§ VI. Extract from the Report of the Council to the Annual
General Meeting, 19th June, 1896, giving a Brief History
of the Society.
“THE origin of the Society was mainly due to the prior issue of Sowerby’s ‘ Mineral
Conchology’ of which the first part appeared in June, 1812, and was followed by other parts
for over thirty years. The portions of this work were brought out slowly and irregularly,
and rarely illustrated more than ten species at one time. During the publication of this
contribution to Geological Science an Association was formed (probably in the year 1836)
called the ‘London Clay Club,” the members of which were enthusiastic collectors of the
shells of the Tertiary deposits in the neighbourhood of the metropolis. At one of the
meetings of the Club, about the year 1845, the late Dr. (then Mr.) J.S. Bowerbank suggested
that as the ‘Mineral Conchology’ at its then rate of issue could not possibly depict all the
British Fossils within a moderate period, it would be well to have recourse to a new method.
A proposal immediately followed that subscriptions should be solicited for a larger and more
complete publication. The idea was favorably received, Mr. Sowerby was asked to under-
take the copper-plate engraving, and many country geologists were communicated with. In
the furtherance of this project Mr. Bowerbank laboured with much zeal and energy, the
opinion being that in five-and-twenty years the whole of the British fossils would be figured
and described.
On March 23rd, 1847, a meeting was held at the apartments of the Geological Society,
Somerset House, with Sir Henry De la Beche in the Chair, when it was resolved that a
Society be constituted, the object of which should be “ to figure and describe as completely
as possible a stratigraphical series of British fossils.” The meeting further determined that
the Annual Subscription should be One Guinea, that the word “ Paleontographical ” should be
the name, and that the Society should consist of a President, Treasurer, Secretary, and a
Council of sixteen members. On that day Sir Henry De la Beche was elected President,
Mr. 8. V. Wood, Treasurer, and Mr. (afterwards Professor) Morris, Secretary. The members of
the first Council were Professor T. Bell, Mr. J. S. Bowerbank, Mr. F. E. Edwards, Sir Philip
Egerton, Dr. Hugh Falconer, Dr. W. H. Fitton, Mr. J. W. Flower, Professor Edward Forbes,
Mr. 8. B. Ibbetson, Mr. (afterwards Sir) Charles Lyell, Professor J. Phillips, Mr. (afterwards
Sir) Joseph Prestwich, Mr. D. Sharpe, Mr. James Smith, Mr. N. T. Wetherell, and Mr.
Alfred White. Of these one alone survives, viz. Sir Joseph Prestwich.*
In the May of the same year Mr. Morris sent in his resignation, and Mr. Bowerbank
was appointed his successor.
The first Annual Report was read on 23rd March, 1848, when it was stated that 640
names had been forwarded for membership, that 363 subscriptions had been received, and
that the first volume, ‘The Univalves of the Crag,’ by S. V. Wood, was ready for delivery.
This book contained the earliest list of members, and showed that 568 persons and 30 libraries
had been entered on the list at that date.
On August 14th, 1848, a Report was presented to a special meeting at Swansea (where
the British Association was assembled), in which it was mentioned that offers of Monographs
* Within four days after the reading of the Council Report, Sir Joseph Prestwich, who for some months had been in
failing health, passed away at the age of eighty-four.

had been made on the Conchiferz and Foraminifera of the Crag, the Shells of the London
Clay, the Fossil Reptilia of Great Britain, the Crustacea of the London Clay Formation, the
Corals of the Secondary Formation, the Shells of the Fresh-water Formation above the Crag,
the Tertiary Shells of the Clyde, the Spongiade of the Chalk Formation, the Fossils of the
Magnesian Limestone Formation, the Belemnites of the British Formations, the Fossil
Testacea of the Great Oolite, and the Entomostracous Animals of the Chalk, Gault, and Green-
sand Formations.
In the second Annual Report, read 23rd March, 1849, there is evidence the Society
had become established. The Local Secretaries are spoken of as being forty in number, and
the enrolled Members as many as 732. It is added that 615 persons had paid for the first
volume, and that the receipts for the year 1848-9 were (irrespective of the balance from
the previous year) £690 19s. Each succeeding year realised larger funds, until in 1867 the
maximum was reached, when the balance-sheet showed an amount of £908 5s. from
subscriptions and £1042 8s. 4d. as a total. In 1864 the late Mr. Beriah Botfield, M.P., left
a legacy of £10 10s. to the Society. A similar gift has not been repeated.
At the end of twenty years the subscriptions had produced £14,097 19s. 7d.,
and the expenditure had amounted to £13,969 17s. 3d. Twenty years later the
whole of the subscriptions showed a total of £27,385 15s. 4d., and the expenses
£27,140 17s. 6d.; whilst at the close of the forty-ninth financial year the sum of the
subscriptions was £33,459 Os. 4d., and the money expended had been £32,549 9s. 8d. It is
remarkable that so much money could have been subscribed in the forty-nine years, seeing
that the whole of the original members had, with eight exceptions, passed away. Of the latter,
four are still subscribers. At present the subscriptions from libraries are exceeding those
from private individuals, in the proportion of about twenty-four to twenty-one. This change,
so different from what had been the case in the beginning, is mainly due to the fact that of
late years strong efforts have been made to secure the accession of the free libraries.
Of the officers of the Society, the Presidents have been five,—Sir Henry De la Beche,
from 1847 to 1855; Mr. W. J. Hamilton, from 1856 to 1867; Dr. Bowerbank, from 1868
to 1876; Sir Richard Owen, from 1877 to 1892; and Professor Huxley, from 1893 to 1895.
(It is proposed that Dr. Henry Woodward be the sixth President.) The Treasurers have
been two,—Mr. S. V. Wood, from 1847 to 1884; and Mr. R. Etheridge, from 1885 to the
present time. The Secretaries have been three,—Professor Morris, for two months in 1847;
Dr. Bowerbank, from 1847 to 1862; and the Rev. Professor Wiltshire, from 1863 to the
present time.
The publications of the Society cover a large area of information, and are illustrated by
more than nineteen hundred plates. The contents consist of over fourteen thousand pages,
and define six thousand seven hundred species. The first Monograph which was issued was
that of the Univalves of the Crag. This was followed by others (generally in parts), which,
if taken in the order of publication, treat of the Reptilia of the London Clay, the Eocene
Mollusca, the Entomostraca of the Cretaceous Formations, Fossils of the Permian, the
Fossil Corals, the Mollusca of the Great Oolite, the Fossil Brachiopoda, the Radiaria of
the Tertiaries, the Cephalopoda of the Chalk, the Fossil Balanidz, the Reptilia of the
Wealden, the Tertiary Entomostraca, the Oolitic Echinodermata, the Fossil Crustacea,
the Reptilia of the Purbeck Limestones and Kimmeridge Clay, the Trilobites, the
Belemnites, the Pleistocene Mammalia, the Crag Foraminifera, the Fossil Merostomata,
the Old Red Fishes, the Crag Cetacea, the Cretaceous Echinodermata, the Mammalia of the
Mesozoic Strata, the Fossil Trigoniz, the Post-Tertiary and the Carboniferous Entomostraca,
the Carboniferous and Permian Foraminifera, the Carboniferous Ganoid Fishes, the

Lias and Inferior-Oolite Ammonites, the Sirenoid Ganoids, the Eocene Flora, the Fossil
Elephants, the Stromatoporoids, the Morphology of Stigmaria Ficoides, the Fossil Sponges,
the Inferior Oolite Gasteropoda, the Paleozoic Phyllopoda, the Cretaceous Starfishes,
and the Carbonicole.
The list of works is already large, but many years must pass away before the whole of
the British Fossils are described, and the intention of the original founders of the Society
fulfilled.”

212 FORAMINIFERA OF THE CRAG.
Characters. —Our small specimen from the Crag consists of four short, almost
equal chambers, broader than long, closely set one on another. Zoologically it is
a variety of N. radicula (Linné) ; it has many slight modifications of shape, and
is closely allied to other forms belonging to the same group.
Among the figured forms we find that figs. 9 and 10 of H. Dervieux’s pl. v
are also referred to ambigua at p. 625. Nodosaria De-Amicis, Derv., on the same
plate, figs. 63, 63 bis, though larger, papillose, and mouth-tubed, is specifically
the same.
In the numerous figures given by Soldani, rough as they are, much of interest
is shown among the many varieties of N. radicula of this sub-type ‘ ambigua.”
In the fig. L (pl. vi) referred to above, after the large ovoid primordial segment,
the four succeeding chambers are short, equal, and closely set. The fig. zz
(pl. cii) has also a large primordial segment ; the later chambers are shorter than
broad as in ambigua, but are irregular in size and direction of growth. Fig. a
(pl. cu) has very short and closely-set chambers; it is much larger than fig. L
(pl. vi), and somewhat sinuous in its line of growth. Figs. r, G, (pl. cin), also
have short close-set chambers; and fig. K combines this feature with that of
an obliquely striated Dentalina, having put on the chambers of the radicula type
in later life.
The individual, fig. 4¢ (Nodosaria radicula, parte), in pl. ii, of G. Terrigi’s
memoir in the ‘ Mem. Descr. Cart. geol. d’ Italia,’ vol. iv, part 1, 1891, is the same
as N. ambigua.
Occurrence.—This variety of N. radicula lives in the Mediterranean (Soldani),
and at 129 fathoms off the Ki Islands (‘Challenger’). It occurs fossil, with
other Nodosarizx, in several Tertiary formations.
The typical N. radicula has a wide geographical range, but it has been most
frequently recorded from high latitudes, at depths ranging from 10 to 300 fathoms.
Specimens have also been obtained from the North and South Atlantic (1360 and
2350 fathoms), from the South Pacific (37 to 1100 fathoms), from off the Cape of
Good Hope (150 fathoms), and from the Adriatic.
Its geological range extends back to the Permian of England and Germany.
It has also been met with in the Lias of England, in the Kimmeridge Clay, in the
Gault of Folkestone, in the Red Chalk of Speeton, in the Upper Chalk of Taplow,
Bucks, and of Keady Hill, Ireland; in the London Clay (Eocene) ; in the Miocene
of Italy, Vienna, and Malaga; and in the Pliocene of Italy, Garrucha (South
Spain), and St. Erth. In the Coralline Crag it has been found at Sutton; and at
Sudbourne, zone qd, ;

Characters.—Subcylindrical and tapering, varying from fusiform to club-
shaped ; longitudinally ribbed, the number and strength of the cost variable.
Three varieties from the Crag are here illustrated :
1. Pl. I, figs. 4,5; typical for such as Linné named from the figures given
by Plancus and Gualtieri; with many ribs (15—16).
2. Pl. I, figs. 22, 23; short and thick, with few ribs (9—10). This form
corresponds with fig. 86 of Silvestri’s pl. iv, Nodosaria acuticostata.
3. Pl. VI, figs. 9, 10; short, thick, and neatly compact form (about 15 to 16
ribs). Fornasini’s Nod. Bassani, ‘Mem. R. Accad. Sci. Bologna,’ ser. 5, vol. iv,
1894, pp. 205, 206, pl. i, figs. 38 —40, is near this variety, but has fewer ribs.’
Gradations and varieties of N. raphanus are shown under the name “ Dentalina
propinqua, Beissel,’’ 1891, in the ‘ Abhandl. K. Preus. Geol. Landesanst.,’ n. s.,
pt. i, p. 35, pl. vu, figs. 14—27.
Norr.—As it is almost impossible to sort all the figured specimens allied to
N. raphanus and coming within its varietal range, the foregoing synonymy must
be understood as indicating some of the best marked and most distinguishable of
the forms.
(There are also marginuline forms of the same type, which will be noticed
under Marginulina.)
Occurrence.—Nodosaria raphanus is rather common in the Mediterranean and
Adriatic at depths ranging to 1100 fathoms. The tables appended to the
‘Challenger’ report record its presence in soundings from off Culebra Island,
Danish West Indies (390 fathoms) ; and from a depth of 1375 fathoms near Juan
Fernandez. Its geological range extends from the Lias. It has also been
recorded from the Chalk of Bohemia, Westphalia, and Keady Hill, Ireland ; from
the London Clay (Hocene) ; the Miocene of Malaga, Vienna, and Muddy Creek,
Victoria; and the Pliocene of Italy. In the Coralline Crag it has been met with
at Sudbourne and Broom Hill, zone d; and at Sutton. It has also been found in
the Norwich Crag (Thorpe).
1 In F. Sellheim’s “ Beitrag ziir Foraminiferen-Kenntniss der frankischen Juraformation,”
Inaugural Dissertation, &c., Erlangen, 1893, the Dentalina, sp. aif. lamellosa, Torq., page 12 (of sep.
copy), pl. o, fig. 3, seems near enough for Nodosaria raphanus ; and N. duodecim-costata, fig. 2, is
not far removed ; fig. 4 might be VV. raphanistrum.

Characters.—This, when in good condition, is the longest, straightest, and
most symmetrical of the costate Nodosariz. Shorter forms approach, and indeed
pass into NV. raphanus, becoming broader in some parts of the shell than in others.
Many individuals commenced growth with a large primordial segment (megalo-
spheric or form ‘‘ A”’—see above, p. 90); and others with a small beginning
(microspheric, or form ‘ B’’) have the shell tapering backwards or downwards to
a point. ‘These features, as well as irregularities of growth, have influenced the
giving of names to a great extent. When the shell has grown with a curvature it
becomes a Dentalina; when the excentricity brings the stolon more to one side
than the other, the form becomes a Vaginulina or Marginulina, and when
extreme leads to Cristellaria.'
Gradational varieties of N. raphanistrwm are well shown under the name
** Dentalina acuta, @’Orb.,” and “ D. polyphragma, Reuss,” in ‘ Abhandl. K. Preuss.
Geol. Landesanst.,’ n. s., part ii, 1891, pp. 87, 38, pl. vii, figs. 28—65.
Occwrrence.—Nodosaria raphanistrwm is of very rare occurrence in recent seas.
It has been found in the Mediterranean and Adriatic. Fossil specimens have
been recorded from the Lias of Yorkshire and elsewhere, the Oxford and
Kimmeridge Clays ; and there are corresponding forms, such as Nod. Zippei, &c., in
the Chalk of England, Westphalia, and Bohemia. N. raphanistrum is also known
in the Hocene (London Clay and Thanet Sands’) ; the Miocene of Vienna, Italy,
Malaga, Malta, and San Domingo ; also in the Pliocene of Italy, and of Auckland,
New Zealand. In the Coralline Crag it has been found at Sutton only.
1 This subject has often been treated of; for instance, in the ‘Monthly Microsc. Journ.,’
vol. xv, 1876, p. 76.
* Mentioned in the ‘Mem. Geol. Survey Gt. Brit.,’ vol. iv, 1872, p. 575, but it is doubtful.
The allocation of this species, together with a Planorbulina and a Polymorphina, to the Woolwich
and Reading beds, at p. 578, is a mistake.

These two small Nodosarians from the Crag, bilocular and ribbed, having the
suture well marked and a projecting mouth-piece, are nearly matched with either
the small young or arrested forms of Nodosaria longicauda, d’Orb., in Silvestri’s
memoir referred to above, p. 58, pl. v, figs. 107, 105, and 118, and var., pl. vi,
fies. 133, 134, or, with the small forms, figs. 1388—147, which he has named N.
provima, p. 63. The latter are the nearest to ours, inasmuch as the second
segment is smaller and more tapering than the first. The latter feature, namely,
the delicate lagenoid second chamber, is emphasised in N. pupoides, Silv., p. 65,
pl. vi, figs. 148—-158. Indeed, all the three so-called “‘species” (longicauda, proxima,
1 In the list of synonyms at pp. 52, 53, the names Nodosaria inflata, Reuss, Dentalina inflata,
Reuss, and Nodosaria nana, Reuss, should not have been inserted as belonging to the real WV. scalaris.

and pupoides) are essentially the same, differing but slightly in contour and style
of growth. Of the three, the little specimens from the Crag best agree with the
proxima form.
Pl. vu, fig. 15 (Gedgrave), has the sutures shallower and the riblets smaller
than pl. iv, fig. 8 (Bridlington). Brady’s figure of N. provima has the two
chambers nearly equal in size, with a deep suture, and he was somewhat inclined
to refer it to NV. scalaris (Batsch). The number of ribs varied in the specimens
collected by the ‘ Challenger.’
Some bilocular costate Lagene (simulating N. provima) have been figured by
Parker and Jones, Wallich, O. Rymer Jones, &c.; they have the second or super-
added chamber larger than the first, corresponding in some degree to the beginning
of microspheric Nodosariz.
Throughout the series from the Crag there is considerable variation in both the
depth of suture and number of riblets.
Occurrence.—Nodosaria prowvma im recent seas appears to be confined to
tropical and subtropical latitudes. Specimens were obtained by the ‘ Chailenger’
from off the Azores (450 fathoms); off Tristan d’Acunha (100 to 150 fathoms),
of Raine Island, Torres Strait (155 fathoms) ; off the Phillipines (95 fathoms),
and off the coral reef of Honolulu (40 fathoms). The shell figured in ‘ Phil.
Trans.,’ vol. cly, 1865, pl. xvi, fig. 2, from the North Atlantic, nnder the name of
N. scalaris, is probably referrible to this species.
Fossil specimens have been obtained from the Phocene of San Quirico, near
Sienna (Silvestri), and of Ponticello, near Bologna (Fornasini). We have in our
own collections numerous specimens from the Miocene of Muddy Creek, and from
the Casterlian and Scaldisian of Antwerp. In the Coralline Crag it occurs in
nearly every zone examined.
Genus’ 3.—Dentatina, d’Orbigny, 1826.
Part 1, 1866, p. 53.
This subgeneric (or, indeed, only quasi-subgeneric) form of Nodosaria has
been so often referred to by writers on Foraminifera, both separately and under
the name of Nodosaria, that it appears to be useless to endeavour to disentangle
the reference further than as suggested at page 53 of Part I. So that besides
indicating Nodosarima as having been used as a comprehensive generic term by
Parker, Jones, Goés, and a few other authors, we need only add to each of the
lists there given, under ‘*‘ Nodosaria ”’ and “ Dentalina,” the words ‘‘and others.”
1 Quasi-generic only.
DENTALINA OBLIQUA. 221
To do away with the term ‘ Dentalina’”’ would be very inconvenient, and,
indeed, an unnecessary sacrifice to an attempted exactness in terminology; for its
use is certainly convenient in the frequent mention and defining of the arcuate
and tapering Nodosarians to which it bas been so long applied, whether by itself,
or inserted in brackets after ‘** Nodosaria.”’

Characters.—This is an elongate, acuminate, and arcuate modification of
Nodosaria raphanus, and to avoid repetitive terminology the word Nodosaria is
here omitted before Dentalina, as intimated above at pages 206 and 220.
This is not the smooth D. obliqua of d’Orbigny; see ‘Ann. Mag. Nat. Hist.,’
18/1, pz 159.
The slender, acuminate, and straight (microspheric) form of N. raphanus
(N. aciculata of Lamarck) is beautifully illustrated by Silvestri (‘ Atti Accad.
Gicenia Sci. Nat.,’ ser. 3, vol. vii, 1872, p. 39, pl. il, figs. 52—56) as Nodosaria
conica (thus named by him after Soldani, but not by the latter, for Soldani named
nothing according to the Linnzean method).’
Occurrence.—Dentalina obliqua has a wide geographical and bathymetrical range.
The tables appended to the ‘ Challenger’ Report record the occurrence of specimens
at six stations, namely, off the north-west coast of Ireland, off the west coast of
Africa, off the Cape of Good Hope, between Prince Edward Island and Kerguelen, off
Sydney, and in the equatorial region of the South Pacific. The depth in these cases
ranged from 150 to 2425 fathoms. It occurs also in the Mediterranean and Adriatic.
Fossil specimens have been recorded from the Permian (D. Kingii), from the Lower
Lias (Brady), from the Chalk of Bohemia and of Swanscombe (Kent), from the
London Clay (Hocene), the Oligocene of Hlsass, the Miocene of Italy, Messina
(Sicily), and Muddy Creek (Victoria), from the Pliocene of Italy, and of Garrucha,
South Spain. Inaddition to the record from Sutton given in the First Part of this
Monograph, we have specimens from Sutton, zone f, and from Aldborough, zone g.

Occurrence.—Dentalina obliquestriata, as stated in the First Part of this
Monograph, appears not to have been found in a recent condition. No mention
of it is made by Brady in the ‘Challenger’ Report. It has been recorded from
the Yorkshire Lias (Tate and Blake); from the London Clay (Sherborn and

In the First Part of this Monograph, d’Orbigny’s Dentalina pauperata was
taken as a subtypical form to which certain Dentalines might be conveniently
referred. 'lheir relationship one to another, and to D. communis, d’Orb., was
carefully indicated in the nomenclatorial lists at pages 52—62. Names upon

variable shell; and it scarcely appears worth while to enlarge the synonymy.
Many plates in the works of d’Orbigny, Reuss, Schlicht, Terquem, Neugeboren,
Goés, Dervieux, Egger, Beissel, and others, contain legions of named specimens
showing modifications of this simple type.

in nearly all seas, and at all depths from the shore-line down to 2740 fathoms. It
is worthy of note that the distribution tables appended to the ‘Challenger’
Report record no specimens from the North Pacific.
The shell has been found in a fossil condition in the Carboniferous and
Permian Limestones; in the Yorkshire Lias; in the Cretaceous formations
generally ; in the London Clay (Eocene); in the Miocene of Vienna, Italy, and
Malaga ; in the Pliocene of Garrucha (South Spain), Italy, and Kar Nicobar ; and
in Pleistocene deposits generally.
The tables appended to the ‘ Challenger’ Report show a rather restricted
geographical range for Dentalina pauperata. The records of its occurrence are
almost entirely from high latitudes, and from depths ranging from 138 to 245
fathoms. Its earliest recorded occurrence in a fossil condition is from the Lias
(Terquem). It has also been found in the Gault of Folkestone ; the Upper Chalk
of Taplow, Bucks, and Keady Hill, Ireland; the London Clay (Eocene); the
Miocene of Piedmont, Vienna, and Muddy Creek, Victoria; and the Pliocene of
Piedmont and St. Erth. In the Coralline Crag it has been found at Sutton only.

ibid., p. 92, pl. xevii, fig. bb. As Soldani did not use the Linnean method of nomenclature, the
straight-sutured Dentalina is really “ D. farcimen of Reuss.’ Further, Soldani applied the term
“‘farcimen’’ to more than one of his figured specimens (see ‘ Annals Mag. Nat. Hist.,’ ser. 4, vol. viii,
1871, p. 154, No. 2; and p. 159, No. 20; also ibid., p. 153): if individual names were taken for
species from his books (and there they seem sometimes to have been used as much generically a
otherwise) much confusion would arise in the alteration of numerous trivial names.
VAGINULINA LAVIGATA. 227
General Characters.—Vaginulina igs an elongate, more or less compressed
or complanate Nodosarine, with eccentric (marginal) aperture and _ oblique
chambers ; straight or curved; septate or compact; smooth, limbate, or costate.
Linné adopted the figures published by Plancus, Gualtieri, and Ledermiiller for
his Nautilus legumen.' The figure given by Gualtieri is decidedly limbate ; but
those by Plancus and Ledermiiller, although apparently limbate, may be smooth
(as regarded by Signor Fornasini), with the septa marked only by a difference in
the shell-structure, as more clearly shown in Brady’s figures in the ‘ Challenger’
Report. Doubtless both the limbate and the smooth forms come together under
the same species zoologically, but their readily distinguished features make it
convenient to retain distinct names for them. ‘l'heir relationship was indicated in
the tabular list at pages 64—66 in Part I; the smooth forms being variety a, var.
6, and var. »; the limbate forms (V. legumen proper) being comprised in varieties
RauOsnes, Gy 05. bs, KC.
The trivial circumstance of the quasi-smooth figure given by Plancus being
the first mentioned by Linné in his references (possibly because his was the oldest
book) does not keep us from accepting the limbate form (Gualtieri’s) as this best
medium type (according to the plan followed by Parker and Jones), around which
the weak and smooth (V. levigata, &c.) on one hand, and the more ornamented
forms (V. linearis, &c.) on the other, are taken as noticeable varieties; asin the
classificatory lists above referred to.
This species (including the forms figured by Plancus and Gaultieri) is referred
to by Parker and Jones in the ‘ Annals Mag. Nat. Hist.,’ ser. 3, vol. ii, 1859,
p. 479. See also C. Fornasini’s remarks on the limbate form in the ‘ Bollet. Soc.
Geol. Ital.,’ vol. v, pp. 25—30, with woodcut copies of the early figures published
by Plancus, Gaultieri, and Ledermiiller.

VAGINULINA LINARIS. 229
VAGINULINA LEGUMEN, Hager, 1895. Jahresb. Nat. Ver. Passau, vol. xvi, p. 24,
pl. ii, figs. 4a, b, 8.
Characters.—Straight or curved ; chambers more or less compact, smooth. The
Bridlington specimen (PI. IV, fig. 9) is retained here for comparison with the Crag
specimen (Pl. V, fig. 8). The former (megalospheric) is straight, compressed, and
Symmetrical; the latter (microspheric ?) is curved and tapering; it is of irregular
growth in the later chambers, which are not uniform or compact.
Occurrence.—This, together with the limbate and costate forms, is widely dis-
tributed in shallow and deep seas. It occurs fossil, with other Nodosarvine, in the
Lias, and many later formations of Secondary, Tertiary, and Post-Tertiary ages.

of longitudinal costule is variable in expression and extent, frequently not
affecting the youngest chambers, and sometimes limited to the earliest, and
partially affecting the tops of the other chambers near to or just below the
junction with the next segment. This kind of ornament is present in several

Note. — Vaginulina striata, d’Orb., after Soldani, is much compressed,
symmetrically tapering, longitudinally costulate, compact, and rigid in its style of
growth ; and was taken as the type of V. lequmen, var. 0 (Part I, p. 66). As this
form has been included by some in Vag. linearis, its synonymy is here appended.

Occurrence.— Vaginulina linearis is a shallow-water form, rather commonly met
with off the British coasts, and apparently most at home in the waters of the
North Temperate Zone. Specimens were obtained by the ‘Challenger’ from
three stations :—Off Bermuda (435 fathoms), off Culebra Island (390 fathoms),
and south-east of Pernambuco (350 fathoms). In a fossil condition it has been
found in the London Clay (Hocene); Tertiary of Upper Silesia; the Miocene of
Italy, and Muddy Creek (Victoria) ; and in the Pliocene of Italy.
So far as the Crag is concerned, we have nothing to add to the record from
Sutton in the First Part of the Monograph.

VAGINULINA OBLIQUESTRIATA. 231
3. VAGINULINA OBLIQUESTRIATA, sp. nov. Plate V, figs. 9, 10, 11.
Characters.—This Vaginulina is stout, subcylindrical, varying from straight to
arcuate: fig. 11 is the straightest ; fig. 9 has a gentle curve; and fig. 10 tapers
and bends like a Dentalina. 'The chambers are closely set, marked off by very
slightly oblique septa. The surface-ornament consists of rather strong, oblique,
longitudinal costulee, either extending the whole length of the shell (fig. 9), or
interrupted at the sutures (figs. 10 and 11). These riblets are most oblique in
fig. 10, less so in fig. 9, and are almost straight in fig, 11.
Although compact and ribbed this form is not so much compressed as the flat
V. striata, d’ Orb. (after Soldani), which is the type of var. 6 at page 66 of Part I,
and it seems to require a distinct name.
A somewhat similar, but much stronger ornament is observable in the
Dentalina divergens, Reuss, 1864 (‘ Sitz. k. Akad. Wiss. Wien,’ vol. 1, p. 456, pl. iv,
fie. 10), with its strong oblique interrupted costule.
Of the various published Vaginuline related to V. linearis the follgnatts have
oblique strie.

Very numerous specimens of small Cristellarian and Marginuline passage-
forms have been abundantly figured in various plates by d’Orbigny, Reuss, Schlicht,
Terquem, Goés, and others. To collate and co-ordinate these exactly would be
almost impossible. The foregoing synonomy, and that given by Signor G. A.
De Amicis in the ‘ Bolletino Soc. Geol. Italiana,’ vol. xii, fase. 3, 1893, pp. 107,
108, will assist the student in this matter.
MARGINULINA COSTATA. 235
Characters.—A short, curved, partially spiral Nodosarine ; with smooth, more
or less inflated chambers, not numerous, and enlarging rapidly in process of growth.
This little shell, which is very variable in its contours, feebly represents the far
more compact and symmetrical Cristellariz.
Occurrence.—Marginulina glabra has a wide geographical distribution, but appa-
rently has not been met with in high latitudes. Specimens have been taken from
depths ranging from 15 to 2740 fathoms. The geological range of the species is
extensive. Specimens have been found in the Lias of England and the Continent ;
in the Cretaceous formations generally, both English and foreign; in the London
Clay (Eocene), in the Oligocene of Germany, in the Miocene of Italy and Vienna ;
and in the Pliocene of Piedmont and Garrucha (South Spain). So far as the Crag
is concerned, we have nothing to add to the record in Part I of the Monograph.

‘ Soldani suggests that some of the specimens figured as “M,N, &e.,” [m—z?] in plate xciv
might be such as with Linneus would be termed “ Raphani, Raphanistri, et Rapistri.’ Soldani
thinks that figs. p, @,and even y may be varieties of his “ Orthoceras Corniculum.” The nominal
references in ‘Ann. Mag. Nat. Hist.,’ September, 1871, p. 163, and in the ‘ Challenger’ Report,
p. 528, for ‘‘N, P, Q, B, X, Y,” are not quite correct. M, N, BR, and v belong to Nodosaria

Characters ——This Nodosarine is essentially a Nodosaria having an eccentric
growth, which gives either an oblique or partially spiral style of growth to the
early chambers, and a marginal aperture (with or without a short neck) to the
older and the last segments. It varies in cross-section from subcylindrical to oval
and compressed. ‘The chambers are moderately compact; more or less septate,
and therefore varying in relative fulness; and are marked with longitudinal
riblets, as in Nodosaria raphanus, of which, indeed, this is essentially only a
Marginuline modification.
Occurrence.—Marginulina costata seems to be most at home in the North and
South Atlantic, the Mediterranean, and the Adriatic (870—1240 fathoms) ; but

inferior specimens have been met with in British waters and off the coast of New
Zealand. Its geological range extends to the Lias of England, Ireland, and
France (Brady). It has also been found in the Kimeridge Clay (Brady) ; in the
Cretaceous of Ireland (Wright); in the Eocene (London Clay); and in the
Miocene of Italy, Malaga, Vienna, and Muddy Creek. In addition to the record
from Sutton in the First Part of the Monograph, we have found one specimen at
Broom Hill, zone d.

CRISTELLARIA CULTRATA. 239
General Characters.—See also Part I, p. 72. Test planospiral in part or
entirely ; discoidal, complanate, lenticular (biconvex), crozier-shaped or ensiform ;
chambers subtriangular, sickle-shaped or of other hook-like form, mostly. compact ;
smooth, limbate, granulose, or longitudinally costulate.
The smooth lenticular Cristellaria without a keel is C. votulata (Lamarck) ;
with a keel C. cultrata (Montfort) ; with broad, dentate keel, C. calcar (Linné) ;
and when much compressed, broadly keeled, and ornamented, it is C. cassis
(Fichtel and Moll). Parker and Jones adopted (. calcar as the best central and
representative type of Cristellaria. OC. cultrata and rotulata are inferior to it in
point of development, whilst C. cassis surpasses it in the augmentation and diversity
of ornamental and marginal growths.
As these forms are very variable in the several features and graduate one into
the other, their separation into quasi-species is quite of an artificial character; and
itis often difficult to determine to which group some individuals should be allocated.
In the following synonymy only the best marked figured specimens have been noted.
(. cultrata, being present in the Crag, is here described.

1 G. Bianchi states, at p. 18, that the majority of these have a broad pellucid margin around the
shell; therefore they are the same as C. cultrata. In the 1760 edition there are added to the plate
figs. xii, 8, T, V, and xiii, Zz, which appear to be true cultrata. The fig. 3 quoted above appears to
belong to the minority, namely, those without the broad pellucid margin, and is therefore rotulata ;
and this notwithstanding the remark at p. 13, that the artist has not (but might have) shown the
marginal flange. See also Fornasini, ‘ Boll. Soc. Geol. Ital., vol. vi, 1887, p. 38. |
? In these posthumous papers of Count Giuseppe Ginanni, of Ravenna, fig. 113 is evidently a
bad drawing of Cristellaria cultrata ; and, as is the case also with figs. 112 and 114, it has an
irrelevant description taken wrongly from Planecus. Fig. 111 is one face, and fig. 112 probably the
other of Rotalia Beccarii; and fig. 114 is possibly a poor Crist. cassis.

Nots.—The synonymy of Cristellaria cultrata and its very numerous allies is
dealt with in the ‘‘ Remarks on the Foraminifera with especial reference to their
Variability of Form, illustrated by the Cristellarians,”’ by Prof. T. Rupert Jones, in
the ‘Monthly Microsc. Journ.,’ vol. xv, 1876, pp. 61—92, and pp. 20, 201. At
pp. 77—84 the synonymy of the varietal modifications of Cristellaria calcar,
whether keelless or keeled, rowelled, outspread, trihedral, or elongate, is detailed,
as indicated by published forms, from 1735 to 1846. The second part (by T. R.
Jones and C. D. Sherborn) of the same memoir appeared in the ‘ Journ. Roy.
Microsc. Society,’ vol. for 1887, part 2, pp. 545—557. The selection for the
synonymy is chiefly guided by the absence of ornament and of any peculiarity in
the shape of the chambers, and doubtless is merely an artificial arrangement of
the forms lying between C. rotulata and C. cassis.
Characters.—Shell lenticular, nautiloid, smooth, consisting of one or more
spiral whorls of subtriangular or falciform chambers, the outermost embracing
the inner whorls. Septal sutures variable in expression; sometimes sunken,
often limbate. Umbones sometimes much thickened. Margin keeled; carina
narrow or wide. Aperture round or angular.
Diameter of specimens from the Crag about one-twentieth of an inch (13 mm.) ;
but some from other sources attain very much larger dimensions.
Occurrence.—Cristellaria cultrata is found in various fossiliferous strata, com-
CRISTELLARIA GIBBA. 247
mencing with the Silurian ;' it is represented in the Lias and Oolite, and abounds
in the Gault, Chalk-marl, and Chalk. Together with cognate forms or varieties,
it is plentiful in many Tertiary deposits at home and abroad. Recent specimens
are not very common, but have been found in Arctic, Atlantic, and North-Pacific
dredgings at considerable depths, and in the Mediterranean and Adriatic Seas.
In the Crag it is very rare, one or two smallish specimens from Sutton, and
Thorpe, near Norwich, in Mr. Wood’s Collection, being the only reliable examples
we have seen.
Together with its ally, OC. rotulata, this Cristeilaria is widely diffused in seas
and oceans, as far north as the Arctic Circle on the coast of Norway, and down
south on the shores of Patagonia. Fine specimens are rarely found at less
depth than 100 fathoms. . cultrata was collected by the ‘Challenger’ in the
North Atlantic at from 390 to 2435 fathoms; in the South Atlantic at 350 and
675 fathoms; in the South Pacific from 38 to 275 fathoms; and in the North
Pacific at 95 fathoms. It lives also in the Mediterranean and Adriatic. Small
specimens with narrow keel occur in shallow water in the British seas.

C. crepidula. It has many congeners, varying in relative thickness and other
unimportant features.
Occurrence.—In the North Atlantic and South Pacific at less than 500 fathoms,
but it is credited with a much wider area for its habitats. Under various names
it may be recognised in descriptions of fossil Cristellariz from both Mesozoic and
Cainozoic deposits. We have it from the Crag at Sutton, zone f.
It has been found fossil in the Neocomian (Bargate beds) ; Cretaceous (Red
Chalk) ; Oligocene of Elsass ; and the Miocene and Pliocene of Italy.

A memoir on the tubulose Polymorphinx, of which there are sixty-nine known forms, has lately
been communicated to the Linnean Society by T. R. Jones and F. Chapman. They define five groups,
namely: (1) with “apical” growths (divisible into five sub-groups,—forme damxcornis, coronula,
acuplacenta, horrida, et racemosa) ; (2) “subapical”? growths (forma circularis); (3) “on general
surtace”’ (forma diffusa) ; (4) “marginal” (forma marginalis) ; (5) “ mixed kinds of growths ” (forma
complicata).

Characters.—Shell (typical) ovate, gibbous, slightly asymmetrical; anterior
extremity acute; posterior obtuse, rounded. Chambers few, oblong, oblique,
somewhat inflated.
The shell of P. Jactea has normally four or five visible chambers, sufficiently
ventricose to disturb the regularity of the general outline; the sutural lines marked
by shght depression. In its typical form the transverse section is nearly circular ;
but this is a variable character, and the compressed modifications described by

POLYMORPHINA GIBBA. 253
Prof. Reuss under the name of Globulina amygdaloides may be taken as repre-
senting a subvarietal condition.
Occurrence.—Polymorphina lactea is a cosmopolitan species, and has a wide
bathymetrical range, although it is most at home in the comparatively shallow
waters of temperate latitudes. Specimens obtained from great depths are rare and
poorly developed. The geological range of the species extends to the Kimeridge
Clay and the Portland Limestone of Dorsetshire (Parker and Jones). Polymorphina
lactea has been found by Mr. Charles Moore in a Jurassic marly limestone from
Queensland, Australia (‘ Quart. Journ. Geol. Soc.,’ vol. xxvii, pp. 236, 239). It
has also been found in the Cretaceous of Bohemia and Russia, in the Gault of
Folkestone, and in the Red Chalk of Speeton; in the Lower and Middle Tertiaries
of Northern and Central Germany; in the Miocene of Piedmont and of Muddy
Creek, Victoria; and in the Phocene of St. Erth.
We have specimens in our own collections from the Casterlian and Scaldisian
of Antwerp ; and it is found commonly in Pleistocene deposits. In the Coralline
Crag we have met with it in every zone examined. It has also been found in the
Red Crag of Essex, in the fluvio-marine beds of Southwold and Thorpe, and in
the Chillesford beds.

Characters.—Shell (typical) subspherical or oval, somewhat produced at the
apex, broad and rounded at the base. Chambers few, compact, and overlapping.
Sutures marked, not depressed.
Polymorphina gibba is perhaps as definite in typical characters, and as apt for
technical description as any member of the group; still some latitude must be
allowed in the terms employed for its diagnosis. D’Orbigny’s ‘ Modele,’ No. 63,
represents a nearly globular shell, and may be taken as representing the normal
form. Our list of synonyms refers to specimens deviating in no striking particular
from this standard.
The shape of the anterior portion of the shell differs considerably in different
individuals. In some it is acuminate, and the orifice is situate in a mammillate
protuberance ; in others it is truncate, and the general aperture is flush with the
body of the shell. In rare examples the orifice is turned inwards, like that of an
Entosolenian Lagena.
A compressed variety sometimes occurs bearing a similar relation to P. gibba
that P. lactea, var. amygdaloides, does to P. lactea; and of this d’Orbigny’s
Globulina xqualis is perhaps the best representative: its synonymy will be found
in the Monograph of the genus, op. cit., pp. 216, 217.
The leading features of the tubulose forms of the Polymorphine shown by
figs. 70—75 in Plate I indicate P. gibba as one of their types. Fig. 71 leans
towards P. lactea ; and fig. 74 has a tendency to protrude one of its chambers,
hke P. problema, but not enough. As for the style of the outgrowths, fig. 70 has
them complicated,—that is, both apical and subapical ; fig. 71 seems to have had a
flat apical mass giving off lateral branches,—acuplacental ; figs. 72, 74, 75 had a
very free-growing, branching (racemose), apical outgrowth ; and fig. 73 had an
extraneous growth both on the apex and general surface (diffuse); fig. 76 is
evidently the exposed base of a racemose, or possibly of a placental (cake-like)
growth.
256 FORAMINIFERA OF THE CRAG.
Occurrence.—The geographical range of Polymorphina gibba is co-extensive
with that of P. lactea. It has also a very extended geological range. It has
been obtained from the Kimeridge Clay of England, and from the Cretaceous of
Europe generally ; and it is a common Tertiary Foraminifer, as will be seen by
reference to the Table of Distribution in the Appendix. In the Pliocene it is
recorded from the Diestian, Casterlian, and Scaldisian of Antwerp, from Italy,
Garrucha, and St. Erth. In the Coralline Crag we have found it in nearly every
zone examined.

|
Characters.—Shell ovate-elongate, symmetrical, pyriform; anterior portion
tapering, acuminate; posterior obtuse, rounded; margin entire, septal lines not
depressed. Chambers elongate, closely embracing, arranged triserially.
Polymorphina gutta, in good specimens, presents tolerably definite characters,
its triserial arrangement, closely embracing chambers, and circular transverse
section being sufficient for ordinary diagnosis. Its long, tapering upper extremity
and numerous chambers distinguish it from P. gibba, and the rounded base and
compact spiral build from its nearest ally, Polymorphina (Pyrulina) acwminata,
d’Orb.
Occurrence.—Polymorphina gutta has not hitherto been recorded in the recent
condition. It is best known as a Tertiary fossil, but has been found in the Hils
Clay (Neocomian) of Germany, in the English (Bargate) Beds of similar age, and
in the Gault of Folkestone. Specimens have been recorded from the Hocene
(London Clay and Barton Beds), from the Oligocene of Pietzpuhl, and from the
Upper Tertiaries of North Italy.
We have nothing to add to the record given in the six columns of the Table,
and Appendix II, Part 1, 1866, so far as the occurrence in the Crag is concerned.’

Characters.—More or less oviform and compressed, sometimes subfusiform ;
suboval in transverse section ; broad about the middle, rounded below, obtusely
pointed above. Five or six chambers, variable in size, irregularly subspiral. This
form is nearly allied to the typical P. communis.
Oceurrence.—Polymorphina sororia is stated in the ‘ Challenger’ Report
to have been found at two stations in the North Atlantic, west of Ireland,
at depths of 808 and 1443 fathoms ; also midway between Cape of Good Hope and
Kerguelen Island (1375 fathoms). It was also found by the ‘ Gazelle’ off Sierra
Leone, at a depth of 367 fathoms (Egger).
As a fossil it has been recorded from the Chalk of Taplow ; from the Oligocene
of Hlsass and Pietzpuhl; and from the Pliocene of Belgium and St. Erth. The
Crag specimens were obtained from Broom Hill (zone d) and Aldborough (zone g).

Note.—D’Orbigny’s name ‘‘ compressa”’ has been generally adopted, because
the possibly similar form “ twberosa
99
is based on a bad figure.
Characters.—Shell oblong, inequilateral, compressed, more or less fusiform.
Chambers numerous, arranged in two unequal series, somewhat inflated. Septal
lines depressed. Surface smooth. Aperture variable, usually simple, circular,
and coronate, sometimes labyrinthic or porous.
POLYMORPHINA THOUINI. 261
A somewhat indefinite biserial arrangement, in which the segments appear
irregularly opposed to each other rather than in alternation, together with the
rounded margins and constricted septa, are characters sufficient for general
diagnosis. The difficulty in distinguishing attenuated specimens from those of
P. cylindroides is confessedly great ; but the less compressed contour of the latter,
its few chambers, and their erect position, will usually serve the purposes of the
systematist.
A specimen of irregular growth is shown by fig. 26, Pl. V. It is so much
encrusted with carbonate of lime that it presents a false resemblance to P. variata.
Occurrence.—Polymorphina compressa has a wide range, but is most common in
the comparatively shallow waters of temperate latitudes. It has been found as
far north as Smith Sound and Novaya Zemlya; also in the tropical South
Atlantic and the North and South Pacific. It mostly affects shallow water, but
specimens have been found at depths of from 400 to 600 fathoms.
In the fossil condition P. compressa has been recorded from the Lower and
Middle Lias of the north part of France, and from the Middle and Upper Lias of
Somerset. It has been found also in the Lower Oolite of Somerset; in the Oxford
and Kimeridge Clays; in the Cretaceous of England, France, Germany, and
North America. We have not observed any records from Hocene deposits; but
it has been recorded from the Oligocene of Germany, from the Miocene of
Vienna and Muddy Creek (Victoria), from the Pliocene of Belgium and St. Erth,
and from the Pleistocene of Norway and the West of Scotland. In the Crag we
have met with it in every zone examined.

Characters.—Shell attenuate, subcylindrical, slightly constricted at the septal
lines. Anterior extremity acute; posterior rounded. Chambers elongate,
oblique, erect, slightly ventricose.
Of the very long, many-chambered Polymorphinw, perhaps P. Thouini is the
best-defined variety; yet the name does not appear to have been generally
adopted by authors. It represents a longer, more cylindrical subtype than
P. fusiformis, with a larger number of chambers and less oblique setting-on ;
indeed, it resembles more a much outdrawn specimen of P. problema than any
other variety.
Occurrence.—Polymorphina. Thouini is of rare occurrence in recent waters.
The records given in the ‘ Challenger’ Report are from the Levant (90 fathoms),
and off Hast Moncceur Island, Bass Strait (38 fathoms). In a fossil condition the
species is also somewhat rare. It has been obtained from the Lias (Terquem) ;
from the Kocene (Calcaire-grossier) of the Paris Basin; from the Oligocene of
Pietzpuhl; and from the Pliocene of Italy. In addition to the record for the
Coralline Crag, given in Appendix II, Part I, we have specimens from Sudbourne
Hall, zone d, and Broom Hill, zones d and e.

Occurrence.—Polymorphina nodosaria, so far as is at present known, does not
occur in recent seas. Fossil specimens have been obtained only from Tertiary
deposits, namely the Middle Tertiaries of Central Germany and Hungary ; and
the Phocene of Antwerp and St. Erth. In the Coralline Crag it has been met
with only at Sutton.

Characters.—Shell elongate, fusiform, more or less compressed ; acuminate or
subacuminate at the ends. Chambers elongate, in two parallel series, with
slightly depressed sutures.
Occurrence.—Polymorphina cylindroides is not recorded in the ‘ Challenger’
Report, nor in Egger’s report on the voyage of the ‘Gazelle.’ It has been
dredged off Skye by Mr. Barlee; also in some other northern localities.
The type-specimens were obtained by Count Miinster from the Newer
Tertiaries of North Germany. It has been figured by von Schlicht from the
Oligocene of Pietzpuhl.
In the Crag we have specimens from Broom Hill, zone e, and Gedgrave,

Occurrence.—Polymorphina concava is very rare in the recent condition.
Williamson’s specimens were obtained from Brixham, and we are not aware that
it has been met with elsewhere than off our own coasts. A fossil specimen has
been found in the Neocomian (Bargate beds) of Surrey. It has not been recorded
from any of the Tertiary formations older than the Pliocene. Mr. Millett has
found it in the St. Erth beds; and we have it from the Casterlian of the Katten-
dyke Docks, Antwerp. Mr. Millett has it from the Post-glacial beds of March,
Cambridgeshire, and from the ‘Challenger’ dredgings of Station 185, Raine
Island, at 155 fathoms. The figured specimen is from the Coralline Crag at
Gomer ; we have specimens from Gedgrave, zone f.

POLYMORPHINA PROBLEMA. 267
Occurrence.—Polymorphina communis (including P. problema) is essentially a
shallow-water form, the greatest depth at which it has been observed being 155
fathoms (Brady). Its geographical range is almost world-wide.
As a fossil it has been found in the Lower Lias; the Neocomian (Bargate
beds of Surrey); the Gault of Folkestone; the Red Chalk; the Oligocene of
Elsass and Pietzpuhl, the Miocene of Vienna and Muddy Creek (Victoria); the
Pliocene of Antwerp, Garrucha (Spain), and St. Erth. In the Coralline Crag we
have specimens from every zone examined.

D’Orbigny’s Modéle No. 61 forms a convenient subtype, embracing a large
group of Polymorphine, which have in common a somewhat acervuline mode of
growth, and but little adhesion or overlap amongst the segments. His later
figures of the same species are by no means so characteristic, and are scarcely
separable from P. communis; of which, indeed, we consider P. problema to be a
wild-growing modification.
Occurrence.—For the occurrence of this Polymorphina, which is intimately
allied to P. communis, see the notes on the latter at page 267.

I Abtheil., p. 487, No. 10. (After
Schlicht’s figures.)
_Characters.—Shell subrotund, rounded-oblong in outline, being nearly equally
rounded at the ends, with almost straight parallel sides. Both in vertical and
transverse section it is compressed and bluntly oval (shortest in the latter) ;
chambers four (?), oblique, gibbose, and closely set with indistinct septal lines.
Reuss’s fig. 66 in pl. vi (1855), closely resembles this compact Polymorphina,
except in being more oval. Fig. 9 in Schlicht’s pl. xxvii, and fig. 2 in pl. xxix,
are more circular in transverse section, but otherwise express the subrotund form
of our specimen. Taken altogether, the Polymorphina under notice is certainly
within the probable range of variation of P. turgida, Reuss.
P. (globulina) globosa, von Minster, described and figured by F. A. Romer in
the ‘ Neues Jahrbuch,’ &c., 1838, p. 386, pl. in, fig. 338, evidently belongs to the
same group as the above. It is ‘‘nearly round, smooth, with scarcely dis-
tinguishable chambers,”’ and is slightly compressed.
P. rotundata, Bornemann (1855, ‘ Zeitsch. Deutsch. Geol. Ges.,’ vol. vii, p. 346,
pl. xviii, fig. 3, copied in the ‘Trans. Linn. Soc.,’ vol. xxvu, p. 234, woodcuts,
figs. k, 1, m), is a long-oval form, closely allied to the foregoing.
An obovate variety is recognised in the ‘ Challenger’ Report, p. 570, pl. lxxiii,
figs. 5—8. Other varieties are shown by Dr. A. Goés, ‘K. Svensk. Akad.
Handl.,’ vol. xxv, No. 9, p. 57, pl. ix, figs. 529—534.
Polymorphina solidula, Terquem, ‘ Mém. Soc. Géol. France,’ ser. 3, vol. i,
Mém. 3, 1878, p. 40, pl. ii (vii), figs. 31 a, b, is another member of the same
group of compact, subrotund, compressed forms.
Occurrence.—P. turgida comes from the Oligocene Septaria-clays of Germany,
and P. globosa also from the younger Tertiaries of Northern Germany. The
figured specimen (Pl. V, fig. 25), from the Crag of Sutton, is in the British
Museum.
P. rotundata, mentioned above as a closely allied form, is not common in the
recent condition. It has been found, according to the ‘ Challenger’ Report, off
the western coast of Scotland, and off the north-east of Ireland; in the
Mediterranean off Malta; off Prince-Edward Island, Southern Ocean (50 to 150
fathoms); at one station in the North Pacific (1850 fathoms) ; and in the South
Pacific (1825 fathoms). Dr. Goés has it among the Arctic Foraminifera.
Fossil specimens have been recorded from the Oligocene (Septaria-clays) of
Hermsdorf and Pietzpuhl, and from the Miocene of Kostej in the Banat, Hungary.

Characters.—Shell much compressed, elongate, or subrhomboida]l. Chambers
elongate, oblique, arranged in two regularly alternating series. Septal lines
slightly excavated.
Note.—The name “ complanata”’ given by d’Orbigny, though later than some
others, has been adopted because of the good figure of the type.
Occurrence.—Polymorphina complanata is rare in the recent condition (coast of
Galway). As a fossil it has been recorded from the Chalk of Maestricht ;
POLYMORPHINA FRONDIFORMIS. 271
from the Miocene of Vienna; and from the Upper Tertiaries of north-west
Germany. We have specimens from the Casterlian of Antwerp; and Mr. Millett
has recorded it from the Pliocene of St. Hrth. In the Coralline Crag we have
found it in every zone examined.

Charactei's.—Shell large, elongate, compressed or complanate, unsymmetrical.
Chambers long, oblique, irregular. Surface depressed over portions of the septal
lines; sometimes smooth, but more frequently marked by exogenous shell-growths,
either in the form of rounded beads or short, interrupted coste.
This form is related to P. complanata (megalospheric ?), but peculiar in its
habit and locality. The ornamentation is very peculiar, and does not exactly
correspond with what is seen in allied genera. It consists (as in P. myristiformis)
of clear, bright, circular or oval beads, or of more or less interrupted costule of
the same sort, distributed irregularly in longitudinal direction over the flat sides
of the shell.
14*, Var. BREVIS.
Pl. VII, fig. 20, illustrates a varietal form, var. brevis, subovate in outline, with
relatively shorter and fuller chambers, ornamented chiefly near the edge with
irregular and subquadrate drop-like beads, such as occur among the costule on
other specimens.
272 FORAMINIFERA OF THE CRAG.
14**, Var. LINEATA.
Pl. I, fig. 69, may be the young form of P. frondiformis, but is probably a small
variety (var. lineata), more regularly ovate in outline, with its edges entire, its
chambers fuller, and its surface ornamented with delicate longitudinal sculpturing,
somewhat like that of P. puchella, d’Orb., and still more like that of the “ striato-
fistulose specimen from the Crag (‘ Trans. Linn. Soc.,’ vol. xxvii, pp. 246 and 252).
This specimen seems to have been lost; and unfortunately the figure escaped
notice when the new plates and woodcuts were being drawn.
Occurrence.—As far as is at present known, Polymorphina frondiformis is
absolutely peculiar to the Coralline Crag of Hast Angha. At the time of the
publication of the First Part of this Monograph, it had been found at Sutton only.
We have now obtained specimens, with varying frequency, from every zone
examined.

Characters. — Shell suboblong, compressed, asymmetrical, few-chambered.
Margin rounded, somewhat constricted at the septal lines. Chambers slightly
inflated. Surface uneven, studded with irregular angular depressions imparting a
mottled appearance to the whole exterior. Orifice variable ; simple or labyrinthic.
These large Polymorphine from the Crag have a surface-ornamentation that
has not been observed in specimens from other localities. It consists of unequal,
irregular, angular depressions, sometimes bordered by a slightly raised line. The
shell-wall is coarse and thick; and the terminal orifice sometimes differs from the
normal circular aperture, becoming labyrinthic, or even divided into two or three
distinct perforations.
Ocewrrence.—Polymorphina variata, like P. frondiformis, appears to be confined
to the Coralline Crag of East Anglia. It has been found in every zone we have
examined ; but most plentifully at Sutton (zone f), and Sudbourne Hall (zone qd).

recent condition. Fossil specimens have been found in the Gault of North
Germany ; in the Miocene of Vienna (d’Orbigny), Lower Bavaria (Egger), and
Kostej in the Banat (Karrer) ; also in the Casterlian of Antwerp.
The figured specimen is from the Coralline Crag, probably of Sutton,

mentioned in the ‘‘ Monograph on the genus Polymorphina,” by Brady, Parker,
and Jones, namely from the West Indies.
Fossil specimens seem to be rare. The records are from the Oligocene of

17*. Note on Potymorrnina ruGosa (Part I, Appendices I and II, see above).
It is quite possible that P. rugosa had been noticed in the collections from the
Crag, but lost sight of; and that the P. hirsuta subsequently observed may be
quite distinct from the formerly recorded specimen of P. rugosa. A figure of the
latter is therefore given here, since it may have occurred, and may be found again
in the Crag.

Characters.—Shell elongate, subcylindrical, straight, or nearly so. Anterior
portion acuminate ; posterior obtuse, and rounded. Larly (alternating) chambers
varying greatly in their proportion to the whole shell. Later (uniserial) chambers
two to six in number, more or less inflated.
As explained in the ‘“‘ Monograph of the Genus Polymorphina,” 1870, p. 249,
there is no essential difference between d’Orbigny’s Dimorphina tuberosa and his
symmetrical D. nodosaria. So also D. deformis (Costa) appears to differ only in
degree, by irregularity of growth, from D. tuberosa; and our fig. 21 of Pl. VII
is within the varietal limits of the same species, though more even and fusiform in
shape.
Taking the subcylindrical Polymorphine of the Crag as a group, we see that
Pl. I, figs. 55—58 represent a type; Pl. I, fig. 61, is a tuberose subtype; Pl. VII,
fie. 21, is less tuberose and more fusiform; whilst Pl. VII, fig. 17, is compressed
and almost Marginuline in growth, with an eccentric beginning and uniserial
upgrowth; and Pl. I, fig. 66, is still more compact and like a Marginulina in
outline. The two latter forms are described under a separate trivial name.
A compressed form, very close to D. tuberosa, has been found in the Pliocene
beds at St. Erth, by Mr. Millett.
Occurrence.—Dimorphina tuberosa is of rare occurrence both in the recent and
fossil condition. Living specimens have been obtained from the Mediterranean at

depths not exceeding 100 fathoms. Fossil specimens have come from the Oligocene
of Hermsdorf; Miocene of Vienna and Italy ; and from the Pliocene of Garrucha,
in Spain.
In addition to the figured specimen (PI. I, fig. 61) from Sutton, we have found
well-developed specimens from the same place in zone f.

Characters.—Shell elongate, subcylindrical, more or less arcuate, compactly
built ; anterior extremity obtuse or truncate; posterior rounded. Margin even ;
septa marked by faint lines.
Fig. 66, Pl. I, the specimen described in the ‘“‘ Monograph of Polymorphina,”
1870, was separate from D. tuberosa on account of its marginuline form with
compressed oblique uniserial chambers. Fig. 17, Pl. VII, also has a quasi-
marginuline style of growth ; and, although it is not so elongate and narrow as the
other, its general outline and compact structure show its close alliance.
D. compacta, but having a slit-like aperture, has been met with by Mr. F. W.
Millett at St. Hrth. Moreover, a compressed Dimorphine Polymorphina has been
found by Mr. Millett in these Pliocene beds, and described and figured by him in the
‘Trans. Roy. Geol. Soc.,’ Cornwall, vol, xi, part 9, 1895, p. 658, pl. o, figs. 5, 6
a, b, as Polymorphina regularis, var. parallela.
Occwrrence.—Dimorphina compacta is not known in the recent condition.
Excepting the above notice of its occurrence at St. Erth, the only record of its
having been found is from the Coralline Crag of Sutton, whence both of our figured
specimens were obtained.

