LETTER OF TRANSMITTAL


HONORABLE R.


L. DOWLING,


Supervisor of Conservation,


SIR:


I have the honor to transmit a report on the Stratigraphy


and Micropaleontology of Two Deep


Wells in Florida by Dr.


Storrs Cole of the Ohio State University,
lished as Geological Bulletin No. 16.


Columbus,


to be pub-


the drilling of


deep


wells in Florida much information


of permanent value is obtained and this is especially true when


samples


the cuttings


and


cores


material


penetrated


are saved and studied.


The two wells here reported upon have


yielded fundamental data about the character, thickness and age
of the deposits encountered and will add to our knowledge of the
structure and stratigraphy of that portion of Florida in which
they are located.

I want to take this opportunity of expressing my appreci-
ation of the interest you have shown in the work of the Geological
Department and the support you have so generously given it.

Very respectfully,


HERMAN


GUNTER,


Assistant Supervisor,
State Board of Conservation,

of Lepidocyclina parvula which has been considered to date to
be confined to the middle Oligocene.
The information obtained from this well in conjunction with
the available known ranges of the larger foraminifera suggests
that the Meson is older than the Heterostegina-Miogypsina zone.
The writer believes that the last sample of the well represents


a formation


which


will


eventually


found


the equivalent of the Meson formation.
The writer20 described a fauna of larger foraminifera from


near Duncan Church


, Washington County, Florida, and assigned


the beds which contained this fauna to the Glendon.


Cooke, in


a personal communication to the writer, states that at present


he correlates these beds with the Suwannee limestone.


As this


fauna contains Lepidocyclina super which is characteristic of


the Byram marl,


Cooke


is undoubtedly


correct.


Although


present well was studied in great detail, none of the species re-
ported from near Duncan Church were found, except L. undosa

The washed portion contained a few calcareous fora-

A core taken at 1761-68 feet, however, contained an excel-

The lithologic and


paleontologic evidence from these cores indicates that the base


of the Nanafalia formation and the


top of the Midway

between 1679 feet and

Inasmuch as the driller's

Subfamily


Miogypsininae


Vaughan


Barker and Grimsdale" have recently demonstrated the pres-


ence of a canal-system in


Miogypsina.


certain representatives of the genus


It is obvious that such a discovery automatically


removes this group from the Orbitoididae.


Barker and Grims-


dale present evidence to show that the subfamily Miogypsininae
should be transferred to the family Rotaliidae.
It seems more logical to the writer to place this subfamily


under the family Carmerinidae.


This conclusion is based


on a


study of the relative forms of the tests.
Miogypsina is composed of a definite equatorial layer with
the lateral chambers and pillars developed on either side of the


equatorial layer.


In general plan, the test of Miogypsina is not


essentially


different from that of Spiroclypeus.

Miogypsznoides resembles
