30 CONTRIBUTION TO THE PALEONTOLOGY OF TRINIDAD. 



and Turritella mortoni with the characteristic Pernambuco forms Callista mc- 

 graihiana, Chione paraensis, Cucullcea harttii, etc. 



The new species also show strong affinities with basal Eocene (Midwayan) 

 forms from Alabama. 



These relationships not only establish the age of the No. 2 bed at Soldado, but 

 also that of the Pernambuco beds as Midway Eocene. 



Bed No. 6 contains myriads of Foraminifera, especially Orbitoides, echinoids, 

 and one imperfect Ostrea shell, probably of 0. crenulimarginata. 



Bed No. 8 is an indurated rock noticeable from being stained deep red with 

 hematite and greenish and purplish with other forms of iron. 



The following fossils were obtained from bed No. 8:
