Genus SUCCINKA, Jh-apanmud. 



Testa ovato-pyramidata, cornea, imperforata, spira 

 brevi, anfractu ultimo magnd ; apertura mw/na, 

 lahio columellari frequenter unipUcato ; labio crterno 

 acuto. 

 Shell ovate-pyramidal, horny, imperforate, spire short, 

 last whorl large ; aperture large, columellar lip 

 frequently vfith a single plait ; outer lip sharp.

The shells of this genus are not to be distinguished 

 from those of Li/mncea by any definable character, yet 

 most of them, following the type Siiccinea piitris, are 

 of a more glossy and transparent texture. The animal, 

 however, differs materially from Lyinncea, and is 

 generally too large to be wholly withdrawn within the 

 shell. It is amphibious, but generally more inclined 

 to the aerial than to the aquatic clement, and lives on 

 reeds and other plants on the borders of rivers. In all 

 parts of the world, wherever there are rivers and river 

 plants, there are Succinece to be found, especially in 

 temperate climates, where they are most common. 

 Some of the Indian species are among the handsomest.

SucciNEA ELEGANS. Suc. testd elongatd, angustd, sub- 

 pyramidatd, succined, iranslucidd, Icevigatd ; spird 

 elevatd, anfractibus productis, rotund o*o-ovalis ;

The ELEGANT SucciNEA. Shell elongated, narrow, 

 subpyramidal, amber - coloured, transparent, 

 smooth ; spire elevated, whorls produced, roundly- 

 ovate ; last whorl elongated towards the apex ; 

 aperture subpyramidal, rather short.

Hab. England. Europe generally. 



The distinctness and roundness of the whorls of the 



spire marks a specific difference between this species 



and Succinta putris and S. gracilis. In both of the 



latter the spiral whorls are sloped and not rounded.

 pallide corned, laevigata, crassiusculd ; spird ex-
