eggs, and have nearly exterminated a colony of Penguins on the 
south side of the island, the few birds that remain “ having learnt 
to build in holes under stones, where the pigs cannot reach 
them.” This is curious enough, although not an isolated case. 
The Didunculus, or Little Dodo, of Samoa, was originally a 
ground-nesting species, but to escape its enemies, chiefly domes- 
ticated animals introduced by Europeans, it has learnt to build 
in trees, and so for a time at least has escaped extinction. 
It seems remarkable that there should be only one species of 
Penguin, Hudyptes saltator, at the Tristan da Cunha group, 
since in most localities where these birds are found several species 
occur. One would have expected to find some representative of 
the genus Spheniscus there, since one species, S. magellanicus, 
occurs at the Falkland Islands and Fuegia, and another, 
S. demersus, at the Cape of Good Hope, intermediate between 
which two points lies Tristan da Cunha. The connection between 
these two widely separated Sphenisci is wanting. Mr. Moseley 
suggests ‘‘it perhaps once existed at Tristan, and has perished.” 
The Teal of Kerguelen’s Land is peculiar to that island 
and to the Crozets. Mr. Sharpe not long since described it as 
Querquedula Eatoni. It is somewhat larger than our common 
Teal, of a brown colour, with a metallic-blue streak and some 
little white on the wing. It is extremely abundant about Ker- 
guelen’s Land near the coast. Mr. Moseley killed twenty-seven 
in one day, and similar bags were frequent. Four or five guns 
used to bring back usually over a hundred birds. ‘These Teal 
feed mainly on the fruit of the Kerguelen cabbage, and are 
extremely good eating. Until they have been shot at repeatedly 
they are very tame, and require to be almost kicked up to afford 
a shot. At one valley, near Three Island Harbour in Royal 
Sound, which had probably not been visited by man for thirty or 
forty years, a flock of these Teal rose about a hundred and fifty 
yards from the author, and, instead of going further away, flew 
towards him, and, alighting on the ground within forty yards of 
where he stood, commenced running still nearer to him, impelled 
apparently by curiosity. Of course many of them paid the usual 
penalty, for, as Mr. Moseley says, “only those who have been 
long at sea know what an intense craving for fresh meat is 
developed by a constant diet of preserved and salt food.” 
At p. 154, Mr. Moseley describes an Otter of which we do not
