JURASSIC PLANTS FROM CROMARTY AND SUTHERLAND, SCOTLAND. 879 
to be the position of the seed is shown at s on the adaxial side of the ligule. Sporophyll 
B, fig. 19 (enlarged in fig. 17), is cut across in an obliquely transverse direction ; the 
large space is seen to the left, and above it are smaller spaces with part of the ligule at 
i. The section reproduced in fig. 18 (C, fig. 19) shows the large central space with 
vascular bundles above at v, and several smaller spaces in the broadly arched superficial 
region which is regarded as the ligule (cf. c and b, text-fig. 4, C). Both this scale and 
that shown in text-fig. 4, A (scale V.), agree very closely, in the occurrence of large resin- 
canals near the upper surface, with the scales of Arawcaria Cooku. Cone-scale EH, fig. 
19 (part of which is diagrammatically represented in text-fig. 4, C), is cut obliquely 
and approximately parallel to the upper face; there is an oval projection enclosing a 
space (a, text-fig. 4, C) in the middle of the broad end, and to one side of this is attached 
a strip of tissue, b, containing a smaller space; the detached piece c (text-fig, 4, C) no 
doubt also belongs to the median projection. The median projection and the lateral 
pieces (b and c) probably belong to the ligule and correspond with the upper part of 
the cone-scale shown in fig. 18, which is characterised by a row of spaces. 
The cone-scales at the lower end of the axis (fig. 19), which are cut close to their 
proximal ends, are of the same type as those represented in figs. 9 and 12. In the 
cavity of the cone-scale D, fig. 19 (shown on a larger scale in fig. 20), there is a delicate 
structure, a, with incurved ends and below it a smaller V-shaped body, b; these two 
bodies may be sections of one structure bent on itself like a folded embryo. A single 
V-shaped body identical with b in fig. 20 is seen in the large space at a@ in fig. 17. 
We are unable to interpret these peculiar stractures ; if the large cavities in the cone- 
scales were homologous with the seed-containing portion of an Araucarian sporophyll, 
it might be reasonable to regard the enclosed structures as portions of the seeds, 
possibly of the embryos; but if our interpretation of the cavities as spaces in the cone- 
scales below the vascular strands, which are not connected with the seeds, is correct, 
the bodies shown in figs. 17 and 20 are in all probability the remains of some foreign 
organism. 
Affimties of Conites Juddi. 
The large form of Contes Juddi (forma 8, text-fig. 2, C) is similar in habit to some 
strobili from the Bunter Sandstone of the Vosges, referred by ScotmperR and Movucxor 
to Voltza heterophylla,* and the cone-scales may be compared also with those of 
Poronis's genus Voltzopsis,t but there is no evidence of actual affinity between the 
Scotch cones and those of Triassic and Permian age which present a superficial resem- 
blance to them. A closer similarity, especially as regards the form of the cone-scales, 
is afforded by a Lower Cretaceous species, Mricia nobilis, described by VELENovsKY 
from Bohemia; it is by no means unlikely that in this case there may be a relationship
