CAMBRIDGE O N [Mar. 4, each other than each is from the lateral on its side; those of each lateral pair are bright pearly white, placed a little obliquely, contiguous to each other, and the largest of the eight; those of the fore central pair are the smallest, and nearly, if not quite, contiguous to each other. The legs are rather strong, but not very long; their relative length is 1, 2, 4, 3 ; they are of a clear pale yellow colour, distinctly banded with dark brown and furnished sparingly with hairs and about the usual number of longish black spines. The palpi are similar in colour and markings to the legs ; and from the fore extremity on the upperside of each of the cubital and radial joints is a long, strong, black, slightly curved, tapering bristle ; several smaller ones are also on the digital joint. The falces are long, rather slender, slightly diverging, and similar to the legs in colour. The maxillae, labium, and sternum are dark-coloured, the two former being the lightest. The abdomen is of ordinary form, very convex above and projecting over the base of the cephalothorax; the ground-colour is of a dark leadenish hue, marked with black patches and markings, the sides and upper surface being pretty thickly and rather symmetrically covered with bright white cretaceous spots; some of these form slightly oblique lines on the hinder part of the sides, and others a sort of horizontal cincture on either side of the fore half; others, again, form a broken horizontal band along the lower part of each side. The general character and disposition of the abdominal markings bear a near resemblance to that of L. leprosa (Ohl.) ; but the markings and colours of the cephalothorax distinguish it from that species at a glance, as well as the distinctly annulated legs. A single example was contained in the St.-Helena collection last received from Mr. Melliss. LINYPHIA TRIFIDIDENS, sp. n. Adult male, length 3 lines. This very distinct Spider has the cephalothorax of ordinary form, but rather flattened, and, looked at in profile, it presents a straight line rising gradually from the hinder slope (which is itself very gradual) to the eyes; its colour is yellow; a broad, dark brown, well-defined band runs along each side, converging and almost uniting at the hinder slope, and generally meeting in front above the falces; this band leaves a rather narrow, but distinct, lateral marginal stripe on each side : along the centre of the cephalothorax a tapering dark-brown band runs back from the eyes to the hinder slope, where it ends in a point, and where the junction of the caput and thorax are marked by a strong longitudinal depression. The eyes are similar in their relative size and position to those of L. albimaculata: the clypeus is slightly impressed immediately below the eyes, and rather prominent thence to the lower margin ; its height exceeds half that of the facial space. The legs are long, tolerably strong ; and their relative length is |
