evidence; His enclosure of authors' names within round brackets is 

 not consistently carried out ; but that is a trivial matter, and one 

 gladly recognises that the meaning of brackets is understood. What, 

 if we may judge from the list of helpers, is not understood is that 

 before proposing new species and varieties the type-specimens of 

 recognised species should be referred to, and that the I'ich collections 

 of the British Museum are open to all serious students. The omission 

 (so it seems) to consult them is not a ti'ivial matter. 



2. South Africa. — Further South African matei'ial reaches us in 

 the shape of papers by W. D. Lang on Polyzoa and Authozoa from 

 the Upper Cretaceous Limestone of Xeed's Camp, Buffalo lliver, and 

 H. Woods' paper on Echinoidea, Brachiopoda, and Lamellibranchia 

 from the same district. Lang's researches lead him to conclude that 

 the age of this deposit is Senonian or Danian, and Woods' refers it to 

 " a late stage in the Chalk". F. 11. C. Bced has examined a large 

 series of additional fossils from the Bokkeveld Beds, and finds that his 

 conclusions as to the characters and relations of these beds do not 

 require any modification in consequence of the new material received. 

 He gives a complete list of this interesting Devonian series and 

 notices all the new species. Dr. Broom describes the greater part 

 of a skeleton of Propappm omocratm, a Parciasaurian found in 

 1907 near Oraaff Beinet ; Alopecodou^ ITji^'naHudnis, I'rochosuchus, and 

 PardosiicJnis, four new genera of Therocephalian reptiles, and a new 

 \jii\>yvmt\\o(\o\\tRhinpsuc]tus fF/iailsi oi Permian age. All these papers 

 appear in the Annals of the South African Museum, 1908. 



Dr. A. W. Rogers has published in the Twelfth Annual Keport of 

 the Geological Commission of the Cape of Good Hope (1908) the 

 result of his survey of parts of Vryburg, Kurumau, Hay, and Gordonia, 

 a large area simple in the west and north-west, but complicated in the 

 central part where the rocks are almost completely hidden under sand. 

 Karroo beds occur in an extensive but thin layer, but beyond the 

 recent fresh -water moUusca in a few pans no fossils appear to have 

 been found. A. L. Du Toit has papers in the same publication on 

 portions of Mafeking and Vryburg and portions of Hopetown, 

 Britstown, Prieska, and Hay, and here again fossils are almost absent, 

 a few plant remains alone rewarding the surveyor. Progress is 

 steady and continuous, and in a few years time the devoted band of 

 geologists now working in South Africa will be enabled to provide 

 a geological map which will considerably advance our knowledge of 

 that interesting area. 



3. Canada. — A batch of papers from the Canadian Department of 

 Mines dated 1907 and 1908 shows the usual activity in geological 

 matters. The Similkameen district of British Columbia is described 

 ■by C. Camsell, who finds there Post-Oligocene, Oligocene, Cretaceous, 

 Post-Palaeozoic, and Palseozoie deposits, fossils occurring only in the 

 Oligocene lignites and the Cretaceous sandstones. D. D. Cairnes 

 writes on a portion of the Conrad and Wliite Horse mining districts 

 of the Yukon, and his paper, chiefly devoted to mining, contains 

 interesting particulars of the Carboniferous or Devonian, Triassic (?), 

 Jurassic, and Cretaceous sediments, all of which are shown on a map 

 accompanying the report. Dr. 11. W. Ells writes on the Landslide at
