The abdominal segments are dorsally smooth, devoid of trans- 

 verse grooves or carinae, except on the first segment, which has 

 the normal division for articulation with the carapace. The epi- 

 meral margins of the first, second, third and fourth segments are 

 very acuminate. The epimera of the first segment is acute, blunted 

 distally and has a short, interrupted, transverse carina above 

 the "button" ; the epimera of the second segment are wider, very 

 acute distally, with a deep groove just inside the anterior lateral 

 margin, the postlateral margin convex and quadri-dentate on the 

 proximal half, the distal half is smooth, tapered; the epimera 

 of the third and fourth segments are similar to those of the sec- 

 ond segment but with the anterior lateral groove successively 

 shorter, the apex more definitely curved backward. This curva- 

 ture increases in the epimera of the fifth segment and the groove 

 is greatly reduced in the epimera of the sixth segment. 



The five pairs of legs are similar, monodactyl, subcylindrical, 

 laterally compressed, longitudinally striped in alternating cream 

 and color markings ; the merus has an acute small tooth at each the 

 lower and upper subdistal margins ; the dactyl is procurved with 

 a strong horny tip, the inferolateral border, and also that of the 

 distal propodal area are beset with numerous tufts of soft, short 

 setae.
