equidistant from the eyes constituting its extremities. The 

 cephalothorax is large, glossy, somewhat quadrilateral, elevated 

 in the cephalic region, and abruptly sloped at the base ; it is of 

 a dull yellow colour, faintly tinged with red, the region of the 

 eyes having a reddish-brown hue. The falces are small, conical, 

 and vertical ; the maxilla? are straight, and enlarged and rounded 

 at the exti'emity ; the lip is somewhat oval, but truncated and 

 slightly hollowed at the apex. These organs have a red-brown 

 hue, the extremity of the maxillse being the palest. The legs 

 are robust, provided with hairs and sessile spines, two parallel 

 rows of the latter occurring on the inferior surface of the tibiae 

 and metatarsi of the first and second pairs ; the third pair is the 

 longest, then the first, and the second pair is the shortest ; each 

 tarsus is terminated by two curved minutely pectinated claws, 

 immediately below which a small scopula is situated ; the palpi are 

 short, and without a claw at their extremity ; the sternum is oval 

 and glossy. These parts have a dull yellow hue, slightly tinged with 

 red. The abdomen is oviform, somewhat depressed and pointed 

 towards the spinners (which are prominent), convex at the ante- 

 rior extremity, and projects a little over the base of the cephalo- 

 thorax ; it is sparingly clothed with hairs, and is of a yellowish- 

 white colour, with an obscure, slightly curved, brownish-black 

 band, having its convexity directed forwards, situated near the 

 anterior extremity of the upper part ; on each side of the medial 

 line of the posterior half there is a series of brownish-black con- 

 fluent spots extending to the spinners, the superior pair of which 

 organs has a dark-brown and the inferior pair a red- brown hue; 

 on the under part there are two longitudinal, faint, brownish- 

 black bands which meet near the spinners; and the colour of the 

 sexual organs is dark red-brown.

The cephalothorax is large, glossy, somewhat quadrilateral, 

 very elevated in the cephalic region, and sloped abruptly at the 

 base ; it is of a dull yellow colour, tinged with red ; the region 

 of the eyes has a reddish-brown hue, and that of the frontal 

 margin, which is broad and nearly vertical, is blackish-brown. 

 The falces are long, prominent, subcylindrical, depressed and 

 indented at the extremity (which has a pointed process on the 

 outer and another on the inner side, near the articulation of the 

 fang), and are of a red-brown colour. The maxillse are straight, 

 and enlarged at the extremity, which is produced on the outer 

 side; and the lip is oval. These parts have a brownish-yellow
