Accordingly the first, thoracic somite bear two pair of limbs viz. maxillipeds and pes I, and thus corresponds to two somites (cf. Hansen 1893). By examining females from Denmark I did not find any difference from those described except in the arrangement of the hairs of the ventral surface of the maxillar and maxillular somite, which is less complex than those figured. The only difference between males and females seems to be the more prominent median process of the labrum in the former Textfigure i. Catanns finmarchiciis G. Q.
