Mr. H. I). Stewart (lit) in "The Cheiiiistry nf the Oil-Shales." part III of the inenioir ol
the Ciciilocical Survey (Scot hind), enters fully into the proliiilile oriKiii of kerotieli. the term that
has iK'eii applied to the earlmnaceims matter in shale that (sives rise to I'luih' oil in distillation

He |M)iiits out that the carlMinaceous matter, with clay, was prolialily dclKisited at the iKittoni
of lattoons: ami that vetjetalile niatter, such as. for instance, pine-pollen, or lyi'o|«id-spores, oi
animal niatter such as minht lie derived from eiitomostiaca (of which .some shales are larjtcl)
iiiadi! up), or, in fact, any kind of orpinic matter, may, throunh the action of iniciolM's, liav(
been converted into kero({en.

His conclusion is that "oil-.shide may 1m' comiMiscd of (1) vegetable matter which has lii'ei
made into a pulp liy inaceration in water and preserved liy combiniii); with the salts in solution
(:>) richer materials of many kinds. .•>uch as spores, which nature has provided with means foi
some protection againsl decay; and Ci) a proiMirtion of animal niatter. '

It is probable that the waters in which lived the fishes alniut to be desi'ribed, were cut of
t<i a Kicat extent from the sea. and formed the lagoons in which the material that produced tin
shales wa.s deposited.

The nunilH'rh'ss remains of fishes in some of the Iwds can lie attributed only to the occasiona
whoh'sah' destruction of the fishes.

.Vny sudih'ii or in;iterial change in the comlition umhT which the fishes existed would resuli
in lo-i- of life. Such unfavourable conditions might Ix' caused by the resumption of free com
nmnicatioii In'tween the lagoons and the open sea. or the lagoons may have felt the iiiHuenci
of drought, and have, at times, almost disappeared.

The apiM'arance oi the fishes in their fossilized stale suggests differences in the comlition
affecting thorn fter (h'ath and piior to entombment in the vegetable mud forming the iHittoni

The apix-arance of some seems to indicate that decoinposition. to a greater or le.ss extent
took lilaee in the water, while others .seem to have been desii'catcd prior to their (iitombmeiit
Decoinposition w.nild result in an increa.se in the ih'pth of the body, and, according to the laps:
of time, a later partial or eomph'te disintegration with a more or h'ss scattered disposition o

I'liKViors W'dHK.

In the Report <if Progress for lS7ti 77, (Jeological .><urvey of Canada, 1S7S, the (hstriliution
and geological age of the AllM'rt shales are discussed at h'n^'th liy I'rofe.s.sor I.. W. Bailey, and
Dr. H. \V. Klls, in their joint "Heport on the lower CarlMinn'erous belt of Albert and Westmor-
land counties, N.B., including the .MImtI Shales." The general conclu.sion reached at that
time, as to the geological age of the shales, was that they occupied an almost basal [losition in
the lower Carboniferous formatimi, the lowest memlxT iM'ing a conglo'Mcrate, of, at that time,
unknown thickness. The presence of fo.ssil ti.shes behuiging to the I'aheoniscidu' was relied on,
in great measun , as an index to the age of these Ixds. Comment is made on the alunidance
of fishes, in marked contrast to the paucity of the plant remains, which were, however, con-
.sidered to Ix" referable to typical lower Carboniferous species (p. 3,")").

In 1S,S0, an opinion was expressed by Profcs.sor Baih'y and Drs. (1. F. Matthew and R. \V.
Klls, in their "Report on the Geology of Southern Xew Brunswick, etc." (deological Survey of
Canada, Report of I'rogres 'or 1.S7S 70) p. Hi 1). that ''Stratigraphically. the beds of Alliert
shales, as develoiM-d in Albert and Westmorland counties, may belong to a lower horizon than
the Carboniferous, and iriay constitute an upper |Hirti(in of the Devonian, but the prevailing
fos.sils, both fishes and plants, seem to indicate a lower Carboniferous age."

.\t a later date in his "Report on the (ieological Formations of Kasterii Albert and West-
morland counties in Xew Brunswick, etc.," (Vol. I, New .Series, 1S.S.')), Dr. Klls retained the .\lbert
shah's in his divisions of the lower CarlMiniferous, recognized in Xew Brunswick next above a
iMisal conglomerate, presuni.ibly alHint 2(M) feet in thickness (p. Xi K.) A general section of the
lower Carlxmiferous rocks in this area is given, in ascending order, in this report as follows: —

genera as, although dilTering specitically from those of the Carls mi ferous Sandstone series of
Mid anil West bithian, and other liwalities in Scotland.

