DEPARTMENT OF INVERTEBRATE FOSSILS (PALEOZOIC). 



The honorary curator, Mr. C. D. Walcott, has been obliged to devote 

 his time almost exclusively to work connected Avith the U. 8. Geological 

 Survey. The department cooperated with the Survey in the prepara- 

 tion of an exhibit for the World's Columbian Exposition. Such time 

 as could be spared to laboratory work was given to the preparation of 

 a collection to be exhibited at the World's Columbian Exi)osition. A 

 description of this exhibit is given at the close of this report. 



The year's work upon the collections was mainly in the direction of 

 working out and putting in condition for study the collections that had 

 previously been made by the Geological Survey. Over 200 drawers of 

 Upper Cambrian fossils have been worked up, preparatory to study in 

 connection with the preparation of a monograph on the Upper Cam- 

 brian fauna. A large number of Middle Cambrian fossils were received 

 from the field, cleaned, and record numbers entered upon them. None 

 of this material, liowever. was transferred to the National Museum, as 

 1 thought it desirable to complete the study of the same before trans- 

 mitting it. 



In the laboratory, attention was given to painting the record numbers 

 on the specimens belonging to the accessions, and to the recording' of 

 material which will be transferred from the Geological Survey as soon 

 as the work upon it is completed. 



The publications of the year based on Museum material are noticed 

 in the Bibliography. 



The catalogue numbers taken up were from 24153 to 24311, both 

 inclusive. About 1,200 specimens have been added to the collection. 



Owing to the pressure of other work, a number of the recent acces- 

 sions to the Museum exhibition series have not yet been entered, but 

 special instructions have been given to attend to this matter early in 

 the next fiscal year. 



Among- the most interesting additions were the collections made by 

 Mr, Walcott. One hundred and fifty specimens of fossils of the Oriskany 

 formation, at Cumberland. Md., and 100 specimens of Lower Devonian 

 corals, from Genesee County, N. Y., from the Geological Survey. Also a 

 large collection of 325 individual crinoids, together with 12 magnificent 

 crinoid slabs from the Lower Carboniferous at Crawfordsville, Ind., from 

 Charles E. Bcecher, Yale College, New Haven, Conn. Dr. A. L. Bene- 

 dict, of Buffalo, N. Y., sent 24 specimens of fossils (tharacteristic of the 

 water-limestone of Buffalo, and L. W. Stuart, Monmouth, Iowa, a con- 

 siderable collection of Niagara fossils from jMonniouth, Iowa. 



It was decided that the Museum should unite with the U. S. Geolog- 

 ical Survey in the preparation of a paleontological exhibit for the 

 World's Columbian Exposition. A large number of specimens belong-
