INTRODUCTION. 



The present volume is the second of a series dealing with the 

 Foraminifera of the North Pacific Ocean. It contains the Foramini- 

 fera included in the family Textulariidse. The first part, issued in 1910, 

 included the families Astrorhizidse and Lituolidse. The third part, on 

 which work is now actively being done, will be devoted to the Lagenida-, 

 and further volumes will take up the remaining families of the 

 Foraminifera as they are represented in the North Pacific.
