OP THE 



ZOOLOGICAL SOCIETY OF LONDON. 



January "^10, 1 8S9. 

 Prof. Flower, C.B., LL.D., F.R.S., President, in the Chair. 



The Secretary read the following report on the additions to the 

 Society's Menagerie during the month of December 1888: — 



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

 gerie during the montii of December was 74, of which 50 were by 

 presentation, 2 by birth, 8 by purchase, and 14 on deposit. The 

 total number of departures during the same period, by death and 

 removals, was So. 



Among these I may call special attention to the young Chimpanzee 

 purchp'^ed of Mr. Cross of Liverpool, December 6. This is appa- 

 rently of the same species as the specimen purchased October 24, 

 1883 (see P. Z. S. 1883, p. 464, and 1885, p. 6/3, pi. xli.), which is 

 still living in the Society's Gardens, and is, so far as can be at pre- 

 .sent ascertained, relerabie to the Bald-headed Chimpanzee, Anthropo- 

 pithecus calvus (Du Chaillu) '. 



Mr. Bartlett, in his communication to the Society on this subject 

 (above referred to), has pointed out the distinctions between this 

 Chimpanzee and the ordinary form (-4. troglodytes). 



The receipt of a second specimen is of great interest as tending 

 to confirm the validity of the species. A specimen of the common 

 Chimpanzee of about the same age being also in tbe Society's col- 

 lection at the present time, it is easy to make a comparison between 

 the two forms. 



' See on this subject " The Bald-headed Chimpanzee, " in 'Nature,' vol. xxxix. 

 p. 254 (Jan. lOtli, 1889).
