valid. She retains the misleading expression "Oligocene" in- 

 cluding under that head rocks and fossils of miocene as well as of 

 eocene date. 



I had often conjectured that Soldado Rock in the Serpents 

 Mouth (the Southern entrance into the Gulf of Paria might be of 

 eocene age and the conjecture has been verified by Miss Maury, 

 who gives a list of over forty species of molluska from that rock. 



This discovery is of interest from a stratigraphical point of 

 view because it shows that the anticline of eocene rocks running 

 through the southern part of the island from Guayaguayare to 

 Cedros, (Brigit Point, Coral Point) comes out on the southwest- 

 ern point of the island parallel with the Naparima anticline and 

 terminating in the Gulf of Paria by an elevation of hard rock ; 

 Soldado off Cedros being thus analogous to Farallon off Napa- 

 rima. Just as in the case of the Naparima anticline this brings 

 up cretaceous and eocene rocks along its course. I am bound 

 however to record my dissent from Miss Maury's classification of 

 the tertiary rocks of Trinidad. The Manzanilla beds may be 

 lower miocene (Oligocene), but the Cumana beds are upper mio- 

 cene, and the lower beds of the Naparima series (San Fernando 

 beds) are eocene, thus leaving the Caroni series and the oceanic 

 beds of Naparima as miocene, and probably the equivalents of the 

 Bowden beds of Jamaica, and the beds in Haiti, containing Area 

 patricia (see my paper on the Geology of Antigua etc., Journ. 

 Geol. Soc. Vol. 67, November 191 1, Page 699). 



I also record here two collections of tertiary fossils, one 

 made by Mr. C. S. Rogers, Forest Officer, to the Tamana Dis-

trict, and one made by Mr. Cunningham Craig in Venezuela. 

 The first is a most encouraging collection, as it indicates a pal- 

 eontological wealth yet unexplored, and shows what may be ex- 

 pected at the hands of an interested collector. As usual in such 

 collections some of the specimens were not in a condition for 

 identification, but I determined some seven species of which two 

 {Modulus basileus) and Corbula dominicensis) are hitherto unre- 

 corded from Trinidad. The list is as follows : —
