182 LIMNiEADTE. 



as, or slightly longer than the spire, merely .subventricose ; 

 its convexity not flattened in the middle ; its basal decli- 

 nation rounded but not abrupt. Mouth usually stained 

 with liver colour or chocolate, neither capacious, nor very 

 prominent, of a peaked suboval figure, occupying one half, 

 or very nearly so, of the ventral length. Outer lip regu- 

 larly arched ; its edge scarcely at all sinuated. Pillar 

 lip raised at the edge, reflected, not so curved as in stag- 

 nalis. sometimes white, sometimes liver coloured : labial 

 enamel spread, not usually quite appressed, but exposing 

 at times a slight chink. Our largest specimen measures 

 fifteen lines in length, and six and a half in breadth. 



The reflexa^ umhrosa^ and elodes of Say, American Con- 

 chology, pi. 81, which form apparently but one species, are 

 scarcely distinguishable from this variable shell. 



The animal is dusky, nearly black, tinged with greenish 

 and olive. 



Generally diffused through the three kingdoms, inhabit- 

 ing ditches, ponds, and springs. It scarcely ranges so far 

 north with us asjpereger and truncatuliis do. 



L. GLUTiNOSUs, Muller. 



Subglobose, extremely thin and transparent, polished, pale
