native Australian slug or merely A . gagates introduced does not seem 

 to be known. Mr. Musson refers the specimens of Amalia he found 

 in New South Wales to A. gagates, but a sufficient comparison with 

 European examples does not appear to have been made. Another 

 noteworthy fact is the occurrence of three introduced species oi Avion 

 in New Zealand. It would be very interesting to hear what colour- 

 variation ^ . ^j^^r presents under its new environment. Mr. Musson 

 mentions A. ater as also introduced in the United States, but all the 

 records of its occurrence on the American continent are erroneous. 



Dr. Simroth has published a most important work on Slugs — 

 nominally of Portugal and the Azores, but really treating of most of 

 the European genera and species. This work was written some four 

 years ago, though only now published, and consequently is, in some 

 respects, hardly up to date ; but it contains a vast amount of valuable 

 information. A few non-European species are also discussed. 

 Philomyctis bilineatus (p. 368) appears to be P. coufusus. The Lintax 

 found by the " Challenger " expedition at Teneriffe and Tristan 

 d'Acunha, and referred by Mr. E. A. Smith to L. canariensis, was 

 really Agviolimax agvestis, form sylvatiais (Moq.), as shown by the 

 specimens, which are in the British Museum. This being the case. 

 Dr. Simroth's remarks on p. 280 will require modification, and Tristan 

 d'Acunha should not be given as a locality for L. avhorum on the map. 



Mrs. M. E. Cusack sends a small collection of shells found by her 

 at Petersfield, Hants., including Helix hortensis, form pliilbertia, and a 

 new form ftzVo/or — pink, with the upper part of the spire yellow ; 

 H. cantiana, H.lapicida, Limnoea truncatula, Vitvea (Hyalinia) cellaria 

 V. (H.) nitidula, and a small Cochlicopa Inbrica. 



Last year the Rev. J. W. Horsley sent the writer a list of the 

 British varieties of Helix nemomlis in his collection, among which the 

 following were new to the British list : — H. iiemoyalis, forms roya, 

 freminvillea, brotia, biguetia, pascalia, and gmelina. His collection also 

 contains the form hyalozonata, from Arran Is. (Ireland) and Deal. 



The above-mentioned form bicolor of H . hortensis also occurs by 

 the Thames at Kew, Surrey. A series of H. Jiovtensis found by the 

 writer there last year included forms liitea, avenicola, bicolor, bouchardia, 

 roseozonata, quiiiquevittata, astieria, lespesia, aleronia, and a few others. 

 The last two were new to the British list. — T.D.A.C.
