NOTES ON SHRIMPS FROM THE MARSHALL ISLANDS 



By Fenner a. Chace, Jr. 



The collections on which the following notes are based were made 

 during biological surveys of the northern Marshall Atolls of Eniwetok, 

 Bikini, Rongelap, and Rongerik in 1946 and 1947, under the sponsor- 

 ship of the U. S. Department of the Navy. Only the decapod shrimps 

 of the families Penaeidae, Sergestidae, Pasiphaeidae, Processidae, 

 Thalassocaridae, and the genera Automate and Aihanas of the Alphei- 

 dae are included here. Pressure of other work has precluded the 

 possibility of completing the study of the remaining shrimps of these 

 collections in a reasonable length of time. It is hoped that Dr. A. H. 

 Banner of the University of Hawaii will be able to work up the 

 remaining aipheid shrimps; and Dr. L. B. Holthuis of the Rijks- 

 museum van Natuurlijke Historic, Leiden, The Netherlands, 

 has agreed to include those of the families Hippolytidae, Rhyncho- 

 cinetidae, Palaemonidae, Gnathophyllidae, and Stenopodidae in a 

 forthcoming report on macrurous Crustacea collected by recent 

 expeditions to several of the Pacific island groups.
