BEOWN-HEADED PETEEL. 
Though I had many times examined the Banksian drawings I had never 
noted the name melanopus on any, so I made another search, without success. 
It was this note of Natterer that instigated the persistent inquiry which led 
to the recognition of the Solander MS. dealing with the Petrels, and the 
description of Procellaria inelanopus Solander is here given : — 
melanopus Procellaria nigricanti-fusca subtus pallidior, cauda rotundata nigrieante, pedibus 
totis atris

The first locality given is due south of Easter Island, the second close to 
Pitcairn Island, the third off the Kaipara, North Island of New Zealand, and 
the fourth in the Tasman sea approaching Bass Strait. 
The first two examples would seem to be referable to some dark form of 
Pterodroma, perhaps P. neglecta Schlegel, or maybe some other at present 
undescribed bird breeding about Easter Island or Pitcairn Island. The sbeond 
two appear to have been specimens of P. ^nacroptera gouldi Hutton, though to 
that bird the words “ Eemigibus primoribus basi intus albidis ” do not apply. 
It should be noted that the fourth locality is quite close to the type-locality 
of Gould’s P . solandri, but the distinctive mottling round the base of the bill
