 bited specimens of the animal , the teeth and jaws , and the shell and eg^ of 

 Bulinms ollongus , and remarked briefly thereon. — Mr. G. B. Sower by,

3rd May, 1892. — The Secretary read a report on the additions that had 

 been made to the Society's Menagerie during the month of April 1892, and 

 called attention to a Finely-marked Owl [Pseudoscops grammicus) from Ja- 

 maica, presented by the Jamaica Institute, being the first example of this 

 Owl that has reached the Society. — Mr. S dater exhibited and made re-

 Madagascar, obtained from Southern Madagascar, and brought to this country 

 by Mr. Pickersgill, H.B.M. Vice-Consul at Antananarivo. — Mr. Oldfield 

 Thomas read a paper on the probable identity of certain specimens formerly 

 in the Lidth de Jeude Collection, and now in the British Museum, with those 

 figured by Albert Seba in his »Thesaurus« of 1734. — Mr. F. E. Beddard 

 read some notes on various species of aquatic Oligochaetous Worms that he 

 had lately had an opportunity of examining. Amongst these was a new form 

 allied to Acanthodrilus from the saline waters of the Pilcomayo , discovered 

 by Mr. Graham Kerr during the Pilcomayo Expedition. — Dr. Hans Ga- 

 dow read a paper on the systematic position of Notoryctes typhlops, the newly- 

 discovered Mammal of Central Australia, and came to the conclusion that 

 this anomalous form should stand as a distinct family of Polyprotodont Mar- 

 supials, allied to the Dasyuridae and the Peramelidae. — A communication 

 was read from Capt. H. G. C. Swayne, R.E., containing field-notes on

17th May, 1892. — Mr. W. T. Blanford, F.R.S., exhibited and made 

 remarks on the skin of a "Wild Camel obtained by Mayor C. S. Cumberland 

 in Eastern Turkestan. — In a paper » On the Geographical Distribution of 

 the Land-Mollusca of the Philippine Is.«, the Rev. A. H. Cooke, F.Z.S., 

 showed that the distribution of the different subgenera of Cochlostyla afi'ords 

 an interesting clue to the early relations of the various islands of the Philip- 

 pine group. Regarded from this point of view, the central islands, Samar, 

 Leyte, Bohol, Cebu , Negros, and Panay, with Luzon, were closely related, 

 while Mindoro and Mindanao were remarkably isolated even from their 

 nearest neighbours. An examination of the intervening seas accounted for 

 these phenomena, the depths between the central islands being inconside- 

 rable, while Mindoro and Mindanao are surrounded by very deep water. The 

 Mollusca of the tw^o ridges between the Philippines and Borneo, formed bj' 

 Busuanga, Palawan, and Balabac, and by the Sulu Archipelago , were partly 

 Philippine, partly Indo-Malay. Two remarkable groups of Helix, peculiar 

 to Mindoro , Busuanga , and Palawan , showed relations with Celebes and 

 possibly with New Guinea. The Mollusca of the Batan, Tular, and Talantse
