The eyes, which are black, are disposed on the anterior 

 part of the cephalothorax in two curved transverse rows form- 

 ing a crescent whose convexity is directed forwards ; the pos- 

 terior row is much the longer, and the intermediate eyes of the 

 anterior row are rather the largest of the eight. The cephalo- 

 thorax is short, broad, compressed before, truncated in front, 

 and has a small pointed process at each extremity of its frontal 

 margin ; it is rounded on the sides, somewhat depressed, hairy, 

 and of a yellowish-white colour ; a dark-brown band extends 

 along each side, above the lateral margin, to its base ; and 

 there is a pale-brown streak below the lateral eyes. The 

 falces arc subconical, somewhat inclined towards the sternum, 

 and have a brownish-yellow hue. The maxillae are short, 

 convex near the base, obliquely truncated at the extremity, on 

 the outer side, and strongly inclined towards the lip, which is 

 somewhat quadrate, being broader at the base than at the 

 apex ; and the sternum is heart-shaped. These parts have a 

 yellowish-white hue ; the base of the maxillfe and of the lip
