148 GEOLOGY. 



while other species of the same groups, with Equisetaceae in addition, 

 mark the Eajmahal horizon as Liassic. The Panchet beds, before con- 

 sidered Triassic, are determined as Keuper. The Damuda beds, in spite 

 of some forms being found also in the Palaeozoic coal-strata of Australia, 

 are thought, from the majority, to be L. Triassic. The Talchir beds 

 are but the lower part of the Damuda formation, or a lower horizon of 

 L. Triassic. The following new species are described ; — Schizoneura 

 Goiidwanensis, Neuropteris valida, Actinopteris Bengalensis, Oangamo- 

 pteris cyclopteroides. 



The last part meets Mr. Blanford's arguments (see p. 146) by denying 

 that it is clearly proved by moUuscan remains that the Kach beds are 

 U. Oolitic, the 4 Portlandian Cephalopoda being insufficient in face of 

 other pala3ontological facts.. With regard to the L. Gondwana groups, 

 the author lays stress on the passage between them and the U. Gondwana 

 groups, and maintains, by means of a more detailed account of the 

 plants, the Mesozoic and even the Triassic character of the Damuda 

 flora. As to the analogy of the Damuda with the Australian beds, the 

 only likeness is to the " upper coal-measures " of Australia, and there 

 is no proof of the Palaeozoic age of these ; on the contrary, he would 

 count them as Triassic — only the L. Coal Measures of that countrj^ and 

 rocks below them being Carboniferous. Then follows a description of 

 the flora of the Jabalpur group in S. Eewah and Satpura, which is 

 shown to be of the same age as the Kach rocks and of the L. Oolite of 

 Yorkshire. The following new species are described : — Macrotanio- 

 pteris Feddeni, Oangamopteris Hughesi, Sagenopteris StoliczJcana, Glosso- 

 zamites StoliczTcanus. P. D.

A synopsis of previous writings on the subject is given. The older 

 metamorphic rocks underlie all ; they vary in character, generally in 

 bands, which can be traced for some miles ; the prevalent strike is N.W. 

 by N. There is granitoid gneiss, hornblendic or micaceous, and more 

 or less porphyritic ; the bedding is sometimes obliterated, sometimes 

 distinct ; in one case diagonal foliation or false bedding was observed in 

 the gneiss. Of schistose rocks there are five varieties, including haema- 

 tite schist ; in this last there are ferruginous folia which are sometimes 

 entirely composed of haematite, but sometimes consist merely of grains 

 of it combined with siliceous particles; this may pass into an iron - 

 stained quartzite. Crystalline limestone occurs, though rarely, as well 

 as dolomite. These metamorphic rocks are traversed by dykes of 

 diorite, by granitic veins, and by quartz reefs. F. D.
