was a well-known species, common on chalky soils, and he had seen it in
Kent, Sussex, Surrey, Wiltshire, and on the limestone in Derbyshire, &c.
It evidently prefers, and most likely requires, chalk or lime for its opera-
tions. He suggested that search should be made at Purfleet or Grays,
on the chalk, for the mollusc.
The President said it was clear from Mr. Dalton's and Mr. Christy's
observations that Cyclostoma had once lived in Essex, possibly finding
suitable conditions in the chalky boulder-clay; and he suggested the
possibility that the disappearance of the species was due to the removal
of the chalky clay by superficial denudation and other causes.
Mr. H. J. Barnes exhibited some shells of a species of Ostraea found in
large quantities in digging a new sewer at Leyton at a distance of about
twenty feet from the surface.
Mr. H. Corder exhibited, and read some notes on, three Neolithic
Implements from the neighbourhood of Chelmsford [Trans, ii. 29.] He
also exhibited and explained some ancient Bronze Implements ("Socketed
Celts"), found two years ago in a field near Little Baddow, Essex [Trans.
ii. 31], and some bones of Pleistocene Mammalia from the brick-earth,
Chelmsford.
Mr. James English read a paper entitled "The First Night's 'Sugaring'
in England : a reminiscence of Epping Forest in 1843" [Trans, ii. 32.]
Mr. Meldola said he was sure Lepidopterists would read with pleasure
Mr. English's chatty account of the earliest application of a process to
which they owe a revolution in the extent and beauty of then- collections.
One interesting fact appeared to be clearly established by the use of the
method of "sugaring," and that was the possession of an organ of
smell by Lepidoptera and other insects. He suggested that it would be
an important experiment to remove the antenna; of moths, and see if
they found their way to "sugar" when thus mutilated. In the course of
conversation Mr. English expressed his belief that moths would not come
freely to sugar when the trees were infected with honey-dew, and that the
circumstance explains one at least of the causes of the uncertainty of
sugaring as a mode of collecting.
A unanimous vote of thanks was passed to the authors for their
papers.
At the Conversazione Mr. J. S. Morten exhibited, under the microscope,
some specimens of parasites belonging to the genera Argas, Trichodectes,
and Haematopinus ; Mr. J. D. Cooper two Flint Spear-heads and a Knife
from the Ancient Indian Burial Mounds near Belize, Central America ;
and Mr. W. Cole a series of Noctua for the purpose of illustrating
Mr. English's paper.
