The carapace is narrow especially posteriorly, cordiform, smooth, 

 extremely convex in every direction, finely granulated and punctate, 

 unbroken by interregional furrows, the posterior boundary of the 

 gastric area alone being faintly indicated ; epigastric lobes hardly 

 perceptible in some specimens ; post-frontal ridge feebly developed, 

 interrupted, most apparent behind the eyes ; postero-lateral mar- 

 gins rounded off, marked with extremely delicate oblique wrinkles 

 which pass downwards and forwards on to the branchial floor 

 which is much swollen ; antero-lateral margins rounded, inclined, 

 bearing rudimentary epibranchial teeth which pass backwards 

 and inwards for a short distance as an obscure, crenulated crest. 

 Front broad, deflexed, terminated by a nearly straight free margin ; 

 its anterior third flattened and perfectly vertical. Orbits oval with 

 ol >sc nrely crenated margins, not at all salient ; their external angles 

 scarcely projecting beyond the general level of the orbital margins ; 

 anterior pleural regions convex, finely granulated, separated near 

 their internal boundaries from the rest of the inferior surface of the 

 carapace by a well defined, finely tuberculated line, passing directly
