Criarke State Paleontologist Bulletin 63 PALEONTOLOGY 7 STRATIGRAPHIC AND PALEONTOLOGIC MAP OF CANANDAIGUA AND NAPLES QUADRANGLES INTRODUCTION The region covered by these maps is a classical one in the history of New York paleontology. In the days of the original survey of the old fourth district, 1836 to 1848, Prof. James Hall, the district geologist, frequently made headquarters on the beautiful shores of Canandaigua lake and both then and in later years the richly fossiliferous shale beds exposed along the lake shore and in its ravines, afforded to him inexhaustible re- . sources for collecting their organic remains. As representative of the strata embraced within the “ Hamilton group” no series of exposures in the State has been so thoroughly exploited as these. Canandaigua and its lake, 70 years ago, were easily ac- cessible and so were the numerous villages scattered through northern Ontario county, but about the latter the rock ex- posures have always been few and hard to find because of the great thickness of the drift mantle. Southern Ontario was more remote and though the township of Naples was reached by Hall it was for a brief visit only, and its splendid exposures and in- teresting faunas were left for subsequent researches, By 4 NEW YORK STATE MUSEUM Canandaigua was the writer’s home town and Naples the home of his pioneer ancestors in western New York. During the early years of youthful enthusiasm for geologic study the rocks of Canandaigua and vicinity were the subject of prolonged and careful analysis. In the days from 1870 to 1880 the entire fauna ‘was studied in such detail that the vertical range of every known species, and many before unknown, of the Hamilton Stage was established and from other formations large accre- tions to known facts were made. So productive were the in- vestigations of this period in increasing our knowledge of these faunas that in the “ Monograph of the North American Devonian Crustacea,” published at a later date as volume 7. of the Paleontology of New York nearly 200 figures were given of trilo- bites and other crustaceans collected by the writer during this time and in this region. The Portage strata of the township of Naples, as a result of careful researches begun then and continued till the present, opened up a virtually new fauna in the New York series. The study of the Portage fauna, desultory at first, began seriously only when in companionship with Mr D. Dana Luther, it was attacked with unremitting assiduity and in this companionship the exploitation of this fauna has been carried forward through- out the entire extent of this formation in the State. For 20 years no circumstances were permitted to interfere with the - yearly joint attack on this problem, and though this long standing companionship in the field has been latterly inter- | rupted by force of circumstance, Mr Luther has diligently carried on the refined stratigraphic study of the Naples rocks and their equivalents while the writer has been more specially concerned in the solution of the paleontologic and bionomic problems to which the faunas have given rise. In 18851 the writer published a geologic map of Ontario county. Up to that time the rock formations of the region had not been delineated in greater detail than given on the old IN. Y. State Geol. 4th An. Rep’t. CANANDAIGUA AND NAPLES QUADRANGLES 5 state map of 1843. This map, which was the summation of some years of observation, served a useful purpose and has been the basis of the maps herewith presented. Accompanying the map of 1885 was a brief account of the variations of the faunas ac- cording to the formations represented. Our present data enable and require us to analyze in closer detail variations in sedimen- tation sometimes accompanied and sometimes unaccompanied by variations in faunation. It was made clearly apparent by the writer’s long study of the changes in the fauna of the Hamil- ton shales and limestones that very few variations of material importance in the composition of the fauna throughout the en- tire series of these deposits were tangible and this same condi- tion has been shown to prevail in the deposits of this period wherever the sediments maintain the singularly homogeneous character shown in this section.* . We have introduced a considerable diversity of coloration on these map sheets but such refined distinctions in sedimentation are now essential to the complete understanding of bionomic con- ditions and stratigraphic changes during the period of deposi- tion of these strata. They are essential also as an aid to the correlation of the rock section here given to that in adjoining regions of the State. Many of the names may prove to serve only a local, perhaps some of them only a temporary, purpose. Certain of the divisions have however a higher value and indi- cate periods of uniform deposition over wide areas in western and central New York. An apology or excuse for the refine- ment of these stratigraphic subdivisions is not mecessary. The multiplication of local names as formation terms is one of the imperative accompaniments of progress in the interpre- tation of ancient marine conditions. *The attempt thus made many years ago to determine a basis of subdi- vision in these homogeneous sediments on the basis of the range of the fos- Sils, proved as inconsequent as similar efforts subsequently made in this series of sediments. Were one concerned to construct a doll’s philosophy from imaginary laws conceived to govern the association of species into faunules the extraordinary uniformity of faunation in these beds should afford an oppugnant problem. 6 NEW YORK STATE MUSEUM FORMATIONS The rock formations here represented as units of sedimentation may be grouped in broader divisions in the manner following: Chautauquan group Chemung beds Prattsburg [ ( West hill Ithaca beds ver tees Hatch [Rhinestree ashaqua Neo- BA scan! arait Portage beds Parrish (lentil in devonic shake ¢ Cashaqua) . Middlesex ( Standish J West river Genundewa _Genesee Tully limestone Tully ( Moscow Menteth (lentil in Hamilton beds T Moscow) | ichenor , Erian group 4 Canandaigua | Skaneateles ( Cardiff Stafford ) Genesee beds Meso- devonic Marcellus beds Marcellus Ulsterian group Onondaga beds Onondaga Oriskanian group Oriskany beds Oriskany ( Cobleskill beds Cobleskill Bertie Camillus Paleo- devonic Siluric ute forty EPP ae | Salina beds SILURIC General observations. All these formations are so deeply buried under a continuous drift mantle that their variations can be studied only at a disadvantage. We have indicated the contact lines of these as well as the lower Devonic formations as ap- pended, by slightly undulating lines traversing the region in a nearly east and west direction. It is our belief that such lines: bound the palpable outcrops over a region which before becoming enveloped in the drift was not deeply channeled and by the rigidity of its rocks was able to resist the erosion which further south has broken up the softer formations, into projections and outliers. Camillus shale The lowest formation in the rock series and northernmost on the Canandaigua sheet is that subdivision of the Salina group of formations which consists of soft gypseous shale or plaster rock, CANANDAIGUA AND NAPLES QUADRANGLES 4 dark when fresh but becoming light ashen gray on exposure. These beds are both underlain and overlain by thin light gray magnesian limestones or platten dolomites. Entire thickness 50 feet. : On account of the meagerness of the exposures throughout the northern area of the Canandaigua quadrangle the exact position of the contact line between the red or Vernon shales and the gypseous Camillus shales, which is the equivalent of the rock beds of western New York, is not apparent. The lowest rock exposures are along Mud creek below Brownsville and in the bed of Ganar- gua creek just to the north of the north line of the sheet. Here are two outcrops, one just above and the other about 25 rods below the bridge, which show a few feet of very fine hard dark bluish drab limestones characterized by needle cavities or styliolites, which mark the magnesian limestones of the gypseous deposits of the Salina group elsewhere. These layers are easily broken into small and regularly shaped blocks. Between the dolomites are thin layers of bluish clay shales. In the Goose Egg, an oval hill 1 mile south of Brownsville on the west side of Ganargua creek there occurs the most northerly outcrop of the upper gypsum or plaster bed. The exposure is a small and isolated one and is obscured by drift and disintegrated shale. Gypsum was formerly quarried here. One mile farther south the gypsum outcrops at the foot of the declivity on the west side of the Ganargua creek channel and “land plaster” has been quarried here for many years and ground in Conover’s mill near by. In consequence of the expense attending the stripping of the heavy covering of drift, 30 to 40 feet thick, the small amount of plaster produced in recent years has been mined, access to the bed being had through a horizontal tunnel at the base of the hill. The breast of the mine is 14 feet high. The gypsum is purest at the bottom. This bed is a continuation of the one from which “Onondaga land plaster ” is obtained in Onondaga county; “Cayuga plaster” in the vicinity of Union Springs, Cayuga co., and “ Vienna plaster ” along the Canandaigua outlet in the western part of the town of Phelps. It is 30 to 40 feet thick in this region and is composed 8 NEW YORK STATE MUSEUM of the hydrous sulfate principally in the impure condition and not infrequently appears crystallized as selenite and in flaky condition mixed with very soft dark bluish clayey shale. Where the gyp- sum predominates the rock has a distinctly crystalline appear- ance but where the proportion of shale is greatest the lines of sedimentation are very apparent and it has every resemblance to ordinary soft dark shale. Joints occur everywhere throughout the rock beds and through these the percolating waters have had access to the gypsum deposits and have frequently removed them, thereby causing a settling of the shale material adjacent and leaving hemispheric masses between the resultant depressions. Doubtless the present hummocky condition of the beds, not alone in this region but throughout the area of surface exposure of Camillus shales is largely due to causes connected with the change from anhydrite to the hydrous sulphate or gypsum. There are a few thin even layers of hard magnesian limestone interstratified with the gypsum and at the top of the bed there are 8 to 10 feet of soft blocky shales containing but very little gypsum. This lat- ter bed is exposed at the east end of the Lehigh Valley Railroad cut 1 mile east of the village of Victor, and also in the bed of Mud creek near the Lehigh Valley Railroad bridge and at Fredon or East Victor. The more productive development of the gypsum in- dustry in this region however is in the territory just east of the quadrangle in the town of Phelps, where for more than 70 years it has been produced on a large scale, though the production has now notably fallen away. Bertie waterlime This term, derived from Bertie township in western Ontario, is specially characterized by the abundant presence of the crusta- ceans Eurypterus, Pterygotus and Ceratiocaris. It consists chiefly, in the Canandaigua region, of hard dark impure hydraulic limestone in thick layers separated by thin seams of dark and ap- parently carbonaceous matter. The rock weathers to a light brown or buff. Thickness 40 feet. The passage from the Camillus shales into these beds now termed Bertie waterlime is a very gradual one, the loss of gypsum being CANANDAIGUA AND NAPLES QUADRANGLES 9 replaced by the addition of alumina and carbonate of magnesia, so that the succeeding stratification becomes highly dolomitic. The distinguishing mark of the division as already noted, is the presence of merostome and phyllocarid crustaceans, which at- tained at this time their culmination of development. Along the creek for 10 rods below the bridge at East Victor are from 30 to 40 feet of hard compact dolomites with dis- tinct lines of sedimentation, having a characteristic clink and conchoidal fracture. The dark blue of the rock changes rapidly on exposure to a light, dark or ashen gray. The same horizon appears in the Lehigh Valley Railroad cut 1 mile east of Victor, though the exposure here is for only about 6 feet at the bottom, just over the Camillus shales. Eastward also in the adjoining quadrangle occasional exposures are seen. Remains of the crustaceans referred to are by no means aS common here as at the well known localities to the west at Buffalo and to the east in Herkimer county but the horizon is doubtless the same, and segments, heads and appendages of these creatures are not un- common. With them is frequently found a Leperditia, probably L. alta Conrad and the brachiopods Whitfieldella laevis Vanuxem and Leptostrophia varistriata Conrad. Cobleskill shale and dolomite This is a rather obscure representative of a formation which has recently been shown by the investigations of Hartnagel to ex- tend without interruption from eastern New York to Bufialo and beyond. It is regarded as deposited soon after the close of the period of the Salina and it here consists of dark, hard shale and straticulate, impure limestone, succeeded by a thick bed of mas- sive dolomite, the top of the formation consisting of platten dolo- mites. The thickness ascribed to these beds is approximately 42 feet, of which 18 feet are assigned to the shale, 20 feet to the heavy dolomite and 4 feet to the platten dolomite on top. The section at East Victor exposes the massive beds of this horizon, immediately below the topmost layers constituting platten dolomite. In the high bluff on the east bank of the creek 10 NEW YORK STATE MUSEUM in the rear of A. B. Cooper’s residence there are beds of dolomite which, aggregating 8 feet in thickness at the base, are succeeded by 15 feet of dark bluish shale and these are overlain by 6 feet of dolomite like that below. Overlying these layers and exposed for many rods in the bed of the creek is a mass of tough argillaceous limestone 15 feet thick that bears Stromatopora quite abundantly and seems to indicate a western continuation of the well known Stromatopora bed at this horizon in Onondaga county. It is dark brownish gray when freshly broken and usually takes on a darker tinge of brown for a time owing to the exudation of a minute quantity of petroleum but finally turns to a light yellowish drab. It contains many small aggre- gations of selenite crystals, and the boulders from it by reason of their peculiarly tough character have survived glacial transpor- tation and grinding and are strung in great numbers over the contiguous territory to the south, have many small cavities and a general scraggy appearance due to the weathering out of. these crystals. A bed of shaly dolomite 4 feet thick is the highest member of the group. This appears in the west bank of the creek a short distance below a low fold 60 rods north of the New York Central Railroad bridge at Mertensia. There are several small exposures of these upper beds in this vicinity, the most extensive of which is in the section afforded in the Hog hollow or Great brook ravine on the west side of Boughton hill, where 25 feet of the top layers are well displayed. The two upper members appear $ mile east of Fredon and have been quarried on the land of A. B. Cooper and Hiram — Powell, and at the latter place there are the ruins of two limekilns where material from the Stromatopora layer was formerly burned and then hauled to Conover’s mill and ground for cement; there are several other abandoned kilns in the vicinity in which quicklime was once produced from the purer layers below. No other exposures of these beds have been observed in this western portion of Ontario county, but they are of more frequent occur- rence eastward, just beyond the line of the quadrangle and are there more freely worked and contain organic remains in greater CANANDAIGUA AND NAPLES QUADRANGLES 11 number. The fossils occurring here, besides the Stromatopora, are Leperditia alta Conrad and L. scalaris Jones, Cyathophyllum hydraulicum Simpson, Spirifer eriensis Grabau and Whitfieldella sulcecata Vanuxem. Fragments of Eurypterus also occur at this horizon. DEVONIC General observations. The division line between the great Siluric and Deyonic systems is very well marked here on account of the entire absence of the Helderbergian limestones, which, in the eastern part of the State, represent the incipient stages of Devonic deposition. There is good reason to believe that the uppermost Siluric beds which we have just considered were for a time ex- posed above water to the action of aerial decomposition and erosion before the later sediments were laid down on them. This has been found to be the case in Erie county, where the eroded upper surface of the Cobleskill dolomite is overlain by a regular deposition of the following formations. Oriskany sandstone In eastern New York this formation takes on, in certain places, the character of an arenaceous limestone but it is an interrupted deposit in its course across the State from east to west, though in places tremendously abounding in fossils. At Oriskany Falls and at Union Springs it assumes the character of a more or less friable whitish sandstone. The formation constantly thickens and thins, forming lenses, as in Cayuga county, sometimes 20 or more feet thick and then again thinning to actual disappearance. As it becomes thin it usually assumes the character of a hard com- pact quartzite composed of silicious grains cemented by a deposit of silica. Throughout western New York this thin bed frequently contains angular masses, evidently washed from the hydraulic limestone beneath and thus forms a breccia. In Ontario county the exposures of this rock are largely confined to the township of Phelps a few miles to the east of this quadrangle. From its uneven thickness and general appearance at this. place and the fact that it fails entirely within a half mile on the east and a 12 : NEW YORK STATE MUSEUM mile on the west it would indicate here as elsewhere, that it was. a deposit of a sand bar running out from the irregular coast line of the time. This deposit in the town of Phelps is the last of the len- tils which the formation assumes in western New York. It is 6 feet, 6 inches thick and consists of several distinct layers. In the upper part of the top layer there are many elongate rounded peb- bles and cobbles of black quartzite embedded in the light sandstone and the rest of the deposit is largely of coarse sand with a lumpy or slightly concretionary structure. In these outcrops the only evi- dence of fossils is the presence of a few obscure corals. On Mud creek 50 rods below the railroad bridge at Mertensia, there is an exposure of the same material but more quartzitic, containing the waterlime pebbles, the layer being 6 to 8 inches thick. In Phelps the sandstone was at one time quarried for firestone for use in the glass furnaces at Clyde. Onondaga limestone In general character this important deposit is a compact, dark bluish gray limestone frequently carrying interbedded layers of chert nodules, the limestone itself being bedded in layers from (; inches to 3 feet in thickness. It contains a large amount of carbonaceous matter, which appears on the surface of the layers and in the shale partings between them and discolors most of the strata, frequently giving them a decidedly black appearance. It is removed by gradual decomposition on exposure and the rock slowly assumes a very light bluish gray color. The chert or horn- stone is usually nearly black and slightly translucent, but some- times lighter colored and bluish. It is very unevenly distributed — in the beds in some of which it predominates and in others is entirely absent. The nodular layers in which it lies are frequently continuous for long distances and owing to their resistance to de- composing agencies, old exposures of the beds and the innumerable boulders and fragments from them strewn over thé region south of the escarpment formed by this formation, have a peculiarly ragged and scraggy appearance. At some of the outcrops one or more of the layers are shaly but only a small proportion of the formation is of this character and all of the remainder, wherever CANANDAIGUA AND NAPLES QUADRANGLES 13 the amount of chert is not too large, is compact and durable and exceedingly valuable as building stone and for the production of quicklime. If the chert is entirely absent the limestone is easily quarried and makes very handsome dark gray cut stone building material, and the cherty masses have been extensively worked for bridge abutments, canal locks, retaining walls and kindred pur- poses. This formation covers a belt 1 to 3 miles wide across the towns of Mendon, Victor and Farmington and some exposures of the uppermost beds occur also in Canandaigua. The more striking outcrops of the rock and those which have long been most avail- able for exploitation are in the region just to the east, specially in the towns of Manchester and Phelps. In a general way it may be stated that at the base of the formation there are from 3 to 5 feet of limestone, very rich in corals and without any chert. The rest of the formation which attains a total thickness of about 120 feet has both chert and shaly layers scattered through the limestones at irregular intervals. In Farmington the lower beds crop out on the north side of the road leading from Manchester to Victor and have been extensively quarried, the stone used in the construction of the Erie canal locks at Macedon having been obtained from this locality. In the bed of Mud creek the base of the formation appears about 60 rods below the railroad bridge at Mertensia, in a low anticline, the axis of which crosses the stream diagonally. Here it rests on the Oriskany sandstone and the lower 5 feet are free of chert and are crowded with corals, the stratum being identical in character and appearance with the basal layer farther east. These layers are capped by a series of chert-bearing beds, together aggregating 5 feet in thickness. Above the bridge there is an extensive picturesque cascade and an exposure of 40 to 50 feet of the middle and upper beds, the outcrops extending though not continuously, 100 rods south of the cascade. The rock at this place has been worked for construction stone. In the section along Great brook or Hog hollow at Victor the lower layers appear overlying the Oriskany and at this point tbe 14 NEW YORK STATE MUSEUM rock was formerly quarried both for building stone and for burn- ing. In the ledges of the creek above the quarry are some of the higher cherty layers. For the most part however the formation is buried under the drift and from this point to the western limit of the sheet no other outcrop has been found. The higher layers of the limestone, lying with glaciated surface beneath the soil cap, are seen in the old Giddings quarry, now known as the Bacon quarry just to the east of the edge of the map. In general it may be said that this formation forms the most important repository of valuable building material within the region covered by the map, and furthermore in the harder chert layers is a convenient and inexhaustible source of road material not inferior in quality to the field stone that has been generally utilized in the county in recently constructed roads. Marcellus shale The term Marcellus shale has been generally applied in New York geology to a black and dark blue shale formation lying im- mediately on the Onondaga limestone. The lower boundary of the formation is always perfectly clear but not so with the upper, » for the mass passes gradually into the lighter gray shales of the Hamilton group above. At Marcellus village, Onondaga co., from which place the name is derived, only the lower layers of this black shale are well exposed and our observations both in that region and thence westward indicate the desirability of re- stricting the term Marcellus to these lower shales, which are typically exemplified in the original locality but are _ better delimited upward in Ontario county by the presence here of a limestone cap—the Staiford limestone. Using the term in this restricted sense the Onondaga limestone is overlain’ everywhere by black slaty shale with a few thin calcareous layers and rows of spheric calcareous concretions. The shales are highly im- pervious and argillaceous and withstand exposure so well that their outcrops are usually vertical or overhanging cliffs in a CANANDAIGUA AND NAPLES QUADRANGLES 15 region where there has been but little deep stream-cutting. Owing to their rigidity they are highly jointed and rhomboidal, triangular and diamond-shaped slabs being characteristic of all surface exposures. It is difficult to estimate the thickness of this bed but it appears, from comparison of outcrops here with the total thickness afforded by the Livonia salt shaft section where it was 48 feet with a slight tendency to increase eastward, to be about 50 feet. The actual contact of these beds with the underly- ing Onondaga limestone has not been observed, but the lowest out- crop of the formation on this quadrangle appears on the west side of the fill on the New York Central Railroad, just north of the cut near Padelford. The higher beds are well exposed in this same.cut where they are densely black shales with some thin limestone layers. The same beds appear along Mud creek about a mile south of Mertensia. The distinctive character of this shale as an initial part of the beds which have heretofore generally been assigned to the Mar- cellus stage, is its uniformly bituminous nature and consequent dark color and its very small proportion of lime content except in the thin calcareous beds themselves. Stafford limestone The group of strata which have customarily been incorporated within the general term Marcellus shale embraced an interesting limestone layer, the presence of which was early noted by Pro- fessor Hall and which was termed by the writer some years ago Stafford limestone, on account of its high development at Stafford in Genesee county. This is a dark chocolate and somewhat nodu- lar limestone, very hard when fresh but breaking easily into angular fragments on exposure. We have shown in various pub- lications that this formation extends eastward with a diminish- ing thickness and we know that its last surface appearance is along Flint creek in the southwestern part of the town of Phelps, Ontario co. Though not exposed to the eastward it is evident that the formation in slight thickness (it has a thickness of about 8 inches in Phelps) occurs as a thinning wedge through this area, 16 NEW YORK STATE MUSEUM for the very characteristic blocks of this rock are quite freely scattered south of the line of outcrop and specially in the east bank of Mud creek. Two miles south of Mertensia the blocks are so common and in such a condition as to indicate very slight removal from place. Cardiff shale The upper beds, heretofore generally included in the old term Marcellus and termed by Vanuxem the “ Upper shales of Marcellus” are finely shown in and about the village of Cardiff, Onondaga co. As we have restricted the former term, it seems best to adopt for the succeeding layers a name derived from these excellent exposures near the typical region, as in Ontario county they are nowhere seen to so good advantage. The Stafford limestone is overlain by a series of dark calcare- ous and black slaty shales with thin layers of fossiliferous limestone. Both limestone and shales weather to a light ashen gray on long exposure. So far as the fossil contents are con- cerned they are not essentially unlike those of the darker shales below but the gray aspect of the beds and their much higher calcareous content indicate a distinctive difference, which is | readily marked throughout this region. Outcrops of these lay- ers are again very few. The best of them is in the bed and sides of Mud creek at its confluence with Shaffer creek in the north- eastern corner of the town of East Bloomfield. They are also exposed in the upper part of the railroad cut section just south of Padelford station. Directly over the line of the quadrangle to the east is an exposure on the east bank of the Canandaigua outlet below Chapinville, and here some of the harder layers were at one time quarried for flagstone and used in the village of Canandaigua but they proved to check very rapidly under exposure and wear. Fora quarter of a mile this exposure is continued in the bank of the outlet. At no exposure is the entire thickness of this bed revealed. The heaviest mass of material shown at any one place is in the section on Flint creek just south of Phelps, Ontario co., where there lie on top of the Stafford limestone about 50 feet of these shales, the cal- CANANDAIGUA AND NAPLES QUADRANGLES 17 careous material increasing toward the top though the dark shales predominate throughout. The gradual increment of lime content makes the passage from this bed into that following essentially imperceptible, but there are accompanying notable distinctions in the composition of the fauna.’ Taking into ac- count a proper allowance for dip it is estimated that the thick- ness of the Cardiff shales is here about 100 feet. Skaneateles shale This term was applied by Vanuxem to the beds immediately overlying the upper Marcellus, and exposed on both sides of Skaneateles lake at the north end. They are evidently con- tinuous into the Canandaigua area without essential contrac- tion or change and hence the early term is now employed for them rather than the designation Shaffer shale incidentally used in a recent tabulation of these formations. With the in- crease in calcareous matter ihe shales become hard, blue black, in places quite black, passing into light and softer beds above with layers of soft impure limestone. For a thickness of 125 feet this shale bed keeps its distinctive characters across the Can- andaigua sheet though the distinction is based on comparatively few exposures. These deposits are exposed in the bed of Mud creek south of the highway bridge near the junction of Shaffer creek, 4 mile north of Wheeler and also along Shaffer creek at 4 to 2 mile south of Wheeler. A slight exposure of the black shales is also shown in a small drainage section just below the Robertson quarry adjoining the New York Central Railroad on Fort hill in the eastern part of the village of Canandaigua. They are shown in nearly full strength in Miles gully in the town of Hopewell, just east of the east line of the quadrangle. Canandaigua shale Including the Centerfield limestone at the base Two terms which have become ingrained by long usage in the nomenclature are the Hamilton group and the Ludlowville shales. ' The former, introduced by Vanuxem in 1840, was at no time em- 18 NEW YORK STATE MUSEUM ployed by the original state geologists in any other form and it is evident that the significance here of the term group is its refer- ence to the variability of the strata in the typical Madison county sections where they are sandstones, arenaceous and argillaceous shales, not a composition of defined lithologic units. In other words the term is used with the same breadth of meaning as other unit terms of the series and not as the word was subsequently em- ployed in the final reports of the geologists nor in the widely dif- ferent sense made use of by Dana and generally current. The division was clearly defined and its place in the series is precisely that ascribed to the Ludlowville shales in the Cayuga lake section as was defined by Hall in 1839. Ludlowville was not altogether well chosen as exemplifying the latter division, for the Tully lime- stone is present in the village and the Moscow shales beneath; one must go afield to find the true Ludlowville strata, but it is evi- dent that Professor Hall’s conviction at that early day that these were the representatives of the Ludlow shales of Eng- land, influenced his choice of name. We would reject neither name in favor of the other. Each expresses essentially the same interval but a differing series of sediments and some marked distinction in fauna. Each will be found to have a definite meridional value. Hence further west and in the area here under consideration we find still other differences ex- pressed in this interval both lithologic and faunal and are constrained to express these by the terms employed above. The Canandaigua shale is constituted of soft, dark bluish and gray calcareous Shales with impure limestone beds at the bottom, and irregularly nodular calcareous beds abounding in corals toward the middle of the formation. This is a highly fossiliferous mass and its distinction from the beds beneath lies not alone in the nature of its lithologic character, but essentially in the abrupt manifestation of the highly profuse and typical Hamilton fauna. The Skaneateles and Cardiff shales have been regarded as a_ kind of transition deposit from the typical bituminous Marcellus shales indicating the gradual approach and encroachment of normal Hamilton CANANDAIGUA AND NAPLES QUADRANGLES 19 conditions together with the advance of the Hamilton fauna. - The estimated thickness of the Canandaigua shale is about 125 feet. It is excellently exposed along Shaffer creek immediately south of the exposure referred to above and about a mile north of the village of Centerfield. At this locality the lower calcareous layers and the shale overlain by the coral beds are admirably exposed and have been a most prolific source of fine fossils. These beds also appear within the village of Canandaigua, there being exposures of the impure calcareous beds on east Gibson street at the now abandoned Maggs quarry and also in the more recently opened quarry on the Robertson property south of the Chapinville road. Here the beds, when fresh, are a fairly compact limestone but their schistose character soon checks them on exposure, and they have never proved a satisfactory construction stone. They are however enormously prolific in corals and represent the coral reef better exposed on Shaffer creek. It is probable that beneath them lie the shaly beds, but the limestones which Jie near the bottom on Shaffer creek and which are of more compact char- acter, though somewhat more argillaceous in composition, may prove to be absent here. Below the Robertson quarry, to the New York Central Railroad tracks, is a small drainage way which gives indications of the underlying beds down to the blue black Skaneateles shale. The exposure however is not sufficiently clear to demonstrate the presence of the limestone beds referred to. If they are here they would serve as a more substantial building stone for rough purposes such as foundations and cellar walls, than the stone above, that is now or has been worked for this purpose. These lower limestones, which are specially character- ized by their fossil contents and have produced some species which have not been found elsewhere, have been designated in a sub- sidiary sense as the Centerfield limestone. The upper beds of the Canandaigua shale outcrop on the east shore of Canandaigua lake at Cottage City and in the ravine of Gage’s creek and Deep run. On the west side of the lake the shale beds are well shown in the cliffs between Tichenor and Men- 20 NEW YORK STATE MUSEUM teth points below the Tichenor limestone, and from Tichenor point northward there are several small outcrops along the side hill as far as Hope point and over the region to the west- ward; lying just at the lower declivity of the rise of land the rock appears where the drift mantle is thin. This mass of sediments is probably equivalent in part to the Ludlowville shales of Hall, but at Ludlowville a limestone called by Hall the Encrinal limestone was taken as a line of division between the shale masses, the upper being called the Moscow and the lower the Ludlowville. It is yet to be determined whether that Encrinal limestone is continuous with the Encrinal or Tichenor limestone of the section under consideration and for the present we can not employ here the name Ludlowville with entire security. Hence the term Canandaigua shale is employed on behalf of more accurate, though perhaps provisional expression. Tichenor limestone This name is applied to a compact layer of hard bluish gray often crinoidal limestone which has a thickness of about 1 foot. It is separately designated for the reason that it is a continuous formation across this area and well to the east and west beyond it. It contains some of the characteristic fossils of the rock but they are not specially abundant and are frequently replaced by depo- sitions of strontianite. This rock has been commonly known as the Encrinal limestone, a name applied to it by Hall as long ago as 1839 and has been used by many writers in application to limestone layers lying at actually distinct horizons in these rocks, specially from the meridian here under consideration to Lake Erie. On comparison of this section with that on Cayuga lake where the Ludlowville shales were originally defined and the typi- cal exposure of the Encrinal limestone was located, it was found that there is no concurrence in the horizons indicated there and here by the same term. In view of the various limestone strata that have been referred to under this name and its extraordinarily -frequent employment throughout all geologic formations with a great variety of stratigraphic meanings, it is best to abandon the CANANDAIGUA AND NAPLES QUADRANGLES 21 term altogether. At Tichenor point the limestone is exposed along the roadside at the opening of the ravine and it reappears on the shore of the lake just south of Tichenor point where it forms a low but well marked anticline cut off at one end by a slight displacement. Here it dips under the water and reappears at the north side of Menteth point forming a broad platform at the water level. | These are the best outcrops of the formation known in Ontario county and the rock also appears slightly in the lower part of the Miles gully in-Hopewell and on Flint creek south of Castle- ton. A limestone of similar character is exposed in the bed of Beebe brook, West Bloomfield, but it is not altogether certain that it belongs to this horizon. Moscow shale The Tichenor limestone is overlain by a mass of mostly soft, light bluish gray calcareous shales, becoming darker toward the upper part. Thin layers of limestone usually extending but a few rods and irregular calcareous lenses largely composed of fossils are of frequent occurrence. At the base of the mass lying im- mediately on the Tichenor limestone the shale is very compact and highly calcareous and breaks out in irregular slabs. This pertion of the deposit is very persistent over a wide area and is characterized by the abundance of crinoids which it contains in the most admirable preservation. Indeed this is the horizon which has furnished all the superior crinoid material from these rocks in this part of the State. It is this layer, which with the Tichenor limestone has in previous reports, specially the descrip- tion of the geology of Ontario county published by the writer, been designated as the Encrinal band. An exposure of this layer on ihe farm of Mr Sisson, not far from the village of Muttonville, now Vincent, in the northern part of the town of Bristol, afforded to the collectors of the State Museum in 1860, C. A. White and C. Van Deloo, an immense amount of fine material, constituting the best preserved and most complete series of crinoid calyxes ever obtained from the rocks of this State. This exposure is 22 NEW YORK STATE MUSEUM no longer accessible and appears to have been overgrown by vege- tation with the drying up of the brook. Seventy-five feet above the Tichenor limestone is another limestone layer lying in the midst of this shale mass. This is here designated as the Menteth limestone, and is worthy of special remark for sey- eral reasons. It is a well defined bench mark in these Moscow shales entirely across the map. As a rock it is a compact layer about a foot in thickness and usually very pure but in places it proves to be quite argillaceous and nodular. It isa notable re- pository of the fossils of the fauna and these are very frequently replaced by silica with a degree of delicacy and perfection seldom equaled; perhaps not elsewhere in the paleozoic rocks of the State nor in rocks of ancient date from any locality known to the writer is this replacement so satisfactory to the student of the biologic problems of paleontology. The etching of the purer part of this layer has afforded a most beautiful series of the species of the fauna and as these are retained not alone in adult condition but from the earliest shell-bearing stage on, the ma- terial has already been the subject-matter of several important treatises on phylogeny, ontogeny and the systematics of different groups of organisms. We may refer to the papers of Beecher on the trilobites and on certain of the corals, to Grabau’s investiga- tion of the corals, to the writer’s publications on some of the brachiopods, etc. An indication of the delicacy of these replace- ments is afforded by some of the shells of the brachiopod Produc- tella in which the hairlike spines on the body of the shell projecting for a length greater than the diameter of the shell itself, are preserved without defect. This Menteth limestone forms the first falls in the ravine at Tichenor point and also in that at Menteth point. It and the shales beneath are well exposed in these places and the shales themselves specially along the shore of the lake between the two points. On the opposite or east side of the lake both shales and limestone are found in Gage creek and Deep run, and again on the east side from Menteth point southward to Foster point. Farther north is an exposure of the limestone and some of the underlying shales at Hope point ravine. CANANDAIGUA AND NAPLES QUADRANGLES 23 The upper part of the Moscow shales is expesed on the east side of the lake in the Gage creek ravine where, about 50 feet above the Menteth limestone, a series of nodular layers of limestone 2 feet thick form a low cascade. Also in the ravines of Bennett’s landing, Gooding landing, Long point and along the lake road and shere to the Gorham-Middlesex town line. The same series is displayed on the west side of the lake from 4 mile south of Black point northward to Foster point, and in the upper parts of the Menteth, Tichenor and Hope point gullies. They are shown in the bed of Shaffer creek + mile north of the Gooding schoolhouse near the western boundary of Canandaigua township and also in the Bristol valley in several small ravines on the east side be- tween South Bloomfield and Vincent, and in the lower part of the ravine on the east side of Baptist hill. Tully limestone Ontario county includes the westernmost and final appearance of this important, though relatively thin, rock formation. In the towns of Geneva-and Seneca to the east and also in Gorham, except close on the shore of the lake, this limestone appears with constantly diminishing thickness, and its last appearance is in Gage creek about 40 rods east of the eastern boundary of the map. Here it is a bed of dark bluish gray, hard, brittle limestone and at its last exposure attains a thickness of 2 feet and 8 inches. Doubt- less the stratum extends a mile or more beyond this point to the southwest, as some loose blocks 8 inches thick, apparently but slightly displaced, lie in the bottom of the small gully at the side of the road leading eastward up the hill from Bennett’s landing. Eastward of this region and throughout central New York as far as Chenango county the Tully limestone is prominently developed and attains at its maximum a thickness of from 20 to 30 feet. On the Canandaigua sheet at all other exposures except those men- tioned, the Moscow shales beneath and the Gorham shales above are in contact or separated by lenticular discontinuous layers of iron pyrites from 10 to 50 feet on the edge and 1 to 4 inches in thickness, the material of which is very hard and in damp places is 24 NEW YORK STATE MUSBUM not affected by exposure but in cliff faces is usually disintegrated. This singular deposit is exposed in the ravines on the east side of the lake from Gooding landing southward to Fishers and in the shore cliffs to the Gorham-Middlesex boundary. On the west side from just south of Black point along the shore and northward in ravines at Grange landing, Victoria glen, Foster point and Men- teth point; also following the Moscow shales in the localities in the Bristol valley already cited. This layer of iron pyrites is con- tinuous from this region westward to Lake Erie and indicates with striking persistence the horizon of the Tully limestone as a plane of division between the Hamilton group of formations be- neath and the Genesee above. The Tully limestone itself as exposed in Ontario county locali- ties to the east is a very dark bluish eray rock weathering at first to lighter shades of blue and after long exposure to an ashen gray. It is in two or three layers that are very hard and apparently compact when freshly quarried. On exposure the rock checks along irregular seams and develops a tendency to split into irregu- Jar angular fragments an inch or two in diameter. It has been used for construction stone and at one time was burned for quick- lime near the village of Gorham. On Fish creek 14 miles directly east of Reed Corners, where the highway crosses a small brook, is an exposure showing 4 feet and 2 inches of the limestone, and this exposure seems to have been noted in the report by Professor Hall on the geology of this region in 1843, then regarded as the most westerly appearance of the rock. A more extensive exposure is shown however on lot 58, 1 mile southwest of Reed Corners where the north and south “ middle road ” crosses a small brook flowing west into Canandaigua lake from a ravine about 40 feet deep and 50 rods long above the highway. Here the limestone forms a floor in the ravine for 2 rods and produces a cascade 8 feet high. The exposure continues for 10 to 12 rods on both sides of the gully and at the cascade the total thickness is 5 feet, 10 inches. Still another outcrop is found 2 miles south of the latter on the lake road from Rushville to Canandaigua near the residence of Mr Merritt Cole. This is the outcrop referred to as being near the ak CANANDAIGUA AND NAPLES QUADRANGLES 25 eastern limit of this map and here the exposure shows not only the black Gorham shales above but the soft Moscow shales beneath. It is separated by a thin shaly seam into two layers, and in the lower layer iron pyrites is highly abundant in nodules, probably representing the commencement of the pyrites layer, which from here westward is the sole representative of this formation. The place of the Tully where the limestone is wanting and the pyrite layer not clearly apparent is always well defined by the sharp line of contrast between the gray Moscow shales beneath and the overlying black Gorham shales. The Tully limestone, as has been recognized since the observa- tions by Conrad in 1886-37, is distinguished by the presence ~ of the species Rhynchonella or Hypothyris cuboides and the equivalency of this geologic horizon with the Cuboides zone of Europe has been a fact of general recognition for more than half a century. This fossil is very abundant in the outcrops in Ontario county but the rest of the fauna is essentially that of the underlying beds of the Hamilton group, specially the Moscow shale. We shall presently note in more detail that the fossils contained in the pyrite layer have all been singularly dwarfed by the unfavorable conditions of growth and are regarded as repre- senting stages of arrested development of Hamilton species, the characteristic Hypothyris cuboides not having been found therein. — : Genesee shale This term was originally applied by Hall to a division on the Genesee river section consisting of very dark bituminous beds at the base becoming lighter colored and more sandy upward. The highly bituminous beds are distinctly defined by their character and their definition at the top by the Genundewa limestone. It was clearly this excessively black mass of shale that it was in- tended to distinguish by the name Genesee and as it is now im- portant to refine the subdivision of this series of sediments for more exact correlation, it is here proposed to restrict the term Gen- esee to this lower member only. Directly over the Tully limestone, or its horizon when absent, lies a mass of densely black bituminous shale becoming very 26 NEW YORK STATE MUSEUM fissile on exposure and splitting into large flat plates. Owing to their rigidity these shales are traversed by parallel series of joints intersecting each other at different angles and producing in cliff exposures striking masonry effects like buttresses and bastions and on the surface of horizontal exposure equally strik- ing tesselations, triangles, rhomboids, diamonds and kindred forms. Intermingled with these beds are well defined hori- zontal rows of calcareous concretions. Occasionally a thin plate of limestone is shown. The beds also contain iron pyrites in nodules and nodular layers. This mass at once recognized by its structural characters as indicated has a thickness of 95 feet and is terminated by the Styliola limestone or as here designated, the Genundewa limestone. All these shales are extremely sparse in fossils, more highly bituminous beds showing remains of plants and Conodont teeth, and where the beds become a little bluer and slightly calcareous are Lingulas and Orbiculoideas with Ptero- chaenia fragilis. These strata are finely exposed all through the upper parts of the ravines on the east side of the lake from Gooding landing - southward to Fishers and in the shore cliffs to Genundewa which lies at the base of Bare hill as it is termed on the map; on the opposite side of the lake in the shore cliffs from Hicks point north- ward to Black point, and in the lower part of the ravine at Seneca point and the upper parts of ravines back of Grange landing, Victoria glen and Foster point, and throughout most of the rock section in the Menteth ravine back of the village of Cheshire. In the Bristol valley the upper parts of all the ravines heretofore mentioned from South Bloomfield to Vincent and also at Baptist hill show these rocks. They appear as far north as the upper reaches of Shaffer creek near the western town line of Canan- daigua, and west to Baptist hill along the valley of Beebe brook. Genundewa limestone | A dark gray limestone in layers of from 2 to 10 inches in thick- ness separated by dark or black shale. Some of the layers are even and flaggy, others are concretionary and nodular. Where purest the limestone is almost wholly composed of the shells of CANANDAIGUA AND NAPLES QUADRANGLES 27 Styliola (Styliolina) fissurella and from that fact has taken the name of Styliola limestone, by which it has been generally known. The horizon is well marked and divides the mass of Genesee deposits into nearly equal parts in this section. It is a persistent stratum and has been traced to the east as far as Seneca lake and westward to Lake Erie. The character of this rock is well displayed at the typical outcrop on the shore of the lake at the foot of Bare hill or, as it should be termed, Genundewa. Here it consists of three layers of rather soft and slightly shaly limestone, the rock being impregnated throughout with myriads of the shells of Styliola; is highly bituminous and hence very dark when fresh. The lowest of these layers is 8 inches thick, the second, 7 feet higher, is 6 inches and the third, 6 feet above, © 10 inches, making the total thickness of the entire band including the intervening shales, 15 feet. These layers increase in thick- ness westward, become less shaly and more nodular, and are event- ually consolidated. On account of the durability of this rock it is a permanent feature in all exposures of this horizon and as its peculiar character makes them easily recognizable the Genundewa limestone is important as a stratigraphic bench mark. The rock is of singular interest from a paleontologic point of view as will be noticed hereafter. Its calcareous nature being largely due to fossil remains it has afforded a fauna of consider- able scope. We find the best exposures of this limestone in the county in the cliffs north of Hicks point and in the Seneca point ravine where it produces the first cascade, also in the Victoria glen and Foster ravine and on the south branch of the Menteth brook where it produced the high cascade ~ mile south of Cheshire. The point last named is the spot at which the rock was originally located by the writer, though specimens from it had been generally known to students for some time before. It is also displayed admirably at the mouth of the Wilder ravine at Bristol Center and in the ravine on the opposite side of the Bristol valley. In Mill creek or Mill gull in the town of Rich- mond there is an exposure several rods long in the bed of the stream and the limestones are well developed and highly fossili- ferous. 28 NEW YORK STATE MUSEUM West River shale Fine, blue black or dark gray shales with thin bands of black slaty shale at intervals of 2 to 6 feet. Spheric or oblong con- cretions are common, occurring Singly or in rows. A few thin, sandy flags occur in the upper part of the beds. These shales are contrasted with the Genesee shale below by their lighter shade and their much less bituminous character, for the most part being highly fissile and breaking out into thin, sharp but small laminae. The lighter parts of the mass are easily eroded, being © tenuous and clayey and the streams that flow down the hillside have cut numberless narrow, deep gullies in them, the sides of which are steep slopes of slippery shale. The concretions in the Shale are frequently highly characteristic and are the source of most of the very abundant specimens of these bodies which are found scattered over the region and have been collected by the residents on account of their curious forms, suggestive of turtles, human skulls, hats and various other rounded objects. They not infrequently carry fossils in much better condition than found elsewhere in the beds, and these fossils of the concretions are more in accord with the singular fauna of the Genundewa limestone than are those of the shales. In the shales organic re- mains are of more frequent occurrence than in the Genesee shales beneath but they are seldom abundant. This rock is shown in the lower part of all the ravines in the Middlesex valley north of the Goodrich gully. There is also a small outcrop by the roadside half a mile north of Rushville and along several small brooks in the southwest part of the town of Gorham. In the Snyder gully just above Woodville at the head of Canandaigua lake they are well shown, and also in the lake cliff at Woodville where their peculiar blocky structure, ‘due to numerous joints, is finely displayed. The deeper parts of the ravines at Coye, Granger, Lapham, Cook and Hicks points and all of the other gullies between the head of the lake and Seneca point are in these shales; also the Seneca point ravine above the first cascade and the upper part of Victoria glen and Foster gully. Northerly exposures are also shown in CANANDAIGUA AND NAPLES QUADRANGLES ' 29 the bed of the creek at Cheshire. They enter largely into the composition of the lake wall on the east side from Genundewa south to Woodville, but here the rock exposures are extensively overgrown. In the Bristol valley they are displayed in the large ravine of Wilder creek and from there southward in the Reed and Packard ravines and in several other smaller gullies on both sides of the valley. The south branch of Beebe brook in the northwest corner of Bristol township flows through a small gully cut in the shales of this horizon, and in the town of Rich- mond the rocks are exposed in the cliffs of Mill gull. Here, a short distance above the outcrop of Genundewa. limestone, the cliff walls are handsomely banded by alternating layers of black beds recurring among the blue gray layers. Standish flags and shales Thin, uneven, bluish gray flags and olive shales. This is a thin bed of rocks probably not exceeding 15 feet in thickness, but it has seemed entitled to distinctive designation because it marks a transition from the argillaceous shales of the West River beds into the arenaceous sedimentation, characterizing for the most part, the mass of the Portage strata. The beds were originally designated by the writer “ transition shales ” in recognition of the fact referred to. It is not a persistent deposit for any great distance from the region immediately under con- sideration. The mass, thinning out toward the west, disappears altogether in the Genesee valley and by its absence the over- lying bed of black shales (Middlesex shales) is brought directly on the West River beds. The beds show some difference from those below in faunal content. Exposures are seen in the locali- ties already mentioned where the outcrops are sufficiently con- tinuous, specially in the Middlesex valley in the ravine 50 rods north of the Lee schoolhouse and in other ravines at the north to Middlesex Center, and on the west side of the valley in the Goodrich gully running up into South hill and ravines to the north; in the Canandaigua lake valley, in the Standish gully and the ravines from Woodville to Cook point, and in the upper 30 NEW YORK STATR’ MUSEUM reaches of the ravines farther north; in Bristol hollow near the lower part of the Randall gully and also in the Reed and Wilder ravines. Middlesex black shale It has been customary to regard the Genesee group of strata as closing with the foregoing and to place the Middlesex shale at the base of the Portage series. This Middlesex shale is a very black, somewhat slaty shale with thin arenaceous gray flags in the upper and lower portions. When Professor Hall introduced the desig- nation Genesee shale for the black shales in the Genesee river sec- tion, he expressed the opinion that eventually it might be found advisable to include them within the limits of the Portage forma- tion. We have shown that on paleontologic grounds this is neces- sary, and it is clearly apparent that the geologic character of the deposit shows that the Genesee black shales are but an intro- ductory phase of Portage sedimentation repeated in the Middle- sex and Rhinestreet bands. The Middlesex shale attains a thick- ness of 35 feet where fully exposed in the Middlesex valley and decreases westward to 25 feet in the valley of Honeoye lake, just beyond the west line of these maps. Fossils are of great rarity. Plant remains occur in the shales, and these have also afforded a single specimen of the goniatite Sandbergeroceras syngonum. Occasionally a char- acteristic lamellibranch of the Cashaqua shales above appears in the gray flags of the lower beds. This mass of black shale is con- tinuous westward to Lake Erie but it decreases gradually in thick- ness till on the Lake Erie shore at the mouth of Pike creek there are but about 6 feet of it remaining. The rock is well exposed in the Middlesex valley in most of the ravines between the Lee schoolhouse and the village of Middlesex. _ It is seen on the road- side on the east side of the swamp at the head of the lake and in the Canandaigua lake valley by the road 13} miles south of Woodville, also on the road leading west at the head of the lake and in the Standish, Coye, Granger, Lapham, Cook, Hicks point and Seneca point ravines, by the side of the Academy road 1 mile south of Cheshire. In the Bristol valley it may be observed in CANANDAIGUA AND NAPLES QUADRANGLES 31 all the ravines already mentioned and in the Hamilton gully, Mill gull and Jason gull in the valley of Honeoye lake. Cashaqua shale This name was introduced by Professor Hall for the characteris- tic olive gray shales with occasional flags and sandstone as devel- oped along the Cashaqua creek, a confluent of the Genesee river. As these beds are continuous from that point eastward to the area under consideration the term is completely applicable here. In this area this mass of shales attains a thickness of about 230 feet, and is mostly bluish gray and olive shale with a few thin dark layers and with two bands of thin sandstone and numerous flags in the lower part. Calcareous concretions and discontinuous con- cretionary layers occur in the upper part. As a whole the deposit in Ontario county is more arenaceous and less calcareous. than that in the Genesee river section. In the lower 75 feet the more sandy beds are rarely fossiliferous, showing occasional lignites and frequently the object termed Fucoides graphicus. At about the middle of the series the shales become softer, and here the characteristic fauna of these Portage rocks is typically devel- oped with numerous goniatites, Bactrites and lamellibranchs of the genera Buchiola, Lunulicardium, Ontaria etc. The character of this fauna is referred to in a subsequent paragraph. Above these more highly fossiliferous beds is a band of compact sand- stone and hard shales which is succeeded by 57 feet of soft, blue and olive clay shales, characterized by nodular structure due to irregular concretions of lime carbonate of small size. Six feet above the sandstone is a singular concretionary limestone which is continuous in character, attains a thickness of about 6 inches and is a mass of red and greenish kramenzel abounding in gonia- tites and Orthoceras. This layer is so distinctive, both on account of its color, its contents and its composition that it is here desig- nated as the Parrish limestone. It appears first on the western boundary of the Naples valley and is continuous from there eastward as far as Big stream and Glen Eldredge on Seneca lake. Its place in 357 NEW YORK STATE MUSEUM the succession is apparently indicated in the western part of the quadrangle by a row of fossiliferous spheric concretions which appear in the Bristol and Honeoye valleys. The Cashaqua shale, flags and calcareous beds constitute the principal situs of the fauna of the rocks and their exposures can be studied to best advantage in the admirable outcrops on the east side of the Naples valley, specially in the great Parrish gully at Varrish, the Caulkins gully and other small ravines cutting back into Hatch hill. The rocks are also shown in the face of Hatch hill behind the fair-ground and southward. The west side of this valley also affords some admirable exposures as in the Lincoln gully and thence northward on the western slope of Canandaigua lake in scores of ravines and gullies and along the dugway roads as far north as Cheshire. They are also displayed in the upper parts of all the gullies in Bristol] Center southward to nearly the end of the valley and along Egypt brook and its various branches in South Bristol and also in the upper part of Jason gull. In the Honeoye lake valley the decreasing proportion of the arenaceous layers toward the west is noticeable, the shales becoming more calcareous and concretionary. The Briggs and Hamilton gullies near the west line of the map in the Honeoye valley afford particularly favorable outcrops for study. Nearly all the Cashaqua shales are to be seen under specially favorable conditions along the Whetstone brook west of Honeoye village from the Livonia road to the falls at the Devil’s Bedroom. East- ward of Naples they are found in Italy hollow at the mouth of the ravine which crosses the road at the Big Tree schoolhouse. In the Middlesex valley they are well seen in the Clark and Mower > gullies and also in the Lee, Goodrich and other small ravines farther north toward Middlesex Center. In fact in these high lands of the southern part of the map wherever the relatively thin drift mantle has been transected by streams these beds are brought to light. Rhinestreet black shale Black slaty shale with a small proportion of blue shale and oc- casionally thin but lenticular sandstones. Thickness 18 feet on the eastern boundary of the quadrangle increasing to 30 feet at CANANDAIGUA AND NAPLES QUADRANGLES 33 the western. This tendency to increase westward is manifested beyond the area of the map, for we find the bed to be continuous from here to Lake Erie, where its thickness is more than 200 feet. It may be traced eastward to Seneca lake, where its thickness is but 1 foot. The rock is essentially devoid of organic remains with the excep- tion of fragments of plants, specimens of Spathiocaris, teeth of Conodonts and a few small Lingulas. These rocks are to be seen in Italy hollow in the ravine already referred to near the Big Tree schoolhouse, in the Naples valley at the foot of Hatch hill near the salt well, on both sides of the Naples and Middlesex val- leys to Middlesex Center,and on the north side of Genundewa. The formation takes its name from the exposure on the road running from Naples to Seaman hill, on the west side, which is known locally as Rhinestreet and along which there are constant expo- sures of this formation. They may be seen also in the upper part of all the large ravines on the west side of Canandaigua lake to the iron bridge over the Foster gully, 2 miles south of Cheshire ; in the Bristol valley in the ravines on both sides as far north as Bristol Center and about 4 mile north of Boswells Corners; in the Honeoye valley in all the ravines between the Hancock farm and the foot of the lake. Hatch shale and flags Blue and olive shales with frequent thin layers of black shale and thin sandstones. The sandstones become more frequent and thicker in the upper part of the formation; the lower layers carry very symmetric calcareous concretions from 2 inches to 2 feet in diameter. This mass immediately overlying the Rhine- street black shales, or the second black band of some of our reports, attains a thickness ‘of 290 feet and its resistant char- acter, due to the presence of many layers of hard sand- stone and flags, is the fundamental cause of the highlands on the Naples quadrangle. These beds are equivalent in part to the Gardeau beds of Hall in the Genesee valley section, but there are reasons for not applying the latter term in the Naples meridian as it can not be employed with exactitude. ‘“ 34 NEW YORK STATE MUSEUM These upper beds occasionally carry the fossils of the Casha- qua shale, but in no place are they of frequent occurrence except occasionally in replaced condition in the calcareous concretions. Toward the more sandy middle and upper portions of the series plant remains are not infrequent and from these beds has been obtained a Lepidodendron of commanding proportions, taken from a horizon at the mouth of Grimes gully, Naples, 74 feet above the Rhinestreet shales. The specimen when taken out measured 15 feet in length from the root upward. ; Exposures of these beds are found throughout the Naples valley and constitute the entire lower part of Hatch hill, in the Tannery gully just south of Naples and in the Grimes gully on the west side, also in the higher parts of the Caulkins, Parrish, Hoecker and Lincoln gullies and in all accessible ravines of the Naples and southern parts of the Middlesex valley. Along Can- -andaigua lake they are seen in the upper parts of the deeper ravines on the west side, south of the Academy tract, in Bris- tol valley in the upper parts of all the ravines between Boswells Corners and Bristol Center and in the Honeoye valley just west of the sheet between Hunts hollow and the Briggs gully. Grimes sandstone Compact or laminated, light bluish gray sandstones in layers 4 inches to 3 feet thick, separated by hard, blue gray shales. In the vicinity of the Tannery gully, 4 mile south of the village of Naples, a part of the sandstone is highly calcareous owing to the presence of masses of molluscan shells, mostly in comminuted condition. Thickness about 50 feet. In the face of the precipice at the third falls of the Grimes gully and ex- posed in the escarpment on the east side of the ravine 10 feet above the water, is a thin layer of soft shale which has been found to containBuchiola retrostriata, Muantico- ceras pattersoni, Bactritesand other typical members of the Naples fauna. This is its highest appearance in this sec- tion. Twenty-four feet higher and 9 feet below the crest of the falls occurs the Grimes sandstone which bears a brachiopod fauna with Liorhynchus, Atrypa reticularis, Productella, CANANDAIGUA AND NAPLES QUADRANGLES 35 Ambocoelia, Leptostrophia mucronata, etc.;- the first appearance of this fauna in this section and to be re- garded as an incursive appearance of the Ithaca fauna lying farther to the east. This formation lies 599 feet above the base of the Middlesex black shale and this is the thick- ness to be ascribed to the Portage formation in this merid- ian as formerly defined. In the Tannery gully on the east side of the Naples valley the upper beds have afforded a number of singular organisms associated together but not con- curring with species of the characteristic Naples fauna. These are specially noted elsewhere and consist of the fossil Parop- sonema, believed to be an aberrant echinoid, some forms of annelids described as Protonympha and Palaeochaeta, also a large Orbiculoidea, some strange and undescribed linguloids, etc. The division occurs also at the Naples reservoir, in the escarpment on Hatch hill, in the Caulkins gully and the quarry near it, at the top of the dugway on the Hunts hollow road, in the road near Freeds and along the hillside northward to Rhinestreet, also near the Muck place on Seaman hill and in the small ravine near the Gardner property, 2 miles north of Bristol Springs. In Bristol hollow it appears in the upper parts of the Randall and Reed gullies and on the north side of Worden hill; in the Honeoye valley on the hillside above E. Alger’s property and northward to the upper part of the Briggs gully. West Hill flags and shale Light bluish gray sandstones or flags from 2 to 12 inches thick, separated by beds of dark blue, olive or black shale. The sand- stones are sometimes quite calcareous owing to the presence of crinoid stems and other fossils usually in fragmentary condition. Thickness 550 feet. This heavy mass of arenaceous deposits like the Hatch beds below is partially equivalent to the Gardeau series of Hall as developed in the Genesee valley. It has however undergone a change faunistically, and remains of the Naples fauna are now no longer seen, though the rocks contain fossils in some measure; but these are largely brachiopodous and indi- cate continued presence of the Ithaca fauna. The sandstones are 36 NEW YORK STATE MUSEUM quite sharply distinguished from the Grimes sandstones below on account of their thinner bedding and bluish color. This divi- sion is exposed in Italy hollow at the south end along Flint creek and in the Italy gully, in the Naples valley in the Tannery gully and Grimes gully. It is found on the south side of the road leading easterly across Deyo basin, 2 miles south of Naples, 5 or 6 rods from the Ingleside road and near the foot of the hill. Here it is an isolated exposure and its stratigraphic position can not | be ascertained with precision. It is however not far from 100 feet above the top of the Grimes sandstone. At this spot it has produced a number of interesting fossils; Hydno- ceras tuberosum, H. variabile, Ceratodictya cincta, MHysteracanthus, Spirifer mesacostalis, Atrypa hystrix, Productella, Ambocoelia etc. The same horizon is found near the residence of Charles 8. Sutton on the north side of the road leading from Naples to West hollow and here also brachiopods are found. The same beds are seen on the lands of the Pottle estate, 14 miles north of the last named ex- posure. One of the sandstones here contains fossils in great abundance, principally of the same species as found in the Deyo basin and on the West hollow road. A survival of the Naples fauna is notable here in the presence of the species Manticoceras. oxy. In the road leading northward on the top of Worden hill a ledge of sandstone is exposed on both sides that contains masses of brachiopods. This locality is about 1 mile north of the south line of Bristol township. On Hatch hill are outcrops in the lower part of the so called Three Cornered clearing near the top. The rocks are also seen at the upper end of the Hoecker and Lincoln gullies and on the hill north of the Seaman schoolhouse, and in many small ravines on the sides of High point, Frost hill and Gannett hill. They are also the sur- face rock over the principal part of the town of Canadice to the west of the sheet and extend over the tops of the ridges on both sides of the Bristol valley for-a mile or two into the town of Bristol. CANANDAIGUA AND NAPLES QUADRANGLES 37 Highpoint sandstone Light gray sandstones in layers from 3 inches to 4 feet in thickness separated by thin beds of hard blue shale. Some of the layers of the rock are compact and calcareous but the larger portion is laminated and sometimes shaly. Lenticular beds of impure limestone composed of crinoid stems and other fossils occur at High point and other outcrops. These sandstones are thinner and softer toward the east. Thickness 100 feet. These beds are nowhere sufficiently exposed to admit of detailed exam- ination of the entire series and the upper and lower contact, but 50 to 75 feet of the formation project in the cliff at the south end of High point at an elevation of 1850 to 1925 feet A. T., and the talus that covers the strata at the base of the hill is principally composed of fallen slabs and blocks of the sandstone. In structure, texture and general appearance they differ from the Grimes sandstone only in being somewhat coarser and weath- ering to a lighter color but they likewise differ notably in their fossil contents. Fucoides verticalis, which is not seen in the lower rocks, is common throughout these beds. The most striking feature of this exposure consists of an irregular stratum of calcareous sandstone and conglomerate 7 feet thick where thickest and thinning eut gradually around both sides of the hill. This is a mass of brachiopods, corals and crinoid stems cemented into a hard, compact layer that resists the effects of weather and at one place projects 12 feet beyond the soft sandstone beneath it. Several fallen slabs of this calcareous layer 10 to 15 feet across are to be seen at the foot of the escarpment and many others have been broken up and utilized in the construction of fireplaces in the pioneer days and later in the arches of furnaces beneath steam boilers, its resistance to the disintegrating effect of heat making the “ High Point firestone” highly esteemed for these purposes in this locality.- It has, however, now fallen into disuse. This highly fossiliferous layer is about 50 feet below the top of the sandstone. In it a well defined Chemung fauna with Spirifer disjunctus occurs together with species 38 NEW YORK STATE MUSEUM which were originally described from the upper Deyonic beds of Iowa, and attention is here directed to a more complete state- ment of the fossil contents of these beds in a subsequent para- | graph. The rock is not exposed on the south or west sides of the depressions that isolate High point, though calcareous layers of somewhat similar character occur at about the same horizon in the cliff on the northwest end of Knapp hill and also in the escarpment near Mr J. Eldridge’s residence on the road from Garlinghouse to Atlanta. Hard, dark shales and thin sandstones come in again at the top of the High point bluff and are slightly exposed in the fields above but no fossils were observed in them and nothing but their position distinguishes them from those below. On the south side of the Naples valley the Highpoint beds appear in some isolated outcrops on the north slope of Pine hill and in the bluff on the west side of Knapp hill and the thick sandstones that form the escarpments above the talus in the vicinity of McClarie’s quarry on the dugway road just east of North Cohocton are in the same horizon, but the rock here is almost barren of fossils. They are also to be seen in Lyons hol- low by the side of the road leading east, 2 miles south of Ingleside; in the upper part of Italy gully and on the tops of Worden and Gannett hills. Careful stratigraphic work has determined that the Highpoint sandstone is continuous with the original Portage sandstones of the Genesee valley, which in Professor Hall’s sec- tion capped the Portage section there. It has also been pointed out that while these horizons are stratigraphically continuous the fauna is very different in the two sections. The Portage sandstones still carry the Naples fauna, while in the Naples region that fauna has long before this date been extinguished by the appearance, first of the Ithaca, then of the Chemung fauna from the east. Prattsburg sandstone and shale In the lower part of this division the sandstones are mostly olive-gray, rather soft and schistose or in thin even layers, and the shales are in part soft and blocky, similar in appearance to the Cashaqua shales. Layers of blue, olive and black shales occur. CANANDAIGUA AND NAPLES QUADRANGLES 39 Thickness from 200 to 225 feet. These beds lie in the horizon of the Wiscoy shales of the Genesee river section, which are beds there overlying the Portage sandstones but still carrying the Portage fauna though somewhat modified in character. There also they are overlain by strata carrying the Chemung fauna which appears first at Long Beards riffs with Spirifer disjunctus. . The upper part of the Prattsburg beds in the Naples region are light bluish gray sandstones, usually in lentils and compact or uneven layers. The interstratified shales are mostly blue and hard, but black and slaty layers occur frequently. These beds have a thickness of 300 to 400 feet in the higher land of the southern part of the quadrangle. The lower portion, or the equivalent of the Wiscoy horizon, is exposed in a small outcrop on the road leading from Marsh’s Corners southward up Pine hill near the top, and a mile still farther east on the road leading from Ingleside to Lent hill is another exposure in approximately the same horizon, from which Manticoceras oxy has been obtained. Whitney’s quarry on the southwest side of Pine hill, which has produced a large amount of flagstone laid for sidewalks in the village of Naples and adjoining towns, is in this horizon. It is exposed also along the dugway road leading up Lent hill _ southwest from Ingleside near the road on the east side of Pine hill, in the Woodworth quarry 2 miles south of North Cohocton, on Lent hill in the ravine west of the Wheaton farm, in the upper part of the Italy gully, and by the roadside 2 miles north of Prattsburg. The upper beds are seen in the Wheaton quarry on the hill south of Atlanta, by the roadside in several places in the vicinity of Lent Hill church and in numerous small outcrops on the high ridge between the Prattsburg valley and Lyons hollow. 40 NEW YORK STATE MUSEUM SUCCESSION OF FOSSIL FAUNAS Camillus shale We know of no traces of organisms in these deposits except an occasional ostracode shell (Leperditia) and a trail made on the soft mud by such an organism. The sediments were laid down in a sea too shallow and too strongly saturated with brine and alkalis to encourage the existence of life. Bertie waterlime The fauna of these beds is that peculiar association of crusta- ceans which has made this horizon one of the most interesting in the entire series of the New York formations. Occasionally in the outcrops and more freely in the loose blocks of this rock scattered over the country south of the line of outcrop, are specimens of Eurypterus remipes Dekay and Cerat- iocaris acuminata Hall, with abundant Leperditias, Lingulas and an occasional Orbiculoidea. Westward of this region specially in the exposure in the quarries of the Buffalo Cement Co. at Buffalo, and eastward in the towns of Sauquoit and Litchfield, Herkimer co., these crustaceans with others are found in great abundance and. perfection, but in the intervening region they have thus far proved of rarer occurrence. The fauna of these merostome crustaceans is widely known as one marking the closing stages of Siluric time through northern latitudes on both hemispheres. | Cobleskill shale and dolomite The fauna here is sparse but indicative of the relation of the horizon to its more typical eastward outcrops. The list of species at present known is: Eurypterus, occasional fragments Spirifer eriensis Grabau | Leperditia alta Conrad Cyathophyllum hydraulicum Stmp- L. scalaris Jones son Whitfieldella suleata Vanuxrem Oriskany sandstone This rock carries no fossils in this district.

Onondaga limestone Throughout the exposures of this rock fossils are abundant but they are not easily obtained because of the difficulty in setting them free of the matrix. Experience has shown that the endeavor to acquire the remains from the unweathered exposures is for the most part fruitless as well as arduous except where there are shale masses intercalated between the limestone beds. The fauna is specially profuse in corals but the agglomerations of these or- ganisms which are seen in the lower beds of this district become immense coral plantations farther westward in the vicinity of Leroy, Genesee co. Nature has helped to solve the difficulties at- tending the extraction of these fossils by scattering over the county and through the soil southward innumerable blocks of this rock. The corals are partially silicified in the bed and on exposure become more so and the dissolution of the calcareous matrix makes the occurrence of silicified corals of this formation extremely common over much of the region covered by this map. The layers of the limestone that are associated with and more or less impregnated by the chert, weather into all sorts of irreg- ular shapes according to the degree of dissemination of the lime throughout them and when this silicious rock has become thoroughly “rotten,” that is, has lost all its-lime, the silicious residuum retains with minutest precision the impressions of the organic contents. By the examination of such masses of rotten stone has the fauna in an important degree been made out, and an illustration of their significance is seen in the fact that these masses from Ontario county produced specimens of trilobites alone of which 55 drawings were made for the monograph of these organisms published as volume 7, Palaeontology of New York. In these weathered blocks students of this fauna will find their material in most suitable form for study; these will not however 42 NEW YORK STATE MUSEUM contribute to a knowledge of the zonal distribution of the species. Of this condition we know little; probably variations in range are so slight that the effort to ascertain them would produce a result in no way commensurate with the labor involved.

The Marcellus shale introduces black, carbonaceous and pyritous sedimentation, evincing a deepening of the waters and a foul bottom, over which but few forms of life prevailed and these depauperated in size and of very tenuous shell. All the species here found are the apparent proper accompaniments of such bionomic conditions; Liorhynechus limitaris, which puts in an appearance during this stage of the Devonic wherever the sediments become highly charged with bituminous matter; Chonetes mucro-. natus, C.lepidus, Strophalosia truncata, Plew- rotomariarugulata, Styliolina fissurella and Orthoceras subulatum also follow these conditions.

