Ptcropus mascarinus, Mason. 



355 



Tlie above remarks may be briefly epitomized as follows : — 

 Pt. mascarimis is very closely related to, perhaps identical 

 with, Pt. roclricensis ; Mr. Mason was unaware of this fact, 

 and therefore failed to point out any character by which 

 it can be distinguished from Pt. rodricensis ; and he has not 

 given a particle of evidence that Pt. mascarinus is an extinct 

 species.
