COPEPODA 



Y. (St. V). Size. 6 — 6-8 mm. (4-5 + 1-3). 



This stage shows the same differences from the mature females as in Cal. fhiiiiarc/iiciis G., 

 it differs from that species, as in the adult females, by a pointed lateral corner, fewer teeth in the basipod. II 

 l^es V marginally, by larger size and greater transparency. 



Y. (St. IV— I). Size, of St. IV 37 mm. (g-g + 0'8) — 4-5. Difference from Cal. finmarchicus as in 

 preceding stage, but number of spines at inner margin of basipodite II pes V 2 — 3. The stage III, which 

 varies in size from 2'6— 3 (2"4 — 0-6) mm., the stage II, which varies from 18 — i-g mm. and the 

 stage I, of which I have not examined any specimen, seem only to be distinguished from the corre- 

 sponding stages of Cal. finmarchicus by larger size, as the character found in the pointed lateral 

 corner is wanting. 



Occurrence. Specimens of Calaiins /lypcrbornis have been taken all over the area investigated 

 by the different expeditions as far south as 51^00 L. N. ii°43 L. W., the S/S Thor has '5/o 05 taken 

 a single f?. (St. 82. J t. 1200 M. W.) 



West Coast of Greenland. On the west coast of Greenland it has been found by the Ingolf 

 Expedition from ^^6— 'V7 95 i" ^o samples in the depth of 200 — o fathoms. The stage IV has been 

 found in the greatest number of samples, but the stage V in the largest numbers; of the adult 

 females and stage III only single specimens were found; the youngest Copepodites seem to be wanting: 



Bergendal has at Jakobshavn ^'/s 1890 taken a single f$. 

 Lundbeck has from '9/5 1889. 58°2i L. N. 48°43 L. W. i f?. 



from 23/5 1889. 59°i2 L. N. 52°05 L. W. 3 f?, 3 V. 

 26/5 1890. 57°o8 L. N. 49°o4 L. W. 10 f?, 10 V. 

 Soren Hansen "V? 1885. 59°i4 L. N. 5i°i8L.W. 4 V, 10 IV. 



Eberlein '2/7 1882. Umanakfjord. i f?, 4 (V), i IV. 



Denmark Strait. The Ingolf Expedition has south-west of Denmark Strait (between 62° 

 L. N. and 58° L. N. and between 40"^ L. W. and 26 L. W.) '^6 1895 and from '76—^% 1896 taken 

 4 samples of which 3 contained together 6 f$, 3 respectively 12 V and 9 IV, and only 2 samples 

 containing 3 specimens of stage III. The same expedition has in the Denmark Strait ^^6 1896 taken 5 

 f? and 25 V, 4/5 1895 I f? and ^Vj 1895 3 V - 3 IV. 



The Thor has from '^^ly-^ 1^04 in Denmark Strait in 6 of 7 samples collected 180 f? and 

 104 V, but in 4 of 7 samples only 10 IV. At St 154 "/^ 67°27 L. N. 27°io L. W. the percentage of 

 196 specimens examined was f$ 67 %, V 30 % and IV 3 °/o-
