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

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

 to the warmer and tropic seas. Continued examination will likely 

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



1. M. rosea, Eang. 



Mare Capense. 



2. M. Bangii, B. 



M. rubr. 



3. M. fimbriata, A. et EL* 



M. Indie. 



4. M. ocellata, B.
