176 Dr Hibbert on the Limestone of Burdiehouse 



Hut ton). The circumstances under which these vegetable relics 

 are found, appear to be the same which had been previously re- 

 marked in another and very distant locality. At Burdiehouse, 

 the Lepidophyllum intermedium is found lying along with Cype- 

 rites bicarinata. But whether this coincidence ought to stimulate 

 to any fresh inquiry regarding the true character of each, I would 

 not offer any opinion whatever, as it is but too possible that the 

 association might have been purely accidental. At least, " it is 

 curious," as Professor Lindley has remarked to me, " that these 

 two fossils, which have no sort of relation to each other, should 

 have occurred in association with each other, both in the Lee- 

 botwood coal-pit and at Burdiehouse." (Compare plate 43 of 

 L. fy H.'s Fossil Flora with Fig. 5 of Plate VI, given in this 

 memoir!) 



Regarding the cylindrical and imbricated cones supposed to 

 be naturally connected with the Lepidodendron, (a notion to 

 which much countenance is given by the character of the remains 

 discovered at Burdiehouse), two kinds may be identified, viz. the 

 Lepidostrobus variabilis, (Lindley and Hutton), PL 10 and 11), 

 and the L. ornatus (ibid. PI. 26). 



No cardiocarpon which can be safely attributed to Lycopo- 

 diaceas has yet, to my knowledge, turned up. I have only ob- 

 served the Cardiocarpon acutum of Messrs Lindley and Hut- 

 ton (See Foss. Flora, pi. 76), which is supposed by them to 

 belong to other plants. 



These very general remarks must, on the present occasion, be 

 deemed sufficient. 



It is thus shewn, that the smaller ferns, referable to Sphenop- 

 teris, together with the disjointed organs of Lycopodiaceae, con- 

 stitute the great majority of vegetable remains entombed in the 

 limestone of Burdiehouse. Along with these are found, but 

 comparatively in less number or quantity, relics of the Stigma- 

 ria ficoides, and of the less common species belonging to Sigil- 

 laria, Equisetum, Calamites, and Cyclopteris. But as attention is