Occurrence.—Uvigerina angulosa has been found in almost all seas at depths
ranging from 2 to 1630 fathoms (‘ Challenger’) and 2328 fathoms (‘ Gazelle’).
Fossils specimens have been recorded from the Miocene of Malaga and Italy ;
the Pliocene of Italy, St. Erth, and Antwerp (Casterlian). In the Coralline Crag
we have specimens from nearly every zone examined.

bathymetrical range. The ‘ Challenger’ records as to depth vary from shore-
sands to 1900 fathoms; and the specimens were obtained from several widely
separated stations in the North and South Atlantic, and in the South Pacific.
Egger, in his Memoir on the Foraminifera obtained by the ‘ Gazelle,’ records
specimens from off the coasts of Mauritius, Western Australia, and New Guinea.
We have specimens in our own collections from soundings obtained by
H.M.S. ‘ Penguin’ from two stations in the Indian Ocean, one of them due south
of Ceylon, at depths of 1040 and 1277 fathoms respectively.
In the fossil condition specimens have been obtained from the Chalk of Taplow ;
the Miocene of Vienna and Muddy Creek (Victoria), and the Pliocene of Kar
Nicobar. In the Coralline Crag we have specimens from Tattingstone, zone d;
Sutton, zone e; and Gedgrave, zone f. In the First Part of this Monograph,
U. Canariensis (* U. irregularis’’) was recorded from the Red Crag (Appendix I,
Table, No. 59; App. II, Table, No. 73); but the specimen has been lost. Var.
farinosa (Hantken) is from the Tertiary of Hungary.
Fanily 4.—GLOBIGERINIDA.
General Characters.—Test free, calcareous, perforate; chambers few, inflated,
arranged spirally ; aperture simple or multiple, conspicuous. No supplementary
skeleton nor canal-system. Some of the larger forms pelagic in habit.

Probably no single type of recent Foraminifera has attracted as large an
amount of attention as Globigerina, partly from its exceedingly wide distribution
and its extraordinary abundance, but more from the interesting questions of
life-history, and even of physical geography, which are associated with its
occurrence.
The type appears to admit of some amount of variation in external characters,
though these exist within narrower limits than is often the case; the differentia-
tion from the central form being chiefly in respect to the greater or less regularity
in mode of growth, the number and sphericity of the segments, and the varying
condition of the surface and texture of the shell.
Whilst conscious that the whole of the modifications arising in these ways may
be connected in unbroken series with the central form, and consequently that
there is no ground for specific subdivision in any right sense, we are bound to
admit the convenience of recognising the names applied by various authors to the
more prominent and best-marked forms, and to accord to them a certain sub-
specific or varietal value.

consisting of about two conyolutions, composed of
highly globular segments, which increase very rapidly in size; the outermost
convolution usually containing four segments, visible on the inferior surface, the
remainder visible only on the superior surface. Orifice very large on the lower
umbilical margin of the much inflated ultimate segment. Frequently the
individual chambers open directly into the deep central umbilicus of the inferior
surface. Our figs. 1 and 2, in Pl. II, represent a small typical Gl. bulloides.
GLOBIGERINA LINN AANA. 285
Oceurrence.—Globigerina bulloides is a cosmopolitan species, found at all
depths. Its earliest recorded appearance is in the Devonian (Terquem, ‘Bull.
Soc. Géol. France,’ ser. 3, vol. viii, 1880, p. 418, pl. xi, figs. 10 a—c) ; it occurs in
the Jurassic (Terquem and Hausler) ; it is abundant in the Chalk-mar] and Chalk ;
and it has been found in nearly all subsequent marine deposits.
It forms an important constituent of the existing sea-bed wherever the depth
of water exceeds 100 fathoms. At smaller depths it is comparatively rare; but
it abounds on some coasts, and chance specimens have been found in brackish
shallows, and even in the rivers of the Fen districts of Lincolnshire at a distance
from the open sea.
Globigerina bulloides is one of the pelagic species collected by towing nets in
the open ocean, in company with two or three species of Pulvinulina.
It seems that the Crag sea was not very favorable to the existence of this
species; small specimens, however, are found throughout the Coralline Crag,
and in the Upper Crag of Southwold.

Characters. — Rotaliform, compressed, slightly convex above, somewhat
concave with a sunken umbilicus below; edge square and bicarinate, hence
canaliculate; chambers numerous, strongly limbate; apertures opening in the
umbilicus; surface rough.
Occurrence.—The only record of this species in the recent condition appears to
be that of the original from the shore-sands of the Island of Cuba. It is a
common Cretaceous fossil, but it does not appear to have been met with in later
deposits until we found specimens in the Coralline Crag of Sudbourne and Broom
Hill (both zone 4).
1 Beissel refers also to the ‘ Mikrogeologie,’ pl. xxvii, figs. 57, 58, which occur among young
and adult forms of Gl. eretacea (figs. 53—59, and perhaps 60—64) (see ‘ Ann. Mag. Nat. Hist.,’
ser. 4, vol. ix, p. 294). These falsely appear to be marginate, owing to the translucent edges of the
chambers (seen by transmitted light), as is the case with many figures in this and other plates.

Characters.—Shell small, subglobular, and like Nonionina in shape; chambers
convex, four or five in each of the three or four whorls, each of which completely
invests the previous whorl. The septal face arched, narrow, and bearing the long,
transverse, crescentic, slit-like aperture in the under part of the chamber.
Surface smooth, and suture slightly depressed. Figs. 31, 32, in PI. II, are fairly
typical.
Occurrence.—Pullenia spheroides is a cosmopolitan species; most commonly
met with at depths exceeding 300 fathoms. Specimens have been found as low
down as 2750 fathoms. ‘The list of localities at which this Foraminifer has been
taken are thus given in the ‘ Challenger’ report :—Davis’ Strait, Novaya Zemlya,
East Coast of Norway, Farée Channel, British Seas, Mediterranean, Red Sea,
North and South Atlantic, Southern Ocean, and the South and North Pacific.
An examination of material collected by H.M.SS. ‘Stork’ and ‘ Penguin’
enables us to add to the above list five stations in the Indian Ocean (1040—2694.
fathoms).
The geological range of the species extends to the Cretaceous period. It has
been found in the Chalk of Westphalia and Ireland, in the Hocene (London Clay),
in the Oligocene of Elsass and Germany, in the Miocene of Vienna, Malaga, the
Banat (Karrer), and Malta (Brady), and in the Pliocene of Italy and Garrucha.
288 FORAMINIFERA OF 'THE CRAG.

surface, and only those of the last whorl on the inferior or apertural side; some-
times one face being more convex, sometimes the other. Aberrant forms evolute,
outspread, acervuline, or irregular. Some of the more highly modified forms
have double chamber- walls, supplemental skeleton, and a canal-system.

Characters.—In the type-form the shell is discoidal, thin, sometimes concave
in the middle; rounded on the edge, the whorls being sub-cylindrical, rarely
embracing, but the later usually larger in diameter than the earliest; bearing
numerous conspicuous foramina.
The variety here figured differs from the type-form im being marked by a
single row of impressions or perforations along the inner edge of the sub-
cylindrical tubular whorls. We had prepared to call it unilinearis, but Dr. G.
Schacko, of Berlin, has figured and described a very similar, if not identical form,
as above quoted. The large perforations along the suture-line, besides the fine
general perforation, are characteristic. The apparent granulation of the surface
in his specimen M. Schacko attributes to a partial decalcification of the shell.
290 FORAMINIFERA OF THE CRAG.
Occurrence.—Spirillina vivipara (with its varieties) has a world-wide distribu-
tion in comparatively shallow waters. ‘lhe lowest depth from which specimens
were obtained by the ‘ Challenger’ was 620 fathoms.
Fossil specimens are comparatively rare. It has been obtained from the
Miocene of Vienna and Lower Bavaria, the Pliocene of St. Erth, and the
Pleistocene of Ireland. In the Coralline Crag we have specimens of the type-form
or varieties from nearly every zone examined. Fig. 22 represents a specimen
from Broom Hill. Dr. Schacko describes his Sp. minima as being abundant in
the Chalk of Rugen.
1**, SPIRILLINA VIVIPARA, Hhrenberg, 1841, var. compLanaTa, nov. Plate III,
figs. 20—22.
Part I, 1866 (“‘ Spirillina vivipara”’), Appendices I and II, Tables, No. 75.
In figs. 20—22 we see all the characters of Spirillina vivipara excepting that
the edge is obliquely steep,—that is, the tube, instead of being circular in section,
has an obliquely oblong sectional area, and the shell is flat above and below, the
sutures being quite flush with the surface, and the whorls not at all overlapping
one another.
Hence we must regard this figured specimen as a variety (var. complanata).
The oblique periphery is seen also in Brady’s Sp. inequalis, Rep. ‘ Challenger,’
p. 631, pl. Ixxxv, figs. 8—11.
Oceurrence.—For that of the type-form see above. ‘The figured specimen
(Pl. IIT, figs. 20—22) was collected by Mr. 8. V. Wood in the Sutton Crag.
Sub-family 2.—Roraina.
Test free or, rarely, attached, somewhat ammonitiform (rotaliform), and some-
times acervuline. Aperture usually or normally a crescentic slit on the inferior
face of the shell.

292 FORAMINIFERA OF THE CRAG.
Characters.—Shell trochoidal, upper face conical, lower face nearly flat ; many
chambers visible in the spire, five to nine shown below.
Occurrence.—This species, which is the type of the genus, is rather rare in the
recent condition. The ‘ Challenger’ obtained specimens off Cape de Verde Islands
(11 fathoms), off Ascension (420 fathoms), near Pernambuco (350 fathoms), and
at Port Jackson (2 to 10 fathoms). Brady also records specimens from the coral
sands of Bermuda, and from Port Stephens, New South Wales. The ‘ Gazelle’
obtained specimens from one station only, off Mauritius (223 fathoms).
The fossil records are from the Chalk of Maestricht ; the Neocomian (Bargate
Beds of Surrey) ; the Eocene (Calcaire Grossier) ; the Miocene of Calabria and of
Muddy Creek (Victoria); and the Pliocene of St. Erth.’ In the Coralline Crag
we have specimens from Tattingstone and Broom Hill, zone d, from Sutton,
zones ¢ and f, and from Gedgrave, zone f.

Characters.—Helicoid shell, with low spire, showing several chambers, inflated,
especially the last, sutures depressed, rarely limbate, lower face of shell nearly
flat, showing about five chambers.
Occurrence.—Discorbina globularis has a wide geographical range, having been
found in nearly all seas from Davis Strait in the North to Magellan’s Strait in
the South. It is more common in temperate and sub-tropical waters; and has
not, according to the ‘ Challenger’ Report, been yet found at depths greater than
450 fathoms.
Fossil specimens have been found in the Hocene, London Clay, and Calcaire
Grossier, the Miocene of Bavaria, Southern Italy and Muddy Creek (Victoria), the
Pliocene of Italy and St. Hrth, and in the Pleistocene of the British Isles, Italy,
and elsewhere (Brady). It is not a common fossil in the Coralline Crag. The
figured specimen is from Tattingstone, zone d.

Characters.—Shell trochoid, conical, composed of three to four convolutions
each consisting of from four to seven segments. Segments convex on their
DISCORBINA ORBICULARIS. 295
anterior and peripheral borders, imparting thereby a lobulate outline to the
margin of the shell. Anterior border of each segment overlapping the posterior
portion of that immediately in front of it. Inferiorly the outlines of the segments
less distinct, usually marked by irregular sinuate lines extending from the peri-
phery to the umbilicus or near it. Aperture a long, narrow, arched fissure on
the inferior umbilical border of the ultimate segment.
Occurrence.—Discorbina rosacea is exceedingly common, and according to the
‘Challenger’ Report, ‘‘ within certain depths it is found in almost every sea,
from the shores of Shetland and the Farée Islands on the north, to Magellan’s
Strait on the south. Its home is on shallow bottoms, and it becomes rare at
greater depths than 250 fathoms; but occasional specimens are met with as low
as 1000 fathoms.” In contrast with this, Egger in his ‘ Gazelle’ memoir records
specimens from depths ranging from 13 to 2740 fathoms, and the larger number
of his records are from depths exceeding 1000 fathoms. The figures given by
Keger in his pl. xv, however, suggest a doubt in our minds as to the proper
identification of the species.
The geological distribution of D. rosacea extends to the Neocomian (Bargate
Beds). Specimens have also been recorded from the Hocene (London Clay and
Calcaire Grossier), the Miocene of Vienna, Muddy Creek (Victoria), and Italy,
the Pliocene of Italy and St. Erth, and the Pleistocene of the British Islands and
the Island of Ischia. In the Coralline Crag we have specimens from nearly every
zone examined ; and, as recorded in the First Part of this Monograph, the shell
has also been found in the Upper Crag of Southwold,

Characters.—Test thin, depressed, slightly conical above, flat or nearly so
below. The upper face shows numerous, long, narrow, curved, and overlapping
chambers; the last the longest. Sutures usually simple, sometimes slightly
limbate. On the lower face only three or four chambers visible, the last much
the largest. Umbilical flaps present.
Occurrence.—Discorbina orbicularis has a very wide geographical and bathy-
metrical range, but it has not hitherto been found in Arctic or Antarctic waters.
The Irish Sea appears to be the most northern limit known. The ‘ Challenger’
Report states that it is plentiful in the shallow water among the Pacific Islands,
and also amongst the West Indies. Egger, in his ‘ Gazelle’ Memoir, records it
from the Cape Verde Islands and other points off the West Coast of Africa,
Mauritius, Western Australia, and the Atlantic Ocean. The greatest depths
recorded in the ‘ Challenger’ Report 1s 435 fathoms; but the ‘ Gazelle’ obtained
specimens from a depth of 2590 fathoms in the South Atlantic Ocean.
As a fossil it has been recorded from the Neocomian (Bargate Beds of Surrey),
the Miocene of Italy and Muddy Creek (Victoria), and the Pliocene of Italy and
St. Erth. In the Coralline Crag we have found it in every zone examined.

Characters.—Shell plano-convex, sometimes with an obtusely pointed apex ;
consisting of two or three convolutions of long, oblique, arcuate chambers, seven
to nine in a convolution; inferiorly the segments of the last convolution extend
to the umbilicus. Upper surface smooth; the last and the earlier chambers
variously exposed in different specimens; the sutures simple; the lower face of
the shell shows several curved and some intercalated chambers, and is ornamented
with radiating lines of minute tubercles. Peripheral margin thin, rarely lobulate.
Occurrence.—Discorbina parisiensis is generally of rare occurrence in the recent
condition, and appears to have a somewhat restricted range ; but it is not uncommon
in the shore-sand of Mount’s Bay, Cornwall (Millett). The ‘Challenger’ found
specimens only off Kerguelen at depths of 20 to 50 fathoms. The ‘ Gazelle’ found
specimens off Kerguelen, and also off Mauritius (70 to 220 fathoms); off South-
West Australia (2159 fathoms) ; and off West Australiaat less depths. Specimens
have also been obtained in shallow water off the coasts of Ireland and France.
The earliest record of the species in a fossil condition is from the Neocomian
(Bargate Beds) of Surrey. It has also been found in the Eocene (Calcaire
Grossier), and in the Pliocene of St. Erth. We have specimens in our own
collections from the Casterlian and Scaldisian of the Kattendyk Docks, Antwerp.
In the Coralline Crag we have found it in every zone examined, and it has also
been obtained (small and rare), as stated in the First Part of this Monograph, from
the Red Crag.

298 FORAMINIFERA OF THE CRAG.
Characters.—Test compressed, flat or concavo-convex; periphery somewhat
Square ; sutures more or less limbate on the aboral (‘‘ superior ’’) face, and having
interlocking angles on the oral face. The aboral surface of several of the chambers
ornamented with a slightly raised boss.
We think Brady mistaken in admitting fig. 3 on pl. xci of the ‘ Challenger ’
Report as D. biconcava, P. and J. It has limbate sutures upon one side only, is
not biconcave, and has not a square limbate periphery. The aboral face (fig. 3 a)
is strikingly like our fig. 33 a, Pl. VII, and also like our specimens from the
Miocene of Muddy Creek (Victoria).
Occurrence.—The figured specimen is from the Coralline Crag of Sutton,
zone f; and, as mentioned above, we have specimens from the Miocene of
Australia exactly corresponding with the specimen from the Crag.

Characters.—Shell free at first, parasitic afterwards, thin, outspread, one face
(“superior ”’ and attached), somewhat flatter than the other ; the periphery almost
circular, subangular, or irregular. Chambers numerous, inflated, arranged sub-
cyclically on one plane; early spiral chambers visible in the middle of the
attached face; septal orifices somewhat obscure, but usually at both ends of the
outer chambers on the periphery.
Pl. II, fig. 3, represents a feeble individual of the Northern form vulgaris.
Occurrence.—According to the ‘ Challenger’ Report, this species occurs “in
almost every sea within the temperate and tropical zones.” It is commonest at
depths of less than 50 fathoms, but one specimen has been found at a depth of
1125 fathoms. Hgger in his ‘ Gazelle’ Memoir records the occurrence of rare
specimens at one station off Kerguelen Island.
Fossil specimens have been obtained from the Oligocene of Hlsass, the Miocene of
Vienna and Muddy Creek (Victoria), the Pliocene of Italy, Antwerp (Casterlian),
and St. Erth, and in the Pleistocene of many localities. In the Coralline Crag
we have examples from every zone examined.

Characters.—Shell free or parasitic, regular; conical or plano-convex. Oral
surface conical or dome-shaped, aboral surface flat or slightly concave ; chambers
long, arcuate, somewhat inflated. Foramina inconspicuous.
This is but an exaggerated condition of Jr. lobatula in which the convexity of
the oral surface is increased, sometimes so much as to give the shell the form of
a tall cone. The pseudopodial perforations are commonly obliterated by the free
deposit of shell-substance. In other respects the characters of Tv. lobatula apply
equally to Tr. refulgens.
Occurrence.—Truncatulina refulgens, according to the ‘ Challenger’ Report, is
confined to temperate seas, and occurs at depths of from 45 to 2400 fathoms.
Egger in his ‘ Gazelle’ Memoir records specimens from off Mauritius and North
Australia at depths of 74 and 194 fathoms respectively.
Fossil specimens have been obtained from the London Clay, the Pliocene of
Southern Italy, and from the Pleistocene of Ireland. In the Coralline Crag we
have specimens from Tattingstone, Sudbourne, and Broom Hill (zone d), and
from Aldborough (zone g). It has also been recorded in the First Part of the
Monograph from the Red Crag.

Characters.—Shell suborbicular, plano-convex, consisting of from two to three
convolutions, of which the outermost alone is visible on the convex surface. Each
convolution composed of seven or eight segments. Convex surface depressed at
the umbilicus. Segments ventricose on the upper, flat and truncate on the lower
surface of the shell. Orifice single, large, at inner margin of the terminal chamber.
Foramina conspicuous chiefly in young specimens.
Occurrence.—Truncatulina lobatula is found in all seas and at all depths down to
3000 fathoms. It is the most common of the Rotaline Foraminifera. Its
geological range is also very great. Specimens have been obtained from rocks of
Carboniferous age ; and it is commonly met with in Mesozoic and later deposits.
As a Tertiary fossil its range is similarly wide, and the amount of attention that
has been bestowed upon it by naturalists may be seen from the table of synonyms
given above.
In the Coralline Crag it is common in every zone we have examined; and it
has also been found in the Upper Crag, as recorded in the First Part of the
Monograph.

Character.—In shell-structure similar to Truncatulina lobatula, but losing its
relatively spiral arrangement in a wild-growing irregularity of the chambers in an
apparently infinite variety of forms.
Occurrence.—This varietal form of T. lobatula has a geographical and bathy-
metrical range corresponding with the type. Its earliest recorded appearance as
a fossil is from the Neocomian (Bargate beds of Surrey); it has also been found
in the Gault, the Red Chalk, the Phosphatic Chalk of Taplow; the Miocene of
Bavaria and Muddy Creek (Victoria), the Pliocene of Italy and St. Erth. In the
Coralline Crag it is found somewhat rarely in every zone we have examined.

312 FORAMINIFERA OF THE CRAG.
Characters.—Shell orbicular, formed of from three to four revolutions of a
spire, each consisting of six or seven chambers. Aboral surface more or less
trochoid; the other (oral or inferior) face subconvex, often excavated at the
umbilicus; formed of about six triangular chambers extending from the
periphery to the umbilicus. Margin blunt, scarcely angular. Foramina
numerous and conspicuous over every part of the shell.
Between the neat, well-defined, highly trochoid shell figured by d’Orbigny and
the somewhat clumsy, indefinite examples of the same species found in the Crag
there seem, at first sight, to be few characters in common; yet there need be no
hesitation in regarding them as the same form. It is rare under any circum-
stances to meet with specimens so distinct in all external characters as the
figures in the ‘‘ Vienna Basin” monograph indicate ; and, on the other hand, the
few which have been found in the Crag (from Sutton and Sudbourne), though of
average size, have their structure obscured either by the thickening of the shell
wall from age, or by the mechanical effect of attrition.
Occurrence.—Truncatulina Haidingert is not of frequent occurrence in the
recent condition, though it has a wide range geographically. It has been found
at various depths down to 1776 fathoms (‘ Challenger’ Report) and 2140 fathoms
(‘ Gazelle ’).
In the fossil condition it appears to be more common. Specimens have been
found in the Neocomian (Bargate beds of Surrey); the Hocene (London Clay and
Calcaire Grossier); the Miocene of Malaga, Italy, Vienna, and Muddy Creek
(Victoria); and the Pliocene of Italy, Garrucha, and St. Erth. In the Coralline
Crag we have found examples in nearly every zone examined.

Characters.—Shell free, orbicular, depressed; consisting of about three
revolutions in a complanate spire; aboral side convex, depressed at the umbilicus ;
oral surface nearly flat; periphery thin, often acutely carinate. Chambers
numerous (8—12), convex, extending to the umbilicus, and bounded by sinuous
septal lines on the aboral side. Foramina generally very numerous and con-
Spicuous; oral surface of the shell often granular.
The regular Planorbuline present so unbroken a series that it must always be
a matter of individual judgment, rather than one of strict rule, how its subdivision
should be effected. Hence, out of deference to the opinion of other authors, we
have presented a somewhat limited synonym of P. Ungeriana, else we know of no
permanent characters which would have precluded our adding P. Akneriana and
many other so-called species to the list ; for example, Rotalina tuberculifera, Reuss,
Rotalia granosa, Reuss, Truncatulina horrida, Karrer, which differ from the
normal form in their increased tendency to a granular or tubercular condition,
especially of the lower surface.
Occurrence.—Truncatulina Ungeriana has a wide geographical and bathy-
metrical range. The ‘Challenger’ Report records its occurrence in the North
and South Atlantic, the North and South Pacific, and the Mediterranean. We
have numerous specimens in our own Collection from the Indian Ocean.
In a fossil condition it has been recorded from the Cretaceous of Swanscombe,
Kent; the Eocene (London Clay); the Oligocene of Germany ; the Miocene of
Malaga, Italy, Vienna, and Muddy Creek (Victoria), and the Pliocene of Garrucha
(Spain), Italy, and St. Erth. In the Coralline Crag we have it from every zone
examined.

TROCHOTOMA. 445
Fenus—TrocHotoma, Deslongchamps, 1842.
*¢ Shell trochiform, conical or depressed ; base infundibuliform ; whorls but slightly
convex, keeled ; sinus band obliterated up to the lip, with the exception of an oblong
jissure, choked in the middle, bipartite; aperture subquadrangular, oblique; lip
simple and without slit; columellar lip deeply sunk in the false wmbilicus, entire,
sinuous.’ —FIscHER.
Specimens in our Inferior Oolite, which exhibit the more interesting characters
of this genus, such as the strangulation of the fissure, and the sinuous or toothed
character of the columellar lip, are exceedingly rare. This partly arises from the
false umbilicus being plugged up with matrix. The toothed character of the
columellar lip is well shown in a specimen of Tvochotoma Lindonensis, from
Lincoln (Pl. XUI, fig. 9). Fischer in 1885 constituted the section, Didymodon, on
this feature, the type being T'rochotoma quinquecincta, Zieten, from the Corallian
of Nattheim, which in many respects resembles the Lincoln specimen.
The genus T’rochotoma in this country is mainly confined to the Lower Oolites,
being most abundant in the Bathonian section. The lowest horizons of our Inferior
Oolite in Dorsetshire contain some forms which in Normandy are quoted from
the Lias, such as Trochotoma gradus. We may admit that 1’. gradus, T. affinis,
and 1’. calizv are little more than varieties of one tabulate form.

Bibliography, §c.—On the view that we should separate 7’. calix from T. gradus
and 1’. affinis, the synonymy given by me in the ‘ Geol. Mag.’ is too comprehensive.
The type specimen of Solarium caliz is not, I believe, to be found at York,

but Phillips’ figure is characteristic. There are two varieties in the Dogger
which we may refer to 7’. caliz. Specimens are not uncommon, but the state of
preservation is indifferent.
Description (more depressed variety) :
Height : : : » » 3 Oamon.
Basal diameter ‘ ‘ : . 24mm.
Spiral angle about . . be oan
Shell trochiform, tabulate, and Proeoundly Pere tated Whorls (five) nearly
rectangular, with a close suture. In some specimens the whorls of the spire show
only one keel; but in others, where the spire is relatively higher, a lower keel is
exposed. The upper keel is situate at the angle, and carries the obliterated fissure-
band. Spiral ornament regular and in raised lines, which are somewhat wide
apart (see fig. 7) and ropy, the sides of the whorls being somewhat concave.
The body-whorl exhibits a well-defined lower keel which is thick and sub-
angular at the periphery; hence the body-whorl is strongly bicarinate and
subconcave. The base is widely excavated. The aperture is depressed and
oblique, but the available specimens from the Dogger do not admit of any close
description. ‘The loop is long and narrow, and its presence is often indicated on
the upper keel by a raised border. In other specimens the loop, having been a
source of weakness, causes a deflection in the continuity of the keel.
The variety from the Cotteswolds (figs. 1a, 1b), which presents features inter-
mediate between 1’ calix and T. affinis, has a narrower spiral angle and a larger
habit of growth. In some of these specimens it is possible to note the sinuous
character of the columellar lip.
felations and Distribution—The features on which it is relied to separate
T. ealix from its undoubtedly close relatives, 7. gradus and 1’. affinis, are possibly
of little biological value. There really is very little difference except as to size,
and, to some slight extent, in ornamentation. The truth is that all these tabulate
Trochotomas are very much alike. Yet in the Dogger and partially also in the
Cotteswolds certain small forms or races prevail which we know as T. caliv;
whilst in the Anglo-Norman area larger and more markedly tabulate forms, such
as 7’. gradus and 1’. affinis, occupy the ground.
T. cali is fairly abundant in the opalinus-zone (Dogger) of Yorkshire, and
a very similar form, with a very thick basal rim, occurs in the opalinus-zone of
Frocester Hill. In the Oolite-Marl horizon (Murchisonx-zone) we also get these
small forms with the thick basal rim, as well as others of a larger size (figs. 1 a, 1b)
where this feature is not soconspicuous. Inthe base-bed at Lincoln (Murchisone-
zone) are forms showing the connection between 1’. caliz and T. Lindonensis.

Bibliography, §c.—The fossils described under the above title are not exactly
the same as 7’. gradus, which in Normandy is regarded as a Liassic species. They
are in fact intermediate between 7’. gradus and 1’. affinis.
Description :
Height . , : . . 28—30 mm.
Basal diameter. : . 40 mm.
Spiral angle : ; : "9b"
Shell trochiform and broadly tabulate, with a somewhat obtuse apex; whorls
of the spire almost rectangular and increasing by wide steps, being strongly
angulated towards the middle. The ornaments consist of regular spiral lines,
which pervade the entire shell and are somewhat wide apart; the lines are
decussated obliquely. Sutures close.
The body-whorl is strongly bicarinate, the anterior carina forming a blunt
angle at the periphery, whilst the space between the caring is considerably
excavated. The base is infundibuliform and rounded towards the periphery, which
is striated like the spire. Aperture for the most part concealed in all specimens
available to me.
Relations and Distribution.—This is a tabulate form of Trochotoma. All my
specimens are from Coker, occurring in beds which yield such an abundance of
Cirrus (Murchisone-zone). Tawney mentions its occurrence at Dundry, but
possibly this might be held to include 1’. affinis.

This is a less broadly tabulate form than the one pheviguels described, the
whorls being higher and the apex sharper. In some cases also the whorls are
more numerous (six to seven). In other respects similar to 7’. gradus.
Relations and Distribution.—The figured specimen is from Stoford, and may
be taken as the representative of T. affinis. Lycett figured his 7. carinata with
the fossils of the Spinosa-stage.
As before observed, we are almost entitled to look upon T. calix, T. affinis, and
T’. gradus as varieties of one species; where 1’. gradus is a large tabulate form
with about six whorls and an obtuse apex, 7’. affinis is a large subtabulate form
with higher whorls and a sharper apex; whilst 7’. calix is a small subtabulate form
with five whorls and a very obtuse apex.

strongly bicarinated. It is nearly related to “ T. discoidea, Rémer,’’ of the Great
Oolite Mollusca, and may be the same as that form.

Description :
Height : : ‘ : oe) Minin
Basal diameter ‘ : : « a mame
Spiral angle . : ‘ sly,
Shell thick, conical, subtabulate, and largely excavated. Spire rather obtuse
at the apex, otherwise regular. Number of whorls five to six; these are angular
with a narrow tabular ledge and steeply sloping flanks; sutures slightly canali-
culate. The ornaments are sharp and conspicuous; the narrow posterior flat
area of each whorl is marked by a strong granular spiral line between two deep
sulci; the upper carina at the angle of the whorls is boldly prominent and somewhat
subdivided, although there is no actual fissure-band ; there is a single spiral rather
below the middle of the side of the whorl (fig. 8 a), and this is followed by a sort
of double basal keel, which causes the whorls of the spire, except at the extreme
apex, to be bicarinate.
The body-whorl is strongly bicarinate with a very full and bluntly angular
periphery, which is spirally striated up to the margin of the excavation. The
loop is long and narrow. The aperture is subquadrangular, but curiously indented
owing to the sinuous and toothed character of the columellar lip ; the outer lip is
thin at the margin, but tcothed and grooved internally, in connection apparently
with the loop.
Relations and Distribution.—The Lincoln shells are, in some cases, so well
preserved as to exhibit characters which may exist in other British specimens of
Trochotoma, but are yet obscured by the plugging of the basal cavity; hence a
comparison with 7’. caliv, for instance, is difficult. 1. Lindonensis is related to
T. caliz just in the opposite direction to the latter’s affinity for 7. gradus. But it
is distinguished from 1’, calix by its more conical outline, higher spire, and narrow
tabulation ; also by the invariable bicarination of the spire whorls, and the very
considerable difference in the details of ornament. The specimen figured by
Lycett as 7. calix from the Mimbria-stage of the Cotteswolds possesses some of
the features of 7. Lindonensis, especially as regards ornament, and seems to be a
kind of intermediate form.
On the other hand, 7. Lindonensis presents a strong resemblance to 7’. quinque-
450 GASTEROPODA OF THE INFERIOR OOLITE.
cincta, a Corallian species, and may possibly be identical. 1. Lindonensis is rather
abundant in the ‘‘ base-bed”’ at Lincoln (Murchisonx-zone), where it seems to
replace T. caliv. Specimens of Trochotoma from the Ironstone of Duston also
possess considerable resemblance to the Lincoln shells.

Bibliography, §c.—The acceptance by Morris of this species as an Inferior
Oolite fossil is a strong point in its favour, but owing to the absence of any
material evidence it was not listed by Hudleston and Wilson. Since that time a
specimen answering fairly well to Lycett’s diagnosis has been obtained from the
Pea-grit of Nailsworth Hill. In some respects this specimen reminds me of
Plewrotomaria.’

«“ Blevated, acuminated, nearly area . eons Pat convex, their ees portions

tion contracted. Height about equal to the basal diameter.”’
The aperture of the figured specimen has greatly the aspect of Plewrotomaria,
put I cannot find any trace of the sinus-band.
Famity—FISSURELLIDA.
Shell conical, limpet-shaped; apex recurved; nucleus spiral, often disappearing
in the course of growth; anterior margin notched or shell perforated ; muscular
impression horseshoe-shaped, open in front.
There are three genera of this family in the Inferior Oolite, Rimula being the
most characteristically developed. In the case of Hmarginula the anterior notch
is not always in evidence. It is probable that the shelis in the Jurassic Rocks
1 Lycett also described ‘‘ Plewrotomaria funata.”
EMARGINULA. 451
hitherto referred to Fissurella belong to another genus, possibly to Puncturella.
I have never seen either in the Inferior Oolite or the Great Oolite a true keyhole
Limpet.*
I have not seen any members of this family in the Dorset-Somerset district,
nor in the Yorkshire Dogger. Inferior Oolite specimens are from the Cotteswolds
and the Lincolnshire Limestone, but in all cases somewhat rare.
Genus—EmarGinuna, Lamarck, 1801.

Shell elevated, apex posterior, periphery ovate, with slight expansion of the
anterior area. The ribs, about seventeen in number, are nearly equal and

prominent, but considerably narrower than the intercostal spaces. The latter are
traversed by a system of cross-lines or lamellz, giving the shell a scaly appearance
(scarcely seen in the figured specimen). The two ribs which enclose the fissure
approximate, but of the length of the fissure it is not easy to speak with certainty.
The margin was probably crenulate.
Relations and Distribution—This form, which most nearly approaches
E. scalaris of the Great Oolite, is fairly abundant in what is believed to be the
upper part of the Lincolnshire Limestone at Spittlegate Quarries. The species is
quoted by Lycett from the Inferior Oolite of Leckhampton, but I have not seen any
satisfactory specimens from that quarter.

Shell elevated, apex very posterior, periphery ovate and rather expanded

intercostal spaces have closely-set lamellae which infringe upon the coste and
produce a granular appearance; very fine intermediate coste may also be noticed.
There is but slight approximation of the pair of ribs which contain the fissure.
RIMULA. 453
Relations and Distribution.—This is an elegant little shell belonging to the
more highly ornamental species of Hmarginula, represented in the Great Oolite by
Hj. Deslongchampsi, Cossmann. The number of ribs and general ornamentation
answer to H. Leckhamptonensis, Lycett. But this is an elevated species, whereas
H. Leckhamptonensis isa depressed one. ‘The *‘ base-bed ” at Lincoln has furnished
the type, besides two smaller forms of similar shape but with fewer ribs.
The specimen (Figs. 18 a, 13 b) from the Lincolnshire Limestone of Stoke Lodge,
with much the same dimensions and ornamentation, has a less oval periphery and
only twenty ribs. In some respects this form seems intermediate between
H. scalaris and LH. Lindonensis.

Bibliography, §c.—There must have been something unusually satisfactory in
this species to induce Morris, who ignored the majority of Lycett’s Inferior Oolite
list, to give it a place in his catalogue. Hudleston and Wilson did not recognise
it. Lately, however, the Brodie-Lycett collection has been acquired for the
Jermyn Street Museum, and what purports to be a named specimen from the
shelly freestones of Leckhampton is available for inspection.

structure as those of more recent date.

Bibliography, §c.—Hssentially a Great Oolite species, the type being from
Ancliff, rare at Minchinhampton ; stated by Cossmann to be tolerably abundant
at Epernay. Quoted by Lycett from the Inferior Oolite, Leckhampton. I have
not seen satisfactory specimens myself from that locality. On the other hand, the
Lincolnshire Limestone, which contains so many Bathonian forms, has yielded
quite a series of fossils at Stoke Lodge, which may fairly be ranked under
h. clathrata, though somewhat more angular in outline than the Ancliff shells.
Description (Inf. Ool. variety) :
Length of base ; . 6mm.
Width approximate : . 4°5 mm.
Height ; . 5mm.
Shell capuliform with a perfectly oval base and curved apex, which projects
considerably beyond the posterior margin. ‘The convex dorsal area is somewhat
flattened on each side of the very conspicuous midrib, whichis separated from the
ribs of either flank by a considerable space. From eight to ten strong longitu-
dinal ribs on each side ornament the surface, and these are strongly decussated by
transverse ribs producing nodes at the points of intersection: subsidiary longi-
tudinal ribs may also be noted. The midrib is thick, and the lower edge of the
perforation at a considerable distance from the anterior margin.
Relations and Distribution—The size, the somewhat rounded back, and
especially the regularly nodose ornamentation, may serve to distinguish this from
any other species of Rimula in the Inferior Oolite. My specimens are all from
Stoke Lodge.

area constitute a tricarinate figure, whilst smaller ribs to the number of about
nine on each side occupy the flanks and posterior area. Extremely rich trans-
verse ornament pervades the entire shell. The perforation (incorrectly shown
in the apical figure) is at some distance from the anterior margin.
Relations and Distribution.—Differs from R. tricarinata, Sow, in being more
elevated, in the less square outline of the anterior margin, and in the stronger
character of the side ornaments. Two specimens from the ‘ base-bed,”’ Lincoln.
398. RIMULA SUBTRICARINATA, Sp. nov. Plate XLI, figs. 17 a, 17 b.
Description.—This is an extremely small shell, so that even approximate
measurements are difficult to obtain. Fairly elevated, with the apex curved so as
to slightly overhang the posterior margin; with three conspicuous anterior ribs,
of which the midrib is much the thickest, whilst the other two are thin and
divergent ; these constitute a tricarinate figure with a squarish anterior margin.
The sides and posterior part of the shell are thickly costated, and the whole
surface is marked with transverse lines, so as to produce a close and delicate
reticulation throughout. The perforation is fairly distant from the anterior margin.
felations and Distribution.—While evidently related, as regards its general
figure, to Lt. tricarinata, Sow., the ornaments in this species are much closer and
finer, also the two divergent anterior ribs are more slender. There are five
specimens in my collection from the Pea-grit of Leckhampton.

which the middle one is the most prominent; there are also slight traces of
smaller cost upon the flattened sides of the shell; the height exceeds the length
of the aperture; rare.”
This diagnosis agrees with the specimen in the Jermyn Street Museum,
although, according to my measurements, the height does not quite equal the
length of the base.
Relations and Distribution.—The relative height and compression may serve to
distinguish this from any other species of Rimula, though it is evidently related
to the species erroneously identified by Morris and Lycett (‘ Great Oolite Moll.,’ pt. i,
p. 87, pl. vii, fig. 3), with Rimula (Hmarginula) Blotii, Deslongchamps. The form
figured by Morris and Lycett has been referred with a query to R. Deslongchampsi,
Cossmann (‘ Et. Bath.,’ p. 342, pl. xii, figs. 33—34). Rinwla alta, as a species, is
based on a single good specimen from Leckhampton.
400. RiwuLa ooxrrica, sp. nov. Not figured.
This name I propose for the forms in the Inferior Oolite which several British
authors have referred, under the generic title of Rimula, to Emarginula Bloti,
Deslongchamps.’
Description.—Shell small, strongly tricarinate, sides much compressed and
flattened, and ornamented by seven or eight curved coste of considerable
prominence. ‘The two intercarinal grooves are narrow, and show no trace of an
intermediate rib. ‘Transverse scalate ornament pervades the shell. Other
indications clearly those of a imula and not of an Hmarginula.
Relations and Distribution. —Differs from R. tricarinata, Sow., in its narrow,
compressed, and elongated form: not so elevated as f. alta, which also possesses
somewhat different lateral ornamentation ; resembles the Great Oolite species
! Thus we find the following identifications :

Mons. Cossmann was probably one of the first to point out that the Jurassic
forms hitherto referred to Fissurella might with more justice be assigned to
Puncturella. I have already stated that no true Keyhole Limpet has been seen
by me from the Jurassic Rocks.

height a little less. The base is nearly circular, the apex subcentral. Radial
coste are numerous and close, and decussated by finer transverse lines, the points of
intersection being marked by small rounded granulations. The perforation appears
to be a little in front of the apex, and very narrow. The internal border or septum
is distinctly visible in the figured specimen.
Relations and Distribution.—These micromorphs from the Peagrit of Leck-
hampton possess such a general resemblance to Deslongchamps’ species that this
identification seems legitimate. There are four specimens in my collection, all
about the same size.

Bibliography, Sce.—Patella rugosa was originally described by Sowerby from
the Great Oolite of Minchinhampton, where it is extremely abundant, but for the
most part much worn, like many of the Minchinhampton shells. Hence the slight
spiral apex is in no case preserved in the Minchinhampton fossils. The species is
very much rarer in the Inferior Oolite, yet specimens from the Lincolnshire
Limestone, such as the one figured, do occasionally exhibit the capuliform apex.
Such specimens had been in my Collection for some years, when Herr Bohm
(op. cit.) was able to demonstrate that P. rugosa is in reality a species of Capulus.
Description.—The figured specimen has the following dimensions :
Length :; : ; . 44mm.
Width . 04mm.
Height , : : . 12mm.
CAPULUS. 459
Shell conical-depressed ; base oval, but slightly expanding anteriorly; apex
posterior with a slender spiral curve. The strong radiating ribs are closely
arranged and decussated by encircling growth-lines, which are crowded on the
posterior side, wide apart anteriorly. The actual apex is smooth, and presents an
extremely small spiral knot, but the radiating ribs commence at a very early stage
(figs. 2 a, 2D).
Relations and Distribution—Whether Capulus or Patella, this is by far the
most abundant limpet-like shellin the Jurassic rocks. P. Tessonii may be regarded
as a megalomorph from the ‘“ Oélithe ferrugineuse’’ of Moutiers, where the radial
coste are wide apart.
Capulus rugosus is certainly rare in the Inferior Oolite of this country.
It is quoted from the “‘roestone’”’ of Leckhampton Hill. Iremember also to have
seen a specimen of considerable size from an inland locality of the Yorkshire
Dogger. Though by no means abundant, it is better represented in the Lincoln-
shire Limestone than in any other beds of Inferior Oolite age, e.g. Stoke Lodge,
Ponton,and Weldon. Varieties of this species may also be noted in beds of later
age than the Great Oolite.

The Patellids of the Jurassic rocks have been described under several genera,

the Inferior Oolite of this country we do not possess many more than half a dozen
species, and these on the whole are scarce and locally distributed. In the absence
of special evidence these will be described primarily under Patella.

In specimens from the Great Oolite the figure is stated to be a more lengthened
oval, whilst the apex is somewhat more elevated.
Felations and Distribution.—Less orbicular and less conical than P. nitida ;
moreover, in this species, the convex side (not sufficiently convex in fig. 4a) is
the shorter. My best specimens are from the base of the Lower Freestones,
Leckhampton, where P. inornata is not uncommon. It also occurs in the North-
ampton Sand at Duston, and in the Lincolnshire Limestone at Stoke Lodge.

Morris and Lycett (‘ Great Ool. Moll.,’ pt. i, p. 88) refer certain shells from
the Cotteswolds to Miinster’s species. ‘Their figures are not satisfactory ; and, as
P. cingulata is an Upper Jurassic form, Cossmann (‘ Ktage Bathonien,’ p. 354)
suggests that the Great Oolite forms may represent a different species.
There are two specimens in the Jermyn Street Museum from the Inferior
Oolite of Rollwright Heath, in Oxfordshire, which is very high in the series. In
their depressed outline these specimens more nearly resemble the figures of
Goldfuss than those of Morris and Lycett. The principal resemblance, however,
is in the striated growth-lines (fig. 5c), thus producing a marked concentric
ornamentation.

The base is roundly oval, with a perfectly smooth edge. The surface is smooth,
but with a strong lens it is possible to discern very faint concentric lines.
Relations and Distribution.—The points wherein P. nitida differs from
P. inornata have been already indicated. P. nitida is stated by Deslongchamps to
be common in the Bath Oolite of Normandy, whereas at Minchinhampton it seems
to be represented only by P. inornata. Scurria nitida is quoted by Dr. Glangeaud
(‘ Le Jurassique 4 l’ouest du plateau central,’ p. 119) from beds of Bajocian age.

Bibliography, §c.—Sowerby’s enlargement of his P. nana from Ancliff repre-
sents a more oval shell than the one now figured. Morris and Lycett figure a
more conical form with almost central apex, and this is the prevailing form at
Minchinhampton and Bussage. It is just possible that Sowerby’s species may be
different.

Specimens from the Lincolnshire Limestone are rather smaller and less peaked than
some of those from the Great Oolite of Minchinhampton. Under certain conditions

occur at the points of intersection. Margin thickened.
Relations and Distribution—This form seems to stand alone amongst the
Patellids of the Lower Oolites. The nearest described species of Jurassic age
appears to be P. sulcata, Deslongchamps (‘ Mém. Soc. Linn. Norm..,’ vol. vii, p. 115,
pl. vu, figs. 9 and 10), from the Inferior Oolite of Port-en-Bessin. But even this
species differs widely. On the other hand, its resemblance to the more elevated
varieties of the existing Patella vulgata are quite startling.
A single specimen has been found by Mr. Windoes in the Chipping Norton
Limestone, which overlies the Clypeus-grit in the neighbourhood of that town.
This may be regarded as the highest horizon of the Inferior Oolite.

Mr. Brodie’s collection of fossils from the Leckhampton freestones has been
acquired for the Jermyn Street Museum. There are two specimens purporting
to be Patella retifera, besides specimens of Fissurella Brodiei, which latter is a
closely allied, if not identical form, ina somewhat different matrix. The labels
are not in Lycett’s handwriting.

““Ovate, costated, and cancellated; coste numerous and unequal, crossed by
numerous encircling lines; apex moderately elevated, posterior, but inclined
forwards.”
The so-called Fissurella Brodiei exhibits the same characters, but is a slightly
narrower shell.
felations and Distribution.—Both radial and concentric ornaments of this
extremely pretty little shell are very sharp, and this serves to distinguish it from
Patella (Guerangeria) clypeola, Deslongchamps, a Bathonian species, where the
radial ornamentation only is in evidence. There is something peculiar in the
character of the apex, which seems to indicate that it may not be a Patella in a
strict sense, though none of the specimens could be placed under Fissurella.
There are about half a dozen specimens in the Brodie Collection from the
Leckhampton freestones, which contain a shallow-water fauna.

N.B.—The fossil Opisthobranchiata have lately received a large share of
attention in M. Cossmann’s admirable work ‘ Hssais de Paléoconchologie comparée ’
(Premiére livraison, Fevrier, 1895); and still more recently in his splendid
Monograph, ‘ Etudes sur les Gastropodes des Terrains Jurassiques,’ now in course
of publication in the Memoirs of the Geological Society of France. This author
greatly favours the subdivision of families and genera. Thus we find the
following families enumerated from the Jurassic rocks,—Actzonidex, Tornatinide,
Bullide, Aceridze (nov. fam.), and Aplustride. M. Cossmann also includes
Ceritella and Fibula amongst the Opisthobranchiata under Tubiferidee (nov. fam.).
The genera and sections are also largely multiplied. Without in the slightest
degree questioning the scientific value of these subdivisions, it is proposed to group
the Opisthobranchiata of our Inferior Oolite, for present purposes, under the
families Tornatellide (Acteeonide) and Bullide.
Family—TORNATELLIDA (Actmonipa).
“ Shell external, convoluted, ovoid, conoidal, spire depressed or prominent ; whorls
tolerably numerous, without internal absorption, aperture entire, narrow.’’—FIscHER.
N.B.—The following genera, subgenera, and sections of this family are
recognised by M. Cossmann as occurring in the Inferior Oolite, viz. Tornatellea,
Conrad (e.g. J. pulchella, Deslong.); Acteonina, @Orbigny (e.g. A. gigantea,
Deslong.) ; Striactwonina, nov. sect. (e.g. Act. Sarthacensis, d’Orb.). Cylindro-
bullina, von Ammon (e.g. Act. Scarburgensis, Lycett; Cylindrites, Morris and
Lycett (e.g. Acteon acutus, Sowerby).
Trochactzonina, Meek, is also quoted from the Bathonian (e.g. Act. ventricosa,
d’Orbigny, and Cassis Esparcyensis, d’ Archiac).
In the present instance it is proposed to retain the older generic classification
of the Tornatellide of the Inferior Oolite, whilst indicating as far as possible the
equivalents under the new system. Tor the most part the specimens are not
sufficiently well-preserved to show the finer points,

notched at the base.

Bibliography, §c.—Deslongchamps described this species as having three
columellar folds, though it might require an exceptionally well-preserved specimen
to show them. He justly hesitated to make a new genus. D’Orbigny placed it
with doubt under Actxonina, considering that the folds indicated by Deslongchamps
might bring it within the range of Actxon. The species is not quoted as British
either by Morris or by Hudleston and Wilson.

Shell oval, apex acute. Number of whorls six, sub-tumid, with the posterior
edge more sloping than tabulate. The spiral striz are close, deeply cut and
punctate, the sloping shoulder of the whorls exhibiting a special form of grooving,
whilst the spirals in the upper portion of the whorls are wider apart. Aperture
sub-elongate, elliptical, with a very short columella; this has evidently been
marked with oblique folds, but it is not easy to say whether two or three;
indications of an anterior notch.
Relations and Distribution —This form obviously differs from Acton pulchellus
in its more slender shape, in the comparatively sloping posterior margin of the
whorls, and especially in the general closeness of the spiral striz. It is near to
Tornatellea multistriata, Rigaux and Sauvage, and also resembles Tornatellea
Brasili, Cossmann, which is described from the Bajocian of France.
The finest specimens of Actxon ooliticus occur in the Concavus-bed at Bradford
Abbas. Stoford and Horton Hill have also yielded specimens, which bear
considerable resemblance to the Bradford Abbas forms. When the folds on the
aperture have been effaced, it might be difficult to distinguish this species from
Actzonina pulla, K.and D. There is a very slender variety with five whorls from
the ‘* Base-bed,” Lincoln, ? a distinct species.

The following is Lycett’s diagnosis :—‘‘ Small, turrited ; whorls few, long,
nearly flat, each with three encircling striz, equidistant; the body-whorl has six
striz besides numerous others closely arranged at the base.”’
468 GASTEROPODA OF THE INFERIOR OOLITE.
The figured specimen has the following dimensions :—Height 10 mm., spiral
angle 45°. The number of whorls five ; aperture sub-elongate, elliptical, with a short
columella, which has folds and anterior notch somewhat reflexed.
Relations and Distribution.—Lycett’s type is smaller than the figured specimen,
and ill-preserved, but there is sufficient of the aperture remaining to show that it
belongs to this section of Actzon (Tornatellxa) : it was obtained from the Free-
stones of the Cotteswolds—Murchisonx-zone. ‘The figured specimen is a larger
shell, and was obtained from Drympton (most probably Opalinus-zone).
This species comes very near to Tornatellea inequistriata, Cossmann, from
the Murchisone-zone of the Meurthe.
Besides the three species of Actxon (Toinatellea) described above, there are
two other species or varieties: viz. a form in the Opalinus-bed, Drympton,
resembling but not identical with Acton pulchellus; secondly the narrow form
from the ‘‘ Base-bed,” Lincoln, provisionally classed with Actxon ooliticus.
Genus—Actrmonina, @ Orbigny, 1850 (= Orthostoma, Deshayes).
* Shell oval or fusiform ; spire salient, but shorter than the last whorl, which is
angular in the vicinity of the suture ; aperture elongated, narrow, entire, not sinuous ;
outer lip simple, sharp; columellar lip curved; columella thick, but smooth.”’—
FIscHER.
There is nothing in this diagnosis with reference to sculpture, but one might
add ‘‘ smooth or striated.” The above is a somewhat generalised diagnosis, which
would include the sections previously mentioned.
The genus Actxonina is interesting to the paleontologist as perhaps the oldest
member of the Tornatellide, the section, Cylindrobullina, dating back from
Carboniferous times. It is best represented in the Jurassic period, and, according
to d’Orbigny, the maximum development of the genus was attained during the
deposition of the Lower Lias. As regards distribution in the Inferior Oolite of
this country, the several horizons in Yorkshire have yielded a considerable
number of species, the Lincolnshire Limestone and the Inferior Oolite of the
Cotteswolds are also accountable for several species, whilst the Dorsetshire beds,
usually so rich in Gasteropods, have not yielded many species of Actxonina.
We may admit that Actxonina is an inconveniently large genus, including
forms of somewhat diverse character, both as to shape and ornamentation. As
regards ornamentation merely, we might divide the Actzeoninas of the Inferior
Oolite into three groups:
1. Actxoning with deep spiral grooving and a general resemblance to Acteon
ACTAONINA. 469
(Tornatellea), but with no proved columellar plication. This group includes such
forms as Auricula Sedgvici and Tornatella pulla, which I have hitherto classed with
the Actzeons, as indeed have most authors, though Tate referred Tornatella pulla,
K. and D., to Actxonina.
2. Actxonine with fine spiral lines (Striactxonina in part) such as Acteonina
Sarthacensis, d’Orbigny. Possibly also Acteonina humeralis, Phillips, which has a
strongly impressed line on the shoulder, might come in here.’
3. Actxonine which are perfectly glabrous, or only exhibit striation, more or
less faint, towards the anterior extremity. This division would include, amongst
others, Actxonina as limited, and the sections Ovacteonina, Cylindrobullina, and
Trochactzonina.

Bibliography, §c.—Owing to imperfect preservation it is still doubtful whether
Phillips’ species is an Actxon or a striated Actxonina. ‘In the few cases where
the aperture has been visible it is invariably without plication”? (Hudleston,
loc. cit.). Brauns (‘ Mittlere Jura,’ p. 194) considered Tornatella pulla, K. and D.,
the same as Actxon pullus, Morris and Lycett, but different to Awricula Sedgvici,
Phillips.
Description.—From 5 to 10 mm. in height and considerably more than half as
wide as high. Ovate, with a stumpy spire composed of about three whorls. The
whorls are strongly tabulate. The body-whorl and penult are ornamented by
deeply-cut spiral striz, which are but slightly punctate; the surface of the
body-whorl is thus divided into a number of strap-like belts, of which two,
situated slightly below the middle, are wider than the rest. Other indications
wanting.
Relations and Distribution—A stumpy form almost peculiar to the Dogger,
! Stoliczka remarked that the ‘surface of many Actxonine appears to be perfectly smooth, but
it is more likely this is only in consequence of the uppermost punctated layer of the shell having
been removed” (‘ Cretaceous Gastropoda of Southern India,’ p. 399).

Description.—Morris and Lycett say :—‘‘ Shell ovate, spire elevated, somewhat
acute; whorls (six) convex, the last whorl sub-cylindrical; aperture ovate; the
surface with numerous regular punctated encircling strie.” The above descrip-
tion refers to specimens either from the Millepore-bed or the Scarborough Lime-
stone.
Relations and Distribution.—More elongated and oval than Actxonina Sedgvici,
and probably a more widely distributed form. I have specimens from the
Scarborough Limestone of Scarborough Bay which are rather stouter than Morris
and Lycett’s type. <Actxonina (Actxon) pulla also occurs in the Lincolnshire
Limestone at Weldon, and in the Inferior Oolite of Hook Norton (Walford
Collection). These are all specimens without folds on the columella. But it is
quite possible that, in some instances, imperfectly preserved specimens of Acteon
(Tornatellza), suchas Actxon ooliticus, are set down to Koch and Dunker’s species.
In this way Actxonina (Actzon) pulla is a convenient name for any small and
badly preserved specimen of the striated Tornatellide.

on the posterior margin, which is marked by animpressed line. Body-whorl about
twice the height of the spire. The texture of the shell is smooth with very fine
striations, which have a tendency to become effete towards the centre of the body-

whorl (fig. 16 a), but are well marked where the anterior compression commences.
Aperture ovate-elongate with a thin straight outer lip and a smooth columella.
Telations and Distribution.— Differs from Actxonina pulla in the fineness of
the striations, though, if we accept the view of Stoliczka, this may be somewhat a
matter of preservation. Resembles Actxonina sparsisulcata, d’Orbigny (‘ Terr.
Jur.,’ 11, p. 166, pl. 285, figs. 14 and 15). This form occurs in the Lincolnshire
Limestone at Weldon, in the Parkinsoni-zone of Burton Bradstock, and in the
Cadomensis-bed at Oborne.
Since I do not venture to constitute this as a distinct species, it may be
regarded as a possible variety of Actxonina pulla.

Shell cylindro-conical; the spire occupies about one fourth of the total height,
and consists of five or six whorls, which are cylindrical with tabulate posterior
margin, except towards the very sharp apex, where they are slightly convex. The
entire shell is pervaded by fine and close striato-punctate ornament. There is a
strongly impressed line on the posterior margin of the whorls, and a somewhat
finer line on the flat area between the margin and the suture. The body-whorl is
a narrow cylinder much compressed anteriorly ; aperture ovate-elongate with a
smooth columella.
Relations and Distribution.—This may be regarded as a narrow represeutative
of Acteonina Sarthacensis ona lower horizon. (Cossmann says that A. Sarthacensis
isreally a Bathonian species, and not Bajocian as represented by d’Orbigny.) On
the other hand, if we accept the suggestion of Stoliczka as regards striation in the
Tornatellidee, Acteonina tenuistriata may be nothing more than a different mineral
condition of Actxonina humeralis. This was the view I took in 1885. There are,
however, certain slight differences of shape which favour the notion of their being
distinct species.

Shell cylindro-conical; the spire about three-tenths the total height, and
composed of five whorls. In many respects the description of the preceding
Species is applicable to this one. ‘Thus the whorls of the spire are flat atop and
marked on the shoulder by a grooved line, which produces two steps, or a sort of
double tabulation. ‘he grooving on the shoulder is very distinct in the body-
whorl, which is perfectly cylindrical. But there are no traces of spiral striation,
except some faint lines towards the anterior extremity. The length of the
aperture is about two-thirds the height of the shell: it is narrow behind, wide in
front; outer lip straight and thin, columellar lip smooth and without plications.
Relations and Distribution. Acteonina humeralis is not uncommon in the
Yorkshire Dogger, though good examples are scarce. Many specimens also are
much smaller than the one figured.
A narrow and perfectly glabrous variety occurs in the Concavus-bed at
Bradford Abbas. My ‘‘ MS.” name for this variety is “ swb-hwmeralis.’’ This
passes by degrees into a distinct form.

Shell oval-elongate. Total number of whorls six, the spire occupying from
three to four tenths of the entire height. The apex is slightly obtuse. The
whorls are subconvex, with a narrow posterior ledge indented by a deep groove;
sutural angle oblique. The body-whorl is very ovate, and like the rest of the
shell perfectly smooth, growth-lines alone being visible. The aperture is oval-
elongate, and about half the height of the entire shell. There is a considerable
incrustation on the columella, which is only slightly sinuous.
Relations and Distribution —The peculiar ovate-elongate character of this shell
and the convexity of the whorls forcibly remind us of Acteonina Loriereana, d’Orb.,
which may be regarded as a typical Ovactxonina. On the other hand, the grooved
ledge on the posterior margin of the whorls, although very narrow, serves to
remind us of Striactxonina.

