GLOSSOPTERIS PRIM@®VA (Feistmantel). 
Frond spathulate, costa thick, grooved veins, emerging at 
an angle of from 20 to 30 deg., parallel, dichotomous, anas- 
tomosing, forming a polygonal network, which is wider and 
shorter near the rhachis, narrower and longer near the margin.

GLossoPpTERIS CLARKEI (Feistmantel). 
Leaves oblong ovate, obtusely acuminate; costa distinct, 
grooved in the middle. Veins parallel, dichotomous, free for 
the greater part of the leaf, like a Teniopteris, anastomosing 
only at the margin, twice or thrice forming a rhombo-polygonal 
network.

GANGAMOPTERIS (M‘Coy). 
Frond simple or impari-pinnate ; middle pinne spathulate, 
symmetrical, semi-elliptically pointed above, gradually tapering 
towards the base; lateral pinne variable, very acute, tapering 
from base or obliquely ovate, to trigonal or flabelliform, broad 
above, gradually narrowed towards the oblique adherent base, 
which is never auriculate, but moderately wide and embracing 
no costa; veins coarsely reticulate, many arising from the base, 
branching as they diverge towards the margin and frequently 
anastomosing to form an irregular polygonal network. 
GANGAMOPTERIS SPATHULATA (M’(Coy). 
Spathulate, symmetrical, equal sided, semi-elliptically 
pointed above, tapering towards the base to a slender petiole ; 
length 43 inches, width about 1} to 2 inches. (This is the 
rarest of the three forms in the Bacchus Marsh sandstones, 
M‘Coy.)

GANGAMOPTERIS OBLIQUA (M‘Coy). 
Frond wide, inequilateral, oblique, sub-trigonal, widest near 
the broadly rounded distal end, gradually tapering towards the 
base, which is not petiolate, but obliquely truncated, with a
