new genus, of a very remarkable form, serving to connect the already 
established genera of Lwtra and Anhydra, which he called Pteronura 
Sambachii. 
Mr. J. E. Gray exhibited some new land shells observed by him in 
the Collection of the Royal Institution of Liverpool. One was stated 
to be a new genus, intermediate between Helix and Anostoma. ‘The 
others were new species, which he proposed to designate by the names 
of Achatina turrita, Carocolla filomarginata (from India), and Palu- 
dina Yatesii, this last being the largest and one of the most beautiful of 
the genus. Mr. Gray also exhibited a specimen of Unio Roisii, Mitch., 
which had been recently discovered by Mr. Wm. Gilbertson, near 
Boughton, in Craven. ' 
Specimens of wood, from the New Pier of Southampton, penetrated 
by Limnoria terebrans, were exhibited by Mr. W. S. MacLeay, F.R.S. 
The pier was constructed only four years ago, and was reported to be 
already in a state of decay. 
A specimen of Goliathus giganteus, and the jaws of a large shark, 
(3 feet in length), caught by Captain Nash, were exhibited by Mr. F. 
Taylor. 
Some rare Coleopterous insects, from the collection of Mr. Melli, 
of Liverpool, were described by the Rev. F. W. Hope and Mr. MacLeay.

as existing in a recent state.