Relations and Distribution.—Acteonina glabra possesses the most stumpy
spire of all the truly cylindro-conical Actxonine (Cylindrobullina). In Yorkshire
it occurs chiefly in the uppermost horizon of the Inferior Oolite. I have a
specimen in my Collection from the Dean and Chapter Pit at Lincoln (Murchisone-
zone) 22 mm. in height. On the higher horizons of the Lincolnshire Limestone at
Wansford and Weldon, and also at Barnack, smaller specimens like fig. 22, and
still smaller ones, are by no means rare.

considered a broad variety with a somewhat higher spire and more distinct

Bibliography, §e.—The Normandy specimens (Bathonian) are mainly casts.
The very large specimens from the Inferior Oolite of the Yorkshire coast are
broader than the French types. ‘This is one of the few species for which the
generic name, Actxonina, is retained by M. Cossmann.
Description.—The specimens from our Inferior Oolite are variable as to size
and shape. The Yorkshire specimen figured by Morris and Lycett has a height
of 40 mm., whilst the specimens figured in the accompanying plate do not exceed
25mm. ‘The spiral angle may be said to range from 52° to 60°, whilst the body-
whorl is generally less than two-thirds the total height.
The shell is oval, thin, and smooth, whorls (seven or eight) rather flattened at
the sides, sub-convex, with the posterior tabulation slightly rounded off ; aperture
narrow above, dilated below, and about three-fifths the entire length.
Relations and Distribution.—This may be taken as an average representative
of the genus Actxonina, closely related to the cylindro-conical forms (Cylindro-
bullina), yet passing by protraction into such forms as Actxonina acuta, VOrb.
Besides the Yorkshire specimens, there are some from the Parkinsoni-zone
of the Cotteswolds (fig. 2), which are rather short in the spire and approaching
Act. Scarburgensis. This variety of Act. gigantea I have noticed on several
horizons and localities of the Inferior Oolite; it is an intermediate form.
Fig. 3 from the Dean and Chapter Pit at Lincoln (Murchisonx-zone) may be
taken as a small but more typical representative of the species; whilst in Fig. 4
(specimen also from Lincoln), where the spiral angle is reduced to 45°, we have
the variety attenuata, which might almost be regarded as a distinct species.

Description by Morris and Lycett.—‘‘ Shell small, spire depressed, volutions
very narrow, rounded, their sutures deeply depressed ; the last whorl gibbous,
aperture an elongated oval. ‘This species is shorter than any other with which
we are acquainted.” The height of the type is about 10 mm. and the spiral
angle 100°.
Fig. 5 represents the specimen from the Bean Collection at the British Museum,
which is believed to be the Yorkshire type, though somewhat different to the
figure given by Morris and Lycett. It is obviously much broken away anteriorly.
Lycett had previously described the species from the Inferior Oolite of Gloucester-
shire, but no specimensare forthcoming. Very rare in the Scarborough Limestone
of White Nab.
Vig. 9, representing a small Tvrochactzonina, may possibly be the same species
with the anterior portion of the aperture preserved.

A single specimen from the Lincolnshire Limestone of Weldon, though only a
micromorph 10 mm. in height, has considerable resemblance to this well-known
Bathonian species. The spire is even more depressed than in Actexonina tumidula,
whilst the body-whorl] is broader atop and more pyriform in outline.

1859. Acrmontna antigua, Lycett. Cotteswold Hills, p. 125, pl. iv, fig. 9.7
Description.—The height of the figured specimen is38mm. Shell oblong, thin,
with an obtuse apex and short spire of about four or five volutions; the spire is from
one sixth to one seventh of the total height; whorls rounded upon their upper
borders. Aperture elongate, narrow above and expanded anteriorly; columella
curved and emarginated at its base,
The above is a slight modification of Lycett’s original diagnosis.
felations and Distribution—The proportions bear some resemblance to those
of Actxonina glabra, though in this case the spire is shorter and the figure of the
body-whorl is somewhat different. The type is from the Spinosa-stage of Rod-
borough Hill, and is the only specimen of that size which has come under my notice.
Smaller specimens, when compared with Actxonina glabra, exhibit a shorter spire
than that species.

1857. ActTmonina convo1uTa, Lycett. Cotteswold Hills, p. 125, pl. iv, fig. 8.
Description.—The height of the figured specimen is 35 mm. ‘‘ Shell oblong,
rather compressed at the sides; spire depressed, scarcely produced, consisting of
five volutions, which embrace each other and rise but little above the body-whorl ;
apex obtuse; aperture lenethened, very narrow above, more expanded towards
the base; columella curved at the base, emarginated and slightly twisted.”
Relations and Distribution.—The tendency of Actzonina in the direction of the
Bullidze seems to reach a maximum in this curious form. As pointed out by
Lycett, it differs from Bulla primeva, Deslongchamps, in its more cylindrical
figure and in the fact that the spire is slightly prominent, and not sunk in an
apical cavity.
The type is from the Spinosa-stage of Rodborough Hill. I have a character-
istic specimen from the Clypeus-grit of Aston Farm, and a smaller one from the
Rag of Cleeve Hill, allin the Parkinsoni-zone. In these specimens the outer lip is
straighter than in the figured specimen, which in this respect is rather mis-
leading.

478 GASTEROPODA OF THE INFERIOR OOLITE.
Genus—Cy.inprites, Morris and Lycett, 1851.
* Shell smooth, sub-cylindrical, or ovate; spire small; whorls usually flattened,

This is chiefly a genus of the Great Oolite; the number of species in the
Inferior Oolite is limited, and their distribution very partial. Considerable
difficulty arises from the uncertain evidence with regard to the identification of
Lycett’s species from the Inferior Oolite of Gloucestershire. On the whole the
species of Oylindrites may stand thus:

Description.—* Shell elongated, subcylindrical; spire lengthened, its apex
acute; whorls convex, their sutures deeply excavated, the last whorl ovately
cylindrical ; aperture narrow.” Lycett’s type is not available, nor have I seen a
specimen so large as the one figured by him. My specimen (fig. 12) has a spiral
angle of 60°, and no more than six whorls; the spire is nearly one third of the
total height.
Relations and Distribution.—Probably only a small variety of Cylindrites altus,
Morris and Lycett, from the Great Oolite, but less cylindrical, and with the
posterior edge of the whorls less flattened. Rare in the Lincolnshire Limestone
at Ponton and Weldon, it is the only species of Cylindrites from the Inferior
Oolite which has a well-developed spire.

Description.—Height 8 to 10 mm. and about two and a half times as long as
wide; the shell is cylindro-conical, with a short conoidal spire, consisting of about
six whorls which are narrow and step-like, with sharp edges. The body-whorl is
flattened and attenuated towards the base. The posterior portion of the aperture
is extremely narrow, and the twist on the columella not very strongly marked.
Relations and Distribution.—The strongly step-like character of the spire-whorls
is a characteristic feature. Rare in the Inferior Oolite at Leckhampton.
430. CYLINDRITES BREVISPIRA, Sp. nov. Plate XLIII, figs. 17 and 18.
Description.—Height 6°4 mm., width 4mm. Shell sub-cylindrical, wide at top
and much narrowed towards the anterior extremity. The spire is very low, but
the margin of each spire-whorl projects slightly beyond the margin of the body-
whorl, so that the figure of the spire is that of a very depressed, though regular
cone. There are about six whorls in all, the margin of each presenting a sharp
upturned edge with a slight hollow between. The body-whorl is pyriform.
Relations and Distribution.— Differs from Cy. attenwatus in its pyriform rather
than cylindrical shape, its greater proportional width, and in having a still more
depressed spire, whose whorls also are less flattened. Bears some resemblance to
Cy. bullatus, Morris and Lycett, but in that species the spire is sunken.
There are five specimens in my Collection from the Lincolnshire Limestone of
Weldon.

480 GASTEROPODA OF THE INFERIOR OOLITE.
Bibliography, Sc.—The type is preserved in the Jermyn Street Museum. It
cannot be said to correspond very closely with Lycett’s diagnosis.
Description.—(Based upon the specimen in the Jermyn Street Museum.)
Height 17 mm., width 9 mm. Shell cylindrical, but tapering anteriorly. The
spire, consisting of about five whorls, is nearly flat and slightly sunken, but with a
prominent mammilliform apex of considerable size. The posterior margin of the
body-whorl is flattened and encloses the spire, the dividing suture lying in a deep
eroove. The columellar lip is strongly twisted.
The var. Weldonis is a fossil of much smaller habit, the usual height being
8mm., width 4mm. It is also somewhat more pyriform in figure.
Relations and Distribution.—Belongs to the section of COylindrites which have
sunken spires. Differs from Cy. mammillaris in the extensive flattening of the
posterior margin of the body-whorl, and in the groove which divides this from
the spire-whorls ; it is also rather broader in proportion to its length.
The specimen in the Jermyn Street Museum, from the Inferior Oolite of
Nailsworth, is the only one I have seen from the Cotteswolds. The var. Weldonis
is the most abundant Cylindrite in the Lincolnshire Limestone at Weldon and
Ponton.

Description.—Height 20 mm., width 8 mm. in a good-sized specimen. Shell
cylindrical, elongate, sharply truncated atop. Spire flattened and sub-depressed,
but the inner whorls have their upper flat surfaces visible, the first two or three
of which are rounded into a mammillary knob. Aperture elongate with a strong
columellar fold.
Relations and Distribution.—This is an extremely narrow and cylindrical form,
only differing from Cy. cylindricus, Morris and Lycett, in the salience of the
mammillary knob and in the flattening, rather than depression, of the spire.
There are two specimens of Cy. mamivillaris in the Brodie Collection from the
Leckhampton Freestones. A variety, approaching Cy. cylindricus, also occurs
sparingly in the Lincolnshire Limestone of Weldon. This has been quoted as
Cy. cylindricus.

Shell ovate, ventricose or pyriform, summit contracted, and partially concealing
the inner whorls, the first of which is slightly elevated. The columellar lip is
drawn out anteriorly and sinuous. Aperture widely ovate anteriorly, and but
moderately contracted posteriorly.
Relations and Distribution.—The mammillary apex and extension of the
columella easily serve to separate this shell from Bulla wndulata, Bean. Indeed,
they may be generically distinct. A single specimen from a high horizon in the
Spinosa-stage near Avening, a village not far from Minchinhampton.

Durine the period that the Monograph on the Inferior Oolite Gasteropoda has
been in course of publication, a certain number of specimens have been noticed or
procured too late to be recorded in their proper places. They are mostly rare
forms, and in some cases the genus is doubtful. These it is now proposed
somewhat briefly to describe, in most cases with a figure. See Plates XLIII and
XLIV.
436. PURPUROIDEA, species. Plate XLIV, fig. 9.
A single fragment of a large Purpuroidea was recently obtained from the
Lincolnshire Limestone at Rauceby. There is not enough material to constitute
a species, but the circumstance is interesting from its being the only instance of
Purpuroidea as yet recorded from the Inferior Oolite of this country.
Though apparently differmg from any of the Great Oolite species, it most
nearly resembles P. Morrisea, Buvignier, which is the common form at
Minchinhampton. Possibly also some of the Corallian species described by
Buvignier, such as P. Moreana, may be near.

from the Leckhampton Freestones has been acquired for the Jermyn Street
Museum, <A specimen marked ‘ Turbo, n.sp., 34,” answers fairly well to Lycett’s
description, so far as the whorls of the spire are concerned. This is evidently a
Purpurina, and has some resemblance to the form on Pl. I, fig. 2, of this

The body-whorl is large and bicarinate owing to the prominence of the second
and third spirals; number of spirals in the base about five.
The aperture is quadrangular with the columella considerably produced and
slightly curved, and terminated at the point by a conspicuous reflexed notch
or gutter.
Relations and Distribution.—This curious shell has a strong resemblance to
Iittorina Phillipsii, except as regards the aperture. A single specimen from

Shell sub-fusiform ; apex sharp; spire regular; number of whorls eight,
sutures close fitting. The ornaments consist of wide-apart longitudinal varices,
which are decussated by strong spiral lines, slightly nodular.
The body-whorl is considerably expanded so as to make the outer lip patulous.
The longitudinal varices are scarcely to be traced in the body-whorl, which is
ornamented by numerous spiral ribs, expanding outwards with the increase of the
whorl and causing the margin of the lip to be crenulate. The aperture is oblique
with a full and rounded outer lip, somewhat flattened anteriorly, with a sinuous
and rather encrusted columella, which terminates in a broad, short notch turned
outwards almost at right angles to the axis of the shell.
Relations and Distribution.—This form is very different to the general facies
of the shells in the Inferior Oolite which have been referred to Cerithium. It is
suggestive of Pyrazus and other sub-genera of Potamides, but these are at least
brackish-water shells. On the other hand, its resemblance to such shells as
Cerithium (Colina) contractum, Sow., and Cerithiwm (Colina) teniatum from the
Indian Ocean (Natal) is very striking. Provisionally we may refer the Oolite
specimens to Colina. Mr. Wilson considers that, possibly, there is a generic
affinity between C. Lycetti and the Upper Lias Nortonia Patroclus.
From Nailsworth (Oolite Marl or Pea-grit) there are four specimens in the
Jermyn Street Museum (Lycett Collection). The figured specimen is the most
elongate.
441. Bracnytrema, sp. Plate XLIII, fig. 23.
An imperfect specimen with an estimated height of 15 mm. and a spiral angle

with an effuse outer lip; columella much twisted near the base, with a broad
gutter or notch directed outwards at an angle of 45°. There is strong granu-
lated spiral ornamentation throughout the shell, which appears to have been
very thick.
This seems to be a typical Brachytrema. A single specimen from the Irony
Nodule-bed, Burton Bradstock.

and is somewhat bicarinate. All the whorls, including the body-whorl, are
slightly convex and very smooth. The aperture is quadrate, with a short thick
columella, and wide anterior notch. A fold on the inner and outer walls of each
whorl.
Relations and Distribution.—This species belongs to the biplicate section of
Nerinella (see p. 198, and Pl. XIII, figs. 1 and 2, of this Monograph). It is much
broader than either of the two unnamed forms there described. Consequently the
shape of the whorl in section is much more squat.
There are two specimens in my Collection from the Lincolnshire Limestone of
Weldon, and others which seem to connect with the narrower forms.
447, Nurinma (Pryematis) cf. cincenpa, Phillips. Plate XLIV, figs. 8, 8a, 8b.
Specimens of an elongate Nerinxa, not unlike N. cingenda, occur somewhat
plentifully in the Lincolnshire Limestone at Stoke Lodge. In this case the
internal section is that of a Ptygmatis with five folds. The specimens greatly
resemble a variety provisionally named ‘‘ pseudocingenda” (see p. 212, Pl. XIV,
fig. 15, of this Monograph). Bearing in mind that sections of Dogger specimens
of Nerinea cingenda are liable to mislead, the Stoke Lodge fossils may possibly
represent the true internal structure of this species.
Genus—Patupina, Lamarck, 1812.
Shell turbinated with round whorls, thin; aperture circular, slightly angular
behind, peristome continuous, entire ; operculum horny, concentric.
Conchologists have expressed a doubt whether Paludina extends as far back
as the Jurassic. Yet Paludina occurs abundantly in the Upper Purbecks.
Neither can we doubt that Paludina scotica, Tate (‘ Quart. Journ. Geol. Soc.,’
vol. xxix, p. 349, pl. xii, fig. 3), from the Infra-Oxfordian beds of Loch Staffin, |
is correctly referred to that genus.

umbilical furrow. Number of whorls five to six. These are very tumid and
separated by a deeply impressed, almost canaliculate suture; sutural angle very
oblique. No ornamentation, other than growth-lines, which are rugose and
varix-like on the body-whorl. Aperture nearly circular with thin sharp lips.
Relations and Distribution.—This species resembles in some respect Paludina
scotica, which occurs in the Hebrides on approximately the same horizon. It also
differs but little from Paludina vivipara, being perhaps of smaller habit and with
amore sloping sutural angle and more convex whorls than the existing species.
On the other hand the Paludinas of the Upper Purbeck are for the most part
very different.
Paludina Langtonensis is abundant in the so-called Paludina-bed, a kind of
mortar-like deposit which occurs high up in the Chipping Norton lmestone at
Langton Bridge, along with other freshwater species and occasionally seeds of
Chara, &e. But associated with these are species of Cerithium and Nerinea along
with a small variety of Amberleya nodosa—apparently a Bathonian fauna. This
deposit, where developed, is found to underlie a gritty bed containing teeth and
palates of fish. :
Paludina Langtonensis also occurs in great abundance at Castle Barn, three and
a half miles from Chipping Norton, and traces may likewise be seen at Sharp’s
Hill in a similar position.
Genus—Vatvata, Miller, 1774.
Shell wmbilicated, turbinoid, or subdiscoidal, spire but slightly prominent, whorls

expanded.

The transverse diameter of these little shells does not exceed 3mm. Judging
from the figure they differ slightly from Valvata precursor, Tate (‘ Quart. Journ.
Geol. Soe,’ vol. xxix, p. 348, pl. xii, fig. 9). The spire is more salient than in
Valvata cristata.

The following is Lycett’s diagnosis. ‘‘ Very elevated; whorls few, concave,
with longitudinal elevations united at the base, and overwrapping the upper
portion of the succeeding whorl, base discoidal.’’ Further on he adds that this
will probably be erected into a new genus.
There is a single specimen in the Brodie Collection, the apical whorls alone
being preserved. It is clearly a species of Onustus, related to O. acuminatus,
Hudl. There are two much larger specimens, also from the Cotteswolds, which
have been in the Jermyn Street Museum for some years (see p. 328, supra).
These may be referred to Onustus pileus, Lycett.
452. DetpHinuta or Margarita, species. Plate XLIV, figs. 3a, 3.
This form has considerable resemblance to Delphinula (Turbo) Santonis, Hudl.,
differing principally in details of ornamentation. At the same time I would
scarcely refer to it as absolutely the same species.
A single specimen, said to come from Cold Comfort in the Cheltenham district.

Club, vol. i, p. 77.
This is a doubtful species, since the two specimens thus marked in the Brodie
Collection differ in more than one respect from the diagnosis, which is as follows :—
‘* Subglobose, spire of several whorls, angulated ; longitudinal coste large, elevated,
rather angular, impressed by numerous transverse (spiral) lines; umbilicus
costated ; aperture orbicular.”
SUPPLEMENT. 491
CHILODONTOIDEA, genus nov.
Shell short, thick, eucycloid, slightly pupeform, imperforate. Whorls irregular,
the anterior ones carinate ; body-whorl considerably shorter than the spire ; ornamen-
tation subreticulate. Aperture externally quadrate and oblique, witha double callosity
on the columella, which is dentate at the angle; a broad callosity inside the outer lip
further restricts the aperture internally.
There are many points of resemblance between this curious genus and Chilo-
donta, Etallon, which, however, is represented as having five internal teeth or
ceallosities. ‘The Corallian genus also has a more distinctly trochiform spire,
though the character of the ornamentation is somewhat similar. Fischer (* Manuel,’
p- 818) makes Chilodonta a sub-genus of Clanculus, one of the Trochide. In this
connection the following references may be useful.

Description :
Height : ; 9 mm.
Body-whorl to total height : : se dsc LOO!
Spiral angle irregular and convex.
The apex is sharp; number of whorls eight, flat to subconvex in the early
stages, strongly carinate in the later ones, and separated by a deep suture. The
ornaments in the upper part of the whorls consist mainly of delicate and rather
sinuous axial lines, which on the keels produce a fine granulation ; in the anterior
portion of the whorls the ornaments are chiefly spiral. The shell gapes somewhat
between the penult and body-whorl, which latter is stumpy, and towards the
aperture its upper margin encroaches on the penult. The body-whorl is carinate
and spirally ornamented on the base. There are, however, considerable differences
in ornamentation according to locality.
The characters of the aperture are those of the genus.

clathrata have already been partially indicated. Attention is also drawn, in
the accompanying footnote, to another form, lately found in the Lias of Thorn-
combe, which evidently belongs to the same group, though generically, or at least
subgenerically, distinct.’
Chilodontoidea oolitica is a rare species, yet it occurs on the same horizon at
four localities, viz. the Concavus-bed at Bradford Abbas and the Irony Nodule-bed
of Burton Bradstock; also at Beaminster and Stoford.

Description :
Height é x . komm:
Body-whorl to total fest , : 2 Or L0G:
Spiral angle . , 60°.
An ovate elongate shell with a accil spire sad few suede which are non-
embracing. A. very slight umbilical fissure. The entire shell is ornamented with
strong spiral ribs, regular and equidistant. Aperture a lengthened oval, with an
arched and crenulated outer lip, expanded anteriorly, and a long and almost
straight columellar lip. ‘The entire peristome is thick.
Relations and Distribution.—There is very little difference between this shell
and the existing Couthouya reticulata, A. Adams, from the China seas. The
modern shell has a better developed umbilical fissure, and is rather smaller ; Isapis
fenestrata, Carpenter, from the west coast of North America, is also very near.
A single specimen from the Concavus-bed, Bradford Abbas.
1 Tn order to find a place for the Lias shell, I propose to constitute the genus Wilsonia, thus
named in honour of Edward Wilson, Esq., F.G.S., Curator of the Bristol Museum, who is our chief
authority on the Gasteropoda of the Lias. The following is the diagnosis :
Shell small, very thick, irregularly pupxform, imperforate, whorls increasing irregularly and scarcely
convex, separated by a distinct but rather narrow suture. Ornaments pronounced, consisting of four or
five granular spiral belts in each whorl, with fine intermediate axial decussation. Body-whorl rather
shorter than the spire and compressed. Aperture sub-circular, with a thick outer lip and two prominent
teeth towards the middle of the short columella.
Wilsonia liassica, sp. nov. (Plate XLIV, figs. 13 a, 136, 13 c), has seven or eight whorls and a
total height of about 14mm. The prominence of the penult, which quite equals the body-whorl in
width, is a characteristic feature; the ornamentation is very rich. A single specimen from the
“ junction-bed,’ Thorncombe, Dorset.
In Wilsonia the aperture possesses two distinct teeth: in Chilodontoidea there are three
callosities or teeth, and the internal portion of the aperture thus assumes a somewhat keyhole-
like shape: in Chilodonta the aperture is restricted by five irregular teeth, and thus becomes still
more fanciful in outline. We can scarcely doubt that these three genera (or sections) stand. in
ancestral relationship to each other, either linear or collateral.
2 Couthouya, A. Adams, 1860, sub-genus of Fossarus, Philippi, 1841, member of the Littorinide.
Cf. also Fossariopsis, Laube, from the Trias.

TABLE I,
ALPHABETICAL INDEX OF THE INFERIOR OOLITE GASTEROPODA,
WITH A TABLE OF DISTRIBUTION ACCORDING TO DISTRICTS.
NOTE.
1.—As a rule no species are quoted in this Index unless based on specimens which have been
seen by myself: Werinsa consobrina, Witchell, is perhaps the only exception. Forms provisionally
named in the Monograph are not listed: exception, Nerina sub-brevivoluta.
2.—Practically there are five districts: viz. (1) The Yorkshire Basin, Zower Division, including
the Dogger and Millepore Bed ; Upper Division, the Scarborough Limestone. (2) The East Midland
District is not at present divided into a Lower and Upper Division; it embraces the Northampton
Sand and Lincolnshire Limestone. (3) The Cotteswold District includes the Inferior Oolite outerop
from the neighbourhood of Banbury (Hook Norton) to the Mendip axis. The Zower Division comprises
the Opalinus- and Murchisonx-zones, including the Pea-grit, Oolite-marl, and the Freestones. It is
probable also that the Gryphite-grit and Lower Trigonia-grit should come in here. The Upper
Division includes the Upper Trigonia-grit and Clypeus-grit with their equivalents, lying for the most
part in the Parkinsoni-zone. (4) The Dundry exposure is regarded as a district by itself, not at
present divided. (5) The Dorset-Somerset District extends from the Mendip axis to the Channel at
Burton Bradstock. The Zower Division includes the Yeovil Sands, together with the Opalinus-zone,
Murchisonz-zone, and Ooncavus-bed (in the early part of this Monograph called the Sowerbyi-bed).
The Upper Division includes the Sauzei-bed, which is much more nearly on the Sowerbyi-horizon, the
Humphriesianus-zone generally, and the Parkinsoni-zone.
3.—In the columns a “ note of interrogation”’ (?) in some cases signifies that the identification is
questioned, in others that the locality is in doubt. In those cases where an Upper and a Lower
Division are adopted, the query may relate to the Division only. With respect to the East Midland
District there is considerable difference between the Fauna of the Lower Division of the Lincolnshire
Limestone, as exemplified by the extremely fossiliferous horizon at Lincoln, and the Fauna of the
Upper Division, as exemplified by the beds at Weldon and Pontcn; but since some fossiliferous
localities are doubtful it has been thought best not to attempt to distinguish an Upper and Lower
Division.

1 It is probable that more species of Pleurotomaria occur in the Cotteswold District than those quoted in the

often uncertain. Thus we may expect to find Pl, elongata and other common species.

Of the above species, some, such as Cerithium Roissyi and other Bathonian forms, most probably
occur in the higher beds, and especially in the Paludina-bed at Langton Bridge, which has more of a
Great Oolite than an Inferior Oolite fauna, The same may also be said of Watica Stricklandi (quoted
by Witchell from the Clypeus-grit), and possibly other Bathonian species of Natica. Again, we may
regard Nerita pulla as a general term for any small Nerita (Neridomus), which in the Inferior Oolite
may possibly be covered by Nerita tumidula. Delphinula alta, as it occurs in the Lincolnshire Lime-
stone, has been split up into two species, each of which differs more or less from the Great Oolite
form.
On the other hand, it seems highly probable that some of the names on the list, such as Naticu
macrostoma, Turbo princeps, and several more, are the result of incorrect identification.

POSTSCEHIPT.
In addition to the species described and figured in the foregoing Monograph,
there are several others in my own collection which I have not ventured to bring
forward, in most cases because of their imperfect condition. This is notably the
case with regard to some specimens obtained in 1887 from the Yeovil sands on
the coast, most probably from the Dumortieria-beds and other horizons of the
Jurensis-zone.
PLATE XLULL.
N.B.—A few figures of Trochotoma in this Plate ave drawn from photographs. All
specimens are from my Collection unless otherwise stated, and the same applies
to the remainder of the Plates.

I am greatly indebted to many fellow-workers in this field of Paleontology, to
whom I wish to render my sincere thanks. Especially to Professors Dewalque,
J. Fraipont, and M. Lohest of Liége, Prof. Geinitz of Dresden, Dr. Otto Jaekel of
Berlin, and to Mons. L. Dollo of Brussels, who kindly assisted me to study the
series of Coal-measure fossils in the respective Museums to which they are
attached.
Talso have to thank Dr. H. Woodward, Professor McKenny Hughes, Mr. J. W.
Carr of Nottingham, Dr. John Young of the Hunterian Museum, Glasgow,
Messrs. Crowther of Leeds, Howse of Newcastle-on-Tyne, Platnauer of York,
W. Carr of Cardiff, H. Woods of the Woodwardian Museum, Hoyle of Owens
College, and Crowther of Derby, for kind permission to study all the material
in the various museums under their care, and for the loan of specimens for the
purposes of figuring.
Also to Messrs. J. W. Kirkby of Leven, Dr. J. R. 8. Hunter of Braidwood,
J. Neilson and J. Beveridge of Glasgow, J. Smith of Kilwinning, R. Kidston of
Stirling, James Bennie of the Scotch Geol. Survey, R. Craig of Beith, Joseph
Wright of Belfast, Wm. Madeley of Dudley, George Wild of Bardsley, C. Roeder
of Manchester, G. Campbell of Wakefield, Wm. Pickup of Rushton Colliery,
Johnson of Dudley, and John Ward of Longton for the loan of large collections,
and for many details as to distribution.
Also to Sir A. Geikie, Director-General, and Messrs. E. T. Newton, De Rance,
Goodchild, and Nolan, of the Geological Survey of Great Britain and Ireland, for
great assistance in the loan of type specimens from the Survey Museums of
London, Edinburgh, and Dublin, and for valuable information on many points.
Also I have to thank Mr. F. R. C. Reed, of Cambridge, for kindly showing me the
Woodwardian Collections on two occasions, and Mr. Bolton, of Owens College,
Manchester, for his kindness in giving up to me a work which he had already
begun, and for looking over proofs for me; and Mr. William Rupert Jones, who
kindly verified references and made several bibliographical researches for me.
I owe a special debt of gratitude to the Rev. Prof. Thomas Wiltshire and
Prof. T. Rupert Jones for many valuable suggestions and much help.

Bibliography.
1853. In a paper ‘‘ On the Coal-measures of the South Jogeins, Nova Scotia,”
Sir W. J. Dawson at p. 39 figures two shells as Modiole (figs. 22 and 23), and
two as Uniones (figs. 24 and 25), from these measures. No specific names.
1862. Winchell described, in the volume of the ‘ Proceedings of the Academy
of Natural Science of Philadelphia’ for 1862, p. 413, Cardinia complanata, C.
equimarginalis, said to be closely allied to C. robusta, and C. concentrica, from
Carboniferous beds of the Marshall and Huron groups of Michigan. |
1864-5. Messrs. Meek and Worthen (‘‘ Paleontology of the Upper Missouri,”
part i, p. 34, ‘Smithsonian Contributions to Knowledge,’ No. 172) include
Carbonicola (spelt Carbonocola) in the family Crassitellide, with Astarte,
Crassatella, Cardita, &c., and a very large number of fossil genera of most
diverse characters,—Venericardia, Pachydomus, Astartila, Astartella, Cardinia,
Hippopodium, Pleurophorus, and various others.
At p. 36. Anthracomya is included in the family Anatinide, with Anatina,
Thracia, Pandora, and Pholadomya, and other recent genera, and with the fossil
genera Carcomya, Allorisma, Myciates, Arcomya, Cardiomorpha, Sedegwickia,
Sanguinolites, and others. Such a group,. with scarcely a character in common,
cannot be admitted for a moment.
1875. Baily gives a figure of Carbonicola ovalis under the name Anthracosia
centralis in his ‘ Figures of Characteristic British Fossils,’ p. 115, pl. xxxix, fig. 8,
from the Coal-measures of Wednesbury, South Staffordshire.
1878. Bigsby’s ‘ Thesaurus Devonico-Carboniferus’ gives lists of all the
then known species of Devonian and Carboniferous Lamellibranch fossils. The
following are from American Carboniferous strata (p. 296) :
Anthracosia equimarginalis,: Winchell. Anthracosia concentrica,? Winchell.
— Antigonesensis, Dawson. — Sragilis (?), Cox.
— Bradorica, Dawson. - nana, Owen.
1 This shell is referred to Edmondia by S, A. Miller.
2 This shell is referred to Sanguinolites by S. A. Miller.
174 CARBONICOLA, ANTHRACOMYA, AND NAIADITES.
Anthracosia occidentalis, Swallow. Anthracoptera fragilis, Meek and Worthen.
a subangulata, Dawson. — levis, Dawson.
Anthracoptera carbonaria, Dawson.
1889. S. A. Miller, in his work on ‘ North American Geology and Paleon-
tology,’ gives at p. 462 a brief definition of the genus Anthracomya, referring
several of Dawson’s Acadian species of Naiadites to this genus, amongst them
Naiadites carbonaria. On p. 463 he gives short definitions of Anthracoptera
and Anthracosia, referring A. polita, White, to the former, and A. Bradorica to
the latter genus.
1894. A paper entitled ‘* Revision of the Bivalve Mollusks of the Coal-forma-
tion of Nova Scotia,” by Sir W. J. Dawson, was issued by the Peter-Redpath
Museum. He reviews the whole question of the nomenclature of Anthracomya
and Naiadites, and figures the following new species:—Naiadites longus, N.
mytiloides, and Anthracomya obtenta. The older species are re-figured, and
remarked upon at length.
1896. Holroyd and Barnes, in vol. xxiv, pt. 5, ‘ Transactions Manchester
Geol. Soc.,’ ‘On the Rocks and Fossils of the Yoredale Series of the Marsden
and Saddleworth Valleys,’ note the occurrence of several species of Carbonicola
in that series, amongst which I note C_ turgida, OC. acuta (small), and C. aquilina.
Additional Notes on the Species.
Carbonicola robusta (p. 45).—On p. 48 I remarked that the only specimens
of this species that I had seen with eroded umbones were from Codnor Park,
Derbyshire. I have since then acquired several specimens from Shotts, which
show this condition remarkably well, one of which I figure, Pl. XXI, figs. 11
and 12. The name Unio discrepans, Brown, 1849, ‘ Fossil Conchology,’ p. 218,
pl. Ixxxviii, fig. 24, should be added to the synonymy of C. robusta.
C. ovalis (p. 56).—To the synonymy of this species should be added
Anthracosia centralis, Baily, 1875, ‘Figures of Characteristic British Fossils,’
pe tloppl. xxx, fig. s.
C. obtusa (p. 61).—This shell has been found in cee abundance in a
bed of black shale a few yards above the Moss Coal in sinking a new pit at
Longton, North Staffordshire Coal-field. It occurs with C. gibbosa, C. aquilina,
C. acuta, and C. turgida.
C. nucularis (p. 63).—This species occurs in large quantities in the ‘‘ cockle-
shell”? bands above the Rushey Park seam, St. Helens. The shells from this
locality are much larger than those found in North Staffordshire, and exhibit
APPENDIX. 175
much variation in form. One is figured Pl. XXI, fig. 8. It has also been found
in the roof of the Bute seam, Dyllas Colliery, South Wales.
CO. aquilina.—To the synonymy of this species must be added Unio littoralis,
Brown, 1849, ‘ Fossil Conchology,’ pl. lxxxviu, fig. 7.
The Ure Collection is, I find, preserved in the Museum of the Royal Society
of Edinburgh, and the Council have kindly lent me the shell which is supposed to
be Ure’s “ mussel,” and which should therefore be the type of Fleming’s Unio
Ure. This shell, which is figured on Pl. XXI, fig. 1, is not very easy to identify,
but I believe it to be a young specimen of Carbonicola acuta. Sowerby’s shell
is published in vol. 1 of the ‘Mineral Conchology,’ which is dated 1813;
Fleming’s ‘ History of British Animals’ is dated 1826; therefore Unio Urei must
be placed as a synonym of Carbonicola acuta, and not, as I have suggested p. 69,
of C. aquilina. I would point out that the shell now figured differs much in
size from Ure’s original drawing, the latter being the representative of a much
more massive and older shell.
To the localities where Carbonicola aquilina is obtained should be added the
roof of the 4-foot seam, Bwllfa Colliery, and the roof of the 2-foot 9-inch seam,
Galli, and a bed of Ironstone, Aberdare, all in the South Wales Coal-field. Also
the Yoredale series of Marsden, Pule Hill.
Carbonicola similis (p. 76).—Some fine specimens of this shell have been
obtained from some Ironstone measures at Aberdare, by Mr. O’Connor.
Carbonicola turgida.—To the localities for this species (p. 67) should be added
the Ironstone seam of Aberdare, and Pule Hill in the Yoredale series.
Anthracomya Adamsii (p. 89).—This shell has been obtained in a bed of iron-
stone at Aberdeen by Mr. O’Connor, and in a bed of black shale with Ironstone band
and Cyprid beds a little way below the Burdiehouse limestone on the shore at
Dalmeny by Mr. James Bennie. The specimens are all crushed flat, but have the
periostracum well preserved.
Anthracomya modiolaris (p. 95).—This species has been obtained by Mr.
O’Connor from the roof of the 4-foot coal, Bwllfa Colliery, South Wales.
Anthracomya senex (p. 111).—A very perfect example of this species has been
obtained by Mr. O’Connor from a bed of Ironstone at Aberdare; 1 have also
obtained this species from the Lancashire Coal-field.
Anthracomya Wardi (p. 105).—Mr. O’Connor has obtained this species from
the roof of the Hllad seam, Brysbach, South Wales Coal-field.
Two very fine shells obtained from the Possil Lower Black-band, in the collection
of Dr. John Young, resemble very closely certain smaller shells which I figured
on Pl. XIII, figs. 18, 15, and 16. All the other adult forms, and most of the
young ones of this species which have come to hand, are compressed, and otherwise
distorted (Pl. XV, figs. 12—16, 18, and 20). The position of the umbones and
176 CARBONICOLA, ANTHRACOMYA, AND NATADITES.
the characteristic form of the anterior end and the subparallel margins appear to
me to be typical of A. Wardi.
Dr. Young tells me that these are the only shells of this species known from
this locality, and that he has not met with this form before. I have no hesitation
in referring them to the genus Anthracomya, and to the same species as figs. 13
and 15 of Pl. XIII, although the Possil shells are so much finer than any others.
Conditions must have been extremely suitable for the growth and development of
the shell in this locality, and it is remarkable that no more specimens are to be
met with in Scottish collections. Dr. Young informs me that crushed forms of
Naiadites, probably N. modiolaris, occur with this shell, and that Lingula squami-
formis also is found in bands of black shale in connection with the Possil Lower Iron-
stone, but that Naiadites and Lingula never occur in exactly the same stratum.
Of Dr. Young’s two-specimens one is very much larger than the other. The
finer example (Pl. XXI, fig. 9) is, however, somewhat crushed and imperfect at
the anterior end, and does not show the typical form of the shell so well as the
other (Pl. XXI, fig. 10).

Anthracomya Phillipsii (p. 120).—Pl. XXI, fig. 7, is a non-compressed
example of this species from the Upper Coal-measure shales, Speedwell Pit of the
Gloucestershire Coal-field. Typical compressed examples occur in the same
shales. |
Anthracomya dolobrata has also been obtained from the Lancashire Coal-field ;
two specimens, of which I figure one, fig. 13, are assuredly young.

Specific Characters.—Shell moderately convex, especially in front, transversely
oblong. Superior and inferior borders subparallel. The anterior end is short,
convexly swollen, and has an almost semicircular margin, passing gradually
below into the inferior border, which is straight, or with an almost obsolete
sinuation a little anterior to its centre. The posterior border is truncate, almost
straight above, rounded below. The hinge-line is straight and long. The
umbones are tumid, obtuse, elevated above the hinge-line, and continuous, slightly
excavated in front by a well-marked but small lunule; and are situated very
anteriorly in the anterior one-sixth of the shell. The valves are convexly
swollen; there is a shallow contraction which passes obliquely downward and
backward from the back to the lower margin, becoming wider as it nears the
lower edge of the valve, which indistinctly marks off the anterior from the
posterior part of the shell. Posterior to this sulcus the shell is diagonally swollen
from the umbo to the posterior inferior angle, the swelling becoming less marked as
it proceeds backwards. Above the swelling the valves are flattened and
compressed into the hinge-line and posterior border.
Interior.—Casts show the usual arrangement of the adductor and accessory
muscle-scars.
The hinge is edentulous, and consists of a thickened mass in front, strongly
connected with the shell, situated immediately below the umbo, which pro-
jects downwards, and is slightly bevelled at the expense of the upper portion,
and of a smooth elongated part posteriorly bevelled at the expense of the lower
margin.
Heterior.—The surface is ornamented with many very fine, thread-like striz
and lines of growth parallel to the border of the valves. Shell thin.
Dimensions.—The type-specimen, Pl. XXI, fig. 2, measures—
Antero-posteriorly Ee 02 ; . 25 mm.
Dorso-ventrally : : NDOT
Elevation of valve . 4

Distribution.—In Carboniferous shales at Ballynascreen, and Slieve Gullion, co.
Derry; Clogher, co. Tyrone, and Ballycastle, co. Antrim. Lower Carboniferous
shales of co. Cork and co. Tipperary (Baily).
Observations.—This shell is very distinct from those named Modiola Macadamiit
by Portlock, although he was not altogether of this opinion, for he says, ** Though
this appears so very distinct a form from Modiola Macadamii, I am disposed to
think that they all merge one into the other.’ As a matter of fact two of the
varieties of M. Macadam are very distinct indeed, and all are totally different

from the shell under description. The shale in which A. subparallela occurs is
lithologically distinct from that in which the other forms are found.
I had figured two specimens, Pl. XVII, figs. 1 and 2, from the cabinet of
Mr. Joseph Wright, of Belfast, and remarked at p. 88, ante, that my attention
had been drawn to the resemblance between this shell and those of the genus
Anthracomya; and since that time I have been able to study the original specimen
on which the species was founded, now preserved in the Museum of the Geological
Survey, Jermyn Street, and some more specimens from Ballycastle in the Belfast
Museum, two of which have the hinge exposed. This material came into my
hands after the letterpress of my observations on Anthracomya was printed off,
but I mentioned the fact that I had come to the conclusion that the shell really
belonged to that genus in a note on the page of explanation to Pl. XVII.
I now re-figure the original type by the kind permission of Sir A. Geikie, and
a specimen showing the greater part of the hinge by the permission of the
authorities of the Belfast Museum. ‘The hinge, it will be noted, differs from that
of A. modiolaris in not possessing an elongated posterior lateral tooth, so that this
character cannot be considered typical of the genus. I have not met with A. sub-
parallela in the beds at Hollywood, near Belfast, where Modiola Macadamii occurs.
This species resembles more nearly A. punctata than any of the others, but is
more convex, the lateral constriction is better marked, and the lines of growth
are somewhat oblique to the long axis of the shell.
There is a fine slab of this species in the Geological Survey Collection at Dublin
from Sheve Gullion, Derry, showing a large variety of shells in various stages of
growth. In the younger shells the oblique sulcus is more marked.
Baily (‘Figs. Char. Brit. Foss.,’ 1875) evidently considered all the forms
described by Portlock as one, for he figures M. subparallela, and in the text
(p. 114) unites it with Macadam of Portlock and its varieties.
Keyserling and Hichwald both referred specimens from Russian Carboniferous
beds to Portlock’s species, but altered the generic name to Cardinia.
A figure is given by Keyserling (op. sup. cit.), and this differs somewhat in
contour from Portlock’s type. Hichwald’s description is short, and would do
for A. subparallela.
Naiadites modiolaris (p. 131).—To the localities for this shell should be added
the roof of the 2-foot 9 seam, Galli Colliery, and the roof of the 4-foot seam,
Bwllfa Colliery, South Wales.
N. carinata also occurs in the latter bed.

OF THE
BRITISH CARBONIFEROUS LAMELLIBRANCHIATA.
INTRODUCTION.
No systematic work on British Carboniferous Lamellibranchiata has been
attempted since the publication of M‘Coy’s two great works in 1844 and 1854-6.
Since then systematic conchology has greatly advanced, and, at the same time,
paleontological material has been accumulated to a very large extent ; fortunately,
too, In many cases specimens or fragments have been obtained in special states of
preservation, which have demonstrated the characters of the hinge-structure and
the position of muscle-scars, and the character of the pallial line—features which,
in the necessary absence of the soft parts of the animal, are made use of as a
basis of conchological classification. Owing to the fact of the preservation of
these essential characters, many changes have been found necessary in the generic
nomenclature ; and will be adopted in the following Monograph.
The study of the bivalve shells of the Carboniferous age has been largely carried
on, both in Belgium and North America, by learned and competent observers,
consequently much uncertainty has been caused by such independent and widely
separated research, authors being unwilling, in the absence of specimens, to admit
that the same species had a world-wide distribution ; and the result has been that,
both generically and specifically, a large synonymy has been created.
In nearly every case the older paleontologists named their specimens from the
observation of external characters only, and often from a supply of specimens
too limited to ascertain the real type of a genus or species; and it has generally
been the rule to regard the survival of genera and species as altogether limited to
those periods adopted for the purposes of stratigraphical classification, and to
hesitate to recognise the same form in the beds of two or more different epochs.
The all but universal acceptance, by working conchologists, of the Darwinian
theory of evolution by variation has to a large extent changed the views which
older observers held on the permanence of species. It may be now regarded as an
1

aphorism that the larger the number of specimens examined the fewer the species
determined, or that the number of species varies inversely with the number of:
specimens studied. ,
The question of species, and to some extent that of genera, is largely a personal
one. Hach individual observer gives a different value to variations in shape, size,
or even to small anatomical differences ; and when, asin paleontological research,
it is impossible to obtain any but the most elementary evidence of the anatomy of
the animal itself, and one organ—the test—has to furnish the characters for classi-
fication, the most reliable portions, the hinge and interior, often being invisible
together with the imperfections of the geological record), an approximation only
can be made to accuracy in zoological determinations.
The work of American authors is scattered through numerous publications
access to which is often difficult. In many cases no figures accompany the
descriptions, and the type specimens are not recorded, and are scattered over
that Continent in private collections. Very few British species are recognised as
occurring in American Carboniferous rocks, though there is avery close resem-
blance between the two faunas, and but small differences seem to exist in many
cases between British and American species—an extent of variation not greater
than would be expected to exist in a single species surviving in such widely
separated areas. ‘The greater accuracy in generic delineation is greatly due to the
recognition by American authors of the importance of the internal characters of
the shell, and to the fine state of preservation in which in many cases specimens
occur in American beds. Many of their generic names have been accepted by
de Koninck and others, in order to mark off recent from paleeozoic fossil genera.
Fortunately in many cases the original types of the published British Carbo-
niferous Lamellibranchs are still extant. The ‘Ure Collection” is preserved in
the Museum of the Royal Society of Edinburgh.
The few forms described and figured by Sowerby in the ‘ Mineral Conchology ’
are, the writer believes, all present in the Sowerby Collection of the Natural History
Museum at South Kensington, and in the same place are those specimens which
were described by Phillips in the ‘ Geology of Yorkshire,’ from the Gilbertson
Collection, while Portlock’s specimens are all safe in the Museum of the Geological
Survey at Jermyn Street. The Griffiths Collection, the basis of M‘Coy’s first
great work, is preserved in the Science and Art Museum, Dublin; but many of the
specimens figured, probably those from private collections, have been lost sight
of. The specimens figured in M‘Coy’s second great work are all in the Wood-
wardian Museum at Cambridge, while those described by the paleontologists of
the Geological Survey are in the museums of that Department in London, Edin-
burgh, and Dublin. By the courtesy of the custodians I "am permitted to
refigure in every case the original specimens.
INTRODUCTION. 3
Occasionally the original type is absent from some of these collections, and at
times its place is taken by one or more specimens from the same locality whence
the original specimen was obtained. <A certain number have, unfortunately,
altogether disappeared; and it will be necessary, owing to absence of any
accurate and detailed diagnosis, to drop certain names of long standing, since it is
impossible now to obtain the slightest indication of what the original shell was
like. An example of such a case is the Modiola granulosa of Phillips, the original
of which is stated to have been drawn from a specimen in the Museum of the
Yorkshire Philosophical Society. But there is no specimen there that in any way
can be referred to the drawing, and the whole of the description is contained in
ce
the five words ‘‘ very elongated, depressed, surface granulose,’’ which convey no
meaning of any diagnostic value.
There is a very great initial difficulty in determining the proper place in
general classification which the Palwozoic genera of the Lamellibranchiata should
occupy. In many cases no recent representatives: seem to exist; and, even with
full details as to hinge-structure, it is a matter of great uncertainty as to which
family a genus should be referred. Several of the Carboniferous genera seem to
fall into natural groups; for example, Cardiomorpha, de Koninck; Jsoculia,
M‘Coy; Broekia, de Koninck ; Pachydomus, Morris ; Hdmondia, de Koninck; and
Scaldia, de Ryckholt, have much in common, but can be distinguished by well-
marked characters ; but the real position of this family is so uncertain that de
Koninck, in spite of the absence of a sinuated pallial line in all members of the
group, places the six genera under the Anatinide ; while M‘Coy refers Hdmondia
to the Mytilidex, and Cardiomorpha to a new family placed directly after the
Mytilide. More light will be thrown on these still obscure points only when a
careful comparison can be made between the Paleozoic and Mesozoic shells, to
permit of which it will be necessary to obtain the hinge-plate of each genus.
It is impossible, in the present state of our knowledge, to attempt to arrange
the various genera under their proper families ; but the writer hopes to be able to
do so at the end of his work, when the tangled web of synonymy shall have been
unravelled, and some definite information has been obtained of the genera of
the Lameéllibranchiata which existed in Carboniferous times. Owing to the
want of material and other causes, the chief of which is the very excessive
number of species that have been figured and described by various authors, it has
been necessary to leave the study of the Carboniferous representatives of the
families Pectinide and Aviculide for a future time. This work, therefore,
commences with genera of the family Mytilide, which existed in Carboniferous
times. An attempt will be made to proceed systematically from this point,
though, owing to the present uncertainty as to the true family position of certain
genera, some rearrangement may be found to be necessitated in the final résumé.
4, CARBONIFEROUS LAMELLIBRANCHIATA.
The species of certain families of Carboniferous Lamellibranchs—Carbunicola
(Anthracosia), Anthracomya, and Naiadites (Anthracoptera)—having been fully
described in a former Monograph, will be only briefly alluded to in the present
work; but it is deemed inadvisable to omit them altogether, as these genera form
intermediate links between other Paleozoic groups.
The greatest systematic work on the subject of this Monograph is that by
L. de Koninck, a brief synopsis of which will be found hereafter. I have had the
opportunity of personal examination of all the specimens in the collection of types
in the Musée de I’Histoire Naturelle at Brussels, which formed the material for
that work, owing to the kindness of Professor Dupont. These specimens are all
from the “ Calcaire Carbonifére ”’
from that which obtains in British rocks of Carboniferous age, only about 8 per
cent. of all the species described being recognised as occurring in British rocks.
This difference is, I think, largely due to differences in the deposits in the
two areas. In Great Britain the larger number of our Carboniferous bivalves
are obtained from the shales and argillaceous deposits which were probably laid
down contemporaneously with the great ‘‘ Massif” of limestone in Belgium, and
with the smaller masses in Derbyshire, Somersetshire, Wales, and Ireland. But
of Belgium, and as a fauna differ very markedly
these English deposits, judging from many collections, do not appear to contain a
fauna by any means rich in Lamellibranchs. In Ireland, however, conditions were
somewhat more favorable to the growth of bivalves, for M‘Coy described 195
species from the Carboniferous Limestone; a number which is probably far in
excess of the truth, as many species were founded on mere variations of shape and
size ; andit is probable that in the case of the Pectinide, of which genus sixty-nine
species were described, the varied ornament and sculpture of the right and left
valves served to separate the two halves of a shell into two species.
Mr. G. H. Morton,’ in a careful and exhaustive work on the Carboniferous
Limestone of North Wales and its fauna, only mentions twenty-four species of
Lamellibranchs as occurring within the district in which he laboured, and these
only very sparingly.
The Brachiopoda are by far the most common fossils in the Carboniferous
limestones of England and Wales, both as regards numbers and wideness of
distribution. ‘They are by no means evenly distributed throughout the mass, or
even in the same bed; certain portions of limestone are almost wholly made up of
fossil shells, others are almost free from them; but the fossiliferous pockets are
comparatively rare, and the shells are almost all broken and the valves separated,
affording evidence that the shells are not exactly in the place where they lived.
This is not the case where the shells are obtained from the shales intercalated
between the thin beds of limestone in the Northumbrian Scottish area.

INTRODUCTION. 5
Various attempts at classification have been made in the case of Carboni-
ferous strata, but with no very satisfactory result. For while it is easy to
classify the rocks which represent, in any area, the Carboniferous beds, it
is with great difficulty that any decision can be arrived at as to the exact
equivalents of the beds in two series of rocks of different areas. It appears
to the, from lithological and palzontological points of view, that the rocks which
represent the Carboniferous period in Northumberland and Scotland were laid
down on a slowly sinking floor in very shallow water, at times probably fresh or
very slightly brackish, while occasionally depression went on more rapidly and
deeper marine conditions obtained. In the Derbyshire area, at first, a steady
marine deposition was going on at some considerable depth; but as time went
on the land sank less rapidly, the sea basin became almost filled, the shallow
water or shore beds extended further south, and the continuous formation of
calcareous ooze was replaced by the deposition of the muds and sands brought
down by river and other agents of surface denudation, not permanently at first,
owing to oscillations in the rate of the lowering of the land. Little can be known
of the comparative rates of the deposit of the alternating beds of the Calciferous
Sandstone group and the Mountain Limestone, because, on the one hand, the
succession and repetition of strata point to varied rates of deposit, and the
rich fossil flora and seams of coal entombed in the rocks indicate intervals in
the deposit, and it 1s impossible to gauge the length of time during which the
terrestrial conditions obtained. From a paleontological point: of view, deposits of
varied depth would naturally contain faunas of different aspect, and therefore
fossils can hardly be relied upon to indicate stratigraphical Hquivalents, though they
may, in any area, mark out zones or horizons; for as the depth or clearness of the
water and condition of the bottom altered, new forms would migrate; and thus in one
Jocality certain forms would be found in horizontal sequence to others (and conse-
quently, from the point of view of time not contemporaneous), which had been living
contemporaneously in different areas : and thus in the Anglo-Scottish Carboniferous
area, as the sea deepened, southern forms would extend northward, and be
intercalated between beds containing shallower fauna; while as the basin filled up
the shallow water fauna would migrate south, and overlie that which was
characteristic of deeper water. In the Calciferous Sandstone series of the
Fifeshire coast it would appear that alternating conditions were repeated; such
lithological repetitions being accompanied by the fresh invasion of a fauna which
had been driven away from the area by an unsuitable environment, but which had
evidently survived in some other area, and was able, when suitable conditions
reappeared, to migrate back again, but at a higher level, to its old haunts.
Certain species, it is true, appear to have been able to survive under very varied
conditions; but a close examination will show a great variation in size—for
6 CARBONIFEROUS LAMELLIBRANCHIATA.
example, in shale beds Productus semireticulatus does not attain to the size which
is characteristic of this species in the Mountain Limestone. Many similar
examples can be quoted amongst the group of Lamellibranchs. I have pointed
out in a previous Monograph’ how the size of Naiadites crassa varies as it
occurs in limestones or shales, and the same thing may be noted in the case of
Schizodus Salteri in the limestone at Randerston, Fifeness, and the shale at
Woodhall, near Edinburgh. It is very interesting to note the dwarfed condition
of those typically marine fossils which are contained in certain narrow bands in
the Coal Measures of Lancashire and Staffordshire. These beds contain a fauna
comparatively rich in species, most of which occur in the Lower Carboniferous
rocks, demonstrating a prolonged survival in some external area until the marine
conditions necessary for their existence recurred in these areas. The following
list of fossils recognised as occurring in the roof of the Gin Mine or Golden Twist
of North Staffordshire has altogether a Lower Carboniferous facies :
Discites subsulecatus.
Goniatites excavatus.
Axinus (Schizodus), sp.
Orthoceras, sp.
— striatus. Solemya primeva.
— multilobus. Chonetes Lagquessiana.
Cypricardia glabrata. Nucula gibbosa.
Aviculopecten, sp. — lineata.
Euomphalus tuberculatus. Leda clavata.
Pleurotomaria, sp. Macrocheilus Michotianus.
Productus semireticulatus. Loxonema, sp.
Spirifer Urei. Bellerophon Dumontii.
But most of the species are very much dwarfed, the Productus being very small
indeed.
The marine fauna of the Pennystone beds of Coalbrookdale is very interest-
ing, both in point of view of its richness in Lamellibranch forms, and the fine
size to which these attained. ‘The richest bed occurs about the middle of the
productive Coal Measures, and has altogether a Lower,Carboniferous facies, con-
taining Spirifer bistriatus, Productus scabriculus, Rhynchonella plewrodon, Discina
nitida, Conularia quadrisulcata, Pecten, two species, Nucula, Nuculana (Leda), and
several species of Schizodus and other bivalves hitherto known as Sanguinolites, with
several species of Cephalopods and Gasteropods, some of which are of large size.
This fauna, though not exactly identical, has a close resemblance to that of the
Redesdale Ironstone, which is generally considered to be about the horizon of the
Yoredale beds of Yorkshire; the specific differences are not really greater than
might be expected to have obtained in forms surviving through long periods of
time, several species being common to the two deposits.

