We have since found it in another locality nearer Up- 

 park, where, within the last dozen years or so, they 

 were so plentiful that we have collected as many as 

 thirty or forty specimens in less than three hours on 

 several separate occasions. If we refrain from in- 

 dicating the exact spot where these treasures have 

 been found in such abundance, collectors, will, we hope, 

 kindly refrain from censuring our reticence, particularly 

 as we take this opportunity of informing them that we 

 shall be happy to exchange shells of this species for 

 others which we have not found here. The rose- 

 coloured mouth of this rare shell differs from those of 

 all other known British Helices, and during the period 

 of the animal's hybernation we find it closed with a 

 rather thick calcareous epiphragm. The shell itself is 

 of a reddish colour, and thickly studded with short 

 hairs. 



The Heath Snail (Helix ericetorum), inhabiting a 

 flattish white and banded shell, is the common snail 

 of our downs, and is often put in requisition for de- 

 corative purposes by our tender-aged rustic beauties, 

 who mount a number of the dead shells as necklaces 

 and bracelets, by stringing them together. The Ra- 

 diated Snail (Helix rotundata) is common in most of 

 our covers and under our beech trees, among moist 

 decaying leaves, wood and bark, the latter, by the bye, 

 we have often found an excellent bait for many of our 

 smaller snails, particularly the Helix aculeata. The 

 Wall Snail (Helix rupestris) we find in the crumbling 

 joints of old walls, and on the moss-covered tiles on 

 the roofs of buildings, and the Pigmy Snail (Helix 

 Pygm(za\ which from its minute size is difficult to 

 discover, is not improbably generally distributed. We 

 have collected several specimens in more than one 

 locality from the underside of recent chips of wood, 

 left on the open spots where large trees had been 

 felled. 



The Dull Twist Shell (Bulimus obscurus) is very
