NOTE ON THE ILLUSTRATIONS. 



Plate VIII. represents the heads of four stages in the growth of this penguin, three of which 

 Figs. 1, 2, 3 are reproduced from sketches made upon the spot of birds that had just been 

 killed. Fig. 4 is drawn from a remarkable skin in the collection of the British Museum taken in the 

 Snares Islands. As I could not ascertain that such an example had anywhere been previously iigured, 

 I. asked permission to figure it with those of our own collection. This permission Dr. Ray Lankester 

 kindly gave me. The skin is probably that of a very old and vigorous male bird, and possesses points 

 which are worth more than a passing notice.
