ISTORY.— .4;7VyH ater (jttiT, black), is the 

 largest ef nur native species, and was first 

 made kiiewii by Dr. Martin Lister, iii 

 1674, under tlie descriiitive epitliet nf 

 Lhnn.r (iter, and lie afterwards, in 167S, 

 gave a good figure in Hist. Anim. Angl. ; 

 considerable confusion and uncertainty 

 has, however, arisen owing to the wiile 

 range of colour mutations to which it is 

 subject, and many species have lieen 

 created to receive them. 



The name ortpiricnnuii Cm allusirm to 

 its former use in medicine), bestowed 

 on this species by Baron Ferussac, was 

 intended not to 'separate any particular 

 form, liut to unite under one denomina- 

 tion all the different vaiieties and so- 

 called species into which this protean 

 slug had been divided. It has in other 

 parts (if its range alsij receiveil many 

 distinct names, liased upon tlie shglit 

 external modifications it has umlergone. 



With this species is associated the late 

 Mr. Thomas Nunneley, F.R.C.S., of Leeds, 

 whose careful and conscientions memoir 

 of 1837 upon the anatomy of the present 

 one of tlie precursors of the modern scientific 

 stuay 01 Slugs, ano u, is .o f,e regretted that his professional career as a 

 distingui.shed and skilful surgeon did not leave him leisure to follow up Ins 

 anatomical studies of the moUusca.
