The following Systematie List of the Maltese l'estacea
arranged according to Lamarck's Classification, with the
degree of rarity or frequency of certain of them, the lo-
calities where some of them may be found, andthe diag-
noses of several species discovered and described by the
late Mr. Giuseppe Mamo, of the Central Hospital, has been
prepared from his four original MSS. on Maltese Mollusca
and from other loose papers consigned to me by Mrs. Mamo.

As the four MSS. exhibit many variations and correc-
lions, great care and diligence have been used in gleaning the
information contained in them, and I am much indebted
to Mr. Charles A. Wright for the kind assistance he
has lent me.

I deem it proper to make the Report on Mr. Mamo's
MSS. and general Collection of Shells, whieh I sent in to
the Society of Archzeology, History, and Natural Sciences,
precede the Local List. I have also included the native
Fossil Species, so as to form as complete & catalogue as our
present information permits of the Maltese Mollusea.

Dr. A. A. Caruana' s Report on the MSS. and Oollection of
Shells of the late Mr. Giuseppe Mamo, read on the 13th
March, 1866, to the Society of Archzeology, History,
and Natural Sciences.

Mr. President and Gentilemen,—

1. I have the honor to offer you the following information
on the MSS. and Collection of Shells belonging tothe late
Mr. Giuseppe Mamo, of the Central Hospital, for which ob-
ject à Committee was appointed in January last and formed of
Mr. Furse the Secretary, Dr. F. Spiteri Agius, Mr. C. A.
Wright, and myself.

2. Before this Society of Archwology, History, and Na-
iural Seiences was instituted, T had already entered, with the
widow and sons of my deceased friend, on the preliminaries of
sale of Mr. Mamo's copious collection of shells, that ;t
might remain in some one or other of the Publie Educational
Establishments in this Island, and his MSS. on the
Gaulo-Maltese Fauna Molluseorum had been handed over to
me that I might examine and publish them, and thus offer a
publie homage to my lamented and learned friend.

For this purpose I had prepared a careful eatalogue of
the genera and species, with the Author's name, the country,
and number of examples, and all such other particulars which
I found noted down. I have omitted the specifie name of
many examples, especially of the Acephala, because many of
them bear numbers referable to Catalogues, which neither
Mrs. Mamo nor I could find amongst the papers in my pos-
Session; and further, because others had parted with their
labels, and I did nut wish to undertake the responsibility of
naming them.

MI. n nd

3. The examples were very well chosen with reference to
variety, distinctive characters, age, and size, and have been
kept in a very good state of preservation.

Some of the genera, chiefly amongst Land Shells, con-
tain many species. The genus Helix contains about 371
named species out of 614 in Miss Catlow's Conchologist's No-
menclator; Bulimus 121 species; Clausilia 50 species; Cy-
clostoma 61 species; Pupa 36 species, etc. Of the convoluted
shells, the genus Conus contains about 73 species; Cyprca
64 species; Oliva 59 species. Of the Canaliferous, there are
98 species of Murex, and 24 species of Triton. Of the Pur-
purilerous, there are 24 species of Purpura, 17 species of
Cassis, 11 species of Dolium, and 40 species of Buecinum
and Nassa. Amongst the Nymphaeea there are about 30
species of Tellina, and 10 species of Lucina 5 of the Venuses
98 species, and Cytherea 18 species; Arca 29 species; Car-
dium 25 species; etc.

4. Mr. Mamo's Collection is not classified; but from the
Catalogue I have prepared, I have extracted this Prospectus,
(which being rather long Ishall not read without your leave),
arranged according to Woodward's natural Classification.
I have followed the highest authorities at home—such as
the late Professor Forbes' in the History of British Mol-
lusea, and Professor O wen's in the Hunterian Lectures and
Catalogue—in choosing Woodward's, in preference to other
more recent natural Classifications. Moreover, as many of
the genera have been recently separated and subdivided on
account of generie and typical differences into other genera
and subgenera, I have profited in this respect by Chenu's
Malachology in adopting those alterations, which are gene-
rally admitted, in this arrangement. For instance, I have
separated from the 'Tritons on Chenu's authority, the T. cla-
thratus, Sowb., and T. anus, Lam., which with T. ridens, form
the subgenus Persona, Montf typically different from all
other Tritons in the denticulation and distortion of the inner
lip, which give them really the appearance of a mask. "The
Dolium pomum, Lam., and D.latilabrum, Kiener, compose
at present the genus Malea, Valenciennes, widely different

ui. TEM.

from Dolium on aeeount of the columellar lip; and so forth
with Typhis, Nassa, Azeca, Zua, Aplustrum, Seaphander, etc.

