HELIX. 41 



an inch in diameter. Animal of a yellowish colour, with 

 dusky tentacles, the anterior ones being rather long. 



Hob. It is one that loves a luxuriant vegetation, in 

 damp shady woods, where the undergrowth of ferns, 

 nettles, and plants, flourish in unrestrained profusion. 

 It is consequently local, there being few recorded locali- 

 ties, and these chiefly in the north. We have met with 

 it abundantly in Airy Holme Wood,* near Great Ayton, 

 and also in woods near Doncaster, &c. It is peculiar 

 to Britain. 



H. PULCHELLA. Muller. PI. VI, fig. 20. 



Shell minute, opaque white, depressed ; mouth nearly circular, with 

 the lip much reflected. 



This little shell well deserves the name of " fair," for 

 though so small it is indeed a lovely gem, of a delicate 

 pellucid white colour ; its shape reminding us of the 

 Carocollce, which are found in warmer climates. The 

 large reflected outer lip is very peculiar and gives it an 

 elegant though unsymmetrical appearance, difficult to 

 describe. The umbilicus is large, exposing the upper 

 volutions. Animal white, upper tentacles long and 

 cylindrical. 



var. COSTATA, which is grooved longitudinally, is by 

 many marked as a distinct species, but its characteristics 

 do not warrant any such separation. 



Hob. It is by no means abundant, but is pretty 

 generally scattered over the country. Its most fa- 

 vourite resorts are rocks and stones, just beneath the 

 surface of the ground, where the roots of grass come in 

 contact with them. The variety is not so common as 

 the normal form, it is recorded as being most abundant 

 at Minching Hampton, near Exeter, on dry walls 

 amongst Sedum acre. 



H. ROTUNDATA. Muller. PI. VI, fig. 23. 



Shell depressed, deeply marked with striae, rufous, spotted with 

 chocolate ; umbilicus very large.
