REMARKS ON THE GEOLOGICAL POSITION OF THE 
POL YC VS TINA BEDS OE SO UTH NA PA RIM A . ^ 
Published in “The Agricultural Record’’, vol. 3, Aug.- 
Dec. , 1890, pp. 178-180. 
The subject of the Polycystina beds of South Naparima appears 
to have attracted some little notice of late, for we find com-, 
munications thereon in the pages of the Agricultural Record. ^ 
I do not pretend to be well up in all the points of discussion. The 
few words I hav'e to say will be chief! 3^ directed to the elucidation of 1 
the geological position of the pol3'C3'stina deposits. j 
I have not been able to find the first mention of the occurrence 1 
of radiolaria in Trinidad rocks. I am told that a paper on the sub- 
ject appeared in one of the English scientific journals, but I have j 
never been able to find it. The references to the subject in the 1 
Geological Report on Trinidad are rather scant3'. 
In a paper published in the 22nd volume of the Journal of the 
Geological Societ3T 1 866, p. 571) I gave a diagram of the coast .sec- | 
tion at Sanfernando. This sketch was ver3' imperfect on account of j 
the disintegrated materials from the upper part of the cliff having 
obscured the nature and relations of the beds. Nevertheless, in 
main features the diagram fairh' represents the position and suc- 
ces-sion of the rocks. I was wrong, however, in supposing certain 
of these beds to be unfossiliferous. I subsequentE’ discovered that 
the3^ contained abundant foraminifera, and in 1872 I published an 
account of of the discover3' with a preliminar3' list of the foramin- 
ifera. The3' were as follows : —
