NO. 5 OSBURN : BRYOZOA 23 



Bugula flabellata (J. V. Thompson), 1847 



Smitt 1872: 18. Osburn 1914: 17; 1940:391. 



Widely distributed in temperate seas; on the Atlantic coast from 

 Maine to Brazil. Smitt listed it from Florida; Osburn found it at the 

 Tortugas Islands, Florida, and Porto Rico. 



Distribution. — Station A32-39, 3 miles N of Coche Island, 19 to 

 ZZ fms. 



Bugula turrita (Desor), 1848 



Osburn 1912:225. Marcus 1937:68. 



An abundant species along the North Atlantic coast from Massa- 

 chusetts to North Carolina and Marcus found it at numerous places in 

 Santos Bay, Brazil. Strangely enough, it did not appear in Osburn's 

 studies of Porto Rican Bryozoa (1940), nor did Canu and Bassler 

 report it from the Gulf of Mexico (1928). More recently the writer 

 has received a specimen from southern Florida. Its appearance in the 

 southern Caribbean is not remarkable, but evidently this species does not 

 thrive in tropical waters as it does in more temperate areas. 



Distribution. — Station A30-39, Cubagua Island, shore, several young 

 colonies attached to a shell. 



Bugula johnstonae (Gray), 1843 



Smitt 1872:17 (Halophila johnstoniae). Canu and Bassler 1928:42 

 (Halophila). 



Widely distributed in Australian and East Indian waters. Smitt 

 recorded it from Florida and Canu and Bassler list it from one station 

 in the Gulf of Mexico (Albatross station 2405J. Osburn did not find it 

 at Porto Rico. It is a coarse and striking species of such a nature that it 

 could not be readily overlooked. The present material is abundant and 

 there are occasional ovicells. It has usually been reported without ovi- 

 cells and Levinsen (1909:97) definitely indicates that the genus Halo- 

 phila is without ooecia. Harmer (1926:448) found them in specimens 

 from Celebes and Canu and Bassler found them in their Florida material. 



Distribution. — Stations A18-39 and At505, San Nicolaas Bay, 

 Aruba Island, 22 to 24 fms.
