extent as they approach the spinners ; their vertices are di- 

 rected forwards, and their extremities are enlarged ; the sides 

 are marked with oblique streaks of the same hue, the anterior 

 one being the broadest ; and there are a few small soot-coloured 

 spots on the under part ; the spinners are long, especially those 

 of the superior pair, which are triarticulate, with the spinning- 

 tubes situated on the extremity of the short terminal joint ; 

 these organs are cylindrical, very prominent, and of a yellowish- 

 brown hue tinged with red, the inferior pair being the strongest 

 and much the darkest-coloured. The eyes are disposed on the 

 anterior part of the cephalothorax in two transverse rows ; the 

 two intermediate ones of the posterior row, which is almost 

 straight, are nearer to each other than they are to the lateral 

 eyes of the same row, which are the smallest ; the anterior 

 row is the shorter, and is curved, having its convexity directed 

 upwards ; the two intermediate eyes are the largest and 

 darkest-coloured of the eight, and the lateral eyes of the two 

 rows are separated by a wide interval. The cephalothorax is 

 large, convex, depressed towards each extremity, glossy, thinly 

 clothed with hairs, compressed before, and rounded on the 

 sides, which are marked with slight furrows converging to- 

 wards a narrow indentation in the medial line of the posterior 

 region ; it is of a reddish-brown colour, with narrow dark- 

 brown lateral margins. The falces are powerful, conical, 

 nearly vertical, and have a red-brown hue. The maxillae are 

 convex at the base, rounded at the extremity, near which there 

 is an oblique transverse furrow, and are strongly curved to- 

 wards the lip, which is long and rounded at the apex ; and 

 the sternum is oval. These parts have a yellowish-brown hue, 

 the lip, which is the darkest, having a tinge of red. The legs 

 are moderately robust, provided with hairs and sessile spines, 

 and have a yellowish-brown hue ; the fourth pair is the longest, 

 then the first, and the third pair slightly surpasses the second ; 

 each tarsus is terminated by two curved, pectinated claws, and 

 has hair-like papillae on its inferior surface. The palpi re- 

 semble the legs in colour ; and the radial, which is rather 

 shorter than the cubital joint, projects a small obtuse protube- 

 rance from its extremity, on the underside, and a red-brown 

 pointed apophysis in front, towards the outer side ; the digital 

 joint is oval, convex and hairy externally, concave within, 

 comprising the palpal organs, which are well developed, with 

 a long curved spine on the inner side, whose pointed extremity 

 extends beyond the concavity, and a crescent-shaped process 

 towards the outer side, whose longer limb is recurved at its 

 extremity; their colour is dark reddish-brown mixed with 

 yellowish-brown.
