122 REPORT OF NATIONAL MUSEUM, 1914. 
logue, by the aid of which any particular lot of Tertiary fossils can 
readily be found, is in course of preparation. Additional room space 
allotted to Dr. T. W. Vaughan also made requisite a complete rear- 
rangement of the Tertiary corals, which was carried forward as far 
as cases were available. 
The amount of research work accomplished was extensive. Secre- 
tary Charles D. Walcott completed and published his studies of the 
Dikelocephaline trilobites, and on the Cambrian and its problems 
in the Cordilleran region. He also continued work on the pre-Cam- 
brian Algonkian algal flora of North America, which has yielded 
unexpected results. Dr. William H. Dall finished a preliminary 
identification of the Tertiary fossils from the Panama Canal Zone, 
made good progress with his investigation of the Pacific coast Ter- 
tiary, and had about ready for submitting a monograph on the mol- 
luscan fauna of the Orthaulax pugnax zone of Florida. 
Mr. Frank Springer completed the descriptive matter for the 75 
quarto plates illustrating his monograph on the Crinoidea flewibilia, 
and brought the preparation of the text to such a point that he soon 
expects to send it to the press. The illustrations for his monograph 
on the crinoid genus Seyphocrinus, which had been delayed, were 
finished, and the work will shortly be ready for publication. With 
these important investigations disposed of, Mr. Springer expects to 
continue his studies on the Silurian crinoids of western Tennessee, 
the classic locality from which he has large collections. The illus- 
trations for a large part of this work have already been made. Prof. 
William B. Clark, of Johns Hopkins University, and Dr. M. W. 
Twitchell, assistant State geologist of New Jersey, have collaborated 
on a monograph based mainly upon Museum specimens of the Meso- 
zoic and Cenozoic Echinodermata of the United States, which will 
be published by the Geological Survey. 
Dr. E. O. Ulrich, associate in paleontology, spent considerable time 
in a study of the early Silurian collections of the Museum, the re- 
sults of which have been embodied in a bulletin entitled ‘“‘ The Medina 
and Clinton Formations of the Appalachian Valley,” which has been 
offered to the Geological Survey for publication. Dr. Ulrich and 
the curator also prepared the text for the Cincinnati Folio of the 
Survey, in which many Museum specimens will be illustrated. 
The principal contribution by the curator, Dr. R. S. Bassler, was 
in the form of a bulletin of 500 or more pages entitled “ Bibliography 
and Synonymy of American Ordovician and Silurian Fossils,” which 
contains, in addition to the matter indicated by the title, a register 
of the Museum’s rich type collection of these two periods. The 
curator also completed a report on the early Silurian Bryozoa and 
Ostracoda of the island of Anticosti, Canada, based upon specimens 
now the property of the National Museum, which will be published
