Only a carapax of this species was obtained. Its breadth was five 

 and three-fourths inches ; length, three and one-fourth inches ; giving 

 the ratio of length to breadth, 1 : 1*77. The surface is polished and 

 quite smooth, with some transverse interrupted lines or scratches, and 

 a few punctated lines or spots, as shown in the figure. There is no 

 median or stomach region apparent. The beak is scarcely at all pro- 

 minent, and is a little bifid. The orbits are large. The sides of the 

 carapax are rounded and very projecting. The margin from the eye 

 to where the curve commences to bend into the lateral lobe is eremite, 

 with twelve or fourteen broad, but low and uneven crenations. The 

 posterior margin of the carapax is regularly arcuate.
