do not correspond. The name had best be dropped. 

 Semiescharipora D'Orbigny, 1852. Bry. Cret., p. 479. Lang, 1917 has chosen 



8. complanata D'Orbigny, 1852 p. 484, pi. 718, figs. 17-20, as the ty^pe. 



This is an uncertain species and the generic name should be dropped.

bombycina Solander, 1787, not recognized. The second species (S. frondi- 



culosa) has never been figured. The third is Flustra carbasea Ellis and 



Solander, 1786. Genus may therefore be considered a synonym of 



Carbasea.
