BRACHTURA. RATHBUN. 101 



The major cheliped is considerably heavier than the 

 minor one; of the 25 specimens possessing chelipeds, all 

 but four have the major cheliped on the right side. On the 

 upper border of the arm distad of the middle there is a 

 rounded lobe ; dorsal aspect of wrist an elongated rhomb, 

 with a spine at the inner angle, and a smaller one at the 

 outer angle. In the male the dark brown colour of the 

 immovable finger embraces a small part of the palm except 

 in its upper part where it does not quite cover the pre- 

 hensile edge; on the dactylus the colour does not quite 

 cover the proximal end but seems to cover the prehensile 

 edges when the fingers are closed. In the female the brown 

 is much more restricted, extending on the outside edges 

 less than half the length from the tip in the full-grown, or 

 quite half the length of the dactylus in the half -grown ; on 

 the prehensile edges the colour runs much further, half or 

 more than halfway on the immovable finger, and nearly the 

 whole length on the minor dactylus and quite the whole 

 length on the major dactylus. 



Ambulatory legs long and slender; last three articles 

 sparsely fringed with long, fine hair ; the dactyli have also 

 two marginal stripes of dense pubescence. 



The male abdomen is nearly triangular from the third 

 segment to the tip, posterior margin of terminal segment 

 arcuate. The sternal furrow just in front of the bases of 

 the chelipeds forms a slightly obtuse angle at the median 

 line.
