sspicuous above, sub-terete underneath ; veins generally con- 
spicuous, slender, numerous, and close, dichotomous a little 
above the base; venules simple or dichotomous, parallel, with 
-an occasional intermixture of simple nerves. 
TmNIoPTERIS Tasmanica. Nov. Sp. 
Frond simple, broadly strap-shaped, not obovate; midrib 
‘moderately strong; veins well defined, exceedingly close and 
numerous, parallel, emerging from midrib at an acute angle, 
and immediately bending and reaching margin at a slight 
angle upwards. About one nerve in ten simply furcate near 
middle of wing; about 24 nerves in the space of half-an- 
inch. Length unknown. Breadth, about 46 millimetres, 
Common in the shales at foot of Spring Hill. This form 
approaches Macroteniopteris Wianamatta (Feistm.) of the 
Hawkesbury sandstone, but seems to differ from the latter by 
its closer neuration and its broadly strap-shaped form. Italso 
approaches 7’. densinervis (F'eistm.), from Kukurbit, India, but 
it would appear that the latter differs in having the nerves 
more delicate if not more dense, and in being more frequently 
furcate. 
TNIOPTERIS Morristana. Nov. Sp. 
Frond simple, narrowly strap-shaped; costa fine ; veins 
numerous, parallel, onein six simply furcate, emerging and 
radiating outwards at a moderately acute angle to margin. 
Length, unknown; breadth about 16 millimetres; nerves fully 
1 millimetre apart. 
Occurs ina greyish white shale below 4 feet coal seam 
belonging to Mr. Mason near Longford. Associated with 
Zeugophyllites elongatus (Mor.), and Alethopteris Australis 
(Mor.). 
T. Morrisiana is a very distinct form from T. Daintreet 
(M‘Coy). It approaches Oleandridium vittatum (Bret.) far 
more closely. It differs from the latter in the less frequent 
furcation of the nerves and in the delicacy of its midrib, 
O. vittatum being very strong comparatively. It is more 
closely allied to the example figured as T. Daintreei, by 
Mr. Carruthers (Quart. Jour. Geol. Soc. London, 1872, 
Pl. XXVII. fig. 1), but, which I consider, with Prof. M‘Coy 
(p. 16, Decade. Prod. of Pal. of Victoria, Pl. XIV., fig. 1), to be 
a very distinct species. See 7. Carruthersii, Tenison-Woods, 
Proc. Lin. Soc., 1883, Vol. VIII, p. 117. 
TNIopTeRIs DaintREEI (M‘Coy). 
Frond very long, linear, parallel sided; substance 
thick, edges straight, costa very strong; veins extending 
at right angles from the midrib to the lateral margins, 
a few straight and simple, the greater number once 
forked at a variable distance between the midrib and
