and is even now used for it by the French, while in most other languages it has been transferred, from an early date, to the Antarctic flightless birds, the Spheniscidae.

All the first reports are from Newfoundland and thereabout, and even Clusius (Exoticorum libri decem, Lib. V, p. 103—1605), who gives a rather poor but perfectly recognizable figure, describes it first (p. 103) as a native of America, under the name of "Mergus Americanus." Later on, however, in the "Auctarium," on p. 367, he mentions it, on the authority of Henricus Hojerus, as found in the Faröe Islands, under the name "Goirfugel." Hojerus was also the authority for the account given in Nieremberg, Hist. Nat., etc., p. 215 (1635). The first comparatively good figure was published in 1655, in the "Museum Wormianum," on p. 301, from a specimen brought alive from the Faröe Islands. Curiously enough the figure shows a white ring round the neck, which no Great Auk, of course, possesses.

Linnaeus, when first bestowing a scientific name on the Great Auk, in 1758, l.c., gave the following short diagnosis and references:—

"Alca rostro compresso—ancipiti sulcato, macula ovata utrinque ante oculos. Fn. Svec. 119.
Anser magellanicus. Worm. mus. 300 t. 301.
Penguin. Will. ornith. 244 t. 65 Edw. av. 147 t. 147.
Habitat in Europa arctica."

From referring to the literature he quotes, there can, of course, be no doubt as to what species he refers.

The most detailed descriptions are probably those given in the New Edition of Naumann (see above), where also a list of literature and figures is given, fully seven folio pages long! As regards the difference in the sexes little is known, because very few specimens exist of which the sex has been ascertained. We find, however, some with the grooves and ridges on the bill more marked, and the grooves purer white, while others have the grooves of a dirtier white and less strongly developed; as these latter are apparently mostly smaller, I think they must be females, the former males. In this case my two specimens would be females, and the one now in Professor Koenig's possession an adult male. Probably somewhat similar seasonal changes took place as in Alca torda, and Professor Blasius (l.c.) has described them. It must, however, be remembered, that the date of capture is known of but a few examples, and that by far the majority of all those that exist in collections have been killed in spring, on their breeding-places.

Nobody can doubt that the Great Auk is extinct. The last specimens were obtained on Eldey, near Iceland, in 1844, and the seas and islands
