living forms.” Now these crustaceans, found during the Expedi- 
tion, are free-living and comparatively highly organized kinds. 
Furthermore, their occurrence together in the same pond so cor- 
responds with a somewhat similar condition of things which Sars 
observed in Norway, that I quote what he says: ‘‘ The only place 
where I have met with this form [Dzaptomus bacillifer| is in the 
farthest north of Norway, at Vard6, Finmark. It occurred here 
rather abundantly in a shallow tarn situated close to the town. In 
the same tarn the arctic Phyllopod Lranchinecta paludosa, was 
very common, and the water was moreover peopled with large 
shoals of Daphnia magna.” 
Some conception of the conditions in which those remarkable 
copepods and phyllopods live and move, may be gathered from 
the following quotations from my manuscript notes. 
‘* Walked over beyond the first pond, intending to find the 
Opening in the second, but, owing to a blizzard, could not find 
even the pond. Had on returning to guide myself by the sun 
which dimly shone through the clouds and snow-drift, and at 
length saw the house which had been built for the Mounted Police, 
and so was enabled to make my way back to the vessel. My ears 
and nose were frozen. These facts are merely introduced because» 
such being the circumstances under which copepods were looked 
tor that day, some of the conditions under which they were to be 
sought are thus shewn. Of course they were not to be found, but 
I knew that under the ice they were swimming about as usual.”’ 
This was on the 11th November. 
Of isopods collected were specimens of the Salve Bug (4ga 
psora) found on cod-fish, and specimens belonging to the families 
Idotheidz and Arcturidz. Amphipods were exceedingly numerous 
at Jeast in individuals, and were found in the sea or along the 
beach almost anywhere, some of the species being very closely 
allied. Specimens of Cirripedes or Barnacles, of the genus 
Balanus were found ; but the Crustaceans are two numerous and 
require working out, to say more about them just now. 
Of Arachnids, spiders of different kinds and sizes were found, 
under stones or moving over the ground at Nachvak, Eric Cove, 
Fullerton, and at North Devon Island. Very tiny arachnids (just 
perceptible) were found at Beechy Island, where Franklin’s monu-
