In the specimens recently received Parka decipiens is re- 
presented by both stems and fruit. In the slates from 
Myreton are two carbonized stems 5 and 5.5 em. wide. 
Both are strongly rugose and folded back and forth as if in 
a highly pliable or partly decaying state when imbedded. 
The carbonaceous matter is much thicker and more gener- 
ally abundant than in the case of any of the other speci- 
mens examined by me. In the larger of the two, which 
measured 78 ¢.m. in length, there were observed to be five 
rounded pits with an average diameter of 8 mm., strongly 
suggestive of the possible position of roots. No positive 
evidence of branches could be obtained. 
In a specimen of sandstone from Rescobie, there was 
found an irregular mass, possibly the rhizome of P. 
decipiens, Showing numerous small, round pits and processes 
about 4 mm. in diameter, also presenting the aspect of root 
stumps, but from the imperfect state of preservation it was 
quite impossible to trace any connection between it and the 
well defined stems of other specimens. From Rescobie 
there were also obtained two good impressions of masses of 
sporangia. The remains are ferruginous and belong to the 
type of the species.

This varietal form is represented by stems which were 
not included in the material upon which the original 
description was based. They occur in the slates from 
Myreton, are slightly carbonized and measure from 15-20 
mm.in width. In one case there was an imperfectly de- 
fined branching. The sandstones from Rescobie also con- 
tain ferruginous impressions of stems of the same width— 
15 mm.—which are distinctly branching, and in one case
