The paucity of the fossil representatives of a form now so widely distributed is a striking feature of this list. | What 
fossil forms are known come from Christmas Island (Pleistocene), Java (“ Tertiary”), Sind (Eocene), Persia (Miocene), 
and Egypt (“ Tertiary”), show a fairly wide distribution, and in India a considerable age. These facts would lead us to 
the conelusion that closer research alone is wanting in order to bring an extended fossil Porites fauna to light, at least in 
Tertiarv formations.
