tibia scarcely longer than the patella but broader, being slightly and 

 gradually dilated toward the apex; the tarsus is as long as the two 

 preceding joints together, almost pear-shaped. The genital bulb is very 

 high at the base on the under side, this elevated part being obliquely 

 truncated and emarginate on the outer side; it shows in front a large 

 fovea, from which issues a very short and coarse obtuse tooth directed 

 obliquely forward and outward, and bearing at its base a longer and 

 narrower pointed black tooth directed outward and curved backward 

 and downward; this latter tooth lies almost concealed in the fovea; 

 in the middle of the outer margin of the bulb a strong, pointed, down- 

 wardly directed black tooth is visible; close to the anterior side of its 

 posterior elevated portion is a transverse spine-like costa (embolus); 

 the anterior lower part of the bulb shows on the outer side two pale 

 appendages or narrow lobes.

Habitat. — Strawberry Harbor ( 9 ) and Square Island (o'), Labrador. 



The female was captured July 28; the male also in July. "This 

 species greatly resembles P. fuscula; but it is smaller, with the sides of 

 the head more perpendicular, the interval between the two largest 

 eyes is smaller, and the form of the vulva is quite different. P. 

 lahradorensis is a Pardosa C. Koch, while fuscula (and furcifera) appear to 

 belong to Leimonia C. Koch." (Thorell.) 



In general coloration, proportions and' structure, and especially in 

 the structure of the J* palpus, this form is certainl}- very close to 

 modica, and it may prove not to be anything different. It is possible 

 that the differences in the epigynum, which Thorell thinks considerable, 

 may be due to the type of lahradorensis being not entirely adult, the 

 epigynum of immature specimens of modica which I have seen seeming 

 largely to agree with the description of that of lahradorensis given as 

 above by Thorell. 



Pardosa mackenziana (Keyserling), 1876. 



(Sub Lycosa, Verb. z. b. Ges. Wien, 26, p. 621, PI. 7, fig. 7.) 

 Female. — Cephalothorax with a light median reddish-brown band as 

 broad anteriorly as the eye area or nearly so, usually broken a little 

 way back of its anterior end by a transverse dark stripe, behind
