THE BRITISH NATURALIST. 



[June 



close at hand, at a time when the surface was free from, and the climate extremely 

 cold. An animated discussion followed. 



Mr. E. D. Marguand then read a paper on "The Flora of Guernsey, compared 

 with that of West Cornwall." He remarked that though politically the Channel 

 Islands belong to England, that geographically, and to a great extent zoologically and 

 botanically they belong to France. Professor Babington gave the number of flower- 

 plants and ferns indigenous to Guernsey as 553, but he (Mr. Marguand) had 

 himself founed 660. For West Cornall 788 flowering plants and 25 ferns were 

 recorded. He called attention to the fact that whilst rarieties were always recorded > 

 the absence of species, generally common, was passed without notice, though this was 

 of great importance when dealing with the distribution of species. He instanced 

 many common English plants not found in Guernsey, and commented on each, and 

 and concluded with remarks on (i)— rare British plants, indigenous both in West 

 Cornwall and Guernsey. (2) — Plants, rare in England, but found in West Cornwall 

 with Scilly, but indigenous in Guernsey. ' (3) — Plants peculiar to the Channel 

 Isles, and Guernsey in particuliar, not occuring elsewhere in Britain though most of 

 them are found on the neighbouring coast of France. The paper throughout was 

 most interest and suggestive. Votes of thanks to Mr. Derrick and Mr. Marguand 

 brought the meeting to a close. 



Mollusca. 



Notes. 



We have lately received from Mr. C. T. Musson a very interesting 

 little paper on the naturalised forms of Land Fresh-water Molluca in 

 Australia, reprinted from Proc. Linn. Soc., New South Wales. 

 Several species have been introduced from Europe into Australia, 

 Tasmania, and New Zealand, all of which are discussed by Mr. 

 Musson. On p. 886, it is suggested that the slug described in 1824 by 

 Quoy and Gaimard a.s Liiiiax niegalodontes, may hsive been L.flavus, 

 introduced The present winter had supposed L..megalodontes to be 

 referable to the Janellinae, but in the light of Mr. Musson's suggestion, 

 this reference seems quite doubtful, and it is very possible that it was 

 L.flavHs after all. If so, the species must have been introduced in 

 Australia at a very early date. 



Another point that requires clearing up is that of the Australian 

 Amalia. No doubt Li max olivaceits Gould, L. pectinntus Sel., and 

 L. mauvus, Q. and G , are all the same species (although Mr. Musson 

 does not consider the first an Amalia), but whether they represent a