Thus classified, Mr. Mamo's Collection of shells repre-
senís all the Classes, Orders, and Sections of Woodward's
Classifieation, and 66 families out. of the 81 natural families
of the same, exclusive of the Tunicata, and Cirripedia. Tt
comprises 290 genera, of which 15 are Cephalopoda, including
the Foraminifera, D' Orbieny, for which I could not find
another place in this arrangement, though Iam aware that,
after Du Jardin, it is admitted, that they form a separate
braneh of the Animal Kingdom inferior even to the Radiata;
118 Gasteropoda Prosobranchiata; 99 Gasteropoda Pulmonife-
ra; 10 Gasteropoda Opistho-branchiata; 9 Nucleo-branchiata;
9 Pteropoda; 8 Brachiopoda; and 98 Conchifera; besides 7
Cirripedia.

'These genera include about 2,451 species belonging to
special Faun:s of Land and Sea Shells of the Mediterranean,
of the Red Sea, of the Indian Ocean, ofthe Philippine Islands,
of Sumatra, and Java, of Australia, of the Antilles, of Ja-
maica, of Cuba, of the Gulfs of Mexico, Darien, and Cali-
fornia, of the Archipelago of Gallapagos, and to the Fauna of
the Nayades of the great rivers of America, besides 53 mi-
croseopie species of which some are noted as very rare,

The late Mr. Mamo succeeded in forming this copious
collection in 47 years, through the intimate relations in whieh
he stood with many eminent Conchologists and Collectors of
Shells, and his extensive correspondence testines to this.
Amongst his correspondents I may mention to you the names
of Prof. Gray, of the British Museum; Prof. Otto, of Liverpool;
Prof. Warwick, of the Zoologieal Gardens; Prof. W. V. Hen-
nack, of Plymouth; H. QOCuming, of London; Lady Selina
Henry; Prof. Liteh; Governor Sir W.Denison,of Australia; Prof.
Duffossi, of Paris; Prof. Cremiens, of Marseilles; Prof. Calioz,
of Vienna; and Prof. Maravigna, Piazza Ciantar, Aradas,
Guttadauro, and Benoit of Sicily, by whom Mr. Mamo was
held in a very high degree of reputation, for having been
the first and the only one, with accuracy and perseverance, to
form a collection, systematically arranged, of the Mollusca of

-- EE

Malta and Gozo, 18 or 14 species of which he discovered and
described, and for having supplied the Curators of the prin-
cipal collections of Europe with many hitherto unknown
species.

This is the information, I am able to give about Mr.
Mamoe's Collection of Shells. I wil now proeeed to address
you on his MSS, and other papers which I received tied up
infour bundles.

5. Most of these papers contain only lists and memoran-
da about shells received by, and sent to, several Collectors
of Shells, and Naturalists. I have put them together in one
bundle.

6. One MS., and some loose papers are of no importance
with referenceto our Fauna of Mollusea, because they eon-
tain only a short description of several known species, and
some generalities referable to Testacea, which were evidently
extracted from published works, chiefly, I believe, from
Sowerby's genera.

7. There are four more MSS, the most interesting
amongst all the papers received by me, which I have
numbered in suecession No. 1, 2,8, and 4; for they contain
à systematie enumeration of the "Maltese Molluscea according
to Lamarck, and a Memorandum No. 5 of the Maltese
Shells, which in 1854 the late Mr. Mamo placed in the
Publie Library, in complianee with Sir W. Reid's pleasure.

Although these four MSS., are in substance the same,
nevertheless they exhibit & great many variations, and in
order to extract from them a complete and accurate syste-
matie enumeration of the Gaulo-Maltese Testacea for pub-
lication, it is necessary they should be compared together
successively, with great attention and diligence, and works
which Mr. Mamo consulted should be referred to for the
purpose of clearing up differences arising from the synonyms
of words, and all those whieh imply corrections, separations
of genera, additions of new species and substitutions of
others, and for the purpose.of reducing into one MS., all
ihe observations scattered over the other four MSS.

MS. No. 1 contains a simple and very limited enu-

AUR Me is

meration of the Maltese T'estacea, disposed in families after
Lamarck, with those few modifications of Philippi in the
* Fauna Molluseorum viventium et in Tellure tertiaria fossilium
Regni utriusque Sicilie," and the degree of rarity of their oc-
currence.

MSS. No. 2 and 3 are apparently the rough copies of
Mr. Mamo, and besides many variations, and a more accu-
rate enumeration of the Maltese Mollusea, and the degree of
rarity of their oecurrence, contain, especially MS. No. 8,
many particulars about the localities where they micght be
found, and also their vernacular name:

MS. No. 4, besides a very short enumeration of Mol-
lusea as in MS. No. 1, contains the deseription of some of
ihe species discovered by the late Mr. Mamo.

