REPORT OF THE 
increase the interest with which it will be regarded by 
Naturalists.* 
Mr. Wood has enriched the Palaeontology of Yorkshire by 
the discovery in the Mountain Limestone near Richmond, of 
a beautiful Encrinite, referable, perhaps, to the genus Cyatho- 
crinus. It presents a very remarkable feature, which, it is 
believed, is quite unknown in the history of, at least, this parti¬ 
cular group of Crinoidal Animals. The column or stem sup¬ 
porting the Richmond Encrinite gradually contracts in diameter 
tow^ards the base, so that it w'ould appear, from one or two 
almost entire columns in the possession of Mr. Wood, to have 
terminated nearly in a point. Three slabs, rich in remains of 
this new fossil, have recently been sent by Mr. Wood for 
presentation at the Annual Meeting. 
Through the Rev. R. B. Cooke of 'Wheldrake, W. C. Max¬ 
well, Esq. has presented two Slabs of new red-sandstone, with 
footmarks upon the surface, found near Carlaverock, Dum- 
frieshire. And the materials for studying these singular 
vestiges of ancient nature have been augmented by Professor 
Phillips’s gift of a large mass covered with footprints of 
Labyrinthodon from the same series of strata in Cheshire. 
Lieut. Anthony Cooke, R.E., has presented a large lehthyolite 
from the Coal Measures at Gilmerton, referable to the genus 
Holoptychius, and displaying the natural outline of the mouth 
and parts of both jaws of this fish, the specimen in this respect 
being probably unique. 
The Society is indebted to the late Dr. Mantell, for an 
interesting series of Bones of Iguanodon from the Wealden of 
the Isle of Wight, a contribution which derives additional 
interest from having been received so short a time before the 
death of the amiable and distinguished donor. 
Some further contributions to the Tertiary Collection have 
been made by the British Natural-History Society ; among 
^ Of four large specimens of Plesiosauri liitherto discovered in the lias of the 
Yorkshire coast, one (P. grandipennis of Owen) is at the Cambridge University 
Museum. Another (P. brachyspondylus of Owen) is at the AYhitby Museum, 
a third is now at York; the foiu’th and most perfect of all, remains at Midgrave 
Castle.
