iln 1848 Gray (Proc. Zool. Soc, London, Appendix, 1848, and List of British Animals in the collec- 

 tion of the British Museum, 1848, pp. 109, 146) proposed the generic term Callopora for a single species, 

 the Flustra lineata of Linnajus, but the term failed to gain acceptance, and the species lineata is now 

 considered to be a Membranipora. As Callopora Hall has become deeply engrafted into literature, it 

 seems undesirable under the circumstances to replace it by a new name.
