the latter being considerably the longer of the two in the male, 
with nine teeth along its outer margin, and one on the inner ; 
while the thumb has eight on the outer and one on the inner. 
The apical tooth of the finger fits in between the apical pair of 
the thumb. In the female, except for the three distal teeth, 
the denticulation of finger and thumb is fairly marked. In 
the largest male the upper margin of the hand measured 
24 mm., the lower including the thumb, 34 mm. In the female 
with eggs, the corresponding measurements were 8 mm., 
and 12mm. The second and third legs in the female are not 
much shorter than the chelipeds, but in the male they fall far 
below the chelipeds both in length and thickness. They are 
moderately hirsute with feathered sete, but with a bare spot 
on the under surface of the fourth and fifth jomts. The rather 
long fingers have spines along the inner margin, alternating 
in size. The fourth and fifth legs are tiny in comparison 
with the two preceding pairs, but with longer plumose sete. 
The fourth leg is a little shorter and more robust than the 
fifth, its fourth joint wider at the base than distally. In both 
pairs the seventh joint is small, curved at the tip, and antago- 
nising with a strong spine from the apex of the preceding 
joint. The vasa deferentia issuing from the first joint of 
the fifth legs in a dissected specimen measured 4 mm., the 
fifth and sixth joints together measuring 5 mm. 
In the female the first pleopods are short, the four following 
pairs elongate. In the male the first pair are tied together 
ventrally at the first joint, which is coalesced with the segment ; 
the second joint, as broad as the first, has a much larger brush 
of plumose sete, with which also the two sub-equal one- 
jointed rami are densely furnished distally. The second 
pleopods, sheltered in grooves of the first, are of much slighter 
structure, the first joint elongate, coalesced with the segment ; . 
the second not much longer than broad, the ramus produced 
to a point at each corner, the inner process much the longer, 
with a long spiniform termination. The third, fourth and 
fifth segments are provided each with a pair of very small 
oval plates, no doubt rudimentary, and apparently functionless 
pleopods. The sixth segment has also a pair of plates, which 
are larger and placed transversely instead of longitudinally. 
They are quite concealed in a dorsal view, and ventrally are 
hidden by plumose sete. 
The colour, judging by shght remains of it at various points, 
is a marbled red and white, beneath the fur or perhaps chiefly 
at points where the fur is scantiest.
