 comprising 19 adult males, 28 females, and 16 young males.

Carapace finely granular in the epibranchial, post-gastric and 

 cardiac regions. The two anterior tubercles are obsolescent ; the 

 other four are visible, but are not conspicuous in the adult. 



The antero-lateral borders are crennlate, two — sometimes three — of 

 the crenulations being somewhat enlarged, but never forming stout teeth. 

 The posterior and postero- lateral borders form a continuous finely-beaded 

 slightly-elevated ridge, which ends on a faintly-marked elevation, 

 situated considerably in rear of the lateral spine. The length of the

 to M. victor as re-defined by Miers and confirmed by Hilgendorf.
