the mouth of the fhell. The tail of the animal has 

 a communication with the tubular part by which it 

 is affixed to the fubftance on which it adheres ; or 

 rather the tubular part may be faid to conftitute a 

 part of the animal, fince it has a contradlile power 

 at the pleafure of the creature. This fpecies of 

 Lepas is common on mofi: of the coafts of the Me- 

 diterranean, and is frequently found on our own. 

 It adheres to the bottoms of Ihips, and other fub- 

 ftances, and is fometimes found fingle, and fome- 

 times in clufters or groupes.
