These animals, which in some parts of the seas very likely are to 

 be found as frequent as Tethys in the Mediterranean, belong only

 reduce the number of the mentioned species, which are as follows : — 



1. M. rosea, Rang. 



Mare Gapense. 



2. M. Bangii, B. 



M. rubr. 



3. M. fimbriata, A. et H.''' 



M. Indie. 



4. M. ocellata, B. 



M. Indie.
