This small collection of Devonian fossils is of interest, as it shows 

 the extension of the Devonian fauna into soul hern-central Nevada. 



172&G. From the U. S. Geological Survey, through Charles D. Walcott, in charge 

 Division of Paleozoic Invertebrate Paleontology, 3,500 specimens of 

 fossils from Devonian and Silurian strata of southern Indiana and 

 northern Kentucky. This material has been labeled, with locality 

 and formation, and distributed through the main collection to be 

 studied when reviewing that collection. 



WORK ON COLLECTIONS. 



The direct work on the collections of the Museum has been the 

 recording, identifying, and labeling of the material mentioned under 

 M accessions," and a continuation, as opportunity offered, of the arrange- 

 ment of the old collections of the Smithsonian Institution. The latter 

 work has been very limited, owing to the writer's position as paleontolo- 

 gist in charge of the paleozoic paleontology of the U. S. Geological 

 Survey, requiring him and his assistants to devote the most of their 

 time to original work in connection with the Survey. This work will, 

 in a large degree, inure to the benefit of the Museum collections, as the 

 material studied contains many new types and large numbers of species
