downward curved spinule. The upper surface of the joint is 
hollowed. The third joint is produced below to a strong 
spine, which projects one-tnird the length of the fifth joint ; 
the fourth joint is short and bears a small distal spinule 
above. The fifth joint is cylindrical, slightly curved, and ex- 
pands slightly towards the distal end, reaclimg to about half 
the length of the ocular peduncle. The acicle is short and 
stout, reaching about as far as the spine on the third joint ; 
it bears, besides the acute apex, two short, strong spines exter- 
nally, and one near the base above ; it also carries several 
fasciculi of coarse setae. The flagellum is short, not much 
more than twice the length of the peduncle, and is non- 
ciliate. 
The mandibles have the edge of the cutting plate entire ; 
a narrow and not deep cleft separates it from the molar pro- 
cess ; into this tne terminal joint of the palp dips. The molar 
process is narrow. The palp is three-jointed, the second joint 
markedly compressea, its plane being transverse to the edge 
of the cutting plate ; the third joint, which is about as long 
as the two preceding ones together, is compressed and much 
expanded, its plane being parallel to the same edge. 
In the first maxillae the external branch has the second 
joint articulated below the apex of the preceding, presenting 
a bifid arrangement ; the distal portion is strongly reflexed. 
This branch bears a strong setum on the inner side near the 
base. 
In the second maxillae the third joint is compressed, 
tapering irregularly, the apex being without setae. 
In the first maxillipeds the third joint is twisted and 
turned aside so as to be partially hidden behind the exopod. 
The exopod is flagellate. 
The exopods of the two succeeding maxillipeds are very 
robust, compressedj and flagellate. The third maxillipeds 
have their coxal joints contiguous, the iscnium bears a row of 
corneous teeth on the inner side, and the merus a few spinules 
on the same side. 
The chelipeds are large and very unequal, the left one is 
the larger ; in it the merus is trigonous, reaching a little be- 
yond the eyes : it bears a few small, low tubercles, which be- 
come more numerous and larger towards the aistal end : some 
are minutely punctate at their summits. Tne upper surface 
of the carpus is strongly tuoerculate, the tubercles becoming 
almost spiniform on the inner margin. The hand is large 
and swollen, whitish (in contrast to the rest of the append- 
ages, which are red), ana finely granulate, the granules be- 
coming larger towards the inner side. The fingers open trans- 
versely, and are excavate, especially the immobile one, the
