plentiful in Vazon Bay, on plants of Brassici okracea (^wild 

 cabbage j and at the roots of (Armeria iiiaritima) sea pink. A 

 noticeable fact which I am unable to account for, is, that with 

 rare exceptions, all the shells on the plants, and there were many 

 thousands, were young of various ages having fragile additions to 

 the mouth of their shell of the season's growth, while all the shells 

 adhering to the walls of a small brick building near, Avere 

 " finished," having the usual number of whorls and ribbed mouth. 

 I examined a large number of plants in search of adult shells 

 before I discovered the specimens attached to the walls of the 

 hovel, after which I soon obtained as many as I desired. 



I have not met with any record of H. pisana having been found 

 in Guernsey before. My friend, Mr. Wm. Randall, the well 

 known enthusiastic and kind hearted marine zoologist, of Guern- 

 sey, mentioned a "banded shell of considerable size" which a 

 friend of his had been pleased at finding near the Castle at S. 

 Sampson's which I suspected was this species, but the only 

 evidence I could find of its having existed there was one dead 

 shell. 



Its habitat at S. Clement's Bay, Jersey, is well known to most 

 conchologists. I have had the pleasure of seeing it " at home" 

 there. It lives within a few yards of the ordinary sea level, and 

 I should imagine that at high tides the sea washes the " base of 

 its habitation." 



The largest shells here are much smaller than the largest Tenby 

 specimens, and the prevailing colour of the banded shells is lighter. 

 At Jersey f'and Guernsey_j the colour is umber of varying shades, 

 at Tenby it is sepia of greater or less intensity. 



In the Channel Isles I failed to find among many thousand 

 shells, spread along a large extent of shore, an albino, or even a 

 creamy-white opaque shell, the latter being common at Tenby,
