Show 264 ON NEW ARACHNIDA FROM KERGUELEN'S LAND. [Feb. 15, rated by an interval of an eye's diameter, and each is also divided by an equal interval from the hinder eye of the lateral pair on its side; the eyes of each lateral pair are separated by a slight interval, not exceeding half the diameter of one of the fore central eyes; the hind laterals are the largest of the eight; and the interval between the fore laterals is equal to about 1^ diameter; the interval between the eyes of the fore central pair is equal to a diameter, the distance of each from the fore lateral on its side being rather greater; and that of each from the hind lateral is equal to the diameter of the latter ; the interval between the fore lateral eyes and the fore margin of the caput is very slight indeed, being less than the diameter of one of the central eyes. The legs are moderately long and strong; their relative length does not differ greatly, being 4, 1, 2, 3. They are of a brownish yellow colour, faintly and imperfectly annulated with dusky brown; the annulations are scarcely perceptible in some examples. They are furnished with spines, bristles, and hairs, some of the latter being at right angles to the different joints ; each tarsus terminates with three curved claws, of which the inferior is m u c h the smallest, and sharply bent downwards. The palpi are similar in colour to the legs; furnished with hairs and a few bristles, and of moderate length and strength. The cubital joint is short and bent; the radial is slightly longer and spreads out gradually on its outer side into a somewhat irregularly shaped prominent but not very large apophysis at its fore extremity ; the digital joint is long and rather narrow, similar in form to that of some species of Tegenaria ; the palpal organs are simple, and have a long curved filiform spine connected with them, and by which they are very nearly encircled; this spine issues from the base of the palpal organs, and curving first round their inner margin terminates on the opposite side. The falces are long, strong, and vertical, prominent near their base in front, and similar in colour to the cephalothorax. The maxilla are similar in colour to the falces; their form has been already described above. The labium has also been described. Its colour is dark blackish brown. The sternum is heart-shaped, similar in colour to the legs, and furnished with hairs. The abdomen is oval, moderately convex above, and does not project greatly over the base of the cephalothorax. It is clothed with hairs, some on the fore part of the upperside being prominent and of a bristly nature. Its colour is brownish yellow mixed with brown and black, a tolerably distinct pattern being visible on the upper-side ; that on the fore half consists of two longitudinal curved rows, each of three irregular yellowish spots, followed (on the hinder half) by a series of alternate yellowish and black angular bars or chevrons, the angles directed forwards; or the hinder half may be described as of a yellowish colour marked with a series of four or six black angular bars, which diminish in size towards the spinners ; the |
