thorax in two transverse rows; the four intermediate ones 

 nearly form a square, the two anterior ones, which are seated 

 on a protuberance, and are rather nearer to each other than the 

 two posterior ones, being the largest of the eight ; the eyes of 

 each lateral pair are placed obliquely on a prominent tubercle, 

 and are separated by a considerable interval. The cephalo- 

 thorax is long, somewhat convex, particularly in the cephalic 

 region, truncated in front, compressed before, moderately rounded 

 on the sides, which are marked with furrows converging towards 

 a transverse pair of indentations in the medial line of the poste- 

 rior region, and has two conical glossy eminences placed trans- 

 versely near its middle ; it is of a dark-brown colour, which is 

 almost concealed by a covering of short, adpressed, white hairs 

 having a silvery lustre. The falces are powerful, conical, ver- 

 tical, glossy, convex at the base, in front, and armed with teeth 

 on the inner surface ; the maxillae are short, strong, and greatly 

 enlarged and rounded at the extremity ; and the lip is somewhat 

 oval. These parts are of a very dark brown colour, the extremity 

 of the maxillae, the apex of the lip, and a line extending along 

 the middle of the latter having a dull-yellow hue. The sternum 

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

 a somewhat pointed one opposite to the base of the lip ; it is of 

 a bright yellow colour, with a large, irregular, transverse dark- 

 brown mark in the middle, and narrow lateral margins of a 

 similar hue. The legs are very long, slender, provided with fine 

 spines and hairs, the latter being the longest and densest on the 

 inferior surface and sides of the tibise of all the legs except those 

 of the third pair ; they are of a yellow colour ; a broad annulus 

 near the middle and a narrow one at the extremity of the femora, 

 the genua, the base, and a broad annulus near the middle of the 

 tibige of the first and second pairs, the extremity of the femora, 

 the genua and tibise of the third pair, and the extremity of the 

 femora, the genua, and about two-thirds of the tibise from the 

 base of the fourth pair, with the metatarsi and tarsi of all the 

 legs, have a dark-brown hue ; the first pair is the longest, then 

 the second, and the third pair is the shortest ; the tarsi are ter- 

 minated by claws of the usual number and structure. The palpi 

 are short, and of a yellow colour, the digital joint, which has a 

 curved, slightly pectinated claw at its extremity, being strongly 

 tinged with brown. The abdomen is subcylindrical, projecting 

 over the base of the cephalothorax, and is broader at the anterior 

 than at the posterior extremity, which is rounded and extends 

 beyond the spinners ; it is thinly clothed with short hoary hairs 

 on the upper part and sides, and is of an olive-brown colour, the 

 under part being the darkest ; a broad, yellow, transverse band 

 near the anterior extremity passes along the upper part of each
