262 HELICID^. 



pillar, one on the pillar lip, and two or three on the inside 

 of the outer lip, the last springing from a white rib ; in half- 

 grown specimens the pillar lip has a spiral or longitudinal 

 fold : outer lip thin and slightly reflected, strengthened by a 

 strong rib, which is placed very near the opening of the 

 mouth ; outer edge abruptly inflected : inner lip thickened 

 in the adult : umbilicus small and narrow, contracted by a 

 keel or ridge at the base of the shell. L. 0'065. B. 0-04. 



HABITAT : Under stones, among dead and decaying 

 leaves, and at the roots of grass in woods and moist 

 places, in many parts of G'reat Britain from Skye to 

 Devon, as well as throughout Ireland. Mr. Brown has 

 enumerated it in his list of upper tertiary shells from 

 Copford. Abroad it has been noticed by Nordenskiold 

 and Nylander as inhabiting Finland, by Malm as Swedish, 

 and by Held as Bavarian. It does not appear to have 

 been found in France. 



This exquisite little snail is tolerably active, though 

 timid, and carries its shell nearly upright. The epi- 

 phragm is like that of its congeners. There is no rudi- 

 ment or trace of lower tentacles ; and my first descrip- 

 tion of the animal (in 1830) is incorrect in that respect. 

 I have since very carefully examined a great many living 

 specimens, and could not detect with a Coddington lens 

 even a speck in the place usually occupied by these ten- 

 tacles. Dr. Johnston found this species in East Lothian 

 at a height of 1200 feet. 



The form of the shell, and the strong transverse striae, 

 as well as the number and arrangement of the teeth, 

 will at once serve to distinguish this from any of the 

 foregoing species. 



It is the V. curta of Held ; and it closely resembles, 

 and may be specifically identical with, the Pupa milium 

 of Gould, which is a native of the United States.
