PUPA. 97 



present in the adult whorls, and has some relation to the 

 young stage of the animal. 



The animal is rather stout, with long upper tentacles, 

 and very short hut distinct lower ones. Its colour is pale 

 hlue, deepening to dark grey on the neck and head. The 

 sides of the foot are steep, and, as well as the sole and 

 tail, very pale and nearly white. 



This is the commonest of all our native Pupas, occurring 

 everywhere under stones, among moss, on walls, and about 

 hedges, woods, and sand-banks. It is present in all our 

 provinces and outlying islands, and is found high up on 

 mountains, as well as on low grounds, and on the verge of 

 the sea-shore. It is a widely-distributed species, extend- 

 ing throughout Europe and into the north of Africa.
