under wing-coverts along the edge of the wing mostly black. 

 Salvin has stated that the upper parts in (E. cervicalis are 

 " much darker" than in (E. externa', but our present series 

 shews that this is not really the case, as some birds from 

 the Kermaclecs have the upper parts perfectly similarly 

 coloured to the type from Masafuera Island, on the coast of 

 Chile.

The colour of the under parts of three adult birds varies 

 considerably: one has the throat, neck, &c. sooty; the second 

 specimen has these parts brownish-grey ; while in the third 

 they are whitish, tinged with grey. The young bird is 

 much lighter in colour than the adult, and has the under 

 parts mostly white, the feathers of the cheeks and throat 

 being edged with dusky, while some of the breast- and Hank- 

 feathers are similarly fringed with dusky. 



In all phases of plumage, even in the most dusky, this 

 species may be distinguished from the sooty - coloured 

 CE. macroptera by having the shafts of the primary-quills 

 mostly white, Avhile in the latter they are dusky to the 

 base ; the bill, moreover, in the present species is much 

 smaller, the nail especially being less developed than in 

 (E. macroptera.

The Blaek-winged Petrel was originally described by 

 Mr. Rothschild from specimens procured at the Kermadec 

 Islands, and the present examples are similar to two of 

 the typical specimens presented by that gentleman to the 

 British Museum.
