Fresh-Water Entomostraca from Island of Mull. 329 
Chydorus globosus, Baird. 
There are very few Scottish records for this fine species, 
and they are all from the west side; the localities to which 
these records refer are Paisley Canal (Robertson and T. 
Scott); the Hebrides (Rev. A. M. Norman); Lismore Island, 
Argyllshire (T. Scott). 
Bythotrephes longimanus, Leydig. 
This curious Crustacean, with its enormously long post- 
abdominal spine, would seem to be widely, if not generally, 
distributed in Scotland. I have obtained it in Loch Leven, 
Kinross-shire, and in Loch Ness and Loch Morar, Inverness- 
shire. Its occurrence in the Mull lochs is a further extension 
of its distribution on the West Coast. 
XXIV. The Penguins of Erebus and Terror Gulf. By C. W. 
; DOoNALD, M.B., C.M. 
(Read 21st February 1894.) 
During the late Antarctic expedition by the Dundee 
whalers, we met with four species of penguins in the neigh- 
bourhood of Erebus and Terror Gulf, viz.—(1) The Emperor, 
Aptenodytes Fosteri (G. R. Gray); (2) Pygoscelis Adelie 
(Hombron and Jacquinot), and Dasyrhamphus Herculis 
(Finsch); (3) Pygoscelis Antarctica (Forst.); and (4) The 
Johnnie or White-headed Penguin, Pygoscelis taeniata (Peale). 
The Emperor penguin we saw swimming on one or two 
occasions in lat. 63° S. Several were again seen on ice-floes 
to the south of 64°, and again in the north of the Erebus and 
Terror Gulf, directing the motions of schools of smaller 
penguins. 
Dr Sclater, in speaking of this bird,’ says that it has been 
met with on three previous occasions: by Cook in 1774-75, 
by Ross in 1840-45, and by the United States Exploring 
Expedition in 1840. Weddell and others must, of course, 
have seen it, but brought no specimens home, and could not 
distinguish it from its near ally, the King Penguin.
