specimens of LepidopJiloios fuliginosus, is very like that of 

 Xenophyto7t described above. Indeed, Fig. i of Plate XII. 

 of the present paper might have been taken from the 

 middle cortex of LepidopJiloios fuliginosiis. Taking these 

 circumstances into consideration, I have little hesitation 

 myself in connecting these two fossil plants together and 

 in considering Xenophyton as the " root " of LepidopJdoios 

 fuliginosus. 



Other points in the anatomy of these two forms, such 

 as the secretory tissue lying beneath the periderm, 

 strengthen this identification. 



II. A STIGMARIAN ROOTLET PROBABLY RELATED TO 

 LepidopJdoios fuliginosus. 



A stigmarian rootlet probably closely connected with 

 the above described XenopJiyton, and therefore most likely 

 with LepidopJdoios fuliginosus, is contained in the Hick 

 Collection of Coal Measure Plants in the Manchester 

 Museum. Its Cabinet number is 109. Unfortunately, I 

 can find no locality given for this specimen, but from the 

 appearance of the surrounding mass of debris it was 

 evidently enclosed in one of the "coal balls," from which 

 so many interesting specimens have been obtained. The 

 rootlet has a diameter of five to six millimetres, so that it 

 will be seen to be of a fairly large size. It is almost 

 spherical in section, showing little or no lateral com- 

 pression, a fact which is doubtless in some measure due to 

 the firmness of its tissues, which are all very perfectly 

 preserved {Plate XI 1 1., Fig. i). The outer cortex is not of 

 great thickness, being composed of only four or five layers 

 of cells, of which the outermost row consists of cells of 

 much smaller size than the inner cells. In no place is there 

 any appearance of rhizoid-like prolongations of the 

 epidermal cells, nor are any other projecting lateral
