16th January, 1883. — The Secretary read a report on the addi- 
tions that had been made to the Society's Menagerie during the month of 
December. — Mr. H. E. Dresser, F.Z.S., exhibited and made remarks on 
a specimen of Merops philippensis, which was said to have been obtained 
near the Snook, Seaton Carew, in August 1862. — Lieut.-Colonel God- 
win-Austen, F.R.S., read the third and concluding of a series of papers 
on the shells which had been collected in Socotra by Prof.J. Bayley Balfour. 
The present portion treated of the freshwater shells of Socotra, which were 
stated all to belong to the genera Planorbis, Hydrobia, and Melania. Not a 
single bivalve was obtained. Four species were described as new, namely, 
Planorbis socotrensis, P. Cockburni, Hydrobia Balfouri, and Melania Sclateri. — 
Prof. E. Ray Lankester, F.R.S., read a paper on the right cardiac val- 
ves of Echidna and of Ornithorhynchus. Seven additional specimens of the 
latter animal had been examined since the author’s former paper on this 
subject had been read, all of which, whilst showing interesting variations, 
agreed in the absence of the septal flap of the right cardiac valve. This cha- 
racter was shown to exist also in Echidna, and was therefore presumed to 
be a distinctive feature in the structure of the Monotremes. — A communi- 
cation was read from Mr. F. Moore, F.Z.S., containing the description of 
some new genera and species of Asiatic Lepidoptera Heterocera. — A com- 
munication was read from Mr. G. B. Sowerby, jun., in which he gave 
the descriptions of five new species of shells from various localities. —
