AND FLORIDA. 



(For the position of the stations, see figure 9, page 339 the maximum depths at a station under 1,000 meters 

 indicates bottom; if the maximum is over 1,000 meters, bottom may not have been touched.) 



The data for the following table were obtained during the cruise of the 

 U. S. Coast and Geodetic Survey Steamer Bache, while under the command of 

 Capt. C. C. Yates, in February and March, 1914; the tabulations were 

 made by Mr. W. W. Welsh, naturalist of the ship; and Dr. H. F. Moore, 

 of the U. S. Bureau of Fisheries, has furnished the copy for publication in 

 this paper. The bearing of the information on the bathymetric distribution 

 of reef corals is discussed on pages 321, 322.
