The spidei* from which the foregoing description was made was found run- 

 ning on a footpath at Oakland, near Llanrwst, in May 1838. 



32. Neriene pulla. Maris cephalo-thorace saturate brunneo ; mandibulis 

 maxillis labioque saturate rufo-brunneo ; sterno brunneo, punctis satura- 

 tioribus ; pedibus palpisque rufescenti-brunneis, nisi in horum articiilo 

 terminali saturate brunneo; abdomine flavescenti-brunneo, punctis nume- 

 rosis strigisque tenuibus saturatioribus. 



Length of the male ^nrth of an inch ; length of cephalo-thorax -^ ; breadth -^; 

 breadth of abdomen ^ ; length of an anterior leg \ ; length of a leg of 

 the third pair ■^. 



Cephalo-thorax oval, convex above, glossy, with slight furrows on the sides, 

 and an indentation in the medial line of the posterior region ; its colour 

 is dark brown. Mandibles strong, conical, armed with a few teeth on the 

 inner surface, and inclined a little towards the sternum. Maxillae power- 

 ful, and inclined towards the lip, which is quadrate. These parts are of 

 a dark reddish brown colour. Sternum heart-shaped, glossy and brown, 

 with very minute spots of a darker hue. Legs reddish brown ; first and 

 fourth pairs the longest and equal in length, third pair the shortest. 

 Second joint of the palpi curved towards the cephalo-thorax ; third and 

 fourth joints short, the latter having a large process, rounded at the ex- 

 tremity, on the outer side, and a smaller one on the inner side ; these 

 joints are of a red-brown colour ; fifth joint dark brown, oval, hairy and 

 very convex externally, concave within, comprising the palpal organs, 

 which are highly developed, complicated in structure, and red-brown. 

 Abdomen oviform, convex above, projecting over the base of the cephalo- 

 thorax ; it is thinly clad with hairs, and of a yellowish brown colour, with 

 numerous minute spots and fine streaks of a darker hue. Plates of the 

 spiracles pale yellow. 



Males of this species, with the palpi fully developed, were taken in June 

 1 836, on rails near Llanrwst. 



33. Neriene gracilis. Nigricans ; pedibus pallid^ rufescenti-brunneis ; palpis 



saturate viridibus.
