REPORT OF THE STATE PALEONTOLOGIST 1903

To the Regents of the University of the State of New York
I have the honor to report herewith on the work of this de-

partment during the year commencing Oct. I, 1902.

Operations in the field 1902-3

Stratigraphic survey of the Schoharie region. ‘The earliest strati-
graphic determinations in New York based on a careful collation
of paleontologic evidence were made in the valley of the Scho-
harie creek and the region immediately about Schoharie Court
House by two generations of the Gebhard family. The forma-
tions along the creek south of Esperance are exposed to extra-
ordinary advantage and their richness in organic remains, com-
bined with the eager zeal for the study of nature possessed by the
Gebhards, father and son, led to the appointment of John Gebhard jr
as assistant on the original geological survey because of his familiar-
ity with the geology and the contents of the rocks in this portion
of the first district, then assigned to the charge of Lieutenant Mather.
The outcome of this early study of the rocks in the Schoharie valley
has made itself effective in the paleontology of New York in many
ways. When Professor Hall came to study the paleontology of the
formations there represented, he found it imperative for him to rely
chiefly for his subject-matter on the extraordinarily fine and com-
plete Gebhard collections. The account given by him of the species
of the Lower Helderberg and Oriskany faunas, which constitutes
volume 3 of the Palaeontology of New York, was so largely derived
from these collections that it was deemed wise by the museum to

4 NEW YORK STATE MUSEUM

subsequently acquire one of them, and on a later occasion still another

was secured from the same source. Because of these facts the Scho-

harie section has become a basis of reference in studying these

faunas, and for 50 years past it has been a region freely visited by
students of geology; and yet during all this time no geologic map
of the area has been published except on a very small scale in con-
junction with and as a part of the maps of the State as a whole. To
meet a definite want on the part of students, and for the more detailed
exposition of the geology of that region a map has been com-
pleted during the present season on the quadrangle scale which
covers the area from Middleburg northward to the south line of
Montgomery county. The work has been carried out by Prof. A.
W. Grabau, who has previously labored with much credit on similar
problems, and his map and report thereupon are presented in the
following pages.

Structure of the disturbed fossiliferous rocks in the cement district
about Rondout. ‘The lucid and very interesting exposition of the
geology of Becraft mountain which was given in my last report
has led to a consideration of the rather more complicated region
of rocks of like age on the opposite or west side of the Hudson

river. Becraft mountain in Columbia county is the remotest

outlier of the series of rock beds which so extensively enter into |

the composition of the Helderberg mountains of Albany county.
At Kingston, Hudson and eastward these rocks were caught in the
Appalachian folding, and subsequent erosion of these folds has iso-
lated the area at Becraft mountain entirely from the parent mass.
At Rondout and vicinity the rocks have been left in continuity,
but it has long been recognized that they are exposed under
much perplexity of form, due to the folding and displacement
of the beds. The structural problems presented theres have
never been understood and as long as geologic work has been car-
ried on in this State the situation in this region has been
somewhat timorously approached. These problems seemed to afford
features of much interest connected with the tectonics of the
region and the mode of the Appalachian disturbances, and the
fact was recognized that a solution would probably not be found

without the aid of the evidence derived from studying the fossils.

I therefore asked Mr Gilbert van Ingen, who at that time was

officially connected with this department and who had many
years’ familiarity with the region, to undertake the attack on
the difficult situation there presented. Mr van Ingen with the
assistance and cooperation of Mr P. Edwin Clark, for many

years superintendent of the Newark Lime & Cement Co. at

-Rondout and mining engineer of long experience, has given the

subject very detailed examination and careful study. His results
were presented in the report of last year and will be found to
afford a well illustrated exposition of the obscure and complicated
structure of the region.

Traverses of the Catskill mountains and collections of the fauna
of the Port Ewen beds. During a part of the season Mr George
H. Chadwick has been engaged in reviewing the section of the

Catskill mountains in Greene county, in the hope of ascertaining

some new clues to the nature of the life forms in the higher

strata. Subsequently he was occupied in collecting as freely as

practicable from the limestone and shale beds which constitute
the Port Ewen (formerly termed the Kingston) beds and best
exposed in the vicinity of Rondout and Kingston. This forma-
tion is that at the top of the series originally termed the Helder-
berg and subsequently Lower Helderberg, and is a sedimentary
facies reproducing that of the Catskill shaly limestone below,
otherwise known as the New Scotland beds. The fauna of these
upper beds has not been carefully analyzed, though there has
been a well grounded belief that its affinities were with the later
or Oriskany fauna rather than with that of the Helderbergian
beneath.

Distribution of the Cobleskill limestone. Reference was made
in the last report to the study of this formation, the importance
of which as an element in the New York series had not hereto-
fore been recognized. Mr C. A. Hartnagel has continued and
concluded this study and has traced the formation from Port
Jervis at the south, northward through Orange and Ulster

counties and from Schoharie county westward through Otsego,

6 NEW YORK STATE MUSEUM

Herkimer and Onondaga counties and on to Erie county. The
outcome of Mr Hartnagel’s work has been to demonstrate the
continuity of this apparently feeble element in the rock succes-

sion and to indicate its significance as a closing phase of the

Siluric formation and fauna in the State of New York. Origin-
ally brought into the nomenclature of the science as the Coral-
line limestone and believed to have a purely local significance in
the Helderberg region and the adjoining districts westward, it
is now found to have been notably underestimated in its con-
tinuity and extent.
Paleontology and stratigraphy of the slate belt of eastern New
York. Mr Ruedemann, who has been concerned with the prob-
lems presented by the obscure and somewhat complicated struc-
ture of this region, has continued his investigations, giving
special attention to the region about Granville, for the purpose

of reexamining the localities from which Messrs Walcott, Dale _

and Prindle obtained paleontologic evidence during their study
of the region. The exploitation of the graptolite faunas of these
rocks, which here, as in other parts of the world, have been
found of material importance for the correlation of these with
distant formations, has led to the restudy of the structure of Mt
Moreno near Hudson which, previously known by an excellent
exposure of the Normanskill graptolite shale, has become still
more interesting by the discovery of the uppermost zone of the
Phyllograptus shale before known in New York only from the
Deep kill section of Rensselaer county. All the data now obtain-
able bearing on the composition of these graptolite zones and
the correlation of these geologic formations with those of remote
regions of the world have been brought together in the form
of a monograph of the graptolites of the older New York rocks,
and this is now in press.

Beekmantown and Chazy formations of the Lake Champlain basin.
In continuing an examination of the lower faunas of this region,
which has been carried on during several seasons, the assistant

paleontologist spent the greater part of the field season. The —

real import of these faunas in the paleontology of New York

was not brought out in the early surveys of the region, and we owe
our present knowledge of them, specially of the former, chiefly
to the labors of Professors Brainerd and Seely of Middlebury
Vt., whose investigations however were chiefly confined to Ver-
mont, and to Professor Whitfield, who has described most of
the fauna as now known. The congeries of life forms herein
is surprisingly profuse and embodies a multitude of novel
species of notable interest. It was deemed necessary for a suc-
cessful exploitation of these two formations to determine the
detailed succession of the faunas bed by bed at the typical ex-
posures, Beekmantown and Chazy. Thereafter the exposures on
Valcour island, which are of unusual interest, were examined
in detail, specially the cliffs along the west and south shores.
A large amount of material was acquired by this work, and some
account of the new forms obtained is appended to this report.
A fuller revision and description of the entire faunas of the Beek-
mantown and Chazy formations will be undertaken when the
other exposures in this region have been carefully examined.
Correlation of the New York Devonic with that of Gaspé, Canada.
In a previous report record was made of the effort to elucidate
the composition and origin of the early Devonic faunas of New
York by a comparative study of the Devonic areas in the eastern
counties of the Province of Quebec. Here the faunas attained
unexampled profusion of development and-it was shown as a
result of a brief collecting trip to Grande Gréve, Quebec and Dal-
housie N. B., by the paleontologist in 1900, that a close examina-
tion of the fauna of the Grande Greve limestones would bring
out many facts helpful to the problems before us in New York.
The Grande Greve limestones exposed on the north shore of
Gaspé bay are repeated only at Percé, on the westernmost coast
of Gaspé county, south of Gaspé bay, and this spot was visited
during the past summer. The environs of the fishing village of
Percé are of extraordinary interest to the student of the older
rocks. The limestone series has been greatly disturbed here, the
faulting having brought up sections of those rocks in different
places and at differing angles. Only the Percé rock, a stupen-

8 NEW YORK STATE MUSEUM

dous detached cliff cut off by the action of the sea from the
mainland, satisfactorily represents that portion of the limestone

series to which in northern Gaspé the term Grande Greve lime-

stones has been applied. This mass of reddish and yellowish

limestones rising from the sea with sheer walls and vertical
strata is profuse in interesting fossils, of which a large number

were obtained, together with interesting series from the lime-

stone exposures of earlier age. It is safe to say that the col-—

lections in the possession of the State Museum, both of the fossils
at Percé and of those at Gtande Gréve, are without equally sims
subsequent part of this report I have added a brief preliminary
account of the stratigraphy and paleontology of Perce.

Areal survey of the Elmira, Watkins, Ithaca and Waverly quad-
rangles. As reported last year operations were carried on during
the season of 1902 in cooperation with the United States Geo-
logical Survey in an areal survey of the Elmira quadrangle.
Under this arrangement as carried into practice in the Olean
and Salamanca quadrangles stratigraphers were furnished for the
field work from the corps of the survey and their expenses were
met from the appropriations of this department, and we under-
took at the same time to acquire the necessary paleontologic
collections for proving the stratigraphic work. The strati-
graphic work on the Olean and Salamanca sheets was chiefly
done by Prof. L. C. Glenn, a skilful and exact observer, and the
paleontologic collections therein were acquired and largely de-
termined by Mr Charles Butts, representing this department.
In my judgment the work of these two men was carefully exe-
cuted, though leading to some divergence of conclusion with
regard to classification.

The basis of this cooperation conceded to us the use for our
publications of such maps and reports as the geologists of the
United States Geological Survey should prepare, but we have
found it impracticable to avail ourselves of this provision, first,
for the reason that the scale of the United States Geological
Survey folio maps is one we regard unsuited to our practice and,

again, that the execution of these maps and reports was to

REPORT OF THE STATE PALEONTOLOGIST 1903 9g

be so long deferred as to qualify their usefulness to us. We
were therefore compelled to incur the unexpected expense of
engraving these maps on the quadrangle scale and to have a
special report prepared to accompany them. In the work on
the Elmira quadrangle, it was my desire and plan to cover con-
tinuously therefrom in this areal survey the adjoining territory
to the north and east, as therein were involved some interesting
questions of classification of the rocks and faunas concerning
which we had been diligently acquiring data for many years.
The outcome of that work in 1902 was disappointing. No data
were acquired by the stratigraphers on which even a preliminary
areal map could be constructed and I was unable that year to
send our more experienced workers into this rather difficult field
to check up the determinations of the stratigraphers. In con-
sequence therefore we decided to hereafter execute such work
ourselves. It is hardly to be expected that geologists whose ex-
perience has been restricted to broad reconnaissance in imperfectly
known regions can enter anywhere in this State where the rocks
have been continuously studied for nearly 70 years and achieve the
results required in New York. It is not our desire to encourage
such enterprises. We have therefore made a new start this season
beginning with the Elmira quadrangle and extending the work in
detail north to the Watkins quadrangle. The undertaking has been
essentially in charge of D. D. Luther, whose skill in the careful
stratigraphic determination of the older rocks in New York is in my
judgment not to be surpassed. This work has occupied essentially
all of Mr Luther’s time, with that of H. S. Mattimore, during the
field season of 1903, with the result that the Elmira and Watkins
maps are essentially complete and the Ithaca and Waverly sheets

fairly covered.

REPORT OF THE STATE PALEONTOLOGIST I903 II

Bulletin 65. Type Specimens of Paleozoic Fossils in the New
York State Museum. This catalogue, which has been an arduous
compilation and long in press, is a record of the possessions of the
museum in this important class of objects. Type specimens of natural
objects, that is the actual material on which published descriptive
accounts and discussions have been based, constitute the unique treas-
ures of a museum. Such objects once lost or destroyed, replacement
is impossible. Howsoever imperfect or fragmentary the type or
original specimen may be, of however superior quality some other
example of the same creature, the sécond can not serve to scientific
students the function of the first. The type specimen is the basis of
comparison and reference for all time.

The publication of the Palaeontology of New York and the exten-
sive list of papers accessory and supplementary thereto have given
birth to a very large number of type specimens from the paleozoic
strata of America. Some part of these, specially that utilized in the
early volumes of the paleontologic reports, was the personal property
of the author of those reports and passed from his hands to the
possession of the American Museum of Natural History in the city
of New York. Till the preparation of this catalogue was begun, no
serious effort to bring together the type specimens in the State Mu-
seum of these and other descriptions into one place or record was
ever carried to completion. Some years ago the writer undertook
the work of publishing lists, believed to be complete at the time, of
certain of the organic groups, namely the Crustacea, Vermes and
Cephalopoda ;! but a revision of these lists has shown considerable
omissions, due somewhat to normal growth as investigations have
progressed but more to the fact that these types have been scattered
all through the collections of the museum both in the State Hall and
in Geological Hall. It has been an arduous task to search out and
bring together these specimens, which during the past half century
have become so widely and carelessly diffused, but their number is
noteworthy, and the importance of this record justifies the labor put

merit.

This catalogue is arranged as follows:
The general classification is biologic and follows the broadest sub-

divisions. Each entry represents a single specimen and is .accom-

panied by two numbers, the first serial, the second fractional and —

corresponding to the number borne by the specimen. In this frac-
tional number the numerator carries the number assigned to the
major division, the genus and the species, while the denominator
indicates the number of the specimen of the species. Thus, the
sponge Dictyospongia’ sceptrum Hall (Sp)) carries ate
number 748+. 2000 is the number assigned to the Spongiae, 2260
that assigned to the genus Dictyospongia, 2264 the number for D.
sceptrum, the fourth species of that genus, and 7%** the num-
ber for the second specimen of this species. In the scheme of num-

bering the following is the allotment made for the major biologic

divisions.
Plantae 100 Lamellibranchiata 9 000
‘
Protozoa 1000 Gastropoda 10 00O
Spongiae 2000 Pteropoda II OOO
Cnidaria 3.000 Cephalopoda I2 000
Echinodermata 4 000 j 13 000
Crustacea
Vermes 5 000 | 14 000
Bryozoa_ . 6000 Tracheata 15 000
; 006 Pisces 16 000
Brachiopoda Z
8 000

For ease of use it has been the purpose to keep these divisions as
broad as practicable, in order to avoid duplicating too often the alpha-
betic arrangement of the species and to maintain the elasticity of the
scheme in the incorporation of future additions. The work does not
purport to be one on taxonomy, but aims to present the arrangement
in the simplest form. During the progress of the printing of the cata-
logue, a period of 18 months, the continuous publication of paleon-
tologic researches and acquisitions to the collections by gift and pur-
chase have notably increased the number of type specimens and these

have been added in a supplementary list brought up to February
1903.

REPORT OF THE STATE PALEONTOLOGIST I903 1s

While the main part of the book is devoted to the biologic arrange-

‘ment of the type material, a second part gives a concise relisting of

the species in their stratigraphic arrangement.

A chief purpose of this record is to make available to students the
card catalogue of these types now in the possession of the museum.
At the same time it serves to indicate the wealth of the museum in
these important elements, of which upward of 5000 are here listed, a
number which exceeds all type specimens of paleozoic organisms
from the New York rocks in the possession of all other collections
taken together.

This list of type specimens was complete up to the time of going
to press, but the progress in our work since then has already necessi-
tated the preparation of a second supplementary list including the
increase to the present time, and such list is submitted as a part of
this report. These accessions to our collection of type specimens now
raise the total to 5700.

Bulletin 66. The Ellis Index to Publications of the New York
State Natural History Survey and New York State Museum. This
admirable compilation is entitled to special notice here, because of
its exhaustive treatment of the paleontologic publications and its
index to descriptions of genera and species of fossils. The latter
part of the book covering 127 pages was prepared in this office. It
has reference solely to dates of publication and undertakes no notice
of subsequent revision of generic or specific names. It contains up-
ward of 5000 references.

Bulletin 69. Report of the State Paleontologist for 1902. This
bulletin contains the following scientific papers:

The labor necessary to preparing the publications above listed has
been an essential part of the office duties of all members of the staff.
We look on the outcome of the year in this regard as fruitful and
satisfactory but as in nowise lessening the sum of the problems still
before us.

I have added to this report a detailed discussion of the Lower
Devonic rock section at Port Jervis prepared by Prof. H. W. Shimer
of the Massachusetts Institute of Technology. The paper has
features of special interest in the analysis of the faunas of the Port

Ewen beds and the Oriskany limestone of Trilobite mountain.

Investigations in progress

Correlation study of the Helderberg, Oriskany and Grande Gréve
faunas. These investigations have progressed as opportunity has
afforded and the work is near completion. The richness of the Grande
Gréve and Percé fauna in comparison with those of the New York
Helderberg and Oriskany will make the faunal lists extensive, and
the close analysis indicates variations due to different physical condi-
tions, which in the fauna of a single geographic province might es-
cape notice. The problems presented by this study are not merely
those of the constitution of a fauna or certain allied faunas but rather
the variations due to distribution or occurring in the dissemination
of the fauna. Necessarily involved therewith is the interpretation of
the paleography of the early Devonic of eastern America and inci-
dental thereto the local geology of points both in New York and
Gaspe. It is hoped to complete this work in course of the present
year.

REPORT OF THE STATE PALEONTOLOGIST 1903 15

Graptolites of the slate belt of eastern New York. This series of

investigations on the nature of the graptolite faunas of New York

and their correlation with those of other parts of the world has been
completed so far as relates to the earlier rocks. A second part of
these investigations will include the later manifestations of the grap-
tolite faunas. The graptolites have proved under the recent studies
of European and American paleontologists the leading fossils for the
subdivision of the Siluric deposits into zones of life and correlation.
The first serious studies of their organization were made by James

Hall and Ebenezer Emmons, and Professor Hall’s elaborate and
beautifully illustrated memoir on the Graptolites of the Quebec Group,
1865, republished in the 20th annual report of the State Museum as
an “Introduction to the Study of the Graptolitidae” has been classical
for the study of these forms. Our knowledge of these objects has
however been greatly augmented by the investigations carried on by
European authors, specially by Lapworth on the distribution and
classification of the British graptolites. As far back as 1886 that
writer indicated the general parallelism in the succession of these
faunas in Canada and Great Britain, and in papers already published
in our own reports the same line of inquiry and demonstration has
been followed, together with contributions to their anatomy,
physiology and bionomy. The present work covers with some degree
of detail and in successive chapters the following subjects of inquiry:
history of the study of the graptolites; methods of investigation and
illustration ; terminology ; vertical range and geographic distribution ;
mode of existence; ontogeny and reproduction; morphology; his-
tology ; classification and phylogeny; synoptic tables; description of
species—7I in all, of which 29 are new.

Fauna of the Beekmantown and Chazy formations. For many years
before his death Professor Hall hoped for the opportunity to revise
his first volume of the Palaeontology of New York. Back in the
years from 1843 to 1847, when he was engaged in working out the
fauna of the older rocks, the collectors were few and the localities
but lightly explored. He did a work of the highest merit, but the
revolving years have added much to our knowledge of these early
faunas, though he found. no opportunity to return to them. A

10 NEW YORK STATE MUSEUM

special interest attaches to these early faunas of the earth, and their
development in what is now the basin of Lake Champlain is most
favorable, though it has not received merited attention. The collec-
tions which we have made in this region during the past five years
are extensive and are now undergoing review preliminary to a care-
ful reconsideration of the faunas. Actual additions to the numeri-
cal status of the faunas prove to be relatively numerous and of much
interest, and these are brought together and presented with this
report. Dr Ruedemann has been specially concerned in the collection
and study of these bodies and has begun the preparation of a series of

discussions pertaining thereto. I incorporate in this report some of

his papers relating to certain aspects of the cephalopods, and these
contributions will be found of more than ordinary interest in their
exposition of the structural characters of these creatures. Prof.
George H. Hudson of Plattsburg, who has long studied the rocks and
fossil faunas of Valcour island, has also cooperated in this work by
adding the descriptions of some interesting species discovered by him
in the Chazy formation there.

Fossil plants of the paleozoic rocks. In the history of this office no
serious effort has been specially directed to acquiring the plant re-
mains found in the New York rock formations. Not that these have
been intentionally ignored or overlooked but the collections which we
possess have been acquired incidentally to the exploitation of the
marine faunas. In the course of years these incidental collections
have grown to be of considerable moment and embrace a few speci-
mens of commanding size, such as the so called fern stumps from
Gilboa, the gigantic seaweed (Nematoxylon) from Monroe. Orange
co. and the great Lepidodendron from Naples—all from the Upper
Devonic. Some forty years ago Professor Hall interested Sir Wil-
liam Dawson, who was generally acknowledged the most expert stu-
dent of Devonic plants in America, in some of the New York
material and both at that time and subsequently Sir William pub-
lished brief accounts of some of our species. Professors D. P. Pen-
hallow and C. S. Prosser have also given incidental attention to this

class of fossils, though taken all together but little has been done in

REPORT OF THE STATE PALEONTOLOGIST 1903 17

this important and interesting field. During the past year Mr David
White, paleobotanist of the United States Geological Survey has
given our collections careful examination and has expressed his con-
viction of their great importance and completeness. It is proposed
with the aid of Mr White to elaborate the more interesting part
of these plant remains, and he has in accordance with this plan begun
preparing an introductory member of a series of papers relating to
this subject.

Investigations at Rondout. Some months of the year were re-
quired by Mr Gilbert van Ingen for preparing his report on the

geologic conditions at Rondout, which has already been published.

Fossil trails at Bidwell’s crossing. In my last report Prof. J. B.
Woodworth gave a brief illustrated account of certain remarkable
trails on the surface of the Potsdam sandstone exposed on the farm
of B. H. Palmer at Bidwell’s crossing near Sciota, Clinton co. These
trails are of a type which have frequently before been found in Pots-
dam strata and were termed by Sir William Logan, Climactichnites—
the ladder-shaped track—from the crossbars which traverse it. Some
years ago the State Museum undertook to remove a large slab of
these trails from a quarry at Port Henry but the sandstone layer
bearing them came out in such a fragmentary condition that the
pieces could not be matched together and the undertaking was a
qualified success. The exposure at Bidwell’s crossing was of extra-
ordinary interest in several respects. Over an area measuring about
30 feet in length by 10 feet in width and flush with the soil surface
of a partly cleared brush lot lay a series of long trails averaging 5
inches in width and some of them Io to 15 feet in length, the princi-
pal trails having a general parallelism to the length of the exposure, —
there being not less than 25 distinct trails visible on the slab. Each
of these long serpentlike trails, when complete, ends in a distinct oval |
impression which has been considered by Professor Woodworth as
the mark made by the body of the animal at rest. Such terminal

markings have not been observed before either independently
or in connection with these trails. Twenty-six of these oval
scars are shown on the slab. Logan, Hall and other writers

on such markings have generally regarded them as made. by

large trilobites and the undulated crossbars as. caused by the
oscillating ventral appendages of these animals in crawling over
the long exposures of the sand beach at ebb tide. Professor
Woodworth, however, believes that they were produced by a
worm or large univalve mollusk and has given an account of
some experiments made by himself to demonstrate that the mark-
ings must have been caused by a single rather than a multiple
opposing ‘surface, by the successive undulations of the gastropod
foot rather than by the multiple impression of a trilobite’s legs. We
know in fact neither the remains of a trilobite nor of a gastropod
mollusk in these rocks large enough to make such trails. Either
may have been present and like the reptiles whose tracks are found by
thousands in the Triassic sandstones of the Connecticut valley, have
left no other evidence of itself. From theoretic considerations a
crawling patelloid gastropod of commanding dimensions would have
well fitted the marine fauna of these ancient Cambric times.

This remarkable display of these ancient trails on the sands of
the primordial beach which skirted the primitive continent, now
the crystalline nucleus of the Adirondack mountains, had been
known to the countryside for many years but public attention was
drawn to it first by the publication referred to. A singular bit of folk-
lore has grown up about the trails as successive generations of set-
tlers have wondered at their nature. I have been seriously informed
by a venerable village philosopher that here was the very spot where
Christ, in accordance with Pentateuchal prophecy, trod on the Ser-
pent’s head, and this interpretation seemed generally accepted in some
considerable portion of the community as the true meaning of the
trails. The oval scars well simulate the print of the human foot lying
at or across the end of the serpentine trails.

The location of so striking a display of these trails afforded us an
opportunity for securing them for the museum. Accordingly an
agreement was entered into with the owner, Mr Palmer, in the form

20 NEW YORK STATE MUSEUM

of an option of purchase whenever it would become practicable for —

us to meet the necessary expense attending removal. At a later date
I entered into a contract with Frederick Braun for the removal of
the principal part of the exposure, having a length of 33 feet and a
width of 10 feet. The undertaking was an extraordinarily arduous
one, rendered the more difficult by the checking of the sandstone
along parallel or converging joint faces which made it necessary to
set each block in place in plaster of paris as it was removed. The
work of removal required two months and on its completion the ex-

posed slab had been taken out in six sections, the whole weighing 23

tons.

We have in this remarkable specimen an unexampled and impres-
sive exhibit. Facilities for the display of such specimens simply do
not exist in the present constitution of our museum but we can not
on that account let slip opportunities which may not return, for ac-
quiring such specimens. Storage has been found for these slabs with
the Flint Granite Co. at the Cemetery station.

Lease of the Spring House lot. In order to secure for the museum
a more extensive series of the rare crustaceans from the base of the
Salina group, described by Clifton J. Sarle and myself in previous
reports and to facilitate our own further studies of this fauna, I have
negotiated a lease of the property adjoining the Erie canal at Pitts-
ford for the purpose of excavating these remarkable fossils. We
purpose to break ground at this place with the opening of the next
field season.

Proposed salt mine at Wyoming. During the past year it was pro-

posed by the Silver Springs Salt Co. to put down a shaft for mining —

rock salt at Wyoming, Wyoming co. A company was organized for
this purpose with the name Oatka Salt Co. under the management
of John H. Duncan.

The section of the rock strata compiled by us some years ago
from the Livonia salt shaft afforded the most complete information
of the rock succession and sequence of faunas through 1600 feet of
strata yet recorded in this State. It would be an important contribu-
tion to this science if we could duplicate and supplement this elabo-
rate section, and consequently I entered into an understanding with

_ Mr Duncan, by whose courtesy we were to be permitted to carry on
- our examinations and collections during the sinking of the shaft.

Since the date of this arrangement Mr Duncan has retired from
the management of the company and comparatively little progress
has been made in carrying out the original plans for excavation.
Should, however, the undertaking be continued we expect to ane:
cute our examination as originally purposed.

Proposed exhibit for the St Louis Exposition. At the request of the
state commission proposals have been made in various form for an
exhibition of the work of this department. ‘The proposition which
has seemed to best meet the approbation of the commissioners in-
volves the exhibit of the slab of trails from the Potsdam sandstone,
already described, supplemented by a series of our publications. I
have been authorized to proceed with the preparation of this exhibit.

Purchase of the Ruedemann collection. Previous to his appoint-
ment on the staff of this division Dr Ruedemann had brought to-
gether an interesting collection of Silurian fossils from this State,
in which was included the material utilized as the basis of his study
of the graptolites and Conularia. We have acquired this collection
by purchase and it constitutes one of the important acquisitions of
the year, its type specimens being both numerous and important. A
list of its contents is given in full among the accessions.

Appointment of lithographer. By the death of Philip Ast, who

_had been connected with this department as lithographer for up-

ward of thirty years, it became necessary to fill the vacancy under
the civil service requirements. In due conformity therewith William
S. Barkentin has been appointed to the position.

PERCE
A brief sketch of its geology

BY JOHN M. CLARKE

In seeking the solution of some problems pertaining to the dis- it
tribution of the ancient faunas of New York, and the nature and 3
extent of the old land barriers and sea channels, one follows only a
blind lead if respect is had alone to such evidence as is found within ©
our own political boundaries. In the conservation of the factors 4
necessary to the reconstitution of these early stages in our history, © |
nature has been kind to New York and in the quality of fulness her 4
ancient faunas are not often excelled, but within these confines is q
but a part of the story; now and again a stage has been skipped :

here which is recorded elsewhere, or a phase is but obscurely pre- 7

sented in the panorama of New York events which in neighboring ~
territories is portrayed with lucid cogency. ;

Much of interest lies in the time and mode of introduction into ©
New York of the earliest faunas of the Devonic age. Here they are
represented in various degrees of effectiveness and profusion, and ~
for the most part follow with little evidence of interruption on those ~
of the great Siluric age preceding. The pathway of movement of :
these faunas along the old continental border lies to the northeast
and to the southwest, and the labors of our predecessors and col- :
leagues in the latter region have thrown much light on their distribu-
tion and travels through what is now the region cf the Appalach- —
ian mountains but what was then off the coast or along the water
ways of the ancient continent termed Appalachia.

Seeking such clues to the northeast led us a few years ago into ~
the county of Gaspé, province of Quebec, and the region just north
of Gaspé bay, and likewise to the exposures about Dalhousie N. B. ;
at the head of the Bay of Chaleurs, places where unequaled oppor- |
tunity is afforded for the study of some of the New York faunas —

. under a new aspect and in profuse development. More recently, on

REPORT OF THE STATE PALEONTOLOGIST 1903 1A

a similar errand, the writer has exploited the same factors as de-

_ veloped about the village of Percé on the coast of Gaspé just south

of Malbay and about 20 miles due south of the north shore of

Gaspé bay. In due time the results of the studies thus made will

be presented in some detail for the comparison of these ancient

ae

faunas with those of New York, for quite extensive collections have

been brought together from all the points mentioned, and we may

look for an important elucidation therefrom of some of the problems

‘to which reference has been made.

In this paper, however, it is not so ntuch the purpose to enter on

comparisons of results and correlations of faunas as to expound

with some brevity the singularly interesting geologic structure pre-
vailing at and about Percé, as derived from observations made in
the course of assembling the fossil faunas of the region.

The ancient fishing village of Percé is a spot of extraordinary
beauty of situation. It lies exposed to the full force of the sea on the
easternmost part of the Gaspé peninsula and no place could display
with more potency the tremendous destructive power of the sea
than this broken and deeply gnawed coast against which the north-
east blasts have beaten ages long. It is an old settlement, one of the
@idest in America. Soon after Jacques Cartier in 1535 roasted in
the Bay of Chaleurs and planted a cross at Douglastown on Gaspé
bay, fisherpeople from the shores of Brittany and the Channel islands
settled here under the overshadowing protection of the stupendous
and glorious Rocher Percé, from which the place takes name and

~ which today draws the amazed wonder of every passing sea traveler.

The narrow beach to the north of the rock and the long beach below
afforded a base of operations for the fishing, and here a settlement

was made long before Hendrik Hudson had wet keel in the waters

of New York.

Isolated and towering stands the Percé rock at the angle between
the North and South beaches, cut off from the shore by an interval of
300 feet, over which the waters roll, except at ebb tide, and beneath
which lies the zone of a great displacement of the rock masses. All
other presentments of the gnawing power of the ocean which the

136 NEW YORK STATE MUSEUM

writer has studied on American shores, in northern Scotland at
Scrabster and Caithness, in Hoy and the other islands of the Orkneys,
are surpassed in magnitude and effect by this leviathan rock. It lies |
like an immense Atlantic liner, almost at right angles to the course :
of the South cove, headed inward to the North cove wharf. Its
limestone strata, which stand vertical, rise to a hight of 290 feet |
at its highest landward apex, where today a weathered joint face i|
hangs out a triangular rock mass like a pennant flying at foremast |
peak. )

From the sharp landward bow the massive widens outward to a
diameter of about 300 feet and extends in length seaward 1500 feet, | |

Seaward face of the pillar at outer end of Percé rock; showing the arch

|
ot

its top sloping with undulating surface rapidly at first and then more ©
gently backward. Sternward stands an isolated rock pillar, remnant |
of a fallen arch which the seas brought down, as my good friend
Philip Le Boutillier tells me, on a rough 17th of June 1845. But the |
rock is still tunneled aft by a fine arch through which a boat at sail
might pass were it not for the breakers. On its rearward sea face is
another and smaller arch. The summit of the rock is the breeding-~
ground of thousands of gulls and cormorants, which make an ever
moving halo of white and black about the grassy slopes and jagged |
asperities of the surface and whose screams and calls are as |
sempiternal as the breaking of the surf on the fallen rocks. The |
cliff is virtually inaccessible. Local traditions and Sir Gilbert”)

Parker tell of its having been scaled, but be this as it may, the walls

are sheer and would demand surrender of the most daring. Clothed
in tints of red and yellow, which are the natural shades of the rock,
and veined with streaks of white, the colors of the cliffs change with
every passing cloud, alive with bright purples and lustrous bronze as
the sun shines full on it, in the cloud filtered light hanging like an
oriental tapestry in soft madders and browns, and when the land
mist hangs over it or the nor’easter is buffeting it, dark and minatory,
all its soft lines lost and its asperities stiffened in resistance.

