direction. Volume V of the Bulletin series presented the Crus- 

 tacea: Stomatopoda and Brachyura, and Volume VI, the Crus- 

 tacea: Anomura, Macrura, Euphausiacea, Isopoda and Amphip- 

 oda and the Echinodermata : Asteroidea and Echinoidea of this 

 "Alva" World Cruise. 



The itinerary of this circumnavigation of the globe, a cruise 

 of 28,182 miles, which began at Northport, Long Island, New York, 

 thence to the "Alva" Base, Fisher Island, Miami, Florida, was via 

 Cuba, and Jamaica, through the Panama Canal to the Perlas 

 Islands, out to the Galapagos, then the Marquesas, Tamotu and 

 SocietyArchipelagoes, Samoa, Fiji, New Caledonia and Great Palm 

 Island, Australia, then leaving the Pacific, through Torres Straits, 

 to Flores Strait, Sumbawa, Bali, Java, through the Banka and 

 Malacca Straits, Indian Ocean and Arabian Sea to Aden, through 

 the Suez Canal to the Mediterranean Sea, France, Spain, Gibraltar, 

 Morocco, out to the Canaries and Cape Verde Islands, across the 

 Atlantic via Porto Rico, home to Miami. The collections herein 

 discussed were made in the beauteous coral reefs and fascinating 

 tidal zone of the above archipelagoes and localities of the littoral 

 zone of the Indo-Pacific region, that part of the world, oldest in 

 human history, yet still a mystery even to students of science, who 

 have spent their lives in research. The major deep-sea dredgings 

 were made at stations in the Dutch East Indies, off the New 

 Hebrides and off Marquesas Islands, in the Pacific, and off the 

 Canaries, in the Atlantic Ocean and along the continental shelf 

 of the southeastern United States. 



The first reports on the same groups of Invertebrates, obtained 

 during the World Cruise of the yacht "Ara," 1928-1929, is also 

 incorporated in the present Bulletin. The journal of this voyage : 

 "Taking One's Own Ship Around the World, a Journal descriptive 

 of scenes and incidents together with observations from the log 

 book recorded on the Voyage Around the World, October 25, 1928, 

 to May 16, 1929, of the yacht "Ara," commanded by the author, 

 has been delightfully told by Mr. Vanderbilt, in an exquisitely 

 illustrated volume, which includes maps of the voyage and numer- 

 ous color plates of the living specimens, painted by Mr. W. E. 

 Belanske. The "Ara's" route via the Panama Canal traversed 

 some of the most fascinating areas of the Pacific, the Hawaiian, 

 Marshall, Caroline and Philippine Archipelagoes, thence returned 

 home via Cochin China, the Straits Settlements, India, the Suez 

 Canal, Greece, Italy and France, a voyage of 28,738 miles, during 

 which explorations the sea yielded rich harvest of countless rare
