ing the first, and the third pair is the shortest ; each tarsus is 

 terminated by two curved, pectinated claws ; the palpi are short, 

 and have a curved, pectinated claw at their extremity. The co- 

 lour of these parts is pale dull-yellow, the sternum being the 

 palest ; there is a minute brown spot near the base of the falces, 

 in front, and their extremity is whitish ; two small black spots 

 occur on the under side of the femora of the first pair of legs, 

 one near the base and the other near the extremity, and there is 

 a black transverse streak, which does not form an annulus, at 

 the extremity of the genual, tibial, and metatarsal joints of each

The legs are slender, provided with hairs and long spines, 

 and are of a brownish-yellow hue; there are two minute black 

 spots on the upper surface of the tibise, three on the metatarsi 

 of the first and second pairs, and two on the metatarsi of the 

 third and fourth pairs ; the second pair is the longest, then the 

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

 nated by a si7i(/le slender, curved, pectinated claw, below which 

 there is a small scopula. The eyes are seated on black spots, 

 and are disposed on the anterior part of the cephalothorax in 

 two transverse rows; the four anterior ones, which are the 

 largest, form a straight row, situated near the frontal margin, 

 and the other four constitute the posterior row, which is rather 

 the longer and slightly curved, having its convexity directed 

 backwards. The cephalothorax is compressed before, truncated 

 in front, greatly rounded on the sides, convex in the middle, 

 sloped to each extremity, with a narrow longitudinal indentation 

 in the medial line of the posterior region, and is of a yellow- 

 brown colour, the lateral margins being much the palest. The 

 falces are powerful, conical, vertical, and armed with teeth on