Turning landward the eye rests first on the topography of the
shore line, Mt Joli, a low truncated rock cone connected at low tide
with the Pierced rock by a sand bar, and about a hundred yards away,
hence extending southward into another small headland, Cap Canon,
sometimes Battery point, all a rock escarpment of vertical strata not
more than 100 feet high at any point. To the south of this opens
the broad Robin fishing beach, which reaches away to the nearly
horizontal outcrops of red conglomerate at the opening of Len-
festy’s brook and beyond to the headland which bounds the South
cove, 2 miles away, Cap Blanc or Whitehead; another vertical mass
of limestones lying between and beneath the red rocks. To the north
of Mt Joli and the beach of the North cove, begin the Murailles, the
_ high rocky sea wall which fronts the Malbay, rising with a deeply
notched sky line in grassy and deeply furrowed slopes and falling
off sheer to the water’s edge; the tattered remains of a mountain
which stretched away into Malbay but has yielded its better part to
the restless tooth of the sea. The effect on the landscape of this
ragged escarpment is very striking but its impressiveness is appre-
ciated best only from the sea, from which it is alone approachable.
At the north end of the North cove the escarpment rises abruptly in
the calcareous and arenaceous shales of Cap Barré; thence northward
framing the angular recesses beaten out by the sea, the cliff becomes
even higher till the line reaches Red peak at the nerth and falls off
abruptly into the gorge of the Grande Coupe. Except for Cap Barré
these rocks are brilliantly tinted with reds and yellows and, we shall
presently observe, were a part of the tinted strata comprising the
Percé rock, though here the angle of their slope is greatly altered

and nearly conforms to the slopes of the mountain surface.

138 NEW YORK STATE MUSEUM

All these bold contours are brought closely together so that in the —

radius of a mile from the courthouse we embrace the Murailles, —
cliffs of Joli, Canon, the Percé rock, the broad intervales of the coves —

and the low south escarpments of the horizontal conglomerate. And
behind them all, as a background to the picture, rises Mt Ste Anne,
its lofty perpendicular precipices on the eastern face rising to a
hight of about 1400 feet. On the slopes of this easternmost member
of the cluster of summits known as Percé mountain, pious ardor has
cleared a broad way to the shrine at the top whence the eye travels
without obstruction to Anse du Cap and Grande Riviere southward,
and northward to Pointe St Peter across Malbay and to Shiphead
and the shores of Grande Greve across Gaspé bay; inland over the
rolling timbered wilderness toward the Shickshock mountains, and
seaward beyond the Percé rock to the island of Bonaventure 2 miles
away. This mountain is the summit of the great cap of red con-
glomerate which lies over and against the erect limestones of Percé,
Cap Canon and Cap Blanc, extends downward to the sea at the
Robin beach and makes the Percé reef, and doubtless continues
beneath the water to Bonaventure island where only this rock is
found.

From the slopes of Mt Ste Anne flow the little drainage ways of
the region, the stream of Le Coulé or Barré brook to the North
beach, Robin brook to the South beach and Lenfesty’s brook directly
through the rising escarpment of the Bonaventure rocks to the
south. |

This brief sketch of the topography of Percé will serve as the
only necessary introduction to the sketch of its geology which,
without going far afield from the confines of the settlement, follows.

GEOLOGY

Pretty much all that has been known of the geology of this region
we still owe to Sir William Logan, first director of the Geological
Survey of Canada. In 1844, the second season of his field work in
this capacity, Sir William made it his business to reconnoiter the
rocky and wild coasts of the Gaspé country, then and in the season
of 1845 making traverses from the Gulf of St Lawrence to the Bay

‘mented with mosquitos.” The venerable Mr Philip Le Boutillier
tells me of having piloted Sir William about the rocks of Percé and
with him scaling the summit of Mt Ste Anne.

In his classical Geology of Canada published in 1863 Logan sum-
marized the results of his observations here, and that part of his work
in which our interest more specially lies is his detailed account of
the limestones, sandstones and conglomerates of the region, enor-
mous series of sediments which he termed the Gaspé limestones;
Gaspé sandstones and Bonaventure conglomerates. Several of the
Canadian geologists have added much to our knowledge of these
formations; Dr Robert Bell, who early explored the region; Sir
William Dawson, who studied the plant remains of the Gaspé sand-
stone; Elkanah Billings, who has made known almost our entire
equipment of facts concerning the animal fossils of the rocks; R. W.
Ells, who as late as 1882 reviewed the general geologic features of
the country and added some important details, while Dr H. M. Ami
has contributed a few observations on the faunas.

The Gaspé limestones were defined by Logan from their most
remarkable development on the narrow tongue of land which con-
Stitutes the peninsula of-Cape Gaspé eastward of Cape Rozier on
the north and Little Gaspé on the south. Here the succession is
apparently uninterrupted, the dip estimated at about s.w. 24°, and
‘the series rests unconformably on the shales of Cambric age at Cape
Rozier. Through this narrow neck of land not more than a mile
Seeeeeirom the Gulf of St Lawrence to Gaspé bay at
Grande Gréve run two limestone escarpments, the northern
terminating in Cape Gaspé, the southern in Shiphead and the
two separated by an eroded, not structural, drainage way. Logan
estimated the thickness of this continuous mass at about 2000 feet,
_and divided it into eight parts, divisions 1 to 8, between which was
found no evidence of unconformity but some notable distinctions
in quality, the strata becoming more highly calcareous with some
‘intermixture of arenaceous matter toward the top. All were re-

IAO NEW YORK STATE MUSEUM

garded by him as of the age of the Lower Helderberg of New York,
at a time when the Helderberg fauna was not estimated with pre-
cision. Almost all the divisions were found to be fossiliferous, but
the uppermost, 7 and 8, specially so. _

It became evident from the identification of the fossils of the
upper beds by Billings that divisions 7 and 8 correspond more
nearly in fauna to the Oriskany of New York than to the Helder-
berg, and these have been generally conceded to have this
equivalence, but of the fauna of the lower beds, its composition and
variations, we know only enough to see therein clues to the origin
of the later fauna and invaluable lights on the derivation of all early
Devonic faunas of the Atlantic and Mississippian provinces. Con-
trasted with the other beds in profusion of fossils and diversity of
species, divisions 7 and 8 have been distinctively designated, Dr
Ami having proposed to call these beds the Grande Gréve lime-
stones. To them Logan ascribed a thickness of about 800 feet, and
in them is a fauna which differs from that of the Oriskany of
eastern New York in as many respects as it agrees therewith and yet
is bound to it by such striking paleontologic features as the co-
existence of Rensselaeria, Megalanteris, Hipparionyx, Chonostro-
phia, Spirifer murchisoni, 5S. arenosus) and mame
other organisms.

Over the Grande Gréve limestones lie the Gaspé sandstones of
Logan, shown in apparently conformable contact with the rocks
below at Little Gaspé, and attaining an immense thickness. Sir
William estimated them at over 7000 feet and subdivided them

largely on lithologic characters, as they vary from drab ferruginous,

fine grained quartz and feldspar sandstone to coarse conglomerates
and red sandstones, the latter being mostly towardthe top. From
the lower beds Dawson described many interesting plant remains
all presenting the aspect of such sedimentation as characterizes both
in New York and Europe the deposits of the Devonic or Old Red
lakes or lagoons. The lower beds about Gaspé basin contain a
fairly rich marine fauna which has been partly described by Billings
and to which we have been able to add evidences of both early and

middle Devonic age.

REPORT OF THE STATE PALEONTOLOGIST 1903 WAT

66

| ih the region about Percé the presence of limestones corresponding
: those at Gaspé “on the horizon of the Lower Helderberg and

Oriskany ” [Geol. Can. 1863. p.439] was noted by Logan in con-
ne ction with his rapid but very lucid sketch of the geology of the
coast section from Gaspé to the Bay of Chaleurs. Some lists of

fossils were given, though these have only in part been verified by

‘subsequent identification, Mr Billings having described a goodly
number from the uppermost horizons represented in the Percé rock.

1s

The vertical strata of Percé rock

On analyzing the relations of the various limestones and shale
masses exposed about Percé, based specially on the character of the
fossils, we shall find in the massives now dissevered either by topog-
taphy or displacement, the key to their geologic structure not in
their apparent relations, their attitude one toward another, but here
again, as ever, in the nature of their fossil contents, which in them-
selves afford the solution to the geologic enigma of the region.

Perce rock massive. The tinted strata of Percé rock, standing

almost erect, or according to Logan, overhanging the perpendicular

142 NEW YORK STATE MUS&£UM

10° northwardly, are the home of a great profusion of fossils many
of which are common to the upper or Grande Greve limestones of :
Cape Gaspé. | ;

As to the essential concurrence of these faunas in a broad sense
there can be no question but the careful comparison of them leave f
room for doubt whether the actual horizon of the Percé rock im
represented in the series at Grande Gréve. Inasmuch as the rock”
succession of Cape Gaspé is constant as far as it extends there is
room for the provisional suggestion that the horizon of the Percé”

rock with the precise expression of its fauna is there modified, but in-
dicates an early stage of the Grande Gréve limestones. Percé rock”
is not divisible faunally and its strata show no persistent differences. 3
They are indifferently yellow and red according to degree of oxida-
tion, and the process of color change, irrespective of sedimentation
lines or structural features, is everywhere finely marked. They are
highly veined with calcite seams, and the yellows seem, if anything, .
to predominate on the south, the reds on the north. Mr Ells speaks i
of their containing interleaved conglomerates but of such we have t
seen nothing. We may not at this time give a statement of exact or f
final determinations of its species, but the following suffices to in-~
dicate the character of the fauna. To these we shall hope to return |
in future with the detailed comparisons needful to ascertain the
organic and time relations of this fauna to those of the New York :
series. Such species as are here indicated with unfamiliar names
will be fully defined and illustrated hereafter.

It will be seen from the foregoing that the Percé fauna is more!

extremely abundant there, e. g. Eatonia peculiari Ss,

Hipparionyx proximus are absent here, while here

are profusely developed. Again striking species in each fauna are |

There is thus a difference in the relation of the elements of the :

faunas to each other and also to those of New York. Hence there

may be in these faunal characters a reason for regarding these lime-

stones as the expression of a distinct substage in the deposition

period of the Grande Greve beds.

On the Murailles or the high rock wall above the North cove we |

find Percé strata again. Rounding Cap Barré where the dip of the

‘the Blowhole, a sea cavern gnawed out by the waves. the tinted Percé

strata again appear, but here lying at a steep angle, 20° to 40° to
the southeast and abutting palpably against the thrust plane of a
fault which is well marked in the face of the cliff, sloping obliquely
downward and to the north. The line of displacement is well en-
forced by the contrast in color between the downthrown yellow and
red strata and the more somber grays of the Cap Barré massive.
Logan noted the fact that these downthrown strata were of equivalent
age and probably a part of the Percé rock, and Ells cites the occur-

Section at Blowhole. Cap Barré beds at left, downthrown Percé beds at right

Megalanteris plicata Spirifer arenosus

are they in any wise so abundant as at Perce rock. i

These Percé beds about the Blowhole are probably again down-
thrown in themselves in their further extension along the Murailles
but without essential change of dip, for this same southward dip is
well expressed in the angle of the landward slope of the cliff and is
apparent as far as Le Coulé on Barré brook where Percé fossils were
also found. The latter seem to be the summit beds of the limestones
and from them the following species were obtained.

the Grand Coupe, as well as in Le Coulé as just stated. In the great

Bea iront of Red peak, the high face rising 660 feet over the

_ water is believed to bring up the lower gray limestones in conformity

-and, though these beds are difficult of access and have not been
properly studied, it is likely that here are the strata which fill the
broken interval between the Percé beds and those beneath, the rocks
of Cap Barré and perhaps also in part those of Cap Blanc.

As a whole, we may say of the Percé beds that though they are
now but remnants left by recent rapid and profound changes in
topography, due to the tremendous destructive energy of the sea,
_and their surfaces, both on the Percé rock and in the Murailles, are
the slopes of lost mountains, yet they have been subjected to dis-
turbances in themselves much greater and much more ancient, wit-
nessed by their difference in inclination and their tremendous
displacements. These displacements we shall endeavor to portray
more particularly in summing up the evidence relating to the geologic
structure of the region.

There is little evidence yet on which to base any kind of sub-
division of the Percé rock mass, either from its fossils or its rocks.
The yellow beds seem to bear in greater abundance the prolific
res sO vonctes cafladensis, Leptostrophia
@eene, Chonostrophia. etc., and the red layers the trilobite
Meeemiains, oOpirifer-arenosus; S. murchisoni, etc.,
but this occurrence is open to constant exception.!

Cap Barre beds. In first considering the limestones of Percé rock
we have started with the latest of the limestone deposits. In close if
not immediate succession beneath them seem to follow the gray
schists exposed only at Cap Barré, the southernmost and lowest
point of the Murailles.

These beds consist of thin, sandy, blue gray limestones with inter-
calated shale, the rock becoming reddish at the top beneath the soil
cap. They dip northeast 30° to 40°, which is an angle not repro-

“Most of the fossils from the Percé rock described by Billings were evi-
dently picked up loose at the foot of Mt Joli whither they are washed in
_ great quantity from the rock itself. Hence Billings, not personally acquainted
with the situation, frequently cites Mt Joli as a locality of these fossils which
is misleading for the Joli mass is of very different age.

duced in any of the strata elsewhere exposed, and their attitude
toward the Percé strata farther north has just been expounded, from |
which we may infer that these rocks are normally subjacent to the
latter and have been separated therefrom by the downthrow of the
superjacent mass. These Cap Barré beds, so far as exposed, may
attain a thickness of 75 to 100 feet. Their relations with the strata
at Mt Joli are determinable from no structural relation exhibited,
for they are separated from the latter by the long interval of the

Cap Barre from North cove

North cove. These beds contain fossils, but very sparsely. I have
found a few Lingulas and an Ambocoelia-like brachiopod probably
allied to Spirifer modestus Hall, which is a Helderbems
species, also a small corrugated Leptostrophia like L. oriskania

Clarke, but the age and position of the strata are decisively indicated ;
by the presence of a species of the trilobite Dicranurus. |
This fossil is of more than ordinary interest. The genus Di-
cranurus has been described heretofore only from two geologic.
formations, the Helderberg (New Scotland beds and Coeymans

REPORT OF THE STATE PALEONTOLOGIST 1903 153

limestone) of eastern New York (D. hamatus Conrad) and

from the equivalent horizon Etage G, of Bohemia (D. mon-
memersds. Bartande sp.). /The species from Cap Barré (D.
limenarcha ) is represented only by an incomplete cephalon
but it is rarely that any other part of the genus has been observed in

any of its occurrences. It was a species larger than the New York

form and perhaps even larger than the Bohemian. Its elongate,
subconate middle lobe is well delimited by a deep nuchal furrow, the

lateral lobes are separated by a shallow transverse or oblique groove,

while the axial diameter of the occipital ring from the base of the

Dicranurus limenarcha

central lobe to the fork of the spine is relatively less than in D.
hamatus. The free cheeks were attached to this specimen, but
they have not been preserved except along the sutures. The great
neck spines are highly divergent and very heavy. Barrande gave
mieeanele of divergence in D. monstrosus as 60°,.in D.
Mamatus itis 45°,inD. limenarcha it is 80°, measured from
the central occipital tubercle as apex, axially for one third of the
length of the spines. These spines are curved outward, downward
and back, and probably made a deep recurvature as in the other
species, though they are not preserved at the tips. On their proximal

extent is a low median depression. The surface of the head is

covered with acute pustules scattered sparsely with very much finer

154 NEW YORK STATE MUSEUM

ones between. On the occipital ring the central pustule, which is ©
more conspicuous than the rest as in other species, is punctuated at |
the top by a circle of depressions. The head had an original length |
to the point of recurvature of the neck spines of about 40mm, the ;
greatest divergence of the spines is 29mm, the axial length to the
angle of the spines, 23mm, of which 9mm belong to the occipital
ring ; width between the eyes, 25mm.

From no other evidence have we so satisfactory a basis for the |
conclusion that the Cap Barré beds follow’close below the beds of |
Percé rock and above those of Mt Joli. We may therefore conclude :
that either these strata lie buried in the tide-swept interval between |
the Percé rock and the outermost vertical strata belonging to the
Mt Joli massive, or that, originally in place here, they have been ©
pinched out by faulting. |

The space between these two massives not in the line of the con- |
necting sand spit but rather in the line of vertical thickness of the —
strata, at right angles to their present position, is barely enough to
admit the beds of Cap Barré. Doubtless they have been largely
squeezed out in faulting and pitched over on their side where they |
now lie, though some part of them may remain in the interval, to be
exposed by some favoring neap tide to the eye of the trained observer.

Shales of the North beach. Faintly exposed at spots in the bank
along the North beach, in the dugway road to the wharf and at points
from there toward Mt Joli are beds of soft shale usually gray, some-_ |
times black, blue black and green black, lying under the reddish soil
cap. These are slightly inclined away from the vertical and it is
not in my present judgment at all certain that they are continuous
with the Joli escarpment which we are about to consider. They have
furnished no fossils and outside of them, beneath the water not far |
from the wharf, is a vertical reef in which cyathophylloid and favosite
corals occur and these are doubtless the latest and uppermost beds
of the Joli series. Soft drab shales similar to those on the North
beach appear also in the roadway between the Cap Canon cliff and
the escarpment at Lamb’s limekiln, and I have inferred therefrom
the presence of an infaulting through which this mass of shales has
been displaced from its proper position.

j Mt Joli massive. The erect strata of gray thin limestones and
calcareous shales which constitute the low headland at Mt Joli begin
‘not at the scarp itself, but at low water may be seen extending well
out from the shore. Along the North beach these outlying strata
form little reefs, but the intervals between them and the wall of the
promontory is concealed by the beach. Taking the Mt Joli massive

East face of Mt Joli

as a whole, it has an approximate length along the sea front of 700
feet, the highest point being at the north, the upper slope declining
southerly, ending rather abruptly, and the rock mass being separated
from that of Cap Canon by an unexposed and probably entirely
interrupted area of about 350 feet. There is little change in the
lithologic composition of the strata composing Mt Joli, but there is
definite evidence of displacement in the mass itself. For the greater

156 NEW YORK Stare WiUSHUMN

part of the length of the sea wall the strata are essentially vertical |
with slight undulations; but at a distance of about 250 feet from the |
south end of the cliff the strata become much more irregular, main- |
taining their essentially vertical attitude but are folded and slightly |
displaced among themselves and faulted against the more erect |
strata of the main part of the mountain. The southern part of the |
mass is composed of strata similar to those of the northern but in-
creasingly slaty in composition. In both parts of this Mt Joli mas- |

sive fossils were found, but they are by no means of common
occurrence; moreover they are wedged in the vertical strata so that

their extraction is not easily accomplished. From their calcareous |

layers, which with the eroded interleaved shales form the outermost
northern reach of the strata and are exposed only at low tide as reefs,
were obtained a few fossils: Platyceras, large species of Helderberg
type; Zaphrentis corticata DBillmes= |Z emmoar onus
Billings. :

The shaly layers on the high vertical north face of the scarp have

afforded species provisionally identified as follows:

Te edhitaaitacys . 8 Stropheodonta cf. varistriata Con-
2 Monograptus cf. clintonensis Hall rad .

3 Duncanella cf. borealis Nich. 9 Spirifer cf. niagarensis Conrad

4 Streptelasma cf. caliculus Hall 10 Spirifer modestus Hall?

5 Michelinia cf. lenticularis Hall Il Cypricardinia af. sublamellosam
6 Dalmanella cf. perelegans Hall Hall

7 Leptaéna rhomboidalis Wilckens 12 Phacops sp.

Giving special attention to the trilobite in which lies the clearest
indication of geologic age, we find it to be a fully developed Phacops
such as nowhere occurs in the typical Siluric deposits of the Missis-
sippian sea or Appalachian gulf. Its glabella is large, rotund and
coarsely pustulose, the glabellar furrows obsolete, eyes large and the
genal angles have minute spinules. The pygidium is broad, the axis
having six to eight well defined rings, the first bearing a prominent
tubercle, the pleurae having five to six ribs all grooved and separated
by deep furrows. These structural points indicate an early period in
the history of the genus, hence if Siluric, a final stage. Whe species
is equivalent to Phacops logani of the Helderberg and
Oriskany of New York, of the Percé rock and the Grande Gréve
limestones.

Mt Joli then with its 700 feet of calcareous strata represents a
long stretch of Siluric time, and it would appear that the apparent
line of main faulting of the southern or lower against the northern |
or upper mass, marks the disappearance of some interval in the
lower elements of the series as indicated: Such departure as there
has been from the vertical position of the strata is in the direction
of overthrow so that the lower lean up against the higher strata. |

on of Mt Joli is a beach interval where no rock exposure is seen
for a length of 345 feet. The grass grown bank shows a red soil
cap and in it here and ‘there are blocks of red conglomerate, as
though (and to such evidence we may return) deposition of the red
conglomerates was over a rough bottom wherein this clay-banked
peach was a deeply gullied line of disturbance. The rocks of Cap
‘Canon are calcareous shales and black argillaceous slates, greatly

measure which have produced glistening shear faces, veined in all
directions, richly jointed and cleaved, but in spite of these internal
‘displacements the vertical attitude of the mass is still apparent with
a slight general inclination toward the north.

This mass, irrespective of its undulations has a sea front 630 feet
long and this is approximately a measure of its actual thickness. In
lithologic character there is a marked difference between it and that
of Joli, chiefly expressed in its slatiness. It has, after repeated
‘search, revealed no fossils.

On the summit of Cap Canon is the summer home of Mr Frederidh
James. From this spot the well grassed rock surface slopes deep
landward, then abruptly rises at a distance of about 400 feet from
the edge of the cliff and the strata stand upright again in a bare
dome of rock at which is a now abandoned limekiln. The rock here
was burned by Mr Philip Le Boutillier and from him [| learn that
the burning has been only partly successful but at times a puret
limestone has been brought to the kiln from the outcrops at Cap
Blanc, 2 miles south. '

Limekiln massive. The rocks at the Limekiln are as a whole nota-
bly distinct in character from those constituting Cap Canon though
they stand vertical and hold the attitude characterizing the rest of the
strata. |

These beds are limestones much seamed with calcite veinules and
heavy bedded, largely a limestone conglomerate but with no jaspet
pebbles as in the limestone conglomerate of Mt Ste Anne to which
reference will be made. They have a thickness of 200 feet. A single
bed of a similar conglomerate was observed infolded in the schists
of Cap Canon.

Just beneath these on the south slope are even bedded impure gray
limestones and from these latter only have fossils been obtained
There is to my mind a reasonable security in regarding these fossi Ei
bearing rocks here in place, though blocks have been found only in
displaced condition. Concerning this point, however, I would not
venture to be unqualified in my statement. These fossils are:

Plectambonites sericeus Sow. (very Protozyga exigua Hall

common ) Ambonychia sp.
Rafinesquina, a geniculated species Ceraurus pleurexanthemus Green
Leptaena rhomboidalis Wilckens

Though few in number, the species abound in individuals and the”

assemblage clearly indicates a later stage of Lower Siluric than the”
fauna in the south flank of Mt Joli, somewhere equivalent to middle ~
or upper Trenton age. The road in front of Mr James’s house, as
it rises from the depression between the escarpment and Cap Cano ‘
shows trace of an infaulted mass of soft, brown shale elsewhere

have construed the fauna correctly, the place of the Limekiln rocks is
between the south and north flanks of Joli or is a corresponding
portion in the series. We may find no clear evidence of the necessary
fault plane in that escarpment, but this cliff at the Limekiln is evi-
dently cut off by faults both therefrom and from the Cap Canon
mass.

Cap Blanc massive. From Cap Canon southward for a distance
of 2 miles sweeps, first, the broad Robin fishing beach or South cove
buttressed at the south by horizontal or slightly dipping beds of red
sandstone and conglomerates rising into a constantly more elevated
sea wall till Cap Blanc is reached. Here as one turns the point of
the headland and rounds the light, vertical limestone strata are once
more exposed and their contrast in color to the horizontal or slightly
northeast dipping red strata which overlie them and abut against their
‘slopes, gives name to the place. The sea wall is sheer and the foot
of the cliff accessible with risk, even by water.

The vertical thickness of these rocks measuring from the point of
the cape southward is estimated at 700 to 1000 feet. They are light
gray in general effect and the succession of the strata is obscurely
presented in the highway and field outcrops. With the slight inclina-
tion of the strata away from the vertical toward the north as seen
in the Mt Joli massive, we first find in t’ ce highway cut ascending the
cliff from the north a red limestone, suggesting in tint the Percé
rock and carrying

Ortonia Trematopora (very slender branches)

Trochonema Small Whitfieldella-like brachiopods

But principally and oftenest a large and heavy shelled pelecypod
having a broad cardinal plate extending inward from the hinge line,
not attached to the bottom of the valves nor thickened at its junction
therewith. This rock is of such character that it breaks in almost
@ny direction except along the surface of these fossils but one
example of this species has the valves together and this, sectioned
vertically shows these projecting plates not in apposition as though

162 NEW YORK STATE MUSEUM

connected with the articulation of the valves, but standing apart
with a well defined space between, indicating that they are a broad
chondrophore. Further material will be necessary to elucidate the 4
nature of this shell. | .

It is clear however, from the list given, even though generic dete : |
minations only seem safe at present, that this congeries represents
a stage of late Siluric, clearly older than the fauna of the Perce

rock, probably older than the beds of Cap Barré, but not necessarily j
older than the north flank of the Mt Joli massive. These beds, the
highest in the series, lie lowest as the entire mass is slightly overs
turned. Working southward over the remaining exposures in
exceedingly rainy and cheerless weather, it is probable that we have
overlooked much that will throw light on the relations of the serie .
Beyond the light, seaward of the road, on the edges of the escarp=
ment in the field whence the purer layers of limestone have been
removed for burning, and which appertain to the lower and southern:
most part of the series here represented, after careful search fossil3_
were found, not in the blue and more abundant limestone, but in thir | \
clinking limestone plates. | :
The mode of preservation here is singularly favorable were the 4
material sufficiently abundant, the fossils being weathered out on the —
surfaces of the plates and doubtless the fauna will prove an interest
ing and instructive one under more favorable opportunities for
exploration. These slabs have afforded:
Spicules of hexactinellid sponges Whitfieldella cf. bisulcata
Platyostoma Orthothetes (small)

Many crinoid stems and an occasional crushed head with ornamented
plates resembling Glyptocrinus.

Calymmene (small species) Phacops of P. logani type
Bumastus (small species) Phacops sp.

Taking up for more minute consideration the trilobites, the time
values of whose structure is best understood, we may note
1 The common species of Phacops is fully developed, with glabellar
lobes fused by almost entire disappearance of the furrows, eyes
rather small, cheeks rounded with the faintest trace, if any, of the
genal spinules indicating early age, and the doublure of the cephalon

REPORT OF THE STATE PALEONTOLOGIST 1903 163

crenulated to a degree shown only in pronounced development in
this genus.
The pygidium is short and stout with a short blunt axis bearing
four defined rings but eight axial sulci can be counted. Of the
pleural ribs but two can be counted and these are flat and sulcate.
This con:pletely developed Phacops is in itself indication of either
Devonic age or a very late stage of Siluric. In the Mississippian
Siluric no such form presenting fully matured cephalic features is
known. The species, however, shows in the sulcate pygidial ribs
index of early phylogenetic stage. It can not be identified with the
Helderbergian and Oriskany P. logani which is found in the
Percé rock and at Joli, but approaches thereto.

2 The second species of Phacops is known only from its cephalon
which is of a singular and unusual type. In this the first furrows
of the glabella are faint without entering the dorsal furrows and are
like a pair of eyebrows, defining obscure round lobes, behind which
the second lobes are also round and better defined, while the third
lobes are obscure. The eyes are small and with few lenses, the
cheeks broad, flat and dalmanitiform, rvzming out into short flat
spines at the angles.

The aspect of the species is that of immaturity with reference to
the development of the genus Phacops and presents the combination

with features pertaining to Dalmanites which is indicial of the pas-
sage forms from the latter to the former. The aspect of this cran-
idium is shown in some early Devonic forms such as P. (D.)
tumilobus Clarke from the Amazonas but without association
with cheeks of notable Dalmanites type.

One of these forms of Phacops indicating late age is counter-

balanced by the somewhat earlier expression of the other and this

combination is verified by the presence of Bumastus and Calymmene.

is either not there clearly presented or is presented here with some
change of faunal association. It is not, in our view, a section of the :
series there lost by faulting out, but the expression of the later Siluric_
beds there, with a variant geographic association of species. .

Relations of limestone masses about Perce. We have. estimated
roughly the thickness of the masses here discussed as follows: |

2030-2130 feet

Thus there is a development of approximately 2000 feet of lime-_
stones representing the geologic series from early Siluric (Black
River-Trenton) to well into the early Devonic or Oriskany. The
Cap Blanc massive with a thickness of 700 to 1000 feet is not in our
judgment an addition to, but a repetition of a part of the series. The
rocks on the Murailles are likewise regarded as not adding to, but }
repeating the series in part, with the exception of the Cap Barré |
beds which are partially provided for in the rock interval between
Mt Joli and the Percé rock. In order of succession from the top

downward, we should, from present evidence arrange the masses |

thus:
Perce beds (?) Limekiln beds
Cap Barré beds Mt Joli (south flank)
Mt Joli (north flank) Cap Canon

Some doubt will attach to the proper position of the strata of the |
Limekiln for the reasons already stated.
With the foregoing succession we deduce a profound displacement
between the Percé rock and the north face of Mt Joli by which the |
beds of Cap Barré for a thickness of 100 or more feet were squeezed |
out, and their remnant overturned to their present place and atti-

tude, a quarter mile away, and their dip reversed.

REPORT OF THE STATE PALEONTOLOGIST I903 165

On the face of Mt Joli among the vertical strata we believe it
probable that a displacement has taken place by a downthrow which
has squeezed out the rocks represented by the fauna found in the
beds at the Limekiln. This is inferred wholly from the nature of the
fossils of the latter.. Their place is here in the succession of the faunas,
but should subsequent developments tend to show that the fossils
there found were derived from another source, either from the rocks
of Cap Blanc or the limestones northward toward the Barachois, we
need not open the cliff to admit this mass. On the other hand, were
such the evidence, it would seem to be the remnant infaulted by a
displacement whose zone rests where now is the short beach between
Joli and Cap Canon.

The displacement we have already noted in the south flank of Mt
Joli and shown in the rock wall is within the succession of lower
Siluric faunas, these fossils occurring on both sides, and we hence
infer it not to have been of great depth.

On the Murailles we find the clearly defined line of displacement
along which the Percé beds have slipped down over the Barré beds
inverting their dip, and this entire mass of Barré and Percé beds
was evidently cut off by the longer line of faulting from the Percé
rock. These lines of probable displacement of the limestone masses
we have expressed on the map adjoining.

Surface conditions preceding deposition of red sandstone and con-
glomerates. Strip off the mantle of red, almost horizontal conglom-
erate through which the limestone cliffs project their heads and the
country would present an irregular series of jagged limestone bluffs,
the remnants of broken and eroded folds, which the tooth of sub-

aerial weathering, of stream erosion and the endless gnawing of the
Ocean, left standing. The vertical position of most of those once
horizontal rocks is in itself an indication of the immense proportions
) attained by the primary folding of the strata. The presence of an
| anticline at Percé was recognized by Logan, and without venturing
_to go so far afield as to connect the structures here with those beyond
| the scope of this sketch, it may be said that the simplest explanation
of the relation of the Percé limestones with the series as exhibited

| from Little Gaspé to Shiphead is a great syncline beneath the sea, of

Bonaventure conglomerate at summit of Mt Ste Anne

Immense time was necessary for the destruction of these old folds
before the ragged country was carried down beneath the water level
for the deposition of the red conglomerates and sandstones.

Red sandstones, conglomerates and limestones

The country is so completely sheeted with these horizontal deposits
that they may be studied at numerous places away from the lime-
Stone cliffs, but nowhere in their continuity so well as along the slopes
of Mt Ste Anne. Let us however, first take note of the opinions
which have been expressed by Logan and Ells concerning these

168 NEW YORK STATE MUSEUM

deposits. We have remarked that while almost horizontal, there is
a definite dip in the strata to the northeast which is conspicuously
displayed in the precipitous eastern face of Mt Ste Anne, and in the |
western wall of the distant Bonaventure island, 3 miles out to sea.
From Bonaventure island, which is wholly composed of these strata,
Logan derived the term Bonaventure which he originally applied to
the entire series of these rocks, chiefly conglomerates, and these he ©
regarded as of Carbonic age. Ells, approaching the region from a
study of the conglomerates of the Bay of Chaleurs interstratified in
which have been found Devonic fossils (chiefly fishes of Old Red
sandstone type) recognizes differences in the conglomerate mass and
assigns to the Bonaventure the upper beds of Mt Ste Anne and all
those covering Bonaventure island with which they were continuous,
believes an unconformity to exist between the upper and lower con-
glomerates of Mt Ste Anne and assigns the latter including the
sandstones and interbedded limestones, to the Upper Devonic age.
Of such interruptions of deposition in the conglomerates we could
find no evidence in the Percé region but if we interpret these inter-
esting sediments aright, it is quite in accordance with the judgment
we have been able to form, that they do actually represent a period
of time partly Devonic but transcending that era into the next suc-
ceeding. We may note the character of these strata in some detail,
beginning at the lowest accessible exposures. |

Shore between Robin beach and Cap Blane. Near the mouth of
Lenfesty’s brook we find in the shore wall an exposure about 25
feet in hight, at the base of which are red shales overlain by red
and white sandstones and conglomerates, then red shales followed by
conglomerates and above these are gray hydraulic limestones. The
conglomerates are variable in lateral extent, passing into sandstones
but reappearing in great force to the south, the limestones disappear-
ing. The pebbles of the conglomerate are at this horizon, largely
of jasper and with a very small percentage of limestone of the char-
acter of the higher beds. On Bonaventure island the conglomerates
also contain much jasper but the limestone pebbles predominate.

