occur that “it was possible for an active and greedy collector 
to have boxed 1000.” On no occasion since has it been so 
abundant. In 1880 only two were obtained; in 1881—4 none 
had been seen, and in 1885 only one. His own observations 
corroborated this. It had been observed over an area of more 
than ten miles. His friend Mr Merry, who first found the 
species in about 1858, had discovered its eggs, but all efforts 
to rear the larve had failed, doubtless owing to the fact of the 
larvee hybernating when very small. Mr Merri had informed 
him that it had disappeared in the cold wet year of 1860, and 
was not again seen until about 1866; from that year to 1870 it 
had increased in abundance. The years 1876 and 1877 were 
also good years for it. The butterfly had also disappeared 
from its Devonshire locality. The distribution of the butterfly 
in Burope was everywhere local, and it rarely appeared in 
abundance. It was found in several districts of the Alps, and 
in other elevated spots. 
Tn the discussion that followed Mr Merrin gave details of 
the past history of the insect in the Cotteswolds. It had been 
much sought after by collectors from a distance, and by dealers, 
and this, combined with the “ unseasonable” seasons from 
which we had suffered for so many years, was probably sufficient 
to account for the disappearance of the insect. He, however, 
had hopes that with the return of sunnier seasons it might 
re-appear. 
Professor Harker showed an excellent coloured drawing of 
the species, a copy of which will appear in the published 
Transactions of the Club. 
A paper followed by Mr 8. 8. Buckman, F.G.S., on “ Some 
new species of Brachiopods from the Inferior Oolite of the 
Cotteswolds.” The railway from Cheltenham to Bourton-on- 
the-Water has cut deeply into the high lands of the Cotteswolds, 
affording to the Geologist some extremely fine sections. Chief 
among these, in a paleontological point of view, is the section 
at the Notgrove Station. It exposes the Oolite Marl, and, by 
sudden faulting at the east end, the upper beds of the Inferior 
Oolite, and even the Fuller’s Harth beds are brought down at a
