Mr. Blackwall's Descriptions of new Species of Spiders. 663 



slender, and pale yellowish brown. First pair of legs the longest, then 

 the second, third pair the shortest. Eyes seated on black spots. Abdo- 

 men oviform, glossy, thinly covered with hairs, convex above, projecting 

 over the base of the cephalo-thorax ; it is of a dull yellow colour, with a 

 series of blackish, angular lines, whose vertices are directed forwards, 

 extending along the middle of the upper part, a longitudinal band of the 

 same hue on each side, and an irregular, blackish spot above the plate of 

 each spiracle. A very long, subcylindrical process of a red-brown colour, 

 notched at the extremity, is directed backwards from the sexual organs, 

 with which it is connected. Plates of the spiracles pale yellow. 



The spider from which the foregoing description was taken was captured 

 by Mr. J. Parry at TrafFord, near Manchester, in the autumn of 1837. 



46. Linyphiafurva. Saturate brunnea ferfe nigra; pedibus palpisque flaves- 

 centi-brunneis.

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

Cephalo-thorax oval, convex above, glossy, with an indentation in the medial 

 line of the posterior region. Mandibles long, conical, divergent at the 

 extremity, armed with teeth on the inner surface, and inclined towards 

 the sternum, which is broad and heart-shaped. Maxillse strong, straight, 

 and somewhat quadrate. Lip semicircular and prominent at the tip. 

 These parts are very dark brown, approaching to black, the mandibles 

 and maxillae being the palest. Legs and palpi long, slender, and yellowish 

 brown, the latter being the darker. First pair of legs the longest, then 

 the second, third pair the shortest. The posterior eyes of the trapezoid 

 are the largest, and the anterior ones decidedly the smallest of the eight. 

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

 thorax ; it is thinly covered with hairs, glossy, and brownish black. A 

 small, prominent, cylindrical process is connected with the inferior part 

 of the sexual organs. Plates of the spiracles brown. 



The male is rather smaller than the female, but resembles her in co- 

 lour, and in the relative length of his legs ; these organs, however, have
