its more tropical range. Among the foreign species are several, like our 

 figured specimen S. patula, which better illustrate the character of the 

 animal, and show it to be more nearly allied to Bulimus and Helix than 

 to the Limneee, near which the Succinea mostly dwell. But though dwell- 

 ing in the vicinity of rivers, ponds, and marshes, and being to some extent 

 amphibious, their habit is to live on land. The faculty of living under 

 water is only extended apparently in instances of rare occurrence, to pro- 

 vide for the chances of occasional submergence by tides and floods. The 

 Succinea; are widely distributed in both hemispheres, including especially 

 the oceanic islands of the Pacific.
