This is a distinct species, and is very readily identified. The cephalic segment is small, 

 cordate, quadrate ; dental plates very distinct, and deeply excavated on their surface ; 

 teeth six, the internal one bifid ; dorsal segments with free elevated lateral margins. 

 The posterior pair of legs are short, very broad, depressed, quadrate, with the external 

 and internal margins rounded ; the internal margin and surface of the femoral joint 

 with eight or nine minute, irregularly-distributed, black spinulse, the angular one qua- 

 drifid. Inferior surface flattened, with nine spinulae arranged in three longitudinal 

 series. Lateral anal appendages very short ; preanal scale quadrate cordate, with the 

 posterior margin slightly rounded.

 saturate ferrugineis, dentibus labialibus 6 : intimis acutis latis spathulatis : extimis an- 

 gustatis acutissimis, pedum postremorum articulo basali elongate subconvexo interne 

 inferneque spinulis numerosis minutis nigris inferioribus transversim seriatis armato.

Cephalic segment cordate, rounded posteriorly; basilar segment very large; mandibles 

 strong, with the tooth small, but armed with a minute tubercle near its apex ; labium 

 flattened, with the transverse suture distinct ; dental plates quadrate, with the poste- 

 rior margin slightly elongated; teeth six, large, with the internal one on each side 

 sharp, broad, spatulate and formed for cutting, with the two external ones on each side 

 narrowed and very acute ; femoral joint of the posterior pair of legs elongated and flat-
