tissue, though this is more prominent in B. eathiense. Transfusion trachee are 
abundant in the American type, though they do not appear to form such well-defined 
groups as those shown in fig. 4; it is noteworthy, however, that Hottick and Jerrrey * 
speak of the transfusion tracheze as forming a continuous band, as is the case in the 
leaf reproduced in fig. 2. 
The leaves of the Brachyphyllum eathiense possess certain features in common 
with those of Yezona vulgaris, a species described by Dr Sroprs and Dr Fusit from 
Upper Cretaceous strata of Japan, and regarded by them as the type of a new 
family for which they proposed the name Yezoniacez. It has, however, been shown 
by Jurrrey { that the Japanese species should be referred to the genus Brachyphyllum, 
and with this conclusion Dr Sroprs§ has expressed her agreement. 
Attention has already been called to the resemblance of the leaves of B. eathiense 
as regards the groups of transfusion cells to those of some recent species of Araucaria. 
There is no indication in the Brachyphyllum leaves of any of the large sclerous 
idioblasts which form so conspicuous a feature in those of recent Araucarias, and 
it is hardly likely that their absence is the result of partial preservation of the tissues. 
In the absence of any information as to the pitting of the metaxylem elements we 
cannot speak with confidence as to the degree of affinity with recent Araucariez, 
though in view of the agreement of the leaf-structure with that of Brachyphyllum 
macrocarpum, in which Araucarian pitting has been demonstrated, it is highly 
probable that B. eathiense is more closely related to Araucaria than to any other 
existing genus.

MILLER’s specimen consists of an axis bearing branches with spirally disposed linear 
leaves of the Taaites type, this designation being used in a wide sense as embracing 
leafy shoots with leaves like those of the Taxaceze, species of Podocaipus, and some 
other Conifers. In habit the branches agree closely with Stachyotaxus,|| a genus founded 
on the characters of the inflorescence. 
The main axis, 3°5 mm. in diameter, has a xylem cylinder of two annual rings 
enclosing a pith of rather large parenchymatous cells some of which, as seen in 
longitudinal section, are slightly elongated in a transverse direction, while others are 
three or four times as long as broad. The pith may be described as consisting of a 
more or less regular alternation of a few layers of horizontally extended and vertically 
elongated elements. ‘The bands of horizontally extended elements suggest comparison 
with the pith of Abzes magnifica,1| in which bands of flat sclerous cells form transverse
