94 ARANEIDEA. 
The palpi are strong and leg-like, and the undersides of the digital and radial joints are armed with two rows 
of strong spines. , 
The falces are powerful, prominent, in profile arched; they have a considerable prominence at the extremity 
on the inner side armed with strong spines. 
The mawille are short, broad, and strong, divergent; at their extremity on the inner side is a distinct 
conical prelongation or prominenee. 
The labium is a little longer than broad at its base, and of a subtriangular form rounded at the apex, where 
(as well as on the front surface of the mayille) on the inner side are numerous short denticular spines. 
The sternum is of a somewhat elongated pentagonal form, broadest behind, and strongly impressed along the 
middle. 
The abdomen is short-oval, of moderate size, rather convex above; the spinners, four in number, are short, 
the upper pair very strong, 4-jointed, the lower pair small and 2-jointed, The spiracular plates 4, and in 
ordinary position.

Tmarus ineptus, sp. n. 
Adult female, length 2} lines. 
The cephalothorax is short, broad, oblong-oval, truncate in front just above the falces; sides dark yellow-brown, 
with pale converging broken lines. The eye-area and clypeus are marked and mottled with yellow-brown 
and whitish, and this is continued in a tapering form to the hinder extremity ; the central longitudinal 
band is constricted at the beginning of the hinder slope, and has a fine prominent pomt there on each side. 
The surface of the cephalothorax is thinly covered with minute tubercles, from each of which issues a 
strong prominent bristle. The height of the clypeus is half that of the facial space. 
The eyes are in the usual position, and occupy the whole width of the caput. Those of the lateral pairs are 
much the largest, the anterior of each pair being the larger of the two. They are seated on large whitish 
tubercular prominences of a somewhat truncated conical form, strongly globose towards the base. The 
fore centrals are the smallest of the eight, and are considerably nearer to each other than those of the hind 
central pair. The interval between those of the fore central pair is equal to that between each and the 
hind central eye opposite to it, and the interval between those of the hind central pair is less than that 
between each and the hind lateral eye next to it. The four central eyes are also on small tubercles. 
The legs are short ; the first pair is slightly longer than the second. The third and fourth pairs are much the 
shortest, and as nearly as possible equal in length. They are all of a pale brownish-yellow colour, broadly 
striped longitudinally with cream-white, and the white bands are marked with roundish chestnut-brown 
spots ; these are most marked on the first and second pairs, of which the fore extremities of the metatarsi 
are marked with a small black-brown annulus. ‘The tibix and metatarsi of the first two pairs are armed 
with spines issuing from slight tubercles; of these spines the chief are arranged in three pairs under each 
tibia and four under the metatarsi, forming two longitudinal parallel rows. All the femora have some 
spines on the upperside. The tarsi end with two curved pectinated claws. 
The palpz are small, short, and similar to the legs in colour. 
The falces are small, short, subconical, and similar in colour to the clypeus. 
The maaille and labiwm are similar to the legs in colour. 
The sternum is cream-whitish, narrowly margined with yellowish-brown. 
The abdomen (looked at from above) is of somewhat subtriangular form; the hinder part is elevated and termi- 
nates in a strong subconical prominence, from the base of which the hinder slope to the spinners is straight 
and rapid. The colour is dull yellowish, marked and mottled with cream-white and brown, the former 
chiefly distributed along the middle of the upperside. It is thinly sprinkled above and on the sides with 
minute deep red-brown tubercles, from each of which issues an erect blackish spine-like bristle. The 
genital aperture is small but of a characteristic form.
