lip. These organs have a brownish-yellow hue, the latter being 

 much the darker-coloured. The lip is short, broad, slightly 

 dilated in the middle, and somewhat pointed at the apex; and 

 the sternum is heart-shaped, with a slight inward curve at the 

 extremity, which has a small protuberance at its centre; and 

 there are minute prominences on the sides, opposite to the legs. 

 These parts are of a dark-brown colour, the apex of the former 

 and the lateral margins of the latter having a yellowish-white 

 huCi The palpi are short, and of a yellowish-white colour, the 

 digital joint, which tapers to a point, and is well supplied with 

 hairs, having a brown hue. The abdomen is short, somewhat 

 convex above, sparingly clothed with pale hairs, projects slightly 

 over the base of the cephalothorax, and has at its extremity a 

 conical protuberance situated high above the spinners; it is of 

 a yellowish-grey colour, with a red-brown spot on each side of 

 its anterior extremity, a few oblique black streaks on each side 

 of the medial line of the upper part, and a curved line and spot 

 of the same hue on the conical protuberance; in the space 

 between the protuberance and the spinners there is a vertical 

 black line, on each side of which an obscure, curved, whitish 

 line occurs ; a broad, longitudinal brownish-black band, mingled 

 with yellowish-grey, occupies the middle of the under part ; the 

 anterior part of the band is the broadest, and comprises two 

 contiguous, oval, divergent, dull-yellow spots : the sexual organs 

 are highly developed, rather prominent, and present a narrow, 

 transverse orifice ; they are of a red-brown hue, and the anterior 

 margin, which is the darker-coloured, particularly at its extremi- 

 ties, has a small prominence in the middle. 



The sexes are similar in colour ; but the male is the smaller, 

 and the femur of each anterior leg is provided with a longitu- 

 dinal row of erect black spines on its inferior surface, which 

 extends from its extremity nearly to its base. The falces are 

 somewhat hollowed on the inner surface, and have a conical, 

 pointed process on the outer side, towards their extremity, near 

 the base of which, on the inner side, a tooth-like process origi- 

 nates, that is directed obliquely inwards and downwards. The 

 palpi are short, very robust, and of a pale-yellow colour, with 

 the exception of the digital joint, which has a dark reddish- 

 brown hue on its sides and extremity; the humeral joint is 

 slender at its base, but its extremity is enlarged and convex 

 underneath; the radial joint is greatly dilated, very convex 

 above, and much larger than the cubital joint; the digital joint 

 is supplied with some long hairs, and tapers from the base 

 to the extremity, which is terminated by a fine, curved, pointed 

 process ; the palpal organs are connected with the base of the 

 digital joint, towards the inner side ; they are subglobose, of a
