June I7th, 1902. — The Secretary read a report on the additions 

 that had been made to the Society's menagerie during the month of May 

 1902, and called special attention to an example of the Southern Anaconda 

 [Eunectes notaeus) from Paraguay, deposited by the Hon. Walter Rothschild, 

 F.Z.S., to a female Hartebeest from Angola (apparently Buhalis caama) , and 

 to three American Bisons [Bison americanus], from the Woburn Herd, pre- 

 sented by the President. — Mr. R. I. Po cock, F.Z.S., exhibited and made 

 remarks upon the nest of a Gregarious Spider [Stegodyphus dumicola) sent 

 home by Capt. Barrett-Hamilton, F.Z.S., from VredefortRoad, Orange River 

 Colony, South Africa. — Mr. Oscar Neumann exhibited specimens of 

 some new and interesting Mammals which he had discovered during his 

 recent journey through Eastern Africa, and called special attention to some 

 Monkeys of the genus Cercopithecusj and to various species of Hyraxes 

 {Procavia). — Dr. Walter Kidd, F.Z.S., read a paper on certain habits of 

 animals as traced in the arrangement of their hair. It was an attempt to 

 interpret, in terms of certain characteristic habits, the departures from a 

 primitive type of hair-arrangement. Shorthaired mammals, chiefly Ungu- 

 lates and Carnivores, were considered. The habits referred to were divided 

 into Passive (those of sitting and recumbent postures) and Active (chiefly 

 those of locomotion), and these were shown to match closely the variations 

 observed in the direction of hair in the animals concerned. — Mr. F. E, 

 Beddard, F.R.S., described the carpal organ which he had observed in a 

 female specimen of Hapalemur griseus that had lately died in the Society's 

 Gardens. He pointed out that this organ in the female differed in some 

 details from that in the male. — Mr. R. I. Pocock, F.Z.S., read a paper 

 on some points in the Anatomy of the Alimentary and Nervous Systems of 

 the False Scorpions of the Order Pedipalpi. — A communication from Mr. 

 H. J. Elwes, F.R.S., called attention to Mr. Lydekker's recently publi- 

 shed description of a new Elk, Alces hedfordiae^ based on some unpalmated 

 antlers and a skull of an Elk from Siberia, and off'ered a remark that he 

 thought it inadvisable to found a new species, or even a subspecies, on such 

 scanty material. — Mr. E. Beddard, F.R.S., read a paper, prepared by him- 

 self and Miss Fedarb, descriptive of a new Coelomic Organ in the Earth- 

 worm, Pheretima (Perichaeia) posthurnUj which consisted of a series of sac-like 

 structures on the floor of certain segments in the middle of the body. The 

 nature of these cavities was not quite apparent, but they were considered to 

 furnish another example of the commencing subdivision of the coelom in 

 the Oligochaete Worms. — Mr. Beddard also described some new species 

 of Earthworms belonging to the genus Polytorcuius, and made some remarks 

 on the spermatophores of that genus. — A communication from Miss 

 Igerna B. J. So Has contained an account of the Sponges obtained during 

 the „Skeat Expedition" to the Malay Peninsula in 1899 — 1900. The col- 

 lection contained examples of 29 species, eleven of which had proved to be
