Adultfemale. — Similar to the adult male and apparently not always 

 distinguishable but usually with coloration slightly duller, the fore- 

 head, neck, and chest less vinaceous (the latter more often pale 

 vinaceous-drab), and metallic reflections on hindneck less often (?) 

 purple, usually ( ?) bronzy or bronze-greenish; length (skins), 245-288 

 (268); wing, 129-143.5 (135.3); tail, 94-109 (101.9); exposed cul- 

 men, 15-17.5 (15.9); tarsus, 25.5-29.5 (27.3); middle toe, 20.5-25 

 (23.2). 6 



Apart from their shorter wing and tail, I can see no difference between examples of 

 this species from Margarita and other islands off Venezuela and mainland examples; 

 and considering the great range of individual variation in measurements I do not 

 think the supposed island form (L. v. insularis) worth recognizing. A larger sories of 

 island specimens might, however, prove the supposed form to be valid.' Specimens 

 from the interior of Venezuela are appreciably darker, and may require subspeciflc 

 separation.
