Gould's figure is excellent, but the light feet are probably liable to 

 become dark in some specimens, and I am even disposed to credit the 

 assertion of Latham, that some of these birds have red feet and are 

 occasionally marked with black on the toes. Several of the speci- 

 mens in our collection though much faded, show the reddish tinge quite 

 distinctly, and one only has the feet so light colored that they approx- 

 imate to the variety figured by Gould. Latham also remarks that 

 the absolute size and color of the feathers vary exceedingly on the 

 back; this indicates that Spheniscus undina of Gould is only a small 

 sized, perhaps more or less localized variety of Spheniscus minor, 

 if, indeed, it be anything more than a young bird. The wings are 

 white below with only a small spot of penguin blue at the tip. 



A young specimen from New Zealand has an imperfect collar 

 formed by lines of dark brown feathers which cross the throat. The 

 bill is shorter and rounder, not flattened on the sides or so deep as in 

 the adults. At a still earlier period, when the true feathers begin to 

 replace the down, there are no tail feathers. These are grown subse- 

 quently, though very short, and are thicker and stiffer in some speci- 

 mens than in others. The longest and thickest shanked feathers 

 occur in the young specimen from New Zealand, described above. 

 There are only one or two scutella on the toes at the bases of the 

 nails.
