The cephalothorax is large, glossy, somewhat quadrilateral, sloping 

 abruptly at the base, ))r()jccting a little beyond the fnlccs in front, 

 with a broad depression near the middle, and a slight, narrow 

 indentation in the medial line of the posterior region ; it is of 

 II brownish-black colour, with a band extending along each latcrnl 

 margin, and a minute spot in the broad depression, composed of 

 white hairs, and ferruginous hairs occur on the frontal margin and 

 about the anterior eyes. The minute intermediate eye of each lateral 

 row is nearly equidistant from the eyes constituting its extremities. 

 The falces are conical, vertical, and armed with teeth on the inner 

 surface ; the maxillEc are straight, and enlarged and rounded at the 

 extremity ; the lip is oval ; and the sternum is oval, and clothed 

 with whitish hairs. These ])arts are of a dark-brown colour, the 

 sternum being the darkest ; and the extremities of the maxilla; and 

 lip have a yellowish-brown hue. The legs are robust, and provided 

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

 the coxa; are of a dark-brown hue above, and pale yellow underneath; 

 the femora and genua have a dark-brown hue tinged with yellow,

 metatarsi, and tarsi is yellow-brown, with dark-brown annuli, the 

 tarsi being the palest ; the fourth pair is the longest, then the third, 

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

 curved claws, below which there is a small scopula. The pal])i are 

 sup])licd with long pale hairs, especially on the inner surface of the 

 radial and digital joints, and arc of a yellowish-white colour, with the 

 exception of the base of the humeral joint, which has a dark-brown 

 hue. The abdomen is oviform, convex above, and ])rojeets a little 

 over the base of the cephalothorax ; the upper part is of a very dark- 

 brown colour, with irregular lateral margins, and is clothed with 

 yellowish and pale reddish hairs intermixed, which form a few spots 

 on each side of its anterior half, aud angular lines, whose vertices are
