C2D Inilt^od all its motions strike one as iiinn- onoro]inlarly known l)y the, iiaiue of All the species of this genus arc parasitic, residing on the whale and dol]thin. Tlu'ir liooked and diverging legs, anued with their sharply curvccl claws, enal)lo them to cling so tiuhtly that not even the swift miivciiieut through the \\ater, or the active exertions of tlie crea- ture on whicli they reside, are siilfieient to shake them from their hohl. Tlio dillerent species of Whale-louse seem to prefer various parts of the body, one sp(!cies cliiigiiig to tlie head, another to the side, and another to the tin. They .nil burrow rather deeply into the rough and thick skin of these iiiiiririe mannnalia. Their liodies are ilattened and rather oval; they have iive pairs nt'legs, all ]u-e]u!nsile; and on the second and third joints of the tho- rax, instead of legs there are long a]ipeiiilages for respiration, winch usually are bent over the back. In this illustration are severtil nf the Isopod Crustacea, the signi- lieatioii (if which word has already Ucn given. In all the Isopods tluM'c is a great i'esend)]ance to the common woodlouse, and many 111' tlieiii might easily lie mistaken lor lliose common and destructive lii'iiigs. The feniales have large lioiny plates on their hgs, so formed as to ])rodnee a large pouch under the thorax, M'hereiu the eggs are contaiue<l. In many species soiii(M)f the rings of the abdomen are connected so as to resend)le a single joint. The llAFKiN's ]\\y AurTUitrs is sliown at iig. A, and is one of the bi' of the whole order.
