Tue particular interest of the new species of Bennettites about to be described 
is mainly three-fold :—(1) It is the smallest and youngest trunk yet known ; 
(2) it is the first European specimen to include well pelted young foliage ; 
(3) it is well preserved, thus elucidating some anatomical details of leaf- 
structure in the genus hitherto not Bieapietely known from American 
specimens of. other species. It is also suggestive of the conclusion that 
Bennettites produced detachable trunks adventitiously arising as buds com- 
parable with those found on the living Cycas circinalis. 
General Description. 
The specimen had leng lain in the British Museum (Natural History) in a 
number of unconnected pieces, and had been transferred without history 
from the Botanical Department in 1898 to the Geological Department, where 
it now is. The specimen, cut into four separate pieces and two slides long 
since, had passed through many hands and been given six different and 
unassociated catalogue numbers, viz., V. 4502, V. 4767, V. 4782, V. 5445, 
V. 5650, and V. 8423. Some of these had been associated by Mr. W. N. 
Edwards, of the Geologieal Department, British Museum. 
The parts when all ought together fitted so well that there is no doubt 
of their forming a single specimen. There is no record of the horizon or the 
locality of its source. : 
The tiny trunk was oval in horizontal outline, and rather like a somewhat 
pointed pear in vertical elevation. It much resembled outwardly, both in 
size and appearance, a large Williamsonia fruit, being only about 8:5 em. 
in height, and with a largest diameter of 7x5 em. “Text-fig. 1 gives in 
outline the appearance of the specimen in natural size. de ago it had | 
been cut across about the middle, cut (1) in the figure, and the upper piece 
had then been cut once vertically to this and along the’ shorter diameter, 
cut (2), and then one of these resulting portions cut again in half at right 
angles to this eat and along the larger diameter, cut (3). These cuts gave, 
| the large basal piece A, the half of the upper half, B, and the quarters of the 
upper half C and D. From these in the early days two thick lonvitudinal 
sections had been: made from the faces of cuts (2) and (3). 
When I began work on the specimen Dr. Smith Woodward, F.R.S. „kindly 
allowed me to have a complete series of sections from the lower part A,
