are moderately developed, is dark-brown ; all the brownish-black 

 marks are more or less streaked and spotted with yellowish-white. 

 The cephalothorax is oval, convex, glossy, with slight furrows on the 

 sides converging towards an indentation in the medial line ; it is of a 

 brownish-yellow colour, with narrow, soot-coloured, lateral margins. 

 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 nearly form a square, the two anterior ones, which are placed on 

 a slight protuberance, at a moderate elevation above the frontal mar- 

 gin, being the smallest and darkest of the eight ; the eyes of each 

 lateral pair are seated obliquely on a small tubercle, and are near to 

 each other, but not in contact. The falces are conical, vertical, and 

 armed with a few teeth at the extremity, on the inner surface ; the 

 maxilla3 are convex near the base, obliquely truncated at the extremity, 

 on the outer side, and inclined towards the lij), which is semicircular; 

 and the sternum is convex, glossy, and heart-shaped. These parts 

 have a red-brown hue, the sternum and base of the lip being much 

 the darkest. The legs are moderately long, provided with hairs, 

 ami of a yellowish-brown hue, with an obscure, brownish annulus on 

 the femora and tibia; ; the first jiair is the longest, then the fourth, 

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

 claws; the two superior ones are curved and j)ectinated, and the 

 inferior one is minute and inlleetcd near its base. The i)alpi resemble 

 the legs in colour, but are without annuli, and have a curved, pecti- 

 nated claw at their extremity.

The cephalothorax is glossy, very convex in the cei)halic region, ])ar- 

 ticularly behind the eyes, whence it slopes regularly to the base ; it 

 has a shallow, oblong indentation in the medial line, and is of a dark- 

 brown colour, the base being the palest. The falces are very short, 

 conical, and vertical ; and the maxilla; are convex near the base, and 

 inclined towards the lip. These organs have a yellowish-brown hue, 

 the falces being rather the paler. The lip is semicircular, but some- 

 what pointed at the apex ; and the sternum is heart-shaped, convex, 

 and glossy. These parts are of a dark -brown colour. The eyes aie 

 dis))i)sed in two transverse rows on the anterior part of the ceplialo- 

 thorax, very high above the frontal margin ; the four intermediate 

 ones nearly form a scpiarc, the two anterior ones, which arc seated on 

 a protuberance, being the largest and darkest of the eight ; the eyes 

 of each lateral pair are placed obliquely on a minute tubercle, and ai'e 

 contiguous, the anterior one being the smaller. The legs are mode- 

 rately long, provided with hairs and some fine spines, particularly on
