OCT., 1909. BIRDS OF THE LEEWARD ISLANDS CORY. 211 



Family Psittacidae. 



Amazona ochroptera rothschildi (Hartert). 



Chrysotis rothschildi Hartert, Bull. Brit. Orn. Club, No. Ill, 1892, 

 p. xii. Id. Ibis, 1893, p. 123. Id. Ibis, 1893, p. 328. 



Mr. Ferry was unable to procure a specimen of this fine Parrot 

 during his stay on Aruba, so I am unable to compare specimens from 

 the type locality with the series in this Museum from Blanquilla 

 Island; but Mr. Lowe (Ibis, 1909, p. 330) considers the Blanquilla 

 bird to be rothschildi, having compared his specimens from that island 

 with a series from Aruba including the type. 



According to Hartert's description (Ibis, 1893, p. 328) .4. roth- 

 schildi differs from A. ochroptera mainly in having only the anterior 

 part of the crown, the space around the eyes, and the ear coverts 

 yellow, and the green color of the throat reaches nearly or quite to 

 the lower mandible on sides of chin; the chin and throat are not 

 yellow as in ochroptera. In rothschildi the cubital edge of the wing 

 is largely bright scarlet, while in ochroptera it is yellow, with only a 

 few scattered red feathers near the body. The rump and abdomen 

 in rothschildi show less or no blackish edges to the feathers and the 

 abdomen is less distinctly tinged with blue. 



The measurements of 7 adult specimens given by Hartert are as 

 follows : 



Males, wing, 8 to 8.05; tail, 4.9 to 5.4; culmen, 1.26 to 1.4; 

 height upper mand. at base, .59 to .65. 



Females, wing, 7.80 to 8.30; tail, 5.1 to 5.3; culmen, 1.26 to 

 1.4; height upper mand. at base, .55 to .60. 



For further remarks concerning this species see under Blanquilla 

 and Margarita (pp. 223, 242). 



Conurus xanthogenius Bonap. 



13 specimens, 6 d\ 7 9 . 



Mr. Ferry informs me that this species is common on Bonaire. 

 The golden yellow crown will always distinguish adult birds in full 

 plumage from C. pertinax, and when compared in series it will be 

 noticed that the green of the upper parts is slightly darker. There 

 is much variation in the amount of yellow on the crown, probably 

 due to age and season. One male has a perfect yellow crown, 

 others, both males and females, have the crown yellow with a few 

 green feathers, the crown green with a few yellow feathers, and
