The palpi are short and not very strong : the radial and cubital joints are very nearly of equal length ; perhaps the former is slightly the shortest, and has its outer extremity continued in a tapering apophysis, whose extreme point is slightly obtuse and of a deep brown colour, the rest being of a greenish-brown hue; the length of this apophysis is rather less than that of the joint itself. The digital joint is rather large, of an oval form, exceeding in length that of the radial and cubital joints together; the palpal organs are neither very prominent nor complex, consisting of several corneous processes, of a red-brown aud whitish colour. The falces are moderately long and strong, projecting forwards, and a little prominent near the base in front. The maxillee, labium, and sternum are of the normal character, and (with the falces) are of a dark yellowish-brown colour. The abdomen is of a narrow, oblong-oval form ; it is of a black colour, with a somewhat silky bottle-greenish reflection in some positions. It is well clothed with hairs ; and there are four indistinct pale dots, forming nearly a square, near the middle of the upper-side. The spinners are rather long and prominent, those of the inferior pair being the longest and strongest; they are of a blackish colour, tipped with whitish. The spiracular plates are large and of a dull yellowish-brown colour. A single adult male was comprised in Mr. Melliss's collection from St. Helena. Genus C L U B I O N A. C L U B I O N A DUBIA. (Plate XXIV. fig. 3.) Clubiona dubia, Cambr. Spid. St. Helena, Proc. Zool. Soc, Nov. 1869, p. 532. In the former collections received from Mr. Melliss the female only of this Spider was found; in the last collection there were several males and several females also. In size, colours, and general characters the sexes are similar; but the falces of the male are longer, and each has a strong conically formed sharp tooth on the under edge of its inner side, near the extremity. The palpi are moderately long and not very strong. The humeral joint has three distinct and nearly erect black spines near its fore extremity on the upperside, two near together in a transverse line, the third, which is the longest, is a little way behind them. The radial and cubital joints are of equal length ; the former has a small, pointed, tapering, dark red-brown, somewhat tooth-like, corneous-looking apophysis in continuation of its outer extremity, and four , or five longish, bristly, prominent hairs on its inner side; the digital joint is small and of an oval form, not much, if at all, exceeding in length that of the radial joint. The palpal organs are neither very prominent nor complex ; a longitudinally placed corneous process on their outer side has a deep, red-brown, shining margin, |
