In 1899 juniores were observed in the plankton from January 

 to April inclusive, and during the .same time I have notes of many 

 specimens of females Avith ovisacks. In some of them the bent 

 ovarial tubes were seen to be full of the blueish eggs which shone 

 through the body so that tlie blue ovarial tubes could be seen by the 

 naked eye. In this species too, I noticed two red spots on the 

 ventral side of the genital segment in females. I liave suggested 

 the hypothesis that these are for tlie guidance of tlie males when 

 they deposit spermaphores. 



It has been found on examination in the southern herds that 

 tlie .spawning time for this species also takes place at other times 

 than mentioned above, but I suppose that in the northern fiords 

 the special time for spawning is during tlie first few months in the 

 year, from January to April. 



This species is one of the few jjlankton organisms, which I 

 have found in the stomach of Lofot cod.

 jinia Fiord right up to r^ofoten. I have found it in Gxsund {'"A 

 1899, 0—100 m.) and in Kvænang ('-'A 1.S99, 0— KiO m.) Miiich 

 must be taken as the most northernly place where this species has, 

 up to the present, been observed.

A single specimen of this species was found in a sample from 

 Røst (Lofoten Islands) 'A 1S97, and this was a female.

This species provides a considerable amount of food in our 

 waters for plankton-eating fish. As, however, on the south west 

 coast it is particularly prominent in the summer and autumn months, 

 it was not to be expected that it would often be met with in 

 samples from the northern fiords, which were taken in the months 

 of January, February, March and April. 1 have only noted it 

 from Moskenstream ('Vi 1899, 0— lOo m.). On the contrary it 

 has frequently been referred to as being found in several of the 

 northern fiords in the autumn of 1898 and 1S99 by Dr. Gran.')

 coast at 70" N. for tliis species.

Off tiie coast of Bergen this species is at times so plentiful 

 that it becomes of importance as food for plankton eaters. I have 

 for instance found large (luantities in the stomachs of young „sei" 

 (coal-fish). 



By a look at the accompanying plankton tables it will be seen 

 that this species is very generally distributed also in the northern 

 fiords of Norway in the winter, but it is not seen in large numbers. 



The following table gives the result of examination in this 

 respect of the samples from Oxsund: —
