Carapace rhomboidal, in general outline similar to that of P. 

 lambriformis. Front emarginate ; antero-lateral borders with

 smaller tooth at the junction of the antero-lateral and postero- 

 lateral borders ; postero-lateral border with three compressed 

 conical teeth ; three prominent, sub-equal, conical teeth behind, 

 the mesial tooth situated above the other two, the latter situated 

 immediately above the insertion of the abdomen. Upper surface 

 closely granulated, a broad smooth longitudinal ridge on the 

 gastric region, followed by a row of three conical tubercles ; on 

 either side of the posterior portion of the mesial ridge, an ovoid 

 tubercular eminence, with the long axis longitudinal ; branchial 

 region with a few small tubercles. Arm, carpus, and propodos 

 closely granulated, the granules on the first coarser than those

Carapace rhomboidal, closely granulated, the posterior border 

 armed with two triangular compressed teeth ; cardiac region 

 elevated to form a prominent pyramidal eminence surrounded by 

 a narrow fissure, continuous with which anteriorly is a pair of 

 similar fissures separating the genital region from the branchials. 

 Genital region armed with a short, blunt spine ; a pair of similar 

 spines on the posterior half of the gastric region, and one on each 

 branchial region ; on each hepatic region a triangular tooth, 

 bounded behind by a narrow fissure similar to that which surrounds 

 the intestinal eminence. Front moderately prominent, bidentate. 

 Sternum and external maxillipedes covered with close-set granules, 

 which become elongated into spinules towards the anterior 

 extremities of the latter. Limbs covered all over with similar
