The unique example of this species having been lost, I am unable to introduce a figure of it in this work. I append the original
description by Mr. L awrence.
“ Head and wings black; neck, breast and back, dark plumbeous, or dull bluish-ash; wing coverts brown, the tail white at the base,
with the terminal half and the two central feathers black;■ abdomen, inside covering of wings, and rump, white; bill and legs black;
Tail even, claws flattened and of an oval form.
“ Length, about 8 inches; wing, 6; tail, 3; tarsus, II. Habitat, Florida coast."

I have never seen this bird, and the unique example, like the preceding, appears to be lost. Dr. Coues’ diagnosis is as follows:
“ P . Puffini major is slalura, nec ei color I bus perdissimilis ; sed rostro multo breviore, crassiore, lubulis nasalibus inflatis; fere omnifto nis:
ungue jlavescenle cameo; pedibus brevioribus, gracilioribus, camels; tectricibus caudce superioribus et infcrioribus ex loto brunnco nigris,
remigibus primariis spatio albo basin versus interni pogonii carcnlibus.
Habitat. Specimen typicum et unicum ex insuM “ San Nicholas” prope California.
Length, 19.00; extent of wings, 45.00. BUI along culmen, 1.60; gape, 2.30; from feathers on side of lower mandible, 1.50;
height at base, .60; Nasal tubes .40; wing from flexure, 12.50; tail, 5.00; tarsus, 2.10; middle toe and claw, 2.65.

This species, an engraving of the head o f which is hero given of the natural size, resembles somewhat the P. Anglorum, but is
much smaller than that Species, and has o th e r marks of difference. Coues’ diagnosis is as follows:
P. Piiijino obscuro nec perdissimilis; sed major, rostro longiore, robustiore, alls pedibusque longioribus, cauda breviore, minus rolundala;
et tectricibus cauda: inferioribus fere omnino fuliginoso-nigris.
Habitat. South Pacific coast of North America. The specimens were obtained by Mr. Xantus at Cape St. Lucas. BUI along culmen,
1.40; commissure, ■ 2:00; height’a t base, .42; wing from the carpus, 9.00; tarsus, 1.80;; middle toe and claw, 2.10; tail, 3.75.

It is not a very easy matter to always distinguish the various species of “ Black Puffins,” as they naturally closely resemble each
other, and give the impression, that although we can consider them as having received their full- growth, still they may not have as yet
assumed the adult livery, and therefore only bo in a certain stage of plumage incidental to the corresponding bicolor species.

This bird was characterised as distinct by Mr. L awrence, who formed his opinion upon two immature specimens. Since his
description was published, many examples have been received at the Smithsonian Institution, from various collectors in Arctic America,
in all stages of plumage; and, judging from these, it does not appear to be distinct from C. Arclicus. The color and style of markings
are precisely similar, and although the bill in some examples is weaker and more slender, yet this member varies very materially among
individuals from the same locality.
