The deuticulated spines of the four last joints have the saaie lamel- 

 lifortn shape as in P. brevirostris. In the males the numbers of 

 these spines are 8, 8, 8 and 9 on the 7th — lOth joints. 



The legs are of equal length in both sexes ; the proportion of 

 the length of the joints is slighly different as the second joint 

 is longer in the males and the sixth in the females. The seventh 

 joint is very short in both sexes , the eighth slightly curved and 

 furnished with a row of numerous and nearly equal spines at the 

 side facing the claw, a few stronger spines being iraplanted at 

 the sarae side near the attachment of the seventh joint. The claw 

 is very long and slender (Fig. 5) and so are the auxiliary claws 

 which measure about | of the length of the claw. All the joints 

 are beset with long hairs , their number increasing from the fourth 

 to the sixth joint. 



In the females, when mature, the fourth joint (Fig. 4) is con- 

 siderably swollen: it contains the ovary, the ovarian eggs being 

 larger in the middle of the joint; the coecum of the intestine 

 which passes through the leg being also more strongly developed 

 (swollen) in the part situated in the fourth joint. 



The eggs of this species are no doubt large and not very 

 numerous : this may be concluded from the size of the ovarian 

 eggs. In one of the males the membrane which once surrounded 

 the eggs was found attached to the fifth joint of the ovigerous leg. 



The specimens collected and sent to me by Professor G. O. Sars 

 were found by the Norwegian Zoologist in mud dredged off 

 Christmas Harbour, Kerguelen Islantls. Here (Station 149) dred- 

 gings took place on January 29th 1874 at depths varying 

 between 120, 105 and 45 fathoms; from one of these depths the 

 new species of Pollene was taken. The occurrence of palps in the 

 males of this species (they are equally developed in tb e two males 

 I was able to investigate) is a curious but not quite unexpected fact. 

 Looking through the literature of the group, I find that Böhm *)
