PEOF. P. M. DUNCAN ON THE MADEEPORAEIA 



vigorously growing faunas, are represented at Mergui by varieties 

 which have given me much trouble in their classification. This 

 difficulty was intensified on account of the predominance in the 

 fauna of such large and therefore very variable genera as Mussa, 

 Mceandrina (Coeloria), SympTiyllia, Favia, and Goniastrcea. 



Several species which were described by MM. Milne-Edwards 

 and Jules Hairne, the habitats of which were not known to them, 

 are recognized at Mergui. 



The following is the list of genera and species constituting the 

 fauna.
