34: HELICID^. 



thinner, cf a lighter polish, and having the outer lip 

 white, which is a never-failing characteristic. Shell 

 about three quarters of an inch in diameter. 



Hab. Woods, hedges, and shady places. We have 

 never met with them except in limestone or sandy 

 districts. 



H. HYBRiDA. Leach. PI. VI, fig. 4. 



Globular, smooth, glossy, thin ; of a purplish brown colour ; lip a 

 subdued flesh colour. 



This distinct species must have been confounded by 

 several naturalists with some of the many varieties of 

 nemoralis. It is invariably of a brownish pink colour, 

 not banded, and has a fleshy pink mouth. Some con- 

 chologists suppose it to be a hybrid between nemoralis 

 and hortensis, hence its name ; but there does not seem 

 much ground for such a supposition. 



Hah. Under hedge-rows, probably only in lime- 

 stone districts. Locally abundant. Hackfall woods 

 near Eipon ; Hutton Rudby, Cleveland, &c. 



H. pisANA. Midler. PI. VI, fig. 8. 



Shell white, with numerous interrupted brown bands, both longitu- 

 dinal and transverse, wrinkled ; mouth not large, usually pink edged. 



This shell varies much in colour ; the bands are some- 

 times suffused almost over the whole surface, at other 

 times so indistinct as not to be easily detected. It is 

 generally half-an-inch or more in diameter, but varies 

 according to the situation in which it is found. 



Hah. Locally very abundant, but is confined to the 

 south-west of England and the south of Ireland ; in- 

 habiting dry, sandy plains, near the sea. Tenby, and 

 St. Ives, in Cornwall, are recorded localities. 



H. viRGATA. Da Costa. PI. VI, fig. 10. 



Shell white, with one or more brown bands, more or less perceptible ; 

 mouth red. 



Helix variabilis, La7n., §*c. 



If an illustration of the gregarious habits of some of 

 the molluskb is wanted, we could hardly furnish a better 

 example than H. I'irgata; i\iv\ ab,Ya}'s live in colonies.
