I SEPARATED this genus as follows : 
“ Differs from Puffinus in its proportionately longer bill and much 
shorter tail, the latter being less than one-third the length of the wing 
and not twice the length of the exposed culmen.” 
Iredale {Austral Av. Rec., Vol. II., No. 1, p. 17, Ai%. 2, 1913) added; 
“ The bill is ‘ puffinoid ’ in character, as exemphfied m the figures given by 
Mathews {Birds of Australia, Vol. II., 1912, p. 130), but is pecuhar in its 
extreme length and weak nail ; in the fully downy nestling the exposed 
culmen measures 30 mm., while in the fully adult it only measures 35 
mm., the difference may be best expressed by comparison with the young 
of P. assimilis gavia, where the bill in the fully downy nestling only 
measures 16 mm. against that in the adult of 27 ; the nail in the downy 
nestling is just one-third the length of the culmen, whereas in P. a. 
gavia it is about one half, a difference in proportion which constitutes a 
great distinction in this group.” 
More observations on bill features of downy birds are required before 
the full value of such records can be fairly utihsed, but the shortened tail 
of this species in conjunction with the lengthened bill justify the retention 
of this generic group. And Hull, as above, also made a new genus for 
this species.
