Of 5 samples from Jan Mayeii (^s/o i ^- "'• — 5 ^- m-) 4 contained f$ (21 specimens), 5 (V) (34 

 specimens) and 3 stage (IV) (6 specimens only); of 8 day samples 5 (taken 6 a. m. to 11 p. m.) did 

 not contain any specimens, but 3 (12 a. m,— 3 p. m.) contained together 9 f$.

From the ^^/e 10 p. m.— ^7 1900 the East Greenland Exp. has near Jan Mayen collected c. 40 

 samples (F. 90 — 135); 27 day samples (6 a. m. — 7 p. m.) were taken, of which only F. 125 ('/-^ 1912 

 mid-day 7i°3i N. 7°43 L. W.) contained a single f?; of 13 night samples the 4 following contained 

 C. //., and the f^ most abundantly. 



In the ocean tract crossed by the East Greenland Expedition from ^/^ i a. m. to 9/7 12 p. m. 

 between 73° L. N. 4° L. W. and 74° L. N. 11° L. W. 109 samples (F. 136—244) were taken, partly 

 along the ice-edge or among scattered ice. As is easily seen in the following table the adult females 

 are the most frequent; the species is rather scarce at the surface and there is not seen to be any 

 marked difference in its occurrence in different times of the dav. 



That the species was well represented in the greater depth even at locaHties in which it was 

 scarce at the surface is shown by a few vertical hauls (cf. table p. 35).
