a little granular and hairy above at the base, is also profoundly 
sulcate, and, as in the larger hand, its inner edge is more feebly 
denticulate than the lower finger. Both fingers present a few 
small tufts of short hairs internally along the inner edges. 
The ambulatory legs resemble those of the European P. hir- 
tellus, and are tolerably slender. The upper margins of the 
méropodites are armed with some acute spinules along their distal 
half, one of which is constantly found at the distal end; the 
other joints are unarmed. The dactylopodites are straight, a 
little shorter than the propodites, and terminate in an acute, 
slightly arcuate, horny tip. 
The anterior legs are everywhere covered with a short pubes- 
cence, except the smooth distal portion of the outer surface of the 
larger hand, which is quite glabrous; the inner surface of the 
palms and the fingers are also glabrous and naked. The ambu- 
latory legs present everywhere the same pubescence, and are 
fringed moreover along their upper and under margins with rather 
long hairs, especially along those of the last three joints.

According to Prof. Milne-Edwards, this new species differs 
from Pilumnus Peroni, M.-Kdw., by a less globular cephalo- 
thorax, the upper surface of which is more granular, by a less 
advanced front, ahd by more pointed and more delicate antero- 
lateral spines. 
P. cursor, A. M.-Edw., from New Caledonia and Upolu, is also 
closely allied to our species. In P. cursor, however, a typical 
specimen of which I have before me, the inter-regional grooves 
are more distinctly indicated, the whole outer surface of the larger 
hand is covered with granules, and the fingers of the larger hand 
are profoundly sulcate, at least in the typical specimen, which
