Norwegian Sea. The East Greenland Expedition has from "',V, — 'i/e 1900 crossed the Norwefj^ian 

 Sea from 6o''26 Lat. North, 3°io Long. Elast to 69°o6 Lat. N. 612 Long. West. In tlie samples taken 

 with the net F. (F. 1—89) 79 were found containing C.f. but only 5 without any specimen.s. 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 mini her of samples 



(altogether 33 1 in which each 



stage occurreil. 



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 

 (1 — 2 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. iu.st. [F. 51: 4 (V), 20 (IV), 20 (III), 18 (II], 11 (I); F. 52: 

 2(V), 10 (IV), 14(111), 10 (II), 20(I)|. 



In 10 samples taken between 67° L. N. and 69° L. N. (F. 62—81) fj were found, in fairly big 

 numbers (5—10), 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, certainl\- 

 of Cal. fi)ii)iarchicus^ as no Cal. Jiyperborcus was found in this region, were observed. It seems to be 

 probable that propagation took place in this region c. ^4/^ 1900, in a similar way, as Da mas 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 jtuiiores there found are born in the region explored by 

 Dam as, it is at present impos.sible to tell. 



Near Jan Mayen. In the ocean tract pa.ssed by the Danish East Greenland l^xpedition from 

 2% II p. m. 1900 to 'V7 9 a. m. from near Jan Mayen to 74°i5 Lat. North i2°2i Long. A\'est \V. 91 — 

 F\ 243) about 145 samples were found, of which only 4 contained a few specimens of (". /. viz. V. 92 

 =^76 II p. m., F. 96 30/,, 4 a. m. and F. 91 ^s/^ n p. m. with 5 f?, 2 (V), i (III) near Jan .Mayen, and 

 F. 143 •^,'7 8 a. m. 72^30 L. N. 0=41 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 tew 

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

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