The carapace is narrow anteriorly, especially behind 

 the eyes, but depressed and broadly expanded posteriorly 

 at the bases of the walking legs. Gastric region 

 prominent. Cardiac region sharply prominent, tuberculi- 

 form. Hepatic region with a strong, deflexed lateral 

 tooth. Frontal region protuberant, setigerous. Rostrum 

 depressed much below the level of the frontal region, 

 broader than long, more or less expanded, naked, with a 

 slight median keel ; margin rounded. The basal joint 

 of external antennas is deeply concave on each side of the 

 keels or crests, which meet at its anterior extremity where 

 the flagellum is inserted. The fourth joint of the external 

 maxillipedes is expanded, with the antero-external angle 

 prominent and sharp. The pterygostomian regions have 

 lamelliform ridges defining the afferent branchial channels. 

 The hands have long, non-gaping fingers, finely toothed 

 along their cutting edge. The external half of the walk- 

 ing legs are hairy, with the last joint but one more or less 

 straight.