There is in the former as a most striking feature the profuse development of the crinoids associated with an almost equal profusion of Phacops rana, Diaphorostoma lineatum and Pentamerella pavilionensis with Productella papulata; in the upper beds lamellibranch species such as Orthonota undulata, parvula, carinata, Phthonia nodocostata, Pholadella radiata and specially Tellinopsis subemarginata which are rare or absent below. There are also here thin beds wholly composed of Ambocoelia umbonata but on the whole the distribution of the fauna throughout the Moscow shales is quite uniform. The Moscow shales are exposed in detail in the ravine at Tichenor point where the succession from the bottom up is essentially as follows: At the base the uppermost beds of the Canandaigua shales with Eridophyllum archiaci, MHeliophyllum and other cyathophylloids in abundance. Tichenor limestone 1 Blue calcareous shale with crinoids, Pentamerella pavilionensis, Diaphorostoma lineatum, Phacops rana, 2 feet, passing into a thin limestone 8 inches 2 Bluish shale with Tropidoleptus carinatus, 30 feet 3 Menteth limestone, 1 to 14 feet 4 Bluish shale with Tropidoleptus carinatus d Olive shales with Cryphaeus boothi 56 NEW YORK STATE MUSEUM 6 Arenaceous shale with Homalonotus dekayi, Or- thonota, abounding in grotesque calcareous concretions and passing into a thin limestone above, 12 feet 7 Olive shale | 8 Very soft light gray shales with Ambocoelia, Chonetes, Athyris and Phacops in distant thin layers 9 Olive shale Tully pyrite Genesee shale Tully limestone and pyrite What little Tully limestone is here represented carries the indicial species Hypothyris cuboides Sowerby (sp.) identified originally by Conrad with Sowerby’s Rhyncho- nella cuboides and subsequently described by Hall as R. venustula. The species R. cuboides was long ago referred by King to the genus Hypothyris. This world-wide species is here a newcomer into the Devonic faunas and is associated through- out the exposures of the Tully with an assemblage essentially consisting of Hamilton species, though slight variations from Hamilton types are indicated and there are a few additional species present like the very characteristic trilobite Bron- teus tullius Hall & Clarke. For at least a half century Hypothyris cuboides has been recognized as indicative of lowest upper Devonic age and the Bronteus associated with it is likewise of early Devonic type (Thysanopeltis). The fact that these species accompany an essentially unmodified fauna of earlier age does not argue that age for the limestone but serves to emphasize if anything the introduction of new types indicative of fundamental change. The fauna of the pyrite layer is a parvifauna with affinities wholly or essentially with that of the Hamilton shales. It is in fact a series of forms which have as a whole suffered an arrest of development, and its species are immature stages of those preceding though they are actually in adult condition. The conditions of growth while this pyrite was being precipi- CANANDAIGUA AND NAPLES QUADRANGLES 57 tated, were so unfavorable that the organisms were able to advance but a little in the line of species development and yet they apparently acquired the power of reproduction and mani- fested themselves in these arrested conditions probably for several generations. These fossils were studied by the writer some years ago, and have been more exhaustively examined of late by Dr F. B. Loomis from material collected all along the line of outcrop of the layer. The specimens are to be extracted from the rock only with great labor but it is to be expected that: forms present at one place will appear at others and hence the entire list of the known species is here appended. It will be observed that the cesignations used in Dr Loomis’s list here given indicate muta- tions only from the types of Hamilton species and not deep seated specific differences.

It is thus a prenuncial fauna announcing the invasion and occupancy of the field by a congeries of species not before known in New York. It is evident that this fauna came in from the west and covered for a short time only, the whole area from here westward to Lake Erie. We have shown elsewhere the probability that the rock itself, which is largely composed of the pteropod Stylio- lina, represents a deep water deposit of pteropod ooze and its associated organisms are also those of deep water habit. The fauna and flora of this limestone are as follows and in this list the CANANDAIGUA AND NAPLES QUADRANGLES 59 names in roman are of species reappearing in the higher faunas (Cashaqua); those in antique not occurring elsewhere.

Cashaqua shale In these soft shale beds, with their accompanying flags and sands, the peculiar western Portage fauna attains its culmina- tion. This interesting congeries of fossils has been termed the Naples fauna for it is here that it attains its best development. The term has been employed because of the indefiniteness of the term Portage as applied to the fauna, for the faunas existing in Portage time are known to differ highly according to their geographic location; brackish in eastern New York (Oneonta), a profuse brachiopod fauna in central New York (Ithaca) and in western New York a fauna essentially devoid of brachiopods but characterized by its abundance of cephalopods and lamelli- branchs. In our latest studies of this fauna in its extent throughout western New York it has become evident that, in this western Portage province covering the field occupied by the fauna from Cayuga lake west to Lake Erie, the Genesee prov- ince as it has been designated, there are actually two subprov- CANANDAIGUA AND NAPLES QUADRANGLES 61 inces, an eastern (Naples subprovince) into which only the ad- vance guard penetrated on its invasion from the west, and a west- ern or Chautauqua subprovince. These two subfaunas of the Genesee provinces are knit together by unity of generic and to some extent of specific characters, but differ more in respect to predominant species. We have then in the rocks before us the typical development of the fauna of this Naples subprovince or the Naples fauna in its proper sense.

The rock is continuous nearly across the map and beyond it to the east. Rhinestreet shale In these recurrent beds of black shale the fauna is again very much curtailed. Only the following have been obtained from it: Polygnathus dubius Hinde Spathiocaris emersoni Clarke Prioniodus spicatus Hinde Lunulicardium velatum Clarke P. erraticus Hinde Pterochaenia fragilis Hall Palaeoniscus devonicus Clarke Leptodomus multiplex Clarke Acanthodes pristis Clarke Hatch flags and shales The fossils in these arenaceous beds are all representatives of the Cashaqua shale fauna but in very much decreased quantity. Goniatites, specially Manticoceras pattersoni and Probeloceras lutheri occur in the flagstones, also occa- sional specimens of Lunulicardium ornatum and L. CANANDAIGUA AND NAPLES QUADRANGLES 63 acutirostrum, Honeoyea desmata and Buchi- ola retrostriata, Palaeotrochus praecursor and Bactrites. In certain layers fragments of plants abound, chiefly of Lepidodendron. Grimes sandstone The Portage or Naples fauna has now disappeared except for a few straggling and modified representatives in the higher rocks and with the Grimes sandstone appears a well defined though somewhat sparse brachiopod fauna. We originally regarded this small fauna of the Grimes sandstone as a representative of the Chemung fauna but have subsequently expressed the view that it is rather the invading Ithaca fauna from the east. The distinction is a refined one; it would be extremely difficult to indicate at what time or horizon in the succession the term Che- mung is to be applied to the homogeneous fauna occupying the field of central New York during the upper Devonic. The fauna of the Grimes sandstone is as follows: Protonympha devonica Clarke Leptostrophia mucronata Vanuxem Palaeochaeta salicifolia Clarke Chonetes lepidus Hall Conularia cf. continens Hall . Liorhynchus mesacostalis Hall Paracyclas sp. L. globuliformis Vanuzxem Grammysia subarcuata Hall Productella lachrymosa Hall Aviculopecten cf. cancellatus Hall Ambocoelia umbonata Conrad Sphenotus sp. Atrypa spinosa Hall Orbiculoidea Paropsonema cryptophyum Clarke Schizophoria impressa Hall Dictyospongia haplea Hall & Clarke West Hill flags and sandstone The fauna of these beds is a continuation of the brachiopod fauna of the Grimes sandstone with some interesting additions. Nowhere are the fossils abundant and none are specially dis- tinctive of the Chemung fauna so that we may regard these beds also as a continuation of the Ithaca invasion from the east. The fossils recorded are as follows: Manticoceras oxy Clarke Grammysia elliptica Hall Palaeotrochus praecursor Clarke Pholadella cf. parallela Hall Aviculopecten cancellatus Hall Leptodesma robustum Hall 64 NEW YORK STATE MUSEUM Stropheodonta cayuta Hall | Ambocoelia umbonata Conrad Leptostrophia perplana Conrad var. | Cyrtina hamiltonensis Hall nervosa Hall | Liorhynchus mesacostalis Hall Orthothetes chemungensis Conrad Hydnoceras tuberosum Conrad Productella lachrymosa Hall _H. variabile Hall &€ Clarke Spirifer mucronatus Conrad mut. =H. legatum Hall &é Clarke S. mesacostalis Hall _ Ceratodictya annulata Hall Atrypa hystrix Hall | Hydriodictya cylix Hall € Clarke High Point sandstone The interesting fauna of the calcareous or firestone layer of this formation was studied some years ago by the writer and its species have not been increased by later observations.

It is also important to note the very marked representation of species which were orig- inally described from the upper Devonic of Iowa and have been observed nowhere else in the Appalachian region except spas- modically. Exact correlation of the stages of the Iowan Devonie with that of New York is not practicable as the Siluric continental barrier between was the cause of great differences in sedimen- tation and fauna on its east and west sides, but this invading western fauna intercalated in the normal Chemung fauna of oe ‘ q CANANDAIGUA AND NAPLES QUADRANGLES 65 this district may be regarded as an indication of the fact that the continental barrier was temporarily down and the western fauna migrated to the east. Prattsburg sandstone In these beds the fauna, which is fairly profuse in certain layers, does not materially differ from that of the West Hill beds. The Iowan species occurring in the High Point fauna are not present or if so are of extremely rare occurrence and certain species are abundant such as Spirifer mesastrialis Hall Atrypa hystrix Hall S. mucronatus vonrad var. posterus | A. reticularis Linné Hall & Clarke Stropheodonta cayuta Hall In certain of the beds from the upper part of the division occurs the trilobite Bronteus senescens Clarke, which has also been found as far south as Avoca, Steuben co. in the continuation of the same formation.

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 Amer- ican museum of natural history in the city of New York. Till the prep- aration of this catalogue was begun, no serious effort to bring together the type specimens in the state museum 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 Crus- tacea, Vermes and Cephalopoda.’ But a revision of these lists has shown considerable omissions, due somewhat to normal growth as inves- tigations 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 the 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 on it. ) This catalogue is arranged as follows: the general classification is biologic and follows only the broadest subdivisions. Each entry repre- sents a single specimen and is accompanied by two numbers, the first serial, the second fractional and corresponding to the number borne by the specimen. In this fractional number the numerator carries the num- ber 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 the num- ber 2284, 2000 is the number assigned to the Sfongiae, 2260 that assigned to the genus Dictyospongia, 2264 the number for D. » sceptrum, the fourth species of that genus, and **4 the number for the second specimen of this species. In the scheme of numbering the following is the allotment made for the major biologic divisions : Plantae. 60), 290s 2% 100 Lamellibranchiata..... gooo Pfovozoay,, F221. 444 1000 Gastropoda ..... ».+«. 10000 Sponpiae !.05 NVQ. 2000 Pteropoda .

TYPE SPECIMENS OF PALEOZOIC FOSSILS 5 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 alphabetic 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 catalogue, a period of 18 months, the continuous publication of paleontologic researches and acquisitions to the collections by gift and purchase have notably increased the number of type specimens and these have been added in a supple- mentary list brought up to February 1903. 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. .

CLarKeE State Paleontologist Bulletin 69 PALEONTOLOGY 9 REPORT OF THE STATE PALEONTOLOGIST 1902 To the Regents of the University of the State of New York I have the honor to report herewith on the work of this depart- ment during the year commencing Oct. 1, 1901. Operations in the field 1901-2 Guelph horizon and fauna. In my report of last year I had occasion to make reference to investigations relating to the distribution of the Guelph horizon and its fauna throughout western New York. This interesting congeries of fossils, con- stituting essentially a new element in the Paleozoic faunas of the New York series of geologic formations, had at that time - been found only in the vicinity of Rochester, with the exception of an early locality in Wayne county mentioned by Professor Hall in 1843, but subsequently lost. As noted in the report referred to, our effort of that year to locate other manifesta- tions of this horizon between Rochester and Niagara Falls along the summit of the Niagara escarpment was not successful in its main object, though contributing interesting data bearing on the contact outcrops of various formations immediately involved. The horizon of the Guelph lies so involved with the upper beds of the dolomite series which constituted the closing episode of the Niagaran stage in New York, and these dolomites are, notwithstanding their massive and resistant character, so seldom exposed in continuous section, that the few natural cliff exposures through this region are very unsatisfactory for the determination of the contents of the strata. — 852 NEW YORK STATE MUSEUM Early in the present season, however, an artificial exposure along the banks of Oak Orchard creek directly south of Shelby, Orleans co., was reexamined and found to contain evidence of the Guelph fauna for which we had been diligently searching. Here a channel has been cut through the natural rock bed of the creek in the construction of a feeder for the Erie canal and drainage way from the Oak Orchard swamp lying to the south, and, taking the exposure at low water and before the vegeta- tion had become profuse, it was practicable to make out the succession of the dolomite series with clearness and also to locate therein two horizons of the Guelph fauna, the lower of which has proved remarkably prolific in organic remains and these of extraordinarily interesting character, supplementing very materially the knowledge we had already derived of this fauna from its development in and about the city of Rochester. It would appear from a closer analysis of these aggregations that the upper Guelph horizon, which lies 30 feet above the lower, is to be correlated with and doubtless is coextensive with that at Rochester. Following this discovery, the attempt was renewed to locate the horizon at other localities, specially in the continuous section at Niagara Falls, and, though here the section is essentially a vertical one and the rocks difficult of access, the effort to locate these horizons in that section proved successful. Similarly, at various localities from Niagara Falls to Shelby near and south of Lockport, Gasport and Middleport, the horizons were followed, and also west of Shelby in the towns of Barre, Clarendon and Byron, at Claren- don there being an exposure of considerable continuity. At none of the localities, however, except at Shelby were the horizons found to be fossiliferous except in the presence of an occasional species of this characteristic fauna. The problems presented by this fauna, both biologic and stratigraphic, have been carefully studied and are embodied in Memoir 5 of the State Museum, which is now essentially printed, and to which reference is made under another head. The fauna of the Naples beds. In order to help to a conclusion a monograph now long standing, on the Naples fauna of the Portage stage in western New York, one part of which has already been published, Mr D. D. Luther carried on investiga- _— REPORT OF THE STATE PALEONTOLOGIST 1902 853 tions in Erie and Chautauqua counties. This study has in- volved some questions in regard to the determination of the upper boundary of the Portage formation which can be fixed only on the basis of the evidence to be derived from the fossils. The organisms themselves are also for the most part undescribed and constitute one of the remarkable associations of fossils in our older rocks. The fauna of the western New York Portage or the Naples fauna has been shown to have entered the State from the west and not to have penetrated far beyond the meridian of Cayuga lake. Its path of migration into the western boundaries of the State is evidently buried at the bottom of Lake Erie; but, to determine whether any trace of the fauna is to be found to the south or north of the lake, some investigations were carried on in Erie county, Pa. to ascertain the significance of the formations termed by the Pennsylvania geologists ‘“ Portage” and “Girard shales.” The Portage, it has now been made evident, does not there exist, and the faunistic value of the Girard shales is a matter for further study. In Ontario the black shale beds at Kettle Point, Lake Huron and about Sarnia, Forest and Alvinston, which have been recorded as of Portage age, show no definite relations to the true Naples fauna, but rather represent only the con- dition which prevailed during the deposition of all the black muds of the Genesee and lower Portage stages. All these field operations undertaken during the early part of the season were greatly embarrassed by the tremendous and protracted rainfall, which flooded the watercourses of the country to such a degree that they became virtually inaccessible, and for some weeks it was necessary to discontinue field work altogether. The study of the Naples fauna is now brought to virtual con- clusion, and the manuscript for some portion of it is in the printer’s hands for a memoir of the State Museum. Brief refer- ence will be made to this also under the caption of office work. The “Hudson river ” formation and faunas of eastern New York. In continuance of his previous investigations of the “ Hudson River ” formation, accounts of which have appeared in various museum bulletins and reports of the paleontologist, Dr R. Ruede- mann was engaged in Rensselaer and Washington counties. The construction of a tunnel for the extension of the water 854 NEW YORK STATE MUSEUM supply of the city of Troy is affording a section rather more than 1 mile in length through the shale region north of the Tom- hannock river and, by the courtesy of Prof. W. G. Raymond, engineer in charge of these operations, we have been permitted to examine the section in all its parts in great detail as the rock is taken out. This section has already furnished some fossils which indicate the geologic age of the shales through which it runs; but, for the most part, the rock section has proved there, as usual in most exposures of the eastern Hudson river shales, comparatively devoid of these conclusive evidences as to its geologic age. The discovery of a profuse graptolite fauna at the Deep kill, Rensselaer co. as noted in my last report, wherein are repre- sented the three zones of the Phyllograptus shales of Europe or the lowest part of the Lower Siluric, has suggested the pos- sibility of producing a map of that region on which may be distinguished all the graptolite bands of the Lower Siluric shale facies. During the present season investigation toward this end has covered the southeastern part of the Cohoes topographic sheet, with the Hudson and Hoosic rivers as western and north- ern boundaries respectively. A discovery of considerable importance for the correlation of the shales throughout this region was made incidentally in the finding, in the vicinity of Schaghticoke, of the horizon of the fossil Dictyonema flabelliforme_ with associated species, all of which are regarded as indicating throughout northern Europe, and wherever found, the top of the Cambric series. This horizon has not before been found within the United States. This is a distinct contribution to the faunas heretofore represented in the New York series. The areal map of the Tully quadrangle. The work on this quad- rangle was virtually done during the previous season; but it seemed, on careful revision of the map prepared, that the strati- graphic divisions were insufficiently detailed, and, to carry out a more minute subdivision of the strata based more specially on paleontologic evidence, the work has been reviewed and is now brought to a satisfactory completion. Work on the Elmira quadrangle; cooperation with the United States Geological Survey. Under the same conditions as have REPORT OF THE STATE PALEONTOLOGIST 1902 855 heretofore prevailed in developing the stratigraphic and paleontologic relations on the Olean and Salamanca quad- rangles, we have this year carried forward to completion, in cooperation with the United States Geological Survey, similar work on the Elmira quadrangle. On this work Messrs Myron L. Fuller and F. G. Clapp were detailed by the director of the United States Geological Survey, and this department was represented by C. A. Hartnagel and H. S. Mattimore in the necessary collection of fossils. The area covered by the Elmira quadrangle being in some degree lower down in the rock series than the areas of the Olean and Salamanca quadrangles, the questions which there arose in regard to the classification of the culminating geologic horizons have not been revived in this case. Most of the territory about Elmira is underlain by rocks of the Chemung stage, though at the north, in the low lands and valleys, are small, restricted areas of the Portage formation directly underlying. Sections however do not rise to any considerable hight, so that the hill summits do not enter on the horizons of the Wolf creek, Salamanca or Panama con- glomerates. On account of the simplicity of the stratigraphic problem here involved, the time required for the field work was not long. The area between the Elmira and the Olean quad- rangles is as yet but partially surveyed, and no maps have been made available for stratigraphic work, but it is on these inter- vening quadrangles that we may expect to find additional and important light on the problems which have arisen in the detailed study of the geologic succession in Cattaraugus and western Allegany counties. The fauna and stratigraphic relations of the Coralline or Cobleskill limestone. ‘‘Coralline limestone” is a term applied by Prof. James Hall to a fossiliferous formation in eastern New York which he believed to be the eastern extension of the Niagara or Lockport dolomites of the Upper Siluric. The name was not one of the original elements in the nomenclature of the forma- tions as proposed by the four geologists, though the term was originated by and had been in local use by John Gebhard, the pioneer of geology in the region about Schoharie county where this formation is best developed, and was also employed by 856 NEW YORK STATE MUSEUM Mather in describing the rock series exposed at Rondout, Ulster co. This formation, which is in typical section in Schoharie county, as at Howes Cave and along the Cobleskill, is a dark limestone abounding in corals and carrying a considerable fauna besides, which has been described by Hall in volume 2 of the Paleontology of New York. It is underlain in this section by a mass of 30 to 50 feet of soft gray shales and, further east along the Schoharie creek, this mass is lessened and the shale is of greenish color. Professor Hall regarded this underlying shale as pertaining to the Clinton formation, and, on account of the stratigraphic position of the Coralline limestone and because of the nature of its fossils, many of which he found to be identical with or similar to known Niagara species, he con- cluded, as above stated, that it was an eastern representative of the Niagaran formation not otherwise known in this part of New York State. The value of this determination has been brought into question by several writers, specially as a more careful study of the fauna of these beds indicates, notwithstand- ing its affiliations to the Niagara fauna, specific identities of notable importance with species which occur in higher horizons in the State of New York. Thus we have observed that, above the waterlime formations at the top of the Salina stage in western New York, probably 1000 feet higher than the last appearance of the Niagaran fauna, species occur which are identical with the Coralline limestone species of eastern New York, and these points of similarity have been quite clearly pointed out in a recent publication by Prof. A. W. Grabau. We have had previous occasion also to direct attention briefly to the occurrence of a profuse development of a fauna similar in many particulars, in a quite pure limestone interbedded be- tween the upper and lower waterlimes of the Salina formation at Frontenac island, Cayuga lake. Now, though the Coralline limestone with its characteristic fossils appears in Schoharie and Otsego county sections to lie below the waterlime forma- tion as a whole, in the sections exposed at Kingston and Rondout and early described by Lieutenant Mather in his report on the geology of the first district, the formation and its fauna apparently make a double appearance, lying at first below the i. REPORT OF THE STATE PALEONTOLOGIST 1902 857 cement rock, as at Rondout, and then reappearing after the deposition of a considerable thickness of waterlimes, and the second appearance followed again by more of the cement rock. The lowermost of these beds is not the equivalent of the typical or Schoharie county Cobleskill but its fauna carries a much stronger impress of Niagaran age. We are compelled, for purposes of correlation east and west, to designate this bed by a distinctive term and shall call it the Wilbur limestone. The Cobleskill beds on Cayuga lake at Frontenac island are involved in somewhat similar stratigraphic condition to the upper bed or true “ Coralline ” at Rondout. We had undertaken a few years ago to work out the various bearings of the data set forth by this interesting fauna and formation,-. specially its manifestations in central and western New York. During the past season field studies have been carried forward in the eastern part of the State. It is too soon to state definitely the outcome of these investigations; but this much is clear at the present time, that the fauna of the Coralline limestone, in its first appearance in the Rondout section, contains an important percentage of species which have very close relations even to identity with species of the Niagara dolomite. This resemblance is essentially lost in the higher horizon at Rondout which is equivalent to and probably continuous with the typical Coralline outcrops in Schoharie county. Several of these very character- istic forms occur in the Guelph fauna, which we have elsewhere described, and others, as just noted, reappear in a still later manifestation, in fact the final stage of the Siluric faunas in western New York. In the proper interpretation of the strati- graphic relations of these faunas much will depend on the valua- tion of the beds which underlie the limestone in the Schoharie county sections, and which were called and have heretofore been commonly granted to be of Clinton age. , Messrs Ulrich and Schuchert put forward, in the last annual report of the paleontologist, in an important paper entitled Paleozoic Seas and Barriers in Eastern North America, the hypothesis that, during this late Siluric period, a land barrier crossed New York State from northeast to southwest, and that the Coralline fauna was a provincial development pertaining to the region outside or eastward of the barrier, while other phases 858 NEW YORK STATE MUSEUM of late Siluric faunas were holding the ground on the inner or mediterranean side. The arguments in support of such a barrier in eastern New York during various epochs of Paleozoic time are strong and have been well constructed by the authors referred to. Their hypothesis proves of great service in properly construing the long known and palpable difference in the development of the Paleozoic rocks in eastern New York and in the central and western parts of the State. We are disposed to believe that the complete analyses of the proposition now before us concern- ing the value of the Coralline limestone and fauna will throw important light on the existence and influence of such possible land barrier during late Siluric time. We have above and previously used the expression, “ Cobleskill limestone,” as an alternative name for this formation, in view of the fact that stratigraphic names seem to meet modern require- ments only if designated by geographic terms. The term “ Coral- line” is unfortunate in many respects; it originally had reference to the abundance of corals in the rock, but the word is now used with a different signification, and, while it has no geographic value, it has neither the biologic importance which such term should carry. The Cobleskill presents the best sections of the formation to be found in the region of its typical exposures. Mr ©. A. Hartnagel, who has been specially concerned with the study of this problem, communicates the following account of his field operations: Work on the Cobleskill formation. This report is a brief account of the field work during the greater parts of the months of August and September, on the Cobleskill forma- tion. For convenience the region studied is here considered in three sections. First, that extending from Gallupville, Schoharie co., west and northwest through Shutter’s Corners, Schoharie, Howes Cave, Central Bridge, Grovenor’s Corners, Car- lisle, Sharon Springs and the section to the north and northwest of Cherry Valley in Otsego and Herkimer counties. Second, that section in Albany county, along the northern and eastern ends of the Helderberg plateau, extending from Altamont, and including the Indian Ladder and New Salem sections, to South Bethlehem. Third, the section extending from Catskill in Greene county, south REPORT OF THE STATE PALEONTOLOGIST 1902 859 through West Camp, Saugerties, Glasco, Lake Katrine, East Kingston and Kingston (Rondout). From Kingston this section extends southwest through Wilbur, Eddyville, Whiteport, Binne- water, Rosendale to High Falls, all in Ulster county. 1 Gallupville. On the left of the road leading north past the cemetery, from Gallupville, at a distance of 144 mile from the village, there is exposed, though somewhat obscurely, the Cobles- kill formation together with the underlying Salina shales. The Lorraine shales are well shown here, as is the Rondout series above the Cobleskill. This is the only section where the Cobles- kill has been observed north of the Fox kill. Professor Prosser, at a point farther west, near Shutter’s Corners, has observed the Rondout, but a careful study of the vicinity did not reveal any outcrop of the Cobleskill. Shutter’s Corners. One half mile south of Shutter’s Corners on the farm of Seth Stevens, occurs an outcrop of the Cobleskill. The weathered condition of the rock at this station has made it favorable for collecting, though here and continuing for more than a mile westward the vicinity of the outcrop is of a swampy nature, owing to the low dip and the wearing away of the softer rock above. Between this station and Schoharie the formation is exposed at several points, and, where not exposed, its position is marked by a small ridge rising above the general level of the land. Schoharie; east side. To the east and northeast of Schoharie, running obliquely up the hill from the African church, is an almost continued exposure of this formation. This outcrop has been noted by Mr Darton, and it is said that most of the Coralline fossils of the William Gebhard collection were obtained from it. One fourth mile east of the postoffice at Schoharie, the shales underlying the Cobleskill are exposed by the roadside, and a few rods farther brings one to the old Brown quarry, at the base of which is exposed the Cobleskill, followed by what is evidently a cement rock nearly 5 feet thick. Above is a limestone in two layers of nearly equal thickness, their total thickness being 50 inches. They here form the roadbed and can be traced a hundred yards farther south to where Mr E. Vroman has recently opened Yroma quarry a quarry in them. These layers are worked as “ Coralline.” In- 860 NEW YORK STATE MUSEUM tercalated between them is a somewhat shaly layer with abundant corals. Schoharie creek sections. On the west side of Schoharie creek, besides the well known exposure south of the creek bridge, the Cobleskill is exposed at Clark’s cave, 14 mile north of the bridge. At this point the Lorraine shales are well shown, and the contact with the Salina shales can be seen. There is another exposure of the Cobleskill on the east side of West mountain, at the stronti- anite mine 1 mile north of Clark’s cave. Farther along on the northeast point of the mountain the rock is shaly, and collecting is good. Still farther along, nearly opposite Central Bridge, there is a similar exposure with fossils. From this point to Howes Cave there are no good exposures on the mountain side, and the dip soon brings it below the surface when a lower level is reached. Howes Cave. The Howes Cave section is well known, and from this point the formation is somewhat obscured for some distance to the north, but, at a point 1 mile below and % mile from the highway leading to Central Bridge, there is exposed in the creek bed the Cobleskill together with the Salina shales and the Lorraine beneath. This section is one of the best at which to observe the contact between the different formations. Beyond this station and nearly west of Central Bridge, on the farm of Mr Tarr, there occur very large boulders of Cobleskill arranged in nearly a straight line, from which corals may be had in large numbers. A mile and a half farther north from this point the limestone outcrops by the roadside at the house of Eugene Maxwell. The overlying rock has been removed by erosion, and considerable of the upper surface of the Cobleskill is exposed at this point, and on the read to Grovenor’s Corners, where frequent exposures are seen, specially near the house on the Judson Grovenor farm and at several points on the farm of Sol Dewey. Grovenor’s Corners. At Groyvenor’s Corners there is a fine ex- posure, and this outcrop continues at intervals for nearly a mile on the road to Carlisle. Carlisle. One mile northwest of Carlisle is the last good exposure of the Cobleskill on the way to Sharon Springs, but there are several points where its presence can be detected and ee ee ok 2a - a mp ee ier it i ne eb ee _—— —_ao-S le REPORT OF THE STATE PALEONTOLOGIST 1902 861 fossils obtained. But within 3 miles of Sharon Springs no ex- posures have been noted. Sharon Springs and Cherry Valley. At Sharon Springs and the section north of Cherry Valley it is clearly evident that there is no limestone between the Lorraine shales and the so called Salina shales above. Westward from Cherry Valley and extend- ing into Herkimer county the Salina shales rest directly on the Clinton formation showing that there can be no Niagara present in this section. 2 Altamont. In the Helderberg at Altamont, there is a space occupied by an impure limestone which may be referred to the Rondout. This limestone rests on the Lorraine shales. The same condition exists at the Indian Ladder. At South Bethlehem the Rondout is somewhat thicker and it is said would make cement. The contact with the Lorraine shales was seen at this point. A short distance south of New Salem there is a thin layer of sandstone lying on the Lorraine shales and below the Rondout. The sandstone contains iron pyrites, and Professor Prosser has provisionally referred it to the Clinton. It may now properly be included in the Rondout. Catskill. In the region southwest from Catskill are found the remains of corals and some brachiopods below the Rondout beds, and often the corals are directly on the Lorraine shales, which at this point appear to be conformable with the overlying rocks. South, near West Camp, at the end of a syncline extend- ing from the Catskill region, there is exposed in both limbs of the syncline, about 3 feet of the Wilbur limestone. At this station a number of Leptaena rhomboidalis were found. From West Camp south through Saugerties one can only hope to find the Cobleskill in the limbs of the anticline, which passes from some distance west of West Camp through Saugerties and finally into the Kingston region. The western limb of this syncline was not examined, but the eastern limb in the section about Saugerties is eroded, and only the higher formations can be seen. At Glasco there is a somewhat ob- scure outcrop, but farther south, beyond Lake Katrine and near East Kingston, there is a fine exposure. About 2 feet from the bottom there is a thin layer crowded with Atrypa reticularis. From this point the limb of the anticline is either obscured by the Champlain clays of the Hudson valley or eroded. At the Newark Lime and Cement Works the Wilbur is shown at several points. Several less important outcrops occur at Wilbur and Eddyville. Outcrops are also found across the Rondout creek opposite Wilbur. These relations hold good 862 NEW YORK STATE MUSEUM almost to Rosendale from Rondout along Rondout creek, but from Kingston through the Whiteport-Binnewater stations the cement lies on a floor of sandstone (Clinton). The cement at Rosendale is also on a base of sandstone, but at this point I have found small Leperditias in large numbers. They seem however to belong to the cement above. At High Falls there is a thin shaly layer above the sandstone and distinct from the cement beds above. This shaly layer con- tains an interesting fauna and seems to be equivalent to the Wilbur. It is to be noted that, throughout the cement region in Greene and Ulster counties, the cement beds above the Wilbur occur in two layers, between which is found the Cobleskill containing an abundance of corals, mostly Halysites. This limestone in the Whiteport-Rosendale region is about 12 feet thick as a rule. However, in the Newark works at Rondout this layer is only 7 inches thick. The faunal contents of this limestone in Ulster county have not been examined in detail but suggest some very interesting studies. The stratigraphy of Becraft mountain. Just east of the city of Hudson in Columbia county, is Becraft mountain, which has long been known as one of the interesting features in the Paleozoic geology of this State. The mountain is the only out- lier east of the Hudson river of the Helderberg series of for- mations, on which lie in proper succession other members of the Devonic series to and into the Onondaga limestone. It has been the subject of much study. Accounts and sections were given of it by Lieutenant Mather in his report on the first dis- trict of New York, and he then indicated the essential tectonic structure, which is that of a low syncline of the higher deposits resting unconformably on the upturned edges of the Hudson river slates. At a later date the structure of the mountain was more fully elaborated by Prof. W. M. Davis; and subsequently the writer specially studied an outcrop of the Oriskany sand- stone thereon of new interest in the composition of its fauna, and published a somewhat extended account of this element in the make-up of the hill [Museum memoir 3]. In all these various studies, however, it has been clear to the observers that we had not yet reached a true solution of the structure of the mountain as a whole. Evidence of faulting and displacement at the southeast end was recorded by Mather and reiterated by Davis, but it has not been clear how profound were these REPORT OF THE STATE PALEONTOLOGIST 1902 863 disturbances or how deeply they may have effected the rest of the mountain mass. For the most part, the mountain stands with abrupt sides in all directions except toward the southeast, being a wall of Manlius limestone underlain by the Hudson river shales. Such disturbances as it has undergone would be determinable with difficulty except by the aid of paleontologic facts. The interest pertaining to this area, the extensive series of exposures running through a number of highly fossiliferous deposits, the instructive illustrations which it affords of denuda- tion, folding, overthrust and displacements of various kinds and the easy accessibility of the locality have justified a more care- ful study of the area than has heretofore been made. This work has been specially facilitated by the fact that we have been able to plot the results on a topographic map of the area, prepared at the expense and under the personal direction of Dr John C. Smock, formerly assistant in charge of the State Museum, later, state geologist of New Jersey and now a resi- dént at Hudson. The areal work on this problem has been assigned to Prof. A. W. Grabau of Columbia University, who has this season spent some weeks on the ground and has arrived at a satisfactory analysis of the structure involved. According to his determinations, this proves to be much more complicated than had been supposed, and the succession of rocks and faunas there exhibited will, when properly displayed on the map, throw new light on the forces which were efficient in upturning the fossiliferous sediments of eastern New York. Dr Grabau’s work is essentially finished, and his results thereon will be found in another part of this report. The Westfield mastodon. In the month of June I was informed of the discovery of mastodon remains in the village of West- field, Chautauqua co. Such discoveries, though of frequent occurrence, are worthy in every case of investigation and record, and in this instance the situation was as follows. The bones were accidentally discovered while an excavation was being made on the property of Mrs Alice Peacock. The lot in which they were found to occur lies along the Nickel Plate Railroad, and is bounded on one side by the barn pertaining to the prop- erty and on the other by the highway. Across the highway is a low swampy area which extends for some distance to and S64 NEW YORK STATE MUSEUM beyond the railroad right of way. In digging over Mrs Pea- cock’s lot for the purpose of constructing a fish pond, bones were found lying on a pavement of heavy stones and just below a thin layer of muck. At the time of my visit on July 4 there had been taken from this excavation, one tusk, a number of ribs and vertebrae, part of the scapula, pelvis and sacrum. The ground had then been well dug over, and the prospect of finding other bones did not seem altogether favorable, nor had enough been secured to make the acquisition of them particularly de- sirable. It is quite probable however that more of the bones of this skeleton might be found by judicious excavation of the low land on the opposite side of the highway. Our attention is so often directed to the finding of mastodon bones in this State that [I have undertaken to bring together in another part of this report, simply as a matter of record, a list of such discoveries made, so far as records show, within the boundaries of the State. This list may be imperfect, but it is a significant one. There appear on it entries of about,60 different finds of this kind; and, while the most complete of the skeletons have been found in the swamps of Orange county, the record shows that the remains have been also pretty freely distributed throughout the western part of the State. I have pointed out there that these occurrences for the most part indi- cate that mastodons roamed the territory of New York prob- ably in such abundance as the buffalo roamed the western plains 40 years ago. It is not a matter of wonder that few complete skeletons are found, as these remains are located mostly close to the surface, and such parts as were left exposed — to the action of the air have naturally crumbled, while still other parts may have been destroyed by rodents or through other organic agencies. And it is also noted that the location of these bodies, not far from the surface and, in the vast ma- jority of cases, on swamps deposited on relatively recent river terraces or lake beaches, goes to indicate, that the interval of time separating the present from the day of the mastodon is not great; that these animals pertain to a late stage in post- glacial history and were doubtless contemporaneous with man, as is specially indicated by the Attica mastodon excavated by the writer in 1887. REPORT OF THE STATE PALEONTOLOGIST 1902 865 Other field work. Mr Richard F. Morgan has made for us some collections in the Marcellus limestone, temporarily ex- posed at Stony point south of Buffalo, at a time when such collections were much needed. Mr H. 8S. Mattimore has also collected to some extent in the Black river limestone in Jefferson county. Office work Memoir on the Guelph fauna in the State of New York. Ref- erence is made on a previous page to the field work done ‘during the past season with reference to these investigations. We have brought together in the memoir now in press a detailed account of this fauna, which, in New York, has risen to the very considerable representation of 70 species. It has been shown that this characteristic Guelph fauna, constituting vir- tually a new element in the Paleozoic limits of the State, entered from the west, penetrating as far east during the period of the deposition of the Niagaran dolomites as eastern Orleans county, and then retreated, reappearing after an interval in which some 30 to 40 feet of Niagaran dolomites had been deposited, and in the second invasion reaching as far east as the vicinity of Rochester. This second appearance of the fauna was less com- plete in species than the first, and its horizon lies at or very close to the summit of the dolomites, making thus a phenomenon pertaining to the closing stage of the dolomite episode. The little cluster of fossils of this fauna, which were reported as long ago as 1843 by Professor Hall from the Erie canal at Newark, Wayne co., a locality from which nothing more has ever been obtained, seems to have come from a still higher horizon within the basal deposits of the Salina shales, where, under unfavorable conditions, the impoverished representation of the Guelph fauna made its final appearance. The consideration of this fauna, which is illustrated by 21 quarto plates, involves the analysis and discussion of the nature of the sea and of the sediments of the Guelph period of time; and we have shown with reasonable conclusiveness that these deposits are ascrib- able to coral reef formations occurring in an inclosed and shal- lowing sea, which was gradually approaching the conditions essential for the free precipitation of salt and gypsum, such as prevailed during the succeeding Salina stage. The sea was one 866 NEW YORK STATE MUSEUM comparable in many respects to the present condition of the Red sea, receiving comparatively little fresh-water drainage with its exit to the ocean body constricted, and its shore lines dotted with coral reefs, on which flourished in immense pro- fusion a great variety of forms of invertebrate organic life. Memoir on the fauna of the Naples beds. In the 16th annual report of the state geologist, I published an account of the Cephalopoda of the Naples fauna, in which the great abund- ance of heretofore undescribed species was made known. Next in interest to the cephalopod element of this fauna come the lamellibranchs, and of these nearly 70 species are now described in the memoir in hand, together with such species of gastropod and other mollusca as appear in the fauna. _ This remarkable contribution of new facts is by no means the sole justification for the presentation of the Naples fauna. It is well recognized that this organic congeries, known as the fauna of Manticoceras intumescens, is one of the most persistent and widespread of the zones of organic life known in geologic history. Its affiliations with other manifesta- tions of this zone have been pointed out in a general way by the writer on other occasions, but this presentation affords the first opportunity for a close analysis of the elements of the fauna and their comparison with their manifestations in other countries. These investigations have led further to a clear con- ception of the conditions under which the fauna flourished and of its relations to contemporaneous faunas within the State of New York, so that we are now able to derive a definite idea of | the diversity of the geographic provinces which existed during Portage time. Of these we have frequently spoken, recognizing the fact that the Naples fauna or the western fauna of the Portage time was an invader from the west, but till now we have not seen clearly that this western or Naples fauna is itself divided into two geographic elements, one of which pene- trated farther east than the other. So that in Portage time we find that the eastern part of the State was occupied by a brackish or estuarine fauna represented by the Oneonta beds, the central region by the autochthonic Ithaca fauna derived from its immediate predecessor on the ground, the Hamilton fauna, while the western province, which we have termed the REPORT OF THE STATE PALEONTOLOGIST 1902 867 Genesee, occupied as a whole by the Naples fauna, was divisible into two subprovinces, the eastern or Naples and the western or Chautauqua. This memoir, it is hoped, will be printed during the current year and will be accompanied by about 20 quarto plates of illustration. } Catalogue of type specimens of Paleozoic fossils. A year ago I ‘announced that the compilation of this catalogue had been com- pleted and the printing begun. Printing has continued without interruption during the past year, and at the date of writing there are 650 pages completed. The work goes slowly, as it is one requiring great accuracy of treatment, but I hope to report the catalogue published before another year. With com- plete entries of all the type specimens now in our possession, the number of which constantly grows, the book will not fall far below 1000 pages and will include considerably over 5000 en- tries. Concurrent with the work of printing this catalogue, the labeling and ticketing of the types has been carried forward to correspond with the numbering in the catalogue itself. This has involved bringing most of our type specimens together in our rooms in the State Hall, though some part of them are left in their places in the exhibition collection in Geological Hall, because of the difficulty of replacing them with other specimens without disturbing the arrangement there. The work of arrang- ing the types has been largely in the hands of Mr Mattimore and has been carried out with much care. The crustaceans from the Salina (Pittsford) shales in Monroe county. In my first report I noted the fact that the museum had by purchase come into the possession of a unique collection of heretofore unknown fossils from a horizon at the base of the Salina shales, also unknown till that time. This is a thin layer of black shales made known by excavations in the Erie canal near Pittsford in the year 1897. So distinctive is the character of this formation and its fauna that we are distinguishing the layer by the term Pittsford shale. Mr C. J. Sarle, of Rochester, was the discoverer of the horizon and the fossils. When Mr Sarle’s collec- tion passed into the hands of the State, he was promised an oppor- tunity to publish with us an account of the peculiar eurypterid 868 NEW YORK STATE MUSEUM Crustacea contained in this fauna, and this very interesting publication is presented with this report. Mr Sarle has spent some weeks here, engaged under my direc- tion in prosecuting his studies, and the objects which he first brings to public notice will be esteemed of much interest to all students of these ancient and primitive crustaceans, specially the proposed new genus Hughmilleria, which is intermediate between the well known genera Eurypterus and Pterygotus. Two years ago the writer described some of the phyllocarid Crustacea from these Salina shales and one form of the strange genus Pseudoniscus, so that now the entire list of crustaceans from the shales is as follows: Emmelezoe decora Clarke Ceratiocaris (Limnocaris) praecedens Clarke Pseudoniscus roosevelti Clarke Eurypterus pittsfordensis Surle Hughmilleria socialis Sarle H. socialis var. robusta Sarle Pterygotus monroensis Sarle Publications During the past year the publications of the department have been two in number, Bulletins 49 and 52. The former contained various brief paleontologic papers as follows: Trenton Conglomerate of Rysedorph Hill and its Fauna, by Rudolf Ruedemann. Marcellus Limestones of Central and Western New York and their Fauna, by John M. Clarke. Marcellus Limestones of Lancaster, Erie co., by Elvira Wood. New Agelacrinites, by John M. Clarke. Amnigenia as an Indicator of Fresh Water Deposits during the Devonic of New York, Ireland and the Rhineland, by John M. Clarke. The latter comprised papers on the following topics: Contact Lines of Upper Siluric Formations on the Brockport and Medina Quadrangles, by J. M. Clarke, Rudolf Ruedemann and D. D. Luther. a he. ee!

The col- lections which had been made in the field during the survey of the Salamanca area were carefully studied and determined for use in the delineation of the formations on the map. These determinations were made in this office by Mr Charles Butts, who was occupied therewith during the early part of the year. Cooperation with the state engineer and surveyor. By an ar- rangement made with the state engineer and surveyor, we have been able to avail ourselves of the services of Gilbert van Ingen, formerly instructor in geology at Columbia University. Mr van Ingen gives one half of his time to the official named and the other half is given to duties connected with this office. He has therefore been engaged in prosecuting investigations which he had previously begun on the Potsdam sandstone and the fauna of the Beekmantown limestone. This arrangement is a tem- porary one, and we can not hope for its continuance after the expiration of April next. The areal and paleontologic maps of the Canandaigua and Naples quadrangles. In my last report I noted that these maps had been essentially completed, and that we have here endeavored to establish a more detailed subdivision of the formations than has before been attempted. During the past year these maps have been carefully revised and corrected, and some time was 870 NEW YORK STATE MUSEUM spent by D. D. Luther in the office on this work. They are now in the hands of the engraver, and it is hoped that they will soon be available. The fauna of the pyrite layer at the horizon of the Tully limestone. I reported last year that an investigation of this subject was under way, and I am gratified to be able to incorporate the results of this work in this report. The work has been carried forward at my suggestion by Dr F. B. Loomis, assistant pro- fessor of biology at Amherst College. Its interest lies in the fact that we have here to deal with conditions influencing or- ganic associations at the sea bottom, which can be interpreted only by actual experiment or from the most careful results of recent investigations on the varying conditions in existing bodies of salt water. Certain factors prevailing during Paleozoic time have brought about a segregation of iron sulfid in the sea water, which has deposited itself in an almost continuous sheet over a distance of 100 miles along the edge from Canandaigua lake to Lake Erie. With it are involved multitudes of organic remains, all of them of extraordinarily diminutive Size and yet, as Dr Loomis has shown, representing ar- rested and primitive phases of the profuse fauna which occu- pied the ground before these peculiar conditions set in. This important fact being determined, namely that the fossils are only modified stages or conditions of the organisms which pre- vailed in that sea, the theorem is to demonstrate the character of the sea which could produce such a deposit. It has been usual to regard black bituminous shales, which generally carry large quantities of such pyrite deposits, as indicative of shallow or foul waters where decomposition has gone on with so much freedom as to produce directly much carbonate of iron and thus indirectly the sulfid. It is not however certain that we are cor- rect in a conclusion of this kind, as recent studies of confined bodies of sea water, for example the Black sea, have indicated that separation of the sulfid is largely due to bacteria acting on the animal remains, but this is a process which takes place in the great depths where the bottom is covered with black mud, s0 that by comparison, such pyrite deposits, together with the black bituminous shales with which they are usually associated, REPORT OF THE STATE PALEONTOLOGIST 1902 871 indicate a greater rather than a lessened depth of the sea. It is an illustration of one of the constantly increasing instances in which the paleontologist must be armed for the proper inter- pretation of ancient physiography with the growing volume of facts derived from the study of existing conditions. Personnel of the staff The permanent staff of this department has been changed during the year only in consequence of the death of George B. Simpson, draftsman; slight alterations have been made in the title of two of the assistants. The staff is as follows: . R. Ruedemann, assistant state paleontologist D. D. Luther, field assistant George S. Barkentin, draftsman Philip Ast, lithographer Jacob Van Deloo, clerk H. S. Mattimore, preparator Martin Sheehy, machinist The following men have been temporarily engaged in the work of the department: Prof. Charles Butts, on the fossils of the Salamanca quadrangle; Prof. A. W. Grabau, on the survey of Becraft mountain; Gilbert van Ingen, on various special topics as above stated; C. A. Hartnagel, on the study of the Cobleskill limestone and its fauna; Myron L. Fuller and F. G. Clapp, of the United States Geo- logical Survey, in field work on the Elmira quadrangle. W.S. Barkentin, Ruth Holden and Mary M. Mitchell have also assisted with the work of illustration. Respectfully submitted JOHN M. CLARKE State Paleontologist Oct. 1, 1902 872 NEW YORK STATE MUSEUM PHILIP AST 1839-1903 With sincere sorrow I chronicle the death, May 8, 1903, of Philip Ast, who has been engaged in the work of this depart- ment for a period of more than 32 years. Mr Ast was of German birth and his early training was that of the Latin school and gymnasium of his home town in Bavaria. At the age of 16 he entered the Bavarian army and served as an officer therein in the War of 1866 between Prussia and Austria. In 1870 he came to America. Mr Ast had a keen artistic sense and remarkable calligraphic facility but in what was to be the work of his life he had had neither experience nor knowledge. On his arrival in New York he secured employ- ment with the well known lithographic establishment of Julius Bien & Co. and so successful were his first attempts there that when Prof. James Hall, needing a lithographer for the execu- tion of the plates of the Palaeontology of New York, applied to Mr Bien, Mr Ast was sent to Albany to take up this work though his experience was then of but a few weeks’ standing. Free from the usual crudities of inexperience his efforts were from the start successful and demonstrated not merely an apti- tude but a genius for the work. His activity in this career which has highly distinguished the illustrative work of this institution, began Ap. 1, 1871. The hundreds of lithographic plates of scientific objects executed by him remain as a record of his accomplishments, in the production of which he attained an adeptness and excellence which has never been elsewhere achieved in this country and few European workers have equaled his results for accuracy of delineation, perfection of finish and effect. His work raised the plates of the Palaeontology of New York to models of lithographic execution and exactitude. An artist on stone is at the mercy of the printer, and some- times a printer not over expert or none too conscientious has qualified the appearance of the imprints in a degree mortifying to the proper pride of the artist, but every lithographer comes to look with a sort of fatalistic toleration on such loss of the REPORT OF THE STATE PALEONTOLOGIST 1902 873 more delicate beauties of his achievement. It is right to say that these finer results of Mr Ast’s workmanship were never reproduced, were always sacrificed in some degree and their real beauties were known only to those who saw the stones before they left his hands. Mr Ast was a man of keen interests and intelligent apprecia- tions, kindly, true, loyal and generous. His life work was well done, and ended in his prime without a shade of departure from his standard. To such a servant, science in the State of New York owes no small debt. J. M.

THE DWARF FAUNA OF THE PYRITE LAYER AT THE HORIZON OF THE TULLY LIMESTONE IN WESTERN NEW YORK BY F. B. LOOMIS Plates 1-5 Recent determinations by the state paleontologist have shown that the Tully limestone which in central New York caps the Hamilton shales in its westward extension, feathers close to the east shore of Canandaigua lake, and from there westward to Lake Erie its place in the stratigraphic succession is marked by a thin sheet of pyrite from 1 to 4 inches in thickness. This pyrite deposit is often continuous for considerable distances, appearing in the strike at certain localities without break for a length of one to a few rods, and when interrupted it is only for a short interval. It may be looked on as an essentially continuous mantle, always maintaining its stratigraphic posi- tion between the calcareous Hamilton and the bituminous Gen- esee shales. It is a deposition synchronous with and in continu- ation of the Tully limestone in a region where that formation is - no longer represented by limestone sedimentation, where indeed bathymetric conditions did not permit the deposition of such a sediment. The highly bituminous deposits of the Genesee sea indicate befouled waters where organic decomposition was ex- tensively under way. The inception of these conditions is strongly expressed by the presence of the pyrite sheet 100 miles in extent on the strike; and in fact a similar indication is presented by the Tully limestone itself, which for some extent along its feather- ing edge carries considerable quantities of pyrite. The fauna of the Tully limestone is essentially a congeries of Hamilton species, but, added thereto, it contains the well known and far scattered brachiopod Hypothyris cuboides Sowerby, which has been called by Hall Rhynchonella venustula. For more than 50 years this species has been recognized as an index of early Upper Devonic time, and this diagnosis of its time value is supplemented by certain estab- lished mutations of earlier species. The Tully limestone thus represents the opening stage of Upper Devonic time in the New York succession. —_— REPORT OF THE STATE PALEONTOLOGIST 1902 893 The Tully pyrite contains a fauna so diminutive that it es- capes ordinary observation; so simple that it seems like a group of young forms; and so unlike the usual species of the limestone that without definite knowledge of its horizon it would be difficult to locate its stratigraphic position. Few of the specimens are over 2 mm in diameter, but are adults. The fauna is rich, including Crustacea, Cephalopoda, Lamellibranch- iata, Gastropoda, Brachiopoda, and Crinoidea; corals failing entirely. This fauna was first noticed by J. M. Clarke in 1885, who recorded 12 species, describing 11 of them as new; and sug- gested that there was abundant opportunity to enlarge the fauna. Two years ago, Dr Clarke placed some of the pyrite matrix from Canandaigua lake in my hands, and later. more from other localities. In all the regions represented by this material, life was abundant, a cubic inch of rock rarely furnish- ing less than two or three fossils; but, on account of the small size, they are difficult to find and more difficult to remove, as the matrix is extremely hard and tenacious.” So far as we have made it out, the fauna consists of 51 species, mostly less than 2 mm in diameter. These are distributed as follows: 40 from Canandaigua lake, 33 from the Livonia salt shaft (at a depth of 280 feet), 27 from Greigsville, 25 from Little Beard’s creek near Moscow, and 19 from near the Delaware, Lackawanna & Western Railroad at Moscow N. Y. The greater number from the first two localities is due partly to the fact that more rock from these was broken up, and partly because they are richer in specimens. The shells of most of the Brachio- poda have a distinctly Prehamilton appearance, doubtless due in some measure to their arrested condition of growth. Many of the gastropods and cephalopods have also such an aspect; but along with such shells are occasional larger representatives, _ 7U.S. Geol. Sur. Bul. 16. 1885. p. 28. * The only successful method devised for removing the fossils is to roast the pyrite some time over a blue flame, and then plunge in cold water. Without roasting, the matrix will not come away from the fossils, but breaks through them. After roasting, however, the pyrite cleaves away, and with a lens the tiny forms may be found. *‘Two more species were found, but lost in trying to prepare them more com- pletely for drawing. 894 -NEW YORK STATE MUSEUM which approach closer to the usual expression of the Hamilton species below, and from a gradation between the dwarfs and the normal Hamilton forms. As these species are unquestion- ably immediately descended from Hamilton ancestors, they are here considered as variations from the normal Hamilton species, and are described as mutations. This term is used not only in the common acceptance of the word, but within the meaning is incorporated the conception that the species have arisen under abnormal conditions. This seems to me preferable to calling them new species, though the variation is considerable in many cases. The resultant forms are such as might have arisen from a laboratory experiment. On considering the small size and the simple ornamentation of the specimens, the first suggestion is that they are young. But a whole fauna can not exist of im- mature forms alone. ‘There is further a uniformity in the size of the individuals of each species, which can only express adult growth. The Goniatites indicate this with clearness; here are over 100 representatives, all apparently of one species, each a per- fect miniature Goniatites with three whorls and 25 or more cham- bers, the whole no larger than the primitive three whorls of the normal species of Goniatites, from which they are evidently derived. The Brachiopoda specially show uniformity in the development of size; a valve with 10 or 11 ridges and furrows, with septum, muscular impressions and several lines of growth, will not be more than two or three times as large as the pro- tegulum of the same species from the Hamilton. The specimens are nevertheless essentially adults, so far as their relation to the congeries as a whole is concerned, though having usually only about one fifteenth the diameter of their progenitors. The fauna is not uniformly dwarfed, large specimens occa- sionally occuring among the otherwise tiny forms. Some groups of species are more affected than others. The dwarfing agent has totally eliminated the corals; the Brachiopoda are most uni- formly and extensively dwarfed; the Lamellibranchiata are much affected; the Gastropoda and Cephalopoda are mostly tiny, but also have some medium and occasionally large sized representa- tives, all adults. REPORT OF THE STATE PALEONTOLOGIST 1902 895 Such is the peculiar fauna, and in the study of it we are led to seek (1) the cause of this dwarfing, (2) the reason for the lack of uniformity of effect, (3) the length of time the fauna has been acted on by dwarfing agents, (4) the modifications effected both in shape and size. In considering whether water impregnated with iron and sulfur variously oxidized can dwarf without annihilating a - fauna, I may cite other instances of faunas similarly affected by the medium. ‘The oolitic hematite iron ore band of the Clin- ton beds extends from central New York westward to Wisconsin and south to Alabama, is at many localities highly fossiliferous, and according to Smyth! it was laid down in water carrying an excess of iron in solution. Observations made by the writer on the fossils of this layer obtained at Rochester N. Y. show that these species have an average of about one third the diam- eter of the same species in the beds just above and below. The dwarfing, in this case, can not be attributed to anything but the iron in the water, acting as an unfavorable environment. Linney’ notices the same dwarfing in this layer in Kentucky. To verify this dwarfing effect of iron in solution or suspension, experiments were made on small fishes, tadpoles and snails in aquarium water saturated with iron; and kept beside control aquariums, the fish, etc., in both cases being fed all they would take. After eight months in this iron water, the fish and tad- poles had lost from 3 mm to 5 mm in length.2 Their habits had also undergone considerable change.* It is well known that cer- tain species of fishes living in the freshened Baltic sea are much smaller than the same species in the Arctic ocean.® Herbst® and others, experimenting on embryos in water with various chem- icals, get dwarfed and abnormal results; these however have not lived on to adult condition. In all these cases, and in many 1Am. Jour. Sci. 1892. 143:487. » Report of Bath county, Ky. | *This experiment was carried on by Messrs Burrows, A. C.

The Cell. 1896. p. 323. 896 NEW YORK STATE MUSEUM others which might be cited, an unfavorable medium has caused dwarfing among the animals inhabiting it, and in the above instances the media have been modified by an unusual chemical change. Such was also the case in the sea in which the Tully pyrite was formed. It was a shallow water area, perhaps landlocked in a ’ measure and undoubtedly running shoreward into low coastal marshes. Its waters were surcharged with iron in solution, probably a ferrous carbonate; and over its bottom was a pro- fusion of decaying organic matter. Such decaying matter would give off sulfuretted hydrogen.| We have here two chemical agents at work, either separately or in combination, either of which would be an unfavorable element in the environment. There is very little if any distortion among these species. The dwarf condition may be attributed either to the presence of the iron, to the gases escaping from decomposition or to both. The pyrite is an insoluble compound and represents the precipitate formed by the iron and the gases of decomposition. The dwarf condition is coextensive with the deposit of iron. It is perhaps not surprising that these forms should be dwarf, but that they could live and retain their characters enough to make them recognizable while attaining only one fifteenth their normal! size, is noteworthy. The reaction which would deposit pyrite in such a sea is familiar. The iron, as ferrous carbonate, would unite with the sul- furetted hydrogen to form pyrite, carbonic dioxide gas and water (FeCO,+2(H,S)+O—FeS,+CO,+2(H,0O). There are probably | more steps in the process than the formula indicates, but the end results would be as stated. In the pyrite, as it has formed by precipitation, the fossils have been ingulfed, having died on the spot where they are found. This is evident from the fact that the bivalves when preserved, have both valves intact, which would not be so likely to occur if the shallow sea had been exposed to the play of the waves. The iron-carrying waters were not entirely disconnected from the purer waters of the sea without, for into these pyrite faunas come occasional representatives of 1Dr Dall tells me that ovcasionally after heavy rains HS is carried out into the waters along the coast of Florida, and that many animals are killed thereby, and others, which withstand the influence better, are distorted. , — nat nero en eTEaEy. ae a at ie eee Ata cary oe ’ a ® 1<—pere be, AE TERPTS, rhs a», REPORT OF THE STATE PALEONTOLOGIST 1902 897 the more actively moving groups of animals, such as snails and cephalopods. A sea answering all the above conditions could not be an open extensive body of water, like an ocean, but must rather have been more of the nature of a great swamp, with its open lagoons and connecting passages. This condition would in a measure account for the deposition of pyrite in disconnected but not widely separated areas. The animals in the iron-bearing lagoons would feel the dwarfing effect; those outside would be free from such conditions; and occasionally a normal individual might readily drift in among the dwarf faunas. The fossils in this collection represent three specific areas, one on Canandaigua lake, Ontario co., one about Livonia, Liv- ingston co., and one near Moscow, Genesee co. Of these, the first two seem to have been more isolated, the last has frequent larger forms which have drifted into it. In all the areas, how- ever, the degree of dwarfing is practically the same. In considering the relative time required to produce this dwarf fauna, or to deposit the pyrite layer, it is clear that the greatest dwarfing would be accomplished by the chemical action on the embryos; and it is equally evident that the life of several generations would be necessary to reduce a species to one fifteenth of its normal size. One might expect, that in the lowest parts of this deposit, the first generations which had lived in the iron water would be larger, and that those above would be successively smaller, as they had been exposed longer to the unfavorable conditions. This is not, however, the case. The animals from the bottom of the pyrite are of the same size as those from the upper part. There seemed to be fewer indi- viduals in the top than in the bottom part of the pyrite, but fossils were distributed all the way through. Hence it appears that the first embryos to be affected by the tron are as much af- fected as were the following generations which were descended from those dwarjs._ By the time these first dwarfs bred, they seem to have accustomed themselves to the abnormal environ- ment, so that their progeny grew as large as the parents. 1 This is a proposition which requires verification; but at present I know of no experiment which has been carried through several generations and observa- tion taken in regard to the growth under such unfavorable circumstances. 898 NEW YORK STATE MUSEUM The effect on the organisms is of two kinds, first the dwarfing, and second the modification in form. The amount of dwarfing varies in each group, apparently according to the habits of the group. Iron in solution in water tends to settle gradually to the bottom, as was found in experimenting on the fishes, ete. in the aquariums. Thus the bottom layers of water are denser and more impure. The forms living wholly on the bottom are thus most affected. Therefore it is not surprising to find that the brachiopods, which are either sessile or lie on the bottom, are the most dwarfed. There is also great uniformity in the size of the individuals of a given species, due to their spending their whole life in the iron water. No single brachiopod has been found which was larger than the natural adult size for. pyrite forms of that species. All the exceptions to the universal dwarfing occur in the other groups. The only period when the brachiopod is free swimming is during larval life; and, with the dwarfing beginning then and continuing all along, by the time the protegulum is formed, the animal is strikingly a pygmy. The adult brachiopods in the pyrite are seldom one fifteenth the diameter of the ancestral form. Lamellibranchs are aiso greatly modified, and show uniformity in size. One genus, Paracyclas, is uniformly one twenty-fifth the diameter normal to the species, and no larger individual has been observed. However, most of the lamellibranchs are only one fifth to one third the normal dimensions, and have thus for some unknown reason resisted the unfavorable environment better than the other groups. Their larvae are free swimming, and the adult moves about in a limited way, but they seem to have been brought up in the iron water. There are however no unusually large individuals or any which really approximate the size of normal adults in the Hamilton fauna. The lamellibranchs as a group are in a phylembryonic stage of development. It seems to be true in general that primitive members of a group have greater vitality in resisting unfavorable circumstances, and it may be that these forms are to be considered as primitive or ancestral. The gastropods and cephalopods possess, during their whole life, greater locomotive ability. Here there is a great variation in the size of the individuals of each species. Sometimes a form is one twenty-fifth the diameter of the ances- REPORT OF THE STATE PALEONTOLOGIST 1902 899 tral species; sometimes one fifth, and occasionally one half as large. This is due, I believe, to greater freedom of motion. Some individuals of these two groups are born and grow to maturity in this iron water. These are greatly dwarfed. Others come into the iron water later in life, and are less modified. Thus one species comes to be represented by various sizes of individuals. This variation in size is specially marked among the cephalopods. The trilobites are scarce, only two fragments being found and these together. They are not particularly modified, though small for an adult. The water seems to have been hostile to this class of animals. Ostracods however are not scarce, and are not particularly dwarfed. Corals are wholly wanting. As to the effects other than dwarfing, the brachiopods, having a well developed ornamentation, are best adapted to show such modification. The spirifers, with their rounded cardinal extremi- ties, their short hinge line, few and simple plications, resemble adult Prehamilton far more than Hamilton forms. In these characters also the pyrite specimens resemble young or embry- onic conditions. The goniatites, representatives of the genus Tornoceras, have an open umbilicus and a simpler suture line than their immediate Hamilton ancestors. In these respects they correspond to young Hamilton Tornocerata and represent a condition of arrested development. The shells of Tropi- doleptus from the pyrite are higher than wide, and with acute cardinal extremities, like young forms of T. carinatus, and again express an arrested condition. Several pyrite species find the correlative expression of their characters among adult forms antedating the Hamilton fauna. In other words, they resemble ancestral forms; and, inasmuch as the ancestral line of development closely parallels the development of the individual, one finds the forms with the appearance of youth, though adults in development. They are not forms arrested at any particular stage in their development; but all throughout their lives they have been retarded in growth; so that finally they have reached maturity, though with the bodies of youth. These full grown pygmies, when compared with the umbo of the ancestral Hamilton species, will find their correlate in one of the early stages of that norma] 900 NEW YORK STATE MUSEUM form. It is thus that the various species have been here deter- mined. However, when the area of the umbo which corresponds to the development of the pyrite form has been determined, it is noticeable that the pyrite form is strikingly smaller than the normal species at a corresponding stage. All of these fos- sils then represent cases of arrested development, with the understanding that the arrest is at no given point but all through the development. The Brachiopoda show the greatest modifi- cation; perhaps because they are the most specialized class and offer less resistance to the environment. The Cephalopoda, specially the goniatites, show modification in the next degree. Where they are dwarfed, they return to distinctly younger and more primitive appearing types. The Lamellibranchiata and Gastropoda, while often much dwarfed, vary but little in form from their Hamilton ancestors. This may be because they are less specialized groups. Under the unfavorable circumstances here presented, dwarfing is not the unusual but the ordinary phenomenon. In considering the descriptions of the various species in the pages to follow, one will observe the frequency with which pyrite forms resemble forms from the Marcellus shales. The Marcellus was another foul water sea; and this seems to represent a recurrence of conditions then existing. The pyrite sea is undoubtedly much more unfavorable to its animal life, but the modifications are in the same direction in enough cases to be noticeable, so that the question is raised, whether a variety of unfavorable conditions does not affect the forms in a similar manner. Herbst’s! experiments point in that direction, and these faunas also seem to do 80. A table, showing the species constituting this fauna and their distribution, is appended. Descriptions of species BRACHIOPODA Genus SPIRIFER Sowerby Of all the fossils in this group, the spirifers are the most abundant, most modified and the most instructive. Though found in so close association with a Hamilton fauna, not one 1 Loc. cit. REPORT OF THE STATE PALEONTOLOGIST 1902 901 has a Hamilton expression, but each form bears a close resemb- lance to an earlier representative of the genus. So striking is the resemblance, that one, shown the magnified drawings, might feel safe in pronouncing them to be from the fauna of the Onon- daga limestone. Assigning these to their ancestral Hamilton species has not been an altogether simple task, but has been car- ried out by comparing the pyrite forms with the beaks of the Hamilton species. These eight species of Spirifer, illustrate better than any other group the results arising from a life in an unfavorable medium. They are reversion types of the most pronounced kind. Spirifer fimbriatus Conrad, mut. simplicissimus nov. Plate 3, fig. 1, 2 The shell is almost circular in outline a trifle higher than broad. It measures 134 mm in breadth, 114 mm in length and 1% mm in thickness. The ventral valve has a wide, moderately deep median sinus and no lateral ridges. The dorsal valve has a short, broad fold reaching about half way to the beak. The cast shows the impress of a low, broad septum. The valves are only moder- ately convex. This form is equivalent to the simplest form of spirifer development, and comparable to S. fimbriatus arrested in its earliest stage. It is not the young of some other of the occurring species, as it is larger than S. fimbriatus mut. pygmaeus, and far simpler than any other species of its size. That S. fimbriatus should develop two mutations is not remarkable, considering the variation the species shows under normal circumstances. Localities.

The ventral valve has a wide sinus starting at the beak, and two low, wide folds on either side reaching about half way to the beak. The beak is small and 902 NEW YORK STATE MUSEUM acute. The dorsal valve has a short median fold and two lateral folds, none of which reaches more than half way to the beak. The septal impression is long and rather broad. Such a form resem- bles the S. raricosta Hall (Onondaga), but it is not so gib- bous, nor are the folds so strong. It is a simplification of S. fimbriatus, and about one twenty-fifth as large.

The ventral valve has a deep median sinus, and on either side five ridges, which reach about two thirds of the way to the beak. The median fold of the dorsal valve reaches a trifle over halfway to the beak, as do also the five lateral folds on each side. Near the blunt beak, the septum is deeply impressed. Thence a shallow groove runs along the middle of the median fold to the margin. The beaks are close, the ventral one overhanging the dorsal. Such a form suggests S. gregarius (Onondaga) in its younger forms. The re- semblance to the adult S. mucronatus is not striking, but the groove in the fold of the dorsal shell, the low area, and the similarity to the umbo of S. mucronatus, indicate that this mutation is a modification of the above species.

