PSITTACULA INSULARIS Ridgway. 



GRAYSON'S PARROTLET. 



Similar to P. cyanopygia cyanopygia but Larger (especially the 

 bill) and darker; adult male with rump, etc., cerulean, instead of 

 turquoise, blue, and with under parts of body more bluish or glaucous 

 green, in strong contrast with yellowish green of cheeks. 



° In the original description of the subspecies Mr. Brewster says "lower parts lighter 

 and more yellowish' ' ; but with a much larger series of P. c. cyanopygia and a consider- 

 able series of P. c. pallida (the latter, however, not seen by Mr. Brewster), I find that 

 while the under parts are distinctly lighter in P. c. pallida they are by no means 

 more yellowish, being, in fact, at least in' adult males, decidedly less so than in 

 P. c. cyanopygia. 



b Five specimens. 



c Ten specimens.