Mt Ste Anne. The sandstones and limestones of the lower beds
are also seen in climbing Mt Ste Anne and in the vicinity of Irish-

REPORT OF THE STATE PALEONTOLOGIST 1903 I 69

town. All the higher beds of Mt Ste Anne are composed of lime-
stone conglomerates with very little jasper and as the cement is
calcareous it falls away freely. It was noted by Ells that these
pebbles and boulders of the conglomerate contain Siluric fossils.
We have found inthem Chonetes canadensis, Spirifer
Zmmemiuseani Megalanteris plicata, Meristella
@rcuata and Dalmanites perceensis, all fossils of the

Limestone conglomerate, Mt Ste Anne

Perce rock; also Halysites catenularia, Heliolites, and in
some sandstone pebbles a small Spirifer like S. vanuxemi.
These fossil-bearing pebbles were found to the summit of the moun-
tain even in the platform on which rests the shrine of Ste Anne.
As this point is nearly 1400 feet above tide, the thickness of these
ted beds can not be less than 1200 feet and down along the shore
land it seems to fill or to have stained all the depressions between
the scarps of vertical limestone so that even on the shore when the
soil is opened, blocks of the conglomerate are set free.

170 NEW YORK. STATE? MUSEUM

General remarks on the conglomerates

One is struck with the absence in the Percé region of the great

thickness of the rusty brown Gaspé sandstones which at Little Gaspé

rest conformably on the limestones and at Gaspé Basin carry marine

fossils. Doubtless we are to find the contemporary of these deposits

in the red and white sandstones of Percé, but they are only feebly

developed and to them as an equivalent of the work elsewhere done,

we must add some part of the conglomerate series. We follow |

ideas before expressed in regard to the tremendous deposits of the

Gaspe sandstone, as sediments laid down first along an embayed ©

coast and eventually in a deep coastal estuary which received heavy |

drainage from an elevated and rapidly decaying land surface. That

estuary may have extended far to the southeast and at times it

appears to have been shut off from the ocean entirely by the upbuild-— |

ing of bars across its mouth but it was virtually and for long periods

a coastal lagoon subject to inroads from without in times of stress.

Then was the period of Old Red lakes in New York, in Scotland,
Orkney and Russia. They did not all begin at the same period of —

time nor continue their existence for equal times; some began in the ©

late Siluric, others in middle Devonic, several are known to have
continued their existence beyond the Devonic and into the Carbonic.

So here; we are disposed to believe, this peculiar mode of sedimenta-

tion has transcended the limits of Devonic time and entered the Car- —

bonic, though we have no traces of marine life of either period after
the deposition was once established. The conglomerates of eastern

Gaspé are contrasted with the sandstones of the more westerly parts

of the county, and we may interpret them as the deposits of the

seaward ends of the long estuary where for countless time the waters —

of the sea beat, as today, on the upturned edges of the ancient lime-_
stone cliffs and rolled their fragments up along the margin of an ever

sinking continent.

Conclusion

From the future detailed study of the faunas preserved in this
series of Siluric and Devonic limestones, we may expect a flood of

light on the significance of contemporaneous faunas in the northern

REPORT OF THE STATE PALEONTOLOGIST 1903 7k

Appalachian basin. In the Perce rock and its more northerly devel-
opment in the limestones of Grande Greve, we confidently look for
a solution of the questions of origin and derivation of the faunas
which represent the earliest Devonic life of the Appalachian basin,
and their path of migration once determined, evidence to infer the
outline of the continental borders and the definition of the water-
ways.

In this brief sketch we have omitted from consideration through
lack of personal acquaintance, reference to the Siluric limestones
which occur in detached masses along the Malbay to the north, and
at spots remote from Percé, along the southern coast. When these
have been studied in detail, the entire series will be found to present
an important supplement to our present knowledge of the factors of
that ancient time.

INTRODUCTION

Trilobite mountain, which is situated 3 miles southeast of Port
Jervis, Orange co. N. Y., is a ridge with a maximum hight of about
750 feet, trending in a northeast-southwest direction. The ridge is
about 2 miles long by 1 mile wide and is bounded on the northwest
by the Neversink river and on the southeast by the marsh separating
this ridge from Shawangunk mountain, which like all other of the
Blue Ridge ranges trends from the northeast to the southwest.

Both ‘the valley of the Neversink and that containing the marsh
between the Shawangunk and Trilobite mountains are simple mon-

oclinal valleys [fig. 1]4. The Onondaga and Marcellus formations
underlie the former, the upper Medina to Manlius the latter valley.

Trilobite mountain, as noted by Dr Barrett?, constitutes one of a
series of anticlines extending in a northeast-southwest direction. In

other words, this monocline is crossed by a “ secondary system of
flexures which cause the Helderberg Ridge to rise and sink in a
succession of anticlinal and synclinal folds . . . The roads are in
the synclinals and the limestone quarries are in the southeast fronts
of the anticlinals . . . Bennett’s quarry is in one of these; Near-
pass’s and Buckley’s quarries lie south and north of it respectively.”
To the central one of these ridges Mather and Horton gave (about
1840) the name Trilobite mountain, from the great abundance of
trilobites found here in the rocks of the Lower Oriskany.*

The first paper published in reference to the geology of this region
was by Dr William Horton on the geology of Orange county. Dr
Horton, who was a resident of Craigville, Orange co. and a well

known local geologist, was made one of the assistant geologists of the
first geological district of this State. Dr Horton encountered the
same difficulty in determining the dip of the Trilobite mountain beds
that all later observers have had, namely a tendency to confound
cleavage and bedding. He says that the Trilobite mountain strata —
“repose unconformably upon the Millstone grit (Shawangunk grit)
at the western base of Shawangunk mountain.”? On the next page,
however, he hesitates and says that this southeast dip is “ far from
certain. The stratification is to me still uncertain.”

Several years later, W. W. Mather, geologist in charge of the first
district, published his report where we find that he reached more
definite conclusions. Speaking of the Manlius and Helderbergian
series, he says “ These limestones dip in a west to northwest direc-
tion, lying upon the subjacent Shawangunk rocks conformably ; but
some of the strata are rather enigmatical and appear to dip to the
east-southeast in consequence of the cleavage or shivering of the
strata since their deposition. In some of the strata the real dip is ;
evident, but in others it is not, and it was only after minute examina-
tion that the real direction was with certainty determined.”? |

Dr S. T. Barrett of Port Jervis gave in 1876+ the result of many
years detailed work on the rocks of this region. He correlated the
strata with those farther north and west in New York State, giving
the horizons and thicknesses from bottom to top as follows:

REPORT OF THE STATE PALEONTOLOGIST 1903 1/7

Heinrich Ries in his report on the geology of Orange county,
N. Y.,1 gives a concise description of the successive horizons with a
few fossils from each. He notes the greater prominence of the
cleavage in the higher beds, so that the “bedding is often totally
obliterated.”?

Besides the above, Beecher, Darton and Schuchert have done more
or less work in reference to this region.

This mountain? which represents one limb of an anticline, is a
typical monoclinal ridge of the Appalachian type. It is, however,
not a simple ridge but is made up of many minor ridges, as the

Fig. 2 Complex monoclinal ridge (Rogers)

accompanying ideal figure will show |[fig.2].* All those dipping in
the same direction contribute to the making of the mountain. We
have here, then, what Rogers called a complex monoclinal ridge.*

These minor ridges, locally termed hogbacks, are usually, if not
always, capped by a harder or more resistant stratum than that im-
mediately beneath and are the result of normal erosion. Attacked by
atmospheric agencies and in certain instances at least aided during
present and past times by running water, the weaker stratum is dis-
integrated and washed away. The upper resistant stratum, thus
undermined, breaks off by its own weight and falling, lies as talus
covering the southeast slope of the hogback. The angle of slope of
this talus depends on the size of the fragments. The northwest slope
conforms in a greater or less degree to the dip of the beds.

There is evidence, in a slight development of slickensides etc., of
more or less disturbance in the region, which leads one to suspect
the presence of faults. The great development of hogbacks, which

occur in all horizons but are specially —
characteristic of the Esopus, lends color
to this supposition. These hogbacks,
however, appear to be better explained
as the result of differential erosion, as
noted above. The more or less sudden

rise and dying away of such a ridge in
its northeast-southwest trend is appar-
ently due to the greater or less develop-
ment of certain cleavages; that is, where |
one of the characteristic cleavages at an
angle to the bedding plane is well devel- — |
oped, erosion can most advantageously
attack it.

The present paper gives a report om

the succession of faunas in the strata of

Trilobite mountain, from the Manlius to
the Onondaga formation inclusive. Most

of the field work was done during the
summer of 1902, while the work on the
collections was carried on during the

summer and fall of 1903 in the labora- —

tory of Columbia University. In the
field work, great care was taken to dis=
tinguish between beds of varying lithic
or faunal characters, by keeping separate
the fossils collected from each, even
though such differences were noted in a
bed of less than an inch thick. |

The accompanying map and _ sections

were measured by pacing, and are sub-
ject to correction but in the acquisition

of the fossils great precaution was taken against mixing the collec-

tions from higher or lower beds.

GENERAL DESCRIPTION OF HORIZONS

Manlius limestone

The Manlius limestone is exposed in six of the sections. It is a
very compact, dark blue or almost black rock, containing many black
shale seams. All the beds give evidence of more or less disturbance,
the thin shale layers being at times minutely and irregularly crum-
pled, while the thicker beds, incapable of this minute displacement,
present rather the appearance of little hillocks. Many calcite veins
penetrate the rock mass, specially separating shale seams from the
limestone. Chert occurs as scattered nodules but is not nearly as

abundant as in the higher formations; it seldom gives any evidence

_ of the presence of fossils, and even when deeply weathered it shows

little else than a few crinoid joints.
The greatest thickness, 41 feet, is exposed in section F. The other
sections give exposures varying in thickness from 2 to 31 feet.

Fossils are comparatively rare except in very restricted beds. The

_ most characteristic and abundant species are Spirifer vanux-

cipally because of the restriction of this fossil to the upper beds, the |
Manlius has been separated into an upper and lower portion. The
lower Manlius is exposed in the lower portions of sections E and F;
it contains no fossils that are not likewise found in the upper Man-
lius. The upper Manlius is characterized by the first appearance of |)
such Helderbergian species as Favosites helderbenmeowae ,

and. Fs isip hia e rA.c u's:

Favosites bed! (Lower Coeymans, transitional)

The lithic character of the lower portion of this bed is similar to
that of the Manlius, being a compact, dark blue limestone. The
upper portion, however, is more coarsely crystalline through the
presence of many crinoid joints, being a typical calcarenite.2 The
lower surface of the Favosites bed is, in places, very wavy and un-
even, as though deposited upon an old, water-worn surface. The bed |
is composed almost entirely of heads of Stromatopora and Favosites.
Where weathered, it is specially recognizable by the concentrically
wrinkled laminae of the hydrozoon. At times these heads seem to
have been deposited upon a yielding sediment which in places appears
to be a continuation upwards of the Manlius and extends between
and even partially covers these heads.

The fossils are most abundant by far in the lower third of this 3
foot bed. The most characteristic are Stromatopora COT

such characteristic Manlius forms as Whittieldellam
nucleolata, ostracods (probably. Beyrichia) and Stropitg
eodonta varistriata; the last, however, occurs alsa
the Coeymans proper. With these occur such Helderbergian forms
as Lichenalia torta and Rensselaeria cl. aequyas
radiata. No Gypidula galeata occurs in the Favosites

bed but immediately above it is exceedingly abundant.

of the characteristic and abundant New Scotland fossil, Spirifer
macropleura, was found in these chert-bearing beds and that
Gypidula galeata continues very abundant, it was thought
better to place this in the Coeymans than in the New Scotland
division.

For detailed discussion of this horizon, see sections C, D and F.

New Scotland beds

The New Scotland beds represent an alternation of dense, dark
blue, compact limestone with dark gray shales and thin-bedded sand-
stones. The limestone is at times very full of chert bands which in
places make up almost half of the rock mass. These chert bands,
like many of those in the upper Coeymans are, when weathered, one
mass of fossils. This is a specially good place for the collection of
the more delicate organisms. ‘The arenaceous limestone beds at
times exhibit a succession of light and dark laminae of paperlike
thickness, as at K 15, L 2, and L 3. These thin beds contain either
very few or no fossils except in the very lowest band. An exceed-
ingly rapid change from a comparatively clear to a very black muddy
water condition appears to have made it impossible for life to exist.
Changes of current are also indicated by the appearance of pockets
of coarsely grained limestone in the finely grained at L 3.

This formation is divided into an upper and a lower horizon.
The division is based primarily on the great abundance of S piri-
fer cyclopterus in the upper 125 feet; this is execcdimem
rare in the lower 45 feet. Spirifer macropleura. isso
diagnostic fossil of the New Scotland and is abundant throughout
its whole extent. To the lower New Scotland are apparently con-
fined such forms as Favosites sphaericus and many
bryozoa,e.g. Orthopora rhombifera, O. ree milan
and Monotrypella? abrupta. ‘Fragments of Ememe
and Orbiculoidea occur frequently in calcareous, phosphatic, clay

nodules; no manganese could be detected in these nodules.*

*In the upper New Scotland of western Maryland, .Schuchert notes the
occurrence of manganese-phosphatic nodules similar to those dredged from
the present deep seas, but he does not think these indicate a deep water
condition here, for the “stratigraphic evidence denotes a shallow sea before
and after New Scotland times.” U. S. Nat. Mus. Proc. 26:420.

REPORT OF THE STATE PALEONTOLOGIST 1903 183

Streptelasma strictum is also apparently more abundant
in the lower than in the upper division. The upper beds are char-
Mecerized by the great abundance of Coelospira con-
cava. Common also in the upper beds are Atrypina im-
Me@eata, Stropheodonta becki, Trematospira
Beetaistriata and Cyrtolites expansus. Such
Mameassotropheodonta becki and Strophonella
headleyana are found much more frequently in shale than in
limestone. This is also true of Spirifer macropleura
but does not hold apparently for such species as Delthyris
merlamellosa and Coelospira concava ‘which are

found with equal frequency in shale and in limestone.

Becraft limestone

This is a very dark gray, heavy bedded limestone. The lower
portion is coarsely crystalline, a coarse calcarenite. Most of the
formation, however, is finely crystalline, even at times rather shaly.
A thickness of 16 feet is included in this formation. The lower 2%

also numerous specimens of Edriocrinus pocilliformis

the latter and several other New Scotland species in the Becraft
of northern New Jersey is considered by Weller to be the chief dif-
ference which distinguishes its fauna from that of the preceding
meeesticceedine beds! Gypidula pseudogaleata was
not found in the rest of the formation but owing to the great
abundance of Spirifer concinnus which in great numbers

The other fossils also are those which are specially noticeable in the
Gypidula pseudogaleata beds; yet the entire Becraft

of the New Scotland fauna continues through the Becraft into the |

Port Ewen. Only a few forms, such as Spirifer macro
pleura, unable apparently to live in the slightly purer waters,
disappeared.

Port Ewen beds

The 200 feet included in this formation are mostly concealed.
The few exposures are lithologically very similar to the New Scot-
land, varying from a dark blue limestone to a silicious shale. The
fossils are likewise very similar to those of the New Scotland, in-
cluding such typical forms as Stropheodonta becki,

the transitional character of the Port Ewen to the Oriskany 1s
indicated by the presence of Meristella lata and Spirifer
murchisoni. With the exception of these two fossils) all the
species found in these beds are Helderbergian.

From the close of the Becraft to the uppermost Dalmanites
dentatus beds the fauna is transitional from the typical Helder-
bergian to the Oriskanian. The fauna acquires more and more an
Oriskanian aspect as the beds are ascended. Yet the lower beds con-
tain so many very typical Helderbergian species that there is no
hesitancy in placing these beds in the lower Helderberg. From the
upper 30 feet of these transition beds, however, the above mentioned
Helderbergian species are absent and there is a great increase of the
Oriskanian element. It was thought well, therefore, on account of

the very decided faunal change, to place these upper (D. dentatus)

The development of marginal crenulations and spines on the™

they far outweigh the greater number of Helderbergian species. It
is on this account that these beds have been included in the Oris-
kany. 2

With the inclusion of these beds in the Oriskany the question of
correlation with the Oriskany of other regions at once arises. Are
these lower as well as the upper beds the time equivalent of the
arenaceous Oriskany as developed at Oriskany Falls, New York, or

do they represent in time a part of the unconformity beneath the

normal Oriskany and would, therefore, be an older or lower Oris-
kany?

Large Rensselaerias are characteristic of the typical Oriskany.

type; it is one of the most abundant shells of these beds and is
practically absent from the upper beds and from the Helderbergian

Miclow. Rensselaeria subglobosa is another small and

very abundant non-Helderbergian species confined to these lower
Beds. The following species occurring here are quite typical of
merower Welderberbers: Rensselaeria aequiradiata,
PmereOspira elegans, Stenochisma formosa,
Semermulius vellicatus, Actinopteria textilis and
Homalonotus vanuxemi. None of the following normal
Oriskany species were found here: Rensselaeria ovoides,
Memeetanteris ovalis, Camarotoechia bar-
Mmeti mn teptocoelia flabellites, Spirifer are-
meio cohOonostrophia complanata and Hippa-
meonyx proximus.

With the presence of the forms noticed above which foreshadow
the normal Oriskanian fauna, the presence of a very decided Helder-

Bergian element and the absence of so many typical Oriskanian

_ Species, an earlier fauna than the normal Oriskanian appears to be
indicated. They have, therefore, been called Lower Oriskany.

Upper Oriskany (Spirifer murchisoni zone)

/

The upper Oriskany is characterized by dark blue silicious lime-_
stone and shale, and has an approximate thickness of 150 feet. |
Chert bands occur more or less frequently throughout the entire
formation, but specially in the upper portion. At times these show |
no traces of any fossils even when weathered; at other times they |
are one mass of fossils. Unlike the chert bands of the upper Coey-
mans and Lower New Scotland, these fossiliferous bands apparently
contain.no bryozoa. |

This formation is specially characterized by Spirifer mur- |
chisoni, Meristella lata, Leptoc¢o@itaiamemae
lites, Coelospira dichotoma, “At@pimmopmenaee
textilis arenaria, Diaphorostoma ye mim ueom nan
and Tentaculites elongatus. The lower @pantonmcom
tains an abundance of Orbiculoidea jervisensis. This
large brachiopod is very noticeable, even at quite a distance from the |
exposure, as it occurs frequently at right angles to the bedding.
The most characteristic fossilis Spirifer murchisoni, and

hence the name “ murchisoni zone.”

are present. Omitting from the above all species marked questionable, there
remain 15 characteristic of the Oriskany or later (Onondaga) and 5 of the
Helderbergian. [Safford, J. M. & Schuchert, Charles. The Camden (Tenn.)
Lower Oriskany. Am. Jour. Sci. ser. 4? 7:429-32]

This Camden Oriskany is developed at least as far north as western Mary-
land where, according to Schuchert, the lower portion of the Oriskany
“recalls the Oriskany of Camden, Tennessee, and points to an older stage
than the Oriskany as usually known.’ [Schuchert. On the Lower Devonic
and Ontaric Formations of Maryland, U.S. Nat. Mus. Proc. 26:420]

abnormal in its small size; Spirifer arenosus is one of the |
rarest shells of the New Jersey Oriskany of that region, while
Camarotoechia barrandei is questionably present. ~ |

Instead of deriving an argument in favor of Helderberg-Oriskany |

transition beds from the practical nonoccurrence of the very typical |

larger shells of the normal Oriskany, and from the commingling of |
Helderbergian and Oriskanian species, it is believed with Clarke?
that these beds which are stratigraphically the equivalent of the
Oriskany, represent the calcareous (deep water) facies of the shallow
water original Oriskany. Just as at present much of the older life,
geologically considered, is found in the deeper portions of the sea
so here the Helderbergian types persisted in the deeper water; not |
being able, evidently, to compete with the newer Oriskany fauna, |
they found safety in the less favorable localities, just as the Tn-
sectivores among mammals have persisted to the present, notwith= |
standing their low development, because, added to a maintenance

of small size, they have become nocturnal in habit and in many)
si

ways have adapted themselves to the less desirable localities. |

Large size is usually correlated with an abundance of food. If
the sea the more abundant food supply is in comparatively shallow |
waters. It is here that marine vegetation flourishes, on which all
sea animals primarily depend for food; it is here also that river

borne detritus, which contains a greater or less amount of food, is q

mostly deposited. It would, therefore, be expected that the larger
shells would not be found in the very deep waters i.e. below the
depths at which marine algae flourish. This theory is supported by
the work of Agassiz while associated with the dredging steamer
Blake! In discussing Gastropods and Pelecypods, he thus con-
cludes, “‘ Deep sea dredging has thus afforded few specimens of even
moderately large size, judged by the standard of shallow water or
littoral shells.”

It thus seems well to look on the fauna of these upper Oriskany
beds as existing in deeper portions of the sea at the same time that
the typical Oriskany Falls fauna lived in comparatively shallow

waters. Yet this deeper portion was not removed beyond the reach

of land-derived sediment for the beds are more or less argillaceous
and silicious limestones.

All the large fossils of the original Oriskany noted above as prac-
tically absent from the Port Jervis region, are very abundant at
Becraft mountain? and also, with the exception of Camaro-
mmeemia bartandei, near Rondout N. Y2 But they are
likewise associated in these regions with many Helderbergian forms.
The practical absence of these fossils from the Port Jervis region
can not be due to insufficient time for the migration of the species
into this region, as they occur both south in Maryland, with also
many in Pennsylvania, as well as north in New York State. Nor
can it be due to some barrier since many typical Oriskany forms

Occur here. It may possibly be due to a greater depth of water.

Oriskany-Esopus swamp

This swamp probably rests on the upper beds of the Oriskany,
being worn out of the more easily disintegrated Esopus. The pre-
glacial drainage having been obstructed, this has been filled in to a
depth of probably 20 or 30 feet in places. It is interesting to note
that on Becraft mountain, also, “the contact between the Oriskany

and Esopus is everywhere marked by low, swampy ground and by |

the existence of stream beds.’? |

Esopus

The Esopus is a dark gray silicious shale. It has an approximate —
a

maximum thickness of 550 feet. The very strong cleavage which —

has been induced in it has given rise to very thin, platelike pieces.
The entire Esopus is a continuous succession of hogbacks, giving”
an appearance very similar to a series of step faults. Yet this age 3
pearance may be due merely to differential weathering on account”
of the greater development of certain cleavages over others. This
latter theory is partially borne out by the fact that the valleys

f

between the hogbacks run parallel to the strike of the beds. |
No fossils were found in the Esopus though prolonged search —

was made for them. Irregular pyrite nodules are very abundant in

all parts of the Esopus and Lower Onondaga. For 50 or more feet

up into the Onondaga, probably a fourth of the many fossils found —
are pyritized. This suggests that perhaps each of the Esopus)
nodules*also represents what is left of one or more fossils after the —
wonderful cleavage to which it has been subjected.

The Schoharie grit is here included in the Esopus on account of _

the absence of fossils and the lithic similarity of the two formations,

Onondaga

The transition from the Esopus to the Onondaga is very gradual.
The lowest, much cleaved beds are arenaceous shales and except
for the fossils would be placed in the Esopus. The beds become
more calcareous till 30 feet above the base, a typical calcareous
shale is develoned. Here the fossils are quite numerous though
few in species. The most abundant species are Coelospira

the most abundant fossils are Atrypa reticularis,

Mumeeeeet macrus, Reticularia fimbriata, Pha-

this the rock becomes a heavy limestone with thin shale seams at

intervals. There are thus over 200 feet of the Onondaga laid down

_ before the formation becomes the typical heavy bedded limestone

usually associated with this formation. In the uppermost portion
chert bands make their appearance. ‘This chert is so thoroughly
mixed through the limestone that it has when weathered an exceed-
ingly rough appearance. T’wo hundred and thirty-five feet of the
Onondaga is estimated to be here exposed. White! gives a thick-

Conclusions

From the above it is seen that the Manlius is faunally very similar
in the New York and New Jersey sections but differs in the
Maryland section in that the latter contains many such Coeymans
fossils as the bryozoan Orthopora and brachiopods closely resem-
mee meinuluscampbellanus (Hall)and Gypidula
galeata (Dalman). The latter also contains such Cobleskill
Species as Calymmene camerata Conrad. )

The Coeymans of all the sections is similar in the development of
chert in the middle beds. Sections 1, 3 and 4 agree in having a
basal coral zone while 1, 2, 3 and 4 agree in having the upper beds
Sealy in character, with Gypidula galeata (Dalman)
abundant in the whole of the formation. In Maryland (section 5)
the Stromatopora horizon is at the middle of the Coeymans while
the typical Gypidula galeata does not occur below the
upper beds.

The New Scotland of all the sections is very similar, lithically
weceiaunally, Spirifer macropleura (Conrad) is found
in the whole formation in all the regions with the possible exception
of the lower 20 feet of section 4 and the upper portion of section 2;
Beste latter, Gypidula pseudogaleata (Hall) is also
Present, thus closely resembling the Becraft. Edriocrinus
poOcilliformis Hall occurs in the lower beds of section 5
while it was not found earlier than the Becraft at Trilobite moun-
tain.

202 NEW YORK STATE MUSEUM

The Becraft is a coarsely crystalline limestone (calcarenite) in
sections I, 2 and 3, containing many specimens of Gypidula™
pseudogaleata (Hall) and Spirifer Coneitnaee |
Hall. In section 4 these beds will probably be found in the lower
portion of the covered strata called Port Ewen, as the upper 20 feet of ©
that section, correlated with the Becraft on stratigraphic grounds, ©
are very similar both lithically and faunally to the uppermost New
Scotland of section 3. No Gypidula pseudogaleatam

occurs in the Maryland section but Spirifer concinn tem
does; the latter species is thus found in all the sections, omitting”

section 4. Spirifer macropleura (Conrad) does nom
occur in the Becraft in any section. a

The Port Ewen is not recognized in section 5, and is covered im
section 4. In section I it 1s very similar lithically and faunally tom
the Coeymans, while in sections 2 and 3 it quite closely resembles in : |
like characters the New Scotland.

The Oriskany of all the sections is more or less silicious. Some ~
beds of section 2 and the upper Oriskany of section 5 are more dis-
tinctly sandstones. The fauna of sections 1 and 2 and the upper

beds of 3 and 4 represent the calcareous facies of the normal Orissa
kany.! Sections r and 2 contain many more of the typical shallow ~

water forms than do sections 3 and 4. The lower beds of sections 3, 4
4 and 5 contain an older Oriskany fauna. ‘In the shallowing waters q
of the upper portion of the Oriskany of section 5 there was devel- >
oped the normal Oriskany fauna.

As seen from the above sections, there is an increase in thickness a
of the upper Siluric and the lower Devonic strata from the north to -
the south, indicating a greater subsidence in the latter than in the 7
former regions. These strata thin out westward in New York State, 7
disappearing, with the exception of 7 feet of Manlius? and several |
inches of doubtful Oriskany sandstone, before Buffalo is reached. — .

REPORT OF THE STATE PALEONTOLOGIST 1903 203

One of the most noticeable differences between the upper Siluric
and lower Devonic formations of New York and Maryland is the
greater development of limestones with the corresponding less devel-
opment of shales in the latter region. In Maryland the clear water
condition allowing the deposition of limestone began in the Salina
and was continued almost without interruption to the Oriskany.1
The Manlius fauna entered at the close of the Salina and continued
during a deposit of over a hundred feet of strata; the land was, as
during the Coeymans, at a considerable distance from the present
exposed strata. During at least the upper New Scotland times,
land was not far distant from any of the five sections, but it either
soon sank again or a deflection of currents carried the muddy waters
i another direction, allowing the deposition of the Becraft. In
northwestern New Jersey and eastern New York, this was followed
by a return of the New Scotland conditions, during which the Port
Ewen was laid down.

During the Oriskany the shore line was again nearer, so that the
deposit throughout the whole extent from Becraft mountain to
western Maryland isa silicious limestone. At the close of this period
the land rose both to the south and north. From the middle of
Pennsylvania southward through western Maryland, land conditions
existed, for the Marcellus rests on the eroded Oriskany ;? but in
New Jersey and New York the shore line after remaining near dur-
ing a deposition of from 300 to 500 feet of the arenaceous shales of
the Esopus, again retired to some distance, producing clear water,
during which the heavily bedded Onondaga limestones were depos-
ited. That this submergence took place slowly is indicated by the
very gradual change from the Esopus to the Onondaga.

It is interesting to note that chert is prominently developed in the
Coeymans and New Scotland in each of the five sections, i. e. from
Becraft mountain in eastern New York to western Maryland.

Jersey F. helderbergiae is very abundant in the lowesg

Coeymans. In southern New York a few specimens have been noted

in the upper Manlius.

Among bryozoa the genus Orthopora is recorded by Schuchert
from the upper Manlius of Maryland. This is, according ta

Nickles and Bassler [1900] its earliest appearance. It is next found
in the Helderbergian, where it is abundantly represented in the
upper Coeymans and lower New Scotland of Trilobite mountain.

Gypidula galeata makes its first appearance in the upper
Manlius of western Maryland as a small variety. This is here exe)
ceedingly abundant. It has not been found in the New York or New ©

Jersey Manlius but the normal form appears in great numbers in

the lower Coeymans; it is not present, however, in the Manlius--

Coeymans transition (Favosites bed). r
Leptocoelia flabellites occurs \as a Small yaniciaee

the Becraft of Maryland but not below the upper division of the»

Oriskany at Trilobite mountain.

Beachia suessana appears in the lower Oriskany (Gam
western Maryland as the variety immatura. These basal beds.
are probably contemporaneous with part of the Port Ewen of New
York, since the latter are not recognized in Maryland and there
was a continuous deposition. The first appearance of this species

in New Jersey and New York was in the lower Oriskany.
These species appear to indicate a northward migration.

DETAILED DISCUSSION OF THE STRATA AND FAUNAS OF THE VARIOUS 5)

FORMATIONS AT TRILOBITE MOUNTAIN

Less than one eighth of a mile east of the tollgate which is at
the southwest terminus of Trilobite mountain, is the road leading
along the southeastern foot of the mountain. This may be called
for convenience the Bennett road from the Bennett’s limestone quar-
ries which are situated by its side, and is, as noted om the sketch
map, a public road for about one half the distance. Beyond this it |
is either a rough wood road or a mere foot path. It is along this}

road that the following sections begin, passing northwestward across}

the strike of the beds. The mountain, with the slight exception;

REPORT OF THE STATE PALEONTOLOGIST I903 205

of a few cleared fields, is covered with so dense a growth of shrubs
and small trees that not only is traveling very difficult, but the rock
outcrops are often concealed from view even at the distance of a
few feet. This, together with the fact that most of the strata are
covered with talus or drift, renders impossible the careful notation
of successive beds and their fossil contents which one could wish.
Another peculiarity of the region and one which makes the correla-
tion of beds still more difficult, is the numerous hogbacks for which
the mountain is justly noted. These as already noted are probably
due to 'the greater or less development of certain cleavages over
others, rendering the rock more susceptible to the disintegrating
influences of the weather along the lines of the more pronounced
cleavage. The length of the hogbacks is in the direction of the
strike of the beds. At times when the hogback is very short, a well
developed cleavage may obscure the strike.

The following sections are numbered from southwest to northeast
along the Bennett road, beginning always on the northwest side of
the road.1

Section A

This begins in a small quarry situated about 35 rods northeast of
the junction of the Bennett road with the turnpike. This quarry
was opened in the lower Oriskany since the sandy nature of the
weathered rock renders it available for road material, though not
eminently so.

these latter vary in thickness from a fraction of an inch to an inch
and are very irregular; the thinner ones at times even present an
appearance similar to cranial sutures. The thicker ones are not so
irregular but are rather as though molded over little hillocks. These
shale seams are often separated from the rock above and below by
calcite seams, the crystallization of which is vertical to the bedding
plane; at times even the laminae of the shale are farther separated
thus. There are quite coarsely grained layers, specially toward the

Section F

A few rods northeast of the last section is a large abandoned
quarry in the center of which this section begins.

Fi The Manlius is here separated into an outer and an inner por-
tion by an old quarry floor. It is possible that the outer portion
represents a block of the same rock as the inner, that, undermined by
the larger stream that formerly flowed through this valley, has fallen
to its present position. Such fallen blocks occur % of a mile farther
to the northeast at what is locally known as the Ramapo Hole.

