No. 32. PATELLA. 



Limpet. 



Inhabitant a Slug. 



Shell univalve, subconic, and without a spire. — Linnmus. Patella limpet, 

 are so named from their resemblance to a little plate, and are more or less 

 conic without, and concave within. Some of them have the apex entire, others 

 perforated. The chamber limpets are distinguished by a peculiar kind of pro- 

 jecting process or lip within; most have the margin entire, but some have an 

 indent or fissure in that part; again, others are so spiral or wreathed in their 

 outward appearance, that they resemble rather the trocha than the patella. 



Limpets are found in great abundance on rocky coasts, adhering to rocks 

 and stones. The fresh water species attach themselves to aquatic plants. 

 They all affix themselves so tenaciously, that it is with difficulty they are re- 

 moved without injury. The common limpet frequents the same situation as 

 the perriwinkle, and is equally abundant. Although used by the ancients as 

 an article of food, it is seldom taken to market. Among the villages along 

 the coasts of Scotland, this shell-fish is frequently used; and the juice obtained 

 by boiling, mixed with oatmeal, is held in high estimation. It is considered 

 in season about the end of May. The chief excellence of the limpet js, 

 however, as a bait. It is easily obtained from the rocks, with a knife, by the 

 fishermen, and it is eagerly seized by all the latteral fish sought after. To 

 the haddock it is very acceptable.
