Antilles are by no means such a rich field as the region about the © 
Bahama Islands, Cuba, and the Florida Keys, particularly the 
Pourtalés Plateau. Moreover, the amount of dredging in water 
over 100 fathoms deep was much less, and hence the deep-sea nov- 
elties are by no means so conspicuous as those described in the 
various reports on the Bahama Expedition. 
On the other hand, very little work of any kind has been done 
at Barbados and Antigua, and our party brought a quantity of 
material from these islands which will, most of it, add to our 
knowledge of the geographical distribution of marine life. 
The expedition is indebted to numerous friends for aid of 
various sorts, acknowledgment of which will be found in the 
following pages; but the writer deems it proper to mention 
here a number of friends who have rendered particularly val- 
uable service. 
To President Walter A. Jessup of the University of Iowa and 
Dean Carl E. Seashore of the Graduate College we owe our 
thanks for their whole-hearted backing from the very first. Sen- 
ator William S. Kenyon procured credentials from the British 
ambassador and our Secretary of State. To Sir Francis Watts, 
K. C. M. G., Imperial Commissioner of Agriculture for the 
British West Indies, we owe our gratitude for most efficient aid, 
both in connection with the preliminary trip to Barbados under- 
taken by the writer, and in securing the excellent quarters for 
the party at Pelican Island and English Harbor, as well as for 
much valuable advice. Mr. John B. Henderson of Washington, 
D. C., made dredging possible by the use of his launch fully - 
equipped, and the services of his engineer, Captain Greenlaw. 
Dr. Paul Bartsch and Dr. Austin H. Clark of the United States 
National Museum aided us with valuable advice and suggestions. 
The Quebec Steamship Co. was generous im its concessions in 
the matter of transportation for the members of the party and 
our equipment and collections, a most perplexing problem in 
time of war. To the Colonial authorities at Barbados our thanks 
are due for ample quarters and aid of various sorts. His Excel- 
leney, Sir Leslie Probyn, Governor of Barbados, extended valu- 
able courtesies; and his successor, Governor T. C. Fell, did 
everything in his power to make the exposition a success and 
was our steadfast friend throughout. Colonial Secretary Phil-
