ART. 14 FOSSIL AND RECENT BRYOZOA CANU AND BASSLER 51 



Family AETEIDAE Smitt, 1867 



Genus AETEA Lamouroux, 1812

1914. Aetea iruncata Osbukn, The Bryozoa of the Tortugas Islands, Florida. 

 Publication Carnegie Institution, Washington, No. 182, p. 186. 

 (Bibliography.) 



Common in shallow water and down to 5 fathoms, creeping over 

 shells and seaweed (Osburn). A single specimen on shell. 



Harmer ("Siboga," 1926) figures the position of the retracted 

 polypide as well as the jointed filiform, appendages which appear 

 sporadically in this species. He proves also that the ovicells noted 

 in the genus Aetea are not typical and that they are in reality exter- 

 nal ovisacs analogous to those of the Ctenostome genus Nolella. 

 Occurrence. — Albatross Station D. 2405, Gulf of Mexico; 28° 45' N.; 

 85° 02' W.; 30 fms.

 Bay, Panama.

 shell.

Family OPESIULIDAE Jullien, 1888 



Subfamily Onychocellidae Jullien, 1881 



Genus SMITTIPORA Jullien, 1881 



Smitt (1872) gave two figures ^ of his Vincularia ahyssicola of which 

 one (fig. 60, specimen encrusting a Retepora) shows only the zpoecia 

 with ectocyst and the large onychocellaria; in the text he does not 

 describe zooecia without the ectocyst and the form of the opesium. 

 Moreover the zooecia of Velumella americana covered with the ecto- 

 cyst present absolutely and frequently the same aspect with three 

 regular facettes noted by Jullien as characteristic. This peculiarity 



' We are not sure that the two figures given by Smitt (in Floridan Bryozoa) of Vincularia ahyssicola 

 belong to the same species; this description (of the genus Smittipora) refers solely to flg. 60. (Trans- 

 lation after Jullien, Bulletin de la Societe Zoologique de France, vol. 6, 1881, p. 15.)
