recorded by Williamson, and by Salter. The latter are 

 not at the Jermyn Street Museum, as I have ascertained 

 by several visits ; although some of Salter's specimens, 

 from the Middle Coal Measures of Lancashire, are 

 preserved there. 



There are also several specimens in the Manchester 

 Museum, Owens College, which, by the kindness of the 

 Director (Dr. Hoyle), I have been able to examine and 

 describe here. 



Summary of Previous Records. 



Before describing the specimens which I have had an 

 opportunity of examining, it may be well to give a sketch 

 of the previous records of fossil plants from this coalfield. 

 As far as possible the nomenclature has been revised in 

 each case ; the more recent names being placed on the 

 right hand side of the original record. Where no emenda- 

 tion is given, the original name still holds good. The 

 reasons for these changes in nomenclature will be found 

 stated in the description of specimens, which follows. 



The earliest account of plants from the Manchester 

 Coalfield, with which I am acquainted, is that of the late 

 Professor W. C. Williamson, for many years Professor 

 of Natural History at Owens College, Manchester, whose 

 researches on the structure of carboniferous plants 

 rank as one of the most valuable contributions to Palaeo- 

 botany during the past century. In 1836, Williamson^ 

 recorded the following species from the red shales, 60 feet 

 above the Main or Three Yards Limestone, at Ardwick. 



Calainites decor atus Brong. = C. Suckoivii Brong. 



Calamites nodosus = C. ramosus Art. 



Lepidodendron Siernbergii = L. lycopodioides Sternb. 



Neuropteris cordata = N. ScheiicJizeri Hoffm. 



Cyclopteris sp. = Neuropteris sp. 

 Stigmaria ficoides.
