Coral Reefs. 
Agassis (1) describes the Coral Reefs of the Bermudas. 
Mill (151) discusses Basset Smith’s studies on the Macclesfield Bank. 
Gregory (83) arrives at the following conclusions with regard to the 
affinities of the fossil corals of Barbados:- — 
1. Those of the raised reefs of Barbados give no trace of the influ- 
ence of- admixture with Pacific types. 
2. The fauna is an offshoot of that of the Miocene of the Mediter- 
ranean basin. 
3. Its nearest living ally is, therefore, that of the Red Sea and 
Indian Ocean. 
4. The migration of this fauna westward across the Tropical 
Atlantic supports the theory of the existence of a shallow 
water ridge. [See also Judd (122), “Challenger” corals;
