HELICIDJE. 



Conchologists have been much puzzled whether this 

 shell is merely a variety of H. hispida or a distinct 

 species. The two shells are found in similar situations, 

 and are equally distributed. 



The following are the distinctions made by Dr. 

 Jeffreys : 



H. CONCINNA. 



Never globose. 

 Moderately glossy. 

 Umbilicus wide. 



Hairs scattered and de- 

 ciduous. 

 Animal darker, foot grey. 



H. HISPIDA. 



Globose. 



Very slightly glossy. 



Umbilicus narrow. 



Hairs thicker and per- 

 manent. 



Foot thick and yellow- 

 ish. 



Var. I. albida. White. 



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



11. H. HISPIDA (hairy). 



Sub-conic, thin, only slightly glossy; colour markings 

 the same as H, concinna, but darker ; whorls six and a 

 half ; spire blunt ; suture deep ; umbilicus narrow, but deep. 

 Covered with short white hairs arranged in spiral lines. 



Found under stones, timber, and among moss and 

 leaves ; common and universally distributed. It is a 

 pretty object when in full " plumage."
