174 DR ROBERT KIDSTON ON THE 



Staffordshire Coal Field, many of them appear to be very rare, though perhaps they 

 may be much more common than is at present suspected, for from many localities 

 I have few or no records, and from some of the coal seams, especially in the northern 

 area of the coal field, there are no records at all. 



The publication of this paper may call the attention of some to the deficiency of 

 records from many of the coal seams, and I would ask such to lose no opportunity 

 for collecting specimens, so that we may gain a more accurate conception of the 

 vertical and horizontal distribution of the fossil plants of this coal field. 



The following table contains a list of al] the species found in the South Staffordshire 

 Coal Field, and gives their vertical distribution. The list is very typical of the 

 Westphalian Series.
