146 REPORT OF NATIONAL MUSEUM, 1887. 



terial was found to contain five species, all new to science. These are, 

 Cupressinoxylon, with four species, and Araucarioxylon, with one species. 

 The results are embodied in a report which contains about 150 manu- 

 script pages and is illustrated by 7 plates. It will be published as a 

 bulletin by the U. S. Geological Survey in connection with reports by 

 Mr. W J McGee and Prof. W. M. Fontaine on the geology and paleon- 

 tology. In the preparation of this paper almost the entire literature of 

 the subject was examined, and a brief resume, from its first mention in 

 literature down to the close of the year 1886, is included as an intro- 

 duction to the paper. 



A great amount of fossil wood is in the possession of the National 

 Museum, which Mr. Knowlton proposes to investigate as opportunity 

 may permit, since nothing is now known regarding its internal struct- 

 ure or botanical affinities.
