1 1 GANGAMOPTERIS. 



V. 2753'-/. In addition to a frond of Noeggerathiopns, an orbicular 

 frond, 2 - 4 cm. long and 2 - 8 cm. across, occurs on this specimen. 

 It appears to have no well-defined midrib, although the median 

 nerves anastomose. It is probably identical with this species. 



Cullen Bullen, near Mudgee. 



Pres. by W. II. Shrubsole, Esq., 1892. 



V. 7213. A piece of grey shale containing a number of fairly 

 pei'fect fronds of Glossopteris Browniana, and a small spathulate 

 frond, 3 cm. long, apparently without a midrib. 



Tort Stephens. 



Fronds of Gangamopteris cyclopteroides from Tasmania. 



V. 3776///. PL III, Fig. 4. 



A small oval-spathulate frond, 3 cm. long, and 17 mm. across at 

 its widest point. The apex and base are imperfect. The 

 nervation is well preserved, there being no midrib, but a few 

 sub - parallel, anastomosing median nerves. The lateral veins 

 mostly spring from the median series, and are arched. Other 

 fragments of similar fronds, and of Glossopteris occur on the same 

 specimen. 



Mersey Eiver. Pres. by T. Stephens, Esq., 1898. 



V. 3776//. PL III, Fig. 5. 



A somewhat narrower leaf than the preceding specimen, 

 measuring 3 cm. long, and 15 mm. across. The apex is obtusely 

 pointed. Like the last example this leaf recalls the scale-fronds of 

 Glossopteris, from which, however, it differs in being considerably 

 larger, less pointed at the apex, and flat instead of concave. 

 Several other fragments of a similar type occur on the same 

 specimen. 



Mersey River. Pres. by T. Stephens, Esq., 1898. 



V. 3776 s. An apical portion of a frond apparently without 

 a midrib. A slight median groove is present. The lateral 

 nervation is acute, and the meshes rather narrow. 



Mersey ltiver. Pres. by T. Stephens, Esq., 1898. 



V. 3776/!. This specimen shows a mass of fronds, some of which, 

 appear to belong to Gangamopteris, as they have no definite midrib, 

 but a series of sub-parallel median veins. 



Mersey Liver. Pres. by T. Stephens, Esq., 1898.
