PATELLA LIMPET. 125 



This species is common in many parts of the 

 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 abundance 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 ciliated *f 

 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.
