56 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 66 



1 91 5, in the Danish West Indies, under the auspices of the Carnegie 

 Institution of Washington, D. C, securing collections of corals and 

 other marine invertebrates. 



The collecting was done in the open water, bays, and channels at 

 St. Thomas, St. John, and St. James. The deeper waters were 

 explored by means of dredging from a motor boat, while native 

 divers, working from the heavy West Indian row boats, were used 

 for collecting in the shallow waters. In addition to this, much shore

collecting was done. Owing to the very strong and constant trade 

 wand, work on the exposed reefs was in many cases made impossible 

 by the heavy surf. Collecting in the protected bays, however, was 

 most successful, as a great variety of bottom was to be found in 

 many of them. 



While the chief aim of the expedition was to secure as complete 

 a representation of the coral fauna as possible — and this aim met 

 with considerable success — fine collections of other marine inverte- 

 brates were also obtained, including protozoa, sponges, hydroids, 

 medusae, alcyonarians, anemones, bryozoans, starfish, sea urchins.
