Boone, Crustacea, Cruises of "Eagle" and "Ara," 1921-28 13 



ecology of the sea is acknowledged, yet little work has been done in 

 America on this subject. There is great need for a thorough mono- 

 graphic report of American Crustacea. 



Acknowledgments. 

 As during the preparation of the preceding volume, Mr. Vanderbilt 

 has generously placed unexcelled facilities at my disposal throughout 

 the present investigation. I have also enjoyed full privileges of 

 research in the American Museum of Natural History and am espe- 

 cially indebted to Dr. R. W. Miner, curator of the Department of 

 Lower Invertebrates, and to Miss Hazel Gay and Miss Margaret Tit- 

 comb of the Library. The colleagues and institutions whose friendly 

 cooperation contributed to the success of the first volume have con- 

 tinued their kindness during this report. The line drawings of the 

 present volume were made by Mrs. Helen Ziska, who also retouched 

 photographic illustrations which were made, also under my direction, 

 by IVL'. Julius Kirschner of the photographic laboratory of the Ameri- 

 can Museum of Natural History. The color plates referred to were 

 prepared by Mr. W. E. Belanske, under Mr. Vanderbilt 's direction.
