POLYPI, 89 
an animal much resembling an Actinia, with a large oval oral-aperture 
surrounded by numerous, very large, transparent tuberculated rays. The 
other species upon which LAMARCK has founded this genus are only known 
in the fossil state. It was thought that they were not affixed, and con- 
sequently they were referred to this family ; the discovery, however, of the 
voyagers quoted above, shews that the species now living far rather belongs 
to the family of the Ocellina, and probably ought to be joined to Mono- 
myces EHRENB. It may be suspected, perhaps, from STuTcHBURY’s 
observations, that here younger forms of Fungia have crept in. 
To Turbinalia the genus Diploctenium Goupruss, Flabellum LESSON 
may be added. See Flabellum pavoninum Less. Illustrations de Zool. 
Pl. xiv. 
Note. The genus Lithactinia Lusson related to the /ungice, might 
perhaps from recent investigations be established with propriety.
