Severalforms are found in Cretaceous and Tertiary rocks, as PalaegaCarteri (Fig. 48) in the Cenomanian Chalk of Dover, andEosphaeroma Smithiin the Eocene of theIsle of Wight. Onetribe of Isopoda, theEpicaridea, live asparasites on otherCrustacea, notably onprawns, causing dis-tortion of their cara-paces. The distortedcarapace seen in somespecimens of Palaeoco-rystes, a crab from theCambridge G-reen-sand, suggests thatthey harboured theseparasites. The Order Amphipoda contains the sand-hoppers andfresh-water shrimps; small animals with a body flattenedfrom side to side, and with gills attached to the thoracicfeet. A few have been found in Tertiary rocks, but are notrepresented in the Museum. The Order Stomatopoda comprises but a single family,the Squ
