Labium of a somewhat triangular form, broader in the middle than at its base, aud pointed at the apex. CHORIZOOPES FRONTALIS, n. sp. (Plate XLIV. fig. 6.) Female adult, length 1| line. The general form and structure of this Spider have been sufficiently described above. The caput has the occipital portion prominent on either side, and a depression where it joins the thoracic part; the normal furrows and indentations are obliterated owing to the abnormal development of the caput, which usurps almost the whole cephalothorax. The cephalothorax is sparingly clothed with pale grisly hairs of a more or less dark yellow-brown colour; the region of the occipital prominences being palest. The eyes do not differ greatly in size : the upper ones of the central quadrangular group are the largest, and those of the lateral pairs the smallest of the eight; the eyes of each of these latter pairs are nearly contiguous, and of a pearly white colour ; the others are darker. The legs are of a pale yellow, banded with yellow-brown, and are furnished sparingly with short hairs. Palpi small, short, furnished with short hairs and a very fine, black terminal claw. Falces large and strong, rather prominent in front and on the sides, and curved when looked at from before; towards the inner extremity of each is a prominence with a curved margin armed with a sort of comb of close-set longish teeth ; the colour of the maxillee is a pale yellowish brown ; that of the labium and sternum being darker. The abdomen is sparingly clothed with very short hairs; it is of a short-oval form and very convex above, bluff and abrupt behind, where it has four, small, bluntish or subconical eminences, arranged in a transverse diamond shape, spanning the whole width of the abdomen ; it does not project over the base of the cephalothorax; and its colour is a dull yellowish with a brown tinge, marked with deep black-brown and white, forming a regular pattern, difficult to describe and best seen in the figure; two small white spots (followed by several more minute ones) are rather conspicuous on the upperside; between the spinners and each of the lateral eminences, and not far from the former, is a large, conspicuous, round, black blotch. The epigyne and the orifices of the spiracles are of a deep red-brown colour; the spinners are short, six in number, and not very strong nor conspicuous. Adult females of this Spider were contained in collections of Spiders from Ceylon, in 1869, both from Mr. Nietner and Mr. Thwaites. I have included it in the family Epeirides, with Spiders of which it is evidently connected, though in the form of the maxillae and labium it bears strong affinity to the Theridides ; in whatever family, however, it may finally be placed, there seems to be no |
