and gardens about Hobart and Launceston, — this is the- 

 European Limax cinereus, and wbicli is also well established 

 about Adelaide. The question arises, may not Milax Tas- 

 manicus and M. nigricolus be conspecific with If. gagates of 

 the South of Europe ? but fhey both present the peculiarity 

 of a smooth shield ; and as regards M. nigricola, its distri- 

 bution favours the opinion that it is indigenous.
