joint longer than the third; fifth joint of an elongated oval form, convex 

 and hairy externally, concave underneath, near the middle, comprising 

 the palpal organs, which are moderately developed, not very complicated 

 in structure, with a crescent-shaped process at the extremity, and are of 

 a reddish brown colour. 



In the months of May and June, females of this species, which appears to 

 connect the terrestrial with the semiaquatic Lycosce, may be found under 

 stones in moist situations in the woods of Denbighshire, with their cocoons 

 attached to their spinners. The cocoon is globular, measuring \i\\ of an inch 

 in diameter, and is composed of white silk of a compact texture, surrounded 

 by a narrow zone of a slighter texture ; it contains 40 or 50 spherical, yellow 

 eggs, which are not agglutinated together.

Cephalo-thorax large, convex above, somewhat compressed before, with slight 

 furrows on the sides, and a narrow indentation in the medial line of the 

 posterior region ; its colour is brownish black, but it is clad with yel- 

 lowish brown hairs, which are densest on the anterior part, and the 

 posterior part and sides are marked with white hairs disposed in irregular 

 spots. Four eyes, much smaller than the rest, form a transverse row in 

 front; the other four, situated on the sides and anterior part of the 

 cephalo-thorax, describe a quadrilateral, the anterior ones of which are
