 Hab. Brazil [?] {Lamarck) , Australia. 



1 have very carefully studied the typical specimens of P. 

 fulva in the Cumingian collection ; and the only characters I 

 can detect in which they differ from P. brasilianus are their 

 smaller size and the very slight angulation at the periphery. 



I place P. pigra as a variety with a note of interrogation. 

 Although of much smaller size than full-grown examples of 

 P. brasilianus, there being in the National Collection a large 

 series of the latter the gradual links between them can be 

 traced ; and, allowing for difference of habitat, it may be but a 

 dwarfed form.
