 ; Young individuals are generally of a light grey colour. I 

 have described the cranial tentacula as being three in number, 

 but I am not certain that the description is very accurate : 

 sometimes I can see one only, and sometimes I think I can 

 see more. bn£7 qiIT Jnsij s djjw 297kg

 Deriving much pleasure, a feeling doubtless partaken by 



.many other of your subscribers, from the short rambling 

 notes of Rusticus of Godalming, and other similar cor- 

 respondents, I venture to send you a short notice of the dif-

SHELL SNAILS AND SOME PLANTS MET WITH IN NORFOLK. 



Being a resident at Harleston, in Norfolk, during part of 

 the spring, I was astonished to find such multitudes of snail- 

 shells as are to be met with about there, so far more numerous 

 than I have seen in the midland counties, where I have 

 hitherto chiefly resided. The way in which I account for 

 their being so numerous is, 1st, the nature of the soil, which 

 affords plenty of calcareous earth, which, I believe, is neces- 

 sary for the construction of their shells ; and, 2dly, the form- 

 ation of the fences [generally of hawthorn], which afford pro- 



£ election to them during the winter; the quickset being placed 

 on banks of earth, which are frequently raised two or three 

 feet above the level of the fields, and abound in holes, into 

 which the snails creep ; and thus they are free as well from 

 the intrusive attacks of the peering thrush and blackbird, as 



2i/oalso from the severity of the season. 



The Commo?i Snail [Helix aspersa; the names are taken 

 from Turton's valuable little Manual of British and Fresh- 



-ihnWater Shells, which contains excellent coloured engravings of 

 each of the 126 ascertained species) I found huddled together 

 in troops of forty or fifty, fixed upon each other at the opercu- 

 lum, by means of a thick glutinous substance which the 

 animal has the power of secreting; a large shell having 

 sometimes three or four thus adhering to it. The snail
