BRYOZOA OF THE UNITED STATES NAVY'S 1947-1948 

 ANTARCTIC EXPEDITION, I-IV ' 



By Mary D. Rogick^ 

 Introduction 



The U. S. Navy's 1947-48 Antarctic Expedition brought back a 

 sizable collection of Bryozoa that was turned over to the U. S. National 

 Museum. The specimens to be discussed in these and subsequent 

 papers of the Antarctic series are from this collection, which consists of 

 one endoproct species and more than 100 ectoproct species, some of 

 which are new. 



Because of the large amount of interesting material in the collection 

 it was found necessary to break up the work into a series of papers, of 

 which the first four are contained here: I. Barentsia discreta; II, 

 Family Cellariidae; III. Family Sclerodomidae; IV. Families Um- 

 bonulidae and Smittinidae. 



The writer expresses deepest appreciation to the U. S. National 

 Museum (USNM) for the loan of the collection and to the National 

 Science Foundation for the research grant that so greatly aided these 



' I, Barentsia discreta, pages 224-227 and plates 1, 2; II, Family Cellariidae, pages 228-252 and plates 3-11;
