MUSEUM OF COMPAEATIVE ZOOLOGY. 31 



REPOKT ON THE DEPARTMENT OF VERTEBRATE 



PALAEONTOLOGY. 



By Charles R. Eastman. 



Departmental work has proceeded about the same as hereto- 

 fore, chief attention being devoted to fossil fishes. The collection 

 of fossil mammals, however, received a useful addition in a series 

 of casts presented by the Peabody Museum (Yale University) 

 through Prof. Charles Schuchert ; these casts, seventy-one in 

 number, represent specimens described by Dr. Joseph Leidy, 

 and were made many years ago by Mr. Kaeppler for Prof. 0. C. 

 Marsh. To Prof. Bashford Dean, of the American Museum of 

 Natural History, the Department also is indebted for excellent 

 casts of Polypterus, Neoceratodus, Dinomylostoma (dental plates), 

 and a chimaeroid egg-capsule from the Cretaceous of Laramie, 

 Wyoming, described by Dr. Theodore Gill in Science, 1905, Vol. 

 22, p. 601. 



A large specimen of Dapedoglossus from the Green River 

 Eocene of Wyoming was acquired by purchase, and two smaller 

 specimens were presented by Mr. Thomas Barbour. Several 

 Miocene fishes from Hazen, Nevada, collected by Mr. N. H. 

 Darton of the United States Geological Survey, were presented 

 by Mr. Darton, and a collection of over one hundred fish-bearing 

 nodules from the Devonian of Boyle Co., Kentucky, were pro- 

 cured partly by gift, from Mr. Moritz Fischer. A small example 

 of the very rare Pycnodont occurring at Monte Bolca, Pycnodus 

 platessus Ag., was bought of Deyrolle, ex. coll. Huguenin et 

 Homo. 



The following publications were issued during the year : — 



Fossil Avian Remains from Armissan. Mem. Carnegie Museum, 

 1905, Vol. 2, p. 131-138, pi. 13-16. 



Greek Ideas of Vulcanism. Pop. Sci. Monthly, 1905, Vol. 67, p. 555- 

 560.
