NO. 5 OSBURN: BRYOZOA 29 



Schizoporella floridana Osburn, 1914 



Osburn 1914:205; 1927:126 (Schizopodrella) ; 1940:422. Canu and 

 Bassler 1923:106 (Schizopodrella floridana) ; 1928:93 (Schizopodrella). 



This species has been recorded by Osburn from the Tortugas Islands, 

 Florida, Curagao and Porto Rico; by Canu and Bassler from east of 

 Yucatan, Gulf of Mexico, and from the Miocene of North Carolina and 

 Florida. 



Distribution. — Stations A14-39, 2 miles SW of Cape la Vela, Colom- 

 bia at 21 to 22 fms, and At526, Tortuga Island at 41 fms. 



Schizoporella (Stephanosella) biaperta(Michelin), 1845 



Smitt 1873:46 (Hippothoa). Robertson 1908:287. Osburn 1912:237. 

 Canu and Bassler 1923 (Stephanosella). 



This is practically a cosmopolitan species, abundant from Florida 

 northward, and it is difficult to understand why it has not been reported 

 south of Florida. In all of the work done in this general region by Osburn 

 and Canu and Bassler this species has not been noted and the only 

 reference is that of Smitt for "Florida seas." Marcus has not reported 

 it for Brazil. On the west coast it is an abundant species from British 

 Columbia to the Galapagos Islands. Canu and Bassler list it from numer- 

 ous localities in the American Miocene and Pleistocene. It is such a char- 

 acteristic form that it could hardly fail to be identified, so the conclusion 

 seems inescapable that S. hiaperta is rare or wanting from Florida south- 

 ward. 



Small colonies were taken at the stations mentioned below, but these 

 showed none of the luxuriance of growth that is common to the species. 



Distribution. — Stations A14-39, 2 miles SW of Cape la Vela, Colom- 

 bia at 21 to 22 fms and A32-39, 3 miles N of Coche Island, Venezuela at 

 19 to 33 fms.
