The spiders considered here were collected by Dr. Francis Harper during the period from May 31 to December 4, 1947, in the vicinity of Nueltin Lake, Keewatin, Canada while on a trip made under the auspices of the Arctic Institute with support from the Office of Naval Research.
A general account of the area and field notes have been given by Harper (1948, pp. 153-184) and Henry W. Fowler has presented a taxonomic report on the fishes (1948, pp. 141-152).
Eleven species of spiders belonging to five families are represented by mature specimens; and juveniles, not determinable to species, add another family.
