PUPA. 45 



the colour of its coat generally partakes of that of the 

 part it is on. The animal is very similar to the pre- 

 ceding. 



Sah. Hedges, amongst dead leaves, under stones, 

 &c. ; and in woods, frequently on the stems of trees. 

 It is widely diffused, being found more or less abun- 

 dantly in all parts of the British Isles. 



The spurious species B. Goodalli, B. decollatus, and 

 B. clavulus, have been introduced by some naturalists 

 into the British Fauna, from living specimens having 

 been found in pine-beds, warmed by artificial heat, at 

 Bristol, Exeter, and other places. 



Pupa. Lamarh. 



Shell — Spiral, more or less cylindrical, abruptly obtuse ; 

 whorls numerous and close ; mouth mostly toothed 

 within, peristome reflected. 



Animal — Short, four tentacles, the upper ones developed, the 

 lower ones short, sometimes hardly discernible. 



P. UMBiLicATA. Dvapamaud. PI. VII, fig. 4. 



Cylindrical, brownish ; mouth lunate, provided with one tooth ; 

 peristome much reflected. 



This is the commonest, though by no means the least 

 attractive of the Fupce; its little ivory white lip forming 

 a beautiful contrast with the body of the shell, which is 

 of a dark chocolate colour, and polished. It approaches 

 nearest in form to muscorum, being about the same 

 size, and having a single tooth on the pillar ; but differs 

 in having the whorls more loosely set, and more inclined 

 to the axis. The peristome too, is not only thickened 

 but reflected ; whilst the lip of muscorum, although 

 thickened is not reflected. It is also a brighter colour, 

 and somewhat pellucid. The animal is of a lead colour 

 above, and white beneath ; the upper tentacles long, 

 lower ones short but distinct. 



Hah. This shell is very plentiful ; inhabiting chiefly 

 woods and hedge-rows, among the roots of grass or dead
