through which the vascular bundle passed, connecting the leaf with 

 the stem (the leaf-bundle having been torn away) ; for the actual 

 leaf-base, which is closely connected with the stem, does not 

 appear to have been preserved in the Australian specimens, since 

 the lateral points of the parichnos' have not yet been detected. 

 This latter structui'e it would be hopeless to look for, if we 

 assume that the known specimens represent a " Bergeria " 

 condition of the stem, in which the epidermis has been lost 

 before fossilisation. 



The elongate-elliptical depression indicating the passage of the 

 vascular bundle is, as a rule, situated close to the upper angle of 

 the rhombic area. On examining the type-specimen, I noticed 

 that where these pits are central, or nearly so, they seem to be 

 only partially preserved ; that is to say, the lower portion of the 

 vascular depression has been filled up and preserved as a cast, 

 which, by its obliquity and projection, brings it nearer 

 the centre. It would be interesting to discover whether this 

 evidence is borne out in other examples that may come under 

 observation. 



On the same pieces of shale there are several fragments of 

 what at first sight appear to be remains of Cordaites, but, 

 although this genus has been recorded fi'om the Drummond 

 Range, in this instance, it seems safer to regard these frag- 

 ments as decorticated branches of Lepidodendron, chiefly on 

 account of the parallel grooving of the fragments bearing 

 indication of intermittent thickening along the slender ridges. 



Fig. 1, on Plate XXVII., is taken from a specimen from Wynn 

 Creek, Queensland, presented to the National Museum by R. 

 Daintree, Esq.; it was selected for figuring on account of the 

 greater detail on its surface.
