MY VERY DEAR FRIEND:—
I have already dedicated one of my volumes of Observations on the Genus
Unio to you; still, as this is the most important of all my works, I cannot resist
the inclination to offer it to you, who have been my lifelong companion, associate,
and friend. For over fifty years we have been united in labors to promote the cause
of Science, by the ties of friendship and the congeniality of tastes and pursuits. In
my particular branch you haye always aided me by your sympathy and advice. All
medical men know what eminent services you have rendered in the advancement of
the healing art. These are claims which induce me to ask you to accept this, the
fourth edition of my Synopsis, which is almost a new work.
Always your constant and sincere friend,
ISAAC LEA.

PREFACE TO FOURTH EDITION.
Ir is now eighteen years since the last edition of this “Synopsis” was published.
The advancement of the knowledge of Natural History has been accelerated during
that period by the labors of many men of science, the younger of whom have
embraced the study with great earnestness and energy. The effect of this progress
has been felt very sensibly in that interesting group of Mollusca which embraces the
Family Unionide. Consequently the additions of species and synonyms have been
largely increased, resulting, in fact, in more than doubling the lists of the last edition.
The labor required for this portion of the work has been very great.
The same principles of arrangement of the tabular system which were used in
the previous editions have been retained in this. After the experience of thirty-four
years since the first edition was issued, I have had no reason to believe that any
better arrangement could be devised in the present state of our knowledge. The
tables have therefore been extended to the present time, and have been so much en-
larged with new matter as almost to entitle the work to be considered a new one.
This has been done with a faithful desire to recognize every fellow-laborer in this
group, and to render to each one full justice. Some may have been omitted, for
want of access to their works—none intentionally.
The present edition is greatly improved and enlarged by additions to the geo-
graphical distribution tables, and by the habitat of each of the species; and the
Index referring to the tables of species and synonymy has had the exact references
fully made to the works where they were originally announced. These two very
important additions to the previous editions will facilitate the use of reference to all
the works on the subject which this “Synopsis” embraces.
B
vi PREFACE TO FOURTH EDITION.
These tables were originally made for my own use. Subsequently I was induced
to print them, and they have now expanded to a large volume. With all the care
which has been bestowed on them, I do not present them as a perfect and complete
work, and I trust that any omissions and errors may be pointed out to me.
The Bibliographical List of the Unconide at the end of the volume will surprise
the general student by its enormous extent, comprising, as it does, about eleven
hundred references, and yet I am perfectly aware that many works will be found to
exist which have never come under my notice.

THE FAMILY OF UNIONIDA.
Some students of the Mollusca have treated the Family Unionide as of little
importance or interest. This has evidently arisen from the fact that they are com-
mon and generally not attractive to the eye as the marine species are. But when
we consider that over 1000 books and papers are inserted in the list herein presented,
we must acknowledge that most of the best writers on Malacology have given space
and attention to the importance of the subject. Deshayes very properly remarks:
“Aussi il est peu de genres dans le grand ensemble des Mollusques qui ait été plus
fréquemment mentionné que celui-ci.”*
And Swainson in his Malacology very properly remarks that “The Unionide, of
all the groups of Dirayrra (Conchifera), is that which contains the greatest modifi-
cations of form; insomuch that it becomes almost impossible, in some of its minor
divisions, to determine which are species and which varieties,” &e.—P. 290.
The following table of arrangement and synonymy was undertaken purely with
the view, and in the hope of clearing away the difficulties which had encumbered
one of the most interesting families of the Mollusca. In this attempt I met, while
pursuing the task, with obstructions and difficulties which I little anticipated at its
commencement. The want of some of the books of reference, and the confusion
which reigned throughout many of them, sometimes presented obstacles which seemed
almost insurmountable. The extensive and admirable library of the Academy of
Natural Sciences of Philadelphia has greatly aided me in this and the previous
editions. In attempting to establish the synonymy, I have endeavored to render the
strictest justice, and if, in any case, it be found that I have failed to do this, it will
be a matter of sincere regret. All corrections will be gratefully acknowledged.