8. "The following are some of the variations I have al-
luded. to :—

(4) In MS. No. 1 there is only the Clavagella mamoi,
discovered and described by Mr. Mamo, which he had sent
to England, but whieh was subsequently called C. aperta,
Sowerby, In the MSS. No. 2 and 3 there are four species,

*the C. aperta, Sowerby; C. melitensis, Calliaud; C. angula-
ia, Philippi; and C. balanorum, Seacchi, which last, being
an inhábitant of the shores of the Day of Naples, was for
the first time detected in Malta by Mr. Mamo upon a Spon-
dylus gzderopus, of which four species, the first three only
exist in the publie Colleetion of the Library. In MS. No. 4
there are four other species, the C. mamoi, O. melitensis,
and by mistake the C. aperta, which is the same as C. mamoi,
ond the C. exagzona, which is the same as angulata, Phi-
lippi.

(0) In M38. No. 1. 2. and 4 I have found only the
Teredo bruguieri, delle Chiaje, of which there is a speci-
men in the publie Collection. In MS. No. 3, there is also
the T. palmulata, delle Chiaje, which is eonsidered as very
rare, and Mr. Mamo had not even an example in his pri-
vate Collection, and I think its existenee may be doubted.

(c) The four MSS., besides the Pholas daetylus, L.,
mention the Pholas crispa, Dlaeinville, as rarissuma, of

- te i

whieh only the first species is given in the Collection of the
Library.

(d) MSS. No.land 4 mention only the Erycina renie-
ri, bron.:; MSS. No. 2 and 3 mention also the Eryeina ova-
ta, Philippi, whieh eorrespond to the Ligula boysii and ova-
ia, Montague, in the publie Collection.

(e; MSS.2 and 3 contain three species of Maetra,
namely M. halvacea, Chem.; M. stultorum, L.; M. triangula,
Renieri; while in MSS. No. 1 aud 4 there is also noted as
very rare M. lactea, Lam., which is to be found in the pri-
vate Collection of Mr. Mamo.

(f) MSS. No. 1, 2, and 4, mention only the Bornia
corbuloides, Ph.; in MS. No. 3 are added the B. inflata and
B. seminulum, ejusdem, which are the three Kella of the
publie Collection.

(9) MSs. No. 1, 2, and 4, enumerate four species of
Lucina, the L. pecten, Lam.; L, digitaria, Lam.; L. lactea,
Lamk.; L. fragilis, Ph.; and L. pellucida, Mamo, which last
species, noted as very rare, is described in. MS. No. 4 and
does not exist in the publie Collection.

(h) MSS. No. l and 4 mention six species of Venus and"
five of Cytherea; MS. No. 3, seven species of Venus and five
of Cytherea; whilst in the publie Collection there are eight
species of Venus, viz: V. verrucosa, L.; V gallina, L.; V.
fasciata, Donovan; V.radiata, Broechi; V. undata, Penn.; V.
decussata, L.; V. aurea, Mat. et Rack; and V. lwta, Poli.

(i) MSS. No. 2 and 3 enumerate eight species of
Cardiam, of which there are only seven species in the
Publie Library and in MSS. No. 4 and 5.

(k) There are five species of Area in MSS. No. 1, 2,
and 4, and MS. No. 3 mentions, besides, the Area diluvii.
In the publie Collection there are six species.

(l1) MS. No. 1 mentions seven species of Modiola,
amongst whieh are the M. adriatiea, and M. ligata, which are
noted as discovered by Mr. Mamo. MS. No. 4 mentions
also the Modiola zizyphina, Mamoi, of which the deseription
is given. In the publie collection there are eight species,

(m) In MSS. No. 1, 2, and 4, there are mentioned two

2 qq

species of Mytilus and Pinna, in MS. No. 8 there are three
species of Mytilus and four of Pinna; in the publie Collection
there are four species of Mytilus and four of Pinna.

(n) MSS. No.1, 2, and 4, enumeraie three species of
Lima; MS. No. 3 mentions four species which are found in
the public Collection.

(o0) MSS. No. 1, 2, and 4, in the Class of Pteropoda,
enumerate only the Creseis spinifera, Rang, the Brochus
tracheiformis, Brown, and three species of Hyalzea; in the
pablie Collection and in Mr. Mamo's private one, there are,
besides the same number of species of Hyalea, four species
of Cleodora, including the sub-genus Creseis, and the Coecum
sive Brocus tracheiforme, whieh is considered by Woodward
ard other Conchologists as a Gasteropod.

