1905| A NATURALIST IN THE FROZEN NorRTH. 109 
ment is. Small arachnids were found under a stone at Wakeham 
Bay. ‘ 
Humble or Bumble Bees (Bombus) of two species were seen at 
Fullerton at the end of June and in July, flying over the rocks or 
hovering among the flowers of the pinkish red moss-campion 
(Sz/ene acaulis), and specimens obtained. 
Diptera, chiefly of the families Culicidz, CEstride and Muscide, 
are numerous and common in the arctics during the short summer. 
Mosquitoes were very thick and troublesome at Port Burwell, and 
some were caught with the hand on the deck of the vessel. Speci- 
mens of mosquitoes in the larval, pupal, and imago stages were 
also collected at Fullerton. The large larve of a fly which I have 
named the Tooktoo-fly, infest the flesh of the Caribou. Tooktoo 
is the natives’ name for the Caribou. Small dipterous larve were 
_ found in a small dead bird at Cape Isabella, Ellesmere Land, and 
dipterous pupe in the skull of a cetacean at Port Burwell. 
The larve of Caddis Flies were found common at the bottom 
of the fresh-water ponds, where they were readily to be seen, 
crawling along slowly. They were voracious, and those collected 
q kept eating the phyllopods which I had in the same vessel. Their 
cases were composed of bits of leaves. A specimen of Caddis 
Fly (imago) was also found. 
Further reference to insects collected: may be made to a few 
diurnal moths avd caterpillars, to several species of beetles (in- 
cluding aquatic kinds), and to a curiously modified louse, speci- 
mens of which were found on a walrus and on.a seal. 
The time would fail in any effort to describe the various mol- 
lusks, polyzoans, annelids and echinoderms, observed or collected 
during the expedition. The barest allusion can be made to them. 
Pteropods were found, mingled sparingly with medusoids and 
_ctenaphores, moving about near the surface of the sea in harbours; 
and specimens representative of the two sub-classes, viz : Gymno- 
somata and Thecosomata, into which those mollusks are divisible, 
obtained. The species found belonging to the latter named divi- 
sion are popularly known as ‘‘ black-berries.’”’
