Dr. P. L. ScLATER, F.R.S., made some remai-ks on tlie letter 

 from Oapt. P. H. G. Powell-Cotton, published in the ' Times ' of 

 Sept. 27th, 1906, on the Okapi. 



A communcation Avas read from Mr. F. F. Laidlaw which 

 contained a description of a new species of Turbellarian obtained 

 during Dr. W. A. Ounnington's expedition to Lake Tanganyika. 



A communication from Mr. Oldpield Thomas, F.R.S., contained 

 a list of a second collection of Mammals made in Western Australia 

 for Mr. W. E. Balston, with Field-notes by the collector, Mr. G. 

 C. Shortridge. 



This second collection had been made in the Aa^ou watershed, 

 and consisted of about 350 specimens, of which a fine series had 

 been presented to the National Museum by Mr. Balston. 



In all 42 species were enumerated, and of these Mr. Shortridge 

 had given notes on the distribution and comparative rarity at the 

 present time, such notes being of particular value in the case of a 

 disappearing fauna like that of Australia. 



An appendix dealt with a small series obtained on Bunier 

 Island, Shark's Bay, on the N.W. coast of Australia. 



The sixth instalment of the results of the Rudd Exploration of 

 South Africa, prepared by Messrs. Oldfield Thomas, F.R.S., and 

 Harold Schwann, F.Z.S., was read. It contained an account of 

 the Mammals obtained by Mr. 0. H. B. Grant in the Eastern 

 Transvaal. Twenty-one species were represented in the collection, 

 of which one was new. 



Mr. J. Cosmo Melvill, F.Z.S., read a paper prepared by himself 

 and Mr. Robert Standen of the Manchester Museum, entitled 

 " The Mollusca of the Persian Gulf, Gulf of Oman, and Arabian 

 Sea, as evidenced mainly through the Collections of Mr. F. W. 

 Townsend, 1903-1905, with descriptions of new Species. — 

 Part II. Pelecypoda." 



It was a continuation of the enumeration of the Mollusca of 

 the above-named seas published in the Proc. Zool. Soc. vol. ii. 

 1901, and completing the Catalogue, the total number embraced 

 being nearly sixteen hundred species, many of these being found 

 to be new to science. Amongst the Pelecypoda, Tellina held the 

 premier place ; most orders and families wei-e, however, repre- 

 sented, and the result was a very I'efined and varied molluscan 

 fauna. Some interesting forms occurred amongst the Lardiacea ; 

 while the Pectinidm showed alliance and, in some cases, specific 

 identity with the Erj^thrsean faixna, lately so ably monographed 

 by Dr. Stura,n3^