(pJ '"Phere are as many alterations in the class of Gas-
teropoda. In the family of the Tritoniacea, MSS. 1 and 4
mention only the Thetys fimbria, Auctorum, of which only
one specimen has been caught, and thres species of Doris,
of which one is the D. granulata, Mr. Mamo's. MS. No. à
mentions four species including the D. marmorea, Mr. Ma-
*no's, of which a deseription is given, and amongst the loose
papers I have found a fifth species the D. elephantina, noted
also as discovered by Mr. Mamo, which he deseribed. MS.
No. 2 mentions and describes also the Aeolis capitata, which
is also noted as Mr. Manmo's.

(q) The four M38. enumerate seven species of Bulla; in
the publie Colleetion there are only six.

(r) In MS. No. 8 are mentioned three species of Limax,
of which in the public Colleetion there is only one.

(s) The four MSS. mention sixteen species of Helix;
in the publie Collection there are fifteen species.

(t) In MS. No. 8 there are mentioned nineteen species
of Trochus, six species of Fusus, six species of Murex,
and twelve species of Buccinum; in the publie Collection
there are mentioned eighteen species of Trochus, five of
Fusus, seven of Murex, and ten of Duccinum.

(u) Inthe publie Collection there is the Atlanta Coste,
which is not mentioned in any of the MSS. Ido not deem

it necessary, that I should go on mentioning all the nu-
merous variations existing in the MSS.

9. Finally, from the Memoranda of Mr. Mamo I have
selected many loose papers, which I have bound up together
in this bundle. "They contain many original and interest-
ing observations on the habits, localities, ete., of many of
our Mollusca, which, according to my humble opinion,
deserve to be taken care of. I beg to read a few of these
observations, so that the Society may judge of their
merit.

10. "This is, Mr. President and Gentlemen, the amount
of information whieh I ean offer you with reference to the
MSS. and collection of shells of the late Mr. Mamo.

I beg to conclude this Report by observing that the

Fauna of the Gaulo-Maltese Mollusea is a natural subdivi-
sion of the Mediterranean Fauna, so well known by the

investigations of Poli, Verany, Milne Edwards, Delle Chiaje,
Philippi, Professor Forbes, and Deshayes, and more espe-
cially of that of Sicile, so well fieured and described by
Professors Benoit, Aradas, Maravigna, and others.

On referring to the ** Fauna Molluscorum Regni utriusque*
Sicilie, " we find that Philippi has reckoned about 619 Ma.
rine Mollusea simply on the coast of Sicily, whilst in Mr-
Mamo's Catalogue of Maltese Mollusea we find about 364.

Four years ago a fine specimen of Panopsza aldro-
vandi, Meu, was brought to me at the University by some
Maltese fishermen, taken in the neighbourhood of the Island,
whieh is not in Mr. Mamo's Catalogue. I am strongly
impressed with the opinion that on closer researches, espe-
cially by dredzing, many new species might be added to
the Fauna Gaulo-Melivetana, which will give stronger evi-
denee to the fact, that **while iu its western part, the Me-
diterranean Fauna is identieal with that of the adjacent
Lusitanian eoast, and the number of species diminishes
eastward, it is, however, enriched by a considerable number
of new forms, as yet only known in this part of the Me-
diterranean Fauna" (Woodward). Such additions will per-
haps prove many more accessions than those hitherto known

I MPO

from the Red Sea, showing more evidently a transit, or
link between the Lusitanian and Indo-Paeifie Provinces,
and will] enable us to distinguish more accurately the typical
and endemie species and genera from the aberrant and
expiring forms, throwing much more light upon their specific
and generic areas. I do not dwell on the self-evident expe-
diency of publishing Mr. Mamo's Enumeratio Systematica
Molluscorum with the necessary corrections.

I should only beg to suggest that, in order to com-
plete i& as much as possible, the Fossil Shells found in
the several beds of the Teriiary formation of Malta and
Gozo by Capt. Spratt and others, and specified by Prof.
Forbes and Dr. T. Wright, should be catalogued also
&ecording to their natural place.

In 1859 a Society of English savants through the
Colonial Minister demanded of our local Government all
works on loeal Natural History, and all Meteorological
observations taken in our latitude. I am sure that that Society
would have highly valued Mr. Mamo's work had it been
published.

Il intend to propose to Government the purchase of
the Collection, to form part of the Museum of Natural
History, and to allow the publication of Mr. Mamo's MSS.
at the Government press. If Government comply with
this request, as T have reason to hope, the copies might
be sold on behalf of our infant Society.

