8 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 

 towards the base, so that it would 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 Ichthyolite 

 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 aniiable 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 hitherto 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 Whitby Museum; 

 a third is now at York ; the fourth and most perfect of all, remains at Mulgrave 

 Ca&Uc.
