CAMBRIDGE ON SPIDERS [Apr. 20, palpal organs, which are rather simple in structure, are surrounded on their outer side by a long, strong, corneous, spine-like process, which originates at their centre, and whose obtuse extremity projects beyond the extremity of the digital joint. The abdomen, looked at from above and behind, is elongated narrow oviform, more or less pointed at its posterior extremity ; seen in profile, the normal hinder part is produced into a long, slightly curved, tapering prolongation, the spinners being generally nearer to the fore extremity of the abdomen than to the point of elongation. The female resembles the male in colours, excepting the legs, which are of a uniform pale whitish yellow, the palpi being black-brown ; the abdomen also is shorter, but very broad at its fore extremity. It is with some hesitation that I have described this Spider as an Argyrodes. Numerous examples of both sexes were included in Mr. Thwaites's Ceylon collection.