P. delieatz, t Nobis. *

1 Amongst Mr. Mamo's loose papers I have found the follow-
ing deseription of the P. delieatze :—

Animale vivacissimo, di corpo pellneido, ovato acuto, superior-
mente alquanto convesso e gibbosetto verso la regione
cervieale, di colore auranziuco; infeiiormente piano,
Capo prodotto in un velo rubieondo, munito presso
l' estremo lembo anteriore di due appendici lineari pa-
piliformi, piuttosto corte. Tentacoli dorsali due verso
il 4to anteriore del corpo, conicc-oblonghi, con nne
rughe oblique eolor di cambagio, alternate con altre
minori. Detti tentacoli sono sostenuti da un gonfiamento
globuliforme di un commune e grosso pedunevlo cervi-
cale, bianchiecio, molto contrattile, istantemente scor-
ciandosi al menomo contatto dei corpi estranei. Due
punti sulfürei ed opachi, anteriore l' uno e posteriore
l' altro, nel detto gonfiamento tra lo due basi dei ten-
tacoli, farebbero supporre in questa specie un trasloca-
mento del sistema visuale in verun' altra parte reperibile.

Le branchie lascian travedere i loro vasellini centrali a fog-
gia di cordoncini tortuosi e ferruginel, i quali biforcati
verso le estrez.itià terminano in punte penicilliformi»

RS Ne

nere. Esse branchie sono disposte in 5-ranghi ellittici
intorno ai lati soperiori del corpo, le piü lunghe mi-
suranti 0,01 m., e decrescenti gradatamente in dimen-
sione verso i margini.

La frega sua consiste in un lungo cordone nel branace e
spiralmente contorto, rosariforme di oviecioli globulari
appianati ai punti di reciproco contatto, opachi e di
color vinaceo.

Ano superiore, destrorso, a foggia di conico tüberculo, a som-
mit? bianea, presso il 3zo posteriore del dorso.

Parte genitale, laterale, mediana, subtuberosa a destra. A-
pertura della bocca inferiormente sotto la base del
velo frontale, ellittieo-longitudinale, armata ai lati di
due mandibule cornee, semifaleate, e seghettate agli
estremi anteriori. Piede ovale-oblongo, rubicondo, lar-
go, semicircolare, e soleato al margine anteriore, po-
s eriormente acuto, e sporgente oltre le estremità delle
sopra seriate papille branchiali dorso-caudali, ove il sao
rubicondo colorito dileguasi in bianco pallido. Tm tinta
fosco-purpurea, tra mezzo alla solea, travedesi quasi
distinto il sistema gastro-ovolare.

La regione dorso-longitudinale nuda vien quasi circoseritta da
due linee lattee, le quali incominciando parallele dalla
regione sopra frontale sino alla base anteriore del comune
peduneolo cervico-tentaeulare, ove s'interrompono, e
quindi dalla posteriore di questo terzo pedunculo scor-
rendo parallele sino al punto mediano dorsale. convergen-
dosi s'uniseono in una sola sopracaudale sino all'estremo
apice del piede.

NB.—Dal non presentare questo mollusco, appartenente alla
sotto familia delle Eolidine, un imponente carattere gene-
rico, anzi che costituire un nuovo genere, s' 6 sti-
mato prudente riferirlo provvisoriamente pel ben della
scienza al Proctonotus dei Sieri. Alder and Hancock sta-
bilito per la Società Rayana di Londra, finché il con-
fronto di qualehe altra specie affine non ci autorizzi a
disporre diversamente.

Ph. melitensis, ! Nobis. *
T Amongst Mr. Mamo's loose papers I have found tho
following diagnosis of Ph. melitensis :—

This new species of Physa was found by mein the reservoir
behind the Plane tree in the Floriana Gardens, on the
12th April, 1856. Several individuals placed in a glass
vessel of water, attached themselves to the edee of the
same, and two days afterwards, deposited a gelatinous:
erystaline, and oblong body, of about the same size as
the mother molluse, very transparent, and containing a
mass of minute, spheroidal, and limpid eegs, like air-
bubbles. Each egg had an opaque, thin elobule on its
surface, of a bright yellow colour. (On the 16th these
globules became discoloured, On the 19th the posterior

m OUO qe

part of the globule bent towards the anterior part, and
took a accelerated and rotary motion inside the
egg. Onthe 80th, some of them separated from the
gelatinous mass, which was reduced to a very thin
membrane, and floated freely on the surface of the
water, showing distinetly the nucleus of the shell, the
white body of the animal, with its two tentacles, and two
very dark eyes.
