The abdomen is oviform, somewhat depressed, and projects a 

 little over the base of the cephalothorax ; it is clothed with pale- 

 yellow hairs, and is of a yellowish colour faintly tinged with 

 brown, the under part being much the palest ; two brown lines 

 extend from the anterior extremity to the middle of the upper 

 part, where they meet, and are followed by a series of angular 

 lines of the same hue, which diminish in size as they approach 

 the spinners, and have their vertices directed forwards ; the sides 

 are marked with numerous longitudinal brown streaks, and the 

 under part is spotless. The eyes are disposed on the anterior 

 part of the cephalothorax in two transverse, nearly parallel rows; 

 the four constituting the anterior row, which is the shorter, are 

 rather the largest, and are situated immediately above the frontal 

 margin. The cephalothorax is large, slightly compressed be- 

 fore, truncated in front, rounded on the sides, convex, glossy, 

 thinly clothed with pale hairs, and has a narrow indentation in 

 the medial line of the posterior region; it is of a dull-yellow 

 colour, with a faint brown line extending from the intermediate 

 eyes of the posterior row to the medial indentation, and the 

 frontal margin has a dark-brown hue. The falces are powerful, 

 conical, vertical, armed with teeth on the inner surface, and are of 

 a brownish-black colour faintly tinged with red at the base. The 

 maxillae are short, straight, powerful, and rounded at the ex- 

 tremity ; the lip is broader than long, and somewhat quadrate ; 

 and the sternum is heart-shaped, and supplied with long, pale 

 hairs : these parts are of a pale-yellowish hue, the lip being 

 the darkest. The legs are robust, glossy, provided with sessile 

 spines, and have brown hair-like papillse on the inferior surface 

 of the tarsi and also on the extremity of the metatarsi of the 

 first and second pairs; the second pair is the longest, then the 

 first, and the third pair is the shortest ; each tarsus is termi- 

 nated by two curved, pectinated claws ; the palpi have several 

 long spines on their radial and digital joints, and the latter, 

 which has numerous hairs at its extremity, on the under side, is
