experiments which have been lately performed in France, on the 

 Solidification of Carbonic Acid, and recommended the repetition 

 of these experiments. — Dr Charles Anderson exhibited a speci- 

 men of Cypraea guttata, a rare species, from Java ; and he also 

 communicated a description and specimens of a new species of 

 Cypraea, not described by Lamark, and which he denominated 

 C. castanea. The following is the character : " Testa ovato- 

 ventricosa, castaneo-fusca ; fasciis binis, latis, obscuris, satura- 

 tioribus ; marginibus incrassatis, albis, fusco-punctatis ; aperturae 

 extremitatibus intus roseo-rubeis." Shell of a bright chestnut- 

 brown colour on the back, the face and sides white ; the latter 

 marked with numerous spots of vivid brown of various intensity ; 

 the fauces brown, with a shade of red ; length 1|, breadth |, of 

 an inch. Received from New South Wales, by Dr Coldstream 

 of Leith, without any notification as to its particular locality. — 

 There was also exhibited a male specimen of the Rocky Moun- 

 tain Sheep (Ovis montana), which Professor Jameson had lately 

 received from the Colombia River from Dr M. Gairdner. He 

 remarked, that although its fur was of no value, it ought to be 

 introduced into this country, not only from the delicacy of its 

 flesh as food, and the fine leather to be prepared from its skin, 

 but also from its noble figure. The Professor stated that he had 

 many years ago brought this animal under the attention of the 

 Society, and it was to be regretted that no steps had as yet been 

 taken towards its introduction, it being, from its hardy nature, 

 likely to do well in our Highland mountainous districts, — Sir 

 Patrick Walker exhibited a specimen of the moth Phalaena 

 (Geometra) papilionaria, taken last summer in Aberdeenshire, 

 and new to Scotland. He then made some remarks on its geo- 

 graphical distribution in England and on the continent of Eu^ 

 rope, and mentioned several places, where it is found in great 

 abundance,
