there is a prominent obtuse process, and between these processes 

 there are the extremities of two others; the colour of these 

 organs is dark brown, red-brown, and pale yellow intermixed. 

 The convex sides of the digital joints are directed towards each 

 other. 



Epe'ira rapax. 



Length of the male /^nds of an inch ; length of the cephalo- 

 thorax ^ ; breadth ^ ; breadth of the abdomen § ; length of an 

 anterior leg -*-£ ; length of a leg of the third pair £ . 



The four intermediate eyes, which are seated on a frontal 

 prominence of the cephalothorax, are nearly equal in size, and 

 almost form a square, the two anterior ones being slightly wider 

 apart than the posterior ones ; the eyes of each lateral pair are 

 placed on a tubercle, in a horizontal line, and are separated by 

 a small space. The cephalothorax is compressed before, rounded 

 on the sides, somewhat pointed in front, convex, glossy, and has 

 a large indentation in the medial line ; it is thinly clothed with 

 pale yellowish hairs, and is of a reddish-brown colour, with a 

 broad brown band extending along each side, whose margins are 

 somewhat sinuous. The falces are conical, vertical, and armed 

 with a few teeth on the inner surface ; the maxilla? are short, 

 straight, and enlarged at the extremity, and the lip is semicir- 

 cular, but somewhat pointed at the apex. The colour of these 

 organs is brown, their extremities having a brownish-yellow hue. 

 The sternum is heart-shaped, with minute eminences on the 

 sides, opposite to the legs ; its colour is yellowish-brown, a few 

 obscure dark brown streaks passing from the lateral margins to 

 the medial line. The legs are robust, provided with hairs and 

 spines, the latter being strongest and most numerous on the 

 inferior surface of the somewhat enlarged tibiae of the second 

 pair, and there is a short spine-like process at the extremity of 

 the coxae of the first, third, and fourth pairs, on the under side ; 

 the first pair is the longest, then the second, and the third pair 

 is the shortest ; each tarsus is terminated by claws of the usual 

 number and structure : these limbs have a brownish-yellow hue, 

 and are marked with dark brown annuli. The palpi are short, 

 and of a brownish-yellow colour, a brown transverse bar occur- 

 ring near the middle of the digital joint ; the cubital is smaller 

 than the radial joint, and has a long bristle in front ; the radial 

 joint is protuberant on the inner and outer sides, and is supplied 

 with long hairs; the digital joint is oval, with a process at its 

 base, curved outwards, whose dark red-brown obtuse extremity 

 is glossy; it is convex and hairy externally, concave within, 

 comprising the palpal organs, which are highly developed, pro- 

 tuberant, complex in structure, with a large, prominent, curved,