Though this explanation is possible it does not seem probable.
The strike and dip are the same for both portions of this locality.
The fossils also indicate that the rocks are from different horizons.
The outer portion (Fr) has a thickness of 13 feet and is much
weathered. It has the same lithic character as E1. No chert band
was noticed. The following is a detailed subdivision from the base
upward. lower Manlius.

being pyritized, specially the gastropods. This cleaves into much |
larger and broader pieces than in the two preceding localities. The:
cleavage here as in all the Esopus strata is so perfect and continuous -
that it closely resembles bedding. At this locality the bedding is:
seen in the dark colored ribbons about 6 inches in width passing -

parallel to the bedding but is found also scattered irregularly
throughout all the beds. The chert does not occupy a bed to the
exclusion of the limestone, as is usually the case in the New Scot-
Jand and Oriskany, but occurs in very irregular masses through it;
this gives the rock when weathered an exceedingly rough appear- ~
ance and at times it is pitted and amygdaloidat like. This rock is

great decrease in the abundance of Spirifer concinnus and
an entire absence of Nucleospira elegans and Edrio-

Discussion of individual species
HYDROZOA

Stromatopora concentrica? Goldfuss

The organism referred to this species is very abundant in the
Favosites bed.
ACTINOZOA
Blothrophyllum promissum? Hall

Several specimens of a coral very similar to this species were
noticed in the Onondaga formation along the Newburg turnpike.
It was impossible to get any free from the matrix, but the sections
which could be observed had all the appearances of this species.

Enterolasma (Streptelasma) strictum (Hall)

This simple coral is very abundant and always well preserved,
specially in the Coeymans and New Scotland. It is found less
abundantly in the Becraft and Port Ewen. A specimen of average
size measures about 15mm in length by 6mm in width at the large
end.

Zaphrentis roemeri Edwards & Haime

A specimen from the Favosites bed has a greatest diameter of
38mm, It has about 80 septa, most of those in the section reaching
over half way to the center. There are a few shorter ones but no
regular alternation of longer and shorter ones was observable. No
entire specimens were procured so that the length is not known.
This was observed only in the Favosites bed where it was quite
abundant.

The very common coral of the lowest Coeymans, where it
occurs in great abundance. It is found rarely in the upper
Manlius. The fact that it is present in the greatest abund-
ance in the coarsely crystalline beds seems to indicate that
it is a reef species. A specimen from the base of the Coey-
mans shows as greatest diameter of corallites 1.5mm, the average
width being 1.3mm. One section gave 10 tabulae in 7.5mm,
another 12 in 9.5mm, averaging 1 tabula to 1mm. A specimen from

the middle Coeymans gave as greatest diameter of the corallites
I.25mm, the average width was Imm. It gave in one section 12
tabulae in Iomm; in another 18 in 15mm, averaging 114 to Imm.
The wall in both specimens is always twice as thick as the tabulae.
The majority of tabulae on the Coeymans specimen are very
regularly concave with a concavity of from one third to one fifth the |
diameter of the corallite. The specimen from the Favosites bed
shows most of the tabulae flat with only a few concave. A few
tabulae on both specimens are placed obliquely to the walls. There
were faint indications in both specimens when placed in weak acid
for a short time of from one to two rows of pores on the sides of
the cells, usually located about halfway between the tabulae.

mural pores are on the lateral faces of the cells and about midway
between the tabulae. The tabulae are thus as numerous as in
F. helderbergiae. The corallum is lenticular in shape, and
accordingly the only difference between the two species is in the
shape of the corallum.! It was only in the Favosites bed that the
shape of the corallum was observable and this only in cross section.
Here the corallum usually gives, at right angles to the bedding plane,
a round or elongate cross section with the corallites growing in all
directions from a central point. A few, however, were noticed which
had a semicircular cross section with the flat portion lying on the
bedding plane and the corallites growing from the center of the flat
portion. It seems, then, that we have the lenticular, the hemis-
pheric, as well as the spheric shaped corallums in this 3 foot Favo-
sites bed.

It seems to be a question worth considering whether two dis-
tinct species should be based wholly on the form of the colonies of
which the individuals are exactly alike. Might not the shape of the
colonies be determined by the varying conditions of growth? 3

Favosites sphaericus Hall

Found from the Upper Manlius to the Lower New Scotland
inclusive, being specially abundant in the Favosites bed. One speci-
men from the Coeymans measured 12mm in length by 1omm in
width; the tubes averaged a diameter of .3mm with a few as wide
as .5mm. ‘The angles of the walls were quite nodose. On one
specimen from the Upper Manlius the tubes averaged about .2mm
in diameter, while the corallum was 5mm long by 3mm wide at the

incrusting a mass of Stromatopora and being in turn incrusted by it.9

Very small specimens of what appear to be this species are quite
abundant in some of the Upper Manlius beds; but owing to the
great density of the rock, only pieces too fragmentary to be identi-

fied were acquired. |
PELMATOZOA

Edriocrinus pocilliformis Hall

Very abundant in the Becraft where alone it occurs. Only the
‘ bases of this crinoid have been found preserved and the radial plates
could not be made out on them. Those from the shaly limestone are,
as a rule, smaller than those from the heavier beds. The former
average 6mm in the diameter of the summit of the base and 7mm in
length; the latter average 8mm by tomm. The larger species,
E.sacculus Hall, was not noticed in the higher Oriskany beds.

BRYOZOA
Lichenalia torta Hall

Very abundant, but the celluliferous tissue has usually been
removed, leaving only the surface of the epitheca. It was found
quite abundantly in the whole of the Helderbergian with the pos-
sible exception of the New Scotland. It also occurs in the Favo-
sites bed.

Lioclema cellulosum (Hall)

Very abundant in the Coeymans and quite well preserved on the

weathered surfaces of the beds.

L. ponderosum (Hall)

This bryozoan was found only in the lower New Scotland and
there not abundantly.

Monotrypa tabulata Hall

An elongated, spheroidal corallum of this species from the Lower
New Scotland has an average of 20 corrugations on the outer sur-
face of the cell tubes in 5mm, with a diameter for the cell tubes of
about .4mm.

Monotrypella? abrupta (Hall)

One specimen from the Lower New Scotland averages about 10

septa in Imm beyond the abrupt outward turning of the tubes.

REPORT OF THE STATE PALEONTOLOGIST 1903 239

Another specimen from the Lower Oriskany, identified provisionally
with this species, appears to have as many septa before the abrupt
outward bending of the tubes as after it. In this respect it differs
from the type description.?

Orthopora regularis (Hall)

This small species dees not appear to be quite so abundant as the
following one and was found at the same horizon.

0. rhombifera (Hall)

Exceedingly abundant and well preserved in the Coeymans and
Lower New Scotland.

_Unitrypa nervia (Hall)

The most abundant fenestelloid bryozoan in the Coeymans; it does
not differ from the type description. |

U. praecursa (Hall)

Abundant in the Coeymans; it may be a distinct variety since the
margins of the expanded summits of the carinae have simply a row
of nodes; in no instance was there any lengthening of these nodes
noticed so as to form slender bars connecting them with the con-
tiguous carinae as noticed by Professor Hall.?

Vermipora serpuloides Hall

In one specimen, from the Upper New Scotland the tubes have a
diameter of from less than .5mm to .75mm, somewhat less than Pro-
fessor Hall’s description of the type specimen. The tubes are
covered with close, prominent, concentric wrinkles. No longitudinal
striae were noticed. It is quite abundant in the Lower New Scot-
land and much less abundant in the Upper New Scotland.

Many specimens of Lingula and Orbiculoidea occur in phosphatic
nodules in the New Scotland beds. Usually the shell is too crushed

coproliticlike nodules in the rocks of this formation in Albany
county, N. Y. Our specimens agree with his in that they are

“uniformiy elongate or oval in form.”

Orbiculoidea ampla Hall

Rare in the lower Oriskany where alone it was found.

0. jervisensis (Barrett)

The most characteristic shell of the middle Oriskany. It occurs
rather less abundantly in the Lower Oriskany. A noticeable feature

of this species is that it frequently lies at right angles to the bedding

plane.
Pholidops ovata Hali

This little shell is quite abundant on the weathered rock surfaces
of the Upper Coeymans. It is also present in the Lower New Scot-
land. A specimen of average size measures 3.5mm by 3mm.

Leptostrophia oriskania Clarke

Only one specimen was found and that in the Lower Oriskany. It
is smaller than the average given by Clarke? having a length of but
12mm and a width of 14mm. The irregular, concentric wrinkles

can be plainly seen.

Leptaena rhomboidalis ( Wilckens)

Abundant in the whole of the Helderbergian and Lower Oriskany.
The characters of the shell are very constant and hold true to the
type. It is specially abundant in the New Scotland and Becrait.

Stropheodonta becki Hall

Quite abundant in the whole of the Helderbergian, occurring also
in the Upper Oriskanian. It holds quite true to the type description.

somewhat from that of the Manlius. In the Manlius the striae are
strong and usually subequidistant, with from one to several finer
striae between them. A pedicle valve measuring 19 by 27mm showed
very little difference in the strength of the striae but a brachial
valve of about the same size showed it very distinctly, but even here
not so prominently as on the smaller shells. The Coeymans shells
are a little more convex. The coarse striae are less pronounced, while
the finer ones, which vary in number from four to a dozen or more,
are filiform.
8. varistriata var. arata Hall

Sheil very convex with its body covered with angular, coarse
striae; the sides of these as well as the concave area between them
are covered with about six filiform, rather undulate striations. The
umbonal region and the somewhat flattened area at the cardinal
angle show its derivation from the typical Manlius S. varis-
triata, for here the striae are less irregular and the intermediate
area is flattened. It was found not very abundantly in the Coey-
mans and New Scotland. Ley

Strophonella? conradi Hall

The specimens identified with this species are from the Lower
Oriskany. The best preserved one measures 35mm by 40mm, The
one figured by Hall! is somewhat smailer, about 29mm by 37mm.
The shell is uniformly convex, the greatest convexity being at the mid-
dle. It is more coarsely striated than Orthothetes wool-
worthanus, the striae being fine and sharp. These striae on
exfoliation become rounded while the depressions between them are
pitted. (mn another specimen of the same dimensions and similar
striae, the exfoliated striae themselves are very distinctly punctate.
No denticulations were noticed on the cardinal area which is poorly
preserved.

S. headleyana Hall

Only molds of this species were found and these were usually
fragmentary. The pedicle valve is distinctly convex at the umbo,
with a long, broad and rather shallow concavity toward the front.

peal. N. Y. .v.3; pl.16, fig.13-15.

242 NEW YORK STATE MUSEUM

The external molds of the striae are crenulate. It was found in the
Lower and Upper New Scotland and probably in the Becraft.

S. leavenworthana Hall
A single specimen was found and this in the lower part of the Port
Ewen. This is strongly geniculate toward the front of the shell,
while the posterior portion, after a slight depression at the genicula-
tion rises but little over low concentric wrinkles to the umbo.

S. punctulifera (Conrad)

Usually occurs only as external and internal molds. The brachial
valve of this species is deeply concave at the umbo but becomes
strongly geniculate toward the front. The puncta are usually poorly
preserved. It occurs, but in moderate abundance, in the Coeymans,
Upper New Scotland and Port Ewen; one specimen represents it in
the Becraft.

Orthothetes woolworthanus Hall

Hall describes the surface of this as being covered with fine,
rounded striae.1 It is a rare species and is represented in our col-
lection by several specimens from the New Scotland and Becrait.

very finely striated.
C. yandellanus Hall

A pedicle valve about 7mm by 12mm in length and breadth, from
the lower Onondaga was identified with this species. The cardinal
angles are very distinctly flattened. There are about 50 strong,
rounded, radiating striae which are as strongly developed on the
flattened area of the valve at the cardinal angle as on the rest of the
shell. ;
Chonostrophia jervisensis Schuchert

The resupinate character is well preserved in all the specimens.
The striae are narrow with broad, rather flat interspaces where spe-
cially the very numerous and fine concentric markings are noticeable
under a glass. A pedicle and a brachial valve of average size
each measured 7mm by 12mm in length and breadth. This is one
of the most abundant brachiopods of the Lower Oriskany. It is
found more rarely in the Upper Oriskany, while one specimen only
represents it from the Upper New Scotland.

Dalmanella conecinna Hall

Represented in the Port Ewen beds by rather small specimens;
they average 7mm by 6mm. They are often found as internal molds
and one valve is preserved as frequently as the other.

1). perelegans Hall

Quite abundant and well preserved in the Coeymans and Upper

New Scotland.
PD. subcarinata Hall

Abundant, special in the Coeymans, New Scotland and Lower
Oriskany, but is also well represented in the Becraft, Port Ewen,
Upper Oriskany and possibly in the Lower Onondaga. It is thus
seen that this very persistent species thrived equally well in clear
and muddy waters. Specimens of a Dalmanella similar to this
species except in size are quite abundant in the Lower Onondaga.

The largest form observed measured 10.5mm by 13mm in length and
breadth.

Exceedingly common and well preserved in the Coeymans where
it occurs from the base to the summit. It appears suddenly and in

respects they agree with the varietal differences pointed out by

Oriskany measures 23+mm by 15mm, the complete length could not

This shell was called by Dr S. T. Barrett,! on the identification of
Professor Hall, Rensselaeria-mutabilis Hall. But De
Barrett explains that it is much larger than any known before. It
differs from this, however, also in its surface markings and was
hence made into a new species by Dr Weller.2. This is one of the

As seen from the above comparisons and figures,»>*? S. vanu-
xem bears a closer resemblance to S. crispus of Waldron
than it does to the Niagara gorge species. This similarity is spec-
ially noticed in the proportion of length to breadth and in the num-
ber of plications. The Waldron shells are also much more gibbous
and thus approach S. vanuxemi more nearly than’ do the
Niagara gorge specimens. But the cardinal area is much higher
even in the young of all specimens of S. crispus examined
than in any of S. vanuxemi. It is thus seen that while S.
vanuxemi is apparently much more closely related to the
western S. crispus than it is to the eastern, that its possible
derivation from the western species could not have been a direct one.

tions of Columbia University, New York.

In the above brachial valve, the central plication or fold is very
slightly larger than those on each side of it; and the plications are
but slightly wider than the furrows between them. No flattening
of the fold was noticeable. The sinus of the pedicle valve near the
‘umbo is but slightly wider than the furrows on each side, while at
the front of the shell it is about twice as wide. All this is also true

of S. vanuxemst. This young specimen also agrees swam
S. vanwuxemi in the number of plications but exceeds it in the
proportion of length to breadth of the valves. With the exception
of this last fact, the similarity between the two species is almost
perfect and suggests a possible derivation.®

In many of the New Scotland beds occur frequently only the
internal molds*of “SS. cyclopterus. They beameamecenceas
resemblance to S. murchisoni but the cast of the muscula-
ture of the pedicle valve of the former is narrower and the sinus in
it is not as wide as in the latter species. The internal mold of the
plications is also usually less pronounced in the former. The surface
of the mold on both sides of the muscular impression is papillose in
both species, indicating a punctate surface on the corresponding parts
of the shell.

S. cyclopterus occurs very abundantly in the Coeymans
and Upper New Scotland; it is found less frequently in the Lower
New Scotland and Becraft. The Coeymans specimens are more
compressed laterally than the majority of those from the New Scot-
land. ‘The latter ones have the plications more angular also, thus

Sattially approaching S. murchisoni.

Exceedingly abundant in the Becraft. It differs somewhat from

250 NEW YORK STATE MUSEUM

From the above we see that it is only the specimens called by Hall
“large” that have a sufficient number of plications to strictly come |
_ under the species according to his description. Large specimens |
both from Becraft mountain and Trilobite mountain may be placed
in it but the great majority are comparatively small shells with an
average of nine plications on each side of the sinus. Taking the
large shell as the normal, the majority, both at Becraft and Trilobite :
mountains, represent immature development, for the large shells
have passed through this stage as seen by taking younger stages on
them.

In other respects the shells are very similar, they are quite strongly
incurved and gibbous at the umbo, the cardinal area is high, concave
and usually equals the greatest width of the shell. The sinus of the
smaller shells is not as angular as in the larger ones and in this
respect approaches S. cyclopterus. The similarity to this
latter species is more clearly shown in the young. The pedicle valve
of S. concinnus, measuring 6mm by 8mm, has five plications |
anda S.cyclopterus, 5mm by 9mm has four, but in they
latter species the plications are almost as pronounced as in the mature |
shell, while on the former they are exceedingly faint. The con-
vexity of the two shells is very similar. Notwithstanding the close
resemblance of these two species, they can hardly be very closely
related since the characteristic plications of each persist from the

youngest stages.
S. murchisoni Castelnau

Hall! speaks of the great similarity between S. murchisonti
and S. cyclopterus and says that the former may be perhaps
only a variety of the latter “ which in the sandstone attains a larger
size than in the shaly limestone below.” The young of S.
cyclopterus is very like that of. S. murchisoni, mag
of the former having angular cardinal extremities similar to the
latter. The hight and concavity of the cardinal area as well as the
number of plications and the surface markings are also alike. But
there seems to be a slight but constant, greater incurving of the
pedicle valve in the former. Of course with the mature shell there:

Percyvclopterus.
S. murchisoni is abundantly represented in the Port Ewen,

Lower and Upper Oriskany.

Summary of the preceding discussion of the Spirifers

S. vanuxemi may possibly, as far as external characteristics
are concerned, have been derived indirectly from the western species
of S. crispus (orboth from S. petilus ) and has probably
Pave tise to S. cyclopterus.

The young of S. cyclopterus could hardly have becomé
modified into S. concinnus though they are exceedingly
similar, for the finer plications of S. concinnus are present
even on the youngest shell examined.

S.cyclopterus may probably have given riseto S. mur-
chisoni for though the young of all the latter examined have a
less incurving of the pedicle valve than the former, yet there is an
indication of a slightly increased incurving in the younger shells over
the older ones. In all other respects the young are apparently simi-
lar. Hall and Clarke indicate a close relationship between the above
species.2. They place them all under the S. crispus type.

S. arenosus (Conrad)

One specimen from the Upper Oriskany, a mere fragment of a
pedicle valve, is doubtfully referred to this species.

S. macropleura (Conrad)

Exceedingly abundant in the Lower New Scotland and also in
the lower part of the Upper New Scotland. It is found more usually

“The Port Ewen specimens are more or less transitional. They are like
S. murchisoni in having angular plications and a subangular sinus.
They are similar to S. cyclopterus in being usually small and having
rounded cardinal extremities. The convexity of the pedicle valve is inter-
mediate between the two species.

in the shale than in the limestone, e. g. it is questionably present in
the dense blue limestone of K7, while 21 inches higher in K8, a

dark gray shale, it is exceedingly abundant.

S. macrus Hall

Quite abundant in the lower beds of the Onondaga. No perfect
valves were found. One very small specimen with a length of
about 7mm and a width of 2omm has a cardinal area 2mm high and
moderately concave; it has apparently six plications on each side of
the sinus. Another partial pedicle valve, Iomm by 24mm, has nine
plications on each side of the sinus, crossed by many lamellose, con-
centric striae. It looks very much like’ S. mucronatus but
has a very much higher cardinal area. The largest specimen

observed has an apparent width of 4omm.

Delthyris perlamellosa (Hall)

Abundant in the Coeymans and the whole of the New Scotland.
It is very rarely found in the Becraft. This usually occurs in the

same lithologic beds in the New Scotlandas S.macropleura but |

unlike it, an apparently greater vitality enabled it to thrive in pure

waters also.
Reticularia fimbriata (Conrad)

One shell from the lower Onondaga measures 22mm by 35mm by
18mm. The sinus is broad and of medium depth (not quite 2mm).
The fold is quite high toward the front (3.5mm), but fades out be-
fore reaching the umbo. There are five low, rounded plications on
each side of the fold and six on each side of the sinus. The con-
centric lamellae are quite prominent and imbricating toward the
front of the shell. The specimen is much exfoliated but there appears
to be an average of two elongate nodes to Imm of width. Several
specimens of fragmentary Spirifers from the upper portion of the
exposed Onondaga may also belong to this species.

R. modesta (Hall)

This little spirifer is present in our collection only from the Coey-
mans, Lower New Scotland and Upper Oriskany.

REPORT OF THE STATE PALEONTOLOGIST 1903 253

Cyrtina rostrata (Hall)
One entire specimen and two well preserved pedicle valves found

in the Lower Oriskany.

Coelospira acutiplicata (Conrad )
Very abundant in the lowest Onondaga directly above the Esopus-
“Schoharie. An average shell measured 1omm by 12mm by 4mm in
length, breadth and thickness. This frequently occurs in the con-
dition of pyrite casts.
C. coneava Hall

One of the most abundant shells in the whole New Scotland forma-
tion, making up in places the entire rock mass; it is also one of the
most characteristic species of the Port Ewen and is likewise well
represented in the Coeymans. One brachial valve, 6mm by 7mm in
length and breadth, from the Onondaga, seems to be identical with

this species.
C. dichotoma Hall

Almost as abundant in the Upper Oriskany as L. flabel-

mates. 3
C. grabaui sp. n.

Shell subovate in outline; marked by 9 plications on each valve.

These plications are moderately prominent, and broadly rounded

near the front of the shell, decreasing in strength toward the cardi-
nal extremities. The median depression of the pedicle valve is
very deep from the center of the valve to the front, and contains a
single plication which fades away toward the front. This produces
a correspondingly accentuated elevation on the anterior portion of
the brachial valve which has a strong depression down the center,
thus forming two median plications, which, however, become
merged into one at the front of the shell, The fold disappears at

254 NEW YORK STATE MUSEUM

the middle of the valve and from there to the hinge the valve is flat. |
In the oldest portion of the shell, i. e. from the beak to about one
half the distance to the front, both valves present the appearance of :
a typical C. acutiplicata (Con.). But from this point to the|

front the valves grow rapidly toward each other, thus producing a

very conspicuous thickening of the shell. With this thickening

there is an increased prominence of the concentric lamellae. The

dimensions of a large specimen are: length, 12mm; breadth, 16mm;

thickness, 9mm.

This species which is from the very lowest Onondaga, immedi- |
ately above the Esopus-Schoharie, evidently represents an offshoot !
of C. acutiplicata which, rapidly accentuating certain char-
acters, soon became extinct, for it was not found in any higher beds. |

{

It must be regarded as a phylogerontic type, in which the characters |
normal in the adult of its ancestors are lost in its own ephebic stage. |
Figured specimen, paleontologic collection, Columbia University, |

catalogue no. 19,326.

Leptocoelia flabellites (Conrad)

One of the most characteristic Upper Oriskany species, and occurs -

also less abundantly in the middle Oriskany.
Whitfieldella? nucleolata (Hall)

Very abundant in the Upper Manlius. The shell is small, an
average one measuring 6mm by 5mm by 3mm in length, width and -
thickness respectively. It is not noticed in the Lower Manlius, while |
several specimens of the average size were found in the Favosites

bed.
Trematospira multistriata Hall

Abundant in the Upper New Scotland; it does not vary from the |

description of the type.
T. perforata? Hall

Several external molds and an internal mold of the pedicle valve

from the Upper New Scotland present the characters of this species.

Nucleospira concentrica? Hall
In the Lower New Scotland are many specimens of a shell which
in external characters comes nearest this species but differs from it

in the absence of a central, longitudinal, depressed line of the dorsal
valve and in the fact that the dorsal valve is not depressed at the |

is

beak. The average shell measures 14mm by 14mm by 6mm. The

REPORT OF THE STATE PALEONTOLOGIST I903 255

pedicle valve is convex, specially in the middle toward the beak.
The brachial valve is most convex at the beak. One or two strong,
‘concentric growth lines are usually present on each valve.

N. elegans Hall
Quite abundant in the Becraft and Lower Oriskany. A shell
slightly above the average in size measures I5mm by 17mm by 8mm
in length, breadth and thickness respectively.

N. ventricosa Hall

Rather poorly preserved and not abundantly represented in the

‘Coeymans.
Meristella laevis (Vanuxem)

One of the most abundant Helderbergian species, occurring usu-
ally as perfect shells but often as internal molds. It is very abundant
from the Coeymans to the Becraft inclusive.

M. lata Hall
Very abundant, specially in the Upper Oriskany. It occurs as

f

|

frequently in the form of internal molds as in that of perfect shells.
Ina large shell of this species, the length of the striated portion of
the internal mold of the muscle impress was 27mm. This was the
largest specimen found. ‘This species is also present in the Port
‘Ewen. —

_ The Meristella sp. of the Upper New Scotland L2 and L3
is a shell alrhost as broad as M. lata.

M. princeps Hall

__ Few specimens found but usually well preserved. One specimen
“was noted in the Lower New Scotland and several in the Becraft.

PELECYPODA

Pterinea? gebhardi (Conrad) var.

One large specimen from the Upper Oriskany agrees with this
‘Species in size and in the broad and not prominent radiating ribs.
The grooves between the ribs have comparatively faint and narrow
Tays. The ribs themselves are very broad and are longitudinally
| striated, while the whole shell has rather faint concentric ridges,

placed about 1.5mm apart on the main part of the shell but crowded |
as they curve around the anterior ear. The posterior ear is not |
preserved but was apparently much larger than the anterior one. |
On the ventral part of the shell the primary ribs increase in width

anteroposteriorly from 7g to +¢inch while the grooves increase but |

slightly in breadth.
P.? naviformis (Conrad)

One well preserved left valve from the Coeymans has all the |

characteristics of this species. Hall cites it from the Pentamerus |

‘imestone, whether lower or upper he does not say.t

Megambonia aviculoidea Hall

Owing to the coarsely crystalline character of these shells, they |
are seldom sufficiently well preserved to admit of identification for |
the rock on breaking fractures more easily through than around |

them. It is apparently quite abundant in the Upper Manlius.

Actinopteria communis ( Hall)

The specimens identified with this species have rounded radiating |
ribs and are not nodose. One quite well preserved specimen was |

found in the Lower New Scotland.

A. textilis (Hall)

Very abundant in the Lower Oriskany. The surface has strong

radiating ribs which at the base are distant from one another about —
three times their width. In the middle of each intermediate space —

is a finer radiating ray. Concentric ridges give a cancelated appear-

ance to the entire surface. The large specimens from here are of a)

size similar to those termed small by Professor Hall.2 A compara-
tively large specimen was 30mm long from tip to tip of ears and
32mm in greatest length from the hinge to the front of the shell.

A. textilis var. arenaria (Hall)
This differs from the above merely in having the concentric ridges
accentuated, becoming imbricating lamellae and spinose where they

found rarely in the Lower and abundantly in the Upper Oriskany.

Cypricardinia lamellosa Hall
One rather small but quite well preserved specimen from the lower

part of the Port Ewen.
GASTROPODA

Platyceras cf. gibbosum Hall
The specimen from the Lower New Scotland identified pro-
visionally with this species agrees with it in shape and size of
volutions. It is, however, much less strongly plicate.

P. lamellosum [fall
One specimen from the Upper Oriskany agrees exactly with Hall’s

figures and description! in size and shape. It preserves, however, no

surface markings.
P. platystoma Hall

Two specimens from the Lower Oriskany answer to the descrip-
tion of this species.2, They measure 35mm by 40mm and 30mm by
35mm respectively ; the first measurement in each case is the diam-
eter of the aperture at right angles to the breadth of the shell, the
other is the distance in a straight-line from the posterior end of the

“apex to the anterior side of the aperture. Each has three broad
rounded plications on one side, the other being mutilated.
P. reflexum? Hall
Two rather poorly preserved specimens from the Middle and
Upper Oriskany are questionably referred to this species.
P. tenuiliratum Hall
One well preserved specimen from the Lower New Scotland.
P. ventricosum Conrad

One small specimen, gmm in greatest length, from the Upper New

‘Scotland and one 30mm in greatest length from the Lower Oriskany.

dence of several rather prominent transverse folds. The spiral por- |
tion of the shell is not preserved.

Diaphorostoma desmatum Clarke

One shell from the Upper Oriskany has three volutions; its
diameter through the plane of coiling is 17mm, the greatest dis-
tance at right angles to this plane is Iomm. ‘The concentric striae
are pronounced and closely crowded. The revolving striae do not
cross the concentric ones and hence only modify the interspaces.
This is very similar to the young stages of D. lineatum of |
the Onondaga and Hamilton above. On the adult shell of this latter
species, however, the revolving striae become more and more pro-
nounced, producing a cancelation; in the older shells the difference
in the development of the two sets of striae becomes still more
marked, and the cancelation becoming scarcely noticeable, the shell
appears at a glance to be only longitudinally striated, the very oppo-
siteof D. desmatum.

D. nearpassi (Weller)

One small specimen was found in the Lower Oriskany. It is 8mm
in greatest diameter and 4mm high. The lines of growth are
crowded and raised above the surface of the shell. No revolving
striae are present.

D. ventricosum (Conrad)

Shell normal in size and form. It is very abundant in the upper |
beds of the Oriskany where it almost invariably occurs as internal
molds. It also occurs rarely in the Lower Oriskany beds and in the |
Lower New Scotland.

PTEROPODA

Tentaculites acula Hall

The characteristic pteropod of the Lower Oriskany where it is
quite abundant. ;
T. elongatus Hall

Exceedingly abundant in some bands of the Upper Oriskany. It |
occurs much more rarely in the Lower Oriskany while one specimen _ |
was noted in the Upper New Scotland.

REPORT OF THE STATE PALEONTOLOGIST 1903 259

T. gyracanthus (Eaton)

This very characteristic Manlius fossil is very abundant both in the
lower and upper portions of this formation. In one or two narrow
zones of the Upper Manlius it practically occupies the bed to the
exclusion of all else. The shell is normal in its development.

Conularia pyramidalis var. jervisensis n. var.

The specimens identified with this species are from the Upper
Oriskany. They agree fully with Hall’s original description of
those from the shaly Helderbergian beds below, with the exception
_ that on our shells the transverse striae are twice as numerous as on
the typical species. Near the apex there are 20 striae to three lines
while on the rest of the shell there are 30. Hall+ gives 15 or 16 in
three lines but says that at intervals near the aperture they are some-
times more crowded. Here the crowding has become the normal
condition. ‘The dimensions of a specimen incomplete posteriorly are
22mm in length, 9 mm in width at aperture.

CEPHALOPODA
Cyrtolites? expansus Hall

Five or possibly six specimens from the Upper New Scotland are
all smaller than those described by Professor Hall.2 The largest
measures 15mm by 11mm by 16mm in width and length at aperture
and length from apex to anterior portion of aperture respectively.
The carination is quite prominent and two of the specimens show
concentric striae. Only one specimen gives indication of a broadly
expanded aperture.

Orthoceras helderbergiae? Hall
The internal mold from the Coeymans identified provisionally with
this species agrees closely with the short description given by Pro-
fessor Hall.?

. Grammysia sp. nov.

One imperfect specimen of a Grammysia from the Trilobite ledge
(Lower Oriskany) indicates a close relationship to G. undata of
‘the Chemung group. It agrees with it in size and surface markings
as far as these are preserved but differs from that species in that the
hinge line anterior to the umbone has a greater extension and that
‘the convexity of the shell posterior to the cincture is decidedly

' Shell outline characterized specially by an abrupt downward
“curving to the hinge line posterior to the beak and by an oblique

‘truncation anterior to the hinge line, as well as by the navicular
curve of the base. Beaks separated by an area of medium width.
‘Dentition taxodont, apparently multivincular. Anterior to the
‘beak is a radial buttress! extending from the hinge line downward
and slightly forward about one third of the distance to the base of
the shell. The internal molds from which this description is made
show on the umbone a slight depression running parallel to the
fadial buttress. An undefined sinus gradually broadening extends
| from the hinge line to the posterior basal extremity.
_ Three specimens measure in length and hight respectively, Igmm
by 8mm, 20mm by 12mm (imperfect), 16mm by tomm (imperfect).
|) This species, which is from the Upper Oriskany, more closely re-
| Biribies i external characters Clidophorus cuneatus
| Hall of the Upper Ordovician? than any other species with whose
description we are familiar. It differs specially, however, from
/C. cuneatus in being more elongate in proportion to its hight,
in the more central location of the beaks and in the abrupt down-
ward curving to the hinge line posterior to the beak.

*On comparing the radial buttress of this species with that of Mach-
jaera costata, a recent shell abundant along the whole New Eng-
, land coast, we note that in the latter species it is perpendicular to the shell
| and also is narrowest at the hinge line, increasing in breadth as it fades
(away, in this respect being just contrary to Nuculites barretti.

CONTRIBUTIONS TO THE FAUNA OF THE CHAZY LIME-
STONE ON VALCOUR ISLAND, LAKE CHAMPLAIN

BY GEORGE H. HUDSON, VICE PRINCIPAL STATE NORMAL AND TRAINING
SCHOOL, PLATTSBURG N. Y.

The following descriptions have been made in order to facilitate the study
ef a section in the Chazy rocks on Valcour island. All the species were
obtained from the beds of this section.

