each convex curve of the sinuosity including a black spot ; the 

 sides have a yellowish-white hue, their lower part being densely 

 marked with pale-brown streaks and spots; the under part is of 

 a dull-yellow colour, and comprises three longitudinal dark- 

 brown bands, which meet at the spinners. 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 describe a trapezoid, the two anterior ones, which are placed 

 on a protuberance, and are much wider apart than the posterior 

 ones, being the lai'gest of the eight; the eyes of each lateral 

 pair are seated obliquely on a minute tubercle, and are near to 

 each other, but not in contact. The cephalothorax is compressed 

 before, rounded in front and on the sides, convex, glossy, with 

 an indentation in the medial line of the posterior region ; it is of 

 a yellowish-brown colour, the cephalic region being much the 

 palest, and has a narrow brown band extending along the mid- 

 dle. The falces are conical, vertical, armed with teeth on the 

 inner surface, and have a pale brownish-yellow hue. The 

 maxillae are straight, and rounded at the extremity; and the lip 

 is semicircular, but slightly pointed at the apex. These organs 

 are of a brown colour at the base, that of their extremities being 

 pale yellow. The sternum is heart-shaped, with eminences on 

 the sides, opposite to the legs, and has a dark-brown hue tinged 

 with red. The legs are moderately long, sparingly provided 

 with hairs, and of a dull brownish-yellow colour ; the first pair 

 is the longest, then the second, and the third pair is the shortest; 

 the tarsi are terminated by claws of the usual number and 

 structure. The palpi are short, and paler than the legs. The 

 very tumid digital joint of this specimen indicates that it had to 

 undergo its final ecdysis before it arrived at maturity. 



The immature male described above was the only individual 

 of this species comprised in the collection.

The eyes are disposed on the anterior part of the cephalo- 

 thorax in two transverse rows ; the four intermediate ones, which 

 are the largest, are seated on a prominence, and nearly form a 

 square ; and the eyes of each lateral pair are placed obliquely on 

 a tubercle, and are separated by a moderately wide interval. 

 The cephalothorax is compressed before, rounded in front and 

 on the sides, convex, clothed with hoary hairs, and has an in- 

 dentation in the medial line of the posterior region ; it is of a 

 yellowish-brown colour, with a longitudinal dark-brown band in 

 the middle, which is broadest in the cephalic region, and anothe
