a leg of the second pair -^\ length of a leg of the third 

 pair \. 



The eyes are disposed on the anterior part of the cephalo- 

 thorax in two transverse, curved rows, forming a crescent 

 whose convexity is directed forwards ; the four intermediate 

 ones describe a square ; and the eyes of each lateral pair are 

 seated obliquely on a whitish tubercle, the anterior one being 

 the largest of the eight. The cephalothorax is compressed 

 before, truncated in front, rounded on the sides, depressed at 

 the base, convex, with a few bristles on the anterior part, and 

 a row directed forwards from the frontal margin, which pro- 

 jects a small oval process between the bases of the falces ; the 

 sides are of a dark-brown colour passing into black at their 

 posterior part, which is glossy ; and a broad, obscure, reddish- 

 brown band extends from the eyes to the bifid extremity of a 

 short band at the base, which, with the lateral margins, is 

 white. The falces are short, strong, cuneiform, vertical, red- 

 brown at the base, with a few bristles towards the inner side, 

 white near the middle and black at the extremity. The 

 maxillge are convex near the base, pointed at the extremity, 

 and inclined towards the lip, which is triangular. The colour 

 of these parts is dark-brown at the base, and pale reddish- 

 brown at the extremity. The sternum is heart-shaped, and 

 has a fcAV bristles on each side of its anterior part ; it is of a 

 dark-brown hue obscurely freckled with yellowish-grey, the 

 lateral margins being the darkest. The legs are provided with 

 hairs and spines, two parallel rows of the latter occurring on 

 the inferior surface of the tibiae and metatarsi of the first and 

 second pairs, which are much longer and more robust than the 

 third and fourth pairs ; the second pair slightly surpasses the 

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

 nated by two curved, pectinated claws ; the predominant colour 

 of the first and second pairs of these limbs is dark-brown, the 

 anterior side and the inferior surface of the femora having a 

 greyish hue, and the extremity of the joints a yellowish-white 

 or reddish-white tint; the third and fourth pairs are of a 

 yellowish- white colour, and are marked with dark-brown spots 

 and annuli ; all the tarsi have a reddish-brown hue. The 

 palpi are short, and have a curved, pectinated claw at their 

 extremity ; they are of a yellowish-white colour, tinged with 

 red and spotted with brown, the digital joint having a reddish- 

 brown hue. The abdomen is somewhat oviform, moderately 

 convex above, broader at the posterior than at the anterior 

 extremity, corrugated on the sides and sparingly clothed with 

 short dark-coloured hairs ; the upper part, which is of a dark 

 dull-red colour, has five circular depressions on its anterior