CYSTOIDEA
Genus MALOCYSTITES Billings
Malocystites emmonsi sp. nov.
Plate 1, figures 3-7

Description. Viewed from above along an axis determined by the
point of attachment to the stem and the center of the more globular
portion of the theca, and with the food grooves or what I may call
the sigma, turned away from the observer, the anus appears to be
placed a little to the left and more or less in advance of the summit;
this axis measures from 6 to 10 mm. Viewed from the right side,
that portion of the theca bearing the rather prominent plates of
the sigma is seen to be produced so as to form a distinct and some-
what contracted neck with the mouth from 40 to 80 degrees in ad-
vance of the distal end of the axis as defined above; the edge of
the theca from base to anterior food groove is much flattened form-
ing in most cases a rather straight line or chord of from 90 to 140
degrees; the posterior edge is also rather straight or but slightly
convex, forming a chord of some 45 degrees from base; from here
the outline is usually well rounded to neck under edge of posterior
food groove, though some specimens are rather obliquely oval or
subovate in outline; the longest diameter is from base to outer edge
of posterior food groove and is from one fifth to one fourth longer
than the measured vertical diameter. There are on an average some
43 plates in all, not counting the covering pieces, and their outlines
usually vary from tetragonal to heptagonal. Some of the specimens

REPORT OF THE STATE PALEONTOLOGIST I903 271

are in part ornamented with fine regular, rounded, and not crowded

granulations, while in others the raised granulations become quite

_ irregular in outline and often confluent. The larger plates have each
a more or less prominent umbo, which may be central or excentric
and which together give various angular outlines to different por-
tions of the theca; there is usually a very large umbo between the
anus and the base. More or less wide, raised ridges usually connect
the umbones and many finer ridges run from them over the plate,
branch, cross the sutures and form some very fine reticulations hay-
ing rounded, depressed pits between them.

Observations. This species differs from M. barrand1ii in its
much smaller size, the excentric position of the anus, the outgrowth
of the theca to form a neck under the sigma, its conical base, its.
prominent umbones and varied angular outlines. Mr Percy E. Ray-
mond writes me that the food grooves in the type specimens of M .
barrandii are not so much elevated in proportion to the size of
the theca as in this Valcour form.

These specimens are so well preserved that it seems proper to
make their description still more complete. Specimen A, which has
been chosen as the type, still bears two rings of the stem and shows
it to have had a marked and permanent bend toward the posterior
side. Another specimen has six rings of the stem still attached;
these are circular, measure I.2 mm across next to the theca and
uniformly taper down to .g mm without alternations in size. The
outer surface of the joints is only gently convex and each joint is
very faintly anc closely ribbed across its edge; there are about six
rings to the millimeter; here also a rather abrupt bend toward the
posterior side occurs next the theca and it is rather difficult to dis-
tinguish the sutures between the first two or three rings; the lumen
is round and about half the diameter of the ring. The stem appears
to have been short and used perhaps as an anchor but not for com-
plete support. The theca probably rested, in part at least, on the
plates to the posterior of the proximal ring. This position would
place the mouth at the summit of the theca and bring the arms into
a horizontal plane and a similar external environment. Figures 4,
6 and 7, plate 1, show three specimens oriented as if supported by

272 NEW YORK STATE MUSEUM

the stem alone, making the axis chosen for description the vertical
axis on the plate. A glance at figure 7 will perhaps show the

absurdity of considering this a normal position, particularly so if |

the sigma plates bore spreading brachioles, as their structure sug-
gests. The posterior arm is usually the shorter and less developed,

the difference in environment caused by the position of the anus _

being the probable cause.t

The plates of the type specimen, designated as A [pl. 1, fig. 3, 4]
are arranged as follows. There are three basal plates, the anterior
of which is about half the size of the others. ‘This plate is in contact
with but two plates lying above it, while each of the other two is in
contact with four plates above. Numbering to the right from the
posterior margin, plate 4 rests on the upper left side of plate 1, this
plate and the next are tetragonal and small; no. 6 is heptagonal,
large, and has a prominent and excentric umbo a little above and to
the right of the center; plates 7 to 9 are nearly as large as 6, are

*I have for some years harbored a notion that one of the many laws under-
lying the production of variation and new species might be expressed by the
term, “the survival of the unfit,” perhaps better stated as “the survival of
the weak,’ a law related to Cope’s “law of the unspecialized.” Failure

to divide normally at the proper time gave cell aggregates and inaugurated ©

a new wave in what Herbert Spencer points out as the law of rhythm in
evolution. No new crest of strength springs from the crest of the last wave
but each crest is preceded by a trough. The invagination of a weak hollow
sphere of cells gave rise to the gastrula and forced a division of labor on
the “unfortunate” aggregate; and this law, if I may so call it, offers sug-
gestions as to the origin of many things from cell conjugation to the dis-
covery of some weak mortal that he might make the pen mightier than the
sword he was unable to use. The idea suggested a possible cause for the later
change in shape of Eunema epitome. Lyriocrinus? beecheri,
with its invaginated base produced at first by the yielding of weak basals
to the persistent attack of gravity, is an illustration in point and an extreme
is found in Blastoidocrinus carchariidens. ‘Thee talmeman
plates to support increased weight has initiated variation along this line in
many crinoids and natural selection has found certain mechanical advantages
in the new forms; out of weakness has come strength. The law suggests
that ancestors of Malocystites were once supported by the stem alone and
had their arms in a normal position, but that descendants with weak stems
often found themselves let down to the ocean floor and had to make shift
to live under adverse conditions. Increased growth of the posterior plates
or decreased growth of the anterior plates would have brought the arms
again uppermost and given rise to a form like that here shown. A stem
unused for support might become of advantage as an organ of locomotion
and secure slow changes in position.

hexagonal, and have slightly raised centers; plate 10 is the last to
have a side in contact with any of the basal plates, it is pentagonal
and about the size of no. 7. Plate 11 is a large pentagonal plate and
may be considered as the first in the third row, though it is so wedged

in between plates 10 and 4 as to have its lowest angle touch the
highest angle of plate 1; the center of this plate lies a little to the
right of a line drawn from anus to base and is the lowest of three

that might be called the anal row. Passing still to the right, no. 12

is the largest of the remaining plates with one exception, is hep-
tagonal, and bears a moderate umbo. Plate 13 supports the fifth and
the following brachials (if I may so call these plates) of the anterior
arm; plate 14 supports the third brachial of this arm and also half

of the second and nearly all of the fourth brachial. The latter arm _
plate has a small shoulder against no. 13. Plate 14 is marked by a |
prominent ridge connecting with the umbo on plate 6 and the place
of meeting of plates 13, 6 and 14 is depressed. Plate 15 supports

shoulder against the first brachial and supports also the plate bearing
the genital pore. The plates now leave the arm, 17 is moderately
large, hexagonal and with a slight umbo just above its center; 18
is small and tetragonal; 19 is as large as any of the others, is hex-
agonal and has a very prominent and nearly central umbo; this
completes the third row and is the last of the plates bearing umbones.

lower border of the anus; plates 22 and 23 form the right and a
portion of the upper border of the anus, and 23 also supports the
first and half the second brachial of the posterior arm. Plate 24 is
just anterior to and also supports the first brachial of this arm, it
also reaches the mouth and forms part of its border; plate 25 is
semicircular in outline, fills up the inner portion of the half sigma
of the anterior arm and supports all of its brachials on this side; its
inner border is raised to form the edge of a channel which receives
the eight grooves of the anterior brachials. Plate 26 borders on the
mouth, supports the posterior edge of the first anterior brachial, and
bears the genital pore; 27 is formed like 25 and receives the six
grooves of the posterior arm; 28 supports the last brachials of the
posterior arm on the outer side of the curve and with 29 forms the
left border of the anus. At the point where plates 26, 27 and 28
meet each other there is a peculiar, small, roughened mound which
may represent the madreporite.

There is considerable variation in the plate arrangement in the
three specimens figured. Specimen C was probably as aberrant a
form as could have been found in the two hundred or more speci-
mens collected. This specimen has 37 plates besides the brachials,
A had 29, and B shows but 281 The four plates bordering the
mouth are constant and may be called the orals. They bear cover-
ing plates some of which may be seen in specimen B [pl. 1, fig. 5].
The plates I have called brachials are vertical plates with their lower
edges resting on the neck plates of the theca and their middle por-
tion against the opposite oral. These plates do not show covering
pieces but the orals numbered 25 and 27 still continue their cover-
ing pieces which now reach completely across the food groove, form-
ing a single series of rectangular plates. There were several of these
in position on the anterior arm but they became lost through an
accident and the only completely transverse plates now present are
in the posterior arm. The first one or two brachials are the largest;
the others then grow rapidly smaller as the half sigma recedes from
the mouth. All bear truncate faces on their distal ends and the
larger. are marked as if they had borne extended and movable
brachioles. The larger faces are directed more nearly upward and

plate. Surrounding all is a well rounded but not prominent ridge.
The smallest plates seem to have had short extensions which were :
bent below the horizon of the sigma. Going toward the larger plates |
the angle of each truncate face gradually changes till we reach the |

larger and more vertical brachioles. The normal specimens have six

grooves running into the posterior portion of the sigma and eight |
"into the anterior portion, but it is difficult to determine whether these |
grooves represent so many separate plates. The last two are very !
small and I have as yet been unable to detect a suture between them. |

Specimen © has. but 10 radiating grooves in the complete sigma,
five in each half. Specimen B seems to have no genital pore and the
ornamentation of the plates varies considerably from that of A. ‘The
position of the madreporite is constant in all.

The anus is large, usually appearing as a rounded pentagon. The
covering plates in some of the specimens seem to have been pressed
into the anal opening ;.one specimen has the plates in position and
they form a gently convex mound, the plates meeting so exactly that
the determination of their number, whether five or six, 1s no easy
matter. They are ornamented by radiating lines of exceedingly
fine and close tubercles.

The specimens so far examined have each six neck plates, but
there is much variation in their manner of supporting the plates of
the sigma. The three basals seem to be constant with no. 2 always
the smaller. ‘The plate numbered 7 seems also constant in shape and
position and the two plates directly above it always reach and sup-
port the sigma plates above them. In the figures illustrating the cup
dissections I have crudely indicated the more marked umbones and
the more prominent ridges connecting the same. Further study
would no doubt enable one to designate many more of these plates
as constants. The specific inheritance had not become as yet so
fixed as to completely shut out some of the plates of an older inherit-
ance. ‘The anterior plates were evidently less disturbed in their early
growth and so have more nearly a constant shape. Name given in
honor of Dr Ebenezer Emmons, former state geologist of New York.

Description. Cup small, but 6mm from base to upper angle of
primaxil [tAx], while the whole crown from base to top of incurved
arms is 21mm; the cup has been crushed and thus slightly widened,
but the greatest width still measures but little over 7mm. Proximal
joint of column round and sunken in a hollow base formed by a
strong infolding of the proximal portion of the basals; column next

the cup formed of alternate narrow and wider rings. The basals

appear to be hexagonal and each is marked by two very prominent

keels running from the central portion of the plate toward the lower
angles. Both are bent, with the convex side toward the ring; at
their junction near the center of the plate they give rise to a short
vertical fold which soon divides into two less prominent keels or

ridges which pass outward to the radials; between the former and
the latter are three faint folds, seen best next the edge of the plate
and perpendicular to this edge; there is also a strong transverse
ridge below and parallel with the truncate upper edge of the plate.
The pentagonal, completely separated radials carry very slightly

raised ridges continued from the basals; those near and parallel with —

the lateral margins are the more prominent and extend vertically

over the brachials at about one fourth the width of the plates from
their margins, as fine, raised ridges; these fork near the upper edge
of IBr (first primibrach), and again just as they leave the IAx; the
outer branch in each case remains the stronger but becomes very
faint on I1Br,. The first secundibrach (IIBr,) is about twice as wide
as high and the pentagonal IAx presents approximately the same
area of surface. These plates seem to be ornamented only by what
appear to be faint nerve ridges and their branches which present
scme very faint reticulations. No ray seems to have possessed a
plate between IBr, and JAx. Each interradius has one large plate
in contact with the basals, and six or seven plates in addition, one
of which may be as large or slightly larger than the first; directly
over these the pinnules from IIBr,, with

their plates somewhat enlarged, meet each SNC :
other and are incorporated in the cup. The [ a
IO arms, thus brought closely together, are { ?
comparatively large, biserial and, with their i S
pinnules, obovate in outline; the IIBr 7

extremely graceful. This folding is a mixture of the convolute and
imbricate and is shown in figure 5.

Observations. The crushed condition of the cup has made the
determination of the arrangement of the plates of the interradii a
somewhat difficult matter. In my drawing of this plate arrangement
(fig. 4), I have outlined only such plates as were present and in,
or nearly in, their normal position. In one or two instances a frac-
ture may have been taken for a suture. The complete interradius
to the right in the cut was drawn from plates crushed in just below
the first incorporated pinnules and perhaps should have one or two
additional small plates near the latter. The completed interradius
placed in the position of 1. anterior IR apparently has had its basal,
the top of which is broken across, forced to one side. This inter-

280 NEW YORK STATE MUSEUM

radius seems to possess two or more very small tetragonal plates
lying between but not belonging to the enlarged pinnules from IIBr, ;
it should perhaps have been chosen to represent posterior IR. Owing
to the condition of uncertainty I have refrained from completing
the diagram and have made the left hand interradius of figure 1
[pl. 3] the vertical one in figure 4 of this text.

I am one of a host whom Prof. C. E. Beecher placed under lasting
obligation through his kindly given and generous help. This speci-
men was found soon after his visit to my camp in the summer of
1903 and [ name it after him, not alone in recognition of the eminent
position he attained in the science to which he gave his life’s labor,
but also as a token of personal affection and in appreciation of many
rare mental qualities which I came to see as one can best see such
things through the freedom of field work by day and at the open
camp fire by night.

Genus RHAPHANOCRINUS \Vachsmuth and Springer

Rhaphanocrinus gemmeus sp. nov.
Plate 2, figures 1-5
Description. Cup small; its hight measured from proximal
surface of basals to distal angle of first secundibrach 7.5mm; its
diameter measured from upper edge of right posterior primaxil
about 9.6mm; that of its base across lower shoulders of basals
4mm; that of proximal ring of stem 3.3mm; sides of cup from
lower edge of basals to top of radials rather straight and
from this point gradually curving to give a somewhat ver-
tical edge to cup at IIB,. The more or less narrow depressed
margin of the plates is ornamented by numerous fine radiating lines
which cross the sutures; a single large proximal interbrachial pos-
sesses more than 40 of these lines, and under a low power they are
seen to be rows of fine tubercles; from the inner edge of this border
the plates rise rather abruptly to the hight of about .5mm and
become smooth or microscopically granular with a large flat or
slightly concave area which shows, near its outline, a marked ten-

dency toward suppression of the plate angles. The infrabasals are .

small and almost completely covered by the proximal ring of the

REPORT OF THE STATE PALEONTOLOGIST 1903 281

stem. Near the cup the stem is made up of alternating light and
heavy rings, slightly flattened on their radial edges and possessing
radially disposed sutures. The basal plates are largest and are trans-
versely depressed as if slightly bent outward at their bases or as if
impressed with a quadrangular die that left four shallow pits at its
four corners. The radials are next in size, their raised areas are
nearly circular in outline and about 2mm in diameter; they also
show slight traces of lateral impressions similar to those on the
basals; the raised areas on these plates and on the basals are so
large as to nearly or fully meet at the plate
edges midway between the angles. The first
brachials are smaller and their raised surface
wider than high, this area showing a tendency
to become diamond-shaped; the plates of the
radii above these brachials are well rounded
and smooth save for a single depression shown
my the anterior and right anterolateral
primaxils. The proximal interbrachials are
but little smaller than the basals and _ their
taised areas are more angular in outline and
well separated from those of the adjoining
plates; each supports two smaller plates and
these in turn three others above them; a few
smaller plates above the latter lose the smooth
rounded subcentral elevations and present but

terior interradius there is an extra plate im-
mediately above the anal which is followed
by a vertical row of seven and perhaps more smaller regular
hexagonal plates. The anal tube is about 2.3mm in diameter; rises
with a slightly broader base, from a position but little posterior to
the center of the oral surface; is bent down just above the ninth
hexagonal plate of the anal row; curves slightly to the right and
then back to the left and its tip nearly touches the IIBr, of the
anterior R; the last part, 4mm in length, consists of about 10 rows

of plates each .4mm long and the row so twisted as to bring a plate

of one row directly under a plate of the next! Some pinnules appear
to have been incorporated in the lower portions of the tube. Arms
above the IIBr, are wanting in the specimen. Intersecundibrachs
present.

Description. Cup small, its hight from base to level of upper
edge of anal x, 6.5mm, its width measured across from base of left

Fig. 7 Analysisof Carabocrinus geometricus. The outline of the radials is drawn
as viewed from the side and the true outline of the oral edges is not seen. The more easily
detected axial folds have been shown by shaded lines.

posterior IAX 7.5mm, its width half way between base and last
measured diameter 6.5mm, subhemispheric with a slight vertical

elangation and a tendency to show inversely conical outlines along

the lines from base through the centers of the RR, particularly in the
1. posterior R where the flattening of the side of the cup is well
marked. Vertical diameter of the IBB a little less than that of the
RR and their transverse diameters about one half of the latter; the
IB of |. posterior R is a little larger than the others and pentagonal,
one shoulder supporting the supplemental anal plate, the others are
all tetragonal; the IB of r. posterior R is smaller than the others.
The vertical and lateral diameters of the BB are about equal to the

*It will be seen that such a twist, if I may so call it, could be described
as turning either to the right or to the left, or one might consider the tube

to be formed of about 20 longitudinal rows of plates without “twist” but -

REPORT OF THE STATE PALEONTOLOGIST 1903 283

width of the RR; the B of R posterior IR is heptagonal, the other
four are hexagonal. The plates of the anal row are pentagonal, the
anal x is about two thirds of the width of the RR on either side of
it, its vertical diameter is the same, one edge is uppermost and the
two vertical edges are nearly parallel; the radianal is a little smaller
with one angle uppermost and its sides of very nearly the same
length; the supplemental plate is slightly smaller still, of nearly the
shape of the anal x and with an angle down. The RR have raised
centers and the axial folds of these plates pass across the sutures and
over the neighboring plates after the manner of C. radiatus,
but the folds are finer and less prominent. The plates are very
faintly tuberculate, the tubercles showing rather more plainly along
the upper edges of the axial folds. The first Br is also the IAX, it
is pentagonal, stout, nearly or quite half the width of the R, and
well rounded on the back; the hight of the outer edges is about one
fourth of the width of the plate.

A very small portion of the tegmen is present in posterior IR;
the relative size and position of the plates will be seen in plate 1,
figure 2. At each of the other four junctions of the RR in the
periphery of the tegmen there is a shallow excavation of the plate
margins, forming a straight base and an acute angle at either end
as if cut for a dovetail. This appearance suggests triangular del-
toids with a bordering plate on either edge, but as I am not familiar
with the tegmen of crinoids and do not have easy access to the litera-
ture of the subject I shall refrain from further suggestion.

Attached superficially to the left edge of 1. posterior R there
appears to be an anal pyramid of five plates which may belong to
this species, and I have been careful to leave it on the specimen,
though as the locality abounds in crinoid fragments its mere prox-
imity should not be given undue weight. The apex of the pyramid
shows a very small starlike opening, each plate having a more or
less pointed tip and failing to meet its neighboring plates near the
apex.

Three rings of the stem are still attached to the cup and seem to
be rather uniform in size, about four to the millimeter and 1mm in
diameter.

This species differs from C. radiatus in its less globular
form, the stouter I[Ax, and the fact that its arms divide above the
Mist nee Oi.

BRACHIOPODA
Genus scHIZAMBON Walcott

Schizambon duplicimuratus sp. nov.
Plate 5, figures 6-7

Description. Pedicle valve subcircular, well rounded anteriorly,
slightly straightened for about 70° on each side of the small and
rather clean cut apex; length of shell 5mm, width 5.4mm; greatest
convexity a little to each side of the pedicle opening and raising sur-
face of shell about Imm above the plane of the shell margin; apex
about .5mm above the cardinal margin and slightly projecting over it.
Foramen subovate, about .88mm wide, anterior edge 1.8mm from
apex, earlier portions filled up leaving a narrow depression with
smooth convex floor, narrowing posteriorly and reaching the extreme
point of the apex. Surface ornamented with nearly concentric,
raised striae which completely encircle the valve; they are single
and rather crowded where they cross the cardinal area but are
strongly raised and distinctly wider and double over the anterior and
lateral regions of the valve. In front of the pedicle opening eight
pairs of these striae can be counted in the length of 2.5mm on
anterior portion of vertical axis. The spaces between one pair and the
next are rather deep and .2mm wide, the distance across each pair
is slightly less. The outermost rampart on the double portion bears
a fringe of short spines set about .12mm apart.

Brachial valve similarly ornamented but less produced posteriorly
along the cardinal margin.

Observations. ‘This species seems to be a little larger than S.
typicalis Walcott, and to differ from that species in its rela-
tively larger pedicle opening, its more nearly spheric or transversely
oval outline, and in the prominent and double, not lamellose, striae
over the anterior and lateral slopes of the shell surface.

Described from three specimens, one of them collected by Mr
Percy Raymond and kindly sent me for comparison.

REPORT OF THE STATE PALEONTOLOGIST I903 285,

Genus syntropuia Hall and Clarke
Syntrophia multicosta sp. nov.
Plate 5, figures 8-15

Description. Shell outline semioval, in some specimens inclining

toward subquadrate; hinge line straight, usually equal to greatest
transverse diameter and in a large specimen measuring 16mm. In
such a specimen the length would measure 10.5mm and the distance
from hinge line to apex of pedicle valve 8mm. Cardinal angles
about 90°, not rounded, sides generally rather straight and parallel
for a distance reaching nearly to the ends of the transverse axis; the
anterior half of the shell uniformly rounded saye for a distinct flatten-
ing of the anterior margin. |

Pedicle valve with wide flat cardinal area the sides forming an
angle of from 95° to 110° at the beak; beak slightly convex; the
slope from beak to valve margin quite straight and nearly uniform
in all directions. Delthyrium triangular, two thirds as wide at the
hinge line as it is high, and reaching apex.

Brachial valve nearly flat with a very shallow sinus, not showing
in all specimens.

Radiating costae are numerous and nearly uniform in size from
near the point of their origin to their termination on the margin;
as shell growth proceeds new costae are added by implantation.
Shells about 2.5mm long have some 33 costae, shells of 5mm length
have about 49, while adult shells have 81 and over. In figure 13,
plate 5, if the two strong costae on either side of the midcosta are
traced to their termination on the margin they will be found to have
II costae between them instead of one. The new costae do not seem
to have been added in regular order, for while the new group of five
to the right have their middle one the longest, the middle one of the
new five on the left is the shortest and youngest. The costae are
crossed by fine raised striae, about .25mm apart. In the gerontic
stage the additions to the shell margin of the brachial valve tend to
add very markedly to its convexity.

The interior of the brachial valve shows a strong and prominent

mediar ridge starting from the middle of the valve and widening

286 NEW YORK STATE MUSEUM

backward till it meets the cruralium. This ridge gives off two |
lateral branches from its middle portion, equally raised but narrower |

and pointing toward the ends of the transverse axis. These ridges |
form the inner boundaries of four deep muscular pits of nearly equal _

size. The posterior pits with a very slight additional extension back- |
ward would leave the cruralium as a narrow platform supported by —
the wider portion of the median ridge. The two anterior pits are a
little nearer together and each shows three distinct muscular impres-
sions separated by two very narrow and slightly raised ridges. The
middle scar of each three is the largest, is subtriangular, and has its
apex pointing a little inside of the well marked dental sockets; the
outer pair are a little smaller, of nearly the same shape and with apex
pointing very nearly toward the small, narrow cardinal process; the
outer impression of the three is a little smaller still and rather
rounded in outline. The pedicle valve bears a wide spondylium well
raised from the valve and supported by a fine and narrow median
septum which is continued anteriorly to the middle of the valve.
The arrangement of the genital and pallial sinuses is shown in plate
5, figures 10, 14. The muscular areas on the spondylium are not dis-
tinctly separated but one can distinguish three tracts, a central and
two outer of nearly the same area, the boundaries of which are not
sharply limited. The delthyrium is bordered by a narrow raised
ridge which is continued around the cruralium of the brachial valve.
At the apex this well rounded border meets a straight raised ridge
tangent to the curve, and just anterior to the ends of this ridge, and
outside of the curved border, are two short, narrow, depressed pits
usually worn off in most of the valves found. .

the beaks are at the angle, and are therefore well forward; the hinge
line carries the middle portion of the dorsal line above the flat plane
of the umbones and gives the shell a very slightly alate appearance ;
posterior margin about twice the length of the anterior and quite
regularly curved, the sharpest bend being found at the posteroven-
tral margin; ventral margin very slightly convex, a little more
straightened in middle portion and forming an angle of about 25°
with the general dorsal area as viewed across the shell; the basal
line forms an angle with the margin of the anterior truncate part
of a little less than g0° and the curve of the basal margin gradually.
and regularly increases till it meets the margin of the anterior trun-
cate portion in a well rounded angle. Extreme breadth of shell 3mm
and at a point but little anterior to the middle and very closely half-
way between dorsal and ventral margins. Beaks incurved and nearly
touching, byssal pit just below them and the cause, in part, of the
truncate appearance. Surface very regularly curved, the usual
oblique ridge from beaks to posterior margin not prominently
marked. Concentric growth lines very fine and numerous but not
easily seen.

(posterior hight of shell); posterior margin convex and quite
closely forming the arc of a circle of Iomm radius with center on
axis of greatest length; the arc extended forward would follow the
shell for about one fourth of dorsal margin and then enter the shell
again at or very close to the beaks; ventral margin but little con-
vex, nearly straight to point directly below beaks, anterior hight
7.7mm; anterior margin at first following the gentle curve of the
ventral margin, but becoming markedly convex when it rounds back
toward the beaks; the outline of the shell with the exception of the
segment cut off by the straight hinge line and the projection of the
anterior margin closely resembles the outline of the gibbous moon.

288 NEW YORK STATE MUSEUM

Crescence line diffuse, well curved, slope of surface of shell from
this line to either margin gently convex; greatest breadth of shell
on this line about one third way from beak to posterior angle and
measures 7mm. The surface is lamellose and imbricated, lamellae

widen as posterior angle is approached and are there placed with
their edges something over 1mm apart; they project from the shell _
about 1mm or a little more and become crowded on the margin dur-_
ing the gerontic stage.

The valves seem to gape very slightly at the anterior extremity,
perhaps indicating a byssal opening. Area crushed in, but posterior
extremity of hinge line presents a well formed channel between the
winglike posterodorsal extension of the valves, as in Unio
alatus, as if to receive a parivincular, opisthodetic ligament.
The shell substance is rather thin near the middle of the valve and
becomes markedly thicker near the posterior margin. |

A line connecting a series of points placed at the successive posi-
tions of posterior extremity of shell (measured from the probable
position of the beaks) marks also the places of greatest breadth met
in crossing the shell and lies over the path of the successive positions
of the posterior adductor. A line from apex to posterior extremity
of one of the earlier neanic stages, when the shell had attained about
one third its length, makes an angle of 30° with the hinge line;
during the growth of the remaining two thirds of the shell this line
is gradually turned away from the hinge line through an angle of —
am additional 27°.

GASTROPODA
Genus EuNEMA Salter

Eunema historicum sp. nov.

Plate 4, figure 5

Description. Shell small! turbinate, apical angle 80°, whorls
about four. ‘The body whorl shows five well marked minutely tuber-
culate spiral costae with trace of a faint sixth at the broken edge, —
well down on the base. The first costa (numbering down from

*The type specimen, being broken diagonally across the lower portion of
the axis, has lost the aperture while the apex and most ot the body whorl
are preserved; it has a hight of 4.3mm.

suture) is sharp; the second and third are more raised, prominent,
blunt, and each about one fourth as wide as the interspace; the
fourth is a little nearer the third, less prominent and narrower; the

fifth is nearer the fourth by about half the distance between fourth

—

and third and is about half as wide as the fourth.

Following the outline of a vertical section through the body
whorl, the shell is seen to be slightly angulated; from suture to
outer edge of first costa the line is straight and at right angles to
the axis; a straight line taken from first to third costa would make
an angle of about 23° with the axis; the projection of the second
costa beyond this line gives a slight convexity to this spiral belt of
the whorl; the outer edges of the third, fourth and fifth costae are
more nearly in line with each other and this line is nearly parallel
with the axis of the shell, its inclination toward the base being but
slight; from the fifth rib the surface approaches the axis by another
flattened belt, at an angle of about 45°; the final approach to the
axis is lost. ‘The intercostal spaces are concave, the amount of
concavity increasing markedly as the lower costa is approached,
giving a rather horizontal surface to the upper portions of the
stronger costae or in certain lights making this upper edge appear
slightly reflexed. The suture lies at the base of the nearly vertical,
spiral belt or just under the fourth costa and is thus situated at the
apex of a clearly cut right angle, two sides of which are formed
by the flattened belts already described. The shell is faintly marked
with transverse striae the more prominent of which are about 2mm
apart; between these a still fainter line can in many places be dis-
tinguished; their direction is at first very nearly perpendicular to
the suture and on the body whorl they appear to run gently back-
ward from the fourth costa; they are more easily seen above the
suture and here seem to be nearly vertical across and beyond the
fourth costa; finer growth lines may be detected.

A little more than the first whorl of this specimen is somewhat
Natica-like, not angulated, destitute of costae, and the apical angle
is more obtuse being about 90°. The transverse striae seem to
appear first and are present on the second whorl. The vertical and
horizontal flattened belts are present on the third whorl and the first,

|

290 NEW YORK STATE MUSEUM |

second, and third costae aré clearly developed; the fourth costa
seems to have had a later origin as it is not detected till we reach |
the later portions of this whorl. The intercostal spaces on the third 7
whorl are more uniform and not so deeply concave; the gradual

change to the greater concavity near the lower costa can be easily

seen in different portions of the fourth or body whorl.
The name historicum was suggested by the well presented
ontogenic series in shell growth. 3

Eunema epitome sp. nov.

Plate 4, figures 6, 7

-

Description. Shell small, turbinate, apical angle about 80°, length
10.3mm, whorls about four and one half, upper surfaces a little
flattened giving a distinct conical aspect to the upper portion of
shell. A well marked keel on periphery and three more of like
character between this and the suture; these four keels nearly
equidistant and clearly defining the broad, shallow, concave grooves
which lie between them. Keel next the suture and distant from
it about half the width of one of the grooves, finer and sharper
than the others, the second keel from suture strong and rounded
and touching the sides of the apical angle. The suture is formed
on the peripheral or fourth keel, and the half groove of the body
whorl is made to fit the base of the smaller groove of the whorl
above in such a manner as to make the suture show as a simple line
in the middle of a groove very similar to and but slightly deeper
than the others. Base of shell near termination of penultimate whorl
nearly flat making an angle of about 90° with upper surface; nearer
the aperture the base becomes more convex and a tendency to lose
gradually the angle of the penultimate whorl is well marked; the
last third of the body whorl is lost but the changes introduced point
to a well rounded aperture. There are five revolving keels on base,
the three next the columella being the finer and closer together ; two
new ones with trace of a third are introduced soon after the com-
mencement of the last whorl and are in position still below the three
last mentioned. Very fine and obscure transverse striae, about seven

as

REPORT OF THE STATE PALEONTOLOGIST I903 291

to the millimeter, run backward from the suture and each keeps
approximately in the plane of its origin till it terminates on the
columella.

Observations. The apical angle of the shell in its two whorl stage
is considerably over 100°, and becomes reduced to about 80° on the
completion of the third whorl; on certain lines the fourth whorl
rather increases this angle and so makes the outline across three
whorls from shoulder to shoulder slightly concave. The revolving
keels appear in the second whorl.

The earlier portions of the suture are a little more angulated, but
acceleration seems to have carried back toward the apex the peculiar
feature of making the suture appear as one of the grooves.

The slight flattening of the upper surfaces of the whorls and the
very marked obliteration of the suture by turning it into a groove
so very like the others may have served to make the shell less readily
distinguishable, as such, to the primitive perceptive powers of some
important enemies.

The introduction of the new keels and the widening to which they
must have been subjected during the probable inflation of the base
of the whorl and the rounding of the aperture suggests that the
grooving of the upper portion of the whorl was later carried to the
base of the last half of the body whorl. This change was probably
induced by a changing in the position of the heavier shell during
locomotion or rest, and enabled the possessor to still present the
peculiar grooved aspect whatever may have been its purpose.

This shell also seems to recapitulate in its ontogeny some interest-
ing features of its very remote history and at the same time, when
compared with modern shells, to show quite as remarkable an ac-
celeration as many of these; the name epitome therefore is suggested

as an appropriate one.

Eunema altisuleatum sp. nov.

Plate s, figure 3

Description. Shell small, turbinate, pyramidal, apical angle 52°,

hight 6mm. Whorls four, uniformly increasing in size, hight and
width of body whorl to total hight closely in ratio of 3:5; three

prominent, projecting and clear-cut revolving keels on penultimate
whorl, the uppermost of which is the weaker and forms the outer
edge of a flat revolving shelf which is depressed at an angle of
about 115° from the vertical axis. The edge of this keel is narrow
and rather vertical. Just under it a second shelf commences, having
about the same width and angle as the first; it is slightly concave
and is limited by the second and stronger keel. Under this is a
wider, more strongly concave space with its lower border sloping
down at an angle of about 45° to the vertical; the limiting keel to
this revolving groove is the strongest and most extended of all.
The edge of the shell is now cut strongly back, beginning at an
angle of about go° with last surface and curving down to a very
fine keel immediately above the suture or reaching the suture itself.
The suture thus comes to lie in the widest and deepest revolving
channel of the shell. There are five or six fainter revolving keels
on the base but the shell is not depressed between them; the three
next to the columella are the nearest together. The lip is broken
but appears to have been well rounded and to have been slightly
extended over the columella at the base of the outer lip so as to
leave a very narrow and slitlike cavity appearing like a nearly cov-
ered umbilicus. The revolving keels do not begin to show till the
latter part of the second whorl. Very fine and faint transverse

striae, about 10 to the millimeter, cross the later whorls, and the

edges of the keels are slightly roughened or finely nodular,

Genus suBULITES Conrad
Subulites raymondi sp. nov.
Plate 4, figures 1, 2

Description. Shell small, fusiform; apical angle about 44°;
length of specimen, with apical whorl, or a little more, lost, 9.5mm;
greatest thickness across axis at middle of shell 3.4mm. Whorls
five or six; penultimate whorl showing a rapid elongation, body
whorl 6mm long or considerably longer than the spire.

