The i)resent species is closer to Diploexochus [Cubaris] ecliinatus 

 Brandt from Brazil than to any other described species of the genus. 

 Budde-Lund,' in his description of that form, mentions twenty spines 

 on tlic first segment of the thorax, and says there are twelve on each 

 of tlic following segments. He also describes the terminal abdomi- 

 nal segment as haA-ing the apex arcuate emarginate with the external 

 angle a little produced backward. He describes the basal article of 

 the uropoda as acute at the apex \\dth the exterior branch inserted 

 above the incision of the basal article. He also mentions only four 

 spines on each of the tliird and fourth segments of the abdomen. In 

 that species, the cpimcra of the third segment of the thorax also are 

 cleft. The epimera of the six posterior segments of the thorax are 

 furnished with a horizontal process on either side.
