probably be classified as belonging to the “upper part 
of the Newer Parian’’ of the Government Geologists. 
These beds are composed, in part, at least, of a dark- 
colored and fine-grained calcareous sandstone containing 
an abundance of small shells. No great extent of these 
beds is exposed ; but near the Rincon, a natural savana 
bordering on Matura Bay, the erosion caused by a small 
stream and the wasting action of the sea have brought 
into view a fossiliferous bed, the organic remains from 
which may probablj" give us an insight into the question 
of the age of the stratum, and may even lead ultimately 
to a knowledge of some of the ph3'sical phenomena which 
succeeded to the deposition of the earlier tertiaries of 
the i.sland. 
2. — Organic Remains. 
The fossils found bj" me in the beds alluded to in the 
foregoing section amount in number to more than ninetj' 
species, and have close relationships with the recent 
fauna, with that of the post-pliocene deposits of the 
Antilles (Barbados, &c.), and with that of the other 
tertiaries of this island. As respects the two former 
cases, I have been able for the most part to compare 
specimens, but in regard to the New Parian fossils I 
have not been able to obtain such full information as is 
desirable. The indications furnished in the Appendix 
to the Geological Report are very meagre ;* and after 
a lengthened but nevertheless somewhat unatisfactory 
examination of the Matura fossils, I have drawn up the 
following list : —
