situated immediately above the frontal margin, are the largest of 

 the eight, and the posterior row, which is the longer, is slightly 

 curved, with its convexity directed backwai'ds. The cephalo- 

 thorax is large, somewhat compressed before, greatly rounded 

 on the sides, sparingly clothed with hairs, convex, glossy, and 

 has a very slight longitudinal indentation in the medial line ; 

 the falces are short, subcorneal, vertical, and armed with a few 

 teeth on the inner surface; the maxillae are straight, convex 

 near the base, and rounded at the extremity ; the lip is quadrate; 

 and the sternum is heart-shaped; the legs are robust, and pro- 

 vided with hairs and sessile spines, a row of the latter occurring 

 on each side of the under part of the tibiae and metatarsi ; the 

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

 the shortest ; each tarsus is terminated by two curved minutely 

 pectinated claws, below which a small scopula is situated. These 

 parts are of a brownish-yellow colour, with the exception of the 

 sternum, which has a yellowish-white hue. The palpi resemble 

 the legs in colour, but the digital joint has a dull brown spot 

 near its extremity, and several streaks of the same hue on its 

 convex surface ; the cubital and radial joints are short, and the 

 latter projects from its extremity in front a red- brown crescent- 

 shaped apophysis, whose outer limb is the shorter; the digital 

 joint is of a curved oblong-oval figure, and is deeply emarginated 

 towards the extremity on the outer side ; it is convex and hairy 

 externally, concave within, comprising the palpal organs ; these 

 organs are highly developed and complicated in structure, with 

 a large prominent spiral process, which extends beyond the 

 extremity of the joint, and has a long slender filament in con- 

 nexion with it, and a prominent spine near its base towards the 

 outer side ; their colour is red-brown, tinged with yellow. The 

 abdomen is oviform, convex above, pointed at the spinners, and 

 clothed with short hairs ; it is of a dull yellowish hue, with a 

 series of reddish-brown angular lines, whose vertices are directed 

 forwards, extending along the middle of the upper part, and 

 diminishing in extent as they approach the spinners ; from the 

 extremities of the angular lines spots of the same colour extend 

 in oblique rows to the sides, and a few obscure spots of a similar 

 hue occur on the under part.
