in the young. The anterior border of the merus of the maxillipeds is not notched, as in typical

According to a note by the collector, the color is red; in the alcoholic specimens the hairs are red. 
The fringe of long hair across the front and the eye peduncles is a most conspicuous feature. 
Pilumnus nuttingi, sp. nov. 
(PI. xi, fig. 8.) 
Carapace subcircular, four-fifths as long 
wide. Hairs for the most part short, not disguising the 
areolation. Regions, as well as 
three subdivisions of gastric re- 
gion, plainly marked. Surface 
almost smooth. 
Front cut by a median V into 
two shallow submedian lobes un- 
armed; outer lobes not well sepa- 
rated from the small inner angle 
of the orbit. Three cuts in orbit 
shallow; margin unarmed, except 
for short spinule at outer angle. 
Antero-lateral about two-th irds 
as long as postero-lateral margin, 
cut into three teeth each tipped 
-with a forward-projecting spine. 
Postero-lateral margins converg- 
ing at an angle of about 55 degrees. 
Basal joint of antenna not quite 
reaching the front; a deep notch between this joint and acute inner angle of orbit. Lower surface of 
carapace partly granular. 
Chelipeds very unequal in both sexes. Arm with subterminal tooth above; wrist sparingly granu- 
late, sharply angled inwardly; hand stout, covered with acute granules, diminishing inferiorly, 
arranged mostly in rows; hairs absent from lower distal portion of larger palm. Granules on basal 
third of dactylus; fingers crossing when closed; prehensile teeth larger in pollex than in dactylus.
