DISTRIBUTION OF WORM-EATING SLUGS. 



The Editor of the "Journal of Malacology" is still desirous of obtaining living 

 specimens of worm-eating slugs (Testacellae), so as to add to the records he has of the 

 distribution of these animals in the British Isles, and which he hopes to be soon in a 

 position to publish. He takes this opportunity of thanking his correspondents for the 

 trouble they have taken in procuring him examples of slugs, and of expressing his 

 gratitude to those Editors who so kindly made known his wants last year.
