392 REV. O. P. CAMBRIDGE ON NEW DRASSIDES. [June 2, 



it can hardly be confounded, in spite of a certain resemblance in the 

 form of the radial apophysis. 



Drassus macilenttjs, 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 cephalo- 

 thorax 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 inter- 

 val 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 length ; 

 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
