Show 392 REV. O. P. CAMBRIDGE ON N E W DRASSIDES. [June 2, it can hardly be confounded, in spite of a certain resemblance in the form of the radial apophysis. DRASSUS MACILENTUS, sp. n. (Plate LI. fig. 16.) Adult female, length 3£ lines. In form, colours, and general structure this species is very nearly allied to Drassus lapidicolens. The colour, however, of the cephalothorax and legs is less suffused with brown, being of a clearer yellow than in that species ; the abdomen is less hairy, and (when in spirit of wine) the upperside is closely marked with slender unsteady yellow lines and spots upon a dark brown ground; these lines fade off into the pale yellowish drab colour of the underside. The falces are less projecting than in D. lapidicolens; and the position of the eyes also differs, chiefly in the nearer proximity to each other of those of each lateral pair ; these are barely an eye's diameter distant from each other, while in D. lapidicolens the interval is quite if not more than two diameters ; the line formed by the eyes of each lateral pair of the latter species is also less oblique than in the one now under consideration, the length of the two lines formed by all the eyes of this species being more nearly equal in leugth ; the eyes of D. lapidicolens are also smaller than those of the present species. The genital aperture is exceedingly small and simple, consisting merely of two small oval blackish-edged openings, placed rather obliquely near each other, their longitudinal diameter running parallel to the length of the abdomen. A single adult female of this Spider was contained in the collection made for me in Bombay by Col. Julian Hobson. DRASSUS CAMPESTRATUS, sp. n. (Plate LI. fig. 17.) Adult male, length 2f lines. The cephalothorax of this Spider is oval, more pointed before than behind; the caput is small, and the lateral constriction where it unites with the thorax is slight; it is of a flattened form and is only a little higher at the thoracic junction than at the eyes, and is thinly clothed with hoary grey hairs ; the normal lateral indentations are indicated by dark brown stripes, which run into a strong marginal band of the same hue, the middle portion of the cephalothorax being of a paler yellow-brown colour. The eyes are rather large, in two almost equally curved rows, the convexity of the curves being directed away from each other, forming an oval figure; the front row is rather the longest, and the eyes which compose it are about equally separated from each other, the intervals being each, as nearly as possible, equal to the diameter of one of the hind central pair; these are of an oval form and placed slightly obliquely. The lateral eyes of the hinder row are rather larger than the central; those of the fore central pair are round and the largest of the eight; they are separated from each other by no more than half of an eye's diameter, and form a line rather longer than that formed by the eyes of the hind central pair. The fore lateral eyes |