Plate 2, fig. 13-15 This is nearly circular in outline, the hinge line being very short, not over half the width of the shell; the cardinal extremi- ties are broadly rounded. An average specimen measures 114 mm in length, 144 mm in breadth and 3% to 1 mm in thickness. The gibbosity varies greatly. The ventral valve is strongly convex, with an elevated umbo, and a wide sinus from the beak to the margin. This last is bounded by rounded ridges. The small beak is incurved; the area is high, with a large pedicle opening. The dorsal valve is nearly flat, the beak only ‘slightly raised, and just a trace of a low, wide ridge near the margin corresponding to the sinus on the ventral valve. The mutation resembles A. umbonata in most points, but differs in that the sinus of the ventral valve is shallower and broader in the presence of the fold on the dorsal valve, and in being one tenth its diameter.

The surface is covered by 13 radiating plications, of which the middle one does not reach more than halfway to the beak. The ribs are scarcely as wide as the intervening furrows.

Otherwise the resemblance is close, except that the dwarf is about one tenth the size of a normal N. lirata. Localities. At the Livonia salt shaft and Greigsville. Total specimens 5. Nucula corbuliformis Hall, mut. pygmaea nov. Plate 1, fig. 10, 11 This form is an almost exact miniature of the normal N. cor- buliformis. The specimens are internal casts showing the impress of the teeth, pallial line, adductor muscles, and the small muscles in the umbonal region. A specimen measures 10 mm in length, 7144 mm in hight and 5 mm in thickness; this being about one half the normal size. Localities. At Canandaigua lake and at Livonia. Nucula varicosa Hall, mut. pygmaea nov. Plate 2, fig. 3, 4 The form is triangular ovate in outline, the anterior end be- ing abruptly rounded, the posterior almost truncate. The beaks are nearly at the anterior end and approach each other closely. The valves are strongly gibbous, their surface showing slight wrinkles, apparently indicating varices on the exterior of the shell. The teeth have left no impress on the cast. The type is 214 mm in length, 17/, mm in length and 1144 mm in thickness. They approximate N. varicosa closely except in size, being about one sixth the diameter. Localities. Moscow, near the Delaware, Lackawanna and Western Railroad and on Little Beard’s creek. Total speci- mens 2.

The spire is low; whorls ventricose, speci- ally the last one; aperture orbicular. There is considerable variability in the hight of the spire and the ventricosity of the last whorl; but all variations seem to grade into each other, 912 NEW YORK STATE MUSEUM and the ancestral form is also extremely variable. There is great variability in the size of the individuals, some being 3, mm in diameter, others as much as 10 mm; but all have the characteristic form.

Genus MACROCHILINA Bayle Macrochilina hebe Hall, mut. pygmaea nov. Plate 4, fig. 4 The form is conical, about twice as high as wide. The speci- men illustrated has four and one half complete whorls, the top being lost. The whorls are ventricose and the form slender. It measures as it stands 114 mm in hight and 1 mm in diameter. This resembles the slenderer forms as they occur in the shale There are two specimens of this species, from near the Dela: ware, Lackawanna and Western Railroad at Moscow. They are one fifteenth normal size. Macrochilina hamiltoniae Hall, mut. pygmaea Clarke Plate 4, fig. 1 This species presents a shorter cone, the hight being about half again as great as the diameter. The spire is short, having but three whorls, the last whorl being ventricose and making about three fourths of the full hight of the shell. The aper- ture is oval, higher than broad, acute above and obtuse below. The mutation is an almost exact miniature of the ancestral M. primaevus from the Schoharie grit. It measures 1144 mm in hight and 34 mm in diameter. It occurs at Canandaigua lake and the Livonia salt shaft. Total specimens 8. Genus PLEUROTOMARIA Defrance Pleurotomaria capillaria Conrad, mut. pygmaea nov. Plate 4, fig. 6 This species is represented by several fragmentary speci mens. It is a low cone, the whorls being ventricose and rounded. On the upper part of each whorl are three to four revolving grooves, separated by intervening carinae. The hight of an average shell is 5 mm, while the thickness is the REPORT OF THE STATE PALEONTOLOGIST 1902 913 same. The mouth of the shell is round, the hight and breadth being equal. This mutation is but moderately dwarfed and very little modified from the ancestral type. All the specimens came from Canandaigua lake and Livonia salt shaft. Total specimens 6. Pleurotemaria itys Hall, mut. pygmaea nov. Plate 4, fig. 5 These specimens are low cones about as high as broad, and consist of three whorls regularly expanding to the body whorl, which is ventricose. The aperture is about as high as broad and circular. The surface of the cast is smooth. The speci- men used for illustration is a small one. It measures 32 mm in hight and % in diameter. No matter how dwarfed they may be, the specimens retain the ancestral proportions very closely. There is considerable variation in the size of the individuals, from the size of the one illustrated to one half normal size. They occur at Canandaigua lake and the Livonia salt shaft.

Bul. 16.1885. p. 31 This tiny species has a needlelike form, tapering to a fine point. The upper surface is marked by regular undulations, 914 NEW YORK STATE MUSEUM which, toward the point, die out and leave the shell smooth. The figured specimen is 17% mm long and 14 mm in diameter at the thickest part. The undulations only cover the upper half of the shell. The form is about one half as large as the T. gracilistriata, and does not vary materially from that in shape or ornamentation. It occurs abundantly at the Livonia salt shaft. Total specimens 5. Tentaculites bellulus Hall(?), mut. stebos Clarke Plate 5, fig. 8 Orthoceras stebos Clarke. U.S. Geol. Sur. Bul. 16. 1885. p. 29 This is a larger and rarer form than the preceding. It is characterized by its surface being covered by narrow ribs, at some distance from each other, the intervals being about three times as great as the width of a rib. The specimens are merely fragments but show the size to be about the same as the normal T. bellulus. It is found only at the Livonia salt shaft, and probably represents individuals which have drifted into the pyrite waters. Total specimens 2. CEPHALOPODA Genus ORTHOCERAS Breyn Orthoceras subulatum Hall, mut. pygmaeum nov. Plate 5, fig. 6, 7 To distinguish between O. subulatum and O. con- strictum from the cast, and without the chamber of habita- tion, is impracticable; so what may represent two species is placed here under one head. The shells are smooth, with a cir- cular cross section, and an apical angle of 6° to 8°. The siphuncle is central or nearly so. Each chamber is about one third as high as its diameter. Most of the specimens are from 1 to 2 mm in diameter, but not infrequently larger individuals, up to 6 mm in diameter, occur. There is nothing other than size to distinguish the pyrite forms from the normal type. The appearance of these sporadic large forms, as explained in the introductory paragraphs, seems to be due to their having drifted from nonaffected areas into the iron saturated waters. This species occurs quite abundantly in all the localities. It is usually small at Canandaigua lake and Livonia salt shaft. At REPORT OF THE STATE PALEONTOLOGIST 1902 915 Greigsville it is rare, but at Moscow it is abundant, specially near the Delaware, Lackawanna and Western Railroad, where there is the greatest number of larger forms.

Bul. 16. 1885. p. 29 This tiny form is smooth on the surface, it is extremely slender, circular in section and tapers very slowly, 3° being its apical angle. The siphuncle is central and rather small, not deeply impressed on the cast. The length of a chamber. is about equal to the diameter. The pyrite form differs from its progenitor in being about one fifth to one fourth as large, and in the siphuncle being smaller in proportion. Otherwise the resemblance is striking, the great length of the chambers being the distinguishing feature. It measures '/, of a mm in diameter, and is very uniform in size. It occurs at Canan- daigua lake and Livonia salt shaft with fair abundance, and sparingly at Greigsville. Total specimens 25. Orthoceras nuntium Hall Plate 5, fig. 9 This species, characterized by its undulating surface, occurs at Canandaigua lake and Livonia, being scarcely dwarfed. It seems to occasionally have drifted into the foul iron waters, but not to have lived there; for not a single dwarf of the species came to light. Genus BacTRiTEs Sandberger Bactrites (sp.) mut. pygmaeus nov. Plate 4, fig. 12, 13 A single specimen consisting of three chambers in a fine state of preservation was found. The surface is smooth. The sec- tion is circular. Siphuncle close to the side, septa strongly oblique, apical angle 5°. The form is very like the species described as Orthoceras aptum, from the Marcellus Shales. It measures 2 mm in diameter and 4 mm in length. Found at Canandaigua lake. 916 NEW YORK STATE MUSEUM Bactrites (sp.) mut. parvus nov. Plate 5, fig. 4, 5 Two specimens, each about 244 mm in diameter, occur. The surface is smooth, section circular, ventral side marked by a moderately strong carina, septa slightly oblique, siphuncle un- known. This suggests strongly Orthoceras marcel- lum. Two specimens, one from Canandaigua lake, the other from Livonia salt shaft. (genus TORNOCERAS Hyatt Tornoceras uniangulare Conrad | Plate 5, fig. 3 This species is the one from which the mutation to follow has been derived. The specimens found in the pyrite are from one fourth to one. half the normal size, and appear like old individuals. The species is characterized by a depressed dis- coidal shell, closed umbilicus, smooth surface, thin septa, each with a prominent saddle on the inner side of the disk, a deep lateral lobe and a narrow, semielliptic ventral saddle. The pyrite specimens, though small, are similar to the normal type. They represent forms which have drifted into the pyrite- depositing waters. There are 6 specimens in all, from Canan- daigua lake, Livonia salt shaft and Moscow near the Delaware, Lackawanna and Western Railroad. Tornoceras uniangulare Conrad, mut. astarte Clarke Plate 5, fig. 1, 2 Goniatites astarte Clarke. U.S. Geol. Sur. Bul. 16. 1885. p. 29 This form occurs with greater frequency than any other in the pyrite. It appears in three distinct forms. The first is a gib- bous disk, whose thickness is to the diameter as 3 is to 7. The umbilicus is open and of moderate size. There are usually three whorls and no indication of the dwelling chamber. The section of a whorl is semielliptic, the inner side being deeply in- dented by the embraced inner whorl. The inner whorl reaches to about one half the hight of the surrounding one. In the younger whorls the indention is less. The outer shell is lacking, but on the cast are light swinging striae, indicating stronger striae on the outside of the shell. The septa are dis- REPORT OF THE STATE PALEONTOLOGIST 1902 917 tinct and swing forward to make a wide, shallow lateral saddle, then back, making a shallow lobe, and forward again, making a narrow ventral saddle. The two ends of the suture line do not meet, as the siphuncle intervenes. This variety has the suture line of T. uniangulare, but differs in the open umbilicus. It is also thicker in proportions. These are points possessed by a young T. uniangulare; but at the stage when the normal young has such a form, it has a much simpler suture line. This variety occurs most abundantly in all localities. ; A second variety is the more gibbous form, called by Clarke G. astarte. Its suture line has only a single lateral lobe and a shallow ventral saddle. There are usually two and one half whorls. The thickness is to the breadth as 1is to 2. These seem to be young forms of the above. The third variety is well marked off, in that it has a strong constriction on the outer whorl, a character which is seldom seen on the American Devonic Goniatites. All these forms occur at Canandaigua lake, Livonia salt shaft, Greigsville and Moscow, both at Little Beard’s creek and near the Delaware, Lackawanna and Western Railroad.

CRUSTACEA — Genus CRYPHAEUS Green Cryphaeus boothi var. calliteles Green Plate 5, fig. 15 Trilobite remains are extremely rare in the pyrite, two frag- ments representing all the individuals. The larger fragment includes a glabellum and the first body segments. This is a small individual, agreeing in every way with C. calliteles; showing even the nodes along the axial line of the body. The second fragment is an isolated eye of Dalmanites. They were found at Little Beard’s creek near Moscow and appear to be parts of a stray trilobite which wandered into the pyrite area to die. Inasmuch as the Ostracoda from the Hamilton have not been described, I have given those found specific names, as they are the representatives of an otherwise unknown fauna. 918 NEW YORK STATE MUSEUM Genus BEYRIcHIA McCoy Beyrichia dagon Clarke Plate 5, fig. 12-14 Beyrichia dagon Clarke.

Just in front of the middle on either side a broad valley goes from top to bottom. In this there rises a moderate node extending about halfway from top to bottom, and as high as the sheli outside the valley. The shells run very uniform in size, a typical one measuring 3 mm in length. 1 mm in hight and ~ mm in thickness. This form is common at the Livonia salt shaft, and occurs sparingly at Canandaigua lake and Moscow. Genus ENTOMIS Jones Entomis prosephina nov.

Near the front there are two concentric lines as for a beak. Just forward of the middle on each side is a deep sickle- shaped depression. The lower anterior end is drawn out and compressed into a plowlike, rounded projection. The measure- ments are, hight 7 mmm, length 144 mm and thickness 7% mm.

It is a more or less discontinuous deposit, appearing as lenses, each covering considerable area, but not over 1 foot in thickness. This pyrite contains a fauna of dwarfed forms, consisting of not less than 45 species. The sea is one whose waters were polluted with iron in solution, and by decaying vegetation. These two to- gether have made an unfavorable environment, which has dwarfed the forms inhabiting it, till they are on an average only one fifteenth the size of the same species in the normal and preceding Hamilton fauna. The iron in the water as ferrous carbonate, was probably precipitated by the sulfuretted hydrogen (FeOCO,+H,S—FeS+CO,+H,0) and thus formed pyrite. This impure water acted on several generations of animals, but the succeeding generations are no more dwarfed than the first which was subjected to the peculiar surroundings. In addition to the dwarfing the fauna is strongly modified in form, the species appearing in some cases like those of faunas still earlier than the Hamilton, and like young in all cases. This is an instance of arrested development, in which the brachiopods show the most modification. The species have been described as mutations of the various Hamilton species, though the varia- tion is greater than in many species, but the ancestry is evi- dent, and determined by comparison with the young of the ancestral species.

CLARKE; The effort has been made to render this list complete, though it is quite probable that finds have been made which have never been recorded, doubtless some which have not been recognized as mastodons. In most instances the bones have gone into-public and private museums, but some that have left the State may also have failed of record. | . We present a list of about 60 of these occurrences. It is of interest in more than one particular. Forty years ago the plains of the West and Southwest swarmed with immense herds of the buffalo, whose bones left on the ground have gone as _ completely as have their bodies. The dry air and arid soil have ‘reduced to dust millions of these skeletons. In the moist and cold climate of the postglacial East where the mastodon must have traversed New York in much the same abundance as the buffalo did the West, the watersoaked soil has preserved now and again a skeleton of this race. NoteveryMastodon americanus ended his days in a peat bog. It is to be noted that these occurrences, specially when con- siderable parts of the skeleton have been found, are in swamps and bogs of flood plains and beaches which, in the high water period succeeding the ice, were river bottoms. The fall of the water, with other conditions, reduced these bottoms to pools on which vegetation gradually encroached, but neither they them- selves, nor their contents can be of very ancient date. We may not safely deny the presence of the mastodon here during the early period of high water, but we may conclude that he remained to a comparatively recent date, when the floods had begun their retreat to their present confines. Worthy of notice also is the distribution of these skeletons. In two regions of the State they have proved specially numerous. Orange county leads as the home of mastodon remains, with a record of 24 skeletons. The lower Hudson valley counties, Sulli- van, Orange, Ulster and Greene afford 34 records. The region covered by Monroe, Ontario, Genesee, Livingston, Orleans and Wyoming counties records 14 skeletons. These two regions were 922 NEW YORK STATE MUSEUM the hunting grounds of the mastodon, possibly its breeding places. The series of Swamps in the long Appalachian valleys of Orange and adjoining: counties runs southward into New Jersey, and there the mastodon bones are also found with fre quency. Strangely, throughout the belt of territory between the Delaware river on the east and eastern Tompkins county on the west (virtually the meridian of Cayuga lake), a distance of about 100 miles, and thence north and south across the State, no single instance is shown by the record, of the presence of these remains. This can not be due to the fact that swamps and pools have not existed over this region, but must be ascribed to the gregarious habit of the animals and to the fact that some inducement brought them together in the other regions; probably more favor- able conditions for feeding and breeding. Western New York is a region of salt licks, but the central region is equally so, while the lower Hudson presents no such inducement. I insert here a page (492) from an article by F. A. Lucas of the National Museum, on the Restoration of Extinct Animals, pub- lished in the annual report of the Smithsonian Institution for 1900 and by courtesy of the secretary a copy of Gleeson’s draw- ing which accompanies Mr Lucas’s paper. The mastodon is an elephant, and his general appearance is indicated [in the accompanying drawing by J. M. Gleeson], but there are certain details some of which are purely deductive and some of which have fortunately been proved for us. The skeleton shows that, taking it as a whole, the mastodon and African ele phant represent two extremes of elephantine structures, the latter being the highest or longest legged, the former being for its bulk the lowest, most massive species known, although low is a com- parative term, for the animal attained a hight of 10 feet. Yet when the skull and teeth are considered, these two animals have decided points of resemblance. The skull of the African elephant is flatter than that of the Indian species; the skull of the mas- todon is even more depressed, and, as this feature would have shown plainly in life, it should be borne in mind in making any restorations. Many mastodon tusks have been found, and thus we know that they were slightly heavier, more abruptly tapering than in the mammoth or Indian elephant, and that, while there was great variety in the curve, in the typical examples from eastern North America they described nearly a half circle. In supplying the mastodon with a trunk it is to be borne in mind that there is a striking difference between the trunks of the Asiatic SNUBIIIIUG uopoysep i 93g REPORT OF THE STATE PALEONTOLOGIST 1902 923 and African elephants, that of the former wrinkling up when beut, as though it were equally elastic throughout, while that of the latter bends, as it were, in sections, suggesting the joints of a telescope. As the skull and teeth of the mastodon are simpler in structure than those of the Indian elephant, and in these par- ticulars more like the corresponding parts of the African ele phant, it is a fair inference that the trunk was similar and that it also lacked the fingerlike process of the Indian species. The northern mammoth was clad in hair and wool, and, as the mas- todon ranged well to the north, it is fair to suppose that the more northern individuals were more or less completely clad in hair. And this supposition is substantiated by the discovery noted by Rembrant Peale of long, coarse, woolly hair, in one of the swamps of Ulster county, N. Y. Thus the restoration of the mastodon represents a proportionately lower, more heavily built elephant than those now living, with recurved tusks and jointed trunk, and clad in fairly long hair.

Y.; Zool. 1842. pt 1, p. 108) Orange county 1790-1800 Montgomery Bones of the mastodon were found in 1790-91 and 1800 in the town of Montgomery about 12 miles from New- burg, Orange county. They were 10 feet below the sur- face, in a peat bog in marl. Several bones of the legs, some of the vertebrae, several ribs, and some of the bones of the head were obtained. . . “Eight similar skele tons have been discovered within eight or 10 miles of the neighboring country, and some of them were fifteen or twenty feet below the surface of the earth.” (8S. Mitch- ell. Medical Repository, New York. 1801. 4:212) All these specimens were discovered between 1790 and 1800. Some bones of these animals were found in 1782 3 miles south of Ward’s bridge in Montgomery, Orange county; another locality 1 mile east of the above bridge; another 3 miles east; another 7 miles northeast; another 7 miles east; another 5 miles westwardly from the same bridge; and another 10 miles north of the same bridge in the town of Shawangunk.

Three miles south of the village of Montgomery, on the farm now owned by Mr Foster Smith, the bones were visited by Gen. Washington and other officers of the army when encamped at Newburg, 1782-83. The Rev. Robert Annan, who then owned the farm, made a publication at the time, describing the bones, locality, etc., which caused Mr Peale subsequently to visit this county. Found about 5 miles west of the village of Montgomery, just east of the residence of Archibald Cranford esq. and near the line of the Cochecton turnpike. They were found about 7 miles northeast from Mont- gomery on or near the farm of Dr George Graham. THH PEALE SKELETONS 1 First found in 1799; further excavated 1801 by Charles Wilson Peale “in the vicinity of Newburgh.” The original bones “consisting of all the neck, most of - the vertebrae of the back, and some of the tail; most of the ribs, in greater part broken; both scapulae; both humeri, with the radii and ulnae; one femur; a tibia of one leg and a fibula of the other; some large fragments of the head; many of the fore and hind feet bones; the pelvis somewhat broken, and a large fragment, 5 feet long, of one tusk about midway.” He was therefore in want of the back and tail bones, some of the ribs, the under jaw, one whole tusk and part of the other, the breast bone, one thigh, and a tibia and fibula and many of the feet bones. Subsequent excavations added little. Rembrant Peale. The Mammoth. 1803 2 “Eleven miles distant from the former” (no. 1) Orange county. Found first in 1793. Excavated by ©. W. Peale. 1801.

Schaeffer, 3 miles west of Newburg, under muck and shell marl] lying on a stony pavement. The skeleton lacked 20 vertebrae, one scapula and all of legs and feet except- ing about 20 phalanges. It was restored and mounted and is now in the museum of the Brooklyn Institute. Monroe Found, for the most part, about 1888, on land of Martin Konnight. The bones lay beneath 8 feet of clayey muck at the bottom of a pond 3 to 10 feet deep. Further excavations were carried on in 1901 by J. M. Clarke. The bones found consist of rather more than one half the entire skeleton: two tusks, 8 to 9 feet in length, the two tusks of the lower jaw, scapula, tibia, femur, ribs, vertebrae, etc. They are in possession of the New York State Museum. .

This seems to me to be the same find recently described to me by Prof. W. B. Dwight who writes: “ The chief find of mastodon bones here occurred 40 or perhaps 45 years ago in a small circular pond(in an unusually dry season I believe) on what is called the Creek road, and from 2 to 3 miles northeasterly from the city. The bones were of large size and were, I think, put into the hands of a library associa- tion called the Lyceum. What became of them nobody knows.” A vertebra from Poughkeepsie is in the State Museum. 928 1705 NEW YORK STATE MUSEUM Columbia county Claverack This is about the date of discovery of. the first known bones of the American mastodon. They were found near the village of Claverack, and the first account of them is given in a letter from Governor Dudley to the Rev. Cotton Mather D.D., dated Roxbury, July 10, 17063 In this he states that a tooth with some other bones were brought to him by two “honest” Dutchmen of Albany who said that they were “taken up under the Bank of the Hudson’s River some miles below the city of Albany about fifty leagues from the sea.” Governor Dudley adds that a tooth of the same character was, the year before, ‘“ presented to My Lord Cornbury.” Lord Cornbury addressed to the secretary of the Royal Society, a letter dated New York 1713.2. This is as follows: I did, by the Virginia fleet, send you a Tooth, which, on the outside of the box, was called the tooth of a Giant, and I desired it might be given to Gresham College: I now send you some of his bones, and I am able to give you this account. The tooth I sent was found near the side of Hudson’s river, rolled down from a high bank by a Dutch country-fellow, about twenty miles on this side of Albany, and sold to one Van Bruggen for a gill of rum. Van Bruggen being a member of the Assembly, and com- ing down to New York to the Assembly, brought the tooth with him, and shew’d it to several people here. I was told of it, and sent for it to see, and ask’d if he would dispose of it; he said it was worth nothing, but if I had a mind to it, ’twas at my service. Thus I came by it. Some said ’twas the tooth of a human creature; others, of some beast or fish; but nobody could tell what beast or fish had such a tooth. I was of opinion it was the tooth of a giant, which gave me the curiosity to enquire farther. One Mr Abeel, Recorder of Albany, was then in town, so I directed him to send some person to dig near the place where the tooth was found; which he did, and that you may see the account he gives me of it, I send you the original letter he sent me; you must allow for the bad * In Eager’s History of Orange County; also quoted in Warren’s Mastodon giganteus, p. 198. * See C.

I desire these bones may be sent to the tooth, if you think fit. When I go up to Albany next, I intend to go to the place myself, to see if I can discover any thing more concerning the monstrous creature, for so I think I may call it. Mr Abeel’s letter runs thus: According to your Excellency’s order, I sent to Klav- erak to make a further discovery about the bones of that creature, where the great tooth of it was found. They have dug on the top of the bank where the tooth was roll’d down from, and they found, fifteen feet under- ground, the bones of a corpse that was thirty feet long, but was almost all decayed; so soon as they handled them they broke in pieces; they took up some of the firm pieces, aud sent them to me, and I have ordered them to be delivered to your Excellency. Dr Mather also addressed under date of Boston, Nov. 17, 1712, a communication to Dr Woodward on the same subject, and this was published in the Philosophical Transactions of the Royal Society in 1714 [29:62]; and he also, as does the publication just quoted, refers to two distinct localities, one, “ Claverack, about 30 miles on this side of Albany, New England,” the other, evidently that mentioned by Lord Cornbury, “as found 20 miles south of Albany on the bank of the river,” thus perhaps in the town of New Baltimore. Dr Mather inclines to the opinion of there having been, in the antediluvian world, giants, or men of very large and prodigious stature, by the bones and teeth of some large animals . . . which he judges to be human; particularly a tooth which was a very large grinder, weighing 4 pounds and 3 quarters, with a bone, supposed to be a thigh bone, 17 feet long. Albany county Coeymans Found on the farm of Mr Shear 4 or 5 miles west of the Hudson. Mather. Geol. First Dist. 1842. p. 44 Cohoes ~The eonditions under which this skeleton was found are unique. The greater part of it lay buried in the 930 NEW YORK STATE MUSEUM debris filling a great pothole in the Hudson river shales, exposed in digging the foundations for the Harmony (Mastodon) mills in Cohoes. This pothole was actually a double one, formed by breaking down the wall between two adjoining, and was the largest of many that lay above the flood plain of the present Mohawk river. Their origin was ascribed by Hall to the action of water flowing through crevasses in the glacial sheet. A portion of the skeleton referred to was found in a smaller pothole 60 feet away and 20 feet higher than the larger. After several thousand loads of muck with branches of trees had been removed, the first bones were found. Continued excava- tion exposed the major part of the skeleton, lying on a bed of clay, broken slate, gravel and waterworn pebbles and covered with vegetable soil. The gravel beneath was penetrated by rods to a depth of 10 feet without striking rock. Of the bones most of the larger were obtained, but many small ones were lost. Numerically reckoned, 84 bones were found, 189 were not. Professor Hall regarded this skeleton as derived from a carcass which had been frozen into the glacial ice and caught in these subglacial potholes; but, when we reckon the chances of a carcass being thus picked up by the ice sheet and of this chance carcass being caught in a pot- hole, we imply, either, that englacial carcasses were not infrequent or that the rock surfaces traversed by the ice were dotted with potholes. The latter proposition is not generally true, the former, judged by our knowledge of the mastodon, not probable. This carcass more probably belongs to the period of the swamps by which this pot- hole area was covered after the fall of the postglacial waters. This skeleton is of a relatively small animal and is mounted in the State Museum. Wayne county Macedon A few teeth in University of Rochester Museum. H. L.

In the last report of the state paleontologist the writer an- nounced the discovery of three different graptolite zones, ex- posed at the Deep kill in Rensselaer county, which represent the Phyllograptus-Tetragraptus shales of northern Europe and Canada. From their identification with the Point Levis shales of Canada and by correlation with the corresponding zones of Europe, they are placed in the lowest Lower Siluric, and con- sidered as representing the shaly development of the Beekman- town limestone and perhaps also of the Chazy limestone. The continuation of the investigation of the slates of Rensse- laer county has this year led, at Schaghticoke on the Hoosick river, to the finding of an outcrop of slates which contain a fauna known from the northeast of this continent and from Europe, and there considered as marking the closing stage of Cambric time. A very large quantity of excellently preserved material has been secured, the graptolitic part of which will be described in a forthcoming memoir. In this report, it is pro- posed to discuss only the geologic aspect of the discovery. Description of locality and beds The outcrop extends from the bridge of the Mechanicville- Johnsonville branch of the Fitchburg railroad, on both sides of the gorge for about one half mile. The river is forced, in this soqeys BUOUOAQOICT OIUquURD aoddy) Jo oansodxm “A *N 9YOOUYoRyo, ye AOA OISOOFT OY JO s][VJ JMO] I o01g REPORT OF THE STATE PALEONTOLOGIST 1902 935 distance, to plunge three times over precipices caused by the rocks in question and to form the waterfalls, a part of whose great water power is utilized now in the mills of Schaghticoke. The outcrop is totally isolated, there being an interruption of three quarters of a mile to the outcrops farther above the river, near the powder mills of Valley Falls, the interval being filled by drift. Likewise the Schaghticoke beds are separated by a drift-filled interval from the masses of shales and heavy banks of ‘‘ Hudson grit,” exposed a little farther down the river. There is no doubt that the latter mass, which contains graptolites of the upper half of the Lower Siluric, is separated from the beds at Schaghticoke by a great fault, probably the same which farther south, for instance at Rensselaer, separates the Cambric and Trenton shales. The Schaghticoke slates disappear also north and south of the river banks under great drift masses and do not reappear for considerable distances. It is however very probable or almost certain that they. represent a continuation of the belt of Cambric rocks (shales, slates, quartzite and limestones) which are well exposed on the hills east of Troy and have become well known by Ford’s discoveries of fossils. This belt has been traced and mapped by Walcott,! as extending as far as the Deep kill and been found by the writer to continue in fossilifer- ous beds still farther north, east and northeast of Melrose to within a few miles of the outcrop at Schaghticoke. As the lat- ter lies also in the direct strike of these Cambric beds, it is fairly to be concluded that it is a northward continuation of that belt. The Cambric beds of the slate belt of eastern New York have thus far furnished only fossils of the Lower Cambric or Georgian formation. The Dictyonema beds will, as we may anticipate, be shown to be equivalent to the highest Upper Cambric beds and may, hence, in a general way be said to represent part of the off-shore deposits of the Potsdam or Upper Cambric formation. The entire mass of rocks, exposed for about half a mile in the gorge of the Hoosic river at Schaghticoke, consists of very fine bedded, black and prevailing dull greenish to olive silicious and 1Am. Jour. Sci. 1888. v. 35, pl. 3. 936 NEW YORK STATE MUSEUM argillaceous slates with intercalations of thin limestone beds. The latter, consisting of hard gray, very fine grained limestone, are but about 1 inch thick and separated by black carbonaceous, argillaceous shales. These alternations of limestone bands and black, relatively soft shales, are well shown on plates 2 and 3. On plate 2 also the beds of green and black slates appear dis- tinctly by their different shades, and the thin bedding can be noticed. The whole terrane, which by the width of the outcrop might be taken to represent a considerable thickness, is appar- ently nothing but a manifold repetition of the same series of beds in small, closely packed, and in all conceivable ways dis- torted folds. The latter appear distinctly on plate 3, which shows a part of the north bank of the river. The lithologic similarity of the Schaghticoke beds with those of the Deep kill, containing the Beekmantown-Chazy fauna, is very striking; there occurring thin equally bedded, alternating, greenish and black slates and intercalated, thin, barren lime- stone bands. It is evident that there was no difference or break whatever in the physical conditions from the time of the depo- sition of these Cambric beds to that of the Lower Siluric beds; and the writer would not be surprised if in other localities they should be found to form a continuous series, as indeed is strongly suggested by the results of Professor Dale’s investiga- tion of the lithologie and stratigraphic characters of the slate belt. Inclosed in these shales there have been found two different kinds of fossiliferous beds. The one is characterized by the occurrence of Dictyonema flabelliforme HEichwald, the other by that of Clonograptus proximatus Mat- thew. Both faunules have been observed in several places of the outerop. This is partly due to a repetition of the same beds, but it is also obvious that neither of them is restricted to a single band, for one bed contained prevailing grown and half grown specimens of Dictyonema, while another bed, found a little farther down the river, carries nothing but the earliest growth stages. Likewise, at least two different beds, containing the Clonograptus faunule, have been noticed. On account of the extremely disturbed condition of the beds, I have not been able to satisfy myself as to the relative position ee a puv Woods pus spuvq ouoysouny, UIT oy} SMOYS 894B[S youlq AON OH YSRYo, yV soyvjs vurouodyoicy o1aquieg aoddy jo ainsod xny REPORT OF THE STATE PALEONTOLOGIST 1902 937 of these faunules, but, as a few specimens of Dictyonema flabelliforme _ have been obtained from the Clonograptus beds, it is provisionally assumed that the faunules belong together as parts of a larger fauna and do not indicate sharply separated horizons. The author and Mr van Ingen were not successful in determin- ing the interval of rock between the two principal fossil beds or the thickness of the series of strata. All that could be established was that in one place the bed with Clonograptus is connected with a series of alternating black and olive-green slates, the latter char- acterized by worm tubes, which series has a thickness of 15 feet; that in another place a Clonograptus bed, presumably the same, is found overlying a series of 20 feet of like slates, which alternate with two series of thin, barren limestone bands [see pl. 2, which shows the lower series of limestone bands]. The principal Dictyonema horizon occurs in a 114 inch band of peculiar lith- ologic character, it being a soft, strongly ocher-spotted black mud shale, which has a highly developed and, for the paleontologist, very unfortunate system of contraction joints. This band is sepa- rated by about 10 feet of black or greenish slates from a series of thin limestone bands in about the same number as that men- tioned in connection with the Clonograptus bed. It is, hence, to be assumed that these two series of limestone layers are iden- tical, and that the series of rocks containing these beds is at least 30 feet thick, but most probably considerably more. The fine black mud shale intercalated. between the thin limestone bands, contains in another place great numbers of early growth stages of Dictyonema. The principal Dietyonema stratum has been found to contain these fossils in such numbers that all surfaces of the thinly bedded band are entirely covered by colonies of Dictyonema fla- belliforme LEichwald, forma typica (=D. sociale Sal- ter) and var. acadicum. On a slab of similar lithologic character, lying loose on the bed, a valve of a Lingula or Lingu- . lella, not sufficient for identification, was observed. The Clonograptus bands contain: Protospongia sp. r Dictyonema flabelliforme Hichwald var. acadicum Matthew r 938 NEW YORK STATE MUSEUM Clonograptus proximatus Matthew (Staurograptus di- chotomus Emmons) ce Clonograptus cf. milesi Hall r Bryograptus lentus Matthew G B. spinosus Matthew G B. patens Matthew G Acrotreta bisecta Matthew r A. cf. belti (Davidson) Matthew r Notes on fossils The Protospongia occurs mostly in large spicules (or bundles of spicules), consisting of pyrite and limonite, the four branches measuring 10 mm and more. Walcott has figured spicules of smaller size but like form from the upper portion of the Olenel- lus zone in Washington county, N. Y., and pointed out their similarity with Prostospongia fenestrata Salter. Patches of sponge tissue have been found, composed of rhom- bic meshes of nearly half an inch wide and thereby reminding one of the gigantic form Palaeosaccus dawsoni Hinde, from the base of the Levis beds. As a large surface of the bed containing these sponges is accessible, a further exploitation of the same in another season will probably furnish sufficient material for an exact determination of the relation of this sponge to the form mentioned and to the ‘species described by Dawson from the Lower Levis beds at Little Metis. Dictyonema flabelliforme Eichwald. There is some variation in the expression of the forms, and some of the varieties which have been recognized in other localities may also be discernible here. The great majority of the specimens however are clearly identical with Dictyonema flabelliforme Eichwald, forma typica, as it has been described by Kjerulf and Brégger. This is evinced by the rather open long meshes and the thin, slender dissepiments. Quite a number of forms possess rather fine meshes and may be comparable to the variety conferta -Linnarsson.

We will not enter here on a description of the development of this species, nor on its interesting structure, but defer that part of the investigation to the description of the fauna. But it is here pertinent to point out that Emmons had evidently this form before him when he described his Staurograptus dichotomus. This species of Emmons has, ever since its publication, been con- sidered with some distrust as a somewhat dubious form; and this with some justification, for Staurograptus is, compared with other graptolites, an odd looking fossil. Staurograptus has been recognized again by Lapworth in the Cape Rosier (Quebec) zone [loc. cit. p. 168] and is referred to as the “‘ dubious genus Staurograptus of Emmons.” Gurley cites the genus in his list without any comment, evidently because he did not know what to make of the form. Our large material of Clonograptus proximatus, which contains all growth stages from the sicula upward, includes also Emmons’s Staurograptus in unmistakable specimens and in great number. The peculiar branching of this form, which produces a cross in the center, instead of the crossbar (funicle) of the other Dicho- graptidae is the surest means of its recognition. Emmons’s Staurograptus is but a very early growth stage of Clonogr. proximatus Matthew. Emmons found his specimens in “the black Taconic shales of Rensselaer county, N. Y.” There occurs in the Clonograptus bed still another species of Clonograptus which is readily distinguished by its very loose branching and the small number of branches. This form is closely related to, if not identical with, Graptolithus milesi Hall.2 The habit of both species is alike, and the thecae fail to show any differences; Clonograptus milesi has been found at Schaghticoke, though in much larger speci- * American Geology. 1855. 1:10°, pl. 1, fig. 21. * Geology of Vermont. 1861.

A differential character, however, which necessitates consideration lest hasty indentifi- cation might ensue, is the rapid twofold dichotomy in the Schaghticoke specimens, which, as in Clonograptus proximatus, leads to a crosswise branching in the center, while Clonograptus milesi possesses a “funicle” of considerable length. On the other hand, Clonogr. milesi is closely related to Clonograptus tenellus Linnarsson (sp.), a species which is found in Scania in beds intimately connected with the Dictyonema flabelliforme slate. In view of this relationship of Clonograptus milesi, it is important to note that that species does not belong to the Quebec group, as it is usually cited,t but was derived from the slates at Georgia Vt. Hall says in regard to the provenience of his material: The specimen from which the figures of this species were de- rived, is part of a boulder of Georgia slate, picked up in Monk- ton by Henry Miles of Monkton . . . The boulder was probably derived from the Georgia slate, either in Georgia or St Albans. This citation is evidently not to be understood as meaning that Clonograptus milesi is a form of the Georgian or Lower Cambric formation; but it may be concluded with a fair degree of certainty that it came from Cambric slates lying somewhere near the top of the Cambric formation, and it is possible that this occurrence indicates the presence of another subzone in the Upper Cambric. The discussion of the relations of the species of Bryograptus, cited in the list of the fossils of the Clonograptus bed, is reserved for the forthcoming description of the graptolite fauna of New York.

Our. specimen is also somewhat larger than the Cape Breton form. Acrotreta bisecta Matthew. There also occur types of an Acro- treta in the Clonograptus bed, the pedicle valve of which has been noticed only in a very much compressed state but still ex- hibiting the subcentric pedicle perforation. The brachial valve possesses the long, high, posteriorly enlarged (or dividing? in many specimens) median ridge, extending the entire length of the shell, and also on the cast, at least one pair of the minute pits, features which Matthew considered characteristic of his species Acrotreta bisecta, a form from the Dictyonema shales at McLeod brook, Cape Breton. As our form also agrees in general outline and dimensions with the Cape Breton species, it may well be considered as identical with the latter. Mat- thew has also recognized this species among the brachiopods collected in the Dictyonema shale at the Navy island, St John N. B. as the form which he had formerly described as Acro- treta baileyi. Acrotreta cf. belti (Davidson) Matthew. There occur small orbicular corneous brachiopod shells in the Clonograptus bed, which on account of their small size and compression offer con- siderable difficulty to a definite determination. The pedicle valve shows a small circular pedicle perforation, the brachial valve, which is well preserved, three narrow septa and pos- terior muscle impression, as one finds in Linnarssonia transversa Walcott. As the latter species has lately been reunited with Acrotreta by Walcott? this form is probably also referable to Acrotreta. It seems to us to be identical with the minute shells found by Matthew in the Dictyonema beds (divi- sion 3c) at Navy island, St John harbor, and doubtfully referred by him to the Lower Tremadoc form, Linnarssonia belti Davidson.* It agrees at least with this St John fossil in size, outline and horizon. The internal characters of the latter are not well known. * Nat. Hist. Soc. New Brunswick. Bul. 19. 1900. 4:275, pl. 5, fig. 5a-g. * Roy. Soc. Can. Proc. and I'rans. 1891. 9:43. * U.S. Nat. Mus.

A lucid discussion of the relations of the Upper Cambric to the Lower Siluric has there been fur- nished by Professor Brégger in his paper, “ Ueber die Verbrei- tung der Euloma-Niobe-Fauna (der Ceratopygenkalk fauna) in Europe.” Frech? has also discussed the problem of the upper limitation of the Cambric in an able and concise manner. We learn from these treatises that in Sweden, and still more in the Baltic provinces of Russia, the boundary between the Cambric and Siluric is most sharply defined; that there is a break in the deposition, and that an entire change of the faunal associations leaves little doubt as to the boundary line. In Norway, however, as Brégger has well shown in his “ Die siluri- schen Etagen 2 und 3 im Kristianiagebiet etc. 1882,” a gradual transition takes place between the beds assigned to the Cambric in Sweden and to the Lower Siluric Ceratopyge limestone. Here the boundary, as Brégger states, has to be drawn by “ charac- teristic peculiarities in faunistic features.” The same distin- guished author states [loc. cit. p. 79] in regard to the region of Christiania : It can not be denied, that in the beds below the Dictyograptus shale the fauna bears throughout a primordial (Cambric) char- acter; no graptolites, no cephalopods, no trilobites of the type of the characteristic Ordovicic genera (Asaphidae, Trinucleidae, Cheiruridae, etc., etc.). Immediately above the Dictyograptus shale itself we find simultaneously the first richer graptolite fauna (Bryograptus zone), the first Asaphidae (Symphy- surus incipiens Brégger) and soon also the first cephalo- pods (Orthoceras atavus_ Brdgger), in the Ceratopy- genkalk, in the region of Christiania and correspondingly also in the fauna of Hof, of the Shineton shales, etc. There seems then to remain only the possibility of placing the boundary at the Dictyograptus shale itself. I have hence united this with the Cambric. 1 Nyt. Mag. for Naturvidensk. 1896. B. 35, S. 164-240. 2 Lethaea Palaeozoica. 41897. 2: 30-34. REPORT OF THE STATE PALEONTOLOGIST 1902 943 It is further stated, that, while to some degree the Niobe- Euloma fauna has still a mixed character, and contains primor- dial forms (specially Olenidae), the typically developed fauna of the Ceratopyge shale and still more of the Ceratopyge limestone in Norway is in most prevailing degree a Lower Siluric fauna. Frech states that not a single species of trilobites goes beyond the Dictyonema shale into the Ceratopyge limestone in Sweden, in Norway Cyclognathus micropygus passes still into the Symphysurus bed, but not into the Ceratopyge shale; while, on the other hand, there appear not less than three new families and 13 genera above the Dictyonema bed. Therefore Brégger’s claim appears fully justified: The northern paleontologists, almost without exception, have always agreed to place the termination of the primordial fauna at the Dictyograptus slate; thus have done Linnarsson, Lind- strém, Nathorst, Tullberg, Holm, Lundgren, etc. in Sweden; that have I done similarly for Norway. If one therefore will use the term “ Cambrium ” for the pri- mordial-siluric sediments . . . then in my view one must also in England, Wales, France, Ameriea, etc., if this term shall be defined reasonably, put the upper limit of the Cambrium there where the second, to use Lapworth’s name, the Ordovicic fauna be- gins, 1. e. immediately above the Dictyograptus slate. The Cambric of the Baltic provinces of Russia has been thor- oughly investigated by Fr. Schmidt! It shows considerable modification from the typical development in southern Sweden. The black shales so characteristic in Scandinavia have thinned out, and soft and seemingly not very old deposits appear in their place. It is divided by Schmidt into three stages, (1) the Blue clay, (2) the Ungulite grit, and (3) the Dictyonema slates, which form the characteristic uppermost zone of the system. Of this it is said: This stage (3), the Dictyonema slate, is the highest member of our Cambrian series, and a very important one too, as it is the only indubitable connecting link between our Cambrian and that of Scandinavia. The Dictyonema slate has a thickness of from 1 to 10 feet and is exactly identical with the same stage as developed in Sweden and Norway. *Geol. Soc. Quar. Jour. Nov. 1882, p. 516; Acad. Imp. Sci. St Petersburg. Mém. 2. 1889. v.36. “944 NEW YORK STATE MUSEUM As its characteristic species is cited Dictyonema fla- belliforme KEichwald. In some places the Dictyonema slate shows also some other graptolites, which Schmidt believes to be identical with Bryograptus kjerulfi Lapworth. Also on the islands of Oeland (Moberg) and Bornholm (John- strup) the Dictyonema zone has been found, and in Belgium D. flabelliforme has long been known. It occurs there in the eastern part according to Malaise, and forms, as Dewalque asserts, as definite a horizon as it does in Wales and Scandinavia, in the lower part of the systéme salmien above the systeme revinien. The Dictyonema bed in Great Britain If we turn now to Great Britain, we find that there also the Dictyonema zone is well developed, in north and south Wales and in Shropshire, and that Dictyonema flabelli- forme has long been known as Dictyonema sociale Salter. But the zone is placed here at the base of the large mass of dark gray slates, to which Sedgwick gave the name Tremadoc slates, and which he inclosed in his Cambric system. The bitter controversy between Murchison and Sedgwick in- volved the position of this terrane, like that of the Lower Siluric terranes, in much uncertainty, but it appears that the consensus of the British geologists is now to consider the Tremadoc as a part of the Cambric and thus to place the Dictyonema shale at about the base of the Upper Cambric. This is clearly and ob- jectively expressed in Geikie’s Textbook of Geology, 1892, p. 729, where we read: It is at the top of the Tremadoc strata that the upper limit of the Cambrian or Primordial formations is now drawn in Britain . . . There appears to be more satisfactory proof of a distinct paleontological break at this stage of the geological record in Britain, or at least between the lower and upper part of the Tremadoc subgroup. This proceeding, which, as an incidental result, separates the Dictyonema slate from the accepted base line of the Lower Siluric by 1000 feet of strata, is at variance with the views of the continental geologists, as is shown clearest by the publica- tions of Professor Brégger and the new edition of the Lethaea Palaeozoica. It finds its explanation, besides the historic reasons, ~ REPORT OF THE STATE PALEONTOLOGIST 1902 945 in the fact that the relations of the Tremadoc to the Cambric, on account of the frequency of the Olenidae and Lingulellae in the former, are more striking than those of the Ceratopyge beds to the Olenus shales in Scandinavia. Professor Brégger’s careful revisions of the determinations of the English paleontologists [see his two works cited before] leave however little doubt, that, as Brégger concludes, the Tremadoc is to be correlated with the Ceratopyge beds, and hence the Dictyonema shale is to be regarded also in Britain as the terminal member of the Cambric series. The Dictyonema beds of the Malvern hills overlie the “ Dolgelly group” and are placed by Callaway! below the ‘“ Shineton shales”. The latter are considered by the same author as transitional between the Lingula flags and the lower Tremadoc, and thus still placed with the Cambric. Brégger, however, subjects the genera of the “ Shineton shales” to a revision? and thus finds the latter to be equivalent to a horizon between the Dictyonema bed of Norway and the Ceratopyge limestone, approximately to his 3 aa—d &%; thus transferring them into the Lower Siluric. The Tremadoc of north Wales has been worked out by Salter.’ Broégger concludes as to the Tremadoc of North Wales (in “ Ueber die Verbreitung etc.” p.42) that its largest part is equivalent to the Ceratopyge limestone horizons 3 aa—5 ar, that the lowest part of the Tremadoc (with Dictyonema flabel- liforme) corresponds already to his zone 2 e, the Dictyo- graptus slate of Christiania, while the uppermost part is per- haps equivalent to his 3 b, the Tetragraptus-Phyllograptus slate of Christiania. The Tremadoc beds of south Wales (St Davids and Ramsay island) have become known, specially by the investigations of H. Hicks.4 They differ considerably from the development in north Wales and in Norway, consisting of more than 1000 feet of gray, flaggy sandstones (St Davids) with few trilobites and *On a New Area of Upper Cambrian Rocks in South Shropshire, with a Description of a New Fauna, Geol.

In regard to these, Brégger disagrees with Hicks’s view of considering their fauna as closely allied to the Lingula flags, but holds that the species of Neseuretus and the lamellibranch fauna point to a younger age and indicate a shallow water facies of the deeper water deposits of the Tremadoc of north Wales, with which he correlates these beds. The latter would, then, also have to be transferred to the Lower Siluric. They are also underlain by the Dictyonema slates; which accordingly would also in Wales denote the upper boundary of the Cambric, instead of falling within the Cambric as held by Salter, Callaway and Hicks. Frech shares the views of the Scandinavian geologists as to the parallelization of the Scandinavian and British Cambrian- Silurian beds and holds with Broégger, that, though the relations of the English Tremadoc to the Cambric are more distinct than those of the Ceratopyge limestone to the Cambric on account of the prevalence of the Olenidae and Lingulellae, this fact is not of conclusive importance, as the Tremadoc is characterized, like the Ceratopyge limestone, by the appearance of those tri- lobite families which reach their principal development in the Lower Siluric. The Asaphidae, Lichadae and Ampycidae appear immediately above the Dictyonema slate; the Cheiruridae and Trinucleidae occur already in numerous representatives in the. Upper Tremadoc; while the Olenidae and Conocephalidae of the Cambric are represented only by genera, not pertaining to the Cambric proper, as Ceratopyge, Euloma, Remopleurides, etc. Frech concludes that no doubt can be entertained as to the Lower Siluric position of the Tremadoc terrane and adds that the confusion existing in England in regard to the boundary of Oambric and Siluric excludes a solution of the problem by recog- nizing the rights of historic priority. Professor Kayser also, in his Geol. Formationskunde, which has just appeared in a new edition (1902, p.48), holds that the Dictyonema bed forms the top of the Lingula shale and not the base of the Tremadoc shale, as the English geologists maintain, and further that the Tremadoc is a part of the Siluric formation ; that hence, also in England, the Dictyograptus bed closes the Cambric formation. REPORT OF THE STATE PALEONTOLOGIST 1902 947 In combining all the facts, viz that the underlying Dolgelly beds contain well known European and also eastern American Upper Cambric horizon markers, such as Peltura scara- baeoides, and the overlying Tremadoc terrane as distinctly Lower Siluric forms such as Calymmene blumen- bachii, while the graptolites, on account of their pelagic life, have a wide horizontal and very limited vertical distribution and are themselves extremely exact indicators of synchrony, we be- lieve it does not infringe on the rights of British geologists to ~ conclude that the Dictyonema flabelliforme zone is in Britain as in the rest of Europe to be held as marking the top of the Cambric series, wherever it is observed. The Dictyonema bed in North America The first to publish a notice on the occurrence of the Dictyo- nema bed in America was, so far as we know, Sir William Dawson! Sir William reports that Mr Richardson found at Matane “a bed of highly laminated black shale similar to that explored by Mr Weston a few years ago at Little White river, holding similar fossils in great abundance. Prominent among them is a beautiful Dictyonema, distinct from any of these found at Levis, and which on comparison with specimens presented to the museum by Prof. H. Alleyne Nicholson, appears so close in all its characters to D. sociale Salter, of the Eng- lish Tremadoe, that it may fairly be assumed to represent that species in our fauna. It is well known that some good paleon- tologists regard D. sociale as only varietally distinct from D. flabelliforme of Eichwald from Russia. . . We might infer from this that the Dictyonema beds at Matane may indicate a horizon somewhat lower than any of those at Levis. Associated with the Dictyonema are many specimens of Dichograptus (corrected in handwriting for Didymograp- tus) flexilis and D. logani, or an allied form, and there are also fragments of an undetermined Tetragraptus.’” * Peter Redpath Mus. of MacGill Univ. 2d Rep. Jan. 1883° p. 16. * We have no doubt that the species of Dichograptus cited here refer to the Cambric species of Clonograptus, either to C1. proximatus Matthew or Cl. milesi Hall, specially as also elsewhere these Cambric Clonograpti have been first compared with the Beekmantown Clono graptus Dichograptus) flexilis, 948 NEW YORK STATE MUSEUM It is added that in a neighboring bed there is a vast quantity of debris of trilobites, which seem to agree with the graptolites in indicating an Upper Cambric age, as they are apparently more nearly related to the trilobitic fauna of the Potsdam of Newfoundland, as described by Billings, than to that of Levis. Sir William Dawson’s conclusion of the presence of an Upper Cambric graptolite zone at the lower St Lawrence river has a few years later been verified by Prof. Charles Lapworth from material which had been submitted to him by the Cana- dian Survey. In his report! Lapworth recognizes three zones. namely, in descending order, the Griffin point or Marsouin river zone (zone of Coenograptus gracilis) which corre- sponds to the Normans kill beds*of New York, the Ste Anne zone (zone of Phyllograptus anna) which has been recognized in the middle of the three Deep kill graptolite zones, reported on in a former paper, and finally the Cape Rosier zone (zone of Dictyonema sociale and Bryograptus). It is the last zone which this year has been found fully rep- resented within the slate belt of eastern New York. We quote those remarks of Lapworth’s on this zone, which seem important to our inquiry. The oldest graptolitic zone represented is the Dictyo- nema sociale zone of Barrasois river (Cape Breton island) and of Cape Rosier, Gaspé. There are very few specific forms occurring in this zone, but they constitute together a very peculiar and distinct group, totally different from those of the remaining zones. The genera include Dictyonema, Bryograptus and Clonograptus, together with the dubious genus Staurograptus of Emmons. The Dictyonema appears to me to be absolutely identical with one of the forms referred by European (Scandinavian) geologists to Dictyonema flabel- liforme Eichwald, which is also, so far as our present evi- dence enables us to judge, identical with Dictyonema sociale Salter, from the Tremadoc of north Wales. To this zone belong the Barrasois river beds, those of Cape Rosier, of Little White river, of Grand Méchin point, of half a mile west of Long point, Matane, Little Capucin river, ete.

Roy. Soc. Can. Proc. and Trans. 1887. 4:167-84. REPORT OF THE STATE PALEONTOLOGIST 1902 949 In Europe, this zone (or zones) occurs in the Tremadoc of Wales and the Tremadoc and Ceratopyge beds of Norway {Brégger) and Sweden (Tullberg). It is Upper Cambrian (as British geologists receive the term), and is probably represented in the West by a part of the Calciferous series of New York and western Canada. It is distinctly older than the graptolitic mass of the Point Levis beds. Not one of its forms has hitherto been figured from the Quebec group. It may occur at Point Levis, if the Calciferous is represented there. This is a point for future discovery to settle. In the meantime, however, it will be better to refer to the zone as the “ Cape Rosier zone.” Like the Levis Calciferous conglomerate beds, its fauna is made up of genera, partly Cambrian and partly Ordovician (i. e. partly Primordial and partly Cambro-Silurian). The Cambrian age of the Dictyonema-bearing Barrasois river beds of Cape Breton island is demonstrated by their included Olenidae. The Dictyonema beds of Gaspé and Méchin can_not be far above this Cape Breton zone. It is exceedingly probable, therefore, that, as in Cape Breton, the Dictyonema beds lie not far removed from the unconformable base of the fossil-bearing rocks of the district. From further statements of the same author it can be con- cluded that he was averse to paralleling definitely the Cape Rozier zone with any formation of the New York series; for instance, in the summing up on page 174, we find under Cam- bric formations: B! Fine conglomerates . . . and black slates (of Shick- shock range). B? Gray, red, brown and black shales with beds and bands of dolomite (Localities: Les Islets, coast south of Cape Rosier, etc). Fossils: Dictyonema, Bryograptus, etc. To this is added (B! and B? may, perhaps, represent both the Upper Potsdam and the Calciferous rocks of the western district of New York and central and upper Canada.) In the table on page 183, the zone has been divided into two subzones, as follows: B Dictyonema sociale zone (A). Shales of Cape Rosier, Little Whale river, Grand Méchin point, with Bryo- graptus sp., Staurograptus, Clonograptus, Dictyonema sociale Salt. Dictyonema zone (B). Shales of Barrasois river, Cape Breton island, with Dictyonema sociale Salter, and Olenidae. Dr Matthew’s untiring and. enthusiastic geologic investiga- tions have later on led to the discovery of the Dictyonema zone 950 NEW YORK STATE MUSEUM in the beds of the St John basin in New Brunswick! Mr Mat- thew had, in full appreciation of the importance of D. fla- belliforme for the determination of the upper boundary of the Cambric system, searched for years for this fossil in the black shales of division 3 (Bretonian) till the desired fauna was found on Navy island in St John harbor. _ We learn from his important publications the interesting fact that in the St John basin, Dictyonema flabelli- forme is not restricted to a single zone above the trilobite zone characterized by Peltura scarabaeoides, but that this Upper Olenus fauna extends in the Canadian Cambric into the Dictyonema zone, since its trilobites occur in lentils with layers included in shales which contain the Dictyonema. Mat- thew’s practice has been to “ regard the beds above the horizon to which these trilobites, so far as known, are limited, to be the true zone of Dictyonema, corresponding to the beds so desig- | nated in Europe, and to include the beds below, in which Lepto- plastus, Sphaerophthalmus and Peltura are found, and which also contain Dictyonema, as a lower zone corresponding to the upper part of the Upper Olenus zone as developed in Wales and Scandinavia.” He obtains thus the following zones of the Bretonian division of his St John group: a Zone of Parabolina spinulosa b Zone of Peltura scarabaeoides, contains also Dictyonema flabelliforme c¢ Zone of Dictyonema flabelliforme, typical development of the species This is followed by an interruption of several hundred feet, the fauna of which is not known, and then by the Lower Siluric Phyllograptus shales. These results obtained in the St John basin are important in several regards: they prove that D ict yonema flabelli- forme is not everywhere restricted to a single graptolite hori- zon, but may range through a considerable thickness, and that its beginning falls distinctly into the hemera of the last trilobites * See On a New Horizon in the St John Group, in Canadian Record of Science, October 1891, p. 339-43, and Two New Cambrian Graptolites with Notes on other Species of Graptolitidae of that Age, in N.

There can hence be no doubt that even where the Dictyonema zone contains no characteristic fossils of the Upper Cambric beds, it should be united with the latter and not with the succeeding graptolite faunas of the Lower Siluric. Lately! Dr Matthew has also described the Dictyonema zone as overlying the Peltura zone from Cape Breton island. Dr Ells’s exhaustive Report on the Geology of a portion of the Province of Quebec? and the appended list of fossils by Dr Ami? prove that in the classicai region of Logan’s Quebec group the Dictyonema bed has not yet been observed. In citing Lap- worth’s correlation of the Dictyonema zone, and remarks (p. 48k) Dictyonema sociale zone is mentioned as “ presum- ably Cambrian,” and it is added “that Dictyonema has not, in so far as is yet known, been figured from the Point Lévis beds, the most westerly point from which it is reported being Matane.” Dr Ells is however inclined to doubt the correctness of Lap- worth’s correlation of the Dictyonema zone, and remarks (p. 48k) that Lapworth considers the Dictyonema zone from the presence of three species to belong to a lower formation than the Cambro- Siluric, and that of these two, a Clonograptus and a Dicho- graptus are apparently new and therefore not conclusive. The presence of Dictyonema appears, then, to be the only reason why those portions in which this form is known to occur, otherwise intimately associated with strata holding Cambre- Silurian fossils, and which have so long been regarded as be- longing to that group, should be removed from their apparently proper position in the series and placed in a different geological system; and, in view of the wide range Dictyonema is known to possess, we may well hesitate before deciding on such a separa- tion, unless confirmatory stratigraphical evidence can be pre- sented. While this conservatism at the time of the publication of the report was justified to some extent, the facts brought out by Matthews’s and Broégger’s investigations serve to dispel all 1 Roy. Soc.

On the south shore of the St Lawrence, below Levis and also on the south shore of the island of Orleans, beds of conglomerate occur at about this horizon, in which the Lower Cambrian fauna occurs (Olenellus thompsoni). 3 Bright red shales, with thin bands of greenish and gray shale. 4 Red, greenish gray and black shales, with interstratified sandstones (Upper Sillery). Obolella pretiosa occurs in the upper part, near Sillery, and on the south side of the river Obolella pretiosa, Protospongia fenestrata, Phyllograptus typus, Tetragraptus serra and Lingula quebecensis. 5 Levis shales and conglomerates of Point Levis (Calcif- erous). 6 Black and grayish striped or banded shales, ete.

In regard to a correlation of the Cape Rosier or Dictyonema zone of the Lower St Lawrence shore, we find in Dr Ells’s report (p. 82k) the following statement: From Métis to Cape Rosier the great bulk of the rocks belongs to the Sillery formation and much of it to the lower portion of that division, and entirely below what we regard as the fossiliferous or graptolitic Lévis formation of the city of Lévis and the southwest end of the island of Orleans. The rocks of Cape Rosier, in which the Dictyonema sociale, Clonograptus, etc., were found, as well as those 2 miles below Great Matane river, where similar forms occur, represent divisions 2 and 3 of the Cape Rouge section and the Beaumont shore, as well as of the strata on the south side of the island of Orleans, consisting of black, green and gray Shales, with some red beds, together with the gray limestones and hard, grayish quartzites, while the associated limestone conglomerates are like those seen at Beaumont and at the east REPORT OF THE STATE PALEONTOLOGIST 1902 953 end of the Island of Orleans. This character is maintained with great uniformity for the entire distance west of Marsouin, though at certain points the Sillery sandstones and red and green shales representing division 4 are more highly developed than at others. The rocks of this section would, therefore, both on the evidence of Professor Lapworth from the fossils, and from the comparison with the stratigraphical sequence of the Cape Rouge rocks, belong to a portion of the Cambrian system, probably representing the upper and middle divisions of that system, while the overlying Levis graptolitic shales and lime- stone conglomerates would represent the lower portion of the Ordovician or Cambro-Silurian system. Dr Ells refers thus, on the evidence afforded by the strati- graphy and the graptolites, determined by Lapworth, the Sillery rocks (divisions 1, 2, 3 and 4) to the Cambric, and the Levis beds (division 5) to the lower Beekmantown. Mr Walcott, in his review of Dr R. W. Ells’s report? takes exception to some of Dr Ells’s conclusions, as we see from his quoted statements: The Cape Rosier Dictyonema sociale zone is regarded as the lowest of the graptolitic zones, and to indicate the horizon of the Tremadoc terrane of Great Britain. The Cape Rosier beds are referred to the Upper Cambrian by Professor Lapworth and Dr Ells, but, with our present knowledge of the Cambrian in America, I would refer them to the Lower Ordovician or to the lower Calciferous. The occurrence of the typical Calciferous fauna within one hundred (100) feet of the base of the Levis series, at St Joseph de Levis, points very strongly to considering the graptolitic fauna of the Upper Sillery to be of Calciferous age, if a comparison is made with the Phillipsburgh section. Dr Ells refers the Sillery series to the Cambric, and in this I mainly agree with him, except that the upper portion is evi- dently a passage series between the Cambric and Lower Siluric. On lithologic and stratigraphic evidence the line would be drawn at the summit of the red shales. On paleontologic evi- dence, as furnished by the graptolites, I would include the upper portion of the Sillery red and green beds in the Lower Siluric, as I think they are above the typical Potsdam zone of America. While we agree with this distinguished author in referring the upper part of division 4, containing Phyllograptus 7 Am. Jour. Sei. ser. 3. 1890. 39:113. 954 ' NEW YORK STATE MUSEUM typus and Tetragraptus serra, to the Beekmantown, the Cape Rosier Dictyonema sociale zone should, in our opinion, on the evidence adduced above from northern Europe and specially in view of the fact that in the St John basin it is found in the same beds with Cambrie trilobites, be retained in the Cambric system. Dr Ells correlated this zone with divisions 2 and 3; as division 2 however contains Lower Cambric fossils, the Dictyonema zone should be expected at a much higher level, and we surmise that, if it is ever found in the Quebec region or Cape Rouge section, it will appear in the lower or middle part of division 4, or just below the line, where Walcott would terminate the Cambric system. We have already stated in the report on the Levis beds of the slate belt that Professor Dale! recognized the presence of a terrane (horizon F) of ca, 35 feet of “ gray, calcareous or very quartzose, finely bedded shales or black shales, with thin lime- stone beds’’, which he referred to the Beekmantown. Dr Gurley identified in the suite of fossils submitted to him for this ter- rane, Bryograptus, Dichograptus, Callograptus salteri? ef. bendrograptus sp. and Dictyonema flabelli- forme. In regard to this fauna it is said: “ Several of these are regarded as probably of Calciferous age, which would place the horizon in the lowest part of the Ordovician. The European species of Bryograptus come from the Upper Cambrian. Dictyonema ranges from the Ordovician into the Devonian.” The cited list of determinations gives us the impression that Gurley had before him fragmentary representatives of both the Cambric Dictyonema and Lower Siluric Phyllograptus zones. There is no doubt that, with his thorough knowledge of the graptolites, Dr Gurley would not have failed to recognize the zones mentioned, if such complete collections as the writer has, had been at his disposal. But any one who is at all acquainted with the slate region of Vermont and eastern New York, knows the extreme difficulty of securing anything but fragmentary col- lections in the intricately folded and mostly strongly cleaved beds. Exceptionally fortunate circumstances are necessary to permit the collection of superior material. U.S. Geol. Sur. 19th An. Rep’t 1899. p. 185. REPORT OF THE STATE PALEONTOLOGIST 1902 955 The fact, that the Upper Cambric Dictyonema and the Lower Siluric Phyllograptus zones have apparently been united by Dale in his horizon F, demonstrates the lithologic identity of the beds, also observed by the writer and suggests, as stated before, the continuation of the same physical conditions from the Upper Cambric into the Lower Siluric time. Possible subzones of the Dictyonema horizon Whether the Dictyonema bed of New York will ever admit a further division into subzones, we are at present unable to sur- mise. In Norway Brégger has found that the mut. norvegica lies a little higher than the typical Dictyonema flabelli- forme. In Sweden, Linnarsson, in 1871, had already discerned a zone with Clonograptus tenellus Linn.,, which was at first thought to lie below the Dictyonema flabelliforme zone, and to be associated with the Cam- bric trilobite Sphaerophthalmus alatus. Moberg! has, however, shown that this form lies above Dictyonema flabelliforme, and that the latter species occurs in layers immediately adjoining those with Sphaerophthal- mus alatus. Not very long ago Anton Nilsson and Axel Tellander? demon- strated that also in southern Sweden (near Fogelsang, Lund sheet) several zones can be discerned, namely, in descending order : Zone with Dictyograptus norvegicus Kjerulf and Bryograptus kjerulfi Lapw. Zone with Clonograptus ef. flexilis Hall. Zone with Dictyograptus flabelliformis Eichw. forma typica. Their observations verify Broégger’s statement of the occur- renee of Dictyonema flabelliforme var. norve- gicum and of Bryograptus kjerulfi above the typical Dictyonema flabelliforme. Matthew’s results did not suggest to him a possible separa- tion into a Clonograptus and Dictyonema zone. At Schaghti- coke the two occur separated, but it is impossible to Say posi- et ana ' Sver.

