Description. -Rostrum (Figure 13) short, its 

 length about 0.2 that of carapace, falling short of 

 distal margin of first antennular article, horizon- 

 tal or slightly upturned, tapering to very sharp 

 tip, and with ventral margin slightly sinuous. 



Rostral plus epigastric teeth 7-9, sharp; epigastric 

 tooth situated at about 0.4 cl from orbital margin, 

 first rostral tooth (largest of all) at approximately 

 0.3, and third opposite to, or slightly forward of, 

 orbital margin. Adrostral carina low and sharp, 

 extending from orbital margin almost to apex of 

 rostrum; orbital margin projecting antero- 

 ventrally in narrow shelf. Postrostral carina well 

 defined to near posterior margin of carapace, 

 followed by small tubercle. Pterygostomian spine 

 small; postorbital (situated directly posterior to 

 relatively small antennal spine), branchiostegal, 

 and pterygostomian spines continuous with sharp 

 basal carina. Cervical carina sharp, notched dor- 

 sal to hepatic spine; cervical sulcus deep, extend- 

 ing to, but not crossing postrostral carina, its 

 dorsal extremity located at or slightly posterior 

 to midlength of carapace; hepatic carina blunt, 

 its accompanying sulcus deep; additional short 

 carina lying dorsal and parallel to posterior part 

 of hepatic sulcus; posthepatic carina long, run- 

 ning almost to posterior margin of carapace; 

 branchiocardiac carina also long, virtually reach- 

 ing posterior margin of carapace; short sulcus ex- 

 tending posterodorsally from near posterior end 

 of branchiocardiac carina; submarginal carina 

 well defined, extending along entire length of 

 branchiostegite. 



Eye (Figure 4A) with basal article produced 

 mesially into barely distinct scale; ocular pedun- 

 cle long; cornea comparatively narrow, its great- 

 est diameter about 1.4 times that of base of ocular 

 peduncle, its proximal margin only slightly slant- 

 ing posterolateral^. 



Antennular peduncle length equivalent to 

 about 0.55 that of carapace; prosartema short, ex- 

 tending only as far as distomesial margin of 

 cornea, falling considerably short of distal margin 

 of first antennular article; stylocerite short, ex- 

 tending only 0.4-0.5 of distance between its prox-