In the following tables there will be found in the Family, 1069 recent species as
admitted, 224 unknown to me or doubtful, and 185 fossil; in all 1476; and the
synonymy according to my views is enormous, being 891.
Of the subgenus Triquetra (Klein),' there are 4 species and 25 synonyms.
Of the subgenus Prisodon (Schumacher),’ 3 species and 13 synonyms.
Of the subgenus Unio (Retzius), there are 833 species in a recent state and 501
synonyms. In addition there are 141 which I have not been able to admit as certain;
of fossil species 169.
Of the subgenus Margaritana (Schumacher), there are 29 admitted species, and
6 which are unknown to me. There are 66 synonyms.
Of the subgenus Plagiodon (Lea), there is 1 species.
Of the subgenus Monocondylwa (D’ Orbigny), there are 26 species, and 4 un-
known tome. There are 27 synonyms.
Of the subgenus Dipsas (Leach), I know of but 2 species, both of which are
recent. There are 20 synonyms.
Of the subgenus Anodonta (Cuvier), there are 148 admitted species, and 68
which are unknown to me. Of fossil species there are 14. Of synonyms there are
189.’
Of the subgenus Columba (Lea), there are 2 species, and 13 synonyms.
Of the subgenus Byssanodonta (D’ Orbigny), 1 species.
Of the subgenus Jridina (Lamarck), there are 4 species, and 3 unknown to me.*
There are 6 synonyms.
Of the subgenus Spatha (Lea), there are 9 species, all recent, and 2 unknown
tome. There are 22 synonyms.
Of the subgenus Mycetopus (D’ Orbigny), there are 8 species, and 8 synonyms.
Most of the distinguished authors who have written on the subject of the division
of this Family, have acknowledged the extreme difficulty they have encountered in
separating it into natural groups. This difficulty is not peculiar to the Unionide.
In most of the Families where a great number of species has been observed, we find

8’ To Anodonta cygnea alone I make 106 synonyms, and I believe that many in my doubtful list will
be found to be mere synonyms to this prolific species, which has been a mine to ambitious species makers.

these species so merging, and, in some of their characters, so fading away into each
other, that we scarcely know how—indeed, in some instances it is impossible—to
make the separation with precision. ‘Natura non facit saltum.” A writer in the
Edinburgh Review, No. 212, p. 494, says some German and French botanists “content
themselves with calling species any collection of individuals which resemble each
other more than they do any other set of individuals, without any limitation to the
degree of resemblance or difference which shall determine whether they belong to
the same or distinct species.”
“But the more rational definition adopted in substance by all the great masters
of the science of the present day is that of ‘a collection of individuals which, by
their resemblance to each other, or by other circumstances, we are induced to believe
are all descended or may have descended from one individual or pair of individuals.’
The various modifications of this definition enumerated by De Candolle consist
chiefly in the more or less detailed enumeration of the other circumstances, such as
hereditary constancy of character, facility of intermixture of breeds,” &e.
In the vegetable kingdom, the same obstructions to a system are encountered.
The observations of Lindley' are so just and philosophic, that I cannot refrain from
quoting them here :—
“Species are created by Nature herself, and remain always the same, in whatever
manner they may be combined: they form the basis of all classification, and are the
only part of it which can be considered absolute. For although, in a natural system,
all other combinations—whether genera, tribes, orders, or by whatever name they
may be known—comprehend species agreeing much more with each other than with
anything else, and haying a positive general resemblance in the majority of their
features, yet no fixed limits can be assigned to any of them; on the contrary, they
pass, by means of various intermediate species, into the other genera, tribes, orders,
&c., to which they are most nearly allied. For this reason, viz., that no fixed limits
can be assigned to orders, genera, &c., we find the ideas about them fluctuating with
the degree of our knowledge; which is the true cause of those changes in the limits
of genera, &c., which persons unacquainted with the subject are apt to consider
arbitrary, but which, in skilful hands, are dependent upon a progressive advance in
the knowledge of science.”
Linnzus defines species thus: “Species tot sunt quot diversas formas ab initio
produxit Infinitum Ens; que forme secundum generationis inditas leges, produxere
plures, at sibi semper similes.”—Phil. Bot., 99, 157.

_e
According to St. Hilaire a species is a collection or succession of individuals
characterized by a combination of distinctive features, the transmission of which is
natural, regular, and indefinite in the existing order of things.”
MM. Ray and Drouet (Revue ef Mag. de Zoologie, 1849) give their views of
what forms a species in the following terms: ‘Généralement on entend, par se mot
(espece), un type d’organisation de forme et d’activité, rigoureusement déterminé,
qui se perpétue successivement par génération directe et une maniére indéfinie avec
la méme constance de caractéres.”"
Milne Edwards’s definition of species, I think, is less clear. He says: “On
donne le nom d’espéce a Ja réunion des individus, qui se reproduisent entre eux avec
les mémes propriétes essentielles.”
Cuvier considered that the fact of the succession and of the constant succession,
constituted alone the validity of the species.
Dr. Morton comprised his view of species as “a primordial organic form.”
Neither of these definitions fulfils my own idea of what forms a species. It
seems to me that a species must be considered to be a primary established law, stamped
with a persistent form (a type), pertaining solely to itself, with the power of suc-
cessively reproducing the same form and none other.
Blainville, in his Manuel de Malacologie, divides the Unionidae (his Sub-Mytilacea)
into Anodonta and Unio, but thinks that species will be found which will make these
to be united.”
Dana’® says “a species corresponds to a specific amount or condition of concentred
Sorce, defined in the act or law of creation.”
Sowerby says: “The difficulty of ascertaining to which genus of Lamarckian
Naiades certain species belong, arises from the very general similarity of form,” &e. ;
“in fact, an examination of a sufficient number of species will prove that no depend-
ence can be placed upon the characters by which authors usually attempt to discrim-
inate between these genera, and that the transition from one to another is so gradual
in some instances, and so strongly marked in others, that it is not surprising that
authors, who, having only met with certain species, and not being aware of such
intermediate links, should have considered them as the types of new genera.”* And
further: “We think we have already said enough to prove that, unless it be thought
1M. Drouet, in his Etudes sur les Nayades de la France, 1854, has given valuable observations on
the anatomy, function, diagnosis, &c. of Anodonta.