The occurrence of still another Clono- graptus, Cl. milesi Hall, in black shales near Georgia Vt., indicates however that there may be Cambric subzones, charac- terized by forms of Dictyonema and the two species of Clono- graptus. These subzones may lead very gradually into the Tetragraptus and Phyllograptus zones of Beekmantown age; for the occur- rence of a Clonograptus cf. flexilis Hall (a Point Levis form) between the two Dictyonema horizons reported by Nilsson and Tellander and the finding of a typical specimen of Bryograptus kjerulfi in the Tetragraptus shale of the Deep kill by the writer, as well as some other facts of dis- tribution, would indicate the presence of such transitional zones between the Dictyonema and Tetragraptus beds. These would be equivalent to the Ceratopyge beds of Scandinavia, which there intervene between these graptolite beds, and to the Tre- madoe of Britain. Bearing of the occurrence of the Dictyonema bed on Cambric paleogeography , Messrs Ulrich and Schuchert have undertaken the task of elaborating a theory in explanation of the differences in stratigraphic succession and faunistic aspect of the Appala- chian region and the area to the west of the same during paleo- zoic time. The solution is found in the assumption of the pres- ence of one, or at times, two parallel basins, separated by and inclosed in folds or barriers, and extending during the greater part of the Paleozoic over the territory of the present system of Appalachian folds. This theory not only serves to clarify a multitude of well known stratigraphic and paleontologic facts, but is also an incentive to investigations in further elaboration or modification of its details. The facts presented in this paper furnish, on one hand, a new argument for the presence of such basin, and, on the other, appear to necessitate a modification in regard to the fixation of the date at which one of them, the Levis basin, is supposed to have originated. 1 Paleozoic Seas and Barriers in Eastern North America. N. Y. State Paleon- tologist. An. Rep’t.-. 1901. p. 633-63. EE ———— REPORT OF THE STATE PALEONTOLOGIST 1902 957 We have seen that the Dictyonema fauna is an undoubted Atlantic fauna. In North America it has been recognized in the St John basin of New Brunswick, on Cape Breton island and at several places on the south shore of the St Lawrence from Cape Rosier to Matane river. It has now been found as far south as Rensselaer county in New York and probably ex- tends through the slate belt of New York and Vermont. It is hence, with the exception of the Levis region, where it has not ™ yet been found, about coextensive with the present known ter- ritory of the Phyllograptus fauna. Like the latter, it has not been found either east or west of this long belt and is therefore to be assumed” to have entered from the Atlantic, a basin of similar configuration and extension as the Levis channel, in which the Atlantic waters deposited the Phyllograptus fauna. The Dictyonema shale is now however of Upper Cambric age, of which it represents the closing period wherever it has been found. It stands, lithologically and faunistically, in the same relation to the upper Potsdam of the Champlain region as the later Phyllograptus shales to either the Beekmantown beds, with which the writer correlated them, or to the Chazy beds, with which they are equivalent according to Ulrich and Schuchert’s views. The Dictyonema beds represent, like the Phyllograptus shale, the graptolite shale facies of a trilobite-gastropod-bearing limestone (or sandstone in part) which adjoins the slate belt closely to the west and northwest. Ulrich and Schuchert see in the parallelism of the two different faunas and rock series (Phyllograptus shales and Chazy limestone) proof of the pres- ence of twin channels, the Levis channel and Chazy basin, stat- ing that “the respective faunas and the lithologic character of the deposits in the twin channels are so different that we can not doubt the thorough effectiveness of the Quebec barrier dur- ing the whole of Chazy time.” Accepting, for the purpose of further argument, the correctness of the postulation of this bar- rier to explain the stated facts, it follows that a like barrier of equal extent must be postulated for the late Cambric time, and that the beginning of the elevation of this “‘ Quebec” barrier, the northern extension of the “Appalachian valley fold”, must be placed in late Cambric time, instead of at the beginning of 958 NEW YORK STATE MUSEUM Chazy time. Toward the east the Levis channel was bounded by the Green mountains fold, which is supposed to have already emerged in middle Cambric time. This, as far as our knowledge goes, bounds also the upper Cambric graptolite shale. Ulrich and Schuchert hold that the region of the later Levis channel had emerged during the Potsdam period [see the un- classified time scale, opposite page 658, J. c.]. This is in accord- ‘ance with Professor Dale’s conclusions,! who not only found the middle and upper Cambric beds to be missing, but also observed an unconformity between the Lower Siluric and Lower | Cambric, indicating the emergence of the lower Cambric beds during the succeeding Cambric time. Our observations agree thus far fully with these results of Mr Dale’s elaborate investi- gation with the exception of the closing upper Cambric time, represented by the Dictyonema shale. Toward the west and north of this strip of upper Cambric land, forming the “ Vorland” of the Green mountain fold, ex- tended the more or less broad “St Lawrence channel,” which effected the communication between the Atlantic and Missis- Sippian seas, indicated by the distribution of the Dicellocephalus fauna. The question whether this late Cambric “ Levis” channel per- sisted throughout the Beekmantown period in this southern part of the present slate belt or the broader St Lawrence channel extended freely from the Adirondacks to the Green mountains is a problem, the solution of which is dependent partly on the exact correlation of the limestones occurring in the slate belt and partly on that of the three Deep kill zones of graptolites, corresponding to the Phylograptus horizous of Europe. It will necessitate much detailed investigation to obtain conclusive facts and to decide between the differing views held in regard to these beds. ‘New York-Vermont State Belt, U.S. Geol.

WOODWORTH In the course of an examination of the Pleistocene deposits of the Mooers quadrangle, including the township of Mooers, in Clinton county, N. Y., in the summer of 1902, I had my atten- tion called to certain trails on the Potsdam sandstone in that town which are remarkable for their distinctness and association with terminal impressions not heretofore described. Having seen the trails of Climactichnites on a flagstone in the main street of the village of Mooers, I was led to inquire for the quarry whence the stone was derived, and, though I did not learn whence the slab came, I was informed by the postmaster of the tracks which it is the object of this paper to describe. The trails (Climactichnites) described in this paper occur in the town of Mooers on the west side of the Mooers branch of the Delaware and Hudson Railroad a few rods south of what is known locally as Bidwell’s crossing, on the land of Mr B. H. Palmer, at the first rock cut in the railroad north of Sciota and distant from that station somewhat less than 2 miles. The Potsdam sandstone is here practically horizontal and is exposed in the rock cut as a badly shaken, irregularly splitting series of prevailingly light colored sandstones. The track layer is exposed in the adjoining field in the wave-swept trough between two of the small beach ridges of the postglacial marine stage of the Champlain valley. The track layer, where its edge is exposed, has a thickness of 8 inches; it is traversed by several rudely parallel joints cutting all of the longer trails. The area ex- posed at the time of my visit was about 50 feet long and varying in width from a yard to over two yards. | The trails appear to have been first noted by the present owner of the land, who states that he cleared away some of the surface debris several years ago. Locally the trails are spoken of as those “serpents,” and the impressions associated with them as “human footprints.” O IMIASLH SIND ertccce 3B VIASLACT BaAcwH®? whe s InvhA =TIASNNId “e,e JIIIWIASNOANT Ati> nwI0u grr” voA NW3AN nJdICONUY a ee ymey Lamy} 37v2S "lr 938Id DEVONIC AND CARBONIC FORMATIONS OF SOUTH- WESTERN NEW YORK With stratigraphic map of the Olean quadrangle BY L. C. GLENN INTRODUCTION Basis of paper. During the summer of 1900 the detailed geolo- gic mapping of the Olean and Salamanca quadrangles in south- western New York [see pl. 1] was undertaken by the United States Geological Survey in cooperation with the New York State Paleontologist, and the writer was placed in charge of the work. The work was continued and finished the next summer. Mr Myron L. Fuller assisted largely in the work on the Salamanca quad- rangle during the latter season, and in both seasons Mr Charles Butts made extensive paleontologic collections from the two quadrangles and the adjacent region. Reconnaissance work was pushed southward to Bingham Pa. and westward across McKean and Warren counties to near Corry Pa. Age of rocks and problems involved. The paleozoic rocks ex- posed in the quadrangle extend from about the middle of the Chemung up into the Carbonic. They consequently include the Catskill or its equivalent and the boundary or transition be- tween the Devonic and the Carbonic. Eastward in both New York and Pennsylvania the distribution of the Chemung, the Catskill and the Carbonic rocks and their relationship to each other have received much study. Southward in Pennsylvania the Carbonic rocks have been studied and the lower Carbonic traced northward toward this region. To the west in Ohio the Carbonic and Waverly have been studied and traced eastward for some distance into northwestern Pennsylvania. The Olean- Salamanca region, however, has been an unknown meeting ground into which, when attempts were made to trace beds that were distinct to the east, the south or the west, the tracings became indistinct and the correlations uncertain. Purpose of paper. It is the main purpose of this paper to de- scribe briefly the stratigraphic succession found in the Olean- Salamanca region, to state the paleontologie conclusions so far reached as to the age of the formations, and the results of the efforts made to trace these formations into better known re- . 968 NEW YORK STATE MUSEUM gions southward and westward in McKean and Warren counties Pennsylvania. Topography. Topographically the region is a maturely dis- .sected one. The hills rise with steep slopes to an elevation of 500 to 1000 feet above the main stream levels. The northern portion of the two quadrangles is glaciated and exposures of rock in place are infrequent. Much of the southern portion and of the reconnaissance area in Pennsylvania is wild and wooded, and overgrown in many places with a dense tangle of bushes, briers and vines that both conceals exposures and ren- ders the work of the geologist difficult and slow. Structure. The dominant structure is that of flat lying beds dipping gently a little west of south at an average rate of about 30 feet a mile. Here and there the dip is locally increased or decreased and in the Olean and eastern Salamanca area just south of the Allegheny river it is for a short distance reversed. Some sharp minor folding occurs in the Olean conglomerate south of Olean along the high ridge extending from Flatiron rock to Knapp’s creek and beyond. This folding is entirely taken up in the 1800 feet of shales that intervene between the Olean conglomerate and the Bradford oil sand which is pene trated by many wells at this depth and shows no sign of folding. In the Salamanca region some low rolls or folds with northeast southwest axes were noted by Mr Fuller. STRATIGRAPHY DEVONIC FORMATIONS Chemung beds Description of Chemung shales and of Cuba sandstone lentil. The oldest rocks in the region are those near stream level in the northeastern part of the Olean quadrangle. They are typical Chemung shales and extend upward some 700 to 750 feet. Of these the very lowest beds consist of 30 or 40 feet of fine olive green, argillaceous shale, seen best exposed in railway and other cuttings near Cuba. An excellent exposure may be seen a few yards east of the Erie depot at Cuba. In the railway cut 20 feet of it are exposed and nearly 20 feet more may be seen in the gutter by the side of the street leading down into the town. It is here fine grained and weathers into very small fragments. REPORT OF THE STATE PALEONTOLOGIST 1902 969 When fresh the lower part is bluish in color and the upper part green, but it weathers to-a rusty brown from its iron content. It is sparingly fossiliferous. Immediately above these shales there is a sandstone 10 to 15 feet thick, most prominently exposed in and north of Cuba in a number of quarry openings. It is a medium to coarse grained, somewhat arkosic sandstone, usually of a light cream- eolor and smelling strongly of petroleum on freshly fractured surfaces. As seen in a quarry a few rods east of the Erie depot in Cuba there are exposed at the base 8 feet of thick bedded, hard, cream-colored sandstone, above them two feet of green and brownish shale, then two feet of sandstone abundantly fossilif- erous. Above these are about 12 feet of sandy olive shale that weathers to a rusty brown, then 2 feet of thin-bedded flaggy sandstone, above which are seen to the top of the opening 8 feet of interbedded shales and thin shaly sandstone plates. The lower 10 feet of the sandstone are quarried. In places the stone is stained with iron along joints and seams. Fossils occur rather abundantly in certain layers and in the coarser parts an occasional small quartz pebble is found. Other,quarry openings are found in and near Cuba. At North Cuba the rock has been opened at several places and probably furnished the stone for the dam of the old canal reservoir there. The region in which it occurs above water level is glaciated and almost all outcrops are concealed by till. It extends from North Cuba and Ischua, however, down Oil and Ischua creeks to near their junction where its dip carries it beneath flood plain level. A solitary exposure of sandstone having the same general appearance, situated at about the same geologic horizon, and earrying the same characteristic Cuba sandstone fossils is found in a Buffalo, Rochester and Pittsburg Railway cut north of Great Valley on the Salamanca quadrangle and has been correlated with the Cuba sandstone. All other exposures along Great Valley creek are entirely concealed by the drift so that its areal extent there is unknown. From its exposure in quarries in and around Cuba this sand- stone is known as the Cuba sandstone. It is regarded as a jentil in the Chemung formation. 970 NEW YORK STATE MUSEUM Above the Cuba sandstone lentil the Chemung is composed of green and brownish argillaceous.and sandy shales, inter- bedded here and there with thin shaly sandstones. With the probable exception of certain dark purplish shales to be described presently, the individual beds of neither the shales nor the shaly sandstones usually retain their thickness or individuality or possess any lithologic character that would enable any one of them to be traced and identified for any dis- tance. The nearest approach to persistency in these variable beds is found in a sandy zone about 200 feet above the Cuba sandstone. A number of quarries have been opened in the past on some argillaceous sandstones at this horizon. The stone is fine grained and soft and is more accurately described perhaps, as a shaly sandstone that varies into an indurated mudstone. When exposed to the weather the outside scales off or cracks and seams develop, so that in each quarry opened it was soon found to lack durability. All these quarries are abandoned today but at intervals along either valley wall of Oil and Olean creeks from one a few miles above Hinsdale that furnished material for: locks for the old state canal to ones to the west and to the south of Olean may be Seen the old openings. But even this sandy zone, persistent as it is as a whole, well illustrates the variability in detail of these Chemung strata for often in one quarry face there is visible a complete change along the bedding plane from one lithologic phase to another, so that as a whole these Chemung shales and argillaceous sandstones are only regular in their irregularity and intergradation. The one exception as regards the rapid variability of these shales is found in certain dark purple or chocolate colored shales about 325 to 350 feet below the top of the Chemung. These are largely sandy and interbedded with thin plates of very shaly sandstone often of about the same color. They sometimes have a reddish cast but it is always a very dark brick red never a bright red. They seem to be widely persistent and are found in many well borings to the south. Their top occurs in the Dennis well at Bradford Pa. at a depth of 712 feet. In a few places south of Cuba some faint traces of oolitic iron ore are found in the shales a hundred feet or more above REPORT OF THE STATE PALEONTOLOGIST 1902 971 the Cuba sandstone. They seem to be of local development and even in this region are scarcely worth mentioning. Ata number of horizons the shales become locally calcareous and a bed 6, 8, or even 10 inches thick may pass into a very impure limestone that where exposed on the surface has usually been leached out into a honeycombed mass of brachiopod casts and molds. These thin beds weather into: soft rusty blocks or ehunks that are often very conspicuous on the surface. In many places the sandy shales and thin shaly sandstones, specially near the top of the Chemung, are stained bluish black by manganese. Ripple markings are common at various horizons and in a few places what may possibly be obscure mud eracks are found. Minute mica scales often fleck the parting planes of the thin shaly argillaceous sandstones. As a rule the Chemung strata are abundantly fossiliferous. Brachiopods and lamellibranchs are the most abundant forms while in some of the abandoned quarries above mentioned sponges are also to be found. | Cattaraugus beds Wolf creek conglomerate lentil. A marked change in the con- ditions of sedimentation caused the deposition of a conglom- erate that is most prominently developed on Wolf creek and is kuown as the Wolf creek conglomerate. Its pebbles are predominantly flat or discoidal and hence it is also often called the “flat pebble” conglomerate in contradistinction to the Olean or “round pebble” conglomerate occurring higher in the series. The pebbles are mostly of vein quartz though a few are of red jasper. They vary in size from an inch or two in diameter down to ones of coffee or wheat grain size. Pebbles of the larger size are not abundant. The average size is per- haps less than a half inch in diameter. The mass of the rock is as a rule a coarse, loosely cemented, cross bedded sand sometimes bleached white but usually stained yellow or brown by iron. In some places on Wolf creek it becomes locally massive, and projects from the valley walls in ledges 15 to 20 _feet high from which large blocks are shed into the valley below. One of the most prominent characteristics of this conglomerate is its rapid variation in thickness. Nowhere more than about 20 feet thick, it often in a few hundred yards thins 972 NEW YORK STATE MUSEUM down to a few inches in thickness. It was at first thought that these thicker portions might mark an old stream channel but a careful mapping of them failed to reveal any relation te a possible stream course. Notwithstanding its rapid variation in thickness it was found to be a remarkably persistent stratum over the Olean and the eastern part of the Salamanca sheet and was the key rock for determining the stratigraphy of much of this region. Its maximum thickness of about 20 feet is found in only a few localities and these are on Wolf creek. Elsewhere in the Wolf creek region it is frequently found 5 to 10 feet thick, but over-by far the larger part of the area in which it is known to occur in these two quadrangles it is only from a few inches to a foot or two thick and consequently is not a conspicuous stratum and is rarely exposed in a natural outcrop. Its horizon in numerous places is determinable only by tracing up a hillside loose pieces on the surface to the highest point at which they can be found and then working along at this elevation till the upper limit of loose material is well established. Even in a part of the region where it is, as a rule, very inconspicuous it may for a short distance thicken materially, as for instance northeast of Carrollton where it is locally 10 or 12 feet thick, and it is entirely possible that in the portion of the Salamanca quadrangle where it is not known to occur and where its horizon is indicated by the dotted geologic boundary line between the Chemung and the Cattarat gus there may be here and there spots where a few inches or @ few feet of it are to be found. The beds occasionally contain a fair to good representation of marine fossils the assemblage of which is characteristic of this horizon. It marks the first prom- inent change in sedimentary conditions in the region and is re- garded as a lentil marking the base of, and belonging to, the Cattaraugus formation. Shales and sandstones. The deposition of the Wolf creek con- glomerate was succeeded by conditions that caused the deposition of bright red shales interbedded with green or blnish shales and fine grained, greenish gray, thin bedded, micaceous sandstones that together extend upward through an average interval of 300 to 350 feet. This portion of the stratigraphic column in which bright red shales occur, and REPORT OF THE STATE PALEONTOLOGIST 1902 973 which extends upward from the base of the Wolf creek con- glomerate lentil in the Olean region to a limonitie shale pres- ently to be characterized, is regarded as a formation and to it the name Cattaraugus is given. Two other conglomerate lentils occur in it, the Salamanca and the Kilbuck. The bright red argillaceous shales of the Cattaraugus are entirely different from the dark brick red or purplish shales of the Chemung and need never be confused with them. No bright red shales occur anywhere in this region below the Wolf creek eonglomerate but they do appear within a few feet above it. They are usually fine grained and argillaceous though in many places they become sandy and may locally pass into a thin red argillaceous sandstone. Specially does this transition occur in the southeastern part of the Olean area and in eastern McKean county, Pa. It is not certain that the individual beds ef red shale are persistent or hold their thickness for more than short distances, but it is certain that as one goes west- ward into the Salamanca region and southwestward into War- ren county, Pa. the beds of red shale tend to disappear. Their disappearance appears to be due not to a lack of deposition in this area at that time, nor to their once having been depos- ited and subsequently removed from the entire region by erosion before the deposition of the overlying formations but to their grading over westward and southwestward into deposits of other than red color. The stratigraphic equivalents ef the red shales are as a rule present to the westward but their color has changed to olive-green, blue or drab. At the same time there is some evidence that erosion occurred in this region after the deposition of the beds containing these red shales as will be seen somewhat later. The lighter colored shales interbedded with the red ones vary from fine blue mud shales to light or dark green sandy ones. Along with the shales are greenish gray, medium to fine grained, soft, arkosic sandstones often thin or cross bedded and with their parting planes flecked with mica particles. By the oxidation of their iron content these sandstones weather into a red soil just as the red shales do. These sandstones have been quarried and sawed into flagging at the Cook quarry a few miles south of Olean, though no work is now being done 974 NEW YORK STATE MUSEUM at this place. The individual beds of sandstone do not seem to be persistent except for short distances. There is found, however, in a number of places in the Olean region a rust- colored sandstone layer filled with limonitic concretions and containing fish remains, but whether these exposures belong to one persistent horizon or not is uncertain. To the southwest near Warren Pa. fish remains are known to occur at several horizons. Fossils. After the deposition of the Wolf creek conglomerate which contains in its upper portion specially a marine fauna, fossils rapidly disappear and the red and green shales and the fine micaceous sandstones generally yield but few or, for con- siderable intervals, no forms. In many places, specially in the sandstones, fossils are entirely wanting. Conditions as a whole were evidently unfavorable to animal life while these beds were being deposited. Some fish remains occur as mentioned above and the Salamanca and Kilbuck conglomerate lentils are fossiliferous. Salamanca conglomerate lentil. The Salamanca lentil occurs at about the middle of the Cattaraugus formation. It thins out and disappears to the eastward, not being known to occur on the Olean quadrangle to the northeast of the Allegheny river and Oswayo creek. South and west of this line it occurs in the Olean area as a hard gray sandstone 10 to 15 feet thick, which becomes coarser and thicker westward and passes into a massive conglomerate on the Salamanca quadrangle. The sandstone phase is well exposed in a number of small quarries on Mount — Hermon just south of Olean where it is locally known as the Mount Hermon sandstone. It is there a medium to a coarse erained sandstone carrying an occasional small quartz pebble. It is generally cream-colored to gray though some layers are dotted with innumerable small rust-colored spots that have resulted from the decomposition of iron pyrite. The bedding here is usually regular and the thickness of a given bed uni- form for at least some distance. The layers of from 8 to 16 inches in thickness are separated by thin shale films or partings that render their removal easy. It weathers into hard, white, parallel-sided blocks that are pierced by many vertical fucoid tubes or stems. These fucoids are often very prominent and are REPORT OF THE STATE PALEONTOLOGIST 1902 975 a characteristic feature of the weathered blocks in the Olean region. Its massive conglomeritic character is best developed in the Salamanca region and may be well seen up Limestone and Irish brooks, along Red House creek, at Salamanca rock city where it weathers into great blocks, and at numerous other places. In thickness, coarseness and massiveness it is also variable though not as markedly or abruptly so as the Wolf creek. In its more massive phase it is often strongly cross bedded and in places is separated into two benches with a shale parting be- tween. The pebbles are mostly of vein quartz and the great majority of them are distinctly flattened like those of the Wolf creek and, like the lattér also, they include an occasional one of red jasper. Even when coarsest and most massive the peb- bles do not appear as prominent or form as large a proportion of the mass as they do in the Olean conglomerate. The bulk of the rock consists of a coarse, gritty sand. The average size of the pebbles is small and they are usually distributed through the mass of the rock not uniformly but in thin streaks along the planes of the cross bedding. The difference between the flatness of the pebbles of the Wolf. creek, the Salamanca, the Kilbuck and the two thin con- glomerates just below the Olean and the roundness of the peb- bles of the Olean itself was first noticed by Carll! whose ex- planation of their flatness as due to beach action would seem to be correct. He regarded older shore deposits lying to the north as the source of the pebbly materials. As the presence of the occasional jasper pebbles among the flattened quartz ones in all of the conglomerate beds in the region below the Olean or round pebble conglomerate gives suffii- cient gounds for concluding, it is believed by the writer that the coarse materials of these lower, or flat pebble conglom- erates, were derived from the Lake Superior region and were transported eastward along the shore by the waves and long shore currents of the Devonic and Carbonic seas, the flat- tened or discoid form so characteristic of the pebbles of these lower conglomerates being produced by their to and fro mo- tion along the beach during this long eastward journey. Carll, J. F. Geol. Sur. Pa. Rep’t I,, p. 60, 61; I,, p. 190-92 “976 NEW YORK STATE MUSEUM The round or ovoid pebbles of the Olean conglomerate which contains no jasper pebbles, it is further believed were not trans- ported along the beach but were brought down from the ancient land masses to the north and east and were rolled over and over and rounded by the stream currents that carried them into the Carbonic sea. The flattened pebbles were beach fashioned, the rounded ones stream made. The total maximum thickness in the Olean-Salamanea region is rarely over 30 feet and probably never exceeds 40. Much confusion and uncertainty has arisen in the Salamanca region as to the number of conglomerates present beneath what has generally been called the Subolean. This is specially true of that region bordering the valley of the Tunangwant or Tuna. Various correlations, some of which, however, were recognized as provisional, have been made for the same outcrops, and dif- ferent outcrops of the same conglomerate have often been re- . garded as belonging to different horizons. The names Salamanca, Panama, Pope Hollow, Wrightsville and even Subolean (?) have all been applied in this region to the same conglomerate some of them being regarded by some as synonyms but the belief being prevalent that two or three conglomerates are present in the Tuna section. ‘+Lesley for in- stance, believed there is lowest a Salamanca (Panama?) con- glomerate, above it a Tuna-Pope Hollow-Wrightsville conglomer- ate horizon and above that an Ireland-Subolean (?) one. J. F. Carll? believes that at least 225 feet above the Salamanca con- glomerate the Tuna occurs and is the equivalent of the Ireland Subolean (?) of Lesley and probably the equivalent of the Pope Hollow-Wrightsville conglomerate found farther west. F. A. Randall? recognizes in the Tuna region a lower or Panama and an upper or Pope Hollow conglomerate and thinks it probable that the Salamanca is the equivalent of the Pope Hollow. The lower conglomerate found by Randall northeast of Carrollton and up Baillett brook and perhaps in a few other neighboring localities is the Wolf creek here locally much thickened as com- 1 Lesley, J.

His higher con- glomerate is the Salamanca. : ‘The Salamanca, the Panama, the Pope Hollow and the Tuna are the same conglomerate and Lesley’s supposed third or Subolean(?) conglomerate at Ireland near the head of Irish brook is also an excellent outcrop of the Salamanca, here quite massive. The-confusion has mainly resulted from assuming a regular dip for the Salamanca and then concluding that a conglomerate found too high or too low at a given locality for the calculated position of the Salamanca at that place belonged to a different horizon. Dips, however, are not regular in this region. A local northward reversal of dip occurs near the mouth of the Tuna and again just southeast of Salamanca and several small rolls or gentle irregular folds with northeast southwest axes occur in the Salamanca area. These irregu- larities render such dip calculations misleading. Kilbuck conglomerate lentil. On the Salamanca sheet there is found in the Cattaraugus formation a third conglomerate lentil lying 50 to 70 feet above the Salamanca conglomerate and called by Mr Fuller the Kilbuck. It has much the same flat peb- ble character as the underlying Salamanca. It is not over 10 to 15 feet thick as a maximum but in places is quite massive and weathers into large flat blocks that, where topographic con- ditions favor, form a pavement over considerable areas. It is best developed northeast and east of Kilbuck and extends as far east as the ridge at the head of Tenmile creek. It is also found north of Salamanca and on the high ridge south of Sala- manca and east of Red House brook as far south as the head of Irish brook. A small area occurs on the ridge east of the Tuna and north of the head of Leonard brook. It is thus seen to be of local development, but has possibly added to the difficulties of making correct correlations in this region. Probable unconformity. The top of the Cattaraugus formation is difficult to determine with exactness in most places since its upper portion consists of soft shales and it is succeeded by other soft shales. Exposures are in consequence poor except along roadways or pipe lines. Numerous measures, however, that are deemed reliable have been obtained of the thickness of that part of the formation which lies above the top of the 978 NEW: YCRK STATE MUSEUM Salamanca conglomerate lentil. A comparison of these figures shows that this thickness frequently varies irregularly and very materially within short distances. The interval from the top of the Salamanca to the top of the Cattaraugus near Flat- iron is 65 feet, southwest of Knapp’s creek it is about 145 feet. In the Dennis well at Bradford Pa. it is 84 feet. At the head of Chipmunk creek it is about 90 feet. East of Chipmunk it is 110 feet in one place and in another near by more than 145 feet. At the head of Leonard brook it is 180 feet, northward at the head of Baillett brook it is 220 feet, while still north beyond the Allegheny it is only 100 feet on the knob east of Carrollton. In several places in the Limestone-Irish brook region it is 100 feet or less while just north of Rice brook it is at least 230 feet. On the southeast side of upper Red House brook it is 110 feet while on the northwest side it is over 210 feet. At the triangulation station southeast of Salamanca it is 215 feet or less, a mile and a half north it is 240 feet or more. It is not thought probable that mere local variations in the thickness of the strata of the Cattaraugus could be rapid enough and great enough to account for the irregular vyaria- tions that have just been mentioned in the thickness of that part of this formation which lies above the Salamanca con- glomerate lentil. It seems more probable that the upper surface of the Cattaraugus is irregular because of erosion and that there is consequently an unconformity at this point repre- senting an erosion interval between the Cattaraugus and the succeeding Oswayo. CARBONIC FORMATIONS Oswayo beds Composition. The close of the Cattaraugus stage was marked by the cessation of the deposition of red shales in this region. After what is believed to have been an erosion interval it was followed by the deposition of olive-green to rusty colored sandy shales, with here and there thin sandstone layers with Jimonitic seams or incrustations. These greenish, limonitic shales constitute the Oswayo formation. Its thickness varies from 160 to 250 feet, the average being near the latter number. Conditions now became more favorable to the existence of life and, in contrast to the usual barrenness of the red shales ee, a Dl REPORT OF THE STATE PALEONTOLOGIST 1902 979 below, the Oswayo contains in many places a fairly good repre- sentation of marine invertebrates, prominent among which is Camarotoechia allegania, which serves as an excel- lent horizon-marker. Limestone layer. A few feet above the base of the Oswayo shale, is found in a number of places in New York what seems to be a persistent layer of very impure limestone. It is only one or two feet thick and in places is separated into two layers with several feet of shale between. This limestone is com- posed of innumerable fragments of badly broken brachiopod and other marine shells. It might almost be termed a shell conglomerate. In places it also includes bryozoan remains. One of the best exposures is seen in an abandoned railway cut at the burned power-house on the electric road about a mile north of Olean rock city. It is again found just off the Sala- manca quadrangle on both the present and the abandoned line of the electric road southwest of Knapp’s creek in several places. Near the head of Nichols run on the hill southeast of Limestone and at the head of the western branch of Red House brook along an abandoned railway grade just beyond the edge of the Salamanca quadrangle it is again found. It is probably the same as a very similar limestone which the writer has examined at a number of places in McKean county, Pa. and which is called by Ashburner! the Marvin creek limestone with the suggestion that it is probably the same as the Lower Mead- ville limestone of Crawford county. On the Olean quadrangle a few small areas of Oswayo shales are found on the highest crests north and east of Portville, but they are mainly found on the highest ridges south of the Alle- gheny river and in this region extend up to the base of the Olean conglomerate. Near their top they become sandier and the number of thin limonitic sandstone plates increases. On the Salamanca quadrangle the largest areas of Oswayo shales are found south of the Allegheny river. They occur on almost every prominent ridge. North of the river the only areas of any size are those on the ridge crests on either side of Tenmile creek. — —— —— - —— —— 1Ashburner, C. A. Sec. Geol. Sur. Pa. Rep’t R, p. 68-69. 980 NEW YORK STATE MUSEUM At Olean rock city there are some traces of grits some forty or more feet below the base of the Olean conglomerate. . No- where on this quadrangle, however, have such gritty beds been found exposed in place and at several points good exposures of this part of the section are to be seen, as for instance on the road from Fourmile down into Fourmile creek valley. The trace of grit at the rock city may be the equivalent of one or the other — probably the lower — of the two thin conglom- erate beds found interbedded with shales and lying just beneath the Olean conglomerate westward at Knapp’s creek and else- where on the Salamanca quadrangle, and which will presently be described. If so, these coarser beds have so fined down and lost their characteristics that it becomes impossible to separate them on the Olean quadrangle from the Oswayo shales beneath and both are on this quadrangle accordingly mapped together under the name of the Oswayo. It is very probable that over most of the small area on the Olean quadrangle where the upper part of the Oswayo shale occurs the very topmost beds, which are the equivalent of the grits and interbedded shales westward, were eroded before the deposition of the Olean and consequently that even if this part were lithologically separable fromm the Oswayo there would be very little of it to map. Knapp beds On the Salamanca quadrangle there are found beneath the Olean conglomerate two thin conglomerates interbedded with shales that are lithologically very similar to the underlying Oswayo shales. These are doubtless in part at least the equiva- lents of the grits and shales just beneath the Olean at rock city and which are included in the Oswayo there but which evidently thicken and coarsen westward till they are capable of differ- entiation as the Knapp formation. These beds are not usually well developed on the Salamanca quadrangle and have been found in only a few areas along the southern edge. Southwest- ward in Pennsylvania a more prominent conglomerate known as the Subolean is situated in a similar stratigraphic position be neath the Olean from which it is separated by from 25 to 50 feet of shales. It is known over a large area and extends according to the Pennsylvania geologists westward into Ohio where it is —_— ee es REPORT OF THE STATE PALEONTOLOGIST 1902 981 known as the Shenango conglomerate. It with the associated Shenango shales is probably the equivalent of this Knapp formation. The coarser part of this formation is usually a loosely ce- mented conglomerate with small well smoothed quartz pebbles of flattened discoidal shape that only in places becomes massive. It is frequently highly limonitiec and in most places where exam- ined was fossiliferous. The fossils consist of marine inverte- brates and plant stems of various kinds. The shales are sandy and olive-green or rusty brown and in several places have been found to contain marine invertebrates. The most eastern exposure of these beds is found at Knapp’s Creek Station. Here there are two coarse beds separated by a varying thickness of shale. In the gutter beside the road lead- ing from Knapp’s Creek Station down into the head of Fourmile creek, in the interval from 20 to 40 feet below the station level, is found a thin bedded gritty to pebbly sandstone heavily charged with iron and containing marine invertebrate fossils. The layers are separated by partings of blue clay shales. A few hundred vards west of the station along the electric road just before reaching the summit there is a second sandstone about 40 feet higher than the first one, the interval between being occupied by sandy ferruginous shales. This sandstone is hard and gray and rings under the hammer. It is bedded in layers a few inches thick, some of which contain a few pebbles. The layers are separated by ferruginous sandy shales. It is also fossiliferous bearing among other forms Syringothyris. Above it are perhaps 20 feet of shale before the base of the Olean is reached. Beyond the summit one passes down through the Same succession in reverse order, the upper sandstone being about 5 feet thick and more conglomeritic, the underlying shale being 20 feet thick and the lower coarse bed consisting of 20 feet of thin conglomerate and sandstone interbedded with shale, the pebbles being chiefly of wheat grain to coffee grain size. Both beds are again fossiliferous. These beds — specially the upper one — are found exposed at intervals along the ridge westward nearly to Harrisburg. At Harrisburg and to the northwest they have been cut out and several small areas of 982 NEW YORK STATE MUSEUM Olean conglomerate lie at a lower elevation than these underly- ing beds do just to the south and east. The best development of this formation in the Salamanca quadrangle is found on the ridge southwest of Limestone near the Pennsylvania line. These two thin conglomerates again occur just beneath the Olean. They are very well exposed along the pipe line crossing this ridge. Each is more massive and more conglomeritic than in the Knapp’s creek area. The upper one at least is fossiliferous. They are each 10 to 15 feet thick. The shale interval between varies from 30 to 40 feet in thick- ness and is fossiliferous, containing among other forms Syringo- thyris again. There are about 25 or 30 feet of shale between the upper conglomerate and the base of the Olean. Farther south and west only one conglomerate known as the Subolean has been seen by the writer beneath the Olean and the shale interval is usually great enough to make it seem most probable that this one conglomerate is the lower of the two in the above mentioned localities, if both have not united westward. In some other places also these beds seem to have been cut out by erosion before the deposition of the Olean conglom- erate, as, for instance, on the ridge north of the head of Irish brook, where Olean caps the hill but with no sign of an under- Jying conglomerate beneath. The same thing is true at Miller’s cliff in Warren county, Pa., where the Olean occurs, but beneath it the Subolean is wanting. There is consequently - believed to be an unconformity between the Olean and the underlying formations in this region and from differences of level in the base of the Olean as exposed in outcrops often but short distances apart, the floor upon which the Olean was deposited must have been a very irregular one. Pottsville beds Olean conglomerate. Next comes a massive round pebbled conglomerate widely known as the Olean conglomerate. In texture the Olean often varies quite rapidly both horizontally and vertically. In some places or in some beds it is scarcely more than a coarse sandstone with a sparing development of pebbles, while at other places or in other layers at the same place, it is almost entirely composed of rounded quartz pebbles. If any rule holds good the lower part is more frequently con- REPORT OF THE STATE PALEONTOLOGIST 1902. 983 glomeritic and the upper part a coarse, cream-colored sand- stone that weathers white on exposure. It is almost always strongly cross bedded. The pebbles are well rounded and in contrast to the flattened or discoidal pebbles of all of the under- lying conglomerates in the region are predominantly ovoid in shape so that the Olean is frequently referred to as the “ round pebble conglomerate.” While flat pebbles do occur in it, yet the proportion of round or ovoid ones is so great that the distinction is good. These pebbles vary in size up to two or three inches in diameter though the average diameter is some- what less. Most of them are of vein quartz; a few are of a hard, dark gray slate; none are of red jasper. They are loosely embedded in a very arkosic sandy matrix, in portions of which there is considerable iron which has formed thin limonitic streaks or crusts through the rock and resists disintegration much better than the arkosic cement does. Etched quartz pebbles. Pebbles of vein quartz embedded in surfaces made of such limonitic crusts are frequently found much etched or corroded. The only part played by the limonitic crust is the holding of the same pebbles exposed on its surface for some time till the etching agent has had time to greatly corrode them. The nature of the etching agent is not certainly known. It is generally thought to be some one of the humic acids that result from plant decay. The best examples of such etching seen in the region by the writer are in shallow depressions in which water stands after a rain on the upper surface of the blocks that make up the Genesee rock city. These huge blocks are on the top of a high crest in a field with only one tree near that rises above them. The upper surface of the blocks is bare except for a very few submicroscopic plant forms which may possibly by their decay furnish a corroding agent, though this impressed the writer when examining them as not being an adequate cause. The next best example of etching is found at Olean rock city. Here both the cause and one rather diagnostic step in the process seem more satisfactorily determinable. On the under surface of overhanging portions of the rock so situated 984 NEW YORK STATE MUSEUM that they could not be wet by rain or receive drippings from any surface above were found many small well etched pebbles of vein.quartz. These under surfaces of the rock were very appreciably moist, however, even on a hot summer day. This moisture was derived partly by seepage of contained moisture down through the loosely cemented rock itself and partly by direct condensation of moisture from the atmosphere, since from their sheltered position these surfaces remain quite cool even on the hottest days. If due to an organic acid of decompo- sition, this acid must have reached the etched under surface by soaking through some 30 or 40 feet at least or rock. Why it has not attacked and corroded the many quartz pebbles passed on its way through the rock, but has preferred to wait till it has reached the under surface before becoming chemically active seems explicable on the theory advanced by Dr C. W. Hayes'. The acid was probably humic and so was compara- tively inert till it had come into free contact with the atmosphere on reaching the underside of the ledge, where it absorbed nitrogen from the air forming azohumic acid which has a strong affinity for silica and at once began corroding the quartz pebbles. These somewhat exceptional conditions at Olean rock city seem most readily explicable on this theory and they in turn lend additional strength to the theory itself. Disintegration of the Olean is as a rule very rapid and talus slopes occur everywhere so that the base is rarely or never exposed. Numerous well borings have penetrated it, however, on the Olean quadrangle and give an accurate measure of its thickness there which is usually between 60 and 70 feet, though in one well it is 90 feet. It occurs on the highest hilltops in the southern part of the two quadrangles, in a number of small detached areas and is well known southward in McKean county and westward in Warren county in Pennsylvania. Above the Olean conglomerate at rock city are found a few feet of thin, sandy, ferruginous shales in which some years ago a thin coal bloom was exposed in grading a road. It also belongs to the Pottsville. 1 Hayes, C. W. Solution of Silica under Atmospheric Conditions. Geol. Soc. Amer. Bul. 8:213-20. REPORT OF THE STATE PALEONTOLOGIST 1902 985 AGE OF FORMATIONS Paleontologic work. The extensive collections of fossils made by Mr Charles Butts were studied by him at Albany under Dr J. M. Clarke’s supervision. Prof. H. S. Williams has also studied similar collections made some years ago by himself and his assistants in this region and the paleontologic facts stated below concerning faunal affinities are those ascertained as a re- sult of the investigations of Dr Clarke, Dr Williams and Mr Butts. Additional facts bearing on the paleontologic problems of the region may soon be expected as a result of the further studies now in progress by Drs Clarke and Williams. The conclusions which the writer has drawn from these paleontologic facts he alone is to be held responsible for. The shales extending from the lowest exposures up to the base of the Wolf creek conglomerate contain an abundant Chemung fauna and are considered to be of Chemung age. The first Car- bonic life forms appear with the incoming of the Wolf creek con- glomerate and from this point up to practically the base of the Olean conglomerate at Olean rock city where the last Devonic forms disappear, there is a mingling of Devonic and Carbonic forms, the Devonic slowly decreasing, the Carbonic slowly in- creasing. The essential fact so far as the life of these Catta- raugus and Oswayo formations is concerned is that there is an overlapping of Devonic and Carbonic faunas. With this essen- tial fact recognized the position at which the boundary line between the Devonic and the Carbonic shall be drawn becomes, in some measure at least, a matter of convention. It might appear best for some reasons to draw this line at the base of the Wolf creek where Carbonic forms first appear and consider both the Cattaraugus red beds and the Oswayo and Knapp formations as Lower Carbonic. This would make the top of the Chemung the top of the Devonic and would make the Subcarbonic average about 600 feet thick in this region. Because of the thickness of these red beds and their reason- ably certain stratigraphic equivalence with the red beds of the Catskill to the east, and because of the unconformity believed to exist between the Cattaraugus and the Oswayo, the writer pre- fers to draw a provisional boundary between the Devonic and the Carbonic at this point. This would make the Subcarbonie 986 NEW YORK STATE MUSEUM 300 to 350 feet thick here and would make the top of the red beds the top of the Devonic. All of the facts bearing on this difficult Devono-Carbonie boundary problem will not be at hand till paleontologic re- searches from both the Devonic and Carbonic starting points have been finished and detailed stratigraphic work has been carried eastward, southward and westward to connect with bet- ter known and more clearly differentiated areas in these direc- tions. Hence this boundary is to be recognized and accepted as distinctly provisional only and is subject to such change as later investigations of the stratigraphy and paleontology of the adjacent regions may warrant. The Olean has been agreed on as Carbonic but there has been considerable difference of opinion as to just what portion of the Carbonic it represents, though the weight of opinion has been in favor of its age being Pottsville. Very recent field studies by Messrs M. R. Campbell! and David White are regarded by them as definitely establishing its Pottsville age. It is still doubtful, however, as to what part of the Pottsville it repre- sents. It may be the equivalent of either the Connoquenessing or of the Sharon. If it be equivalent. to the Sharon, the few feet of overlying shale represent the Sharon shale and the thin coal bloom the upper Marshburg coal. If it be the Connoquenessing, the overlying shale and coal belong to the Alton or Mercer coal group. Detailed work to the south and west will be necessary to settle this point. RECONNAISSANCE A reconnaissance was made southward into McKean county, Pa. and then westward on both sides of the state line nearly to the western edge of Warren county, Pa. Wolf creek conglomerate. South of Ceres the Wolf creek con- glomerate is well developed along King’s run, being in places fully 20 feet thick but weathering into pieces a few inches to a few feet thick. It dips under stream level a short distance north of Glenn postoffice. West of this point on the road to Eldred it appears at the upper fork of Newel creek and is again seen on the road just south of the upper fork of Barden brook, — whence it may be traced to Eldred where it outcrops 120 feet ~ 1 Personal letters from Mr M.

It is represented in the Dennis well at Bradford by part or all of the 35 feet of sandstone with base at 1620 feet above tide. West of Bradford it is not satisfactorily identified. It probably loses its character even as a sandstone and soon entirely disappears westward. : Salamanca conglomerate. No traces of the Salamanca conglom- erate were found south of Ceres or near Eldred. In the Dennis well at Bradford it is represented by the 23 feet of sandstone with “a few pebbles,” having its base at 1817 feet above tide. West of Bradford it is found up Marilla creek and west of Marilla summit it occurs on Corydon creek. It is again found west of the Allegheny river both in Pennsylvania and south of Steamburg in New York and from its elevation, its position in the section and its lithologic character as well as by its tracing westward, the writer concludes that it is the same as the Pope Hollow conglomerate, which may be traced south from Pope Hollow past Fentonville and Russellsburg by exposures at inter- vals along either valley wall of the Conewango to the Asylum quarry at North Warren. It may be traced westward up Rhind’s run by numerous exposures to a point on Jackson’s run about 2 miles east of Chandlers Valley. All exposures from here to Sugar Grove are covered with glacial till but it is quar- ried a short distance west of Sugar Grove, is found just above the mouth of the Lottsville well no. 14 and may be traced at intervals along the Little Brokenstraw valley northward past Grant station till there can be no doubt of its being the Panama conglomerate. Tracing it southward from Lottsville it passes about 225 feet beneath the Wrightsville conglomerate at Wrightsville and is doubtless the pebbly sandstone found “about 100’ from the surface” in the Rocky Hollow well? about a mile northeast of Wrightsville. It seems probable that far- ther south this Salamanca-Pope— Hollow-Panama conglomer- ate may be the same as the third Venango oil sand if that sand has a northward representative at all.

Wrightsville conglomerate. The Wrightsville conglomerate can not be identified with the Panama, but lies about 225 feet higher in the section. It seems reasonable to suppose that it is the equivalent of the Venango first sand as is believed by Lesley, though no attempt was made by the writer to trace it to a connection with that sand.! Olean and Subolean conglomerates. The Olean conglomerate is found on Mount Raub near Bradford and occurs on the hills south of Bradford decreasing gradually in elevation till it is last exposed in the Buitfalo, Rochester and Pittsburg Railway cut just north of Bingham station as an irregularly bedded sandstone. Here it dips under the plateau surface. No exam- ination was made of the region south of the divide where it doubtless reappears. The Olean conglomerate and the She- nango conglomerate and shale are traceable westward across Warren county. All occur on Quaker hill and at Pike’s rocks and elsewhere. The Olean appears at Miller’s rock but the Shenango seems to have been cut out there just as its equiva- lent, the Knapp formation, has been near the head of Irish brook and elsewhere as previously noted. Local pebble beds. During the reconnaissance locally devel- oped pebbly beds usually only a few inches in thickness were found at several points. These thin pebbly beds occupy no definite horizon but apparently may occur anywhere in the Cattaraugus or Oswayo formations. In no case was any one of them found to be persistent or to possess any stratigraphic importance. They were revealed by chance in some unusually good exposure in a railway cutting by the roadside, or along a stream bank and would ordinarily have entirely escaped observation. It is possible that at some point in the region 1for the opinions of the geologists of the second Pennsylvania survey on the correlations of the various members mentioned in the preceding paragraphs see White, I.

Fucoidal remains in the shape of vertical tubes piercing the sandstone or conglomerate layers of the Salamanca are specially characteristic of that horizon and in its north- © eastern portion were often used as an aid in its identification, though in all cases of doubt reliance was placed in its inverte- brate fauna. Southwestward in Warren county, Pa. while vertical fucoidal remains are still often very prominent in the Salamanca, they also occur at other horizons and hence if they may be used at all in that region as an aid in identification, it must be done only with a recognition of this fact in mind. COLUMNAR SECTIONS A few columnar sections selected at considerable intervals over the region are added in order to give some idea of the general stratigraphic succession in the region. They are ne- cessarily veneralized somewhat in the representation of thin beds. The concealed intervals are in most cases almost cer- tainly shales but in the sections are left blank. In section C pieces of the Wolf creek were found loose on the surface up to the level indicated by the displaced blocks, and the same thing is true of the Salamanca in section E. The thickness of the two thin limestone layers in the basal part of the Oswayo in section F is much exaggerated. In some cases the interval represented as being red shale consists of red and green shales interbedded in very thin layers. The purple or chocolate col- ored shale beds of the Chemung are seen in sections B and D. Eastward from B the Salamanca conglomerate lenses out, and ‘in B the Subolean conglomerate — though probably not con- glomeritic in this particular section— had been eroded before the deposition of the Olean. Finally, the writer wishes the conclusions that have been reached as to correlations in McKean and Warren counties to be recognized as ones based on a reconnaissance in a region where such work is beset with many difficulties. It is believed, however, that detailed work will only confirm the conclusions reached. FOSSIL FAUNAS OF THE OLEAN QUADRANGLE BY CHARLES BUTTS In pursuance of instructions received from the state paleon- tologist, the fullest possible collections of fossils were made from nearly every fossil-bearing outcrop on the quadrangle, including 259 stations. The analysis of the fossil faunas thus collected reveals their distribution according to the accompany- ing lists and seems to warrant the division of the strata into several zones, whose positions in the general stratigraphic succession are exhibited in the following columnar section. A few feet of shale exposed in the deeper valleys near the north- ern margin of the quadrangle are not shown in the section, as no collections were made from it. These zones correspond with Mr Glenn’s divisions as follows: Zone 2 is the Olean conglomerate, zone 3 is the, Oswayo shales and Knapp beds, zone 4 is the limestone layer, zone 5 is the interval between the limestone layer and the top of the Sala- manca conglomerate, zone 6 is the Salamanca conglomerate, zone 7 is the interval between the Salamanca and Wolf creek con- glomerates, zone 8 is the Wolf creek conglomerate, zone 9 is the interval between the Wolf creek conglomerate and the top of the chocolate shales, zone 10 is the chocolate shales and the quarry sandstones, zone 1i is the interval between the quarry layer and the Cuba sandstone, and zone 12 is the latter bed. On comparison of the zonal lists, it appears that there is a gradual disappearance of species on passing upward through the strata without the appearance of any new elements till the horizon of the Wolf creek conglomerate is reached. The zones below this horizon are therefore based on this disappearance of species at certain horizons, which gives rise to a slightly different facies to the overlying fauna. The zones do not coin- cide with the vertical range of some one or more characteristic species having definite upper and lower limits. Thus, so far as my collections show, Orthothetes chemungensis does not pass above the top of no. 11, Athyris angelica disappears at the top of no. 10, while at the top of no. 9 all but nine species disappear, and their places are taken in the next zone, the Wolf creek conglomerate, by new genera and species. REPORT OF THE STATE PALEONTOLOGIST 1902 991 ‘This important faunal change with the incoming of the Wolf creek conglomerate, taken in connection with the fact that on stratigraphic grounds, the equivalent of the Waverly of Ohio, of Subcarbonic age, is pretty certainly present in this quad- rangle, and in connection with the fact that the fauna of the conglomerate and higher beds contains a small Subcarbonic ele- ment, would indicate that the bed might be provisionally adopted as the base of the Subcarbonic in the quadrangle. Of the 128 species collected, 60 species occur below the Wolf creek conglomerate only, 59 species occur above the same horizon only, and nine are common. Of the 59 species occurring above the conglomerate, seven species can be referred to the Lower Carbonic. These are Ctenodus flabelliformis, Gyracanthus sherwoodi, Oehlertella pleurites, Orthothetes crenistria, Glossites (Sanguino- lites) amygdalinus?, Sphenotus aeolus? and Crenipecten winchelli. The stratigraphic significance of the abundant Ptychopteria fauna, so highly characteristic of zones § and 7, is not fully understood, as its stratigraphic rela- tionships have not been fully worked out. It must be admitted that the positive evidence is scanty and in itself hardly sufficient to establish a boundary line between the Devonic and Carbonic at the base of the Wolf creek conglomerate, but in a case like - this, where the stratigraphic evidence warrants the conclusion that such a boundary line exists, this evidence seems sufficient to give it a provisional location. Further than this it would be hardly safe to go. If this location be not accepted, there seems to be no paleontologic. ground for such a boundary line at all below the Olean conglomerate. Of the remaining zones, no. 5 is almost barren of fossils, no. 4 is a thin limestone in which Camarotoechia allegania Williams, makes its advent. This species is specially abundant in no. 3 and highly characteristic of it. A few fragmenitary re- mains of a Camarotoechia and an obscure pelecypod or two were found in fragments of Olean conglomerate, hitherto supposed to be nonfossiliferous. The species of fossils found in and below the Wolf creek con- glomerate are all marine. The presence of Holoptychius and Bothriolepis scales in no. 7 would indicate fresh or brackish 992 NEW YORK STATE MUSEUM water deposits, but, in the midst of these, thin layers of ferru- ginous conglomeritic sandstones or lumpy mud rock bearing marine fossils occur. No fossils of any kind are found in the red shales of no. 7 and 5. The fossils from the top of no. 7 to the top of the section are all marine with the possible exception of some obscure impressions of plant stems, some of which appear to be calamites, occurring at the top of the Olean conglomerate. The most favorable localities for collecting in zones no. 11 and 12 are found in the quarries and ravines at Cuba and vicinity and near the mouths of streams entering Ischua creek from Hinsdale to Ischua. In the other zones the best exposures occur and the best opportunities for collecting are found in the quarries and railroad cuttings both north and south of Olean. The Wolf creek conglomerate however has yielded fossils only in loose material in the vicinity of Portville on Wolf creek and on the high hills in the northeastern part of Cuba township.

CLARKE The differing interpretations of the Olean section given by Professor Glenn and Mr Butts in the papers preceding, afford an excellent illustration of the discrepancy which often results from the two modes employed. This discrepancy pertains how- ever solely to the determination of a conventional boundary plane in sediments characterized by the uniformity of their succession. The sequence of events involves the independent construction of the lithologic or purely stratigraphic evidence and of the facts derived from the succession of faunas. Ina ereat thickness of arenaceous sediments carrying variable intermixture of clay, slight and oft recurring differences of texture are produced and these variations are so locally related to coastal contour and bathymetry, to tidal ebb and flow and to stream discharge, that sedimentary differences seldom hold true far away from a given section. In the Upper Devonic of New York this marine arenace- ous sedimentation prevails through a thickness of 2500 to 3000 feet. It has long been a subject of close study. By the con- struction of a large number of meridional sections from east to west through the lower or Portage division of this sedimenta- tion we believe that we have now arrived at an understanding of the proper correlation of sections which, in the actual suc- cession of sediments, differ fundamentally. Doubtless with the similarly close analysis of the Chemung beds we shall arrive at an equally clear understanding of the succession and lateral extension of sedimentary differences. If we have gained any lesson from the careful analysis of these earlier or Portage sedi- ments and their contents it is this, that in these shallow water deposits there is very little correspondence between the sedi- ments and the organisms that lived on them, that indubitably continuous sediments may carry, without necessary variation of texture, wholly different organic combinations at different places; that faunas shift, encroach on the provinces of others and retreat without concomitant change in the sedimentation. Hence a history of the events of sedimentation from which may be drawn the record of coastal alterations, of shifting coast lines and bars, and, in consequence of increased or lessened terrestrial are te ’ REPORT OF THE STATE PALEONTOLOGIST 1902 997 erosion, does not correspond with exactitude to the succession of events recorded by the dissemination of faunas and their internal changes of composition. Perhaps no more effective illustration of the discrepancy in these standards of classification could be brought forward than that of the Portage sandstone, an element in this series of arena- ceous deposits —a well marked stratum which at the east of this region contains a highly developed Chemung fauna, but westward carries no Chemung species whatever and still farther west changes its lithologic texture also. Some hundreds of feet of sediment under it in the east likewise carry a brachiopod fauna, while in the west that fauna is wholly replaced in equiva- lent and continuous strata. We could not therefore portray on a map the succession of faunas for the Portage or lower belt of these arenaceous strata, so that there would be any correspond- ence to a cartographic portrayal of the succession of sediments. So far as we now understand the Olean and Salamanca regions after the careful survey on which Professor Glenn has reported and from a long standing previous acquaintance with the rocks and their contents, it may be said that there is less probability of discrepancy in the deductions derivable from independent con- sideration of the stratigraphic and the paleontologic evidence be- cause the uniformity of sedimentation is unaccompanied by so pronounced differences in faunation. The most serious question involved in this survey so far as concerns the classification of the rock formations, is the con- struction of the Cattaraugus beds, the mass of chiefly red shales and sands with their included conglomerate lenses. To indicate the transitional character of these beds by employing as a pro- visional designation Devono-Carbonic, as was at one time sug- gested, is on the whole a makeshift satisfactory to no one. Hence Professor Glenn has preferred to admit them, for the time being, into the Devonic and to place the line of division between that and the Carbonic system at the top of these red Cattaraugus beds. . It seems important however to take note of the two considera- tions through which this provisional determination is reached: (1) a possible unconformity at the top of the Cattaraugus beds, (2) the assumption of continuity of these red beds with the. we 998 NEW YORK STATE MUSEUM Catskill sediments of eastern New York and the tacit concession of the Devonic age of the entire series of those deposits. With regard to the phenomena interpreted as evidence of unconformity I should not be disposed to contest Professor Glenn’s inferences but to emphasize the fact that these sand reefs constantly dis- play indications of deep decapitation due to shifting of bars and change of direction of currents, or a modification by heavy tidal flow on a shelving coast. Unconformities thus frequently exist which are no indication of unrecorded time. As to the second assumption I feel that we should be specially cautious in taking for proven that Catskill sedimentation even in the typical sec- tion of the Catskill mountains is restricted to Devonic time. The Catskill represents a peculiar phase of sedimentation wide- spread in northern latitudes during the Devonic. The Devonic continent was profuse in great lakes and coastal lagoons whose sedimentation was carried on under conditions so unlike those of the ocean, that causes which would disturb and qualify the latter could not affect the former. We know that at certain places within the continental edge this sedimentation did con- tinue through the Devonic and endured till after the appear- ance of Carbonic faunas. Hence a certain part of Old Red sedimentation is in some instances postdevonic and may be so in New York; indeed in face of the paleontologic evidence I am very strongly of the conviction that it is so, and that the Cat- taraugus beds themselves supply the required proof of this fact. It is not a new suggestion that the upper stages of the typical Catskill are postdeyonic; the restudy of this Catskill area which is now proceeding may give us new light on this point and though it would be the unexpected to find transgression of the Subcar- bonic fauna extending into this lagoon area so far to the east, by some other criteria it may be practicable to affirm this dis- tinction. Time must also elapse before assertions can be made as to whether the Catskill strata of eastern New York are or any part of them is continuous with the Cattaraugus beds of Allegany and Cattaraugus counties. The paleontologic evidence thus far derived from this section and summarized by Mr Butts, indicates one fact with emphasis, that is, the one substantial change in the succession of organic assemblages occurs with the incoming of the Wolf Creek con- REPORT OF THE STATE PALEONTOLOGIST 1902 999 glomerate, at the base of the Cattaraugus beds. Here Carbonic types appear, a new fauna is introduced and without attempt- ing to analyze again the time values of the various components (I have already discussed this point in my report of last year, op. cit. p.524) it is enough to add that while the withdrawal of a large part of the Devonic fauna is concurrent with this new arrival, it is altogether to be expected that certain Devonic types survive. It will not do to state this condition as merely an intermixture of Carbonic and Devonic organisms, a charac- terization easily made and which would dismiss these beds as “transitional” but it is rather the fact of a new arrival in the field while survivors of the old faunas or superstitial species still endure. The condition is normal for the process of replace- ment of one fauna by another. It matters little if among the superstitial species one remains so characteristic everywhere of the later Devonic as Spirifer disjunctus; for not alone in New York does this species transcend the limit of the Devonic and enter the Carbonic. With proper regard for such modifica- tions as additional evidence may require I am disposed to the conviction that in placing the dividing line between Deyvonic and Carbonic at the base of the Cattaraugus beds, as is done on the geologic map, we have the support of the most direct evidence. STRATIGRAPHY OF PORTAGE FORMATION BETWEEN THE GENESEE VALLEY AND LAKE ERIE BY D. DANA LUTHER With stratigraphic map Genesee valley The Portage formation received its name “frdém its superior development along the banks of the Genesee river in the dis- trict formerly included in the town of Nunda, now Portage,” Livingston co. The Genesee river is a northward-flowing stream, rising just over the Pennsylvania line and completely traversing the State to Lake Ontario. About 214 miles south of the north line of this town the valley through which the river has flowed northward for 50 miles or more, ends, and the stream between ver- C h ~ — . . eRe tical cliffs 200 feet in hight enters a nar- row rock gorge, plunges over three cascades 34E Middlesex black shale Tespectively 76 feet, 110 feet and 66 feet high, with rapids above, below and between them, and descends about 350 feet in 2 eo miles, and 30 feet more to the north line of blue eray Portage township; so that, including 187 concretions feet of sandstone above the river at the upper end of the gorge and 75 feet for the Styliola southward dip, about 635 feet of strata are . exposed in the district referred to.

In this distance the river descends 100 feet, and the southward dip of the strata is 32.5 feet a mile. The Portage town line is 9 miles south of the mouth of the gorge at Mount Morris, and the dip therefore adds 292 feet to the thickness of the exposed strata and gives a total of 392 feet, of which all but 65 feet are included in the “ Portage group ” as described and limited by Prof. Hall. The Styliola or Genundewa limestone of the Genesee shales, which is 82 feet above the top of the Hamilton shales in the ravine of Little Beards creek at Lei- eester, 3 miles north of the mouth of the gorge, is exposed in the banks near the west end of the Western New York and Pennsylvania Railroad bridge at Mount Morris, and, with a few feet of black light and dark shales with flags blue and slates below it, is the lowest rock ex- lar geese posure on this section of the river. About 65 feet of typical upper Genesee shales overlie the Styliola limestone and are exposed at the east end of the cov- light shale ered highway bridge at the mouth of the gorge, where the spheric concretions and characteristic fossils of this horizon are common. At the top of these bluish black shales there are a few lighter colored layers, some clayey, others slightly arenaceous, distributed through about 3 feet of _,~t°- 2 Section in Buck run ripe at Mt Morris, above darker shales.

Stations 4, 5 band, hardly noticeable here, but fully developed farther east, has the sedimentary characteristics of the Portage shales and flags and contains a few fossils from both the Genesee and the Portage faunas. — Overlying these passage beds there are 32 feet of densely black and bituminous slaty shales in which plant remains are black shale Cashaqua shale 1002 NEW YORK STATE MUSEUM common, and a few fish scales and plates have been found, but otherwise they are generally barren. A few small Lingulas (L.spatulata, L. ligea) found at the mouth of Pike creek on Lake Erie are the only fossils collected from this horizon, and they seem to belong to the species found in similar black Shales higher in the formation. This bed of black shales has quite the same structure and appearance as other black bands in the Portage section. Above this horizon there is no recurrence of the Genesee fauna. The bottom of the passage beds immediately below the black band is therefore taken as the base of the Portage formation, and the stratum of black shales above has been designated by the state paleontologist as the Middlesex shales. Middlesex black shales. This bed decreases slightly in thick- ness toward the west, but is thicker and quite arenaceous in the Dansville and Naples valleys. It is exposed in the cliffs on both sides of the Genesee river, from the mouth southward for a little more than two miles, the dip bringing it down to the water level on the south side of the “ Hogsback.” Near the top, after several alternations with lighter layers in a few feet, these shales are replaced by light bluish gray, and olive shales, “soft argillaceous rock of a green color” (Hall). Cashaqua shales. This mass is 165 feet thick, and was termed by Hall the Cashaqua shales because of their excellent exposure in detail in the gorge of Cashaqua creek, 5 miles east of the Genesee river. The general color of this shale in weathered exposures is a very light olive; but, when freshly excavated, it is medium dark bluish gray with frequent intercalations of darker or black layers of varying thickness, sometimes so thin and frequent as to give the rock a straticulate or laminated structure. In the section along Cashaqua creek there are a few thin flags in this horizon, and they increase in number toward the east. ‘They are hardly noticeable in the Genesee river section.

Fossils are not abundant in any part of these shales, but a few specimens occur in the lower part; they are much more common in the upper part, where they are found in con- siderable numbers in a few thin layers of shale and also in the concretionary layers and the separate concretions. A row of concretions, usually a foot or more in diameter at the top of these shales and exposed in the river section, rests on a calcareous layer 14 inch to 2 inches thick that is composed of fossils, many of z=. sandstone which are finely preserved.

Rhinestreet black shales. As the lighter shales decompose more rapidly than the black, the latter predominate in the coloring and, specially in old exposures, give to this division the appear- = ance of being a homogenous bed of black top of Upper shale. The division has therefore been termed the Rhinestreet black shale from Stimaee!, “al exposure in the town of Naples.

Hatch flags and sands. Above the Rhinestreet shales are light and dark shales, 88 feet, in layers of varying thickness from a fraction of an inch to several feet, and with a few thin flags of fine blue sandstone distributed at irregular intervals. A row of symmetric concretions, from 1 foot to 14 feet in diameter lies at the base of this subdivision, and many others of various sizes and shapes are scattered through it and serve to distinguish it from the overlying beds. Fossils are rare except in a few of the lighter layers, but the beds are more fossiliferous toward the east. Above there is a band of flaggy sandstones, 6 feet thick, ex- posed for several miles in the cliffs on the east side of Smeky hollow and the Gardeau fiats. It comes down to the river level opposite the “Five Corners road,” 1 mile north of St Helena. At this point the cliff above the flaggy band shows 115 feet of shale in which no sandstones appear except about 10 feet of thin flags. A large proportion of this shale is dark and slaty, and the remainder is quite ferriferous, consequently the general aspect of the weathered face is very dark, almost black, and rusty. Fossils are almost entirely absent. In the escarpment at the east end of the St Helena bridge 60 feet of these shales are exposed and are overlain by 25 feet of flags and soft sandstones that are separated from each other by thin layers of hard blue shale. This arenaceous bed is thicker and proportionately sandier toward the east. In the Dansville, Springwater and the Naples valleys it contains fossil sponges, and at the last place many brachiopods and other fossils, and marks the upper limit of the normal Portage fauna, and is there known as the Grimes sandstone. At the mouth of Wolf creek this bed is overlain by shales and flags 110 feet thick, in which dark or black shales still pre- dominate. It is exposed in the rock wall beneath the “ Table rock ” above the mouth of Wolf creek near the south road from St Helena to Castile, and in the gorge southward between the 1006 “Twin Hogsbacks ” to the Lower falls.

Fossils are quite common in the soft light shales between the two sandstone layers. There are 49 feet of strata, mostly shales, between “Table rock” and the horizon of the bottom of the Middle falls, and 118 feet in the face of the Middle falls, in which there is a much larger proportion of sandy layers. Fallen blocks of the sandstones from the vertical cliffs at and below the falls are almost entirely barren, but Aulopora and a few brachiopods, of species com- mon in this horizon farther east, were found, but these probably came from some of the sandy layers above. There are 19 feet of flags and shales exposed between the top of the Middle and the horizon of the bottom of the Upper falls.

In the 262 feet of strata between the “Table rock” and the top of the Gardeau beds, changes in the sedimentation are very frequent. Layers of black, blue black, blue gray and olive shales, and blue or olive sandstone, usually but a few inches thick, succeed each other in irregular order, but there is a noticeable increase upward in the sandy layers, and in the face of the Upper falls they equal or exceed the shales, though there are no heavy compact layers.

The Portage sandstones consist of 187 feet of strata exposed in the walls of the gorge above the Upper falls, from the top of the 4 foot shaly layer at the crest to the top of the cliff on the east side south of the high railroad bridge. Except a bed of hard blue shale, containing calcareous nod- ules, 2 feet thick, 12 feet above the base and a layer of similar character 6 feet thick and 52 feet higher, the entire formation is com- posed of light bluish gray sandstone in ae layers from 2 feet to 10 feet thick, separated by 1% inch to 6 inches of shaly matter. shales In some of the upper layers the sand- stone is compact, durable and valuable fagsand shale for building purposes. Other layers are schistose along the laminae, and a few are shaly and friable. Large ob- scurely defined concretions occur in one or two of the more calcareous layers, but they are few. The two beds of shales and the shaly partings between the layers contain a very few fossils, all like those below. _F ie. 6 Section at Long Beards In the sandstones Fucoides ver-_ “ffs.

The fossiliferous layers are exposed in the north bank of the. ravine of Wiscoy creek 14 mile above the village of Wiscoy, and below it are 137 feet of strata, many layers of which are black shales and others are soft, light colored and clayey.