This series of rocks is consiiiereil, liy the geologists of the Hrilish Survey, an<l others who have
niiwle a special .study of the oil-shale fields in Scotland, to form the l>.H.se of the CarlKiniferous
system in that country. According to them the Carlxiniferous sandstones are the downward
continuation of their CarlKJniferous Limestone series, and rest conformably on the upper Old
Re<l Sandstone. The Calcifi-rous Sandstone series includes tish-lH'aring shales, which are almost
identical in com|Hi8ition and physical characters with the AUhtI shales.

The great similarity of the fish fauna of the shales in the two countries can lead to no other
conclusion than that they are synchronous deixisits.

It is believ(Kl, therefore, that the age ascrilHKl to these (ish-lx-aring shales in Scotland should
also Ik- ascrilxHl, on the evidence of their fossils, to the Albert shales of New Brunswick, and
that the strata in the two countries are g(K)logical e<|uivalents.

With the foregoing intHxluctory remarks relative to the AlU-rt shales of .\lbert and West-
morland counties of New Brunswick, the mode of their occurrence and their probable age, ««•
may [lass on to a short reference to Dr. Charles T. Jackson's work on this particular fauna, and
of that of a munlx-r of distinguished palii'ontologists in later years. Vreceding the descriptions
of the s|X!cies of Palieoniscid fishes so well and abundantly preserved in these rocks is a state-
ment of the material on which the descriptive [sirtion of this re|)ort is based.

Cambridge, the oriKinal of .lackson's li^inre 1. plate I. is imperfect in many respects. The dorsal,
anal, and caudal fins are but partially preserveil, while the other fins, as well as the head, are
missiuf;. In most of the scales the liner details of ornaincntalion are obscure, and the posterior
marnius are broken. .Mthounh the scales are not. as a whole, well preserved, yet, some of Ihein,
well forward on the flank, on clo.sc examination, show that the same .style of striatiou exists
in them as in the type of li. (■(lirn.-i. The principal c-haractcr apparently relied on, as a dis-
lin^uishiiiK one iM'twi'cn this spc^cies and H. niini-^i, was the implied difTerencc in the scale

I'ahninisciche as a whole, may be expected to be most aceciiluated ill the Hank siales for some
little distance back from the head. The scales of /i". nlhirli were evidently regarded by Dr.
.lacksoii as beiiif; smooth, as in the original description they are referred to as licinn '■brilliant,"

to be "distinctly striated parallel to anterior and lower inarciiis." a description that. t<i be
complete, needs sonic reference to the coarse, obli.iiie stria' which are present in the upper back
portion of the scale surface. To the writer the striatiou of the scales appears to l«' the same in

reliance being placed on the characters displayed. The original of figure K includes .seal
some distanc(^ in advance of the dorsal and anal fiiis, in which the characteristic striation of i

OviT B (Idzcii <^xttin|)lrs of a liirni" fish from tlif shales of thi' All«'rt iiiiiics arc now in the
possession of this Survey, and are in the writer's ojunion referable to this species. In fact, of
the spei'irneiis of fossil fishes from this locality, nil the lar^e ones appear to Iw'lonj; to this species.
They raiiKe in length from about IS.j em. (approximately of the size of the type specimen) to
nearly U."! .'i em. or about U inches. The specimens depicted by Jack.son in plate I, figure Ti,
anil plate II, figure 1, arc also U'lievcd to belont; to this species. The orijrinal of Jackson's figure
4, plate I, the ty|H' of /'(i/ir«« i vrii-v jiicl,siini. Dawson, is not available for study, but, judgiii);
from the figure, it is presumably not ilistinct from /■,'. hriiwni. lis h'Ugth, as stated by Dr.
.Jackson, was originally 1"> inches.

Jackson's original dcscripiion appeared as follows, (m page 22 of his reiKirt: "PI. I. Fig. 2.
This Ix'autiful fish was found by Mr. Brown, the captain of the mine, subse(|ucnt to my first
visit to Hillsboro". It is one of the largest, or full grown species. It was unfortunately broken
ill the operation of extracting, but it still is a very valuable specimen. This being the first fossil
fi.sh found by the chief miner, I have named it I'nhummint hrrwnii.

missing, it having Ikm'II broken in getting out the specimen. I)or.sal fin, a little iH'hind middh^
of ixxly, (ip|M).site, or rather a little in front of anal."