wise to elevate each of the peculiar sorts we have mentioned, and many more, into
distinct genera, it will be positively necessary to unite them altogether under one
generic appellation.”
Deshayes, in his edition of Lamarck’s Animaux sans Vertebres, says it is impos-
sible to separate the genera of the Unionide. ‘ Nous pourrions prendre pour exemple
celui des genres qui est consideré comme l’un des mieux caractérisés. Le genre
Symphynote (Lea) est fondé sur ce caractére remarquable que les deux valves sont
soudées entre elles le long du bord supérieur,” ete. ‘Nous concluons que tout ce
grand ensemble ne peut et ne doit former qu’un seul genre constituant a lui seul la
famille des Nayades.”'
In his admirable work Zraité Elémentaire de Conchyliologie, not yet finished, he
continues to consider that his twenty-fifth Family, Nayades, is filled by one genus,
viz., Unio of Retzius. He makes, however, four divisions, which, he says,” “différe
a peine de celle de M. Lea.”

It might be expected that some attempt of the application of M’Leay’s circular
system should be made in regard to this family. Swainson says that “the progres-
sion of every natural series is in a circle.’ In my attempts to verify this, I have
1 Vol. vi. p. 526.—I shall be excused in taking this opportunity to correct an erroneous impression
on the mind of M. Deshayes. He says that I was not able to examine the collection of the Museum of
Paris. ‘ Malgré cette imperfection qu’il ne pouvait empécher, le travail de M. Lea se recommende A
Vattention des naturalistes par ces observations judicieuses, des descriptions exactes,” etc. It would be
strange, indeed, if, after spending so many years in the study of this family, that I should neglect, while
in Paris, to see the collections from which Lamarck made so many descriptions. I was frequently at the
Museum, and on one particular occasion, by appointment of MM. Blainville and Ferussac, arranged, in
the presence of these and other gentlemen, all the species of the Unionide that were in the Museum, and
named them; and also presented to the Museum about fifteen species which were new to that great
national institution. I also did the same thing for Baron Ferussac, having designated every specimen in
his cabinet belonging to this family.

not been successful. That the same idea exists in the construction of species is
evident through a great number, but that this idea is returned to the point at which
it commenced I am not prepared to admit. The arrangement of the system adopted
in this Synopsis, whatever may be said to the contrary, is eminently natural as regards
the exo-skeleton or shelly covering of the included soft parts. Although I have
examined critically and published descriptions of the soft parts of 254 species of this
family, and often dissected 50 to 100 of the same species, I cannot see, as yet, any useful
division that could satisfy the student or the adept, which can be made by systematic
difference in the organic forms of the soft parts. With a knowledge of the soft
parts of about only a fourth part of the family, is it not unwise to attempt a division
for the whole? And again, will it not be a very long time before it will be possible
to obtain the complete animal of most of the species? Some of them perhaps
never will be obtained by the American or European Malacologist. I am satisfied
that eventually, when we shall become sufficiently acquainted with the soft parts
of most of the Unionide, the best division into genera will be founded on the
diverse forms of the branchial uter?. I have now examined carefully 254 species,
mostly with charged uteri, and I have come to the conclusion that any safe division,
founded on the characters of the functional soft parts, must be based on this very
important organ, which shows so distinct and varied a conformation, often involving,
as it does, the form of the massive envelope.
In regard to the making of species a few remarks may be made here. That
there has been great abuse of it there can be no doubt. Think of the nearly 250
synonyms for the seven or eight species of the Family Unionide living in Europe!
Many very able writers have deprecated this folly and ignorance, but it still goes on.
In the United States we have such an extraordinary development of this form of
shell life, that many European writers find it difficult to give us credit for our real
disposition—at least I speak for myself—of keeping down our species as much as
possible. The nomenclature is becoming truly embarrassing, and there seems to be
no avoidance of it. We have by no means exhausted the discoveries of these forms
in Georgia, Alabama, and Mississippi, which States seem to be, and particularly
Georgia, the centre of this form of Malacological life." No species has ever been
described by me without the greatest care and all examination used that was possible.
When not well satisfied of distinctive characters, I have laid the specimen aside in
hopes of better light, and I have by me now many of which I am uncertain as
1'The late Bishop Elliott, who did so much to develop the Unionide of Georgia, observed to me in
one of his letters, that almost every stream seemed to afford him new species.