Aperture elongate, oblique, narrow, with well formed anterior
canal; inner wall of aperture nearly straight; outer lip convex,
gradually increasing its distance from the axis for about one fourth

its length, remaining very nearly parallel for another fourth and
: then slightly increasing its convexity to anterior extremity. With
aperture toward the observer, the shell appears slightly angulated
at a little above middle on the left, and a short distance below the
| middle on the right; turned toward the left through 90°, the right
hand outline is more uniformly convex. Suture but slightly im-
pressed ; surface smooth.

Observations. ‘The shell surtace is well preserved and in some
| lights seems to show growth lines much like those of Terebel-
lum subulatum Lam.,, to which this species shows a super-
' ficial resemblance in its spire, inner wall of aperture, and anterior
canal. With other lighting however there seem to be growth lines
“running gently backward from the suture. These lines are not
| easily seen and some of them may be due to marks made in cleaning

| the specimen. Still very faint but more easily seen are some ex-

; tremely narrow, fine, raised, transverse striae about 4mm apart.
This species has been named after Mr Percy E. Raymond, of the
| Carnegie Museum, Pittsburg Pa. who found the species in material
from the section described.

Genus nonopea Hall
Holopea microclathrata sp. nov.
Plate 4, figures 3, 4

Description. Shell small, turbinate, apical angle about 73°, length
of type specimen in which apex and last fourth of body whorl are
lost, measured from broken part of apex to most distant point on
body whorl 8mm. Whorls about four, becoming gradually more
oblique, longest diameter of body whorl near the aperture making
an angle of about 50° with the vertical axis. Base of penultimate
whorl slightly flattened and making an angle of about 90° with
upper surface; angle well rounded and upper surface moderately
convex; outline of whorl rapidly becoming more rounded as aper-
ture is approached. Columella apparently strong and thickened and
there seems to be a small umbilicus; no trace of lip across wall of

aperture. Eight fine revolving, raised striae between suture and

periphery ; on the penultimate whorl the first, second, fourth, sixth —

and eighth are the more prominent of these. The spaces before the

first and between this and the second are a little wider than the |

|
|

others and are gently concave; the third stria (the first of the |

fainter or secondary striae) lies at the center of a wider and shallow

concave belt limited by the second and fourth striae; after the
second the distance between striae is quite uniform and the secondary |
striae are nearly as prominent as the primary and are but slightly ©
or not at all depressed below them. There is a peripheral stria and |
eight or more similar striae on base of penultimate and body whorls.
The shallow spaces between the striae are crossed by very fine and

sharp, raised, transverse striae, as close as 17 or more to the milli- |

meter. These striae pass slightly backward from the suture, curve |

regularly and gently across the whorl and become directed forward

on the base. Viewed from the middle of the whorl the lines appear |
to make no deviation whatever in any part of their course from the |

vertical plane of their origin. The suture forms a fine, rather im-

pressed line just below the eighth stria, the whorls meeting at an !

angle of about 90°.

Description. Glabella somewhat resembles a medieval, conical
helmet, rising from the frontal rim with a curve of about 6mm
radius for one third the distance to the apex of the cone. In the
other two thirds the convexity becomes markedly less and the apex
‘is approached with but very slightly convex outlines; from the apex
‘to neck furrow the outline is at first concave and then straight.
The cone or spur is thus rather high and produced backward over —
‘the neck ring. Length from frontal furrow to neck furrow 13mm,
from frontal furrow to apex of cone 15mm, hight of apex of cone
above neck furrow about 8mm, width of glabella just in front of
‘tthe neck ring nearly 12mm. The glabellar furrows are convex
toward the front throughout their length; the two anterior pairs
reach to a little less than one fourth the distance across the glabella ;
the middle one is most convex toward the front; the posterior fur-
‘row is less bent at first, reaches about halfway to the apex of the
‘cone and is bent so as to meet its axis at an angle of about 70°.
Marginal furrow of glabella rounded in front, distinctly angled as
it turns to pass along the sides, where it is concave toward the under
surface with a radius of about Iomm.

Differs from C. vulcanus Billings, in the pronounced char-
‘acter of the conical spur, the absence of a sigmoid flexure in the
‘posterior pair of glabellar furrows, the shortness of the two anterior
pairs, and the front angles of the margin. Described from a cast
ithe surface of which is smooth.

THE STRUCTURE OF SOME PRIMITIVE CEPHALOPODS

BY R. RUEDEMANN
Plates 6-13

Professor Whitfield has described [1886,! p. 319], as Orth om
ceras brainerdi, a cephalopod from the Fort Cassin
(Upper Beekmantown) beds of Fort Cassin Vt., which is also:
very common in beds of like age outcropping along the shore of
Lake Champlain at Valcour N. Y. While the originals of the
species exhibit but fragments of the phragmocone and lack the
living chamber and the apical parts of the conch, there are in
the extensive museum collection of specimens secured at Val-
cour, not only conchs which supplement the original material
but also a great number of siphuncles which exhibit interesting
internal structures.2. These and the peculiarities of the apical
portion of the conch have led to the investigation, whose results.
are herewith presented. An extension of the research to the
siphuncles of Piloceras explanator Whitfield, another
form which is equally common in the Fort Cassin beds at the
type locality and at Valcour, has brought to light homologous.
structures which are also described here. |

1 Parts of siphuncle

In a siphuncle of the mature conch of Cameroceras®
brainerdi four well defined parts, succeeding each other
in apertural direction, can be differentiated. For reasons of
plainer demonstration we will consider them here in the reversed
order of origin or in apical direction. The first portion of the
siphuncle of this species is entirely empty, as in Orthoceras [see

; /
1See list of references.

2Subsequently these structures were also found in specimens from
Fort Cassin itself, which are a part of the State Museum collection.

3We use here the older term Cameroceras not differentiating between
Cameroceras and Endoceras, as Hyatt has done.

pl.6, fig.2]. The septal necks,! however, do not as in most ortho-
ceratites extend only a short distance backward, but curve first gently
inward, thus contracting the siphuncle slightly and just above the
preceding septum bend again outward, growing thicker and standing
on the latter septum. The cameras are thus completely shut off
from the siphuncular space. There is, however, no separate siphun-
cular wall present in this part, the septal necks forming the only par-
titions. The proportional length of this part to the total length of
the conch I have not ascertained; it is, however, certain that this
open siphuncle extended for the distance of several inches apicad
from the living chamber.

Under the second part of the siphuncle we comprise that por-
tion in which the organic deposits characteristic of Cameroceras -
and consisting of endocones begin to form. The space included
by the last formed endocone is a cone with elliptic or more

frequently subtriangular section, the base lying parallel to the
flat side of the siphuncle [see pl.8, fig.7]. The more convex
side is provided with low annulations which are slightly convex
forward. The cone is always filled with matrix, like the living
chamber and open part of the siphuncle and is what Dewitz and
other authors have termed the “ Spiess” (or dart) of the endocera-
tites. The last endocone is in sections [see pl.o, fig.2] distinctly
set off by its darker color from the coarsely crystalline white calcite
infilling of the more apical portions of the siphuncle, which suggests
that, when left behind by the advancing animal, it contained con-
siderably more organic matter than is found in the solid part of the
siphuncle where calcite infiltration has taken place. This endocone
connects with a cylindric layer of equally carbonaceous lime car-
bonate, which being directly adjacent to the septal necks, lines the
entire siphuncle and extends forward into the first part to an extent
at present not known to me, but certainly not comprising the
entire first part, for its absence in the siphuncle for several inches
from the base of the living chamber could be ascertained in

1We prefer the older term “septal neck” to the later “funnel” pro-
posed by Hyatt for the reason pointed out by Foord [1888, p. 130] that

several specimens. In the opposite or apical direction it extends close
to the tip of the siphuncle. This internal lining layer of the siphuncle
will be termed in this paper “ endosipholining ” | see p.303].

The third part of the siphuncle is that which has been filled
by the endocones, but is still surrounded by the cameras of the
phragmocone. The endocones have mostly become obliterated
by the formation of coarse white calcite, but from the endosi-
phuncular canal there still proceed at intervals short lines which
are parallel to the last endocone and represent the bases of
former endocones [see pl.g, fig.2]. Occasionally also the entire
walls appear still as gray lines in the calcite filling [see pl.6, fig.3].
The “dart” or “ Spiess’ extends at its apical end into a flat broad
tube, which frequently passes through nearly the whole width of the
siphuncle and which possesses strong, deep black walls of velvety
appearance, suggesting their composition of conchiolin. This flat
tube is the first part of the endosiphuncle.t The latter passes through
the whole length of the siphuncle. Its characters are such as to
invite detailed description, which will be given below.

The fourth part of the siphuncle of this species is that which
projects apicad beyond the camerated portion of the shell (the
phragmocone), and which, hence, was entirely free. This part
is identical with the apical cone of Nanno aulema Clarke
and Vaginoceras belemnitifor me Wlolmemeieees
however, not short and strongly inflated, but long and gradually
widening at approximately the same rate as the anterior parts
of the siphuncle. This free portion may have easily reached
a length of 70 mm as the finely preserved specimen reproduced
in plate 6, figure 3 indicates.

It might be presumed that in the specimens in hand the septa
continued further apicad than their present preservation would

——

indicate, and that the free apical cone is more due to incomplete —

1We use here provisionally, till further definitions have been given, Hyatt’s
term “endosiphuncle” for the central tube of the siphuncle. Hyatt’s defini-
tion is [1900, p.515]: “ Organic deposits in the form of endocones, and taper
off at the center into a spire that is sometimes tubular and hollow, or again
flattened and elliptical. This is the endosiphuncle.” Before this definition
the term “endosiphon” had been in use for the same organ.

REPORT OF THE STATE PALEONTOLOGIST 1903. 299

retention of the phragmocone than to its original absence in the
apical portion of the shell. Since however in this species the septa
by their septal necks or funnels form a continuous ectosiphuncular
wall, which is thicker than the septal partitions and is readily dis-

tinguishable in one specimen [see pl.6, fig.3] by its light gray

color contrasting with the black matrix, we have carefully searched
for traces of this wall along the apical cone, without finding any
beyond the contraction of the shell at the beginning of the visible
chambering of the conch. A black conchiolinous deposit forms the

~ undoubtedly outermost wall of this preseptal conch.

A little forward of the beginning of the cameras (about the
fourth camera) there occurs a distinct contraction, as in the
corresponding places in the species cited above. The apical por-
tion of this free part is slightly curved. The endosipholining,
which in the phragmocone is adjacent to the septal necks, extends
through the full length of this apical free part of the siphuncle
[see pl.3, fig.3]. It contrasts distinctly with the white coarse calcite
filling of the siphuncle and retains its full width and sharp delimita-
tion to within 30 mm of the apex, when it begins to thin out; and
about 15 mm from the apex it has disappeared entirely, the siphuncle
being there wholly filled by the white sugary calcite. The extension
and composition of this layer of carbonaceous calcite leaves no doubt
that it originally formed within a membrane and thus became
charged with organic matter. This endosipholining is in section
sharply outlined by a fine black line which represents an outer
conchiolinous shell layer. This also extends into the chambered
portion of the shell, at least into its earlier part. It is this layer
which gives to the separate siphuncles of this species their black,
shiny surface. There is no doubt that this is identical with the
cuticle of horny matter which incases the whole mantle and also the
siphuncle of Nautilus, and which also has occasionally been observed
enveloping the siphuncle of fossil cephalopods.

The endosiphuncle passes unrestricted to the very apex of the
siphuncle, where it distinctly empties to the exterior [see pl.6, fig.3].
Its last apical part (about 1 mm) is filled with black material which
appears to be the same as the matrix. This suggests that in this

300 NEW YORK STATE MUSEUM

form, asin Nanno aulema (according to Hyatt’s observations)
the endosiphuncle communicated for a time with the exterior, viz
from the time of the destruction of the protoconch to that of the
plugging of the canal between the first and second endocones. At
the time of the burial of the shell in mud, this short end of the canal
was still open and the surrounding
mud could enter it. In the remaining
portion of the endosiphuncle there
has nowhere beem found any matrix,
in our material, not even directly
behind the Spiess, which is always
filled to near its tip with mud. Holm
comments on this fact, but states that
longitudinal sections through the endo-
siphuncle nowhere suggested the pres-
ence of any transverse partitions and
assumes that soft parts of the decaying
animal, remaining in the “ Spiess ”
prevented the mud from entering the
endosiphuncle, which apparently was

Nanno aulema however, as men-
tioned above, Hyatt observed a closing of the tube in front of the
first endocone. Partition lines, forming acute angles with the endo-
siphon, leave no doubt that also the apical cone of Cameroceras
brainerdi was provided with endocones though no traces of

the same have been observed close to the apex.

1Whiteaves [Roy. Soc. Can. Proc. & Trans. 1891, 9:79] has recorded
that in one specimen of Endoceras (E. crassisiphonatum)
from the Trenton limestone of Manitoba, “the interior of the narrow
posterior end of the siphuncle (endosiphuncle) appears to be portioned |
off by a few transverse concave dissepiments” [see text fig. 1]. Since
there exists an early genus (Diphragmoceras Hyatt) in which the
siphuncle is divided by tabulae alternating with the septa of the
camerated shell, it is quite as possible that the endosiphuncle also may
have been tabulated in some forms, though Whiteaves’s observation
seems to stand quite alone at the present time. The observations of
both Hyatt and Whiteaves would seem to support Zittel’s view that
the siphuncle has no particular function but is only a residual.

2 Former observations on endosiphonal structures and the termin-
ology of the latter

The endosiphuncular structures of Cameroceras brain-
erdi which concern us most here are the flattened tube extend-
ing backward from the “Spiess,” the fine, often capillary tube
extending the greater length of the siphuncle and certain thin
longitudinal layers of dark organic limestone radiating from these
tubes to the walls of the siphuncle.

The attention of paleontologists was directed to similar
structures only a comparatively short time ago, though the fine

threadlike endosiphuncle had already been noticed by Barrande

in a Newfoundland species (Orthoceras insulare)
Prev ico7, vil 1.430, fig.5, 8-11; t.431,
fig.8-10] and also been described by Dewitz
[1879, p.172, 173, fide Holm] and Schroder
[1881, p.76, t.2, fig. 8d]. Dewitz also men-
tions [1880, p.377] that “in some species
membranes seem to have proceeded from
the posterior end of the fleshy siphuncle,
which often, at least for some distance, agen ecucncreimmanae:
s, siphuncular side; as, anti-
extended to the internal wall of the eae side. (Copy from
siphuncular tube, and which also secreted
covering sheaths, in which organic carbonate of lime was deposited,”
and adds, “ These membranes probably served to attach the posterior
end of the fleshy siphuncle to the interior wall of the siphuncular
tube.” He also figures a transverse section of Endoceras

commune [pl.17, fig.7] which shows three longitudinal mem-
branes radiating from the endosiphuncle, but which do not reach
the siphuncular wall [see text fig.2].

The’ flattened tube extending from the “ Spiess” appears to
have been first noticed by Dawson in a species of Piloceras
[1883, p.4]. Sir William states [p.3] that “the lower part of
the shell is divided by a vertical partition crossing its longer
diameter,” and again [p.4] that the internal cone “is flatter
than the siphuncle, ending at the apex in an edge which is
attached to a central shelly plate crossing the lower part of the

302 NEW YORK STATE MUSEUM

b]

siphuncle,” and adds, “ This plate shows at intervals slight pro-
jections giving rise to delicate cones apparently membranous.”
Hyatt [1884, p.266], though basing his definition of Piloceras
on Dawson’s description, did not recognize the presence of a parti-
tion, but believing in its tubular character, referred it to the endosi-
phuncle. Foord, however, observed again the same plate in a
Piloceras from Durness and figured it [1888, p.159, fig.17, III,
p.160], stating in regard to it in opposition to Hyatt’s view:
“ Nevertheless there seems to have been an internal septum

extending upwards, from the lower part of the siphuncle, between —

the wall of the latter and that of the sheath into which the
endosiphon opens. ‘This septum shows itself in some transverse
sections of the sipnuncle in the manner indicated at figure 17, II
[copied here in text fig.3], and it can be
traced for some distance upwards in the
vertical section of this and of other speci-
mens. The septum seems to have been
penetrated by the endosiphon, as shown in
Transverse seetionof nae nee i figure, but I am una to ene ae
(Copy from Foor) PD °™ ~—s satisfactory account of it, owing to its im-

perfect condition.” Bather later [1894,
p-433] copied Foord’s figure, stating that the appearance of the par-
tition is exaggerated and its significance unknown. Specimens of
Piloceras explanator from the Fort Cassin bed, which
are in the State Museum, show the same partition and we shall have

occasion to recur to its structure [see p.329].

Meanwhile Holm had found a similar endosiphuncular blade
strongly developed in a species from Esthonia, which he described
in allusion to this feature as Endoceras gladius [1887,
p.13]. In this important publication, to which we shall have frequent
occasion to refer, Dewitz’s observation of the winglike membranes
of the endosiphuncle, is verified.

In a later publication [18 95, p.605ff] the same author has
introduced a number of terms for the parts of the siphuncle in
view of the fact that Bather had criticized Hyatt’s term *

siphon” [J/. c., p.433] arguing that the ‘“endosiphon” is in func-

“ endo-™

REPORT OF THE STATE PALEONTOLOGIST 1903 303

tion the real siphuncle. As Foord [1888, p.132] has pointed
out “exception might perhaps be taken to this term on the
ground that it seems to imply the existence of two siphuncles,
an inner and an outer one.” Since, however, it will be found
convenient to distinguish the fleshy siphuncle from the shelly
wall that separates it from the septal chamber, and the term
siphuncle has always been used in the latter sense in relation
to fossils, he considers the employment of the additional term
justifiable. To avoid its illogical and confusing use Holm has
proposed a series of terms which it seems practicable to adopt

‘

here. These are “ectosipho” for the outer siphuncular tube—
“sipho ” being retained for the entire organ—‘ endosipho” for
the contents of the ectosipho as a whole;! also for the parts of
the endosipho are proposed new expressions. He terms
“ endosiphocylinder ” the wider portion of the siphuncle, which
is entirely occupied by the more cylindric anterior part of the
fleshy siphuncle. This passes posteriorly into the “ endosipho-
cone” (its walls are Hyatt’s “endocones”); from this again
proceeds the narrow canal which was termed first “ endosiphon ” and
later “ endosiphuncle ” by Hyatt and for which is proposed the word
“endosiphotube’”’ by Holm [see text fig.18]. We have, in accord-
' ance with this terminology, proposed above the term “ endosipholin-
ing’ for the inner, thick, continuous layer of the siphuncular wall,
which, according to Hyatt [1884, p.266], is characteristic of Camero-
ceras (Sannionites) in distinction from Vaginoceras and Endoceras.
This layer is shown in plate 6, figure 3 and text figure 15 (e sc).
and the sections on plate 7. To the endosiphuncular formation belong
further thin, calcified membranes which connect the endosiphotubes
and endosiphocones with the ectosiphuncle, and a broad conchio-
linous double blade, extending backward from the endosiphocone.

The latter structure was originally termed by Holm, who was

1Following Hyatt in making a strict distinction between the fleshy
“siphon” and its calcareous covers, the “siphuncle,” we will employ
here the terms “estosiphuncle” and “endosiphuncle.” This usage will
not vitiate the terms “ endosiphocylinder” etc. in which only the radicle
of the word siphon is incorporated; nor will it cause confusion since for the
organ termed “endosiphuncle” by Hyatt, a new term is proposed.

304. NEW YORK STATE MUSEUM

the first to clearly recognize it, “ schwertahnliches Blatt” [1887].
Later [1895] the same author introduced the term “ endosipho-
blade” (“ endosiphobladet ” in the Swedish original) and defined
it as the thin calcified endosiphuncular membrane which extends

¢

longitudinally in several species of Endoceras and Piloceras and
connects the endosiphotube and endosiphocone with the inside
of the ectosiphuncle. It becomes evident from the discussion of
this organ in the last cited publication that this term is meant
to comprise both the hollow blade and the calcified suspensory
membranes. |

~ Since we shall show in this paper that the endosiphotube is a
new formation, at least in our species, within the broad hollow
endosiphuncular part, first called “schwertahnliches Blatt” by
Holm, and also that the latter and the suspending membranes
are of different origin in our form, it becomes desirable to dis-
tinguish between these two organs which are comprised in
Holm’s term “ endosiphoblade.” We will therefore, in view of
Holm’s definition, retain this latter term for the suspensory mem-
branes and designate the broad and originally hollow endosi-
phuncular “ Blatt” by a new term.

Holm named the species, in which he observed it, Endo-
ceras gladius in allusion to this swordlike blade. “Gla-
dius” would therefore be an appropriate term, were it not for the
fact that this word is already used for the cuttlebone or pen of
the cuttlefish. For this reason we shall use here instead the

b)

word “ coleon,’ and to make it conform with the other terms,
call this flattened tube the “ endosiphocoleon.” As “ endosipho-
sheaths” we designate the walls of the funnel-shaped endosipho-
cones (Hyatt’s “endocones”), which are left behind by the

advancing animal.

& Endosiphocoleon and endosiphotube

As we have noted above, Holm was the first to observe, in a
species obtained in Esthonia from a transitional bed between the
Vaginatenkalk and Echinosphaeritenkalk, the organ which we have
found still more peculiarly developed in an American species

REPORT OF THE STATE PALEONTOLOGIST I903 305

and designated as endosiphocoleon. Holm termed the species at
mietime, Rndoceras gla dius, but he later [ 1896, p.400]
Seanited it with Endoceras (Nanno) belemniti-
forme. This again has been referred to Vaginoceras by Hyatt
[1895, p.g]. We will state on this occasion that while we had
worked out the characters of the endosiphuncular organs before
we were aware of Holm’s prior elaborate description, we found
by subsequent comparison that our material on the whole veri-
fies Holm’s observations for the species in hand, but that at the
same time it indicates an origin of the endosiphotube and a rela-
tion between endosiphotube and endosiphocoleon which is dif-
ferent from those observed by Holm. These
and such other differences as have become ap-
parent between the endosiphuncular structures
mee Vacinoceras belemnitiforme
and Cameroceras brainerdi will be
noted at the end of the description of these
structures in our species. We have copied
here for comparison Holm’s figure of the
endosiphocoleon [text fig.4].

The endosiphocone which, at its forward
end, is subcircular and only slightly flattened
on the ventral (outer) side, becomes rapidly

flattened toward its posterior end, the convex p.)._ Longitudinal section

of siphuncle, showing endo-
wall approaching the opposite flat one. It Pewee ee
thus’ runs out into a double blade, which,

lying approximately in the middle of the siphuncle and parallel
to its flatter side, is at first almost as wide as the siphuncle
and nearly touches its walls [see pl.7, fig.1]. This is at least the
case in the large siphuncle of the later portions of the shell when
the animal approaches maturity. This organ is the endosiphocoleon,
which in our material consists just behind the endosiphocone of two
thin, intensely black conchiolinous walls, forming a flattened broad
tube. These walls are composed of extremely thin, concentric or
rather long conical lamellae. They show a double sculpture, viz, low

transverse ribs arching slightly forward and longitudinal lines

306 NEW YORK STATE MUSEUM

which slightly disperse in a forward direction. The low ribs are
evidently the remains of the ribs of the convex side of the endosi-
phocone, noted below.

Holm describes the middle portion of the endosiphocoleon
which proceeds from the apex of the endosiphocone as possess-
ing a very distinct and beautiful sculpture, consisting of growth |

lines. “These growth lines form an arch, which is strongly |
bent backward. Their form and curvature corresponds exactly
with the outline of the apex of the ‘Spiess’ and thereby with:
the outline of the fleshy end of the siphon. On the anterior
portion of the blade there also occur longitudinal lines which

intersect the growth lines.” Our material fails to show these |
growth lines so distinctly, but from the fracture lines of the |
oblique lamellae composing the wall of the endosiphocoleon we
infer that they may be the intersections of these lamellae with
its surface. ;

This middle part of the endosiphocoleon is on both narrow
edges [see pl.7, fig.1; pl.o, fig.1; text fig.14] flanked by strong deep
black conchiolinous semicylindric rods or wings, [w of figures]
which, on the upper and lower side of the blade, quite abruptly
change into a layer of dark gray limestone, such as composes the
endosiphocone or last endocone. They correspond to the winglike
lamellae, which according to Holm begin on the endosiphocone and.
continue along the endosiphocoleon and which we shall discuss later.

The further development of the endosiphocoleon can be best
described by the use of a series of sections which were made
apicad of the part of the endosiphocoleon reproduced on plate 7.
These sections are figured on the same plate and diagrammatic
sketches illustrating the further stages of development are inserted.
in the text [fig.5-12].

Figure 5 of plate 7 [also text fig.10] shows the small, thick |
walled endosiphotube [e s ¢] contained wath the endosipho-
coleon [e s v], which is entirely filled with very dark organic |
carbonate of lime. This observation suggests that the endosi- |
photube is not a narrower apicad continuation of the endosipho- |
coleon, but a new formation within the same; an inference which |
is borne out by the observation of such sec- |
tions as that reproduced in figure 2, ia

through the block containing this turn has been made and the rock
polished down sufficiently to expose the turn [fig.4]. Figure 5
shows the front of the next block, which is identical with the posterior

tow cylindric tube (endosiphotube) sharply limited by a black con-
chiolinous wall. It lies somewhat laterally to a broad, dark gray
brown belt of organic lime carbonate, through which the walls of the

in the next section, figure 7 (7.5 mm distant from 6). In this the
endosiphotube has again decreased since the last section to about |
one half of its former diameter, while the endosiphocoleon has |
retained its width. In the next it has even again become broader. |
Its ends are notably rounder and thicker than the middle of they

composition of the blade of two conjoined lamellae. The entire:
endosiphocoleon, which before had swung to one side, has re- |
turned again to the median line of the siphuncle. |

In this condition the endosiphocoleon remains to the apical end i
of this (not complete) siphuncle, i. e. it extends across the siphuncle |
as a dark gray brown band with indistinct outline which includes |
the fine endosiphotube; its swollen lateral extremities touching or |

coalescing with the gray wall of the siphuncle. Figure 1o is taken
15 mm from the preceding section and shows no material change’

from the latter. It shows white cross-lines which transect the brown |
band of the endosiphocoleon. These are due to secondary, crystal-
lization, the endosiphocoleon being—in contrast to the irregular
crystallization of the remainder of the interior of the siphuncle—
composed of two layers of parallel crystals which distinctly grew

from the median line of the endosiphocoleon as a base. |

Text figure 11 shows the position and extension of the endosipho- |
coleon in a very early portion of the siphuncle or near the apex ‘
[see fig. 7]. It is here a light brown transverse band with a
central black conchiolinous endosiphotube. This condition is |
reached shortly behind the endosiphocone in the earlier portions
of the siphuncle, when its diameter is still small as is exemplified |
by the section [pl.8, fig.1]. |

In order to obtain a complete portrayal of the endosiphocoleon |
and endosiphocone of Camerocetas bravmemcdnmaas |
will add the description of a few other sections which show |
features slightly different from or explanatory of those observed |

in the series of sections noted above. There is, first, the longi- |
tudinal section [pl.9, fig.2] in which a well preserved endosiphocone
with sheath is exhibited which at its apex contains a newly |

formed portion of the endosiphocoleon as a free standing black
and conchiolinous tube! [see text fig.15]. This shows that here the
endosiphocoleon is not a mere continuation of the apex of the endo-
siphocone, as it was found in Vaginoceras be lemniti-
forme but a new formation, growing within the apical part of the
visceral cone, presumably preparatory to a succeeding withdrawal
of the animal from that part of the aay

siphuncle and the formation of a -@SS

new endosiphosheath.

Two sections which exhibit the :

in plate 7, figure 1 and plate 9, :

‘narrow sides of the endosiphocoleon
a series of two black concentric ear

also connected at its convex side to the nearest wall by a band of
crystals of organic carbonate of lime. The interspaces are not only |
arranged symmetrically, but also delimited so sharply by uninter- |
rupted lines, that it is hardly to be doubted that the calcite bands. |
connecting the endosiphocone and wall of siphuncle are the remains
of the membranes which held the visceral cone in position within the |
siphuncle and probably became partially calcified during the lifetime |

of the animal. The interspaces remained cavities till they were

filled by the large calcite crystals now occupying the siphuncle? —

The supposition of the fixation of the visceral cone and inclos-
ing endosiphosheath to the ectosiphuncle, finds support in the |
occasional presence of bands of gray brown limestone, extending
from the endosiphocoleon (virtually the continuation of the vis- |

ceral cone) or more posteriorly from the endosiphotube, to the wall

of the siphuncle. Such a section is reproduced in plate 8, figure 5.
The horizontal transverse band with the inclosed endosiphotube is-
evidently the “ endosiphoblade” of Holm. This is held in a manner
corresponding to the fixation of the endosiphocone described above
by a band that is placed perpendicular to the endosiphocoleon2 The:

*In this particular siphuncle the interior is 20 mm from the end of the |
endosiphocone already so calcified, apparently by secondary calcification, |

that hardly any trace of the endosiphocoleon is left [see pl.8, fig.8].

*These supporting membranes were, as we have mentioned above, |
recognized by Dewitz and more fully described by Holm. The latter |
author [I c., 1887, p.16] sums up his observations on these supporting |
membranes in Endoceras gladius in the following statement: |
“During the retrogression of the siphon in the siphuncular tube there were |
secreted by the siphon three longitudinal membranes which were prob- |
ably soft, pliable and extended to the wall of the siphuncular tube, one |
from each of the angular marginal edges and one from the median line of |
the convex side. Their function was probably to fix the end of the |
siphon, which was suspended in the siphuncular tube in a position in the

middle of the latter. A similar organ was, as we have seen above, ob-
served by Dewitz in the siphuncular tube of a specimen of “Endo-

ceras commune.” In consequence of this structure the “Spiess” |
maintains in all specimens of the species in question, which have been _
investigated by me, the same position in the middle of the siphuncular |
tube and indicates an invariable position of the end of the siphon. The |
thin (cuticular) membranes were secreted along the whole length of the |

siphon.”

_ the supporting membranes indicate that the latter already supported
the visceral cone before the formation of the last endosipho-
sheath, determined the form of the latter and at the time of its forma-
| tion probably became the situs of organic deposits of lime carbonate.
_ This latter view is at least suggested by the presence of cavities
_ between the well defined bands of lime in the section.

If these membranes served as suspensory organs of the visceral
cone and its posterior extension, their arrangement will give us a

hint as to which side of this Cameroceras conch was the ventral side
or turned habitually downward in the moving animal, the position
of the siphuncle on one side of the conch not being a reliable criterion

i

on account of its shifting sometimes in the same individual. It
will now be noticed that in the sections reproduced in plate 8,
figures 5, 6, the tube is suspended by three membranes, two of which
form a diameter of the siphuncle, parallel to its flat side, while

the third holds a perpendicular position to this diameter and
connects the tube with the side of the siphuncle diametrically
opposite to its flat side. If now a tube is suspended by means
of three membranes, forming an inverted T, it is evident that
the middle was the upper one. The alternative possibility that
the tube was held by props or propping blades instead of by
membranes, in which case the relation of the three blades would
be inverted, may be neglected on account of the evident thinness
and frailty of the supporting organs. It then follows that the
flat side of the siphuncle which is in contact with the conch was
the lower or ventral side.

4 Comparison of endosiphuncular structures in Vaginoceras belem-
nitiforme and Cameroceras brainerdi

Holm’s elaborate description of the endosiphocoleon of
Vaginoceras (gladius) belemnitiforme permits
a close comparison of the development of this organ in the
Swedish type and in this American form.

In the description of the endosiphocoleon of V. be lemniti-
forme a distinction [I. c., p.14] is made between the lateral and

314 NEW YORK STATE MUSEUM

middle parts of the “ Blatt.” The former are described as being
a continuation of the two winglike lamellae that flank the en-
-dosiphosheath and the latter, which is characterized by its sculp-
ture, aS a continuation of the middle part of this endosiphosheath.
‘This difference is in our material, if anything, still more apparent,

and the two parts are entirely separated owing to their different —
places of origin. The wings are formed on the outside of the

endosiphocone, while the middle part, which is the real tube of
the endosiphocoleon, is formed within the endosiphocone [see
text fig.14]. The two conchiolinous bodies are hence in Camero-

ceras brainerdi separated by a layer of gray organic lime

carbonate, the endosiphosheath [see pl.o, fig.1 and text fig.14]. It |

is, however, apparent that in V. belemnitiforane pom
parts are considered as having originated on the outside of the
endosiphocone or to be the direct continuations of the endosipho-
sheath, and the figure [see text fig.4] would seem to bear out this
conclusion.

