forms are also offered. — 4) Descriptions of new Mollusca, chiefly from New 

 Caledonia. By C. Hedley, F.L.S. A remarkable new Placostyliis from Dr. 

 Cox's collection, aberrant alike geographically and structurally, is described; 

 with further considerations on the range of the genus, dwelt on in a previous 

 communication. Several molluscan novelties obtained during a visit to New 

 Caledonia are made known, including a new Teinostoma^ a Diplommatina and 

 an Ischnochiton. — Notes: Mr. Edgar R. Waite, referring to some rats he 

 had sent to the Zoological Gardens in London, and to a paper he had contri- 

 buted to the Proceedings of the Zoological Society relative thereto, drew 

 attention to the fact that he had adopted W. S. Macleay's specific name of 

 arbort'cola, but rejected the generic title of Hapalotis for that of Mus. In a 

 note appended to the paper, Mr. Oldfield Thomas points out that the Sydney 

 Bush-rat is none other than a form of Mus raitiis^ and makes the interesting 

 atatement that the rats normally inhabiting ships are not, as is commonly 

 supposed. Mus deci/manus, but Mus rathis. — Mr. Palmer exhibited a number 

 of interesting objects from Lawson, Blue Mts., including a living Echidna; 

 a peculiarly marked spider [Celaenia excavata Koch) with two egg-bags 

 marked like the fabricator.