The original descriptions of the specimens shown in plate I, figure 4, and plate ll, figure 1,
arc as uiidi^r: —

"PI. I., Fig. 4. This large and elegant fish was most unfortunately broken in splitting it
out fnrni the rock, only the posterior part of it having l)een saved in a fit condition for delinea-
tion. The whole length of the fish wa> originally fiftei'ii inches. That portion which remains
entire is '> 1-2 inches long; it was broken otT through the ixisterior edge of the dorsal fin. It
was an old fish, as is evident from the appearance of the scales which are thick, heavy, and have
their striations in part obliteratetl, whih' the .serrations are extremely sharp and deep. The
seah's are i-loiigated rhomboids, and hav(^ many stria' upon their surface which run parallel
with their upper and lower margins. Caudal scales, acute lozenges. They tin. down on u|)per
division which is long and covered with scales. Hays of tail come olT very n.- nictly, exclusively
fr.)m under side of upper divi.sion, and the tail is unei|ual or heterocercal. I'ntil we obtain
an entire spijcimt-n, |K"rhaps it will Ix? prudent to abstain from giving a specific name. It is a
spcM'ies of the genus /'n/ironisrM.v.

" PI. II., Fig. 1. This species s;) nearly resembles the I'alitDiiixcux deairii.'! of Sir Phii.,i M.
d(^ Kgerton, as on first view to |)ass for it: but on examining the lines of strite, we are forced to
regard it as another species. The four great dorsal scales, anterior to the dorsal fin, exactly
resemble in form tho.se represented in Sir Philip .\I. de Hgerton's plate. (See Quarterly Journal
(ie;ilogical Society of London, for IS19.) The .scales of one specimen* are striated, parallel with
the su|X'rior an<l inferior margins, and are deeply and acutely scrrattxj on their ptwterior edges.

smooth, are soinetinies s<'ulptured to a slight ixtent. This sculpture has liecn best observed
in the dorsal and anal tins of the type specimen. In the more anterior part of the tins, it consists
of a feeble ol)li(|iie striatioii of the front margin of the joints, while more posteriorly ilu'ir hind
mar)!ins develop minute serrations.

occupies alwiut one-tifth. The caudal pedicle is slender, its depth beiii); alxiut twci-fifths of the
greatest depth of the trunk. In siihr view, the dorsal outline, moderately Hat in advance of
till' dorsal fin, descends rapidly near thi' head, which is rather short and obtusely |Kiinted. The
depth of the trunk is much diminished b'^twecn the dor.sal and anal fins, the line of the base of
these hiis beiiij; oblique to the longitudinal axis of the hsh. The tail is deeply forked and the
upper lobe considerably i xcced.-! the lower one in leiijjth.

The luandibular suspcnsorium is apparently obliiiue. The teeth, as seen imi>erfectly in
one specimen only, seem to l)e arranged in two rows, after the manner of the (teiius, viz., with
.small teeth in an outer row, and large,- ones, at intervals, fonning an inner row. In all
the specimi^ns the head is unsatisfactorily preserve<l, and no definite statement can be made
regarding the sliapu and disi«isition of the buiies.

In the fins, the ray.s are articulated throughout except the most proximal part of the first
two or three rays of the pectoral. The dorsal fin, plate IV, fig. 1.', is triangular, with a ba.se
nearly eiiual to the length of the anterior Ixmh'r. The po.sterior margin is straight or slightly

concave and ei|uals the base in length. .\s exhibited in the type spcciin plate I. fig. 2, and

tudinal striation or groove, which begins nc^ar tli(' base and is ;il first superficial. This groove
deepens and become,* more dc led near the mid-length of the tin, and culminates in a subdivi-
sion of the ray not far from the iM)sterior margin of the fin. Di.stally a second, and apparently
also a third sulnUvision, may take place. The joints retain very much the same length ilistallv,
as proximally. with the result that their length relative to their thickness is greatly increased

The iH'etoral tins are not well k'-owu in st of the siieeiineiis seen. In one specimen,

however. r..Mreseiited in figure 1, plaie VIII, the left one of the pair is fairly wvll preserved,
and from it we can ju.lge of its pro|K.rtions and relative size. In this spi'dmei. ihe tin is spread,

Its length, measured in a straight liiu^ from the l.a.-e to the anterior distal end. is h^ss than that