REPORT OF THE STATE PALEONTOLOGIST 1902 1009 The Wiscoy shales are also exposed in Scotts ravine 2 miles northeast of Fillmore and in several other ravines on the east side of the valley opposite Rossburg. Naylor’s quarry near the Erie Railroad station at Castile shows a small section in the Wiscoy shales in which Manticoceras rhynchostoma is common at one hori- zon in the soft sandy shale. Toward the east the Wiscoy shales are more arenaceous, and the horizon is one of laminated or flaggy olive sandstones in which Chemung brachiopods are abundant. Long Beards riffs sandstone. There are no rock exposures along the river between the Genesee Bluestone Co.’s quarries ‘and Long Beards riffs, 14 mile south of Fillmore, a distance of about 8 miles. At this point an uneven layer of hard calcareous sandstone makes a low cascade in the river and is exposed on both sides of the channel. An escarpment on the east side of the riffs shows 10 feet of shales and flags below the principal layer, and 3.5 feet of shales with a few even layers of sandstone above it. This heavy layer and another 4 inches thick 25 feet higher contain Chemung brachiopods abundantly. — This horizon is the lowest in which Chemung brachiopods were found in place in the Genesee river section. Estimates based on such measurements as could be made, show it to be about 167 feet above the top of the “ Portage sandstones ” as exposed at Portageville. Résumé The Portage group, as exposed in the gorge of the Genesee river, which is the type section, includes between the top of the shales bearing a distinctively Genesee fauna at the mouth of the gorge and the top of the Wiscoy shales at Long Beards riffs, 1207 feet of strata. Marked changes in the character of the sedimentation make the following subdivisions of these beds recognizable, beginning at the base of the section: 1010 NEW YORK STATE MUSEUM oe i’ Passalve’ Shaler so.

Oatka valley section That part of the Oatka creek, or Warsaw valley, in which the bed rock belongs to the Portage formations, lies about 10 miles north and west, and 300 to 400 feet higher than the exposures of the same horizons in the Genesee river section, and is about 18 miles long. The Portage sandstones and the top of the Gardeau flags are exposed at Oatka falls near Rock Glen, but there are no other exposures of Portage strata in the channel of the river. There are many ravines, some of which are very deep, in the sides of the valley, and they afford good exposures, that together, vir- tually cover the entire Portage section. The following are some of the most important of the expos- ures, beginning at the north. In a small ravine on the west side, about opposite the village of Pearl Creek, the little brook flows over a cascade 15 feet high, of which a compact layer of the Styliola limestone of the Genesee shales forms the crest. Above the cascade about 50 feet of bluish upper Genesee shales are exposed, and a few feet of the Middlesex shales of the Portage formation outcrop above them, and rest directly on the Genesee shales. The transition bed is not perceptible here. In the ravine at Wyoming village about 50 feet of the upper part of the Cashaqua shales are exposed. They are mostly light bluish gray or olive and very soft. Calcareous concretions and concretionary layers are frequent. Fossils are quite common. Farther up the ravine and about 14 mile from the village, 40 feet of black shales in the horizon of the Rhinestreet shales are exposed, and above them, about 30 feet of alternate layers of light and dark or black shales. 1012 NEW YORK STATE MUSEUM The upper Cashaqua beds are also exposed along a small brook that comes into the valley on the east side 14 mile south of the Wyoming railroad station. In a ravine on the west side of the valley, 2 miles south of Wyoming, 150 feet of the Hatch shales are exposed, and in an- other ravine about 2 miles farther south 120 feet of the strata next higher in the section. A flaggy band that occurs near the top of the exposure in the latter ravine is probably in the horizon of the Grimes sand- stones, but it is proportionately less arenaceous. In the Fall brook ravine 14 mile southwest of Warsaw there are 236 feet of shales and flags exposed below the Erie Railroad bridge. They are all in the horizon of the middle portion of the Gardeau beds, or that of the Lower and Middle falls at Portageville. Gibson’s glen is a ravine on the west side of the valley 214 miles south of Warsaw, that ends in a high fall, above which the basal layers of the Portage sandstones outcrop. About 150 feet of flags and shales are exposed below the sandstones. A thin layer of soft shale at the mouth of the glen contains many flattened concretions, in some of which finely preserved fossils occur. A few fossils occur in all parts of the Gardeau division in this valley, but they are much more common near the bottom and toward the top than in the middle of it. In the ravine of Oatka creek, at and below the falls near Rock Glen, about 100 feet of Gardeau flags and shales are ex- posed and the lower layers of the Portage sandstones outcrop along the stream above the falls. The old quarries of the Warsaw Bluestone Co. on the west side of the Erie Railroad, near the village of Rock Glen, show about 50 feet of the lower part of the Portage sandstones, and the upper part outcrops along the little brook southw est of the quarries. piankinaiiad REPORT OF THE STATE PALEONTOLOGIST 1902 1013 Stations in the Oatka valley 47 Ravine on west side opposite Pearl Creek.

Tonawanda valley section The western part of Wyoming county and southeastern part of Erie county is an elevated region in which the higher ridges and hills are 1500 feet to 1700 feet A. T. It is in the drainage area Of Lake Erie and the Niagara river, and the streams flow toward the north and west, cutting a large number of valleys and deep ravines across the Portage rocks, in their rapid descent cof 600 feet to 900 feet to the broad level area that borders the lake. The valley of Tonawanda creek is the most easterly one. It extends southward from Attica for about 10 miles, is 14 to 1 mile wide, and its sides are steep slopes, in which several small streams have cut small gullies that expose the rocks. The rock section begins along the Tannery brook in the northern part of the village of Attica, where there is a long exposure of the upper Genesee shales. At the cascade 10 feet high, 144 mile above the old tannery, these light shales are succeeded by the black Middlesex shales. 1014 NEW YORK STATE MUSEUM The exposure continues a few rods up the stream, but the con- tact with the Cashaqua shales is covered. The Middlesex shales are also exposed in the bed of Tonawanda creek below the milldam in the village. The Tannery brook is crossed by the Erie Railroad 1 mile west of the village, and about 50 rods south of the railroad there is a good exposure of the Cashaqua beds along the east branch of the stream. Fossils are quite abundant here in the shales and in the numerous concretions. The top of the Cashaqua shales and the lower part of the Rhinestreet shales are exposed a few rods farther south. A thin layer of pyritiferous black slate near the contact line contains Bactrites, Orthoceratites and a few other fossils beautifully preserved in pyrite. At Sierks station, 4 miles south of Attica, the upper part of the Rhinestreet shales is exposed in the bed and sides of Tona- wanda creek and the alternating layers of light and dark shales of the base of the Hatch division on the hillside and along the railroad south of the depot. Some fossiliferous layers of light shale occur near the top of the exposed section and a row of large concretions a few feet above them. At Varysburg, 8 miles south of Attica, there is am exposure of 25 feet of Gardeau flags and shales, with concretions and a few fossils, in the banks of Tonawanda creek, below the mill- dam in the village. With the exception of about 25 feet next above this exposure, that are covered, the Gardeau section may be seen in the bottom and sides of Stony brook, that comes in from the east through a deep ravine, and joins Tonawanda creek above the dam. This is a fine exposure, and it ends at the base of the Portage sandstones. A small gully on the steep hillside west of Varysburg is crossed by the Buffalo, Attica and Arcade Railroad, at the altitude of 1240 feet A. T. Above the bridge about 250 feet of Gardeau flags and shales are exposed. A thin sandstone about level with the bridge contains fossil sponges. For 140 feet above this layer the beds are generally shaly, but flags and thin sand- REPORT OF THE STATE PALEONTOLOGIST 1902 1015 stones are frequent, and some of the shaly layers are quite sandy. A few of the sandstones are a foot or more thick and hard. The Portage sandstones are exposed in the upper part of the ravine to the brow of the hill. Some of the layers are compact and heavy and have the same appearance as in the Genesee river section, but most of the bed is softer and laminated, and some parts are quite shaly. The thickness seems to be but about 75 feet, but the lower limit is not well defined. The bed of soft olive and black shales that succeeds the Portage sandstones is exposed above the crest of the hill in a short shallow gully. The Gardeau beds and the sandstones are also exposed in a similar ravine, 2 miles farther north, where the sandstones have been quarried for railroad purposes. On the east branch of Tonawanda creek about 114 miles above the forks and 5 miles south of Varysburg, a layer of calcareous sandstone outcrops in the bed of the stream for a few rods, and the same stratum appears in a small quarry 14 mile northeast. It contains great numbers of small frag- ments of brachiopods, nearly all of which are too minute to allow identification of the species. It bears a very close resemblance to the Long Beards riffs fossiliferous layer; it is the lowest horizon in which brachio- pods were found in this section; as it is at the proper altitude, it is doubtless the same stratum, or, at least, in very nearly the same horizon. On the south side of the Erie railway bridge at Griswold, 6 miles west of Attica, the Styliola limestone is exposed in the bed of Murder creek. It is 18 feet above the top of the Hamil- ton beds as exposed in the east bank of the stream 50 rods north of the depot, and is overlain by 13 feet of typical upper Genesee shales, above which are the black Middlesex shales. A long flat exposure of the Cashaqua shales is in the bed and sides of the stream to the falls; including 5 feet of alternat- ing light and dark layers at the bottom and 12 feet of the same character at the top, they are 77 feet thick here. 1016 NEW YORK STATE MUSEUM At the falls and in the ravine above, about 100 feet of black Rhinestreet shales are exposed. A row of very large septaria, occurs in the black slates 28 feet above the top of the Cashaqua shales. The Middlesex shales and the base of the Cashaqua shales are exposed in the bed of Ellicotts creek, 114 miles west of the Erie Railroad station at Darien. The bottom of the Cashaqua shales is level with the rails on the bridge. This is the most northern exposure of Portage strata in this State. On Cayuga creek an outcrop at Iron Bridge Mills shows the Styliola limestone and 12 feet of Upper Genesee blue black shales above it. At Cowlesville, 2144 miles south, there is a large exposure of the Cashaqua shales in the cliffs along the stream, and the Rhinestreet shales with many large septaria outcrop almost continuously below and above Folsomdale. At and above the forks at Cayuga creek, 3 miles south of Folsomdale, the top of the Rhinestreet shales and about 100 feet of blue shales, in which thin layers of black slates and a few flags are intercalated, are exposed. _ On Buffalo creek the upper part of the Cashaqua shales is exposed in the escarpment along.the west side of the stream below the bridge at East Elma. Fifteen feet of black slates crop out 1144 miles up the stream, and at Porterville 100 feet of the Rhinestreet shales are exposed, in which two rows of very large septaria, separated by 35 feet of black slates, occur. Some of the septaria are 8 feet in diameter and 2 to 2% feet thick. At Johnson Falls, 7 miles up the valley southeast from Por- terville, a small creek comes into the valley from the east over a high cascade and through a short but deep ravine. There are 62 feet of Gardeau shales and flags exposed below the falls, and 144 feet in the face of the cascade and at the top. The beds are principally soft bluish shales with flags and thin sandstones, that are more frequent and thicker toward the top. REPORT OF THE STATE PALEONTOLOGIST 1902 1017 The soft layers contain the common Portage fossils in small numbers, and crinoids and Aulopora also occur. A layer of sandstone 2 feet thick, about 40 feet above the bottom of the cascades, contains fossil sponges. The horizon is very nearly the same as that in which sponges occur at Varysburg. At the top of the falls a layer of compact blue sandstone 5 feet thick is overlain by 4 feet of shales, that are succeeded by another layer of gandstone like the one below and 10 feet thick. The strata next above are covered, but black shale is exposed slightly a short distance up the stream. These sandstones are in the horizon of the Portage sand- stones of the Genesee river section. They are near the surface over a large area in the town of Sheldon and outcrop in many places. They also outcrop frequently on the west side of the valley south of Johnsons Falls for 5 or 6 miles, to Java Village, where 8 feet of the upper bed are exposed on the upper side of the bridge over a small stream that comes in from the east through a deep ravine. The sandstone is here succeeded by 15 feet of black shale, next above which there are 145 feet of soft blue and olive Wis- coy shales with thin bands of black slates and a few thin flags. In the lower part of this section the rock is quite calcareous, and there are many concretions and concretionary layers. The upper part is more sandy. Buchiola speciosa and Palaeotrochus are common, and other Portage species occur in the lower soft shales. A layer of calcareous sandstone, 1 foot, 8 inches thick, forms the crest of a cascade 15 feet high and is 160 feet above the sand- stone at the mouth of the glen. It contains many small fragments of brachiopods, very few of which are large enough for identification of species. This stratum is in every way like the fossiliferous layer at the top of the Tonawanda creek section, the outcrop of which is 5 miles east of this point, and it is without doubt the same. It is succeeded by 10 feet of softer, flaggy and shaly sand- stone and 85 feet of hard blue shales in which there are a few even flags. 1018 NEW YORK STATE MUSEUM The only fossils found were a few brachiopods scattered through the shale and several impressions of Liorhynchus on the lower surface of a sandy layer. On the east side of the valley of Cazenovia creek, 114 miles north of Holland, the sandstones of the Portageville horizon are exposed in an old quarry and other places near the rail- road, and the black shales that succeed them may be seen in the bed of the stream in the village. In a small ravine on the east side of the valley a little north of the railroad station, there is an exposure that begins about 50 feet above the sandstones, in which there occurs, 100 feet above the bottom, a layer of calcareous sandstone a foot or more thick, of the same character as the one in this horizon in the Java Village ravine, except that no fossils were found in it. A loose slab, fallen apparently from but a few feet higher, contained Liorhynchus, Ambocoelia umbonata and Orbiculoidea. | Stations in the Tonawanda creek valley 25 Along the Tannery brook, 1 mile west of Attica.

Lake Erie section The exposure of Portage strata on the shore of Lake Erie begins in the cliffs on the south side of the mouth of Eighteen Mile creek in the town of Evans, Erie co. and, through broken» by many short stretches of sandy or gravelly beach, is almost continuous for 45 miles to the northwest corner of the town of Westfield, Chautauqua co. 8 miles from the Pennsylvania line. But three of the subdivisions that can be made in the Portage formation in the Genesee river section can be identified here by the character of the sedimentation. The Middlesex, the Cashaqua and the Rhinestreet shale are much alike in both sections except as to thickness, but above them there is in the lake section a thick mass of shales, light colored and more or less calcareous at places, black and bitu- 1020 NEW YORK STATE MUSEUM a minous, in which flags or sandstones are absent from all the lower part, rare in the middle, and are a considerable portion Rhinestreet black shale Cashaqua shale Middlesex black shale Styliola limestone Moscow shale Encrinal limestone Tia. 8 Cliff ‘section oppo- site Hotel Mortimer, Lake Erie shore near North Evans. Station 50 of the sediment only at the very top of the section. Calcareous concretions and _ concre- tionary layers are of frequent occurrence in all parts of the section. Fossils are common in the lower and the upper beds but are very rare in the middle ones. The fauna is composed al- most entirely of cephalopods, gastro- pods and lamellibranchs. Chonetes lepida occurs occasionally in the Cashaqua shales, a few Lingulas in the black slates and a small Productella near the top of the group were the only other brachiopods found. In the exposure in the south shore cliffs, 144 mile south of the mouth of Eighteen Mile creek, the Styliola lime- stone is separated by 1 foot of dark shales from the top of the Hamilton shale. This limestone is 6 inches thick and inclined to be shaly, but is more compact and 12 inches thick where it comes down to the lake level 114 miles to the south. It is overlain by 11 feet of characteristic Upper Genesee _ shales, that are succeeded by the black Middle- sex shale, which is here but 8 feet thick. The Cashaqua shales, also exposed in the cliff, are 32 feet thick, and consist of 24 feet of very light colored clayey shales, and above these 8 feet of light and dark shales. Concretions are common throughout the formation. The upper part of the cliff is in the horizon of the Rhine- street shale, and the rock is all black slaty shale. At the mouth of Pike creek 12 feet of Tlamilton shales, the Genesee shales and the Middlesex are exposed. REPORT OF THE STATE PALEONTOLOGIST 1902 1021 The base of the Portage formation is 12 feet above the lake level. Small Lingulas of two species occur in the black slates. The lower part of the Cashaqua shales is not exposed along Pike creek, but above the highway bridge, __. 60 rods from the lake, the upper part is well exposed in the bottom and sides of the channel. Fossils are common in the numerous concretions and some of the soft layers. The contact with the Rhinestreet shale dark shales is at the bottom of a low cascade, and ‘03 tap henteer about 15 feet of the succeeding black slates are exposed in the sides of the ravine.

Station 51 Impressions of goniatites are very common in the Casha- qua shales, and in the concretions also a small Loxonema. Buchiola speciosa is very rare, but a few other lamelli- branchs appear frequently. The shale in the softer layers has about the consistency of dried clay and the only hard layers 1022 NEW YORK STATE MUSEUM are calcareous and concretionary. Spherical concretions are numerous, and some of them are 1 foot to 3 feet in diameter. The dugway roads leading down to the bridge at North Evans were excavated in the black Rhinestreet shale, and all of this formation is exposed in detail in the bottom and sides of the Eighteen Mile creek gorge between North Evans and the Erie Railroad bridge, 4 miles to the southeast. It is 185 feet thick in this section and is composed principally of bitu- minous black shale, but there are several layers of bluish shale, some of which are 6 feet to 8 feet thick, and in these lighter beds there are many large septaria and beautifully Symmetric concretions. In two or three rows in the upper part of the band the septaria reach a diameter of 6 feet to 10 feet and are 2 feet to 4 feet thick. The lighter layers contain a few fossils like those found in the Cashaqua beds. The black slates are almost barren, except of plant remains, which are quite common. In the cliff at North Evans a small Lingula occurs in one of the lower black layers. These shales are exposed at several places along the lake shore on the north side of Sturgeon point and along the railroads in the vicinity of Derby. A concretionary layer 6 inches ge 8 inches thick, the upper surface of which is a scraggly mass of angular fragments of impure limestone, separated by thin seams of spar, like the sur- face of a fiat septarium but finer, is taken as the top of the Rhinestreet shale, the proportion of black shale above this hori- zon being less than the lighter. It is exposed under the Erie Railroad bridge over Eighteen Mile creek below Eden Valley and near Angola, and on the lake shore. The lighter shales that succeed the Rhinestreet shale are ex- posed in a small ravine that comes into the gorge of Eighteen Mile creek from the east about 60 rods above the Erie Railroad bridge. The section covers about 100 feet, in which there are many large and small spherical concretions and others that are oblong and flattened. Very few of them are septaria. This horizon is stratigraphically continuous with the Hatch shales and flags of eastern sections, but its lithologic characters have changed somewhat. REPORT OF THE STATE PALEONTOLOGIST 1902 1025 The same horizon is exposed in the cliff on the west side of the main ravine and in the creek bed below the highway bridge 14 _mile farther south. ; The scraggy layer at the top of the Rhinestreet shale outcrops at the lake level at Fox’s point on the south side of Dibble bay 21% i I le i Re il le ee, i Fic. 10 Section on Big Sister creek from Evans Cen- ter to Pontiac. nodular shale light blue and olive shale with thin black and concretionary layers light soft shales with large flat concretions light shales wit ; concretions light and dark shales wit concretions Station 52 miles west of Angola, and about 60 feet of the light shales next above it and several rows of the large concretions are exposed in the escarpments along the shore for a mile to the mouth of Mud creek. The rock exposure on Big Sister creek begins about a mile from the lake shore. About 50 feet of the Rhinestreet shale may be seen in the bottom and sides of the creek in the vicinity of Evans and southeastward to the escarpment on the north side of the Angola cemetery. At the foot of the south end of this low cliff the concretionary layer crosses the chan- nel, and it can be traced in the cliff, rising rapidly toward the north. Between this layer and a soft cal- careous sandstone 4 inches thick, con- taining many nodules of iron pyrites that is exposed in the cliff on the north side of the creek 20 rods above the Lake Shore Railroad bridge at Angola, there are 68 feet of light soft shales, in which there are a few thin, black layers and Several rows of flattened concretions, from 2 feet to 4 feet long and 8 inches to 12 inches thick, besides many smaller ones. Manticoceras rhynchostoma and other cephalopods occur, finely preserved in the concretions _and the shales contain a few lamellibranchs. This horizon is the same as that at the top of the previously described section on Eighteen Mile creek. It is also exposed 1024 NEW YORK STATE MUSEUM along Delaware creek a mile west of Angola and in the escarp- ments on the lake shore, north of the mouth of Mud (or Farn- ham) creek. Between the 4 inch sandstone in the escarpment at Angola previously referred to, and the top of the rock exposure at Pontiac there are exposed in the ravine of Big Sister creek about 100 feet of soft, light colored shales in which there are a few black layers, but no flags or sandstones. Altogether the beds are much like the Cashaqua beds, except that concretions are much less frequent, and most of them are quite small, but there are many concretionary layers from - 2 inches to 4 inches thick. These beds are also abundantly exposed in the quarries of the Buffalo Sewer Pipe Co., 14 mile south of Angola, and along the Lake Shore Railroad in the rock cut between the Delaware creek culvert and Farnham. A few low escarpments along the lake shore between the mouths of Mud creek and Cattaraugus creek are in the hori- zon of the upper part of the section on Big Sister creek. At.Pontiae there are two thin beds of light shale in which there are embedded great numbers of smail calcareous nodules or concretions that give the beds a pebbly structure. They are separated by 4 feet of light shales, in which the pebbles do not appear. A layer of black slate 2 feet thick is 4 feet above the upper pebbly layer. This horizon is exposed in the cliffs on the south side of Cattaraugus creek and a few feet above the water on the south side of the mouth of Silver creek. The black layer appears in the bottom and sides of Walnut creek, near the Emke flouring mill in the south part of the village of Silver Creek. There is an almost continuous exposure of upper Portage and lower Chemung strata along the channel of Walnut creek for more than 10 miles south from Silver Creek, the first 3 miles in a deep gorge. In this ravine next above the 2 foot black layer near the mill, there are 112 feet of shales, nearly all light colored except two dark beds each 11 feet thick. The bottom of the first is 15 ed REPORT OF THE STATE PALEONTOLOGIST 1902 1025 feet and the second 56 feet above the base of this section. These beds are equivalent to the upper part of Hatch flags and shales of eastern sections. Dunkirk shale. A third black band, the Dunkirk shale, similar in character to the Middlesex and the Rhinestreet shales, succeeds the 112 feet of lighter beds and is 55 feet thick. At the bottom there are 35 feet of densely black, slaty shales, like those in the other black bands and containing the same species of Lingula. The base of this shale is exposed in the cliffs on the south side of Dunkirk harbor and in the escarpments on the west side of Point Gratiot. The septaria are strewn along the beach 2 miles southwest in the vicinity of Van Buren point. The same beds are exposed in the bot- tom and sides of Silver creek under the high bridge at Hanover Center and in two large ravines near North Collins, and along the highway on the hill 1 mile east of Eden Center in Erie county. Above the Dunkirk shale light, soft shales again predominate, but layers of shales and flags black shale light shale black shale light shale black shale from an inch to severai feet in thickness occur very frequently, and con- cretions are common.

With stratigraphie map and sections BY AMADEUS W. GRABAU Introductory Becraft mountain, close to the city of Hudson, has been known to geologists since the early days of geologic study in the State of New York, and descriptions of it play an important part in the early reports on the geology of the State. In a letter dated Dec. 3, 1820, and .published in Silliman’s Journal for 1822?, Mr John P. Jenkins, of Hudson N. Y., gave a brief description of Becraft mountain. Hecallsit“. . . a solid mass of gray rock supporting a blue compact limestone; the upper strata of both rocks contain a great variety of petrifactions which have been described by Mr Eaton and others.” In 1823 Silliman described the “marble of Hudson,” which was wrought by Mr Charles Darling of that city. He considers it of high class, and similar to that of the Peak of Derbyshire. The “marble” is the Becraft limestone of Becraft mountain. Mather® in 1838 gives a description of the strata of Mount Becraft and of Mt Bob, which lies a little to the north, as well as their general structure, and states that the limestone of the mountains lies unconformably on the Hudson river slates. In 18404 he compared the strata of the Helderberg mountains with those of Becraft, considering them similar. In 1841° he again refers to Becraft, emphasizing the unconformity between the “nearly horizontal” Helderberg limestones, and the “ highly inclined ” subjacent Hudson river strata. In his final report, 1843°, Mather describes Becraft mountain, and gives three sections to illustrate the structure. The descrip- highest elevation on it is less than 500 feet above the sea. Structurally, how- ever, it is a section of a mountain range. All the localities may readily be vis- ited in a short walk from Hudson N. Y., where good accommodations may be obtained at the Worth house, or in private boarding houses. 2 Am. Jour. Sci. 1822. 4:33. ® Geol. N. Y. Ist Dist. 2d An. Rep’t. 1838. p.165, 166. ‘Geol. N.

REPORT OF THE STATE PALEONTOLOGIST 1902 1031 tion is largely a repetition of that of 1838. He recognizes three formations overlying the Hudson river beds, viz (1) the Water- lime group, including the Tentaculite limestone (Manlius), (2) the Catskill shaly limestone (New Scotland), and (8) the upper, Scutella, or Sparry limestone (Becraft). The Coeymans and Kingston were not differentiated from the limestones respec- tively underlying each, and the higher strata were not recog- nized. He determined the essential basin-shaped structure of the mountain, and the unconformity between the lowest bed of the series, and the underlying tilted and eroded Hudson river strata. This unconformity is depicted in his section 6, which furthermore illustrates with section 4, what he believed to be a series of tilted fault blocks. This structure was undoubtedly suggested by the numerous cuestalets which characterize the outcrops of the New Scotland, and to some extent the other beds also. The steep infaces or fronts of these erosion ridges and the surface slopes of their tops, which follow the dip, have -all the aspect of the corresponding faces of slightly tilted fault blocks [fig. 1, a, b]. Mather also gives a section of the south- east end of Becraft mountain, which shows the overturned strata on the east. Fig. 1 Diagram illustrating the detailed structure of parts of Becraft mountain: a, as in- terpreted by Mather; }, as actually existing. In 1846 Emmons! gave a section of the southeastern end of Becraft mountain, showing a conformable relation between the Hudson river and overlying waterlime. He also speaks of a mass of Calciferous sandstone supported by the Taconic slate. This refers probably to the hill of Burden conglomerate opposite the center of the eastern face of the mountain. In 1858 Rogers? mentions the unconformity at Becraft, which he states he discovered in 1887. He says: The lower Helderberg or Pre-meridian rocks are seen in hori- zontal stratification in the hill, while the Hudson river slates wa Agriculture of New York. 1846. 1:136. ?

Hall in 18591 expressed a doubt as to the reported uncon- formity between the Hudson river and Lower Helderberg strata, since ‘in Becraft’s mountain the strata of this age [Lower Helderberg and Waterlime]} le inclined aboye the Hudson river group, and there appears no positive evidence of their uncon- formability.” The most complete review of the literature of Mt Becraft and the neighboring region on both sides of the Hudson is given by Davis in his article on the folded Helderberg limestones east of the Catskills? From a study of-this region on the west bank of the Hudson, he concludes that the contact between the Hud- son river shale and the Waterlime is a conformable one, though he considers this conformity difticult to understand in view of the variation of the strata. In 1883° Davis published the first geologic map of Beecraft mountain and gave the first comprehensive account of its strati- graphy and structure. The map is accompanied by a number of cross sections, which give the main structural features of the range. He recognizes the Waterlime (Manlius) resting on the Hudson river beds and discusses at length the evidence for and against the unconformity between the two. While leaning toward the acceptance of an unconformity, he nevertheless considers the evidence for it still insufficient. Above the Waterlime he recog- nizes the Lower Pentamerus (Coeymans), the Delthyris shaly (New Scotland), the Upper Pentamerus (Becraft), the Cauda- galli (Esopus) and the Corniferous (Onondaga). He did not differentiate the Kingston (Port Ewen) and Oriskany from the Becraft, nor the Schoharie from the Esopus. He also recognizes the complicated southeastern portion of the mountain. Clarke? has published the latest and most complete map of Becraft mountain extant. In this all the formations are de- ' Palaeontology of New York. 1859. 3:39. ? Mus. Comp. Zool. Bul. v.7 (Geol.

The latter could be worked out only by a minute following of the outcrops over the entire field, and by a careful determination of the beds in isolated outcrops. For the latter work, paleontologic data had to be relied on fully as much as lithic characters, since the latter are often nearly identical in distinct horizons. The desirability of a carefully constructed map of Becraft mountain has long been felt, not only on account of the inter- esting stratigraphic as well as tectonic features, which throw - light on the problem of Appalachian stratigraphy and struc- ture, but also on account of the fact that Becraft mountain forms an ideal region for field work with students in geology. Being isolated from the rest of the Helderbergs and of conveni- ently small size, it presents a problem of proper circumscrip- tion to enable something like completion to be attained by the students in the field. Its range of strata, with their well pre- served fossils, most of which are limited to few or only one of the horizons; the various complications by folds and faults of several ages, together with all the more prominent tectonic features accompanying them, and the interesting stream ad- justments and other physiographic features, make this an almost unrivaled field for classwork. Recognizing this fact, Dr John C. Smock, of Hudson, had constructed a detailed topographic map of the region, on the scale of 6 inches to the mile, and with contour intervals of 10 feet. This map has served as the basis of the accompanying geologic map, which was prepared under the auspices of Prof. John M. Clarke, the state paleontologist, and with the partial cooperation of stu- New York, with an annotated list of fossils by J. M. Clarke. Am. Jour.

Nearly all the collections of fossils which have served as the basis of the accompanying faunal lists, were made by the uni- versity parties under the direction of the instructors. The col- lection, however, on which the list of Port Ewen fossils is based was made by myself, that I might be certain of the range of the species. A general map was prepared by the field parties, which afterward served me as a further basis for detailed study. I wish here to express my indebtedness to Prof. John C. Smock, who not only furnished us with the accurate topographic base map, but also rendered other assistance during the progress of the field work.

Davis described this rock,! assigning to it an age “ apparently younger than the Helderberg series, and certainly much older than the drift.” He thought that the limestone fragments “seem to correspond with the several subdivisions of the Lower Helderberg.” He found it at two localities, one in the meadow south of Academy hill and one in the fields a quarter of a mile south of the southern end of the mountain. It is well exposed on a little stream which enters Claverack creek at a point about east of that where fault 16 strikes the eastern bounding road of the mountain. The stream lies on a fault line. It has cut back some distance from Claverack creek and forms a fall over the hard conglomerate, which fall has been utilized as a site for a dam and mill. The conglomerate bed is about 10 feet thick at the fault. It dips northeastward and abuts against what are probably the Normans kill shales, which have a similar dip. The conglomerate increases in thickness away from the fault and forms a prominent hill between the road and the stream.

Its areal relations seem to indicate that it is older than the Normans kill beds of Mt Moreno. Boulders of this rock have been found on Becraft mountain in such a loca- tion that they could not well have been derived fiom any known outcrop. They therefore suggest other outcrops to the north or northeast of Becraft mountain. 2 “HUDSON RIVER” SHALES Ruedemann has shown that the Hudson river shales do not constitute a single stratigraphic unit but rather comprise all the formations from the Beekmantown up to the top of the Lorraine. Nevertheless, these shales constitute a formational unit, with but slight lithic variations, representing continuous deposition, and hence it is advisable to retain the local name, Hudson river group or shales, for this series. At Mt Moreno these shales contain a typical Normans kill fauna in the higher beds. Clarke cites Coenograptus gracilis, Didy- mograptus sagittarius, D. tenuis Hall and other species of graptolites.2, In the lower beds Phyllograptus was found by the Columbia field party. A recent visit in company with Dr Ruedemann resulted in the rediscovery. of the Phyllo- graptus beds in the lower layers at the northwest end of Mt Moreno. In these Dr Reudemann identified Phyllograptus angustifolius Hall, Trigonograptus ensiformis Hall, Climacograptus pungens Rued. (ms), Diplo- graptus dentatus Brogn. and Phyllograptus pos- tremus Rued. (ms). Dr Ruedemann refers these beds to his third Deep kill zone or zone with Diplograptus denta- tus which may represent a Beekmantown horizon. Though no fossils have been obtained from the Hudson river shales of Becraft mountain, it is probable that they are of the same, or perhaps somewhat earlier age. Some of the strata underlying the mountain are somewhat more compact and firmer textured *Ruedemann. Trenton Conglomerate of Rysedorph Hill. N. Y. State Mus. Bul. 49. 1901. p.3.

Beds of hard sili- cious limestone are also found intercalated among the other strata. Similar beds are met with on Mt Moreno. Contact between the “Hudson river series” and the Manlius formation. This contact is everywhere a markedly unconform- able one, the Hudson river strata being much folded and trun- cated by erosion before the deposition of the Manlius limestone. The unconformity takes the place of the strata from the Medina to the Waterlime of Buffalo inclusive, which apparently were never deposited in this spot. The later Champlainic strata, including the Lorraine, Utica and probably part of the Upper Trenton, and perhaps also the Oneida conglomerate, were worn away during the period of deposition of the Siluric strata west of the Hudson. The actual contact between the Champlainic and Siluric strata is shown only in a few places at Becraft. The most important of these is at the outlet of the spring supplying the Hudson aqueduct. This is at the extreme northern point of the mountain. The dip of the Hudson river strata here has not been ascertained, but the cleavage planes stand vertical. The Man- lius rests directly on the Hudson river strata. Another eXpos- ure of the contact is on the old tramroad leading to the quarries, a little north of the Jonesburg road. The strike of the Hudson river beds is here n. 50° e. and the dip is 35° se, the rocks being thin bedded and fissile. The Manlius is seen in the upper part of the cliff, but much disturbed by frost action and slipping, so that the precise character of the centact can not be determined. The dip of the Manlius a little higher up the cliff is from 10° to 12° eastward. A few exposures of the Hudson river beds in the Ancram road south of this, allow the approximate continuation of the contact line. The most continuous exposures of the Hudson river—Manlius contact are found on either side of Fred. G. Lambert’s farm, in the hills facing faults 20 and 21 [see map]. Here 80 feet or more of the Hudson river shales are exposed and the contact can be traced on both sides for several hundred feet, though generaliy the actual line of contact is covered. The Hudson 1038 NEW YORK STATE MUSEUM river beds are much disturbed. Between faults 18 and 17 ex- posures of both rocks allow the tracing of the contact line with fair accuracy, but beyond that the contact can be only approxi- mately determined, since the exposures of ths Hudson river beds are found only at intervals and then at some distance from the Manlius exposures. That there actually is an unconformity between the two sets of strata hardly admits longer of a doubt. Besides the clear indication of the disturbance of the Hudson river strata and the erosion of their upper surfaces, the great time hiatus, extend- ing from the middle Lower Siluric to near the top of the Upper Siluric, is sufficient indication of an unconformity and would a \ ——- CH {eal POWs W\ Fig. 3 Contact of Manlius limestone (6), with Hudson river shales (a) and Coeymans limestone (c), northern margin of Becraft mountain be, even if this were not brought out in the structure. Such an absence of formations, when not due to faulting, as is clearly not the case here, can be accounted for only by nondeposition or by subsequent erosion. And the former in this region at least is, like the latter, indicative of land conditions. REPORT OF THE STATE PALEONTOLOGIST 1902 1039 3 MANLIUS LIMESTONE The best place for the examination of the Manlius limestone of Becraft mountain is along the northern margin of the moun- tain, in the city quarry, and at the Hudson aqueduct. At the latter place, just west of the old tavern in Greenport, the entire thickness is shown. At this point a powerful spring issues — from the mountains, the water of which supplies the pumps in the city of Hudson. In the bed of the stream formed by this spring the “ Hudson river” slates are exposed. They are much contorted and cleaved, the cleavage planes standing vertical. The direction of bedding could not be determined. Resting on this are the lower Manlius beds, with a dip of 35° to 40° south- ward, the strike being n. 70° e. A little higher up the dip flat- tens to 20°, which is normal for the rock at this point. The measurements at this point are as follows [see fig. 3]: From basal contact to base of vertical cliff, the interval oe being a slope with the rock more or less concealed..... 18 Hight of cliff portion 34 feet, which, with dip of 20° gives for the thickness of the beds...................-....- 32 Thickness of beds forming upper slope from edge of cliff to contact with overlying Coeymans................. 5) Total thickness Of Manltis 0 55 No fossils were found at this place. At the city quarry in the cemetery off the Newman road (middle longitudinal mountain road) a total of 28 feet of the Upper Manlius is exposed, only 18 feet of which however are shown in the northeastern end of the quarry wall. It is over- lain by 32 feet of Coeymans limestone. (Fig. 4) The limestone in this as in the other exposures is a compact finely stratified lime-mud rock, a type of deposit for which the “name calcilutite has recently been proposed! Leperditia alta is fairly abundant in certain layers in the upper part of the series, and is the only fossil found in these beds outside of the Stromatopora layers noted below. The dip of the strata is 12° s.e., the strike is n. 40° e. a ee — NNN Oa OO _ ——_ 1Science. n.ser. Feb. 20, 1903. p. 297. 1040 NEW YORK STATE MUSEUM Just below the lowest bed of the Coeymans limestone occurs the upper Stromatopora bed, forming the topmost layer of the Manlius. It averages 314 feet in thickness, varying between 3 and 4 feet, and is for the most part made up of masses of stromatoporoids piled one above the other. In weathered sec- tions these masses are well shown, being less readily seen in the fresh section on account of the massiveness of the rock. Sometimes at the edge of the cliff they are weathered out, so that they look like piles of boul- ders. The largest head measured is about 114 feet in diameter. The bed immediately above this layer contains Favosites, crinoid joints and Gypidula galeata, and in texture is finely crystalline. This crystal- line matrix frequently extends oe a Petes Sate ame ee down between. the Stromatop- Stromatopora beds; 3, 5, 7, Manlius. ora heads, but more frequently the fine mud-rock fills the inter- stices between the masses of hydrocoralline. The lower line of the Stromatopora bed is very irregular, and sometimes a Stroma- — topora is embedded in the stratified Manlius below. The “Stromatopora” fragments probably all belong to the genus Syringostroma of Nicholson, but their exact determina- tion is a matter of great difficulty on account of their unsatis- factory preservation and it has not been attempted. Besides the stromatoporoids, the following fossils character- ize this bed. Spirifer vanuxemi Hall This species is represented by a few individuals in the upper Stromatopora bed. They agree substantially with the figure of Orthis plicata given by Vanuxem, which is the char. acteristic Manlius limestone species of eastern New York. The median sinus of the pedicle valve of our specimens is shallow, REPORT OF THE STATE PALEONTOLOGIST 1902 1041 rounded at the bottom, and somewhat narrower than is usual in this species. It is flanked by about four rounded plications on each side, which widen gradually toward the front of the shell. The brachial valve has four plications on each side of the central ) fold, the fourth being very short and BS much fainter than the others. The Fig. 5 dbecitex vanuxemi, Median depression along the top of Raw. aa the fold is marked in some cases, in others it does not occur at all. The plications, as well as the sinus and fold, extend to the apex. So far as I have been able to examine specimens of S. vanuxemi typical of the Manlius of eastern New York, the de- pression in the median fold of the brachial valve, where it occurs, is a feature of maturity rather than characteristic of the entire shell. In a few cases the depression in the fold can be traced nearly or perhaps quite to the apex of the valve. When the depression is well marked, the plications appear sharper and comparatively narrower. They also extend farther up the beak. On the other hand, it appears to be the case that, when the depression in the fold is faint or absent, the plications are less defined and near the apex become obsolete. Neverthe- less, there are individuals in which the depression in the fold and the broadly rounded plication occur together. Finally, individuals occur (as figured by Hall) in which the apical por- tion is free from plications, these beginning part way down. In this case they are, so far as observed, broad and rounded. The young individuals of the species are in all cases marked by less pronounced and fewer plications. In certain forms, which may be considered the more primitive representatives of the species, the young are practically free from plications, or if these occur, they are broadly rounded and low, one or two only occurring on each side of the fold or sinus. From these considerations we arrive at the conclusion that the ancestral type from which 8S. vanuxemi was derived, was a pauciplicate if not nonplicate form. Furthermore, that those individuals among the species which have few and low plications, with a 1042 NEW YORK STATE MUSEUM smooth apical portion, are the least accelerated, while the extreme of acceleration would show strong plications on the beak, with a median depression on the fold, which in extreme cases commences near the apex. In rare cases is there a faint median fold in the sinus of the pedicle valve. Similar modifica- tion through greater or less acceleration is found in the mid- Siluric relative of this species, S. crispus, which seems to be a parallel development. Spirifer corallinensis Grabau Geol. Soc. Am. Bul. 1899. 11:352. This name was proposed, as a varietal one, for the character- istic Spirifer of the Coralline (Cobleskill) limestone of Scho- harie. This was referred by Hall to S. er is pus and figured on plate 74, Paleontology of New York, v.2. The type specimen! — is transverse, wider than high, with rounded ends. The sinus of the pedicle valve is very shallow, rounded and narrow. Beak of pedicle valve incurved and area comparatively low. In this respect the species is like S. ecrispus. In a weathered-out specimen Fig. 6 Spirifer corallinen* surface markings similar to 8S. cris pus are shown. §!* Pedicle valve This species approaches closest to the simpler types of the New York 8S. crispus, that with fewest plications. A speci- men from Lockport [Am. Mus. col.1421] shows the relatively high and subrhomboidal outline, with a shallower sinus, which is rounded and widens less rapidly than in the normal form of S. crispus. There is one moderately strong and one very faint rounded plication on each side of the sinus, and two similar though fainter plications on each side of the fold. Dimensions of the type specimen, length 11.5 mm, hight of pedicle valve 10 mm, of brachial valve 8 mm, transverse diameter 7 mm. Another characteristic specimen from the same bed (Coralline of Schoharie) is figured by Hall [fig. 8d]. It is proportionally narrower than specimen fig. 9d—f, and has a somewhat more pronounced almost subangular sinus. The width of this specimen is 11 mm, hight of pedicle valve 10.5 mm. 1 Op. cit. pl. 74, fig. 9 d-f. Am.

The plications are almost invisible and the sinus narrow, very shallow and rounded. This species is well represented in the upper Stromatopora bed of the Manlius limestone in the city quarry at Becraft. Its main distinguishing features are its subrhomboidal outline, shallow, narrow and rounded sinus, and obsolete or faint, broadly rounded plications. In the latter two features it differs materially from S.eriensis Grabau.

Bul. 1899. 11:366, pl. 21, fig. 2a-b A variety of this species is more common in the upper Stroma- topora bed at Becraft than 8S. corallinensis. It is char- Fig. 7 Spirifer eriensis var. acterized by a deep angular sinus with straight sides which diverge uniformly and regularly forward. It has narrow and more widely separated plications than S. corallinensis, and they become faint or obsolete in the upper part. A moder- ately strong plication occurs on each side of the sinus and 1044 NEW YORK STATE MUSEUM another weaker one outside of this on each side. There are faint indications of a third one beyond that. The shell is character- ized by fine regular concentric lines which mark the edges of narrow imbricating lamellae. Fine radiating lines, interrupted by the concentric lines, are visible on well preserved specimens, giving a surface sculpture essentially like that of S. coral- linensis, S. vanuxemi and S. crispus. The fold of the brachial valve occasionally shows a faint iongitudinal depression. Measurement of specimens from Becraft mountain.

The number is also less, so that, whereas in the Williamsville specimens there is a total of eight plications, only six can readily be made out in the Becraft speci- mens. The concentric surface striae are the same in both. The brachial valve of the Becraft specimens is somewhat more con- vex, with the plications a little more pronounced, particularly the ones next to the median fold. | A single specimen from the Cobleskill of Schoharie (Am.

Genetic relationship of the Spirifers of the S. crispus type The similarity between S. corallinensis of the New York Manlius and Cobleskill and S. modestus of the Manlius! of Cumberland Md. has already been referred to. It Real ee | SEE = oe Se ee he ae ee ‘es 12 _—_ : REPORT OF THE STATE PALEONTOLOGIST 1902 1045 seems probable that S. corallinensis was derived from 2 smooth form similar to S. modestus,! though the chances of its having been derived directly from that form are slight. A type which answers more readily the requirements of a radicle for this species as well as the others of this group, is Spirifer petilus Hall of the Niagaran beds of Waldron Ind. This species in the adult stage has all the characters of the young of S. erispus var. simplex and 8S. crispus, as pointed out by Beecher and Clarke2 S. corallinensis and S. eriensis are connected by intermediate forms. In some specimens from Becraft mountain, which show the adult char- acters of S. eriensis, the younger portion of the shell has all the characters of S. corallinensis with narrow shal- low sinus and obsolete plications. As the shell is exfoliated, it is not possible to say whether or not the plications are wholly absent in the young, as appears to be the case. The derivation of S. eriensis from S. corallinensis is then very clear, this being shown by morphogenesis as well as chronogenesis. In like manner it can be shown that S. vanuxemi was derived from S. corallinensis by an accelerated development of the plications, while the fold and sinus were retarded. The most accelerated individuals of S. vanuxemi have, as already pointed out, a depression along the middle line of the fold which in extreme cases reaches the beak. These three species, 8. corallinensis, S. erien- sis and S. vanuxemi, though occurring in the late Siluric beds, are all retarded in development with reference to the plications, when compared with 8S. crispus, which was derived from the same stock in the Midsiluric. In fact, these late Siluric species, if not known to occur above S. crispus, would be placed chronologically below or with that species Regarded however as retarded types, placed in an unfavorable environment, their more primitive characters are understood. *Schuchert has recently pointed out [U.S. Nat. Mus. Proc. 1903. 26:413] that a number of the species referred to the Cumberland Helderbergian really belong to the Manlius horizon of that locality. Among these is S. modestus. 7N. Y. State Mus. Mem. 1. 1889. p.75. 1046 NEW YORK STATE MUSEUM S. petilus of the Waldron Siluric beds is succeeded genetically, though not chronologically, by 8S. crispus sim- plex, and this in turn by the normal 8S. crispus. There is also a strongly accelerated type in the Waldron beds which is characterized by a depression in the fold and rarely an eleva- tion in the sinus, and by angular plications. The normal New York type of S. crispus has strongly rounded but narrow plications, with a moderately deep, rounded sinus, which broadens strongly toward the front. This species was undoubtedly derived from the Waldron 8S. crispus by migration. Whether the pauciplicate rhombic type above mentioned is due to a direct immigration or to retardation of the normal S. crispus of New York can not be readily determined. The same may be said of S. bisulcatus Van- uxem, which is still more primitive, or more retarded. The results of our present studies in the phylogeny of these species may be summed up in the annexed diagram. REPORT OF THE STATE PALEONTOLOGIST 1902 1047 ee eee eS aD WESTERN NEw YORK WALDRON IND.

To these upper beds Davis gave the name of Upper Shaly limestone which was later on changed to Kingston beds by Clarke & Schuchert.2. This term was, however, preoccupied by various authors for formations of Precambric, of Siluric and of Pleistocenic age, and Clarke has since proposed the name Port Ewen beds, from the town opposite Rondout, near which these beds are best exposed. The thickness of these beds near Port Ewen station on the West Shore Railroad is recorded as 222 feet. Van Ingen and Ruedemann divided them into 18 subdivisions and made exten- sive collections from these, which have been published by Clarke.* On the authority of these collections, Clarke states that “the fossils of all its layers are those of the true New Scotland lime- stone faunas, the contents of the higher layers varying little from those of the lower.”” As no such formation seemed to occur at Becraft mountain, where the normal succession of strata is undisturbed and clearly exposed, I visited Rondout hill in com- pany with Dr John C. Smock, in order to study the formation at the type locality. Accompanied by Mr P. E. Clark, the mining engineer of the cement works, I made a careful examination of critical points on the hill, expecting to find the lower Shaly beds * Am. Jour. Sci. 1883. 26:389. *Science. Dec. 15, 1899. *Qriskany Fauna of Becraft mountain, p. 73. 1064 NEW YORK STATE MUSEUM repeated by overthrust faulting. Above the Becraft limestone and below the beds pointed ont by Mr Clark as “ Upper Shaly,” and so mapped by Davis and Darton, the Coeymans limestone was found in full force with characteristic Gypidula galeata and Atrypa reticularis, as well as the chert beds characterizing it as Becraft. Above the “Upper Shaly,” after careful search in the woods, the typical Becraft limestone was found, which in turn was overlain by a darker, fine grained limestone identical in character with the beds lying between the Becraft and Oriskany at Becraft mountain. Above this was found the Oriskany. On extending our observa- tions, Mr Clark pointed out a spot where the Becraft, inclined about 50°, was quarried below, and the Rondout waterlime, inclined at 42°, was quarried above it. On examining the contact between the limestones below the point where the Coeymans was found overlying the Becraft, in the roof of an old quarry in the latter rock, it was found that the line of supposed overthrust was clearly marked by extensive slicken- siding of the adjoining strata.t A subsequent visit to this hill in company with Dr Ruedemann showed the essential correctness of the interpretation of the structure, but it was found that the thickness of the beds lying between the Becraft and the Oriskany was greater than at first supposed, Dr Ruedemann measuring 110 feet. A yisit to the section in the West Shore Railroad showed a great thickness of the Upper Shaly beds between the Becraft and the Oriskany. The section made by the railroad however is, as pointed out by Mr Clark, a diagonal one and numerous small faults occur in it so that the actual thickness would be less than 222 feet, as recorded by Clark. Since the interval between the Be- craft and the Oriskany can be readily measured on Rondout hill, though the beds occupying that interval are poorly exposed, it ‘No ‘“‘ Upper Shaly ”’ beds are recorded by Davis in his sections and descrip- tions of the ‘‘ Little mountain region” east of the Catskills. His map covers an area of about 10 miles in length and throughout this the Oriskany, where present, rests directly on the 120 feet of limestone which he referred to the Upper Pentamerus (Becraft). The upper part of these undoubtedly represents the Port Ewen of Becraft. REPORT OF THE STATE PALEONTOLOGIST 1902 1068 seems probable that the Port Ewen section, which is not more than a mile and a half south of the former, contains not much more of these beds. Darton estimates the thickness as 125 feet in the central and southern portion of Ulster county, and states that it decreases northward to 30 or 35 feet in the Saugerties region, near the Greene county line The Upper Shaly beds of the Port Ewen section have a thickness of from 100 to 200 feet, but except along the roadside, they are poorly exposed on Kings- ton hill. They, together with the Becraft and the repeated Lower Shaly, were mapped by Davis and Darton as Upper Shaly, while the characteristic fossils cited by these observers were obtained beyond doubt from the repeated Lower Shaly beds, for Spirifer macropleura and Orthothetes radiatus cited by Davis and Darton as characteristic of the Upper Shaly do not _ appear in Clarke’s list of these beds as exposed in the Port Ewen section. At Becraft mountain these beds are well shown. They are dark crystalline limestones recalling the Coeymans limestone. They crop out in a series of steps with a total thickness of not over 25 feet. They are particularly characterized by the Monticuliporoid Monotrypella tabulata, which may be easily recognized by the transversely wrinkled aspect of the corallites. This species is however not restricted to this hori- zon, being also known in the Coeymans limestone. The best exposures of the Port Ewen beds are along the quarry road from the old Jones quarries to the transverse mountain road. Here the thickness can be best determined, and the char- acteristic fossils obtained. The bluffs here rise up to 15 or 20 feet in hight, and above them there is a continuous slope east- ward, conformable to the dip of the strata, to a low swampy meadow, where fragments of Oriskany limestone indicate that the contact is near. Allowing for a slight addition above, and a similar addition below to the contact with the Becraft, I do not think that the total thickness of the Port Ewen at Becraft moun- tain will exceed 25 feet. 'N. Y. State Geol. 13th An. Rep’t. 1894. p. 304. 1066 NEW YORK STATE MUSEUM In lithic character the Port wen beds of Becraft resemble the Coeymans, and, like these beds, they contain more or less chert. The similarity is emphasized by the occurrence of Monotr y- petla tabulata in both. The paleontology of this limestone still needs a careful study. The following annotated list represents the species found in a brief examination of this rock during the progress of mapping the contacts.

The Manlius is here much jointed, with vertical joints which on weathering give the aspect of vertical bedding. Shortly before reaching the bend in the wood road, where it leads off to the Becraft quarries, a sink hole of moderate depth is met with. There are several of these on Becraft, which point to a more or less cavernous condition of the low lying limestones. Faults 4 and 5 appear to bound the keystone of a small anticlinal fold, which has collapsed at the center. The strata on either side of the central fault block are dipping away from it. Fault no. 5 also permitted a lateral displacement of the blocks. South of fault no. 5 the surface rock is the Coey- mans, which, together with the dip of the strata, would give about twice the known thickness of the Coeymans. It seems therefore highly probable that another fault (no. 6) runs through the center longitudinally. The throw is of course not so great in this second block, since no Manlius has been brought to light. Fault no. 6 must be regarded as the continuation of fault no. 3. Both of these faults are earlier in date than fault no. 5. Fault no. 7 is another gravity fault with the downthrow on the south- eastern side, and the strata of this portion steeply turned up on the fault plane. West of this the strata are strongly folded, as shown in section 6. Fault no. 8 is more of the nature of a breached anticlinal fold, though a slight displacement seems to have occurred at the axis of the fold, where a small stream runs from the mountain side. All of these displacements and extra folds die out toward the southwest, as shown in section 12a, where only a single fold (anticlinal 1) can be made out. Unlike the preceding faults, which mostly had a uniform direction (about n. 40 e.) or else were parallel to the strike. fault no. 9 has a direction a little south of east. It cuts off the _ end of syncline no. 2, causing a partial repetition of some of its strata, i. e. Becraft and New Scotland. The downthrow in this case is on the north side of the fault. 1074 _ NEW YORK STATE MUSEUM South of this fault, the structure becomes more complicated. The eastern sharper and more closely crowded folds now appear, and with them a number of thrust as well as gravity faults. The structure of this area, as far as section 20, is shown on a larger scale on the section map, and will now be described in detail. Just south of the point where Claverack creek strikes the eastern road, i. e. at fault no. 9, we meet with one of the numer- ous, more or less overgrown wood roads which lead up the mountain. Following this road, which leads off westward from the main road, we find, on turning at a bend, that we are follow- ing a depression along the strike of the strata. This depression marks the location of fault no. 10, a strike fault. To the west of this fault the strata dip 20° to 25° westward, while on the other side they dip as much or more to the east. The strike of the Manlius and the overlying Coeymans, east of the wood road, is at first nearly east and west, the dip being as high as 30° or 35° to the south. This is caused by fault no. 11, a short diagonal fault between 10 and 12. Between this shorter fault and the main strike fault (no. 10) a triangular surfaced block has been tilted to the degree indicated by the dip. As this block stands now, only the Coeymans and Manlius compose it. East of fault 11 the strata dip steeply to the southeast, the angle ranging from 50° to 75°, while the strike is n. 30° e. Nearly the entire thickness of the Coeymans is exposed three times in the region of these faults, as shown by section no. 7. The Manlius forms the eastern portion of the section, dipping, as far as exposed, about 60° to the southeast, thus showing a complete overturn of the strata, the Manlius resting on the Coeymans. South of the triangular fault block the structure is somewhat simpler, being affected only by two longitudinal strike faults. The first (no. 10) brings the steeply eastward dipping New Scotland (70°, s. 60° e.) against the gently inclined westward dipping Coeymans (20°, n. 60° w.), as shown in sections 8, 9 and 10. To the west of the fault the beds from the Coeymans up are shown, while on the east of this fault, the New Scotland, Coeymans and Manlius are found in the reverse order, owing ‘ ae als fa Le 4 REPORT OF THE STATE PALEONTOLOGIST 1902 1075 to the overturning of the beds. A second longitudinal or strike fault (no. 12) begins in the Manlius on the northeast and a little later passes into the Coeymans [section 10] ending finally in a small diagonal fault. Thus once more eastward dipping beds are brought in contact with the steeply overturned strata, par- tially repeating the Manlius in the upper, and the Coeymans in the lower section (nos. 9 and 10). A little farther southward, another triangular fault block occurs, bounded by faults 11, 18 and 14. The probable struc- ture of this block is shown in section 10. On the east the over- turned Manlius, Coeymans, New Scotland and Becraft are visi- ble, all dipping very steeply to the southeast, some beds being almost or quite vertical. A low ridge of Becraft with the strata standing vertically, is succeeded westward by a flat valley [see section 11] in which no strata are exposed. This valley is bounded on the west by fault 10, beyond which is another ridge, on the summit of which the Becraft is again seen dipping 40° northwestward. No exposures are shown at the base of the ridge at this point, but it is almost certain that the New Scot- land lies at its base and that it is merely a southward con- tinuation of the same structural ridge found just northward, where the New Scotland is shown. The westward dipping strata are bounded on the east by fault 10, which has here turned more to the west. What strata occur between the fault and the low ridge of Becraft have not been ascertained, as no satisfactory exposures were noticed. Some rock masses which appeared to be in place, were finely crystalline, shattered and veined limestones, which may represent either the Coeymans or Port Ewen. No fossils were obtained, but from the character of the strata a little farther south [section 14], it appears most natural that the valley is occupied by a closed synclinal fold of Port Ewen, with possibly some Oriskany in the axis of the fold (which would account for the valley). The Becraft probably comes up again on the other side of the syncline, next to the fault. Fault 14 is followed by an old wood ‘road, which leads down to the main road east of the mountain. South of this fault the Manlius forms-the greater part of the surface. It 1076 NEW YORK STATE MUSEUM forms a synclinal trough, the axis of which dips 10° southward. The appearance of this portion of the surface is therefore some- thing like half of a shallow basin. On the western side of the trough the rocks are sharply overturned, so that they dip 80° to the eastward, but with their uppermost side down. This overturn fold bounds a flat bottomed tract or longitudinal val- ley. On tracing the fold southwestward along the strike, it is found that less and less of the upper Manlius strata are uncoy- ered in the axis of the fold; and that, finally, they are covered en- tirely by the Coeymans limestone. This again shows the south- ward pitch of the fold. As shown by the eastern ends of sections 14 and 15, the strata there are involved in another simple anti- clinal fold (no. 4), which, from the southward pitch, is formed on the present surface by progressively higher and higher strata in that direction. The western boundary of the aforementioned longitudinal, flat bottomed depression [section 14] is formed by a double ridge of Becraft, the eastern portion of which dips 60° eastward, while in the western ridge the dips are 25° to 30° to the west. A little farther south [in section 15] only the west- ward dipping ridges of Becraft, capped by Port Ewen and under- lain by New Scotland, occur. This shows that a fault line passes between the two sections. This fault is well marked to the southeastward, where the Manlius is thrust over the Coeymans. This overthrust fault is finely shown in the cliff facing the road- way along the eastern border of the mountain. Here the rela- tions shown in the following diagram are clearly exhibited. This overthrust fault appears to be earlier than, or at least contemporaneous with, the longitudinal strike faults (10 and 12), for the latter are not seen south of the overthrust fault. This fault may be traced northwestward as far as the little brook which drains the great meadow. Here it appears to pass into a strike fault and is not traceable any farther. As we go south- ward, the pitching axis of the fold reveals another fold as shown by the sections [15-20]. These folds are of the typical Appala- chian type, with a steep, overturned limb on the west and a gentler, normal limb on the east. Eastward this eastern limb again passes under and rises as the steep or overturned western REPORT OF THE STATE PALEONTOLOGIST 1902 1077 limb of a second anticline. That this was another similar fold to the one discussed appears on comparing sections 14-20. It is highly probable that the western end of section 15, from the axis of the overturn fold now shown in the Coeymans near the iniddle of the section [A], was of the type of those of section 20. a ay EILEEN SS=== NEESER re DOOKIE ISS bee Fig. 13 Overthrust fault with infolded Manlius (a) and Coeymans (6) If the latter section were added to the eastern half of section 15, so that the extreme eastern end of 20 [A] coincided with the axis of the overturn anticline [A, section 15] we would restore what appears to have been the normal type of folding of this region. Beginning on the east, there was a simple anticline with the limbs nearly equal. This was followed by a broad syncline, with a gentle westward dipping limb on the east and a more abruptly eastward dipping western limb. The latter formed the eastern limb of the overturned anticline, which had almost become an isocline. The strata came up again in a broad syncline with overturned eastern and low western limb, after which they were again involved in an overturn anticline of the Same type as the preceding. A similar syncline to the last fol- lowed, and was in turn succeeded by a third overturned anti- cline in the Onondaga, as shown in section 21. The syncline following this is of the same type as the two preceding; its western limb, with an angle of 12° or 15° eastward dip, forms the western side of Becraft mountain. We may safely assume that three close overturned anticlines existed, besides the appar- ently uniform anticline on the extreme east. The overthrust fault no. 15, the direction of thrust of which was from the south- west, produced a northward as well as eastward displacement 1078 NEW YORK STATE MUSEUM of the strata from the southwest, thus bringing the axis of anticline 5 southwest of the overthrust [A, section 20] some 400 feet farther northeastward than its continuation north of this fault [A, section 15]. By this overthrust the western limb of syncline 3 [B, section 14, which corresponds to B, section 20] steepened from 30° to 60°, making this syncline nearly a closed fold. Going southwestward from section 20, the axes of the folds continue to pitch downward, so that higher and higher strata come to form the surface. This is well shown by a comparison of sections 20 and 21 and by reference to the map. We pass from the New Scotland beds, which in section 20 form the pres- ent top of syncline 3 and anticline 2, to the Becraft and later on to the Port Ewen, only the steep eastern limb of syncline 3 remaining aS a narrow band for each of the lower formations. The descent continues to fault 17, where an oblique shifting of all the strata occurs. Thus, as shown in section 22, the over- turned western limb of anticline 3 (the only portion of that anticline remaining) is repeated, the repeated portion however being more strongly overturned. From this fault the axes of the folds rise southward, lower and lower members being pro- gressively uncovered in the eroded anticlines. This is seen on comparing sections 22 and 23, the position of the latter with reference to the former being indicated by the dotted line in the lower portion of section 22. On comparing anticline 23 of sec- tions 22 to 25, this same southwestward rise or northeastward pitch of the folds is shown. It is thus apparent that on oppo- site sides of fault 17 the folds pitch toward each other, and it is noteworthy that at this, the lowest point of the strata, the stream which has its valley wholly on the Oriskany outcrops, breaks across the strata to join Claverack creek. It is at this point that the axis of anticline 2 is so low that the hard lime- stones are carried below the present level of the stream on the Oriskany outcrop, thus making this the natural point of exit. A comparison of sections shows, that the folds steepen toward the northeast and also become more closely crowded. Hence the lines marking the anticlinal and synclinal axes are closest i REPORT OF THE STATE PALEONTOLOGIST 1902 1079 together in this portion of the map. The pitch of the folds is well shown by the outcrop of the Port Ewen and Oriskany of anticline 1 and syncline 1 and 2. The adjustment of the stream to the Oriskany outcrop, or more specially to the con- tact between the Oriskany and Esopus, is well shown [compare section 24]. Fault 18 cuts off these folds abruptly and, to- gether with fault 19, which is its continuation, bounds this area. West of these faults, we have a strongly eastward pitching, sim- ple syncline, with gentle northern and vertical southern limb. This is a section of syncline no. 1, which, from representing the upthrow side of the fault is alone found, all the more southern folds having been worn away [see section 26]. To the north of this syncline is a steeply eastward pitching anticline, which is apparently unrepresented in the other por- tions of the mountain. This fold is broken in the center, and a long narrow block, bounded by faults 20 and 21, has dropped down. Where these two faults converge, is a large, flat bot- tomed meadow, inclosed on all sides except the southwest, by steep banks which rise in places to a hight of a hundred feet or more. The meadow is drained through the open end by a west- ward flowing stream. The sides of this depression are so steep and fresh and the bottom so flat, as to suggest some recent movement along the bounding fault planes. The inclosure on the three sides is so abrupt, as to make any other explanation difficult. Moreover, the bottom of the depression is underlain by the New Scotland beds, the same which form the sides of the hollow, and there is no assignable reason why one part should be so maturely eroded while the adjoining portion is still so fresh. It is not improb- able that this impression represents a sink hole of unusual dimensions for this portion of the country. The approximate dimensions of the depression at the bottom are: length 650 feet; greatest width 300 feet [see section 26]. Beyond fault 21 to the northern extremity of the mountain, the structure is very simple and uniform, as shown by section 1. A NEW EURYPTERID FAUNA FROM THE BASE OF THE SALINA OF WESTERN NEW YORK! BY CLIFTON J. SARLE With 21 plates ‘INTRODUCTION . In western New York the outcrops of the Salina strata occur in a belt of country averaging 10 miles in breadth, parallel to the southern shore of Lake Ontario, and its northern limit dis- tant thence about 15 miles. On the Rochester meridian the for- mation is 600 or 700 feet thick, and, in the lower portion, com- prises variously colored shales or marlites, interspersed with some thin layers of dolomite, while in the upper portion are salt and gypsum deposits with some beds of waterlime and limestone. The exposures of the formation in this part of the State are few, owing to the very destructible nature of the rock and to a heavy covering of drift. No sedimentary strata in the State have been considered more barren of fossils. Resting on the Lockport dolomite, which is everywhere replete with fossils, and underlying the Bertie waterlime, which at many: locali- ties carries a rich assemblage of eurypterid remains in the thin layers at the top, it has formed a conspicuous break in the paleontologic record. It is therefore a matter of considerable interest to announce a rich eurypterid fauna, discovered by the writer in 1898, in the basal layers of the Salina formation, in Monroe county. This fauna, though separated from that above by nearly the whole thickness of the Salina, is its counterpart in many respects but perhaps more primitive in its characteristics. The discovery thus affords additional ground in support of the com- prehension within the Salina of all beds included between these faunas. Formerly this association was based entirely on stratigraphic succession and a supposed similarity of physical conditions, from which it was assumed that a similarity of life must be found. It is safe to state that this is the earliest fauna yet known to which the name “eurypterid fauna” can be properly ap- Since this paper was put in type it has been accepted by the faculty of the University of Rochester as a thesis for the degree of master of science. REPORT OF THE STATE PALEONTOLOGIST 1902 1081 plied. The remains from earlier formations are extremely rare and, almost without exception, very fragmentary. Euryp- terus boylei Whiteaves (1)! was described frém a single nearly complete body found in the Guelph dolomites underlying the Salina in Ontario; Eurypterus prominens Hall (2), from a cephalothorax referred on doubtful grounds to the Clinton of Cayuga county, N. Y.; fragments of Pterygotus were described by Barrande (8) from the Siluric of Bohemia; the genus Echinognathus Walcott (4) was described from a single limb found in the Utica shale (Lower Siluric) of New York; Eurypterina Walcott (5), from fragmentary remains found in the Belt terrane (Precambric) of Montana; and recently, the genus Strabops Beecher (6), from an essentially entire body found in the Cambric of Missouri. Other forms of life occur with the eurypterids in this fauna, but they are comparatively inconspicuous and have no effect on the general facies. The entire fauna comprises: Graptolitida 1 Ostracoda 1 Annelida (denticles) 3 Phyllocarida 2 Brachiopoda 1 Synxiphosura 1 Pelecypoda 1 Eurypterida 6 Cephalopoda 2 — Total 18 Three species from the original collection made by the writer, have already been described by Dr John M. Clarke (7), viz, two phyllocarids representing the genera Ceratiocaris (C. prae- cedens) and Emmelezoe (EK. decora), and a merostome belonging to the synxiphosuran genus Pseudoniscus (P. roosevelti). Five new species of eurypterids and a variety of one of these are here recognized, representing four genera, one of these being new to science. The specimens re- ferred to four of the species are so fragmentary that at present they do not warrant complete determination, it being preferable to wait till more perfect examples have been obtained. These fragments, however, have been figured and will be referred to briefly. See references on p. 1109. ~ 1082 NEW YORK STATE MUSEUM The collection was obtained from excavations made in deepen- ing the Erie canal during the winter of 1897-98. The precise locality begins at a point a few rods east of the Brighton- Pittsford line in the latter, township and extends southeast for a distance of about 300 yards. Though the exposure did not at any one point exceed 9 feet in hight, yet, owing to the dip of the strata toward the east, higher levels were brought down to view, so that the entire vertical section was about 16 feet. The rock is a soft shaly marlite, in layers of different colors, often mottled, and interspersed with a few thin layers of very hard, fine grained dolomite. The eurypterids are found in a rather fissile, very dark olive- green to black shale, which, like the adjacent argillaceous strata, rapidly disintegrates on exposure.

