Thorell.] 504 [April 21, 



thorax being of a purer black, with the lateral bands less distinct ; 

 the legs, which have the same markings as in the female, are of a 

 clearer yellowish brown color than in that sex, but darker at the 

 base ; the coxa? are black above and blackish beneath, the thighs also 

 blackish on the under side towards the base; the tarsi are yellowish 

 brown, scarcely black at the extreme apex (as in the male). The 

 palpi are very dark yellowish brown (the tibial joint almost black) 

 with black lines, and the tarsal joint quite black ; the tibial joint 

 is thickly clothed with black hair ; also the other joints are black 

 haired. The patellar joint is somewhat longer than broad, cylindri- 

 cal, the tibial joint scarcely longer than the tibial, but broader, being 

 slightly and gradually dilated towards the apex ; the tarsal joint 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 ele- 

 vated 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 

 outwards 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, downwardly directed black tooth is visible; 

 close to the anterior side of its posterior elevated portion is a trans- 

 verse spine-like costa. The anterior lower part of the bulb shows 

 on the outer side two pale appendages or narrow lobes. The abdo- 

 men has a very distinct narrow band covered with whitish hair on 

 the anterior part of the back ; the belly is blackish. 



?. Length of the body, 6 millim.; of cephalothorax, 3.5 millim.; 

 breadth of cephalothorax, 2.25 millim. ; first pair of legs, 9.5 millim.; 

 second, 8.5 millim.; fourth, 13 millim.; patella and tibia of fourth 

 pair, 3.75 millim. ; tibia, 2.75 millim. 



6. Length of body, 6.5 millim.; of cephalothorax, 3.25 millim.; 

 breadth, 2.25 millim.; first pair of legs, 8.75 millim.; second, 8 mil- 

 lim.; fourth, 11.75 millim.; patella and tibia of the fourth pair, 3.25 

 millim. ; tibia, 2.5 millim. 



The female here described was captured at Strawberry Harbor, 

 July 28th; the male on Square Island, also in July. This species 

 greatly resembles the next preceding, L. 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 quite differ- 

 ent. L. labradorensis is a Pardosa C. Koch, while L. fuscula (and 

 L. furcifera) appear to belong to Leimonia C. Koch.
