Dr. J. E. Gray, V.P., in the Chair. 
Mr. Sclater exhibited some bird-skins, procured by Capt. Herd at 
Port Churchill, Hudson’s Bay. Amongst them was a Crane, similar 
to Grus canadensis, but much smaller in dimensions, and probably 
referable to the species described by Mr. Cassin as Grus fraterculus 
(Birds of N. Am. p. 656) from an immature example obtained in 
New Mexico. It was of interest as being the second specimen ob- 
tained, and the first in adult plumage, of this species. Another skin 
was probably that of Bernicla hutchinsii, though rather larger in di- 
mensions than the described individuals of this species. Capt. Herd 
had likewise presented a living pair of this dwarf variety of the Canada 
Goose ( Bernicla canadensis) to the Society’s Menagerie—which was 
the first occasion of their having been exhibited alive in this country. 
Mr. Gould brought under the notice of the meeting several Crested 
Penguins, and remarked that there appeared to be some species of 
this truly oceanic group which had not yet been characterized. Upon 
the present occasion, however, he only referred to those forming the 
genus Ludyptes, and, after a few cursory observations upon the de- 
scribed species of that form, proceeded to characterize two others from 
his own collection under the names of Hudyptes nigrivestis and E. 
diadematus. 
Mr. Gould remarked that the species of this well-defined crested 
group now known were :— 
Eudyptes chrysolophus. Eudyptes nigrivestis. 
chrysocome. —— diadematus. 
pachyrhynchus. 
The following were the descriptions given of the two new spe- 
cies :— 
EuDYPTES NIGRIVESTIS, Gould. 
Face, chin, upper part of the throat, and sides of the neck black ; 
feathers of the forehead and crown long, narrow, and silky-black ; 
those on the sides of the head considerably prolonged ; a stripe of pale 
straw-yellow commences at the nostrils, continues over the eye, and 
extends in lengthened narrow filamentous feathers behind that organ; 
upper surface black, each feather with a narrow line of greyish-blue 
at the tip; outer side of the wing shining black, edged posteriorly 
with white ; tail black with grey reflexions; all the under surface of 
the body and the under surface of the wing, except at the base and 
tip, silky-white, the base and tip being sooty-black ; bill chestnut- 
brown; eye pinkish-chocolate ; feet livid. 
Total length 211 inches, bill 2, wing 53, tail 4, tarsi Z. 
Habitat. The Falkland Islands, where it is known by the name of 
«* Rock-hopper.””
