PALEOXTOLOOICAL COLLECTJOSS IX THE VICIMTY OF BOSTON 

 BY PERCY E. RAYMOND 



(Ahstract) 



The Boston Society of Natural History has a small but interesting series 

 of the fossils of New England, among which is one of unusual importance, the 

 type of Paradoxidcs liarlani. 



There is no public exhibition of fossils at the Massachusetts Institute of 

 Technology, but a number of collections may be consulted there, particularly 

 the Pleistocene shells from about Boston. 



At the Museum of Comparative Zoology at Harvard there are very large col- 

 lections of invertebrate fossils and excellent series of some groups of verte- 

 brates, especially fishes. Noteworthy among the invertebrates are the follow- 

 ing : Schary and Barrande collections from the Paleozoic of Bohemia ; Schultze 

 collection from the Devonian of the Eifel ; Haeberlein collection from Solen- 

 hofen ; Dyer, Day, Taylor, and Walcott collections from the Ordovician and 

 Silurian of America ; Wachsmuth collection of crinoids and a very large col- 

 lection of European cephalopods and other mollusca. Among the vertebrates 

 are mounted specimens of moas and edentates, some unique birds from the 

 Tertiary, amphibians and reptiles from the late Paleozoic of Texas and Scot- 

 land, etcetera. 



The increasing use and the value of such microscopic organisms as the 

 foraminifera in stratigraphic work was then described. The paper was 

 discussed by Dr. John M. Clarke, with replies by the author. 



VALVE OF FORAMINIFERA IN STRATIGRAPHIC CORRELATION 

 BY JOSEPH A. CUSHMAN 



(Abstract) 



The foraminifera have not been greatly used in correlation work in America ; 

 workers have been lacking and collections few. In recent years, however, the 

 United States Geological Survey has accumulated many collections from the 

 Coastal Plain region, Panama, and the West Indies which are rich in fossil 

 foraminifera. 



A study of some of these has already proved that the foraminifera are ex- 

 cellent for use in stratigraphic correlations, and further study will probably 

 result in numerous detailed faunas which can easily be distinguished from one 

 another. 



The author of the next paper presented a discussion of the importance 

 and significance of the various species of the gastropod genus Orthaulax, 

 illustrating his remarks by lantern slides.
