sixth segment, and consists of two successive plates. The 
two lateral pieces of the hinder edge are less independent 
than in Eupagurus, and there is a median notch, not a point, 
as in Chilton's and Lenz’s figures. The suit-anal valve* is 
present, though soft. The telson is carried folded under the 
sixth segment. The dorsal side of the abdomen, which in life 
is covered by the flat shell of a mollusc, as will be explained 
later, is smooth and only sparsely hairy, but the sides and 
ventral surface, which are exposed, are rough-skinned and 
much more hairy. 1 can detect no trace of sterna. 
The eyes, antennules, and antennae (Figs. 1 and 2) closely resemble those of 
Eupa</urus. The scales on the bases of the eyestalks are present, but hidden by the

rostrum. The antennary exopodite, by an extraordinary error, is figured by Filliol (loc. 
c/t. fig. 2) on the ventral side of the limb, and Lenz omits it altogether in his figure of 
P. platei. In P. edwardsi and P. tridentatus it is, as a matter of fact, situated in the 
of the abdomen of the 
specimen shown in Fig. 1,
