Knobbed-billed Phaleris

Knobbed-billed Phaleris [now Least Auklet]
Phaleris nodirostris, Bonaparte [now Aethia pusilla]
Octavo edition, plate 468

“This bird, which at first sight bears a considerable resemblance to the Little Guillemot, Mergulus alle, I have also represented from a specimen belonging to the Zoological Society of London. The following description, however, is taken from one in my own possession. The species is said to occur on the north-west coast.”
