424. SPHENISCUS MAGELLANICUS (Forst.).

(JACKASS PENGUIN.)

+Spheniscus magellanicus+, _Scl. et Salv. Nomencl._ p. 151; _Scl.

Zool. Chall. Exp._ pt. viii. (Birds), p. 125, pl. xxviii.

+Aptenodytes demersa+, _Abbott, Ibis_, 1860, p. 336.

_Description._--Above bluish black; broad superciliary stripe

descending on each side of the neck white: beneath white; throat and

sides of neck, and two breast-bands, the lower narrower and produced

down the sides of the belly, black; bill and feet plumbeous: whole

length 16·0 inches, wing 7·5, tail 2·0.

_Hab._ Coasts of Antarctic America and Falkland Islands.

At the mouth of the Rio Negro Hudson once picked up a specimen of a

Penguin, believed to have been of this species, which had apparently

just met its death by some accident. The range of this bird, moreover,

appears to extend much further north, as it is well known to the Gauchos

along the coast, who call it "_Pajaro Niño_" (bird boy), from its

fancied resemblance to a small human being when it stands erect on the

shore.

Darwin (Nat. Voy. chap. iii.) speaks of having seen numerous Penguins in

the estuary of the Rio de la Plata, when approaching Monte Video in

the 'Beagle,' in July 1832; and Graf v. Berlepsch tells me he has an

imperfect specimen of _Spheniscus magellanicus_ from the coast of Rio

Grande do Sul, where it was picked up dead.

The "Jackass Penguin" is a well-known species in the Falkland Islands,

to which it resorts in thousands for the purpose of breeding. Capt.

Abbott tells us it arrives at the latter end of September and commences

laying in its breeding-holes, almost to a day, on October 17. Some of

these birds, however, are found on the shores of the Falkland Islands

throughout the year.

Order XIX. CRYPTURI.

Fam. LIII. TINAMIDÆ, or TINAMOUS.

The Tinamous constitute one of the most singular and characteristic

types of the Neotropical avifauna. Until late years they were usually

associated with the Gallinæ or Game Birds, but differ very widely from

them in the conformation of the skull and in other essential points of

structure, and are now generally regarded as forming an Order of their

own, to be placed at the base of the series of Carinatæ. About forty

species of Tinamous are known, of which eight occur within our limits.
