2IO COPEPODA 



Yo (St. V). Size of young female from lug. St. 19 was i-86mm.; anterior division 1-47; urosome 

 0-39. Another female from Thor St. 82 measured i-6 mm. 



The shape of the body is Hke that of the adult female; the comparative length of the abdominal 

 somites and the furcal rami is 7, 9, 9, n and 9. The antennulae reach the base of the furca; the 

 distal segments are comparatively longer. The inner lobe of the last segment of the endopodite of 

 the anfennac has 8 setae, in other respects the mouth appendages were scarcely different; no dif- 

 ference of interest was found in the structure of the natatory legs. The Jifih pair of legs in the female 

 is scarcely different from that of adult, but showed in the male, as seen in fig. 12 f PI. \'III, a rather 

 characteristic structure, as the left leg is much longer than the right one. 



Yc? (St. IV). Size of male from Ingolf .St. 27 was 1-38 mm.; anterior divi.sion i-i mm.; uro- 

 some 0'28. 



The difference between this and the preceding stage is found in the abdomen, consisting of 

 three somites, the comparative length of which was 6, 9, 12 and 7. The antennulae reach only to the 

 middle of the last abdominal somite. 



The first foot differs from that of preceding stage by the fused Re II — III; the second foot 

 showed the same feature, and its second basipodite has no outer tooth, while the spinulation was 

 scarcely different. The \&it fifth foot is somewhat longer than the right, and each foot consists of three 

 segments; no setae were observed. 



Occurrence. The Ingolf has gathered this species at 4 stations in Davis Strait: 



1/7 95 St. 27 64°54 L. N. 55°io L. W. V. 200—0 fathoms Temp, at surf. 3-9° C. 3 f?, i y c? (IV).

In Denmark Strait the Ingolf took it: 

 '% 95 St II 64°34 L. N. 31=12 L. W. V. 200-0 fathoms Temp, at surf. 8-2° C. i f?, 2 y? (V). 



In the Atlantic south of Iceland: 

 ■V5 96 St. 47 61=32 L. N. 13=40 L. W. v. loo-o fathoms Temp, at surf. io-6° C. 5 f$. 



The "Thor" has gathered the species at a single station: 



8/6 1905 St 72 57=47 L. N. ii°33 L. W. Yt 1500 M. Wire 2 f?. 

 '5/6 1905 St 82 5i°32 L. N. 12=03 L. W. Yt. 1200 M. Wire i y?. 



Distribution etc. This species has previously been recorded only from the west coast of Ire- 

 land, where it seems to be of frequent occurrence over deep water from the surface to 1000 fathoms,
