Mr. Buacxwaut’s Descriptions of new Species of Spiders. 
Eyes placed on black spots on the anterior part of the cephalo-thorax ; 
the intermediate ones form a trapezoid whose anterior side is the short- 
est; the other four are disposed in pairs on the sides of the trapezoid, 
those constituting each pair being seated on a small eminence, and con- 
tiguous ; the posterior eyes of the trapezoid are the largest, and the ante- 
rior ones the smallest of the eight. Mandibles reddish brown, powerful, 
conical, armed with teeth on the inner surface, and slightly inclined 
towards the sternum, which is heart-shaped, rough with long, erect, 
black hairs, and is of a dark brown colour. Maxillæ short, strong, 
straight, and somewhat quadrate, resembling the mandibles in colour. 
Lip semicircular and prominent at the extremity, which is reddish brown, 
the base being blackish. Legs and palpi long, slender, and of a reddish 
brown colour, with blackish brown bands. First pair of legs the longest, 
then the second, third pair the shortest. The palpi are terminated by a 
slightly curved claw. Abdomen pointed at the extremity, very convex 
above, projecting over the base of the cephalo-thorax ; it is thinly covered 
with hairs, and of a yellowish brown colour, freckled with numerous, mi- 
nute, whitish spots; along the middle extends a series of angular lines of 
a brownish black hue, whose vertices are directed forwards, and whose 
extremities, greatly enlarged, form a row of very conspicuous, irregular 
spots on each side of the medial line; several of the anterior angles are 
bisected by a fine, brownish black line; two longitudinal, irregular, 
brownish black bands occur on each side of the abdomen, the upper one 
being connected with the enlarged extremities of the angular lines by 
small, confluent spots of the same hue; a large, brownish black band, 
whose anterior extremity is the broadest, occupies the middle of the ab- 
domen underneath, and comprises a yellowish brown medial line. Sexual 
organs prominent and brownish black, except at the extremity, which is 
flesh-coloured. Plates of the spiracles pale yellow. 
The male is smaller than the female, but resembles her in colour, 
design, and the relative length of his legs; the absolute length of these 
organs, however, is rather greater, an anterior one measuring 3iths of an 
inch. Third and fourth joints of the palpi short, the former, which is the 
larger, having several long, curved bristles projecting from its extremity,
