Length of the female ^ of an inch j length of the cephalo- 

 thorax -5-, breadth -^ ; breadth of the abdomen J-. 



The cephalothorax is compressed before, rounded in front and 

 on the sides, slightly convex, glossy, with a large indentation in 

 the medial line of the posterior region ; it is of a yellowish-brown 

 colour, with a red-brown band parallel to each lateral margin, 

 and another in the medial line, whose greatly enlarged anterior 

 extremity comprises the whole of the cephalic region. The 

 falces are powerful, conical, vertical, very convex in front, glossy, 

 armed with teeth on the inner surface, and have a red hue tinged 

 with brown. The maxillse are straight, enlarged at the extremity, 

 which is somewhat angular on the outer side, and of a brownish- 

 red colour. The lip is semicircular and prominent at the apex; 

 and the sternum is heart-shaped, with prominences on the sides, 

 opposite to the legs. These parts are of a dark-brown colour 

 tinged with red, the apex of the former and the lateral margins 

 of the latter having a yellowish-red hue. The legs are long, 

 slender, provided with hairs, and of a brown colour, the base of 

 the femora being the palest ; their relative length could not be 

 ascertained, as they were detached and mutilated; but, judging 

 from the relative size of the coxse, the first pair should be the 

 longest, then the second, and the third pair the shortest. The 

 palpi are long, slender, of a brownish-yellow hue, and have a 

 slightly curved, minutely pectinated claw at their extremity. 

 The eyes are seated on black spots on the anterior part of the 

 cephalothorax; the four intermediate ones nearly form a square; 

 the two anterior ones, which are placed on a slight protuberance, 

 are rather nearer to each other than the posterior ones, which 

 are the largest of the eight; the eyes of each lateral pair are 

 seated near to each other on a small tubercle, the posterior one 

 being the smallest. The abdomen is subcylindrical, tapering 

 somewhat to the extremity, which is obtuse, slightly curved 

 upwards, and extends beyond the spinners ; and there is an ob- 

 tuse protuberance on each side of the anterior extremity, which 

 projects over the base of the cephalothorax; the upper part and 

 sides have a silvery lustre, with a slight golden tinge, and on
