point being that the new cone has compound branched sporophylls, 
each of which bears a number of sporangia. It became evident that 
this cone must be placed in a new genus, and the conclusion arrived 
at from the study of the peduncle was thus confirmed. 
Mr. Kidston most generously handed over his sections to me for 
examination and description, and also obtained for me from the 
owner the remains of the original block, from which I have had 
a number of additional sections prepared. 
Only a single specimen of the cone is at present known. Before 
cutting sections, the piece, which includes the base but not the apex 
of the strobilus, was about two inches long. It was found at Pettycur, 
near Burntisland, in 1883, by Mr. James Bennie, of Edinburgh. The 
specimen is calcified, and its preservation is remarkably perfect, so 
that the whole structure is well shown, though the complexity of its 
organization renders the interpretation in some respects difficult. 
The cone in its present somewhat flattened condition measures 
about 5 cm. by 2-3 cm. in diameter. The diameter in its natural 
state would have been at least 3-5 cm. That of the axis is about 
7 mm., exactly the same as that of Williamson's peduncle. Thus the 
extreme length of the sporophylls, which have on the whole an 
approximately horizontal course, is about 1-4 cm. 
The sporophylls are arranged in somewhat crowded verticils, 
fourteen of which were counted in a length of an inch, 2-5 cm. 
There are twelve leaves in each whorl, and the members of successive 
whorls are accurately superposed, a fact which is shown with the 
greatest clearness in tangential sections of the cone. This is evidently 
a point of great significance in considering the affinities of the fossil. 
The sporophylls themselves have a remarkably complex form. At 
its insertion on the axis each sporophyll consists of a short basal 
portion or phyllopodium ; the bases of the sporophylls belonging to 
the same verticil are coherent. The sporophyll branches immediately 
above its base, dividing into a superior and an inferior lobe, which lie 
directly one above the other in the same radial plane. Almost at the 
same point each of the lobes subdivides in a palmate manner into 
three segments, which assume a horizontal course, whereas the 
common phyllopodium has an upward inclination. It is probable 
that sometimes, especially at the base of the cone, there may be two 
instead of three segments to each lobe. As a rule, however, each 
sporophyll consists of six segments, of which three belong to the
