The sea-whips and sea-feathers are varieties of gorgonias,which are named from their forms. Some have shapes whichresemble branching shrubs; others are long unbranched rods,either straight or spiral. They attain a height of several feet andare of various colors. The colony has a horny axis surroundedby a living mass which resembles a sheet of animal matter. Thismass consists of polyps closely united, and has throughout its sub-stance spicules of carbonate of lime, making it a kind of calcare-ous crust or bark. In dried specimens this becomes very brittle,and is easily broken from the horny axis. (Plates XLVI, XLVII.) The sea-fans are colonies with a central, horny, flexible, andmuch-branched axis, covered, as in the sea-whips, with a layer ofunited polyps containing spicules of lime, which make a some-.
