HELIX. 65 



white tinted brown, often marked with a whitish band ; 

 whorls six to seven, faintly keeled ; mouth furnished with a 

 broad white internal rib ; lip thin ; umbilicus almost hidden 

 by the reflection of the outer lip. 



This species is only found on the downs of Kent 

 and Sussex, near the coast, where it is abundant. 

 It is much smaller and smoother than H. Cantiana. 



9. H. RUFESCENS (reddish). 



Sub-conic, depressed, thick, semi-transparent, dull brown, 

 more or less reddish with a whitish line round the body 

 whorl, which is bluntly keeled ; spire short, obtuse ; mouth 

 semi-lunar, with internal white rib ; umbilicus narrow, but 

 deep. 



This is a very common shell in woods, hedgerows, 

 and under stones. The young are sometimes hispid. 

 The varieties are moderately common. 



Var. I. albida. White or colourless. 



Var. II. minor. Smaller, spire more produced. 



10. H. CONCINNA. (neat). 



Sub-conic, rather solid and glossy, light horn-colour, 

 sometimes streaked with reddish brown. A whitish band 

 is often found on the last whorl, which is faintly keeled. 

 Whorls six and a half ; spire obtuse ; suture deep ; mouth 

 semi-lunar, with white internal rib; umbilicus rather broad 

 and deep. Hairs, which are easily rubbed off, are found 

 scattered scantily over the epidermis.
