188 REPORT OF NATIONAL MUSEUM, 1888. 



Remarks on the Genus Aucella, -with especial reference to its occurrence in Califor- 

 nia. (Monograph xiii, U. S. Geological Survey, pp. 226-232, pis. iii and iv, by Dr. G. 

 F.Becker.) 



On the Geology and Physiography of a portion of northwestern Colorado and ad- 

 jacent parts of Utah and Wyoming. (Ninth Annual Report U. S. Geological Survey.) 



No attempt Las been made to separate the collections into a reserve 

 and exhibition series. The type specimens are kept apart trom the 

 other material and will form the larger part of the exhibition series. 

 Quite a number of duplicates can be selected from the collections for 

 exchange, but no exchanges of any consequence have yet been made. 



The collection as a whole is in a very good condition. Most all the 

 material belonging to the Museum has been identified, labeled, and 

 properly entered on the Catalogue. The space on the northeast balcony 

 of the Smithsonian building, formerly used for storage, has been given 

 up, and the material in the study series has been moved into the south- 

 east court of the Museum. 



Owing to the limited space in the southeast court a large part of the 

 material has been stored iu the old Armory building.
