the months from November to May in the neighbourhood of Ijergen. 

 In the Arctic sea, Parathemisto is of great impoi'tance as food foi' 

 phinkton eaters. 



I have seen it in the stomach of Gadus vircns both from Bergen 

 and from Vesteraalen; and in March 1897 I noticed it also in the 

 stomach of Gadus callarias, caught near Svolvær in Lofoten. 



Euthenmtu compressa, Goes. 



G. O. Sabs') gives the following distribution for this species: — 

 Davis Strait, East coast of Greenland, Jan Mayen, Hasvig (in West 

 Finmark). Norman'-) states that near Redcar from 10th to 12th 

 of February 1892 there was a vei'y rich Crustacean plankton, which 

 was eagerly sought after by Bissa ttidaetijla. This plankton con- 

 sisted chiefly of Euthemisto compressa which at tliat time was new 

 to the British fauna, and there was also Nematoscelis megalops and 

 Thysanoessa longicaudata. From the Firth of FortJi T. Scott^) 

 refers to this animal as occuring in February and November 1892 

 and in November 1893. 



My observations are the following: — 

 7-2 1897. Sunderø (Vesteraalen), from stomach of Gadus rivens. 

 ^Vi 1899. Kvænangen I, 0—140 m. tow-net. 1 9. 

 22/3 — The Rost sea, 0—700 m. — 



Euthemisto bispiiiosa, Boeck. 



V2 1897. Sunderø (Vesteraalen) from stomach of Gadus virens. 

 G. O. Saks states the distribution of this species as follows: — 

 Greenland, Spitzbergen (?) off Novia Scotia, Sørvær and Hasvig 

 (in West Finmark). 



AmathiUa homati, Fabk. 



AiJuIta, but still more juniores were noticed on '% 1897 in 

 the surface water at Sunderø in Vesteraalen. Also in the sea 

 beyond the belt of skerries (Skjærgaard) off Bergen on -% 1900, 

 — 5 m., young of this species were observed. Development would 

 thus appear to take place in the winter and spilng. 



Cirrlpedia. 



Lepas dnatifera, Linn. 



A splendid bunch on a glass ball (from a tishing not) drifted 

 aslioro in March 1899 on the outer side of Moskeneso in Lofoten. 



Nauplii and Cypris of Cirripedia. 



At certain times larvæ of Cirripedia may be found in large 

 numbers in plankton. Amongst those I have myself noticed I will 

 mention for instance those seen in April 1896 at Bålstad in Lofo- 

 ten, and in April 1897 at Røst. At the latter place, I also on 

 March 24th 1899 noticed a number of these larvæ (Røst I, 0—120 

 m.), and about the middle of April in the same year they were 

 numerous just beyond Vesteraalen, in the Malang Fiord, at Kvæn- 

 angen, the Trold Fioi-d, at Vardø and at Høla near Svolv;pr. 



Ostraeoda. 



While arranging the specimens which have been collected, I 

 have not in every case classilied them according to species, but 

 have grouped them as Conchoecia sp. 



Single specimens have been classified, some by Prof. G. O. Sars, 

 and I have identified some others by reference to Professor G. W. 

 Muller's article in ,,Nordisches Plankton". The following species 

 have been found. 



Conchoecia elegaiis, G. O. Sars. 

 This species is, comparatively speaking, common in the Vest 

 and adjoining fiords, as for instance the Ofot Fiord and Ox Suiid, 

 and is found rather deep down. In the Ofot Fiord on February 

 9th 1899, I took up a quantity of a species of Conchoecia in a 

 closing net, a blueish light gleamed from the forepart of its body. 

 Unfortunately, I was not, then and there, in a position to decide 

 whether the flash of bluelight came from horealis m eleijnns or 

 perhaps fr'om both. 



Conchoecia horealis, G. 0. Sars. 

 j This species too has been observed in the Vest and adjoining 



Fiords, e. g. 



*J2 1899. Skroven I, 0— :300 m. 



73 — Tranø dybet — <i:30 m. 



Vo — The Ofot Fiord I, :S00— 3.50 m. 

 '"A — Oxsund, 450—550 m. 



Conchoecia ohtusata, G. O. Sars. 



Among the specimens which I took at Reine in Lofoten ('Vs 

 1896, 0—130 m.) were a few conchoecia, which Sars declared to 

 belong to this species. 



It is very likely that there were examples of this species in 

 the collection made in 1899. but I can not state this with ceitainty.

hrenda, Baird. 



On April 20th 1899 I took a specimen of this species in 

 the .Jøkel Fiord, and it was by G. 0. Saes declared to be a male. 

 Sparre-Schneider has noticed this species, both in the Kvænang 

 and Malano- Fiords. 



Cladoeera. 



Lradne iiordmanni, Loven. 



.\s far as my experience goes, it appears that Claduccra is 



very seldom seen in the winter plankton on our coasts, and the only 



species I can with certainty say I have noticed is E. nordmanni. 



There were single .specimens in the samples from Lofoten, April 1896.
