These specimens agree well with those from Para. 



In the young male the primary coverts are green, but oue of the bastard-ijuills 

 shows already the orange colour of the adult plumage. 



74. Strix flammea subsp. 



No. 554. ¥ ad., Urncurituba, 8. ii. 06. " Iris brown." 



A very large, fine specimen, which does not quite agree with any of the 

 neotropical forms, of the Barn Owl. Very likely it represents an undescribed 

 subspecies, but it would be not scientific to describe it from a single example. 



75. Busarellus nigricollis (Lath.) 



Fako nigricollis Latham, Ind. Orn. i. (1790) p. 35 ("Cayana"). 

 Busarellus nigricollis Riker & Chapman, Auk, 1891, p. 161 (Santarem). 



No. 549. ¥ ad., Urncurituba, 8. ii. 06. " Iris brown." 



70. Elanoides furcatus (Linn.) 

 Falco furcatus Linnaeus, Sysl. Nat. xii. 1. p. 120 (1766.— ex Catesby & Brisson : Carolina). 

 No. 560. S ad. Urucuritnba, 9. ii. 06. " Iris brown, feet grey." 



77. Hoplopterus cayanus (Lath.) 



Charadrius cayanus Latham, Ind. Orn. ii. (1790) p. 749 (ex Bufllon and Daubenton : " Cayaua "). 



No. 551. ¥ ad., Urucuritnba, S. ii. 06. " Iris brown, feet reddish yellow, bill 

 black." 



Apparently not before recorded from the Lower Amazons, though Natterer 

 collected specimens near Mauaos. 



The record of the African Hoplopterus spinosus from the Capim River, Para,* 

 is, of course, a mistake. 



78. Carbo vigua (Viell.) 



Hydrocorax ulgua Vieillot, Noun. Dirt, viii. (1817) p. 90 (ex Azara : Paraguay). 



No. 584. S ad. in nuptial plumage, Urncurituba, 26. ii. 06. " Iris light blue, 

 bill black, below greyish white." 



II. BIRDS FROM OBIUOS. 



1 . Thryophilus albipectus albipectus (Cab.) 



Cfr. supra, p. '2. 



No. 589. c? in moult, 12. iii. 00. " Iris grey-brown, feet light bluish grey, bill 

 greyish black." Quite as pale on the lower parts as Cabanis' type from Cayenne. 



2. Dacnis cayana cayana (Liim.) 



Vide Nov. Zool. xiii. p. 356. 



No. 646. S ad., 20. iv. 06. " Iris reddish brown." Wing 63 ; tail 42 mm. 



In size, and in the deep black colour of the throat, this bird agrees with others 

 from Cayenne, Para and the Caura valley. Specimeus from Ueara, Bahia and 

 Pernambuco are also perfectly similar.
