penial canal, into which a great azygous accessory gland and another divided 

 by a number of fine lamellae discharge. Two chitinized air-sacs, spiked 

 inside, are sunk in the geuital organs and communicate with the outer part 

 of the penial canal. The female organs are very simple. There is a large 

 stalked organ, resembling the so-called "sucking-stomach" of Diptera, 

 arising from the oesophagus ; no such organ has hitherto been known among 

 the Acariua ; it is proposed to call it the "receptaculum cibi." The pharynx 

 is exceptional in having a wholly flexible roof, instead of the chitinized one 

 found in allied Acari : this involves numerous other modifications. The 

 brain and nervous system are fully described. The respiratory organs 

 consist of a long tubular air-sac on each side of the body, which gives off a 

 multitude of fine unbranched tracheae and communicates by a single tracheal 

 trunk running along its exterior with the stigma by the mandibles. The 

 salivary glands are very large and elaborate, but allied to the Trombidium 

 type. The epipharynx is a highly specialized organ. The paper was 

 criticised by Mr. Sladen, Prof. Howes, and Mr. A. R. Hammond.

 in the chair. 



The Secretary read a report on the additions that had been made to 

 the Society's Menagerie during the month of March, and called special 

 attention to a young female Gorilla, Anthropopithecus gorilla, from French 

 Congolaud, obtained by purchase; a young male Markhoor, Capra megaceros, 

 from the vicinity of Peshawar, British India, presented by Col. Paterson, 

 March 18th ; a pair of a rather scarce species of Duiker Antelope, Cepha- 

 lophus coronatus, from West Africa, purchased ; and a Silver-backed Fox, 

 Canis chama, from Cape Colony, presented by C. W. Southey, Esq., of 

 Culmstock, Schoombie Station, South Africa. 



Mr. Sclater exhibited and made remarks on some specimens from 

 Nyasaland, lately sent home by Sir H. H. Johnston, K.C.B. Amongst 

 these was a fine head of the Sable Antelope, Hippotragus niger, from the 

 Zomba plains, and an example of the Brindled Gnu, Connochcetes gorgon, 

 or of a nearly allied form, believed to be the first specimen of this Antelope 

 sent home from British East Africa. 



Mr. Sclater also exhibited, by the kind permission of Mr. Justice Hopley, 

 of Kimberley, a pair of horns of the so-called Antilope triangularis, said to 

 have been obtained somewhere on the Zambesi. These horns are now 

 generally supposed to be abnormal horns of the cow Eland. 



Mr. W. E.de Wintou gave an account of a small collection of Mammals 

 from Ecuador, lately sent to the British Museum by Mr. L. Soderstrom, 

 H.B.M. Consul at Quito. It contained examples of only three species,
