CAMBRIDGE O N [[Mar. 16, of the eight, dark-coloured, indistinct, and seated contiguously (or nearly so) to each other at the extremity of the lower segment of the caput; the longitudinal diameter of the ocular area is greater than its transverse one. The legs are moderately long, slender; and their relative length appeared to be 4, 1, 2, 3; they are furnished with inconspicuous hairs, and a very few slender erect bristles on their uppersides; the colour of the legs is yellow. The palpi are rather long, slender, and their colour is similar to that of the legs ; the cubital joint is long and slightly clavate: the radial joint is short, with its fore extremity, rather towards the outer side, produced into a fine, tapering, pointed, almost straight apophysis; the length of the joint with its apophysis is about half that of the cubital joint; the digital joint is rather small, and of ordinary form ; the palpal organs are neither very prominent nor complex ; in close contact with them, and at their extremity, is a small circularly curved sharp filiform spine. The falces, maxilla, and labium are rather lighter in colour than the cephalothorax, but present nothing unusual in form or structure. The sternum is of ordinary form, and its colour is dark black-brown. The abdomen is of a short oval form, very convex above, and of a pale, dull, straw-yellow colour, with a large dark-brown oval patch on the fore part off the upperside ; and it is sparingly clothed with short inconspicuous hairs ; the spinners are rather larger than usual, but perhaps they may have been accidentally protruded. The adult female is rather larger than the male, but resembles it in colours and general characters; the caput, however, wants both the eminence and prominence of that sex, being merely of the ordinary form, with the occipital region slightly convex and rounded, and the clypeus prominent or, rather, projecting forwards. The genital aperture is somewhat horseshoe-shaped, and has within its opening some small processes, which, when looked at in profile, give it a rather prominent appearance. A n adult example of each sex was sent to m e in July 1871, by M . Simon, by w h o m they were found in the neighbourhood of Paris; it is allied to E. trifrons (Cambr.) ; but the pale colour of the abdomen distinguishes it at a glance, besides the marked differences in the form of the caput and structure of the palpi. ERIGONE CAPITO (Westr.). (Plate XXVIII. fig. 18.) Adult male, length 1| line. The colour of the cephalothorax of this rare and remarkable Spider is a deep shining brown ; the legs are orange-yellow, rather long, moderately strong, and furnished with hairs only; the palpi are similar in colour, except the digital joints, which are dark brown ; and the abdomen is black. The fore part of the caput has a strong elevation, and is divided into two segments-the lower one (comprising the fore part of the caput proper) prominent and rather produced forwards, the upper |