Germane to this observation of Holm as to the origin of the |

middle part of the endosiphocoleon is the further observation
and resultant conclusion which is cited here [J/. c., p.15, transla-
tion]: “ With the exception of the conchiolinous calcareous
sheath covering the endosiphocone itself, there occur no traces
of such sheaths secreted by the siphon, within the siphuncular
tube. Neither does the calcareous filling show any conical sur-
faces of separation. Since, moreover, the lamellae of the sword-
like structure which proceeds from the endosiphocone form a
direct, uninterrupted continuation of the sheath of the siphon it
must be assumed that the siphon did not secrete the conchio-
linous calcareous sheath until the animal was full grown and no
longer enlarged its conch nor advanced in the siphuncular tube.”
This blade in V. belemnitiforme is supposed to have
reached to the apical end of the siphuncle.

Our observations would indicate somewhat different relations
in C. brainerdi. First the presence in transverse sections

of a series of embracing crescentic conchiolinous sheaths [see _

pl.7, fig.t and text fig.8], which are the remains of the winglike

8

REPORT OF THE STATE PALEONTOLOGIST 1903 315

lamellae formed on the outside of the endosiphocones, demon-
strates that the wings were formed successively on the acute
edges of the flattened posterior part of each new endosiphocone
[see text fig.14], thus leaving with advancing growth and the
formation of new embracing endosiphosheaths this series of
conchiolinous margins behind. As to the middle portion of the
endosiphocoleon we have shown that in our species this is
formed within the apical portion of the endosiphocone or visceral
cone and is hence always surrounded by the endosiphosheath.
The fact of the presence of the anterior portion of this endosipho-
coleon within the endosiphocone indicates, in our opinion, that
it kept growing continuously at its anterior end and during a
greater part of the lifetime of the animal (probably from the
beginning of the nepionic stage to that of the ephebic stage) ;
this growth within the endosiphocone being preparative of an
approaching withdrawal of the animal and the subsequent forma-
tion of a new endosiphosheath. The very gradual disappearance
in our specimens of the endosiphocoleon posteriorly by a replace-
ment of the conchiolinous material by organic lime carbonate,
without a notable diminution in width, is taken by us as a fur-
ther argument of the gradual formation at the anterior end of
the organ and a corresponding gradual absorption posteriorly [see
text fig.13].. With this gradual absorption of the posterior endo-
siphocoleon went hand in hand the new formation of the almost
capillary but strong walled endosiphotube.

While we thus hold that in the species in question the forma-
tion of the endosiphocoleon was not delayed till maturity, but
took place during the entire ephebic stage, we are quite convinced
that maturity with its cessation of siphuncular growth and ad-
vance of the animal led to a longer continued secretion of
conchiolinous matter at the posterior parts of the visceral cone
and in the anterior part of the endosiphocoleon, thus producing
the thick conchiolinous deposit observed in such specimens where
the siphuncle has attained approximately its maximal width,
while in siphuncles of still small diameter these same parts, even
close to the endosiphocone, are provided with much thinner walls.

316 NEW YORK STATE MUSEUM

Holm subsequently [1895, 17 :616; 1896, 18:406] added observa-

tions on V. belemnitiforme without, however, recurring
to his description of the endosiphuncular structure of the Esth-
onian material of Endoceras gladius. He states, how-
ever, that the latter showed that
structure “ remarkably well devel-
oped and preserved ” [/. c., p.617]
and that also in Swedish speci-
mens of V. belemnitiforme
(=gladius) ‘the endosipho=
blade could be observed.

The distinction apparent in our
material between the narrow endo-
siphotube and the wider endosi-
phocoleon, which in apicad direc-
tion becomes a compressed blade,
has not been noticed in the Euro-
pean material and consequently
Holm’s term “ endosiphoblade ”
comprised both the apical blade-
like continuation of the endo-
siphocoleon and the thinner mem-
branes which connect this and
the ectosiphuncle.

place within the siphuncle of Cameroceras brainerdi
during the animal’s advance from the apical cone to the living

chamber at maturity.

REPORT OF THE STATE PALEONTOLOGIST I903 Bw,

The protoconch or earliest embryonic stage is not preserved.t
Its former presence outside of the initial apical cone of the shell
is clearly indicated by the perforation of the apical end and the
opening of the endosiphotube.

The growth stages of the animal of C. brainerdi, as
recognized in the shells, are characterized by
the successive forming of the apical cone, of
the chambered portion, the filling of the
siphuncle and the formation of the final
endosiphosheath [see text fig.16-18]. The
shell (protoconch) in which the embryonic
stage was passed has not been preserved.
The first shell which could be preserved was
am open small cup which grew out into a
long cigar-shaped open conch, the preseptal
or apical cone, or nepionic bulb of Hyatt [see
text fig.16, 19]. It was originally entirely
filled by the animal and its wall consisted
only of the present outer conchiolinous
periderm. The aseptate stage is in Nanno
termed the ananepionic stage by Hyatt. In
C. brainerdi it must have extended

a protoconch. But the finding of the opening of the endosiphotube at

closely related Piloceras (by Foord) leave no doubt that the protoconch in
these forms has not been capable of preservation.

nitiforme has been well depicted by Holm [/. c., p.6, 7] and that.
of the endosiphosheaths by Bather. We therefore take the liberty
of quoting from both of these authors.

The first of these (cameras) originated in this way: On one
side of the upper portion of the visceral sac a circular and almost
inclosed constriction was produced. The fold of the mantle thus
formed deposited shell matter making an inclined wall and a
division of a part of the originally open initial chamber. The
resulting chamber was empty and formed the first air chamber.
The chamber is, thus, bounded by only one septum and in this
case lies behind the wall corresponding to the first septum in
Nautilus. It therefore corresponds to the initial chamber in that
genus. As it here has the same function as the other air cham-
bers, I have termed it the first air chamber, although in fact it is
a remnant of the open initial chamber. Moreover, the second
air chamber is probably formed in part from the anterior portion
of the initial chamber. The visceral sac of the animal was now
divided by a constriction into an anterior and posterior portion.

The anterior portion now forms the actual habitation chamber, but
the great visceral sac also fills the posterior portion. Holm

This writer describes further how, by the formation of more
cameras, the siphonal cord of the animal originates, and con-

cludes: “Hence the siphon of Endoceras ewenmmaneat
forme must have had its origin in a differentiation of the
visceral sac.” ‘This differentiation of the visceral sac by the

formation of several cameras also took place in C. brainerdi
[see pl.6, fig.3 and text fig.17] and may be taken as denoting the
metanepionic stage. Whether the cameras were formed for the pur-
pose of supplying a hydrostatic apparatus to the ever heavier grow-
ing animal, as Holm assumes, or whether they served simply the
purpose of shutting off space no longer used within the conch
by the animal which now grew rapidly forward and expanded
laterally, is here immaterial.t

*The possibility of a different function of the cameras from that of
having been air chambers has been asserted by Jaekel [see Zeitschr. d.
deutsch. geol. Gesellsch. 1902. p.67] and discussed by the writer in a
review of Jaekel’s paper [Am. Geol. 1903. 31:199].

REPORT OF THE STATE PALEONTOLOGIST I903 319

After the formation of several cameras the animal began to
withdraw also from the apical conch and then the formation of
the endosiphosheaths set in, which continued throughout the
neanic or adolescent age. Bather has described this process so
graphically [1894, p.433] that we can do no better than quote

here from him.

We know that in Nautilus and Spirula after the secretion of
the septal necks, the outer coat of the siphuncle, both inside and
outside the region of the septal neck, becomes hardened by cal-
cium carbonate; this gives it a certain rigidity and assists its
retention in the fossil state. The same thing must have occurred

' in the coat of the visceral cone. Now in Piloceras, when the

animal advanced in the shell its viscera naturally followed it, and
by suction the walls of the visceral cone were drawn in so as to
form the narrow and empty siphuncle. At least such would
have been the case had not the stiffness of the outer coat pre-
vented complete yielding of the skin, especially at the posterior
part where the siphuncle tended to begin, but where the coat
was most calcified. It must therefore have happened that the
inner layers of the skin were gradually torn away from the outer
layers. Another stiffening of the skin would take place higher
up and the process would be repeated.

As an explanation of this periodical sloughing it is suggested
that the actual moment of the casting “was after. the emission
of the generative products, when the visceral cone was flaccid;
this explanation coincides with Seeley’s explanation of the origin
of septation itself, but it is not exposed to the objections brought
against the latter.”

Perhaps the fact that the cast of the visceral cone preserved
by the mud filling of the. “Spiess”’ within the last endosipho-
sheath is sometimes of an undulating character, as in the speci-
men reproduced in plate 8, figure 3, and at other times well expanded
and smooth, thus indicating considerable difference in the rela-
tive tension of the wall of the visceral cone, can also be taken
to point to the conclusion that the visceral cone, which in our

form undoubtedly expanded far back into the siphuncular tube,

320 NEW YORK STATE MUSEUM

served principally as the receptacle for the generative organs, which
in Nautilus are situated in the posterior part of the visceral sac.

Hyatt determines the close of the nepionic age in Nanno
aulema with the formation of the first endosiphosheath, after
which in that form the endosiphotube becomes plugged and thus
the open connection closed with the embryo bag or if the latter
had been already destroyed, that with the outside. We have no
evidence that such a process took place in C. brainerdi
after the formation of the first endosiphosheath though here also
the matrix did not enter deeper from the outside into the endo-
siphotube than the thickness of one or a few endosiphosheaths,
but it seems to us that the nepionic stage could not be well con-
sidered as ended till the nepionic bulb or preseptal cone had been
entirely left by the visceral sac of the animal or, in other words,
had become filled with endosiphosheaths.

The tube passing through this first endosiphosheath is still
both endosiphotube and endosiphocoleon, the differentiation be-
tween these two not yet having taken place. Where and when
they become differentiated I am not prepared to say. But this
differentiation is clearly consequent on the widening of the
siphuncle. The latter, as nepionic bulb has only a diameter of
2 mm at the perforation of the first endosiphosheath; it increases
to about 10 mm where the formation of the septa begins, meas-
ures I5 mm where the endosiphocoleon is fully developed [pl.7,
fig.1o| and 20 to 25 mm at its passage into the living chamber of a
mature individual. With the increase of the diameter of the
siphuncle that of the major diameter of the endosiphocoleon
apparently keeps pace. Since, however, as the animal removes itself
more and more from the nepionic conch, only a narrow fleshy band
is left behind, a new narrow tube is secreted by the latter within this
older endosiphocoleon, as we have shown above [see pl.7, fig.2 and
text fig.8]. This is the endosiphotube. As we have indicated in
text figure 13, no differentiation between these tubes has yet taken
place near the apex. If we take the long slender nature of the
apical conch in account, it appears quite probable that the two tubes

REPORT OF THE STATE PALEONTOLOGIST I903 321

do not separate for some time and perhaps not till the neanic stage
is reached.

The neanic stage is one of continuous growth. It begins with
the filling of the nepionic bulb and the accomplishment of the
withdrawal therefrom, and ends with the cessation of the forma-
tion of cameras and the secretion of the last and terminal endo-
siphosheath. Its substages are not clearly defined but since the
differentiation of the endosiphocoleon and endosiphotube takes
place in this stage, it is possible that one substage, perhaps the
metaneanic, will be found to be marked by this differentiation.
The advance of the endosiphocone with the attendant secretion of
endosiphosheaths, forward growth of the endosiphocoleon and,
lagging behind, of the inclosed endosiphotube, persisted during a
great part of the individual lives of the species here under discussion,
as is demonstrated by the considerable length of the conch through
which these structures pass with but slight change. The adolescent
stage and notably its last or its last two substages were hence
remarkably long. The endosiphocoleon is decidedly the most strik-
‘ing endosiphonal structure of this stage.

When finally maturity was reached there were still available to
the animal the living chamber, a very long portion of the wide
and open siphuncle and the endosiphocone, which was closed by
the last and final endosiphosheath. The latter and the last
formed portion of the endosiphocoleon are characterized by
specially thick walls, formed during ephebic age. Further growth
took place only by a lengthening of the living chamber at its
anterior margin.

Gerontic characters have not been observed. |

The following tabulation may serve to bring out the differences

6 Relations of Proterocameroceras to Cameroceras, Vaginoceras and
Nanno

A reference of our species to any of the genera of the Endo-
ceratidae is beset with considerable difficulty. A short historic
review of the varying generic references of the two most nearly
related forms, Vaginoceras belemnitiforme and
Nanno aulema, will demonstrate this. The first form with
a free apical cone or nepionic bulb was described by Holm as

REPORT OF THE STATE PALEONTOLOGIST 1903 B28

apical conch in the genus Endoceras agrees with the form de-
scribed, but added that he was able to trace in several species of
Endocervas the apical portion to a diameter of a few millimeters,
and that in all of them it was simple and conical, and possessed
septa and siphuncle like the remainder of the phragmocone.

In 1894 Clarke described a species with similar apical cone
from the Trenton beds in Minnesota, making it the type of a
mew genus, Nanno aulema [1894, p.205]. In the Minne-
sota report [1897, p.770]| this interesting form has been described
ery elabotately and it has been pointed out there that “the -
continuance of an aseptate condition for a considerable period
in the early history of Nanno is itself indicative of an important
difference from Endoceras (Cameroceras) and Piloceras, inas-
much as this determines it to have been a more elementary

organism than either.’ Holm’s species is here also referred to
Nanno. It is evident that both observers saw in the free apical
cone a differential feature of considerable importance.

On account of Holm’s conservative reference of his species to
Endoceras, the validity of the genus Nanno was questioned by
several authors (Sardeson, Bather). Holm himself discussed
the relations of the endosiphonal structures soon after [1895,
p.616] and came to the conclusion that inasmuch as it is not yet
established that the apexes of all species of Endoceras have not
the same structure as that of E. belemnitiforme, the only
difference between Endoceras and Nanno consists in the unequal
longitudinal and transverse dimensions of the siphonal apical
cone: the siphuncle of Nanno attaining its greatest width within
the apical cone, whence it decreases to the beginning of the
cameration, while in the other Endoceratidae the siphonal apical
cone began undoubtedly very small, and the siphuncle increased
gradually within the chambered conch. For this reason he
adopted the term Nanno for a subgeneric group of Endoceras
and in the following year (1896) described two additional types
of this subgenus, adding also another subgenus Suecoceras. He
redefined the subgenus Nanno, seeing its principal diagnostic
character in the inflated apical cone which corresponds in length
to the combined length of at least three of the oldest cameras,
and which thereafter contracts so rapidly that already within

the third camera the siphuncle attains its normal dimensions.
‘This subgenus is made to include Nanno aulema, Nanno
belemnitiforme and two new smaller tommsaietsmans
parent that we would have to enlarge greatly the definition of
this subgenus if we wished to commit our form, with its very
long but slightly inflated apical cone, to it.

The question is, however, quite differently viewed by Hyatt.
This foremost of the later authors on fossil cephalopods sub-
jected the remarkable type from the Minnesota Trenton to an
independent investigation and came to a different conception of
the genus Nanno [1895, p.1]. It is evident from his discussion
of the relations of Nanno to other genera, as also from his reference
of Holm’s species Endoceras (Nanno)) belecimaian.
forme to Vaginoceras and his later definition of the genus in
Zittel-Eastman’s handbook [p.515], that he did not see in the
large inflated apical cone more than a primitive character of the
nepionic stage, which may be retained in various genera, but
considered the restriction of the “endosiphuncle” (endosipho-
tube) to the apical end as well as the absolute contact of the
shell and siphuncular wall on the ventral side, which leads to a
bending of the sutures apically into a lobe passing around the
siphuncle, as those characters of Nanno which are of generic
importance and differential from the similar genus Narthecoceras.
Thus defined, the genus Nanno becomes restricted to the single
species Nanno aulema and this is’ to bemeaandedmaces
modified descendant of a genus which retains the endosiphotube
throughout life. Insegard to Cameroceras Diaimemamenve
have shown that the endosiphotube passes not only through the
apical cone but also through a large portion of the siphuncle of the
shell to a point near the endosiphocone where it enters the endosi-
phocoleon. For this reason a reference to the restricted genus Nanno
is impossible even 1f the siphuncle were in as close contact with the

6

conch in our species asin Nanno aulema.

The septal necks or funnels of the Valcour form reach only
from the septum of origination to the next apicad of this [see pl.1,
fig.2], and the siphuncle is lined by an inner, thick, continuous
layer (endosipholining). If we, hence, accept Hyatt’s division of the
forms originally comprised tinder Endoceras into the genera Vagino-
ceras, Cameroceras and /indoceras by the criterion of the relative

REPORT OF THE STATE PALEONTOLOGIST 1903 325

length of the funnels, and the presence or absence of the inner

siphuncular lining, our form would have to be brought under
-Cameroceras. We would then be in the peculiar situation of
having three groups of species belonging to three different gen-
era which have in common large preseptal apical cones or
-nepionic bulbs, indicating long continuation of a very primitive
condition in early youth of the forms. In at least two of these
genera these primitive groups contrast with the larger number
of the younger congeners, in which the siphuncle has been en-
tirely inclosed into the phragmocone and the preseptal cone
superseded.

While we do not intend to question Hyatt’s view which
clearly considers the genus Nanno with the scope and definition
given to it by Clarke and Holm, as of polyphyletic origin, and
therefore restricts it to Nanno aulema, we are also con-
vinced that it would not serve the ends of a proper delimitation
of closely related and equally advanced forms, if one would
include in these three genera the forms which clearly represent
an older phylogenetic stage than the genotypes. For this reason
we propose to separate these phylonepionic forms characterized
by preseptal cones from the later and typical phylephebic con-
geners and designate them as subgenera by the prefix “ protero.”

’

We thus have a “ Proterocameroceras’”” represented by Pro-
Berocameroceras brainerdi, which is a Cameroceras
with a large preseptal cone or nepionic bulb; and a “ Protero-
vaginoceras,’ which is a Vaginoceras with a like cone. To the
| latter would have to be referred Endoceras (Nanno)
| Delemnitiforme Holm, while the position of E. (Nanno)
merstula Holm and E. (Nanno) pygmaeus Holm is
uncertain till their siphuncular structures have been studied. As
| the long, stafflike, cylindric conchs would indicate, they may
| belong to neither of the two genera mentioned and be rather
/ genuine Nannos or come under Hyatt’s genus Narthecoceras.
| In the latter case we might have a third genus with “ protero ”
| forms and later forms.

| It is in line with the more primitive character of Protero-
}Cameroceras brainerdi that it occurs in the Beekman-
| town formation; while Cameroceras does not find its principal
‘development till the Black river and Trenton stages.

relationship or common origin of the Proterovaginoceras-Vagi- —

series is therefore not to be doubted. Of these again the Vaginoceras
series has retained the most primitive characters, as is apparent by
the longer septal necks. A Vaginoceras-like form is therefore with
great probability to be considered as the common radicle of the entire — |

7 Similarity between the endosiphocoleon and the proostracum of

belemnites

An inspection of the system of surface lines of the endo-

siphocoleon consisting of forward arching transverse ridges and

longitudinal lines can not fail to suggest the proostracum of the

belemnites; and a study of the relative position of the two organs

and of the probable phylogenetic relations of
the Belemnitidae with the Endoceratidae
makes this comparison seem less farfetched
or strained than would appear at first
glance.

The belemnite shell, when complete, con-
sists, as is well known, of three parts [see
iextyie.20). hese are the rostrum, the
phragmocone and the proostracum. Of
these the rostrum or guard is a later acquisi-
tion which does not concern us here. The
phragmocone is identical with the phrag-
mocone of the early cephalopods which here
however has become entirely inclosed
within the mantle. From the dorsal side
of the last large chamber of the phrag-
mocone (the former living chamber of the
conch) proceeds a broad, thin, somewhat
arched blade, the proostracum, which con-
sists of two stronger longitudinally striated
lateral regions:and a very thin intercalated
dorsal blade. In the typical belemnites this
organ has a size much surpassing that of

the rostrum and phragmocone as in the

lemnite shell: 2, rostrum ; P%,

become reduced,! while, on the other hand, if the Belemnitidae are

traced backward in geologic history, the proostracum becomes

smaller and more insignificant and the Triassic forms do not seem

1The homologies of the different parts of the cuttlebone or sepion of the
Sepia with those of the belemnite shell are not yet clearly established as the

to have yet acquired it, while inversely the phragmocone, as in
Atractites, was still so well developed that this genus was at first
unhesitatingly referred to Orthoceras. Where the proostracum is
fully developed the animal has discarded the phragmocone entirely
as living chamber, and inclosed this former exterior conch within
the mantle whereby the rostrum and phragmocone find their position |
in the posterior end of the animal.

‘The endosiphocoleon, which externally resembles the proos-
tracum, lies within the anterior part of the siphuncle. It is, as we
have demonstrated, formed within the endosiphocone. As now the
endosiphocone contained the posterior portion of the animal (“ vis-
ceral cone” of Bather), and this was inclosed by the mantle, the
endosiphocoleon forming at the posterior end of the visceral cone
was undoubtedly produced by the mantle and since the sur-
rounding endosiphosheath was left behind by the outer mantle,
this more anterior endosiphocoleon is to be considered as
secreted within a mantle flap or fold situated at the posterior
end of the animal. Both the endosiphocoleon and proostracum
are hence formed in identical places.

If we further take into account that while in our Proterocamero-
ceras a large portion of the siphuncle served as chamber of habi-
tation to the animal, and that in the Belemnitidae the animal
had entirely withdrawn from the conch, the different position
of the endosiphocoleon and of the proostracuim relative to the
phragmocone will be seen not to constitute a fundamental dis-
tinction. One might say that the animal in withdrawing first
from the siphuncle and finally also from the living chamber
pulled the endosiphocoleon after it till the latter came to lie in
front of the old living chamber of the phragmocone.

It can not be held that the proostracum is a direct further
development of the endosiphocoleon in view of the fact that the
latter is only found in the early Endoceratidae and could have
no place in the later orthoceracones with their shrunken siphun-
cles, while, on the other hand the proostracum does not appear
till the phragmocone has been reduced to a rudiment in the
Belemnitidae. But since the Belemnitidae, as Hyatt has claimed,.

acs

REPORT OF THE STATE PALEONTOLOGIST 1903 329

can be linked to paleozoic orthoceraconic cephalopods and the
latter again quite probably took their origin from endoceratitic
forms—by way of Baltoceras—and since therefore there is good
reason to consider the Belemnitidae as descendants of the Endo-
ceratidae, the similarity of the proostracum and endosiphocoleon
is probably more than a mere analogy between unrelated forms
due to formation by a like organ (mantle) in the like posterior
position, but it partakes more of the nature of the recrudescence
of an organ discarded before, when a new use
had been found for it within the same race.

It does not matter that the endosiphocoleon r
is a flattened tube and the proostracum only a
blade, as a flattened tube would be readily
changed into a blade under the stress of a
new adaptation.

8 Endosiphuncular structure of Piloceras

We have already anticipated the results of

our investigation of Piloceras in the synoptic

development as Proterocameroceras and (Co Een Seca ae
Nanno. We have also recorded [p.301] that

in Piloceras an endosiphoblade has been observed by Dawson, which
indicates that the endosiphuncular structure may not only be homol-
ogous to that of Cameroceras by the possession and strong develop-
ment of the endosiphosheaths, but also by the character of the
endosiphuncular tubes.

While, however, in the few specimens of Piloceras in which
the apical end has been actually observed, no nepionic bulb
has been found, and the siphuncle has been seen to expand
gradually and.to be inclosed entirely within the phragmocone
[see Foord], we have found that P. explanator Whitfield
at least retains very distinct traces of the nepionic bulb or apical

inflation [see pl. 13, fig.3]. This species points hence clearly

330 IN ENV Ge MORK SiyAwi ye MGhsUpii

to the existence of types which held the same relation to the
phylephebic species of Piloceras as does Proterocameroceras to
Cameroceras; and which would be properly called “ Proteropilo- :
ceras.” If.in:P. explanator. the cameras did not extendjom
one side to near or quite to the apex of this nepionic bulb, we
would not hesitate to make this form the type of the proposed
subgenus. It is evident that a process of acceleration in the
phylogeny of this genus has led to a crowding back of the forma-
tion of septa, which originally was the cause of the contraction
of the siphuncle, to the very apex of the nepionic bulb without,
however, having yet been able to efface all vestiges of this former
inflation of the conch. ‘This also points clearly to the process
by which the nepionic bulbs of Proterocameroceras and Protero-
vaginoceras have become reduced in Cameroceras and Vagino-
ceras, 1. e. by a tachygenetic encroachment of the metanepionic
growth stage on the aseptate ananepionic stage.

Besides the presence of the nepionic bulb, Piloceras exhibits
also in its endosiphuncular structure characters which link it
closer to the Protero-forms of the other associated series, than
to Cameroceras.

The siphuncle is, like the conch, short, conical, with elliptic
to oval section [see pl.10]; the endosiphocone is short and broad
with elliptic upper section, rapidly shrinking to a flat blade at its
narrower end [see pl.13, fig.1,2]. Its cast shows peculiar flutings
arranged in bundles and which, in one specimen, appear to con-
sist of longitudinally arranged pits and strongly remind one of the
similar depressed lines found on the outer conch. Since the latter
are produced by muscular attachment of the animal within the living
chamber, the presence of these scars on the wall of the endosiphocone
seems to me a strong argument for the view that in this primitive
form the visceral cone shared still to a great measure the functions
of the living chamber. We have already seen that in P rotemor
cameroceras brainerdi a large anterior portion on te
siphuncle remained unobstructed by deposits and was evidently
occupied by the animal during its lifetime. In Pilocerasm

explanator this portion of the siphuncle was considerably wider

REPORT OF THE STATE PALEONTOLOGIST I9Q03 Sor

though not longer, for this reason probably amounting to as large
a proportion of the animal as in Proterocameroceras.

Endosiphosheaths and endosiphofunicles. “The endosiphosheaths
were, corresponding to the heavy weight they had to support,
rather stout membranes, reaching in some instances a thick-
MesseOt tinm. They are mostly well preserved, sometimes
¢losely crowded and separated by intervals not wider than .5mm
[see pl.12, fig.5]; but in at least one instance they were also sepa-
tated by an open space of 5mm into which calcite crystals freely
project. Their sections are not evenly curved ellipses, but par-
take more of the nature of polygonal surfaces or are even
bounded by undulating lines. This is due to their being held in posi-
tion by guy ropes or funicles, which we will designate here as
“ endosiphofunicles.” These are of the same nature as the endosi-
phosheaths and appear in sections as dark gray to black pillars of
organic carbonate of lime, often bounded by black lines. They
originated from membranous funicles, in which organic carbonate of
lime was deposited in similar manner as in the endosiphosheaths.
The sections [pl.11, pl.13, fig.3] show them well developed. Several
have been further enlarged to show their relation to the endosipho-
sheaths [see pl.12].

Iieibewere mot for the outward curvature or angulation of: the
endosiphosheaths [see pl.12, fig.1, 2] at the points of connection with
the endosiphofunicles, and for the fact that the outer wall of the
siphuncles passes over these funicles [see pl.i2, fig.2; pl.12, fig.5],
one might be inclined to consider them as worm tubes; specially
where they appear in such great numbers as in plate 11, figure 2. But
in this latter section it will be noticed that the greater number

pass only from the outer wall of the siphuncle to the first

endosiphosheath; while but a smaller number—among these
the remarkable one in the upper right corner which bifurcates
three times [see pl.12, fig.1]—reach the inner endosiphosheath or the
~endosiphocoleon.

In looking over the series of sections, beginning with figure I
[pl.11] we will readily notice that the number of endosiphofunicles

diminishes very rapidly with the shrinking of the endosiphosheaths

332 NEW YORK STATE MUSEUM

toward the apical end. This can be easily explained by the fact
that the endosiphocone in its anterior part needed the most guy
ropes on account of the greater weight of the visceral cone there. |
Therefore also the number of endosiphofunicles diminishes so
greatly from the outer zone to the next, because the outer endo-
siphosheath inclosed a much larger section of the visceral cone
at the plane of the section than the later inner endosiphosheath
did at the same point.

In section I the endosiphofunicles of the outer whorl appear
distinctly as fine tubes with thin conchiolinous walls, their lumen
being filled by a milk-white calcite which
strongly contrasts with the more limpid
calcite crystals surrounding the tubes.
Many of these tubes bifurcate near the
ectosiphuncular wall, one several times.
There is secured by this mechanical con-
trivance a larger base of fixation, which
insures steadiness and freedom fronr
vibrations for the visceral cone during
the movements of the animal.

Whether the numerous endosiphofun-
icles were but a modification of the endo-

siphoblades which, as we have seen, hold

brainerdi and originated by a dissolution of these suspensory
membranes in numerous strands, or are a new formation induced
by the necessity of supporting the heavy visceral cone hanging free
within the broad siphuncle, is a question which we can not con-

NOTE. Wecan not yet determine whether these endosiphofunicles are
homologous to the remarkable verticils of sometimes branching tubuli
which in some species of Actinoceras connect the endosiphuncle with the
ectosiphuncle. Both undoubtedly are quite similar in appearance. The
tubuli of Actinoceras [seee.g. Actinoceras abnorme Hall, N. Y.
State Mus. 2oth An. Rep’t, pl. 18, fig. 10 (copied here after Zittel)] are by
Foord described in Actinoceras bigsbyi [see 1888, p.166] as pene-
trating the siphuncular wall, and it has been suggested by Owen [Pal. 1869,
p.85] that they served for the passage of blood vessels to the living

REPORT OF THE STATE PALEONTOLOGIST 1903 333

clusively answer. But the fact that the endosiphocoleon is also here
in the earliest successive sections of the siphuncle [see pl.11, fig.5, 6]
supported either by continuous membranes proceeding from its
corners or by longitudinal series of closely arranged endosipho-
funicles would argue for a derivation of the endosiphofunicles from
the endosiphoblades. That indeed in the apical portion of the
siphuncle one of the two mentioned modes of suspension prevailed
is to be inferred from the fact that in the above cited succeeding
sections—and as well in the sections found on the other side of the
cutting planes and separated from them by about Imm—the dark
lines which are the sections of the suspensories, retain the same
position throughout.

The arrangement of the endosiphofunicles and endosipho-
blades in the sections [pl.11] shows quite conclusively that the
side of the siphuncle which is the upper in the drawings was
also the upper side during the life of the animal. In the longi-
tudinal section [pl.13, fig.3], which exhibits a series of endo-
siphofunicles the direction of the latter is of still further interest
as giving a hint as to the direction in which the animal carried
its conch. We notice that if we give the endosiphofunicles a
perpendicular position, such as they should have according to
their function as suspensories the conch assumes a direction
which is obliquely ascending under a small angle. This stands in
full accord with what we know thus far as to the dorsal and ventral
sides of the animal; the siphuncle being in contact with the ventral
wall of the conch, while the chambers form on the upper (dorsal)
and lateral sides’ The fact brought out by the outline of a large
specimen given by Whitfield that the ventral side is nearly straight,
membrane of the septal chambers; while Hyatt [1883, p.272] believes
with Barrande that they did not penetrate the true external wall of the
siphuncle. If Barrande and Hyatt are right in this contention and
Hyatt also in his view that the “rosettes” or endosiphuncular deposits
of Actinoceras are strictly homologous to the endosiphosheaths of Endo-
ceras and Piloceras [1883, p.27] the endosiphofunicles of Piloceras
explanator may indeed be homologous to the “tubuli,” and their
function identical, viz, that of suspensories for the siphon, whose outer
membranes have become calcified.

"In the section the chambers of course appear only on the upper
(dorsal) side.

334 NEW YORK STATE MUSEUM

while the dorsal one is very convex, or in other words, that the |

ventral side appears as a base, all growth taking place in dorsal direc-

tion, tends also to support the view that the conch was carried slightly —

oblique and at rest placed in a horizontal position.

It is interesting to note in this connection the views
held by prominent zoologists as to the polarity of the
Cephalopoda. Huxley, Lancaster and Lang give the
original cephalopod the position shown in the diagram-

matic figure reproduced here from Lancaster, while Ver-

Endosiphocoleon. It remains to us to trace the development of
the endosiphocoleon of the siphuncle of Pilot emas sles
planator, which can be best done by reference to the series
of sections I-7 on plate 11.

We have already stated that the endosiphocone becomes flatter

as it approaches its posterior end till at its termination it is five ©

or more times as broad as high [see pl.13, fig.2]. From this end
proceeds the endosiphocoleon, a flat sheathlike canal, which is nearly
as wide as the innermost endosiphosheath; in section I by a sec-
ondary fracture apparently still wider. The longitudinal section
[pl.13, fig.3] shows this endosiphocoleon in a young specimen, cut
through its shorter axis. It demonstrates that the endosipho-
coleon possesses a thin conchiolinous wall which extends through
the last endosiphosheath into the cavity of the endosiphocone ;

and hence was here not formed as a continuation of the external

conchiolinous layer of the endosiphosheath, but within the apical end

REPORT OF THE STATE PALEONTOLOGIST 1903 335

of the endosiphocone. It is hence identical in origin with the
endosiphocoleon of Proterocameroceras brainerdi.

