PATELLA LIMPET. 125 



Cornish and Devonshire coasts ; it is never found 

 adhering to rocks, but is picked up after 

 storms, having been thrown on shore by the 

 agitation of the waves, along with the sea-weed 

 to which it is attached. It is found in abund- 

 ance at Sandwich, and always on the same 

 plant, the stalk of which the animal excavates, 

 probably for food, and forms a cell, in which 

 are sometimes discovered two or three of the 

 same species together. 



PATELLA Ungarica* 



HUNGARIAN BONNET. 



Specific Character. Shell conical, thin, semi- 

 transparent, finely striated longitudinally, and 

 wrinkled transversely ; summit much recurved, 

 and ending in two or three spiral turns ; it is 

 usually covered with a rough epidermis which 

 projects beyond the margin and forms a ciliatedf 

 border: beneath, the colour is reddish, the inside 

 glassy white, or flesh colour ; the base, which is 

 nearly circular, varies from one to two inches in 

 diameter ; the shell is rather more than half as 

 high. 



This species, so remarkable for its elegant 

 form, is found on the western shores of Britain, 

 but is not common. It belongs to the new 

 genus Pileopsis.
