tial charring that the impress of the wings of the two seeds may still 
be made out. The superficial features of isolated cone scales of 
Pinus, in view of the great similarity of cone scales of not very 
closely related species among living pines, can scarcely have more 
than a generic significance, so we have refrained from giving any 
specific name to the type of scale depicted in our figures. It is prob- 
able, in view of the presence of several diverse types of short shoots 
in the Kreischerville deposits, that a somewhat similar type of cone 
scale may have characterized several different species of these pines. 
Figure 6, Pl. 23, shows the general features of internal structure 
present in a transverse section of such a cone scale, X 40. There 
is a single series of bundles present, with the xylem lowermost, as 
is the case in living pines. One of the bundles appears in the center 
of the figure. The fibrovascular strand further resembles those 
found in the ovuliferous scales of living pines, in the very sparing 
development of transfusion tissue. In this respect, both in living. 
and in Cretaceous pines, there is a marked contrast between the repro- 
ductive and vegetative leaves, since in both extant and extinct pines 
transfusion tissue is very strikingly present in the foliage, although 
absent or confined to the flanks of the bundles in the case of the 
sporophylls.

Quite common among the coarser plant remains found in the 
Drummond pit are pieces of coniferous bark, characterized by the 
scaly structure which is found in the case of rhytidomes; and as we 
have found similar bark in actual connection with Cretaceous pity- 
oxyla elsewhere we are disposed to consider it as probably belonging 
to some species of Pinus. 
This material is unquestionably identical with that to which Dr. 
Lester F. Ward gave the generic name of Feistmantelia, the prob- 
able nature and affinities of which he discusses at some length in a
