Show PROCEEDINGS OP TUB SCIENTIFIC M E E T I N GS OP THE ZOOLOGICAL SOCIETY OF LONDON. • January 15, 1889. 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 Menagerie during the month 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 85. Among these I may call special attention to the young Chimpanzee purchased of Mr. Cross of Liverpool, December 6. This is apparently of the same species as the specimen purchased October 24, 1883 (see P. Z. S. 1883, p. 464, and 1885, p. 673, pi. xii.), which is still living in the Society's Gardens, and is, so far as can be at present ascertained, referable to the Bald-headed Chimpanzee, Anthropo-pithecus calvus (Du Chaillu) l. 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 (A. 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 the Society's collection at the present time, it is easy to make a comparison between the two forms. 1 See on this subject " The Bald-headed Chimpanzee, " in 'Nature,' vol. xxxix. p. 254 (Jan. 10th, 1889).
