268 Field Columbian Museum — Reports, Vol. II. 



and the West Indies has been finished, and is now ready for pubHcation. 

 This publication shows what the Department of Ornithology lacks, 

 what it possesses, and of what it has duplicate specimens. The study 

 collection in the Department of Zoology has been put in systematic 

 order and correctly labeled. All specimens placed on exhibition 

 have been correctly labeled and all new material inventoried. The 

 year's work in the Museum on catalogues and inventories is shown in 

 detail below:

Expeditions and Field Work. — After a cessation of two years, field 

 work for the collection of vertebrate fossils was resumed during the 

 present year. The work was in charge of Assistant Curator Riggs, who 

 spent, with a party, about four months in the Jurassic and Cretaceous 

 outcrops of Montana and South Dakota. Much new and valuable 

 material, amply repaying the cost of the expedition, was obtained. 

 Of this the most important for exhibition purposes was one nearly 

 complete skull and partial skeleton of an individual of the huge horned 

 reptile Triceratops. Four less complete skulls and parts of skeletons 

 of the same genus were also obtained. Other material of Value in- 

 cludes remains of three individuals of the long-necked swimming rep- 

 tile Plesiosaurus, portions of which will be available for exhibition, 

 and all of which is of scientific value. About 25 specimens of a sea- 

 crab from the Upper Cretaceous were secured, and some Mosasaur and 

 Claosaur remains. During the month of September about 12,000 

 specimens of invertebrate fossils were collected by Mr. Slocom in the 

 Silurian and Devonian localities of western New York. The prin- 

 cipal localities visited were East Bethany, Moscow, Lockport, Roches- 

 ter, and Niagara Falls. At East Bethany and Moscow excellent series 

 of the fossil corals for which these localities are noted, were obtained, 

 the specimens including representatives of more than twenty species, 

 and ranging in size from fourteen inches in diameter down. Several 

 thousand specimens of brachiopods, bryozoans, gastropods, and tri- 

 lobites were also procured. At Lockport, Rochester, and Niagara
