Ordinary Meeting, January 8th, 1867. 
Edward Schunck, Ph.D., F.R.S., &c., President, in the 
Chair, 
Mr. Binney, F.R.S., F.G.S., exhibited two remarkable fos- 
sils discovered by Mr. Joseph Tindall, of Thomas Street, 
Huddersfield, in the lower coal measures near that town. 
One was an insect, and, according to Mr. Tindall, belonged 
to Dr. Dawson’s genus Xylobius and probably to his species 
Sigillarice. It was found in an old deep mine at Cooper 
Bridge, and is the first instance of a specimen of that genus 
having been met with in England. The other bore some 
resemblance to the pupa state of a coleopterous insect, not 
much unlike the pupa of a nut weevil or some such insect. 
It was found in the Cinderfield Dyke Pit at Bradley, near 
Huddersfield. These specimens give us evidence of the 
former existence of insect life during the corboniferous epoch 
which a few years since we should scarcely have expected ; 
but after the discovery of a fossil spider in the German coal 
measures scarcely to be distinguished from a recent genus, we 
must expect great additions to be made to the carboniferous 
fauna, as doubtless the rich and luxuriant vegetation of 
that remote period would afford food and shelter for nume- 
rous insects.
