The carapace is oval, and finely granular on the 

 sides. The front, advanced much beyond the orbital 

 angles, is round and scarcely depressed in the middle 

 line ; its edge has fine teeth. The postorbital angle is 

 spiniform ; there is a small spine within and in front 

 of the branchial region. The gastric region has three 

 projections, one middle, the others lateral ; cardiac region 

 is prominent. The internal ant^miffi are long and thin,
