when they are engaged in the important office of pro- 

 pagating their species; All the specimens of the 

 district were much more beautifully and distinctly 

 marked than any specimens I have met with in 

 England, and the shell was more frequently distorted 

 or hypertrophied than I have met with elsewhere, 

 possibly from being on the sandstone. 



6. L. arborum Bouchard-Chantereux. 



7. L. flavus L. 



8. L. carinatUS Z^ar//.— Apparently a variety of our English 



species, slightly darker in colour and the spots more 

 distinct. 



9. Arion ater Z. — Everywhere and in every shade of colour, 



from black to white and orange. 



10. A. hortensis Fer. — Not abundant. 



11. A. albus Z. — A pretty little species and distinct, under 



moss and dead leaves in woods, &c. 



12. Testaceila haliotoidea Dmp. — I have never found this 



species, and introduce it on the strength of a single 

 example found in the Castle gardens by an EngUsh- 

 man, and presented to, and preserved in the Museum 

 Lommel. 



13. Vitrina elongata Z'ra/. —A well-marked species and very 



abundant in damp situations, more especially in 

 winter and autumn. 



14. V. diaphana Drap. — It is difficult to me to describe the 



difference between this species and V. pellucida, but 

 it is slightly more globular, and is gregarious, the one 

 can withdraw its body entirely within the shell, which 

 our species in England cannot : habitats the same as 

 last, especially in the Castle gardens. 



15. V. pellucida Mull. — Not by any means common. 



16. Daudebardia brevipes Dmp. — Great was my delight, 



as one day when examining the contents of my col- 

 lecting box I found a solitary example of this rare, 

 pretty and interesting animal ; when I first picked it 

 up I was under the shade of the trees on the summit 

 of the Heilegenberg, and I imagined it was a variety 

 of V. elongata., but when I had extracted the animal 

 and saw the umbilicus, I knew how great a treasure I
