﻿300 Mr. E. Hartert on the Birds of 



13. Conurus arubensis, Hartert, Bull. B. O. C. iv. p. xvi 

 (1892). 



Adult male and female. Forehead pale yellow for about 

 0*3 inch; top of the head distinctly tinged with blue; 

 circle round the eyes very narrow above, broader below, 

 pale orange-yellow; lores, cheeks, and sides of the head 

 mixed light brown and very pale orange-yellow, the feathers, 

 especially those on the ear-coverts, being yellowish in the 

 middle and bordered with brown; throat and upper breast 

 yellowish brown. Of the same size as Conurus muginosus, 

 but tail longer as a rule. 



This form of Conurus is closely allied to C. eeruginosus 

 from Guiana and Venezuela, from which it differs only in 

 the lighter colour of the forehead, sides of the head, and 

 throat, and I believe also in a somewhat longer tail. As my 

 four specimens from Aruba differ in these points from nine 

 skins from British Guiana in Mus. W. Rothschild, from all 

 the skins from different localities in the British Museum, 

 and from skins from Venezuela in Mus. H. v. Berlepscb, I 

 believe I am right in distinguishing it as a new island form. 



<$ sect. Aruba, 22 vi. Iris straw-yellow ; bill horn- 

 brown; feet deep brown. Total length 9'7 inches, wing 5 - 3, 

 tail 4*9, culmen 0"9, tarsus 0*5. 



$ sect. Aruba, 23 vi. Iris pale yellow. Total length 

 about 9'6 inches, wing 53, tail 5*1, culmen 0'95, tarsus 0*5. 

 $ ad. sect. Aruba, 2 vii. Vv r ing 5 - l inches, tail 4*85, 

 culmen 0*85. 



£ ad. sect. Aruba ; 2 vii. Wing 5 "45 inches, tail 4*9, 

 culmen 0*78. 



In fifteen specimens of C. ceruginosus from Guiana and 

 Venezuela the tail measures 4*25 to 4 - 6 inches, the wing 

 5*3 to 5*65, the culmen 0*85 on the average, In Salvador's 

 description (Cat. B. xx. p. 196) the length of the bill is given 

 as 0"28, which is evidently a misprint for 0'78 or - 88. 



Conurus arubensis might, on account of its somewhat 

 yellowish sides of the head, be looked upon as a form inter- 

 mediate between the continental C. ceruginosus and C. per- 

 tinax from Curacao and St. Thomas. To those naturalists