INTRODUCTION. 7
At the base of the South Wales Coal-field, under the Farewell Rock—not the
Millstone Grit of this district, though the name Farewell Rock is used in this sense
by the Lancashire miners—is a marine band which also resembles in its fauna the
Redesdale Ironstone even more closely than the Pennystone of Coalbrookdale.
These beds are known as the “ Rosser Veins.’ About 40 per cent. of the
Brachiopoda and Mollusca are common to the two deposits.
The molluscan fauna of the marine beds in the Ganister series of the
Lancashire, Yorkshire, and North Midland Coal Measures differs markedly from
those of the marine bands of South Wales and Coalbrookdale, the characteristic
Ganister fossils, Aviculopecten papyracous and Goniatites Listeri being conspicuously
absent. The latter is stated by Salter to occur, however, in the South Wales bed
(‘ Mem. Geol. Surv.,’ ‘‘ Iron Ores of South Wales,” p. 221, pl. i, fig. 36), but does
not seem to be present at Coalbrookdale.
These interesting recurrences of a fauna characteristic of older rocks in beds
of a more recent date cannot but point to the fact that, during the time occupied
by the deposit of the intervening rocks, certain species must have survived in
some outside area, where a definite set of conditions favorable to their survival
obtained, or only altered so gradually that, as the shore rose or sank, those forms
for whose existence a certain depth of water was necessary would not feel the
change, and would be able to slowly migrate with the varying change of the level
of the floor of the sea; while others, more plastic, became modified into new
species by accumulated variations in successive generations.
Such an alternation and repetition of conditions, bringing back with them
faunas which had once lived, died, and been emtombed at the same place, but on a
lower level, renders the value of palzeontological zones of small moment in the
matter of the correlation of the various beds of the same period in different
districts ; but, on the other hand, reasoning from the bathymetrical distribution
of the recent representatives of paleozoic forms, strong evidence of the method
and conditions under which the fossiliferous beds were deposited may be deduced.
The Carboniferous rocks of Great Britain can have been at no time laid down at
any great distance from land. The older rocks of Devon and Cornwall on the
south, Middle and North Wales, and the Lake District, and the high lands of
Galloway on the west, and due north the Highlands of Scotland, were dry land
during the Carboniferous epoch. That these points of high land could not have
been isolated islands in the Carboniferous sea is evident from the littoral deposits
- of slates and sandstones of Devonshire in the south, and the Scoto-Northumbrian
area in the north, so well developed along the line of the receding or advancing
shores, which must have been the result of surface denudation from large
land-areas, and this condition of things would necessitate a large and complicated
system of river-drainage. While in the main the general movement during
8 CARBONIFEROUS LAMELLIBRANCHIATA.
this time was one of slow depression, this was not by any means constant ;
periods of intermission, or even of elevation, marked by the growth of the vege-
tation which formed the coal, must have supervened, and at times even the gradual
movements of depression must have been accentuated, causing a retrocession of
the shore-line, and the extension of the area of marine deposit, so that the
deposition of calcareous ooze was unaffected by the mixture of sediments arising
from the denudation of the land. The pureness of the limestone deposit may
have been due either to the greater distance from such areas of contamination, or to
the existence of Barrier reefs or other submarine ridges which would filter off the
suspended matter. Deposition, however, seems to have been always in the end
greater than the amount of depression; for even in the most typical areas of
marine sediments evidence shows that there was a gradual filling up, the lime-
stones are gradually replaced by shales, with thin-bedded limestones, then shales
and sandstones, and finally the terrestrial conditions necessary for the growth of a
large and varied flora obtained.
It is not improbable that the Cambrian and Granitic areas of Wexford, Carlow,
and Wicklow were continuous with the similar deposits of Wales, and formed a
peninsula, washed on the south, north, and west by the Carboniferous sea, on the
bottom of which the thick deposits of Irish limestone were accumulating. The
Carboniferous succession of Howth, Malahide, and that neighbourhood affords
undoubted evidence of the close proximity of land, and represents the beds
deposited on the northern shore of this peninsula. Indications of a coast-line can
be traced north to Co. Down, where, on the present shore at Holywood, shales
with Modiola Macadam occur ; similar shales also being found in Londonderry
and Tyrone, from where the shore-line probably passed across to the Ayrshire
coast. The Cumbrian area of older rocks was probably continuous with those of
similar age in the Isle of Man, and perhaps the Mourne Mountains, but this mass
must have been separated from the Welsh land by a straight or deep arm of the
sea, in which were deposited the limestones of North Wales, extending as far north
as the southern part of the Isle of Man. The succession of deposit in the North
Wales area is extremely interesting, showing the following sequence, according to
Prof. A. H. Green, as quoted by H. B. Woodward, ‘ Geology of England and Wales,’
p18:
Grey limestone,
CaRBONIFEROUS Thin-bedded earthy limestone,
LIMESTONE.
Flaggy and sandy limestone ;
Mittstone Grit ( Hard, close-grained sandstones,
AND Shales,
YorEDALES .- | Soft fine-grained sandstones,
which is typical of sea gradually becoming shallower.
INTRODUCTION. 9
In a south-easterly direction the Carboniferous sea extended across the whole
east and south of England, passing over the Ardennes and North Central Europe
to the Urals. .
Judging from the presence of similar faunas wherever Carboniferous rocks are
explored, it would appear that conditions of climate were fairly equable over the
whole of the earth in those times. Indeed, it is questionable whether the
differences in the various species described from European, American, and
Australian Carboniferous rocks really indicate variations of specific value, and are
any greater than might be expected in a single species of very wide distribution.
There is a certain amount of doubt as to the true base of the Carboniferous
rocks in the South west of England and Ireland. This question was discussed by
Beete Jukes in the ‘Memoir of the Geological Survey of Ireland, Explanation
of Sheets 187, 195, and 196,’ pp. 33—37, whosummed up in favour of the Bagey
Point, Braunton, Marwood, and Pilton beds of Devonshire, and the Coomhola
Grits and Carboniferous Slate of co. Cork, being regarded as belonging to the
Carboniferous system, rather than to the Old Red Sandstone, on paleontological
grounds.
He says, p. 34, “‘ With the exception of the shells called Cucullea and’ Curto-
notus, and a few other fossils which are found almost solely in the grit stones (and
which we may suppose, therefore, to have been sand-loving animals), and a few
species such as Modiola Macadami and Avicula Damnonensis, which are found
chiefly in shales or slates (and appear, therefore, to have been inhabitants of muddy
bottoms), most of the species found in the Carboniferous Slate are also found in
the Carboniferous Limestone. It is true that the limestone has many species which
are not found in the grits, or in the shales or slates, but it is obvious that we may
attribute this also to the nature of the different sea bottoms.” The following
Carboniferous fossils occur in the debatable beds:
Fenestella antiqua. Spirifera cuspidata,
Athyris ambigua. — striata.
Productus scabriculus. Streptorhynchus crenistria.
Rhynchonella pleurodon. Terebratula hastata.
Of these he says, they ‘‘ range throughout the Carboniferous Slate as they do
throughout the Carboniferous Limestone, occurring in the grits and slates side by
side with the fossils that are peculiar to those beds.” Not only, indeed, do fossils
which are commonly found in the Carboniferous Limestone occur in the Pilton
beds of Devonshire, classed as Upper Devonian, but even in the Lynton Slates,
Lower Devonian, Fenestella antiqua and Chonetes Hardrensis, and in the Ilfracombe
beds, Middle Devonian, Fenestella antiqua, Rhynchonella pugnus, R. plewrodon, and
Streptorhynchus crenistria occur, together with a number of forms not known in
2
10 CARBONIFEROUS LAMELLIBRANCHIATA.
Carboniferous beds. Messrs. Hall, Usher, and H. B. Woodward still retain the
term Upper Devonian for the Marwood and Pilton beds. The mere occurrence of
a few forms common to other formations does not amount to undoubted evidence
for the classification of the two beds under the same system. All that can be
affirmed is that there was a gradual sequence between the two formations,
deposition going on without any break or unconformity, and that the changes in
environment were such that certain forms of life were unaffected by the alteration
of conditions. The direct connection of the Devonian and Carboniferous epochs
by passage beds is not only evident in Devonshire ; passage beds are also found
in the Forest of Dean, in Shropshire, as the Farlow beds, in the Lake District,
and in the Isle of Man, but in these cases the paleontological evidence is small
and unimportant.
From the paleontological point of view of this Monograph the upper limit of
the Carboniferous rocks is not important. The upper red beds of the Coal
Measures contain a fauna from which molluscan remains are almost entirely absent,
with the exception of Anthracomya Phillipsii and a few microscopic shells, which
have been found in the upper measures at Slade Lane, Manchester, by Mr. Roeder.
Doubtless much of the ground in Staffordshire and Warwickshire now mapped as
Permian should really, on lithological grounds and from the fossil flora contained
in the beds, be more correctly grouped as Upper Carboniferous.
It will have become apparent from the foregoing pages that it is impossible
to convey adequate information as to the British Carboniferous rocks in one
single classification.
In English text books the succession of Carboniferous rocks in the North
Midlands and Yorkshire is generally given as typical of the period. A comparison,
however, with the general succession in Scotland, Ireland, and Devonshire will at
once show the local character of this classification. The following schemes, with
the general sequence in different localities arranged side by side, will give some
idea of the very local character of much of the Carboniferous deposits; and it
appears to the writer that a twofold classification of Carboniferous rocks would be
more accurate than the threefold one that is at present generally in use. But
even then there is no accurate line of demarcation between the lower shales and
erits of the Millstone Grit series and the upper beds of the Carboniferous
Limestone and Yoredale strata. Mr. R. Kidston’ is, I see, also of this opinion,
and his views are based on the distribution of the Carboniferous flora. This
classification is as follows :

THE CARBONIFEROUS SEQUENCE IN RUSSIA.
The Carboniferous series of Russia is given in the accompanying table, which
is quoted from a paper by Mons. Tschernichew in the ‘ Annales de la Société
Géologique du Nord,’ tome xvii, 1890, p. 201.

The same author goes on to state that he considers his Stage A to represent
the Yoredale, Carboniferous Limestone and Calciferous Sandstone beds of Great
Britain, while his Stage B is equivalent to the Gannister and Millstone Grit
Series, and Stage C to the Upper and Middle Coal-measures. Certainly, from a
paleontological point of view, such a comparison of strata, differing widely in its
fauna and in lithological characters, seems absurd, and it points to the utter
hopelessness of attempting to make the Carboniferous series of widely separated
areas conform to subdivisions typical only of a single area in Great Britain. In
Russia it is evident that marine conditions persisted steadily through the greater
part of Carboniferous time, and that the rate of deposit must have been identical
with the rate of depression, consequently the lacustrine and terristial conditions
necessary for the growth of plants to form the coal only obtained at the
commencement of the period.
1 In the text Productus corrugatus, P. semireticulatus, P. longispinus, P. scabriculus, Rhyncho-
nella pleurodon, Athyris ambigua, Orthis resupinata, &c., are said to occur in stage B. These fossils
are, however, in Great Britain characteristic of the Mountain Limestone, though some of them do
pass up into the Coal-measures of Coalbrookdale and certain Yoredale beds.

BIBLIOGRAPHICAL SKETCH.
Tur Mollusca of the Carboniferous period have been carefully studied by
several authors, some of whom have published extensive works on the subject ;
four of these, Phillips and M‘Coy in Great Britain, and de Ryckholt
and de Koninck of Belgium, stand out prominently as standard authorities, and
are responsible for by far the greater number of accepted generic and specific
names. The extension of biological knowledge, and, above all, the universal
acceptance of the Darwinian doctrine of the non-permanence of species, have
rendered necessary a review of the work of even these great authorities; and
further, the large amount of material accumulated in museums and _ private
collections, has enabled the more fortunate observers of to-day, in a few cases, to
place the genera and species in a more satisfactory order on anatomical grounds,
not before apparent.
In the following sketch all reference to the Coal-measure genera Carbonicola,
Anthracomya, and Naiadites is omitted, a bibliography of these genera having
been given in a previous publication (Pal. Soe. vol. for 1894).
1793. I find that the first reference to the fossil Lamellibranchiata of the
Carboniferous period is by the Rev. David Ure, in his ‘ Natural History of
Rutherglen,’ published in 1793. He refers to two marine forms (p. 310), one of
which he calls the “‘ Cockle,”’ (pl. xv, fig. 2); two others (pl. xv, figs. 5 and 6) he
regards as two species of the “ multi-articulate Cockle,” of which he observes,
*“The hinge, which is observable in casts only, consists of about twelve teeth
on each valve.” Under this head figures of unmistakable (Leda) Nuculana and
Nucula are given. He goes on to say, ‘‘ Two species of the Muscle are found in
Kilbride, figs. 5 and 6, pl. xvi. Specimens of the former are in casts, and are very
rare. The latter are in till or ironstone “ mostly in single valves.” John Gray,
in his life of Rey. D. Ure, 1865, gives Avinus carbonarius, Portlock, as Ure’s
“cockle”’; Leda attenuata and Nucula gibbosa as the ‘‘ multi-articulate cockles ”’ ;
3
18 . CARBONIFEROUS LAMELLIBRANCHIATA.
Pteronites persulcatus, M‘Coy, and Myalina, sp. doubtful, as the two kinds of
“muscle.” !
1809. Nothing further seems to have been noted till W. Martin brought out
his ‘ Petrefacta Derbiensia’ in 1809. He refers all fossil forms to living repre-
sentatives. Only four forms of Lamellibranchs are described in the work:
Conchyliolithus Arcites cancellatus == ACH.
5 » rostratus = Conocardium.
3 Pinnites flabelliformis = Pinna.
Mya ovalis = Carbonicola ovalis.
1813-18. Very few Carboniferous Lamellibranchs were described or figured by
Sowerby in his great work, ‘The Mineral Conchology.’ The following genera and
species are described and figured :
Sanguinolaria gibbosa. | Nucula Palme.
Cardium Hibernicum. | Pecten granosus.
— elongatum. _— papyraceus.
Inoceramus vetustus. — plicatus.
Isocardia oblonga.
In 1828 Fleming (‘ Hist. Brit. Anim.’) recapitulates, with a short description
in each case, those Carboniferous species which had already been described by
previous writers, and in some cases (Mytilus crassus, Corbula limosa) by himself,
and at the same time describes most carefully Hiatella sulcata and Corbula limosa
from Carboniferous strata. No figures, however, of the new shells aregiven. The
following species are enumerated :
Sanguinolites gibbosa. Pinna flabelliformis.
Hiatella suleata. Nucula palme.
Corbula limosa. — attenuata.
Cardium aleforme. ; — gibbosa.
Isocardia oblonga. Arca cancellata.
Unio Urei. — rostrata.
Modiola bipartita? Pecten dissimilis.
Mytilus crassus. — papyraceus.
In 1829 Hoéninghaus published a list of fossils in the Museum of the University
of Bonn (‘ Verzeichniss der dem Museum der Universitiit Bonn,’ Petrefacten-
Sammlung), giving the localities whence each species was obtained, but nothing was
attempted in the way of description or illustration.
1828. In ‘ Zeitschrift fiir Mineralogie,’ vol. i, for 1828, H. G. Bronn, on p. 262,
1 Ure’s collection is now in the Museum of the Royal Society of Edinburgh.
2 The specimens of I. bipartita figured by Sowerby in the ‘Min. Conch.’ are from Parkham
Park, Surrey, and therefore not Carboniferous. Sowerby, in his remarks on that species, says that certain
shells from Llantrissant, near Cardiff, belong to the same species, but does not figure them. This
name, therefore, cannot be used for a Carboniferous shell.

gave the name Posidonia Becheri to a certain Coal-measure shell. Later on, in
1835—1837, in his ‘ Lethaea Geognostica,’ finding that the name Posidonia had been
given to a genus of plants, he considered it inadmissible for a genus of shells, and
substituted the name Posidonomya, and refigured P. Becheri, together with
Pterinea levis, Cardium elongatuwm, and Hippopodium ponderoswm, the last being
probably erroneously stated to belong to the Carboniferous strata. In the ‘ Index
Paleontologicus’ of the same author, published in 1848, lists of the known
Carboniferous Lamellibranch fossils are given.
In 1836 Professor John Phillips published his great work on the “ Mountain
Limestone District,” being Part II of ‘ Illustrations of the Geology of Yorkshire.’
In this volume are described fifty-six species belonging to eighteen genera of
Lamellibranchiata from the Carboniferous beds of Derbyshire, Yorkshire, and
Northumberland, of which forty-nine species are described and figured as new ;_ but
one of these, Pinna costata, is said to be “ probably the species figured by Martin
under the names of Pinna flabelliformis and P. nuda.”
Many of the type specimens are fortunately preserved in the ‘‘ Gilbertson
Collection” of the Natural History Museum at South Kensington, but a few are
in the Museum at York, and others have completely disappeared.' Under such
circumstances there is great difficulty in arriving at a conclusion as to which
shell is supposed to be represented by the figure, owing to the meagre descrip-
tions and the poorness of the plates; and it would appear that individual figures
are often a compound of several views from different aspects of the same shell.
This work is of the highest importance in the history of Carboniferous paleeonto-
logy ; previous to its issue only about twenty-three species belonging to fourteen
genera of marine Lamellibranchs had been recorded, and the majority of the
genera and species are still accepted.
1836. Dr. Rhind, in his ‘ Excursions Illustrative of the Geology and Natural
History of Edinburgh,’ gave a note at p. 143 of the occurrence of “ two species
of Testacea. One of these is decidedly a Mytilus; ..... the other species
resembles the Mactra subtrwncata”’ in shale at Woodhall, Water of Leith.
In 1838 the same author, in a little book entitled ‘ The Age of the Earth,’ gave
a plate with four Unios from the Coal-measures of Polmont, and Awinws Pent-
landicus and a Modioliform shell from Woodhall, Water of Leith, now recognised
as a dwarfed form of Naiadites crassa.
On February 5th, 1834, Prof. (now Sir) J. Prestwich’s paper on the ‘ Faults
which affect the Coal-field of Coalbrookdale’ was read before the Geological
Society of London, and in the ‘ Proceedings of the Geol. Soc.,’ vol. 1, p. 20, it is
1 Tt is believed that, on Prof. Phillips’s arrival in London by coach, from York on his way to
Oxford, one of his boxes of fossils was stolen at the Bell Savage Yard, and the stones, not being of
value to the thieves, were thrown over Blackfriars Bridge.
20 CARBONIFEROUS LAMELLIBRANCHIATA.
stated that “the author concludes his memoir with some observations on the
fOSSHE =. ha! of eighteen genera of shells which he enumerates, twelve are
marine.’ A memoir on the ‘Geology of Coalbrookdale,’ by Joseph Prestwich,
jun., “was commenced” on April 13th, 1836, and concluded on the 27th,
‘ Proceed. Geol. Soc.,’ vol. 1, p. 401. At p. 405 it is stated that ‘* The fossils of
the Coal-measures are described with great detail.”” The paper was not published
in the ‘ Transactions’ of the Society till 1840, when there appeured an Appendix
by Mr. J. de Carle Sowerby, describing and figuring the eighteen genera of
shells before mentioned.
Although probably determined in 1834 and 1836, these fossils can be recorded
as named only in 1840, according to the rules of nomenclature. There are twenty
species of various genera of Carboniferous Lamellibranchs described in the paper ;
though, with possibly only two exceptions, the names given to the eight genera
therein enumerated can no longer stand on biological grounds. The following
marine Lamellibranchs are described and figured :
Unio Urei. Nucula zqualis.
— Ansticei. | — accipiens.
— parallelus. — acuta.
Donax ? suleata. | Pecten gentilis.
Venus ? carbonaria. — sealaris.}
During the years 1834—1840 Goldfuss issued, in parts, his great work, ‘ Petre-
facta Germanica. Unfortunately, though he gives with care the localities whence
his types were obtained, it is often very difficult to ascertain from which particular
geological formation they were collected. The collection of types is now in the
Museum of the University of Bonn. As far as I can make out, about one dozen
new Carboniferous Lamellibranchs are figured and described, but several of those
of other authors are refigured from German examples.
1840. Sedgwick and Murchison’s paper “ On the Physical Structure of Devon-
shire, and on the Subdivisions and Geological Relations of its Older Stratified
Deposits,” was read before the Geological Society on June 14th, 1837, and was
published in the ‘ Transactions of the Geological Society,’ vol. v, pt. ili, 1840.
It contains six plates of fossils, with descriptions by J. de Carle Sowerby; the
following Lamellibranchs being figured and described :
Posidonia lateralis
— Becheri, Goldfuss From Venn, near Barnstaple.
—_ — var. Goldfuss
— ___ tuberculata From Budle, Northumberland.
1 Some other species, referred to Modiola, Mytilus, and Avicula, have been determined as
Naiadites in my previous monograph.

1840. Hichwald’s paper, ‘‘ Die Thier-und Pflanzenreste des alten rothen Sand-
steins und Bergkalks in Novogrodschen Gouvernement,” was published in the
‘ Bull. scient. Acad. Imp. Sci. St. Petersbourg,’ t. vii, 1840. He enumerates the
following Carboniferous bivalves :
Nucula cardiiformis. Unio (Sanguinolaria) sulcatus, Phill.
Cardium exiguum. _ _— levis.
Pterinea levis (Bronn). Casts of a shell like either Pholadomya
Pecten tenuissimus. or Solen.
— Nox.
No plates are given, but a short description of each species.
In another publication, ‘Die Urwelt Russlands durch Abbildungen erliutert,’
the first part of which is dated in the same year, figures and descriptions are
given of Anodonta tenera, A. tenuissima, and Mytilus fragilis. The last has
deep concentric hollows, reminding the observer of Posidomomya vetusta, Sow.
But Eichwald does not appear very certain as to the real nature of the shell, for
he says, “ Sie steht allerdings dem Mytilus oder der Modiola zunichst, Kénnte
aber doch zu einer andem Gattung, vielleicht gar zu Anodonta gehéren, wenn sie
vollstandiger bekannt wiire die Zeichnung ist nur entworfen, um auf ihre allgemeine
Form aufmerksam zu machen.”
In a still later publication, ‘ Bull. Soc. Nat. Moscou,’ 1856, p. 565, he thinks
his M. fragilis identical with M. Teplowii (sic), de Vern., ‘ Paléont. de Russie.’
1841. In the first volume of the ‘ Transactions of the Manchester Geological
Society,’ 1841, is published Captain Thomas Brown’s paper entitled ‘‘ Description
of some New Species of Fossil Shells, found chiefly in the Vale of Todmorden,
Yorkshire,”’ with a plate of seventy-eight figures, fourteen of which are those of
Lamellibranchs. Six of these forms are referred to Catillus, and should now
be referred to Posidoniella, de Koninck. The shells were all collected by
Mr. Gibson of Hebden Bridge, in whose cabinet they are stated to be.
22 CARBONIFEROUS LAMELLIBRANCHIATA.
The following shells are described and figured :
Avicula obliqua. Catillus Kellyit.
— Samuelsir. Gervillia minor.
Catillus Kirkmant. ; Modiola Mooret.
— levis. — minuta.
— costatus. Cytherea antiqua.
— obliquatus. Artemis parva.
— minutus. Luecina dubia.
In 1841 another work by Prof. John Phillips, entitled ‘ Figures and Descrip-
tions of the Paleozoic Fossils of Cornwall, Devon, and West Somerset,’ was
issued by the Geological Survey ; but the bulk of the book is on Devonian remains,
and I can only make out that three species of Posidonia—P. tuberculata, P. Becheri,
P. lateralis—and twe doubtful forms referred to Sanguinolaria—sS. sulcata and
S. subelliptica—are from Carboniferous strata.
In 1842 Agassiz published a translation of Sowerby’s ‘ Mineral Conchology,’
but I have not been able to get access to a copy, and am not aware whether any
additions or alterations were made therein.
In 1842 de Koninck published the first of his two important monographs on
the fauna of the Carboniferous period of Belgium, entitled ‘ Description des
Animaux Fossiles du Terrain Carbonifére de la Belgique.’ He figures and de-
scribes eighty-one species of Lamellibranchiata, many of which were new,
belonging to sixteen genear. Reference appears to have been made to every
published work bearing on the subject, and several of the generic references of
previous authors are corrected. Fifty-one species and three genera are described
as new; the new genera being Myalina, EHdmondia, and Cardiomorpha, all of
which are still retained.
In 1842 Sir Richard Griffith issued a “ Notice respecting the Fossils of the
Mountain Limestone of Ireland, as compared with those of Great Britain, and
also with the Devonian System.’ The paper contains a brief account of the
lithological character of the beds included under the term Mountain Limestone,
and a table of the fossils showing the strata in which they occur in each of the
three Carboniferous Limestone districts of Ireland (Southern, Middle, and Northern
districts), contrasted with the occurrence of the same species in North Devon and
the British Mountain Limestone of England and Scotland.
1842. D’Orbigny, in his ‘Voyage dans l’Amérique Meéridionale,’ tom. i,
4me partie, 1842, described amongst others two new shells, Pecten Paredezii and
Trigonia antiqua from beds of Carboniferous age in Bolivia.
In the same year John Morris published a ‘Catalogue of British Fossils,’
enumerating all forms described from British strata to date. A second edition
appeared in 1854, with additions.
BIBLIOGRAPHICAL SKETCH. 23
1843. J. H. Portlock’s ‘ Report on the Geology of the County of Londonderry,
and of Parts of Tyrone and Fermanagh,’ was published by the Geological Survey
in 1843. There is a descriptive list of Carboniferous fossils, which are well
figured. Mention is made of forty-two species and two varieties belonging to
twenty-one genera, twenty species and two varieties being described for the first
time ; but they are all referred to well-established genera, though subsequent
investigation shows such reference to be not always biologically correct.
1843. It is possible that the shells figured by Captain Brown in the ‘ Ann. and
Mag. of Nat. Hist.,’ vol. xu, 1848, pp. 390 and 396, under the names Pachyodon
Gerardi and P. pyramidatus, really belong to Schizodus ; but, as all the types have
disappeared, this reference founded on the appearance of the figures alone is
uncertain.
In 1844 a letter to the editor of the ‘ Annals and Magazine of Natural History’
from Professor King appeared in that periodical, informing him that he had
been ‘‘ compelled to institute six new genera,” in a ‘ Monograph of the Invertebrate
Fossils of the Magnesian Limestone of the County of Durham,’ “namely,
Allorisma for Sanguinolaria sulcata, Philips . . . . Schizodus for the Permian
and Carboniferous Axinus.”
1844, The new genera and species by Sir R. Griffith were named and figured
by F. M‘Coy in his great work entitled ‘A Synopsis of the Characters of the
Carboniferous Limestone Fossils of Ireland;’ but the list of names in Griffith’s,
‘Notice’ is somewhat different from that in the Synopsis; in some cases the
generic name is changed, and in others the specific ; and in addition the names of
fossils obtained from the Petherwin and other beds of North Devon are included in
the former list.
One genus (Pteronites) and sixty-one species in the list are marked as new, all of
which were subsequently described and figured.
‘The Synopsis of the Characters of the Carboniferous Limestone Fossils of
Treland,’ by M‘Coy, is the standard book of reference on British Carboniferous
Limestone fossils. One hundred and ninety-five species belonging to forty-eight
genera of Lamellibranchiata, six of which are new, are figured and described ;
in addition descriptions are also given of those forms occurring in Ireland,
which had been previously published. One curious point is to be noted in the
plates, and that is that the drawings have not been reversed on the stone, conse-
quently the opposite valve is depicted to that which is apparently shown. Many
of the types are in the “ Griffiths Collection” of the Museum of Science and Art,
Dublin, but unfortunately those which were in private collections have been lost
sight of. |
1844. Dr. Garner brought out his ‘ Natural History of Staffordshire’ in 1844; on
plate B he gives figures of Pecten ellipticus (interior), Inoceramus vetustus, and Pleuro-
24 CARBONIFEROUS LAMELLIBRANCHIATA.
rhynchus minae. In an appendix issued in 1860 are fuller lists of Carboniferous
Lamellibranchs from the county of Staffordshire.
1845. Morris furnished the chapter on the “ Fossil Mollusca of New South Wales
and Van Diemen’s Land”? in Strzelecki’s ‘ Physical Description of New South Wales
and Van Diemen’s Land,’ published in 1845. He enumerates and figures the
following species from rocks of supposed Carboniferous age:
Allorisma curvata. Orthonota ? costata.
Pachydomus cordatus, new genus = Mega- — compressa.
desmus, Sow., name previously occupied. Eurydesma, new genus.
Pachydomus antiquatus. Pterinea macroptera.
— cuneatus. Pecten Illawarensis.
—_— levis. | — limexformis.
_— globosus. — Fittoni.
carinatus. — squamuiliferus.
In 1845 Murchison, de Verneuil, and de Keyserling brought out ‘Le
Géologie de la Russie d’Europe,’ in which several Carboniferous Lamellibrancha
are figured and described; fourteen species belonging to nine genera are said
to be new, namely :
Pecten ellipticus. Mytilus Pallasi.
— sub-fimbriatus. Pinna Ivaniskiana.
— Sibericus. Schizodus Rossicus.
— Bouei. Unio Hichwaldianus.
— Valdaicus. Cardium Ouralicum.
Avicula sub-papyracea. Sanguinolaria Rimert.
Mytilus Teplofi. Solemya Biarmica.
In 1846 de Keyserling published his ‘Petschoraland,’ with figures and
descriptions of four Carboniferous bivalves, only one of which, Pecten subclathratus,
was new.
De Ryckholt’s ‘ Mélanges paléontologiques,’ the first part of which is dated
1850, and the second part 1853, seems to be the next important work on
Carboniferous Mollusca to appear. The names of the new species are all dated,
and vary from 1847 to 1853. Fortunately there will not arise any question of
precedence of names on this account, for few publications on the subject appeared
about this time. In Part I thirty-six new species and one new genus (Phola-
domya) of Carboniferous Lamellibranchiata are figured, the description of the
latter being found in Part II, where fifty-six new species and three new genera
of bivalves—Anomianella, Scaldia, Omalia—from Carboniferous beds are defined
and depicted. The figures seem to have been somewhat idealistic when com-
pared with those of the same specimens published in de Koninck’s great work.
BIBLIOGRAPHICAL SKETCH. 25
1846. In the ‘ Bulletin de la Société Géologique de France,’ tom. iii, 1846,
de Verneuil gives a list of fossils from the Carboniferous beds of Asturias collected
by Paillette. No new species are described and no figures are given. The lists
contain the following Lamellibranchs from the Terrain carbonifére, de Pola de Lena :
Cardium voisin du ©. rostratum, de Kon. (C. elongatum, Sow.).
Nucula tumida, Phill.
/
1847. A paper by M‘Coy, “On the Fossil Botany and Zoology of the Rocks
associated with the Coal of Australia,” appeared in the ‘ Annals and Magazine of
Natural History,’ vol. xx, for 1847, p. 298, et seq., the following new Lamelli-
branchs are described, good figures being also given:
Pecten ptychotis. Pachydomus pusillus.
— sub-quinquelineatus. Cardiania exilis.
Inoceramus Mitchellit. Notomya (new genus).
Pleurorhynchus australis. — securiformis.
Modiola crassisima. _ clavata.
Pachydomus gigas. Pullastra? striatocostata.
— sacculus. Venus ? gregaria.
- ovalis.
1849. In the memoir of the United States Exploring Expedition of 1849
Prof. Dana published the figures and descriptions of a numerous suite of fossils
from beds of Carboniferous age in New South Wales, amongst which were many
forms of Lamellibranchiata. None of the shells are recognised as belonging to
British or Huropean forms. The work previously done by Morris and M‘Coy is
acknowledged by the author, who from the text appears to have also previously
published some account of fossils from South Australia. The new genera
Astartilia and Maeonia, with its allied groups Pyramia and Cleobis, are defined, and
the genus Pachydomus of Morris is accepted.
1849. In the ‘ Monograph of Permian Fossils of England,’ by King, published
as the volume for 1849 by the Palzeontographical Society, the new generic name
Allorisma’ is given to include shells hitherto known as Myacites, Schlotheim,
Hiatella, Fleming, Sanguinolaris, J. de C. Sowerby, Unio, id., Lutraria, Goldfuss,
Pholadomya, Morton, Sanguinolites (pars), M‘Coy, and Orthonota (pars), Salter.
This genus was supposed to possess a sinus in the pallial impression, and the
original of the specimen figured, which is in the Museum at Newcastle-on-Tyne,
has a fine pallial sinus in ink. This character is denied by M‘Coy, and is
certainly absent in all the shells from Redesdale which show the interior as a cast.
It is probable that some markings due to other causes were mistaken for the sinus,
1 There is evidently a misprint in the name on the page giving the explanation of pl. xi
(op. supra cit.), where it occurs as Allerisma.
A
26 CARBONIFEROUS LAMELLIBRANCHIATA.
and it is impossible now to judge from the original specimen, as the pen which
gave that specimen the sinus has probably left scratches in the supposed
situation.
In the same volume the genus Edmondia, de Koninck, is re-defined, and some
internal characters of that genus described and figured, the type taken being from
the Redesdale Ironstone beds of Lower Carboniferous age. Other than these two
cases no further mention is made in the work of Carboniferous remains.
In 1849 Captain Thomas Brown issued his ‘ Atlas of the Fossil Conchology of
Great Britain and Ireland,’ a work in which were reproduced the figures of all the
fossil Mollusca hitherto published in Great Britain. Several new Lamellibranchs
from the Coal-measures are described in the volume, but curiously enough none
of M‘Coy’s new genera or species seem to have been known to the author. A
brief description and the locality of each fossil are also given. The publishers
brought out a reproduction of the plates of this work with a much abbreviated
letterpress in 1889, and, unfortunately, adopted none of the revised generic names
which had come into vogue in the interval between the editions. ‘he plates are,
however, from the same steel plates, and are therefore identical with those of the
original.
1850. D’Orbigny’s ‘ Prodrome de Paléontologie’ bears the date 1850, but all
species given on his authority are dated 1847. 282 species of Lamellibranchs
from Carboniferous strata belonging to nineteen genera are enumerated with
reference to the author of each and the locality where it occurs.
1851. In the ‘Annals and Magazine of Natural History’ for the year, sec. ii,
vol. vu, p. 157, is a paper by M‘Coy entitled “ Description of some New
Mountain Limestone Fossils,” with a full account of his new genera, Streblopteria
and Aviculopecten, and a figure of the internal cast of a member of the latter;
and two years later, in 18538, in the same serial is another paper, ‘‘ On some New
Carboniferous Limestone Fossils,” with descriptions of four new shells. This
description was literally repeated with figures in that author’s greater work
published in 1854-6 in conjunction with Adam Sedgwick, entitled ‘ British
Paleozoic Fossils.’ This is a great work, containing much new matter as to
classification, several new orders and families being defined, and many old
families, genera, and species being re-described. Figures are given of the New
Carboniferous fossils described in the ‘ Annals and Magazine of Natural History’
for 1851, just quoted, together with others,—in all twenty species belonging to
seven genera; but no new form is described in the work.
In the plates to this volume the lithographer has not reversed the drawings on
the stone, so that the opposite valve is apparently shown to that from which the
drawing was made.
The following genera and species are figured :

Limestone and Lower Carboniferous Rocks of the Fifeshire Coast from Burnt-
island to St. Andrews,” before the Royal Society of Edinburgh, subsequently
published in vol. xxii of the ‘ Transactions’ at p. 385.
Lists of fossils are given from the Limestone beds described, and three figures
are given of a ‘strong handsome Schizodus ” from drawings furnished by
Mr. Salter.t. It is stated that Fleming thought this shell was identical with Anatina
attenuata, M‘Coy. They occur in countless masses in a bed south-east of
Kingsbarns, and from near Colinton.
1860. In the Palzontological Notes, p.11, by Mr. Bailey in the ‘ Geological Survey
Memoir,’ “‘ Explanation of sheet 143, Ireland, illustrating parts of the counties
of Clare, Kerry, and Limerick,” 1860, a figure is given of a new shell, Myalina
Foynesiana, which occurs with Aviculopecten and Posidonomya, but no description
appears. At p.19in the same memoir, figures and description of another new
shell, Lunulacardium Footi, from basal shales of the Coal Measures of Rosscliff,
co. Clare, are given. Jn 1862 the same author in the Paleontological Notes of the
Memoir explaining sheet 127, illustrating portion of Queen’s County, figures at
p- 9 (figs. 2 a—e), Leda attenuata, Sanguinolites plicatus, Solenopsis pelagicus,

In 1861 appeared the first edition of Hull’s ‘ Coal-fields of Great Britain,’ which
contained a plate on which was a figure of Aviculopecten papyraceus ; and later
editions with a somewhat altered plate appeared in 1873 aud 1881.
In 1861, in the Memoir of the Geological Survey, “‘ Iron Ores of Great Britain,”’
pt. ii, ‘‘ The Iron Ores of South Wales,” Mr. Salter gives a plate with figures of
Schizodus carbonarius, Hdmondia wvoniforms, and Myacites sulcata from the
Rosser veins, and a short list of other marine Lamellibranchs from the ‘same
horizon. This number contains the original description of that author’s genus
Anthracomya, and illustrations of Anthracosia (Carbonicola) and Anthracoptera
(Naiadites).
The next year, in the Geological Survey Memoir, ‘ The Geology of the Country
round Wigan,’ with the definitions of the new genus Anthracoptera, and a figure
of Anthracosia (Carbonicola) robusta, Mr. Salter gives a figure of Posidonia
Gibsoni, Brown. The generic reference is doubted, and it is stated that ‘‘a new
generic name will in all probability be required.”
In 1864, in the Memoir ‘ On the Geology of the Country round Oldham,’ the same
writer figures Aviculopecten papyraceus, A. fibrillosus, n. sp., and Ctenodonta, sp.
indet., from concretions in shales about 150 yards over the Great Mine Coal,
Ashton-under-Lyme.

1865. In vol. xiv of the ‘Smithsonian Contributions to Knowledge’ for
1865 is a memoir entitled “ Paleontology of the Upper Missouri: Invertebrates,”
by Meek and Hayden. A new arrangement of the genera allied to Avicula is
proposed, pp. 27, 30, and 51, thus:
PTERIIDA = AvicuLip2.
1. Pteriniine.—* Cartilage apparently occupying a series of linear furrows,
ranging more or less nearly parallel to the cardinal margin in a usually broad,
flattened cardinal facet or area. Anterior muscular scar sometimes moderately
developed and deep.”
Pterinia, Myalina, Ambonychia, and probably <Actinodesma, Gryphorhynchus,
Eurydesma, and several undefined Paleozoic groups.
2. Ptertine (or Aviculine).—‘ Cartilage mainly or entirely confined to a single
more or less defined depression or cavity behind the beaks. Anterior muscular
impression very small.”
Pteroperna, Pteria (or Avicula), Margaritifera, Malleus, Aucella, and Eumicrotis ;
also probably Monotis, Halobia, Pteronites, and Posidonomya.
36 CARBONIFEROUS LAMELLIBRANCHIATA.
3. Meliwine.—* Cartilage divided and distributed along the hinge in a series
of furrows crossing the cardinal area at right angles to the hinge-line. Anterior
muscular scar generally very small.”
Crenatula, Melina (= Perna, Brug. not Adanson) Bakevellia, Gervillia, Inoceramus,
and Pulvinites.
The affinities of Myalina are discussed, and its close resemblance with
Dreissena noted; two forms, M. perattenuata, M. and H., and M. subquadrata,
Shumard, are figured and described. |
The Family Crassitellide is made to include a large number of dissimilar
genera. The Carboniferous genera, Pachydomus, Carbonicola, Pleurophorus, are
placed with Astarte, Crassitella, Cardinia, and many others.
Pleurophorus is stated to be identical with Cleidophorus, Hall, and Plewrophorus
occidentalis, Meek and Hayden, is redescribed and figured from the Coal-measures
of Nebraska.
Under the family Anatinide, with Thracia, Pandora, Pholadomya, and other
recent genera, are grouped Cercomya, Anthracomya, Allorisma, Myacites,
Chenomya, Arcomya, Mactromya, Goniomya, Gresslya, Cardiomorpha, Ceromya,
Sedgwickia, Sanguinolites, and probably Cleobis, and some species of Orthonota;
a Classification which cannot be retained for one moment, on anatomical and
structural reasons. Allorisma subcuneata, Meek and Hayden, is redescribed and
figured. The genus Sedgwickia is defined and discussed. S.? Topekaensis,
Shumard, and S.? concava, Meek and Hayden, are described and figured. The new
genus Chenomya, Meek, is defined ; and Chenomya? Leavensworthensis, M. and H.,
equals Allorisma ? Leavensworthensis, M. and H.; and C. Cooperi, M. and H.,
equals Panopxa Oooperi and Allorisma ? Cooperi, M. and H.
1866. Geinitz’s work on the ‘ Carbon-Formation und Dyas in Nebraska,’ was
published in 1866. The following Lamellibranchs are described, and some of them

‘ Proceedings of the Chicago Academy of Nat. Sciences,’ p. 11, called ‘‘ Descriptions
of Paleozoic Fossils from the Silurian, Devonian, and Carboniferous Rocks
of Illinois and other Western States,” pp. 13—20.
The following new species are described from Carboniferous beds :

at pp. 170 and 327 a long critical review, by Meek, of Geinitz’s, ‘ Upper Palzeozoic
Rocks and Fossils of South-eastern Nebraska.’ Nearly all the specific names of
the fossil shells are challenged, and many of the genera.
1868. In vol. iii of the ‘Geological Survey of Illinois,’ ‘Geology and
Paleontology,’ Messrs. Meek and Worthen describe and figure—
Pernopecten Shumardianus, Winchell ? | the Kinderhook group of Burlington,

Lithophaga lingualis, Phillips ?
Allorisma (Cheenomya ?) hybrida, M. and W.
* The name Parallelodon is proposed as a substitute for Wacrodon, because the latter had been
in use since 1862 for a genus of fishes

States,” by Meek and Worthen, pp. 70, 71. In this contribution only two
Carboniferous Lamellibranchs are described, both new, one belonging to a new
genus, Chenocardia, C. ovata and Allorisma costata. The diagnosis of the genus
Chenocardia is given, and at p. 72 the generic name Prothyris is proposed for a shell.
1869-87. The first edition of the ‘Geological Survey Memoir’ on the Lime-
stone District of Derbyshire was published in 1869. It contains a list of fossils
gathered from various localities; pp. 174—179 of the 2nd edit., 1887.

Basin of Dalry,” with lists and localities of fossils.
1871. Two papers by Meek occur in the ‘ Proceedings of the Academy of
BIBLIOGRAPHICAL SKETCH. 39
Natural Sciences of Philadelphia’ for 1871. In the former, entitled ‘‘ Description
of New Species of Invertebrate Fossils from the Carboniferous and Devonian
Rocks of Ohio,” pp. 57, &c., the diagnosis of the following Lamellibranchs from
the Waverley group of the Carboniferous series is given :
Aviculopecten crenistriatus. | Allorisma (Sedgwickia?) pleuropistha.
_— (Streblopteria ’) Hertzeri. | Grammysia ? rhomboides.
Sanguinolites ? obliquus. = ventricosa.
The second paper is entitled ‘‘ Description of New Species of Fossils from
Ohio and other Western States and Territories,” pp. 159, &c., and contains
descriptions of—
Pterinea (Pteronites ?) Newarkensis, Schizodus subtrigonalis,
Cypricardina ? carbonaria, Allorisma Winchelli,
Schizodus Medinaensis, — ventricosum,
—all from the Waverley group of strata.
1871. On May 24th, 1871, J. Logan Lobley read a paper on the “ Principal
Features of the Stratigraphical Distribution of the British Fossil Lamellibran-
chiata,” in which he gives tables and diagrams indicating the number of species
of each family of Carboniferous Lamellibranchiata then known from British
strata; ‘Quart. Journ. Geol. Soc.,’ vol. xxvu, pp. 411—418. He enumerates
eighteen genera with 403 species. In Tables 11 and ii he gives 398 species, 282
of which belong to the Asiphonide, and 116 to the Siphonide.
1871-6. In 1871 Messrs. Young and Armstrong prepared an elaborate
catalogue of the Carboniferous Fossils of the West of Scotland, which was
published in 1871 as an appendix to vol. i of the ‘ Transactions of the Geologica]
Society of Glasgow.’ This was published as a separate volume in 1876, on the
occasion of the visit of the British Association to Glasgow. One hundred and
twenty-five species are enumerated, belonging to twenty-nine genera, and a long
and full list of the localities where each species is found is also given. Nothing
new is described.
1871. Vol. i of the ‘ Palwontologia Indica’ (Memoirs of the Geological
Survey of India), ‘The Cretaceous Fauna of Southern India’ by F. Stoliczka,
published in 1871, contains a synoptical list of the families and genera noticed
in the volume. In it the Carboniferous genera of Lamellibranchs (Pelecypoda)
published up to that date are entered with the type-species, recent and fossil.
They are grouped in ten orders and forty-six families. Critical notes are also
given. Further researches have, however, in certain cases shown the error of
some of these references.
1872. Meek’s ‘‘ Report on the Paleontology of Eastern Nebraska” forms a part
40 CARBONIFEROUS LAMELLIBRANCHIATA.
of the ‘ Final Report of the United States Geological Survey of Nebraska,’ which

In many cases the generic names of the original authors are revised.
1872. Mr. W. H. Baily read a paper before the Royal Geological Society of
Ireland on April 12th, 1872, subsequently published in vol. xiii (vol. iii, new
series) of the Journal of that Society, entitled ‘‘ Remarks on the genus Plewro-
rhynchus, with a description of a new species. He shows that the genus ranges
from the Caradoc-beds to the Carboniferous Limestone, eight species being from
the latter formation. He gives figures and descriptions, p. 25, pl. iv, figs. 1 a—d, of
Plewrorhynchus Koninckii, which occurred in the Lower Limestone near Rathkeale,
co. Limerick, and states that the name was recorded at the Meeting of the British
Association in Dublin as early as 1865.
The contribution of Mr. R. Etheridge, jun., to the Paleontology of the
Carboniferous series are many and valuable, and extend over a series of years,
commencing in 1872 to 1882. It will be convenient to mention all these papers
in series, giving the date of each.

Map of the Geological Survey of Scotland,’ published in 1872, the preface
dating 1871. It consists of a stratigraphical list and table of the fossils found in
the district comprised, with the map showing the horizons at which the several

—making a grand total of 310 new species.
Of the whole number of species described 262 are stated to be more or less
rare, and 35 species are founded on single or incomplete specimens. Seven new
genera are instituted for species which had previously been referred to some
already described.
1886. A full and copious list of the fossils of the Carboniferous series in
Northumberland is contained in chap. xiv of the ‘‘ Materials for a Paleontology of
Northumberland,” of Professor Lebour’s ‘ Outlines of the Geology of Northumber-
land and Durham,’ second edition, 1886, pp. 108—128. The fossils are given in
lists from each bed, but no new species are described ; several have only the genus
indicated, the species being new or not determined.
1887. In the second edition of ‘ The Geology of the Carboniferous Limestone,
BIBLIOGRAPHICAL SKETCH. ol
Yoredale Rocks, and Millstone-grit of North Derbyshire,” ‘Mem. Geol. Sury.,’
Appendix I, is a list of the Carboniferous Limestone fossils, revised and added to
by G. Sharman and EH. T. Newton. A table is given in parallel columns showing
the various localities at which each fossil occurs, but no horizons are indicated.
A special column is given to the occurrences of the fossils in the Carboniferous
Limestone of Staffordshire for the sake of comparison. No new forms are noted.
1888. On the 8th of December, 1887, John Young, LL.D., read a paper before
the Geological Society of Glasgow, published in the ‘Transactions,’ vol. viii,
part 1, 1888, p. 291, entitled “ Notes on the Scottish Carboniferous Genera of
the Molluscan Family Anatinide.” He refers Myacites, Leptodomus, Sanguino-
lites, Hdmondia, and Cardiomorpha to this family, and he discusses at some length the
affinities of each. The genus Sedgwickia, though not occurring in Western-
Scottish Carboniferous beds, is also mentioned and referred to the same family.
He remarks on the large number of species which have been described and named,
and thinks that a careful review would very greatly curtail the list.
1888. A complete list of the genera and species of British Carboniferous
Lamellibranchs, with, in certain cases, synonyms, is contained in the ‘ Fossils of the
British Islands; ’ vol. i, ‘* Paleozoic, with Appendix brought down to end of 1886,”
by Robt. Etheridge, sen. No localities are mentioned, but references are given in
almost every case. No new species or genera are described.
1888. In the ‘ Proceedings of the Academy of Natural Sciences of Philadelphia’
for 1888, is a paper by C. R. Keyes, “On the Fauna of the Lower Coal-measures
of Central Iowa.” Nine Lamellibranchs are enumerated, pp. 2832—4, but no new
ones are described.
1889. In S. A. Miller’s ‘ North-American Geology and Paleontology,’ dated
1889, is a brief classification of the American rocks, including the Carboniferous,
and a full list of the Paleozoic fossils of North America, arranged with their genera
and species alphabetically, under the sub-kingdoms, with the synonyms printed in
italics. Whenever possible a woodcut is given of the type species, and references
are given to the original publication in which each species was described or figured.
A previous volume was published in 1877 by this author, entitled ‘The American
Paleozoic Fossils.’ This work is quoted by de Koninck.
1890. Mr. John Ward, in his paper on the ‘‘ Geology of the North Staffordshire
Coal-fields,’”? ‘Transactions of the North Staffordshire Institute of Mining and
Mechanical Engineers,’ vol. x, gives lists of the marine Lamellibranchs which occur
in two bands, one above the Gin Mine or Golden Twist Coal, and the other above
the Bay Coal of Longton; and also notes Aviculopecten papyraceus from Yoredale
and Coal-measure beds, A. alternatus, A. fibrilosus, and Posidomonya Gibsoni,
from Yoredale beds, and Schizodus from below the Four-foot Coal, Werrington.
Anthracomya lanceolata is erroneously described as Modiola lithodomoides,

p. 180, and a description by R. Etheridge, sen., of a new shell, Sanguinolites
granulatus, is given with a figure, p. 127, pl. i, fig. 12.
1891. In a paper “On some Hstheriz and Hstheria-like Shells from the
Carboniferous Shales of Western Scotland,” in vol. ix, p. 85, of the ‘ Transactions
of the Geological Society of Glasgow,’ read on March 13th, 1890, T. Rupert Jones
refers certain shells from Arden, near Glasgow, and Dalry, Ayrshire, which he
had previously described as Hstheria punctatella to Posidonomya.
1890. Vol. vii of the ‘ Geological Survey of Illinois ’ contains A. H. Worthen’s
descriptions (pp. 107—133) and the figures of numerous Carboniferous Lamelli-
branchiata which had been recorded in ‘ Bulletin of the Illinois State Museum
of Natural History,’ No. 2,1884. The following species have been named mostly
by Worthen; those described as new are marked.*

1891. On December 8th, 1891, Mr. George Wild read a paper before the
Manchester Geological Society, subsequently published in the ‘ Transactions ’ of
that body, vol. xxi, 1892, p. 364, on “The Lower Coal-measures of Lancashire :
Organic Remains, Sections of Seams, and Probable Mode of Formation.” At the
end of this paper is a catalogue of fossils, in the cabinet of the author, from the
Lower Coal-measures of the North and Hast Lancashire Coal-field. Figures are
given, pls. 11 and i, of the following Lamellibranchs :

Nucula, sp.? (Schizodus.) | Solemya primexva.
Anthracosia, new angular species. (Schizodus.) | Aviculopecten.
Posidonia Gibsoni.
1891. In the ‘ Proceedings of the Academy of Natural Sciences of Philadelphia ’
for 1891, p. 242, is a second paper by C. R. Keyes, on “‘ Fossil Faunas in Central
Iowa.” Several Lamellibranchs are enumerated from Carboniferous beds, but no
new forms are described.
1892. In the ‘ Proceedings of the Royal Physical Society of Edinburgh,’
vol. xi, p. 244, is a paper by J. G. Goodchild, entitled ‘‘ Notes on Carboniferous
Lamellibranchs,” in which he coufirms the fact that the Nuculoid shells from
Carboniferous beds possess a distinct cartilage-pit, and therefore cannot be
referred to Ctenodonta, Salter. He also points out the absence of a pallial sinus
in some of these shells.
Another paper, at p. 245, in the same volume deals with the genus Allorisma,
a diagnosis of which is given, and it is stated that a pallial sinus is seen in at least
SIX species.
1892. Professor W. Amalizky’s work, ‘‘ Ueber die Anthracosien der Permfor-
mation Russlands,”’ in ‘ Paleontographica,’ Band xxxix, 1892, p. 125, et seq., deals
only with fresh-water forms, which he classes under the following genera :
Carbonicola, M/‘Coy. Oligodon, Amalizky.
Anthracosia, King. Naiadites, Dawson.
Paleomutela, dmalizky.
1892. Professor X. Stainier’s paper, ‘‘ Matériaux pour la flore et le faune du
houiller de Belgique,” published in vol. xix of the ‘ Aunales de la Société Géologique
de Belge,’ 1892, p. 333, gives tabular lists of the localities and horizons at which
fossil Lamellibranchs are found, many marine forms being included. A second
note on the “ Faune du Houiller’’’ was issued in the volume for 1892-3, tome xx,
p- 43; and a third note was published in the ‘ Bulletin Société Belge de Géologie,
&c.,’ tome vil, 1898, p. 135, with further details of the occurrence of Carboniferous
Lamellibranchiata in the Belgian coal-bearing strata.
1894. In a paper, “ Ueber die systematische Stellung der Trigoniden und
die Abstammung der Nayaden,” by von 8. Frh. V. Wéhrman, in the ‘ Jahrbuch
der k.-k. geologischen Reichsanstalt,’ Band xl, for 1893, the affinities of
Schizodus (p. 7), Paleomutela (p. 16), and Palxoneilo, p. 18 (Tellinomya), are
discussed. |
1893. Vol. vii, ‘ Report of the Geological Survey of Ohio,’ contains, chap. i,
a section on the ‘‘ Paleontology of Ohio,” by R. P. Whitfield. Pinna Mazvillensix,
Allorisma Andrewsi, and Allorisma Mazvillensis are here figured and redescribed.
’
54 CARBONIFEROUS LAMELLIBRANCHIATA.
Chap. iv consists of ‘‘ Observations upon the so-called Waverley Group of
Ohio,” by Prof. C. L. Herrick. Lists of fossil Lamellibranchs are given from
various horizons of this group, and figures of thirty-three new forms are given
without a word of description.
1894. Mr. J. F. Whiteaves described and figured some new large Coal-measure
fossils as Asthenodonta Westoni from the South Joggins. They much resemble
Anodonta Jukesti from the Kiltorean beds in size and appearance (‘ Proc. and
Trans. Roy. Soc. Canada,’ vol, xi, sec. iv, p. 21, 1894).
1894. In the ‘Proceedings of the Royal Physical Society of Edinburgh,’
vol. xii, p. 356, is a paper by Mr. Goodchild, entitled “ Notes on Carboniferous
Lamellibranchs,” which was read on March 21st, 1894. He discusses the generic
affinity of Venus parallela, Phillips, and refers it to Cypricardella, Hall. In the
latter part of his paper he discusses the bathymetrical distribution of the
Carboniferous Lamellibranchs.
1894. Part 2 of vol. v of the ‘ Geological Survey of Missouri’ contains a section,
chap. xii, on ‘* Carboniferous Lamellibranchs,” by C. R. Keyes. Many species are
redescribed and refigured, and the following new form is described and figured—
Aviculopecten fasciculatus. A valuable list of spurious and doubtful species is given
at the end.
Some Additional Publications and Papers.
1868. Figures of Avicula and Nucula? from the Coal strata, without specific
names, are given at p. 833 of the ‘Geology of Pennsylvania,’ vol. ii, pt. 2, by
G. H. D. Rogers.
1868. In vol. ii, p. 81, of the ‘ Transactions of the Academy of Science of
St. Louis’ is a second paper by Swallow, entitled ‘‘ Descriptions of some New
Fossils from the Carboniferous and Devonian Rocks of Missouri,” in which the
following Carboniferous Lamellibranchs are described for the first time:
Allorisma antiqua. | Cypricardia ? occidentalis.
Cypricardia ? Pikensis. | Pecten Broadheadii.
— ? Wheelerv. | — Missouriensis.
— ? Shumardiana. Avicula magna.
1884, An important work, ‘lhe Natural History of New York: Paleontology,’
vol. v, part 1, 1884, by James Hall, contains descriptions and figures of Lamelli-
branchs of the Devonian age. Although not referring directly to Carboniferous
fossils, some of the new genera established by the author have been adopted by
L. de Koninck in his great work on the ‘Cualcaire Carbonifére de Belge,’ viz.
Cypricardella and Leiopteria.
1892. In the ‘Seventeenth Annual Report of the Department of Geology, &c.,
MODIOLA. 55
Indiana,’ pp. 701—704, pl. xx, figs. 1—10, S. A. Miller describes and figures from
Carboniferous beds—

Cypricardella Gorbyi, n. sp. Grammysia Blairi, u. sp.
Aviculopecten sculptilis, nu. sp. Conocardium Indianense, n. sp.
DESCRIPTION OF SPECIES.
Family MYTILIDA.
Shells elongate, wedge-shaped, narrow, and tumid anteriorly, expanded and ,
flattened posteriorly. Pallial impression entire. Adductor muscle-scars two or
more in each valve.
Observations.—The family Mytilide were well represented in paleeozoic times,
several well-defined genera having already come into existence.
M‘Coy, ‘ British Pal. Fossils,’ p. 265, classed together a number of genera
under the family Mytilide, which have not, however, been generally recognised
as having much affinity by subsequent investigators. For instance, his family
Mytilide includes Mytilus, Lithodomus, Modiolopsis, Dreisena, Hippopodium,
Pinna, Dolabra, Myaphoria, Anodontopsis, Lyrodesma (Actinodonta), Clidophorus,
Tellinomya, Orthonotus, and apparently (p. 499) Edmondia. This very hetero-
geneous group cannot be retained. ‘The same author refers the genus Myalina
with Ambonychia to the Aviculide, and this classification is accepted by many,
but I advance reasons for placing these two genera in the Mytilide, though in
certain characters they have a slight affinity with the Aviculide.

Generic Characters.—Shell oblong, transversely triangular, inequilateral, equi-
valve, obliquely swollen, gibbose in front, compressed behind and above. The
hinge-line is straight, equalling in length about one half the long diameter of the
shell. The umbones are obtuse and not very conspicuous, anterior but never
terminal. The hinge is edentulous; ligament internal, attached to an elongated
depression within the margin of each valve. Muscle-impressions obscure, three
in each valve,—one anterior, one posterior, and one below the hinge-line.
Observations.—Many Carboniferous Mytiliform fossils have been grouped
under the genus Modiola.
Phillips records four distinct forms :—Modiola squamifera, which belongs to
a genus in the Arca family; M. lingualis, which for anatomical reasons I have in
this work referred to Lithodomus ; M. elongata, which I believe to be the same
shell as those which I now refer to Posidoniella, de Koninck ; and M. granulosa,
all trace of which has been lost, and from the meagre description and poor
drawing it is impossible to identify the shell.
Sowerby referred one species of Naiadites from the Coal-measures of Coal-
brookdale to this genus, to which it is very closely allied in external form.
Portlock described Modiola Macadam, three varieties, and M. subparallela
from the Carboniferous shales of the north of Ireland. The former group, in
which I recognise two distinct forms, I am retaining in this genus; the latter shell,
owing to the discovery of the hinge-plate in a specimen in the Belfast Museum,
from Ballycastle, I refer to Anthracomya.
M‘Coy, in addition to species previously described by other authors, described
four new forms from Irish Carboniferous beds,—Modiola concinna, M. divisa,
M. megaloba, and M. patula, Of this M. concinna should be probably referred to
Parallelodon. M. divisa also has not the appearance of the genus, and at present
I am uncertain as to its real affinity. There is a well-developed posterior ear, a
longitudinal groove parallel to the hinge-line, and a curious lineal constriction in
the anterior part of the shell (compare Avicula Hendersoni, R. Etheridge, jun.,
‘Quart. Journ. Geol. Soc.,’ vol. xxxiv, p. 11, pl. i, fig. 11). I have retained the
two species Modiola patula and M. megaloba, though the types of both are absent
from the Griffith Collection in the Museum of Science and Art, Dublin.
MODIOLA. 57
; Captain Brown described and figured a large number and variety of shells
under the name Modiola, quoting the references of previous writers. He included
several forms of Anthracomya in that genus.
De Ryckholt included all the Mytiliform shells from the Carboniferous beds of
Belgium in the genus Mytilus; of these M. Cordolianus, M. fabalis, M. apici-
crassus, and M. palmatus are referred to Modiola by de Koninck.
Baily referred a specimen from the Carboniferous shale of Foynes Island to
Myalina, but I have not been able to retain it in this genus, as the shell has
not a striated hinge-plate, and possesses an anterior lobe. I have considered this
term as a synonym of M‘Coy’s Modiola iwegaloba.
De Koninck described and figured eighteen species of Modiola in his great
work (op. cit., pp. 174—180), four of which had been described previously by
de Ryckholt as Mytilus (mentioned above), and one by himself in a previous work
as Cardiomorpha. The new species are—
Modiola princeps. Modiola gibberosa.
— fusiformis. — reniformis.
— laeryma. — macrocephala.
— wimpressa. —— cuneiformis.
— Meeki. — spathuliformis.
— arguta. — Ff annulosa.
— ? emaciata.
On careful examination of the whole series of specimens now in the Natural
History Museum, Brussels, I am convinced that M. princeps and M. fusiformis are
the same shell as M. lingualis, now referred to Lithodomus, and I am doubtful
whether the Modiola Cordoliana may not also belong to the same species. The
type is somewhat crushed, and this may account for the flatter and more expanded
posterior end. The test is well preserved, and this may account for the accentua-
tion of the lines of growth. A second specimen has even a closer resemblance
to the British form.
Of the remainder, the types of three, M. arguta, M. cuneiformis, and M. Meeki,
do not appear to be in the collection. MM. apicicrassa, de Ryckh., appears to me
to be in too fragmentary a condition to be recognised and to serve as a type, and
I doubt, with de Koninck, whether Modiola annulosa is correctly referred to that
genus. WM. fabalis gave me the idea that it was the young of Posidoniella vetusta,
which it most resembles in the undulations which ornament its surface.
Whether or not the shells which I still retain in Modiola are correctly
referred to that genus may be considered somewhat doubtful in the absence of any
knowledge of the internal anatomy of the shell.
Portlock’s Modiola Macadami, var. lata, has a curious internal ridge, which
passes downwards from the umbo to the inferior border in the anterior part of
8
58 CARBONIFEROUS LAMELLIBRANCHIATA.
the shell (which is shown as a groove in casts). This is a feature not usually met
with in the genus Modiola, but is seen in other Carboniferous bivalves, e. g. the
Avicula Henderson of Robert Etheridge, jun. M‘Coy’s Modiola divisa also had
this peculiar structure, and the specific name was given to it on that account ; but
I have, however, stated above that I consider it probable that these two forms
will be found to be the same.
Only four Carboniferous shells have been referred to Modiola by American
paleontologists, two of which, in aformer Monograph, I thought probably belonged
to Naiadites.
Many of the elongate, narrow, Modioliform shells occurring in the Jurassic
beds agree rather in shape with Lithodomus than with Modiola, to which they have
always been referred, it having been the custom to place all such shells in the
latter genus. Probably this has been due to the desire to establish the rock-boring
habits of a shell before classifying it with a group in which that mode of living is
characteristic. Habits, however, are a matter of environment and evolution, of
course depending on anatomical construction, but should not, I think, be used as
a basis for classification.

