THE HEliiMIT-CRAB. r 603 The colour of the Symnista is very pale yellow. Its claws are suddenly broad ratlier sliavp, and bent over at a right angle.

It is a small species, only two or three inches in len"-th, ° Thk general shape of the Oar-foot Crab points it out as allied to the preceding species, although the antennae are not so long, and their fringe not so conspicuous The name of Oar-foot is given to this species on account of the curious modification l,y whuh the lalse feet are developed into oar-like appendages with flat blades, which serve for swimming like the hinder feet of the swimming-crabs. The last ring of the abdomen is rlmiiged into a flattened and pointed paddle. The caraiiace is convex and of a tolerably ivjjular ova . This species is a native of New Holland, and never attains to any "veat size. An illustration of the Oar-foot Crab will be found in one of the succeeding pages. We now come to a singular group of oralis which are remarkable for their soft and shell-less tails, and the mode employed to protect them. From their solitary habits they are called , and from their extreme combativeness they have earned the title of Soldier-crabs. The best known of these Crustacea is the common Hermit-crab of England (Paaurus BinJiardiis), which is to be found plentifully on our shores. Like all its race, the Hermit- crab inhabits the shell of some mollusc, in which it can bury its unprotected'tail, and into which it can retreat when threatened with danger. The Hermit-crab usurps the deserted home of various molluscs, according to its size, so that, when young and small, it is found ill the shells of the tops, periwinkles, and other small molluscs ; and when it reaches full age, it takes possession of the whelk-shell and entirely fil
