The colour of the Wuoalouse is a darkish leaden hue, sometimes spotted with white. Ihe well-known PILL W'iODLOUSK, or PlLL ARMADILLO, are seen at the upper part of the illus'raton, one representing the creatuie as it appears â while walkinsj, and the other showing it when rolled up mto a shape. In this attitude it bears a strong analogy to the common hedgehog, and a still stronger to the manis, as in the latter case the creature is defended by horny scales that protect it just as the exiernal skeleton protects the armadillo. Vi hile rolled up, 'his creature has been often mistaken for a bead or a berry from some tree, and in one instance a girl, new to the country, actually ihreided a number of these unfoitunate crustaceans before she discovered that they were not beads. We now come to the last members of the Crustacea, creann-es which were for a long time placed among the molluscs, and whose true position has only been discovered in comparRtivelv liter years. Popularly they are cailed Barnaclt'S, but are known to naluraliata unaer the general term Cirrhipedes, on account.

V\ hen rdult, all the Cirrhiprdes are affixed to some substance, be'ng either set directly upon it, as the common amrn barnacle, so plentiful on our coasts ; placed upon a footstnlk of vaiiable length, as in the ordinary goose-, mussel ; or even sunk into the supporting substance, as is the case with the whale barnacles. When young, the Cirrhipedes are free and able to swim about, and are of a shape so loiallv different to that which they afterwards assume, that they would
