P. vespertilio. The outer foot-jaws also resemble those of that 

 species ; they are covered with a short pubescence and fringed 

 with yellow hairs along their inner margins. The sternum and 

 the abdomen are covered with a short down, the abdomen, both 

 in the male and in the female, being similar to that of P. vesper- 

 tilio. The abdomen of the female is fringed with long hairs on 

 the lateral margins. 



The chelipedes are very unequal : in three specimens the right 

 hand is the largest, in the fourth it is the left. The anterior 

 margin of the basipodites is armed with three or four acute 

 granules. The arms scarcely project beyond the lateral mar- 

 gins of the cephalothorax ; the upper margin is armed with two 

 somewhat arcuate, dark-pointed, acute spines at the distal end, 

 the larger of which is situated a little behind the distal spiue, 

 which is itself accompanied by a somewhat smaller spine at its 

 base. Behind these large spines the upper margin is further 

 armed with four or five acute granules, which gradually decrease 

 in size towards the proximal end. The anterior margin of the 

 arm presents three or four acute teeth along its proximal half, 

 and the under margin is also granulo-spinulous. The under sur- 

 face of the basipodites and of the arms is a little granular ; the 

 concave inner and the scarcely convex outer surfaces are a little 

 punctate but nearly smooth, the outer surface being only slightly 

 granular near its margins. The wrist is armed, at its internal 

 angle, with an acute spine, and the upper surface is granulo- 

 spinulous, being covered with many small acute tubercles or 

 granules, especially along the inner margin and anteriorly (dis- 

 tally). In its outer appearance the larger hand is similar to that 

 of P. vespet'-tilio. The larger hand is nearly twice as long as high 

 (at the base of the fingers), the fingers being included, and quite 

 as long as the length of the cephalothorax. The convex outer 

 surface of the palm is more or less granulo-spinulous on the upper 

 margin and on a proximal area; around the articulation of the 

 wrist, the distal portion of the palm, and the rounded under margin 

 are quite smooth and glabrous. As already remarked, the size 

 of the granulo-spinulous area of the outer surface of the palm 

 is a little variable, the smooth portion of the outer surface being 

 in some specimens larger than in others. In one of the 

 specimens from King Island, the whole under margin of the 

 palm is smooth, and the granules are even wanting at the distal 

 end of the upper margin, so that the granulo-spinulous area only
