A very easily recognized species, quite unlike any other. The 

 young (pi. 61, fig. 19) are regular in form, like a globose Succinea^ 

 and are irregularly bestrewn with small reddish-brown spots and 

 streaks, with some yellow streaks. 



The foot is comparatively large, and when active, in humid places, 

 the soft parts are probably not completely retractile into the shell. 

 When immersed in preserving fluids they retract completely, prob- 

 ably by parting with some of the water which inflated them ; and 

 in dry weather the living animal sometimes retracts entirely within 

 its shell. 



The snail is most frequently found on banana leaves, especially 

 those near the ground. It occurs also in the damp cavities of hollow 

 trees, and under the leaves of Diejfenbachia seguine. They are im- 

 mobile during the warm hours of the day, and wander abroad toward 

 evening, seeking food along the water's edge, eating the leaves of 

 Lepidium virginicum L., and Sinapis lanceolata D. C. They eat 

 lettuce freely in captivity. 



The type locality is Guadelupe; but upon the main island the spe- 

 cies is now r extinct, according to Maze". It survives on Marie- Galante, 

 and ihe specimens from Beau which I have figured (pi. 61, figs. 14, 

 15) are doubtless from the latter island. I can detect no difference