to their identity, and therefore I hesitate. Some of these I have had for more than
twenty years.’ It should be remembered that many of the diagnoses of my new
species were made from single specimens, and these sometimes imperfect. The various
aspects and the differences of the characters of the old and young as well as that of
males and females, are often very imperfect, and necessarily therefore some are omit-
ted. The important character of the undulations of the beaks is often omitted on
account of the imperfection of the part.
Too much stress cannot be laid on the importance of keeping down the species
in all branches of Zoology. Prof. Owen has well remarked that “the coining of
names for things glanced at and imperfectly understood, the falsification of signs
without due comprehension of the thing signified, becomes a hindrance instead of a
furtherance of true knowledge.” And Prof. Carpenter, in one of his lectures in
1859, said “there are too many who are far too ready to establish new species upon
variations of the most trivial character, without taking the pains of establishing the
value of these differences, by ascertaining their constancy through an extensive
series of individuals; thus, as was well said by the late Prince of Canino, ‘deserib-
ing specimens instead of species,’ and burdening science not only with a useless
nomenclature, but with a mass of false assertions. It should be borne in mind that
every one who thus makes a bad species is really doing a detriment to science, while
every one who proves the identity of a species, previously accounted distinct, is
contributing towards its simplification, and is therefore one of its truest benefactors.”
Dr. Arnott, in Proceedings of the Royal Society of Edinburgh, very forcibly says that
“to indicate many apparently new species, is the work of an hour; to establish one
on a sure foundation, is sometimes the labor of months or years.”
To form a systematic, and, so far as possible, a natural arrangement of this
family, has long occupied my serious attention. :
I was, from my first knowledge of the Family, struck with the very different
aspect of the winged species, and, taking the hint of Lamarck,’ I thought that an
important division could be made by separating the connate from the free shells, and
proposed the name of Symphynota for such as were connate. I was not satisfied at
that time in separating a genus of this family by a character differing from that of
the teeth, but presumed that the family would be taken up by some one, if not by
myself, and that the first division of it would be symphynote and non-symphynote
1 The observation of alate French writer that not more than three in one hundred of my species
will stand, is too flippant to need much notice. Time will prove that very few will be eliminated.

Xvi SYNOPSIS OF
Unionide. The numerous new species which have been made known since, have
satisfied me that this character cannot be so extensively and usefully applied as I
then thought it could, and that it is not, in fact, free from the same objection which
pervades so many generic characters as adopted by the most intelligent naturalists,
viz., that perfect fading and mingling of character which interferes with all the sys-
tems yet formed.
Sowerby, after examining into the propriety of dividing the Family into genera,
came to the conclusion of keeping but one genus, viz., Unio: this he divided into A
without teeth, B with teeth. These he subdivided into winged and not winged.
Another subdivision followed these, on the presence, form, and absence of teeth.
There is evidently much merit in this division, but it is not perfect; nor ought we
to expect perfection, I believe, in any system.
Ferussac informed me, when in Paris, that he proposed to consider the Family
Nayades to consist of one genus, Margaritifera, which genus he divides into the
following subgenera: 1. Anodonta; 2. Iridina; 3. Dipsas; 4. Triquetra;' 5. Alas-
modonta ; 6. Unio.
Swainson, in his Walacology, divides the Nayades of Lamarck into several sub-
Families and a great number of genera, which do not seem to me to possess charac-
teristics sufficiently different to be adopted. They are as follows :—
Unio. Lam., represented by Unio sulcatus. Lea.

' T have never been able to examine this rare work until recently, it being now in the Library of the
Academy of Natural Sciences. The establishment of the genus Unio has been usually given, by French
authors, to Bruguiere, but the English and German writers give it to Retzius so universally, that I have
followed them. The author of this dissertation would appear from the title-page to be L. M. Philipsson;
Retzius being the presiding officer of the institution. But it is understood to be a fact that papers writ-
ten by officers of the Universities in Germany have been sometimes published under the names of students
as Theses, and it is said that this is one of such cases.
* Ido not see any reason for throwing out Jridina and taking in its place the name of Plezodon,
which was unnecessarily given to a shell well known and figured long before, and described both generic-
ally and specifically, viz., the Iridina ovata, Swain.

