874 Mr. J. Blackwall on newly discovered Spiders 
thorax ;4,; breadth ;1,; breadth of the abdomen +; ; length of 
an anterior leg 1; length of a leg of the third pair 4. 
The cephalothorax has a short, broad, somewhat oval form ; 
it is convex, prominent and rather pointed in front, depressed at 
the base, and has two furrows on each side directed obliquely 
upwards ; it is clothed with short yellowish-white hairs, and its 
colour is yellowish brown, the medial line and anterior margin 
being the palest. The eyes, which are very unequal in size, and 
seated on brown spots, are disposed on the sides and anterior 
part of the cephalothorax in two transverse curved rows ; those 
of the posterior row, which is much the longer, and has its con- 
vexity directed forwards, are much larger than those of the 
anterior row, the lateral eyes, seated on bold conical tubercles, 
being rather the largest; the eyes of the anterior row, whose 
convexity is directed upwards, are situated high above the frontal 
margin, the two intermediate ones are placed very near to each 
other on a minute tubercle, and the lateral ones are not very 
conspicuous, being the smallest and lightest-coloured of the 
eight ; the lateral eyes of both rows are separated by a very wide 
interval. The falces are short, subconical, and vertical; the 
maxille are powerful, and greatly enlarged at the extremity, 
which is protuberant on the inner surface ; the lip is triangular, 
and the sternum is oblong heart-shaped, with small eminences 
on the sides opposite to the legs. These parts are of a dull 
brownish-yellow colour, the sternum, which is the darkest, 
having its extremity and lateral margins of a dark-brown hue. 
The legs are very unequal in length, the first pair bemg much 
the longest and most robust ; the second pair is longer than the 
fourth, and the third pair is the shortest; they are provided 
with hairs and sessile spines, the latter being the longest and 
most numerous near the base of the tibia of the anterior pair on 
the inner side, and a calamistrum occurs on the upper surface of 
the metatarsus of each posterior leg; these limbs have a dull 
brownish-yellow hue, and, with the exception of the tarsi, are 
more or less marked with dark brown on the inner surface. 
The palpi resemble the legs in colour, but are not marked with 
dark brown ; the humeral joint is slightly curved upwards; and 
the radial, which is longer than the cubital joint, is oval, and 
supplied with some long bristles at its pointed extremity; the 
digital joint is large, of an oblong-oval form, convex and clothed 
with coarse hairs externally, and concave within ; connected with 
this concavity are the very highly developed and complex palpal 
organs, whose broad prominent -base, though curved abruptly 
downwards, extends to the articulation of the humeral with the 
cubital joint; a remarkably long, black, filiform spime passes 
under their margin along the inner side, and curves round the
