Art oil forekommcr hos os alene i vore Hoifjeldstrakter, 
saaledes paa Dovre (Kongsvold), Filefjeld (Nystuen) og Lom. 
Den er kjendt saavel fra Spitsbergen (Torell) som Grpn- 
land (Kroyer etc.) og det arktiske Nordamerika (Packard), 
hvor den ofte forekommer i store Masngder i gruude Damme. • 
Fain. 2. Branchipodidse. 
294. Branchinecta paludosa, (Mtiller). 
Knn observeret under Expeditionen i et grundt Tjern 
ved Vardo, hvor den imidlertid forekom i store Miengder. 
Arten, som hos os desuden er bekjendt fra Hoifjelds- 
plateauet paa Dovre (Hjerkin og Kongsvold), er udbredt 
til Gronland (Mtiller), det arktiske Nordamerika (= Br. 
gronlandica Verrill og arctica Afters), Sibirien (= Branehipus 
middendorfianus Fischer) og svensk Lapland (Lilljeborg). 
295. Polyartemia forcipata, Fischer. 
Fnnden i store Miengder i et lidet Tjern paa Hoiden 
over Byen Hammerfest. Arten, der hos os alene er ind- 
skrienket til den arktiske Region og navnlig i Dstfinmarken 
er meget almindelig, er forst beskreven af Fischer fra Si- 
birien og ogsaa noteret af Lilljeborg som forekommende i 
svensk Lapland. 
Sulxmlo 3. 
Cladocera. 
Fam. 1. Daphniidae. 
296. Daphnia Schafferi, Baird. 
I det samme Tjern ved Yardp, hvori Branchinecta 
paludosa forekom, fandtes ogsaa denne hos os meget sjeldne 
Daphnia i temmelig betydeligt Antal. Den er forqvrigt at 
mig knn fundet paa 2 andre Lokaliteter her i Landet, 
The species occurs in Norway throughout the Alpine 
tracts alone, thus, on the Dovre chain (Kongsvold), the 
Filefjeld (Nysfcucn) and at Lom. It is known from Spitz- 
bergen (Torell), Greenland (Kroyer and others), and the 
Arctic regions of North America (Packard), where the form 
often occurs very abundantly in shallow ponds. 
Fam. 2. Branchipodidse. 
294. Branchinecta paludosa, (Mtiller). 
On the Expedition, observed only in a shallow tarn, 
near Vardo, where, however, it occurred in great abundance. 
The species which is also known in Norway, from 
the Alpine plateau of the Dovre (Hjerkin and Kongsvold), 
has its range of distribution up to Greenland (Muller), 
the Arctic regions of North America (= Br. gronlandica 
Verrill and arctica Aliers), Siberia (= Branehipus midden- 
dorfianus Fischer), and Swedish Lapland (Lilljeborg). 
295. Polyartemia forcipata, Fischer. 
Met with in great abundance inhabiting a small tarn 
on one of the heights above the town of Hammerfest. The 
species, which in Norway is exclusively limited to the Arctic 
region, and in particular throughout East Finmark, occurs 
with great frequence, was first described by Fischer, from 
Siberia, and subsequently recorded by Lilljeborg, from 
Swedish Lapland. 
Subordo 3. 
Cladocera. 
Fam. 1 . Daphniidse. 
296. Daphnia Schafferi, Baird. 
At Vardo, in the same tarn where Branchinecta pa- 
ludosa was found to occur, we met with this Daphnia — 
very rare in Norway — in comparative abundance. For 
the rest, I have taken .the animal in but two other spots
