Pecopteris ? hepaticseformis Kidston, n. sp. 

 PI. VII. fig. 7. 



Remarks. — -A figure of a fragment of the smallest pinnuled fossil fern I have yet 

 seen is given natural size on PI. VII. fig. 7. The portion preserved shows part of a 

 pinna about 11 mm. long and about 1"5 mm. wide at its base, from where it decreases 

 very gradually upwards. The specimen is converted into a very black carbonaceous 

 substance, and indicates that the pinnules must have been of considerable thickness. 

 The nervation is not distinctly seen. Two of the pinnules, magnified 10 times, are 

 shown at fig. 7a, but some of them appeared to be slightly more lobed than those 

 enlarged. I have met with no fossil at all similar to this curious H epaticse-Wke little 

 species, which, however, in the absence of more complete specimens, I have placed 

 provisionally amongst the Pecopterids. 



Horizon and Locality. — Ten-foot Ironstone Measures : Coseley (?). In the 

 collection of Sir Charles Holcroft.
