SPECIAL RESEARCHES. 



In the flood of routine work an occasional rest was taken for study, 

 and investigations prosecuted by the curator. 



1. On the mollusks of the Blake collection, of which the brachiopods 

 and pelecypods were completed and published ; 2. On the fossils of the 

 later Tertiary of south Florida, still in progress; 3. On a small collec- 

 tion of fragments, etc., obtained by the Jeannette expedition at Bennett 

 Island in the Polar Sea; 4. On the general Floridian and Gulf fauna, 

 still in progress; 5. On the geology of south Florida, in press; and 

 on several Arctic or sub -Arctic collections made by Mr. L. M. Turner 

 in Labrador, Mr. Nicholas Grebnitzki in Bering Sea, and by the cura- 

 tor in several parts of northern Alaska. The papers printed are enu- 

 merated in the list appended to this report. Dr. Stearns, the assistant 

 curator, has devoted some time to the study of the fossil Tryonia. a 

 small genus of the Amnicola group; of Teredo ; and of the Phoridce, or 

 Carrier shells. 



Mr. Paul Pelseneer, of the Museum at Brussels, having taken up the 

 study of the pteropods, applied for certain material to be used in his 

 studies. This, consisting chiefly of specimens of Pacific and other 

 pteropods and copies of colored drawings made from life while in the 

 North Pacific by the curator, was furnished to the Museum of Brussels 

 for his use. 



A preliminary paper describes a new genus found off the eastern 

 coast of the United States by the IT. S. Fish Commission steamer Alba- 

 tross, and further publications may be expected. 



In previous reports I have shown why it is impossible to state the 

 exact number of specimens, species, duplicates, etc., contained in the 

 collection. Two years ago the collection was estimated to contain 

 400,000 specimens. Since then not less than 25,000 specimens have 

 been added to it. It will be several years before an exact statement
