ALLIED PETREL. 
The same year Finsch and Hartlaub {Faun, Centr. Polyn., p. 244, 1867) 
described their Puffinus dichrous as attached : — 
Ad. Supra fuliginoso -nigricans ; subtus albus, exceptis hypochondriis et subcaudalibus 
fuliginosis, his apice albis, lateralibus pogonis intemo albidis ; rostro nigro ; pedibus nigri- 
cantibus, membranis pallide brunneseentibus. 
Long. c. 11", al. 6"; rostro 11"'; caud. 2" 9"'; tars. 16"'. McKean’s Insel (Phonix- 
Gruppe). 
Two pages previously they had however recorded Puffinus nugax (Soland.) 
with which they synonymised P. assimilis Gould, and gave as habitats : East 
coast Australia, north-west New Zealand, Norfolk Island, Lord Howe Island, 
Christmas Island, Fiji and McKean’s Islands ! 
In the Ihis, 1869, p. 67, appeared the description of Puffinus elegans by 
Giglioli and Salvadori : — 
P. supra ex toto cinereo-plumbeus, plumis totis angustissime albo-limbatis ; tectricibus 
alarum mediis, majoribus, ac remigibus secundariis albo-limbatis, fascias tres trans alam 
formantibus ; subtus, tectricibus alae inferioribus remigibusque intus candidis ; capitis 
ac colli lateribus albo-cinereo-mixtis ; cauda brevi ex toto cinereo-plumbea ; tarsis postice 
nigris, antice caerulescentibus ; digitis subtus nigris, supra caerulescentibus, palamis albidis, 
unguibus nigris ; rostro tenui, caerulescenti, culmine et apice nigris ; iride brunnea. 
Long. tot. 0.320, alae 0.190, caud. 0.075, rostr. a fronte 0.027, hiatus 0.037, tars. 0.040, 
dig. med. cum ung. 0.049. 
Hab. South Atlantic, Lat. 43° 54'S. Long. 9°20' E. 
These authors compared their bird with P. munda Kuhl, but complained, 
quite correctly, that there was not much to go upon in the matter of Kuhl’s species. 
It might be remarked that up to this time no one seems to have considered 
the probability of birds, coming from different localities, being separable. This 
bird (P. elegans) was procured in the South Atlantic (lat. 43° 54' S., long. 9°20' E.) 
while P. munda was killed in the South Pacific (lat. 48°27' S., long. 93° W.) ! ! 
In the Proe. Zool. Soc. (Lend.), 1872, Hartlaub and Finsch reviewed this 
group, and introduced a new form as follows : — 
p. Ill] Puffinus auduhoni, Berlin Mus., from Cape Florida {=flondanus Bonap., Consp. Gen. Av., 
II., p. 204). 
Like P. assimilis, but the under tail-coverts fuliginous -black ; the anterior lateral under 
tail-feathers are on the outer vane black, on the inner white ; the white on the sides of the 
head extends, as in P. assimilis, not below the level of the eyes ; bill deep leaden-blue ; feet 
and legs coloured as in P. anglorum. 
Their description of P. asshnilis on the same page reads : — 
Like P. obscurus, but smaller ; the under tail-coverts also uniform white ; but the white 
of the under-parts mounts upon the sides of the head, including loreal and auricular regions ; 
tarsi greenish-yellow, webs bright chrome-yellow. 
In the Pacific seas of Australia and New Zealand. 
Puffinus obscurus was restricted by them thus : — 
“ This species, black above, white beneath, may be distinguished at once by the uniform 
white under tail-coverts . . . inhabits the Indian Ocean (Christmas Island, Latham ; 
Madagascar, Bourbon, Mauritius, V err.” [It will be noted that Hartlaub and Finsch confused 
Christmas Island in the Pacific Ocean with Christmas Island in the Indian Ocean.]