Specific Characters.—Shell transversely elongate, obliquely spathulate, obliquely
eibbose. ‘The anterior end is almost obsolete and obtusely pointed. The lower
margin, convex in outline at first, soon becomes slightly concave, until the oblique
convexity of the shell meets it, when it again becomes convex downwards. The
posterior border is obtusely rounded, and there is no angle at any part of its
extent, but it meets the lower margin with a more obtuse curve than it makes
above with the superior border. The hinge-line is almost straight, and equal in
length to almost one-half the extreme antero-posterior measurement of the shell ;
posterior to the hinge the upper border gently curves downwards, aud passes
imperceptiblyinto the posterior.
The umbones are anterior but not quite terminal, small, remote from the
MODIOLA PATULA. 59
edge of the shell. The surface of the shell is divided into two portions by an
_ oblique swelling, which passed downwards and backwards from the umbo to the
lower margin near its junction with the posterior border. The lower edge of this
swelling is the most marked, and is almost angular in its middle and posterior
portions. Below the swelling the shell is compressed and hollowed, so that this
part of the surface is placed at a considerable angle with the rest of the shell.
The byssal notch was probably at the centre of the lower border, judging from the
constriction on the surface of the shell. Above the swelling the shell arches by a
gradual curve into the upper and posterior borders, the curve being very rapid in
front, and gradually lessening trom before backwards, the convexity of the shell
diminishing at the same time, but with the smaller convexity the valves become
expanded from below upwards.
The interior is at present unknown.
The exterior is marked by numerous fine lines of growth, starting from the
anterior end, where they are much crowded, but becoming rapidly and widely
separated as they pass backwards over the shell, the anterior ones being as much as
half an inch apart, but the distance between each line gradually diminishes from
before backwards. The interspaces are filled with very fine lines, so that the
markings appear to be subimbricate, from the separation of the secondary lines of
growth into bundles by the primary. All the bundles and lines of growth have
the same contour as the margins of the shell, and when they reach the upper
border are rapidly crowded together and terminate in the hinge-line. The shell
appears to be very thin.
Dimensions.—Fig. 2, Pl. I, measures—
Antero-posteriorly 80 mm.
Dorso-ventrally 40 mm. estimated in incomplete specimen.
The left valve is 20 mm. deep.
Localities —The Carboniferous Limestone of Cork, Millicent.
Observations.—The original specimen from which M‘Coy described this species
was probably in the collection of Dr. Haines, of Cork, as the words “‘ communicated
by Dr. Haines, of Cork,” are appended to the description. At any rate the
specimen is not in the Griffith collection in the Museum of Science and Art,
Dublin. The specimen I figure is now in the collection of Mr. Joseph Wright, of
Belfast, who informs me that he obtained it from the collection of Dr. Haines.
It cannot be the original of M‘Coy’s figure as is obvious from the most
cursory comparison; it is satisfactory, however, that the specimens now figured
come from the same locality as the original. M‘Coy points out that “the broad
spathulate form and want of posterior angle . . . . distinguish this from
every other Palzeozoic species.” This is so, at any rate, as far as Carboniferous
species are concerned, all the others having a more or less angulated posterior
60 CARBONIFEROUS LAMELLIBRANCHIATA.
border; but in addition the surface-marking is very typical. The subimbricate
appearance and demarcation of the lines of growth into bundles is not met with in
any other species. |
The original specimen is smaller than the one I figure, measuring only about
60 mm. in its antero-posterior diameter, and the anterior end is enveloped in
matrix; but it shows the characteristically shaped posterior end, and the sub-
imbricated, widely separated primary lines of growth dividing the secondary
lines into bundles.
There is a well-marked specimen in the Griffith Collection of the Museum of
Science and Art, Dublin, evidently named by M‘Coy, and doubtless forming part
of the material on which he founded the species, for that there was more than one
specimen is at any rate probable, because, although the anterior end of the figured
Specimen is not exposed, he states, ‘‘ Anterior end forming an obtuse lobe before
the beak.” It was not M‘Coy’s practice to give more than one figure of
any of his species, and he seldom gives more than one view of any specimen,
except mere outlines to show contours, or magnified drawings of surface
ornamentation.
It is a matter of regret that at present no specimens have been met with which
reveal any details of the hinge-apparatus or muscular scars.
I think it very probable that Mytilus pernella of de Ryckholt belongs
to M‘Coy’s Mod. patula. The peculiar surface-marking is faithfully depicted in
de Ryckholt’s figures, and the general tumidity of the shell is well indicated.
His description is ‘‘ Coquille épaisse, allongeé, ovale, un peu arquée, renfiée; sa
surface est couverte de gros plis saillants, inégalement espacés, sur lesquels
passent de fines hgnes d’acroissement, &c.”’ This species, obtained from Visé, is
not, however, noted or even given as a synonym by de Koninck in his last work,
and it is probable that the shell on which the description was based has entirely
disappeared.
This species would appear to have a very local distribution, being only known
from the Carboniferous Limestone of the south of Ireland, and, if my surmise is
correct as to the true character of M. imacrocephala, very rarely in Belgium in
stage ii of the Carboniferous Limestone.

Specific Characters.—Transversely and ovately triangular, of moderate size.
The anterior portion of the shell is represented by a small tumid lobe, well marked
off from the rest of the surface by an oblique constriction; the anterior border is
bluntly rounded, and passes by a gradual curve into the inferior border, which is
directed obliquely downwards and backwards, and almost straight, making an
acute angle with the hinge-line. The posterior border is obliquely truncated above
and rounded below in young specimens, but in larger ones less truncate and more
rounded.
The hinge-line is straight, equal in length to quite two-thirds of the greatest
length of the shell, and joins the posterior border at an obtuse angle. ‘The
umbones are anterior, swollen, acute, but not raised above the hinge-line, apparently
contiguous, not terminal. Proceeding backwards and downwards obliquely from
the umbones is a gibbosity, narrow but convex, transversely at first, but expand-
ing as it passes downwards, and in the lower third it becomes flattened. ‘lhe
anterior slope of this ridge is rapid, and it is bounded in front by the sulcus which
marks off the anterior part of the shell, the sulcus being almost linear above, but
becoming broader and deeper as it approaches the margin, and having an oblique
direction. Posteriorly and upwards the shell is gradually compressed and
expanded into its borders.
The Interior.—The hinge-line is non-striate, and has the indication of a longi-
tudinal groove for an internal ligament just within the hinge-edge. The anterior
adductor muscle-scar is small, deep, and marginal below ; and in front of the beak
the posterior adductor scar is large, shallow, ovate, and 1s placed a short distance
from the margin at the posterior superior angle.
The pallial line is simple and remote from the margin. The internal surface is
almost smooth, but has, below and behind, obscure concentric sulci.
Eexterior.—The surface of the shell is covered with fine and close lines of growth,
which have a direction parallel to the borders. ‘The left valve is the more convex.
Shell thin.

Observations.—The original type of M‘Coy’s species has unfortunately com-
pletely disappeared, but the specimens which I refer to the same name now have
a very close resemblance to the original figure. Little can be made out from
M‘Coy’s description, which is self-contradictory and meagre. It is as follows :—
** Transversely ovate, gibbous, beaks small, subterminal. Anterior lobe exceeding
half the length of the shell, defined by a strong sulcus from the beak. Hinge-line two-
thirds the length of the shell, angulated.’ The italics are mine. The figure
does not show such an anterior lobe as here described, but apart from this curious
inaccuracy, the description tallies well with the shells now described, with the
exception that the Northumbrian specimens are much larger. ‘This shell appears
to be a true Modiola, having the groove for the internal ligament, and a rounded,
non-striate hinge-margin, thus differing from Naiadites, to which genus it has a
very great superficial resemblance ; indeed, it would be impossible to separate it —
from this genus, except from the hinge and internal characters, and the associated
fossils. The general shape at once separates it from Myalina. M/‘Coy says in
his remarks, “‘ This is one of the very few instances in which the true anteriorly
lobed, recent and Oolitic form of Modiola has been found in the older rocks.”
Fortunately the slab of limestone obtained by Mr. John Dunn, of Redesdale,
from the Coombs Quarry contains four specimens: one, an imperfect interior,
Pl. Il, fig. 8, happily just giving enough detail of the hinge-structure for
correct generic identification; one, a good cast, Pl. II, fig. 7, imperfect at
the anterior end; and two specimens, Pl. II, figs. 5 and 6, of left valves
showing surface markings and general shape, while another specimen, Pl. II,
fig. 9, shows the anterior end. An undoubtedly marine fauna is contained in
this bed of limestone. The Irish locality is not given in M‘Coy’s work, and I am
not at present aware of the occurrence of this species anywhere else in Great
Britain.
The example from Foynes Island, figured by Baily but not fully described,
named Myalina Foynesiana, is of the same species as the Northumbrian shells.
There are two examples on the same slab,—one, the cast of two valves, lying flat
open; the other, the interior of the shell. The striated hinge-plate and terminal
umbones of Myalina are conspicuously absent, so that the shell was incorrectly
referred to that genus. The anterior end is incomplete, but the casts of the
umbones are preserved, and have not the two processes representing the pit-scars
of Naiadites on them. The posterior adductor scar is very finely shown in this
specimen, Pl. II, fig. 10, which I am able to figure by the kind permission of the
Director-General of the Geological Survey, Sir A. Geikie. The specimen is in the
Collection of the Irish Geological Survey. This shell is associated in the shales
with Aviculopecten, Posidonomya, and Goniatites.

Specific Characters.—The shell is small but lengthened, narrow, and convex,
and must approach to a cylindrical form when both valves are together. Appa-
rently equivalve. The anterior end is almost obsolete, and has a bluntly pointed
extremity, moderately convex. The inferior border commences in front by curving
downwards from its junction with the anterior, and then becomes straight, making
with the hinge-line an angle of about 15°; then it passes into the posterior
border in a bluntly rounded curve.
The posterior part comprises by far the greater portion of the shell, and is
expanded and flattened. Its border is at first obliquely truncate from above
downwards and backwards, and then bluntly rounded to meet the inferior margin.
The hinge-line is straight, and equal to about half of the greatest length of the
shell in extent, forming behind a very obtuse angle with the posterior border.
The umbones are almost anterior, but apparently not quite terminal; very
inconspicuous. Passing downwards and backwards from the umbones is a very
gibbose oblique swelling, which becomes rapidly expanded and lost on the surface
of the shell as it approaches the postero-inferior angle, the upper border of the
swelling being the more accentuated, above which the shell is at once compressed
and expanded upwards.
The interior has not been observed.
Exterior.—The surface of the shell_is smooth, but under the microscope very
fine concentric lines of growth are apparent. Shell very thin.

Observations.—In the original description of the species Modiola Macadamii (op.
supra cit.) General Portlock gave names to three varieties, without enunciating
the specific characters or types. He states, p. 432, “The three forms figured
seem in themselves sufficiently distinct for specific separation, but there
are so many intermediate gradations, and so much variation from age and the
condition of the specimens that I shall unite them together as merely varieties of
one species.” In his remarks on M. Macadamii, var. angusta, he says, “ This
diverges as much from the ordinary form in one direction as fig. 15 (IM. Macadamii,
var. lata) does in another;” and this makes it appear that he regarded neither
of the three varieties as the specific type. This omission is unfortunate, as no
description or figure exists of such, and therefore it has been necessary to regard
Portlock’s variety angusta as the type, this form being the first one of the three
on page 432 of Portlock’s work. The block on which the figured specimen of J.
Macadamii, var. angusta, occurs is of totally different lithological character, and
contains a different fauna from those in which the other described varieties were
found,—the first-named shell occurring with a typically marine fauna, containing in
abundance Nuculana (Leda) attenuata, Avicula Hendersoni ? R. Etheridge, jun.
(Modiola divisa, M’Coy), and Ostracoda; while with the other varieties only some
other forms of Ostracoda are found. In the Explanatory Memoir of Sheet 25 of
the Geological Survey, p. 22, the shells are said to occur with Spirorbis, Helodus,
Leperditia Okeni, and plant remains; and in two others with Orthoceras,
Euomphalus Cyrtoceras, and Syringopora.
Iam of opinion that this form is specifically distinct from the other two ; both from
the general appearance and the associated fossils, which indicate a more truly
marine condition. From the fact that in most of the localities the shells were of
estuarine or brackish-water habitat, it seems to me probable that the vars. /ata and
elongata were associated with them; and that the form angusta only occurred in the
true marine beds.
I have therefore retained the name Modiola Macadamii for the variety angusta,
and shall describe the other forms under the names Modiola lata, owing to a pre-
occupation of the name M. elongata by Professor Phillips (‘ Geol. Yorkshire,’ part 2) :
I can see no essential difference between them.
Immediately after the description of the three forms of M/. Macadamii, Portlock
described another form as Modiola subparallela, on which he remarks, “ Though this
MODIOLA LATA. 65
appears so very distinct a form from MJ. Macadamii, I am disposed to think that
they all merge one into the other ; but for the advantage of distinguishing the shell
in other localities I have separated this variety, so strongly marked, as a distinct
species.” The figures given are all very good, and fortunately the original types are
all preserved in the museum of the Geological Survey, Jermyn Street. An
examination of MV. subparallela at once demonstrates the fact that this shell does
not belong to that genus, but from its general shape and contour closely resembles
Anthracomya (Salter), to which genus I have referred the shell, Pal. Soc. ‘ Mono-
graph on Carbonicola, Anthracomya, and Naidaites, Appendix, p. 177, 1896.
M‘Coy described only one form as Modiola Macadamii, stating in his remarks,
‘This is a very variable shell.” Unfortunately no figures were given, but from the
description that the shell was “ marked with rather distant, irregular, deep, concentric
strie,” it is probable that he considered Portlock’s var. elongata as the type, but
nothing is said on the subject ; and the form depicted by the terms “ transversely
ovate, gibbous,” can hardly be applied to the species under description, but he gives
M. angusta and M. subparallela as distinct species.

Specific Characters.—Shell transversely and obliquely ovate, moderately swollen,
especially in front. The anterior end is very short, regularly gibbose, and bluntly
rounded in front, with a narrow dorso-ventral diameter. The inferior border is almost
straight, and directed downwards and backwards, becoming bluntly rounded as it passes
into the posterior border, which is very obliquely truncate above but rounded below.
The hinge-line is straight, and equal in length to more than one-half the greatest
diameter of the shell. It forms with the posterior border a very obtuse angle, and is
raised behind. The umbones are anterior, blunt, but not terminal, remote from the
hinge-line, from which they are separated by a distinct fold, which is narrow
in front and becomes wider behind. The shell is obliquely swollen, the swelling
becoming gradually expanded and flattened as it passes from before backwards,
the upper edge being acute for a short distance from the umbo; above this

swelling the shell becomes compressed rapidly into the hinge-line. There appears
to be no constriction anterior to the swelling, nor any indication of a byssal sinus in
the type specimen, which has the test preserved, but this character is markedly
present in casts.
Interior.-—The anterior adductor scar is almost marginal, fairly large and round,
quite anterior to the umbo. It is bounded behind in casts by a deep groove which
passed downwards and obliquely backwards to the lower border, becoming shallower
and broader en route. In casts the umbo is separated from the hinge-line by a
distinct hollow, which expands and becomes shallower as it passes backwards.
The interior of the umbo was smooth and acutely pointed. The positions of
the posterior adductor and the pedal muscle-scars have not yet been exposed.
There is no groove along the hinge-line as in casts of Anthracomya, nor area for
the internal ligament as im recent Modiole.
Exterior.—The surface is marked with fine raised thread-like striz, fresh ones
arising over the greatest gibbosity of the shell by bifurcation or intercalation.
Posteriorly they are fewer, less raised, and farther apart, and often joining another.
The direction of the striz is parallel to the margins, and they all terminate in the
hinge-line. On the flattened and compressed part of the shell above, and posterior
to the umbonal swelling, the surface is almost smooth. The shell is thin.

Localities.—Derry, Ballynascreen, Tyrone; Lower Limestone-shales, Cultra,
co. Down.
Observations.—Owing to the preoccupation of the name Modiola elongata by
Professor Phillips, though that shell is a Posidoniella, I have been unable to
retain it as the specific title of Portlock’s shell. I am, however, not able to find
any specific characters on which to separate Portlock’s variety of Modiola Macadamia,
var. elongata, from his var. /ata, and have therefore retained that name for both
shells. The apparent differences between the two types are due to the fact that the
var. elongata possessed a well-preserved test; while var. /ata, being a somewhat large
shell, was mainly a cast, but unfortunately did not give much detail as to the internal
anatomy; this want, however, was fortunately supplied by another specimen in
the Geological Survey Collection, Pl. II, fig. 27, which showed many of the internal
characters. One curious feature is the deep byssal groove in casts, all evidence of
which is absent in the complete shell. This is shown to be due to an oblique ridge
on the inner surface of the shell in fig. 28, Pl. II, from the Cultra beds. Portlock
MODIOLA TRANSVERSA. 67
speaks of his var. /ata having “a flattened form, probably the result of pressure.”
This flattening is only apparent and not real, and is due to the larger size of the
shell and the smooth surface of the cast.
This shell has somewhat the appearance of Anthracomya, from which it can be
separated by the absence of the groove parallel to the hinge-line in casts.
There is also a superficial resemblance to Naiadites, from which it is separated
by the absence of the characteristic pit-like, triple, anterior muscle-scars and the
striated hinge-plate.
When young the shells are not so oblique, and are in proportion to their size
more tumid, and have the anterior end more developed relatively to the rest of the
shell, Pl. Il, fig. 24. There is a fine slab from the Portlock Collection in the
Geological Survey Museum, Jermyn Street, showing this species in all stages of
growth ; even when very young the internal ridge is conspicuous. |
This species seems to be, as far as is at present known, confined to the Lower
Limestone-shales of the North of Ireland, and to be associated with Leperditia Okeni,
Helodus, and plant remains. It is doubtful whether it is therefore of marine
habitat, and in this particular differs very markedly from Modiola Macadamii, which
occurs with undoubtedly marine shells (vide antea, p.64). The litholugical character
of the shales in which the two forms occur is very different, Modiola lata being
found in brittle and soft marly shales, hght grey in colour. De Koninck, in the
remarks on his shell Modiola macrocephala, ‘Faune de Calcaire Carbonifére de la
Belgique,’ p. 178, says of his species, ‘‘ Elle a quelque ressemblance avec la Modiola
Macadamii, var. lata, de J. E. Portlock, mais elle en differe par sa grande taille et
par sa forte épaisseur.” The Belgian shell is so very much larger than the Irish
specimen, measuring 70 mm. in length, 43 mm. in height, and 30 mm. in thickness,
that | think there can be no connection between the two forms. De Koninck’s
species is founded on a single specimen from the Limestone of Waulsort.
MopioLa TRANSVERSA, sp. nov., Hind. PI. II, figs. 11, 12.
Specific Characters.—Shell small, transversely compressed, ovate, gibbose. The
anterior end is small and obtusely rounded, the narrowest part of the shell dorso-
ventrally. The inferior margin, directed backwards and slightly downwards, is
straight, joining the anterior and posterior margins at either end with a regular
blunt curve. The posterior border is regular and almost semicircularly rounded.
The hinge-line is straight, equal in length to about two-thirds of the antero-
posterior diameter of the shell. The umbones are small, anterior, pointed, and
directed inwards, downwards, and forwards; not elevated above the hinge-line.
Proceeding obliquely downwards and backwards is a blunt gibbosity, not well marked
off from the rest of the shell. The swelling is most marked above. About the
68 CARBONIFEROUS LAMELLIBRANCHIATA.
centre of the inferior border an almost obsolete, broad, shallow constriction is visible.
Behind, the shell is gradually compressed, especially above, and slightly expanded.
Interior.—The anterior adductor scar is large, marginal, situated just below and
in front of the umbones, from which it is separated by a sulcus. The posterior
adductor scar is round, and placed high up just below the termination of the hinge-
line. In the cast there is an elongate sulcus along the edge, corresponding to a
slight thickening in the edge of the shell, and no indications of striation.
Exterior.—-The surface is covered with fine striz and plice of growth more or
less parallel to the contour of the shell.

Pl. Il, fig. 12, measures 19 mm. 10 mm. _
Pl. 1b fig tt - 16 mm. 9 mm. 6-5 mm.
Locality.—In calcareous bullions in a bed of shale, several yards below the base
of the Millstone-grit, Congleton Edge.
Observations.—I am unable to refer these little shells to any described species,
and have therefore described them as new. They come from a bed described by
the Geological Survey officers in the Memoir entited ‘The Geology of the Country
round Stockport, Macclesfield, Congleton, and Leck,’ p. 72, where a section is given
showing the succession of Millstone-grit, Yoredale beds, and Carboniferous Lime-
stone, the quarry being nearer the upper part of the so-called Yoredale beds. The
Modiole are associated with a large and typical marine fauna—Productus, Chonetes,
Orthis, Streptorhynchus, and with other Brachiopods, Lamellibranchs, Gasteropods,
and Cephalopods. The species now described approaches MM. Macadami, but is
more transverse and tumid, and has a longer hinge-line.
The two specimens, on which the species is founded, consist of (fig. 12, Pl. II) a
cast of a left valve showing the muscle-scars and contour of the shell with a small
portion of the shell below; and (fig. 11, Pl. IL), a semi-decorticated specimen of
both valves which has lost the thin fragile portion of the shell next the posterior
superior angle, and therefore at first sight appears to be of different contour from the
cast, this being due to an accident in extracting the specimen from the matrix.

a distinct but small lunule. The anterior border, starting above at the most
anterior point of the shell, immediately descends with a regular curve posteriorly,
and passes imperceptibly into the inferior border, which is straight and directed
obliquely downwards and backwards. The posterior border is obliquely truncate
downwards and backwards in its upper half, bluntly rounded below, where it passes
with a regular curve into the inferior border.
The hinge-line is shghtly arched with convexity upwards, equal in length to
one-half the greatest oblique measurement of the shell. The umbones are tumid,
anterior but not terminal, pointed and directed forwards, contiguous. The posterior
or greater portion of the shell is obliquely swollen, the gibbosity extending down-
wards and backwards to the posterior inferior angle ; above the swelling the shell is
compressed and expanded, being quite flat and thin at the posterior superior angle.
Interior unknown.
Exterior.—The shell is almost smooth above, but very fine striz are visible, and
towards the ventral edge slight shallow folds, which become fine lines at the posterior
border above.

Observations.—I am, so far, aware of only one specimen of this species from
Great Britain, which I have, with hesitation, referred to WW. emaciata of de Koninck,
described by J. Fraipont (op. supra cit.). A number of small species of Modiola
are described by these authors, which are stated to differ from each other in series in
a few small details of size and shape. MV. emaciata is said to resemble MW. impressa,
de Koninck, more than any other, but this shell is “‘ plus longue et moins haute
vers l’extrémité postérieure.” Both shells come from Visé, stage 3, and are said to
be very rare ; and it might turn out, if many specimens were obtained, that they were
only varietal forms of the same species.
The shell figured is from the Manchester Museum, Owens College, the authorities
of which I have to thank for permission to describe the shell.

Specific Characters.—Shell oblique, transverse, gibbose, so as to be almost cylin-
drical, anteriorly expanded and rounded posteriorly. The anterior portion of the shell
is almost obsolete, and below the level of the umbones is swollen with bluntly rounded
border. The inferior border descends at first backwards and downwards with a
gentle curve; it then becomes sinuous, and posteriorly is more convex where it
passes with a regular curve into the posterior border, which is expanded and rounded.
The hinge-line is straight, and passes insensibly into the posterior border in a gentle
curve. There is no indication of an angle. The umbones are tumid, blunt, non-
contiguous, and directed forwards, situated very much forwards but not terminal.
There is a very small and almost obsolete lunule in front of them. Proceeding
downwards and backwards from the umbones the valves are much inflated
obliquely, immediately anterior to which is an oblique constriction, becoming
broader and deeper as it approaches the margin of the shell. Above the con-
striction the valves are compressed so as to become hollowed, the posterior superior
angle of the shell being expanded.
Interior.—No details of the muscle-scars are to be seen on the specimens which
have yet been obtained.
Exterior.—Certain portions of the left valve of fig. 5, Pl. VII, show the shell
to have been ornamented with fine concentric lines of growth, crowded in front.

Observations.—The specimens figured were obtained by me when I was
examining the coast sections of the Calciferous Sandstone beds of Fifeshire. They
are quite unlike any other member of the genus Modiola described from British
Carboniferous beds, and are distinguished by the regularly rounded posterior end
and tumid form. From the description and figures I have referred them to M.
higonula, a species described by de Ryckholt from “argile carbonifere” of Tournay.
His description is ‘ médiocrement renflée, meme un peu déprimée & l’extrémité
anale; .... cdté buccal rétréci et tronqué ; cdté anal allant en slargissant et
arrondi en avant; cdté palléal un peu baillant; crochets presque terminaux.” I[

think it is very probable that the shell described from the same bed by this author
as Mytilus fabalis is a slightly smaller specimen of the same species, the description
and figures resemble the former very closely. De Koninck only adopts the latter
species, which he says is founded on a single valve, a right one; but de Ryckholt
figures a left valve, and also gives a view from above of a bivalve example. De
Koninck figures a right valve with a very rounded posterior border, which is stated to
be “Véchantillon-type décrit par ce paléontologiste”” (de Ryckholt). The description
of MW. ligonula coming before that of MW. fabalis must therefore be adopted, if I am
correct in my surmise that the two species are identical.

expanded and somewhat compressed posteriorly. The anterior end is very short,
extending very slightly in front of the beaks, and it is very narrow from above
downwards. Its border is obtusely rounded, passing with gradual curve into the
inferior border, which descends slightly and is convex downwards in its anterior
and posterior thirds, and straight in the middle third. The posterior border is
obtusely and regularly rounded. The upper dorsal margin is nearly straight,
gradually rounding into the posterior end. The umbones are small, tumid, much
incurved, and twisted forwards, encroached upon in front by a wide, deep, cordate
lunule, and are situated in the anterior one-tifth of the shell. The valves are evenly
swollen, most so in front and along an undefined line passing from the umbones
downwards and backwards, the tumidity becoming gradually less to a point
anterior to the junction of the inferior and posterior borders. Shell convex, but
somewhat compressed along the inferior border and at the posterior superior angle.
Interior.—In casts the hinge-line appears to be simple. The anterior adductor
muscle-scar is shallow and round, situated well within the margin of the shell in the
deep hollow below the lunule, and extending inwards. The posterior adductor scar
is also at some distance from the posterior margin and is large, oval, and shallow, and

near the dorsal margin. The pallial line is entire, remote from the margin, and
extends posteriorly for some little distance beyond the posterior adductor scar, its
upper limb returning forwards to terminate in the posterior inferior corner of the
scar.
Exterior.—The shell is very thin, and is ornamented with irregular fine excentric
lines of growth oblique to the long axis of the shell, crowded and more conspicuous
in front, becoming more widely separated and at the same time less distinct as they
pass over the more tumid portion of the shell. Towards the lower margin and
behind, these are crossed by very fine radiating striz. Near the posterior extremity
of the valves the markings become almost obsolete. On the surface of casts the
markings on the interior of the shell show similar characters.

Localities —England: The Limestone of Lowick, Northumberland, and the

Ireland: Carboniferous Limestone of Killogunra, Killala.
Observations.—This species was described by M‘Coy, under the genus Litho-
domus, from a fine series of specimens obtained from the Lowick Limestones by the
Rev. L. Jenkinson. Having some doubt as to the correctness of this generic reference,
I asked Mr. Edgar Smith, of the Conchological Department of the British Museum
(Natural History Branch), to look at the specimens. He kindly wrote me as
follows: “ At first sight I regarded the enclosed as true Lithodomi, but a com-
parison with that genus hardly justifies that opinion. The form is different, and
Lithodomus does not exhibit regular radiating lines. The subgenus Botula has
similar prominent umbones, but the general shape of the shell is different. There
is a group of Modiola, including M, glaberrima, D. Kr.; M. arborescens, Chemnitz ;
M. elegans, Gray, with which your shells might, I think, be associated.” I have
therefore referred this species to the genus Modiola, but I must confess that I felt
very doubtful as to this species belonging to the Family Mytilide at all until I was
thus reassured by Mr. E: Smith. I know of no specimens of this shell except those
in the Woodwardian Museum, Cambridge; and I have to thank the authorities for
the loan of a fine series for examination, and also for permission to re-figure the
type specimen, Fig. 1, Pl. VIII. The shell is, however, mentioned in the Survey
lists as occurring in the Middle Limestone of Wensleydale. This species differs from
all other Carboniferous Modiolas yet known in shape, the possession of well-marked
umbones, with a distinct anterior lunule; the distance of its anterior adductor

Generic Characters.—Shell equivalve, transversely elongated, subcylindrical,
inflated. Anterior extremity rounded; the posterior rostrated or cuneiform.
Cardinal border straight, subparallel to the inferior border. Umbones very
anterior, not terminal, inconspicuous. Hinge edentulous. Ligament marginal,
thin, subinternal ; muscle-scars very faint. Shell of two layers; the inner nacreous,
the outer tubular.
Observations.— From the general shape and the position of the ligament I have
thought it well to separate Phillips’s Modiola lingualis from Modiola, and to place it
with Lithodomus dactyloides, M‘Coy, although there is no evidence that either
species were rock-borers. Messrs. Meek and Worthen were evidently of the same
opinion when they named a shell which they thought might be identical with
M. lingualis, Phillips, “‘ Lithophaga.”
Fischer, in his ‘ Manuel de Conchyliologie, gives Lithophaga (Bolten, 1798) and
Lithophagus (Megale von Mithlfeldt, 1811) as synonyms of the Lithodomus of Cuvier,
which was invented in 1817. Mr. E. Smith, of the British Museum, informs me
that the name was only given in a sale catalogue.
The elongate, narrow, subcylindrical character of the shell has a far greater
resemblance to recent Lithodomi than to Modiola. In well-preserved specimens the
fine radiating sinuous markings to be seen on the anterior and lower part of the
shell of Lithodomus are visible in the Carboniferous forms. This is to be seen in
fig. 3, Pl. I, and is finely shown in M‘Coy’s drawing of L. dactyloides.

Specific Characters.—Shell very transversely elongated and slightly oblique, cylin- ©
drically flattened from side to side in front, but expanded and flattened posteriorly.
The anterior extremity is bluntly pointed and narrow, somewhat flattened towards
the ventral margin, but convex above. The veutral margin is convex at the anterior
and posterior thirds, but slightly concave in the middle third. The posterior
margin is formed by two convex lines meeting at an angle at a point a little
below the centre, the upper part having a wider and longer sweep than the lower.
The hinge-line is straight, and slightly longer than one-half the extreme length
of the shell, and passes into the posterior border almost imperceptibly. The umbones
are small and inconspicuous, obtuse, non-contiguous, very anterior, but not quite
terminal, not well defined from the rest of the shell in front. The valves are
regularly swollen in front, the greatest gibbosity being nearer the upper than the
lower border, The swelling is slightly oblique and diminishes, but at the same time
LITHODOMUS LINGUALIS. 75
expands upwards and downwards, as it passes backwards. Below the swelling
in the middle third of the valve there is a broad shallow constriction corre-
sponding with the concavity in the inferior border. The hinge-line of each valve
is depressed anteriorly, so that there is a concave surface between the umbones
of the opposing valves posteriorly; this widens out to become lost on the
posterior slope of the shell. In this way the edge of the valve commences
below the umbo and is directed downwards, but by a slow twist on itself it
gradually rises and becomes directed upwards posteriorly, where it comes
into close apposition with the corresponding portion of the opposite valve.
The left valve appears to have been more convex than the right. The shell is
very thin.
The internal character of the hinge is partially shown in a specimen in the York
Museum (PI. II, fig. 2). It appears to be edentulous, and the ligament to be marginal,
The anterior adductor scar is small, excavated, marginal, situated just below and in
front of the umbones. The posterior adductor scar is almost obsolete, and repre-
sented by a broad flattened area equidistant from the posterior superior and inferior
borders.
The Exterior.—The shell is ornamented with very fine, close-set lines of growth,
which are crowded in front, and, following the contour of the margins of the shell,
terminate in the hinge-line. As the lines separate in passing backwards, other fine
ones appear in between, and towards the ventral margin there are occasionally
deeper wrinkles dividing the strie into bundles ; but these are not continued far
posteriorly.

Localities—England: Carboniferous Limestone of Park Hill, near Longnor,
Narrowdale, Castleton, and Wensleydale. Ireland: St. Dooghlas, co. Dubline
Millicent, co. Cork ; and Clonmel. Scotland: Limestone, East Kilbride.
Observations.—I have arrived at the conclusion that many shells described under
various names by paleontologists really belong to one and the same species, and
conform readily to the figures and description given by Phillips for his Modiola
lingualis. The original is unfortunately lost, but there is a very well-preserved
specimen labelled M. lingualis in the Gilbertson Collection now in the British
Museum (Natural History), which may be taken as fairly typical, for it was
from the fossils collected by Mr. Gilbertson that Phillips drew many of his
types. The original specimen is said to have come from Castleton, where’I have
obtained others, which thus forge another link in the chain of identification. The
76 CARBONIFEROUS LAMELLIBRANCHIATA.
original description is “
from the beaks; lines of growth delicate, forming furrows on the convexity.”
Unfortunately little can be learned from the figure, which is that of a young
remarkably elongate, with a curved oblique convexity
example, and is less flattened at the sides anteriorly and more cylindrical than in
the adult, the posterior end being less expanded. M‘Coy, while referring to the
occurrence of MM. lingualis in Ireland, says ‘‘some obscure specimens of this shell
have occurred,” but gives no figures. He describes and figures a typical adult
example of what I consider to be Phillips’s shell, under the name Lithodomus
dactyloides. Unfortunately the original of this figure has disappeared, but there isa
specimen in the Griffith Collection in the Museum of Science and Art, Dublin,
which bears the name L. dactyloides, and this I take to be the adult and nearly full-
grown form of J. lingualis. This specimen is certainly of the same species as the
shells figured Pl. I, figs. 38 and 5, from Irish Carboniferous beds. M/‘Coy’s
description is as follows :—‘“‘ Width three times the greatest length, cylindrical,
extremities obtusely rounded ; beaks inconspicuous, close to the anterior end. Surface
marked by concentric lines of growth, which near the beak are decussated by very
fine, oblique, longitudinal striz.” It will be noted that in his figure the decussating
striz are shown over the greater part of the shell.
The specimen from Park Hill, Pl. I, figs. 4, 4 a, the original of Mr. R.
Etheridge’s Modiola lithodomoides, I regard as the adult and full-grown shell of
Phillips’s M. lingualis. This specimen is much larger than the shell figured by
Phillips, but equally fine specimens also occur at Castleton with examples of the
shell in various stages of growth. Most paleontologists have never given
sufficient attention to the changes in size and shape due to growth, but have
multiplied to a very great extent the number of species without any real excuse
for so doing.
Mr. R. Etheridge, jun., gave a very perfect and accurate description of this
shell from the specimen which I am able to reproduce by the kindness of Sir A.
Geikie, it being in the Museum of the Geological Survey, Jermyn Street.
Mr. Etheridge, however, omits to point out the subangulated posterior margin,
and I think confounds two different forms under one title. The Scotch specimens
from the neighbourhood of Beith, Ayrshire, possessing certain well-marked
characters, which in my opinion are of specific value, and the specific name of
lithodomoides must be retained for this shell. The Scotch shells are more
cylindrical, much smaller dorso-ventrally compared with the antero-posterior
diameter. The hinge-line is comparatively much longer than in L. lithodomoides
from English and Irish limestones, always equalling at least two-thirds of the
greatest length of the shell in extent ; and the elongated hollow trough formed by
the depression of the upper edges of the valves is only found in the Scotch forms.
The second figure given by Mr. Htheridge shows the greater length of the
LITHODOMUS LINGUALIS. 77
hinge-line, but no specimens which have come into my hands have the dorso-
ventral measurement anteriorly equal to that in his fig. 2, unless they have been
flattened and expanded by crushing.
In the measurements given Mr. R. Etheridge, jun., uses the term length for
dorso-ventral, and width for antero-posterior diameter.
This author refers to Lithophaga ? lingualis, of Meek and Worthen (op.
cit.), from the Keokuk group of the sub-Carboniferous series of [llinois and
Indiana, as apparently resembling his shell very closely. These authors state,
*‘ We are by no means satisfied that this is the species described by Phillips, but
prefer to refer it provisionally to that species, rather because we have been
unable to find any very reliable differences, than from any great confidence in its
exact identity.” They note that many of their specimens are much larger than
the one figured by Phillips. Judging from the figure given, I should think the
reference of the American specimens to L. lingualis correct.
A very fine series of shells, forty-five in number, named Modiola fusiformis, are
in the collection made by de Koninck, now in the Musée de l’Histoire Naturelle
of Brussels; several of them are figured in his great work (op. cit.). There is
a large amount of variation to be noticed in this series, the depth of the
posterior end and the comparative extent of the hinge-line differing slightly in
many of them. I have little or no doubt that these shells are identical with those
named M. lingualis and M. lithodomoides from British rocks, and have therefore
placed M. fusiformis, de Koninck, as a synonym of Phillips’s species. I have no
hesitation also in referring M. princeps, de Koninck, to the same species.
M. Fraipont, who is responsible for the sections on Modiola, says in his remarks
on this fine shell, ‘‘ Cette magnifique espéce s’éloigne de la plupart de ses
congénéres et surtout de la M. lithodomoides, R. Ktheridge, par ses proportions
et par sa forme générale.” The description would do very well for the British
shell, with the exception that it is stated “ bord ventral droit,” notwithstanding
that the figure shows a ventral border concave in its middle third. The approach
to angulation of the posterior border is neither described nor depicted, but the
type specimen shows this character very plainly marked. In fact, M. princeps
differs from the adult form of M. lingualis in no characters of specific value,
mere size in a single example being no sufficient indication for the creation of a
new species. There are, however, three smaller specimens mounted on the same
plaque as the figured specimen, also named M. princeps, which are no bigger than
the ordinary adult British forms.
The form M. Cordolianus, de Ryckholt, approaches very closely to the species
under description. It appears that only the type and one other specimen are in
the de Koninck Collection. The former is more expanded posteriorly and flatter
than in specimens of the same size of L. lingualis, but this may be due to the fact °
78 CARBONIFEROUS LAMELLIBRANCHIATA.
that the shell is a little crushed. he lines of growth are separated at intervals
by more deeply cut interruptions. The second specimen on the plaque has not
these distinctive characters, but I hesitate for the present to place M. Cordolianus
as a synonym of Lithodomus lingualis.

MopioLa LirHopomorDEs (pars), R. Etheridge, jun., 1875. Geol. Mag., dec. 2,
vol. ii, p. 241, pl. viii, fig. 2.
Specific Characters.—Shell transversely elongate, fusiform, almost cylindrical
in front, flattened and expanded behind, very slightly oblique. The anterior end is
obsolete. The umbones project in front of the rest of the shell, and are only very
slightly marked off from the anterior portion of the shell. The anterior border
is obtusely rounded and very narrow. ‘The ventral border is convex in front and
behind, concave in the middle third. In the middle and posterior thirds, near the
ventral border, the shell becomes bent on itself inwards at right angles, so as to
present a narrow inferior surface, the extreme edge of each valve being then
directed upwards, so that there is a narrow elongated trench, along the bottom of
which the valves come in contact. ‘The byssal opening is in the front part of this
trench, as in Modiola now inhabiting the Firth of Forth. The posterior border
is lanceolate, very obliquely truncate above, and obtusely rounded below, joining
the ventral border with a very obtuse curve. The hinge-line is straight, equal in
length to about two-thirds of the extreme antero-posterior measurement of the
shell; for the greater part of its extent depressed below the level of the valves, but
elevated above them where it joins the posterior border, into which it passes with
a very obtuse angle. The shell is convexly swollen in the anterior two-thirds,
especially above ; but below it is only slightly compressed into the ventral margin,
towards the middle of which the shell becomes broadly compressed, hollowed
more especially in the right valve. Behind, the shell is compressed, flattened, and
expanded. The umbones are anterior, elevated above the hinge edge, and remote.
From the upper edge of each a ridge proceeds directly backwards, between which
and the edge of the valve is an elongated concavity, which, commencing narrow,
becomes broader by encroaching on the valve, and then gradually approximates
to the central line to meet the edge of the valve, where it becomes the highest
part of the shell.
The interior is unknown.
Hxterior.—The surface is covered by fine and close striz and lines of growth.
Here and there towards the ventral margin one of the lines becomes accentuated
and raised a little above the level of the others.

Localities.—Carboniferous shale of Lower Limestone of Beith, Ayrshire ;
Loraburn, Glen Lora, and Lochwinnoch, Renfrewshire, from shale in the Lower
Carboniferous Limestone group.
Observations.—Originally described, with a specimen from Park Hill, near
Longnor, Derbyshire, as M. lithodomoides by Mr. R. Ethridge, jun. I have
thought it well to separate the Scotch specimens, as they possess certain distinctive
characters, such as a comparatively much longer hinge-line, greater gibbosity
compared to the dorso-ventral measurement; a deep, elongated hollow in each
valve between the edge of the hinge and the umbones and ridge proceeding
backwards from them; and they do not possess the typical posterior border of the
Park Hill specimen. I have been enabled by the kindness of Messrs. Craig,
of Beith, John Smith, of Kilwinning, James Neilson, Dr. John Young, of Glasgow,
and Dr. Hunter, of Braidwood, to examine a large number of specimens of these
shells; and though there is, as might have been expected, a certain amount of
variation of form, yet the general charactres and contour are fairly regular. The
distribution would appear to be very local, both horizontally and vertically. As far
as I can gather, this species is only met with in shale connected with the lowest
(Howrat, Auchenskeith, or Beith) Carboniferous Limestone in Ayrshire and
Renfrewshire.
This shell is alluded to at page 43 of the Explanation of Sheet 22, ‘Mem.
Geol. Survey, Scotland,’ under the name “ Lithodomus dactyloides, M‘Coy,” as was
pointed out by Mr. R. Etheridge in the original paper on this shell; a reference
which he considered erroneous, from the fact that the radiating lines of that
shell described by M‘Coy are not present in the species under discussion.
This species possesses one very marked and peculiar character in the elongated
hollow depression between the edge of the valves and the umbonal ridge, well
shown in fig. 8, Pl. I, and to an extent in fig. 6 a, Pl. I, which forms an
escutcheon, a character absent in other species of Lithodomus and in Modiola.
It is unfortunate that this shell always seems to occur with the test well preserved,
and no indications are to be seen of what conditions obtained within. The
ligament appears to have been marginal and inconspicuous.
80 CARBONIFEROUS LAMELLIBRANCHIATA.
LITHODOMUS CARBONARIUS, Sp. nov. Plate II, fig. 14—19.
Specific Characters.—Shell of moderate size, transversely ovate, lanceolate,
moderately convex, and somewhat oblique. The anterior end is narrow, very
small, with a bluntly rounded terminal border. ‘The inferior border is gently
convex in its whole extent, and slightly oblique downwards and _ backwards.
Towards the posterior end it rises again, and forms a blunt curve with the posterior
border, the convexity being downwards and backwards; above, the posterior
border is obliquely truncate, but becomes rounded below. The hinge-line is straight,
equal in length to about from three-quarters to two-thirds of the extreme length
of the shell. It joins the posterior border at a very obtuse angle. The umbones
are small and inconspicuous, hardly elevated above the hinge-line, very anterior,
but not terminal, marked off from the shell in front by a shght groove. The
valves are somewhat convexly swollen, more so above, and compressed and
slightly expanded upwards posteriorly. There is no ridge or keel.
Interior. —The anterior adductor scar is excavated, marginal, and rounded. The
posterior has not yet been exposed. The hinge-line is simple, shghtly thickened, and
edentulous ; bevelled at its lower edge for the insertion of an internal ligament.
Heterior.—The surface is ornamented with irregular plice and lines of growth
oblique to the long axis of the shell, and parallel with the borders. Shell thin,
covered with a periostracum.

Pl. II, fig. 16, from Randerstone, measures 25 mm. 9 mm.
Pl. Il, fig. 17, from Eskdale Pe 20 mm. 8 mm.
Localities.—Scotland, Limestone No. 5, Randerstone, Fife, Calciferous Sand-
stone series; Eskdale; ‘‘ Scorpion-beds,”’ Lower Carboniferous.
Observations—I know of no described fossil shells to which I can refer the
specimens obtained from Randerstone and Eskdale. Fortunately the slab from
the former locality has exposed on it two interiors, in which the hinge characters
have been observed. This is in the possession of Mr. J. Kirkby, of Leven, who
referred the shell to L. dactyloides, M‘Coy, in his paper ‘‘ On the Marine Fossils
in the Calciferous Sandstone series of Fife.” ‘Q. J. Geol. Soc ,’ 1880, p. 578.
The Randerstone shells have lost their outer coating and periostracum, and
appear smooth ; but the Eskdale specimens have this coating well preserved.
In the majority of the shells from the latter locality both valves are in contact
but lying flat open, and united by the ligament on the planes of sedimentary
deposit, pointing to the death of the animal prior to the entombment of the shell.
Specimens in this condition are found of all sizes, from that of a pin’s head to that
of the specimen whose measurements are given above.

THE MARWOOD AND PILTON BEDS
OF
NORTH DEVON AND SOMERSET.
In the year 1840, Sowerby described twenty-four Devonian species from the
beds of the Pilton Series; in 1841 Professor Phillips increased the number to
seventy ; and in 1852 M‘Coy added several species to the list.
Since that time I do not know that many new forms have been described.
Professor F. A. Romer in 1855 figured an Aviculopecten which appears to have
escaped the notice of English geologists; and in 1863 Salter described, without
figuring, a species of his new genus Curtonotus. Mr. Etheridge, in his list of
Devonian Fossils, has catalogued the names of several additional Continental forms.
The present attempt to revise this interesting fauna took its rise in 1890, from
a letter of my lamented friend Mr. Thomas Roberts, F.G.S., who drew my attention
to the rich collection made by Mr. ‘lownshend Hall, F.G.S., and now in the
Barnstaple Atheneum, of which Mr. Roberts prepared, but I do not think
published, a list. Soon afterwards I visited Barnstaple by the kind invitation of
Mr. Townshend Hall, and began the study of the fauna; and I desire first of all to
acknowledge the exceeding kindness with which he and other friends have helped
me in an undertaking which has proved much longer and more difficult than I then
expected. Nothing could exceed the kindness and courtesy with which the
authorities of the British Museum, the Museum of Practical Geology, the Wood-
wardian Museum, and the Barnstaple Athenzeum have permitted me the free use of
their fine collections, and in other ways assisted me; and to Dr. Henry Woodward,

F.R.S., Sir Archibald Geikie, F.R.S., Professor T. McKenny Hughes, F.R.S., Mr.
J. G. Hamling, F.G.S., and their colleagues my grateful thanks are due. To
Mr. Hamling and Miss Partridge, of Barnstaple, I am also under obligations for the
loan of specimens from their private collections, and for helping me to collect fossils
in the field; my friend Dr. Henry Hicks, F.R.S., has also visited many localities
with me, both collecting fossils and making observations, the result of which we
propose to give in the sequel. One day, while working in the Barnstaple Atheneum,
a gentleman, Mr. Porter, of Pilton, then unknown to me, invited me to see his collec-
tion, made through many years; and after showing me his fossils he presented
them to me, unsolicited, for the purpose of this work. The generosity of this gift
can best be acknowledged by referring the reader to the accompanying plates.
Professor Rupert Jones, F.R.S., Dr. Henry Woodward, F.R.S., Dr. J. W.

Mr. He TT; Newton, FURS: Mr: H. A. Allen, F.G:S., Mr. G.-C. Crick, 1.G.s2
and other kind friends have most kindly helped me in guiding me toward
the identification of certain of the species; and Mr. W. Rupert Jones, Sub-
Librarian of the Geological Society, has shown his usual kindness in helping me
to solve perplexing questions of bibhography. |
I regret that in the following descriptions 'so much has often to be left in doubt.
Many of the specimens available are casts, many fragmentary, many embedded in »
matrix, and very many distorted, and sometimes crushed completely out of shape.
Probably from such causes errors may in some cases have occurred. It is to be
hoped that these may hereafter be corrected through the discovery of more perfect
fossils. I can only claim to have done my best to be careful, and to have sought,
wherever it was possible, to identify specimens with previously described forms.
‘The present evidence, however, shows that the fauna of these beds is rich and
varied, and I believe that we have by no means yet reached the limit of the species
that occur in them.
I also regret that some of the localities given are necessarily vague.
“* Barnstaple’? and ‘ Pilton’’ must be taken as general terms, not indicating a
precise spot. Many of the older specimens in museums only bear such general
labels. Mr. Porter’s fossils were, I understand, for the most part obtained from
the immediate neighbourhood of Pilton, but the very richness of the collection
prevented me in most cases from learning the exact localities of the various
1 In the descriptions I have been accustomed to group comparisons with other species under the
title of “‘ Affinities.’ It seemed to me a convenient general term, under which points of likeness
might be noted without necessarily betokening relationship. As, however, some German authors
have criticised me for having sometimes compared species which have only a superficial resemblance,
it is as well to observe that I did so intentionally, and that I shall continue to do so wherever it may
seem advantageous.

specimens. On the other hand, the fossils collected by Mr. Hall, Dr. Hicks,
Mr. Hamling, Miss Partridge, and myself bear, as a rule, the accurate name of the
place of their occurrence.
It is proposed in the first place to attempt the elucidation of the species, and
after that to give the stratigraphical observations made by Dr. Hicks, Mr. Hamling,
and myself.

The only evidence of Vertebrates known to me from the Pilton Beds is a slab
containing a few crushed and scattered scales. As far as can be seen, these are
wide, flat, oval scales, marked by fine, close, rounded striations, which probably
curve parallel to the contour of the margins which are destroyed. The slab was
labelled ‘* Fish scales’ by the late Mr. Thomas Roberts, F.G.S., and on showing it to
Mr. A. Smith Woodward he confirmed this, considering that they are certainly the
remains of fish scales, but that, as their shape is quite lost, it is impossible further
to decide their character.
Locality.—The Strand, Ashford. <A single slab is in the Barnstaple Athenzeum.
Phillips figures an elliptic scale from Baggy Point, which appears to be
similarly ornamented, and may perhaps be identical.
The scales of Phyllolepis and Pentagonolepis' seem to be similarly ornamented.

4 DEVONIAN FAUNA.
The first, which is probably the central portion, contains fifteen narrow somites
with straight sides, which are perpendicular to the line of the back, each somite
measuring 7 mm. in height by 2mm. in width. The lower part of the somites appears
crossed by a double series of transversely oval concavities, and their front margin
seems raised and convexly rounded off at the bottom. To the base of at least
every fourth somite remains attached a long narrow appendage or swimmeret (?),
which is narrower than the somite, and seems so placed that the front of the
somite is in line with the front of its base; it is probable that each somite had a
pair of such appendages. These swimmerets (?) show slight signs of segmentation
(not visible in the figure), are about 7 mm. in length, slope shghtly backwards,
and are narrowly lancet-shaped, gradually tapering toward their extremities, where
they are rounded off in a blunt point, They are longitudinally bisected by a
slight median furrow (ridge in the cast) which traverses them from end to end.
The second portion is less distinct ; signs of segmentation occur, but they are
apparently oblique to the back, and there are indications of one or two incipient
swimmerets (?). Near to the posterior end the body is suddenly constricted by
short concavities both above and below, after which it widens out into a caudal
prolongation, which seems to consist of some rounded plates, one containing a
margined spot, and of a pair of short flapper-like appendages with three seg-
ments. The test appears to have been massive, and probably had a granular
ornament.
Size.-—The totallengthis57 mn. The lengths of the two remaining fragments
are respectively 23 mm.and 22mm. The width at the front end is 5 mm., close to
the tail 3 mm., and across the tail 7 mm. ‘lhe length of the first swimmeret (?)
is 7 mm.
Locality.—The only specimen is in the Barnstaple Museum, where it is placed
among the Sloly fossils; and the character of the matrix appears to indicate that it
came from the Lingula beds of the Sloly group.
Remarks.—This fossil is most perplexing and difficult to interpret. Mr. Thomas
Roberts, F.G.S., long ago suggested that it might be a spined Myriopod ; and, on
consulting Dr. Henry Woodward more lately, he made the same suggestion,
comparing it with Huphoberia ferox, Salter,’ reviewed by him with other Myriopods
in 1887.2, The difficulties, however, in the way of assigning it to Huphoberia are
—(1) there are no signs whatever of dorsal spines, the upper line of the body being
continuous and simple, and there being no scars on the somites to indicate sub-
dorsal spines; (2) there are no clear signs of dorsal plates overlapping two

CARIDERPESTES. 5
ventral plates; (3) the appendages, appearing only on every fourth segment,
are not proved to have existed on all the rest; and seem blade-like and formed
for moving in water; and (4) there is considerable evidence of a peculiar
extremity.
Scudder ’ certainly figures an example of Hu. armigera” which appears to have
appendages only on every alternate ventral segment, one dorsal segment covering
four ventral ; but he explains this by supposing the ventral segments to be really
only two divided plates. Moreover the genera Xylobius and Archiulus, though
placed in the same sub-order, do not seem to show any signs of spines.
The signs of segmentation in the appendages are obscure, but some of those
organs, as figured by Scudder,* seem so closely welded that itis quite possible that
in the present instance also segmentation really existed. A central longitudinal
line, similar to that which is strongly marked in our specimen, is described by
Scudder in some species of Huphoberia.
In our fossil the lower part of a few of the segments shows marks which,
although very indistinct, have probably significance. Within the straight front
margin of the plate the surface seems raised in an indented ridge, receding again
backwards at the base like the mullion of a window; and behind this are two ovoid
concavities, separated above by a horizontal ridge level with the angle of the
scallop or indentation.
Professor Rupert Jones points out some resemblance to it in Anomalocaris
Canadensis, Whiteaves,* which he thinks to be allied to Huphoberia. Whiteaves’s
figure shows ten segments, each with two simple appendages, and a caudal extremity
with three pairs of irregularly placed equal spines. Our species differs from it,
among other points, in having the segments much narrower, and the appendages
very much longer.
While, however, there is much reason for regarding this fossil as a Myriopod,
it bears some resemblance to the bodies of the Phyllocaride. The latter appear,
as a rule, much shorter, and their segments do not generally have appendages,
though in Nebalia itself the two last body-somites have tufted appendages.
Lastly, our fossil appears to be a marine organism, both because it probably
comes from some bed of the Lingula squamiformis series, and because the structure of
its appendages seems to show that they may have been natatory organs. While,
however, Myriopods are essentially terrestrial, Scudder shows that there is reason
to suppose that some at least of the Carboniferous forms were more or less aquatic.

Description. Carapace bivalved. Hach valve subcircular. Dorsal margin
straight, about three-quarters the length; front margin slightly curved; ventral
and posterior margins much curved. Margins (except the dorsal) bounded by a
sharp triangular elevated rim. Surface irregularly convex, divided into three
groups of swellings, which are approximately arranged as follows.—A line drawn
from the postero-dorsal to the antero-ventral point, and another from nearly the
antero-dorsal to the central point, represent furrows or deep concavities dividing
the test into three compartments, which we may call the dorsal, the anterior, and the
posterior compartments. The dorsal compartment is again divided by shallower
grooves into a long narrow hinder swelling, a broad central, and a minute anterior
swelling. The anterior compartment is indistinctly divided into a small anterior
swelling occupying the extreme antero-superior corner of the test, a large diffuse
pyriform swelling, and a minute hinder swelling occupying the posterior angle of
the compartment. The posterior compartment has one large diffuse swelling filling
it entirely, except its anterior part, which contains a narrow fusiform swelling or
promontory starting from the centre, and corresponding to the rear swelling of the
dorsal compartment. These swellings are each, except the posterior, ornamented
by one or more scattered sharp little tubercles. Two slightly curved longitudinal
ridges divide the posterior compartment into three nearly equal petaloid areas,
which are transversely slightly concave. These ridges and the rim (at least in the
posterior dorsal region) bear a single regular row of similar sharp tubercles.
Size.—Left valve 9°2 mm. long by 7°4 mm. high.

CERATIOCARIS. 7
LTingula squamiformis beds of the Marwood series, is in the Woodwardian Museum,
and a fragmentary specimen from Pilton is in the Porter Collection.
Remarks.—This fossil has been very fully described and illustrated by my friends
Professor Rupert Jones and Dr. H. Woodward in the ‘ Geological Magazine,’ and
the reader is referred to that article for further information upon it.
Affinities.—Professor Rupert Jones describes it as larger and less ovate
than H. socialis, Beecher,’ and as differing from the other species described by
Whitfield, by Clarke, and by Hall, in having two (instead of one) tuberculate
ridges.
2. Genus—CerrRatiocaRis, Salter, 1849.
1. CERATIOCARIS ? SUB-QUADRATA, n. Sp. PI. 1, figs. 5, 5a.
Description.—Carapace-valve ovate-oblong, gently convex. Dorsal and ventral
margins gently arching. Anterior margin broad, truncated, with an ogee contour,
rounded at the extremities. Posterior margin broad, elliptical. Ventral margin
with a strong double rim, vanishing at its extremities. Surface, as seen from the
mould, with a few very minute threads or lines arching from the ventral margin
over the shell, with the antero-superior corner as a focus.
Size.—Length 19 mm., height 13 mm.
Locality.x—T wo or three specimens on one slab are in my collection from East
Anstey station.
Remarks.—These fossils are in poor preservation, and it is difficult to discern
their true nature. It is my strong impression that they are crustacean, and will
probably prove to belong either to Saccocaris or a kindred genus. The ornament
is not unlike that of a Lamellibranch, but several points seem decisive against
such an explanation, while somewhat similar markings are seen in Hstheria.
Though the ogee shape of the one end agrees with one end of Ceratiocaris,
the valve appears shorter and more truncate than usual; while the threads
on the surface take a different direction from the characteristic longitudinal
lineation of that group, with which for the present I have provisionally left it.
Affiinities.—In general outline it somewhat approaches C. stygia, Salter’;
while C. inornata, M‘Coy,*? though longer and more angular has several points of

resemblance. Saccocaris major, Salter,’ is more similar in its general shape, and
has signs of concentric lines though differently arranged.
Orthonotella Faberi, S. A. Miller,’ has a strikingly similar appearance, but is
much smaller and narrower, and has more numerous striz, and straighter and
more parallel upper and lower margins. This fossil Professor Rupert Jones noted
in 1883 as being probably a phyllocarid.
2. CeratTiocaris? sp. Pl. I, fig. 6 [cf. Pl. II, fig. 12].
Description.—Shape flatly convex, elongate, nearly regularly oval in outline.
Size.—Leneth 5 mm., height 2 mm.
Locality.—Two moulds, giving the two sides of one animal, from south-west
of Sloly, are in the Woodwardian Museum.
Remarks.—These fossils are exceedingly indistinct, beg a double mould so
divided that the edges are obscure. Almost the only marks I can observe
are a slight sharp notch or dent in the centre of one end, and slight indications
of a border on the lower margin, apparently becoming a broad, flat, angular rim
at one end. The test was perhaps rather thick. It appears to me that it is in
all probability the remains of a crustacean, and what can be seen of it is so
strikingly like Ceratiocaris ? simplex, Clarke,’ except in size, that it seems best to
treat it provisionally as probably akin to that fossil.
Note.—Two somewhat similar convex and elegantly oval casts, differimg from
each other in contour and size, have a neat rimon the free margins. One of these,
Pl. I, fig. 12, which is in Mr. Hamling’s Collection from Croyde has about the
same dimentions as PI. I, fig. 6, and its surface apparently has a few indistinct
microscopical longitudinal ridges.
It resembles Cytheropsis ? melonica, Barrande,* another very indistinct species,
which is somewhat undulated in its dorsal contour. The genus “‘ Cytheropsis”’ has
been abandoned.
The other specimen, which is in my Collection from Saunton Point, is about
ten times as large.

