Maxillulae (Figs. 8, 9 & 10) The maxillulae are uniramous, the endopod forming the palp and the protopod bearing well-developed endites. They arise ventro-laterally, immediately behind the paragnaths and project vertically downwards. The proximal article of the protopod, generally considered to be the pre-coxa, is very short. The coxa is somewhat longer. There appear to be two endites (Fig. 8, mx1en1,mx1en2, Fig. 9), the proximal being pre-coxal, the distal arising from the coxa. The latter is, however, deeply bifid. It would seem useful to adopt the view of Muller (1894 et seq.) and Skogsberg (1920), who considered this endite to consist of two fused endites, comparable to the two distal endites of the cypridinids. The pre-coxal endite bears a series of stout setae, of which the two nearest the body are brush-setae, the more distal
