126 ON THE FOSSIL FLORA OF THE COAL DEPOSITS OF AUSTRALIA, 



There is no Indian or Australian form which resembles this in 

 the peculiar character of the midrib. From Greta, K.S. Wales, 

 under the marine paleozoic beds. 



Glossopteris primozva. Feist. (1. c, p. 79, pi. 5, fig. 3, 3a). — Frond 

 spathulate, costa thick, grooved veins, emerging at an angle of 

 from 20 to 30 deg., parallel, dichotomous, anastomosing, forming a 

 polygonal network, which is wider and shorter near the rachis, 

 narrower and longer near the margin. 



Locality— Greta, N.S.W., from the lower coal. It is also known 

 from Damuda in India. 



Glossopteris clarkei. Feist. (1. c, 79, pi. 5, fig. 4, 4a). — Leaves 

 oblong ovate, obtusely acuminate, costa distinct, grooved in the 

 middle. Veins parallel, dichotomous, free for the greater part of 

 the leaf, like a Tceniopteris anastomosing only at the margin, twice 

 or thrice forming a rhombo-polygonal network. Locality — Under 

 the marine beds, Kix Creek, N.S. Wales. 



Glossopteris browniana, var. prcecursor. — Leaves small, long, spa- 

 thulate, costa distinct, fading away towards the apex ; veins 

 emerging at an acute angle, curved, forked, anastomosing, forming 

 a sub-equal elongate, polygonal network. (Feistm., 1. c, p. 79, 

 pi. 5, fig. 4-7.) Under the first marine beds of Stoney Creek, 

 N.S. Wales. 



Gangamopteris, M'Coy. 



Frond simple or impari-pinnate, middle pinnae spathulate, 

 symmetrical, semi-elliptically pointed above, gradually tapering 

 towards the base ; lateral pinnae variable, very acute, tapering 

 from base or obliquely ovate, to trigonal or nabelliform, 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. 



This genus was formed by Professor M'Coy in the Decades of 

 Paleont. of Vict. (p. 11, pi. 12 and 13), the name being derived 

 from yayyaiiov, a small round net, and me pis a fern. A species
