Mr. BiackwaLv'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. Linyphia furva. Saturaté brunnea ferè nigra; pedibus palpisque flaves- 
centi-brunneis. 
Length of the female $th of an inch; length of cephalo-thorax 3; breadth 
as; breadth of abdomen 3; length of an anterior leg t; length of a 
leg of the third pair + 
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. Maxillæ strong, straight, 
and somewhat quadrate. Lip semicircular and prominent at the tip. 
These parts are very dark brown, approaching to black, the mandibles 
and maxillæ 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
