The Lepas Anatifera is found on the coasts of England and Ireland, 

 but more frequently on that of Scotland. It adheres by means of its 

 branches, or pedicles, to the bottoms of ships, planks, logs, and 

 other substances floating in the water. 



This curious marine production consists of many unequal mem- 

 braneous branches, or arms, at the ends of which the Shells are dis- 

 posed in an irregular manner ; the larger clustering with the smaller in 

 groups, and forming bunches of various sizes. The branches are of a 

 ^uq red ; the Shells of a bluish violet. The animal within is a triton, 

 and is furnished with many cirrhi, or tentacula, with which it takes 

 its food. These tentacula are pectinated like feathers, and hang out of 

 the Shells when open. In the sixteenth century they were, in fact, 

 supposed to be feathers, and hence arose the whimsical belief that a 

 barnacle produced a goose*. Nqr was this a vulgar opinion only; it 

 was sanctioned by the grave details of learned naturalists of that time,
