4h Canadian Arctic Expedition, 1913-18 
the inner side extending a little over the tarsus (PL I, fig. 5). Seen from the 
side the tibia is wider than long (PI. I, fig. 6). The tarsal hook is much like that 
of longisetosus, with two short and stout curved teeth at the end and a narrow, 
long base on which are several hairs and close to the tarsus three long bristles 
slightly serrated toward the end somewhat like the bristles in longisetosus and 
armatus (PI. I, fig. 6). The epigynum has a middle lobe widened at the end and 
covered at the base by two depressions divided by a narrow ridge. At the sides 
of the epigynum are two thickened spots with hairs directed inward (fig. 7). 
Localities: One male and two females from Cockburn point, Northwest 
Territories, September 26, 1914. Four females and one immature male from 
Bernard harbour. Dolphin and Union strait, Northwest Territories, June 27. 
1916. 
Tmeticus brunneus Emerton.^ 
Nome Alaska, August 25, 1916. Originally described from the White 
mountains, New Hampshire, at 4,000 feet elevation. 
Microjieta maritima, n. sp. 
Less than 2 mm. long, and dull grey with paler legs. The mandibles are 
thickened at the base and narrowed toward the point, with two small teeth 
where the narrowing begins (PL I, fig. 8). The male palpi are, as usual in this 
genus, large, and the tarsus angular. It has a small process at the base and 
the middle is extended and flattened into a keel bent inward on the outer side. 
This shows plainly from above or below when the palpus is curved in the natural 
position, (Pl.I, fig. 10). The tarsal hook is wide in the middle and turned abruptly 
upward at the point, as in olivacea (PL I, fig. 9). 
Locality: Cockburn point. Dolphin and Union strait. Northwest Terri- 
tory, September, 1914, under stones. 
Microneta crassimanus Emerton.^ 
Nome, Alaska, August 1916. Originally described from the White moun- 
tains, New Hampshire, at 4,000 feet elevation. 
Epeira patagiata Clerck (1757.) 
Nome, Alaska, August 25, 1916. The most common round-web spider 
throughout Canada, the northern United States, and the north of Europe. 
Dictyna. 
Several immature specimens were found under stones along the shore 
at Bernard harbour. Northwest Territories, June and July, 1915. They are 
probably Dictyna hafuif era Thor., 1872, described from Greenland and among the 
spiders from the " Danmark Expedition " to northeastern Greenland, 1906-8. 
Lycosa pictilis Emerton.^ 
Several specimens of this bright-coloured spider, including two adult males, 
were found at Bernard harbour, Northwest Territory. It is common on mount 
Washington, New Hampshire, from 5,000 to 6,000 feet elevation, and has been 
found on the coast of Labrador at Hopedale. The Tarantula exasperans 
Cambridge, from Discovery bay, latitude 81° 44', is possibly this species. It 
is described and figured by Cami3ridge in ' The Annals and Magazine of Natural 
> Conn. Acad. 1882 and Conn. Acad. 1909.
