THEseries of papers, of which this forms, for the present, the con-
clusion, has now been in process of publication for three years.
During the whole of this time the work of making gatherings, and
the examination
of
the material collected, has been in progress, and
this has naturally resulted in the discovery of a great number of
additional species, of which aome are new. Such additional species
are described in the pages which follow, and after allowing for
corrections and the withdrawal of one or two species from the list,
bring the total of forms described up to
390,
or, including varietal
forms,
399.
We have been obliged, by engagements entered into by us with
regard to other material, to relegate to Some future occasion the
publication of the results of examination and study of the living
Foraminifera which have occupied us concurrently with the ex-
amination
of
the shore-gatherings, and also the geological
study of
the forms found in the material derived from the artesian borings
at Large Acres.
We take this opportunity of recording
our
sense of obligation
to the Council of the Society for the liberal manner in which they
have afforded us scope 'for the publication of our report. We also

For
a year now past we have been keeping under observation
in the tanks which we have described at some length in
'
Know-
ledge '
*
and in this Journal,? a large number of living specimens
of these two species of Gromia, both
of
which occnr in abundance
in washings of algz from the Mixon Reef. We do not propose t o
enter into any description of the observations which we have made,
reserving these for a future paper
Among the Mixon Reef gatherings we have met with m,iny
specimens of the organism figured 011 Plate IS. figs. 1, 3. Of its
rhizopodal nature there can be no doubt, as sarcode is often found
adherent round its orifice. Beyond this we do not a t present feel
disposed to form any conjecture. It s external form and size agree
very well with
G. Dujavdini ,
and that species in the living state
frequently covers it s natural chitinous envelope with a loose crust
of
sandy mud, but the sandy envelope of
Gromia
is not apparently
cemented together with any durable medium ; it can be removed
with a camel-hair brush without injuring the living animal, which
will proceed at once t o form a second covering, which appears to us
to consist of mud separated by the pseudopodia from the surrounding
water during the assimilation of nutriment. Moreover, such in-
crusted
Gronzim,
when dried in the same manner as the shore-
gatherings are dried, shrivel up into amorphous crinkled sacs, the
nature of which could nut be ascertained from a mere casual inspec-
tion of the dried
specimens.
The specimens wliich we figure, however, are firm though some-
what flexihle. They consist of a spherical chitinous envelope
covered with a uniform layer of very tine sand-grains, which are
so closely adherent to the envelope tliat they resist any attempt :it

of
the 5ac n large roughly circular
aperture is situated
;
in the irninecliate neiglihourliood uf the aper-

visible.
A
few somewhat similar specimens have been obtained
from mndcly dredgings by the Goldseeker in the
Jlorrty

in the Norwegian fiords.

also
reports its
occurrence at Balfonr Bay, Kerguelen Island (which is far frmi
the tropics) in
20
to 50 fattionis. Brady also refers to the fact that
on the Ihitjsli coasts wild growing specimens
of Miliolina
szibrotuiidu
were to be found possessing some Nubecnlariiie characteristics, but
that the Jlilioline affinities uf such specimens could always
be
identified
by
the nature of the aperture. The aperture
of our

There is

of
rariation in
the
specimens
of
this
simplest of the Spiroloculine types, and they serve
t o
link it
up
with other Milioline species. Many
of
the specimens are some-
what rugose, and show
a
tendency t o adopt
a
subarenacous type
of
shell. This type of shell clasely approaches

A considerable number of specimens, al l more o r less eroded

Terquem's species, which was described from specimens obtained

Fragiiients of this species are not uncommonly iitet,with anlong
the coarser siftings, and we liare one or t m almost perfect speci-

all derived from Eocene strata. According to Brady, tlie species
has been recorded

Among the washings
of
inud from the Mixon Reef we have
found many specimens, more or less fragmentary, referable to this
species. Individual fragments also occur in
some
of the shore
gatherings. This
is
one of the lowest types of the Foraminifera,
the organism consisting merely of a single chamber of irregular
shape, bounded
by
thick walls of fine mud upon a chitinous tube
o r
layer. The chitinous envelope frequently extends without an
external covering of
m u d
at the oral end
of
the shell.
It often
attains to a considerable size. In some of the Goldseeker'
dredgings from the Sorth Sea, specimens half t o
three-quarters
of
an inch in length are found.

We
have one minute specimen derived from the rarely-visible
band
of
clays, named by Mr. Clement Reid the Selsey Beds,
which appears to be referable to this species.
If
so, its presence in
our gatherings is certainly noteworthy, as
H.
latidorsatum
is
one of
the most typical
of
deepwater and cold-area forms. I n the cold
area of the Shetland-Faeroe channel and in the Norwegian Deep
to the north
of
this channel the species occurs in such enormous
numbers as to form
a
true deposit
or
ooze, in which the presence
of other organisms is completely masked by the preponderance of
this species, which also attains to a considerable size.
Apart
from
this area, the records of H. Zatidorsatum are almost confined to very
deep water, except in the Arctic and Antarctic seas. As a fossil
it has been recorded from several Eocene clays in Germany and
Hungary.

This form is also obviously near to E . elegantissirnu (d'orbigny),
but is characterized by the foramina being placed in regular
lines,
so
that there is, a superficial appearance
of
external striation. The
sutures
are
flush and the sides of the shell are almost parallel, the
aboral end being a blunt cone
and
,the aperture set on the flattened
face
of
the
terminal chamber.
Terquem's specimens were Eocene fossils from Septenil, near
Paris ; ''
very
rare.
W e have several specimens, obviously fossil, which may be
.Eeferred to this species,
as
they possess the linear pnnctation charac-
teristic of Terquem's form.

We have two specimens of the pretty l itt le form figured
and described by Terquem under the name of B.
obkipua.
As,
however, the specific name oblipwa has already been used by
d'Orbigny
for a
distinct form, we have associated -Terquem's
specimens with the name of the author. His description is as
follows: Shell irregular, more developed on one side than the
other
;
sub -rotund, enlarged anteriorly, domecl posteriorly, and
furnished with
a
small spur. Domed on one side and incurved on
the other ; ornamented with very fine and curved sulci. Formed
of three whorls
of
prominent spiral layers, oblique, elongated,
chambers indistinct, the last whorl highly developed, aperture
round, situated in a very large lateral depression of a pointed oval
shape furnished with a thickened rim. Terquem's specimens were
from the Eocene
of
Septeuil, near Paris-very rare-and ours are
doubtless -fossils derived from a similar formation.

incling in an Engli .~li hore gathering of this iuiiyne a i d
well developed specimen of a species known hitherto only from the
Malay Archipelago, represents possibly the greatest surprise of the
whole collection, and illiistmtes the glorious uncertainty of work
ainl jng
the
Foraminifera. The specimen has been subniitted to
Mr. Millett, who agrees with oiir identification. Piniilar abnormal
occurrences are well known
t o
all rhizopodists, and have sometimes
been regarded as due to the use of sieves which had not been
effectually cleaned after use with other material, but sncli an objec-
tion is discounted in this instance by the fact that the sieves used
fur the Selsey material were new when first taken into use anti
have been religiously preserved for Selsey gatherings only.
Milletts specimens were from various localities in the Malay
Ilrcliipelago, where it is one of the most typical and abundant
3yeeies. We have met with it in anchor mud from Singapore, but
the 3pecimens were much smaller than our Selsey
find.
