The author cannot doubt the identity of the red variety of 

 this species, with the figure quoted by Gmelin. The dark 

 variet)-, which is variegated black and white, is new to our 

 collectors, Mr. Cuming having brought a number of speci- 

 mens from the Philippine Islands. The ribs are angular, and 

 much thicker than in P. varius, and the interstices are nar- 

 rower than the ribs.
