hepatic groove, this spine being larger than the three 

 others and overhanging the unarmed, rounded, antero- 

 inferior angle of the carapace. 



First to third abdominal terga rounded, the Srd without 

 any trace of carina; 4th — gth terga strongly carinate. 



Antennular flagella both compressed, of equal length, as 

 long as the carapace, abruptly acuminate at their extre- 

 mities; upper flagellum narrow, presenting along its whole 

 length the same breadth of 0.7™"", lower flagellum at its 

 proximal extremity almost twice as broad, slightly narrow- 

 ing distally, appearing therefore near the tip as narrow as 

 the upper flagellum. 



Length of carapace, rostrum included, of the very in- 

 complete, single specimen (9) that was collected, 23™™ , 

 without the rostrum 19™™-; whole length 68™™-, probably, 

 because the caudal fan is much injured.

 carina not interrupted by the cervical groove, prominent 

 and reaching to the posterior margin ; lower margin of
