hairs intermixed^ and a dark brown spot occurs on each exterior 

 angle of the frontal margin. The falces are long, powerful, 

 subconical, inclining to cuneiform, and vertical; the maxillae 

 are enlarged where the palpi are inserted, truncated at the ex- 

 tremity on the outer side, and inclined towards the lip, beyond 

 which they extend considerably ; the lip is long, somewhat tri- 

 angular, and notched at the apex ; the sternum is heart-shaped ; 

 the legs are long, slender, and provided with hairs and long 

 spines ; the first pair is the longest, then the second, and the 

 third pair is the shortest; the tarsi are terminated by three 

 claws; the two superior ones are curved and pectinated, and 

 the inferior one is inflected near its base ; and the palpi, which 

 are short, have a curved pectinated claw at their extremity. 

 These parts are of a pale red-brown colour; the falces are the 

 darkest, and the femur of each leg has two longitudinal brown 

 lines on its inferior surface. The abdomen is long, slender, 

 somewhat cylindrical, tapering to the spinners, and projects 

 slightly over the base of the cephalothorax ; it is densely clothed 

 with short hairs, and the upper part, which is of a yellow-brown 

 colour, bordered laterally by a red -brown line, is marked with 

 numerous pale yellow streaks and spots symmetrically arranged, 

 and disposed on similar streaks and spots either of a dark brown 

 or of a red-brown hue; the colour of the under part is yellowish 

 white ; a large black band extends along the middle, whose an- 

 terior part comprises a short, longitudinal, yellowish-white 

 streak ; the sexual organs are highly developed, nearly circular, 

 and of a dark reddish-brown colour, that of the branchial oper- 

 cula being yellowish brown.

The cephalothorax is somewhat quadrate, the sides being 

 slightly rounded; the anterior part is thinly clothed with short 

 hairs, abruptly elevated throughout its entire breadth, and has 

 on its summit two glossy protuberances which are separated by 

 a longitudinal furrow; and the posterior part is depressed, with 

 a large indentation in the medial line ; it is of a dark brown 

 colour faintly tinged with red, the middle of the posterior part 

 having a yellow-brown hue. The eyes are small, and situated 

 immediately above the frontal margin ; the four intermediate