Prof. Troschel, in Wiegmann’s Archives, vol. xiii. 1847, divides the family, by
their anatomical structure, into nine genera, viz. :—
Unio (Retzius). The mouth lips are wider than long, united as far as the middle on the pos-
terior margin. The margin of the mantle entirely open; the outer branchia united to the mantle
to its very extremity; the inner branchia not united to the foot; the foot is tongue-shaped, thick,
somewhat produced anteriorly. (Unio twmidus, Retz., and Unio Hopetonensis, Lea.)
MARGARITANA (Schumacher). (Alasmodonta, Say.) The mouth lips are wider than long, united
along two-thirds of the posterior margin. The mantle entirely open; the outer branchia is free
posteriorly, and lies in a fold of the mantle; the interior branchia is united to the foot anteriorly,
but along the greater part of the foot it is free; the foot is tongue-shaped, somewhat produced
anteriorly. (Mya margaritifera, Lin.,) Tab. 6, Fig. 1.
Hyria (Lam.) The month lips as wide as long, not united. The mantle margin inferiorly is
open, posteriorly closed, so as to make a branchial and anal aperture. The outer branchia united
to the mantle to its extremity; the interior branchia is united to the foot; the foot tongue-shaped,
thick, somewhat produced anteriorly. (H. syrmatophora, Lam.,) Tab. 6, Fig. 3.
CasTALIA (Lam.). The mouth lips a little wider than long. The margin of the mantle infe-
riorly is open, posteriorly so united that the branchial and anal apertures are closed; the branchial
aperture is surrounded with cirri; the anal aperture smooth; the outer branchia united to the
mantle all the way to its extremity; the inner branchia———(?); the foot tongue-shaped, thick,
somewhat produced anteriorly. D’Orbigny, Voy., &. (Castalia ambigua, Lam.)

IrrpinA (Lam.). Mouth lips longer than wide, not united; mantle margin united as far as the
foot, so that the branchial and anal apertures are closed; the outer branchia united to the mantle
as far as its extremity; the inner branchia entirely united to the foot; foot thick, tongue-shaped,
somewhat produced anteriorly. (J. cxlestis, Lea.)
SpatHa (Lea). The mouth lips are longer than wide, and not united. The mantle margin is
closed behind, so that the branchial and anal apertures are closed; on the under margin the mantle
is entirely open; the outer branchia is united to the mantle all the way to its extremity; the inner
is not united to the foot; the foot is thick, tongue-shaped, somewhat produced anteriorly. (S. rubens,
Lea,) Tab. 6, Fig. 2.
Myceropus (D’Orbigny). The mouth lips longer than wide; the mantle margin is open to the
anal aperture, which is closed; the outer branchia is entirely united, or grown together; the inner
(?); the foot is very much produced and widened into a knob. (JL. solentiformis, D’Orb.)
In The Shells of New England, by W. Stimpson, Boston (1851), he states that,
in the MSS. of Prof. Agassiz, the following divisions into genera are made (of the
New England species) on anatomical differences, viz.:—
Unio, Retzius, emend. Gills free from the abdominal sac, their posterior extremity attached
to the mantle; eggs, in the female, filling the whole extent of the outer gill; mantle fringed at
both siphonal openings. (Unio complanatus, Lea.)
HuryNEA, Rafinesque, emend. Gills attached to the abdominal sac, leaving no communication
between the pedal and the upper gill cavities; eggs received in the sacs of the posterior part of the
outer gill; mantle fringed at the posterior half of its ventral edge, and at the branchial and anal
siphons. (Unio prelongus, Bar.)
LAmpsIuis, Raf., emend. Gills attached; eggs in the posterior part of the outer gill; mantle
fringed at both siphonal openings, und having fleshy thickenings and processes at its posterior
ventral edge. (Unio radiatus, Lam.)
MerapTerRA, Raf, emend. Gills attached; eggs in posterior part of gill; a broad expansion
of mantle upwards; superanal opening long; both siphonal openings fringed. ( Unio alatus, Say.)

The very uncertain characters by which Prof. Agassiz proposed to divide this
Family induced me to make notes of many species in which the anatomy did not
seem to me to accord with his views. His principal character is the opening or
closing of the pedal and upper gill cavities. “Gills free from abdominal sae,” and
“Gills attached to abdominal sac.’ Another important character is the possession

