The Secretary, on behalf of Col. Sir A. H. McMahon, K.C.I.E., 

 C.S.I., F.Z.S., exhibited some specimens of the Cicada. {Sena 

 qucerula) collected at Quetta, Baluchistan, which had been visited 

 with great swarms of these insects in 1909. Similar swarms had 

 been known to occur at intervals of about six years. The Cicaxla 

 bores a hole in the ground, apparently intended merely to hold 

 the insect during its pupa stage. Each hole is separate and quite 

 open, holds only one pupa, and is bored verticalty to a depth 

 varying from 1 1 inches to 2 feet. In diameter it is about half an 

 rich, but widens slightly at the bottom. 



Dr. R. T. Leiper, F.Z.S., exhibited a series of specimens of 

 Entozoa, viz. : — 



(a) A sexually mature Guinea-worm (Dracunculus medinensis) 

 that had recently been found by Mr. Charles Grey in a Leopard 

 at Broken Hill, N.W. Rhodesia. Guinea-worm is normally a 

 parasite of man, but very occasionally it attacks horses and dogs. 

 This is the first record of its occurrence in the Leopard. The 

 discovery of the parasite in Rhodesia is also of considerable interest 

 for the Equator forms the southern limit of the endemic area of 

 the disease amongst the natives of Africa. 



(b) A Nematode from the body-cavity of the Tsetse- fly (Glossina 

 palpalis), found by Dr. A. Gray, R.A.M.C, at Entebbe. The 

 specimen, '6 inches in length, is an immature female Mermis. 



(c) A series of round worms from horses that had lived in 

 London for several years. The specimens included : — Ascaris 

 megalocephala, Oxyuris curvula, Stro7igylus equinus, Strongyhis 

 edentatus, Strongylus vulgaris (developmental forms of this worm 

 causing aneurisms of the abdominal aorta), Triodsontophorus serra- 

 tus, Gyalocephalus capitatus, Cylichnostomum elongatum, Cylichno- 

 stomum sp. n. The Sclerostomum tetracanthum Mehlis was absent. 

 The parasites were present in considerable numbers, and it seemed 

 evident that they reached London as semi-dried larvae encysted 

 npon hay. 



Dr. Leiper also gave an account of the Entozoa of ffippopotaimis 

 amphibius, collected by him in Uganda in 1907, when a member 

 of the Egyptian Government Survey. 



The Hon. Paul A. Methuen read a paper " On a Collection of 

 Freshwater Crustacea from the Transvaal," communicated by 

 Prof. G. C. Bourne, D.Sc, F.Z.S., containing an account of some 

 Entomostraca collected from Lake Chrissieand other pans or lakes 

 in the Carolina District, which is high veldt country lying 

 near the borders of Swaziland. The paper also gave a short 

 description of the " lie " of the lake and notes on the geology of 

 the district and the composition of the water. 



Dr. Joseph Pearson, F.L.S., presented two papers, communi- 

 cated by Prof. W. N. Parker, Ph.D., F.Z.S., on Holothurioldea 

 from the Kerimba Archipelago. Portuguese East Africa, and from
