892 NATURALISED FORMS OP LAND AND FRESH-WATER MOLLUSCA, 



LiMAX MAXiMUS, Liniie, 1758. 



A large slug; colour varying from ash to yellowish-grey or 

 sometimes black ; often streaked or spotted with white or black ; 

 much wrinkled. From 4 to 6 inches long. 



Abundant in Europe from Finland to Corsica, Madeira and 

 Syria. Introduced into North America. Found in damp retired 

 and shady situations. 



New Zealand : Dunedin (Hutton). 



N.S.W. : common in and around Sydney (Brazier). 



Victoria : Ballarat, under logs in the bush five miles from city 

 (Musson). 



Tasmania : gardens and cellars at Hobart (Tate), and Laun- 

 ceston (Hedley). 



Mr. Brazier showed me an example of this species found at 

 Summerhill near Sydney, by Mr. R. J. Etheridge : pale grey with 

 black spots, evidently the Euroi)ean var. iniaculata. It approaches 

 somewhat L. psarus, Bourg., from Lombardy, as figured in Tryon's 

 Manual, (pi. 46, fig. 37), but the spots have no tendency to run 

 into lines. 



Mr. Hedley informs me that examples of L. maximus, obtained 

 in Mr. Petterd's garden at Ijaunceston, are infested with an 

 Acarus ; possibly the same as found under similar circumstances 

 in England. {L. flavits also suffers in the same way.) An 

 interesting fact. The question is, did the host when fully grown 

 bring out its parasite from original home, or has the slug, since 

 coming out of the egg here, contracted the habit of giving house 

 room to its uncongenial neighbour. An investigation of this 

 question might throw some light on the manner in whicli our 

 imported slugs (and their ally) have found their way here. 



LiMAX FLAVUS, Linne, 1758. 



Liinax variegatus, Drap. ; Limax Breckivorthianus, Heynemann, 

 recorded from Sydney, Malak. Blatt. XIV. pp. 131-133; L. 

 hicolor, Selenka, Ibid., XII. pp. 105, 173, XVI. 50. 



A yellowish slug, tessellated with white and black, or dark 

 brown, coarsely tuberculated, very variable as are all these
