(3) Note on a new species of Plesiosaurus from the 
Portland Limestone. By Mr H. Surety, F.G.S. 
Some time back a specimen of the fore limb of a Plesiosaur 
was obtained from the Portland limestone for the British 
Museum. Remains had also been found which had been re- 
ferred to Pliosaurus. The specimen of two vertebree which was 
exhibited was undoubtedly a Plesiosaur, but appeared to Mr 
Seeley to show certain approaches to the Pliosaurian type.
