depressed and truncated in front, sparingly clotlied with short 

 hairs, convex, glossy, and has a slight longitudinal indentation 

 in the medial line; the falces are long, powerful, subconical, 

 vertical, and armed with a fev/ small teeth on the inner surface ; 

 the maxillae are straight, and enlarged and rounded at the ex- 

 tremity ; the lip, which is longer than broad, is truncated and 

 somewhat hollowed at the apex ; and the sternum is heart- 

 shaped, with small prominences on the sides, opposite to the 

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

 first pair is the longest, then the fourth, and the third pair is 

 the shortest ; each tarsus is terminated by two curved pectinated 

 claws, below which there is a small scopula ; the palpi are mo- 

 derately long; the abdomen is oviform, somewhat pointed at 

 the spinners, convex above, and clothed with short hairs. This 

 spider is of a pale dull yellow colour, with the exception of the 

 falces, the maxillae, the lip, the sexual organs, and the extremity 

 of the palpi, which have a red-brown hue, the circular sexual 

 organs and the extremity of the falces being the darkest. The 

 eyes are disposed in two transverse rows on the anterior part of 

 the cephalothorax ; the four intermediate ones nearly form a 

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

 and are situated immediately above the frontal margin, being 

 somewhat nearer to each other than the posterior ones ; the eyes 

 of each lateral pair are seated obliquely on a tubercle, but are 

 not in contact.

The eyes are seated on black spots, and are disposed in two 

 transverse rows on the anterior part of the cephalothorax ; the 

 four intermediate ones form a trapezoid whose anterior side is 

 the shortest, the two eyes constituting it, which are situated 

 immediately above the frontal margin, being the smallest of the 

 eight. The cephalothorax is compressed before, rounded on the 

 sides, depressed and broadly truncated in front, sparingly clothed 

 with short hairs, convex, glossy, and has a narrow longitudinal 

 indentation in the medial line ; the legs are long, slender, and 

 provided with hairs and fine sessile spines ; the first pair is the 

 longest, the second and fourth pairs are equal in length, and the 

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

 curved pectinated claws, below which there is a small scopula ; 

 the sternum is heart-shaped, and has small prominences on the 

 sides, opposite to the legs. These parts are of a pale dull yellow 

 colour, the cephalothorax, which has a very obscure longitudinal 

 brownish band on each side, being rather the darkest ; and the
