XIII. Remarks on the Figured Specimens. 



A few of the more interesting specimens from the ten new 

 borings in Kent are figured in Pis. XI— XIII, either on account of 

 their rarity, or because of the horizon at Avhich they there occur. 

 The great majority of the other species recorded are well-known 

 fossils, which have been frequently, figured in various memoirs.

This species is only known from the Middle Coal Measures, with 

 the exception of a single record from the Lower Coal Measures of 

 Scotland. The specimen figured in PL XII, fig. 1, shows three 

 stems or branches of different sizes, all exhibiting the characteristic 

 leaf -segments attached at the nodes.
