v>'orms, and how useful they were in a garden, and for many 

 years I never killed a slug without carefully examining it, in the 

 hopes of finding a vrorm-eating slug with a limpet's shell on its back. 



Now the question arises whether they a'-e different species, or 

 omnivorous, that is, both carnivorous and vegetari.ia? 



I have a vague idea that some authorities consider the genera 

 Glaudina and Sj>iraxis as carnivorous. 



NOTE ON CLAUSILIA BIPLICATA VAR. ALB I DA. 

 By J. E. Daniels. 



During my residence at Heidelberg, I found several examples 

 of this variety, and as might be expected from a species so numer- 

 ous and abundant as it is in that district, several other slight 

 variations in colour. One example I sliU retain in my cabinet 

 of a pale fawn colour, almost transparent, and only half the usual 

 length, owing to its having, from some cause, discontinued form- 

 ing shell ; the mouih is otherwise perfect. Any of your readers 

 having time and opportunity, should visit the woods at Neckarau, 

 a village nearer Mannheim than Heidelberg", where they will find 

 the lovely banded forms of Helix fruticum and Helix villosa in 

 great abundance. 



And as no doubt they are lovers of nature generally, they will 

 be much amused and interested in watching and possibly endea- 

 vouring to catch some of the exquisite green tree-frogs. One 

 drawback, if they are Ihin^kinned, is that musquitoes or huge 

 gnats, or some other abcminaticns of that kind swarm, and on 

 myself personally produced unpleasant sens; tions.
