outcropping in this quadrangle from the uppermost beds of the 

 Silurian to the top of the Devonian. Diagnostic fossils for each 

 formation are also listed. The map gives the areal distribution

3. Second Report of the Director of the Science Division, 

 1905. N. Y. State Mas., 19(>6, 99 pp.— This is the 59th report 

 of the New York State Museum and the 2nd report of the Direc- 

 tor of the Science Division, John M. Clarke. It deals with the 

 work done and in preparation throughout the various divisions 

 of the State Museum during the year 1905. Of particular 

 interest to stratigraphers is the announcement, — "It is quite 

 probable however that the Oswego sandstone [heretofore always 

 accepted as Silurian] represents a near-shore condition, which 

 was unfavorable for life, but farther west the Richmond fauna 

 flourished under more suitable conditions." In other words, it 

 is probable that the Oswego and Medina formations are the clos- 

 ing formations of the Ordovician. This is the view maintained 

 by Ulrich of the IT. S. Geological Survey, during the past three 

 years, based on the Medina stratigraphy of the southern Appa- 

 lachian. 



Another striking correlation is that the Shawangunk conglom- 

 erate is not of Medina (Oneida) age, but " represents the 

 invading basal member of the Salina formation in the eastern 

 part of the State." c. s. 



4. The Upper Ordovician Hocks of Kentucky and their 

 Bryozoa ; by John M. Nickles. Bull. 5, Kentucky Geol. Sur- 

 vey, 1905 (not received until July, 1906), 64 pp. and 3 pis. — 

 This report describes the rocks of the Cincinnatian series and 

 lists the Bryozoa of the various formations as found in Ken- 

 tucky along the Cincinnati arch. Twenty-eight species are 

 described, of which five are new. The illustrations show the 

 macroscopic characters of the species. c. s. 



5. 7'Ae Chazy Formation and its Fauna ; by P. E. Ray- 

 mono. Ann. Carnegie Mus., iii, July, 1906, pp. 498-598. — This 

 is the first article of a series of papers in which the author pro- 

 poses to describe the stratigraphy and faunas of the Chazy as 

 found in northeastern North America. The part now at hand 

 deals with the stratigraphy of the various areas and lists of the 

 fossils occurring in the various beds. The author's main conclu- 

 sions are as follows: — 



" This fauna shows a decidedly closer affinity with the fauna 

 of the Black River and Trenton formations of New York and 

 Canada than with the Beekmantown of the same regions. The 

 strong Mohawkian facies of the Chazy fauna suggests that the 

 Chazy formation should be taken out of the Canadian, the Beek- 

 mantown and Chazy having very little in common." There is 

 but one species common to the two formations. " While the 

 Black River and Trenton formations have only a few species in 

 common with the Chazy, yet when the fossils are compared with 

 one another it is found that almost every one in the Chazy is
