Diagnosis. — Differs from P. punctata as follows: Carapace more 

 convex. Granulation coarser, plainly visible to naked eye, especially 

 prominent on the lateral margins. Subhepatic angle small, subacute, 

 tipped with a granule. Front narrower and more produced. Poste- 

 rior margin narrower, the three posterior spines slenderer. 



Color. — Grayish brown, with darker irregular spots or marmora- 

 tions, the granules white or tinged with red. (Hay.) 



Measurements. — Male (18013), length of carapace on median line 

 to tip of spine 48, to base of spine 45.3, width 42 mm. 



Range. — New Jersey to Texas, 2 to 17 fathoms.
