472 NATURAL HISTORY. 



shell are thrust two rows of arms, or " cirrhi," as they are more 

 properly called. These cirrhi serve to entangle the small crus- 

 tacea or molluscs which pass near their sphere of action, and 

 which are then carried to the mouth and speedily devoured. 



The Bernicle is always found adhering to some larger object, 

 usually floating wood, and is very common on the hulls of ships. 

 Although the perfect animal is permanently fixed, it has been 

 discovered that the young are free and capable of locomotion ; 

 nor is it until a week or two has passed, that they finally settle 

 themselves. 



The name Anatifera or Goose-bearing, has been given to 

 this animal on account of the ancient story of the production 

 of the Bernicle-goose. This fable has already been related 

 under the article, Bernicle-goose.
