serratus" [= P. challengeri] lacks an epipod on so- 

 mite XII (third pereopod), whereas P. rectacuta 

 has one. This observation is in error; not only both 

 of these species possess such an epipod, but also its 

 presence is typical of all members of the genus.

Diagnosis. — Rostrum straight or sinuous, and 

 long, reaching or overreaching third antennular 

 article. Anteroventral angle of carapace broadly 

 obtuse. Telson with two pairs of movable spines. 

 Petasma with proximal plate of dorsomedian 

 lobule lacking mesial crest; proximal process of 

 rib of dorsolateral lobule subcircular; ventral 

 costa lacking distolateral projection and ending 

 distally in long spine extending beyond level of 

 row of cincinnuli. Thelycal plate of sternite XIV 

 with anterior border weakly to distinctly arched 

 on each side of posteromedian projection of ster- 

 nite XIII and strongly sloping posterolaterally; 

 lateral borders turning mesially behind mid- 

 length, then posteriorly; short posteromedian 

 protuberance caudally pedunculate. 



Description. — Rostrum (Figure 11) horizontal or 

 somewhat upturned, straight or slightly sinuous 

 (strongly arched in young), and long, reaching at 

 least midlength of third antennular article and 

 often overreaching peduncle, its length ranging 

 from about 0.7 to 0.9 that of carapace. Rostral
