438 Hans von Berlepscli 07i Bird-skins 



This is certainly qnite an old bird ; the naked head appears 

 of a uniform yellowish or orange colour. On the sides of the 

 neck and the occiput small lobes, or caruncles are disposed, 

 a peculiarity which I do not believe ever occurs in true 

 C. aura ! The shafts of the primaries are yellowish white 

 above and below. 



This species w^as not previously known to occur in Vene- 

 zuela. 



27. Cathartes atratus (Bartr.). 

 Angostura. Four specimens, old and young. 



Long. al. 395-420, caud. 170-180, culm. 25-28^, tars. 

 75-80 millim. 



The very old bird has the skin of the head, especially on 

 the hind neck, extremely corrugated and folded ( j ust as re- 

 presented in d'Orbigny^s Voy. Am. merid. Ois. pi. i. fig. 1), 

 while the young one has it nearly smooth. 



28. Ardea cocoi, Linn. 

 Angostura. A young bird. 



Long. al. 448, caud. 180, culm. 130^, tars. 185 millim. 

 The dimensions are much smaller than those of my birds 

 from Southern Brazil. Species new to the fauna of Venezuela. 



29. Ardea candidissima, Gmel. 



Angostura. One specimen lacking nuptial feathers of the 

 neck and lower back. 



Long. al. 252, caud. 90, culm. 85, tars. 93 millim. 



Base of maxilla yellow ; legs and feet greenish brown, not 

 marked with yellow. 



A specimen from Guiana in Mus. H. v. B., in full nuptial 

 plumage, differs in being much smaller and in having the 

 feet of a yellowish colour. I am not prepared to say 

 whether these differences are sexual or otherwise. 



30. Ardea sibilatrix, Temm. 

 Bio Apure. An old bird. 



Long. al. 312, caud. 119, culm. 70^, tars. 90 millim. 



Agrees with specimens from Bio Grande do Sul, Brazil 

 (Mus. H. v. B.), but is of somewhat larger dimensions, 

 especially the bill is longer and broader at base. The upper
