DISTRIBUTION. Straggler to Tasmania and South Australia ? See Emu, Vol. XVI., pt. 3, 

 p. 184, Jan. 1917. 



Adult male. As of general Penguin coloration, but differing from the preceding 

 in being a smaller bird, with generally paler coloration above, while the throat and 

 cheeks are dark slaty or grey -black, showing a great contrast with the black of the 

 top of the head. The crest is different being composed of long flowing black and 

 yellow feathers mixed, beginning as a thin yellow line on the lores, and apparently 

 capable of lateral erection. The bill is shorter and more slender. Bill red ; iris 

 rich brown ; toes and tarsus pinkish -white. Total length unknown (according to 

 stuffing in skins) ; culmen (exp.) 37 mm., flipper 130, tarsus 25, middle toe and 

 claw 60. 



Adult female. Similar. 



Immature and Nestling. Undescribed from Neozelanic localities. 



Nest. None made. 



Eggs. Clutch, two ; bluish-white ; 75-80 mm. by 45. 



Breeding -season. October. 



Distribution and forms. Round the Sub -antarctic Circle. We are accepting the 

 Falkland Islands birds as typical, as the name E. serresiana was given to an immature 

 specimen, and we now name the following subspecies which have been distinguished 

 in literature for many years : E. s. mosdeyi subsp. nov., from Inaccessible Island, 

 Tristan d'Acunha Group, with a longer bill, and a very long crest, very pale ashy 

 throat and generally light upper coloration ; E. s. interjectus subsp. nov., from 

 Kerguelen Island, with a shorter bill and darker throat and less developed crest 

 and apparently smaller size ; and E. s. filholi Hutton, from Campbell Island, New
