sliortest side is before ; the posterior eyes of the trapezoid are 

 the largest, and the anterior ones are much the smallest of the 

 eight. The cephalothorax is slightly compressed before, trun- 

 cated in front, rounded on the sides, convex, glossy, with a slight 

 indentation in the medial line ; it is of a brown colour tinged 

 with red, and has an irregular dark- brown band on each side, 

 and a spot of the same hue behind the medial indentation ; the 

 space comprised between the posterior eyes of the trapezoid and 

 those of the transverse curved row, and a spot on each exterior 

 angle of the frontal margin, are of a dark-brown colour; the 

 lateral margins and the front are provided with yellowish-white 

 hairs, and some of a pale-red hue occur on the abruptly sloped 

 base. The falces are powerful, subconical, vertical, supplied 

 with dull-yellowish hairs in front, and armed with one or two 

 minute teeth on the inner surface; the maxillse 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 clothed with short yellowish- 

 white hairs intermixed with long ones of a darker hue. These 

 parts are of a brown colour tinged with red. The legs are 

 slender, provided with hairs and long spines, and are of a paler 

 brown hue, with a few annuli of a deeper shade ; the first pair 

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

 each tarsus is terminated by three claws ; the two superior ones 

 are curved and pectinated, and the inferior one is inflected near 

 its base. The palpi, which are without annuli, resemble the 

 legs in colour, and have a curved, pectinated claw at their 

 extremity. 



A single specimen of this species was included in the collec-
