﻿l6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 78 



The black shales of the Lucllowville division of the Hamilton 

 were found to contain often myriads of small brachiopods and 

 pelecypods. The Tichenor limestone forming the base of the Hamil- 

 ton is also extremely fossiliferous while the Moscow shales above, 

 abounding' in fossils, can be distinguished by their slightly grayer 

 color. Then comes a gap in sedimentation, for the Tully limestone, 

 forming the base of the Upper Devonian, is separated from the 

 underlying Moscow shale by an unconformity. The very charac- 

 teristic blocky Genesee shales follow the Tully limestone as shown 

 in figure 20. 



Abundant collections were made in all the fossiliferous zones 

 and with their help, it has been found possible to accurately place 

 in this section most of the many fossils in the Museum's series 

 previously obtained from this area. 



GEOLOGICAL FIELD-WORK IN EUROPE 



Dr. Charles E. Resser, associate curator of paleontology, U. S. 

 National jMuseum and Dr. E. O. Ulrich, associate in paleontology, 

 were members of the Smithsonian-Princeton expedition to Europe 

 during the summer of 1925 for the purpose of studying the more 

 important outcrops of the lower Paleozoic beds. The other mem- 

 bers of the party were Prof. R. M. Field and Mr. R. M. Fulle of 

 Princeton University and Mr. R. J. Beede of Williams College. 

 Prof. Field kindly offered the use of his automobile, which made 

 it possible to get about readily and to reach many places off the 

 usual travel routes. The route followed by the party covered more 

 than 7,500 miles by automobile alone, through central England, 

 Wales, and the extreme north coast of Scotland, the Scandinavian 

 countries, Germany, Czechoslovakia, Austria, Switzerland, and 

 France. 



Work was begun in Shropshire, where Mr. Edgar Sterling Cob- 

 bold of Church Stretton conducted the party to the various localities 

 at which he has done much valuable geological work. A few days 

 later he was again the guide to the famous Stiper Stones region on 

 the west side of the Longmynds. Some time was spent also in 

 studying the sections along the Onny River, in company with Mr. 

 B. B. Bancroft. In Wales, Prof. T. C. Nicholas of Cambridge 

 and Prof. O. T. Jones of Manchester guided the party about the 

 Harlech Dome, on St. Tudwals Peninsula and in Central Wales. At 

 Durness, on the extreme northwest coast of Scotland, a large series
