The eyes are seated on black spots, and are disposed on the anterior part 

 of the cephalothorax in two transverse rows ; the four intermediate 

 ones nearly form a square, the two anterior ones being placed on a 

 slight protuberance ; those of each lateral pair, which are seated 

 obliquely on a minute tubercle, are near to each other but not in con- 

 tact, and the anterior ones are the smallest of the eight. The cephalo- 

 thorax is convex, glossy, compi-essed before, rounded in front and on 

 the sides, with an indentation in the median line ; it is of a dull yel- 

 lowish-white hue, with a longitudinal, soot-coloured band on each 

 side, whose superior margin is dentated, and with lateral margins and 

 a short streak in the median indentation of the same hue. The fakes 

 are powerful, conical, vertical, and armed with teeth on the inner sur- 

 face ; the maxilla; are short, straight, and enlarged and rounded at 

 the extremity ; and the lip is semicircular, but somewhat pointed at 

 the apex. These parts are of a dull yellowish- white colour. The 

 sternum is heart-shaped, with eminences on the sides, opposite to the 

 legs ; it is of a dark -brown hue, with a white streak extending along 

 the middle. The legs are long, slender, provided with hairs and 

 some fine ' spines, and are of a dull brownish-yellow hue, with soot- 

 coloured spots and annuli; the first pair is the longest, then the 

 second, and the third pair is the shortest ; each tarsus is terminated 

 by claws of the usual number and structure. The palpi are short, 

 rather paler than the legs, and have a curved, slightly pectinated claw 

 at their extremity. The abdomen is glossy, of an oblong oviform 

 figure, rather convex above, and projects over the base of the cephalo- 

 thorax ; it is somewhat pointed at its extremity, which projects greatly 

 beyond the spinners, and is of a dull-white hue, reticulated with 

 numerous pale soot-coloured lines, the sides and under part being the 

 darkest ; a pale soot-coloured, ramified band extends along the mid- 

 dle of the upper part more than half of its length, and on each side 

 of it there is a series of short, oblique, black streaks ; the superior 

 margin of the sides is obscurely dentated, and a white band extends 

 on each side of the under part to the spinners.
