This species was discovered in the latter end of 

 September, 1 851 , amongst moss and fallen leaves, under 

 an oak tree, at Stanton-on-the-Wolds, where three spe- 

 cimens were obtained. Professor Forbes, in his His- 

 tory of the British Mollusca [Vol. 4, p. 71], remarks on 

 this discovery, " Mr. Lowe, of Nottingham, has lately 

 sent us specimens fjim by himself at Stanton-on-the- 

 Wolds, a very anomalous locality," A specimen has 

 also been sent to Mr. Jeffreys, of Swansea, who like- 

 wise pronounces it an undoubted Helix revelata.
