6. Revised Nomenclature of the Ohio Geological Forma- 

 tions ; by Charles S. Prosser. Geol. Surv. Ohio, 4th ser., 

 Bull. 7, 1905, pp. i-xv, 1-36. — As the title of this paper indi- 

 cates, it revises the names applied to the geological formations 

 of Ohio, in accordance with modern usage. It is a revision and 

 elaboration of a similar paper published by the same author in 

 the Journal of Geology, Oct., 1903, pp. 519-547. 



7. Mesozoic Section on Cook Inlet and Alaska Peninsxda • 

 by T. W. Stanton and G. C. Martin. Bull. Geol. Soc. Amer- 

 ica, June, 1905, pp. 391-410, pis. 67-70. — This is a very impor- 

 tant paper describing in some detail the Upper Triassic (2000 

 feet), Lower Jurassic (1000), Middle Jurassic (1500-2500), Upper 

 Cretaceous (1000), and Tertiary (2000) strata of the Cook Inlet 

 region. The writers also illustrate a very interesting local uncon- 

 formity, which they were able to trace for about a quarter of a 

 mile. " The fact that the same fauna is found both above and 

 below this unconformity is evidence that the erosion interval 

 was geologically brief, and it probably did not affect a wide 

 area." 



8. New York Stcde Museum • Report of the Director, 190 4-. 

 John M. Clarke. 1905, pp. 1-146. — This is the report of the 

 Director of the Science Division of the Education Department, 

 the State Museum, and the State Geologist and Paleontologist, 

 for the year ending September, 1904. The report states what 

 has been done during the year, and the woi'k now in hand. 



9. The Geology of Miller County ; by S. H. Ball and A. F. 

 Smith. — Mo. Bureau Geol. and Mines, I, sec. ser., 1903, pp. i-xvi, 

 1-207, many plates and a geological map. — Describes the geology 

 of the Cambrian, Ordovician, Mississippian, Pennsylvanian, and 

 Pleistocene formations of the county. 



10. The Quarrying Industry of Missouri ; by E. R. Buckley 

 and H. A. Buehler. Ibid., II, sec. ser., 1904, pp. i-xv, 1-371, 

 many plates and a geological map. 



11. The Geology of Moniteau County ; by F. B. Van Horn 

 and E. R. Buckley. Ibid. Ill, sec. ser., probably 1905, pp. 

 i— viii, 1-104, many plates and a geological map. — There is no 

 date on the title page of this book, it being replaced by the 

 stamp of the " Typographical Union." It is to be hoped that 

 this practice will be relegated to the rear, as the date of a book 

 is worth far more to its users than the fact that the work was set 

 up by a given typographical union. 



In this volume, the geology of the Cambrian, Ordovician, 

 Devonian, Mississippian, Pennsylvanian, and Pleistocene forma- 

 tions of the county are described. 



12. Note on the use of Buena Vista as the name of a geologi- 

 cal terrain • by Charles S. Prosser. (Communicated.) — In the 

 December (1905) number of this Journal, Professor H. D. Camp- 

 bell proposes the name " Buena Vista shale," derived from a town 

 of that name in Virginia, for the upper formation of the Cam- 

 brian system in the middle portion of the Valley of Virginia
