192 ARANEIDEA. 
Eyes as in generic description. The laterals considerably larger than the centrals. 
Palpi short, strong, similar in colour to the falces ; digital joint very short, no longer than the radial, tapering 
and pointed at the extremity. The height of the clypeus is nearly two-thirds that of the ocular area ; it 
is of great width, its sides (looked at from in front) very nearly parallel, and its anterior margin, which 
projects considerably over the base of the falces, is hollowed out, forming a wavy line, a little prominent 
in the middle, but more so at each of the anterior corners. 
The eyes are unequal in size, in two transverse and about equally but not strongly curved lines, the anterior 
row shortest ; the hind-lateral eyes are on a protuberance at the base of a short, strong, horn-shaped 
prominence of the caput; those of the hind-central pair are separated from each other by double the 
interval between each and the hind-lateral eye on its side; the fore-laterals, which are large (and of 
the same size as the hind-laterals), are at the base nearly in front of the horns, and the fore-centrals bear 
the same relative position to the fore-laterals as the hind-centrals to the hind-laterals. 
Legs short, strong, tubercular, but not strongly so. The only specimen examined had lost all its legs but 
land 4; those of the first pair are like the cephalothorax in colour, but the tibiw are darker yellow, 
while the basal half of the femora and the tibie of the fourth pair are pale yellow, the rest of the fourth 
pair being yellow-brown. . 
Falces short, strong, subconical, projecting, and similar in colour to the cephalothorax. 
Mawille like those of Bucranium, and similar to the cephalothorax in colour. 
Labium long, very slender, and of a sharp-pointed tongue shape. 
Sternum oval. 
Abdomen of moderate size, and fitting up fairly close to the thorax; it is of a short, nearly circular form, a 
little truncated in front. The surface is coriaceous, tubercular, and of a mottled yellow-brown, dark 
reddish-brown, and black hue; it is covered with yellowish tubercles (like those of the cephalothorax), 
rather symmetrically disposed (about eight form a marginal row in front), and, like those on the cephalo- 
thorax, each is furnished with a short, strong, prominent spine of a broad somewhat chopper-shape; on 
each side toward the hinder part of the upperside is a largish, oblique, oblong, clear whitish-yellow 
patch. Some accidental adhesive substance obscured the greater part of the underside, concealing the 
genital parts and most of the sternum. The underside seemed to be of a uniform deep brown.

Dysderina plena. 
Dysderina plena, Cambr., antea, p. 143, t. 17. figg. 7, 7 a—d. 
The adult female only was described and figured above (J. c.). I have since come across the male; it resembles 
the female in all general characters, colour, and appearance, but is smaller, measuring 1 line in length. 
The palpi are short; the digital joint is of great size, oval, tumid, and furnished with a few blackish hairs ; the 
palpal organs are, so far as any separate bulb is concerned, conterminous with the joint, and no separating 
edge or fissure could be detected under a strong lens, but from beneath their extremity a small, dark 
brown, corneous process issues, consisting of a slightly bent stem enlarged and divided at its extremity 
into several irregular projections, of which one is sharply bent, blackish, and sharp-pointed ; alongside of 
the stem, and issuing near its base, is a small, brown, tapering, sharp-pointed spine.

ANDRASTA, Simon. 
Andrasta globosa, sp. n. 
Adult male, length rather less than 1 line (about 2 millim.) ; adult female, length 14 lines (2°5 millim.). 
Cephalothorax, legs, and palpi yellow; the tibia, tarsi, and metatarsi of the legs, and the radial and digital 
joints of the palpi ( 2 ) tinged with orange-yellow-brown. 
Legs short, 1, 2, 4,8, furnished with a few longish spine-like bristles on the tibie of the first and second 
pairs.