Description.—Form elongate, subcylindrical, flatly convex. Upper margin
bluntly elbowed at about one-fourth its length from the proximal end. Lower
margin straight, inclined at a small angle to the upper margin. Proximal end
concave, bounded by a narrow-margined rim. Distal end defective.
Size.-—Length 24 mm., breadth 7 mm.
Locality.—There is a single specimen from Sloly in the Porter Collection.
Remarks.—This fossil shows no definite structure, the markings generally being
too much hike those on the adjoining matrix to be relied on. Its shape is peculiar,
and may be described as resembling the breech portion of a gun. It sufficiently
resembles the fossil named <Anatifopsis acuta by Barrande’ to be regarded as
possibly congeneric, differing from it in being much more elongate, and not
showing the arching distal end seen in the Bohemian species, which Barrande
considered as akin to Lepas. ‘Two obscure spots, however, occur on the convex
surface of our specimen, one of which seems pectiniform. In Dr. Woodward’s
opinion this pectination may indicate the remains of gastric teeth, and therefore
imply that it is a Phyllocarid.
Affinities.—A. longa, Barrande,’ which approaches it in length, has a straight
upper margin.

Size.—The largest English specimen which I have seen (locality unknown),
exceeds five inches in length.
Localities.—The specimens are almost always either detached heads, bodies, or
pygidia. Inthe Museum of Practical Geology are four from Croyde, one from Hast
Hill, Braunton, three (including a head figured by Salter) from New Road Quarry,
Pilton, and one from Baggy Point. In the Barnstaple Athenzum are 2 from
Saunton, 3 from Pilton, 10 from Top Orchard, 1 from Bradiford, 1 from
Brushford, 5 from Kingdon’s, Shirwell, and 1 from Roborough. In the Porter
Collection are 4 from Pilton, 1 from Top Orchard, and 1 from Poleshill. In
the Woodwardian Museum are 16 from Top Orchard, 1 from west of Saunton
Court, 1 from south-west of Sloly, and 60 from Barnstaple. Inthe British Museum
are four from Marwood and Barnstaple.
Remarks.—As the specimens of this well-known Trilobite from these beds,
though so numerous, are all imperfect, and generally distorted, I have for the
present deferred attempting a detailed description of them, especially as the
species has already been fully described by Salter in his Memoir published by the
Paleontographical Society.
It appears to me that all the above-named specimens most probably belong to
the present species, though they vary very greatly in size, and have in some cases
ee
PHILLIPSIA. al
been referred to Phacops granulatus, or Trimerocephalus levis. Some of the
specimens in the Woodwardian Museum are at first sight very different, being
apparently shorter with narrower segments and a narrower axis, but my
impression is that these differences are entirely due to distortion. Hven the very
small heads appear to have the usual obtuse and perpendicular front margin
characteristic of this species, and not the subangular and protruding fronts seen
in T. granulatus from South Petherwyn.
Again, as a specimen in the Museum of Practical Geology labelled T. levis,
Minster, sp., from Brushford, which was probably the grounds for Salter’s
recording that species from these beds, appears to be exactly similar to our other
specimens, I am inclined to delete that species from the Pilton list.
The coarse granulation, absence of furrows, and great width and shortness of
the glabella, and especially its unprotruded perpendicular front, seem to be some
of the distinguishing marks of the species. The axis of the pygidium shows
tubercles in well-preserved specimens.
Affinities —P. Potieri, Bayle,’ seems to have a narrower, more protruding, and
more finely granulated glabella.
P. rana, Green,” has finer tubercles on the glabella and more segments in the
pygidium.

protruding front, and more segments in the pygidium.

rim in front. Basal lobes rather large, subtriangular. Glabella-furrows three
(including that which bounds the basal lobe), short, sufficiently clear except the
first. Neck-furrow deep. Neck-lobe arching, rather broad. Rim (in front of
glabella) rather broad, sigmoid in section. Fixed cheeks exceedingly narrow in
front, medianly convex at the eyes. Surface bearing numerous small scattered
tubercles. Free cheeks large, gently convex, subtriangular. Genal angles acute,
apparently prolonged into short spines. Hyes of medium size, elongate, bean-
shaped, rather elevated, situated centrally on the cheeks close to the glabella.
Thorax large, of nine rather broad segments. Axis wide, elevated, semi-
cylindrical, bounded by deep axial furrows. Segments divided by a distinct central
groove on the limbs.
Pygidium small, probably slightly broader than long, highly ornate, composed
of thirteen coalesced somites. Axis deeply convex, slightly flattened above,
nearly one-third the width of the pygidium at the proximal end, but diminishing
regularly and rapidly, and terminating bluntly at a quarter the length of the
pygidium from the posterior margin, followed by an indistinct prolongation.
Rings of axis thirteen (of which eleven are distinct), narrow, elevated, each
bearing a row of about ten strong sharp tubercles. Limb with eight grooved
pleurz, each of which consists of a narrow raised rib, irregularly tubercled,
extending to, and apparently becoming wider at, the border, and of a lower
and shorter intermediate rib, similarly ornamented, and placed immediately
behind the major rib in the furrow. Border convex, broad, rather distinctly
defined by a linear depression, one-fifth the length of the tail behind, and becoming
slightly narrower laterally, the tuberculated ribs being visible across it.
Size.—A specimen measures 18 mm. long by 8 mm. wide across the first, and
7 mm. wide across the last thoracic segment. A distorted glabella is 6 mm. long
by 3 mm. wide. A distorted pygidium is 7 mm. long by 11 mm. wide.
Localities.—-In the Barnstaple Athenzeum is a complete but very much decayed
specimen from the shore near Fremington, and two beautifully preserved pygidia
labelled Pilton and Braunton Road; and in the Porter Collection two pygidia and
a glabella from Pottington. All these specimens appear to have been collected
by Mr. Porter, and therefore probably all, except the first, may have come from one
locality.
Remarks.—The complete specimen, occurring in light brown sandstone and
much decayed, is crushed obliquely, which perhaps gives it the appearance of being
more elongate than that it actually is, but even so it appears to be distinguishable
by the large relative size of the thorax and by its elongate form. It serves the
purpose of showing that the more perfectly preserved specimens of detached
pygidia and glabella belong to one species.
The other specimens are in a much squeezed and twisted blue limestone ; and,
BRACHYMETOPUS. 13
though in a beautiful state of preservation, are so distorted that their exact shape
and relative dimensions cannot be ascertained. The pygidia assume, in fact, such
different appearances, according to their lie in the stone, as to suggest at first sight
that they are specifically distinct ; but Dr. Hicks, who has examined them, confirms
my opinion that they all undoubtedly belong to a single species.
Affinities—The present species evidently belongs to the genus Phillipsia, and
approximates Ph. truncatula, Phillips,’ sp., but differs distinctly in the shape of the
glabella, the number of glabella-furrows, the number of somites in the pygidium,
and in the presence of a distinct broad elevated convex border round both head
and tail.
Ph. gemmulifera, Phillips, sp.,’ differs in being broader, and in having a shorter
thorax and a smooth glabella, and narrower fixed cheeks.
It may be observed that the ribs of the pygidium seem more definitely distinct
and divided than is usual in Phillipsia or Griffithsides, thus approaching those
of Brachymetopus. From B. ouralica, de Verneuil,’ which it simulates in that
respect, it differs in its broader and more developed border, and in its rings being
only twelve or thirteen instead of seventeen, while its head is of course totally
unlike.
2. Genus—Bracuymerorus, M‘Coy, 1847.
This genus is distinguished from its neighbours by the small size and triangular
form of the glabella, Dechenella approaching it most nearly in these respects, but
differing as well in the greater size of the glabella and its more defined lobes as
in the strong striated margin of the pygidium. Several species have been described
by M‘Coy, H. Woodward, and others from the Carboniferous beds. The following
species carries back the genus to the Devonian; while, as Ghlert* points out,
Proétus micropygus, Corda,® represents it in the so-called Silurian Etages H and F
of Bohemia.

14 DEVONIAN FAUNA.
1. Bracnymetopus Woopwarpil, n.sp. PI. II, figs. 9—11.
Description.—Head-shield minute, semicircular, surrounded by a broad flat
border. Glabella very elevated, about two-thirds the length of the head, and about
twice as long as broad. Cheeks elevated. Eyes small, lunate, situated in the
centre of the cheeks. Surface tuberculate.
Pygidium very convex, semicircular. Axis nearly as wide as limb, very
elevated, bluntly truncated below, and with eleven or twelve lofty narrow rings,
which bear numerous tubercles, of which the central vertical row seems the largest.
Limb with seven elevated ribs on each side. Ribs simple, bearing a few coarse
tubercles, and extending to the border, which they appear to nodulate, a single
corresponding nodule being at the posterior point of the border.
Size.—Head-shield about 38°50 mm. long by 5 mm. wide.. A pygidium
measures 2 mm. long, 4 mm. wide, 1:25 mm. deep.
Localities. —Two specimens, a head-shield and a pygidium, are in the Porter
Collection from Pottington. A head-shield from the lane between Wrafton and
Heanton is in my collection.
Remarks.—We have in this case a head-shield and a pygidium of the identity
of which there is no direct evidence, but which occur in the same beds, are totally
unlike any accompanying species, and have such a general congruity that it
appears to be practically safe to assume that they belong to each other (specifically).
In this view Dr. H. Woodward agrees, and he confirms me in regarding it as a
species of Brachymetopus allied to B. MacCoyt, from which it differs in the larger
size of its glabella, and the fewer somites, greater shortness, broader axis, and
more highly ornamented character of its pygidium.
The specimen of the pygidium being in the nature of an internal cast, it is not
clear whether the final spines or tubercles of the lateral ribs extend beyond the
border, and so break the contour of the margin, but they certainly give indications
of doing so; and such a feature is hinted at by M‘Coy’ in his description of the
genus.
Orper—OSTRACODA, Latreille, 1801.
In the examination of the little fossils of this group I have had the advantage
of the guidance and assistance of my kind friend Professor Rupert Jones. They
have for the most part been the result of very recent discoveries, and probably by

no means cover the whole ostracodal fauna of the beds. Time did not permit
their full study before they were put on the plate, and consequently they were then
arranged according to their apparent general similarity. A more minute examina-
tion proved that in some cases these resemblances were deceptive, and were due
simply to the crushing or corrosion of specimens having really different characters.
While this has caused some of the figures to be useless as far as the elucidation of
their own species is concerned, it is perhaps not uninteresting as showing how
easily one genus may apparently be transformed into another by a slight modifi-
cation of its characters.

Description.—Valve suboblong, generally rather short, moderately convex,
with a central spot or muscle-mark. Dorsal margin rather shorter than the
valve. Free margins bounded by a definite rim.
Size.—Length 2 mm.
Localities.—In the Porter Collection is a slab with several specimens, from
Poles Hill; and in my collection two specimens from Upcott Arch Quarry, and
one from Saunton Hotel.
Remarks.—These specimens all appear to be casts; they seem always to show
the central spot or dent.
Professor Rupert Jones has identified the more perfect specimens with
Krause’s species. He considers they come very near to Primitia valida,’ but
are distinguished by the ventrally protruding convexity of the valves, and by
the outstanding lips or borders.
From P. centralis, Ulrich,’ they seem to differ chiefly by being more convex.
Primitia cestrensis, var. caldwallensis, Ulrich, and P. subequata, Ulrich,‘ are
also so similar as hardly to be distinguishable except in the same particulars.

Description.— Valve short, ovate, convex. Anterior end subtruncate, rather
narrower than the other, which is rounded. Dorsal edge rather short. Ventral
margin strongly arched. Surface bearing a small, low tubercle close to the antero-
dorsal corner.
Size.-—Length 2 mm., height 1°5 mm.
Locality.—A specimen from Kingdon’s, Shirwell,is in the Barnstaple Atheneum.
Remarks.—The figured specimen is embedded in hard limestone, and possibly
does not show the true margin all round. Professor Rupert Jones considers it to
approach very near to A. ovatus, Jones and Holl, sp.’ It differs, however, from it
in being shorter and more evenly convex. A. simplex, Jones,” agrees better in
these points, but seems more regularly oblong. A. Lindstremi, Jones,’ is almost
identical in outline, but is so much smaller and flatter as probably to indicate
that our specimen belongs rather to a larger variety than to the described type.
8. Genus.—Primitia, Jones and Holl, 1865.
1. Primitia sparsinoposa, n. sp. PI. III, figs. 4—6.
Description.—Valve elongate, oval, convex. Dorsal and ventral borders
almost straight. End borders rounded. Valve divided by a deep, broad
dorsal furrow, sloping down from the centre forward, and separating it into
two flatly swollen convexities, each of which bears a tubercle (not distinctly
shown in the figure) near the centre of its lateral face, while another small
tubercle is on the angle of the anterior lobe, overhanging the furrow.
Size.—Length °83 mm.
Locality.—Three specimens are on the slab in Miss Partridge’s collection from
Saunton Hotel.

PRIMITIA. 17
Remarks.—These specimens are casts, but show the shape rather clearly ; they
evidently had rather thick tests.
Professor Rupert Jones was inclined to identify these specimens with his
Primitia mundula, var. longa.’ Our specimens, however, on close examination
show several distinct scattered tubercles, which do not seem to exist in
P. mundula; and, moreover, the sulcus sets forward instead of being nearly
vertical, and the shape is more oval.
Bollia ? sinuata, Krause,? seems more oval, and the central furrow is more
direct, and ends in a circular pit.
Primitia impressa, Ulrich,’ is relatively shorter and more oval.
Ulrichia confluens, Ulrich,* is somewhat similarly nodulated, but its furrow is
much wider and more L-shaped.
The small specimen, fig. 4, appears probably to be a young or indistinetly
preserved example of the same form.
2. Primitia, sp. Plate III, figs. 7—11.
Description.—Valve elongate, ovate-oblong. Dorsal and ventral edges nearly
straight. Ends nearly evenly convex. Surface finely tuberculate, marked with a
slight central inequality in the dorsal region.
Size.-—Length 1 mm.
Localityx—T wo specimens from Pilton are in the Porter Collection ; two from
Saunton Hotel in Miss Partridge’s Collection; and several, which are very
doubtful, from Saunton Hotel in my Collection.
Remarks.—These fossils show very little character; there are indications of a
central vertical inequality in the valve, which is probably Primitian in character,
but has been more or less modified by pressure. The four first-mentioned specimens
appear to have been covered with avery fine granulation. In those from Saunton
the great squeezing of the beds has very much obscured the natural shape, as will
be seen from my two specimens figured from that locality.

Description.—Valve very small, evenly convex, short, subovate. Dorsal border
straight, rather short. Anterior border narrow, bluntly subangular. Posterior
border semicircular, broad. Ventral border convex.
Size—Length *5 mm.
Locality—One indistinct specimen is in a slab with other Ostracods in
Miss Partridge’s Collection from Saunton Hotel.
Remarks.—This indistinct little fossil seems in general shape extremely like
Leperditia ? seneca, Hall, as given by Jones,’ but it appears to show a slight sulcus
in the dorsal centre followed by a slight posterior elevation, and therefore is
probably a species of Primitia.

broken by a vertical projection behind a short sulcus. Free borders convex.
Size.—Length *5 mm.
Locality.x—One small specimen from Saunton Hotel is in Miss Partridge’s
Collection. | .
Remarks.—This specimen Professor Rupert Jones considers sufficiently near
to P. dorsicornis to be referred to it. It has some alliance to the accompanying
P. sparsinoda (fig. 7), but that appears distinguished by the absence of a pro-
jecting node.
It appears to be a passage-form into the genus Afchmina, approaching
Ai. Byrnesi, Miller,’ but with a smaller and more vertical spine.

5. PrimiviA BovIFRONS, n. sp. Plate III, figs. 25—30.
Description.—Valve suboblong, elongate, flattish. Dorsal margin straight and
equal to the length of the carapace. Ventral margin almost straight, oblique.
Ends unequally rounded. Anterior portion rather narrower than the posterior.
Valves with a broad, shallow central furrow, edged with two slght prominences,
extending perpendicularly from the dorsal margin halfway down, and having a
sharp elevated tubercle or horn standing out from the valve rather below the antero-
superior corner, and in the extreme postero-dorsal angle another horn which is
very lofty and tends upwards and backwards. Free margins bordered by astrong
impressed rim (fig. 28). Surface covered by a coarse, irregularly honeycomb reticu-
lation, with concave interspaces.
Size.—A large specimen is 4°2 mm. long, and 2°3 mm. high.
Localities.—In the Porter Collection is a slab containing four or five specimens
from Pilton; and in my Collection are several specimens from the Pecten newilis
bed of the Laticosta Cave, Baggy, one of which (fig. 27) has been squeezed into a
symmetrical shape.
Remarks.—This fossil is referred to the genus Primitia by my friend
Professor Rupert Jones on account of its furrow, but he recognises that its central
tubercles, which in some specimens are strongly developed, show a passage
toward Ulrichia.
It was first known to me by Mr. Porter’s specimen, the locality of which was
indefinite, but I have since found it in plenty at Baggy Point together with other
Ostracods.

Description.—Valve elongate, subovate or bean-shaped, rather flat. Dorsal
border straight, nearly as long as the valve. End borders narrow, very
convex, angular above and passing insensibly below into the long convex ventral
border. Valve with a central oval node defined above and at the sides by an
impressed furrow, and with very indistinct and diffused lateral lobes. Ornament
of coarse elongated rugosities (not clearly shown in the figure) radiating from the
central node. Rim indistinct, oblique or bevelled.
20 DEVONIAN FAUNA.
Size.—Length 2:2 mm.; height 1°3 mm.
Locality.—There is one specimen in the Porter Collection from Pilton,
associated with a value of Strophalosia productoides.
Remarks.—This species bears great resemblance in shape, ornament, and
markings to Beyrichia clathrata, Jones,’ though differimg somewhat in each
particular. It appears to stand about halfway * between that species and Leperditia
mundula, Ulrich,’ being nearer to the former in general contour and ornament and
to the latter in outline. It is possibly the same as the latter, though it slightly
differs from it in the size and shape of the furrow. In any case, however, as it
evidently is a Primitia, and has no connection with P. mundula, Jones, we are
obliged to retain our proposed name.

Localities.—Several specimens are in my Collection from Saunton Hotel.
Remarks.—The specimens are all very much squeezed out of shape; and,
probably, the one figured has been shortened from that cause. On the whole,
however, they seem to be distinguished by three elongate equal lobes.
Affinities.—It appears so closely to resemble B. xquilatera, Hall, as given
by Jones, that I am inclined to think it identical.
1 1857, Jones, ‘Ann. Mag. Nat. Hist.,’ ser. 3, vol. i, p. 242, pl. ix, fig. 1.
* Dr. Holzapfel translates this phrase, which I used in vol. i, p. 10, in reference to a Trilobite, by
the word “ Mittelform,’ and then proceeds at great length to prove me incorrect in so callingit. The
simple answer is that I never called it a “ Mittelform”’ at all. In stating that in appearance it stood
midway between two other species I in no way implied, or intended to imply, that it was a passage-
form between them.

BEYRICHIA. 21
In B. oculina, Hall,' the central lobe seems separated below, and the lateral
lobes coalesce beneath it.
Professor Rupert Jones has suggested a comparison of it with the specimen
of B. Kledeni, M‘Coy, figured by him in 1881.’ It does not seem to me that the
rather numerous though always distorted specimens I have seen show signs of
conformability to that species. Their lobes are always long, straight, and evenly
joined below.
B. Steusloffii, Krause,> seems to differ in the same manner.
B. Wilckensiana, Jones, as given by Krause,* seems to have thicker lobes, and
a more elaborated anterior end.

Description.—Valve small, elongate, suboval. Ventral margin nearly straight.
Ends obliquely convex. Valve having three subequal tubercles between two broad
shallow furrows; the central tubercle being the most nodular, and the lateral
tubercles indistinctly united below.
Size.—Length °6 mm.
Locality.—One specimen from Pilton is in the Porter Collection.
Remarks.—This specimen is indistinct, but as far as can be seen it presents
almost exactly the appearance of B. Damesii, and therefore I venture to refer it
provisionally to this species.
Affinities. —To B. concinna, Jones and Holl,’ it is very similar, but the lobes
appear to be thicker in that species. Several of the varieties ° of B. Kledeni,
M‘Coy,’ are sufficiently like it to suggest that it possibly may prove nothing beyond
a variety of that highly unstable species.

1. Bryricutopsits Rorerti, n. sp. Plate III, fig. 17.
Description.—Valve rather long, suboblong, flattish. Dorsal margin straight,
equal to about two-thirds of the length. Ventral margin nearly straight,
horizontal. Ends semicircular. Valve with (1) a small anterior lobe close to
the dorsal edge and defined behind by an oblique sulcus; (2) a small indistinct
ventrally situated convexity, and (3) a large diffuse posterior lobe bearing in the
dorsal corner a small tubercle; and (4) several longitudinal ridges on different
parts of the surface. Border bearing a narrow fringe.
Size.-—Length ‘8 mm. ~
Locality.—There is one specimen from Pilton in the Porter Collection.
Remarks.—It appears to me that this small fossil answers all the requirements
of the genus Beyrichiopsis, though it was only after the drawing had been made
that further examination brought out its true characters, and therefore they are
not well seen in the figure.
Affinities —The smaller size and different position of the lobes distinguish it
from B. fimbriata, Jones and Kirkby,’ and B. fortis, J. and K.,’ and B. subdentata,*

as long as the valve. Postero-superior corner angular. Free edges gently
convex and bordered with a narrow rim. Anterior portion of the valve narrow.

third coalesce below, while the central lobe seems sometimes more defined.
Posterior lobe sometimes bifid.
Size.-—Length 1:5 mm.
Locality.— Numerous specimens from the Ostracod Bed, Laticosta Cave, Baggy
(where it seems to occur frequently) are in my Collection.
Remarks.—This species seems variable, but the variation is partly to be
accounted for by the immense squeezing ‘and twisting which the beds have under-
gone, as seen hy the shapes assumed by larger fossils... Hence it is hard to arrive
at the true form of the species. The specimens numbered 22 and 23 are examples
of shortened aspects it assumes under distortion, and at first sight appear to belong
to different genera, but on examination prove to be the present species. On the
other hand elongate valves with faint ridges, represented by figs. 19 and 20, occur
frequently ; it seemed at first that these must be distinct, but on tracing out the
differences seen in numerous specimens it becomes evident that they are simply due
to fossilisation, and that they cannot be separated from the rest even as a variety.
Ajjinities.—Kledenia notata, sp., Hall,’ seems not unlike, and possibly under
varying pressures would present similar forms.
7. Genus—Utrionta, Jones, 1890.
1. ULRIcHia INTERSERTA, n. sp. Plate III, fig. 24.
Description.—Valve long, semi-oval. Dorsal border straight, almost as long
as the valve. Ventral border elliptic. Ends rather strongly and evenly rounded ;
with thickened margins rising up from the ventral border. Surface bearing two
large, prominent, obliquely oval, median well-defined lobes, not united below,
Size.—Length ‘8 mm.
Localities.—T here is one specimen in my Collection from the Ostracod bed at
Baggy.
Remarks.—This fossil is regarded by Rupert Jones asan Ulrichia. It appears,
however, to mark a passage from that genus to Bollia; for, while the lobes are
distinctly defined below, there is a decided thickening of the lower portion of the
valve. This passage between the two genera is continued by Bolla bilobata, Jones,”
which has equally large lobes, united by a low swelling. ‘The latter is also distin-
guished by being more oblong. i

Sub-genus—Aconiatites, Meeh, 1877.
1. AconraTITEs, sp. Plate IV, fig. 2.
Description.—Shell of moderate size, discoid, flattish. Umbilicus rather small,
shallow, open. Whorls rising steeply from the umbilicus, turning immediately
through nearly a right angle to form a sub-angular elbow, and then spreading out
flatly towards the back, and bearing on the elbow (or margin of umbilicus) a few
slight undefined radiating nodules. Suture arching backwards from the elbow or
umbilical margin in a simple lateral saddle for more than half the width of the
whorl.
Size.—Diameter about 30 mm.
Locality.—A single imperfect specimen from Kingdon’s, Shirwell, is in the
Barnstaple Athenzum.
Remarks.—Though a portion only of this shell is visible in the matrix,
Mr. Crick points out to me that it evidently, from what is seen of its suture-line,
belongs to the group or genus Agoniatites, and is closely allied to Agoniatites
transitorius, Phillips, sp. ‘There are also slight signs of transverse lineations as in
that species, but it differs from it by having nodules or swellings on the margins
of the whorls just round the umbilicus.
Affinities —G. Roemeri, Holzapfel,’ has a smaller umbilicus, more sloping
sides, and no nodulations.

SUBCLYMENIA. 25
2. GoniatiTEs, sp. Plate IV, figs. 1, la.
Description.—Shell very small, globose. Umbilicus minute, deep. Sides of the
whorls rising from the margin of umbilicus for a short distance in a gentle curve,
and then arching round still more gently to form a broad, regular, and very mode-
rately convex back. Suture-lines unseen. Sulci three (two only being distinctly
visible) straight, crossing the whorls perpendicularly.
Size.—Diameters 10 mm. and 9 mm.; width 6 mm.
Locality.—Two small specimens from Barnstaple are in the Woodwardian
Museum.
femarks.—These specimens, which from the nature of their matrix evidently
come from the Pilton beds, show little beyond the general form of the species, the
chief feature of which is the convexity of the sides as they rise from the umbilicus.
The shell is very closely coiled, the backs of succeeding whorls having little
room between them, so that the shape of the shell-cavity must have been highly
lunate, and the whorls numerous.
Affinities—Goniatites micromphalus, F. A. Rémer,' of the Wissenbach slates,
differs in having the margin of the umbilicus higher and more angular.
Mr. Crick and I compared the specimens with Carboniferous examples of
G. crenistria (the name these specimens had borne in the Museum), and came to
the conclusion that it was in no way connected with that shell. With G. linearis,
Miinster, as given by Phillips, it may have more in common, but I am not certain
whether the rounding-in of the shell round the umbilicus occurs in that species.

“This genus differs from Discitoceras (Discites) in the sutures and position of
the siphon. The sutures have a deep V-shaped ventral and acute linguiform first
pair of saddles, first pair of lateral lobes narrow, a second pair of small lateral saddles
near the umbilical shoulders, and dorsal saddles divided by shallow annular lobes
with a minute median saddle. The abdomens are hollow, and the dorsal region
gibbous, as in the adults of Aphelxceras. The siphon is near the venter, but the

funnels do not approach near enough to interrupt the sutures or affect the depth
of the ventral lobes. But one Carboniferous species is known—S. evoluta, Phil.’*
De Koninck proves this genus to belong to the Nautilidz.
1. Sosctymenta Symonpstr, MS. Plate VII, figs. 3, 3a, 4.
Description.—Shell very large, discoid, flattish, of two or three volutions,
which appear probably to have been free, and to leave a central vacuity. Whorls
rapidly increasing, sub-quadrate, nodose; ventrally broad, concave; dorsally
narrow, slightly concave. Sides convex, rising slowly from their dorsal side to
the shoulder for about two-thirds their height, and then curving down to the
ventral side, where they seem bounded by a sharp angle ; barred by distant ridges
which swell into large lofty bluntly conical nodes, at the shoulder, about twelve
nodes to a whorl. Body-chamber probably large. Suture-line with a very long
v-shaped central saddle, rather deep and convex central lobes, and low lateral
saddles. Ornament consisting of small, crowded, unequal, rounded transverse
riblets, divided by narrower grooves, running slightly backward from the inner
margin to the shoulder, where they vanish; crossed by comparatively few distant
impressed threads, which are absent on the shoulder but reappear on the ventral
part of the side. Shell-structure probably not massive.
Size of cast.—Diameters 165 mm. and 110 mm. Width 65 mm.
Localityw—In the Museum of Practical Geology are two specimens from
Luscott, near Braunton, one of which is a very large cast retaining in one place
signs of the surface-markings, and the other the mould or inner surface of a
smaller shell.
Remarks.—The largest specimen in the Museum is a splendid fossil, but in
many respects it is most difficult to interpret. In the first place it has evidently
been subjected to very great slant pressure, which has compressed it, altered
the character of its coiling, and obscured the true shape of its whorls. Again, its
whorls are so widely separated that it is difficult to imagine that they were in
contact unless the shell-structure were immensely thick, which the fact of the
cast bearing traces of the surface-ornament renders very improbable. Moreover,
1 1884, Hyatt, ‘Proc. Boston Soc. N. H.,’ vol. xxii, p. 293.

POTERIOCERAS. 27
the stone is so covered with cracks and inequalities that anything in the nature
of sutures is most difficult to trace. Lastly, several of the nodes on one side are
removed by clean-cut concavities in such a way as almost to suggest that it had
agglutinated foreign substances after the manner of Philoxene.
The species has been quoted in catalogues under the name of Porcellia
Symondsui in accordance with the old label which the fossil bore in the Museum.
Repeated examinations, however, convinced me that it was impossible that it
could belong to that genus. Being struck with its great likeness to a Cephalopod,
I then consulted Mr. Crick upon the subject, and his practised eye succeeded in
tracing several of the suture-lines, and thus settling not only its order but its
genus. ‘This at once elucidated several of the perplexities about the fossil. It
became evident that its elliptic shape was wholly due to pressure, and also that
the same cause had probably exaggerated the originally broad, gently concave
ventral surface into a narrow and deeply concave groove. Further, on our
examining the specimen figured by Phillips'as Nautilus tetragonus (= Discites
Omalianus, de Koninck,’ sp., according to Foord*), which Hyatt refers to
Subclymenia, it was seen that the surface-ornament, though not identical, was
of such a kindred nature as to confirm Mr. Crick’s conclusion.
Affinities.—Our species is at once distinguished from the type species of the
genus, S. evoluta, Phillips, sp.,* with which de Koninck ° afterwards identified his
Nautilus Omalianus, by the presence of nodes.

Description.—Shell apparently short, very rapidly tapering, recurved. Section
quadrately sub-ovate, wider than deep. Siphuncle small, circular, 1 mm. in
diameter, sub-central, being rather near to the convex side. Body-chamber
expanding. Septate part apparently rapidly expanding, consisting of very narrow
chambers, 3 mm. in height, with rather shallow concave septa, rather oblique,
sloping slightly down (?) toward the convex side. Test thin.

Locality.—A specimen from Kingdon’s, Shirwell, is in the Barnstaple Athenzoum.
Remarks.—This is evidently a species of either Poterioceras or possibly
Gomphoceras. Its more central siphuncle (which is situated at a point 10:16 on
the transverse diameter) distinguishes it from the various species found in South
Devon; but the only specimen of it is unfortunately far too imperfect for
identification.

Locality.—Phillips’s figured specimen from Marwood is in the Museum of

Remarks.—This specimen is as poor as well could be,—consisting of eight
crushed chambers from which the external parts are gone. It affords us little
knowledge of the shell, except that it shows that there is a distinct wide shallow
sinus or bay in the front margins of the septa, which I had not observed in the
South Devon specimens, and hence that one point of difference in Phillips’ shell
from Actinoceras Sowerbyi, M‘Coy,is removed, though on the other hand the
almost exactly central position of the siphuncle is confirmed.
From the apparent rapidity of tapering in the above specimen, it seems to me
most probable that it will, after all, prove to be distinct from the South Devon
O. Champernowni, and to belong to Poterioceras or Gomphoceras.

ORTHOCERAS. 29
Description.—Shell very large, decreasing slowly at the rate of 1:12. Section
oval, in ratio, 8:7, Chambers narrow, being in height about one seventh or
one eighth the width of the shell. Septa sloping very obliquely across the
short diameter. Siphuncle sub-circular, about one half an inch in diameter, 3ub-
central, consisting of long vasiform or ellipsoidal beads, suddenly constricted into
narrow concave necks at the septa, their greatest and least widths being as 7: 5.
Test about 3 mm. thick (in largest specimen), showing no markings.
Size—A large specimen is five inches by three and a half inches in transverse
diameters, but is probably slightly compressed.
Locality.x—A large specimen from Top Orchard Quarry is in the Barnstaple
Athenzum, and another, slightly smaller, from ‘‘ North Devon” in the British
Museum. The original of Phillips’s figured specimen (fig. 206 b) from the Pilton
Beds is in the Museum of Practical Geology.
Remarks.—These specimens are fragmentary and insufficient to identify the
species, which evidently was very large, probably several feet in length. Whether
the other specimen figured by Phillips (fig. 206 a) is identical I am not quite sure,
as, according to its figure, its tapering is more rapid, viz. 1 in 5 or 6 instead of
1 in 12; but it is possible that this apparent difference may be due to accidental
circumstances.
Neither is it at present clear that these Devonian fossils have any right to the
name of Sowerby’s Silurian O. Ludense.
Until more is known about its specific characters, it appears safer not to
attempt to identity it with species belonging to a different formation.
It appears from the character of its siphuncle properly to belong to the genus
Orthoceras, and is therefore probably distinct from the Lummaton species
described by me as Actinoceras devonicans,’ and from A. striatum, with which
M‘Coy ’ and Foord * had doubtfully identified it.
Affinties.—Orthoceras Pelops, Hall,* appears to equal it in size, and to be
similar in many characters, but we have not sufficient data for full comparison.

30 DEVONIAN FAUNA.
Localities—In the Barnstaple Athenzeum are four specimens from Kingdon’s,
Shirwell, a doubtful specimen from Top Orchard, and two more without localities ;
in the Museum of Practical Geology are two poor specimens from Marwood, one
from Baggy, and one from West Angle Bay, Pembrokeshire; in the British
Museum is one from Kingdon’s, Shirwell; and in the Woodwardian three from
Barnstaple.
Remarks.—It appears to me that the Shirwell specimens undoubtedly belong
to this species. Their surface is smooth ; their section slightly oval (10:8); the
siphuncle central and rather large; the ratio of the height of the chambers to
their width 2:5 or 2:6; the rate of tapering about 1 in 8. The specimen from
that locality in the British Museum is a body-chamber which is 110 mm. long and
36 mm. wide, and appears sub-cylindrical with a rate of tapering of only 1 in 12.
In the specimen from West Angle the shell-structure is rather thick, and the
surface though smooth to the naked eye is seen under a strong lens to be covered
with multitudinous microscopic impressed lines of which a few are slightly stronger
than the rest; a faint carina is seen on its cast similar to that figured on a specimen
from Lummaton.’
F. A. Rémer’s’ version of Orthoceratites regularis, Schlotheim,* seems to be very
similar to this species, but that form has much loftier chambers.
O. lineare, Minster, appears to differ in having fine elevated transverse threads
instead of simple lineations which do not alter the level of the surface.
3. OrrHocrRAS BarumENszE, n. sp. Plate IV, figs. 7, 7a, 8, 8a, 8b.
Description.—Shell generally small, vertically straight, elongate, conical,
probably tapering at about the rate of 1 in 10, covered by elevated, broad, slightly
oblique, arching, convex, undefined rings at the rate (in the wider part) of four
rings in a height equal to their width, which are separated by shallow concave
constrictions about twice as wide as the rings. Septa gently convex, slightly
oblique. Section circular or sub-circular with diameters as 9:10. Siphuncle
rather large, very nearly central. Chambers broad, being apparently about one
half their width in height in the smaller part (and probably decreasing to one
quarter their width in height when nearer the body chamber). Surface of the shell
entirely covered by minute, sharp, crowded, regular, distant, elevated, transverse
threads or striz, which sometimes slightly undulate, and are at the rate of nine
striz to 1 mm.

ORTHOCERAS. 31
Size—One specimen about 3 mm. in width is 20 mm. long. The largest
fragment I have seen is about 11 mm. wide.
Localities.—In the Barnstaple Athenzum is a small specimen from Brushford ;
in my Collection one from Ironpost near Dulverton, one from Frankmarsh, and one
from Upcott Arch Quarry ; in Miss Partridge’s Collection one from Lower Orchard
Quarry.
Remarks.—At first it seemed that two species were represented by these
fossils, the elevated annuli not being noticeable in the smaller specimens. After
a careful comparison, however, it appears that they are all identical. The annuli
probably became more prominent with the growth of the shell. They were
probably conterminous with the chambers, as in one instance they appear to
have been so, and if this is the case the height of the chambers varied from one
half to one quarter the width of the shell. The ornamentation though minute
is very definite, consisting of sharp striations considerably more than their own
diameter apart and sometimes occurring in bands of three or four of greater
fineness than usual.
Affimties.— From O. lineare, Miinster,' which is similarly lineated, this
species is distinguished by the possession of annuli. From O. ibex, Sowerby,’
and O. articulatum, Sowerby,’ it differs in the absence of longitudinal strie. The
same character seems to distinguish it from all the American Devonian forms.
O. ulbense, Tschernyschew,* agrees in form and rate of tapering ; but probably
differs in having fewer minor striz, and wider and more horizontal chambers, and
in being larger.
O. vertebratum, Sandberger,’ appears to differ in the striz being intermittent,
and perhaps in the annuli being larger.

32 DEVONIAN FAUNA.
Size—30 mm. long; 5 mm. wide.
Locality.—One specimen from the Marwood Beds of Baggy Point is in the
Barnstaple Museum.
Remarks.—The only specimen known to me from the Pilton beds is too poor and
doubtful to be worth figuring. Its septa are very unequal, and are often more than
half the diameter of the shell in height; though on the whole they seem rather
narrower than is usual in Sowerby and Phillips’s figures. Phillips compares it with
O. regulare, Minster,’ to which it is rather similar in some respects.
It is recorded by Phillips from the Carboniferous localities of Venn and
Swimbridge, as well as doubtfully from Baggy Point.
Afinities.— From O. specioswm it differs by its very much broader and more
unequal chambers.
5. OrtHoceras, sp. Plate IV, fig. 6.
Description.—Shell, small, straight, tapering at the rate of 1 in 7. Septa
shghtly oblique. Chambers about one quarter the width of the shell in height.
Siphuncle (or endosiphon?) beaded, being constricted just below the septa into
narrow necks about half its width, and then swelling out into convex-
shouldered, straight-sided beads which are rather wider above than below,
have rather stout walls and a microscopically rugose surface, and are clothed
with a subsidiary envelope (or exterior siphuncle?). Subsidiary envelope dumb-
bell-shaped, being very wide above and suddenly narrowing at about one-quarter
its length below the septa, its sides then becoming straight and then sometimes (?)
slightly expanding just above the next septum.
Size.—A defective specimen is 30 mm. high by 8 mm. wide.
Locality—A single specimen from Kingdon’s, Shirwell, is in the Barnstaple
Athenzum.
Remarks.—This specimen only showing the section of the shell, it is almost
impossible to identify it specifically. It seems, however, to be distinguished from
accompanying species by the different height of its chambers, so that it probably
represents a distinct species.
It seems remarkable for the arrangement of its siphuncular apparatus, which
in superficial shape exactly resembles that of Huronia. It is seen, however, that
the external envelope is entirely filled with white calcareous spar, and instead of a
linear endosiphon with expanding tubuli it contains a simple and entire beaded
tube. This tube Mr. Crick, who has very carefully examined the specimen with
me, regards as the true siphuncle. This being so, the exterior envelope, though
1 1840, Minster, ‘ Beitr.,’ pt. 3, p. 95, pl. xvii, fig. 4.
ACTINOCERAS. 33
evidently bounded by true walls, must be regarded as an organic deposition after
the manner of those figured in some species of Orthoceras by Barrande.
Hence it appears that whatever the species may be, it probably belongs to the
genus Orthoceras.
2. Genus—Actinoceras, Bronn, 1837.
1. Aotinoceras? (Huronia) Crick, n. sp. Plate IV, figs. 9? 10—i2.
Description.—Shell rather large, straight, tapering rather rapidly at the rate
of about 1:6. Section elliptic, having the siphuncle situated excentrically, rather
in front of the centre along the longer diameter, and considerably distant from
the centre along the shorter diameter. Chambers narrow, very slightly oblique,
and about one-sixth of the width of the shell in height. Septa shallow, convex,
somewhat steeper in front, and having a wide, very shallow bay or sinus on the side
farthest from the siphuncle. Siphuncle very large, about two-fifths the width of the
shell; consisting of a series of subturbinate or vasiform rosettes, rather wider than
high, which sometimes appear thickened by organic (?) deposits ; and containing in
its centre a slight free subcylindrical endosiphon. Endosiphon suddenly expanding
just below the top of each rosette into about four radiating horizontal tubuli,
which branch into minor tubuli near their extremities, are supported by ridges
below, and are more or less joined to each other by their lateral expansions.
Septa meeting the siphuncle only a little below its widest part, and enfolding its
lower portion .[? Surface (on the cast) showing a long longitudinal carina and signs
of rather distant alternating threads or stria, fig. 9.]
Size.—A specimen of twenty chambers is 80 mm. long by 25 mm. wide;
another, of about eleven chambers, is 55 mm. long by 27 mm. wide.
Localities.—Of external casts, probably belonging to this species, are two
specimens from Top Orchard, three from Pilton Vicarage Well, and one from
Fremington in the Barnstaple Atheneum; one from Baggy in the Museum of
Practical Geology; two from Pilton in the Porter Collection; and two from
Barnstaple and one from the south-west of Sloly in the Woodwardian Museum.
Of natural sections showing the siphuncle there is one “from Yeotomes’”’ in the
the Barnstaple Atheneum; one from Croyde and one from Barnstaple in the
Woodwardian Museum; and one from the Marwood Beds in the British Museum.
Remarks.—Most of the exterior specimens are very poor, and some are very
doubtful, and could hardly be identified specifically by themselves; but from the
dimensions of their chambers and other points they appear most probably to

belong to the same species as the remarkable natural sections last enumerated.
Signs of the ornament are only seen in a single specimen from Baggy, but they
appear sufficient to show its distinctness from the South Devon O. laterale,
Phillips.
The internal arrangements seem peculiarly perplexing ; while they approximate
those of Actinoceras, they appear to present several characteristics strongly indicative
of the Lower Silurian genus Huronia as differing from Actinoceras itself, e.g. (1) |
in the vasiform shape of the rosettes; (2) in having the tubuli not in the centre
but at the summit of the rosettes; (3) in the rosettes not being interseptal, but
sunk into the bases of the septa; (4) in the sides of the siphuncle being probably
unsymmetrical, one side appearing as though it were more evenly nummuloid than
the other; (5) in the siphuncle possibly not occupying a symmetrical position in
the shell. On the other hand, in the present species the septa and shell are
generally preserved, having only perished in one specimen, whereas in Huroma
they are hardly ever preserved.
Mr. Crick has most kindly taken much trouble in comparing these sections
with Cephalopods in the British Museum, and we together came to the conclu-
sion that they were so exceedingly like Ormoceras vertebratum, Hall,' = Ormoceras
Bayfieldi, Stokes,’ as in all probability to be congeneric. Hence the question arises,
as O. vertebratum is the type of the genus Ormoceras, whether that genus ought to be
united to Actinoceras after Foord or to Hwronia. Mr. Crick regards Stokes’s
type (which is in the British Museum) as very enigmatical, but its structure
seems to correspond with, and to be explained by, our specimens ; and it would
seem, if we read the present species correctly, that Ormoceras is only Huronia in
a different state of preservation, and that therefore Huronia has as much right as
Ormoceras to be classed as a synonym, or perhaps a group, of Actinoceras.
The fact that in Huronia the siphuncle is almost always the only part
preserved, which is said to prove the extreme tenuity of the shell, does not seem
a bar against this, for it is easy to imagine that some species of the genus might
have had thinner shells than others, or that shells in a siliceous deposit might
have more easily perished than a limestone. Moreover in one of our own
sections the siphuncle is the only part preserved, and in the other three the shells
are retained in a very imperfect and indistinct condition. It may be noted that
Stokes has, on the same plate as his Ormoceras, figured two sections of Huronia,
which seem extremely like our fossils.
At the same time there can be no doubt that the general affinities of this
species to Actinoceras are very great, and if the relationships to Huronia above
noted be verified by future specimens they will probably be found to be evidence

CONULARIA. 35
not that Huwronia, as distinct from Actinoceras, existed in the Devonian, but that
Huronia itself is merely a condition or, at most, a group of the genus Actinoceras.
Taking these sections in connection with the probable indications of external
ornament, there seem to be sufficient characters known to warrant the suggestion
of a name for the species.
Affinities. —The large Orthoceras Ludense, Phillips (not Sowerby), from
these beds seems distinguished by its much greater size, wider chambers, and the
shape of its siphuncle.
Actinoceras striatum, Sowerby* ( = O. lineale, de Koninck’), differs in having
much finer and more numerous equal lineations. It may be noted, however, that
in the Woodwardian Museum there are specimens from Mudstone Bay and from
Mawegan, which seem, in the few points visible, exactly like our fossils, and which
are there labelled Orthoceras striatum (probably on the authority of Prof. M‘Coy).
A. subconicum, @Orbigny,* is, as figured originally by Sowerby,* remarkably
like our sections, but has narrower chambers and more central tubuli.

about # mm. apart, elevated, coarse, sloping upward, and curving in the centre
so as sometimes to alternate and interlock at an angle of about 160°, or
sometimes to meet in a continuous curve; alternating and interlocking at the
margins. Interstrial spaces about four times the width of the striz, transversely
but irregularly lineated inside, and showing signs of coarse crenulation within
immediately under the striz, and very fine oblique lines on the outer surface.
Locality.—One specimen from Pilton is in the Porter Collection.
Remarks.—While this fossil gives abundant evidence that it belongs to the
genus Conularia, it is insufficient for very definite determination. It is flattened
and too fragmentary to show its exact shape, and the inner surface is the only
part well displayed. At the same time several characters are more or less clearly
indicated. Besides the points which are at first sight apparent, there may be
observed signs of a deep angular grooving at the corners, and in one portion,
where the cast of the outside surface seems exposed, a very fine and oblique
lineation is visible, which may, however, be partly due to accident. - The strize are
not perfectly regular, seventeen on one side of a face corresponding to twenty on
the other.
In the points observable it appears so closely to resemble C. deflexicosta,
Sandberger, that these seem sufficient reason to refer it (presumptively) to that
species.
C. continens, var. rudis, Hall, seems only to differ from Sandberger’s figure in
being more strongly ornamented, and being rather shorter in shape, and in these
points perhaps more nearly resembles our specimen.
Affinities—Of the species described by d’Archiac and de Verneuil it seems
most nearly to resemble C. ornata,’ but its strie are not so strongly angulated,
while those of C. Brongniarti, d’Arch. and de Vern.,’ are centrally continuous.
CO. Salinensis, Whiteaves,® has much coarser and fewer tubercles.

TENTACULITES. 37
Description.—Test conical, rather elongate, regular, slightly oblique. Section
apparently circular. Rate of increase 1 in 8. Surface divided by about twenty-
two sharp, raised, slightly irregular annuli, which are not quite parallel near the
aperture ; with slightly concave, wide interspaces, which are finely and obliquely
striated from right to left (thus / / /) when viewed with the apex at the bottom.
Size—Height 7 mm., width at aperture 2:5 mm.
Locality—A single specimen, mould and cast, from Top Orchard is in the
Barnstaple Athenzum.
Remarks.—The specimen is somewhat crushed, so that it is not possible to be
certain that it was circular in section; and from the roughness and decomposition
of the matrix the oblique striation can only be seen with great difficulty.
It is evidently a Tentaculite, and so closely approaches Tentaculites conicus,
F. A. Romer, of the Wissenbach Slates, that I think it may probably be referable
to that species. The only differences I can see are that the German fossil is slightly
more elongate, increasing at the rate of two in seven instead of two in six, and
that the striation is not seen in the figures. The latter is, however, so very minute
that it might very well not have been noticed, and in specimens from Wissenbach in
the British Museum, Mr. Crick and I discovered a similar striation, though it seemed
direct rather than oblique. The former difference is probably due to the English
shell being a little flattened out. I therefore have little doubt that they are
identical.
Affinities.—This is distinguished from Tentaculites tentacularis, Phillips, sp.,
by its very much lower rate of tapering.
T’. subconicus, Geinitz,’ is much narrower, increasing at the rate of two in
eleven, but Geinitz hesitates whether to regard it as more than a variety. He
states” that 7. annulatus, Schlotheim,’ is very much larger, and that Schlotheim’s.
fig. 8a is Silurian, but fig. 8b is Devonian.
Orthoceras Ausavense, Steininger, is considerably larger and more elongate,
but is otherwise very similar in general appearance.
T. dwrus, Ludwig,* seems narrower and larger.
T. acuarius, Richter,’ as given by Kayser, has fewer annuli, and the striz are:
longitudinal, not oblique.

Shell tubularly conical or slightly curved, very elongate; walls rather thick,

It is very doubtful whether there is any reason for separating this group from
Tentaculites proper, on account of its smooth, simple interior, thicker walls, &c.

Description.—Test very elongate, conical, circular in section, increasing at the
rate of about 1: 20, internally smooth, externally banded by very numerous,
regular, elevated, rather distant annuli, about five or seven in a space equal to
width, and with a few finer irregular striz. Structure rather thick.
Size—An imperfect specimen is 15 mm. long and 2 mm. in diameter.
Localities.—A slab in the Porter Collection contains six imperfect specimens
from Pilton. Phillips quotes it from Baggy Point and from Meadfoot (near
Torquay).
Remarks.—These specimens are evidently identical with Phillips’s North
Devon shell, though the annuli are generally closer. He regards it as an
Orthoceras, because he considered that he saw septa in some of the specimens.
He remarks, however, “‘ that they are not satisfactory in regard to the siphuncle
and septa,’ and he does not state whether it was in the North or the South
Devon specimens that he observed these appearances. I should have very great
difficulty in regarding those fossils which I have examined as Cephalopods, both
on account of the thickness of their walls and the smooth simple casts of their
interior, which show no signs of septa. The lines indicating septa in Phillips’s
ficure might, I think, easily be accounted for by the shrinkage of sediment in a
long tube. Septa, however, exist near the apical end of 7’. attenwatus, Hall.’

MACROCHILINA. 39
T. tenuicinctus, F, A. Romer, has often broader rings, 7. e. only four in a space
equal to the width, but in other respects seems to agree, as far as can be judged
by Rémer’s figure. As given by Sandberger and Tschernyschew, it is so very much
smaller than the English fossil that it is wnlikely to be identical.
Affinities. —T. glaber, Trautschoid,' is very similar in shape and arrangement,
but the annuli are so fine that the fossil is said to have the appearance of a
Bactrites or a crinoidal tentacle.
Orthoceras, n. sp., Holzapfel,” may be compared as being similar in ornament,
but considerably larger.
2. Orper—PROSOBRANCHIA, Milne-Hdwards, 1848.

present known to have existed.

1. Genus—Macrocuitina, Bayle, 1880.
1. MAcRocHILINA TURBINEA, n. sp. Plate V, figs. 1, 2.
Description.—Shell small, elongate, turbinate, of three or four volutions.
Spire equal to half the height of the shell, convex, the upper whorls being smaller
in proportion than the lower. Suture simple, shallow. Whorls much exposed,
very broad, convex, arching out from the upper suture, flattened on the back,
and slightly incurving to the lower suture. Shell-structure very thin. Surface
smooth.
Size.—A defective specimen is 16 mm. long and 8 mm. wide.
Localities—In the Barnstaple Athenzum is a specimen from Kingdon’s,
Shirwell, and another from Vicarage Well, Pilton.
Remarks.—This species, though imperfectly known, appears characterised by
its turbinate form, resulting from the increasingly disproportionate diminution of
its spire, and by its very broad whorls. The surface is shown to be smooth by a
small fragment of shell remaining on the figured specimen from Shirwell.

40 DEVONIAN FAUNA.
Afjinities.—It appears to be nearest to M. elevata, Whidborne,' from Lummaton,
but to be distinguishable by its still broader whorls, and turbinate instead of
conical spire.
Mr. Roberts seems to have been inclined to identify it with Loxonema linctum,
Phillips, sp. ;? but it appears separable from that shell by its broader and more
exposed whorls, its loftier spire, and its smooth surface.
It is very distinct from all the Carboniferous shells described by de Koninck.
2. MacrocHILINA PUSILLA, n. sp. Plate V, fig. 3.
Description.—Shell very small, rather elongate, of four or five volutions.
Spire conical, elevated, turrited, less than half the height of the shell. Suture
rather deep and subacute. Whorls narrow, very much exposed, rapidly
increasing, convex on the shoulder, rather flattened on the back, and curving in to
the lower suture. Body-whorl large, diffuse, subglobose, rapidly narrowing in
front. Surface smooth.
Size.—Height 3 mm., width 2 mm.
Localities—There are two specimens from Pilton and one from Frankmarsh
in the Porter Collection, and one from Upcott Arch Quarry in Miss Partridge’s
Collection.
Remarks.—It is of course possible that these minute shells may be the fry of
a larger species, but I know of none with which there is reason to identify them.
It seems to me, therefore, that they must be regarded as a new form.
Affinities. —It appears to have a higher spire and less enveloped whorls
than M. wmbricata, Sowerby, sp.;* more convex and less enveloped whorls than
M. subimbricata, d’Orbigny, sp.;* and much narrower whorls than any of the
other South Devon species.
Jt seems to have a higher spire than M. monodontiformis, de Koninck,’ and a
wider body-whorl than M. minor, de Koninck.°

LOXONEMA. 4]
2.° Genus—Loxonema, Phillips, 1841.
1. Loxonema Hatwi,n. sp. Plate V, fig. 8.
Description.—Cast small, elongate, tapering, of seven or eight whorls. Spire
conical, much larger than the body-whorl. Sutures very slight. Whorls nearly
flat and very broad. Apex acute. Surface apparently smooth.
Size.—Height about 12 mm.; width about 4 mm.
Locality—One specimen from Vicarage Well, Pilton, is in the Barnstaple
Athenzeum.
Remarks.—This appears to be an almost perfectly conical shell, the sutures
being very slightly indented, and the whorls obliquely flattened. Though the
only specimen is in a very poor and rather crushed condition, it seems to give
sufficient evidence of its distinctness from any other Devonian forms with which
I am acquainted.
Affinities —It comes very near in general shape to the Carboniferous
Loxonema leviusculum, de Koninck,' but differs in having considerably broader and
fewer whorls, and probably a larger body-whorl. Its mouth is not preserved, so
that its genus can be only decided by its general affinity to other species; and as
numerous similar shapes are referred by de Koninck to Lovonema, I have placed it
in that genus. :
It bears considerable resemblance to Macrochilina ejecta,’ from South Devon,
especially in the breadth and flattening of its whorls, but differs in its more
elongate spire.

which is bounded by a blunt angle at the shoulder, the rest of the whorl being
gently convex. Surface smooth, shell-structure rather thick.
Sile.—An imperfect specimen is 6 mm. long and 2 mm. wide.
Locality.—In the Barnstaple Atheneum are two specimens from Kingdon’s,
Shirwell, and one from Vicarage Well, Pilton.
Remarks —These specimens are portions of an extremely elongate shell, which
increases very slowly, the diameter of the highest remaining whorl being more
than half that of the fifth below it. As far as can be seen they exactly correspond
with the species described by Sandberger, which, as stated by him, is a synonym
of Turritella trochleata, Minster. ‘The latter shell, he says, is different from
Turbonilla trochleata, Geinitz," which certainly seems to have narrower and
more convex whorls than our specimens.
To Rémer’s own shell they bear less likeness, as that is described as finely
striated on the body-whorl, and has perhaps even broader whorls. As, however,
the body-whorls of our specimens seem lost, and the surface of the shell is in
rather obscure preservation, and as Sandberger distinctly describes the whorls as
smooth, there appears to be no reason to separate them on that account.
A kindred specimen in the Woodwardian Museum from west of Saunton Court
is noteworthy, though it is too poor for identification. Three or four whorls are
seen, which increase much more rapidly in height than in width, so that the
lower whorls are one and a half times as high as wide. Possibly it is only a
distorted variety of the present species, but it presents great similarity to species
of the genus Subulites, to which it may perhaps belong.
Affinities—The very similar specimen figured by Frech’ appears from his
description to be a Murchisonia, having a sinus-band.

Localities—There are several small specimens in the Woodwardian Museum
from the west of Saunton Court.
Remarks.—These specimens, which are in a very poor state of preservation,
seem very similar to the fossils from Lummaton and Wolborough, which I have
referred to this species.
Affinities.—They differ from the Shirwell specimens referred to L. trochleatum

in being much shorter shells with fewer, narrower, and more rapidly increasing
whorls.
Their smooth surface at once distinguishes them from L. Hennahianum,' to which
they have been referred, as well as from Holopella antiqua, Goldfuss,’ sp., which I
formerly confused with that shell. Since describing certain Lummaton fossils *
under the name of H. Hennahiana, Sowerby, I have seen the type specimen of that
species in the Museum of the Geological Society, and find that it is evidently distinct
from them. It is very much more coarsely ribbed than they are, and is more
nearly akin to L. nevile, Phillips. Those Lummaton shells ought therefore to bear
the name Holopella antiqua, Goldfuss, sp., instead of H. Hennahiana, Sow., which
must be restricted to the Plymouth species.

