62 EEPORT OF NATIONAL MUSEUM, 1915. 



Stanton and Mr. T, E. Willi arc! have cared for all the Mesozoic 

 material received. Dr. William H. Dall reports, with reference to 

 the Cenozoic collections, that the work has consisted in indexing and 

 arranging the specimens in new steel cases, and in the preparation 

 of a catalogue of Pacific coast species. Dr. T. W. Vaughan spent 

 much time in the study and arrangement of the Tertiary corals, 

 which are now in fairly good condition. The curator himself de- 

 voted some weeks to the preparation of the collection of Tertiary 

 Bryozoa obtained by him in 1914 ; and Mr. Frank Springer, associate 

 in paleontology, retained supervision of the fossil echinoderms. 



Secretary Charles D. Walcott continued his researches on algal 

 and concretionary-like material in the Cambrian limestones, and 

 conducted an investigation of the Appalachian faunas, especially 

 of the Cambrian period, with a view to their correlation. A contri- 

 bution on this subject is nearly ready for publication. Definite 

 progress was also made in the study of the Cambrian trilobite fauna, 

 which has for several years been under consideration. A work now 

 in hand correlates the results of Dr. Walcott's inquiries for the past 

 ten years and brings the data into comprehensive form for the gen- 

 eral reader. Dr. William H. Dall made considerable advancement 

 with the monogi'aph of the Pacific coast Tertiary mollusks and with 

 his studies on the fossil moUuscan fauna of Panama, and prepared 

 an account of the fossil mollusks collected by Dr. T. W. Vaughan 

 along the Flint Eiver in Georgia. Mr. Frank Springer reported 

 progress on his monograph on the Crinoidea flexilnlia; his mono- 

 graph on the crinoid genus Scijfliocfinus has been completed but its 

 publication has been delayed pending further field work. Mr. E. O. 

 Ulrich was still occupied with his researches on the Canadian faunas, 

 and the curator of the division. Dr. E. S. Bassler, made good progress 

 on his monograph of the early Tertiary Bryozoa of America. Miss 

 M. J. Eathbun described the Tertiary decapod crustaceans of Pan- 

 ama, comprising 61 species, of which 38 are new to science, 3 rep- 

 resenting new genera and 1 a new family; and also the crustaceans 

 of the same group collected by Mr. L. W. Stephenson in the Upper 

 Cretaceous of North Carolina, and the like forms obtained in the 

 Leeward Islands by Dr. Vaughan. 



Prof. Charles Schuchert, of Yale University, completed his im- 

 portant work on the fossil starfishes, begun during his connection 

 with the Museum, and it has been published as a Museum bulletin. 

 Dr. T. D. A. Cockerell, of Boulder, Colo., studied the collection of 

 fossil insects from England, on which a report has been submitted. 

 Members of the Carnegie Institution of Washington frequently made 

 use of the collections, while among others who visited the Museum 

 for the same purpose were Miss Julia Gardner, of Johns Hopkins 

 University; Prof. Stuart Weller and Mr. H. E. Wilson, of the
