Boone, Crustacea, Cruise of "Alva," 1931 67 



The second, third and fourth pairs of legs are slender, decreasing 

 in length in the order named; the carpus has near the distal end of 

 its posterior lateral margin a small spine, on each the second and third 

 legs but not on the fourth pair. The propodus has one longitudinal 

 groove and the dactyl two grooves, on each lateral face; the inferior 

 margins of both these articles are setose; the dactyli are long, very 

 tapered, acuminate. 



The natatory legs are very stout and a subdistal spine on the an- 

 terior lateral margin of the meral joint; the propodus and dactyl are 

 laminate, subovate.
