large spine, the extra-orbital angle, which all but readies 

 the level of the rostrum. 



The carapace, of an elegant urn-shaped outline, is depressed, 

 with distinct carinated lateral margins, which are only once 

 interrupted ; it is, in fact, more brachyurous ; the areolation, 

 however, differs in no essential particular from that of other 

 forms. 



The linea anomurica is very distinct, dorsal in position, 

 and runs to the interval between the supra-orbital and antennal 

 spines. The last two joints of the fifth pair of legs form an 

 imperfect subchela, the short dactylopodite not nearly reaching 

 the nevertheless well-developed toothed process of the base of 

 the propodite ; their meropodites reach the end of the extra- 

 orbital angle when laid forwards.

The basal segment of the eye-peduncle not being elon- 

 gated the eyes do not extend beyond the edges of the decurved 

 lateral parts of the anterior margin of the carapace, and there 

 are hence no orbits. The surface included between the ante- 

 rior margin of the carapace above and at the sides on the one 

 hand, and the antennary sternum on the other, is, above the 

 ocular sternum, of considerable vertical extent, and is augu- 

 lated supero-internally on each side of the rostrum for the 

 reception of the longitudinally-plicated antennules ; it is 

 apparently made up of the ocular and antennulary sterna and 

 descending laminge of the fore margin of the carapace. The 

 stout triangular and decurved rostrum extends but little 

 beyond the antennal spines, the rostral and supra-orbital 

 spines are small, sharp, recurved, and superior ; the anterior 

 margin of the carapace terminates below in a sharp antennal 

 spine. The carapace is pubescent, thick, of somewhat macru- 

 rous form, anteriorly, in front of the two spines which are 

 placed on the lateral lobes between the two divisions of the 

 cervical groove, semicircular in outline, with the upper surface 

 convexly declivous; behind these two spines it is parallel-sided, 

 with the middle part of the upper surface flat and the lateral 

 parts rounded ; it bears two spines in the position of those 

 which form the outer boundary of the orbit in Paromolopsis 

 Cuvieri, with which it agrees exactly in areolation and tolerably 

 closely in the degree to which the hepatic regions are 

 advanced ; the lateral margins are still less marked, being
