Length of the male 5 in. ; length of the cephalothorax jV> breadth xe > 

 breadth of the abdomen 2V 5 length of an anterior leg ^V ; length of 

 a leg of the third ])air \. 

 The legs are slender and very unequal in length, the first and second 

 pairs being much longer than the third and fourth pairs ; they are 

 provided with hairs, and are of a pale-yellowish colour, the extremity 

 of the femora, genua, tibiae, metatarsi, and tarsi of the first and second 

 pairs having a led-brown hue, which is much the darkest on the tibiaj 

 and metatai'si, where it forms broad annuli; the first pair a little sur- 

 passes the second in length, and the third i)air is the shortest ; each 

 tarsus is terminated by two curved, pectinated claws. The palpi are 

 short, provided with some black bristles, and are of a pale yellowish 

 colour, with a small red-brown spot on the upperside of the extremity 

 of the humeral joint, and a black one at the end of the digital joint ; 

 the radial, which is smaller than the cubital joint, projects a long, 

 straight, pointed apophysis from its outer side ; the digital joint is 

 oval, convex and hairy externally, concave within, comprising the 

 palpal organs, which are moderately developed, lenticular in form, 

 and of a pale red-brown hue, the outer margin being the darkest. 

 The cephalothorax is broad, moderately convex, glossy, slightly 

 compressed before, truncated in front, and rounded on the sides, 

 winch are marked with slight furrows converging towards the nuddle ; 

 it has a few very short black bristles distributed on the sides, a series 

 of minute, close-set black points on each lateral margin, and some 

 black bristles on each side of the frontal margin ; it is of a pale 

 brownish-yellow colour, the medial line being much the palest ; a 

 faint yellowish -bi'own band extends from each lateral eye of the 

 posterior row to its base, and a white, transverse line jjasscs between 

 the intermediate eyes of both ro\vs to the tubercles on which the 

 lateral eyes are seated. The eyes are disposed on the anterior part of 

 the cephalothorax in the form of a narrow crescent, whose convexity 

 is directed forwards ; they are black, with the exception of the inter- 

 mediate ones of the anterior row, which have a red-brown hue, and 

 are encircled with white ; the lateral eyes of both rows, which are the 

 largest, are seated on a strong tubercle, but are not in contact. The 

 falces are cuneiform and vertical ; the maxillaj are convex at the base, 

 obliquely truncated at the extremity, on the outer side, and inclined 

 towards the lip, which is triangular; and the sternum is heart-shaped. 

 These parts have a pale-yellowish hue. The abdomen is oviform, 

 glossy, somewhat depressed, sparingly supplied with very short black 

 bristles, jirojects a little over the base of the cephalothorax, and is of 

 a light yellowish red colour, the under part being the palest; on each 

 side of the upper part there is a series of six slightly depressed, light- 

 brown spots, which, with a single one in the medial line of the
