This series when compared with European specimens is so very 

 different that it seems very doubtful whether it should be only ac- 

 corded subspecific rank. They are clear slaty gray on the back with- 

 out the brownish wash seen in P. i. infaustus; below they are lighter 

 gray with a slight buffy wash, quite different from the tawny of 

 P. i. infaustus. This series measures as follows :
