ZONITES. 10 1 



Z. glaber was first noticed in this country in 1870 

 by Mr. Rogers of Manchester, and his discovery was 

 recorded in the 'Annals and Magazine of Natural 

 History' for May in that year by Mr. Gwyn Jeffreys 

 as follows : — *' My correspondent, Mr. Thomas Rogers 

 of Manchester, has added another species to this well- 

 worked department of our fauna. Specimens of a 

 Zonites which he has now sent me, collected by him 

 under stones at Marple Wood in Cheshire, prove to 

 be the Helix glabra of Studer, '- Fer. Prodr.,' No. 215. 

 Z. glaber has a wide range on the Continent, from 

 Normandy (where I have taken it), through France, 

 Savoy, Switzerland, Germany, and Dalmatia, to Epirus 

 in Greece. I also found the same species in 1846 at 

 Grassmere and in 1857 at Barmouth, but had over- 

 looked it. Mr. Rogers' specimens being alive, I 

 subjoin a description of the animal." The descrip- 

 tion has been transcribed above. 



It is remarkable that this species should have been 

 so long overlooked, for it seems to have a wide range 

 in this country. I have found it in Devonshire and 

 in Dumfriesshire, and many other localities have from 

 time to time been given for it since its discovery by 

 Mr. Rogers. Mr. Henry Groves informs me that it 

 emits a very strong smell of garlic when plunged into 

 boiling water.

 hue, which give a speckled appearance ; tentacles rather short 



Slightly shining.
