2. DESCRIPTION OF THE EGG OF PARRA GALLINACEA. 
By Joun Govutp, F.R.S. &e. 
The ground-colour of the egg of this species is of a dark shining 
raw-sienna tint, over which are traced in various directions a series 
of broad and fine hair-like contorted lines of brownish black, which, 
by occasionally uniting laterally and crossing each other, form here 
and there large blotches. Although these markings are of the same 
character on each egg, they are somewhat differently distributed : 
thus, on one of the two I possess, they are more numerous at the 
larger end, and absent at the smaller; while, on the other, they are 
more abundant at the smaller, and less so at the larger extremity. 
The eggs are one inch and an eighth in length by seven eighths of an 
inch in breadth. They are, moreover, rendered remarkably conspi- 
cuous by the singularly pointed form of the smaller end, and by their 
small size as compared with that of the bird, but above all by the 
form and disposition of the markings, which are as if traced by the 
hand of a person who had amused himself by attempting to cover the 
surface with fantastic streaks, blotches, and contorted curves from 
end to end. 
The two examples above described were most kindly sent to me 
from Eastern Australia, by Mr. Hills, through the instrumentality of 
his relative, Sir Daniel Cooper, Bart. 
3. CHARACTERS OF NEw SPECIES OF CRUSTACEANS DISCOVERED 
BY J. K. Lorp on THE Coast or VANCOUVER IsLAND. 
By C. Spence Barr, F.R.S. 
[The following new species of Crustaceans, collected on the east 
side of Vancouver Island, were kindly named, described, and figured 
for me by Mr. Spence Bate. Some of them were dredged in from 
8 to 10 fathoms of water ; the rest were collected between tide-marks. 
Mr. Spence Bate says, in speaking of the collection generally, 
«‘The extremely opposite and varied localities in which many of the 
species here represented have hitherto been found, suggest the idea 
that Vancouver Island corresponds with the extreme limit between a 
northern and a tropical fauna.” ‘‘ It is only in this way I can account 
for finding the representatives of tropical species, with others that are 
found only (on the eastern coast of Asia) in the Arctic and, perhaps, 
North Atlantic Oceans.” That he is quite correct im this assumption 
I think there can be little, if any, doubt ; for not only does it apply 
to the Crustaceans, but with equal force to the Molluscous groups, 
Several new species of shells, collected at the same time and in the 
same localities as the Crustaceans, which were named and described 
by Dr. Baird, with appended notes by myself, and published in the 
Society’s ‘ Proceedings’ of last year, are identical in some cases, in 
others closely allied to known species from Japan, Australia, and the 
north shores of our own island. 
The tidal irregularities of this coast are perfectly inexplicable. In
