ORDINARY WINTER MEETINGS, 1916 
Tuesday, February 15th, 1916. 
W. St. Clair Baddeley, President, in the Chair. 
The Minutes of the Meeting held November 23rd, 1915, were read, con- 
firmed and signed. 
Mr F. J. Cullis exhibited a fine specimen of a Giant Puff Ball [Lycoperdon 
bovista, Linne), found, beneath the floor of a house in St. Aldate Street, 
Gloucester, a very unusual situation ; and Mr J. W. Skinner reports on 
The small objects and the human skulls found in the Hal-Saflieni prehistoric 
Hypogeum at Casal Paula, Malta.” Mr Charles Upton exhibited a specimen 
of palaeozoic glacial drift from Bigganjargga in the North of Lapland. The 
age was a little uncertain, but probably the rock was of the Silurian period. 
The glacial drift rested upon striated quartz rock, and was capped by similar 
rock. 
The following communication was made : — 
An Account of the Silurian Inlier of Usk, where there are 
exposed Beds of Ludlow and Wenlock Age, by C. I. Gardiner, 
M.A., F.G.S., WITH Paleontological Appendix, by F. R. 
CowpER Reed, M.A., F.G.S.* 
The paper was illustrated by sectional maps, and an interesting collection 
of fossils from the beds described, including five new species and two new 
varieties. 
The President expressed the interest created in the subject by the clear- 
ness with which the lecturer had presented it, and the Rev. H. H. Winwood 
congratulated him on the work accomplished and the records made of new 
species and varieties. Mr Charles Upton and Mr F. J. Cullis also joined in 
the discussion. 
Mr Gardiner then showed a series of lantern slides illustrating glacia 
action in Great Britain and elsewhere, and made some observations on the 
glacial periods and the antiquity of man.

ABSTRACT 
The distinguishing features of the Winter Moth as compared with the 
Codling Moth are that the former is a Geometer, flies in winter, has a semi- 
wingless female, which lays its ova in small groups, its larva feeds on leaves, 
and has only two pairs of prolegs ; while the Codling Moth is a Tortrix, flies 
in summer, has a winged female, which lays its ova singly, its larva burrows 
into fruit and has five pairs of prolegs.
