first, and the third pair is the shortest ; each tarsus is termi- 

 nated by three claws ,• the two superior ones are curved and 

 pectinated, and the small inferior one is inflected near its base. 

 The palpi resemble the legs in colour ; the radial is stronger 

 than the cubital joint, and the digital joint, which is of an ob- 

 long-oval form pointed at the extremity, and of a dark-brown 

 hue, is convex and hairy externally, concave within, com- 

 prising the palpal organs, which are highly developed, promi- 

 nent, complex in structure, and of a dark and a light red-brown 

 colours intermixed. The abdomen is oviform, clothed with 

 adpressed hairs, convex above, and projects over the base of 

 the cephalothorax ; it is of a very dark -brown hue, and is 

 encompassed by a broad band of white hairs ; a similar band, 

 extending along the middle of the upper part, comprises a 

 dark -brown fusiform mark ; two oval white spots, placed 

 transversely, occur on the under part, immediately below the 

 branchial opercula.

The minute intermediate eye of each lateral row is nearly 

 equidistant from the eyes constituting its extremities. The 

 cephalothorax is long and somewhat quadrilateral, with a 

 shallow depression behind the posterior pair of eyes ; it slopes 

 abruptly downwards at the base, projects a little beyond the 

 falces in front, is clothed with short yellowish hairs, and is of 

 a dark -brown colour. The falces are small, subconical, and 

 armed with a few teeth on the inner surface ; the maxillas are 

 enlarged and somewhat divergent at the extremity ; and the 

 lip and sternum are oval. These parts are of a dark -brown 

 colour, the extremity of the maxillae and the apex of the lip
