Coal-field, which extends from Dover to Deal, Wingham, and near to 

 Ebbsfleet ; (2) the structure of the ground between the borings at 

 Dover and Ropersole, and between those of Fredville and Brabourne ; 

 (3) a map of the buried Silurian and Devonian rocks in South- 

 Eastern England ; and (4) a map of the coal-fields and tectonic folds 

 of Southern England and Wales. He discusses the general structure 

 of this southern area, and then gives details of the experimental 

 borings, some of which proved the absence of Coal-measures, as at 

 Chilhara, in the valley of the Stour above Canterbury, and at Bobbing, 

 near Sittingbourne, where Silurian rocks were found directly beneath 

 Jurassic strata. Some lists of fossils are given, and the author 

 recommends that farther trials for Coal-measures should be made in 

 the district south of Croydon. 



XII. — Brief Notices. 

 1. Geology of Victoria, and Tasmania. — Mr. Frederick Chapman 

 has contributed Reports on the Middle Devonian fossils of the Buchan 

 district and on the Silurian and Devonian fossils of the Mitta Mitta 

 district, Victoria (Records Geol. Survey, Victoria, vol. iii, pt. ii, 

 1912). Among the Middle Devonian fossils of Buchan are Favosites 

 lasaltica, Goldf., var. moonhiensis, Eth. fil., Conocardinm, Murchisonia, 

 and Cheirurus (?). The age of the fossils of Mitta Mitta cannot be so 

 definitely determined ; some may be Silurian, others, including 

 Cyathophylhim and Favositefi, are probably Devonian. To the same 

 publication Mr. Chapman supplies a note on the correlation, by 

 means of plants, of the Tasmanian and Victorian Jurassic strata. He 

 has also recently paid special attention to the Phyllocarida, which 

 seem to occur fairly abundantly in the Ordovician Shales of the colony, 

 and Symenocaris heplurnensis is described as new. Some well- 

 preserved specimens of Haliserites decheniamis, Goepp., have likewise 

 been figured and described by Mr. Chapman, who in the same volume 

 gives an illustrated description of the fossil scale of a Ceratodus from 

 the Jurassic beds of Kirrak, South Gippsland, calling attention to the 

 interesting point that this is the first occurrence of a fossil scale of 

 the fish. 



2. Sphenophyllu3i in Australia. — In a report on the Mount 

 Mulligan Coal-field (Geol. Surv. Queensland, 1912, publ. 237, p. 11), 

 Mr. Lionel C. Ball reports the discovery in the shales of Siberia 

 Camp of the pteridophyte Sphenophyllum speciosmn in association with 

 Glossopteris. The single individual obtnined is described and figured. 

 Hitherto Australia has yielded only a single very imperfect specimen 

 of Sphenophyllum, which came from the Lower Carboniferous beds 

 of Port Stephens, N.S.W. The finding in Northern Queensland of 

 8. speciosum, which is characteristic of the Lower Gondwana beds 

 of India, is of great interest as affording another link in the chain of 

 evidence connecting Australia, India, and South Africa in Permo- 

 Carboniferous times, byway of the sunken continent Goiidwana-land. 

 Figures of Glossopteris, Sphenophyllum, and Sphenopteris are given in 

 support of the age of the beds, as well as sections, maps, and 

 illustrations.