REPORT OF THE STATE PALEONTOLOGIST 1902 1083 The proximity of this cut to wells penetrating to the Lockport dolomite, and to exposures on the west branch of Allen creek within half a mile to the north, show that the section is located on the northern edge of the Salina formation, hence approxi- mately at its base. The accompanying table, representing the beds lying between the black shale and the Lockport dolomite, as well as those for some distance above, was made from an examination of well sections a little to the westward of the fossil locality, and from a series of outcrops along the creek. The level of the black shale is thus ascertained to be about 20 feet from the base.

NEW YORK STATE MUSEUM The portion of this section which corresponds to that in the canal cut, is seen to show some differences. However, the rapid changes in character of the superposed beds may be taken as a good indication of the limited lateral extent of most of them. The red shale appearing in the upper part of this sec- tion is the same as that exposed in the upper part of the canal cut. At Pittsford, 2 miles southeast of this cut, the canal is excavated through red shale mottled with green. At Carters- ville, 2 miles farther southeast, this same rock occurs in the canal bed and 40 feet lower in the waste weir. At Fairport, 4 miles northeast of this, it is again exposed in the canal, and by well-borings is shown to have a considerable thickness at that place. It thus appears that this red shale corresponds to the lowest division of the Salina recognized in western New York by Hall, and immediately overlies the stratum containing the fauna herein described. | A few important facts relative to the physical changes attend- ing the introduction of the Salina fauna into the area are well illustrated by these sections. The exposures on the west branch of Allen creek, from which the lower part of this sec- tion was taken, show in the upper portion a progressive change of conditions: first, from those of the Niagara sea, in which stromatoporid reefs were widespread and an incipient Guelph fauna flourished, to those under which thin layered, impure, ripple-marked dolomite was deposited and fucoids appear to have been the only forms that abounded; then, to conditions for the formation of a tough, porous, very bituminous lime- stone, succeeded by a phase during which a stratum of thin- layered, bituminous accretionary limestone, forming flat, imbri- cating, shell-like domes,! was deposited; and, finally, to condi- ‘This rock is the same as that south of Lockport, Niagara co. noted by Hall, Geol. N. Y. 4th Dist. p.92, and also exposed in the southern part of the city of Niagara Falls. It is probably identical with that described by Vanuxem in the Geol. N. Y. 3d Dist. p.91, as a limestone, small in quantity and in hem- ispheric concretions, whose parts are more or less concentric to each other like the coats of an onion, and regarded by him as an attenuation of the Lockport dolomite. ae REPORT OF THE STATE PALEONTOLOGIST 1902 1085 tions during which 2 feet of light yellowish impure limestone, showing on the weathered surface casts of a very finely branch- ing organism, probably a plant, were formed. On this rests a ereenish shaly marlite, the basal stratum of the Salina. The next layer consists of a bench of waterlime marked by shrink- age cracks, indicating a temporary exposure to the air during the time of formation. It is thus seen that preparatory, as it were, to the coming of the Salina fauna, there was a marked change in physical conditions. The shallowing of the sea, with a probable increase of salinity and turbidity of the waters, probably had more than anything else to do with the displacing of the Niagara fauna. While these changes were going on, the first of the Salina fauna, a Pterinea, a little more rhomboid and convex than P. emacerata of the Rochester shale, appeared. Later, in the waterlime bench, besides the Pterinea, a Lingula, a Leperditia (L. scalaris), and also an Orthoceras, occur. With the exception of the last, which has not been noted else- where in this section, these fossils make their next appearance in the black shale, where they are accompanied by the eurypterids. | The eurypterids are by no means uniformly distributed throughout this shale. The species representing the new genus to be described, occurs most abundantly in the lower half, where it is so prolific that certain planes are literally packed with its remains, making this probably the richest eurypterid stratum known. The genus Eurypterus, represented by a single large species, occurs most frequently in the upper half of this black shale, just above the 2 inch limestone parting. The Ptery- gotus head [pl. 24, fig. 7] was also found in the upper portion. The dolomite layers associated with this black shale are marked by an almost complete absence of eurypterids, the Leperditia and Pterinea, with the exception of an occasional specimen of a small pentalabiate Gomphoceras of character- istic Siluric type, being the only forms found in them. From the fact that the occupation of the area by the merostome fauna followed one of these dolomite-forming intervals, was twice % 1086 NEW YORK STATE MUSEUM interrupted by the accumulation of marl, and finally was closed by another lime-forming interval, it is evident that the condi- tions at these times were not favorable to the eurypterids. These dolomitic limestones probably represent more open water, or the temporary removal of some barlike barrier, and, probably, a diminution in the salinity of the water. Though the fine char- acter of the silt forming the black shale and the evidence of interrupted sedimentation noted above, indicate slow accumula- tion, the occupation by the eurypterids was apparently of comparatively short duration, merely an incursion, as it were, since the black shale all told does not exceed 2 feet in thickness. The fact that the eurypterids are often dismembered and their parts distributed over considerable areas, and that a dozen or more are frequently found side by side, with a com- mon flexure, suggests that they may have been drifted up by a current. On the other hand, the fine preservation of much of the material, extending even to the delicate appendages, shows that the currents were very weak, thus practically leav-. ing the animals in the position of death or molting. Their grouping is very probably due also, in some degree, to their gregarious habits or to their abundance. The tests of the eurypterids are black and carbonized. A line of dehiscence around the anterior edge of the cephalothorax indicates that in many cases these remains are moltings. REPORT OF THE STATE PALEONTOLOGIST 1902 1087 DISCUSSION OF SPECIES Genus HUGHMILLERIA gen. nov. By far the most abundant of the eurypterids occurring in this stratum of black shale near the base of the Salina, is a small form which, from its general appearance, in many ways suggests the genus Eurypterus, while a study of its structure shows it to be closely related to Pterygotus. It is evidently a new genus, which it is proposed to designate by the name Hughmilleria. Generic diagnosis General outline lanceolate. Cephalothorax semielliptic and flatly convex; compound eyes small, subelliptic and marginal; ocelli subcentral. Abdomen divided into distinct.anterior and posterior regions. Preabdomen provided dorsally with six plain, transverse, bandlike tergites; ventrally with five stern- ites, the last three being essentially like the corresponding dor- sal plates. First sternite cleft for the reception of a median appendage, which varies in form according to sex. Basing sexual distinctions on the determinations made by Holm in Eurypterus fischeri, this appendage in the female consists of a narrow, convex, scalelike, sagittate-based sheath, which appears to be formed by the fusion of two nearly equal portions, the anterior overlapping, and projecting poster- iorly to cover partially a slightly shorter, simple, lance-linear ap- pendage in a cleft of the following sternite. In the male the appendage is confined to the first sternite, the second being en- tire. It is proportionately shorter and broader, convex and lanceolate with the posterior free end slightly produced. Post- abdomen composed of six ring segments. The first is readily distinguished from the segments of the preabdomen by post- lateral prolongations. It appears to be formed by the fusion at their appressed end@ of a sternal and a tergal portion, the latter of which is the longer. The following segments are sim- ple, bandlike rings. Telson long, lanceolate, with dorsal carina- tion. Epistoma convex, peltiform, dividing in molting or under Stress of compression, through the middle, joined at the sides to a narrow doublure. Preoral appendages attached at the pos- 1088 NEW YORK STATE MUSEUM terior end of the epistoma; short, stout, composed of three joints, the two distal a little shorter than the basal, and forming a pair of edentulous, bevel-edged pincers, which normally are folded back so that their tips converge close to the anterior end of the mouth. Endognathites increasing in length from the first back- ward, moderately robust, spiniform, composed of seven joints, of which the third to the sixth inclusive bear a pair of spines. Swimming arms narrow, lanceolate paddles, composed of eight joints and a rudimentary ninth inserted in a notch on the inner side of the eighth or palette. The proximal joint, or gnathobase, has the form of an upright retort. The seventh bears on the inner half of the distal end a subtriangular lobe demarked by a suture. Metastoma elongate, cordate. Type, H. socialis Sarle. Comparison with other genera The characters suggesting Pterygotus are: the rounded tri- angular or semielliptic outline of the head as seen in Pt. banksii Salter (8) and Pt. raniceps Salter (8); the marginal, compound eyes; the slender body with slight constric- tion between the anterior and posterior abdominal portions; the cordate form of the metastoma; and the simplicity of the opercu- lar plate and its appendage. The two forms of this append- age resemble those of Pterygotus as far as the material of the latter permits of comparison, one form being a slender, sagittate-based scale, the other a shorter, broader, convex body, asin Pt. bilobus Salter (11) and Pt. osborni Hall (10). In the new genus the first form projects posteriorly to protect a shorter lance-linear appendage lying in a cleft of the second sternite, while the second form is followed by an entire sternite without appendage. The sixth pair of cephalothoracic appendages resemble those of Pterygotug, in being only slightly expanded distally and consisting of eight joints, with a rudi- mentary ninth inserted in the end of the palette. The gnatho- bases have the upright retort form. This genus is distinguished most clearly from Pterygotus by the character of the preoral appendages. These are stout, three- / REPORT OF THE STATE PALEONTOLOGIST 1902 1089 jointed, chelate organs, so short that when extended they barely equal one half the length of the cephalothoracic shield. The pincers are edentulous and bevel-edged and in their normal posi- tion lie folded over the basal joints so that their tips converge close to the anterior border of the mouth. Extended, these organs project beyond the border of the shield for perhaps half their length; when turned straight back, their tips lap over the end of the metastoma. In Pterygotus, on the contrary, these organs are very long, having, at least in Pt. bilobus Salter and Pt. macrophthalmus Hall, a length fully one third that of the entire animal; and consist of ponderous, dentate pincers supported on a slender, retrally tapering proxi- mal joint of such a length as must necessarily have prevented the pincers being used at the mouth, unless these appendages were somewhat retractile, as suggested by Laurie (9). The next important difference is in the character of the spini- form walking legs. As in Pterygotus, these consist of seven joints, but the several pairs present a greater contrast in their respective lengths, are proportionally more robust, and each joint from the third to the sixth inclusive, carries a pair of ven- trally and distally articulated, slender, curved spines. It is doubtful if any species of Pterygotus has spines on these ap- pendages; certainly, in several species in which these limbs have been found apparently well preserved, they are lacking. Woodward (8) represents Pt. taurinus Salter as having a spiniferous endognathite. Laurie, in his Anatomy and Rela- tions of the Hwrypteridae (9), in one ptace states that there is no elaborate development of spines on the endognathites of Pterygotus. Earlier in the same paper, however, he makes the statement that they are destitute of anything in the way of spines and, in a comparison of the appendages of Slimonia with those of this genus, offers this explanation: “These [dentate, preoral] appendages, unlike those of Slimonia, were probably prehensile rather than masticatory, and this function may account for the absence of spines on the other limbs (en- dognathites), which are purely ambulatory.” The converse of this may be stated of Slimonia, and also of Hughmilleria, since \ 1090 NEW YORK STATE MUSEUM the pincers are edentate and the walking limbs carry light, claw- like spines. The epistoma, instead of parting on either side from the doublure by stress of compression or in molting, as an epistoma of Pterygotus figured by Laurie (9) did, is seen to have divided through the center, an occurrence observed in a large number of specimens. Schmidt (12) figures an epistoma of Pt. osil- iensis Schmidt, which, while showing a tendency to divide along sutures at the sides, has also a deep open cleft in the posterior edge. It is evident that there is considerable varia- tion in this plate in different species. The last of the differences lies in the telson, which is slen- derly lanceolate and much longer than that of any known species of Pterygotus. Regarding its resemblance to Eurypterus, it might be said that, but for the marginal position of the eyes and relatively large chelae, this form would easily be mistaken for a species of that genus. The semielliptic form of the head and the slight expansion of the swimming arms, recall E. lanceolatus Salter (8), and the slender telson gives the posterior part of the body of a general Eurypteruslike appearance, hightened by the spiniferous character of the walking legs and the short, edentulous, masticatory preoral appendages. However, the walking legs are less robust. They consist uni- formly of seven joints and are equally spiniferous, while in Eurypterus, with the exception of the first pair, there are more than seven, and the fourth pair carries merely the three end spines. In the preoral appendages, the basal joints, instead of being flat expansions on which the pincers are articulated (15), are segments a little longer than the pincers, which, in their normal position, instead of hanging down over the mouth, do not quite reach its anterior end. These pincers have been seen in Eurypterus only in the Russian species E. fischeri. The limbs of the sixth pair are less expanded at the ends than is usual in Eurypterus, and have narrow, upright, instead of heavy, subquadrate gnathobases. The operculum is simpler, lacking the faint transverse suture and two subtriangular REPORT OF THE STATE PALEONTOLOGIST 1902 1091 areas which in the female Eurypterus lie in front, one on either side of the median suture. The parts of the genital appendages correspond in a general way to those of Eurypterus, though there is considerable difference in their form. In the female the appendage consists of two parts, one carried by the ' operculum, the other by the following sternite. The part car- ried by the operculum is slender with a sagittate base, and is divided transversely into two portions, but lacks the pair of short, flat, diverging, terminal crura. That carried by the sec- ond sternite is simple, broader at the base and attenuated at the distal end, instead of having articulated to it, two diverging, ensiform strips (14). In the male, as in Eurypterus, the ap- pendage is confined to the operculum, and is shorter and broader than that of the female; but is proportionately larger than in that genus. The genus Slimonia is suggested in three ways: by the mar- ginal position of the compound eyes, by the shortness and edentulous character of the masticatory preoral appendages, which are, however, less robust in that genus, and by the length of the telson and the slight indication of inflation in the an- terior portion. In other respects there appears to be consider- able difference between these genera. From a consideration of the foregoing facts, it appears that Hughmilleria is most closely related to Pterygotus. With Pterygotus and Slimonia, it makes three genera of eurypterids having the compound eyes marginal. In development of preoral appendages, it comes between Pterygotus and the other genera in which these appendages are known, including Eurypterus, Dolichopterus, Stylonurus, Eusarcus and Slimonia.

Viewed from either the dorsal or the ventral side, the outline is slenderly lanceolate. In the natural, undistorted condition, the anterior part of the body is flattened, the dorsal and ventral surfaces being slightly con- vex, while the caudal portion is nearly cylindric. ~ 1092 NEW YORK STATE MUSEUM Cephalothorax. The cephalothorax is semielliptic or subtri- angular in outline, the length equaling the breadth at the base, and comprising about one fifth the length of the entire body. Along the gently curving sides and acutely rounded front is a narrow flattened border, striated on the under surface, and not exceeding a fraction of a millimeter in breadth. The dorsal sur- ~ face is slightly rounded or arched from the side to the center, so that in an undistorted shield 22 mm long, the elevation is about 2mm. The posterior edge, except for a slight forward curve at the genal angles, is straight. The compound eyes barely break the outline of the shield; they are small, elongate, widest anterior to the middle, the outer side arcuate, the inner formed by three nearly straight edges—a short basal and a little longer anterior, forming slightly rounded obtuse angles with a long inner side. The anterior end of the eye is acute. The length of these organs on the cephalothorax, the dimensions of which were given above, is 5 mm. However, the usual proportion between the length of the shield and eye is as 1:4.5. A line drawn connect- ing the posterior ends of the eyes passes through the center of the shield. The ocelli are situated on a small tumescence cut by this line; they form two minute, ringlike prominences sepa- rated by about the length of their diameter. Abdomen. The abdomen, at the widest point, or between the third and fourth dorsal segments, is a little wider than the base of the cephalothorax. Thus, in one animal measured, these dimen- sions were respectively 24 mm and 17.5 mm, in a second 23 mm and 17 mm, and in a third 33 mm and 26 mm, probably varying somewhat according to the amount of compression and also somewhat with the animal. From this point the abdomen tapers very gradually to the telson; it is divided into anterior and posterior parts, easily distinguished by their structure. The preabdomen consists of six dorsal and five ventral, trans- verse plates; the postabdomen of six annulate segments and one spiniform. Preabdomen. The first tergal plate of the preabdomen is very narrow and is overlapped by the posterior margin of the shield. Its posterior edge is slightly convex, and its ends are rounded. REPORT OF THE STATE PALEONTOLOGIST 1902 1093 The second segment is twice as long as the first, its posterior edge is slightly concave along the middle portion, and the posterior angles are rounded, while the anterior are produced, to make up, as it were, for the rounding away of the preceding tergite. The succeeding tergites are very nearly equal in length, the fifth being perhaps a little the longest, and are about one third longer than the second. The posterior margins are concave as in the preceding, but straighter near the sides, forming almost right angles. The first ventral plate, or sternite (the operculum), is: one third as long as broad, and is divided along the axial line into two equal parts. These are rounded off at the lateral angles, particularly the anterior, and excavated along the median line for the reception of the opercular appendage; the posterior edges are slightly projected on either side of this, while the anterior inner angles are projected forward, forming a com- pound median lobe. The second sternite, in the female, is nearly as long as the operculum, and is deeply cleft for the reception of an appendage nearly equal to it in length. The sides are cut obliquely forward, making the posterior angles rather acute;: the anterior angle forms small lobes, and the middle of the anterior edge is slightly produced. In the male the last four ' sternites, and in the female the last three, do not differ mate-. rially from the last four and three abdominal tergites. The relative position of the several plates of the sternal series to. those of the tergal, is as follows: the opercular plate begins a little farther forward than the first tergite, but, owing to its. greater breadth, lies beneath the line of overlap of the first and second tergites, while the second sternite lies beneath the over- lap of the second and third tergites, and so on, the last sternite underlying the overlap of the fifth and sixth tergites, thus not extending as far back as the posterior edge of the sixth tergite. Postabdomen. The first postabdominal segment consists ot a tergal and a sternal portion united by their appressed pleural ends. The postlateral angles are prolonged into short, bladelike lobes which extend alongside the following segment for fully half its length. The tergal portion is the longer, \ 1094 NEW YORK STATE MUSEUM and its posterior edge forms a broad lobe; the sternal portion is short, and its posterior edge is straight, while its anterior edge extends forward to meet the last sternite of the preab- domen. The following five segments are plain, bandlike rings, decreasing in breadth backward. In the first the breadth is considerably greater than the length; in the last, or penultimate body segment the length and breadth, in compressed specimens, are equal. The anterior end of each of these segments is marked by a groove for the attachment of the interarticular membrane. | The telson is very slenderly lanceolate, widest near the an- terior end and attenuated at the tip. In length it is equal to the four preceding segments. The dorsal surface is convex, rising from sharp, lateral edges to a median longitudinal carina, which begins in the anterior part as a broad, angular promi- nence; the ventral surface is nearly flat or faintly convex; a cross section is thus subtriangular. Compression usually flattens the sides and thus hightens the angular appearance. The uncompressed specimen [pl. 15, fig. 6] has a length of 31 mm and a greatest breadth of 7 mm. On the ventral surface of the cephalothorax, in front, is a convex lobe or platform, the epistoma, from which extends a flat, tapering doublure ending in a small expansion at the genal angles [pl. 11, fig. 6 and pl. 12, fig. 2]. Im molting and also from compression, the epistoma divided through the middle rather than along the sides [pl. 12, fig. 2]. Appendages. The preoral appendages are short, stout, three jointed, chelate organs attached at the posterior border of the epistoma [pl. 11, fig. 7]. The two distal joints of each form a -pair of broad based, edentulous, bevel-edge pincers, in the ordi- nary state of compression having a breadth equal to one half the length. The blades are about equal in length to the basal por- tion and meet at the very acute, slightly curved tips and again, usually, only near the base. There is considerable variation in the relative form of the pincers, as shown on plate 11. The broad basal joints are about one fourth longer than the pin- cers, widest near the base and longest on the inner side, and in REPORT OF THE STATE PALEONTOLOGIST 1902 1095 the natural position extend beyond the anterior margin of the shield for about one third their length. The pincers articulate with this joint in such a way that, when folded backward, they cross it obliquely, and their tips converge a little in front of the mouth; when extended forward, they diverge somewhat. The preoral appendages could also be turned back to their full length over the mouth, the pincer tips then overlapping the metas- toma [pl. 11, fig. 6]. In an individual having a cephalothorax 22 mm long, the preoral appendages are 10 mm long. (Plate 9, figure 1, shows these organs from the dorsal view, the cephalo- thorax having been removed.) The four pairs of endognathites, or crawling legs, do not differ materially from one another except in length. The anterior limbs are somewhat shorter than the extended preoral ap- pendages, and their tips extend but very little beyond the margin of the shield. Each succeeding pair is about one half longer than the preceding, so that the last limbs are probably four times as long as the first. All have seven joints, of which the terminal is spiniform. The third to the sixth joints inclusive carry ventrally and at the distal ends a pair of striated, slightly curved, slender spines. The inner spine of each pair is the longer, and the length increases for each successive set, from the third to the fifth joints; the spines on the sixth are short. The coxal joints are elongate, slightly curved, widest at the base and equal in length to the succeeding two joints. They increase in length with each successive pair, and bear on the inner end a series of 15 or more, sharp, curved teeth, which de- crease in size from the front. On each of the fourth coxal joints is a large perforation of the upper side near the fixed end [pl. 26, fig. 5]. No epicoxite has yet been observed. The second joint of the endognathite is divided by constrictions into three transverse sections. It is articulated at the fixed end of the coxal joint and is fully two thirds as wide. The limbs of the sixth pair are narrow and paddlelike, and con- sist of eight joints and a rudimentary ninth or claw, the seventh and eighth forming a slightly expanded blade. The seventh car- ries a large, subtriangular, lobelike plate, nearly one half as 1096 NEW YORK STATE MUSEUM long as the joint proper, marked off from the inner, distal end by a suture. The eighth, or palette, is elongate oval with the margin finely incised, and carries the minute claw inserted in a notch on the inner side near the tip. On the dorsal surface of the seventh and eighth joints, at the proximal end and outer edge of each, is a group of minute, craterlike tumescences, which were probably receptacles for the bases of hairlike bristles [pl. 14, fig. 8]. In a swimming arm 29.5 mm long, exclusive of the gnathobase, the narrowest joint or the fourth, measures 5 mm across; from this point the arm gradually enlarges to 6.8 mm on the seventh and eighth joints. When the swimming arms are turned back, they reach the line of the fourth or fifth dorsal segment. The gnathobases have the form of an upright retort. The inner extremity of each is provided with from 18 to 20 sharp, slightly curved teeth, which become finer posteri- orly. A gnathobase, accompanying a cephalothoracic shield 22 mm long, is 16 mm long; the width of the narrow necklike portion 6 mm; the width at the base 13 mm. The metastoma is elongate cordate, the greatest breadth com- ing anterior to the middle. The smaller, or posterior end, is truncated and has rounded corners. The anterior notch is rather deep and broad. A comparison of the length to the greatest breadth of several metastomas gives the proportion of 2:1. In an individual having a cephalothorax 23 mm long the metastoma is 16 mm long. The genital appendage differs noticeably in the two sexes. In the female it consists of two parts, one carried by the operculum, the other by the second sternite [pl. 13, fig. 1, 2]. The opercu- lar appendage is a slender, sagittate-based, convex, scalelike sheath projecting for about one fifth its length beyond the posterior edge of the operculum and appearing to be formed by. the fusion of two parts. The anterior of these includes the sagittate base and a narrower, more convex portion with a flattened border on either side [pl. 18, fig. 4]. Its distal end is reentrant [pl. 24, fig. 1] and fused to the posterior part. This part is a little narrower, slightly tapering and beveled in from either side for one fourth the breadth, to the sides of a slightly raised platform which is flat topped for the greater part of its _—” REPORT OF THE STATE PALEONTOLOGIST 1902 1097 length, but becomes concave posteriorly, forming a shallow groove at the abrupt end. The terminal angles are noticeably truncated. The appendage carried by the second sternite is par- tially covered by that of the operculum [pl. 14, fig. 2]. It is very slender, its greatest breadth not exceeding one sixth the length [pl. 26, fig. 3; 18, fig. 4]. The anterior half is sublanceolate with a triangular base; the posterior is attenuate and termi- nates just within the end of the cleft. In the male the ap- pendage is simpler and confined to the operculum, the follow- ing sternite being entire (pl. 13, fig. 3]. It is wider and some- what shorter than that of the female, the average length being only about two and one half times the breadth. It is convex, broadly lanceolate and slightly produced at the posterior free end which just clears the edge of the operculum. A specimen in which a portion of this organ is scaled away [pl. 14, fig. 1] gives a cast of the interior showing small elevated lines radiat- ing from near the center backward, and may possibly represent part of the vascular, or duct system of this organ. The two sexes are about equally represented in numbers. The whole surface of the body is covered with imbricating, crescentlike or angular scales, sometimes carrying smaller ones of the same pattern. These scales are so minute on certain areas as to appear almost obsolete. They are most con- spicuous on the ventral side of the preabdomen and appendages. On the cephalothorax and abdomen the scales point backward, on the paired appendages toward the distal end, and on the epistoma, forward. | Hughmilleria socialis var. robusta var. nov. Plate 21, fig. 1, 2 What appears to have been a varietal form of Hughmil- leria socialis is represented by a nearly entire abdomen, two first ring segments and an imperfect metastoma. The features which distinguish this form are: its larger size; proportionately much greater breadth; the greater convexity of the dorsal posterior edge of the first ring segment and, in some cases, the division of this edge into two, broad, smooth lobes; the more noticeable contraction of the abdomen at the 1098 NEW YORK STATE MUSEUM second ring segment; and the more rotund form of the metastoma. The abdomen found lies in the shale dorsal side up, showing the anterior nine segments well preserved. The second and third ring segments are partially disconnected. The breadth of the preabdomen at the widest point, or between the third and fourth segments, is 51mm, its length 56 mm, the breadth of the first ring segment is 42 mm, of the second 30 mm. The dorsal posterior edge of the first ring segments is entire and very noticeably convex. In each of the isolated ring segments a broad, deep notch produces a bilobation of this edge. A line of pittings close to this edge shows this feature to be natural. The proportions of the more perfect of these segments are: breadth 43 mm, length of the dorsal side 22 mm, length of the ventral 11 mm, length of the postlateral lobes 8 mm. The metastoma associated with one of these segments is apparently of a smaller individual and lacks the anterior notched end. At the widest part it measures 14 mm and, from there to the posterior end, 14 mm. It was at first thought that the distinctive features of these specimens might be merely old age characters of H. socialis, but larger individuals of that species seem to show the same relative proportions'as the smaller. However, it is considered that the differences shown by the incomplete material of the collection are not, of themselves, sufficient to warrant the found- ing of a distinct species. Genus EURYPTERUS DeKay. 1825 Eurypterus pittsfordensis sp. nov. Plate 10, fig. 7; 15, fig. 1-3; 16-23; 24, fig. 2-5; 25, fig. 2, 5, 6 This species is comparatively rare and is not represented in: the collection by any entire individuals. There is however sufficient material to enable its main features to be correctly determined. The entire animal is large and robust, and broadest at about the third segment. The cephalothorax is two thirds as long as broad, eyes of medium size, appendages heavy. The pre- abdominal and postabdominal portions are not strongly differ-- REPORT OF THE STATE PALEONTOLOGIST 1902 1099 entiated; the telson long, probably equal in length to the five preceding segments. The cephalothorax is broad, rounded in front, the sides curving out near the genal angles, and the base straight, or very gently curving over the middle portion, and extending a little forward near the sides. The margin is beveled in for a distance, in the average sized individual, not exceeding 2 mm in the widest part or in front, narrowing and fading out at the genal angles. The extreme edge is slightly upturned. The com- pound eyes are separated by one half the breadth of the shield, with their bases in line with its center. They are prominent, reniform, broader at the anterior ends, and one fifth as long as the shield. The ocelli are situated on a faint tumescence between the centers of the compound eyes. They are rather large and separated by about their own diameter. Near the basal edge of the shield is a pair of sharp, raised, triangular scales, one on either side of the axial line. In some cases there is a row of shallow, flat bottomed pits on the beveled margin. The abdomen increases slightly in breadth from the base of the cephalothorax to the third segment, then tapers to the telson, there being no apparent constriction between the pre- abdomen and postabdomen. Tbe tergites are comparatively short, the length averaging a little less than one fifth the breadth. They are broadly concave along the middle of their posterior edges, and each carries, bordering this curve, four raised, triangular scales like the two on the posterior border of the cephalothorax and the middle two in line with them. The five sternites are medially cleft and marked by transverse Sutures, which give to each the appearance of having been formed by the fusion of two plates. With the exception of the first or operculum, they have the anterolateral angles projected forward into small lobes. In the operculum these angles are noticeably rounded away, and the anterior edge is projected into a broad median lobe. In the female the second sternite has a similar lobe. The annulate segments, or sclerites, com- prising the postabdomen increase in length and decrease in breadth from the first, which is very broad and short, to the 1100 NEW YORK STATE MUSEUM Jast in which the length exceeds the width of the anterior or wider end. They are depressed and have faintly defined pleural areas or flattenings at the sides. Each is prolonged on either side, at the posterior angle, into a short, striated spur, which grows longer with each succeeding segment, those on the last forming conspicuous pointed lobes. The first two segments each carry on the dorsal side four triangular scales like those of the preabdomen, the third, fourth and probably the fifth, each two, the last none. This segment has a shallow notch in the middle of the dorsal, posterior edge, marked on either side by a small denticle, succeeded toward the sides by very minute ones. The series of striations of the lobes continue up the sides of the segment to its articulation with the preceding. On the ventral portion of each ring segment is a shallow posterior emargination fringed with lobelike teeth. Extending forward from near either end is a curved rent, a pair sometimes almost inclosing an irregular, oval area. The telson is very long, nearly equaling in length the rest of the postabdomen. For a short distance from the anterior end it contracts rapidly, then continues slender to the abruptly rounded point. The edges are sharp and, from near the anterior end, are marked by short, oblique incisions. The dorsal surface is smoothly convex, the ventral has a flat topped carina which begins near the proximal end and extends to the tip. On the carina is a double row of pits like those bordering the cephalothorax. The doublure, at its dehiscence in the axial line, equals in width about one fourth the length of the cephalothoracic shield. From this point it narrows toward the genal angles. The preoral appendages have not been observed. The endog- nathites are robust and vary greatly in length, the first pair being barely long enough to reach the shield border, while the members of the third clear it by fully three fourths their length. The fourth pair is known only by a coxal joint and a basal por- tion consisting of three joints. The first legs consist of seven joints; the second and third each, of eight. In the first three, each joint from the third to the penultimate is provided with ———— - - REPORT OF THE STATE PALEONTOLOGIST 1902 1101 two long, curved, striated spines. The terminal joints are com- paratively long and clawlike. The coxal joints are large. The first three are short and broad, the length being a little less than two thirds the breadth. They have narrow, curved, postlateral prolongations equal in length to the second joint. The lower, inner angles are rounded and crenulated. The dentate faces at the inner, upper angles are on slight prolongations, which grow longer with each succeeding coxa. All three begin with two or three isolated, anteriorly directed, lobelike teeth, followed by slender conic ones, which become finer toward the posterior end. The fourth coxal joint is comparatively long. The inner lower angle is gently rounded away, and the neck supporting the narrow dentate face, long. The teeth appear to be compara- tively few and coarse. The epicoxite of the third left coxa is shown on plate 16, figure 1. The swimming arms are stout and moderately long, extend- ing back nearly to the fifth tergite, and consist of nine joints. The gnathobases are subquadrate and large, and are provided with seven or eight short, bevel-edged denticles, the two anter- ior being large and prominent. The length of the gnathobase [see pl. 15, fig. 1] was 33 mm, its breadth 30 mm, the length of the dentate face 8 mm. The middle joints have the anterior and posterior angles sharp, in the fifth the anterior forming a blunt, striated spine, much like those at the sides of the postabdomen. The seventh and eighth joints are broadly expanded, and their margins, particularly in the latter, are marked by sparse, shallow serrations. Inserted on the inner side and near the end of the eighth joint, is a small, oval, rudi- mentary ninth joint. The metastoma is elongate ovate, widest in the middle, with ends truncated. The anterior or narrower end is notched and minutely dentate. The genital appendages of this species, so far as they are pre- served in the material of the collection, are, with the exception of the part carried by the second sternite in the female, essentially like these of E. fischeri Eichw., as described by Holm (13). That of the female is the more complex and is carried partly by 1102 NEW YORK STATE MUSEUM the operculum and partly by the second sternite. The part car- ried by the operculum follows two subtriangular areas formed by a pair of sutures extending posteriorly from either side of the median lobe to meet the cleft, and extends considerably beyond the posterior edge of the plate. It consists of a short sagittate base and a slender portion divided transversely into two im- bricating sections, each terminating in a short bifid expansion [pl. 24, fig. 5]. In E. fischeri there is a third part consisting of two, short, flat, diverging crura. As this appears to be a general feature in Eurypterus, it is probable that it exists in this species also. The part of the appendage carried by the second sternite is covered by that of the operculum. It lies in the median cleft which extends through the posterior two thirds of the sternite, the anterior third of the two halves of this plate being fused [pl. 25, fig. 5]. It is slender, being about one fourth as wide as long and does not quite reach the posterior edge of the sternite. The anterior end is slightly constricted where it fuses with the sternite, and the distal is taper- ing. The male appendage is confined to the operculum. In the material of the collection is a single specimen showing [pl. 25, fig. 2] the exterior, the others showing the internal form only. It was evidently small, about one fifth the length of the operculum by which it is surrounded. The body is covered with comparatively coarse, imbricating, crescentic scales, most distinct on the sternites and swimming arms. When the integument of the metastoma and paired ap- pendages are scaled away, there remains a punctate surface. The specimens found show that the size of these animals aver- ages from 20 cm to 30 cm. A fragment of the third joint of a swimming arm was found, however, which appears to have been part of an individual over 60 cm in length. Genus prerycorus Agassiz. 1839 Pterygotus monroensis sp. nov. Plate 24, fig. 7, 9 This species is founded on a single specimen, a cephalo- thoracic shield. The outline of this shield is semielliptic with REPORT OF THE STATE PALEONTOLOGIST 1902 1103 the posterior edge noticeably incurved. The surface is moder- ately convex, and along the sides and front is a threadlike border. The length of the shield, without the genal angles, is 30 mm, with them 37 mm; the breadth at the base 88 mm. The compound eyes are prominent and project beyond the outline of the shield. They are subelliptic, with a distinct angulation on the inner side of each, produced by an indentation of the inner anterior part. They are 14.5 mm long and 6 mm wide. The facets can be made out with a good magnifying glass. The eyes are located a distance equal to their own length from the front of the shield and 27 mm from each other. A line connecting their bases cuts the axial line a little back of the center of the shield. The ocelli are on a small tumescence just back of this. The ornamentation is almost obliterated, but can be made out at one point, where it consists of minute, short, flat, lobelike scales. Out of the eight species of Pterygotus that have been de- scribed from American strata, and all from the Bertie water- lime, the cephalothorax of but one has been identified, that of P. macrophthalmus Hall (10). Pohlman (14) described and figured one, but did not refer it to any species. It seems probable that it is of an older individual of P. macroph- thalmus. The cephalothorax of this new species differs from that of P. macrophthalmus in that its length is nearly equal to its breadth; the compound eyes are over one third the length of the shield, elongated, angulated on the inner side, situated farther back, and separated by nearly twice their length. In P. macrophthalmus (15) the length of the shield is three fourths the breadth; the eyes are about one third the length of the shield, anterior, globular and separated by a distance about equal to their length. In form the eyes of this species suggest those of the erettop- terid species (subgenus Erettopterus Huxley), P. bilobus Salt. and P. banksii Salt. and also those of H. socialis. 1104 NEW YORK STATE MUSEUM Fragments of Pterygotus Plate 24, fig. 6, 8 In addition to the cephalothorax described above, other parts were found, mainly mere fragments, having the coarse, scaly orna- mentation of Pterygotus, but even the more perfect can not be referred to definite species. because of their isolated condi- tion. Among these is an ovate metastoma [pl. 24, fig. 8] 27 mm long and 16 mm wide, broadest just anterior to the middle, with the anterior corners slightly truncated, the lobes small and the terminal notch very narrow and shallow. It is marked by coarse, rounded, lobelike scales and is very much more robust than would be expected in Pterygotus mon- roensis. Judging by the ornamentation, it should be asso- ciated with the coarse scaled fragments most frequently found. The broken, free ramus of a chela of a Pterygotus is repre- sented on plate 24, figure 6. , The shaft is nearly parallel sided, 3 mm broad and 12.5 mm long and curves at the end into a stout, striated, nearly perpendicular mucro 3.5 mm long. Back of this mucro is a series of 10 erect, subtriangular, striated denticles, very slightly separated at their bases. They are of three sizes, the largest or primaries being about one half the length of the mucro, the secondaries one half that of the pri- maries and the tertiaries about one half that of the secondaries. The first primary is separated from the mucro by a secondary and from the second primary by two secondaries and two ter- tiaries alternating; following the second primary are two sec- ondaries separated by a tertiary. The free ramus of Pt. buffaloensis Pohiman (14) differs from this in having the shaft convex on the inner side; the teeth perpendicular, numerous, acute, varied in length, one or two longer ones about midway in the series; and the mucro set at an acute angle. In P. cobbi Hall (10), the only other species of the Water- lime in which this ramus is known, it is many times larger than this fragment; shaft tapering; mucro less erect and blunt tipped; teeth six, comparatively short, strong and unequal. Another fragment [pl. 24, fig. 1] represents the basal part of the long, tapering, proximal joint of a chela of a Pterygotus. REPORT OF THE STATE PALEONTOLOGIST 1902 1105 These fragments show the venus Pterygotus to be fairly wel} represented in the black shale by species, though not by num- bers. Genus (?) Plate 26, fig. 1, 2, 4 An eurypterid differing very materially from anything de- scribed from the Bertie waterlime, is represented in the collec- tion by a group of four incomplete arms and a body segment, and by another of two incomplete arms. In the first group [pl. 26, fig. 2] the longest of the arms has the coxal and succeeding five joints preserved. These are long, measuring altogether 110 mm in length. The three distal bear a series of long, curved spines. The form of the coxal joint is subtrapezoidal, the anterior side being considerably the longer. The breadth and the mean length are each about 18 mm. The dentate border is slightly produced and in length is equal to about one half the breadth of the joint. The denta- tion begins at the front end with an isolated, blunt tooth point- ing forward, followed by sharp, curved teeth of small size which grade posteriorly into fine, hairlike bristles. The anterior side of each joint from the second to the sixth inclusive, is arcuate. The posterior sides of the second and third joints are straight, of the fourth, fifth and sixth, concave. The distal end of each is at right angles to the long axis. The second joint is nar- rower (14.5 mm) than long (23 mm); the third just twice as long (28 mm) as wide (14 mm); the fourth a little longer than the preceding (80 mm) and less than half as wide (7 mm). Along the concave, posterior side of the fourth are articulated five, long, curved, striated spines, nearly perpendicular to the joint. At the distal end of the series there is an indication of another. The most complete of these spines is 16 mm in length. The. fifth joint is 16 mm long and 6 mm wide. Near the anterior end of the posterior edge it carries the stump of a large spine fol- lowed by the sockets of four more. The sixth joint bears the basal portion of three spines, but is so crushed and fore- shortened that neither the original number of spines nor the length of the joint can be determined. Judging by the taper of this arm, there may have been two more joints. 1106 NEW YORK STATE MUSEUM The remnant of another appendage appears to be part of the proximal four joints, and measures 32 mm in length. From its robustness, it seems to have belonged just in front of the last mentioned. The peculiarities of these joints are their shortness and their thickening at the articulations. The joint, which on the tablet lies nearest to the large arm, is a little inflated and, though very imperfect, has the appearance of being the coxal joint. . The two other appendages of this group are robust and short. One is tolerably complete, apparently lacking only the dentate border of the coxal joint. It is 38 mm long and consists of seven joints. The coxal is large and globose. Each joint from the second to the fifth carries on the posterior edge a pair of short. stout, distally directed, lanceolate spines, averaging 2.55 mm long and nearly half as wide. Joint two is broad and very stout. Joints three, four and five are subquad- rate and successively smaller. Joint six is nearly one and one half times as long as broad and at the end bears two dis- tally directed spines, one anterior, the other posterior. The seventh is long and clawlike, slightly inflated at the base. The other appendage is so crushed and folded that little can be determined by it. However,.from the larger size of the coxal joint, it is probable that its position on the body was behind the more complete. The spines preserved on it, like those of the smaller appendage, are short and lanceolate. The body plate in this group is very narrow (76 mm) as com- pared to its length (283 mm). Its division into right and left halves by a suture, the arching of each half and the produced anterolateral angles indicate it to have been a paired sternite. In the second group one of the imperfect arms consists of the four distal joints, the other of two imperfect proximal joints. The joints of the former are short and expanded at the articula- tions. The first and second are each provided on the posterior side with a pair of distally directed spines. These are long, curved and sharp like those of the large arm of the other group. The second has also, on the opposite side of the distal angle, a single, large one extending parallel with the axis of the arm. The penultimate is long and shows no sign of having been REPORT OF THE STATE PALEONTOLOGIST 1902 1107 spiniferous. The terminal is about equal in length to the spines and, like the terminal appendage in the other group, is clawlike. This arm, judging from the shortness of the joints and the broad- ening at the articulations, probably corresponds to the second described from the other group. The joints of the other arm appear to correspond to part of joints two and three of the first of that group. Associated with this last, and lying partially beneath its larger end, is a fragment of test which is ornamented by sharp, © triangular scales differing from anything found on the other eurypterids herein described. However, it is not certain that this had any connection with this arm. Aside from this possi- bility, neither the appendages nor the sternite show any signs of ornamentation. The most noticeable features revealed by these specimens are: the robustness and the great difference in size of the several pairs of endognathites; on the anterior three of these, the arrangement in pairs of the posterior spines, which, on the first two, are noticeable for their shortness and lanceolate form, and on the third for their length and curvature; the high degree of specialization of the fourth pair of endognathites, shown by the great length of the joints and the number and large size of the spines; the narrowness and proportionately ereat Jength of the compound sternite; and the probability of there being several compound sternites. It is evident that the animal had a long, slender body with long, very strong limbs. From a comparison of these parts with those of the various genera of eurypterids, it appears that they do not agree very closely with any. To show this, it is necessary only to point out certain of the more evident differences. In Eurypterus proper the fourth endognathite, to which I consider the longer of these arms to correspond, consists of nine joints, probably a greater number than is possessed by the other; besides, it bears no spines except the two formed by the prolongation of the eighth or penultimate joint. On the three anterior pairs of endognathites the spines are more uniform in shape and 1108 NEW YORK STATE MUSEUM size. The body is proportionately broader and shorter than that indicated by the sternite described above. In eurypterids of the typeof Eusarcus scorpionis Groteand Pitt (15), Carcinosoma newlini Claypole (16), Echinogathus clevelandi Walcott (4), Eurypterus punctatus Salter. E. scorpiodes Woodward (8), E. secoticus Laurie (17), etc., so far as material shows, the preabdomen is obese, the second pair of endognathites is the longest, and _all four pairs with their spines are curved forward. In Sty- lonurus and the related genus, Drepanopterus (17), the fourth endognathites are without any elaborate development of spines. and in the former are greatly elongated. In Slimonia*the first pair of endognathites is tactile, the succeeding three pairs are short, vary little in size and are all provided with small spines at the distal ends of the joints. In the Pterygotus the four pairs of endognathites are filiform, of nearly equal size and probably in all cases, spineless. It seems quite probable that, with more perfect material, this form will be found to represent a new genus. References 1 Whiteaves. Palaeozoic Fossils of Canada, v.3, pt}. 1884 2 Hall & Clarke.

PRELIMINARY OBSERVATIONS ON THE COBLESKILL (“ CORALLINE ”) LIMESTONE OF NEW YORK BY C. A. HARTNAGEL More than 50 years ago Professor Hall’ described a fauna obtained from a thin mass of limestone outcropping near the base of the Helderberg at Schoharie N. Y., which, on account of its great abundance in corals, had become known as the Coralline limestone. This is the lowest of the many limestone formations in the vicinity of Schoharie. In its western extension it was traced by its characteristic fossils as far as Herkimer county. From the paleontologic and stratigraphic evidence furnished by the study of this limestone and also from a similarity in litho- logic features, Hall concluded that the “ Coralline” represented the attenuated eastern extension of the entire Niagara group as it then was known in western New York. The evidence for corre- Jation furnished by the 25 species of fossils specifically identified from the “ Coralline” was somewhat meager. With the excep- tion of the corals, Spirifer crispus Hall was the only species described as identical with the Niagara fauna, and even that has been shown to be a variety.2, Besides one or two species of Stromatopora found in this reck and having but little value in correlation, the abundant Favosites was identified as F. niagarensis (?), while Halysites catenulatus? Linn., which at this time was not known above the Niagara, was considered the most important of the fossil forms in the correla- tion of the two rock masses. The many characteristic species of the Niagara however were absent, while the “ Coralline” was characterized by a peculiar gastropod and cephalopod fauna, a feature noticeably absent in the Niagara of western New York. These discrepancies between the two faunas were observed by * Palaeontology of New York. 1852. 2:321-38, pl. 72-78. *Grabau. Geol. Soc. Am. Bul. 11:352. * This fossil was known above the Niagara only in the sense that Hall regarded the overlying waterlime as Salina. Vanuxem had recorded this species from the base of the waterlime group and had given the position of the waterlime above the Onondaga salt group. This coral was identified by Van- uxem asCatenipora labyrinthica. Geol N.Y. 3d Dist. 4th An.

Happily, however, the “ Coralline” was described as a distinct formation. The position, in the rock series, given to the “ Coralline” at Schoharie appears to have been based chiefly on its relations to Pentarmecres Ua7estone Terracusire furvve store SaltgroupP the overlying and underlying beds which Hall regarded as the Salina and the Clinton re- spectively. With these deter- minations it was impossible to conclude that the “ Coralline” Fig. 1 Section at Sharon Springs, Schoharie was other than the Niagara. county (After Mather 1843) From its similarity to the Salina in western New York, the rock above the “Coralline” could be readily con- fused. But why the underlying shales, clearly resting on the Lorraine beds, were called Clinton was not explained. Mather! had already published a section at Sharon Springs, Schoharie co., where the Salina shales resting on the Lorraine beds and below the waterlime were designated as the Salt group, and Vanuxem? had shown the impossibility of any formation between the Salina and the Lorraine at the same place. He says: ‘“ The Onondaga salt group [Salina] and the Frankfort slate [Lorraine] are so near to each other, both being undisturbed, as to preclude every other deposit.” Though Hall states that the “Coralline” could be traced continuously from Herkimer county to Schoharie, it is very evident from the above citations as well as from his own published sections,’ that it could not be traced below the Salina, to which position it had been assigned.

And it is singular that here, where the Salina has a considerable thickness, the relations of these beds should not have been at least suggested. Vanuxem,! referring to the division line between the Salina and the Waterlime group in the eastern end of his district, repre- sented by Oneida, Herkimer and Otsego counties, says: ‘“ There a brownish impure limestone is seen, often mottled, containing columnariae of a somewhat spherical form and about the size of an inch or-more; also a few encrinital fragments, and a small orthocera, the species not named. This is the mass which sepa- rates the two groups, and forms the base of the Waterlime group.” Again? in speaking of the upper member of the Salt group, representing the Eurypterus-bearing bed of the Salina, he says: “Above the upper deposit there are irregular, light colored layers with globuliform columnaria and other fossils, which belong to the Waterlime group, or to an intermediate one which we do not attempt to establish.” It may seem at first sight that Vanuxem might have meant by the intermediate layer that portion which we term Rondout, holding a position between the “ Coralline ” below and the Manlius limestone above. It will be seen however that the Waterlime group as defined by Vanuxem consisted, in this part of the State, of three distinct divisions, included between the Eurypterus-bearing beds of the Salina below and the Coeymans limestone above. The divisions of the Waterlime group as given by Vanuxem are as follows®: “The first or lowest portion con- sists of irregular layers with globuliform columnaria; above which there is a drab colored series, followed by the upper blue or dark colored ones.” The section as above given agrees essentially with the one at Schoharie, the lowest member corresponding with the “ Coral- line,” the drab colored series with the Rondout and the uppermost blue or dark colored ones with the Manlius limestone.

Hall. Other fossils are mentioned as occurring in - the basal member, but they appear not to have been identified. Unfortunately, the studies of Vanuxem did not extend far east of Otsego county, and he did not cor- _ relate his sections in Otsego and Herkimer counties with those of Schoharie. It will thus be seen that, while Vanuxem recog- nized a section clearly above the Euryp- terus beds in Herkimer county, he did not realize that the lowest member of his Waterlime group was the continuation of the “ Coralline” of Schoharie county. On the other hand, Hall recognized the “ Coral- line” in both Schoharie and Herkimer counties, but in the latter he, evidently, was not aware of its position with refer- ence to the Eurypterus beds. The sections as above given, together with the results of a recent examination of the so called Clinton and Niagara forma- tions extending from Schoharie into Her- kimer county, clearly show that there is no representative of the Niagara east of Herkimer county; while the study of a new collection of fossils from Schoharie county and a similar examination of collections from horizons clearly above the Salina in western New York, conclusively demon- strate that the “Coralline” of Schoharie county is of an age later than the Salina, and that the “Coralline” has in New York State a greater extent than the Niagara itself. The inappropriateness of the term Niagara as applied to the “Coralline” has been recognized for some time by Dr Clarke. This, together with the incongruity of the word Coralline as a 1114 NEW YORK STATE MUSEUM stratigraphic unit, has led him to substitute for these unsatis- factory designations the name Cobleskill, as it is along this creek near Howes Cave that the outcrops of this limestone are most typical. i / Section at Howes Cave The accompanying section will serve to indicate the strati- graphic relations of the Cobleskill at Howes Cave. Directly beneath the Cobleskill the Salina shales are exposed with a thick- ness of 34 feet. The contact with the Lorraine beds can not be observed at this place, but in the bed of a small stream 1 mile farther north the contact is seen to be deceptively conformable. From observations made at this place, the thickness of the Salina at Howes Cave can not be far from 40 feet. The characters of these shales are quite uniform. In color they vary from a light eray to green. They break readily and soon crumple. The most conspicuous feature is the presence of nodular iron pyrites in such quantities that at Schoharie they were once mined. These shales have been quarried and sold for plaster, but, unlike beds of the Salina of western New York, they contain only traces of gypsum. Their value as a plaster seems to be due to the oxida- tion and decomposition of the iron pyrites, the sulfur of the pyrites combining with oxygen and water, forming sulfuric acid. The acid attacks the carbonate of lime present, forming lime sulfate, which, with the addition of two ‘parts of water, gives gypsum. Folding and slight displacements of these shales are often seen, specially near their lower portion. These, however, appear to be only local developments. There is no transition into the Cobles- kill. The line of demarcation is very strongly defined. The soft shales, weathering away beneath, sometimes leave the Cobles- kill as a projecting ledge. These same features are observed farther east at Schoharie, where the formation has a thickness of 27 feet, having thinned 18 feet in a distance of 5 miles. The most easterly extension of these shales that has been observed is near Gallupville, 5 miles east of Schoharie, showing that the extreme eastern extension of the great Salina beds of New York 1U.S.N. Y. Sec. Rep’t. Regents Bul. 59. 1902. p. r42. REPORT OF THE STATE PALEONTOLOGIST 1902 1115 can not be far from the town of Knox, Albany co., at which place it is quite likely that the Cobleskill slightly overlaps the Salina. Both of these formations are absent at Altamont a few miles far- ther east, and the Rondout is seen resting directly on the Lorraine beds. Rondout waterlimes Next above the Cobleskill is the Rondout waterlime, which at Howes Cave is 40 feet thick. The Rondout is transitional into the Manlius limestone above, as well as from the Cobleskill below. Hall? has called attention to the fact that, while in western New York, where the Manlius is absent, the line of demarcation be tween the Salina (=—Cobleskill or “ Bullhead” of Erie county) and the succeeding limestone (Onondaga) is very conspicuous, in eastern New York the Rondout, then regarded as the Salina, gradually gave way to conditions under which the Manlius lime- stone was formed. Regarding the “ Bullhead ” as Cobleskill, it will be seen that in New York, with the possible exception of Schoharie county, there appears to be no unconformity between the Salina and the overlying rock. The transition of the Rondout into the Manlius as observed in eastern New York is also to be noted at Cayuga lake, and these same conditions probably exist at least as far west as Seneca county, beyond which the Rondout and the Manlius have not been distinctly recognized. The transition from Cobleskill to Rondout is marked by a change from the limestone of the Cobleskill to the cement of the Rondout. The weathered surface of the upper portion of the Cobleskill varies slightly from the weathered Rondout, but fresh fracture clearly shows the distinctive character of the cement rock. The fauna of the lower Rondout, though much reduced in force, is distinctively a Cobleskill fauna. Hall found Haly- sites catenulatus in the Rondout of Herkimer county, and recently Prof. J. J. Stevenson? called attention to the fact that Favosites niagarensis Hall is found abundantly in the lower 3 feet of the Rondout (cement) at Howes Cave.

Ann. v. 13, no. 3, p. 365-66. 1116 NEW YORK STATE MUSEUM transition of the Rondout from the Cobleskill and the gradual passage into the Manlius were clearly recognized by Professor Stevenson, and, had he carried his observations a little farther. their true significance might have been realized. The gradual change from the Cobleskill, which he regarded as the Niagara, into the succeeding formations he explained by saying, “It is sufficiently evident that, while the great mass of Salina shales was in process of deposit in central New York and in much of the Appalachian region, the conditions within this portion of New York changed so gradually as to bring about only a slow disap- pearance of the fauna.” From similar observations, based on the section at Rondout N. Y., Messrs Ulrich and Schuchert! have correctly concluded that the so called * Clinton ” of Schoharie county is really Salina. There is no doubt, however, that they did not properly construe the section at Rondout in assuming that the ‘“ Coralline ” as there . developed is equivalent to the Cobleskill of the Schoharie section. It will be shown from the sections in Ulster county that, while the Cobleskill is present, the “ Coralline” of that region repre- sents an age earlier than the Cobleskill. It may be here stated that, while Hall wrongly concluded as to the age and position of the Cobleskill in Schoharie county, he was more nearly right in his estimation of the age of the “ Coralline” of Ulster county, though his conclusion in regard to the latter evidently was based on the Schoharie section. Fossil localities of the Cobleskill in Schoharie county The Cobleskill limestone is more or less fossiliferous through- out its extent in Schoharie county, and the following lists repre- sent the collections made from its various outcrops. The sections will be taken up in order, beginning with the most easterly and extending along the line of outcrop into the western part of the county. On the Stevens farm south of Shutter’s Corners and 3 miles east of Schoharie the Cobleskill is partly exposed for some dis- tance. This has proved to be the best collecting ground for 'N. Y.

At this place the three system cleavage has caused the upper part of the rock at several points to become hroken, so that the appearance is not unlike piles of pebbles. These pebbles often yield choice fossils of the smaller species, while the larger species are sometimes found in sections, being cut by the formation of cleavage planes. This method of weathering and in places the removal of the weathered material have left the harder portion, representing colonies of coral extending above the general sur- face of the rock. The appearance of these coral masses indicates that this was their original place of growth, and thus a locality favorable for the existence of other types of life illustrated by the fauna above given. That these coral beds were the habitat of many of these life forms is shown by the occurrence of Trochoceras gebhardi and large gastropods, resting on the summits of a coral growth. These gastropods, in turn, are seen to be places of attachment for new coral polyps, thus finally embedding the shells in the coral mass. Trochoceras geb- hardi is also found as the nucleus of large concretions, the surrounding mass of which is made up largely of coral growth. Below, in the more compact portion of the rock, there is a layer in which Chonetes jerseyensis Weller occurs in abundance. Associated with this species were found two fine specimens of Calymmene niagarensis Hall, the pygid- ium of Lichas (Dicranogmus) ptyonurus Hall, fragments of Homalonotus sp.; also a number of Proetus sp. and several specimens of the cosmopolitan brachiopod Atrypa reticularis Linn., which however is but rarely found in the Cobleskill. Fragments of a brachiopod which in general form REPORT OF THE STATE PALEONTOLOGIST 1902 1119 and surface markings strongly resembles Stropheodonta becki Hall have been found. They may however prove to be identical with S. textilis Hall.

One hundred yards south of Brown’s quarry, Mr E. Vroman has opened recently a quarry in the blue limestone strata repre sented by 2 and 3 of the above section. The rock has a ragged fracture and is so brittle that large blocks can be quarried only with difficulty. Between the two strata there are many some- what flattened forms of a large species of Favosites, much like F. helderbergiae Hall. They are generally incrusted in a covering of shaly material. When the upper layer is removed, the corals can be readily obtained. From the compact portion of the rock the following species were obtained. 1 Favosites niagarensis ?

An examination, however, of the above list will show that the species which are known to occur outside of the Cobles- kill limestone are largely Niagaran species. In this case, how- ever, these species are not indicative of the age of the Cobleskill, but must be looked on as the return of the Niagara and Guelph faunas after the long interval during which the Salina shales of central New York were deposited, and during which these faunas suffered such changes as time and environment would produce. A number of Cobleskill species continued their existence into the Rondout; and, so far as they have been observed, all the species that have been found near the base of the Rondout, with the exception of the Eurypterus, are forms also found in the Cobleskill, but none of the gastropods or cephalopods of the Cobleskill appear to pass upward into the Rondout. Cobleskill section at Union Springs, Cayuga lake The studies of Vanuxem extended as far west as Cayuga lake, the western limit of the third district. The last place where a line is sharply drawn between the Salina and the Waiterlime rec- ognized as consisting of three groups, is at Waterville, in Oneida county. From that place to Cayuga lake only one locality is mentioned where the brownish limestone, so characteristic of the base of his Waterlime group in the eastern end of the district, follows the Salina. This locality is near Jamesville, in Onondaga county. A number of quarries are mentioned about Cayuga lake, and a final disappearance of the group under the lake. The stratigraphic position of these quarries, however, is not clearly indicated. In this connection it is interesting to note that Hall in speaking of the fourth or upper deposit of the Salina group, says :! In Seneca county it does not appear in its usual characters; the highest rock of the group being a fine grained, dark colored, and grayish brown mass, which apparently represents the lower part Geol. N. Y. 4th Dist. 1843. p.129. 1130 NEW YORK STATE MUSEUM of this division. Between this and the succeeding limestone, there is an interval which is probably occupied by this mass, but too deeply covered to be visible. It appears on the east side of Cayuga lake, coming down to the shore. As will be shown later, the grayish brown mass represents the Cobleskill, the covered interval the Rondout and the succeeding limestone the Manlius. Attention was first prominently called to the section under con- sideration by the late Prof. S. G. Williams, in a Note on the Lower Helderberg Rocks of Cayuga Lake and in a paper on “The Western Extension of Rocks of Lower Helderberg Age in New York ”, published in the American Journal of Science.2 The sec- tion studied by Williams was in the vicinity of Union Springs and was included between the gypsum beds of the Salina and the Oriskany sandstone. From this section, having according to Williams a thickness of about 65 feet, he gives a list of 26 fossils, a number which were, according to the identifications, representa- tives of the Coeymans limestone and the New Scotland beds. It is evident, however, that Williams did not examine the upper horizons of this section that lie directly beneath the Oriskany sandstone, or he could hardly have failed to find a nearly typical Manlius limestone fauna and thus perhaps have reached a differ- ent conclusion as to the nature of the fauna about Union Springs. Though Williams in his determinations of the fossil forms seems to have been supported by such authorities as Hall and Whit- field, there can be no longer any doubt that the fauna was not © properly construed in assuming any definite biologic or strati- graphic relation to the Helderbergian series. The distinctively Siluric aspect of this fauna was first estab- lished by Dr Clarke,’ who has also given considerable attention to the stratigraphy about Union Springs, which has resulted in accurately determining the position in the rock series of the out- crops on Frontenac island, from which the fauna of this section is mainly obtained. The accompanying map showing the geo- logic relations about Union Springs has been prepared by Dr 16th An. Rep’t. N. Y. State Geologist. 1897. p.10-12. {811 *Ser.3. 1886. 31:139-45. *N.Y. State Mus.

The collections from the waterlimes of western New York by Mr Luther and notes bearing on the region examined, have been made available for my study and have given valuable suggestions in working out the relations of the Cobleskill. The study of the fauna from Frontenac island (Union Springs) and its com- parison with the fauna of the Cobleskill of Schoharie county have had a very important bearing in showing that the “ Coral- line” or Cobleskill of Schoharie county is of post-Salina age. That a probable relationship existed between these two rock masses had already been suggested by Dr Clarke. In speaking of the species associated with the Eurypterus in the Salina beds of Cayuga and Herkimer counties, he says:1 The study of these has indicated the probability that we may not be altogether secure in the time-honored interpretation and correlation of some of our other strata having similar lithologie characters, such for example as the Coralline limestone of Scho- harie county and the waterlimes of the eastward sections. The fauna of a specially interesting outcrop of dark dolomite appear- ing on Frontenac island in Cayuga lake, where it is intercalated between the Waterlime sirata, will, when fully studied, give important aid in the interpretation of the proper relations of these beds to those which they immediately precede in time and to which they are otherwise allied, that is to the true Helderbergian straia. The probability of a relation existing between the beds of Frontenac island and the Cobleskill of Schoharie county, as thus expressed, may now be considered a certainty. As already indi- cated, the result given by Dr Clarke, relative to the unmistakable _ Silurie aspect of the section at Union Springs, is confirmed by a reexamination of the fauna, of which the stratigraphic relations, as shown by the accompanying map, can leave no doubt as to the position of these rocks with reference to the true Helderbergian strata. ‘N.Y. State Paleontologist. An. Rep’t. 1902. p. 422. 11382 NEW YORK STATE MUSEUM Frontenac island The best location for the collection of Cobleskill fossils in the vicinity of Union Springs is on Frontenac island in Cayuga lake, about 14 mile from the village. This island, having an area of one half acre, is the remaining part of the south limb of an anti- cline, which has its axis extending in a direction a little north of east and passing through Hibiscus point, 34 of a mile north of the island. The upward flexure of the strata at Hibiscus point brings the gypsum beds above the lake level, but the dip on the north side of the anticline makes them again disappear below the lake at a point opposite the railroad junction. The surface of the island is nearly level and extends about 6 feet above the lake. The outcrops of the Cobleskill on the island consist of three _ strata of hard, dark magnesian limestone, having a dip to the south of about five hundred feet to the mile, thus bringing into view the three layers, which together have a thickness of 8 feet, 6 inches. The upper layer, which is soft and quite dark, has a thickness of 3 feet, 2 inches and breaks readily into small angular fragments. With the exception of corals it is the most fossilifer- ous layer. The middle layer which is 2 feet, 10 inches thick, con- tains Stromatopora in abundance and, except that the color is a little darker, it is precisely the same in appearance as the Stromatopora bed of the Manlius limestone, holding a position — 60 feet higher. The two upper layers are quite uniform in color, which is well retained even after they have been exposed for a considerable length of time. The lower layer, with a thickness of 2 feet, 6 inches, weathers a lighter color than the upper layers, is less fossiliferous and approaches more closely the character of the underlying Eurypterus beds. The Cobleskill limestone where exposed on the mainland is also fossiliferous, but no species were found that do not occur on the island. The following list therefore represents species identified from Frontenac island. 1 Chaetetes (Monotrypella) arbusculus Hall 2 Favosites niagarensis?

BORER re AS ac ne CR eee i oe x x The Cobleskill limestone appearing on Frontenac island also outcrops at the south end of Howland’s point, 14 mile northeast — of the island. The dip here is greater than on the island and the outcrop less favorable for collecting. The surface layers how- ever contain large white Favosites, making a strong contrast with the dark color of the limestone. The surface as here exposed is in places polished and grooved by glacial action, thus indicating its resistant nature. A short distance from this outcrop on the northwest end of Howland’s point there is an outcrop of the Salina waterlime carrying Eurypterus and an undescribed spe- cies of Lingula. This outcrop of the Salina shows that the beds of Cobleskill on Frontenac island immediately overlie the Euryp- terus beds of the Salina. The Cobleskill limestone is also exposed in O’Connor’s old quarry 114 miles northeast of the island. The section in this REPORT OF THE STATE PALEONTOLOGIST 1902 1135 quarry shows 6 feet of Salina waterlime, with 4 feet, 8 inches of Cobleskill. The Stromatopora layer forms the upper surface of the Cobleskill. The location of this quarry is about 85 feet above the lake, which shows that the average dip of the Cobleskill is about 120 feet a mile. It should be noticed however that in this region the dip varies greatly. This is due largely to the fact that the fiexures of the strata have been produced by two sources and at different times. One set of flexures evidently is produced by horizontal pressure resulting in a general tilting of the rocks, the other by vertical pressure from below producing local disturb- ances, sometimes locally counteracting the effect of the general tilting of the strata and sometimes producing low conical eleva- tions, showing that the pressure was applied at a single point. The pressure producing these local disturbances appears to be due to the increase in bulk of the underlying beds, in the form- ation of gypsum from its anhydrite. These beds of gypsum ap- pear to be forming at the present time and they offer other inter- esting features, which can not be considered here. Excellent examples of these local disturbances can be seen in the field just north of O’Connor’s quarry, where the Cobleskill is elevated into two cones, each having an elevation of 6 feet at the apex, where the rock is much broken and fissures are seen radiating from the center. A short distance northeast of O’Connor’s old quarry and at 15 to 20 feet higher there is another quarry in which 8 feet of Rondout waterlime is exposed. It will be seen from the position of these two quarries that the Cobleskill here holds the same posi- tion that it does in Schoharie county, namely, above the Salina and below the Rondout. The waterlime exposed in this quarry appears to be a good cement rock. It is dark in color, shows faint lines of deposition, and a tendency to split along these lines. A single segment of Eurypterus was found in the waterlime exposed in this quarry. The Cobleskill limestone again appears in the old quarry on the land of Mr John Wooley, about 34 of a mile south of Cross Roads. The part of the limestone which is exposed, is hard, dark 1136 NEW YORK STATE MUSEUM in color and has a thickness of 4 feet. The Stromatopora bed forms the upper surface. Below the Cobleskill there is exposed 12 to 15 feet of Salina waterlime, which becomes laminated and shaly on exposure. In the Salina a short distance below the Cobleskill, Lingula sp. undet. occurs. A cut on the Lehigh Valley Railroad, 14 of a mile east of Cross Roads station, passes through beds of gypsum at what is known as the Thompson quarry. Above the gypsum in the banks east of the pit, there are about 25 feet of Salina waterlime, overlain by the Cobleskill, which is here much folded and broken. The upper part of the Cobleskill is covered, but the overlying dark Rondout waterlime shows slightly in the top of the cut on the south side and in the field above. Near the middle of the Salina waterlime in this cut fossils are quite abundant. Several species of brachiopods and fragments of Eurypterus occur. The Lingula sp. undet. already mentioned as associated with the Eurypterus at Howland’s point, is found here extending to near the base of the waterlime. With the exception of a species of Leperditia, this Lingula appears to be the lowest fossil above the gypsum beds. The elevation of the Cobleskill in this cut is 510 feet A. T., which is 120 feet higher than Frontenac island. This outcrop in the cut however is on the other limb of the anticline, with a dip strongly toward the northwest, showing that the actual dip of the rocks is much greater than the above figures would seem to indicate. Manlius limestone at Union Springs The best exposure of the Manlius limestone in the vicinity of Union Springs is in the J. S. Shaliboo quarry, 1 mile south of the village. The part of the Manlius that is exposed is directly below the Oriskany sandstone. The upper layer of the Manlius is 4 feet 5 inches thick and quite free from Stromatopora, but Leperditia alta Hall and a small species of Tentaculites are very abundant. The next layer below is a fine, dark blue limestone containing much Stromatopora. This is the layer which in appearance is similar to the middle layer of the Coble- skill on Frontenac island, to which reference already has been REPORT OF THE STATE PALEONTOLOGIST 1902 1B made. The third layer contains less Stromatopora, while in the fourth layer it is absent. The lower layers weather nearly a uniform color. The following species have been identified from this quarry.

