PSITTACIDAE, 



t x\mazona leucocephala caymanensis (Cory). 



Ten specimens, both sexes, all adult, Grand Cayman, May and 

 June. 



This well-marked form is peculiar to Grand Cayman. I agree with 

 Todd (Annals Carnegie mus., 1911, 7, p. 418) that its relationship to 

 true leucocephala of Cuba, which is close, is best expressed by the use 

 of trinomials. 



Brown noted that the skin of the orbital region, ^•aried from white 

 to flesh-color. He took a set of four eggs together with the female 

 parent on May 12. 



Amazona leucocephala hesterna, subsp. nov.
