A glance at the tables will suftice to convince one that this 

 species is one of the most important plankton copepoda. Propagating 



at any rate I have 

 .Inlv in the fiords 



time is extended over a great part of the year, 

 noticed females with ovisacks from Februaiy t( 

 in the neighbourhood of Bergen. 



Oncæa eonijera. Giesbrecht 



This easily recognized form was only rarely seen in the plankton. 

 It was found in The Vest Fiord. The Jøkel Fiord and the Kvænang. 



Pteropoda. 



Limacina balea. ]\I()ller. 



This species, which may sometimes be found in lai'gc quantities 

 the autunni, wcvc only rarely found in the plankton. Vide tables. 



Appendieularia. 



FritiJlaria horeaUs. LoiniAN. 



What was found of Oikopleam, I iiave not been able to identify, 

 but, on the other hand, the specimens which in the tables are 

 classitied under IrltiUuyia sp. are without doubt F. horenlis. 



Bryozoa. 



Ci/plionautcs. 



The larval form, which at times is tolerably general in the 

 tiords in the neighbourhood of Bergen, can only with certainty be 

 mentioned as having been found by me at one single place, viz. 

 Raftsund. {",'2 1899. Raftsund II, 0—260 m.). 



Chætognatha. 

 Sagitta hiimnctata, Quoy & Gaimard. 



Under tlie designation Chætognatha two species, (rlc. this and 

 th(^ following) will bo found in my tables. 



Meanwhile, howevci', I have noticed sevoi'al places whei'e 5'. 

 hqjunctata has been found, e. g. '7» 1899, Tranødyb, 0—50 m.; 

 -"/a 1899. Henningsvær II, 0—100 m.; -V» 1899, Tysiioi'd I, 

 — 100 m.; '7i 1899, 40 miles NNVV of Gaukværø, 0—100 m. 

 As far as my experience goes, this species on our coast is only found 

 hi the upper layers of water, but SpafMla hamata is almost without 

 exception found in samijlos taken from docp watoi-. The species 

 last mentioned has been found by me in ([uantities in the stomachs 

 of Youni;' ,,sei" caught on the coast nil' liergeu. 



SjiiiilrUa liiimiila. M("iiiU's. 



I have found this si)0cic.s in large ((uantities in samples taken 

 fi'om deep water. Among the many places where it has been found, 

 1 may mention The Vest Fiord, Øxsund, The Ofof Fioid, The Tys 

 Fiord'. The Folden Fiord. The Skjei'stad Fioi'd. S:v. 1 have taken 



it both. 

 Øxsund. 



with townet 



I counted the sjjecimens from 



'/2 1899. Oxsund. 



As before mentioned, this species as a I'ule is found at greater 

 depths, but I can mention one exception. In the Skjerstad Fiord 

 {% 1900, Skjerstad fj. VIII, m.) several large specimens were 

 found swimming about in the surface water. This circumstance 

 may perhaps be accounted for when the peculiar hydrographical 

 character of The Skjerstad Fiord is remembered. The length of 

 the fully developed specimens was 30—35 mm.; while those from 

 Skjerstad Fiord were about 40 mm. 



In samples from The Vest Fiord ('Vs 1899, Tranødyb, 300—400, 

 500—600 m.) there were specimens with eggbags. The hindei'part 

 of the side fin was bent downwards, thus forming a hollow in which 

 the eggs lay tightly pressed together. 



In samples from the same place taken at a depth of 400—500 

 m. there were quantities oi juniores (2—3 mm. I of a chætognath, 

 which most probably was S. hamata. 



Similar young individuals were also found, e. g. in The Tys 

 Fiord (-73 1899, Tysfd. I) in samples taken at a depth af 3()()— 500 

 m. but they were especially numerous in samples taken from a 

 depth of 500—600 and 600—700 m. 



Ctenophora. 



Lulnui 'lufuudthnJam, Fauk. 



Prof. Chux has identitied B. norvcglca M. Saks with this 

 species. Chun writes'): — „Falls die von Mertens (1833) aus der 

 Bering-Strasse beschriebcne B. septentrionalis mit unserer Art iden- 

 tisch ware (was atis dei' Abbildung nicht ohne weiteres hervorgeht), 

 so durfte audi /.'. nifundilndum eine circumpolarc Verbreitung auf- 

 wiesen. " 



This lobate Cteuoi)liorc has been noticed by me in the Jokel 

 Fiord (-"/4 18i)9) as well as in the sea at Hammerfest i-"-'/4 1899). 

 Unfortunately I did not succeed in preserving any specimen. C. 

 VoGT observed this beautiful form in 1861 in Lofoten. 



Anthozoa. 



Amchaadt^ allnda. M. Sahs. 

 Sevei'al spcciiiu'iis of this species were found in the suifacc 

 water of Moskeuslroniinen on March ist 1899. 



') On the whole I have seen several of the hirger plankton turnis in (he 

 triiwl, e. ii. Calanus hi/pcrboreus, Eiichæta norvegica, Parathemisto oblivia, etc.
