A history of the British sessile-eyed Crustacea . in the middle of itsposterior margin into a long tooth, which extends back-wards over the tail, but varying in length in individualsaccording, probably, to the period of their growth. Thisremarkable tooth, not having been represented byMontagu, has been overlooked in the descriptions of thegenus and its species by Desmarest and other laterwriters, although originally mentioned by Leach in the^ Dictionnaire des Sciences Naturelles. The seventhsegment of the body is very short, as is also the basaldivision of the tail, whereas the terminal division of thelatter is of large size, rounded behind, entire, and armedat each side with the greatly elongated, curved, lateralappendages, the outer division of which is setose, andthe inner appears to be obsolete, or very minute. Thefoot-jaws have the intermediate joints produced intorounded lobes at the inner apical angles. The antennaeare cylindrical, with the basal joints thickened. VOL. II. F F 434 SPHJIROMTD^. ISOPOBA.
