Dr. Henry Woodward, F.R.S., Vice-President, 

 in the Chan-. 



The Secretary exhibited a black-and-white sketch of a young 

 female Gorilla "(PI. LXIIL), made by Mr. Carton Moore-Park, 

 R.B.A., F.Z.S., from an animal that had lived for a few weeks in 

 the Society's Gardens in 1906. He stated that most of the 

 published figures of Gorillas appeared to repi'esent more adult 

 animals. Young Gorillas were much more human, and more 

 gentle and intelligent than was generally supposed. 



Mr. H. B. Fantham, B.Sc, F.Z.S., exhibited original drawings 

 of " T7-y2Kinosoma" hcdbianii (Certes), showing apparent cilia, 

 which might, however, be only threads of the sheath or undulating- 

 membrane which had become ruptured. These were first seen in 

 this organism by M. Fred Vies and himself at RoscofF this summer. 

 This parasite, which occurs in the crystalline style of the Oyster, 

 was compared with various Spirilla and Spirochsetes, and its syste- 

 matic position among the Protista was discussed. 



Mr. F. E. Beddard, F.R.S., F.Z.S., exhibited and made remarks 

 upon some examples of the Earthworm {Benhamia johnstoni) from 

 Mt. Ruwenzori, which had been entrusted to him for study by 

 Mr. W. R. Ogilvie- Grant. 



Mr. J. L. Bonhote, F.Z.S., exhibited one of the innermost 

 secondaries of the Knot {Tringa canutics) taken from a bird in 

 his aviaries. The specimen was remarkable from the fact that the 

 summer feather, instead of being cast at the autumn moult, was
