lected previously between Wareham and Weymouth, in Dorsetshire, 

 I was unacquainted with any cabinet or collector, except Mr. R. 

 Damon of Weymouth, and in Heidelberg there was no one who 

 took the slightest interest in the matter at that time, with the ex- 

 ception of Mr. Lommel, of the Sandgasse, who dealt in minerals 

 and fossils, but in working up the Ferns and Flora, I soon discov- 

 ered how many new species there were to my eyes, and I had the 

 honor and pleasure of adding several new species to the known 

 fauna of the district, and also of turning the attention of several 

 students, native, English and American to the pursuit. 



1. Li max agrestis, L. — calls for no special note. 



2. L. brunneus, Drop. — Mr. Jeffreys and M. Moquin-Tandon 



are now I believe fully alive to the fact of this very 

 pretty animal being a good and distinct species, it is 

 never found anywhere but in swampy situations, it 

 never attains to the size of the previous species, it is 

 a deep rich brown color, and the slime or mucus is 

 colorless and not so viscid as many of its congeners. 



3. L. tenellus, Miille?: — Another small species, whitish-gray 



in color, something like Z. agrestis, but here again the 

 secretion is colorless. If I am correct in the name of 

 this slug, the only habitat I remember to have seen it 

 in, is a ditch or small stream running by the side of 

 what is called the "rent's tower" (gesprengte Turm ) 

 in the Castle. 



4. L. cinereo-niger, Nihson. — This is a grand animal un- 



known in Britain, it is the largest slug I know, it lives 

 in the forests, and is always to be found wandering 

 about in damp weather, provided it is moderately 

 warm, I have seen them when stretched to their full 

 extent, upwards of seven inches long, in color bright 

 polished black, with a broad white stripe running down 

 the entire length of the belly, with a margin of black 

 on each side, occasionally, but rarely, pale dusky olive 

 green, and white varieties are met with. The lower 

 portion of keel is sharply keeled, shell in shape some- 

 what similar to L. flavtis, thin, brittle and when fresh 

 almost transparent. 



5. L. maxim us, L. — Everywhere abundant in the open coun- 



try, especially on old walls, this species is more noct- 

 urnal in its habits than the last, and like the pretty 

 Z. arhorum, suspend themselves heads dowTiwards
