CAMBRIDGE O N [June 1, length appears to be 4, 1, 2, 3 ; they are of an orange-yellow colour, and are furnished with hairs and two or three short fine spines; one of these latter, on the outer side, near the middle of the tibia of each of the fourth pair, is much less strong than the corresponding one in E. pictilis. The palpi are short, and similar in colour to the legs; the cubital and radial joints are very short, but of about equal length, the latter being the stoutest; a single, rather upturned, slender bristle issues from the fore extremity on the upperside of the cubital joint; and the radial joint has its fore extremity, rather on the outer side, produced into a short apophysis, whose extremity is obtuse and bifid, or emarginate ; the digital joint is large, and the palpal organs complex, very similar to those of E. pictilis, but the spines and spiny processes are not so strong. The falces are tolerably strong, but not very long ; they are similar to the cephalothorax in colour, and armed with fine teeth on their inner margins, towards the extremity. The maxilla and labium are slightly paler in colour than the falces; but their form is normal. The sternum is heart-shaped, convex, and glossy, of a very deep reddish yellow-brown colour, and thickly clothed with longish hairs. The abdomen is oval, and projects over the hinder slope of the cephalothorax ; its colour is blackish, with a pattern similar to that on the abdomen of E. pictilis, differing slightly, as above observed. About the middle of the upperside are four small reddish impressed spots, forming a quadrangular figure, whose fore side is slightly shorter than the three others ; the surface of the abdomen is thinly furnished with short hairs, and there are two or three rather strongly marked transverse curved folds just above the anal prominence; the spinners are very short and of a pale yellowish hue. Two adult males of this Spider were received from Mr. J. H. Emerton, by whom they were found under leaves at Providence, Massachusetts, U . S. A., in November 1871. ERIGONE PICTILIS, sp. n. (Plate XLVI. fig. 4.) Adult male, length nearly 1| line. The cephalothorax is of a yellow-brown colour, and of ordinary general form, but the caput has its occiput a little elevated, the hinder slope of the elevation, looked at in profile, rounded and gradual, while the front slope is rather abrupt, forming (in profile) with the fore part of the caput a somewhat angular hollow ; the height of the clypeus, which is full, rounded, and slopes a little forward, exceeds half that of the facial space; the upper part of the caput is clothed with numerous bristly hairs directed forward, others of a similar nature occupying the ocular region and directed upwards and rather backwards. The eyes are not very large, nor very unequal in size; they are placed in four pairs, or two transverse rows, of which the hinder one (looked at from the front) is strongly curved, and the foremost much the shortest and nearly straight; those of the hinder row are about |
