The rostrum is a regular prolongation of the carapace, not 

 a post-frontal spine, as in Pasiphae ; it is acute, unarmed above 

 and below, and reaches to about one-half the length of the 

 eyestalks. The carapace is about half the length of the 

 abdomen and telson combined and is dorsally arched behind 

 the rostrum. ; posteriorly it is deep, anteriorly rather narrowed, 

 but not to such an extent as is found in the previous genus. 

 Dorsally it is carinate throughout its length, the anterior third 

 of the carina being depressed and dorsally sulcate ; this is 

 evidently a notable feature in large specimens (cf. Smith, 

 PI. V, fig. 4), but is not so conspicuous in the smaller ex- 

 amples found off the Irish coast. The anterior margin of the 

 carapace is almost straight below the orbital notch and is 

 provided with a minute point between the insertions of the 

 antennae and antennules ; the antero-lateral sulcus is rounded, 

 and rather obtuse. Laterally a well-marked sinuous carina 

 runs across the carapace near its inferior margin , disappearing 

 shortly before it reaches the posterior edge, while anteriorly it 

 terminates behind the base of the antennal peduncle.
