either side, is a short, ohlique, faint line directed backwards. Six small, dull-brown spots 

 in three transverse pairs, also form a long rectangle on the fore-half, the foremost side of 

 the rectangle being rather shorter than the hinder one. The intermediate pair of these spots 

 is (as is usually the case) nearer together than the foremost pair. The spinners are toler- 

 ably long, but not very strong; those of the inferior pair are rather the longest and strongest. 

 The genital aperture is small, and of a transverse, oblong-oval form, margined with deep 

 red-brown.

12. DRASSTJS LAPSUS, sp. n., PL II, Fig. 11, ? . 



Female (not quite adult) : length rather over 3^ lines. 



Although not adult, this spider has sufficiently characteristic specific marks to entitle it 

 to description. 



It resembles Drassus involutus very nearly in colours, but the relative position of the eyes 

 is quite different. 



The cephalothorax is oval, shorter than that of D. involutus, and constricted laterally 

 at the caput ; it is of a pale yellow-brown colour, pretty thickly clothed with short greyish 

 pubescence. 



The eyes are in two transverse rows ; the hinder' row slightly curved, the front row 

 shortest and less curved than the hinder one ; the convexity of the curves is directed back- 

 wards ; the height of the clypeus does not exceed, even if it quite equals, the diameter of 

 one of the fore-central eyes ; those of the hind-central pair are oval, oblique, and very near 

 together, though separated by a distinct interval, and each is separated from, the hind-lateral 

 on its side by an interval equal to the diameter of the latter ; those of the fore-central pair 

 are nearly a diameter's distance from each other, each being very nearly, if not quite, 

 contiguous to the fore-lateral on its side ; those of each lateral pair are placed obliquely, 

 and are separated by rather less than the diameter of the hind-lateral eye ; the four central 

 eyes form a regular quadrangular figure, whose longitudinal diameter is considerably greater 

 than its transverse one. 



The legs are strong, and moderately long ; their relative length is 4, 1, 2, 3. They are 

 slightly lighter-coloured than the cephalothorax, and are furnished with hairs (some of 

 these are of a greyish hue), slender bristles, and spines; these last are tolerably strong, 

 not very long, and almost entirely confined to the tibiae and metatarsi of the third and 

 fourth pairs, whereon they issue from small red-brown tubercles, on the upper, as well as the 

 under, side of the joints ; the only spines on the legs of the first and second pairs are one or 

 two longish ones of a bristle-like nature on the upper side of the femora, and a single short 

 strong one on the under side, close to the hinder extremity of the tibiae of the second pair ; 

 there is a small black claw-tuft beneath the two terminal tarsal claws, and a thin scopula 

 beneath the tarsi and metatarsi of the first and second pairs. 



The palpi are similar in colour to the legs ; the digital joint is longer than the radial, 

 and has, besides hairs and bristles, a few stoutish spines. 



The falces are short, and not particularly strong; they are directed a little for- 

 wards, and are of a reddish yellow-brown colour, with some prominent black bristles in 

 front.
