gr'oenlandica. The middle light stripe is widened at the front end 

 and divided in the middle. The spot on the front of the abdomen 

 is usually bright and distinct, while the other markings are not con- 

 spicuous. PI. IV, fig. 2. The markings of the legs form longitudinal 

 lines on the upper side, rather than rings. The coxae and under 

 sides of the femora are usually a little lighter than the rest of the 

 legs. The sternum Las a light median mark, that only extends half 

 its length, and sometimes light lines at the sides. A very brightly 

 colored female from the mountains near Laggan (PI. iv, fig. 2a) has 

 the under and outer sides of the femora very light yellow, almost 

 white, and a young female from Labrador has the same colors. 

 Several young females from Triangle Harbor, Labrador, have the 

 abdomen nearly covered with light markings and are generally light 

 colored, like X. concinna Thor., which I believe to be this species. 



The epigynum resembles that of P. groenlandica, but is generally 

 shorter in proportion to its width, and there is great variety in the 

 shape of the middle ridge. PI. iv, figs. 2c?, 2e, 2/*, show epigyna of 

 three females from Bryon Island, Gulf of St. Lawrence, fig. 2/* is the 

 most common form. Fig. 1h is from the light colored female from 

 the Rocky Mountains. Fig. 2c is from the specimen named Lycosa 

 glacialis by Thorell, from Foulke fjord, Greenland. Females of 

 Pardosa hrunnea Em., from Mt. Washington and New England, 

 usually have the form of epigynum shown in fig. 2/*. 



The palpal organs of the three males from Port Llawkesbury, 

 Bryon Island, and from Laggan are like PI. iv, fig. 2g. The males 

 of P. hrunnea have the palpal organs like PI. iv, fig. 2A, with the 

 basal hook much as it is in grmnlandica^ and the end of the tube 

 and other appendages correspondingly longer and straighter. Judg- 

 ing by females alone, I should consider P. brunnea the same as 

 glacialis, but this difference in all the males examined makes their 

 identity doubtful. ^ 



PI. IV, fig. 2^■ shows the epigynum of the type-specimen of X. 

 concinna Thor. It resembles that of glacialis, except at the ante- 

 rior end, where the middle septum seems to be bent inward and 

 forward, so as to give the appearance of one anterior depression 

 instead of two.
