World birds belonging to the exhibition scries and cleaning and 

 repainting the bills and feet of others. 



The osteological preparator and his assistant were mainly occu- 

 pied in roughing out skeletons from fresh specimens received from 

 the National Zoological Park and elsewhere, in preparing a series of 

 orang skeletons received from Dr. \Y. L. Abbott, and in cleaning 

 mammal skulls. Many of the last mentioned were large, and the 

 fresh specimens from the Zoological Park included such forms as the 

 camel, /ebu, sea wolf, thar, markhor, and rhea. 



The chief modeler and general preparator was engaged princi- 

 pally in overhauling and completing the insect exhibit, in cleaning- 

 corals, and in preparing plaster models of various subjects. An im- 

 portant work was the restoration of the jaws of two fossil porpoise-, 

 one of which was a type specimen. 



In the department of geology the systematizing of the petro- 

 graphic material received from the U. S. Geological Survey, and the 

 separation and labeling of the duplicates has advanced rapidly. This 

 collection is now in better condition than ever before. The entire 

 exhibition series of minerals and gems was overhauled and cleaned. 



The arrangement of the Pate and Ulrich collections of fossil 

 invertebrates, two of the largest accessions of the year, required a 

 large amount of attention, a total of L2,368 specimens having been 

 numbered and registered. 



Aside from the preparation of specimens, the work in the section 

 of vertebrate paleontology consisted largely in designating the types. 

 cotypes, and illustrated specimens, completing the records, preparing 

 card catalogues, and revising the manuscript and correcting the 

 proofs of the Type Catalogue Bulletin. For the first time in the 

 history of the department it is possible to state with comparative 

 certainty the nature and whereabouts of the type material in this: 

 section. The contents of 123 boxes, received from Dr. J. B. Hatcher 

 and Mr. C. H. Sternberg, upward of twenty years ago. have been 

 cleaned and repaired, and are now ready for the preparation of 

 mounted specimens or for use as duplicates. This collection con- 

 sists largely of the remains of the fossil rhinoceros. Teleoceras fos- 

 siger, and comprises 10,500 bones in various slates of preservation. 

 With this material was discovered a nearly complete skeleton of a 

 new species of small horned rodent. Seventy-eight storage tray- of 

 Titanotherium material were cleaned and sorted, and satisfactory 

 progress was made in working up the Camptosaurus remains, among 

 which were discovered a fairly complete skeleton of ('. dispar, and 

 sufficient portions of the type specimen of C. minus to make a full 

 restoration of this form. 



The preparator in the division of geology has been occupied, as 

 heretofore, in cutting sections and making casts, and in the general
