spines consist of a slender shaft with a swollen base; near the base is a pair of 
small teeth followed by two pairs of comparatively long slender ones ; the remaining 
four pairs are more slender and blade-like, graduating to a mere trace. The terminal 
claw is furnished with about nine slender teeth. Both denticulate spines and 
terminal claw are frequently very much worn. 
With regard to the Legs, all five are practically of the same size and proportions, 
and though there is a considerable amount of variation in this respect it is confined to 
narrow limits. They may attain a length of as much as 36mm. Of the three coxee, the 
first and third are sub-equal and together about as long as the second ; all, especially 
the third, bear a few minute sete, chiefly ventral. The proportions of the three 
following joints are approximately as 6°5:7 and 10; the tarsus and propodus are long 
and slender, the former being the longer. The limb is more or less covered with fine 
sete. On the femur they are scanty and for the most part small; a few longer ones 
are to be found along the shaft and distally. On the first tibia they are comparatively 
long and arranged in four indistinct rows, of which the lateral ones are not easy 
to observe. On the second tibia they become smaller and much more numerous, 
especially distally, and the distal fringe is strongly developed ventrally. The same 
arrangement holds good for the two remaining joints, but the ventral row is very 
strongly developed, the setee becoming almost spinous and closely set. The terminal 
claw is a powerful one, and is accompanied by two slender auxiliaries of about quarter 
its size. 
The Genital apertures of the female are found on the second cox of all the legs 
and in the adult they are distinct enough. The apertures of the male are at all times 
difficult to observe, and I have only been able to distinguish them on the three posterior 
pairs of legs. : 
Nearly thirty specimens of this species were taken in Winter Quarters, at all times 
of the year, and in depths ranging from 12 to 125 fathoms. They vary considerably 
in size, a variation obviously due to age, but in essential details they are in agreement 
except in one particular, and that is the articulation of the abdomen to the trunk; in 
certain cases among the more robust forms it is distinctly articulated. The trunk in 
all cases is seen to be very minutely scabrous when removed from spirit. The females 
are more robust than the males when the sexes can be separated, a feature which is 
most noticeable in the femora, but extends to the first tibiae. The males, as a rule, are 
rather more setose than the females. 
A few of the eggs borne by one of the males are hatched. On emerging from the 
eve the body is ovoid, and possesses three pairs of appendages. The cheliforus 
comprises a stout scape with one very long seta, and a small but well-developed chela, 
without teeth on the dactyli; a small proboscis lies below these. Details of the other 
two pairs of appendages cannot be seen without special preparation, which has not as 
yet been undertaken. Other specimens crawling about the egg-masses show the 
proboscis, chelifori, the palps not clearly jointed, and four pairs of appendages, having
