, and 3 were 

 received on deposit. The total number of departures during the 

 same period by death and removals was 93. 



The following additions are of special interest : — 



1. A young male Gorilla {Anthropopithecus gorilla), purchased 

 October 10th, of Mr. Cross of Liverpool, being the first Gorilla 

 acquired by the Society. 



The animal appears to be about three years old, and its height two 

 feet six inches. 



The Gorilla has been placed in the Sloths' House, in an adjoining 

 compartment to that of the female Bald Chimpanzee " Sally," 

 received Oct. 24, 1N83, so that there is now a good opportunity for 

 comparing these two forms of Anthropoid Apes. 



2. An Aye-Aye (^Ghiromys madugascariensis), purchased Oct. 

 28th, being the second example of this rare animal which has been 

 acquired by the Society. 



The following extract was read from a letter addressed to the 

 Secretary by Herr W. v. Nathusius of Konigsborn : — 



" I have the pleasure to send you by this, three preparations of
