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-

A

few somewhat similar specimens have been obtained

from mndcly dredgings by the Goldseeker in the

Jlorrty

in the Norwegian fiords.

were to be found possessing some Nubecnlariiie characteristics, but

that the Jlilioline affinities uf such specimens could always

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.
