distinguished by its large fins and produced snout. In general 

 appearance it has much resemblance to P. angustm, Ag., to which 

 I provisionally refer it. 



The specimen is in the collection of Mr. W. M. "Wake, and was 

 found in the Old Quarry, Fulwell. 



PLANTS. 



Ulmannia selaginoides, King. 



Several specimens have occurred, usually more or less frag- 

 mentary, of a vegetable that evidently belongs to the above spe- 

 cies. The specimens are generally impressions, with traces of 

 carbonaceous matter, the nervation of the leaves being occasion- 

 ally shown on the impressed surface. The finest example is 1 1 

 inches long, with a branch of 3^ inches, and is in the Museum 

 of Practical Geology, London. 



Ulmannia, sp ? 



I have also examples of another plant, belonging apparently to 

 the same genus as the preceding, but they are not sufficiently 

 perfect to allow me to describe from them. 



Calamjtes abenacetts ? JBrongn. 



Among the vegetable remains are two specimens of a Calamite, 

 which I doubtfully refer to this species. The specimen in my 

 possession is 4-J- inches in length and nearly an inch in width. 

 It shows two joints, 1£ inch distant from each other; and the 

 impressed surface is rather finely striated longitudinally. 



Besides the preceding species, a single specimen has occurred of 

 a large reed-like plant which I have not been able to identify. 

 It is 21 inches long and 1 inch broad, rather coarsely striate longi- 

 tudinally, and without any indications of constrictions or joints. 

 The specimen is in the collection of Mr. Arthur Dixon. 



I have to acknowledge the assistance of Mr. Howse in deter- 

 mining the plants. 



So far as may be judged from the fossils I have described, the 

 physical conditions that prevailed during the deposition of tb e
