COPEPODA 



It is worth noticing that a fo* was found between 50 — 25 fathoms. In this connection it may 

 perhaps be of some interest that Johannes Petersen "/ 7 1901 73 Lat. N. 8° Long. E. caught a 

 big sample consisting almost exclusively of C.f.: the proportion between the stages was the following: 

 f? 52%; V 42-5%, IV 3%, HI 1%, II 0-50/0, I 1%. 



Jan Mayen to East Greenland. From 9/ 7 10 a. m. to r 7/ 7 5 a. m. taken in the sea north-west 

 and west of Jan Mayen between 74°28 Lat. N. i5°03 Long. W. and the coast of East Greenland at 

 70°29 Lat. N. 2i°2i Long. W. I have examined 13 samples (F. 244 — 262), of which only 5 contained 

 C.f. viz. St. VI in 3 samples, IV in 1, II, in 1, I in 1. 



East Greenland. The East Greenland Exp. has, near the coast of Greenland, taken some samples 

 containing C.f. in vertical hauls, viz.

On the voyage home between Forblas Fjord,*Antarctic harbour, and 70 L. N. 18 L W. from 

 3 % 9 P- m - to 2 /° 9 a - m - I 9 00 the East Greenland Expedition collected 20 samples (F. 265 — 278), of 

 which 12 night samples contained C. f in different stages, while 4 day samples only contained a few 

 specimens (St. I— II), and the remaining 4 nauplii only.

The vertical hauls show that stages IV — V of C.f. are fairly frequent in the month of July. 

 As no Cal. hyperborens were found in any of the samples, and as the~younger stages of Copepodites of 

 C.f. were common, there is every reason to regard the nauplii and eggs found in large numbers all 

 over the surface as belonging to the same species. Accordingly there is no reason to doubt that an 

 important locality for the propagation of C.f. is sometimes found in this region. The few samples 

 and the small number in which the f$ were found suggest that the f$ — o* are either exstinguished 

 or living in deeper strata,
