following differences may be pointed out. Wilson’s species has the 
first tarsal joint half as long as the second, the claw about two- 
thirds the second tarsal joint, the auxiliary elaws one fifth the 
claw “the oculiferous tuberele much elevated’” ; whereas Kröyers N. 
hirtum has the first tarsal joint shorter than half the second, the 
second tarsal joint longer than twice the claw, the auxiliary claws 
two thirds the elaw, finally the oculiferous tubercle * humilis.” 
As the species dredged during the two cruises of the W. Barents 
shows in all details a great likeness with the species of Bell (after 
Wilson), the only difference being the length of the first tarsal 
joint, which in my specimens is shorter than half the length of 
the second tarsal joint, and as it is by no means identical with 
that of Kröyer, I think it is evident, that it must be regarded as 
N. hirtipes, Bell. 
In the figure and in the deseription of Bell it has emphatically 
been pointed out, that the movable claw of the mandible is much 
longer than the immovable; yet this has not been observed by Wil- 
son, neither is this the case with the numerous specimens I studied. 
So .I think it an error caused by. the eircumstance that Bell used 
a very feeble magnifying glass when studying his specimens. Feebly 
enlarged or seen with the naked eye the point ofthe claw which falls 
quite backwards is easily overlooked. I figured the two claws in fig. 
1 (Plate I ); @ is the immovable, b the movable one, armed with 
almost quite straight spines, whereas those of the immovable claw 
are slightly curved. | 
- The difference between the ovigerous legs of the two sexes has 
been described by Wilson. Yet he calls the male female and vice- 
versa. The ovigerous leg of the female I figured in Fig. 2; that ofthe 
male is much longer and strongly curved, figured in fig. 3. Especially 
the fifth joint is very stout and considerably swollen at the extrem- 
ity; it is “furnished on each side with a dense tuft of long hairs’ 
(Wilson); when the male bears eggs at ihe ovigerous leg, the foreside 
of the egg-mass is firmly pressed against the swollen part at the ex- 
tremity of the fifth joint. The so called denticulated spines I 
figured in fig. 4. The claw with the series of spines of a male in
