﻿308 Mr. E. Hartert on the Birds of 



This Plover is common, and undoubtedly breeds, on Aruba 

 and Bonaire. I think it belongs to Ridgway's subspecies, 

 but that it deserves specific rank. Two adult males in very 

 fine plumage have no traces of a black band across the chest. 

 Lores decidedly rusty. Culmen 0"83 to 0'85 inch, wing 4*45 

 to 4*5, tarsus 1*1. 



The black band across the chest is probably always replaced 

 in the adult male by a rusty rufous band. 



30. H/Ematopus palliatus (Temm.). 



I only once saw a specimen of this Oyster-catcher on the 

 reef on Aruba and fired at it, but unfortunately missed it. 



31. Totanus flavipes (Gm.). 



This bird was common on Aruba on the 22nd June, when 

 Dr. Cole shot two specimens. 



32. Pelecanus fuscus, Linn. 

 Extremely common and not at all shy. 



33. Fregata aquila (Linn.) . 



Schlegel (Mus. d. Pays-Bas), Oates (B. Brit. Burm.)> and 

 others are of opinion that the white-breasted specimens of 

 this species are young birds, but Ridgway (B. N. Amer. 

 and Man. N. Am. B.) has already well described the plumage 

 of the adult female as well as that of the young, which has 

 the whole head white. My male example agrees perfectly 

 with specimens from the Pacific and Madagascar*. The 

 females have much larger bills than the males. My speci- 

 mens measure : — 



<$ ad. Aruba, 3 vii. Culmen 5'2 inches, wing 23*6, 

 tail 17. 



? ? ad. Aruba, 3 vii. Culmen 55 to 5'6 inches, wing 

 23 to 24'5, tail 15"5. 



34. Phalacrocorax brasilianus (Gm.). 



Great flocks of this Cormorant were seen on Aruba, but 

 were very difficult to approach. 



* Hartlaub ('Vogel Madagascar*,' p. 399) mentions only Fregata 

 minor from that island, but examples of both these very distinct species 

 have been recentlv received by the Tring Museum from Madagascar.
