gallons an hour. The circulating machinery will be multiplied by four in 
one portion, and by eight in another portion, to secure adequate cur- 
rents at ull times, without interruption by accidents or other causes. In 
some of the tanks an automatic tidal-like arrangement will be attempted, 
the water in these receptacles rising and falling at intervals which may be 
varied at will. In fact, every improvement suggested by an experience in 
Aquaria extending over twenty-one years will be painstakingly carried out 
at Westminster. By the liberality of the Boards of Direction of both 
Institutions, I maintain my situation as manager of the Crystal Palace 
Aquarium, in conjunction with the same office at Westminster.—W. A.

The Secretary read a report on the additions that had been made to the 
Society’s menagerie during the month of October, and called, particular 
attention to a Gentoo penguin’ (Pygoceles teniatus), from the Falkland 
Islands, purchased October 22nd, being the first example of this species of 
penguin received alive, and a toothbilled pigeon (Didunculus strigirostris), 
from the Samoan Islands, deposited by Mrs. Boddam-Whetham, October 
23rd. [The penguin died on the 8rd of November, as already reported 
(Zool. 8.8. 4264).—E. N.] 
The Secretary exhibited on behalf of the Rev. J. S. Whitmee, an egg of 
Pareudiastes pacificus, and an accompanying egg of the Samoan Porphyrio, 
A communication was read from Sir Victor Brooke, containing some 
remarks on the identity of a certain deer in the Society's collection, which 
had been determined as Cervus Savannarum. 
A series of eggs of megapodes (Megapodius), transmitted by,Mr. John 
Brazier, was exhibited. These had been obtained from different islands of 
the Solomon group. 
Mr. R. B. Sharpe also exhibited some megapodes’ eggs from the southern 
part of New Guinea. 
Prof. Mivart read a paper on the axial skeleton of the Struthionide, and 
pointed out that, judging by the characters of the axial skeleton, the emeu 
presents the least differential type; from which Rhea diverges most on the 
one hand and Apteryx on the other ; that the resemblance between, Dromeeus 
and Casuarius is exceedingly close, while the axial skeleton of Dinornis is 
intermediate between that of Casuarius and Apteryx ; its affinities, however, 
with the existing New Zealand form yery decidedly predominating.