or absence of “fringes on the siphonal openings.” I have frequently observed, in
different individuals of the same species, that this condition—freedom and attachment—
was found. It does not, therefore, seem to be worthy of a specific difference, much
less a generic one. Thus in five large perfect specimens of U. multiplicatus' (nobis),
T found three to be united the whole length of the branchia, while two were opened
for a short distance.” In U. Novi-EHboract some were attached and some free. U.
Berlandierii has branchie free and not free. -Alasmodonta marginata, as emended
by Prof. A.: “Gills attached to abdominal sac.” Six specimens from Mohawk
River, N. Y. I found to be all more or less open.
As regards the generic character of Unio emended, the “mantle fringed at both
siphonal openings.” I found the following Uniones without fringe (papille) on the
anal opening, viz.: triangularis, cylindricus, pressus, ligamentinus, levissimus, verru-
cosus, metanevra, lacrymosus, dehiscens, and some others. The following have slight
crenulations on the anal opening, viz.: multiradiatus, rectus, retusus, trroratus, ovatus,
purpuratus, asper, declivis. The generic character of Anodonta, “anal opening not
fringed.” The An. Ferussaciana has papille on the anal opening.’ A. Oregonensis
and A. fragilis have crenulations on the anal opening.
Complanaria, Swain, emended: Alasmodonta rugosa, Bar. Prof. A. says:
“oth siphonal openings fringed.” Specimens from Mohawk, N. Y., had not the
anal opening fringed.
Subsequently to the publication by Dr. Stimpson of the MS. diagnoses of Prof.
Agassiz, he in Archiv fiir Naturgeschichte, in 1852, divides the “Najades” into two
large groups :—
First Group has exterior gills joined the whole length of the foot, having no direct communi-
cation between the lower free cavity and the upper portion, as in U. Sowerbyanus, triangularis, &e.
Second Group. Those which have a free communication between the cavity of the gills and the
lower cavity of the belly, as in “Unio irroratus, U. lineolatus, Raf.”
The genera of the First Division are:—
1. Dysnomia. Ag.. . . foliatus. Hild, and perplexus. Lea.
2. Scalenaria. Raf. (Ag.) sulcatus. Lea.
8. Truncilla. Raf. (Ag.) triangularis. Bar. and arcaformis. Lea,
4. Lampsilis. Raf.. . . radiatus.
5. Canthyria. Swain.. . spinosus. Lea.
1 Two very remarkable characters of some species of Unio seem not to have been noticed by Prof.
Agassiz: rubiginosus, Kleinianus, multiplicatus, and subrotundus have all the four leaves of the branchiz
pervaded by the uterus, and the first and last have red ova.

In these generic divisions, by D’Orbigny, Troschel, and Agassiz—all founded
on anatomical structure—it will be observed that they do not differ essentially in
their modes of division; and I do not hesitate to express the opinion that our know-
ledge of the structural differences of the soft parts of these animals is not yet suffi-
ciently advanced to found a perfect or permanent system. That such a one would
be instituted I have not doubted, and I so expressed myself in 1838, in a note on
Anodonta Blainvilliana (nobis), in my Synopsis, 2d ed. p. 31,’ and I trust that the
surviving able physiologists whom I have cited above, will continue to give their
labors to an investigation which cannot but produce rich results; but I am disposed
to think that, until malacologists have examined carefully the soft parts of most of
1 Prof. Agassiz says that Al. arcuata, Bar. and Marg. margaritifera, Shwm. differ, in which I do not
agree with him.
* Aware of the great importance of a knowledge of the soft parts of the species of this family, some of
which present very different and well-marked characteristics, I have since the publication of the 2d and 3d
editions given much time and laborious attention to their careful dissection and diagnoses, sometimes
examining more than a hundred individuals of a species. These descriptions of the soft parts have been
published in various papers in the Trans. Am. Ph. Soe. and Jl. Acad. Na. Sci., and in my Observations
on the Subgenus Unio, vols. 1, 2, 6, 7, 8,9, 10,11, and 12. These descriptions consist of the Subgenus
Unio, 211; Margaritana, 14; Anodonta, 26; Monocondylea, 2; Mycetopus, 1—in all, the soft parts of 254
species. Many embryonic forms, which have also had my particular attention, and which present such
diverse and peculiar forms, have been described and figured by me in the Jl. Acad. Na. Sci., vols. iv. and
vi., and Obs. v. 6 and 12, so far as I have been able to obtain them.
Very recently I have received from Dr. F. A. Forel, of Morges, Switzerland, his very able Memoir*
on the development of the Unionide. The anatomy of the embryos, with the illustrations, is worthy of
great praise, and cannot fail to be appreciated as an important advance in this direction.

