Diagnosis . — Rostrum usually straight, sometimes 

 slightly arched or sinuous, and long, reaching or 

 overreaching third antennular article. Antero- 

 ventral extremity of carapace forming angle of 

 about 90°; hepatic spine located ventral to level of 

 antennal spine; branchiocardiac carina with an- 

 terior end relatively far from hepatic sulcus. Tel- 

 son with three pairs of movable spines. Petasma 

 with proximal plate of dorsomedian lobule bear- 

 ing mesial crest; proximal process of rib of dor- 

 solateral lobule subcircular; ventral costa ending 

 distally in short, relatively narrow process. 

 Thelycal plate of sternite XIV with anterior bor- 

 der transverse or slightly inclined posterolater- 

 ally, straight or somewhat sinuous and with an- 

 terolateral corners almost forming right angles; 

 median ridge broadest and most salient poste- 

 riorly, usually flasklike or gently tapering an- 

 teriorly; median plate of sternite XIII cordiform, 

 with acute apex. 



Description. — Rostrum (Figure 20) almost hori- 

 zontal, usually straight, sometimes slightly 

 arched or sinuous in adult (straight or barely ar- 

 cuate in young), falling short of or overreaching 

 distal margin of antennular peduncle, its length 

 ranging from about 0.7 to 0.8 that of carapace. 

 Rostral plus epigastric teeth 11-18 (usually 11- 

 14), second rostral tooth (occasionally third) lo- 

 cated in line with orbital margin, basal teeth close 

 together, those toward apex variously spaced, and 

 extending almost to end of rostrum but occasion- 

 ally only to base of distal 0.25. Postrostral carina 

 low, although well defined, behind epigastric 

 tooth, ending just behind dorsal extremity of cer- 

 vical sulcus; minute dorsal tubercle located near 

 posterior margin of carapace. Antennal spine rela- 

 tively small; hepatic spine slightly larger than, 

 and situated ventral to level of, antennal spine. 

 Anteroventral extremity of carapace forming 

 angle of about 90° (Figure 2 LB). Antennal carina 

 almost indistinct; cervical carina sharp, accom- 

 panying sulcus well marked; hepatic carina 

 broadly sigmoid, descending obliquely antero- 

 ventrally from below hepatic spine, then turning 

 almost anteriorly in slightly concave line to apex 

 of pterygostomian spine; branchiocardiac carina 

 well marked, with anterior extremity not nearly 

 reaching posterior end of hepatic sulcus and ex-
