The antenne (second antenne) are somewhat similar to those 
of Dactylopus Strémiz. 
The mandibles (Pl. 2. fig. 11) are also similar to those of the 
same species. 
The second maxillipeds (second foot-jaws) are moderately stout; 
the first and second joints are each provided with two small sete, 
as shown in the drawing (Pl. 2. fig. 12). The terminal claw, 
which is nearly as long as the second joint, is only slightly curved, 
and furnished with a small lateral seta. 
The first four pairs of thoracic feet are almost similar to those 
of Dactylopus Strémii (Pl. 2. fig. 18). 
The fifth pair (Pl. 2. fig. 14) have a general resemblance to the 
same pair of feet in Dactylopus Strémii, but the armature of 
the basal joint and the form as well as the armature of secondary 
joint are different; the basal joint is furnished with about five 
terminal sete, the two innermost of which are short and of 
nearly equal length, the next two are also subequal, but they 
are about twice the length of the others—all these four sete are 
m@derately stout; the fifth, which is close to the fourth, is com- 
paratively small and slender. The secondary joint is broadly 
ovate and is provided with six sete round the distal end; the 
“imyermost and the three outermost of these sete are moderately 
stout and plumose, while the remaining two are slender and 
elongate. 
The fureal joints are very short. 
The male differs from the female in several particulars, the 
following of which appear to be the more obvious :—The anten- 
nules (anterior antenne) are modified for grasping. The first 
joint of the inner branches of the first thoracic feet (Pl. 3. fig. 1) 
is shorter and proportionally much stouter than that of the 
inner branches of the first pair in the female. The end joint of 
the inner branches of the second pair of feet is prolonged into a 
stout and spiniform process, which extends beyond the end of 
the outer branches, and which bears one or two setx, as well as 
an elongated slender filament (Pl. 3. fig. 2). The fifth pair
