Previous to Smitt's work Pourtales^ listed and described as new 

 seven species of bryozoa two of which have been found to be syno- 

 nyms. Levinsen, in his " Morphologic and Systematic Studies on the 

 Cheilostomatous Bryozoa " (1909), records six species from the Florida 

 and West Indian region, two of them new. Since Osburn's paper in 

 1914 no important work upon the recent bryozoa of the Gulf has 

 been issued, but with the publication of our work* on the Early 

 Tertiary and Later Tertiary and Quaternary Bryozoa of the Atlantic 

 and Gulf Coastal Plains of the United States containing numerous 

 fossil faunas of Gulf origin the study of the recent bryozoa from this 

 region assumes new interest. 



More than 40 stations of the Albatross explorations of 1883-1888 

 have been found to contain bryozoa, some of them in great richness. 

 Most of these stations are located in the Gulf of Mexico, including 

 the Florida Straits and the Straits of Yucatan, although two (D. 

 2117, D. 2136) from the Caribbean Sea and two (D. 2672, D. 2415) 

 east of Georgia and Florida have been included. Few species 

 occurred at these four stations so that the larger faunas have all 

 been derived from the Gulf of Mexico. We also have been able to 

 include studies on faunas from the vicinity of Miami, Fla., collected 

 by the late John B. Henderson. For convenience of reference, the 

 Gulf Stations can be classified as follows: 



D. 2354, 2362, 2363, 2365, Straits of Yucatan; D. 2152-2343, Gulf 

 of Mexico, north of Habana, Cuba; Fowey Light and D. 2639, 2640, 

 2647, Straits of Florida; D. 2411, 2413, 2414, 2404, 2405, 2407, 2373, 

 2387-2392, Cedar Keys, Egmont Key, and Tortugas, Gulf off west 

 coast of Florida. 



As in the past, we are under obligations to Mr. F. Julius Fohs, of 

 New York City, who has shown his appreciation of our studies on 

 microorganisms by generous financial assistance in the preparation 

 of this paper. 



The bryozoa described by Smitt and by Osburn are cited in the 

 following two lists while those noted in the present paper are given 

 on succeeding pages. Species in the first two lists marked with an 

 asterisk are discussed in this work. The plate and figures cited in 

 the first list refer to Smitt's work while the depth is registered under 

 Osburn's list.
