confluent linear terminal pinnule ; all lobes oblique, rounded, 
with margins rough or finely venulate; primary vein of each 
lobe emerging acutely from rhachis, from which radiate 
dichotomously numerous small venules which reach the 
margia; an occasional independent venule arises from 
rhachis towards sinus of each lobe. 
Pinne or frond (?), imperfect 2% inches long. Breadth 
across middle of terminal pinnule, 5 millimetres. Breadth 
across base, 14 millimetres. 
From greyish shale below 4 feet coal seam at Longford 
This is probably a very variable species, as it corresponds 
in some respects with a protean form occurring in the shales 
associated with a similar coal seam at Spring Bay and at 
York Plains. There are certain characters which link this 
form with the genus Odontopteris, but until more perfect 
specimens are obtained, it is referred by me provisionally to 
the genus Pecopteris. The veins are invariably strong and 
prominent, very unlike the fine neuration of Thinnfeldia 
Odontopteroides (Morris). 
ALETHOPTERIS (PecorrEeRis), AUSTRALIS. Morris. 
Frond bipinnate ; pinne oblique, alternate, rather distant ; 
pinnulee thin faleate and rather obtuse, oblique and somewhat 
incurved, more orless adnate to the rhachis, and sometimes 
decurrent, dilate at the base, or auriculate; midrib slightly 
flexuous, evanescing towards the apex; veis oblique, 
bifurcate, or dichotomous.

THNIOPTERIDE. 
Fronds stipitate, simple, oblong, lanceolate, and broadly 
elongate, entire or pinnate ; pinne linear, lingulate, more or 
less acuminate, shortly pedicellate or sessile. Rhachis and 
costa conspicuous ; velns emerging at an acute angle, but 
immediately becoming horizontal or oblique, simple and 
dichotomous. Sori transversely oblong, sub-marginal or 
rcunded, and scattered over all the lower part of the surface, 
or in series along the venules.
