In the preparation of this report I have confined myself to a careful study of the 
nestlings and embryos, and to certain hitherto undescribed, or wrongly interpreted 
points concerning the pterylosis of the adults of the Emperor and Adélie Penguins ; 
and this partly from choice and partly from necessity, since no complete adults in 
spirits formed a part of the collections brought home. Even had such specimens been 
preserved they could have added but little of importance to our knowledge of these 
remarkable birds. Thanks to the able monograph of Prof. M. Watson, which formed a 
part of Vol. VII. of the great series of volumes published on the results of the 
‘Challenger’ expedition of 1872-76, we may be said to have a fairly complete know- 
ledge of the general anatomy of the adult penguin, though much yet remains to be 
done from the systematist’s point of view. Therein, at any rate, will be founda survey 
of the anatomy of nearly every genus, most of which holds good to-day, though in 
some particulars further research or better material have reversed conclusions therein 
expressed. In the memoirs of Prof. Menzbier (9), Schaunisland (14) and Studer (16), 
will be found much valuable matter with regard to the development of the penguin,