XXLV SYNOPSIS OF
the existing numerous species—the exo-skeletons' (so to call them) of which have
only come under our notice—the facilities which a good system ought to afford can-
not be reaped by a partial anatomical knowledge, which does not now embrace,
probably, one-fifth of the ascertained species of the family. Besides this, I am not
at all disposed to think that we can entirely dispense with the aid we find in the
various characters of the exo-skelctons, in making our sub-groups. They often, in
fact, afford striking and obvious differences, which the eye schooled with but little
experience can with facility and certainty detect, and which, if happily grouped by
an experienced eye, may greatly aid the student. These considerations have induced
me still to retain nearly the same divisions in this which I used in the third edition,
with a few additional divisions.
Messrs. H. and A. Adams, in The Genera of Recent Molluses, vol. ii. 1858, adopt
the following Subgenera of Unio:—
Banosta. Raf. Naidea. Swain.
Obovaria. Raf. Nida. Swain.
Hyridella. Swain. Lampsilis. Raf.
Canthyria. Swain. Iridea. Swain.
Rotundaria. Raf. Quadrula. Raf.
Diplodon. Spix. Dysnomia. Agass.
Metaptera. Raf.
In vol. iii. of the Trans. Am. Phil. Soc., p. 898, Mr. Nicklin expressed the opinion
“that the seven genera, now referred to the Family of Unionide, are founded in arti-
ficial distinctions, and not in nature; and that, in fact, the family contains but one
genus.”
In consequence of the enormous extent to which the Family Unionide is expanded,
it is absolutely necessary to establish many groups and sub-groups, so as to make a
systematic arrangement accessible to the student of this branch of zoology. I there-
fore divide the family into two genera, Margaron’ and Platiris. The first is divided
into ten subgenera, and the latter into three subgenera. These are again divided
* Forming the calcareous coverings and fulera for muscular fibres, as well as protection from exterior
forces.
? The entire uncertainty of the divisions of Mr. Rafinesque, or their multiplied, useless, and incom-
prehensible groups, are not deemed important to insert here. Nor the synoptical tables of Mr. Conrad,
which differ so much from each other, the last being founded very much on that of Rafinesque.
° In the second edition, I proposed the name of Margarita, but, this name being pre-occupied by Dr.
Leach for a genus separated from Yurbo, I substituted in the third edition that of Margaron (uapyapoy,
Unio).
THGH Ey ASME Lys) (OsE SUeNEvOEN TD ean XXV
into symphynote and non-symphynote, which groups are again divided into plicate,
nodulous, spinous, suleate and smooth shells. Hach of these is subdivided into
nine groups dependent on the outline of the plane of the valve, viz., into quadrate,
triangular, oblique, oval, oblong, subrotund, wide, obovate, and arcuate, as in the
following table :—
1 In regard to priority of claims of date, I have never considered that the old rule of dating the
discovery of a species at the time it was read before a scientific society, should have been altered as it
has been by many bodies of science. My experience has satisfied me that justice to the discoverer could
best be rendered by retaining the old rule. In all cases I adhere to this, and date my papers in accord-
ance, and accord the same to others. It is the custom with the two leading societies of Europe, the
French Academy and the Royal Society, as well as the American Philosophical Society in this country,
the Asiatic Society of Bengal,and others. The Report of the Committee of the British Association, Aug
1856, recommends a Catalogue of European and American Philosophical Memoirs to be made, and, where
published in Transactions, the date of reading to be stated. Under the cover of the rule of printed issue,
Mr. Conrad* and Mr. W. G. Binney have misstated dates of many of my species, which dates are erro-
neous even under the rule of printed issue. Thus Mr. Binney, in the publications of the “Smithsonian
Collections,” Bibliography of North American Conchology, Part I. 1863, gives the dates which he finds in
the imprint of a volume, although he knew that parts of the volume were issued printed, perhaps years
before. I therefore protest against the manifest errors which arise from such proceeding. This is in
accordance with the fact that while he published in this volume the erroneous dates of Mr. Conrad’s Syn-
opsis regarding my species of Unionide, he omitted my tables of rectification of these dates, which of
course rendered the Bibliography incomplete and was an act of injustice to the science of the country.
When the omission was pointed out by me to Prof. Henry, Sec. of the Smithsonian Institution, he
kindly promised it should be remedied in an appendix.
Tn the following year, when Part II. came out, in Appendix to Part II. Mr. Binney inserted a s¢mple
list of little more than a page of my species without a single date! 'This list was a mere mockery, and
the observation that “Mr. Lea having requested that the whole of his ‘Rectification’ should be published,
I add a list of the species to which he refers in that paper, in addition to those quoted by me on p. 384,
Part I.” is not the fact.— I never requested Prof. Henry to have the whole of my ‘ Rectification” published
in this Bibliography; I wished only the tables of species with dates of the time read and the time issued
printed, and I sent a copy marked as requested by Prof. Henry, to be so inserted. Mr. Binney had given
Mr. Conrad over eight pages, double column, for his Synopsis, and to my “Rectification” four lines!!
Addressing Prof. Henry on this second wrong, he requested another marked copy with the tables I wished
to be inserted, and in Appendix iv. 1866, under his own name, I obtained this very slow partzal justice.
* Mr. Conrad in his ‘‘ Catalogue of the Eocene and Oligocene Testacea of the United States,” in Am. Jl. of Scz.,
vol. i., makes some of my species synonyms to his, by dating mine in ‘‘1834,’’ while my ‘‘ Contributions to Geology”’
was on sale about the first of Dec. 1833, and has the imprint of 1833! It had an extended notice in the Jan. No. follow-
ing of Silliman’s Journal.
+ ‘*Isend you at once the part of my ‘Rectification’ which should have been inserted to neutralize the poison of
the ‘Synopsis’ of Mr. Conrad.”’—xtract of Letter of I. Lea to Prof. Henry, Noy. 20, 1863.
And in my letter of Feb. 8, 1866, to Prof. Baird, who was attending to the ** Smithsonian Collections,” T said, ** You
must be aware that I never requested to have my ‘ Rectification reprinted.’ It was only these important tables of facts
and not the argument,’ &c.
Mr. Tryon, in his excellent ‘‘ American Journal of Conchology,”’ vol. i. p. 270, commenting on these errors of dates
says, ‘‘ Mr. Lea, however, immediately proved the time of publication (printed) of some of these parts of the volumes
of Transactions, and, consequently, the prior date of certain of his species by evidence which has never been questioned.
Yet Mr. Binney has not deemed it advisable even to mention the dates stated by Mr. Lea, exceptin regard to four species
only, and thus those who in future times depend, as they certainly will, on the Bibliography, for the synonymy of these
species, will be misled into the perpetration of a wrong.”

