 Fredville Series at 1387 feet. 



This species is quite abundant in the Waldershare Series. The 

 size of the leaves, however, is much greater than in the case of 

 any other specimens that I have previously seen. In a typical 

 specimen from the Eadstock Series of the Somerset Coalfield, the 

 length of the leaf is about 4 or 5 millimetres. In the examples 

 from Kent, the leaf is 8 to 10 millimetres long. Yet in other 

 respects these two plants appear to me to be identical. The shape 

 of the leaf is very similar, but the apex appears to be slightly 

 broader and more truncate. It may be that more than one species 

 of Calamite-stem bore leaves of this type, which when isolated 

 can hardly be distinguished one from the other ; but, at present, 

 I do not find any good grounds for regarding the specimens from 

 Kent as distinct from those of the Coal-Measures of other parts 

 of England.

Leaves and stems of Sphenophyllum are of common occurrence in 

 both cores, but the specimens are as a rale fragmentary. The 

 apices of the leaves are usually broken or badly preserved, hence 

 many of the specimens cannot be determined specifically. Such 

 fragments occur in the Waldershare core at 1761, 1830, 1835, 

 1836, 1838, 1839, 1842, 1843, 1863, 1871, and 1901 feet.
