Length of the female (not including the spinners) ^ of an

The cephalothorax is somewhat quadrate, but rounded on the 

 sides ; it is convex and glossy, but slopes abruptly at the base, 

 and gradually to the front, which projects a little beyond the 

 mandibles ; it has a small indentation near the middle, and is 

 provided with a few scattered black hairs, eight, longer than the 

 rest and closely grouped, having the appearance of a slightly 

 curved horn, situated near the minute intermediate eye of each 

 lateral row on its outer side; the falces are short, subconical, 

 and vertical ; the maxillse are straight, and enlarged and rounded 

 at the extremity ; the lip and sternum are oval, the latter being 

 broader at its posterior than at its anterior extremity ; the legs 

 are robust, particularly those of the first and second pairs, and 

 are 'provided with hairs and spines, two parallel rows of the 

 latter occurring on the inferior surface of the tibiae and meta- 

 tarsi of the first and second pairs ; the third pair is the longest, 

 then the fourth, and the second pair is the shortest ; each tarsus 

 is terminated by two curved, slightly pectinated claws, below 

 which there is a small scopula ; the palpi are slender, and are 

 supplied with numerous whitish hairs, especially on the digital 

 joint. These parts are of a yellowish-brown colour, the sternum 

 and palpi being the palest. The eyes are nearly encircled by 

 short, coarse, white hairs ; the lateral eyes are seated on tuber- 

 cles placed on dark reddish-brown patches, the minute one of 

 each row being nearer to the anterior than to the posterior eye 

 of the same row. The abdomen is oviform, pointed at the spin- 

 ners (which are prominent), densely clothed with hairs, mode- 

 rately convex above, and projects over the base of the cephalo- 

 thorax; the upper part is of a brownish-yellow colour tinged 

 with red on its margins, the posterior margin forming'acur<»€ 

 above the spinners whose convexity is directed forwards ; a line 

 composed of minute black spots borders each lateral margin of 

 the upper part, and a band of the same hue, which is supplied 

 with white hairs having a silvery lustre, extends along the mid- 

 dle ; this band increases in breadth to its extremity, which is 

 crescent-shaped; the sides and under part have a pale dull- 

 yellow hue ; the former are clothed with white hairs, and have 

 a broad, irregular, brownish-black band extending along each, 

 whose continuity is interrupted at its posterior extremity; a