Description.—Shell large, many-whorled, subulate, very elongate, with
apparently rather undulating sides to the spire. Apex aciculate. Spire consisting
of ten or eleven very broad whorls, which are higher than the width of the shell
near the apex, and gradually diminish in ratio, so that the height of the tenth
whorl is about two-thirds of its width. Suture simple, shallow, obtuse. Whorls
sloping from the suture in a sigmoid curve, the upper part being slightly and
obliquely concave, and the lower part wide and convex ; ornamented with about
twelve very large, prominent, transverse, rounded ribs, which are largest in the
central parts of the whorl, and are rather oblique and slightly sigmoid, and so
arranged that they frequently form continuous ribs down the spire. ‘‘ Mouth
roundish.”
Size.—A specimen in the Museum of Practical Geology measures 45 mm. high
by 11 mm. wide.
Localities.—There are four specimens from Braunton Down in the Museum of
Practical Geology, and one from Frankmarsh in Mr. Hamling’s Collection. A
very poor cast from Kingdon’s in the Barnstaple Athenzeum appears to belong to
this species.

44 DEVONIAN FAUNA.
Remarks.—This beautiful species is well described and represented by Phillips
in the ‘ Pal. Foss.,’ but it appears to be distinct from the Yorkshire LD. rugiferum
(Ph.),’ with which he identifies it. It is distinguished by the fact that the ribs are
continuous over the whole surface in the adult shell, as well as in the young form.
This distinction is observable even in Phillips’s own descriptions of his two shells.
The evanescence of the upper part of the ribs in adult shells in the Carboniferous
species is still more clearly seen in de Koninck’s figures,’ who separates the
Devonian form from it on the authority of d’Orbigny under the name of
DL. anglicwm. On the other hand, in all the Devonshire specimens of L. anglicum,
even in the largest which I have seen, the continuity of the ribs is clear; and
these ribs also seem slighter, more continuously uniform in size, and rather more
flexuous. The same characters are shown by both Clarke’s and 'Trenkner’s figures
of the German Devonian shell.
At the same time the two forms have many characters in common, and it is
quite possible that the examination of a larger series of examples than we have at
present might break down the line of distinction between them.
Affinities. —L. angulosum, F. A. Romer,’ is a shorter, fewer-whorled shell, with
more arching ribs.
Holopella moniliformis, F. A. Romer,* differs in having its ribs twice as
numerous, and twice as fine.

volutions, which are less than half exposed. Sutures shallow, obtuse. Body-
whorl more than two-thirds the total height of shell, voluminous, convex. Mouth
pear-shaped, longer than wide, entire, acute behind. Inner lip sigmoidal,
somewhat produced below, where it forms a spurious columella, and covered with
a spreading callosity. Umbilicus apparently closed. Surface smooth.

NATICA. 45
Size.—T wo specimens measure respectively 14 mm. high by 12 mm. wide, and
18 mm. high by 16 mm. wide.
Localities—In the Barnstaple Atheneum are two casts and one mould from
Sloly, and in the Museum of Practical Geology, seven casts from the Marwood
beds, and four from “ Pilton beds, Croyde Bay,” besides another poor specimen
from Croyde, which appears to have come from a higher horizon. A minute cast
(fig. 13) from the Cucullzea beds of Baggy Point, in Mr. Hamling’s Collection,
which has a very low spire, seems to be the young form of this species.
Remarks.—These fossils have been variously referred to Natica meridionalis,
Macrocheilus imbricatum, and Pleurotomaria, but they certainly have nothing to do
with either. With two exceptions they have a red ferruginous matrix, indicating
that they came from the top of the Sloly beds. The surface is seen from the mould
to be distinctly smooth. ‘I'he shape of the mouth is well shown in some specimens,
the outer lip curving regularly to the front, until it meets the inner lip, where it
curls round, forming the free margin of a long oblique cylinder of shell, which is a
kind of spurious columella. The height of the spire is rather variable, and
probably increases with age. This species is named after Townshend M. Hall,
Hsq., F.G.S., who made the Collection now in the Barnstaple Athenzeum.
Affinities—It is easily distinguished from N. meridionalis, Phillips,’ by its
smoothness, and its greater size and shortness.
Natica striolata, F. A. Romer,’ differs in being finely striated, and in having a
rather higher spire.
Natica purpura, F. A. Romer,’ is much more elongate, and has a much higher
spire.
Naticopsis elegantula, Hhlert and Davoust* (which appears to agree generically),
is very similar to the young form of our shell, but seems distinguished by having
transverse and also fine longitudinal strie.

46 DEVONIAN FAUNA.
Size.-—Height 2 mm., width 1°5 mm.
Localities.—Baggy (vide Phillips). One or two small casts from Ironpost,
near Dulverton, in my collection, appear to belong to this species.
Remarks.—I1 have not met with any undoubted specimens of this shell, but the
above-mentioned casts probably belong to it. They are globose shells with half-
exposed, quickly-increasing whorls, which (in the cast) are convex on the shoulder
and nearly flat on the broad back. They agree with Phillips’s figure in dimensions,
except that perhaps they are slightly wider.
Affinities—From Naticopsis Hallii they differ in being much smaller, less
oblique, and more elongate and turrited.

Remarks.—Mr. Porter’s specimen undoubtedly agrees, I think, with
Wolborough and Lummaton fossils referred by me to this somewhat doubtful
species. ‘The body-whorl is deeply concave below and very much flattened.
The apex would seem to be much closer to the plane of the mouth than it is
in the South Devon specimens.

Locality.—There are two specimens in the Porter Collection from Pilton.
Remarks.—One of Mr. Porter’s specimens is a fine though slightly distorted
cast, and appears accurately to agree with the South Devon form. The second is
a mould, and is consequently doubtful, as the shape of the upper part of the whorl
is hidden.
The English fossils closely resemble and are midway between Maurer’s two
species, C. dormitans and C. Hainensis. These two species seem to differ only in
the length of the body-whorl, and the latter of them itself is seen to vary
considerably in that particular. If the three forms are identical, C. dormitans
would be its rightful name. It may, perhaps, be well for the present to leave
them unblended, as in the upper part of the inner side of the English specimens
is a strong longitudinal fold not seen in the German specimens, and we have not
at present sufficient material to show whether this is an accidental or permanent
character.

Size.—Height 8 mm., width 17 mm., depth 17 mm.
Localities—In the Barnstaple Athenzeum are three casts from Top Orchard,
Croyde Bay, and Pilton respectively.
Remarks.—These specimens are not very clear, being too much crushed and
obscured by matrix to be easily identified. In its present condition the best
preserved specimen so closely resembles C. compressus, especially as figured by
Kayser from Belgium, that it seems most probable that they are identical.
Affinities.—From South Devon specimens of C. rostratus, Trenkner, it differs
by its less flatness, by the concavity of its lower side, and by indications of longi-
tudinal folds near the mouth. It is quite possible that, as Holzapfel asserts, 0.
rostratus may prove to be only a variety of C. compressus; but I can by no means
follow him in uniting such totally distinct shells as Diaphorostoma (= Platyo-
stoma) ? sigmoidale, &c., with the latter species.
48 DEVONIAN FAUNA.
C. Zinckeni, F. A. Romer,’ as given by Barrois,? has a less incurved and
rounded apex, and a much more rapidly increasing whorl.
2. Sub-genus—Ortuonycuta, Hall, 1843.
1. OrTHoNYCHIA ROTUNDA, n, sp. Plate V, figs. 19, 19 a.
Description.—Shell rather large, elevated, campanulate, not involute. Apical
extremity small, bent forward ; the perpendicular from the apex to the plane of
the mouth falling within the aperture at one-third of the diameter from its front or
inner side. Whorl very rapidly expanding, indented by four indistinct shallow
depressions, which run from near the apex to the corners of the mouth. Mouth
very wide, expanding, sub-quadrate, considerably wider than long, with a rather
undulating margin, which is lobed by the indistinct concavities at the corners.
Surface apparently rather irregular, and covered with coarse undulating growth-
lines,
Size.—Height 24 mm.; width across mouth 26 mm., from mouth to apex
15 mm.
Locality.—A single specimen from Pilton is in the Porter Collection.
Remarks.—This fossil, while approaching Orthonychia quadrangularis, mihi,*
from South Devon, appears to differ specifically by having a more central and
recurved apex, a more oblique inner side, arougher surface marked with undulating
erowth-lines, and a less quadrate mouth, which is undulated by several concavities
round the margins. The apex itself is defective both in the mould and cast of our
specimen.
Affinities—It approaches Platyceras dubiwm, Barrois,* but seems to differ in
being less transverse and less botryoidal, and in having a recurved apex.

Description.—Shell elongate, not involute, very variable. Apex blunt, vertical,
situate somewhat in front of the perpendicular from the centre of the plane of the
mouth. Whorl more or less conical or fusiform, increasing with variable rapidity,
and generally bearing several concavities and convexities, which radiate from the
apex, and which render the oral margins irregularly lobate. Mouth large, sub-
oval. Surface apparently marked by indistinct growth-lines.
Size.—Height 12 mm., width 12 mm.
Localities—There is a specimen from Sowden, near Barnstaple, and one from
Top Orchard, in the Barnstaple Athenzum; another from Top Orchard in the
Woodwardian Museum; and three, respectively from Pilton, Fremington, and
Marwood Parish, in the Porter Collection.
Remarks.—The above specimens vary very greatly in shape. No two of them
G
50 DEVONIAN FAUNA.
are alike, and the great difference in apical height may be seen by comparing the
two first figures on Pl. VI. No doubt this is partly due to pressure during
fossilization, but the amount of natural variation was evidently very great.
Nevertheless, there do not appear to be any definite characters by which any of
them might be specifically distinguished from the rest, and there seems every reason
to suppose that they all belong to a single very variable species.
This view is borne out by a comparison with the foreign forms described by
F. A. Romer, with which our English specimens evidently agree. They are shown
by Kayser to form part of an extremely variable species, to which he gives the
name C. hercynicus, but which, as it appears to me, the laws of nomenclature oblige
us to call either C. Bischofii or CO. acutus. The limits which Kayser assigns to his
species are still wider than those shown by our Pilton specimens. There is no
English evidence of the elongate CO. acutissimus or the smooth C. selcanus which he
includes among its varieties. Hyen, however, excluding the two latter forms, the
variation of the German shell is fully as great as ours.
Barrois, it is true, re-divides Kayser’s species, but he intimates that he does so
simply on artificial grounds, and it seems possible that some of his other forms,
besides those enumerated above, may also belong to it.
Tschernyschew’s P. cultellus is a flattened form almost exactly like the
specimen here figured on Pl. V, fig. 20, and cannot possibly be specifically dis-
tinct from that shell.
C. conicus, Hall, seems exactly to correspond.
The American Carboniferous form Platyceras quincyense, McChesney, appears
to have its base more oblique, so that the front margin seems perpendicular to it.
This, if not a mere accident, is possibly not more than a varietal difference. It
seems to fall well within the limits of the present species, but its apex is unknown.
One of Mr. Porter’s Pilton specimens is interesting from the fact that it is
attached to, and seems totally to envelope, a specimen of Actinocrinus Porteri.
Affinities.— Platyceras Lorieri, de Verneuil,’ is distinguished by its whorl being
much more incurved and considerably overhanging the inner margin of the mouth.
Platyceras dentalium, Hall,’ differs by having the longitudinal ribs and furrows
twisted instead of straight.
Capulus quadratus, Maurer,’ seems distinguished by its quadrate section, its
sharp apex, and its perpendicular inner side.

ACLISINA. 5]
The Carboniferous C. rectus, de Ryckholt,’ approaches so close as to show no
points of difference in the original figure; but, as given by de Koninck,’ who unites
with it C. corpuratus, de Ryckholt,’ it is distinguished by having a sharper, more
regular and curved apex, and a convex back. De Koninck’ also doubtfully joins
to it O. subplicatum, Meek and Worthen, which seems indistinguishable from low
forms of the present shell.

Localities.—Three specimens from Kingdon’s, Shirwell, are in the Barnstaple
Atheneum.
Remarks.—These fossils, though almost entirely in the form of casts, seem
undoubtedly to correspond with the South Devon shell. A small portion of the
surface remaining on one of them shows the oblique transverse strize characteristic
of the species.
2. Genus—Acuisina, de Koninck, 1881.
This genus was formed by de Koninck for elongate shells with convex
spirally striated walls; oval mouth; smooth, entire, and unexpanding outer lip ;
slightly thickened and unbent columella; and imperforate axis.
He distinguishes it from Murchisonia by the absence of a sinus-band; from
Loxonema by its spiral strie; from Turritella by its more convex whorls and
deeper suture ; andfrom Aclis by its simple columella.

52 DEVONIAN FAUNA.
1. ACLISINA LONGISSIMA, n. sp. Plate V, fig. 10.
Description.—Shell minute, aciculate, of very numerous whorls. Whorls nearly
evenly convex, very narrow, very slowly increasing, much exposed. Sutures
simple, rather deep. Ornament consisting of six fine, acute, elevated, distant,
spiral threads, placed at equal distances on the whorl, and separated by wide
concave interspaces.
Size.—A fragment with seven whorls is about 3 mm. long.
Locality.—There is a specimen showing seven whorls in the Porter Collection
from Pilton.
Remarks.—This tiny fossil differs from M‘Coy’s description of Loxonema
polygyratum, from the Yellow Sandstone Group of the Irish Carboniferous, by
having six ridges instead of five, by having narrow whorls, and by being still
more aciculate. De Koninck regards that species as belonging to Aclisina, and
not to Murchisonia.
Affinities.— Aclisina multicristata, Ehlert,’ is distinguished by having decidedly
more numerous spiral ridges.
From Murchisonia similis, Trenkner,’ it differs in being much more aciculate
and having more numerous ridges.

in section, very convex at the shoulder, gently convex on the back. Sutures deep
not wide. Umbilicus very large, and moderately shallow.
Size.—Approximate measurements: width 6 mm., height 2°5 mm.
Localities—In the Barnstaple Museum are four specimens from Frankmarsh,
one from Kingdon’s, Shirwell, and two from Vicarage Well. In the Porter
Collection are several specimens from Pilton ; in the Museum of Practical Geology
one from Brushford; in my Collection one from Frankmarsh; and in Mr.
Hamling’s Collection, one from the Kiln, Croyde Bay.
Remarks.—These shells evidently belong to one of the species included by
Phillips under the name Hu. serpens, viz. that represented by his figures 172, d, e.
They are perfectly distinct from the much larger species which is common in
South Devon, and which is, as I believe, generally regarded as Hu. serpens,
although Phillips’s description had evidently chief reference to the present shell.
To that larger species I have, therefore, proposed to restrict Phillips’s name; and
consequently it is necessary to find some other term for the Pilton form.
This species is distinguished by its uniformly small size, by its spire being
definitely, though slightly, elevated above the body-whorl, and by the section of
its whorls being almost subangular, and as long or longer than wide. It shows
very little variation in size or general shape. It is decidedly gregarious ; upon
one small slab I have counted seven specimens. But, though evidently very
common, I have not been fortunate in obtaining good specimens for figuring, and
the one which I have had drawn is a small imperfect cast, not giving specific
characters as definitely as could be wished.
Affinities.—It differs from all the South Devon forms in other points beside
size. Its spire is more elevated than that of Philowene levis, and less so than that
of Hu. Dionysit.
2. HUOMPHALUS, sp.
Remarks.—In the Barnstaple Athenzeum is a large specimen about 15 mm. in
diameter from Vicarage Well, Pilton, which is too imperfect for specific deter-
mination, but appears to be quite distinct from the small species common in
these beds. Only three fourths of the outer whorl remain. It appears to be
discoidal in shape, to have a sunken spire, and to be perfectly circular in the
section of the whorls.
D4 DEVONIAN FAUNA.
2. Genus—Ruapuistoma, Hall, 1847.
These are small low shells, with a rather small umbilicus, which often bears a
small marginal keel. The mouth is sub-trigonal. The whorls bear a narrow
band produced by a sinuosity in the aperture. The surface shows growth-lines
or fine crenulations at the suture. It occurs in the Lower Silurian and the
Carboniferous, and de Koninck remarks on its supposed absence from Upper
Silurian and Devonian rocks.
It has generally been regarded as belonging to the Plewrotomariide ; but
de Koninck, and perhaps Hall, are inclined to class it with the Solariide.
Possibly it really goes to show the relationship between these two families.
Fischer * regards it as synonymous with Scalites, Conrad, 1842.

Description.—Shell very small, sub-conical, but so much depressed as to be
nearly discoidal. Spire consisting of about five rather slowly increasing volutions,
much enveloped, the lower walls covering nearly half of the upper half of the
whorl above. Apex elevated, sharp. Suture slight, facing upwards. Whorls, in
section, much wider than high ; in outline, turning suddenly outward from the
suture and spreading out obliquely and almost flatly to the centre of the back,
where they curve round so suddenly as almost to form a blunt rounded angle, and
then proceed with a slight convex curvature to the umbilicus. Ornament consist-
ing of a row of strong, short, transverse ridges, close to the suture, which vanish
immediately ; the rest of the surface showing no ornament except occasionally
very slight and indistinct continuations of some of the striz of the sutural crown,
which arch backwards, and then perhaps turn suddenly forwards just above the
angle of the back. Umbilicus small, bordered by a small sunken keel.
Size.—Height 4 mm., width 7 mm.
Localities.—A specimen from Pilton is in the Porter Collection; three others
1 1887, Fischer, ‘Manual Conchyl.,’ p. 851.
RHAPHISTOMA. 55
from the west of Saunton Court in the Woodwardian Museum; one from Ironport
in my Collection ; and one from Kingdon’s, Shirwell, in the Barnstaple Athenzeum.
Remarks.—This little species so exactly agrees with the Carboniferous shell
from Belgium, Scotland, and the Isle of Man, described by de Koninck as Rhaphis-
toma junius, that there can be no doubt of their identity. The agreement extends
both to shape and markings, umbilicus and umbilical keel. Almost the only
difference is that our shells are decidedly smaller, and that de Koninck does not
notice the downward continuation of the sutural corona, which is very obscurely
observable in one only of our specimens. De Koninck also mentions a depres-
sion like a sinus-band, which, however, he regards, not as a true sinus-band, but
as a band similar to that seen in some forms of Huomphalus, in the neighbourhood
of which he therefore places the genus. In our shells this character cannot be
distinctly observed.
This species seems to bear very much likeness to the Plewrotomaria expansa,
Phillips, of the ‘ Pal. Foss.,’ and it is most probable that Phillips’s figure represents
a specimen of it. That specimen I have not been able to find. In its figure
there are indications of a ribbed sinus-band, which certainly does not exist in our
present species. On comparing, however, this figure with his description (which
is quoted from the description of Pl. expansa in the ‘ Geol. Yorks.’) it seems most
likely that this appearance in the figure was due to a confusion with the adjoining
matrix. At all events, itis pretty clear that the shell he described from Devonshire
is quite distinct from the true P/. expansa, Phillips, of Yorkshire, which is clearly
a Pleurotomaria, is both spirally and obliquely striated, and has no signs of any
sutural crown.
Whether Pl. gracilis, Phillips, is more than a variety of this species is question-
able. Our specimens seem intermediate between Phillips’s figures of his two
species, but I have been unable to find the types of either, and the data given by
him are too meagre for a satisfactory conclusion. If, however, the species which I
have described from Lummaton is really identical with Phillips’s Pl. gracilis, then
that shell is certainly distinct from the present, and differs from it by having a
more distinct and elevated sinus-band.
Affinities.—Natica discus, F. A. Rémer,’ is very similar in shape, but is micro-
scopically striated. It perhaps belongs to the same genus, but is so much larger
that it is probably a distinct species.
Trochus owygonus, F. A. Romer,’ has a much sharper basal angle, and perhaps a
slightly lower spire.
The flat variety of Plewrotomaria crenatostriata, Sandberger,’ is very similar,

Description.—Shell small, trochiform, turrited, of equal height and width.
Spire elevated, rather slowly increasing, consisting of at least four whorls.
Suture obtuse. Whorls narrow, sloping out from the suture in a concave curve
to the shoulder, where they suddenly turn through a blunt angle, and then
proceed perpendicularly downwards for about the same distance to the lower
suture. Sinus-band situate on the shoulder, and consistinz of an excavate groove,
which is bounded above and below by a thread-like ridge, and has a row of
small beads or nodules along its centre. Ornament consisting of (1) a row of
small nodules, halfway between the suture and the sinus-band, and a second row
of still smaller nodules halfway between this first row and the sinus-band; (2) two
equidistant rows of small nodules, the upper row of which is the smallest, situate
upon the lower or perpendicular part of the whorl; and (3) minute, transverse
elevated threads, which arch gently backwards on the upper part of the whorl, and,
PLEUROTOMARIA. 57
' recurving in the sinus-band, become straight and perpendicular across the lower
part of the whorl. Cast of shell showing signs of a deep sinus at the mouth.
Size.— Height 10 mm., width 10 mm.
Localities—There are five specimens (including a very doubtful cast) in the
Barnstaple Athenzeum, from Kingdon’s, Shirwell; two doubtful casts in the
Porter Collection, from Pilton; one in the Woodwardian Museum from Barn-
staple; and a large cast in the Museum of Practical Geology from Braunton Down.
Remarks.—I have long believed that the shells figured by Phillipsas Pl. aspera,
Sowerby, included two species, and in 1889 I suggested the name PI. distinguenda
for those, which specifically differed from Sowerby’s type in the Woodwardian
Museum. It appears, however, that Tawney in 1873 pre-occupied that name for
an Oolitic species, and therefore it requires to be changed.
With this form, as figured by Phillips, these North Devon fossils closely agree,
and I believe them to belong to a well-marked species. Our described specimen
retains the upper whorls in a beautiful state of preservation, but its body-whorl is
defective. It is distinguished from Pl. aspera by the spire being more angular or
step-shaped, and by the sinus-band being at the shoulder instead of near the lower
suture.
M‘Coy' unites Pl. aspera to Pl. interstrialis, Phillips.” I have compared speci-
mens of the latter with the present shell, and believe them to be quite different.
In Pl. interstrialis the whorls are more rounded, the spiral marks are more
numerous and different, and there are no nodules in the sinus-band. From the
true P. aspera it is still further removed, though in a different direction.

curve over the shoulder, and becoming slightly concave or sigmoidal at the centre
and widest part of the whorl, at which is situated a very elevated rounded sinus-
band, and below which the outline of the body-whorl passes round with a circular
curvature to the umbilicus. Umbilicus wide and deep. Ornament, above the
sinus-band, consisting of three or four equidistant, very narrow, distant, spiral
threads, between which alternate similar finer threads, crossed by slightly oblique
and sigmoidal, similar and similarly-placed transverse threads, so as to form hollow
squares, which become rather nodose at the corners by the intersection of the
threads. Sinus-band situated close to the lower suture, and bounded by two very
minute entire threads, between which it is very elevated and rounded, and crossed
by numerous close rounded ridges, which are probably again crossed by about six
similar spiral threads. Ornament of the body-whorl below the sinus-band very
similar to that above.
Size.—Height 13 mm., width 12 mm.
Localities.—In the Barnstaple Athenzum is one poor specimen from Vicarage
Well, and one from Top Orchard; in the Museum of Practical Geology are two
(a specimen and a cast) from South Petherwyn, and an external cast from
** Marwood Beds, Hast of Barnstaple” ; in the Woodwardian Museum is Sowerby’s
original type, and a fine cast from South Petherwyn, and a poor specimen from
Top Orchard ; in the Porter Collection a fragmentary specimen from Roborough.
Remarks.—The above description is taken chiefly from South Petherwyn shells.
The figured mould from Barnstaple differs slightly from the rest. It has closer
and slighter transverse threads, and three subsidiary minute threads between the
larger spiral threads, and its sinus-elevation is sharper. There seems considerable
variation in height. The cast from South Petherwyn, in the Museum of Practical
Geology, is so like Phillips’s fig. 177*, that it may be its original ; if so, that figure
belongs to the present species, and not to Pl. victrix' as I formerly thought possible.
Affinities—Pl. Hamlingwi is distinguished by the section of its whorl being
approximately quadrangular instead of triangular, and by its sinus-band being
situated high on the shoulder and followed below by a broad perpendicular back,
on which are several distant spiral threads.
Pl. minima or minuta, F. A. Romer, is a cast very similar to that represented
by fig. 12, and might very well belong to this species; but, as its ornament is
undescribed, it is impossible definitely to identify it. It occurs in the Wissenbach
Slates.
Pl. Orbigniana, D’ Arch. and de Vern,’ and its variety, Pl. Beaumonti, d’Arch.
and de Vern.,’ are distinguished among other points by their sunken sinus-band.

particulars.
4, PLEUROTOMARIA, sp. Pl. V, fig. 9; and Pl. VI, fig. 8.
Description.—Shell minute, very elevated, of several rather broad and slowly-
increasing, convex whorls. Suture deep. Surface ornamented with several high,
unequal, subacute, concentric ridges, which are crenulated by more numerous
elevated, rounded, transverse threads, arching backwards from the upper suture,
and very strong on the sinus-band, which appears to be elevated, rounded, and
situated at or about the centre or wider part of the back in the body-whorl.
Size.—Length about 4 mm.
Localities.—In the Porter Collection are two imperfect specimens from Pilton.
Remarks.—It appears to me that these specimens are more likely to belong
to some very lofty species of Pleurotomaria than to Murchisonia, but their state
of preservation is too imperfect to permit any definite opinion to be formed at
present upon them.

arching out obliquely from the suture with a gentle curvature to the widest part,
which is three-quarters the way down, and then rapidly curving in to the lower
suture. Sinus-band broad, elevated, concave, angular, situated near the base of
the whorl.

Size.—A fragment containing three whorls, measures 9 mm. long, and 5 mm.
wide.
Locality.x—One specimen is in the Porter Collection from Pilton; and one in my
Collection from Pouch Bridge. Phillips records it from Brushford and South
Petherwyn.
Remarks.—When describing M. turbinata, Schlot., from South Devon, I was
unable to find the specimen which Phillips figured in his ‘ Pal. Foss.’ under the
name of M. angulata, Ph., and it then appeared to me that it might very probably
be a crushed or contorted specimen of Schlotheim’s most variable shell. Since
then, however, I have obtained specimens which exactly agree with Phillips’s figure,
and show that it represented the true form of the shell. These prove it to be
undoubtedly a distinct species, distinguished by the great breadth of its rapidly
increasing whorls, by its sinus-band being situated very near the lower suture,
and by the obliquely convex shape of the whorls, as well as by its very small size.
The sinus-band is formed of two coalesced keels, but my specimen, probably
from its imperfect state, does not show the lower (third) keel described by Phillips.
Miss Donald, who, as well as Mr. J. F. Whiteaves, discusses the various shells
under the name M. angulata, shows that the Devonian species is distinct from the
two Carboniferous species to which Phillips had previously applied the same name.
Hence it must bear the name under which D’Orbigny long ago separated it from
them.
While, however, these two references to Phillips and D’Orbigny must be
removed from the list of synonyms of M. turbinata, there seems no doubt that the
M. angulata of d’ Archiac and de Verneuil, Goldfuss, and other later authors is dis-
tinctly a variety of Schlotheim’s shell, and has nothing to do with the present
form.
2. Murcuisonia, sp. Plate VI, fig. 15.
Size—Height 18 mm., width 9 mm.
Locality.—An obscure cast from Baggy Point is in the Museum of Practical
Geology.
Remarks.—The above-named specimen appears to me to be quite distinct from
M. anglica. It is much larger, its whorls are much narrower, and the sinus-band
seems only slightly below the centre of the whorls. It thus is much more like
M. turbinata, and perhaps may be the cast of one of the varieties of that shell ;
but it is in much too imperfect a condition to make it safe to refer it to it
without further evidence.
MURCHISONIA. 61
It may be noticed that the sutural angle varies considerably, the spire having
been imperfectly coiled as often happened in M. turbinata.

Description.—Shell very small, elongate, conical, turrited, of seven or eight
slowly increasing whorls. Apex sharp. Sutures simple, rather shallow. Whorls
rather narrow, convex, much exposed. Ornament consisting of a fine elevated crenu-
lated thread immediately below the suture, two other threads bounding the sinus-
band, which lies just below the centre of the back, and a fourth thread not quite
half-way from the sinus-band to the lower suture; the whole crossed by micro-
scopical, close and regular, transverse lines, which are nearly straight, and slope
very obliquely backward from the sutures, and then arch to meet on the sinus-
band. Body-whorl possibly rather larger than the others. Umbilicus apparently
shallow and concave.
Size.—A specimen retaining the four lowest whorls is 5 mm. high by 2 mm.
wide.
Tocalities.—There are five specimens (moulds) from Vicarage Well, Pilton, in
the Barnstaple Athenzum.
Remarks.—The three lower longitudinal threads divide the whorl into four
bands, and are so placed that the two central bands, the upper of which is the
sinus-band, are rather narrower than the upper, and sometimes than the lower,
marginal band. ‘The transverse ornament is very minute, and only visible in good
lights. I did not observe it till after the figures were drawn, and, in fact, it is
too fine to be represented in them. It is, however, very regular and definite, and
proves the shell to belong to Murchisoma.
Our specimens appear to agree with T'renkner’s figure of M. svmilis, but to be
less aciculate than the fossil given by him as M. quadricincta, and refigured by
Clarke. The latter name has been applied by Pacht’ to another small species
which is perhaps distinguished by being shorter, by having more angular whorls,
and by a different arrangement of the longitudinal threads.

Afinities.—Aclisina longissima seems distinguished by its much more aciculate
form, and more numerous threads, and by the absence of transverse lines and
sinus-band.
Lowonema gracillimum, Whiteaves,' is a longer shell with broader whorls,
direct transverse threads and no sinus-band.
M. bistriata, F. A. Romer,’ seems longer and more conical, and has only two
spiral threads. As given by Geinitz,’ it is much more like our shell, but is described
as having only three spiral threads.

Surface ornamented with distant, strong, rather unequal, radiating threads, crossed
by finer and closer arching threads or lines of growth.
Size.-—About 2°5 mm. wide and 2°5 mm. high.
Locality.—One tiny specimen from Pilton is in the Porter Collection.
Remarks.—Our specimen is decoriated, and partly embedded in matrix. The
striz are clear near the mouth, but the ornament of the keel cannot be traced.
It is possible from its small size and general appearance that it may be a young
shell.

BELLEROPHON. 63
It closely resembles and probably belongs to the Devonian Bellerophon
elegans, d’Orbigny, although its ornament seems to be set more closely. In that
respect it agrees with the Carboniferous B. clathratus, d’Orbigny, which its
describer distinguishes from the former species by its having only three
longitudinal threads on the keel instead of numerous finer lines. These two
species de Koninck unites; but he separates from them B. elegans, d’Archiac
and de Verneuil, on account of its wider and flatter keel. It appears to me
that in that particular our fossil agrees with B. elegans, as originally given by
d’Orbigny, and comes exactly half-way between d’Archiac and de Verneuil’s and
de Koninck’s versions of it. On the whole it may prove that the species was
variable and long-lived.
Affimties.—From Euphemus Baruwmensis, the only North Devon species at all
resembling it, it is at once distinguished by its open umbilicus and elevated keel.
B. Vogulicus, Tschernyschew,! is a narrow, more rapidly-increasing form with
a closed umbilicus.
2. BELLEROPHON LABYRINIHODES, n. sp. Plate VIII, figs. 1—2 b.
Description.—Shell small, convex, globose, horizontally symmetrical, probably
of rather numerous whorls. Umbilicus rather large, expanding laterally. Whorls
nearly evenly convex, bearing a central narrow elevated sinus-band, which is
bordered by elevated threads and crossed by minute arching strie. Surface-
ornament very minute, so as to be invisible to the naked eye, consisting of close
zigzag rows of puncta between sharp ridges, which are scored by the puncta,
about four zigzags occupying each side of the shell-surface ; beneath which are
sometimes seen indications of larger transverse arching growth-lines and radiating
ribs.
Size.—Height 11 mm., width 8 mm. :
Localities—In the Barnstaple Athenzeum are several specimens on two slabs
from Kingdon’s, Shirwell, and one from Top Orchard, all of which are casts
except one. Inthe Museum of Practical Geology is a specimen from Baggy Point.
Remarks.—This is a very beautiful and highlv ornamented species. The orna-
ment is microscopical, but it is much in the style of B. Hicksii,? except that it is
much finer and more definitely zigzag. Roughly speaking, the pattern is reticulate,
the zigzaging being only visible in some lights. The Baggy specimen is rather
more coarsely and definitely marked, and under the superficial ornament it shows
signs of transverse ribs like those of B. costatus, and radiations like those of
Hu. Urii. It is possible that the latter are the true ornaments, and that the finer

pattern may have been superficially super-imposed by a mantle. Occasionally the
cast shows indications of the sinus-band by an obscure elevation.
Affimties—The casts of Salpingostoma? macromphalus, F. A. Romer, sp., from
Kingdon’s, Shirwell, are somewhat similar to this species, though their possession
greatly and rapidly expanding lips, which makes it probable that they are identical
with the smooth-shelled German fossil, clearly distinguishes them ; and the present
shell also differs in being much higher and more definitely globose. It seems to
me that they are undoubtedly distinct.
This species sufficiently approaches d’Archiac and de Verneuil’s version’ of
Bellerophon tuberculatus, de Ferussac, to raise the question whether it might not
be identical. On referring, however, to d’Orbigny’s’ description and figures it is
at once seen to be distinguished by the much finer and less moniliform character
of its ornament. In the latter shell the tubercles are definite, and though a
quincuncial arrangement is mentioned, the elaborate zigzaging of the inter-
mediate furrows is hardly if at all apparent. It is also a much larger shell, and
its whorls seem to increase somewhat less rapidly.

Description.—Cast of shell small, globose, horizontally symmetrical, apparently
of numerous, slowly increasing, involute whorls. Whorls generally very much
flattened on the back and deeply convex on the sides, but occasionally sub-angular
on the back and obliquely flattened on the sides. Umbilicus very small and deep.
Size.—Height 9 mm., diameter through sinus-band 7 mm.
Locality.—In the the Barnstaple Museum are four specimens (including
a slab with indeterminate fragments) from Sloly, and four from Baggy Point. In
the Museum of Practical Geology are six from the Marwood Beds, and eight from
Shirwell (Marwood Beds). In the Woodwardian Museum is one from Baggy
Point.

do not admit of a complete description. The matrix shows that they belong to
the Marwood series. The rate of increase of the whorls is very slow, and in none
of them is there any sign of any labial expansion. In one of the specimens there is
a slight indication of a central depression on the back; and in another (which is
figured on Pl. VIII) there is an equally slight suggestion of a central keel. In the
latter specimen there also appears an oblique flattening of the back on each side
of the median line, which is not usually seen. In one or two cases very faint and
doubtful marks exist, which possibly indicate that it was ornamented in the style
of B. lineatus, Sandberger.'
These appear to be the shells described by Phillips as B. globatus, Sow.,’ from
*‘Marwood, Pilton, Brushford, &c.,” though in his figures the umbilicus seems larger,
and there seems some indication of ornament. The central of his six figures is
the most like our shells. They were separated from B. globatus by M‘Coy on
account of their small umbilicus, and they also differ from it in the slow rate of
increase of their whorls. Whether they are distinct from all the accompanying
shells whose ornament is known cannot at present be positively asserted. They
bear some likeness to young or imperfect specimens of S.? macromphalus of the
Pilton beds, but differ in being smaller, and in having a smaller umbilicus, and no
signs of any labial expansion.
They also approach in general shape B. labyrinthodes, but seem to have more
slowly increasing whorls.
4, BELLEROPHON P sp. Plate VIII, fig. 7.
Description.—Cast of shell small, discoid, oval, flattish. Spire consisting of three
rapidly increasing whorls, deeply sunken, probably very similar above and below.
Whorls vertically narrow, horizontally wide, convex (the convexity being much
greatest on the back), slightly involute (the outer whorl enveloping one-third of
the whorl within). Umbilicus open, with a spiral concavity formed by the suture.
Mouth slightly expanded. Margin of lip convex. Back deeply and evenly
convex, not keeled.
Size —Height about 4 (?) mm., width 6 mm., depth 9 mm.
Localities.—Two specimens from Vicarage Well, Pilton, are in the Barnstaple
Museum.
Remarks.—These specimens are very indistinct and puzzling. They give so

the same name, and his description is definite, though unaccompanied by a figure.

few characters that it is impossible to be sure about their right position. On the
whole it seems most likely that they belong to a discoidal form of Bellerophon.
Affinities —From B. compressus, Sandberger,' which is the same as B. Mur-
chisoni, d’Orbigny,” it differs by having flatter sides and a more convex back.
B. Troostii, d’Orbigny,* is very similar on the back, but much deeper.
In B. capuloides, Maurer,* a sinus-band is visible.
On the other hand, Capulus immersus, Barrande,’ C. contortus, F. A. Rémer,®
and Giebel,’ C. gracilis, Sandberger,* approach it in shape, but their spires do not
seem in any case so regular and complete.
While, again, species of Goniatites often closely resemble it, it does not seem
worth while to compare it with any of them in the absence of any indication of
septa or suture-lines.
2. Genus or Sub-genus—Sa.pineostoma, f. Rdmer, 1876.
This genus is distinguished by having an interrupted or evanescent sinus-
band, a very wide open umbilicus, and a very widely and rapidly expanded simple

Description.—Cast of shell rather large, subglobose, rather flattened, hori-
zoutally symmetrical. Spire elliptically coiled? Whorls flattened on the back,
regularly and moderately convex round the upper and lower sides. Sinus-band
indicated by a central depression in the cast until it approaches the aperture,
where it rather suddenly rises into a rounded ridge. Umbilicus wide, curving
regularly round, continuously with the lateral curves of the whorl. Mouth
expanding rapidly to form broad transverse wings or expansions, so that the
diameter of the mouth is three times that of the height of the shell a short
distance behind it.
Size—Height 40 mm. across the expanded mouth, 14 mm. across the
umbilicus near the mouth; width through sinus-band 24 mm.
Localities.—In the Barnstaple Athenzum are five specimens from Kingdon’s,
Shirwell; and in the Museum of Practical Geology two from the Pilton Limestone
of Marwood.
Remarks.—Though our specimens are all casts, a very minute fragment of
shell remains on one of the figured specimens of them, and appears to show a
minute ridge-like ornament.
This species is either identical with or very near akin to S. macrostoma,
F. Romer; our specimens do not show an unbroken circle in the expansion of the
mouth, perhaps simply on account of their imperfect condition, nor have they
so wide an umbilicus.
Bellerophon macromphalus, F. A. Romer, has, according to his own figure and
description, a very much larger and flatter umbilicus with more numerous narrow
whorls; but, as revised by Beushausen, it seems almost exactly to agree with the
present species. While all the material is confined to casts, it is hopeless to arrive
at certain conclusions, but it seems clear that B. macromphalus and B. macrostoma
are generically identical, and no reason seems assignable why they should not also
be so specifically. The South Devon shells which I described from Chircombe
Bridge show, I think, no difference from the North Devon fossils, except that
they are circularly coiled, and that they are sometimes rather more angulated
round the umbilicus—points which need not be indicative of specific distinction,
as neither of them seems constant.
Affinities. —B. Gostariensis, ¥. A, Romer,’ is said to differ from S. macrostoma,
F. Romer, by its more involute and fewer whorls, the more sudden widening of

the mouth, the strong keel on the back of the expansion, and the much smaller
size of the spire. Whether in these particulars it agrees with the English shell
I am not sure.
It may be noted that figures given by Hall’ of his B. pelops show a similar
keel in the cast, but a regular small round keel in the perfect shell. From our
shells they differ in not having the mouth so extremely expanded.
3. Genus or Sub-genus—Troprpopiscus, Meek, 1866.
This genus or sub-genus contains shells akin to B. trilobatus, Sow., which are
very flat, with very wide and open umbilici, and with a rounded convexity bounded
by two concavities on the back of the whorl, but without any definite sinus-band.
De Koninck proposed to replace Meek’s name by T'ropidocyclus, because Stein
in 1850 had used the name Tropidiscus. As Meek had himself emended the latter
name, which he had used at first, there appears to be no reason for a further
change.
Fischer’ regards Meek’s name as a synonym of Oyrtolites, Conrad, 1838.

Description.—Shell very small, not quite horizontally symmetrical, wider than
high. Spire rapidly increasing. Umbilicus very large. Whorls deeply convex
on the shoulder, then becoming concave till they rise in the central part into a
large elevated convexity, and returning with the same sweep reversed to the
umbilicus. Surface quite smooth, with no signs of sinus-band or ornament.
Size.—Height 7 mm., width 8 mm.
Localities.—In the Museum of Practical Geology are two specimens from
Baggy Point and one from West Angle Bay, Pembrokeshire; and in the Wood-
wardian Museum one from west of Saunton Court.
Remarks.—Whether B. trilobatus, Sowerby, is a long-lived and variable species,
or whether there are several distinct kindred forms bearing the same facies, is a
question on which I have not yet been able to arrive at a satisfactory conclusion.
As figured by Sowerby and F. A. Romer, B. trilobatus is a much more globose
form. Sandberger gives three varieties, acutus, typus, and tumidus ; the first
almost flatly discoidal, the second corresponding to B. bisulcatus, F. A. Romer, and
the third as globose as Sowerby’s types. Of these, Gihlert remarks that he has
collected all three in Mayenne in the midst of intermediate forms. Again, Phillips
gives three varieties from Devonshire, one of which agrees with Sowerby’s shell in
globosity, and this is apparently the one which he quotes from Baggy.
Furthermore, the specimens which I have myself seen agree with B. bisulcatus,
¥. A. Rémer, though they do not seem distinguishable from Silurian specimens in
the Museum of Practical Geology, with which I have compared them.
M‘Coy in 1855 separated the Devonshire shell from the Silurian under the
name B. bisulcatus, Romer.
Beushausen in 1884 treated B. trilobatus, B. bisulcatus, and B. twmidus' as
distinct species, while in 1889 Sandberger’ himself separated B. tumidus from
B. trilobatus. In this he is followed by Kayser * in 1895, who, moreover, describes
a distinct sinus-band with marginal threads on some specimens of B, tumidus from
Pepinster.
The B. trilobatus of d’Orbigny appears exactly to agree with B. bisulcatus,
F. A. Romer, and our specimens.
On the whole it seems best, at least as a provisional arrangement, to treat:

our shell (which may be taken as identical with B. bisulcatus) as a variety of
Sowerby’s species.
At the same time the B. twmidus of Kayser, and perhaps also that of Beushausen,
must, from their defined keel, be regarded as distinct, though there is possibly
more reason for retaining B. trilobatus, var. tumidus, Sandberger, as a variety of
Romer’s shell.
Affinities —De Koninck’s three Carboniferous species of the genus are all
distinguished by elaborate ornament.
B. compressus, Sandberger,' which is the same as B. Murchisoni, d’Orbigny,’
has a striated keel and no lateral concavities.
4. Genus or Sub-genus—Eurnemus, M‘Coy, 1844.
This genus was formed by M‘Coy, and revived by Waagen and de Koninck, for
shells of the type of Bellerophon Uru, Fleming. It appears individualised by
several definite characters, among which may be mentioned the nature of the
ornament, which de Koninck seems to regard as produced by the animal only on
the old parts of its shell, and as taking the place of the smooth callosities seen in
those parts in other genera of the family. The sinus-band is often well marked in
the newer part of the shell, butis more or less obliterated in the striated portion.
De Koninck describes five species from the Carboniferous of Belgium, all of
which seem very closely allied.

simple, erect, very distant spiral lines, which are most distant at the centre of the

structure massive.

EUPHEMUS. a
Remarks.—Phillips figures two specimens, and adds the following particulars :—
aperture very expanded; no umbilicus, no band; ridges crenulated; furrows
crossed by fine lines of growth, retroflexed from the mouth. Interior of the shell
quite smooth.
There is certainly no keel, but there is a slight sign of a sinus-band between
the two central ridges, shown by a faint indication of recurved growth-lines in it.
The lateral lines of growth retroflexed from the mouth are also just visible. There
are no signs whatever in our specimen of the crenulations on the spiral ridges
which are described by Phillips. It seems, however, possible that Phillips’s
enlarged pattern (‘ Pal. Foss.,’ fig. 199 d) may have been taken from this specimen
as well as his other figure, and if so the signs of crenulation in it are deceptive,
being due to a slight fracture of the summits of the ridges.
Affinities.—It is difficult to define the species from the small portion visible in
our only specimen. From the true Hw. Urii,' as restricted by de Koninck,’ it is
distinguished by the absence of an elevated keel. Hu. Orbignii, de Koninck,® has
coarser and closer spiral ridges. Hw. Horioni, de Koninck,* has more numerous
strie. Hu. invitabilis, de Koninck,’ has more unevenly arranged ridges, and is a
flatter shell. Hw. filosus, de Koninck,’ seems to approach nearest to it, but differs
in the same particulars. As, however, our specimen only shows the inner whorl,
it is hard to say whether these distinctions would remain true if a perfect
specimen of it could be compared. At the same time it seems most probable that
they would, and that they are sufficient to give this forma claim to a distinct name ;
especially considering that, as it belongs to a different formation from the above-
mentioned shells, the presumption is that they are distinct. Moreover, though
Roémer’s figure of his Devonian shell is very poor, it shows that, if it represents
the present species, its shape is very different from that of any of the Belgian
forms.
D’Orbigny figured the young shell of Oxygyrus Keraudrem, Rang,’ of which he
remarked that it is so like in shape and ribbing that it would be hard to
distinguish it if it came from beds of the same age, and which he considered to be
evidence of the relationship of Bellerophon to the Atlantide.°

Crass—LAMELLIBRANCHIATA, Blainville, 1814.
The abundance of bivalves in these beds is marked, though except in a few
cases it is rather in the form of a variety of species than a profusion of individuals.
In some cases, especially in the Marwood zone, specimens occur in crowds; for
instance, Cucullea unilateralis, Sowerby, and Ptychopteria Damnoniensis, Phillips,
sp., are evidently gregarious, while Prothyris scalprata, n. sp., completely covers
one rock-surface. In the Marwood beds, however, the number of species is few ;
but as we advance into the Pilton Zone we find, though shells are fewer, species
are greatly increased ; and there, though some are found commonly, most are only
known by one or two examples.
Sixteen species were quoted from this area by Phillips, but of these, five seem
only synonyms. On the other hand, many of his South Petherwyn species are
found also to occur here. Not a few of the fresh forms bring out the relationship
to the American Devonians, and it seems remarkable how often light has been
thrown on our English species by the resemblance, not generally amounting to
specific identity, of Transatlantic shells.
1. Orper—DESMODONTA, Neumayr, 1883."
I. Family—Prezcarvipm, Rudolf Hornes, 1884.
1. Genuws—Panenka, Barrande, 1881.
This genus being known only by its external characters, its position is
doubtful. Fischer includes it and its congeners, Precardtum, &c., in a provisional
family of his sub-order Anatinacea ; Neumayr (1891) places it under his order
Palzxoconcha, Beushausen under Cardioconcha, Zittel under Homomyaria. Pos-
sibly its rightful place will ultimately be found to be near some genera now
included in the enlarged order Desmodonta.
1. PANENKA ANGLICA, n. sp. Plate VIII, figs. 10, 11, lla.
Description.—Shell large, transverse, convex. Umbo small, incurved, facing
forward, and situated at about the anterior third of thelength. Lunule large but
undefined. Surface covered by 35 or 45 regular, even, close-set, rounded rays, of

which the eight or ten situated medianly are decidedly narrower than those on
each side, and which seem gradually to increase in size laterally, and are divided
by concave furrows narrower than the ribs. Transverse ornament consisting of
numerous regular, fine, close, strong, transverse strie or threads, which cross the
ribs as well as their intervals.
Size of a distorted specimen: height 60 mm., length 70 mm., depth 15 mm.
Localities.—An imperfect and distorted specimen from Top Orchard is in the
Barnstaple Atheneum; another from Braunton in the Museum of Practical
Geology ; and a third from Barnstaple in the Woodwardian Museum.
Remarks.—The first two specimens have been regarded as the Avicula
pectinoides, Sowerby,’ but a comparison of the type of that species and M‘Coy’s
description of it with our specimens and with Aviculopecten (Meleagrina) rigida,
M‘Coy,’ which M‘Coy doubtfully identified with it,’ shows that it is quite impossible
for them to belong to it. Moreover the third specimen is sufficiently perfect to
remove all doubt.
On the other hand, their likeness to the lengthy series of species referred by
Barrande to his genus Panenka is so great that there can remain no question
against their belonging to that genus. While, however, their generic position may
be regarded as certain, the very vastness of the numbers of species described from
Bohemia renders it the more difficult to decide whether our crushed and distorted
English shells agree with any of them. At present I know of no Bohemian
species with which it seems safe to unite the present form.
Its chief characteristics seem to be (1) the smallness of the central ribs, five
of which occupy the same space as four of the lateral ribs; (2) the strong, close,
thread-like, transverse striz; and (3) the strength of the ribbing on the latero-
superior parts of the shell.
The Bohemian shell that agrees best with our specimens in the second of these
points is Panenka spheroides, Barrande,* and of it Barrande only figures a single
specimen, whichis as imperfect and distorted as ours. The shell maybe more convex,
and the umbo more central and more elevated than it is in ours, but it is impossible
at present to decide whether these distinctions are valid, the true shape of neither
form being known.
In P. Bohemica, Barr.,° and P. domina, Barr.,° the threading is finer, and the
marginal ribbing generally fainter.

In P. amabilis, Barr.,' the umbo is central and direct, and more acute.
In P. intricans, Barr.,’ the threading is complicated by every fourth thread
being larger.
In P. obsequens, Barr.,® the threading is somewhat similarly complicated and
the umbo more central.
In P. expansa, Barr.,* the ribs, though expanding laterally, become small again
almost immediately.
P. gracilis, Barr.,° closely resembles the specimen in the Barnstaple Atheneum
in shape, and apparently is rather coarsely threaded, but it shows no signs of the
central diminution of ribs. Itis probable, however, that our shell has not retained
its true shape, and the Bohemian shell too has signs of being distorted.
Cardium rigidum, F. A. Romer,’ appears congeneric, but seems distinguished
by having a more anterior umbo, rather more numerous ribs, no transverse
threading, and no central diminution of the ribs.
P. grandis, Whiteaves,’ is much larger and more transverse, and has still
wider lateral ribs, and no transverse threads.
P. potens, Hall,® comes very close, but seems to have a more central and erect
umbo and less strong concentric marks, and its ribs are fainter above.

Description.—Left valve large, transverse, subquadrate, convex. Umbo very
large, wide and prominent, depressed in the centre, much elevated above the hinge-
margin, situated at about the median third of the length. Hinge-margin long,
slightly concave behind the umbo. Anterior margin arched, being oblique from the
umbo to the anterior corner, which is rapidly rounded, and then oblique and
moderately convex in its inferior part. Inferior margin long, slightly oblique, and
convex but depressed in the centre. Posterior margin roundly convex, straighter
and oblique above, and rounding into the hinge-margin. Lwunule apparently long,
lanceolate, excavate, bounded by a straight elevated line from the front of the
umbo to the anterior point. Contour of back convex, with a wide, well-marked,
subangular depression (running from the middle of the umbo straight and
obliquely to the centre of the inferior margin) from each side of which the contour
rises with a gentle convexity, being bounded laterally by the ridge of the lunule in
front, and sloping gradually to the margin behind. Surface covered by about eleven
or twelve large, low, rounded transverse ridges, which divaricate from the front,
are lost in the median constviction, become again prominent for a short distance,
and then vanish on the posterior part of the shell.
Size (of left valve).—Length 50 mm., height 33 mm., depth 11 mm.
Localities. —A fine specimen from Marwood is in the Museum of Practical
Geology ; M‘Coy’s type specimen and another small specimen from Marwood, and
a poor specimen from Top Orchard, are in the Woodwardian Museum ; another
from Roborough is in the Porter Collection.
Remarks.—This is evidently the species to which M‘Coy has given the name
L. constricta, when describing its right valve from three specimens from Marwood.*
He was inclined to think it the same as ‘‘the shell referred by Phillips (in the
‘ Pal. Foss.’) to the Silurian Cypricardia impressa of Sowerby,” and this, I think,
our two figured specimens prove undoubtedly to be the case.
Cypricardia ? impressa, Sowerby,’ itself is probably closely allied, but it seems to
be smoother and more transverse, and to have a smaller and more anterior umbo.
Affinities.—It appears to me that the present species is closely allied to the
German shell described by F. Romer as Myacites impressus,’ but specifically differs
1 1839, Sowerby, in Murchison’s ‘Sil. Syst.,’ p. 609, pl. v, fig. 3.
* 1844, F. Romer, ‘ Rhein. Uebergangsgeb.,’ p. 79, pl. ii, fig. 4.

in having a larger umbo, in being much less transverse, in being more produced
and angular on the anterior side, and in its concentric ridges fading rather more
rapidly behind (so as to leave a rather larger smooth postero-superior portion),
and also on the front side of the median depression.
Myacites striatulus, F. Rémer,' which is nearer in shape, has strong radiations.
Allorisma plicatella, Gihlert,? is very similar, except that it has no median
constriction, the concentric ribs being continuous over the whole back of the
shell. It thus shows the proximity of Leptodomus to Allorisma.
Grammysia constricta, Hall,’ which its author first described as Grammysia
(Leptodomus ?) constricta,* but without any reference to M‘Coy’s species, appears
to be a rather variable form, usually with considerably more numerous concentric
ridges, and of greater transverseness; the American specimens figured by Hall
being normally twice as long as high, while ours, though perhaps variable, seem
to be only half as long again as the height. If this means that the species are
distinct, the name of the American form should become Leptodomus Halli.
Grammysia Hannibalensis, Shumard,’ 2grees more nearly with our shell in
dimensions, but its umbo is more anterior and oblique, and its constriction seems
to range more backward.
Leptodomus Canadensis, Billings,’ is closely allied, only differmg in having a
much smaller umbo and in being longer.

apparently slightly concave in front, gently convex behind. Postero-inferior
margin very convex. Postero-superior margin oblique. Valve with a vertical
concave constriction very near the anterior side; and covered in with twenty or
thirty strong, elevated, regular undulations, which vanish rather suddenly before
reaching the posterior slope, and which are divaricated in the anterior constric-

tion so that their number is greatly reduced in front. Surface also ornamented
with finer minute radiations and concentric lines (fig. 24 a).
Size.—Length about 35 mm.
Localities—One specimen from Landlake is in the Museum of Practical
Geology ; one in the Barnstaple Museum from Sloly ; and two in the Woodwardian
Museum from 8.W. of Sloly.
Remarks.—The crushed and fragmentary or obscured state of these specimens
renders them very difficult to understand, but a comparison with Phillips’s figures
(the originals of which I have not seen) makes me believe that they are identical
with them, while the type of Sowerby’s Ludlow shell in the Museum of the Geological
Society, though considerably larger, so closely resembles them that I do not see
the way to separate them in the absence of more perfect specimens. As far as can
be seen they appear to belong to the genus Leptodomus, but are distinguished
from JL. constricta by the much more anterior position of the constriction, the
character of their ornament, their greater obliquity, and other points.
2. Genus—Sanournouites, M*Coy, 1844.
This genus was originally defined by M‘Coy, but made by himself and others
to include many shells which are not congeneric. It has since been restricted by
Hall, de Koninck, and Fischer.
1. Sancuinotites Porrsri, n. sp. Plate IX, figs. 2, 2a.
Description.—Shell of moderate size, suboval, convex, very transverse. Hinge-
lme very long, straight. Umbo very much flattened, incurved, depressed,
proximate, curving forward, extending slightly above the hinge-line, and situated
about one-fifth or one-sixth from the anterior end. Anterior margin subangular,
being concave above and convex below the angle. Inferior margin very wide,
gently and evenly convex. Postero-inferior point produced, bluntly angular.
Posterior margin short, straight, oblique. Keel, acute at first, then obscure,
running from behind the umbo to the postero-inferior point, and dividing the shell
into two portions, of which the postero-superior is obliquely concave and smooth,
and the anterior transversely convex, and covered by about forty very regular,
rounded, rather elevated, transverse ridges. Ridges divided by rather narrower
furrows, and seeming to diminish in size from the keel forwards, and only to amal-
gamate very close to the anterior margin. Signs of a narrow lunule.
Size.—Height 14 mm., length 34 mm., depth of one valve about 4 mm.
78 DEVONIAN FAUNA.
Locality.— One specimen in the Porter Collection in rubbly brown stone from
Pilton.
Kemarks.—This fossil is distinguished from 8S. mimus, n. sp., by the great
regularity, prominence, and number of its ribs. Thus it approaches Cardinia
Devonica, Geinitz,! but shows little sign of the lessening of the ribs on the marginal
parts or of any median depression, and is further distinguished by its stronger
keel and rounded base, and by the ribs being absent on the postero-superior region.
From Leptodomus constricta® it is distinguished by much more numerous ribs,
lower umbo, and the absence of a median constriction.
Sanguinolites angustatus, Phillips, sp.,° the type of the genus, is much more
transverse; and S. discors, M‘Coy,* (Fischer’s type), is very similar, but longer
and more rounded in front.
2. SANGUINOLITES MIMUS, n. sp. (MS. Museum of Practical Geology). Plate IX,
figs. 4, 6, 7?
Description.—Shell of medium size, transverse, convex, suboval. Umbo wide,
depressed, flattened, proximate, situate at the anterior fourth of the length.
Anterior side somewhat produced, flattened. Anterior margin obliquely convex
below. Inferior margin long, slightly convex. Posterior margin roundly convex.
Hinge-margin long, straight, slightly oblique. Contour of back vertically convex,
horizontally slightly convex, but becoming steeply concave in front of umbo, and
gently concave in the postero-superior slope. Postero-superior slope bounded by
a convexity or incipient keel from rear of umbo to postero-inferior point, which is
followed above by a linear concave depression running from beneath the umbo to
the upper part of the posterior margin, and above that by a rounded thickening of
the shell over the hinge-margin. Surface bearing about seventeen rather unequal
and irregular concentric rounded ridges, separated by rather wider concave
intervals and being smallest near the umbo, occasionally divaricating in front and
becoming suddenly faint and invisible on the postero-superior slope. Minor
ornamentation (at least on posterior parts) consisting of crowded microscopic
transverse lineations.
Size of left valve-—Height 16 mm., length 34 mm., depth 5 mm.
Localities.—In the Museum of Practical Geology is a specimen from Croyde ;

in the Barnstaple Athenzum one from Marwood, a cast and mould from Sloly,
and a large fragment of the posterior side from Sloly, which shows the minor
ornament; and in the Porter Collection two from Pilton.
Remarks.—One of the characteristics of this species seems the indistinct
double swelling of the posterior slope. Its rather prominent and irregular
ornament, which abruptly vanishes behind, seems another distinguishing feature.
Affinities —Pullastra complanata, Sow.,' as given by Phillips,’ differs by having
the inferior margin concave, the posterior ridge stronger, and the surface smoother.
Sowerby’s own shell is also more deltoidal.
Leptodomus senisulcata, Phillips, sp.,° approaches it in ornament, but is very
different in shape, being more convex, with a more anterior umbo and a dorsal
constriction.
Sanguinolaria lirata, Phillips,* though looking somewhat similar in Phillips’s
figure, is really totally different in shape, character, and ornament. It belongs to
the genus Ctenodonta.
Glossites Manitobensis, Whiteaves,’ simulates it in ornament, but is narrower,
and is more definitely flattened and smoothed behind.
Sanguinolites concentricus, Goldfuss,° or rather, Beushausen,’ sp., appears to
have stronger and more regular markings, which are continued over the posterior
slope, and also a smaller and lower umbo. It was described by Goldfuss* under
the name Sanguinolaria sulcata, Phillips,’ but the original S. sulcata is very
different, being wider behind, and without any posterior compression or truncation.
3. Genus—Epmonp1a, de Koninck, 1842.
Shell equivalve, oval or subcircular. Beaks central or anterior. Surface
with concentric striz, and sometimes obscure rays. Hinge narrow, edentulous.
Ligament external. Muscle-marks superficial. Pallial line simple.