From its lateral ends proceed the endosiphofunicles described
above, apparently mostly in longitudinal series. Corresponding to
the vertical contraction of the siphuncle the section of the endosi-
phuncular canal is broader than high and its lateral ends coalesce
into a conchiolinous blade. As the central portion retains its full
lumen, the section becomes in this specimen at first very broadly
triangular [fig.4| and finally (through fig.5, 6) a low triangle. The
apical termination of this endosiphuncular canal is not shown in the
specimen here sectioned because the ventral portion of the
siphuncle has been worn away. ‘There is, however, not more
than 11mm wanting of the total length of the siphuncle, and it
is therefore evident that no endosiphotube with distinctly cir-
Miameconcniolious wall passes, as in Proterocamero-
Peteommirainerdi, through a large apical portion of the
siphuncle. The coloring of the calcite within section 4 suggests
perhaps [see enl. pl.12, fig.3] that also here only a lumen with circu-
lar section may have remained open within the endosiphocoleon, but
the next section (5) fails entirely to show any inclosed tube.

We have hence no evidence of the formation of an endosiphotube
Peeetoceras explanator, but do not doubt that where
the siphuncle becomes longer and more tubular instead of remaining
short and broad as in this species, an endosiphotube may be formed,
as indeed it has been found in other species of Piloceras.

The wings of the endosiphocoleon in Proterocamero-
weirs Dtainerdi, which originate from a deposit of
conchiolinous matter on the outside of the endosiphosheath and
which there form such a striking feature, have been observed in
but one instance, where the apical portion of the siphuncle is
extremely broad and flat and the lateral margins of the endosipho-
sheath form hence acute angles. They seem for this reason to have
been strengthened by conchiolinous deposits.

Among the eight species of Piloceras which have thus far been
described, one, P. newton-winchelli Clarke [1897, p.767],

336 NEW YORK STATE MUSEUM

from the Shakopee formation in Minnesota is of special interest in
relation to the genetic history of this genus and in our opinion stands
at the opposite end of the series from P.explanator. While
in the latter the ectosiphonal wall distinctly consists of the
coalesced reflexed margins of the septa (septal necks), Clarke’s
careful description and figures [see fig.25] demonstrate that in
P. newton-winchelli the funnels or septal necks are
only very short and the siphuncular wall is distinctly formed by
a secondary formation, “the annuli’’.1
If we adopt Hyatt’s fundamental divi-
sion of the Nautiloidea, we find the
genus Piloceras brought under the Holo-
choanites which are characterized by the
extension of the funnels from one sep-
tum to the next preceding or beyond.

stage found in the other Piloceras forms, to the later Orthoceras
stage. The relation of this form to the typical Piloceras appears to
us identical with that of Hndoceras bureh apc Wowie
to the true Endoceras, the latter being a species which, while retain-
ing the habit of an Endoceras has, as Holm has shown [1897, p.171]
the ectosiphuncular structure of an Orthoceras. Holm proposed the
genus Baltoceras for this form, a genus which is considered by
Hyatt as the first and most primitive of the genera of Orthoceratidae.

I]t is doubtful whether these annuli or siphuncular segments of the Ortho-
choanites form a homologue to the continuous “ endosipholining ” of Camero-
ceras, as it would appear at first glance. The endosipholining is considered
by Hyatt as composed of the upper unresorbed ends of the endosiphosheaths,
while the siphuncular segments find their fullest development where, on
account of the reduction of the siphuncle; no more endosiphosheaths are
formed. Nor is any genetic connection between the segments and the
endosiphosheaths apparent in text figure 25.

Summary

meine conch ef Cameroceras brainerdi from the
Upper Beekmantown formation begins with a long slender pre-
septal cone or nepionic bulb, which terminates anteriorly with a
slight constriction where septation sets in.

2 The nepionic bulb and the middle (neanic) portion of the
siphuncle are filled by endosiphosheaths, while the anterior
(ephebic) portion is empty.

3 The empty anterior portion is closed in apicad direction by
the final endosiphosheath, which incloses the endosiphocone

(visceral cone). From this last formed endosiphocone a broad,
flattened tube with conchiolinous walls extends backward, for |
which the term “endosiphocoleon” is here proposed. This |
forms within the endosiphocone preparatory to a further with-
drawal of the animal and the formation of a new endosipho-
sheath. In apicad direction it changes into a blade, consisting
of two lamellae, disappearing gradually by being altered into
organic calcium carbonate and becoming confluent with the cai-
cium carbonate filling of the siphuncle. The endosiphocoleon
grew hence at its anterior end and was absorbed at its posterior
end or vanished there by secondary alteration into lime
carbonate.

4 In the same measure as the endosiphocoleon disappears, a
capillary conchiolinous tube, the endosiphotube, becomes promi-
nent. This forms within the endosiphocoleon by the posterior
contraction of the siphon. It extends to the apical end of the
nepionic bulb, where it empties (into the protoconch which is not
preserved):

5 The endosiphocoleon is flanked on both sides by conchiolin-
ous wings, having a crescentic section. ‘These form on the out-
side of the angles of the flattening endosiphosheaths and are |
hence separated from the endosiphocoleon by the organic lime
carbonate composing the endosiphosheaths.

6 The posterior portion of the empty, ephebic siphuncle is lined
by the endosipholining, the anterior portion only by the septal necks
or funnels.

7 The endosiphocone, endosiphocoleon and endosiphotube are
held in position by (mostly three) radiating suspensory mem-
branes (endosiphoblades), which affix the endosiphosheath etc.
to the preceding endosiphosheath and the ectosiphuncle.

8 The presence of a preseptal cone or nepionic bulb in an early,
otherwise typical, Cameroceras (C. brainerdi),—while in
the later species of Cameroceras the nepionic bulb has disappeared,

stage of development with a prominent nepionic bulb, which fact is
of sufficient phylogenetic importance to require recognition by
assigning these forms to’subgenera (Proterocameroceras, Protero-
vaginoceras and possibly Proteropiloceras) of their respective
genera. |

bulb is still recognizable by an inflation of the apical portion of
the siphuncle, which by tachygenesis has become inclosed in the
phragmocone.

11 The endosiphocoleon extends without becoming absorbed
to or nearly to the apical end. This results from the wide short
form of the siphuncle.

12 The endosiphosheaths and endosiphocoleon are held in posi-
tion by numerous suspensory funicles (endosiphofunicles). These
proceed from angulations of the endosiphosheaths and frequently
divide in outward direction.

13 The arrangement of the endosiphofunicles on the side oppo-
site the flat side of the conch, where siphuncle and conch are in
contact, indicates that this latter side may have been the ventral .
one and that the conch was carried in a subhorizontal, slightly
ascending direction.

14 Piloceras newton-winchelli Clarke is by the
structure of its ectosiphuncle not a holochoanitic form as the
other congeners, but an orthochoanitic form and represents a
genus (Clarkoceras) which holds the same relation to Piloceras
as Baltoceras to Endoceras.

NOTES ON THE: SILURIC OR ONTARIG]SEGH@i om
EASTERN SING YORI

BY C. A. HARTNAGEL

The Ontaric section of central and western New York, as
developed west of ‘the Helderberg is subdivided into 10:
divisions,! and it is from this section of the State that all but
one of the locality names applied to these divisions are derived. |
Each of these divisions is more or less distinctly characterized
by differential lithologic features and all are fossiliferous.?

On the east side of the Helderberg and including the section
extending from Ulster county southwest to New Jersey, the
Ontaric lacks’ several members of the group, while the fossils
found are of an age not earlier than late Salina, the lower mem-
bers of the Ontaric where present being entirely without fossils.
The fact that the Manlius and Rondout formations alone of the
entire Siluric series have stratigraphic continuity across the Hel-—
derberg, has left the outcrops of the Siluric rocks in New York
divided into two nearly distinct geographic areas.? |

While the main purpose of this paper is to bring out the rela-
tions of the Cobleskill formation as developed in eastern and
southern New York, it will also attempt to show certain relations.
of the lower members of the Ontaric formation in so far as they
have come under the observation of the writer. The lower members
of the Ontaric section in this portion of the State are entirely unfos-
siliferous and confusing in their lithologic features, and it will still
require considerable study to accurately locate their correct position _
in the geologic series. This condition is brought about by the dis-
covery that the Cobleskill horizon is above the Salina deposits, a
fact which suggests that the Shawangunk grit and red shales above |
it may possibly represent a later age than that to which they have |

been usually referred.

2 While the Salina beds are sometimes regarded as being nonfossiliferous, it
will be observed that the Salina as now defined includes at its base the Pitts-
ford shale and at its top the Bertie waterlime. Both of these formations are’
characterized by an Eurypterus fauna.

3A third area is developed in Rensselaer county. The Ontaric is here repre-
sented by a single member known as the Rensselaer grit. This is generally
considered the equivalent of the Oneida or of the Shawangunk grit.

REPORT OF THE STATE PALEONTOLOGIST 1903 343

Shawangunk grit and conglomerate

The lowest member of the Ontaric section in eastern New
‘York is the Shawangunk grit. This designation was first ap-
‘plied to the formation by Mather,’ the term being derived from
the mountain area of that name, which extends from near High
Falls in Ulster county southwest through Orange county and
beyond the limits of the State. The Shawangunk grit, wherever
‘the contact has been observed, is seen to rest unconformably on
‘the Lower Siluric shales. The Shawangunk grit is generally
correlated with the Oneida conglomerate, the latter term often
‘being applied to it. Of these two formations the Shawangunk
grit has the greater development, the thickness varying from
less than 50 feet in parts of Ulster county and gradually increas-
‘ing in thickness to more than 200 feet within a few miles. The
‘Oneida conglomerate in its type section has a thickness of from
15 to 20 feet and in its western extension it gradually grades
‘into a sandstone known as the Oswego sandstone, which in
Oswego ccunty has a thickness of more than Ioo feet. Both
the Oneida conglomerate and the Oswego sandstone are transi-
‘tional into the Medina sandstone above. ;

It will thus appear that while we may consider the Medina as
directly following and transitional from the Oneida in central
New York, the sequence of events following the deposition of
‘the Shawangunk grit in eastern New York has never been satis-
factorily established. While for many years the red shales lying
-above the Shawangunk grit in Ulster county and further south
have been generally correlated with the Medina of central New
York, no proof has ever been set forth to establish their identity
with any degree of certainty. Mather? in the final report of the
first district, the western limit of which was as far west as Her-
‘kimer county, did not definitely correlate these red shales, though
he was inclined to refer them to the Medina. He says, “The
-observations made do not render it certain whether these red

rocks are equivalent to the Onondaga salt group or the Medina

sandstone; but it is thought probable, from some of the mineral’
characters, no fossils having been seen, that they belonged to»
the epoch of the Medina sandstone, and that the subjacent Shaw--
angunk grit is equivalent to the gray sandstone (=Oswego)
instead of the Oneida conglomerate.”
While it is known that Mather! recognized and designated a

é

formation in eastern New York as “ coralline limestone ” which
recently has been shown to be identical with the Cobleskill
limestone, it is evident from the above citations that Mather
could not have regarded it as of Niagaran age, or he would not
even have suggested the possibility of the underlying red shales.
being of Salina age. For many years following the publication |
of Mather’s report the section under consideration was not much |
studied. The discovery, however, by Dr Barrett, of Cobleskill
fossils near Port Jervis in strata which lie above the red shales, —
and the studies of Lindslay of the same formation at Rondout,.
left little doubt as to the continuity of these rock masses in the
intervening section, and since the Cobleskill at that time was.
correlated with and generally accepted as the equivalent of the
Niagaran formation as developed in western New York, it served
for the time being as apparently conclusive evidence that the
underlying shales could scarcely be correlated other than with
the Clinton and the Medina, or at least it was not thought they
could possibly represent the Salina. As we now know that the
Cobleskill limestone is of an age later than the Salina, the age
of the red shales together with the so called Clinton quartzite
lying above the Shawangunk grit again comes into question,
since both the Salina and the Medina are below the Cobleskill.
As no fossils have been found in the red shales, a feature which
contrasts them with the Medina of central New York, it is evi--
dent that in any attempt to correlate these red shales, evidence
must be had from other sources.

It was early shown by Vanuxem? and Hall? that in central
New York the passage from the Oneida to the Medina was a-

gradual one, the conglomerate or the sandstone (Oswego) being
transitional into the Medina. The lower portion of the Medina
throughout the central portion of the State contains pebbles abun-
dantly and is also characterized by an oblique laminated structure
which is well shown in the exposures of the Medina in Herkimer
county. On the other hand the base of the red shales (=High Falls
shales) above the Shawangunk grit in Ulster county and far-
ther southwestward do not possess the transitional features
ascribed to the Medina of central New York. In the eastern
section these shales are entirely devoid of pebbles, generally of
a bright red color and uniform in character, specially near their
base. On exposure to the atmosphere they break into small
angular fragments which are easily washed away leaving the
sloping surface of the conglomerate beneath clean and white.
In small protected areas on the western face of Shawangunk
mountain, where the agencies of weathering and erosion have
been less severe and the shale, perhaps, of a firmer texture, a
number of isolated patches of these red shales occur. They
are, however, easily removed and the underlying conglomerate
brought to view. On the farm of Patrick Winn at High Falls
the contact of these red shales with the conglomerate is favor-
ably shown. At this place the shales formerly were quarried
and used for making paint. They here retain their characteristic
features down to the conglomerate. It is evident then that there
is a very marked change in the character of the sedimentation
following the conglomerate, suggestive of a hiatus at this point.
Nowhere in central New York has the base of the Medina the
features presented by the red shales of this section. In litho-
logic features they are more like the Vernon red shales of the
Salina than any bed of the Medina, though in the upper portion
of the Medina there are beds of red shales of a somewhat similar
character but more arenaceous. Such beds can be favorably
examined at Lewiston on the Niagara river.

A study of the overlaps on the west side of the Helderberg
shows that the Salina shales extend farther east than does the
Medina, and since the period was one of increasing submergence,

346 | NEW YORK STATE MUSEUM

it is but natural that we should expect to find in eastern New

York manifestations of Salina time rather than the Medina and ~

the Clinton. The so called Clinton quartzites (=Binnewater quart-
zites) lying above the red shales were so designated because they
are in some respects similar to the Clinton formation of western
New York, and probably also because of their similarity to the green
shales with iron pyrites lying beneath the Cobleskill in Schoharie
county which were formerly also correlated with the Clinton. In

this connection it is interesting to note that the view as given above

was held by Mather.!

With this correlation in view, it follows that, if the quartzite
with the iron pyrites in eastern New York is the equivalent of
the green shales of the Schoharie section then the quartzite of
eastern New York is Salina and not Clinton, since it is known
that the green shales of Schoharie county are of an age not
earlier than late Salina. South from High Falls the quartzite
below the Wilbur limestone becomes more calcareous and of a
shaly nature. At Accord, a few miles south from High Falls, the
shales are seen in the cut on the Ontario & Western Railroad.
At this place the beds are light colored, soft, argillaceous shales
with considerable mineral matter. They are exposed for a thick-
ness of 18 feet. Southwest from this point there are no favorable
exposures for the examination of these shales in New York. ;

If we regard the red shales above the Shawangunk grit and con-
glomerate as Salina in age, it is quite probable that the Shawangunk
in this portion of the State is much later than has been generally
supposed. Recent studies indicate that the Shawangunk pest
the invading basal member of the Salina series.

Poxino Island shale
This is the term applied to irregular bedded, buff colored;
calcareous beds which are exposed just across the New York
State line in the Nearpass section in New Jersey and farther
south. At the Nearpass section they are but obscurely shown

for a thickness of 1 foot, and they here form the lowest member

that can be observed in the Nearpass section. These shales have
meeepeen identiied with certainty in New York State. Near
~ Cuddebackville a few miles north from Port Jervis, somewhat
similar shales, but containing iron pyrites, have been observed.
‘They hold a position below the Decker Ferry formation, but
the contact with the Decker Ferry could not be observed. The
shales below the Decker Ferry as recognized at Accord have a
somewhat similar appearance to the Poxino Island shale. In
this section the Bossardville limestone which lies between the
Poxino Island shale and the Decker Ferry formation could not
be observed. It is probable, however, that the Bossardville
limestone has failed by thinning out before this section is
teached. The age of the Poxino Island shales has as yet not
been definitely established, but they probably belong to the

Salina.
Bossardville limestone

No outcrop of this formation has been recognized in New
York State, though it probably extends from New Jersey into
Ulster county. At the Nearpass section, 3 miles south of Port
Jervis, its entire thickness is shown to be slightly more than 12
feet. It directly overlies the Poxino Island shale and in litho-
logic features it much resembles some thin banded layers of the
Manlius limestone. This is the lowest member of the Ontaric
formation in this section that is fossiliferous, but even this is
only sparingly so. Leperditia altoides Weller is found
quite abiindantly in several of the thin layers in the upper 2 feet
of the limestone. Besides the Leperditia a single individual of
the genus Oncoceras was found. ‘This species is in some respects
himmar to O. ovoides Hall, but is smaller and probably a
distinct species. The Bossardville limestone is regarded by the

writer as a late representative of Salina time.

Decker Ferry formation
The term Decker Ferry formation as recently applied by Wel-
ler in the New Jersey section includes all the strata between
the Bossardville limestone and the Rondout waterlime. The

upper 6 feet of the formation as described by Weller may, how-

348 NEW YORK STATE MUSEUM

ever, be definitely correlated with the Cobleskill limestone, as
typically developed in Schoharie county. The lower part of the ©
formation is the equivalent of what has been termed Salina
waterlime and Wilbur limestone in a previous report?
FOSSILIFEROUS SECTIONS

The following fossiliferous sections extending from the well
known locality of the Decker Ferry formation, as exposed 3
miles south of Port Jervis, and extending northeastward into
Ulster county will serve to show the stratigraphic relations of
the fossiliferous beds up to the Coeymans limestone.

Nearpass section 3 miles south from Port Jervis N. Y.

1 Poxino Island shale. In an excavation a little distance above
the base of the cliff there is an exposure of a bed of buff shale 1
foot in thickness. This exposure is being rapidly covered by
talus. No fossils.

2 Bossardville limestone. Thin banded limestone of alternate
light and dark colored laminae. On account of the shaly nature
of the rock, the entire thickness of slightly more than 12 feet can
be readily examined; Leperditia altoides Weller found
abundantly in layers near top; Oncoceras cf. ovoides Hall
the only other fossil observed.

3 Decker Ferry. The lower 24 feet of this formation consists
of several layers of hard crystalline limestone with some shaly
beds. This portion of the section is highly fossiliferous and
from the specially characteristic fossil Chonetes jersey-
ensis Weller, it has been designated the Chonetes jerseyensis
zone. Though found in the other zones of the Decker Ferry
formation and rarely in the Cobleskill limestone of Schoharie
county, Atrypa reticularis Linm is very abundant in
the lower portion of the Decker Ferry, and farther north in
Ulster county it is so plentiful as to make a distinct band in the
Wilbur limestone.

4 Decker Ferry. Red crystalline limestone 2 feet. This layer
is characterized by the species described by Weller as Ptilo-

1N. Y. State Paleontol. An. Rep’t 1903, p. 1142.

a

REPORT OF THE STATE PALEONTOLOGIST I903 349

dictya frondosa and is designated as the Ptilodictya
frondosa zone. This limestone by reason of its distinctive
lithologic and faunal features can not be confused with any other
bed. No outcrop of this rock has been observed in New York.

5 Decker Ferry. The 15 feet of limestones and shales lying
above the red crystalline limestone have no characteristic fossil
to mark it as a distinct zone. Rhynchonella? lamellata
occurs abundantly, but this fossil has a considerable vertical range
and in some sections extends up into the Rondout. This zone may
be regarded as transitional into the Cobleskill limestone. Its
stratigraphic position is that of the lower cement bed of the
Rondout section, but in the Nearpass section there are no cement
beds.

6 Cobleskill formation. Six feet of limestone characterized by an
apmudance of corals, such as Prismatophyllum, ine-
foes lalysites catenulatus Linne. This zone
by reason of similarity in lithologic features and fossil con-
tents may be definitely correlated with the Cobleskill limestone
of Schoharie county where it is typically developed, with a thick-
Hess Of 6 feet.

7 Cobleskill formation? Above the 6 feet of limestone desig-
nated the Cobleskill there are 4 feet of limestone in thin beds
separated by shaly layers. Though containing Cobleskill fossils,
the abundance of ostracodes present indicates a change in the
nature of sedimentation, due perhaps to the introduction of brackish
water conditions which lasted throughout Rondout time.

8 Rondout formation. Above the Cobleskill limestone in the
Nearpass quarry section there are 39 feet of shales and lime-
stones. In general lithologic features this formation resembles
the Rondout as developed in New York State, but the cement
bed so characteristic at the base of the formation farther north
is absent here. With the exception of several species of Leper-
ditia, fossils are extremely rare. Future studies may show that
the 4 feet of limestones and shales at the base of this formation
and which have been provisionally included with the Cobleskill
belong to the Rondout.

350 NEW YORK STATE MUSEUM

Q Manlius limestone. This formation which is nearly 35 feet
thick carries a typical Manlius limestone fauna. The fossils in
some cases are not well preserved. ‘This is specially true of
Tentaculites gyracanthus Eaton, of which well pre-
served specimens are rare. From the Nearpass section, however,
on the reverse side of a thin slab collected for specimens .of
Megambonia aviculoidea Hall, there was@ioundg
Tentaculites gyracanthwus equally as abuudantiacam
the sections farther north in New York State. They are how-
ever in a very poor state of preservation and may readily be

passed unnoticed.
ORANGE COUNTY SECTIONS

In the section a short distance southeast of Port Jervis at
Carpenters Point neither the Cobleskill nor the Decker Ferry
formations can be observed, though several members of the Hel-
derbergian are shown at this locality. About 2 miles farther north
from Carpenters Point the Erie Railroad crosses these formations
but they are all too deeply covered to show any outcrops.

The best place in Orange county for the examination of the
Cobleskill and Decker Ferry formations is in the valley of the
Neversink about 8 miles north of Port Jervis and 1 mile east of
‘Cuddebackville. Here there are a number of parallel ridges
which include not only the Cobleskill and Decker Ferry forma-
tions, but the Rondout and Manlius together with the Helder-
bergian members of the Devonic.

About 1 mile southeast from Cuddebackville there is an old
quarry with a limekiln near by. The beds here are nearly ver-
tical, and just to the east of the quarry the Cobleskill together
with the upper part of the Decker Ferry formation is shown.
‘The rock is here much sheared and is traversed by mineral
veins. This outcrop of the Cobleskill and others in the vicinity
of the same horizon are noted by Ries! and are included by him
with the Tentaculite (Manlius) limestone. The lower part of

this outcrop is not favorable for collecting but in the upper part

The Cobleskill limestone is obscurely exposed in the field be-
yond, where also were found the thin limestone bands crowded
with Whitfieldella sulcata Van. and@)Sipiguies
vanuxemi Hall, and which mark the upper limiteer cme
Cobleskill.

Passing from this station northeastward into Sullivan county |
no outcrops of the Cobleskill have been observed. Throughout a
Sullivan county there is but little opportunity for the examina-
tion of the Siluric and Helderbergian rocks. The cliffs so promi-
nent north.from Port Jervis between the Neversink river and
Shawangunk mountain become low in Sullivan county and almost
entirely disappear. Outcrops in the valley are but rarely seen.
There is an old limekiln on the land of John Olcott a short distance

north from Wurtsboro located near the outcrop of the Esopus
shales. There is however no outcrop of limestone in the vicinity,
the rock used for burning lime being gathered from the fields.
Just over the county line north from Spring Glen station! in
Ulster county, there is an old quarry near the east bank of the
now abandoned Delaware and Hudson canal. The rock as here

exposed is a thin bedded limestone with some layers of shale and
appears to belong to the lower portion of the Manlius.

Two miles southwest from Ellenville there is a small but con- :
spicuous outcrop of Helderbergian limestones which rise above
the general level of the valley. Whe outcrop is near Sanboum
ereek on the land of L. F. Hall. Lime is burnt at this place base
only in small quantities. A similar outcrop is seen at John Horn-
beek’s quarry a short distance south of the Eastern Reformatory

‘This outcrop and the two following are noted by Mather. Geol. N. Y.
TS Wisty long pAs22-3 2)

REPORT OF THE STATE PALEONTOLOGIST 1903 353

at Napanoch. The presence here of Leptaenisca adnas-
eens Hall & Clarke is indicative of the New Scotland age of
these beds.

In passing northward from Ellenville the first outcrop favor-
able for the examination of the Cobleskill is on the land of
Joseph Chipp % mile north from Kerhonkson. The rock is
shown in the base of an old quarry on the left of the highway
leading to Accord. The locality is not favorable for collecting
but the following fossils were obtained.

1 Favosites helderbergiae var. prae- { 4 Spirifer corallinensis Grabau
cedens Schuchert 5 S. cf. vanuxemi Hall

2 Atrypa reticularis Linné 6 Whitfieldella nucleolata Hall

3 Orthothetes interstriatus Hall 7 Leperditia jonesi Hall

The Rondout is not well shown in this section. About 16
feet of Manlius limestone is exposed in the quarry of Lincoln
McConnell on the opposite side of the highway. The combined

‘thickness of the Rondout and Manlius at this place is 70 feet.

One of the most favorable localities for the examination of

‘the Decker Ferry and Cobleskill formations is in the cut of the
recently constructed Kingston branch of the Ontario & Western

Railroad, % mile southwest from Accord. The railroad passes
in succession over the formations, from the shales underlying
the Decker Ferry to the Coeymans limestone which is exposed
near the station at Accord, but only the shales, the Decker Ferry
and the Cobleskill are shown in the cut. The shales which are
exposed in this cut are considered to be of Salina age and are
exposed for a thickness of 18 feet. The beds are soft, argillace-
-ous with bands of mineral matter and so far as known without fossils.

The Decker Ferry formation is 12 feet thick and in layers
which are quite massive. The basal layer is arenaceous and
eradually changes and becomes more calcareous above. The
formation is fossiliferous throughout. The red crystalline lime-
stone which forms such a conspicuous layer in the Nearpass sec-
tion has not been observed here, and whether its absence is due

‘to thinning out or failing through overlap of the succeeding

-deposits, in which case only the upper part of the Decker Ferry

354 NEW YORK STATE MUSEUM

formation would be represented in this section, has not been
determined. It seems probable that since the period was one of
submergence, the latter view is more nearly correct, though in
this section Chonetes jerseyensis, which is the char-
acteristic fossil of the lower Decker Ferry formation in the
Nearpass section, is here equally as abundant and in size averages
larger. This fossil, in the cut at Accord, is sometimes so plen-
tiful as to make a band a fraction of an inch in thickness. From

the railroad cut the following species were obtained.

1 Favosites sp. - 7 Rhynchonella deckerensis lVeller
2 Monotrypa corrugata Weller 8 R. litchfieldensis Schuchert

3 Rhynchonella? lamellata Hall 9 Spirifer cf. corallinensis Grabau-

5 Chonetes jerseyensis Weller 11 Stropheodonta bipartita Hall

6 Rhipidomella cf. preoblata Weller | 12 Pterinea emacerata Hall

A favorable place for the collection of fossils from the basal
arenaceous layer is at Fiddlers Elbow on the Delaware and Hud-
son canal a short distance from the railroad cut. At this place
the canal is partly excavated in the shales and the limestone is
found a little higher up by the canal bank. At some points the
underlying shales have weathered away leaving the limestone
above as a slightly projecting ledge. From the basal arenaceous.
layer the following species were obtained.

1 Favosites sp. 4 Gypidula cf. galeata Dalman
2 Monotrypa corrugata Weller 5 Stropheodonta bipartita Hall
3 Atrypa reticularis Linné 6 Spirifer sp.

At this place a number of rather poorly preserved specimens.
of a pentameroid were found. They approach closely Gypid-
ula galeata of the Coeymans limestone and may prove to
be identical with it.

The Cobleskill limestone is exposed a little higher near an old
limekiln. The rock is here much weathered and fossils are
readily obtained though not in a well preserved state. A feature
of the collection from the Cobleskill obtained at this point is
the large number of gastropods and cephalopods found, and the
fauna is more nearly like the normal fauna of the Cobleskill of
Schoharie county than at any other section that has been studied.

In the railroad cut the Cobleskill is also exposed but not so
favorably for collecting as in the last named locality. The thick-

* in the cut is about 6 feet. The contact with the Rondout
could not be observed at this station. The formations exposed
) at Fiddlers Elbow and in the railroad cut can be readily traced
to a short distance east of Accord, where they form a clearly

defined cliff. The base of the cliff is mostly covered with talus

; and the outcrops are not favorable for collecting.

In the vicinity of Accord no beds suitable for making cement

“have been observed. This place is but 6 miles from High Falls

' where cement has been quarried from the dark Rosendale beds
_ which at the latter place have a maximum thickness of 22 feet.

mit will thus be seen that the lower cement bed so extensively
: developed in the Rosendale region and which extends to High
5 Falls, becomes too calcareous to bé used for cement betore
_ Accord is reached. At Rosendale the lower cement bed, with
the exception of Leperditia, which is sometimes found near the

base, is so far as known, entirely without other fossils. When
showever High Falls is reached the cement bed, specially near
; its base, becomes fossiliferous. From the cement rock at this
@ueee some corals, Atrypa reticularis*Linné, Ilionia
Semmimata Hall,and Nucleospira cf. ventricosa Hall
have been obtained. The Cobleskill can be readily recognized

Mear the brink of the falls on both sides of the stream. The
_ cement bed is about 14 feet thick, and at its base and resting on
the quartzites below, is a fossiliferous band of shaly limestone 4
to 10 inches thick, in a previous report!“teferred to the. Wilbur

_ limestone, which in the type section, as at High Falls, underlies

N. Y. State Paleontol. An. Rep’t. 1903. p.1146.

350 NEW YORK STATE MUSEUM

the lower cement bed. A good view of the falls is given by ~
Darton’ in his report on the Geology of Ulster county. At High |
Falls the thin layer above referred to contains unmistakable Decker 4
Ferry species, the most characteristic of which is Monot rypa 4
corrugata Weller. The fauna obtained follows: |
I Favosites sp. 5 Orbientorle! cf. tenuilamellata
2 Monotrypa corrugata Weller Hall ;
3 Atrypa reticularis Linné 6 Orthoceras sp. undet.
Ae Prermnuiea emacerata Conrad

The study of the sections at High Falls and Accord2and a 4
comparison of them with the sections farther south indicate |
quite clearly that the lower cement bed at Rosendale and the 7
lower cement bed and Wilbur limestone at High Falls are of |
the same age as the Decker Ferry formation as developed to the |
southwest. of these localities. ,It is also believed thar eae j
cement bed which holds the stratigraphic position of the Bertie water- f
lime of western New York is of the same relative age as the latter, i;
both underlying the Cobleskill limestone. In western New York 2
the Bertie limestone is characterized by an Eurypterus fauna. The ;
absence of Eurypterus from the formation in eastern New York is ;
attributed to the fact that this section of the State belonged to
another sea-province. We therefore propose to meet this difference t
in the east by introducing for the lower cement bed in Ulster and |

adjoining counties the term Rosendale cement. The transition to a
the Cobleskill from the underlying fossiliferous beds in eastern New 1
York has been shown. In western New York the transitional fea- |
tures are somewhat more complex and obscure. Still enough is |
known to show an intimate relationship between the Cobleskill and
Bertie formations. | |

In the Eurypterus-bearing waterlime beds of western New
York (Bertie) Cobleskill fossils are rarely found associated with ©

Eurypterus. However Orthothetes interstriatusm
Hall and Leperditia scalaris Jones are occasionally §

found on the same slab with Eurypterus. In beds which are ©
strictly referable to the Cobleskill and which contain Cobleskill |
fossils the writer has never found an Eurypterus. The condi- .

aN. Y. State Geol. ‘13th An. Rep’t. 1894. pl. 10 facing p.342.

REPORT OF THE STATE PALEONTOLOGIST 1903 357

‘tions however which are found and which show the intimate
relation of the two formations are as follows.

_ In western New York usually underlying the Oriskany sand-
stone is found- the Cobleskill dolomite which at Buffalo, Dr
'Grabau! has shown, contains a fauna similar to the Cobleskill
é and which later studies have shown to be identical with the
Cobleskill. In Ontario county at Phelps below the Oriskany
Ssandstone is found the Cobleskill or “bullhead” rock as it is
known in western New York. This rock here and farther west
at Victor and beyond, contains the Cobleskill fauna. Beneath
‘the “bullhead” rock in Ontario county in a thin bed of water-
lime, fragments of Eurypterus are found and at Victor a large
“number of fragments from this horizon were obtained. Beneath
‘this layer of waterlime in Ontario county we find again in the
: dolomite layer another Cobleskill or “bullhead” fauna in which
Lichas ptyonurus Hall is foundand Cyathophyllum
~hydraulicum Simpson is quite abundant. Beneath this second
‘dolomite layer containing Cobleskill fossils, waterlime beds again
occur in which Eurypterus are found.

_ From the above conditions it would appear that while the
; Decker Ferry fauna was living in eastern New York the Euryp-
terus fauna was still to be found in the Salina sea in the western
part of the State, and that there were invasions from the eastern
“sea which at first were only temporary, but which finally caused
the retreat or destruction of the Eurypterus fauna.
