orange-yellow patch on each, side of the head, shading gradually 

 into white on the neck ; a wide blackish band bordering the 

 shoulder, and ending in an obtuse point partially divides the white 

 sides of the neck ; fore-neck and rest of underparts white ; upper 

 surface of flippers like the back, under surface pure white. Tail 

 composed of 20 feathers, which scarcely exceed the longer upper 

 tail-coverts in length. Inter-ramal space entirely feathered ; greater 

 part of the basal half of the lower mandible feathered, leaving only 

 the expanded and coloured edge naked at the gape. Tarsi covered 

 with feathers which conceal the base of the outer toe. Total 

 length about 48 inches ; culmen from gape 4-5, from feathering on 

 nasal opening to tip 2 ; flipper, from shoulder to tip 12-6-12-9 ; 

 tail 3-6. 



McCormick records the weight of one of the adult specimens 

 obtained by him as 64| lb. Donald records two birds weighing 

 respectively 74 lb. and 60 lb. ; the vertical height of the latter was 

 45 inches, the greatest circumference 37| inches, and the length 

 from tip to tip of the flippers 36i inches. E,oss gives the weight as 

 60-78 lb. 



Immature. Differs from the adult in its smaller size and in 

 having the semi-circular patches on the sides of the head whitish, 

 with only the slightest trace of yellow ; chin and throat white,

* In spite of what G. E. Gray has written to the contrary [Ann. Mag. N. BT. 

 xiii. p. 315 (18-14)], there oanuot bo the slightest doubt that the Aptenodi/tes 

 patagonira figured in Miller's ' Cimelia Pbysiea,' pi. sxiii. (ITOfi), is the same 

 species as the bird figured by Pennant, Phil. Trans. Iviii. pi. v. (1768). 



Miller's figure is of course wrongly coloured, the upper parts being painted
