78 REPORT OF NATIONAL. MUSEUM, 1924 



Museum's collections. It is also rich in type specimens illustrated 

 in various Wisconsin and New York reports by Mr. Teller and other 

 paleontologists. As a whole, the collection forms a stratigraphic 

 unit which fits most admirably into the scheme of arrangement 

 adopted by the division. 



A second most noteworthy gift consists of approximately 25,000 

 Early Silurian invertebrates from Clinton County, Ohio, represent- 

 ing the life work in paleontology of the donor, Dr. George M. Austin, 

 Wilmington, Ohio. Clinton County is classic ground for the excel- 

 lent and numerous fossils from the various formations of the Rich- 

 mond and succeeding groups, and Doctor Austin's efforts were de- 

 voted to assembling and accurately labeling the faunas, so that his 

 collection furnishes a complete record of the stratigraphic succession 

 of the area. 



Notable among other gifts are collections of Upper Cambrian and 

 Ozarkian fossils from Wisconsin, donated by the geological survey 

 of that State, and a full set of Middle Triassic fossils from Nevada, 

 presented by Ward's Natural Science Establishment in appreciation 

 of the services of a member of the division in identifying and label- 

 ing a large collection of similar forms. 



Ordovician and Silurian fossils from northern Michigan and St. 

 Joseph Island were collected by Dr. E. O. Ulrich; Curator R. S. 

 Bassler made collections from the Ordovician and Mississippian of 

 Tennessee and Kentucky; while Associate Curator C. E. Resser 

 made similar collections of Cambrian and Ordovician forms from the 

 Appalachian Valley of southern Virginia and from eastern Nevada 

 and Utah. 



An exchange, which added a number of type specimens of both in- 

 vertebrates and vertebrates to the collections, was arranged with 

 the Colorado College, Colorado Springs. Extensive teaching col- 

 lections of invertebrates were furnished in return for these types. 



Among the materials from foreign sources mention may be made 

 of Upper Cambrian and Lower Ordovician fossils from Sweden, gift 

 of the Geologisk-Mineralogiska Institutionen, Lund; Lower and 

 Middle Cambrian fossils from England, by exchange with Prof. 

 E. S. Cobbold, Church Stretton, Shropshire; trilobites from Norway 

 and Italy, through exchanges with the Paleontologisk Museum, 

 Christiania, and the Geological Institute, Regia University, Pisa; 

 and Tertiary fossils from Italy, by exchange with Real Istituto di 

 Geologia e Paleontologia, Florence. Dr. T. Wayland Vaughan was 

 instrumental in securing- extensive series of Australian and New 

 Zealand Tertiary fossils during the summer of 1923, including dona- 

 tions from F. S. Mann and Francis A. Cudmore, Melbourne. Plio- 

 cene fossils from Iceland were presented by Hans Schlesch, Helle-
