PODICEPS LEUCOPTERUS. 



Pod. capite coUoque svperioribus nigris, guld griseo-albiddy collo in- 

 Jeriore riifo; dorso fusco-atro ; abdomine strigdque laid alarum albis. 



The red patch that marks the fore neck of this bird is of a deep colour, 

 and is strongly defined above, where it terminates in a square form at the 

 distance of about two inches and a half from the base of the lower man- 

 dible. Below it is less abruptly terminated, the red feathers blending 

 into the white and partially running down the sides of the abdomen. The 

 first quill feathers are fuscous at their extremities and white at their base, 

 which latter colour increases in the succeeding primaries, and prevails in 

 the outward secondaries, but is gradually lost in the more internal ones. 

 Underneath the quill feathers are chiefly white with a fuscous base ; the 

 under wing coverts are entirely white. The bill is black, light coloured 

 at the tip : the legs are black. The length of the body is 20 inches; of 

 the bill 3 ; of the wing, from the carpal joint to the apex of the second 

 quill feather, 7J; of the tarsi, 2. 



62. A young bird, I think of the Aptenodytes chrysocome. The 

 yellow feathers are beginning to show themselves on the sides of the 

 head. 



63. A species of Corvorant, nearly quite black, which I make little 

 doubt is that mentioned by Azara as the black Zaramagullon, (No. 432 

 of his Birds of Paraguay.) The description accords very closely with my 

 bird, except in a few trifling particulars relating to the bill. As I am 

 not aware of the bird having received a scientific name, I shall describe it 

 under that of 



PhALACROCORAX NIGER. 



Phal, intense niger, circulo angusto ab oculis descendente, mandibti- 

 lasque circumcingente, paucisque genanim capitisque plumis albis. 



The circle of white which margins the bill, does not extend to the 

 front of the head. The narrow white feathers are rarely spread on the 

 sides of the head and neck: the number and extent of these probably 

 vary according to the age of the bird and the season of the year. The 

 feathers of the upper part of the back, scapulars, and upper wing coverts
