Mr. Buacxwaut’s Descriptions of new Species of Spiders. 
eyes of the trapezoid are much the largest, and the anterior ones, which 
are placed on an eminence, the smallest of the eight. Mandibles power- 
ful, conical, armed with two rows of teeth on the inner surface, and in- 
clined towards the sternum, which is heart-shaped, glossy, and thinly 
covered with long, erect hairs. Maxillæ strong, straight, and somewhat 
quadrate. Lip semicircular and prominent at the extremity. The man- 
dibles and maxillz are brown, with a faint tinge of red, and the sternum 
and lip brownish black, the latter being dark brown at the tip. Legs 
and palpi long, and of a yellowish brown colour, with brownish black 
bands. First pair of legs the longest, then the second, third pair the 
shortest. Each tarsus in this, as in the other species of Linyphia, is ter- 
minated by three claws; the two superior ones curved and pectinated, 
and the inferior one inflected near its insertion. "The palpi have at their 
extremity a long, slightly curved claw, minutely dentated more than half 
its length from the base. Abdomen thinly covered with hairs, very con- 
vex above, projecting over the base of the cephalo-thorax; it is of a yel- 
lowish brown colour, freckled with small, whitish spots, which are fewer 
in number and more minute on the under side; on the anterior part of 
the upper side are large, brownish black blotches, and on the posterior 
part numerous transverse, curved lines of the same hue, whose convexities 
are directed forwards; the sides are brownish black, with an irregular, 
longitudinal band of yellowish brown, spotted with white, extending 
along the middle. The spinners are brown, and at the base of the 
inferior pair are three confluent, yellow spots, forming a rhomboid. A 
small, cylindrical, semitransparent process is connected with the anterior 
part of the sexual organs, within the external orifice. Plates of the spi- 
racles pale yellow. 
The male bears a strong resemblance to the female, but is rather 
smaller and dàrker coloured than she is; the anterior párt of the cephalo- 
thorax also, on which the eyes are seated, is more elevated. The relative 
length of the legs is the same in both sexes, but their absolute length is 
greater in the male, an anterior one measuring }jths of an inch. Third 
and fourth joints of the palpi short, the former having a long bristle pro- 
jecting from its extremity, in front; the latter, which is the larger, is of
