COPEPODA 



Norwegian Sea. The East Greenland Expedition has from '9/ 6 2 4/ 6 1900 crossed the Norwegian 

 Sea from 6o26 Lat. North, 3io Long. East to 6a, o6 Lat. N. 6i2 Long. West. In the samples taken 

 with the net F. (F. 189) 79 were found containing C.f. but only 5 without any specimens. In addition 

 to these, 5 samples, taken with a closing net and 6 samples with net A and B were taken. The pro- 

 portion between the different stages in 39 samples from the whole region which were examined in 

 this respect was a follows.

The number of samples 



(altogether 33) in which each 



stage occurred. 



No males were found at the surface in the explored region. As I have unfortunately not 

 examined the proportion between the stages in all the 79 samples, and have not with security classified 

 the larval stages, the following remarks are set forth with due reservation. In the more southern part 

 of the region (to 64 N. F. 38) the stage IV V were found in 14 samples of 16, the f ? only in 4 

 (12 specimens) [F. 27: 10 (V), 6 (IV); F. 29: 8 (V), 16 (IV)]. In a few samples (between 64 N. 65 N.) 

 the younger stages were well represented f. inst. [F. 51: 4 (V), 20 (IV), 20 (III), 18 (II), n (I); F. 52: 

 2(V), 10 (IV), i4(III), io(II), 20(1)]. 



In 10 samples taken between 67 L. N. and 69 L. N. (F. 6281) f? were found, in fairly big 

 numbers (510), but only in a single one of these (F. 64 6f$; 2 (V) i (IV)) stage IV V were found and 

 in another stage I II (F. 66 2 f ? 5 (II), 15 (I)); in the latter sample as well as in most of the ten 

 mentioned above and in several others'often large numbers of eggs and larval stages of Calanus, certainly 

 of Cal. finmarchicus, as no Cat. hyperboreus was found in this region, were observed. It seems to be 

 probable that propagation took place in this region c. 2 t/ 6 1900, in a similar way, as Damas has 

 found out with a more southern and eastern region. Whether the propagation between 62 67 Lat. N. 

 has taken place at an earlier date, or if the juniores there found are born in the region explored by 

 Damas, it is at present impossible to tell. 



Near Jan Mayen. In the ocean tract passed by the Danish East Greenland Expedition from 

 28 / 6 ii p. m. 1900 to 9/ 7 9 a. m. from near Jan Mayen to 74i5 Lat North i22i Long. West (F. 91 

 F. 243) about 145 samples were found, of which only 4 contained a few specimens of C.f. viz. F. 92 

 28 / 6 ii p- m., F. 96 3<y 6 4 a . m . an( j p_ 9I 2 8/ 6 ZI p m w i t h ^ fo^ 2 (V), i (III) near Jan Mayen, and 

 F. 143 2 / 7 8 a. m. 723O L. N. o4i L. W. i f ?. In the samples F. 153 243, which were taken between 

 scattered ice or along the ice-edge no specimens of C.f. were observed, but 17 samples with a few 

 specimens of C. hyperboreus. A few vertical hauls in the region near Jan Mayen show that the fauna 

 of C.f. in deeper waters was probably richer.
