REPORT ON THE DEPARTMENT OF INVERTEBRATE FOSSILS (MESOZOIC) 

 IN THE U, S. NATIONAL MUSEUM, 1887. 



By C. A. White, Honorary Curator. 



By far the greater portion of my time, and of my assistant, has been 

 devoted to the performance of work connected with my duties as pa- 

 leontologist of the U. S. Geological Survey, so that comparatively little 

 has been accomplished in the way of Museum work. During the year, 

 however, the card catalogue of all the material belonging to the Museum 

 and now in the custody of the department was completed, and the en- 

 tire collection is now identified, labeled, and ready for exhibition. 



Only twelve accessions were received, among the most important of 

 which were the following : 



Four specimens of Belemnitella quadrata, from Prof. 0. Schluter. A 

 collection from the Pebas group of the Amazon, sent by Dr. O. Bottger. 

 Seven specimens each of Cyclostoma antiquus and C. tricarinata, and 

 two specimens of Cyrena lirata, from Prof. C. L. F. Sandberger, of 

 Wiirzburg, Germany. A collection of 63 specimens from Prof. M. Neu- 

 mayr, for which a collection was sent him in exchange. Eight speci- 

 mens from Mr. Edward Crane, Brighton, England. A collection from 

 the Laramie group, sent by C. R. Beiderman. Alaskan cretaceous fos- 

 sils, from E. E. Howell. A collection of fossils from Oregon, sent by 

 Prof. T. Condon. A collection of fossils, from Dr. J. S. Newberry, of 

 Columbia College, New York City. 



The number of the last entry for June, 1886, was 19970 ; that for 

 June, 1887, 21003. 



Five papers were published by the curator during the year, and are 

 noticed in Section iv of the report.
