From the following list it seems to be fairly safe to conclude that the C. f. in the month of 

 September is more common at night than in the day time at the surface, and that the stage IV— V is 

 the most common. In no sample I have examined more than 30—40 specimens; in the few ones 

 containing that number the percentage of the stage IV — V was greatest. Only a single fullgrown 

 female was found in a day sample.

For drawing any conclusion from the material from the Ingolf and the Thor Exp. at the 

 present time the material is too scanty. But it can not be denied that the percentage of mature spec- 

 imens is bigger in the August-June samples, and that propagating takes place about the month of 

 June, as fullgrown males or females with spermatophores were found l6 /e 1892 (Lundbeck Dyrefjord), 

 c. 2 °/ 5 1895 and 2 % 1904; no males were found September 1900. 



South of Iceland. In the Atlantic south of Iceland from about 28 Long. W. to the Faeroe- 

 Channel, and as far South as 6o° Lat. North, the Ingolf Exp. has I2 / 5 — 16 / 6 1895—96 taken about 55 

 samples containing C.f., and in August 1895— 1896 about 10 samples.
