hairs, glossy, and a|)peais 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 

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

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

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

 noqiie saturate, pedibiis palpisque flavescenti-brunneis paululùm rufo 

 tinctis, horum articulo terminali saturate brunneo ; abdomine nigri- 

 cante. 



Length of the male -^2 th 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 thei-e 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. 

 Maxiliœ 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 maxiliœ 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, witli 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-
