INTRODUCTION 



The present Bulletin, sixth in the scientific series of the Van- 

 derbilt Marine Museum, contains the second report on the Crus- 

 tacea and first report on the Echinodermata secured by Mr. Wil- 

 liam K. Vanderbilt during a world cruise in his yacht "Alva" in 

 1931. The narrative of this voyage, "West Made East With the 

 Loss of a Day," has been entertainingly told by Mr. Vanderbilt 

 in a beautifully illustrated volume with a map of the voyage. The 

 preceding Bulletin contains a report of the Indo-Pacific Crustacea 

 Stomatopoda and Brachyura secured by the "Alva." The present 

 volume consists of two separate reports, the first of which treats 

 of the Crustacea Anomura, Macrura, Euphausiacea, Isopoda, 

 and Amphipoda. This material is from the Indo-Pacific region, 

 except a few hundred specimens from deep-sea dredgings in the 

 eastern Atlantic Ocean, off the Canary Islands. 



The bathymetric occurrence of the species secured ranges 

 from terrestrial, freshwater and littoral to true deep-sea forms, 

 from depths ranging from 140 to 400 fathoms. The collection is 

 extensive and contains many representatives of the littoral fauna 

 from the fascinating coral reefs and tidal zone of the Marquesas 

 Islands, Society Islands, Fiji Archipelago, Samoan Islands, New 

 Caledonia, Bali, Banka Island and the Durian Straits, Dutch 

 East Indies, Penang and Singapore. Some terrestrial Crustacea 

 from the Society Islands were obtained. Members of the fresh- 

 water fauna of the Society Islands, Fiji Islands and Malay Straits 

 were secured. The deep-sea dredgings represented are from sta- 

 tions in the Dutch East Indies ; off the Marquesas Islands, and off
