valid. She retains the misleading expre.ssion “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 gi\-es a list of over forty species of molluska from that rock. 
This di.scovery is of interest from a stratigraphical point of 
view becau.se it shows that the anticline of eocene rocks running 
through the southern part of the island from Guaj'aguayare to 
Cedros, (Brigit Point, Coral Point) comes out on the southwest- 
ern point of the island parallel with the Xaparima anticline and 
terminating in the Gulf of Paria b3^ an elevation of hard rock ; 
Soldado off Cedros being thus analogous to Farallon off Napa- 
rima. Just as in the ca.se of the Naparima anticline this brings 
up cretaceous and eocene rocks along its course. I am bound 
however to record 1113'^ dis.sent from Miss Maur3’’s classification of 
the tertiar3' rocks of Trinidad. The Manzanilla beds ma3' be 
low’er 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 Caroui series and the oceanic 
beds of Naparima as miocene, and probabh'the equivalents of the 
Bowden beds of Jamaica, and the beds in Haiti, containing Area 
patricia (see 1113^ paper on the Geolog3’ of Antigua etc., Jouru. 
Geol. Soc. Vol. 67, November 1911, Page 699). 
I also record here two collections of tertiary fossils, one 
made by Mr. C. S. Rogers, Forest Officer, to the Tamana Dis- 
Page 4 
trict, and one made b3' Mr. Cunningham Craig in \'enezuela. 
The fir.st is a most encouraging collection, as it indicates a pal- 
eontological wealth yet unexplored, and shows what ma3' 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 
{Moduhis basileus) and Corbula do?>nnicensis) are hitherto unre- 
corded from Trinidad. The list is as follows : —
