A Coral Reef in the New Hebrides


  • *Communicated by Prof. E. S. Goodeich, F.R.S., F.Z.S.


On the north-east coast of Gaua, in the New Hebrides, there is a fringing reef about half-a-mile wide. Coral growth is most active near the shore, the dominant coral in this zone being Montipora ramosa. Outside the double boulder zone coral growth is not very active, and Lithothamnium does not flourish as it does in so many reefs.

It is suggested that a fringing coral-reef not only grows outwards on its own talus bed, but also grows inwards to form a thin layer lying on a flat shallow platform produced by the erosion of the coast.
