356 Mr. J. Blackwall on newly discovered Spiders 



The legs are moderately robust, and provided with hairs and 

 sessile spines ; the first pair is the longest, then the fourth, and 

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

 curved, minutely pectinated claws, immediately below which 

 there is a small scopula ; the anterior legs are of a dark brown 

 colour, slightly tinged with red, the metatarsus being the palest, 

 and the tarsus having a reddish-yellow hue ; the colour of the 

 second, third, and fourth pairs is dull yellow, the genual joint, 

 tibia, and base of the metatarsus being tinged with red, and the 

 last joint has a small brown annulus at its extremity. The palpi 

 are short, and of a brown colour; the radial joiut has a slender 

 pointed apophysis at its extremity, on the outer side ; the digital 

 joint is of an oblong-oval form, convex and hairy externally, 

 concave within, comprising the palpal organs, which are mode- 

 rately developed, not very complicated in structure, rather pro- 

 minent at the base, and have a black, curved, filiform spine at 

 their extremity, whose point is directed towards the inner side ; 

 these organs are of a brown colour. The cephalothorax is large, 

 glossy, somewhat quadrilateral, sloping abruptly at the base and 

 projecting a little beyond the fakes in front; it is of a very 

 dark brown colour, strongly tinged with red in the region of the 

 eyes. The minute intermediate eye of each lateral row is nearly 

 equidistant from the eyes constituting its extremities. The 

 falces are short, conical, and vertical ; the maxilla? are straight, 

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

 side; the lip is short and oval; and the sternum is oval. These 

 parts are of a dark reddish-brown colour, the falces and lip being 

 the darkest, and the sternum much the palest. The abdomen is 

 oviform, pointed towards the spinners (which are prominent), 

 convex above, projecting over the base of the cephalothorax; it 

 is thinly clothed with hairs, glossy, and the colour of the upper 

 part is brown ; a pale, dull yellowish band curves round the 

 anterior extremity, and a broad slightly dentated band of the 

 same hue extends along the middle of the posterior part, and 

 terminates in a yellowish-white spot immediately above the 

 spinners ; this band is crossed by several curved, light brown 

 bars, whose convexity is directed forwards, and on each side of 

 it there are two curved yellowish lines, whose convexity is in the 

 same direction ; the sides and under part are of a dull yellow 

 colour, a broad, longitudinal, brown band occupying the middle 

 of the latter ; and the spinners, which have a dark brown hue, 

 are tipped with yellowish-white.
