RESEARCH COLLECTIONS 85 



erous from the Mississippi Valley; the Gebhard collection from the 

 Lower Devonian of the Schoharie Valley; the Taylor collection 

 from northern New York; the Haeberlein collection of choice crus- 

 taceans, cephalopods, and other fossils from Solenhofen; the Eser 

 collection, rich in the invertebrates of Europe; the numerous am- 

 monites of England, purchased from B. M. Wright; the Michelotti 

 collection of Tertiary fossils from Italy; the Campiche collection and 

 the Boucault collection, both abounding in Tertiary mollusks; the 

 large collections of European fossils obtained from Fritsch, Bronn, 

 and Duval; altogether providing us with a remarkable assemblage of 

 European invertebrates. Other collections which have added 

 greatly to the value of the aggregate are those of Robert Tracy Jack- 

 son, gathered during his many years at Harvard; Tertiary fossils 

 collected by W. B. Clark and J. B. Woodworth; and the great mass of 

 material collected by Nathaniel Southgate Shaler on his expeditions 

 to Anticosti, the southern states, and Europe. Among smaller but 

 important collections should be mentioned one purchased from 

 James Hall, and an excellent series of ammonites, including some 

 types, which came from S. S. Buckman. Another small but impor- 

 tant collection is that brought from California by J. D. Whitney, 

 which contains some of Gabb's types. 



The collection of Protozoa is small, but we fortunately have ma- 

 terial from several European localities not now available to the 

 collector. The small collection of sponges is fairly representative, but 

 should be enlarged. The Hydrozoa include a good representation 

 of Ordovician graptolites of eastern North America and Sweden, 

 and from the Silurian of Bohemia. These three collections together 

 occupy about two hundred drawers. 



The collection of corals is a large one, occupying about eight 

 hundred and fifty drawers. There is a very large representation of 

 Paleozoic corals of both America and Europe, and a smaller number 

 from the Mesozoic and Tertiary of these continents. Its outstanding 

 feature is the Davis collection from the Falls of the Ohio, which 

 contains many types. 



Worms are represented by only a small collection, these animals 

 not being common as fossils. The recent accession of a large number 

 from the Mid-Cambrian of British Columbia might be mentioned. 

 There is a large collection of bryozoans, occupying about one hun-
