 and vertical ; the maxillse are convex near the base, obliquely 

 truncated at the extremity on the outer side, and slightly in-

 pectinated claws. The palpi are short, and resemble the legs in 

 colour. The abdomen is very gibbous on the upper part of the 

 posterior region, and is much broader there than at the anterior 

 extremity, which has the appeai'ance of having beeu cut in a 

 direct line across ; it is of a yellowish -grey colour, with numerous

The cephalothorax is compressed before, rounded on the sides, 

 abruptly sloped at the base, depressed, with two conical tuber- 

 cles in front, placed transversely ; it is provided with numerous 

 spines enlarged at the base, those on the sides being disposed 

 for the most part in oblique rows forming slight ridges con- 

 verging towards the centre, and those in the middle constituting 

 three longitudinal rows ; three spines are situated between the 

 bases of the tubercles in front, and three others on the frontal 

 margin, the six being directed forwards ; it is of a reddish-brown 

 colour, the sides and a broad and somewhat raised band extend- 

 ing along the middle being much the darkest. The falces are 

 short, cuneiform, and vertical; the maxillae are enlarged and 

 rounded at the extremity, and inclined towards the lip, which is 

 semicircular. These parts are of a reddish-brown colour, the
