#.pama^'a,Limi.Syst.Nat. ed. xii. p. 1244;F.&H. iv. p. 46,pl. cxvi.f.2. 



BODY obtusely rounded in front, and narrowing behind to 

 a rather fine point, yellowish-grey, with sometimes a brown- 

 ish tinge, covered all over with large o^s al cubercles or granu- 

 lations, which are of a yellow colour with greyish interstices : 

 mantle furnished on its upper part with three fleshy and pro- 

 minent lobes : tentacles very long and nearly cylindrical ; ter- 

 minal bulbs on the upper pair small and globular : foot large 

 and broad, rounded in front and obtusely pointed behind. 



SHELL globular, thick and strong, opaque, of rather a dull 

 aspect, yellowish-white, with spiral bands of brown, which lat- 

 ter colour is more or less diffused over the surface ; these bands 

 are four or five in number on the last or body whorl, and are 

 sometimes confluent, and there are generally two or three (but 

 occasionally only one) on the penultimate whorl ; the surface 

 is also marked by numerous but irregular lines of growth and 

 very fine spiral or longitudinal stride : epidermis rather thick : 

 whorls 4^ or 5, extremely convex, the last occupying about 

 two-thirds of the shell : spire short and ending in a rather 

 blunt point : suture not very deep, but distinct : mouth nearly 

 round, slightly contracted and angulated above by the projec- 

 tion of the penultimate whorl : outer lip thick, reflected over 

 the umbilicus, margined inside with reddish-brown : inner 

 lip spread over the columella and scarcely distinguishable : 

 umbilicus narrow and small. L. 1-75. B. 1-75. 



Var. albida. Shell whitish or colourless. 



HABITAT : Woods, hedgebanks, and uncultivated places 

 in Surrey, Hertford, Kent, Oxon, Wilts, and Gloucester- 

 shire. The variety has been found by Mr. Brewer near 

 Reigate. There was at one time a popular notion that 

 it had been introduced into this country by the Romans, 

 because it is found near several ancient encampments ; 

 but there does not appear to be any other foundation 

 for this idea. The H. pomatia has not been found at 

 Wroxeter or York, or in many other parts of England 



* Operculated.
