Belemnopteris Wood-Masoniaista, n. sp., PL XX, Figs. 1 — 2. 



Fronde simplici, late sagittaefolia, apice obtusa, margine integerrima, 

 tota ad 105 cm longa, lobis obtuse acuminatis longioribus ("5*3 cm long is) ; 

 nervis primariis tribics ; uno crassiore infolii superficiem excurrente, duobus 

 aliis tenuioribics, in lobos currentibus, omnibus tribus apicem versus 

 attenuantibus ; nervis secundariis sub angulo subacuto eggredientibus, anas- 

 tomosantibus, retia plerumqxie hexagonalia, sed etiam polygonalia, forman- 

 tibus. Fructificatione ignota. 



Of the relations of this fern I have already spoken when discussing 

 the genus ; they are only in the living flora, nothing like it being known 

 amongst fossils. 



The frond is simple, is shaped like a broad arrow, at the apex obtuse ; 

 the margin entire, slightly arcuate, the total length 10'5 cm ; the basal 

 lobes obtusely aciiminate, pretty long (5 - 3 cm.). The chief characters lie 

 in the veins : there are three chief veins, one passing into the surface of 

 the leaf, the two others, a little thinner, into the two basal lobes. 



The secondary veins pass out at a subacute angle so as to form a net- 

 venation with hexagonal or polygonal meshes. 



This is one of the finest specimens in Mr. Wood-Mason's collection. 

 G-enus Gangamopteris, McCoy, 1875. 



I have already had occasion to mention this genus in my first note on 

 the Damuda fossils,* when speaking of Gangamopteris cyclopteroides from 

 the Barakars being identical with the species in the Talchirs. 



In another paperf I have described another Gangamopteris from the 

 Kamthis as Gangamopt. Hughesi, which is different from, though closely 

 related to, the species from the Barakars and Talchirs, a wider venation 

 constituting the difference. 



I now describe a third, differing from both of these by its very wide 

 net- venation. 



I think it will not be considered useless and superfluous to repeat 

 that this genus Gangamopteris occurs in true mezozoic rocks in Victoria, 

 and that nothing of the kind is as yet certainly known from the lower 

 portion of the New South Wales coal-strata. 



Our new Gangamopteris is again a form to which some analogies 

 are to be found in the living flora. 



Gangamopteris Whittiajsta, n. sp., PI. XX, Figs. 3 — 4. 

 Fronde simplici, late ovato subrhomboidali inaequilaterali, integer- 

 rima, obtuse acuminata ; costa nulla, sulco medio tantum indicata ; nervis 

 ceteris omnibus e basi duobus in directionibus marginem versus radiantibus, 

 omnibus anastomosantibtts, retia valida, oblonge hexagonalia aut polggo- 

 naliaformantibus. Fructificatione non obvia.
