 The eyes arc disposed on the anterior part of the cephalothorax in two 

 transverse, nearly concentric, curve<l rows, whose convexity is directed 

 upwards ; the four intermediate ones describe a trapezoid, the interval 

 between the two posterior ones, which form its longest side, being 

 o-reater than the space that separates them from the lateral eyes of the 

 same row ; these organs differ little in size, the lateral eyes of the pos- 

 terior row being slightly the largest. The cephalothorax is long, 

 compressed before, rounded in front and on the sides, with furrows on 

 the latter converging towards a small indentation in the medial line ; 

 it is convex, glossy, and has a few long hairs below the eyes, and some 

 whitish ones in the i)Osterior region ; the falces are conical and some- 

 what inclined towards the sternum ; the maxillfc are convex near the 

 base, rounded at the extremity, marked with an oblique, transverse 

 furrow near the middle, and inclined towards the lip, which is short 

 and oval ; and the sternum is heart-shaped, with minute eminences 

 on the sides, opposite to the legs. These parts are of a brown-black 

 colour, the extremity of the maxillfc having a yellow-brown hue. The 

 legs are long, provided with hairs and a few spines, and have hair-hke 

 papilte on the inferior surface of the tibise, metatarsi, and tarsi; the 

 extremity of the femora, and the whole of the tibiae, metatarsi, and 

 tarsi of the first and second pairs are of a brownish-yellow colour, the 

 other parts of those limbs having a brownish-black hue ; the third and 

 fourth pairs are similar in colour, with the exception of the cox£e, 

 which have a red-brown hue, and of the tibiae of the latter, which have 

 a brownish-black colour ; the fourth pair is the longest, then the first, 

 and the third pair is the shortest ; each tarsus is terminated by two 

 small, curved claws. The palpi are long and resemble the legs in