Tentaculites sp. m 0 bh & co OoOnN S Cobleskill in Seneca and Ontario counties In going west from Union Springs the same stratigraphic relations continue over the eastern-part of Seneca county, but in MeQuan’s quarry, 11% miles southwest of Seneca Falls, there is a bed of waterlime lying directly below the Oriskany sand- stone. This stratum of waterlime, which is 11 feet thick, con- tains Eurypterus within 2 feet of the Oriskany and represents ‘the Rondout. Below the Rondout there is a bed of dark blue limestone containing much Stromatopora in its upper part but much less near the base. This layer is 8 feet thick and much like the Cobleskill exposed on Frontenac island, to which form- ation it is referred. The Salina beds do not appear at this point, but at Seneca Falis the gypsum beds are overlain by Salina water- lime containing Eurypterus. The Stromatopora bed of the Cobleskill is covered at Seneca Falls, but it is evident from the position of these two sections that it is included between the Eurypterus bed of the Salina and the Rondout. Whether the Manlius limestone again appears west of Seneca Falls has not been satisfactorily established, though there are several localities where beds somewhat similar to the Manlius limestone have been observed. Hall! mentions but a single local- ity west of Cayuga lake, where fossils characteristic of the Man- ~1Geol. N. Y. 4th Dist. 1843. p.141—42. 1138 NEW YORK STATE MUSEUM lius limestone were found. This locality is in the town of Phelps, Ontario co. The thin layers in which the fossils occur are said to be directly above the Salina waterlime. The upper limit of the Salina as here given by Hall is not clear, since in Seneca county and at Union Springs the Cobleskill and the Rondout were included in the Salina. The fossils obtained by Hall from this locality were not well preserved, and the figures given are illustrations of typical Manlius limestone fossils from central New York and not of those that were obtained in Ontario county. Whatever the stratigraphic relations of these beds may be in the vicinity of Phelps, it is evident that, before the western limit . of the county is reached, there is found a stratum similar to the “ Bullhead ”, lying directly below the Oriskany or below the Onon- daga, where the Oriskany is lacking, and that it occurs in this position at a number of points between Ontario county and Buffalo, at which it is better known than at any other locality. Cobleskill, or ‘‘ Bullhead ” limestone, of Erie county The quarries of the Buffalo Cement Co. afford excellent expos- ures of the Cobleskill or “ Bullhead ” magnesian limestone. The Cobleskill lies directiy above the Eurypterus-bearing beds of the Salina and is transitional from them. According to a recent paper by Mr Schuchert! there is a hiatus between the Eurypterus- bearing beds of the Salina and the “ Bullhead” rock of Erie county. It is very evident however that the rocks between which the hiatus is said to occur are transitional, and that such a hiatus does not exist, nor would one have been considered by Mr Schu- chert had he correlated the “Bullhead” with the Cobleskill instead of with the Manlius. The upper surface of the Cobleskill at Buffalo is very irregu- lar, evidently because of elevation and erosion during the interval extending from Cobleskill and lasting till late Oriskany time. Another feature of the Cobleskill at Buffalo is the deep vertical fissures, extending through its entire thickness and well down into the cement beds of the Salina. Attention has already been ealled to similar fractures in the Cobleskill about Union Springs. 1U.S. Mus. Proc. 1902. 26:416. REPORT OF THE STATE PALEONTOLOGIST 1902 1139 Whether they were produced by similar causes, it is at present impossible to say. Grabau has expressed the opinion that those at Buffalo are probably due to an earthquake shock. Some of the fractures at Union Springs appear to be of recent origin, while those described from Buffalo must have been formed previ- Onordeqga L /mesfone. = ate if eee ey sl : | dy Po dipdoty. fit fd ¢ DN sf [SON a BEANE EPA DE LPC SALT PANT [tL ie Ey ty oh ee 4h ee Te sumain ST oe y vr / - > 7 rk uF 7 Sti i ; 1 pCobfeskill Limestove ZAP TTT j / f eee pes. / / / ey —$_— es is = 4 / AL Lf LIL TT TTT 40) fini }+—F =] ; =e a oe oe : oe f Pe (a, Se ZZ eo SPZZZ PZB LLLLEEILLILLLLE A EERE ee a OOo ee Fig. 3 Dike through Cobleskill limestone, Buffalo cement quarry (after Clarke) ous to Oriskany deposition, since they are filled with sand typical of the Oriskany. The dikes in the Cobleskill at Buffalo have been described in detail by both Dr Clarke! and Dr Grabau.? The stratum of Salina waterlime that is burned for “ hydraulic cement” at Buffalo is slightly more than 5 feet thick. It con- tains a number of species of Eurypterus and a species of Lingula, apparently the same that is associated with the Eurypterus at Union Springs. There are also a number of other species of fossils described from the cement bed. The character of the Cobleskill limestone varies considerably in its extent in New York State. In Schoharie county, where corals are so abundant that often they make up a large portion —— IN. Y. State Mus. Mem. 3. 1900. p.96-98. *Geol. Soc. Am. Bul. 1900. 11:357-61 1140 NEW YORK STATE MUSEUM of the rock, it is a limestone. In the western sections, where the corals common to the eastern portion are very rare, it is a dolo- mite. The petroleum odor so characteristic of the Cobleskill in Erie county is not observed in the eastern sections. In Erie county the rock is filled with cavities, due to the dissolving out of the corals, but in Schoharie county the corals often appear to be the most resistant portion of the rock. In both sections the Coble- skill is in some portions rich in iron pyrites. In the three sec- tions where the Cobleskill has been mainly studied it varies but little in thickness; at Buffalo it is 8 feet, 4 inches, at Union Springs 8 feet, 6 inches and in Schoharie county it averages 6 feet. In view of our present studies, the most interesting feature of the Cobleskill of Erie county is the fauna which it contains. Of this fauna a careful study has been made by Dr A. W.

Orthothetes interstriatus Hall, Spirifer eriensis Grabau, Trochoceras gebhardi Hall, Leperditia scalaris Jones. Two species, Cya- thophyllum hydraulicum Simpson and Whitfield- ella sulcata Van., occurring in the Cobleskill in Erie county, are also found in the Cobleskill at Union Springs. In the study of this fauna Dr Grabau obtained a good clue, which if followed would undoubtedly have enabled him to estab- lish the true position of the Cobleskill, or “ Coralline”, of Scho- harie county. Having followed however Hall’s correlation of the “ Coralline” as the eastern representative of the Niagara, he concluded “that the Manlius (= Cobleskill) limestone fauna of the Niagara region is a late return of the Coralline limestone fauna, at the close of the long interval during which the Salina shales were deposited in the Siluric seas of this region.” Cobleskill of the Hudson river valley In the opening sentence of the original description of the ‘‘ Cor- alline” limestone Hall! briefly refers to its occurrence in the Hudson river valley as follows: ‘In the neighborhood of Schoharie, and extending along the base of the Helderberg moun- tains and along the Hudson river, there is a thin mass of lime- stone, characterized by an immense number of corals, chiefly favosites, and which forms a band so distinct from any other limestone that it has been for many years known by this name.” Hall? makes another reference to the presence of this limestone in the Hudson river valley; he says ‘“ The Coralline limestone exists in place at several localities on the east side of the Held- erberg, but I have had no opportunity of examining these places in detail. It is not improbable that many more species may be added to those already known.” The fauna of this limestone in the Hudson river section how- ever remained unstudied. Darton has given us much relative to the occurrence of this limestone in Greene and Ulster counties, Dale and Davis have each made mention of its presence in the quarries about Rondout where it is typically developed, but, so ‘Palaeontology of New York. 1852. 2:321. * Palaeontology of New York. 1852. 2:337. 1142 NEW YORK STATE MUSEUM far as I am aware, it has always been considered the equivalent of the Cobleskill, or “Coralline”, limestone of Schoharie county.)

Y. In making this determination, however, these distinguished workers in paleontology followed Hall’s correlation of this “ Coralline” bed as the equivalent of the Cobleskill, or “ Coralline,” of Schoharie county, an obvious error now that it is known that in Ulster county the Cobleskill belongs to a higher horizon than the so called “ Coralline”, and consequently the “Coralline” of the Hudson river valley really belongs to an earlier age. Starting from the type locality of the Cobleskill in Schoharie county, where its stratigraphic relations to the overlying form- ations are accurately known, the Manlius limestone can be traced continuously across the Helderberg and into Ulster county. In a like manner, the Rondout at the base of the Manlius can be traced, but it is not always so conspicuous, and specially in the Helderberg it has become very thin, still in Albany county at Altamont, Indian Ladder, New Salem and South Bethlehem it ean be observed, and, since the Cobleskill and the Salina have thinned out, it rests directly on the Lorraine shales. Similar stratigraphic conditions exist in the vicinity of Catskill, Greene co., and southward from this place the Rondout becomes better developed, and good exposures are seen just north of West Camp in the cut of the West Shore Railroad. In Schoharie county the basal portion of the Rondout lying directly on the Cobleskill is burned for “ hydraulic ” cement, but in passing eastward over the Helderberg this cement bed thins out and is wanting for many miles. It comes in again before Ulster county is reached, and here, as in Schoharie county, it represents the basal portion of the Rondout as here defined. Throughout Ulster county this basal portion of the Rondout is 1144 NEW YORK STATE MUSEUM known as the “gray cement.” Directly beneath the Rondout, or “ gray cement,” the Cobleskill is found. The Cobleskill about the cement mines in Ulster county is known as the “ middle lime- stone ledge” and separates the Rondout, or “ gray cement,” from the underlying Salina waterlime locally known in Ulster county as the “black cement.” In the quarries and mines at Rondout the Cobleskill is repre- sented by a thin layer of limestone 7 inches thick. This layer, separating the Rondout from the Salina, weathers to a gray color and is characterized by Rhynchonella ?lamellata Hall and a species of Leperditia. Southwestward from Rondout the Cobleskill thickens rapidly and at Whiteport it is 10 feet, at Binnewater 12 feet and at Rosendale 15 feet. The Cobleskill also thickens northward from Rondout, and at East Kingston it is found to have a thickness of 10 feet. The Cobleskill was also observed near Glasco, where some specimens of Proetu's sp. undet. were collected. It also is seen in the vicinity of West Camp and northward toward Catskill. In .the Rosendale-Whiteport cement region Darton! has referred to the Cobleskill, or “middle .limestone ledge,” as follows: There are two cement beds in the Rosendale-Whiteport region, and at Rosendale the lower bed, or “‘ dark cement,” averages about 21 feet in thickness, and the upper bed, or *“ light cement,” 11 feet, with 14-15 feet of waterlimestones intervening. | In the cement region south of Whiteport there are two cement beds, the upper, or “ white cement,” having a thickness of 12 feet and the lower, or * gray (= black or dark) cement,” 18 feet with 17-20 feet of waterlime beds between them. The Cobleskill limestone in the Rosendale-Whiteport region con- tains an immense number of corals and other species character- istic of this formation in Schoharie county; but Darton did not give any account of its “ coralline ” character in this section. As will appear later, the Cobleskill in the vicinity of Rondout seems to have been included by Darton with the Manlius or Tentacu- lite limestone. The Salina waterlime, or * black cement,” is best developed at Rosendale, where it has a thickness of 22 feet, at Binnewater it 1N. Y. State Mus. 47th An. Rep’t. 1894. p. 528, 531. REPORT OF THE STATE PALEONTOLOGIST 1902 1145 is 15 feet and at Rondout 10 feet. It can also be seen at East Kingston, where it has a thickness of 10 feet. This bed can also be observed at Glasco and West Camp, at both of which it under- lies the Cobleskill. 7 Below the Salina waterlime, or “dark cement,” is found the “Coralline” of Hall and other authors. This limestone con- tains a fauna which is a mixture of Niagara and Cobleskill forms, and is indicative of the Salina age of this limestone. Over a portion of Ulster county this “Coralline” limestone occupies a position between what is usually considered the Clinton forma- tion! and the Salina waterlime. In this sense this “ Coralline ” limestone has the stratigraphic position of the Niagara, but, as the waterlime, in age, appears to represent only the upper portion of the Salina and is transitional from the limestone below, it ap- pears best to consider this “‘ Coralline” of Salina age. In this paper this limestone is designated as the Wilbur limestone, since it was near Wilbur in Ulster county that Mather? in 1843 gave us the following interesting section, of which the basal member is the Wilbur limestone.

N. Y. Ist Dist. 1843. p. 331. 1146 NEW YORK STATE MUSEUM From Rondout southwestward through Wilbur, the Wilbur limestone is exposed at a number of points and rests unconform- ably on the Lower Siluric (= Normanskill ?) shales. Still far- ther soutwestward along Rondout creek the Wilbur limestone is seen resting on the Clinton quartzite, but directly west, as at Whiteport and Binnewater, the Wilbur iimestone is lacking, and the cement bed rests directly on the Clinton quartzite. At High Falls there is a fossiliferous bed between the cement and the Clinton quartzite, and it is referred to the Wilbur limestone. At localities where the Wilbur limestone or the Salina water- lime rests on the Clinton quartzite, there is no marked evidence of any unconformity, though the hiatus between them must have been considerable if this quartzite is to be considered as Clinton. Passing north from Rondout, the Wilbur limestone is exposed in an old tramway which leads to the Becraft quarries. Darton! at this point gives the thickness of the Wilbur limestone as 5 inches. My examination of this section does not in all respects agree with Mr Darton’s. In describing the section above referred to, he says: The lower limestone members are exhibited lying on the Hud- son river slates in the railroad cut and some old cement openings near the turnpike. There is a 4 to 6 inch bed of impure, ferrugi- nous limestone containing Niagara corals. On this there lie 7 feet of dark gray limestones, impure near the base and for 2 feet toward the top. Two feet above their bottom is a fossiliferous layer containing Atrypa reticularis, a very unusual occurrence in this part of the formation. This limestone is over- laid by a 10 foot bed of cement rock, of which the upper 4 feet are of poor quality. Next above is a heavy mass of fine grained, dark colored, brecciated limestone, filled with a great variety of corals representing the Stromatopora layer of the Tentaculite (= Manlius) series. It has here the very remarkable thickness of 10 feet with only a few thin beds of typical Tentaculite mem- bers above. As the result of my examination of this section, I have con- cluded that the limestone beds containing Atrypa reticu- laris should be included with the Wilbur limestone, which 1N. Y. State Mus. 47th An, Rep’t. 1894. p.501. > N. Y. State Mus. 47th An. Rep’t 1894. p.511-12. REPORT OF THE STATE PALEONTOLOGIST 1902 1147 gives it about the same thickness that it has at Rondout. The 10 foot bed of cement rock above is the Salina waterlime, while the dark colored rock containing corals represents the Cobleskill. Regarding this “ Stromatopora layer ” as Manlius, it would allow but 10 feet between the Wilbur limestone and the Manlius or what amounts to the same, 10 feet for the combined thickness of the Salina waterlime, the Cobleskill limestone and the Rondout waterlime. The interpretation of this section as given by Darton seems to have had much to do with his ascribing certain features to the Manlius or “ Tentaculite” limestone which in reality do not - exist, and, since his paper is one that is often quoted, it may not be altogether out of place to call attention to this matter. In describing the Manlius limestone in Ulster county, Darton! says: “There is included at or near its base, notably in the quarries near Rondout, a dark gray, impure limestone containing many corals and representing the Stromatopora horizon.” This bed is un- questionably the Cobleskill, the real Stromatopora horizon being much higher. Its position is indicated in the section at Rondout. Again, in his description of the Manlius in Albany county, he says:? “Toward the base of the series there is usually a more massive bed containing Stromatopora, but the member is not con- spicuous in Albany county in its typical development.” It is very evident that Hall did not know what Darton meant by the Stromatopora bed above alluded to, for, following the last quota- tion, Hall adds as a correction the following footnote: This Stromatopora bed is excellently exposed on the Albany and Schoharie plank road beyond Altamont; also about 2 miles west of the road from Albany to Clarksville on the land of Mr - Merkel on the same road 2 miles northeast of Clarksville Most of these exposures show that the bed lies but a few feet ‘below the Pentamerus [—Coeymans] limestone. The Stromatopora bed as thus located by Hall was also noticed by Darton, but the locality is not given in his description; he Says: In the upper members there is a thin subbedding, indicated by a ribboning of alternating lighter and darker tints, constituting IN.

Just below this rib- boned series there is usually a thin bed of Stromatopora which characterizes this horizon. This is the true Stromatopora bed of the Manlius, and it ap- pears to characterize this limestone throughout its extent in New York and always in the position as above given. Northward from Kast Kingston the Wilbur limestone is mostly obscured. There is an exposure near Glasco, but from this point it is absent till West Camp is reached. where it is exposed in both limbs of a syncline which extends from West Camp to Catskill. The Wilbur limestone about West Camp is 8 feet thick, and out- side of its corals Leptaena rhomboidalis Wilck. is the abundant fossil Atrypa reticularis Linn. also occurs, but not so abundantly. The presence of the Wilbur beds far north of West Camp has not been established. There are corals at the base of the Rondout and on the Lower Siluric shales at Catskill, but they are considered as belonging to the Cobleskill. Results somewhat similar to those which I have obtained rela- tive to the stratigraphic relations of the cement beds at Rondout have been already expressed by the Hon. J. G. Lindsley! in a paper read before the Poughkeepsie Society of Natural Science in 1879. While the correlation of the cement beds at Rondout as given by Lindsley, differs essentially from that of the writer, it serves to show nevertheless that the cement beds at Rondout have before been considered as belonging to different ages, and this opinion is expressed by one who, as superintendent of the Newark Lime & Cement Co., was familiar with the section, and to whom the proper relations of the cement beds were of prime importance. The following quotation from the paper referred 10 above will clearly express the views held by Lindsley. In re ferring to quarries at Rondout, he says: In these quarries we find lying directly upon the slates, [—L. Siluric] two layers of coralline [Wilbur] limestone, the whole thickness of which varies from 6 feet to nearly 8 feet. This coralline iimestone is admitted by all geologists of the present time to belong to the Niagara epoch, being the small be- ginning of those rocks here at the east, which, increasing in thick- ness, assume such proportions in the western part of the State. | See Poughkeepsie Soe. Nat. Sci. Proc. 1879. p.44-48. REPORT OF THE STATE PALEONTOLOGIST 1902 1149 Let us now inquire if these are the only rocks at this place which belong to this epoch. We find lying between this coralline limestone and the tentacu- lite limestone of the Lower Helderberg some 40 feet of rock, of which most of the layers are used in the manufacture of cement, and this feature holds good for some distance to the north .and south of this point, but under quite different circumstances. At the Vlight Berg we have several courses or layers lying together, to the thickness of about 22 feet, all of which is used in the manufacture of cement, hitherto known as waterlime, and quite generally regarded as wholly belonging to the Waterlime group. The upper layers of this wateriime are of a light grayish drab in color, but those that lie directly upon the coralline limestone are nearly black. There is about the same thickness of each, and they are known by the quarrymen respectively as the light and dark cement. Now as we go either north or south, even no further than the Steep Rocks on the one hand, or Wilbur on the other, we find these light and dark cements separated; and between them is found another layer of limestone [= Cobleskill], so that instead of one thickness of cement rock of 22 feet, we have two of 12 or 15 feet each, the light colored lying above, and the dark below this intermediate layer. This last represents the general features and disposition of the rocks in nearly, if not quite all of the cement quarries in Ulster county, except those of the Vlight Berg. Dr S. T. Barrett, of Port Jervis, has made the rocks of the lower Helderberg and those immediately below them, in his vicinity, a special study for some time, and he is inclined to the opinion that our black cement rock and the over- lying coralline limestone, where that occurs, belong to the Niagara epoch, and I am led to the same view for the following reasons. The dark cement rock quite often presents a coralline structure, and the fossil molluscae and trilobites found embedded are such as seem to belong to the Niagara epoch. I have one of the latter which is nearly perfect, although it has been subjected to the burning process of the kilns. It answers every requisite of the Calymmene niagarensis, except as to size, it being somewhat larger than other specimens I have seen. The coral- line layers above the dark cement, where they prevail, have many specimens of Halysites, or chain coral, embedded in them, which Dr Hall says are not found above the Niagara. If this conclusion is correct regarding the proper classification of these rocks, we have existing at the Vlight Berg a state of stratification quite peculiar, in that the layers belonging to the Niagara epoch that are suitable for the manufacture of cement directly underlie the layers of the waterlime, so extensively used for the same purpose, and which so generally form the base of the Helderberg group. 1150 NEW YORK STATE MUSEUM The views as above expressed by Lindsley seem not to have been much in accord with those of contemporaneous writers, and, in fact, we are not altogether certain that Lindsley himself always retained the conclusions given in his paper. Dale, in a paper written at about the same time, refers to the upper Niagara beds of Lindsley in a manner which expresses doubt of their actual existence. Prof. W. M. Davis? in a later paper intended, in part at least, to serve as a supplement to the earlier ones of Lindsley and Dale, entirely ignores the section at Rondout as construed by Lindsley and gives 70 feet as the combined thickness of the water- lime (— Salina + Cobleskill + Rondout) and the Tentaculite (= Manlius) limestone. The Coralline (= Wilbur) limestone is given a thickness of 6 to 8 feet. This measurement as well as the preceding one is credited to Lindsley. Fauna of the Wilbur limestone The Wilbur limestone is fossiliferous wherever it has been examined. One of the best localities for the collection of its fossils is in the old mines at Rondout. The limestone contains fossils throughout its whole thickness, but collecting is best near the top, where the overlying cement has been removed for a time sufficient to allow the rock to weather. This requires but a com- paratively short period. The following species have been col- lected from the Wilbur limestone, and it is quite probable that the list will be increased when more extensive collections shall have been made at other localities. 1 Favosites cf. niagarensis Hall 2 Halysites catenulatus Linn. 3 Enterolasma caliculus Hall 4 Bryozoan sp. undet. 5 Atrypa reticularis Linn. 6 Camarotoechia neglecta Hall 7 Leptaena rhomboidalis Wilck. 8 Orthis hybrida Sow. 9 Orthothetes interstriatus Hall 10 Orbiculoidea cf. tenuilamellata Hall ' Am.

SNia bat oo { ALK xX An examination of the above faunal list shows at once that we have here an assemblage of species that strongly indicates that the Wilbur limestone is intermediate between the Niagara and the Cobleskill or, as already indicated, it is of Salina age. 1152 NEW YORK STATE MUSEUM In Ulster county there is a space above the Wilbur limestone represented by the lower cement bed that, with the exéeption of Leperditia, is almost nonfossiliferous, but, when the Cobleskill is reached, we have again, in part, the Wilbur limestone fauna, but with a less proportion of Niagara species and with an increase of new forms that have not been observed in any formation below the Cobleskill. In the 42 feet of shales and limestones below the Cobleskill of the Nearpass section in New Jersey there occurs a fauna which like that of the Wilbur limestone is Niagaran in charac- ter. In the latter section however the cement bed, so conspicuous below the Cobleskill, in Ulster county, is lacking, and the forma- tion is more or less fossiliferous throughout. Some of the layers in the New Jersey section are crowded with Leperditia strongly suggesting brackish water conditions, but to a much less extent than in Ulster county. The fauna of the Nearpass section has been studied with some detail by Weller,! and he was able to identify with more or less certainty 381 species that for the most part are well known Niagara species. Some of the identifications as thus made by Weller, presumably those of Niagara species, have been ques- tioned by Ulrich and Schuchert;? but, judging from the fact that we do have Niagara species below the Cobleskill in Ulster county and relying on the previous work of Weller, it would not be unsafe, I think, to assume that there is below the Cobleskill in the Nearpass section, as in Ulster county, a fauna with unmis- takable Niagara elements. One of the chief differences between the section in Ulster county and the Nearpass section is the development in the former of an extensive cement bed which is entirely lacking in the latter, but is represented by shales and limestones. In the Ulster county section the marine conditions during which the fauna of the Wilbur limestone flourished seem to have been followed by a period of nonmarine or brackish water conditions, during which the overlying cement bed was formed. This change in conditions of sedimentation caused an almost entire destruction of the fauna, 1N. J. State Geologist. An. Rep’t. 1899. p.7-20. *N. Y. State Paleontologist. An. Rep’t. 1901. p.650. REPORT OF THE STATE PALEONTOLOGIST 1902 1153 and in part accounts for the great abundance of fossils found at the top of the Wilbur limestone, where it grades into the cement rock above. In a like manner immense numbers of ostracods are found at the top of the cement at the juncture with the Cobleskill limestone. At the close of the Cobleskill there is an almost complete annihilation of the fauna. The nonmarine conditions of the Rondout were much more widespread in their influences than those during which the lower cement bed was formed, and throughout the extent of the Rondout in New York but few of the Cobleskill species pass upward into this formation. In some of the shaly layers at the top of the Cobleskill in Ulster county very many remains of trilobites and other fossils have been found, and somewhat similar conditions have been observed in Schoharie county. In the Nearpass section the conditions so affecting the faunas farther north are not so apparent, and the rock is of a more cal- careous nature throughout, and some of the species found in the lower part pass directly upward into the Cobleskill limestone. The age given to the formation below the Cobleskill in the Nearpass section as determined by Weller was the same as the Niagara. His determination, however, was made when the Cobleskill was supposed te represent the eastern extension of the Niagara. Still he showed that the Cobleskill can represent only the upper portion of the Niagara, and that it is transitional from the underlying limestone and shales. As we now know that the Cobleskill is just above the Salina, the fossiliferous formation just below the 6 foot bed of Cobleskill in the Nearpass section will be considered of Salina age. The Bossardville limestone lying below these fossiliferous beds in the Nearpass section, is also considered of Salina age. The Nearpass section as above construed, as well as the section in Ulster county, does not include any formation of Niagara age. The absence of the Niagara from these sections may in part be accounted for as follows. Beginning with Oneida sedimentation [fig. 4] we have each of the successive deposits overlapping the next older till the Niagara is reached. This series of overlaps is observed of the deposits in eastern New York laid down in the 1154 NEW YORK STATE MUSEUM SCHOHAAYVE et AIN6STON BECRAFT NEW SCOTLAND COEYMANS UNION SPRINGS YIELDERGEE RELA, —.

At the close of the Clinton there was a reelevation of the barrier, and the Niagara deposits do not overlap the Clinton formation and rest on the Lower Siluric shales, but in central New York the eastern ex- tension of the Niagara is found resting on the Clinton. The effect of this uplift on the limits of the Niagara deposits in the Cumberland basin is not so apparent, but none seem to have been deposited in New York. From late Niagara time subsidence again took place, and the Salina deposits of the Mississippian sea in New York spread east over the Niagara and Clinton formations, and the thinned edge rests on the Lower Siluric shales. A similar condition of over- lap is found in the deposits of the Salina age in the Cumberland basin. In the region of the Helderberg the Salina deposits of the Mississippian sea are separated from those of the Cumberland basin by quite an interval, but in southeastern New York, where the barrier was lower, they must have been very close together, and the last deposits may have mingled and a few Eurypterus passed from the Salina sea into the Cumberland basin. With the clearing of the water brought about by the subsidence of the barrier, the Salina stage was brought to a close, and we have the Atlantic waters spreading over the late Salina sea. The spreading of the Atlantic waters over this area brought with them an Atlantic fauna. This invasion is known as the Helder- bergian, or it may be properly designated the Cobleskill invasion, since it was during Cobleskill time that we have the first invasion of an Atlantic fauna into the interior following the Salina age. This invasion of the Atlantic waters explains in part the deriva- tion of the fauna of the Cobleskill limestone as found in Schoharie county. *N. Y. State Paleontologist. An.

An analysis of this element in the Cobleskill fauna shows that a number of the species are identical with Guelph species of New York and the West. Among these forms are found such Guelph species as Orthoceras trusitum Clarke & Ruedemann, Kionoceras darwini Billings and Ilionia galtensis Whiteaves and other species which appear in the foregoing lists. Species common to the Niagara and the Guelph and not observed in the Cobleskill of eastern New York occur in Schoharie county with the true Guelph species. There are also Niagara species in the Cobleskill found in the Niagara of the West, but which do not occur in the Niagara of New York. The presence of Guelph species in the Cobleskill is accounted for as follows. At the close of the Niagara age there was an increase in the salinity of the water, which was the first step toward bringing about the conditions of the Salina sea. During this period following the Niagara, the Guelph fauna of New York flourished, but finally retreated as the sea became more saline. Again at the close of the Salina age, when in western and central New York nearly normal marine conditions had been established, the Guelph fauna returned and met the invading fauna of the Atlantic. The mingling of these two faunas shows that during Cobleskill time the waters of the Atlantic and the Mississippian sea were in communication. In the conclusion which I have reached relative to the mingling of these waters I differ from Ulrich & Schuchert,' who state that, though the barrier to the east was crossed, a younger fold “still prevented the Atlantic from joining the Mississippian sea throughout the time from Medina well into the Oriskany.” IN. Y. State Paleontologist. An. Rep’t 1901. 1902. p.662. REPORT OF THE STATE PALEONTOLOGIST 1902 1157 Rondout formation The mingling of the Atlantic waters with those of the Missis- sippian sea was of but short duration, and the Cobleskill was brought to a close by the formation of a barrier in western New York. This barrier as it grew caused a retrogression of the suc- ceeding deposits lasting into Devonic time and effectually sepa- rated the waters of the Atlantic from the Mississippian sea till late Oriskany time, when some of the Oriskany sand was de- posited in the crevices forming dikes and on the eroded surface of the Cobleskill. With the elevation of the Cobleskill in western New York, the true marine conditions under which the Cobleskill fauna flour- ished were also brought to a close, and in New York there was again formed a lagoon or bay in which the Rondout sediments were deposited. This bay was similar in some respects to the early Salina sea, but was diametrically opposite in that it formed an arm of the Atlantic instead of the Mississippian sea. The - conditions following the close of the Cobleskill were such that but few of the Cobleskill species pass up into the Rondout. That the Rondout was, unlike the Cobleskill, a nonmarine formation is shown by the return of the Eurypterus fauna, though much reduced in force. At Seneca Falls Eurypterus have been found in the Rondout but 2 feet below the Oriskany sandstone. They have also been observed in several localities about Union Springs and eastward. The writer has found Eurypterus remipes, in place near Cherry Valley at a horizon which may possibly prove to be the Rondout; and, till the exact horizon is determined, this find is chiefly interesting in that it is the most eastern locality in New York from which Eurypterus has been obtained. In eastern New York and the Helderberg the conditions favor- able for the existence of Eurypterus seem to have been lacking, at least none have been found indicating that these localities were in more direct communication with the sea. The fauna found at the base of the Rondout in the Helderberg sections is made up of species which continued their existence from the Cobleskill, and which do not pass upward into the Manlius lime- stone. In central New York there is a relation between the 1158 NEW YORK STATE MUSEUM _faunas of the Rondout and the Manlius, and this relation is expressed chiefly by the passage of Eurypterus up into the Manlius limestone. Hall early called attention to the finding of “a specimen con- taining a part of the head of a Eurypterus and several impres- sions of a spirifer peculiar to the tentaculite limestone. The character of the rock is intermediate in color, texture and com- position, between the ordinary drab colored layers of the Onon- daga salt group, and those of the tentaculite limestone.” It is possible that the above specimen may have been obtained from the Rondout. Dr Clarke, however, has recently informed me that he has found EKurypterus in the blue layers of the Manlius limestone in Herkimer county. In Onondaga county, above the blue layers containing the typical Manlius limestone fauna there are two layers of ‘ Waterlime ” from which the original “ water- lime of Manlius” takes its name. From the upper layer of this waterlime Luther? obtained a segment of a Eurypterus, showing that these interesting creatures continued their existence through all of late Siluric time, and that in this section at least there was an alternation in the character of the sediments and, as sug- gested by the fauna found in them. a considerable variation in the degree of the purity of the waters in which the sediments were deposited. Culmination and decline of the Salina sea The occurrence of Guelph and Niagara species in the Cobleskill at the close of the Salina is very suggestive. The limits of the Salina deposits as now known are marked faunally by lower and upper Eurypterus beds, signifying that the period opened and closed under similar physical conditions. If, however, we start at the close of the Niagara period, we find the first indication of increasing salinity, and with this change came the Guelph® fauna.

The deposition of these great beds of rock salt marks the turning point in this cycle, at which time the Salina sea contained very little if any water at all. With the increasing depth of the sea, beds of gypsum were again deposited, but never again were the conditions favorable for the deposition of extensive beds of rock salt. Following the gypsum beds, we have the Salina waterlime with its splendid Eurypterus fauna, and associated with the Eurypterus is a species of Lingula similar to the one at the base of the Salina. Above the Eurypterus beds we have the Cobleskill limestone, and here again we have repre- sentatives of the Niagara-Guelph fauna. | Era or system | Period or group | Age or stage ( { Manlius limestone | Rondout waterlime Cobleskill limestone + Salina beds | Wilbur limestone, (Pittsford shale, local facies) { Guelph dolomite Niagaran Lockport limestone Cayugan (Neontaric) 1QOntaric or Siluric 4 (Mesontaric) Rochester shale Clinton beds Oswegan Medina sandstone (Paleontaric) Oneida conglomerate l Shawangunk grit Upper Siluric sections in Onondaga county The upper limit of the waterlime group of Vanuxem, in the eastern part of the third district was marked by the Coeymans limestone.

The middle portion is best shown at Brown’s falls on the west branch of Limestone creek, 114 miles southwest of the village of Manlius, while the upper portions are made accessible by the natural outcrops and the extensive quarries in the hill just east of Manlius. Section at the Heard gypsum quarry Salina formation. North from the quarry there is exposed in the road and in the fields a dark porous limestone. In some of the thinnest layers Leperditia ef. scalaris is very abundant, while a small species of Whitfieldella is very common in the other portions of the rock. This limestone was formerly burnt for lime and its horizon is about 40 feet below the gypsum exposed in the quarry. The interval between this outcrop and the base of the gypsum quarry does not show any outcrop of the limestone. The gypsum including numerous intercalations of shale, is 65 feet thick and is overlain by 10 feet of olive-green shales which are quite soft, and often they lose their regular structure and become complicated, due largely to dissolving out of gypsum and to changes which have taken place in the under- lying mass. Above these soft shales there are 6 feet of Salina waterlime. The appearance of the rock is similar to the Salina waterlime of Herkimer county. Fragments of Eurypterus are frequently seen but the Lingula found at the same horizon farther west has not been observed. A small quantity of Salina waterlime taken out in the process of quarrying gypsum is now burned for cement, but it has never formed an important factor in the cement industry of Onondaga county. Cobleskill limestone. The Cobleskill limestone directly suc- ceeds the Salina waterlime. In this section the basal portion for 4 feet possesses the usual features of the Cobleskill of the eastern sections and is characterized by such fossils as S piri- fer crispus var. corallinensis, Whitfieldella nucleolata, Chonetes jerseyensis and Stro- pheodonta bipartita. The upper portion is transitional into the Rondout waterlime, from which it is not readily distinguishable. 1162 NEW YORK STATE MUSEUM Rondout waterlime. Only the basal portion of the Rondout is Shown in this section. The rock here is brecciated and filled with cavities, some of which are quite large. Many of the smaller cavities are due to the dissolving out of the coral Cyathophyllum hydraulicum Simpson. In appear- ance this rock is similar to the “bullhead” rock of Erie county. The Rondout is burned to a small extent for cement, and then only when it is mixed with the cement rock of the upper horizons. | The section as above given agrees essentially with one near Jamesville, published by Vanuxem.1 Number 5 of his section is the Salina waterlime and according to his statement this was the only locality in the third district south of the Erie canal where cement was made from the rock of these lower horizons [p.110]. Number 6 includes what is now recognized as the Cobleskill limestone and the lower portion of the Rondout waterlime. The cyathophyllum mentioned by Vanuxem [p. 110] is unquestionably the one that is now identified as Cyatho- phyllum hydraulicum Simpson. The section given by Vanuxem is described under the third or gypseous deposit of the Onondaga salt group and is important in showing that in the type locality of the original waterlime group in Onondaga county not only Salina waterlime, but also the formations now known as the Cobleskill limestone and the Rondout waterlime, were included in the Onondaga salt group and not in the Water- lime group as has been generally supposed. Section at Brown’s falls Cobleskill limestone. On the west branch of Limestone creek 114 miles southwest from Manlius village the Cobleskill lime- stone is exposed in the bed and banks of the creek 200 yards below the foot of the falls. The Cobleskill is here a compact limestone. The strata below the Cobleskill are only obscurely shown. Rondout waterlime. The basal portion of the Rondout is filled with cavities, and is similar to the lower portion as seen in 1 Geol. N. Y. 3d Dist. 1842. p. 105.

The total thickness of the Rondout as determined at this section is 45 feet. Manlius formation. The lower portion of the Manlius is similar in appearance to the upper portion of the Rondout and gradually changes to the characteristic blue layers. The blue layers carry the typical Manlius fauna. In some of the layers fossils are exceedingly abundant, while in others they are rare. Some slabs contain an immense number of Spirifer vanuxemi and others contain equally large numbers of Leperditia alta. Tentaculites gyracanthus, so plentiful in the Helderberg section, is not found abundantly at Manlius. The Stromatopora bed of the Manlius occurs at the top of these blue layers just below the lower cement bed. In the eastern sections the Stromatopora bed is near the top of the Manlius not far below the Coeymans limestone. The thickness of the Manlius limestone up to the cement bed is 65 feet. The cement bed which follows the Stromatopora bed is 4 feet thick. No fossils have been observed in this layer. Above this cement bed is a layer of blue limestone 4 feet thick. Spirifer vanuxemi and Leperditia alta were obtained from this bed. The limestone is followed by another layer of cemeut 4 feet thick. Mr Luther records the finding of a segment of a Eurypterus from this upper cement bed in the quarry at Split Rock, south from Syracuse. The section above the cement beds can be observed in this vicinity but not so advantageously as in the hill east of Manlius. Section in the hill east of Manlius village The lower part of the Manlius limestone is not well exposed. It can be seen however at the cut of the Chenango branch of the West Shore Railroad northwest from the station. In, this cut there is a brecciated layer of limestone 1 foot thick. The rock in this cut and in the outcrops in the fields above is very fossili- ferous. The two layers of cement are well exposed in this hill where they are extensively quarried for cement. Above the upper cement bed there is an irregular layer of limestone 14 feet thick. In lithologic features it closely resembles the 1164 NEW YORK STATE MUSEUM Manlius. It is but sparingly fossiliferous and appears: to be transitional into the Helderbergian to which formation it is provisionally referred. This blue limestone layer is followed by the Stromatopora bed 12 feet thick. The upper portion is very much broken by the formation of deep vertical fissures, similar to those seen in the Coeymans limestone. This Stroma- topora layer is referred to by Vanuxem |[loc. cit. p. 110] where — he says: ‘ One of the layers, usually from four to five feet in thickness, is traversed by oblique cracks in at least three direc- tions, breaking the mass into irregular parts or fragments; this layer is very fine grained.” Besides Stromatopora found in this layer, corals of the genus Favosites are quite abundant. Spirifer cyclopterus is also frequently found. | The Stromatopora bed is followed by 14 feet of massive blue limestone locally known as the “upper blue beds.” Fossils other than Leperditia are rare in these beds. Following these “upper blue beds” and directly below the Oriskany sandstone there is a massive gray limestone 6 feet thick in which some species of fossils are very abundant. This gray limestone ap- pears not to be present at all localities and where absent the Oriskany sandstone follows directly the “upper blue beds.” The following species were obtained within 8 feet of the Oris- kany sandstone. 1 Leptaena rhomboidalis Wilckens 2 Orbiculoidea cf. discus Hall 3 Spirifer cyclopterus Hall 4 Stropheodonta becki Hall 5 Trematospira formosa Hall 6 Meristella cf. laevis Vanuxem 7 Conocardium sp. undet. 8 Pterinea communis Hall 9 Tentaculites elongatus Hall 10 Leperditia sp. undet.

As I have had recently an opportunity to examine the section about Litchfield, Herkimer co. it seems to me best to note in what respects we have differed in our sections and hence why we differ so widely in cur results, specially in regard to the grouping of the rocks under consideration, a differ- ence which to a large degree would have been avoided, were we more in accord in our stratigraphic and faunal determinations. ied American Geologist. March 1903. p.160-78. 1166 NEW YORK STATE MUSEUM Section near Port Jervis (Nearpass quarry section) For reasons which are more fully stated hereafter Mr Schu- chert proposed to include under the group term Manlius, the Manlius or Tentaculite limestone, the Rondout waterlime and the Cobleskill limestone as developed in the counties of Schoharie and Herkimer. In the section about Port Jervis it is very evi- dent that these limits have been greatly exceeded and that he has included with the Manlius, strata which contain a fauna that is unquestionably older than the fauna of the Cobleskill as devel- oped in its typical sections. Below the Cobleskill in the Near- pass section there are 42 feet of shales and limestones. ‘“ The diagnostic fossil of the lower half is Chonetes jerseyen- sis, otherwise the fauna is that of the Cobleskill member minus its corals” [p. 174]. It will thus be seen that not a single Niagaran species is recognized in this section since according to Mr Schuchert the Cobleskill contains no Niagaran species. This however is not in agreement with determinations made by Bar- rett, Weller and Whitfield, who have recognized Niagaran species therein. The Bossardville limestone at the base of the formation is correlated by Mr Schuchert with the Salina. Section at Rondout The Rondout formation as originally defined was intended to apply to the upper beds of the Salina characterized by an abund- ance of Eurypterus. Since it has been shown that at the type locality of the Rondout, the Wilbur limestone (= Coralline of Hall) is not the equivalent of the Cobleskill but belongs to an earlier age and stratigraphically lies below the cement bed of the Salina as well as below the Cobleskill, it follows that in its type locality the Rondout beds originally included the stratigraphic equivalent of the Eurypterus bearing waterlime of the Salina, the Cobleskill limestone and the Rondout waterlime as now restricted to that portion lying above the Cobleskill limestone. The re stricted sense in which I have used the term Rondout may be the same as the intended use of this term by Mr Schuchert, but in the Rondout section he has failed to recognize the true Cobleskill, and hence his application of the term Rondout here is with its . original limits and includes beds of Salina age, while in the other REPORT OF THE STATE PALEONTOLOGIST 1902 1167 sections cited by him it is restricted to the waterlime above the Cobleskill limestone. For the upper Eurypterus-bearing beds of the Salina Mr Schuchert uses the term Bertie formation which was introduced by Chapman in 1864. This formation strati- graphically is equivalent to the basal portion of the original Rondout. Herkimer county section In the town of Litchfield the upper Eurypterus beds of the Salina are exposed on the farm of Prof. C. F. Wheelock. Near the outcrop of the Eurypterus beds, Wheelock’s creek has its origin. This creek flows north and joins Moyer creek near the point where the Oneida conglomerate outcrops. It is along Wheelock’s creek that the following section was observed. Oneida conglomerate. Basal member very coarse, resting on the Lorraine. After 5 feet of conglomerate there is an alterna- tion of sandstone and conglomerate which finally grades into the Medina. The pebbles are found quite abundantly for 45 feet. Medina sandstone. Above the conglomerate are about 70 feet of Medina sandstone. In his section Schuchert states that the Medina is absent. Likewise Vanuxem! and Hall? both state that the Medina is not found east of Oneida county. It should be observed, however, that Hall’s statement appears to have been based on the report of Vanuxem and the latter always considered the Clinton as directly following the Oneida while the Medina was described as below the Oneida. A single quotation from Vanuxem’s report [p. 75] will serve to show that he regarded the Oneida as part of the Clinton. He says “ The conglomerate forms a part of the Clinton group, the next mass in order of super- position.” | Clinton formation. The Clinton shales and sandstones are well exposed and have a thickness not far from 150 feet.

In his section Mr Schuchert states that the Niagara is absent and that “ Hall was able to find the Niagara formation as far east as Oneida county” [p. 162]. Vanuxem! records the pres- ence of the Niagara in Steeles creek, Herkimer county. This out- crop is about 8 miles southeast from the section under consider- ation, and its presence there is also recorded by Hall. The Ni- agara can be observed in place there on the right of the highway passing from Ilion to Cedarville. This exposure affords a favor- able opportunity to study the concretionary nature of the Niagara and its contact with the Salina shales. The Niagara has not been observed east of Steeles creek. There are some sections in western Herkimer and eastern Oneida where the Niagara is covered. Hall* states: ‘ Over a part of Oneida county and the western part of Herkimer, there is a space where no rep- resentative of the Niagara group has been traced continuously ; not that the place where it should occur has been examined and found to be wanting, but because there are no good exposures of the strata which enable one to examine and determine satis- factorily the presence or absence of a thin bed like this one. In tracing the same line eastward however, into Herkimer county, there is a thin mass of limestone holding the same place, but more closely united perhaps with the drab limestone above, which is the thinned Onondaga-salt group.” The thin mass of limestone referred to is the Cobleskill. Tracing the Niagara from Oneida county eastward should have brought Hall to the expos- ure of the Niagara on Steeles creek, but at a point west of Steeles creek, he records the presence of the Coralline thus showing that the position of the Cobleskill as given by Hall was due to some extent to an error in correlation in Herkimer county. In Wheelock’s creek the Niagara is thin, but the contact with the Clinton and the Salina can be favorably seen in the bed of the stream. The geodic concretions containing dolomite crystals, 1Geol.N.

At this particular locality the base of the Niagara is a very dark shale, possibly the eastern extension of the Rochester shale. Salina beds. The red shales of the Salina are excellently ex- posed along the creek bed and highway which crosses the creek below Wheelock’s farm. A considerable portion of the upper Salina is not shown, but the Eurvpterus waterlimes are exposed on the Wheelock farm. The total thickness of the Salina can not be much less than 500 feet. Cobleskill limestone. The best exposures of this limestone in the vicinity of the Wheelock farm is on the Augar and Morris farms, and in the highway 15 mile east of Wheeleck’s. It is also exposed 2 miles east, not far from Steeles creek on the Kolb farm. There are other outcrops of the Cobleskill southeast from Wheelock’s near the Palmer cheese factory. Near the latter place the Eurypterus beds are shown in the highway and the Cobleskill outcrops just above, and for a mile frequent expos- ures are seen near the highway leading to Cedarville. The thickness of the Cobleskill in Herkimer county is given by Mr Schuchert as 30 feet, but I have not been able to find any outcrops where the thickness was so great. Hall states that in Herkimer county it is “ only a few feet thick ” and observations made about the Kolb farm show a thickness of about 10 feet, though there are places where through the action of the “ creep- ing ” movement of the detached edge of the outcrop the thickness appears to be greater. The contact of the Cobleskill with the Rondout was advantageously observed at only one point. At the top of the Cobleskill Leperditia scalaris Jones and a large species of Beyrichia were found quite abundantly. Rondout and the Manlius formations. The combined thickness of the Rondout and the Manlius is about 100 feet. The Rondout is of a sandy hydraulic nature with but few fossils. In the thin sandy layers Eurypterus are occasionally found. On one slab from the Rondout with Eurypterus there is found Rhyn- chonella? lamellata Halland Whitfieldella Sp. The Manlius contains its usual fauna and in this section it is also characterized by many beautiful crinoids. The upper portion of 1170 NEW YORK STATE MUSEUM the Manlius becomes complicated with the Coeymans limestone, the faunas of these two formations either mingling or alternately recurring. Age of the shales below the Cobleskill at Schoharie The shales below the Cobleskill at Schoharie were desig- nated as Clinton by Hall and now that we know that the Coble- skill is above the Salina the age of these unfossiliferous shales again comes into question. Mr Schuchert [p. 173] holds that “on the basis of the adjoining sections, the age of these olive green shales seems to be Lower Cobleskill.” What appears to be the chief argument, given for the determination of the age of the shales as Lower Cobleskill is as follows [p. 176]. “In Herkimer county the Clinton is not followed by the Niagaran, but at once by the Salina. Farther east the Clinton also fails, and at Schoharie, after 19 feet of the pyritiferous shales, there follow at once the Cobleskill, the Rondout, with the Coralline fauna, the Upper Manlius, and then the Helderbergian. Here the united thickness of the Cobleskill, Rondout and Upper Manlius is 91 feet, while about Litchfield the same zones are 110 feet thick. Therefore, the pyritiferous shale of Schoharie can not be the Clinton, but probably is the thinned eastern edge of the lower part of the Cobleskill of the Litchfield section and not of the true Waterlime or Bertie formation.” Even if we grant the thickness of the Cobleskill in Herkimer county as 30 feet, Iam | unable to see how the shales at Schoharie can be the thinned eastern edge of the lower part of the Cobleskill. If 19 feet represented the total thickness of the shales at Schoharie, this if added to the Manlius group of Schuchert would give about the same thickness as in Herkimer county. But as a matter of fact the shales below the Cobleskill at Schoharie have a greater thickness than that given to the Cobleskill in Herkimer county. The shales therefore can not represent the thinned eastern ex- tension of the Cobleskill. Again in Schoharie county at Howes Cave the thickness of these shales is about 40 feet, which if added to the Manlius would give in Schoharie county a much greater thickness than the Manlius of Herkimer county as defined by Schuchert, thus showing more conclusively that the ee REPORT OF THE STATE PALEONTOLOGIST 1902 1171 shales of the Schoharie section are not the thinned edge of the Cobleskill of Herkimer county. I am of the opinion that the pyritiferous shales of the Schoharie section can not be of an age later than the Eurypterus beds of the Salina. In western New York we have the Cobleskill following directly the Eurypterus beds. The transition from the one to the other has previously been noted. Specimens of Eurypterus from the Salina water- lime of Erie county have associated with them Orthothetes interstriatus and Leperditia scalaris, two fos- sils common to the Cobleskill from Schoharie county westward. At Union Springs somewhat similar conditions exist, while in Herkimer county the Eurypterus beds are also in close proxim- ity to the Cobleskill. These observations together with an examination of the section at Sharon Springs makes it difficult to conceive how the shales of the Schoharie section can be other than the Salina. The formational term Manlius The term “ Waterlime group of Manlius” was introduced by Vanuxem! and takes its name? from the two layers of water- lime lying above the horizon of the blue limestones containing the typical Manlius limestone fauna. That is we have in New York State three distinct waterlime horizons, (1) the Salina waterlime below the Cobleskill, (2) the Rondout waterlime above the Cobleskill and (8) the Manlius waterlimes above the horizon containing what is now recognized as the Manlius limestone fauna. These upper layers of waterlime are of a somewhat local development, a fact that was not clearly brought out by Vanuxem and thus has arisen much confusion relative to the position of the several cement horizons and they have generally been treated without much regard to their stratigraphic rela- tions. It should then be observed that included in the upper portion of the original Manlius is a waterlime and that the group was made to include all the waterlimes of the vicinity having a commercial value and not founded on any exact or even ap- proximate stratigraphic or paleontologic determinations. It *3d Annual Report. 1839. p. 272. *Geol. N. Y. 3d Dist. p.110. N.Y. State Geologist. 15th An. Report. 1898. p. 267. 1172 NEW YORK STATE MUSEUM will thus be seen how the Manlius or Tentaculite limestone with its distinctive fauna came to be included with the waterlime group. In the final report of the third district Vanuxem! does not use the term Waterlime group of Manlius but simply Waterlime group. ‘The fauna cited by Vanuxem is that of the Tentaculite limestone of Gebhard and Mather. In 1899 when it became de- sirable to substitute for Tentaculite limestone a locality name, Manlius was the term chosen, and as defined by Clarke & Schuchert? it is the equivalent of the ‘“ Tentaculite limestone of Gebhard, Mather and later writers.” Since it has been shown that at the type locality of the Manlius the Cobleskill was included with the Salina it is in the latter sense that I have used the term Manlius throughout and always as a unit, though I have realized that the original waterlime group in the eastern portion of the district provisionally included the Cobleskill. Vanuxem® there referred what is now recognized as the Cobies- kill to the waterlime group or to an intermediate one which he did not attempt to define. The Manlius waterlime was never strictly defined and Hall’ regarded it as a superior mass and above the strata containing the typical fauna. Consequently in the eastern portion of the fourth district the Onondaga salt group included all the strata up to the Manlius limestone. The Salina group as thus construed by Hall in this portion of the State may have had much to do with his calling the waterlime above the Cobleskill in Schoharie county Salina, since it occupies the same position stratigraphically with reference to the Manlius limestone. Among the chief reasons advanced by Mr Schuchert for in- cluding the Cobleskill with the Manlius formation is the state- ment that the fauna of the Cobleskill does not contain a single Niagaran species, while it does contain a few species in common with the Manlius. I agree fully with Mr Schuchert that the Cobleskill and the Manlius contain species in common and I have 1 Geol Ni YY) 3d Dist. 1842)" priv: * Science, Dec. 15, 1899. *Geol. N.

REPORT OF THE STATE PALEONTOLOGIST 1902 1172 shown more species in common to the two formations than has he, but I do not agree with him that the Cobleskill is without Niagaran elements. The evidence I have presented indicates that the Cobleskill fauna is the last return of Guelph and Niagara species, and with the close of the Cobleskill the last Niagaran species disappears. The presence of these important Niagaran elements justifies one in keeping the Cobleskill formation distinct from the Manlius limestone. The use of the term Manlius in the broad sense proposed by Mr Schuchert involves the duplication of terms!, a feature which should be reluctantly accepted even if the stratigraphic and paleontologic interpretations could be considered correct. Additional note The fauna of the Cobleskill limestone of New Jersey, together with that of the underlying shales and limestones which are considered of Salina age has recently been described and illus- trated by Weller.2. The formations studied lie between the Rondout formation and the Bossardville limestone and are de- scribed under the name Decker Ferry formation, which Weller believes is the southern extension of what is now recognized as the Cobleskill limestone of Ulster county. This formation is best exposed in the Nearpass quarry hear Port Jervis. The number of species identified from this formation is 48. Six of the species previously known were described from the “Coralline” of Schoharie county by Hall, one Chonetes jerseyensis is found in the Cobleskill in Schoharie, Herki- mer, Onondaga counties and at Cayuga lake. The species now recognized as Proetus pachydermatus Barrett has been obtained from the Cobleskill in Schoharie and Ulster counties. Eight of the species, Favosites pyriformis Hall, Halysites catenulatus Linn, Atrypa retic- ularis Linn, Leptaena rhomboidalis Wilck., Orthisflabellites Foerste,Reticularia bicostata Van., Pterinea emacerdata Con. and Pterinea sub- plana Hall, are known from the Niagara of the interior but * Science, Dec. 15, 1899. p. 975. *Geol.

Two species are identified as Helderbergian forms—Pholidops ovata Hall and Rhynchospira formosa Hall. Among the ‘Species described as new Favosites corrugatus ap- _ pears to be the same as F. niagarensis ? Hall (—F. hel- derbergiae var. praecedens Schuchert), a coral found abundantly in the Cobleskill. Another species Rhynchon- ella agglomerata is the same as Rhynchonella? litehfieldensis Schuchert. Both authors note a similarity of the latter species to the Niagaran form Camarotoechia neglecta Hall, to which species it was referred by the writer. Of the other forms described Cladopora recti- lineata Simpson, Monotrypa corrugata Weller, and Wilsonia globosa Weller are found in the Wilbur limestone. A study of the Leperditia of the Ulster county sec- tion will undoubtedly show that it has a number of species in common with the Decker Ferry formation. The evidence furnished by the study of the Decker Ferry fauna shows that only the upper beds may be definitely correlated with the Cobleskill limestone. Though Weller states that [loc. cit. p.18] “the Decker Ferry formation, as well as the sub- jacent beds down to the Medina formation, were probably con- temporaneous with some portion or the whole of the Niagaran formations of the interior,” it can not longer be so considered since it has been shown that in the section along Wheelock’s creek in Herkimer county the original “ coralline” limestone is separated from the Niagara by the Salina, the latter having a thickness of more than 400 feet. It is evident that whatever elements we find in the fauna of the Decker Ferry formation, which are suggestive of Niagaran age, they must be looked on as a late return of Niagaran species. The fact that the Decker Ferry formation was, in part, deposited in a basin distinct from that in the interior accounts for variations in the faunas of the stratigraphically equivalent beds in central New York. Schuchert! includes all of the Decker Ferry formations under the term Manlius and Weller states that the Cobleskill at Ron- * Am. Geol. Mar. 1903. p. 174. REPORT OF THE STATE PALEONTOLOGIST 1902 1175 dout is believed to represent the extension of the Decker Ferry formation, in which case the lower cement bed at Rondout may be correlated with the Bossardville limestone. It is clear how- ever that the Bossardville limestone can not be correlated with the lower cement bed at Rondout since below the latter formation we have the Wilbur limestone with a fauna similar to the lower Decker Ferry fauna, which unites it with that formation and therefore the lower cement bed included between the Wilbur limestone and the Cobleskill limestone must be regarded as the stratigraphic equivalent of a portion of the Decker Ferry forma- tion. The presence of Leperditia and other fossils in the Bos- sardvilie limestone which lies just below the Decker Ferry forma- tion is indicative of the Salina age of this formation. In Ulster county the Bossardville limestone can not be recognized, but holding a similar stratigraphic position there is a series of soft greenish shales and quartzites which are usually referred to the Clinton formation, but which, together with the underlying red shales, as has been already suggested, may more properly be referred to the Salina. DISTURBED FOSSILIFEROUS ROCKS IN THE VICINITY OF RONDOUT N. Y. BY GILBERT VAN INGEN AND P. EDWIN CLARK With 13 plates The present paper describes briefiy some of the more import- ant stratigraphic and tectonic features observed by the authors during several years work in the vicinity of the cement mines at Rondout N. Y. It is a statement of progress of investiga- tions now being carried on and is submitted with the object of bringing to the attention of geologists the highly interesting fea- tures of that region. Several writers have published short papers on the region, but these have evidently been based on far too hasty examina- tion, with the result that, while the more evident features have been described, numerous far more interesting though often less easily recognized phenomena have escaped attention, and the paleontology has been entirely neglected. The particular district described embraces the hill called the Vlightberg in the city of Rondout, on which are located the quarries and mines of the Newark Lime & Cemeni Co., and also that wooded range of hills, referred to in this paper as the North hill fronting the Hudson river and extending from the Vlightberg northward to the Terry triangulation station of the United States Geological Survey situated on the hill west of Terry’s brickyard, about 1 mile north of Kingston Point. This area, about 1144 miles long by 14 mile wide, has been the scene of quarrying operations during the past 60 years, and the open- ings, which in the Vlightberg are common along the eastern por- tion of the hill, afford unusual opportunities for observation of the interesting and complex tectonic phenomena in which the region abounds. Folds, faults and overthrusts can be seen in almost diagrammatic clearness. Up to the present time almost nothing has been done toward description of the fossil faunas of Ulster county, and as the Rondout region affords excellent opportunities for collecting fossils from the various members of the Siluric and Lower Devonic formations, a considerable Plate 1 SOS F7 ‘O> .

Pal Li Location map showin REPORT OF THE STATE PALEONTOLOGIST 1902 1107 amount of material has been gathered by the senior author and the species have been identified to furnish the faunal lists accompanying this paper. One of the striking results of this paleontologic work is the discovery that a large number of those species heretofore considered to have been characteristic index fossils of the various members of the Helderbergian group are not confined to particular stages but range er two or more members of the series. The senior author, Mr van Ingen, first became acquainted with the region in 1888, and has visited it frequently since that date. The junior author, Mr Clark, has been superintendent of inining operations for the Newark Lime & Cement Co., for several years, and in that capacity has had fine opportunities to study the folding and faulting of the formations beneath the surface. In many cases the underground observations, supplementing the surface work, have enabled the authors to satisfactorily explain difficult points which could not have been solved by observations on the surface alone. The structure is in places so complicated by excessive folding and faulting that it has been found necessary to prepare a large scale map. This map, still in manuscript, with a scale of 100 feet to 1 inch is based on stadia survey with the stations gener- ally less than 100 feet apart, and all outcrops are tied up to sta- tions. In this way the construction of parallel cross sections at frequent intervals will be facilitated, and reproduction of the tectonic features of the region by a series of models will be made possible. While both authors have been closely associated in the study of the structural features, Mr van Ingen alone is responsible for the paleontologic portion. The authors wish to acknowledge their indebtedness to Mr Calvin Tomkins, president of the New- ark Lime & Cement Co., for many favors extended them during the progress of their investigations. The visitor who approaches Rondout by boat on the Hudson river has his attention atiracted by a prominent hill which rises steeply back of the lower town to hights of 250 to 300 feet. This is the Vlightberg and the steep cliffs on the side fronting the river are largely due to the quarries opened along the beds of 1178 NEW YORK STATE MUSEUM waterlimestone which have during the past sixty years or more been mined here for use in cement manufacture. The Vlight- berg, with a length of about 14 mile and a width of 14 mile, lies with its longer axis in a northeasterly direction in the city of Rondout between Hasbrouck avenue on the southwest and Dela- ware avenue on the northeast, and constitutes a prominent ridge which separates the southeasterly portion of the city of Kingston into two parts, an eastern part known locally by the old name of Ponckhockie, built on the plain near the river, and a western part, Rondout, occupying the valley south and west of the Vlight- berg. To the northward of the Vlightberg, the ridge is continued through the wooded “ North hill,” for about 2 miles to the vicinity of Kast Kingston where it becomes less prominent. At various points throughout its course its eastern face is very steep, as at “steep rocks,” and near Terry’s brickyard, and at a point east of Cloonan’s quarry, indicated on the map by C, Delaware avenue passes across the ridge through a narrow east and west gap. The southwest end of the Vlightberg terminates in steep cliffs over- looking Hasbrouck avenue, to the southwest of which street the land surface is low and hidden under the buildings of Rondout. The western slopes of the Vlightberg and of the North hill, as we will designate that portion of the ridge lying north of Delaware avenue, while locally steep, are not so high and do not present such precipitous bluffs as are seen on the eastern slopes. All along the western side of the Vlightberg ridge is a valley about 144 mile wide, with its bottom at levels varying from 75 to 200 feet A.T., which separates the Vlightberg ridge from the plain on which the city of Kingston is built. The eastern edge of this plain is formed by the Esopus grit, and the Onondaga limestone is ex- posed on it in a series of low anticlinals forming a belt about 34 mile wide. The city of Kingston proper lying still farther west is built on the alluvial plain of the Esopus valley, which, with an elevation of about 175 feet, extends from near Stone- ridge, about 8 miles southwest of Kingston, to Mt Marion, 7 miles north of the city. This plain is underlain by shales of the Marcellus and Hamilton formations deeply buried beneath allu- vial deposits.

The particular district in which we are interested, that lying within the small quadrangle on the accom: panying location map [pl. 1], lies at the eastern edge of the Little Mountains along the line of maximum folding, and at the apex of the angle which marks the change of trend of the folds from a southerly to a more southwesterly direction. This fact will be better understood by reference to the geologic map of New York State on which the exposure of the Helderberg lime- stones is shown to bend at Rondout sharply to the southwest through an arc of about 25 degrees. This change in the direc- tion of outcrop is not due to erosion only, but is caused in great extent by variation in the directrices of the folds and thrusts, and is related to the presence of numerous interlocking thrust planes of small width which have been observed in the cement mines and in the quarries of the Becraft limestone. The geologic map [pl. 2] is a sketch map based on part of the Rhinebeck quadrangle of the United States Geological Sur- vey topographic atlas, and is approximately correct. The areal distribution of the formations is indicated by symbols which are used also in the cross sections. The italic capital letters on the cross sections are explained in the legend of the map.

In color they are, when fresh, olive gray and, when weathered, dark gray, brown or blackish. They outcrop along the eastern base of the Vlight- berg, have been exposed in some of the underground work- ings specially in the Level and the Middle quarry, and they may be seen to better advantage on Kingston Point, along the right bank of Rondout creek at South Rondout, and in the high hill known as Huzzy hill about 2 miles south of Kingston. Their thickness can nowhere be accurately measured, but it is certainly over 1000 feet. At some points thin layers of black shale are inter- calated in the sandstone, as at the Middle quarry and on Kings- ton point. Some of the heavier layers of sandstone have their surfaces dotted with flattened pebbles of dark shale from 14 to 2 inches in diameter, which appear to have been soft mud when they were deposited there. These sandstones seem to have been largely of shallow water or even of beach origin, for cross bed- ding is common and at some points, notably at the entrance to the Middle quarry, the thinly bedded sandstones with shale part- ings show ripple marks and sun cracks. Fossils are rare. Some thin calcareous layers 1 to 3 inches thick and very difficult to find, contain abundant water-worn individuals of Plectam- bonites sericea, and Dalmanella testudinaria; and a few graptolites have been found in the shale on Kiagston point. The Champlainic sandstones are found, in all cases where the contact has been exposed, to be sharply and distinctly uncon- formable to the overlying limestones of the Upper Ontaric (Silurian), as described below. Ontaric or Upper Siluric Only the upper members comprising the Cayugan series of the Ontaric system are represented in the Rondout section; the lower members, including the Niagaran and Oswegan series, are absent and their time periods are indicated by marked un- conformity between the upper Ontaric limestones and the subja- cent Champlainic sandstones. The Ontaric formations may be grouped under three heads; the upper Manlius limestone; the 1182 NEW YORK STATE MUSEUM middle cement series, comprising the Rondout, Cobleskill and Salina waterlimestone; and the lowermost Wilbur limestone. These formations are exposed along the steep eastern slopes of the Vlightberg and North hill where they are found dipping at high angles into the hills to the northwest; and some portions of the series, specially the Manlius limestones, are exposed above the overthrust on the North hill, and also below the Vlightberg overthrust plane along the road running to the top of the Vlight- berg at the point marked K on the map. Wilbur limestone This lowest member of the upper Ontaric limestone series lies unconformably on the eroded edges of the tilted Champlainic sandstones. It is a dark colored argillaceous limestone 5 to 7 feet thick, which on weathering turns brown. In places it is highly fossiliferous, containing corals, crinoid fragments, brachi- opods, mollusks and some trilobites. The fauna of this lime- stone, which has long been known as the “ coralline” and which has recently been termed Wilbur limestone, is described in Mr Hartnagel’s paper in another part of this volume, and details of the unconformity at the base of the Wilbur beds are described below [p. 1209]. Cement series, comprising the Salina, Cobleskill and Rondout beds These cement beds have been variously called Salina, Water- lime, Manlius, Onondaga etc., and till recently [see Hartnagel’s paper on Preliminary Observations on the Cobleskill (‘ Coral- line”) Limestone of New York, p. 1109] no attempt has been made to definitely correlate them with any portion of the Siluric section of western and central New York. They consist of nine distinctly marked layers of limestone aggregating about 32 feet in thickness. The following detailed section of the strata exposed in the Spring and Delaware avenue quarries where the softer beds have suffered the least amount of crushing, and which shows the relations of the cement beds to each other and to the under and overlying formations, may be taken as typical of the Vlight- berg vicinity. The names given to the cement beds are those applied by the miners.

