hairs, glossy, and appears to be livid ; but, as the specimen had been some 

 time in spirits when I made the description from it, I cannot speak with 

 certainty concerning its colour. 



I have named the above species in compliment to Miss Ellen Clayton, of 

 Church Town, near Garstang, Lancashire, who discovered it in the neighbour- 

 hood in which she resides. To the zeal of this lady in collecting specimens, 

 and to her kindness in forwarding them to me for description, I am indebted 

 for this and other interesting spiders. 



48. Linyphia obscura. Maris cephalo-thorace mandibulis maxillis labio ster- 

 noque saturate, pedibus palpisque flavescenti-brunneis paululiim rufo 

 tinctis, horum articulo terminali saturate brunneo ; abdomine nigri- 

 cante. 



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

 ■^ ; breadth of abdomen -^ ; length of an anterior leg ^ ; length of a leg 

 of the third pair ■^. 



Anterior part of the cephalo-thorax compressed ; sides marked with slight 

 furrows diverging from the upper part towards the margins ; in the me- 

 dial line of the posterior region there is an indentation. The posterior 

 eyes of the trapezoid are much the largest, and the anterior ones the 

 smallest of the eight. Mandibles conical, armed with a few teeth on the 

 inner surface, and inclined towards the sternum, which is heart-shaped. 

 Maxillae strong, pointed at the extremity, on the inner side, encompassing 

 the lip, which is semicircular and prominent at the tip. These parts are 

 of a dark brown colour ; the cephalo-thorax, which is the darkest, is 

 almost black, and the maxillae are the palest. Legs long, and yellow- 

 brown, with a slight tinge of red ; first pair the longest, then the second, 

 third pair the shortest. The palpi resemble the legs in colour, with the 

 exception of the terminal joint, which is dark brown ; third and fourth 

 joints short, a long, slender bristle being connected with the former, at 

 the anterior part of its extremity ; fifth joint somewhat oval, with a pro- 

 jection on the outer side, and a conical, acute, slightly curved process, 

 directed upwards, at its superior part ; it is convex and hairy externally, 

 concave within, comprising the palpal organs, which are highly deve-
