Technical description : Rostrum almost as long as the precervical 

 region of the carapace, extending to about midway the second pedun- 

 cular joint of the antennae, laminate, laterally compressed, armed with 

 a median dorsal crest of sharp, high, forward-curved spines, one of 

 which is the apex of the rostrum ; the series is continued posteriorly to 

 midway the cervical groove, where it bifurcates continuing posteriorly 

 as a double row ; one, occasionally two or three subdistal teeth on the 

 inferior rostral margin ; on the superior margin there is on each side 

 of the median dorsal line of spines another row of four or five sharp 

 spines directed forward and flared outward above the ocular space.