The Hank .scales near the head are sculptured liy slriations, haviiiK a (jeiieral lonniludlnal
direction, and nuinlM'rinn from aJHml sixteen to i ighteet or twenty. I'nder a lens they have
a decidedly ruKose appearance. These strialions cover the whole of the exposed part of the
srale, and extend forward in the over-lapped part to near thi' front inar);in, alon^ uhich there
is a narrow smooth iMirder. Most of the .striations are continuous Ihrounh the lentilh of the
scale to its |M)sterior margin. Imt a few ar<' shorter anil either merce into adjacent slriie or are
interfered with by stria' obliiiue to their course. In the lower part of the scale the strialions
are generally parallel to the lower margin and curve vip with it anteriorly. Thii-<' aliovc assume
a more or less oblicpie direction backward and downward. This ditTerence in the direction of
the slrialion in the upper and lower parts of the scale is accentuated in some of the scales, where,
in the upixsr anterior half, the stri:e are parallel to the diagonal conneclin); the upper back with
Iho lower fn)nt angle of the scale, while those Ih'Iow the iliagonal arc parallel to the lower margin.
The stria" arc often more or less curved, resulting in slight variations in the general longitudinal
direction. Th(^ iHisterior margin is inilcnted by the striie, the result being a conspicuous
.serration of that part, the numlM'r of serrations depending on the numlior of stria' at the back
margin. In the type specimen, and in some others in the collcctirm of the (ieological Survey,
the flank .scales, as we pass backward toward the tail, gradually become smoother, the place of
the striations, as they di.'^appear, iH'ing taken by a dimini.shing number of |)unctations, plate V,
fig. 3, but it is observed that the .striali<«is persist most near the anterior and po.sterior margins
of the scales. As the height of the scale is reduce<l there is a corres|K)nding rciluction in the
nunilM'r of the [Kisterior dent iculat ions. When the tail is reached the scales have iK'conie almost
smi/oth and there are fewdenticulalions. In the Ixxly prolongation of the tail the scales arc(|uile
smooth, with entire margins. In .some .specimens in the collection, notably in the largest one
obtained in the summer of 1!K)S, there is a very general iM'rsistence of the strialions through-
out the length of the flank, even well <m to the upper lobe of the tail. In difi'erent .specimens
there are observed various dcgrc>es of development of the longitudinal stri:e of the scales in
the more i)ost.rior |M)rtions of the flank, and although at first it was suspecte<l that more than
one s|M'cics of Kloiiiclilhjix was represented by the larger specimens fri'm the AllM'rt .shales .s,i

From alxnit twelve to fifteen enlarged. imbri<'ating. dorsal ridge scales extend from a short
distance back of the head to the dorsal fin. They are largest midway between the head and the
Hn, at the highest [x).... of 1\k l)ack As, in most of the specimens, these scales are badly
crushe<l, and broken at the edges, it is dithcull to obtain a clear outline of them, but the larger
anterior ones appear to be ovate, slightly longer than broad, and to attain a breadth, in some of
the specimens, of between IS and 10 mm., not taking into account the transverse curve of the
scah'. (}\\ approaching the dorsal fin they are not so broad, and arc more pointed behind. They
are ornamented by wavy, fre:|ucntly inosculating, longitudinal striic somewhat coarser than

connected tnlH'reules. In the anterior half of the scale they are represented only by ."> or ti ill-
defined ridges, having the same obliiiue ilirection. A few fine .striic occur near and parallel to
the lower margin. The conspicuous serration of the |Kisteriiir margin is due to the projecting
ends of the enamel ridges. In the posterior flank scales, plate X, fig. '.i. there are only three or
four serriitions in the back margin: the finer striations parallel to the lower margin persist, but

the .same piece of shale, aim a third specimen, plate XI, liK. :!. from llorton. from which the tinurc
aceompanyiiiK Dawson's (h«cri|>tioii was evidently principally preparinl.

This fish is short ami robust, the mamlilmlar .su.siK-nsorium is apparently nearly vertical,
the head is blunt in front, and a row of eiilartjed ridnc .scah's passis backward from the occiput
to the dorsal tin, and occurs ajiain in advance of the caudal tin. Similarly enlartjcd scales arc
present in a single row alons the iM'ily. These characters su^Kcst its beinu referable to Tra-
• luair's neuu« Cam^'ms rather than to KhmUnicMhys, to which genus it was a-ssigned when first
described.
