CAMBRIDGE ON SOME N E W [Jan. 21, part being longitudinally wrinkled ; but the pattern described from the female is visible on the upperside, though less distinctly, owing to the yellow ground-colour of the female being replaced in the male by a red-brown similar to that of the cephalothorax; the black patches (in the two males examined) are also of smaller extent, and occupy the four corners of the upperside, leaving a strong well-defined and almost regular Greek cross of a red-brown colour. Four adult females and two males of this pretty species were contained in the Ceylon collection received from Mr. Thwaites in 1871. Subfam. PHILODROMINCE. Nov. gen. A M Y C L E (nom. propr.). Cephalothorax short-oval, the hinder extremity the most pointed, very convex above, almost subconical, caput and thorax being confluent. Abdomen elongate, broader behind than in front, and constricted across the middle, mostly on the sides and upperside. Eyes eight, unequal in size, occupying a large area rather in front of the apex of caput and thorax, and forming two quadrangular figures, one within the other; the outer quadrangle greatly the largest, and formed by the four largest eyes, the inner one situated on the fore margin of the outer one. Maxillee long, slightly hollow both on the inner and outer margins (looked at from above with the Spider flat on its back), rather rounded and enlarged on the outer extremities, and inclined towards the labium. Labium oblong, with the apex somewhat pointed. Leys slender, apparently laterigrade, those of the first two pairs longer than those of the third and fourth, relative length 2, 1,4, 3 ; terminal tarsal claws two. AMYCLE FORTICEPS, sp. n. (Pl. XIII. fig. 6.) Male adult, length 2\ line3. The cephalothorax of this odd and rather Salticiform-looking Spider has the appearance (when looked at in profile) of the hinder part having been trimmed off, the thoracic region being greatly curtailed, while the caput is exaggerated; and the normal grooves and indentations are scarcely visible ; the height of the cephalothorax is more than two thirds of that of the length, its colour is orange-yellow ; and there are a few erect black bristles within the ocular area. The eyes are on tubercles of a paler colour than the surrounding surface ; those of the outer (or largest) quadrangle are rather large, and the tubercles on which they are seated are much the strongest. This quadrangle is rather greater in its transverse than in its longitudinal diameter, and its fore side is rather shorter than its hinder one; on the whole it is not far short of being a square: the inner quadrangle (placed within the larger one) is small, and the four eyes forming it are minute; but its general proportions are not very different from those of the larger one ; its foremost pair of eyes are (when looked at from the front) a little above the straight line of those |
