276 PROCEEDINGS OF THE CONCHOLOGICAL SOCIETY, 
to go forward by Sample Post on the chance of their not being 
stopped by the Post Office of the countries of destination. At that 
time opinion and practice in this respect varied in different parts of 
the Postal Union; but since then the Postal Union decided not to 
make a rule admitting natural history specimens to the reduced rate 
of postage for samples, so that there was no longer any doubt as to 
the irregularity of forwarding the specimens in question at the sample 
rate; and the Postmaster-General had therefore no alternative but to 
withdraw the instructions formerly given to the officers of the depart- 
ment to allow them to pass. 
IT am, Sir, 
Your obedient Servant, 
W. ROCHE 
The Rev. J. W. FLORSLEY. (For the Secretary). 
Exhibits : 
By Mr. R. D. Darbishire : Some shells brought up on the anchor cable 
during a recent voyage on the west coast of South America— 77ophon xantho- 
stoma, Nassa dentifera, Purpura chocolata, Turritella cingulata, Fissurella 
picta, and a particularly fine specimen of Cyfr@a nigropunctata. 
By Mr. Wm. Moss: Pufa Eyries? from Trinidad. 
By Mr. J. T. Marshall: Gwyn7a capsula in situ from Jersey. 
By Mr. Thos. Scott: A series of freshwater shells from Shetland, com- 
prising Limnea peregra and Planorbis glaber, from Flossie Loch, Gulber- 
wick ; Planorbis contortus and P. nautileus from Asta Loch, Scalloway ; 
Limnea peregra and L. truncatula from Tingwall Loch, Scalloway. 
Also Limnea peregra, L. palustris, Physa fontinalis, Valvata piscinalis, 
Planorbis contortus, P. albus, P. nautileus, P. nitidus, Pisidiwum milium, 
and P. mztidum, from Rescobie Loch, Forfarshire. 
A large number of examples, comprising some fifty species of Camena, 
Thersites, Hadra, and allied sub-genera, were exhibited by Rev. J. W. 
Horsley, Messrs. R. D. Darbishire, R. Cairns, W. Moss, T. Rogers, J. R. _ 
Hardy, R. Standen, and the Manchester Museum, and an interesting dis- 
cussion followed. It appeared that systematic exhibitions of particular 
groups would be particularly interesting and instructive to the members, 
and it was therefore decided to exhibit examples of Glamdina and its allies 
at the next meeting; and members were requested to bring or send any 
species they might have for comparison.
