34. Pilumnus maori , n. sp. Fig. 10. 
A Pilumnus, dredged in 70 fathoms off New Zealand, does not appear to belong 
to any of the described species of the genus, and I am therefore reluctantly compelled 
to add one more to the already long list of local forms of these crabs. 
Diagnosis. —Body and legs covered thickly in front and above, but more 
sparsely behind and below, with coarse hairs, yellowish in colour when preserved in 
spirit, some of the hairs much longer than the rest; body otherwise smooth save 
for five sharp anterolateral spines of the carapace, of which the first stands at the angle 
of the orbit, and the second is smaller than the rest, and very slightly more veil trail y 
placed. Regions of carapace rather faintly marked. Length of carapace in middle 
line three-quarters of greatest breadth, which is at base of last side-spine; width 
between orbits rather more than one-third of greatest breadth. Distance from outer 
angle of orbit to base of last side-spine somewhat less than that from base of same 
spine to hinder edge of carapace. Carapace strongly convex in front. Upper surface 
of front marked by a shallow groove, its edge with a faint median notch, and at its 
ends a forward trend to orbital edge, which bears below some sharp teeth irregularly 
set, and above some blunt tubercles and a shallow notch. No subhepatic spine. 
Flagellum of antenna naked. Chelipeds alike, but unequal, the right the larger ; 
arms with two spines near end of upper edge, wrists spinous on exposed surface, 
palms spinous above and on upper part of outer side, granulate on its lower part, the 
granules not in regular rows. Fingers black and distinctly toothed. Walking legs 
stout, with spine at end of upper edge of meropodite, two or three spines on upper 
edge of carpopodite, and a small, sharp end-claw. 
Length of single specimen (a male), 6 mm.

Diagnosis. —Carapace about two-thirds as long as broad ; its greatest width at
