The eyes are rounds and are disposed on the anterior part <rf 

 the cephalo-thorax in two nearly parallel, transverse rows ; the 

 posterior row is rather the longer, and the intermediate eyes, 

 which are the smallest, and nearer to each other than they are to 

 the lateral eyes of the same row, form a square with the inter- 

 mediate eyes of the anterior row, which are much the largest of 

 the eight and black, all the others being diaphanous. Cephalo- 

 thorax oval, convex, pointed before, and thinly covered with 

 hairs : maxillae long, convex at the base, depressed near the 

 middle, enlarged at the extremity, which is obliquely truncated 

 on the inner side and curved towards the lip, which is long, 

 oval, and rounded at the apex : sternum oval, broader in the pos- 

 terior than in the anterior region, and supplied with hairs, which 

 are densest on the margins : legs robust, moderately hairy, and 

 provided with a few sessile spines ; the fourth pair is the longest, 

 the first slightly surpasses the second, and the third pair is the 

 shortest ; each tarsus is provided with hair-like papillae on the 

 under side, and has two curved, pectinated claws at its extre- 

 mity. These parts, with the palpi, are of a yellowish brown 

 colour, the digital joint of the latter and the lip being the 

 darkest. The falces are powerful, conical, armed with one or two 

 very minute teeth on the inner surface, slightly prominent, and 

 of a red-brown hue. Abdomen of an elongated oviform figure, 

 projecting a little over the base of the cephalo-thorax; it is spa- 

 ringly clothed with short whitish hairs, and is of a pale olive- 

 brown colour, reticulated with fine, dull, yellowish white lines ; 

 the sexual organs are minute and reddish brown ; and the spin- 

 ners are prominent, cylindrical, and of a pale yellowish brown 

 colour. 



The spider from which the foregoing description was made 

 was captured in August near Lancaster.
