896 NATURALISED FORMS OF LAND AND FRESH-WATER MOLLUSCA. 



BuLiMUS ACUTUS, Miiller, 1774. 



Confined to the seaboard of Central and Southern Europe. 



Mr. Petterd records in Journ. Conchology that during 1879 

 some examples of this species were forwarded to him. Dr. Cox 

 also had some specimens about same time. Mr. Kershaw recently 

 gave me examples (typical form) found by him in a Fitzroy garden, 

 Melbourne. Probably the original locality for specimens received 

 by Petterd and Cox. 



Helix similaris, Ferussac. 



A species of remarkably wide range, found in Cuba, N.W. 

 America, Natal, Formosa, Mauritius, Hongkong, Sand\\ich Islands, 

 Buenos Ayres, Brazil, Singapore, Bengal, Java. 



Originally recorded for Australia from the Frankland Islands, 

 collected by MacGillivray. Mr. Brazier, who had some of the 

 original specimens, remarks that they were H. aridorum, Cox, 

 and not similaris. The only locality known in Australia for H. 

 similaris, Fer., is Sydney, where it is found in plenty after rain in 

 gardens at Elizabeth Bay and at Guilfoyle's Nursery, Double Bay; 

 no doubt brought with plants from Mauritius. 



Cox remarks this shell is much like H. marcescens, Cox, found 

 by MacGillivray at the Clarence River. 



An interesting species which forms a thin, dry, and papery 

 epiphragm. 



Mr. Brazier tells us that amongst a large number of B. similaris 

 from a Glenmore-road garden he found a reversed specimen. 



Postscript. — Since the above was in type I have received from 

 Mr. Hedley the following note : — "Specimens of the slugs Limax 

 Legrandi, Tate, and Milax Tasmanic^ls, Tate, described in the 

 P.R.S. Tas. 1880, p. 16, were collected by me during a recent 

 visit to Tasmania. The first appears to be the European L. 

 agrestis, and the second, as anticipated by the author, to be L. 

 gagates, also introduced." 21st Feb., 1891.
