which the last is more pointed and more clearly defined than the 

 others. The carapace and the outer lace of the wrists and bands of 

 the, chelipedes are clothed with short bristles between and around 

 the tubercles, thickly on the chelipedes, but very scantily on the 

 carapace ; these bristles are also placed rather thickly on the upper 

 borders of the carpus and propodus of the walking-legs. Other 

 finer and somewhat longer hairs are scattered over the whole 

 animal, noticeably on the upper borders of the meropodites of all 

 the legs. The inner faces of the chelipedes and lower faces of the 

 legs are quite smooth, except for a few hairs. General colour, in 

 formol, pinkish red blotched with bluish white.
