INTRODUCTION 



This paper is the eighth and final part of a work the intent of which 

 is to describe and illustrate the Foraminifera of the Atlantic Ocean, 

 especially those species which have occurred in the waters adjacent to 

 the shores of the United States, including the whole of the Gulf of 

 Mexico and the Caribbean Sea, that being the area in which most 

 of the work of the vessels of the United States engaged in dredging 

 work has been done. This part includes the families Rotaliidae, 

 Amphisteginidae, Calcarinidae, Cymbaloporettidae, Globorotaliidae, 

 Anomalinidae, Planorbulinidae, Rupertiidae, and Homotremidae. 

 In addition to the collection made by the Bureau of Fisheries steamer 

 Albatross, shallow-water collections from the West Indian region and 

 from along the coast from Florida to Eastport, Me., have been studied.
