The cephalothorax is somewhat compressed before, rounded 

 on the sides, glossy, convex, particularly in the posterior region, 

 with a slight indentation in the medial line, and some short, 

 strong, black hairs on each side of its base ; it is of a yellowish- 

 red colour, a fine black line extending from each eye of the an- 

 terior pair to the frontal margin, which haa a dark brown spot 

 on each exterior angle. The falces arc powerful, subconical, 

 and vertical ; the maxilla; are long, obliquely truncated at the 

 extremity, on the outer side, and slightly inclined towards the 

 lip, which is broader towards the extremity than at the base, 

 and truncated at the apex ; the sternum is heart-shaped, and 

 thinly clothed with short, light-coloured, and long, erect, brown- 

 ish hairs; the legs are slender, and provided with hairs and 

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

 the third pair is the shortest; each tarsus is terminated by three 

 claws ; the two superior ones arc curved and pectinated, and the 

 inferior one is inflected near its base ; the palpi arc short, and 

 have a curved pectinated claw at their extremity. These parU 

 have a dull yellowish hue ; a black line extends along the infe- 

 rior surface of the femoral joint of the legs, those on the femora 

 of the posterior pair being the least conspicuous ; and a fine 

 longitudinal line of the same hue occurs on each falx in front, 

 which lines appear like a prolongation of those on the frontal 

 margin. The eyes are seated on black spots on the anterior 

 part of the cephalothorax; the four posterior ones form a 

 strongly curved transverse row, whose convexity is directed 

 backwards, each lateral eye being placed on a minute tubercle; 

 the other four describe a trapezoid whose shortest side is be- 

 fore; the posterior eyes of the trapezoid are the lai^est, and 

 the anterior ones much the smallest of the eight. The abdomen 

 is oviform, somewhat pointed at the spinners, convex above, 

 and projects a little over the base of the cephalothorax ; it is of 

 a yellowish-grey colour, finely reticulated w ith pale brown ; a 

 brown band extends along the middle of the upper part to the 

 anus, having a minute point on each side, near its anterior ex- 

 tremity, which is the darkest ; the sides are marked with oblique 

 dark brown lines, more or less confluent, which are most con- 

 spicuous on their posterior half; and a broad band of the same 

 hue, having whitish scale-like hairs on each side of it, extends 

 along the middle of the under part, and tapers to the spinners ; 

 the posterior margin of the sexual organs, which are well deve- 

 loped, is prominent, but obtuse, and their colour is brownish 

 black, that of the branchial opercula being dull yellow.
