2. DESCRIPTION OF THE PLANT-REMAINS. 
Equisetum, sps. 
Obs.—There are two compressed fragments of Hquwisetwm, 
probably distinct from one another. One is three and a half 
inches long by one inch wide, containing within the length two 
nodes, and portions of three internodes. The surface is delicately 
striate. 
The other example is three inches long and three-sixteenths of 
an inch wide, with five nodes, and portions of six internodes. On 
the flattened surface there are six longitudinal grooves continuous 
throughout. The specimens are too imperfect to render compari- 
sons with published species of any practical value. 
Teniopteris (Oleandridium ?) fluetuans, sp. nov. Pl. v., figs. 1-3. 
Sp. Char.—Frond simple (so far as known), elongately lanceo- 
Jate, thick, coriaceous, crumpled, lateral margins sinuous. Mid- 
rib thick, moderately wide, and possibly longitudinally striate ; 
secondary veins fine, straight, two in the space of one and a half 
mm., passing from the mid-rib at a right angle, sparsely furcate, 
and when so generally on immediately leaving the mid-rib, very 
rarely in the middle of the wing. 
Obs.— When in the perfect state this must have been a remark- 
ably fine leaf. It is now eight inches long, and incomplete at 
either end. The lower portion exhibits only the mid-rib and 
fragments of one of the wings attached. The breadth of the full 
frond where preserved is one and a quarter inches. The general 
facies of the frond seems to point to Oleandridium rather than 
Teniopteris proper, but we know nothing of the fructification of 
the plant. If an Oleandridium it is near O. vittatum, Brong.,* 
although Brongniart’s figures do not show any fluctuation of the 
margins, nor crumpling of the surface. On the other hand, 
Fiestmantel’s illustrationt of the Indian variety of this species 
decidedly manifests a sinuosity to each margin, and the fronds 
are to some extent crumpled also. 
The question arises, in how far is this crumpling a natural or 
superinduced character? If the former, it will stand as a good 
specific character, and is certainly the first Teniopterid I have 
seen from Australian rocks with this peculiarity.
