NATURAL SCIENCES OF PHILADELPHIA. 201 



No. . . . Mus. Acad., Philada., male, adult, " Isles Croquets ;" 

 almost exactly like the preceding*; bill not quite so large ; stands 

 about 21^ inches high. 



No. . . . Mus. Acad., Phila., " Isle Macquarie." Young, or at 

 least imperfect plumage, the throat and sides of the head below 

 the eyes being white, slightly clouded with dusky, indicating the 

 blackish area of the mature state ; but the plumes are as largely 

 developed, the forehead is as yellow, and the bill is as large as in 

 the adults above mentioned. It seems to be exactly like spec. 

 No. 3 of Dr. Schlegel's catalogue, and is from the same locality. 

 This concurrence of white throat with intensely yellow forehead 

 is rather in favor of the validity of the species. 



These specimens appear to have stood a long time unrecognized 

 in the Academy, the richness of the ornithological department of 

 which only gradually appears. Thejrare unquestionably diadema- 

 tus. We are also pleased to identify with this beautiful species, 

 which seems strongly marked, and is at any rate recognizable on 

 sight by the orange forehead and other characters, a specimen 

 that has lain for some time in the Smithsonian, labelled " chryso- 

 lopha." It does not appear to be contained in the British Mu- 

 seum. Dr. Schlegel reports three examples at Leyden ; two 

 adults, one from the Falklands, the other from New Zealand ; and 

 an " individu a gorge et cotes de la tete blancs, du reste au plu- 

 mage parfait ; ile Macquarie, au sud de la Nouv. Zeelande." 



? A shade of doubt attaches, that this may be an extreme case 

 of chrysolopha ; for we have in the Eud. nigrivestis of Gould, 

 which is not distinct from chrysocoma, a state of plumage as dark 

 as that of diadematus. But diadematus is distinguishable on 

 sight, and no intermediate specimens have been forthcoming.
