The engraving ofLcpas anatifera on the next page gives an idea of the shape of onegreat division of the Cirripedia—the stalked. This class is dividedinto pedunculated or stalked, and sessile or unstalkcd kinds ; thefirst are represented hanging on to pieces of wood, and the last maybe seen encrusting nearly every rock and piece of timber on mostparts of the sea-coast, and arc something like acorns in shape.Neither the pedunculated nor the sessile kinds ever move fromtheir fixed position, and the only evidence of life presented bythem to the ordinary observer is the occasional projection from theend of the shell of delicate fringed cirri, which thresh the waterin one direction. The cirri arc represented in the large engravinglike so many feathers projecting from the side of the shell of the 470 TRANSFORMATIONS OF INSECTS.

When a sessile barnacle is examined—andthey can readily be kept in the aquarium—the cirri will be seen toproject through a trap-door apparatus called the operculum, orlid of the shell. The shell is made up of five or more side piecesconnected together with strips of membrane, which are often bril-liantly coloured. The pieces or valves are composed of carbonateof lime ; but in some kinds of Cirripcdia they are formed, like
