CARPOLITHUS MARGINATUS. 



BORDERED CARPOLITJ1E. 



Generic Character. 

 The fruits, or seeds, of plants, in a fossil state. 



Specific Character. 

 CARPOLITHUS marginatus. An ovate nut, rather bulged towards the top; 

 edges broad, flattened ; the tip blunt, slightly indented ; shell deeply furrowed longi- 

 tudinally. 



Synonyms. 

 This fossil fruit has not been found described or figured in any author. 



Description and Locality. 

 Nut ovate, rather bulged towards the top, compressed, flattened on the sides 

 and at the base, tip indented, furrowed longitudinally ; furrows rather deep. 

 Epidermis very thick, bituminous. 

 Found in the fine sandstone of Lea-brook quarry. 



Observations. 



This nut, whose figure is shown at B and C in the plate, is accompanied with a 

 variety of other vegetable remains; such as fragments of sternbergia, of an unknown 

 poacite, and a carpolithus, exhibited at A, which evidently appears to have been the 

 strobile of some tree. 



There are also imbedded in the same mass, the remains of several other plants, 

 which are in such an imperfect state that no characters can be given of them : but 

 the view of this mass, taken altogether, serves to show the variety of plants that 

 existed on one and the same surface. 



The carpolithus figured by Count Sternberg, in his 7th plate, figure 12, may 

 perhaps be of the same species; but the base has an appendage which is not seen 

 in the species figured.
