COPEPODA 



205 



which is placed on a small protuberance, is short and clumsy, and indistinctly divided into two 

 segments. 



Yq (St. V). Size of female from Ingolf St. 70 was 1-15 mm.; anterior division 0-90 mm.; urosome 

 0-25 mm. A voting male from same station measured 1-17 mm. 



The shape of the body is practically like that of the adult females; the first as well as the 

 fifth thoracic somites are fairly well marked in front. The antenuulae extend somewhat beyond the 

 end of the body, but the measurements are scarcely different. The third and fourth feet are like those 

 of the adult female, and so is the fifth foot, except for the very indistinct lateral seta. The only dif- 

 ference between male and female is found in the structure of the fifth foot, which is seen in PI. VIII 

 figs 10 a — b (textfigs 65 a— b). 



Yq (St. IV). Size of female as well as of male from Ingolf St. 19 was 0-95 mm.; anterior division 

 074 mm.; urosome 0-21 mm. 



The shape of the body is in main like adult female. The distal segments of the antennulae are 

 comparatively longer. The only difference between the sexes is found in the fifth pair of legs, the 

 structure of which is seen in figures (text-fig. 65 c and PI. VIII fig. 10 c). 



Occurrence. Of this species the Ingolf Expedition has taken a big number of specimens while 

 the S/S Thor has not taken any specimens in the samples taken with the young-fish trawl. 



In Davis Strait and in the Atlantic west of Greenland, the Ingolf Exp. has gathered it at 

 6 stations.
