HELIX. Ill 



western parts of Scotland, and in Ireland generally. 

 This beautiful little mollusc lives among-, and feeds 

 upon, fallen and decaying leaves, especially those of 

 the holly and the fronds of some of the ferns. 



Dr. F. Buchanan White has " found it in the wooded 

 highland glens at an elevation of 1200 feet," and has 

 " met with it as far north as Ross-shire." He adds, 

 " though I carefully searched I have never been able 

 to find lamellata or any other shell among holly 

 leaves." — * Scottish Naturalist,' vol. ii. It may be that 

 the localities examined by him furnished a more 

 tempting repast, but in the south-west of Scotland I 

 always search among fallen holly leaves for H. lamel- 

 lata, and find it, as well as H. aciileata and Z.fulvus, 

 in considerable abundance upon them. When crawl- 

 ing its movement is unusually rapid, and it carries its 

 shell in an upright position, swaying it from side to 

 side as it advances, reminding one of the waddling of 

 a duck. It is very timid, and seems to be impatient 

 of the light. Being desirous of examining some 

 captive specimens, I found that the readiest way of 

 inducing them to show themselves was to allow a 

 gleam of sunshine to fall upon their shell, from which, 

 after a few moments, they would emerge, and crawl 

 away in quest of shade. The spire of the shell, es- 

 pecially at the apex, is frequently denuded of its 

 epidermis.
