museum. Doctor Maury, as a result of her studies, published 

 in the September number of the American Journal of Science 

 a summary paper on the correlation of the Tertiary Forma- 

 tions of Porto Rico with those of the other Antillean islands, 

 and a longer paper entitled "Tertiary Mollusca from Porto 

 Rico and their Zonal Relations," including descriptions of some 

 fifty new species and varieties, is in press for the publications 

 of the New York Academy of Sciences. Doctor Marjorie 

 O'Connell did some preliminary work on the Foraminifera, 

 but for lack of apparatus could not complete the studies within 

 the time allotted for them and they were dropped. Associate 

 Curator Reeds has in hand the completion of his contour map 

 of the Caribbean Sea and a popular scientific description of 

 the seismograph. The Museum has received from Doctor T. 

 Wayland Vaughan, of the United States Geological Survey, an 

 extensive series of the rocks of the Lesser Antilles which the 

 Curator is to work up, in connection with further intensive 

 study of his own Museum collections from the same region, in 

 making a comprehensive review of the igneous geology of the 

 islands. 



The only field work done by the Department this year was 



that by the Curator in connection with a visit to the lead and 

 zinc mining region of northeastern Oklahoma in 



Field Work February and March for the purpose of collect- 

 ing material from the lead-ore (galenite) lining 



of a grotto in the mine of the Laclede Lead and Zinc Mining 



Company's property at Tar River, Oklahoma. 



Among the gifts received by the Department, mention should 

 be made of the large genetically arranged series of specimens 

 illustrating coal and its derived products as- 

 sembled with expert care and donated by The 

 Barrett Company. From Mr. Edward J. Foyles has come a 

 series of fossils and rocks from the Department of Doubs, 

 France, made by him while serving with the United States 

 Army. Four enlarged models of trilobite restorations have 

 been prepared for us by Doctor Elvira Wood.