Salina Comprising the dark cements 3 The “footledge,” of hard, fine grained, almost black lime- ' stone, varies from 6 to 24 inches in thickness. The upper 6 or 8 inches are of exceptionally fine grain and are used for cement. The lower portion is rough and fossiliferous containing crinoid fragments and Tentaculites which are best seen when the stone happens to have gone through the kilns. 4 Soft black cement. A solid bed, 4 feet 5 inches thick, of dark limestone of finer grain than 3, and with some fossils in middle portion. 7 1184 NEW YORK STATE MUSEUM © Hard black cement, 4 feet 8 inches thick, is much like 4, but it is somewhat harder, breaks with a more conchoidal fracture, and it often has irregular dark blotches on an olive-gray ground. Cobleskill oa The middle ledge is a 7 inch band of somewhat shaly slightly more calcareous limestone that can usually be separated from the top of the hard black cement as a distinct bed. This band is highly fossiliferous, but the fossils can scarcely be seen in the fresh rock, and they appear best after the rock has been burned in the kilns. A large species of Leperditia is abundant, and Orthothetes hydraulicus and Rhynchonella lamellata are present. This middle ledge of the Vlightberg is, as demonstrated by Hartnagel, the attenuated eastern exten- sion of the Cobleskill limestone of the Schoharie section. Rondout beds Comprising the light cements 6 Hard gray cement, 5 feet thick, is a solid bed which on cross section shows horizontal bands of olive-green on a lighter gray ground. The rock has a splintery fracture; is of very fine grain at top and center, and at bottom is quite coarse. 7 Soft gray cement, 3 feet 3 inches thick, has a more even tone of slightly darker gray than 6, and is of finer grain and more conchoidal fracture. 8 The “curly” is a 19 inch band of dark gray, fine grain cement rock with undulating lamination, which is usually much sheared and crushed to a dark powdery mass by lateral move- ment of the overlying formations. It is to be noted that in general the lower part of each cement layer is of coarser grain than the upper part, except in the — hard black cement which is a smooth stone throughout. Some quartz sand is found in all the layers excepting the hard black. It occurs in the form of well rounded minute grains of limpid quartz scattered irregularly through the limestone, and from its resemblance to the wind-blown sand of deserts, it may be consid- ered to have been brought by. the wind from some near-by arid lands which bordered or inclosed the mud flats of Neontaric time. ‘kydvaZodoy yuasord oy} poonpoid py woIso1o o10joq puw Sury[Ney 10478 © uoIjIsod oY} o}¥oIpUT UOT}oos Jo JouIO Joddn yySII 4e spoquiAs YIIM Yoo oy} pu oovjins puL] otf} eAoqw Soul] poop SLL “ih ee diees te Ser rachiaite Moped spoq Jo Svap pxvaysom puw ysnayyoro Surmoys ‘Arrenb surly oy 7?

REPORT OF THE STATE PALEONTOLOGIST 1902 1185 9 The Leperditia bed, about 25 inches thick, forms the roof in most of the underground cement workings. It is a persistent band of tough black shaly limestone, and is full of the shells of Leperditia alta, which show plainly on the gray weath- ered surfaces of the thin layers into which this formation splits. The Leperditia bed is well exposed in the hanging wall of the several quarries on the Glory hole vein along the eastern slope of the Vlightberg, and also at the old cement opening on the hill- side over the White lime quarry on the North hill. At the latter point the following species were obtained: Leperditia alta (aa), Beyrichia sp.? (aa), Modiolopsis dubius Hall, and Spirifer vanuxemi. 10,11 Above the Leperditia bed are two bands of yellowish limestone, aggregating 7 feet, 7 inches in thickness, which break up into polygonal blocks [see pl. 6] formed apparently by shrink- age cracks similar to those seen in drying mud, and this resem- _ blance is rendered more striking by the concave plates into which the blocks readily split along planes parallel to the stratifica- tion. Local names are given to different portions of these two beds, which might perhaps more properly be considered as a single formation. The lower 22 inches is called the ‘“ streaked ” because of its horizontal dark lines; the ‘“ prismatic” or “ five point,” 32 inches thick. breaks up into mostly pentagonal blocks 4 to 6 inches in diameter; the “ paving block” or “ mud crack,” 15 inches thick, breaks into larger polygonal blocks of 6 to 10 inches diameter; and an uppermost 24 inch layer consists of gray weathering impure silicious limestone. Portions of these two beds make good cement but as a rule they are not quarried because the rock above them does not form a safe hanging wall or roof. . : Manlius limestone Beds 12-19 The Manlius limestone, aggregating about 42 feet in thick- ness, consists of eight beds of generally black or bluish gray limestone, with many intercalated thin beds that weather to a light gray. The lower beds, 12 to 16, contain the species so characteristic of the Manlius fauna: Leperditia alta, 1186 NEW YORK STATE MUSEUM Spirifer vanuxemi, and Stropheodonta vyvari- striata. A few of the gray weathering bands just below and just above the Stromatopora bed contain a gastropod fauna. Bed 17, with a thickness of 7 feet, 6 inches, is a veritable coral reef, consisting almost entirely of species of Stromatopora, which are found also more sparingly in the underlying bed, 16. The asso- ciation between the gastropod fauna and the coral reef is note- worthy. The uppermost layer of the Manlius, 19, is a heavy bed of fine grained, dove-colored silicious limestone, 6 feet, 4 in- ches thick, and is apparently barren of fossils. It forms the lowest bed of the Delaware avenue quarry. The upper surface of this dove limestone is curiously irregular and its contact with the dark overlying basal member of the Coeymans limestone is very sharp. There appears some evidence that the surface of the Manlius was slightly eroded before the Coeymans was deposited on it. Where exposed to the weather for a short time the black limestone can be readily separated from the dove-colored rock and the contact is then seen to be of very undulating nature, as if the soft calcareous mud of the Manlius had been eroded by the currents of the transgressing Coeymans sea when the latter advanced on the sinking mud fiats or lagoons of the Manlius continental shelf.

The Onondaga lime- stone is not found on these ridges, but is exposed farther to the westward on the edge of the Kingston plain. Coeymans limestone A series of heavy beds of dark gray limestone, aggregating about 49 or 50 feet in thickness, is exposed along the crest of the bluff on the cast side of the Vlightberg and North hill, and also forms a ridge of some prominence above the White lim® quarry overthrust, which may be traced through the woods from the vicinity of Gross’s quarry to beyond Terry bench mark. The entire series is seen to best advantage in the Delaware avenue quarry where can also be seen the abrupt lower contact with the Manlius and the gradual upward transition into the overlying more shaly New Scotland beds. The component parts of the Coeymans limestone are as follows, in ascending order. 20 Basal bed.. 58 inches of irregular, marly limestone of dark gray color, which on weathering readily breaks up into small! nodu- lar pieces. It is full of fossils; crinoid fragments and brachiopeds -are common, and Lichenalia specimens of all stages of growth are particularly characteristic of this zone. On weathered joint planes this rock somewhat resembles the Stromatopora bed. The best places to collect fossils from this bed are in the Delaware avenue quarry, and on the first ridge west of the old cement workings above the White lime quarry. 1188 FAUNA OF NEW YORK STATE MUSEUM THE COEYMANS LIMESTONE 20 Lower basal bed Lichenalia torta Hall, very abundant.

At no single point 1190 NEW YORK STATE MUSEUM can a continuous section from top to bottom be examined, and the physical characters of the formation are such that it has suffered great deformation, which is manifested in the pro- nounced slaty cleavage, numerous small folds and local thrusts, all of which render determination of its thickness a matter of much difficulty. Portions of the New Scotland beds are exposed at several points. Among the best exposures are those at the south end of the vertical cut on the west side of the Vlightberg ; along the top of the Vlightberg; on the north side of Delaware avenue; between the Delaware avenue quarry and Gross’s lime quarry; in the foot wall of the White lime quarry; and in a low bluff at the west side of the small swale that extends northwestward from the Old quarry. This formation consists of dark gray shaly limestone bands alternating with frequent thin seams of gray semicrystalline limestone. At some points, as on Delaware avenue, sandy shales are present in the middle of the formation. The lower portion has considerable chert, which is often associated, as in the underlying Coeymans, with an abundance of sponges. The upper portion of the New Scot- land graduates by increased thickness of the limestone bands, which contain abundant “ scutellae,” into the lower portion of the Becraft limestone. This transition is very gradual and may be well seen in the White lime quarry, in the Old quarry, in the Vertical cut, and in the quarry which follows the out- crop of the Becraft limestone along the face of the hill at the northern end of the West Shore Railroad bridge at Wilbur. Several feet of the upper portion of the New Scotland beds are so limy, that they might with equal propriety be included with the overlying Becraft limestone, but the line between the two formations has been drawn at a well marked division plane, which indicates a stoppage or temporary change in the sedi- mentation.

It is virtually a con- solidated coquina, made up chiefly of fragments of brachiopod shells and crinoids. It is hard and solid and for this reason its 1192 NEW YORK STATE MUSEUM organic remains, which are exceedingly abundant, can be col- lected only with great difficulty. The lower portion of the Becraft is a bluish gray limestone traversed by many thin shale films which intersect the main bedding planes at small angles. The middle portion of the Becraft is a massive bed of hard light gray, white or pink crystalline limestone, 18 to 20 feet thick, made up entirely of organic remains, and running from 94 to 97% of lime carbonate. It is very homogeneous throughout and is accordingly one of the most resistant members of the series, and has suffered a smaller amount of deformation; though it is faulted and folded in considerable degree, it has no slaty cleavage. Both the upper and lower portions of the Becraft are of darker color and are traversed by thin shale films. These shale films seem to have afforded lines of weakness along which movements due to lateral compression have taken place, and these portions of the Becraft are accordingly more broken up than is the middle. The lower dark gray Becraft constitutes a series of limestone beds 10+-feet thick which graduate nicely into the thinner layers of limestone forming the subjacent New Scotland beds. There is however a well marked division plane between the two forma- tions. The upper Becraft, 6-+-feet thick, of somewhat darker gray lime- stone, traversed by films of darker shale, anticipates the condi- tions seen in the next overlying formation, the Port Ewen beds, and its upper limit is marked by a prominent division plane, The entire formation is replete with fossils, but the fauna has not yet been well worked out. At a few favorable points fairly good silicified fossils have been collected, but as a rule diagene sis within the limestone sediments has rendered the organic remains so indistinct that the majority of them can not be identified. This limestone is of considerable economic importance and lias been largely quarried in this vicinity, as well as to the south- ward and northward from here, for the high grade of lime which it produces when burned. The lighter colored white or pink mid- dle ledge furnishes the best lime. The vertical cut on the west side of the Vlightberg, Gross’s quarry on Delaware avenue, and REPORT OF THE STATE PALEONTOLOGIST 1902 1193 the White lime quarry, Old quarry, and Cloonan’s quarry extend along the strike of the formation northward. There are also extensive quarries in the edge of the Becraft on the hill between Port Ewen station on the West Shore Railroad and the Wilbur bridge over Rondout creek, and the transition from the New Scotland to the Becraft can be well studied on the hillside over the southeast portal of the West Shore tunnel, about 2 miles south from the Vlightberg. At a few points the Becraft limestone forms ridges of low relief, as is generally the case with such massive pure limestones, but it has as a rule suffered extensive denudation by solution and it occupies the hollows or lies under the lee of protecting ledges of the Port Ewen beds. On the North hill there are two “ veins ” of the Becraft, one in its normal position near the eastern edge of the hill, the second on the overthrust block, running parallel to the first vein and from 700 to 1100 feet west of it.

It was first noted by Davis [1883, p. 390], who called it the “ Upper Shaly limestone” in contra- distinction to the “ Lower” or “ Catskill Shaly limestone,” now * See Works mentioned in the text, p. 1227. 1194 NEW YORK STATE MUSEUM the New Scotland beds. Davis does not cite any particular lo cality where this formation can be seen, but this map [op. cit. p. 391] shows the formation, as understood by him, to be present in all continuous sections in the vicinity of the Vlightberg, the North hill, the Port Ewen section, and in what he calls ‘ the southwestern synclinal,’’ which extends southward for about 2 miles from the village of Wilbur along the western side of Ron- dout creek. Darton [1894, p. 303, 318, map and sections on pl. 4, p. 319-25] describes the occurrence and relations of this forma- tion in the vicinity of Rondout and southward toward Rosendale. At a later date, with the object of eliminating physical terms of nomenclature, Clarke and Schuchert [1899, p. 878] applied the name * Kingston beds” to this formation, and cited as typical the section seen along the West Shore Railroad southeast of the high bridge over the Rondout creek about 114 miles south of the Kingston depot, which had been examined by van Ingen and Ruedemann [Clarke, 1900, p. 73]. The term “ Kingston ” was however preoccupied and accordingly Clarke [1902, p. 666] sug- gests the name Port Ewen, taking it from the name of the West Shore station near which the formation is seen to best advantage. The Port Ewen beds lie between the Becraft limestone and the Oriskany sandstone and they consist of massive beds of impure siliceo-argillaceous limestones which slightly resemble the New Scotland limestones that lie below the Becraft. The minimum thickness, aS determined by careful measurements at different points in the vicinity of Rondout, varies from 110 to 160 feet, and the formation probably attains, in places, a maximum thick- ness of about 200 feet. The peculiar characteristics of these Port Ewen beds are best seen in the cuits along the West Shore Railroad between Port Ewen station and the southeast end of the high bridge at Wilbur, and in the prospect tunnel driven into the hanging wall of the White lime quarry on the North hill. Other favorable points for examining the formation are: on the hill- side over the southeast end of the West Shore Railroad tunnel at Wilbur, where the entire formation is seen lying between the Becraft below and the Oriskany above; on the top of the quarry in the Becraft limestone along the curved outcrop of the syn- clinal trough southwest of the Port Ewen railway cut; in the REPORT OF THE STATE PALEONTOLOGIST 1902 1195 hillside on the north side of Delaware avenue between Gross’s residence and Gross’s quarry; and in the vicinity of Whiteport on the Walkill Valley Railroad, about 5 miles south of Kings- ton. Two sections can be seen at Whiteport: one near the rail- way station shows the Port Ewen beds underlying the Oriskany sandstone; the other section in the bluff on the east side of the track about 1 mile south of Whiteport station, shows the Port Ewen beds, 180 feet thick, outcropping at the top of the bluff between the Becraft and Oriskany. The fresh rock of this formation can best be obtained in the prospect tunnel of the White lime quarry, which with a length of 152 feet has penetrated a thickness of 107 feet of the Port Ewen beds without reaching the chert near the top of the forma- tion. It is hard dark gray, evenly fine erained siliceo-argillace- ous limestone of very uneven fracture, containing a considerable amount of finely disseminated iron pyrites, which hastens the decomposition of the rock. One of the most characteristic fea- tures of this formation and one which renders it easily receg- nizable from a distance, and which is best observed in the rail- way cuts and on the hillside near the tunnel at the Wilbur bridge, is the presence throughout the greater part of the forma- tion of well marked concretionary nodules of purer limestone, which lie in lines parallel to the bedding planes of the rock. The fresh rock of the nodules is slightly lighter in color and it weathers by solution of its lime content much more rapidly than does the general mass of the formation. The residual material is a yellowish brown sandy mud rock or “rotten stone” which is easily carried off during rain storms, so that lines of cavities are formed in the exposed edges of the formation. These pock- ets of rotten stone often contain well preserved silicified fossils. - With exception of the lowermost) portion of the formation, which, through a thickness of 10 or 12 feet just above the Becraft, consists of lighter colored, more fossiliferous, purer limestone, the general mass of the Port Ewen beds is not prolific of organic remains. They can not be obtained at all from the fresh rock (except in the basal layers), but careful search of the weathered surfaces and specially of the rotten stone pockets, will yield a considerable amount of satisfactory material in the form of 1196 NEW YORK STATE MUSEUM molds and casts. Such material formed the basis of the list of Species given by Clarke in his description of the section along the West Shore tracks near Port Ewen station [1900, p. 73]. A certain superficial resemblance exists between the Port Ewen and the New Scotland beds, and as this resemblance may lead, and indeed has led, to confusion on the part of students and others who make hurried visits to the region, it may be well to describe some of the characters by which the two forma- tions may be distinguished. The New Scotland beds are aiternating series of bands of shale and limestone, with lines or seams of nodular chert in the lower portion, and the entire series is replete with organic remains. The basal New Scotland is a shaly, blue gray limestone, abound- ing m the shellsof Gypidula galeata. The upper portion of the New Scotland gradually changes from a dark gray shaly limestone to a bluish gray limestone, and finally merges into the heavy beds of the Becraft through gradual increase in the thick- ness oi the purer limestone seams and a corresponding diminu- tion of the shale content of the mass. The Port Ewen beds, on the other hand, commence with an impure limestone, without chert, little different from the upper part of the Becraft, which by increase in frequency and thickness of the undulating seams of yellowish shaly material, and corresponding loss or diminu- tion of the lime seams, assumes within 20 feet above the top of the Becraft the typical character of the Pert Ewen beds. This typical character is that of massive dark gray, impure limestone that weathers brown and that contains lines of nodules of purer limestone which form cavities in the weathered rock surfaces. Toward the top of the Port Ewen beds the rock changes from the even grained dark limestone, which persists through a thick- ness of about 100 feet, and seams of black chert become intercal- cated in the layers of limestone. These chert layers increase in thickness, the limestone diminishes in thickness, and finally lay- ers of pebbles appear to indicate the proximity of the overlying Oriskany sandstone. The chert layers, aggregating 11 feet, 3 inches, in the Port Ewen section, and of slightly greater thick- ness toward the south near Whiteport, seem to mark the upper part of the Port Ewen beds at all points where this formation REPORT OF THE STATE PALEONTOLOGIST 1902 1197 has been observed. The lowermost beds of black chert at the base of the Oriskany seen in the east bank of Esopus creek just below the iron bridge where the Mt Marion to Glasco turnpike crosses the creek below Glenerie, about 7 miles north of Kings- ton, are considered to represent the chert beds of the upper part of the Port Ewen formation, though the characteristic Port Ewen limestone beds have not yet been recognized in the vicinity of Glenerie. Another point of difference between the New Scot- land and the Port Ewen is relative scarcity of fossils of the latter formation. Both Davis and Darton emphasize the prominence of the slaty cleavage of the “Upper Shaly” beds. Our observations in various parts of the region have demonstrated that cleavage is far more prominently developed in the New Scotland than in the Port Ewen beds. This would be expected as the New Scotland limestones and shales are much the softer and less resistant beds. The fauna of the Port Ewen beds is strictly Helderbergian in its expression, no true Oriskany species have yet been found in it, though many of its members are also found in the Oriskany fauna. The list published by Clarke [1900, p. 73] contains the names of species found in the various layers of the formation exposed in the Port Ewen railroad cut. New material obtained from the lower part of the formation along the edge of the hang- ing wall of the White lime quarry affords the following list of species.

The lower portion is a pebble bed or conglomerate 6 to 18 feet thick; the upper portion, 20 to 50 feet in thickness, consists of layers of sandy limestones intercalated with bands of cherty limestone, both of which are replete with fossils. The difference between the typical Port Ewen and the pebbly Oriskany is very great though the change from the one formation to the other was not violent, as indicated by the following de- tailed section measured on the West Shore Railroad cut about 14 mile south of the Wilbur bridge.

The cement matrix is rarely calcareous, so that this rock resists erosion and decomposition better than other members of the series. Throughout the bed are scattered, sometimes abundantly, much waterworn fragments of Oriskany shells. 29-34 Sharp on the top of the black pebble bed lies a series of siliceous and sandy limestones in thin layers of 4 to 12 inches thickness, which when fresh are very hard and of black or dark gray color, but which when weathered turn into a soft brown rotten stone. These beds with a thickness of 42 feet in this section, constitute the highly fossiliferous Oriskany which has yielded such finely preserved silicified fossils, and of which the upper layers are absent in this section. The entire thickness of this upper portion of the formation approximates 50 feet, in this immediate vicinity. North of Rondout the thickness of the Oriskany diminishes to about 20 feet at Glenerie. Darton’s figures of the thickness of this formation [1894, p. 497] can not be depended on. In the Rondout region, where Darton says it is “30 feet, including the conglomeratic member,” we find it to be at least 60 feet, with the upper portion removed by erosion. A carefully measured section of the Oriskany, including the pebble bed at the base, but without the top layers which here also have been removed by erosion, along the railway at Whiteport station, shows 70 feet, 6 inches of this formation, while Darton [op. cit., p. 497] states “In the Whiteport region and southward the formation con- sists of a silicious limestone bed which has a thickness of frem 8 to 9 feet.” On the top of the hill 1 mile south of White- port station, the total thickness of the Oriskany is about 80 feet. Ries, in his Report on the Geology of Orange County N. Y. (N. Y. State Geol. 15th An. Rep’t. 1897. 1:402), gives the Oris- kany in the vicinity of the Neversink valley north of Port Jervis a thickness of 125 feet. This thickness increases to the south- ward, as noted by Weller [1903, Geological Survey of New Jer- sey, Report on Paleontology, 3:93] who quotes 170 feet for the Oriskany in the Walpack ridge a few miles south of Port Jervis. The Oriskany of New Jersey contains a fauna, that of the 1200 NEW YORK STATE MUSEUM Dalmanites dentatus zone, which is apparently older than any so far recognized in the Oriskany of New York. This “dentatus fauna” comprises, according to Weller, in addition to a number of Lower Helderberg species and species peculiar to itself, the following Oriskany types: Stropheodonta magnifica, Spirifer murchisoni, Cyrtina ro- strata and Orbiculoidea ampia. It seems to occupy a horizon corresponding to the upper part, possibly to the black cherts, of the Port Ewen beds of the Rondout and Whiteport sections. The limit between the Port Ewen and the Oriskany has been drawn by us at the bottom of layer 27, the white pebble bed which marks the commencement of new and peculiar conditions of sedimentation and life of Oriskany time. That the pebble beds owe their origin to currents of considerable strength seems evident from the nature of the fragments of which they are com- posed. The pebbles themselves are in all respects small copies of the rolled white quartz pebbles that compose the massive Shawangunk grit, and their source is perhaps to be sought for in masses of this latter formation, which, during that early Deyonic time, projected above sea level in the vicinity of what are now the Shawangunk mountains along the eastern shore of the mediterranean basin or trough in which the Helderbergian and Oriskanian sediments were being deposited. No unconformity can be distinguished between the Port Ewen and Oriskany, though small rolled fragments referable to the Port Ewen black chert occur frequently in the Oriskany beds. The Oriskany pebble beds are well exposed in the small ridge just west of Gross’s residence; farther to the north they are seen along the western slope of the North hill where they are overlain by the upper sandy and cherty limestones of the same formation. Another excellent exposure, where the loose gravellike character of the lower pebble bed is well shown, is along Abeel street that runs from Rondout south along the left bank of the Ron- dout creek at a point near the old coal docks and about 14 mile north of the South Rondout ferry. The pebble beds are quite constant throughout the southern part of the Little Mountain belt, and they are recorded by Davis REPORT OF THE STATE PALEONTOLOGIST 1902 1201 and Darton as occurring, with diminishing thickness, to the northward as far as Catskill creek. No such clear quartz sand- stone as that of the classical Oriskany localities of Union Springs, Oriskany Falls and Schoharie, has yet been found in the Little Mountain belt. To the southward the pebbie beds have been noted as far as Rosendale, and there is no evidence that they do not extend beyond that point. They are not, how- ever, mentioned by Ries from Orange county, and in Weller’s Walpack ridge section in New Jersey, there is a hiatus at the horizon where they might be expected to occur. The upper sandy and cherty beds of the Oriskany are filled with fossils, and at many points, specially where the beds have slightly inclined attitudes permitting the surface waters con- taining vegetable acids to seep through the joint cracks and dissolve the calcareous cement, pockets of residual sandy mud contain abundant, exquisitely preserved, silicified fossils, that rival and often surpass the noted specimens from Cumberland Md. The best collecting grounds for this material are: in the West Shore Railroad cut between Port Ewen and the Wilbur bridge; on the Waikill Valley Railroad at Whiteport; along the western slope of the North hill at Rondout, beginning a short distance north of Gross’s house and extending to and beyond Terry triangulation station. But by far the best locality and one from which in the past the senior author has obtained large and fine collections (now in the possession of Dr John M. Clarke of Albany, and Prof. H. S. Williams of Yale University) is along the right bank of Esopus creek between the Glenerie lead mills and the iron bridge on the Mt Marion to Glasco road. This locality is about 7 miles north of Kingston, and 114 miles east of Mt Marion station on the West Shore Railroad. Here the beds are exposed, dipping about 15° to the westward, in broad areas along the roadside and the bank of the creek, and search in the decomposed material along the joint cracks has brought to light a wealth of fossils, in a state of preservation unequaled elsewhere in New York State. The fauna obtained there, of which an incomplete list is given, comprises upward of 125 species, a large number for a single bed at a single locality. : es 1202 NEW YORK STATE MUSEUM Several of the species mentioned in the Glenerie list have been found in the various other localities about Rondout, but no record has been made of them. This Glenerie fauna is quite as large as that of the Becraft mountain Oriskany, described by Clarke [1900], but differs from it in some important respects, of which the most notable is the larger proportion of New Scotland species present in the Glen- erie beds. No comparison can yet be made between the pelecy- pods and bryozoans of the two faunas, as these organisms in the Glenerie collections have not been identified. The large percentage of New Scotland species (26 out of a total of 94) in the Glenerie Oriskany emphasizes the close affin- ities between the Helderbergian and Oriskanian faunas. Indeed the Glenerie fauna and the beds containing it present essentially a recurrence of the conditions of sedimentation and of the fauna of the New Scotland beds during Oriskany time. The true Oriskany element of the Glenerie fauna (represented by such species as Edriocrinus sacculus, Rhipidomella musculosa, Leptaena ventricosa, Leptostro- phia magnifica and L. magniventer,~ Hip- parionyx proximus, the large Camarotoechias, Spirifer arenosus and S. murchisoni, Reas- Sselaeria ovoides, Megalanteris ovalis, Beachia SsSuessana, Actinopteria arenaria, etc.) is con- sidered by us to have been derived by migration from a contem- poranecus fauna which occupied an adjoining basin or trough farther to the westward, under somewhat different bionomic con- ditions. Instead of considering the eastern calcareous beds as Lower and the western arenaceous beds of the Hipparionyx fauna as Upper Oriskany, as suggested by Schuchert, we are disposed to follow Clarke in regarding these two types as presenting two distinct contemporaneous facies of the Oriskany. At no point have these two facies with their distinct faunas been found superimposed in a single section, nor have they been found in close proximity to each other. We do not include in this sug- gestion of contemporaneity the Oriskany-Onondaga fauna of Ontario, Canada, which is undgubtedly of later age. The pres- REPORT OF THE STATE PALEONTOLOGIST 1902 1203 ence of the genus Ambocoelia, and of the fish spine, Mach- aeracanthus sulcatus, both Devonian types, in the Glenerie fauna is noteworthy in this connection.

Its thickness is 300 to 325 feet. Itisa heavy bedded, soft, argillaceons grit of dark olive-brown color and of remarkably even grain throughout its mass, and it is quite barren of organic remains. It has well developed slaty cleavage, which often obscures the deposition planes of the rock, and on its weathered surfaces it breaks down into rounded hil- locks covered with small angular fragments of the stone. Its lower beds are quite heavy, somewhat harder in texture, and their bedding planes are covered with the fucoid Spirophy- ton caudagalli Vanuxem. The formation can be well seen in the high bluffs overlooking the left bank of the Rondout creek just north of the Wilbur bridge, and also in the cuts of the West Shore Railroad between — the Wilbur tunnel and the Wiltwyck cemetery. It is also finely exposed in the left bank of the Esopus creek at Glenerie its type locality. Its upper layers become more limy and finally, through grad- ual changes they merge into the argillaceous limestones of the lower portion of the Onondaga beds. This transition can be well seen in the West Shore Railroad cuts south of Kingston station, and in the banks of Esopus creek beneath the West Shore bridge at the Glenerie falls. The only fossils found in this formation are Leptocoelia acutiplicata, Atrypa spinosa, an obscure Disci- noid brachiopod and Spirophyton caudagalli. REPORT OF THE STATE PALEONTOLOGIST 1902 1205 Onondaga limestone This formation is not found on either the Vlightberg or North hill, but as it is one of the most important members of the series in the Kingston region, a few words are devoted to its character- istics. The upper part of the Esopus grit merges into the lower portion of the Onondaga by such gradual changes that no line of demarcation can be drawn. These lower impure limestones are about 40 feet in thickness, and they are overlain by about 30 feet of purer blue gray, hard silicious limestone that lies in beds of from 1 to 5 feet thick. The upper portion of the pure limestone carries considerable black chert that projects as irregular knobs on the weathered surfaces of the rock. This formation abounds in fossils, but the rock is so hard and splintery that they are very damenit to” extract. *Atrypa:reticularrs;*’beptsé- strophia perplana, Platyceras dumosum, Leptaena rhomboidalis, are the most common species. The Onondaga limestone is well exposed along the West Shore Railroad between the Wiltwyck cemetery and the tunnel; several quarries have been opened into it within the Kingston city limits; and it is also finely exposed along the western ‘slope of the mono- clinal ridge that parallels the east side of the West Shore Railroad for several miles north of Kingston, specially in the vicinities of Lake Katrine, Glenerie falls, Mt Marion and Saugerties. B Range of the Helderbergian and Oriskanian species The following table shows the range of the various species of fossil organisms throughout the members of the Helderbergian and Oriskanian series in the Rondout region. The table is based on the lists already given in the text above; and Clarke’s list of the Port Ewen fauna, published in his Becraft memoir [1900, p.73], has been incorporated. The relative abundance of the species is indicated by letters: a=abundant, c—common, r—=rare, v—present. 1206 NEW YORK STATE MUSEUM q g > 3 6) | & E ° 4] Hindia fibrosa Roemers... 00-26 »aa.

REPORT OF THE STATE PALEONTOLOGIST 1902 1209 STRUCTURAL FEATURES The cross sections on plates 8, 4 and 5 portray the large tectonic features of the Vlightberg and North hill. No attempt has been made to illustrate in these sections the smaller folds and faults which are so numerous in all the quarries and mines. Illustration of these details is reserved for a future paper. The term “ vein” is employed in the Rondout region in a sense similar to that in which it is used in the coal regions, namely for a single layer or for a composite series of layers of sedi- mentary rock quarried for economic purposes. It has no rela- tion to and should not be confounded with veins of metallic ore deposits. The compass readings here given have all been reduced to true meridian on the basis of 9°30’ west declination for Rondout. The unconformity between the Wilbur limestone and the Champlainic sandstone The Wilbur limestone and the underlying Champlainic sand- stone and shale are sharply unconformable at all points in this vicinity where the contact of the two formations can be observed. It can, however, be seen only along the east side of the Vlightberg and in the underground Vlightberg mines. The nature of this unconformity has been well described by Davis;+ and we can add only a few details to his description. The sur- face of the tilted sandstones at the unconformity, a surface which represents a very ancient plane (probably Eosiluric) of subaerial degradation, is much more uneven at some points than at others. At the locality marked U near the south end of the Vlightberg, where the unconformity was studied by Davis, and where our photograph [pl. 7] was taken to show the same view illustrated by Davis’s sketch [1883. p.3892], the eroded edges of the sandstone form a very irregular surface with hollows 6 to 24 inches deep. These hollows are in the nature of grooves parallel to the bedding planes of the rock, and the largest grooves coincide with the most prominent de- position planes, the latter having furnished lines of least resist- ance for the eroding agent. The hollows are filled with the “11883. p. 392-93; and 1890. p. 355. 1210 NEW YORK STATE MUSEUM Wilbur limestone, and in the limestone have been found rounded waterworn boulders of sandstone incrusted with fossil bryozoans and corals. Farther to the northward, at the Hill quarry, the old land surface of the sandstone is quite smooth, but still farther north, in the incline into the North quarry just west of the engine house (E on map, pl. 2), the same surface is again as rough as at the first locality. The unconformity is expressed not alone by the eroded sur- face of the Champlainic sandstones, but also by the discordant strikes and dips of the involved formations, which lie at nearly right angles to each other. At the locality U the sandstone strikes n. 10° w. (true meridian) with an easterly dip of 60°; and the Wilbur limestone strikes n. 55° e.; dip 30° n. w. This general attitude of the two formations is maintained at all points where the unconformity has been measured, though there is some variation in the relationship, which can be ex- plained by supposing the dip and strike of the sandstone to have been somewhat variable when the region was submerged beneath the Siluric waters of the Wilbur sea. At the angle of Union street, just south of locality U, the sandstone strikes n. 21° w., dip 60° e. On the old tram track below the Middle quarry, the sandstone strikes n. 24° w., dip 70° e.; and the Wilbur in the hill above strikes n. 49° e., dip 75° w. At the entrance to the Hill quarry, which is an excellent place to examine the un- conformity, the sandstone strikes n. 44° w., dip 50° n.e.; and the limestone strikes n. 41° e., dip 75° n. w. On the aR in the North quarry, which is just west of the engine house (marked E on map, pl. 2), the sandstone strikes n. 4° to 6° w. 2 aD 70° e.; and the limestone strikes n. 71° e., dip 10° w The nonconformity represents a period of Jand conditions in this vicinity which continued through the epochs of deposition of the Shawangunk grit, the Medina sandstone, the Clinton lime- stone and shale, and the Rochester shale and possibly the Lock- port limestone. All of these formations, absent from the Ron- dout section, were laid down farther to the westward and south- ward, as described by Hartnagel in his paper on the Cobleskill limestone. j : ; OU Sees Sa, pe NN ee Ae r a) ‘ ‘ G ; = er Brig ores cine eh ae ; fates wv et fe Pm N 1 1 PAN.

The axis of this arch passes through the point J, and just west of the point K on the map [pl. 2], and its western limb is exposed in the steeply dipping Vertical cut along the outcrop of the Becraft limestone [see V-V, map, pl. 2]. 4 An overthrust block of small extent and uncertain relation- ships, cut off by the fault 2-2 at the north end of the Vlightberg. 1 Glory Hole vein The most important feature of the eastern side of the Vlight- berg is the long deep cut made in the Glory Hole vein of the cement rocks, which extends with a general strike of n. 60° to 70° e. from the engine house (E) southwestward for about 600 yards to beyond the Middle quarry (M), where it loses its identity. ~ This “vein” of cement rock has an outcrop at least 20 feet wide that appears on the hillside at altitudes varying from 100 feet at the engine house to about 175 feet between the Hill and the Middle quarries. The vein dips into the hill at the steep angle of 75° to the northwest, and at the northeast end, be- tween the engine house and the Hill quarry, it has been exca- vated in the Glory Hole workings to a depth greater than 150 feet below tide level. In these deeper workings, and also in 1212 NEW YORK STATE MUSEUM the shallower workings along the vein near the Hill quarry and north of the Middle quarry, the same trend of n. 60° to 70° e., and dip of 75° n. w., are maintained with remarkable regularity in the foot wall of the vein. On the other hand, the trend and dip of the hanging wall of this vein are not so constant and they vary greatly in the vicinity of local disturbances of the cement beds. ; Toward the south side of the Middle quarry the Glory Hole vein assumes a flatter position, and at the point U, which is near its southernmost outcrop, its dip is 30° n. w. and its strike n. 55° e. While at certain points, as at about halfway between the engine house and Hill quarry, shown in the distance of the photograph [pl. 8], the Glory Hole vein is a simple vein about 20 feet thick, there are other sections where the vein has been duplicated and even tripled by diagonal strike faults, the planes of which intersect the vein at small angles, generally 10° to 20°. Such diagonal strike faulis, which are in all cases thrusts of small displacement with the upthrow or thrust on the north- west side, are best seen at the north end of the Glory Hole cut [pl. S and 9], at the Middle quarry [fig. 2, pl. 12], and at the Hill quarry. At one point near the south end of the deeper workings of the Glory Hole vein, such a diagonal fault brings up a wedge of Wilbur limestone, the angular crest of which rises toward the southwest. Following the Glory Hole vein through the Middle quarry toward the south end of the Vlightberg, we find that its dip decreases, and that it is split by a diagonal strike thrust fault, with upthrow on the northwest side, into two veins, which south of the Middle quarry give rise to two sharp though small ridges now capped on their northwestern slopes by Wilbur lime- stone, and showing Champlainic sandstones on their southeast- ern slopes [see pl. 12, fig. 2, 3, 4]. The right hand ridge, with a strike of n. 55° e., on which is the finely exposed section of the unconformity at locality U [pl. 7], is the continuation of the Glory Hole vein, which has veered somewhat to the southeast and which here has a northwesterly dip of only 30°.

The snow covered mass in foreground is top of a pier. REPORT OF THE STATE PALEONTOLOGIST 1902 1213 ridge, designated “vein B,” [pl. 12, fig. 3 and 4], with a strike of n. 60° e., dip 30° n. w., appears first as a small wedge-shaped block in the south side of the Middle quarry, the block increas- ing in size and hight to the southwest till it becomes of the Same prominence as that bearing the original vein. The north- westerly dipping Wilbur limestone on the western surface of this “vein B” block is broken in the trough at the bottom of the slope by a small fault, which separates it from the south- easterly dipping Wilbur limestone that covers the eastern limb of the anticline of the Taylor’s corner vein. This small fault coincides with the axis of a synclinal fold, which, though here broken, had a complete trough, now eroded, at no great distance to the southwest. Northeastwardly the amount of displace- ment along the fault plane increases rapidly, and at the Hill and Level quarries the two broken edges of the cement forma- tions are widely separated, how far is as yet undeterminable. At any rate this fault affords a clue to the puzzling relations of the Glory Hole vein and the eastern anticline. —s» 2 The eastern anticline At the southern end of the Vlightberg the Taylor’s corner vein of cement [pl. 12, fig. 3 and 4] is bent up into a sharp anti- clinal fold of northeasterly trend, the crest of which is distin- guished in the rounded ridge, covered by Wilbur limestone, that extends northeastward from the old Taylor’s corner engine house. The southern end of this anticline is cut off by erosion, and a good section of it can be seen along the southeast-north- west portion of Union street [pl. 12, fig. 4]. The eastern limb of the anticline is very narrow at this point, as it extends only to the fault in the bottom of the first trough east of its crest, a dis- tance of perhaps 40 feet. The western limb is of much greater width, and, with a dip of about 45° to the northwest and strike of n. 70° e., it slopes under the high overhanging escarpment of the Manlius and Coeymans limestones. This vein was ex- cavated for a considerable distance underground and it was found to be abruptly truncated along its entire western edge by a small overthrust fault of northwest dip and northeast strike [pl. 12. fig. 3] by which the Champlainic sandstones were 1214 NEW YORK STATE MUSEUM carried upward toward the southeast to form the hanging wall of the vein along its truncated edge. The amount of displace- ment along this thrust plane has not been determined, as no exploration in search of the missing vein has yet been made. The axis of the eastern anticline dips at a low angle to the northeast, as can best be seen in the northerly portion of the Taylor’s corner workings. The Middle quarry, which is next northeast of the Taylor’s corner quarry, shows a structure quite similar to that of the latter, namely an anticlinal arch dipping slightly to the north- east, its wider western limb dipping steeply to the northwest and finally being truncated by an overthrust fault which brings up the Champlainic sandstones into the hanging wall. The eastern limb of the Middle quarry anticlinal is however some- what different from that of the Taylor’s corner vein. It is wider, and steeper, and, after having been followed in the quar- rying operations for some distance, perhaps 150 feet, on its southeast dip toward the Glory Hole vein, it was found to curve sharply downward and to diminish in thickness and eventually to dwindle to a knife edge. Still farther northeast on the same anticlinal arch are the Level workings, which present essentially the same features in the form of the vein, with the exception that the anticlinal arch has here a small longitudinal trough on its summit just west of its crest. The barren, much contorted zone lying be- tween the eastern limb of this anticlinal and the Glory hole vein is crossed by two or three tunnels or crosscuts, and abun- dant evidence of slipping along northwesterly dipping planes can be found. The Spring quarry adjoins the Level workings on the north- east. Here also the anticline appears, but with a slight south- westwardly dipping crest, and with its direction changed toward the left to a strike of n. 42° e. This quarry is just north of the apex of the angle that marks the change in the directrices of the folds of this region, as already referred to on page 1179. The apex falls somewhere between the corner of Delaware avenue and the engine house, and in this small area we find structural features seen nowhere else in this region. North end of Glory Hole cut, looking from top of second pillar northeast toward the engine house. Note the folded and faulted gray cement in left side of first pillar, and the striated and scaly thrust plane at the bottom of the Pris- matic cement in the hanging wall. The foot wall is Wilbur limestone. er 4 REPORT OF THE STATE PALEONTOLOGIST 1902 1215 The western limb of the anticline has not been explored to a sufficient depth in the Spring quarry to enable us to state defi- nitely what becomes of it, and whether or not it is truncated by a fault in the same manner as are the veins in the other quarries to the south. There are on the surface of the ground some indications of a fault of northeast trend that crosses Delaware avenue at a point about 400 feet west of where the _tram track crosses the avenue at the angle, but the plane of a fault intersecting the surface of the ground at this point would pass several hundred feet west of the strike of that deep fault which truncates the veins of the Level and other quarries. The eastern limb of the Spring quarry anticline presents much the same features as shown in the other quarries. On the surface of the ground the anticlinal arch shows finely in the Delaware avenue quarry and in the stripped area west of the shaft house at the Spring quarry incline; and an ex- cellent sectional view of it looking in a southwest direction can be obtained on the flats from the old floor of the Spring quarry at the foot of the hill near the junction of Delaware avenue and Crane street. In the Spring quarry face and in the face of the Delaware avenue quarry, which lies above the Spring quarry, a continuous, undisturbed section of the Siluric and Lower Devonic formations as far as the New Scotland beds can be measured. The entire thickness of the Manlius and the under- lying cement beds is shown in the face of the old Spring quarry, and the base of the Coeymans limestone is seen breast high above the floor of the Delaware avenue quarry. On the south- east side the beds dip steeply toward the flats. The crest of the anticline is broad, so that the floor of the quarry is almost flat, and at the quarry face the beds show a slight dip to the northwest at the top of the western limb of the anticline. On the south side of Delaware avenue, between the Spring quarry shaft house and the engine house [pl. 3, sec. 3], is a small knoll of Manlius limestone, the beds of which dip about 30° toward the southeast. This knoll presents a fine example of “imbricated structure,” or “schuppen-structur” induced by several nearly parallel minor thrusts from the southeast. These thrusts are peculiar in that their planes, which are from 1216 NEW YORK STATH MUSEUM 12 to 15 feet apart, converge toward the surface of the ground. Their effect is to produce a quartet outcrop of the Stromatopora bed of the Manlius limestone, and greatly to increase the ap- parent thickness of the latter formation. There has been little crushing along these minor thrust planes, and a shear zone of only ;; to 1 inch thickness can be distinguished; but, neverthe- less, the opposing faces of rock have well developed slickenside surfaces. Close faulting with almost no shear zones is on the whole characteristic of the dislocations in the limestones of this region. These minor thrusts are very similar to some of those figured by Sir Archibald Geikie, 1888.1 The formation of these minor thrusts was probably imme- diately consequent on the plication of the anticlinal arches, and their origin is assigned to torsion forces that buckled the anti- clinal arch. A most interesting feature of the eastern anticlinal is the pair of approximately parallel tranverse thrust faults of north- easterly dip that transect the anticlinal arch and cut it into three segments. Little trace of these two faults can be distin- guished on the surface of the ground, but they have produced important complications of the underground cement veins. The Taylor’s corner vein, after having been worked out across the entire width of the anticlinal arch, finally dipped toward the northeast, its foot wall flattened, and the farther edge of the vein was truncated by a northeasterly dipping thrust fault which afforded a hanging wall of Champlainic sandstone. The southern end of the Middle quarry has a higher elevation than, and actually overlies the broken end of the Taylor’s corner vein, and it, in turn, at its northeastern end dips steeply and is cut off in similar manner by a thrust plane. Beyond this second thrust plane the same vein is being worked at a higher altitude in the south end of the Level workings. These transverse faults are all overthrusts from the northeast, and in conse- quence of their presence the segments of the eastern anticline have been “telescoped,” so that they overlap each other after the manner of a vertical row of earthenware tiles on a roof. 4 Recent Work of the Geological Survey in the Northwest Highlands of Scot- land.

Upper portion of figure occupied by Leperditia and Prismatic beds. See page 1220 a> d 7 on REPORT OF THE STATE PALEONTOLOGIST 1902 1217 We have here the only direct evidence seen in this vicinity of the existence of a compressing force acting from the northeast, and even this force may be indirectly due to the same torsion stresses that produced the buckling of the anticlinal arch. It seems appropriate to cite here other phenomena which we consider to have been caused by torsion forces acting after the formation of the main features of the region. Among them are: the virgation of the Glory Hole vein at its southern end; the small diagonal strike thrusts that intersect the hanging wall of the Glory Hole vein, and several similar thrusts seen in the Becraft limestone at the White lime quarry; the diverging minor thrusts of the Becraft limestone in the Vertical cut; and possibly also the small overthrust mass that caps the northern top of the Vlightberg. 3 The western anticline When passing over the Vlightberg along the line of section 1 [pl. 2 and 3] the Coeymans limestone is found faulted on itself over the hanging wall of the Glory Hole vein. This condition is best seen at the Hill quarry where the lower mass of Coey- mans limestone has fallen away from the overthrust plane into the quarry, leaving the deeply striated under surface of the thrust mass finely exposed to view. This thrust mass of Coey- mans, which dips at a high angle (almost 80°) toward the north- west, curves upward toward the top of the hill and becomes in- verted toward the northwest, and finally is lost just below the crest of the cliff along an approximately horizontal crushed zone that marks the presence here of a dispersed fault. Above this crushed zone the Coeymans limestone appears in its normal at- titude exposed in low ledges of northeasterly trend just east of the tenant house on the hilltop. These ledges of Coeymans extend along the entire eastern edge of the hilltop, with an exposure about 50 feet wide, and at a point about midway be- tween the tenant house and the edge of the Middle quarry their strike is n. 50° e., dip 60° n. w. At the Reeth end of the Vlightberg the strike of the Coey- mans and New Scotland beds veers to the west around the Spooning-up end of the small synclinal trough that occupies the northward-opening swale on the top of the Vlightberg. 1218 NEW YORK STATE MUSEUM Through the point marked J on the map, plate 2, passes the axis of the western anticlinal arch, on the crest of which are exposed ledges of Coeymans limestone that show in the field on top of the hill overlooking the Vertical cut. These Coeymans beds dip slightly toward the northwest. A short distance down the northwestern slope of the hill the New Scotland beds are found, and near the foot of the hill the steeply dipping Becraft limestone has been quarried in the Vertical cut [V-V, pl. 2]. The limestone in the Vertical cut stands nearly on edge, with a strike n. 75° to 80° e., and its apparent thickness is somewhat increased by a virgating series of several minor thrust faults. These faults radiate from an axis parallel to the strike of the limestone and located a short distance below the floor of the quarry, they cut the bedding planes of the limestone at low angles, and in each case the upward thrust is on the north- west side. : The bowl-shaped area just north of the point J is filled with drift deposits, so that its substructure can not be determined. 4 The Vlightberg overthrust The western and northern edges of this overthrust plane are marked on the map [pl. 2] by the heavy black line 2-2, and its position is roughly indicated on section 2 [pl. 3]. On the south side of Delaware avenue, just beyond the shaft house of the Spring quarry incline, there is a knoll showing an anticline of Coeymans limestone, the axis of which points south- westwardly across the fields toward the Vertical cut. The path that crosses the east side of this knoll leads under the cliff of New Scotland limestone on the north side of the Vlightberg and then joins the lane that runs to the tenant house on the hilitop. On the northwest side of the lane is a field with no outcrops of rock. The lane itself runs over Coeymans limestone which outcrops at intervals, dipping to the east at low angles. Along the left or eastern side of the lane the New Scotland limestone of the low cliffs is very much shattered and dips steeply to the northwest. Continuing on up the lane, the Man- lius limestone, with strike n. 20° e., dip 10° e., appears at the point K on the map, at the angle of the road where it turns up the hill toward the house. A little farther on, a low escarp: Plate 11 Faulted and folded beds of cement rock and Manlius limestone in face of cliff over the Glory Hole incline. This view is immediately above that shown in plate 10. See page 1220 <. REPORT OF THE STATE PALEONTOLOGIST 1902 1219 ment crosses the road diagonally and can be traced for some distance to the right into the field and in the opposite direc- tion toward the northeast into the woods. This escarpment is formed by the upper part of the New Scotland limestone, which has here a strike of n. 60° e., dip 55° n. w., and which marks the western edge of the overthrust mass. In the woods northeast of the lane a narrow strip of basal Becraft limestone overlies the New Scotland at the edge of the escarpment, also dipping steeply to the northwest. The contact plane of this overthrust can not be seen along the northwest side of the hill, but its course is plainly indicated by the topographic features, the sharp angulation of the slope, and the narrow gully which extends for a short distance through the woods along the foot of the slope. On the north and north- east side of the hill the thrust plane can be readily distin- guished, specially in the cliff over the Glory Hole and Level inclines. Here it is seen as a well marked plane cutting diagon- ally across the cement and Manlius beds at about the hight of the peak of the roof of the head-frame shed [thrust 2, pl. 11]. On the eastern slope of the hill, between the engine house and the Hill quarry, this plane seems to rise toward the southwest, and its location is soon lost, probably through dispersion of the fault. This thrust is from the southeast, and it involved in its move- ment only the upper layers of the eastern anticline, and shoved these a short distance along an almost horizontal plane toward the northwest till they rested on the southern limb of the western anticline. It seems to belong to the system of minor convergent thrusts, described on page 1215, as imbricating the Manlius limestone in the area north of the engine house. Its position is only a few feet above the uppermost of those thrusts, and its attitude is more nearly horizontal. We see no reason for associating this Vlightberg thrust with the much more ex- tensive White lime quarry overthrust of the North hill, described below. The outcrops of Coeymans and Manlius limestone along the lane probably belong to the southeastern limb of the western. anticlinal arch. 1220 NEW YORK STATE MUSEUM Contorted beds at mouth of Glory Hole Before leaving the discussion of the Vlightberg, we wish to call attention to the complex and highly interesting folding of the rocks over the mouth of the Glory Hole incline [see pl. 8 tu 11]. Of these plates, numbers 8, 10, 11 are adjoining views all looking southwestwardly from the engine house. Plate 8 is from the southeast corner of the engine house, looking along the Glory Hole cut. Plate 10 is a view of the lower portion of the cliff from the platform of the Glory Hole head-frame on the west side of the engine house. Plate 11 shows the upper portion of the cliff as seen from the western edge of the engine house roof, and its lower portion duplicates the upper portion of plate 10. The relations between plates 8 and 10 will be better understood when it is recognized that the small wedge of ce- ment rock in the top of the pillar in the right of plate 8 is the same wedge that shows to the left of the center of plate 10. It is shown also in the lower left hand corner of plate 11, where it is marked “gray cement,” and a view of its opposite side is seen in plate 9, where it is marked “H?.” Overhanging the Glory Hole incline is a long closed recum- bent underfold of Leperditia limestone containing a core of Prismatic cement. This fold can be traced along the foot of the cliff toward the right for about 30 feet, till it is lost in the vicinity of the Level incline. To the left of this fold, in the top of the pillar which was left to support this very unstable portion of the Glory Hole hanging wall, are wedges of cement rock, the structure of which is best shown in plate 9. These wedges are remnants of a faulted mass, produced by one of those diagonal strike thrusts described on page 121%, by which the Glory Hole vein was here duplicated to form what the miners call a “double vein.” Above the recumbent fold is seen the edge of a thrust plane [thrust A, pl. 11], that appears to be the continuation of the fault plane which produced the beautifully striated and scaly surface on the hanging wall of the Glory Hole cut, shown in plates 8 and 9. Next above is a series consisting of Leperditia, Prismatic, Paving block, and lower Manlius (beds 12-14 of sec- tion, p. 1183), which are terminated above by the almost hori- Plate 12 double anticline Level fig. fs 100 Z Sections across the Vlightberg and sketch plan of the southeastern corner of the Vlightberg to show the relations of the Level, Middle and Taylor’s corner veins of the eastern anticlinal arch to the Glory Hole vein, and also the virgation of the Glory Hole vein at its southern end.

Above this 2-2 thrust is more Manlius and, at the top of the view, the Coeymans limestone. The middle block, between thrusts A and 2, shows a very fine example of beds dragged beneath a thrust plane. The over- thrust mass above plane 2 moved in a direction n. 40° w. The broken edges of the under segment were caught by the moving mass, curled up, as shown at the left of the center of plate 11, again broken off, and a small intermediate thrust plane (thrust B) about 50 feet wide was formed. Along this latter plane the small broken off segments of the beds involved were carried along and actually jammed farther into the face of the cliff. Thrust B has a true overthrust plane at the edge of the cliff at the left of the picture which diminishes to a mere sliding plane between normally superimposed layers of the Manlius limestone at the right side of the view. The North hill and the White lime quarry thrust Sections 3, 4 and 5 of plates 8, 4 and 5, illustrate the structure of the North hill, which is very much simpler than that of the Vlightberg. With the exception of the extreme southeastern corner, the entire area north of Delaware avenue depicted on the map [pl. 2], exhibits a shallow synclinal structure with the beds at the eastern edge of the trough dipping steeply west- ward. The anticlinal arch seen in the Spring and Delaware avenue quarries does not constitute one of the structural feat- ures of the North hill, as its axis has an east-northeast trend that diverges from the almost northerly direction of the base of the hill slope. The strike of the formations on the North hill is generally about n. 20° e., excepting near Delaware avenue, where, in the vicinity of the Gross quarry and Gross residence, the strike veers to the southwest and west with a corresponding change in the dip to northwest and north. Farther west at the first intersection of the railroad with the avenue the southwest strike is again resumed in the Oriskany pebble bed. Along the line of section 3, which is about on the line of Dela- ware avenue, the various formations succeed each other. in nor- mal sequence of Manlius, Coeymans, New Scotland, Becraft, Port Ewen and Oriskany. There is evidence of diagonal strike 1222 NEW YORK STATE MUSEUM faults at a few points on this line, as in the south end of the Gross quarry, and in the ridge of Oriskany west of the Gross residence, by which the apparent thickness of the Becraft and Oriskany beds is somewhat increased, but the order of super- position of the formations is undisturbed. On the line of section 4, however, taken a few hundred feet north of the avenue, the conditions are quite different. The sequence of the formations is normal up to the Becraft lime- | stone of Gross quarry, and then a prominent thrust plane cuts off the Becraft, and above the plane is found the Manlius lime- stone. Above the Manlius and to the westward the formations are repeated in normal order; Manlius, Coeymans, New Scot- land, Becraft, to the western slope of the hill, which at the line of this section is cut into the almost vertical Port Ewen beds. Several hundred feet farther north the same conditions are found along the line of section 5, plate 5, which passes through the White lime quarry, W-W on map, plate 2. The White lime quarry overthrust fault, which is indicated on map, plate 2, by the heavy black line marked 1-1-1-1, has been traced by us northward from Gross quarry to where it passes just east of Terry triangulation station, and throughout this distance its position and horizon were found to be remarkably constant. It follows very closely the western edge of the east- ernmost Becraft limestone vein, and its location is usually in- dicated by a more or less prominent escarpment on the over- thrust side or by a gully of erosion in the somewhat crushed Port Ewen beds below the thrust plane. At the middle of the Gross quarry, about 200 feet north of Delaware avenue, the Becraft limestone strikes n. 70° e., dips 20° n. w., and has above it at the edge of the quarry face a few feet of lower Port Ewen beds, which are continued along the southerly slope of the hill to a point back of the Gross residence. At the north end of the quarry the Becraft strikes n. 65° e., dips 20° n. w., and its upper portion, the thin blue layers, are cut off by the thrust, above which the Manlius limestone appears with strike n. 80° e., dip 5° n. These Manlius beds just above the thrust plane are the thinly bedded, dark blue gray layers containing Spirifer vanux- "7Ys11 oy} UO UOISssedep eYyy ULOIy pollaenb useq sey euo}seUTTT yye1oog oy} puv ‘Aempvor oy} SutAT1opun ‘oanqord oyy jo soyUs0 oy} Adnovo spoq uomA 410g yy, ‘aur, Aavoy oy4 ventral we AO:Oro anal axis e ‘W= Growth axis in z: Anterior ) - PI2eIUOSOINeIS M:P sherry } Muscle impression P : Pallial sinus 1230 NEW YORK STATE MUSEUM theoretically if not actually has all values from 0° to 360°.

REPORT OF THE STATE PALEONTOLOGIST 1902 12381 In Noetling’s diagram, of which a copy is given on page 1229, it will be observed that coincident with these varia- tions in the angle of obliquity is the passage from the Dim- yarian into the Monomyarian. divisions. This brief statement of Noetling’s determinations should be supplemented by the reader with the perusal of the original paper or the English abstract as cited. In elaborating the genus Lunulicardium which is so exten- sively represented in the Intumescens zone of western New York I have secured some very delicate barite replacements of the valves of Lun. clymeniae which retain the protegulum and give some indications of the value of torsion of the shell as an ontogenic character and it has become possible also to make some observations on the probable phylogenic significance of the same feature. Lunulicardium has been commonly re garded as a bivalve with a long and wide byssal opening. Beus- hausen has shown that the beaks in a certain subdivision of the ’ Wie. 1-4 Umbonal parts of Lunulicardium elymeniae showing triangular area and the attitude of the prodissoconch with reference to the mature shell. The apex of the par iatea shell is directed obliquely backward and its posterior end is the umbonal point of the adult genus (Chaenocardiola) to which Lun. clymeniae be longs are opisthogyre. We have, in a memoir on the Lamelli- branchs of the Intumescens zone in New York, presented a careful analysis of the generic characters but it here suffices to state that the evidence’ supports the construction of the hiatus between the valves as a byssal orifice while the umbo of the adult shell and the 1232 NEW YORK STATE MUSEUM apex of the prodissoconch are distinctly turned away from the byssal cleft or backward. With this orientation of the shell the beaks are opisthogyre. The larval shell or prodissoconch lies with its apex or primitive beak directed downward or toward the postlateral extremity of the adult shell, so that the original posterior extremity of the larval shell actually lies at and constitutes the beak of the adult. This relation is shown in the accompanying figures. The shell has in growth actually twisted with reference to the animal and the axial line which we have marked o-a@ has apparently trav- eled through a large angle to reach the corresponding position in the adult, O-A. The muscula- ture consisted probably of a single adductor corresponding to M on Noetling’s diagram. This expresses itself on the best preserved internal casts as a simple moderately large scar as shown in the figure adjoining of Lun. hemicardioides or it may be an approximation of two central scars as seen in Lun.mtilleri. In the former the condition seems to be the Fic 5 Diagram giving outline of adult ; .

The inference therefore that Lunuli- cardium has little to do with the Dimyarians is supported by empirical evidence of a single adductor or median approxima- tion or fusion of two adductors. Hence orienting the shell as Monomyarian posited between Avicula (Opisthogoniacea) and Pecten (Symptogoniacea), on the basis of its muscular and byssal structure, we find that the critical angle is exact for the position. taken. We take this as excellent confirmatory evidence of the Monomyarian affinity of the genus. Stew! 4 cant lwike scweatone meal wise satiate aaat nord. Ye se scars e In following the torsion backward from the adult condition to the prodissoconch we find that it passes through the angles neces- sary to bring it with precision to the condition of the Protocon- chae and the relations of the axis in the latter also correspond with those of the prodissoconch!. I believe therefore that the prodissoconch stage is an actual representative of the Protocen- chae condition and that the stages of torsion of the Lunulicar- dium shell in subsequent growth are indicative of its phylogenic stages of progress toward the Monomyarian stock. This con- clusion is based wholly on external characters and the fact of actual observed torsion in the shell from youth to adulthood. The Protoconchae being theoretically the primitive lamellibranch condition, we may never come to know it except in this or a similar manifestation. The supposed position of the pallial line in this group, just within the hinge, is a feature on which the nature of our material permits no observation. ; The reader will note that we are here dealing with the exterior of these shells. Noetling’s figures are based on interiors; hence the relations of the latter and Our figures are reversed. SOME DEVONIC WORMS BY JOHN M. CLARKE Plates 27 and 28 Though trails and tubes of Annelids are of sufficient frequency in Paleozoic rocks to indicate the abundance of these creatures from early Cambric time onward, yet the actual bodies of worms -have been so seldom reported that an additional discovery of them seems to justify record. Paleozoic remains believed to be Annelid bodies of errant worms have been described from the Cincinnatian by Ulrich, and Ruedemann has recently given an account of certain leechlike worms called Pontobdellopsis from — the Utica shale of New York. We have before us a series of specimens taken from the upper Devonic of New York which seem to us correctly interpreted as bodies of Chaetopod worms directly allied to Aphrodite, the well known sea mouse of north Atlantic coasts which we have had abundant opportunity to study in its natural resorts. They have been collected from certain fine grained felspathic argillaceous flagstones belonging to the final phase of Portage sedimentation in the town of Italy, Yates county, and in the Tannery gully at Naples, Ontario county. Of one, whose structure seems rather the more puzzling, there is a number of specimens, of which in two instances we have opposite sides representing dorsal and ventral aspects, which it may be here said are not greatly unlike because the tenuity of the body substance save on the back has made the latter the predominant expression. These are all from the former locality. Hasty examination of these specimens might find in them a suggestive resemblance to the loose, detached rays of short armed Ophiurans. We call attention to this resemblance lest the sapient critic fall into travail at this point. Auother spe- cies is represented by several clearly defined examples from the Naples locality, where it is associated with Parop- sonema cryptophyum and some other unusual species. The basis of comparison of these with existing Errant Annelids lies in the apparent presence in both of a double series of trans- verse scuta or hardened overlapping plates on the back. Such structures are found among living Polychaete worms only in the REPORT OF THE STATE PALEONTOLOGIST 1902 1235 family Aphroditidae and we may here introduce so much of the characterization of these forms as pertains to the interpretation of the objects in hand. W. Blaxland Benham in the Cambridge Natural History [v. 2, 1896, Polychaet Worms, p. 309] says: The most characteristic feature of this family and one by which its members are absolutely distinguished from all other Chaetopods, is the possession of scales or “elytra” on the back. These flattened dorsal cirri are of a somewhat ' horny texture and are carried, generally, on alternate seg- ments of the body, filamentous cirri occurring on the other segments. In the ‘subfamilies eee and Polynoina the elytriferous segments are 2, 4, 5, 7, 9 etc., up to 238; then every third segment. The worms are Dain: baal with some thirty- five to forty-five segments, though Sthenelais and a few others have many more. In many cases these elytra are relatively of large size extending backward as broad scutes in two lateral series which may or may not meet and slightly overlap in the middle line. The posterior edge of each scute overlaps that next behind it. In the well known case of Aphrodite, the “‘ sea-mouse ” the elytra are covered by a felting of hairlike threads but Her- mione, an allied genus, has them fully exposed. The representatives of both of these genera are short, broad and oval worms. We find no statement as to the alternation of the scutes in these forms except that they are “arranged as in Polynoe ” where such alternation prevails in most instances. Among the Sigalionina which have longer vermiform bodies “the elytra are in alternate segments up to the twenty-sixth and posteriorly on every succeeding segement” [op. cit. p. 313]. Such structures represented by the combination of form and scute-bearing segments we find in our specimens, together with the presence in the case of one species of conspicuous and heavy tufts of marginal setae and in the other sparser hairs plainly arising from extended segmental pessRedia We briefly describe these specimens. 1 Four examples are elongate oval bodies having the outline of a short willow leaf, rather blunt at one end and tapering to a more acute angle at the other. Two of these specimens pre- serve both obverse and reverse of the body and the markings of one side are sharper than on the other; it is evident that they have been impressed from one side to which they properly ap- 1236 NEW YORK STATE MUSEUM pertain, into the other. The more strongly marked or by. analogy the dorsal surface carries a narrow median eleya- tion running from the blunt end to near the acute ex- tremity; it becomes continuously more obscure toward this end and may there fail to cause any interruption of the Surface. The more complete of these specimens carries about 55 transverse segments, others carry from 40-50 accord- ing to the degree of their completeness. These segmental di- visions are produced by oblique depressions departing from the axial line of the body, bending forward toward the margins but over the median and anterior parts becom- ing more transverse. These depressions bound the surfaces of oblique overlapping plates directed backward or toward tue blunt extremity of the body. The plates appear to be continuous across the full width of the body but are narrowest at the axial line and broader outward, their fore and aft width apparently being at about half the distance between the axis and the outer margin. Their edges are frequently broken off in detachment and the posterior plates appear to be longer and better defined than the others. These plates (if they are correctly thus interpreted) are rather narrower than similar structures in living species so far as our observation has extended and yet it is not clear to us what part of their actual width has been concealed by their oblique direc- tion into the matrix. The overlap is on the anterior surface of each plate and the projecting posterior edge could not have been greatly extended. Construing the structure thus given from a relief of the natural dorsal mold we note in addition to the midrib a low submarginal ridge on each side which anteriorly impresses the segments in such a way as to thicken each but posteriorly produces only Ds nuosity in the outline of the plates which is doubtless intensified by the breaking away of the edges of the plates themselves. Besides these there are obscure’ traces of other longitudinal lines. The posterior extremity of the body is blunt but the anterior end tapers narrowly and in some of the specimens terminates in a smooth blunt subcylindric process which resembles what the head should apparently be in such an organism. : REPORT OF THE STATE PALEONTOLOGIST 1902 1237 ‘Along the lateral margins are broad free fringes like matted - bunches of setae which may attain a length of nearly or quite half the width of the body. Al] the specimens show this char- acter but in one only do these present the aspect of a continuation near the posterior extremity of the edges of the dorsal scutes. One could conceive the thickenings of the margin by the sub- marginal ridges as due to the parapodia. The marginal filaments are usually directed backward, though they may turn forward toward the anterior extremity. The cast of the other, or ventral surface simply presents these various details of structure with some obscurity. These characters seein throughout so suggestive of the features shown by Aphrodite and Polynoe that we shall probably not be far amiss in associating these forms therewith; if not in direct association, at least with the Errant worms. For a designation therefore, we propose to indicate these objects as Pro- tonympha salicifolia. 2 The second series of these annelids is composed of much more elongate bodies like Phyllodoce or Nereis and are usually curled up in spirals. These are rather blunt at one end, main- tain a somewhat uniform width for most of their length but taper thence to a narrow extremity. The bodies are distinctly seg- mented, in the best preserved of the specimens there being upward of 100 narrow divisions which are separated from each other by tolerably deep depressions. In the axial line is a furrow which so divides the segments as to give each the ap- pearance of being in two parts. It is not evident that these segments were plated but the impressions which they leave in sandy sediments seem to indicate this as a possible condition. Each however bears at each margin a parapodium carrying a bunch of long setae making a fringe often wider than the body itself, and into these parapodia the segments seem to extend without interruption. The general expression of this structure is very like that of the long row of posterior segments in Chaetop- terus and there is also a notable similitude between the arrange- ment of the segments in the latter and that shown at the broad extremity of the fossil in question, and furthermore in the clear development of the median part represented by the axial line in + 2 12388 NEW YORK STATE MUSEUM - the fossil body. The single example of these worms which is not closelv coiled has the body partly fiattened and partly com pressed laterally so as to bring the setae into profile, but the other specimens (three in number) are more or less closely coiled and their structure, save the bristles, is not as distinctly set forth. These all have a certain resemblance to Iulus and other myriapods and the fact of their occurrence in sands where con- minuted remains of terrestrial vegetation have been freely a¢ cumulated, at first suggested this as their probable character. but the specimens do not on close examination reveal the structures of that group. This second group of worms may be designated as Palaeochaeta devonica. Geologic horizon and localities. All these bodies occur in the sands, flags and shales which in the Naples (Ontario county) section lie immediately above the layers which carry the last representatives of the Intumescens fauna. ‘These layers are locally known as the Hatch sands and carry very few fossils, Paropsonemacryptophyum, Orbiculoidea mag- nifica, a linguloid of peculiar aspect, Hydnoceras, with frag- ments of Lepidodendron and other plant remains. With one exception all are from the village of Naples, Ontario co. and Italy hill, 8 miles northeast in Yates county. A single example is from soft olive shales a few feet below the horizon of the Grimes sand- stone, Grimes gully, Naples.
