65 HELICIDE. 
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 followmg are the distinctions made by Dr. 
Jeffreys :— 
Hl. CONCINNA. H. HISPIDA. 
Never globose. Globose. 
Moderately glossy. Very slightly glossy. 
Umbilicus wide. Umbilicus narrow. 
Hairs seattered and de- Hairs thicker and per- 
ciduous. manent. 
Animal darker, foot grey. Foot thick and yellow- 
ish. 
Var. I. albida. White. 
Var. II. minor. Smaller, white, spire produced. 
Il. H. wisp (hairy). 
Sub-conic, thin, only slightly glossy; colour markings 
the same as H. concinna, but darker; whorls six and a 
half; spire blunt; sutwre deep; wmbilicus 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.”
