20 ANNUAL REPORT OF THE 



Science. A very important and welcome addition to the collec- 

 tion of graptolites is his large series of well-preserved specimens, 

 from the typical locality of the Levisian. This horizon and locality 

 was quite unrepresented in the Museum before Mr. Clark began 

 this work. 



Other accessions during the year have been the following dona- 

 tions: 3 lots of Palaeozoic fossils from Yunan, China, (Mr. J. 

 Graham), through Dr. Thomas Barbour; 5 lots of Lower Ordovi- 

 cian fossils from British Columbia, (Mr. F. P. Shepard) ; 5 boxes 

 Ordovician fossils from southern Quebec, (Mr. J. H. Bradley, Jr.) ; 

 and two drawers of Pleistocene shells from Nantasket, Mass., 

 (Mr. T. H. Clark). The Curator made a small collection of Lower 

 Cambrian fossils in Washington Co., N. Y.
