strangers and put in own nest—attacked, 7 (about three of these Sir John 
did not feel sure); received amicably, 37. Pups brought up by strangers 
and put in strangers’ nest—attacked, 15; received amicably, 0. Sir John 
intends to make further experiments in this direction, but the above results 
seem very interesting. They appear to indicate that ants of the same nest 
do not recognise one another by any pass-word. On the other hand, if ants 
are removed from a nest in the pupe state, tended by strangers, and then 
restored, some at least of their own relatives are certainly puzzled, and in 
many cases doubt their claim to consanguinity. Strangers under similar 
circumstances would be immediately attacked. These ants, on the contrary, 
were in every case—sometimes, however, after examination—amicably 
received by the majority of the colony, and it was often several hours before 
they came across one who did not recognise them.—J. Muniz.

February 4, 1879.—Dr. GiintueEr, F.R.S., Vice-President, in the chair. 
The Secretary read a report on the additions that had been made to the 
Society’s Menagerie during the month of January, 1879, and called special 
attention to a Bar-winged Rail, Rallina peciloptera (Hartlaub), from the 
Fiji Islands, acquired by purchase; and to a young male Giraffe, Camelo- 
pardalis giraffa, received on deposit. 
Mr. Sclater exhibited and made remarks on a specimen of a Curassow, 
belonging to the Royal Museum of Copenhagen, which he had received 
from Prof. J. Reinhardt for examination, and which Prof. Reinhardt had 
proposed to refer to a new species, Mitua Salvini. 
Mr. R. Bowdler Sharpe exhibited a series of Bulwer’s Pheasant, Lobio- 
phasis Bulweri, from the Lawas River, N.W. Borneo, collected by Mr. W. H. 
Treacher, Acting Governor of Labuan. The series represented every stage 
of plumage of this Pheasant, and conclusively proved that L. castanei- 
caudatus, Sharpe, was the immature male of L. Bulweri. 
A communication was read from Prof. A. H. Garrod, containing some 
notes on certain points in the anatomy of the Hoatzin, Opisthocomus 
cristatus. 
Mr. Sclater read some notes on the breeding of the Argus Pheasant and 
other Phasianide in the Society’s Gardens. 
A communication was read from the Rey. O. P. Cambridge, containing 
the description of a new genus and species of Spiders, proposed to be called 
Fritzia Muelleri. 
Mr. W. Ottley read the first part of a series of observations on the 
structure of the eye-muscles in the Mammalia. 
A communication was read from Mr. Osbert Salvin on some birds
