ON THE COURTSHIP OF THE GREAT CRESTED GREBE, 
. Head and neck in Shaking-attitude (ears erected vertically, ruff pear-shaped). 
. Shaking-attitude from behind. Note the curious shape of the lower part of 
the neck. 
. A pair in the Forward (exeited) Shaking-attitude. Note the head bent 
down, the neck strained forward; the slope of the body and cock of the 
tail are also very characteristic. 
. The Cat-attitude (Display). The general attitude is very well represented. 
More white should show on the breast; and the dark portion of the 
wings should be grey. ‘To represent them black lessens the effect of the 
real black on the crest, which in actual life is the central aud most con- 
spicuous part of the picture. 
. The Passive Pairing-attitude. Note the strange stiff appearance, the humped

back, and the total closure of the crest. 
Prare II. 
. The “ Ghostly Penguin” (attitude on emergence of the diving bird in the 
Display Ceremony). Note the head bent down, and the forward curve 
ot the top of the neck. 
. The same as fig. 9, side-view. Owing to the short time occupied in the 
action, Icamnot myself be sure that all the details in figs. 9 and 10 are 
accurate. The general appearance, however, is well given. 
. A pair shaking. Note the erect necks, and the tails slightly cocked up. 
. Display Ceremony : the diving bird just fully emerged. (This is the only 
tigure which is not satisfactory. It gives the positions etc. well, but does 
not recall reality in the vivid way done by the others.) 
. The Penguin Dance. Here again the whole ceremony takes such a short 
time that I cannot vouch for details; but the general appearance is very 
well suggested.