Description.—Shell rather small, transversely oval, rather strongly convex.
Hinge-line unseen, but apparently about two-thirds the length. Anterior and
posterior margins roundly and evenly convex, slightly oblique. Inferior margin
long, slightly convex. Umbo apparently prominent, broad, rounded, and incurved,
situated at about the anterior fourth of the length. Lunule undefined.
Contour convex vertically, nearly flat transversely on the back, convex posteriorly.
Surface with about ten irregular undulations of growth, covered by numerous
finer lines, the ornament continuing strong on the posterior slope.
Size.—Length 19 mm., height 12 mm., depth of one valve 4 mm.
Localities—In the Barnstaple Atheneum is one example from Kingdon’s,
Shirwell, and one from Sloly; in the Museum of Practical Geology one from
Braunton, and one from West Angle Bay, Pembrokeshire; in the Porter
Collection one from Roborough.
femarks.—The species seems distinguished by its almost regularly oval shape,
slight transverseness, comparative smoothness, and the absence of any posterior
angle on the back.
Our figured specimen appears exactly similar to F. A. Romer’s figure of his
Cardinia Bodana, except that it is very slightly more transverse.
It also seems perfectly like H. Bui'lingtonensis, White and Whitfield, with
which Hall at first associated shells which he afterwards separated as H. subovata,
Hall, but which present so close a resemblance that it is hard to trace in his
various figures the slight differences which he points out.
Affinities.—E. unioniformis, Phillips, sp.,1 which is de Koninck’s type of the
genus, differs in being more circular.
Leptodomus semisulcata, Sowerby, sp., as given by Phillips,’ is more ovate,

and more swollen behind, and has more definite, divaricating ribs, and a distinct
anterior dorsal constriction.
Sanguinolites mimus is longer, more regularly and coarsely ribbed, and has a
definitely depressed posterior slope.
Sphenotus Hicksti, n. sp., is longer and less regularly oval, has a more
depressed back, a post-umbonal keel, and a depressed posterior slope.
2. Hpmonpia? ATHEN®,n. sp. Plate IX, fig. 3.
Description.—Shell very small, transversely oval, moderately convex. Umbo
small, low, proximate, situated at about the anterior third of the length. Anterior
margin apparently deeply convex. Inferior margin long, nearly straight.
Posterior margin deeply convex. Back transversely flattened. Surface with about
eight or ten strong, regular, elevated, rounded, concentric ridges, separated by
similar depressions.
Size.—Height 5 mm., length 8 mm.
Locality.—One specimen from Bradiford is in the Barnstaple Atheneum.
Remarks.—The only specimen of this shell that I know is very poor, but it seems
to be distinguished from accompanying species by its transverse oval form, and its
very strong, sharpish, regular striz. On the same slab are several specimens of
Cypricardinia scalaris, but it does not seem possible that it could have affinity
to that rather variable species.
It approaches in shape, and agrees in ornament with, several of the numerous
Carboniferous species referred by de Koninck to this genus.
It is so similar in general appearance to Sanguinolites Ungeri, F. A. Rémer,'
that for a long time I thought it belonged to that species ; but IF’. Rémer shows that
shell to be congeneric with his Venulites concentricus,’ and a Belgian specimen in the
Woodwardian Museum shows the latter species to be widely removed, and more
in the style of an Astarte. The shell given by Kayser® as Allorisma Ungeri,
F. A. Romer, sp., differs in having finer and much more numerous striations.

3. Epmonpia? Hamuineii, n. sp. Plate XI, fig. 3.
Description.—Shell large, transverse, sub-equilateral, very convex. Umbo
large, rounded, incurved, direct, extending above the hinge-line, and situated a
little in front of the centre. Anterior and posterior margins evenly and deeply
convex, the latter being the broader. Inferior margin long, gently convex.
Hinge-line shorter than the length of shell. Contour of back evenly convex.
Surface covered with very numerous, fine, irregular growth-lines,
Size.—Height 23 mm., length 32 mm., depth of valve about 10 mm.
Localityx—One specimen is in Mr. Hamling’s Collection, in a pebble from
the beach at Saunton Point.
Remarks.—The umbo and hinge of this fine specimen are obscured by the hard
gritty matrix, and it is impossible to decide its exact generic position. It appears
far removed from any of the other species of our beds, being marked by its
remarkably regular, convex, oval form, and the central position of its umbo. As
it bears most general resemblance to some species of Hdmondia described by
de Koninck, it seems best to refer it provisionally to that genus. In the same
pebble, specimens of Strophalosia productoides, Athyris concentrica, and Orthis
imterlineata occur.
Affinities—It seems to have a larger umbo than HL. orbitosa, de Ryckholt'
and H. prelata, de Roninck.’
4. Genus—Sruenotvs, Hall, 1885.
Shell equivalve, very unequilateral, elongate, sub-trapezoidal. Anterior end
short. Posterior end obliquely truncate. Beaks sub-anterior. Hinge-line long,
nearly straight. Umbonal ridge defined. Postero-superior slope marked
characteristically with a median ridge. Back with a broad median depression,
sometimes producing a constriction inthe margin. Surface concentrically striated.
Hinge narrow, with two short narrow central teeth in right valve, and two extremely
slender lateral teeth. Ligamental groove slender, external. Anterior muscle-scar
strong, marginal. Posterior scar shallow. Pallial line simple.
The above description is condensed from Hall, who states that the genus
differs from Sanguinolites and Allorisma by its umbonal and post-cardinal ridges,
its trapezoidal shape, its central cincture, and the character of the hinge.
Judging by the external characters, the following species appear referable to it.

1841. PuntastRa? compnianata, Phillips (not Sowerby). Pal. Foss., p. 35,
pl. xvii, fig. 56.
Description.—Shell rather small, convex, transverse, subquadrate. Hinge-
margin with two long, transverse, lateral teeth. Umbo prominent, wide, flattened,
incurved, anteriorly truncate, situated at about the anterior third of the length.
Anterior margin rather broad, deeply convex. Inferior margin long, straight, or
very slightly concave. Postero-inferior corner much produced, roundly convex.
Posterior margin probably oblique. Contour of back vertically convex, trans-
versely flattened and slightly depressed in the middle; curving rapidly in front
to form an undefined lunule, which is bisected by the produced margins; bounded
behind by a more or less distinct rounded angle or ridge from the umbo to the
postero-inferior corner. Posterior slope obliquely flattened. Surface with ten or
fifteen irregular undulations, less marked on the sides, and with a minor ornament
of minute, crowded, sharpish transverse lines, only seen where the shell is well
preserved. Shell-structure thin.
Size-—Lenegth 25 mm., height 13 mm., depth of valve 5 mm.
Localities—In the Museum of Practical Geology is a specimen from the new
Ilfracombe Road near Barnstaple; in the Barnstaple Atheneum, eight from
Kingdon’s, Shirwell; and in the Porter Collection two from Pilton.
Remarks.—While these fossils clearly belong to the species described by
Phillips as Pullastra complanata, Sowerby, they are perfectly distinct from Sowerby’s
own species.’ he latter is a much more oblique and trigonal shell, with a very
narrow anterior end, and altogether has a more mytiloid appearance, as seen by
his type in the Museum of the Geological Society.
None of our specimens are very perfect, or give the full shape. The amount
of depression in the back and of the transverseness seems to vary considerably.
One of Mr. Porter’s specimens is a cast, and seems to show two long posterior
teeth. This is not, however, very clear.

84 DEVONIAN FAUNA.
Description.—Shell obliquely convex, very transverse, of moderate size. Umbo
situated at about the anterior third of the length, small, much flattened and
truncated, incurved, tending forward. Hinge-line probably nearly the length of
the shell. Anterior margin produced, narrow, evenly convex. Inferior margin
very long, nearly straight, slightly oblique. Posterior margin broad, gently
convex. Contour of back gently convex on the line of greatest depth from umbo
to postero-inferior corner, in front of which it is obliquely flat, and behind which
it is gently convex. Surface with afew rather irregular and divaricating, rounded
growth-ridges on the back, which almost vanish on and behind the aforesaid line.
Size.—Height 10 mm., length 24 mm.
Locality.—There are three specimens from “the top of the Baggy Stage,” S.W.
of Sloly, in the Woodwardian Museum.
Remarks.—These shells are very indistinct, but they appear so closely to
correspond with the figures given by Hall of his Sphenotus solenoides, that there
seems great probability that theyare identical. Our best preserved specimen (fig. 10)
appears still more transverse, but this is evidently due to the squeezing to which
the beds have been so much subjected, and possibly the greater flattening and
depression of its umbo may be due to the same cause. The posterior ridge or keel
seems sharper in the American shell, and the inferior margin sometimes slightly
concave.

Description.—Shell (cast) rather large, extremely transverse, subconvex,
quadrate. Umbo flattened, adpressed, proximate, curved forward, and situated at
about the anterior tenth of the length. Hinge-line straight, about five-sixths the
length of shell. Anterior margin probably sloping obliquely from umbo to the
anterior angle, which is one-third way down, and then becoming obliquely convex.
Inferior margin very long, direct, straight. Postero-inferior corner rather pro-
duced, apparently deeply convex. Posterior margin very short, slightly convex
and oblique. Contour of back rounded in front, slightly concave beneath umbo,
and with a blunt keel running from behind umbo in a slight curve to postero-
inferior corner. Posterior slope flat and oblique, and marked with a few strong
PHTHONIA. 85
unequal growth-ridges. Anterior muscle-scar apparently large, and occupying the
anterior corner. Posterior muscle-scar large, circular, and indistinct, and situated
below the end of hinge-line on the posterior slope. Escutcheon very long,
narrow, and apparently concave and defined.
Size.—Height 16 mm., length 52 mm., depth of the closed shell 12 mm.
Locality.—There is a specimen in the Mantell Collection in the British Museum
without a locality, but resembling in the mineral character the fossils of the
Marwood Cucullea beds.
Remarks.—The only specimen of this shell, though very remarkable in form,
is so badly preserved that it is very. difficult to say what itis. The hind margin
is gaping, but the front is so much worn away thatits true shape isdoubtful. It
appears to me very closely to resemble the figure which Beushausen gives in the
text of his latest work as the undistorted form of Goldfuss’s Sanguwinolaria
soleniformis. ‘This, as far as can be judged, chiefly differs from ours in being
slightly shorter, and slightly less concave in the post-umbonal slope, and in having
a rather longer front margin; differences probably due to the German fossil
having the shell. Whether Beushausen is right in identifying his shell with
Goldfuss’s, which is totally different in appearance, I have no means of judging, but
if he is, it seems clear that our fossil may also be referred to it.
Beushausen places his shell under Sphenotus, with which it appears agreeable
except in its extreme length. Our specimen has so much the appearance of
straight-hinged species of Hall’s genus Cimitaria (regarded by Beushausen as a
synonym of Leptodomus, to which it is at all events allied), that it is quite
possible it may prove to belong to it, but that cannot be ascertained till a specimen
showing the true shape of its front side be found.

Description.—Shell small, convex, extremely transverse (umbo and anterior
parts unknown). Upper and inferior margins very long, straight, and nearly
parallel. Posterior margin roundly and evenly convex. Contour of back straight
horizontally, roundly convex vertically. Surface with a few unequal, indistinct,
transverse strie.
Size.—Length more than 17 mm., height 6 mm., depth of valve 2 mm.
86 DEVONIAN FAUNA.
Localities—A single specimen from Top Orchard is in the Barnstaple
Athenzeum, its mould being in the Porter Collection.
Remarks.—Though this specimen is so imperfect that its full shape, &c., cannot
be ascertained, I have figured it, as it does not seem at all in accord with any of
our other fossils. Its extreme elongation and the uniformity of its contour is
remarkable, even if partially induced, as is indicated by a specimen of Orthis
interlineata, Sow., on the same slab being slightly distorted in the same direction.
The nearest approach to it is the shell recently described by Dr. Kayser, from
Belgium, under the name Phthonia, ef. cylindrica, Hall,’ which is so like that it may
perhaps prove identical. From Hall’s own species the differences are greater.
A fragmentary shell, from South Petherwyn, in the Museum of Practical Geology
has nearly the same dimensions, but differs so much in detail as evidently to be
distinct.
III. Family—Proruyripa, 8. A. Miller, 1889.
1. Genus—Protuyris, Meek, 1869.
Shell equivalve, very inequilateral and transverse, moderately convex, con-
centrically striated, gaping and rectangularly notched in front, close or slightly
gaping behind ; umbo depressed, subterminal, with a small (elevated) fold running
from it to the anterior notch ; inferior margin direct, convex or re-curved.
There seems one discrepancy between the genus as generally defined, and the
characters shown by English species, viz. that the notch in the latter is the term1-
nation of an elevated ridge running from the umbo, and not of a groove, as appears
indicated by Meek, Hall, Zittel, Fischer, &c. Whether this points to a real
difference I cannot say, but the character of the ridge in the English shells is clear.
The species appear to be gregarious.

Hinge-margin long (details unknown). Anterior margin broad, roundly convex,
with a small triangular notch or nick at its centre. Inferior margin long, very
slightly convex. Postero-inferior corner produced, narrow, very convex.
Posterior margin nearly straight, very oblique. Surface with unequal, low,

convex growth-swellings, separated by deep impressed lines, and apparently
covered with finer lineations, and with one or two impressed rays on the postero-
superior slope. Contour flattish on the back, steeply convex on the supero-
posterior part, where a narrow groove runs from the rear of the umbo to the
margin, and broken in front by an arching ridge running from before the umbo to the
anterior marginal nick, and defining a lunule. Shell-structure massive. Pallial
line at some distance from the margin. Posterior muscle-scar apparently small,
and situated near the posterior point. Anterior muscle-scar near the umbo.
Interior of the shell with grooves and pits.
Size.—Height 12 mm., length 18 mm., depth of one valve about 3 mm.
Localities.—There are twenty-six specimens in the Museum of Practical
Geology from Baggy Point, “ South Cave,” and “ just over the grits”’ in blackish
Limestone.
Remarks.—Though these shells were evidently common in their locality, it has
been difficult to find sufficiently perfect specimens to define the species, especially
as it seems to have been rather variable in shape.
Affinities.—It differs from Prothyris contorta in being shorter and less oblique,
and in haying a convex base.
2. PROTHYRIS conTorTA, n. sp. Plate IX, figs. 15, 16, 16a.
Description.—Shell small, convex, subquadrate, very transverse. Hinge-line
unseen, but apparently about half the length of the shell. Umbo small, low,
oblique, flattened, and situate near the anterior end. Anterior margin very
convex, but broken at about its centre by a small, deep, concave notch, which is
the termination of a rounded elevated conical ridge, running to it from the front
of the umbo. Inferior margin very long, convex in front, straight or even
slightly concave in the median region, becoming convex behind. Postero-
inferior corner produced and very deeply convex. Posterior margin oblique
above. Contour of back very evenly convex except for the tubular ridge. Cast
marked with one or two deep linear furrows running along the postero-superior
edge, and with a triangular perpendicular clavicular groove under the umbo.
Muscle-marks apparently large and not marginal. Pallial smus apparently deeply
indented. Surface covered with very numerous microscopic, impressed, con-
centric strie, and having five or six fine sharp sub-parallel ridges running along
the postero-superior side of the shell immediately below the hinge-margin. Shell-
structure rather thick for the size of the shell.

Locality.—There are several small specimens in the Barnstaple Athenaeum
from Kingdon’s, Shirwell, and two or three in the Porter Collection from Pilton.
Remarks.—While in many respects good, the specimens leave much that is
doubtful about this species. It seems to be distinguished by its very long subquad-
rate or rhomboidal shape and slightly sigmoid inferior margin.
3. PROTHYRIS SCALPRATA, n. sp. Plate IX, figs. 17, 18, 18a; and (?) Plate X,
figs. 16—17 a.
Description.—Shell small, equivalve, gently convex, lancet-shaped, very
transverse. Umbo wide, low, proximate, slightly rounded, very oblique, arching
forward, concavely truncate in front. Anterior margin produced, broad, very
convex, but suddenly and deeply notched at the medio-anterior point, below which
it immediately curves with a slight convexity into the inferior margin. Inferior
margin very long, and gently and evenly convex. Posterior side long and narrow.
Posterior margin produced to an almost sharp median angle, with similar gently
convex sides ; the upper side becoming slightly concave as it meets the end of the
hinge-margin rather behind the middle line of the shell. Hinge-margin straight,
about half the length of the shell. Hinge with three or four long, linear, parallel
(or radiating), transverse, posterior lateral teeth. Lunule deep, ovate, defined by
a raised tubular ridge, which arches from the umbo to the notch in the anterior
margin. Contour of back vertically gently convex, horizontally nearly flat,
obliquely truncated in the extreme supero-posterior part, concave in the antero-
superior part or lunule, and broken by the squarish conical arching ridge running
from the front of the umbo to the anterior notch. Surface ornamented with
distant impressed striz or growth-lines, especially near the margins, and with two
or three slight sunken radiating threads on the postero-superior part of the shell.
Size.—Length 16 mm., height 7 mm., depth 3 mm.
Localities.—There is a specimen (of the open valves) from Croyde, and another
from the Sloly beds of Plaistow Mill Quarry, near Barnstaple, in the Museum of
Practical Geology; there are numerous specimens from Sloly in the Barnstaple
Athenzum, from 8.W. of Sloly in the Woodwardian Museum, and from the Sloly
Quarry in my Collection.
Remarks.—This species, though rarely found in at all good preservation, is
evidently an abundant and characteristic fossil of the Sloly beds. In the Sloly
Quarry Dr. Hicks and I observed a bed near the Lingula squamiformis bed which
SCALDIA. 89
is absolutely covered with their crowded valves, though so decayed and often so
distorted that they cannot be individually recognised, and it is only by means of
an occasionally better preserved specimen that the species can be made out. The
totally different appearance sometimes produced by the extreme distortion is
illustrated by the two figures on Pl. X, which were not recognised as the present
species till long after they were drawn.
Affinities.—From the two accompanying species of this genus the present shell
is at once distinguished by its long lancet-like shape and its angular posterior side.
It appears confined to the Sloly beds, while the other two occur higher in the
series, the one near the base, and the other in the middle of the Pilton beds.
It is something like Ctenodonta tumida, Sandberger,’ in general shape, but is
totally different in detail.

1. Genus—Scatpta, de Ryckholt, 1847.
I have placed the following species under this genus as being possibly in accord
with it, but sufficient is not known of the shell to determine its true affinities.
1. Scaupia? LonGa, n. sp. Plate X, figs. 1, la, 2.
Description.—Shell small, transversely oval, very convex. Umbo nearly central,
prominent, slightly arching forward. Anterior and posterior margins nearly
similar and approximately semicircular. Inferior margin gently convex. Contour
rather flat transversely, very convex vertically, becoming concave in the superior
corners. Umbonal slopes rounded. Muscle-scars extremely large, irregularly
subcircular, situated on the superior side not far from the umbo. Shell-structure
very thick.
Size.—A single valve is about 12 mm. long, 9 mm. high, 3 mm. deep.
Locality.—T wo specimens are in the Museum of Practical Geology from South
Cave, Bagey Point.
Remarks.—The nearly central umbones and sub-equilateral transversely oval
form distinguish these little shells from any that otherwise approach them.

They are evidently casts of a very thick shell, and show traces of a few
transverse ridges of growth. In the neighbourhood of the umbo are a few
prominences, indicating indented pits in the inner surface of the valve. The
muscle-scars seem rounded and unusually and equally large; the anterior scar
is situated halfway from the apex to the centre of the anterior margin, and
the posterior scar much nearer to the centre of the posterior side.

Localities—In the Barnstaple Athenzeum are two specimens on a slab from
Bradiford and one from Top Orchard; in the Porter Collection two from Pilton;
and in my Collection six from the lane between Wrafton and Heanton.
Remarks.—After comparing these with specimens from Lummaton I feel no
doubt that they belong to Phillips’s species. As their surface is often much
decayed, their markings are not always so definite, but their character seems the
same, and their shape varies within the same limits. They seem still smaller in
size.
I much regret that I am unable to follow Beushausen in separating the three
species quoted above from his recent masterly work. Even if the distinctions
which the learned German draws are permanent in the Continental specimens, it
appears to me that they are unlikely to indicate more than local varieties. As far
as I can see, English specimens might be selected which would be ranked in each
of them. It would seem that it is not always the same valve which is the largest
inthe English species, and that the median constriction varies much in its strength,
CYPRICARDINIA. 91
C. impressa, Pacht, appears to agree in form and ribbing, but is of a much
larger size.
2. CYPRICARDINIA Psp. Plate IX, fig. 22.
Description.—Shell small, oblique, transverse. Anterior side much contracted,
possibly subangular. Antero-inferior margin rather long, oblique. Inferior
margin moderately short, very slightly convex. Postero-inferior corner rounded,
very convex. Hinge-margin about three-quarters (?) of the length. Umbo
broad, flat, prominent, curving forward, and situate anteriorly. Contour of back
flattened horizontally between lines of curvature which run from the umbo to the
lower part of the sides. Surface covered by about twenty large, broad, low, sub-
angular, concentric ridges, apparently marked with minute crenulations.
Size.—13 mm. long, 9 mm. wide.
Localities.—A specimen from Sloly is in the Barnstaple Athenzum.
Remarks.—This specimen is very obscure. It has every appearance of
belonging to the genus Cypricardima, though there seems no positive evidence
that it does so.
3. CYPRICARDINIA, Sp.
Description.—Shell minute, suborbicular, very convex, oblique. Umbo elevated,
prominent, incurved, direct, anterior. Anterior margin narrow, apparently
nearly straight. Inferior margin oblique, slightly convex. Postero-inferior
corner subangular, produced. Posterior margin long, oblique, shghtly convex.
(Hinge-margin unseen, perhaps half the length of shell.) Lunule apparently deep
and undefined. Contour very convex, divided by a blunt angle from umbo to
postero-inferior corner, behind which it is flatter and steeper. Surface covered
with numerous strong parallel ridges on the back.
Size.—About 2 mm. long, 1°5 mm. high, and °5 deep.
Locality —A single specimen from Marwood is in the Barnstaple Athenzeum.
Remarks.—This tiny shell seemed too indistinct for figuring, but by a minute
examination many of its details have become evident. It reminds one strongly of
the general form of Opis, but no doubt is really a species of Cypricardinia. 7
Affinities.—It differs from C. scalaris by its shortness, convexity, and much
finer striation, in the last point coming nearer the species last described.

Description.—Cast moderate in size, almond-shaped, transverse. Umbo rounded,
inclined slightly forward, situated behind the anterior third. Hinge-line long,
large, gently convex. Hinge-teeth large, broad, oblique. Anterior margin broad,
very convex. Inferior margin long, slightly convex. Posterior corner produced,
narrow, subangular. Postero-superior margin long, oblique. Contour of back
convex, becoming steeper in front, obliquely flattened in the postero-superior part,
sometimes with two indistinct rounded angles on the cast, which radiate to the
infero-posterior region. Anterior muscle-scar large, angular, deep, situated
near the umbo; posterior scar more elongate and less distinct. Shell massive.
Size.— Height 19 mm., length 26 mm., depth of one valve 9 mm.

county Cork, and five poor and doubtful specimens in the Woodwardian Museum
from west of Saunton Court.

MYOPHORIA. 93
Remarks.—It is very doubtful whether this shell should be included in our
list, the five Devonshire specimens being so poor as to be almost undecipherable.
The shells figured appear to belong to the Infra-carboniferous of Ireland.
Keferstein united Tellina or Cardinia inflata, F. A. Romer, with C. trapezoidalis,
F. A. Rémer. These Beushausen in 1884 again separated into three species,
calling Keferstein’s Sch. inflatus by the name Sch. Kefersteini. It appears to me
that Beushausen’s figure of Sch. Kefersteini is almost exactly like Romer’s figure of
C. trapezoidalis and Rémer’s first figure of 7. inflata, while his figure of Sch. inflata
seems more like Romer’s second figure and Keferstein’s. To the latter of these
one of our specimens is very similar ; and a second, which is not figured, equally
resembles the former. Our own material was insufficient to prove anything, but
as other species of the genus are evidently liable to much variation, I was led to
the conclusion that the balance of probability was on the side of Keferstein’s view.
It is interesting, therefore, to find that in his later work Beushausen has reversed
his former judgment, and reunited all three as M. inflata, though at the same
time adding another form, which seems to me also to be identical.
Azinus nuculoides, M‘Coy, though much smaller, may perhaps be the young or
a dwarfed variety of the same species.

Description.—Shell moderate in size, convex, slightly transverse, subquadrate.
Umbo small, direct, incurved, slightly truncate behind, and situate rather in front
of the centre. Hinge-margin short, convex. Hinge containing a large, triangular
central tooth, and a smaller, more elongate, and indistinct posterior tooth.
Anterior margin broad and roundly convex. Inferior margin rather long, slightly
convex. Postero-inferior corner rather produced and subangular. Posterior
margin oblique and slightly convex. Contour of back divided by a blunt angle
running from the umbo to the postero-inferior point, in front of which it is trans-
versely flat, becoming convex in front, and behind which it is oblique and flat.
Posterior muscle-scar high up near the centre of the posterior hinge-margin.
Size.—Height 16 mm., length 20 mm., depth of one valve 5 mm.
Localities—In the Museum of Practical Geology are two specimens from
Marwood, six from Shirwell, one from Petherwyn, and one from West Angle
Bay, Pembrokeshire. In the Porter Collection is one from Marwood; in the
Woodwardian one from Marwood and two very obscure specimens from Baggy
Point.
Remarks.—The Petherwyn specimen almost exactly agrees with Phillips’s
figure, the only difference being that it is perhaps slightly more transverse.
Being in the Museum which contains so many of his figured specimens, it is
probable that it is the original type of his Oypricardia deltoidea, and it is to be
observed that Phillips noted its resemblance to Avinus.
M‘Coy states it to be not uncommon in the sandstones of Baggy Point, and it
seems probablethat the beds to which he refers are those which have contributed eight
specimens from Shirwell and Marwood to the same museum. ‘The first question,
therefore, is whether these specimens can be identified with the type. They differ at
first sight in being flatter and in having a less prominent umbo, above which the
hinge is seen, whereas it is invisible in the type specimen. At this point Mr.
Porter’s specimen may be noted as uniting them in shape, and partially showing the
teeth. These Marwood specimens are, indeed, of all shapes, long and high, but this
is probably largely due to fossilisation, or at least to similar causes to that which
produced such variations in the specimens of Cucullea and Avicula of the same
MYOPHORIA. 95
beds. It is also to be observed that one of them so exactly resembles Curtonotus
elegans, Salter, as to render it very probable that it is only a variety of the same
species.
We next come to some American forms which are strikingly lke our sup-
posed type-specimen, but which appear generally to differ from our fossils by having
more elevated umbones. This seems probably to be due to the American fossils
retaining their shells, while our specimens are all in the nature of casts.
Schizodus quadrangularis, Hall, and Sch. Chemungensis, Conrad, appear
identical with each other and with the present shell, except that they are about
half as large again—a fact which could hardly give them more than varietal rank,
as both the English and American shells vary considerably in size. Schizodus
adpressus, Conrad, is regarded by Hall as ‘‘ probably only a variety of Sch.
Chemungensis which lived under different conditions.” Sch. xqualis, Hall, is
separated by him from Sch. Chemungensis, var. quadrangularis, as having ‘the
base more broadly rounded and the anterior portion more expanded below ;”’
but, if he be correct in making the latter form a variety of Sch. Chemungensis,
it is difficult to see why the former also should not be included in it, and that
form is approached by the specimen from West Angle. As given by Whiteaves,'
however, Sch. Chemuwingensis is wider and more rounded.
On the whole there seems reason for regarding these various forms as not
more than varieties of one variable species.
Schizodus rhombeus, Hall, may also possibly be a variety; but, though
equalling the English shells in size, it seems essentially to differ from the adjacent
forms in being longer, and in having less anterior inflation.
Awinus orbicularis, M‘Coy, has much the appearance of being the young or
dwarfed form.
Affinities. —C. centralis, Salter,” seems distinguishable by its larger and more
terminal muscle-scars, its more central umbo, and its more oval form, without
signs of posterior truncation.
Schizodus obrotundatus, Beushausen,* appears to have a slightly larger hinge,
and not to be flattened and angulated on the posterior side.
Axinus obliquus, M‘Coy,* seems to have a much less inflated anterior side.

Description.—Shell rather large, equivalved, higher than long, subovate.
Umbo nearly central, prominent. Hinge large, much curved, with a large
triangular central tooth in the left valve fitted between two large teeth in the right
valve. Anterior margin long, moderately convex. Inferior margin short,
oblique, with nearly semicircular outline. Posterior margin similar to
anterior, but longer, and elbowed one-third way down. Contour gently and
nearly evenly convex, the greatest depth being not far from umbo. Pallial line
simple, some distance from margins. Anterior muscle-scar small, subcircular,
situate near the umbo. Posterior muscle-scar larger, situated rather above the
centre of the posterior margin. Interior of shell with a long, narrow, arching,
convex callosity, running from behind the umbo to the front of the posterior
muscle-scar. Surface apparently bearing a few growth-lines and numerous
indistinct concentric striz. Shell-structure very massive.
Size.—A cast of the closed valves measures 14 mm. long by 18 mm. high, and
9mm. deep. A large specimen is 32 mm. high by 23 mm. long.
Localities—In the Museum of Practical Geology are two specimens from
Richard’s Summer-house, Croyde Bay, three from Baggy, and one from
“Barnstaple Road ;” in the Woodwardian Museum a specimen from Barnstaple,
and three poor specimens from west of Saunton Court; and in the Porter
Collection two specimens on one slab from Pilton.
Remarks.—These specimens, though generally poor and often squeezed com-
pletely out of shape, appear to indicate a well-characterised species, distinguished
by its narrow ovoid form, short arching hinge, large teeth, small obliquity, and
massive shell, and by the long spoon-like callosity. The best Woodwardian
specimen, which is a double cast, displays the clasping of the teeth in such a
way as to show that they were very large and strong ; and, as it appears to retain
its true shape, it shows that the shell was sometimes considerably higher than
NUCULA. 97
long. In the Porter Collection, however, are two specimens which seem to be
specifically identical, and which show that its outline was sometimes more circular,
and in the young form more transverse and trigonal. Comparing these Devon-
shire specimens with Curtonotus unio, Salter,’ which occurs in profusion at
West Angle Bay, Pembrokeshire, it appears that they are closely allied, and
possibly only varieties of the same species. My Pembrokeshire specimens
are unfortunately all defective, it being impossible to extricate them from the
hard, crystalline, purple limestone in which they are embedded, but they appear to
be very similar in shape, except that they are usually more transverse and
quadrate than the Devonshire specimens. It is, however, clear that they
themselves varied very considerably in relative measurements.
Turning next to foreign specimens, we find that Keferstein’s figure of Schizodus
trigonus exactly agrees with our Woodwardian specimen, except that it is not quite
so high. This shell he identifies with Thetis (?) trigona, F. A. Romer, which is
smaller, and much more transverse and trigonal, and appears exceedingly like the
smaller of Mr. Porter’s two specimens. If this identification by Keferstein is
correct, there seems no reason against regarding all the above-mentioned English
shells as equally belonging to the same species.
Affinities.—Schizodus ovalis, Keferstein,’ differs in being more perfectly oval;
and, according to Beushausen,’ it has strong concentric striz.
Curtonotus elongatus, Salter,* is a very high form. Not having seen any
specimens of it, I am not certain whether his figures represent undistorted shells,
but, if so, they appear specifically distinct in outline, being long and straight
behind the umbo and deeply convex below.

Description.—Shell small, subtriangular, oblique, very convex. Umbo large,
prominent, elevated, rounded, situated at or about the posterior third of the length,
and tending somewhat backward. MHinge-line convex, about half the length of
the shell, and ending abruptly at the sides, bearing a fossette and a few very
minute teeth under the umbo, about four large, high, perpendicular, parallel, pos-
terior lateral teeth, and about six still larger and loftier, perpendicular, parallel,
anterior lateral teeth. Anterior margin much produced, straight and oblique
above, and deeply convex round the anterior corner. Inferior margin long,
gently convex. Posterior margin broad, roundly convex. Surface with ten or
or twelve fine, sharp, elevated, very distant concentric ridges, between which
several very fine intermediate concentric striz are seen. Shell-structure very
thick.
Size—Height 5 mm., length 9 mm., depth of both valves 3 mm.
Localities.—-In the Barnstaple Athenzum is a specimen from Upcott, and
another from Brushford ; in the Museum of Practical Geology one from Saunton,
and another (which is very poor) from east of Ashford Inn; in the Woodwardian
Museum three from west of Saunton Court ; and in my collection one from Upcott
Arch Quarry. Phillips records it from * Baggy Point.”
Remarks.—From Phillips’s description the species varied considerably in length,
size, and sculpture. The variation in contour is seen in our specimens, which
seem as arule rather more transverse than his. Our specimens are, with one
exception, casts. Itseems doubtful whether the possible crenulation of the striz
mentioned by Phillips is not simply due to fracture. In casts of the double shell
the impress of the lofty interlocked teeth leave a beautiful scalloped pattern, and
the margins protrude sharply at the ends of the hinge-line.

of a postero-superior depression, and the subrostrated shape, which is after the
manner of Leda. On the other hand, Beushausen points out that the type species
of Ctenodonta had a depression behind; and on the whole it is probable that
Palzxoneilo, and (Beushausen adds) Kenenia, should not be counted as more than
groups or sub-genera of Ctlenodonta. |

pt. 17, p. 78, pl. v, fig. 23.
Description.—Cast small, transversely ovate, sub-equilateral. Umbo small,
depressed, slightly recurved, and situated somewhat in front of the centre.
Hinge-line gently bent, about two-thirds of the length, and bearing five or six very
minute perpendicular teeth, uninterrupted by a fossette, under the umbo, five or six
large, parallel, perpendicular anterior teeth, and about twelve large, lofty, parallel,
perpendicular posterior teeth. Posterior side broad, much produced, with a deeply
convex margin. Inferior margin very long, gently convex. Anterior side broader,
with a more evenly convex margin. Surface covered by very numerous, regular,
minute, distant, concentric striz. Contour of back gently convex, steeper in front
than behind.
Size.—Height 9 mm., length 12 mm., depth of the cast of one valve 2 mm.
Localities.—In the Barnstaple Museum are two specimens from Fremington ;
and in my Collection two from Frankmarsh, and a fragment from Ironpost.
Remarks.—These shells seem to agree in shape and ornament with the imper-
fect valve which Beushausen figures from the Upper Coblenzian of Sechelden.
Though our specimens are chiefly casts, evidence of the nature of the ornament
is obtainable.
The species is named after R. B. Newton, F.G.8., whom I have to thank for
kind assistance.
Affinities. —Nucula fornicata, Goldfuss,' is similarly marked, but is larger and
deeper, and has a loftier and more lateral umbo and a fossette.
N. lineata, Phillips, is more convex and oblique, and has a much coarser
ornamentation.
It appears to be sometimes approached by the very variable N. domina,
Barrande,” which seems similarly ornamented.

vi, pt. 1, p. 79, pl. iui, fig. 13.
Description.—Shell rather small, suboval, convex, transverse, nearly twice as
long as high. Umbo small, low, proximate, rather sharp, without a clavicular
process, curving somewhat forward, and situated at or about the anterior third of
the length. Anterior margin broad, very convex. Inferior margin long, gently
convex, indented behind. Posterior margin very narrow and convex. Hinge-
line nearly as long as the shell, slightly bent at the umbo, nearly straight, bearing
in front of the umbo about ten small, short, obliquely vertical teeth which increase
in size anteriorly, and in rear of the umbo more than thirty-seven still smaller
teeth which increase in size posteriorly. Surface covered by twenty or thirty very
distant, sharp, erect, very elevated threads, between which several minute minor
striz# are sometimes apparent, and which are usually regular over the whole valve,
but fold into each other as they curve in on the hinge-margin. Contour convex, but
with a broad and shallow concave depression, between two slight convex radiating
swellings, running from the rear of the umbo to the posterior end of the inferior
margin. Lunule deep, ovate, undefined. Shell-structure thin. Muscular scars
large, oval, situate respectively at the anterior point, and just under the posterior
end of the hinge-line. Pallial line simple, rather distant from the margin.
Size.—A large valve from Saunton measures 29 mm. in length, 19 mm. in height,
and 6 mm. in depth.
Localities—In the Barnstaple Athenzeum are two specimens from Saunton,
four from Bradiford, two from Croyde Bay, and one from Top Orchard. In the
Woodwardian Museum are two poor specimens from west of Saunton Court. In
the Museum of Practical Geology are Phillips’s type specimen of the species from
1 1841, Phillips, ‘ Pal. Foss.,’ p. 38, pl. xviii, figs. 63 a, b.
CTENODONTA. 101
Pilton, another specimen figured by Phillips as Pullastra antiqua, Sow., from
Barnstaple, another from Croyde, a specimen of the valves in contact from ‘‘ North
Devon,” and one showing the hinge from Baggy. Inthe Porter Collection are two
specimens from Pilton. In my Collection are specimens from Saunton Hotel, from
the Laticosta Beds of Baggy, from Kingdon’s, Shirwell, and from Pouch Bridge.
Remarks.—This species is evidently one of the commoner and more widely
spread bivalves of these beds, though, probably from its tenuity, the specimens are
almost always defective or distorted. Hxamples of the extent to which this may
go are to be seen from Pl. XIII, figs. 1 and 3, the transverseness of which is, I
believe, entirely due to artificial elongation. The same causes also often more or
less obscure the posterior depression, which seems one of the most distinctive
features of the species. Under these circumstances it is extremely difficult to be
certain that it is more than a variety of Ct. antiqua, or to define the distinguishing
points if they really exist. After an examination, however, of numerous specimens,
including the originals of Sowerby’s and Phillip’s figures, I am inclined to the
opinion (1) that the two are probably distinct; (2) that they both belong to
Palzoneilo ; (3) that Sowerby’s Ct. antiqua is to be recognised by its more evenly
ovoid form, by its concentric ribs being smaller and more numerous, and by the
depression on the posterior region being smaller, weaker, and not so greatly
deflecting the margin; (4) that the present shell seems to be characteristic of the
Pilton beds proper, while Ct. antiqua appears to belong to the Marwood beds;
and, lastly, that the specimen Phillips figured as Ct. antiqua, Sowerby, sp.,
really belongs to Ct. livata and not to Ct. antiqua, as it shows the same
characters, especially the posterior depression, and is a Pilton, not a Marwood fossil.
The surface of some of the specimens is very well preserved, and shows four
or five concentric ridges between each of the major ribs. My impression is that
this may be another distinguishing mark where the fossil is sufficiently well
preserved to retain it. A cast in my collection from Kingdon’s shows that the
interior of the shell under the umbo is a good deal pitted, but had no internal
sulcus like that belonging to the kindred genus Nuculites. The specimens from
the Laticosta Beds show much variation in the number and regularity of the ribs.
Affinities—Palxoneilo Rauliniana, Rouault,’ appears to differ only in having
more numerous and irregular striations.
The type species of Palzoneilo, P. constricta, Conrad,” has much finer strie than
either of the Devonshire species, and is more acute behind. P. filosa, Conrad,’
which approaches nearer in ornament, appears to be more angulated, and its
strize are more lamellar, and its posterior depression broader and flatter.

Beushausen has described several species of Palzoneilo from the Spirifer-sand-
stein of the Oberharz, but being for the most part casts they are not easy to
compare ; P. brevis, Beushausen,' looks exceedingly like our specimens.
Ctenodonta wnioniformis, Sandberger,’ as given by Beushausen,* seems to
approach nearly, but it is larger and more unevenly ornamented, while Ct. gibbosa,
Goldfuss,* not Sow., sp., as given by him, seems also to be a shorter shell. I
should not, however, be surprised if they both prove to be varieties of the present
species.

Description.—Shell rather small, transversely ovate, moderately convex.
Umbo small, proximate, rather prominent, incurved, tending forwards, and situated
at the anterior third of the length. Hinge-margin long, straight posteriorly.
Anterior margin deeply convex or subangular. Inferior margin long, gently
and evenly convex. Posterior margin convex, rather broad. Contour gently
convex, with a very slight and narrow posterior slope. Surface with about thirty
distant, regular, elevated concentric lines.
Size.—Height 12 mm., length 19 mm.
Localities.—Six specimens from Marwood are in the Barnstaple Athenzum ;
one from Marwood is in the Museum of Practical Geology; and Sowerby’s type
from Marwood is in the Woodwardian Museum.
Remarks.—This species seems to characterise the Sloly Beds, and to be variable
in shape, its transverseness decreasing with age.
Its name was changed by M‘Coy on placing it in the genus Nucula, but as it
belongs to Ctenodonta or Palexoneilo, it may resume its original name. The pos-
terior depression is very narrow and indistinct, perhaps even more so than

appears from our figure, which was carefully drawn from the very indistinct type-
Specimen and its cast.
Affinities—From Ct. lirata it differs in its flatness and even contour, its smaller
and plainer posterior slope, and its finer striz.
Ct. elliptica is much less transverse, but the larger specimens of the present
shell seem gradually to approach it, though still differing in having a narrow posterior
margin, and in not having the striz so broadly parallel to that margin.
The North Devon shell, referred to Nuculites latissimus, Phillips, sp., is more
transverse, less ovate, less truncated behind, and more finely striated.
Palzoneilo filosa, Conrad,' is a narrower shell with a much wider posterior
slope and finer strize.
Sanguinolaria gibbosa, Goldfuss,’ not Sowerby, which Beushausen® refers to
this genus, is rather similar in shape and markings, except that, according to the
latter author, the ridges are numerous and crowded near the margins, and the shell
shorter and the umbo higher.
The Carboniferous Ct. Hallii, Barrois,* agrees in shape, but differs in its less
defined and regular ornament.
Cucullea antiqua, Sowerby,’ the type of which igs in the Museum of the
Geological Society, is almost exactly the same in shape, but it has a long stout
clavicular ridge, is more convex, and is described as smooth. Sowerby does not
appear to unite the two shells, which he places in different genera, though giving
them the same specific name.

margins, especially the inferior margin. Surface covered by about forty very
distant, fine, sharp, elevated, erect, concentric threads, which occasionally become
slightly irregular, are closer and smaller on the supero-lateral parts, and are
crossed in the marginal regions by numerous microscopic radiating lineations,
which, however, may possibly have been induced by other causes instead of being
a true testaceous ornament.
Size.—About 24 mm. long, 22 mm. high, and 3 mm. deep.
Locality.—In the Barnstaple Athenzeum is a fine but not very perfect example
from Bradiford. Phillips describes his shell from South Petherwyn.
Remarks.—Our figured specimen exactly agrees with Phillips’s figure, so that
there can be no doubt of its identity. As its umbo and hinge are hidden, there is
little direct evidence as to its genus. In general shape it closely mimics shells
hike Astarte, but its resemblance to adjacent species leaves little doubt that it
belongs to the present genus.
Its transverse ornament is precisely similar to that of Ct. antiqua, Sowerby, sp.,
and it is quite within the range of possibility that further specimens might
afford ground for regarding it as the aged form of a variety of that variable shell.
The present form has, however, such a distinctive, obliquely subquadrate
shape, that, judging from what we know of it at present, there appears to be just
grounds for believing Phillips to be right in regarding it as a distinct species.
Affinities —Paracyclas lirata, Conrad, as given by Hall,’ is identically orna-
mented, and approaches it in shape, but is more convex, and has much fewer ribs,
and could claim kinship only on the assumption that the present species did not
belong to the Nuculide.

arched, bearing, at least on the posterior side, very numerous, small, short,
parallel, oblique teeth. Posterior hinge-margin long, nearly straight, slightly
oblique. Posterior margin narrow, and so deeply convex as to be nearly
subangular. Inferior margin very long and gently convex. Contour of back
moderately and evenly convex. Surface covered by numerous minute, irregular,
parallel, sharpish, concentric striz, one or two of which are definitely larger than
the rest.
Size-—Height 10 mm., length 27 mm., depth of one valve about 3°5 mm.
Locality.—A fine specimen and its mould from Sloly are in the Barnstaple
Atheneum. A cast from Barnstaple in the Museum of Practical Geology may
belong to the same species.
Remarks.—As its interior is not certainly known its genus cannot be
decided. The cast from Baggy differs so much that it is very doubtful if it is
identical. The species appears to be well characterised, although there may be
a little uncertainty about its exact shape, owing to the great amount of squeezing
which the beds have evidently undergone. It occurs in the Lingula squamiformis
beds.
Affinities.—Leda perdentata, Barrande, which belongs to the genus Nuculites,
may possibly prove to be the same species.
The vaguely figured and described Nucula latissima of Phillips, seems broader
behind, and is more likely to represent the shell described below than the
present species.
From Ctenodonta livata and Ct. antiqua it differs by its much greater length,
and by its much finer and more irregular ornament, as it shows little or no signs
of the lofty regular concentric bars which cover the surface of those shells.
Cucullella tumida, Sandb.,’ which has somewhat the same dimensions, differs
in being still longer and more trigonal.
Nucula solenoides, Goldfuss,? has a concave hinge-line, and N. prisca, Goldfuss,’
appears to be more trigonal.
Palxoneilo attenuata, Hall,* has a median constriction on the back; and
P. sulcatina, Hall, though closely resembling it, seems to have a loftier umbo and
more lamellar ornament.

its surface is undescribed. It may be distinguished by having a loftier umbo and
blunter anterior side, and perhaps by its hinge-line.
Ct. hercynica, Beus., is a similarly doubtful analogue.
Sub-genus—KorneEnia, Beushausen, 1884.
Beushausen separated this as a genus on account of its bent hinge-line and the
absence of a marginal area to it, giving Nucula Jasii, Romer, as the type species’;
but in his later work (1895) he sinks it as a group of Ctenodonta.
6. Crenoponta (Kornenta) cf. opsotnta, Goldfuss, sp. Plate XII, fig. 10.
Description.—Shell of moderate size, very transverse, very convex. Umbo
large, flattened, incurved, and probably proximate, situated at or about the anterior
third, and tending forward. Inferior margin long, nearly straight. Lateral
margins apparently narrow and very deeply convex. Hinge-line gently arched,
nearly as long as the shell, and very wide, imperfectly seen but bearing four or
five very large, massive, vertical teeth at its extremities, and probably many
others between them, which appear to become very minute near the umbo.
Contour deeply and regularly convex, being steepest on the anterior side. Shell-
Structure very massive. Surface unknown. No clavicular process.
Size.—A. defective valve measures about 17 mm. high, 30 mm. wide, and
7 mm. deep.
Localities. —Two casts from Braunton and one from Baggy Point are in the
Museum of Practical Geology, and another from Frankmarsh is in my Collection.
Remarks.—These fragmentary casts show no signs of any clavicular process.
They seem remarkable for the great size of the hinge and of the teeth; the latter
having an appearance of being joined by slight transverse bars, which may,
however, be due to accident. They certainly seem distinct from any accom-
panying species; but unfortunately the most characteristic specimens are too
imperfect for figuring.
They bear resemblance to Nucula obsoleta, Goldfuss,”’ and to Cucullexa Jasit,
F, A. Romer,’ but in neither case is it easy to form an accurate idea of the exact
shape of these German shells. Beushausen,* indeed, describes a shell more fully

NUCULITES. 107
which he refers to Goldfuss’s species, with some, as ib seems to me, very
reasonable doubt.’
3. Genus—Nvcutites, Conrad, 1841.
“ Hquivalve ; hinge with cardinal teeth as in Nucula, but apparently uninter-
rupted beneath the apex; an interior rib, like that of Solecurtws, but narrower,
extends from the apex either direct or slightly oblique towards the base, never
passing much beyond the middle of the valve.”
Conrad thus defines his genus, remarking that it has ‘“* much the exterior aspect
of Nucula,” but that the deep sinus in the cast gives the same distinction as
between Solen and Solecurtus, and that it has no fossettein the hinge. N. lamellosa,
Conrad, is the first of the nine species which he places under it. According to
Fischer some of these species belong to Nucula, and some, with a clavicular ridge,
to Oleidophorus, Hall, 1847. But Hall in 1883-5 appears to have sunk the
latter genus, referring such ridged shells to Nuculites, and (inter alia) Cleido-
phorus ovatus, Sowerby, sp.
Conrad’s generic definition seems perfectly clear and valid, whether or not he
has been consistent in the species he has referred to it.
Cucullella, M‘Coy, 1851, Adranaria, Munier-Chalmas, 1876, and Cadomia,
de Tromelin, 1876, appear to be synonyms.

Description.—Shell rather small, oval, very convex and transverse. Umbo
small, low, rounded, turning rather forward, situated at or about the anterior fifth
of the length, and apparently bearing internally a median clavicular process
which extends halfway down the back. Hinge-line very long, rather curved, with
about four very minute, thin, radiating, central teeth under the umbo, nine large,
oblique, strong anterior lateral teeth and about forty short, rather stout, perpen-
dicular, parallel posterior lateral teeth. Anterior margin broad, and deeply and
evenly convex. Inferior margin long and very slightly convex. Posterior margin
much produced, and so deeply convex as to be almost bluntly angular. Contour
of back very convex, sinking steeply in front. Surface ornamented by about thirty-

five very regular, minute, parallel, very distant, erect threads. Shell-structure
apparently thick.
Size.—Height 12 mm., length 24 mm., depth of one valve 4 mm.
Localities.—T wo specimens from Fremington are in the Barnstaple Athenzum ;
one defective specimen from Frankmarsh in my Collection; and one very
obscure specimen from Barnstaple in the Woodwardian Museum.
Remarks.—Phillips’s description of his Nucula latissima is only—*‘ its great
width is its chief characteristic.” His figure is only the outline and hinge;
his locality Pilton. All that can be said is that the present shell seems to agree
exactly in shape, though Phillips’s drawing perhaps implies rather fewer teeth.
I have been unable to find his type specimen, and can therefore only refer our
shell to his species doubtfully.
Again, Phillips identifies a shell from Meadfoot Sands with Sowerby’s Cucullxa
ovata, and at the same time refers to a small doubtful specimen from Pilton.
To whatever species the Meadfoot fossil may belong, the specimens before us
appear distinctly to differ from Sowerby’s shell by their much greater transverse-
ness and less ovoid shape, though, as he has only figured a cast, the ornament
cannot be compared. The doubtful specimen which he quotes from Pilton
may possibly belong to the present species.
The existence of a clavicular process is not very certain, as the surface of the
figured specimen is decayed about that part. Hence the genus must remain doubtful.
Affinities.—Nucula Krotonis, F. A. Romer,’ which is the same as Cucullella
tenwiarata, Sandberger,® is similar and possibly may prove identical. It seems,
however, to differ in its more ovate shape. It appears, according to Beushausen,
not to have a true clavicular ridge.
Ct. lirata, Phillips, sp., has a slighter hinge-line, fewer and stronger threads,
no clavicular ridge, and a posterior constriction and emargination.
Nucula tumida, F. A. Romer,* and N. polydonta, F. A. Romer,’ seem shorter
and more oval, and the former at least has no clavicular ridge.
Nuculites oblongatus, Conrad,® sp., which Hall’ compares with Nucula (Nucu-
lites) ovata, Phillips, appears to differ in having longer, closer teeth, forming an
unbroken sweep and not extending so far in front.

The arrangements of the teeth show that the first and therefore probably both
of the following species do not belong to Dolabra, M‘Coy. There seems no reason

Description.—Shell large, convex, very variable in shape. Umbo large, more
or less anteriorly situated, elevated above the hinge-margin, incurved, tending
obliquely forward, and more or less truncated behind. Hinge-area large, flat,
triangular, transversely striated. Hinge-line straight, large, shorter than the
length of the shell, bearing a few subparallel, long, transverse teeth both before
and behind. Anterior margin roundly convex, narrower than the posterior
margin. Inferior margin slightly convex, usually oblique. Postero-inferior
corner produced, rounded. Posterior margin oblique, straight or rather convex.
Contour of back very convex, greatest depth on line from umbo to postero-

inferior corner. Surface covered with numerous sharpish, rather irregular
transverse lines and undulations of growth.
Size.—Specimens measure 55 mm. long by 55 mm. high by 35 mm. deep; or
40 mm. long by 35 high by 20 deep.
Localities —Numerous specimens are in the Woodwardian (including Sowerby’s
types) and the British Museums, the Barnstaple Atheneum, the Museum of
Practical Geology (including the seven specimens figured by Phillips'), and Mr.
Hamling’s and my own collections from Sloly, Marwood, Shirwell, Baggy Point
and Knowle Quarry near Braunton, North Moulton (one), and Tiverton (four).
Remarks.—Sowerby and Phillips have divided the Cucullex, which are so
common in, and so characteristic of, a zone in the Marwood beds, into five or six
species ; but it may be observed that at least Professor Phillips had great doubts
as to the correctness of so doing.
Of C. angusta, C. unilateralis, and C. trapezium he writes, “The three last
species are so very closely allied, that on looking over many specimens we find it
doubtful whether the differences observed are other than those of degree. The
same thing is observable at Marwood in regard to Avicula damnoniensis, which
varies so much in its proportions as to require the pointing out of three distinct
forms.”
M‘Coy, uniting OC. amygdalina to C. unilateralis, and C. trapezium to OC. Hardingit,
reduced Phillips’s five species to three. But OC. amygdalina is intermediate
between C. angusta and C. unilateralis, and C. Hardingit bears much the same
relation to C. angusta which C. amygdalina bears to C. trapezium. It may be said
indeed, on the other hand, that these five forms, though bearing evident relation-
ship, are easily distinguishable, and can be definitely defined, and that it is possible to
class specimens under them. But, even so, it soon appears, when any large number »
of specimens are under examination, (1) that hardly any two that may be placed
uuder any of these forms are exactly alike, showing that each group is merely a
collection of very variable shapes bearing some resemblance in general features ;
and (2) that many specimens may with equal justice be classed under more than
one of the five forms: that is to say, that they not only vary within themselves,
but run in all directions into each other. It seems, therefore, necessary to believe
_ that we have really only a single very variable species, and that the five forms are
not even local varieties, but simply accidental variations of shape. It must further
be remembered that these fossils have been subjected to a good deal of squeezing and
pressure, and that consequently some amount of the variability of the specimens
may be due to that, and therefore have no real zoological existence at all. Lastly
it may be remarked that the five forms described by no means exhaust the shapes
which the species assumes; and that the only consistent course is either to
1 1841, Phillips, ‘ Pal. Foss.,’ pp. 40, 41, pls. xviii and xix, figs. 66—70.
CUCULLAA. lll
describe a number of new forms in addition to those already described, or to
unite all in one single species.
I should perhaps hardly have ventured upon the latter course had not my
own view been confirmed by the remarks of Mr. Townshend Hall, who has
collected at different times vast numbers of these fossils, and who remarked to
me, when first I saw his collection, that he thought they ought all to be united,
and that he had arranged several hundred specimens in one continuous chain.
He has since favoured me with the following note, which he made in 1877.
* Between CO. amygdalina on the one hand, and C. angusta on the other, there are
various intermediate forms, to which the names C. Hardingi, unilateralis, and
depressa have been given. Is C. Hardingii a good species? C. unilateralis is the
mean between C. amygdalina and C. trapezium.”
On examining the specimens at Barnstaple with me, Dr. Hicks expressed
himself as inclined to the same view.
For the sake of definition it may perhaps be convenient to retain the five
names, amygdalina, Hardingii, wnilateralis, trapezium, and angusta for the classi-
fication of shapes, provided it be understood that no zoological import be attached
to them.
In figuring the species I have attempted chiefly to show forms intermediate
between these named varieties.
It may be observed that young shells are often flatter, and have smaller and
less prominent umbones.

Description.—Shell large, convex, slightly inequivalve and inequilateral,
variable in shape, trigonal. Hinge-margin short, straight, about one-third of the
length. Umbones prominent, incurved, rather distant, inclined somewhat forward,
and situated subcentrally. Cardinal area apparently rather broad and concave.
Anterior margin broad, prominent, and roundly convex. Inferior margin oblique,
nearly straight. Postero-inferior corner steeply rounded. Posterior margin
oblique, nearly straight, meeting the hinge-margin at a low obtuse angle. Contour
deeply convex on the line of greatest depth from umbo to the postero-inferior
corner; before which it slopes flatly out to the margins, becoming slightly concave
near the anterior end of hinge-line; and behind which it is almost perpendicular,
becoming concave to form a small angular posterior wing. Surface smooth?
112 DEVONIAN FAUNA.
Anterior muscle-scar small, circular, situated marginally immediately under the
anterior end of hinge-margin.
Size.—Height 58 mm., length 78 mm., depth 40 mm.
Localities—There are three specimens from Marwood in the Museum of
Practical Geology, two of which were figured by Phillips; and several from
Marwood in the Woodwardian Museum.
Remarks.—This species is remarkable for its short hinge, and its peculiar
trigonal, wedge-like form. The few specimens known are very various in shape,
but appear to be probably different from the common and equally variable
Cucullea by which they are accompanied. Phillips observes, “The extreme
depression of this shell (compared with the former) is remarkable, and does not
depend on distortion or pressure, but it is very uncertain how much must be
allowed to accidental or local variations of form.”

Description Cast minute, convex, semi-oval, transverse, and very oblique.
Umbo small, acute, oblique, tending forward, distant, elevated a little above the
hinge, and situated between the anterior one-third and one-fourth of the length.
Hinge apparently broad and massive, equal (or very nearly so) to the greatest
length, bearing two very long and strong obliquely transverse teeth. Anterior
margin very narrow, obliquely convex. Inferior margin very long, obliquely
straight in front, roundly convex behind. Posterior margin almost vertical,
broadly convex. Contour of cast concave on hind wing, roundly convex on the
line of greatest depth from umbo to postero-inferior corner, depressed behind the
line from umbo to antero-inferior corner, and very deep in front. Shell-
structure very massive.
Size-—A specimen measures 2°5 mm. high by 3°5 mm. long.
Localities—In the Barnstaple Atheneum is a specimen on the same slab as
Crenipecten awritus from Bradiford, and in the Porter Collection are two specimens
on a Slab from Poleshill.
Remarks.—Only the cast of this minute shell is known. It appears evidently
to belong to the genus Parallelodon.
