COCHLICOPA. 179 



pair very slender, covered with minute black specks, bulbs occu- 

 pying about one-fifth of their length ; lower pair rounded at the 

 tips, more transparent than the others and not spotted ; foot 

 rather longer than the shell, slaty-grey with a white margin, 

 rounded in front and ending in a finely pointed tail. 



Shell spindle-shaped, almost transparent, very glossy, pale 

 yellowish -brown, with very faint transverse wrinkles and still 

 finer and less distinct spiral striae, the former being almost, and 

 the latter quite, invisible to the naked eye ; periphery rounded 

 (acutely keeled in immature specimens) ; epidermis very thin ; 

 whorls 7, rapidly increasing, somewhat swollen, the penultimate 

 and body whorls much broader than the others ; spire produced, 

 apex obtuse, rounded; suture shallow, fringed with a narrow 

 bead-like band ; mouth obliquely pear-shaped, curved at the upper 

 angle and at the base, furnished near the centre of the base of the 

 penultimate whorl with a prominent twisted fold, which extends 

 some distance within the shell and sometimes has its crest 

 notched (close beside it, nearer the outer lip, there is often a 

 small denticle), with another strong, tortuous fold on the pillar, 

 and a triangular denticle near the centre of the inside edge of 

 the outer lip ; there are sometimes two or three additional den- 

 ticles between the teeth or folds ; outer lip sinuous, strengthened 

 by a slight rib which is frequently tinged with flesh-colour; 

 inner lip also sinuous and provided with a rib which is continued 

 along the base of the penultimate whorl till it nearly touches the 

 outer lip. 



Inhabits damp woods, among moss and dead leaves, 

 in many parts of England, but it is a rare species. It 

 has been found at Llandudno in North Wales by 

 Mr. R. R. Thomas ; in Scotland near " the Bridge of 

 Allan (Foulis), Dumfriesshire (Somerville)," ' Scottish 

 Naturalist,' 1872, and Captain Laskey is said to have 

 found it near Leith. 



It is gregarious, from six to ten individuals being 

 usually found associated together. According to 

 Moquin-Tandon, it is a sluggish creature, and when 

 crawling carries its shell in a horizontal position.
