digital joint, which has a brown hue ; the cubital joint has a 

 long bristle in front, and the radial joint is prominent on the 

 outer side; the digital joint is oval, with a brownish-black, 

 glossy process at its base curved outwards ; it is convex and 

 hairy externally, concave within, comprising the palpal organs, 

 which are highly developed, very protuberant, complex in struc- 

 ture, with two processes at their extremity, one of which is much 

 larger and more obtuse than the other, and two on the outer 

 side, the posterior one, which is somewhat convex, being much 

 the most prominent; the colour of these organs is dark and 

 light reddish-brown intermixed. The convex sides of the digital 

 joints are directed towards each other. The eyes are seated on 

 black spots on the anterior part of the cephalothorax ; the four 

 intermediate ones are placed on a prominence, and nearly form 

 a square, the two anterior ones, which are the largest of the 

 eight, being rather wider apart than the two posterior ones ; the 

 eyes of each lateral pair are seated obliquely on a tubercle, and 

 are near to each other, but not in contact. The abdomen is 

 oviform, hairy, moderately convex above, and projects over the 

 base of the cephalothorax ; the upper part is soot-coloured, with 

 some dull yellow intermixed ; it has three short yellow streaks 

 in front, and a row of depressed brownish-black spots on each 

 side of the medial line ; the sides, which are soot-coloured, are 

 palest in the medial line, and a yellow band, comprising a series 

 of somewhat triangular black spots, extends along the upper 

 part of each ; the under part has a brownish-yellow hue ; a large 

 brownish-black quadrilateral mark, surrounded by a pale yellow 

 border, occurs in the middle, and there are a few pale yellow 

 spots about the base of the spinners.

Length of the female f ths of an inch ; length of the cephalo- 

 thorax ^ ; breadth ^ ; breadth of the abdomen -^^ ; length of an 

 anterior leg \ ; length of a leg of the third pair ^. 



The legs are moderately long, slender, provided with hairs 

 and fine spines, and are of a brownish-yellow hue, with black 

 annuli ; the first pair is the longest, then the fourth, and the 

 third pair is the shortest ; the tarsi are terminated by claws of 

 the usual number and structure. The palpi, which are short, 

 resemble the legs in colour, and have a curved pectinated claw 

 at their extremity. The cephalothorax is compressed before, 

 rounded on the sides, truncated in front, sparingly clothed with 

 short grey hairs, convex, glossy, and marked with furrows on 

 the sides, which converge towards a large indentation in the 

 medial line ; the falces are powerful, conical, vertical, and armed 

 with teeth on the inner surface. These parts have a brownish-
