REPORT ON THE PAL^ONTOLOGICAL DEPARTMENT. 



By Alpheus Hyatt. 



In connection with work on the Carboniferous Cephalopods of 

 Texas, which will be shortly published, the Assistant has classi- 

 fied and renamed the corresponding collection in the Museum, 

 and made a number of preparations showing the stages of growth 

 of different species and genera. 



The Whitney Collection of California fossils presented to the 

 Museum this year has been looked over and in part studied. It 

 is small, but it contains some fossils of extraordinary interest. 

 Among those that may be mentioned are a number of the types of 

 Gabb's descriptions of California fossils. The value of these origi- 

 nals, especially with reference to the history of Mesozoic Geology 

 of the West cannot be overestimated. 



Through Professor Pickering the Museum has also received a 

 small collection of South American fossils collected bv Mr. A. E. 

 Douglass. 



The department is indebted to Dr. R. T. Jackson for work upon 

 the collections, and the superintendence of the work of Miss Clarke 

 in mending broken fossils of the Gebhard and other collections.