Vv Amér. Mérid.), was observed by him in the Rio Parana above Corrientes. It resembles an Anodonta,
but remains always attached by a byssus proceeding from the foot. It has anterior and posterior adductor
muscles. The interior is not nacrée. The inner posterior portion is violet-brown; the anterior is white.
It is attached to rocks below low-water mark. It has not been as well observed in regard to its habits and
anatomy as it deserves to be. M. D’Orbigny places it among the Unionide, in which family it no doubt
will be found properly to belong by its anatomical structure. Unfortunately the soft parts were destroyed
before an examination was made. The genera Ltheria, Mulleria (Acosta, D’Orb.), Galatea, Cyclas, and
Dreissena, also inhabit fresh water, and have their affinities.

XXVIil SYNOPSIS OF
In regarding these outlines, the shell is supposed to be lying on its side with the
ligament furthest removed from the observer, and the beak to the right of it. The
base will, of course, be nearest to him, and the anterior margin will be to his right,
while the posterior margin will be to his left. This is my mode of arranging my
whole cabinet, which contains over 9500 specimens of this family, each differing in
sex, age, some characteristic, or in geographical distribution.
In attempting to make a complete synopsis of the Unionide, much labor has
necessarily been expended. Ido not present this as a perfect work, but it has been
made as nearly so as the opportunities in my possession permitted. Errors may have
arisen from two sources: first, default of judgment; second, from accident, owing to
the mass of research necessary to accomplish the object, considering the crude state
the subject has been in. I shall be most agreeably disappointed if there be not parts
pointed out as erroneous which are substantially correct. It will be observed that
the works of M. Rafinesque are but little quoted. This has arisen from the utter
impossibility of satisfying myself as to his species, causing me at an early period to
abandon the task of making out his very imperfect descriptions. His own discrep-
ancy in the names sent to Ferussac,' and those which are attached to specimens here,
together with the want of accordance in the tables made out by his friends, have
induced me to regard his claims as being too slender to rely upon the decisions, so
contradictory, of the several parties, in the absence of the individual specimens noted.
In the absence of these specimens, which no naturalist has, I believe, ever seen but
the Professor, I feel myself compelled to prefer other authorities, which are now
almost universally received by our malacologists. I am the more fortified in this
conclusion, when I see that Mr. Conrad, his most ardent advocate, acknowledges that
he (Rafinesque) has made six species from a single one;’ and the absurdity is still
stronger when we turn to M. Rafinesque’s monograph, and find that this single species
has furnished several genera, and is placed, in fact, in two different sub-families 111
How far M. Rafinesque ought to be considered worthy of authority at home and
abroad may be understood by the opinions of the following distinguished writers.
The late Dr. Binney, in his admirable work on “Terrestrial Mollusques of the
United States,” says the papers of Rafinesque “are not deemed worthy of any con-

résulté une difficulté inextricable pour la détermination de ses especes, et pour pouvoir établir une syno-
nymie exacte entre lui et les autres qui, depuis, se sont occupés des Mulettes.”— Magasin de Zoologie,

sideration:” vol. i. p. 36: “that they are considered to be destitute of authority, and
entirely unworthy of notice.” p. 48.
Prof. Asa Gray considered Mr. R. as entirely unworthy of authority, stating that
“half his genera and species do not exist at present,” and that he described in
“Natural History style twelve new species of thunder and lightning.”—Am. Jl. Sc7.,
1841.
Deshayes, Traité B lémentaire, vol. ii. p. 198, says that Mr. R. has fallen into a
deplorable excess, inspiring no confidence, giving descriptions of that which he did
not know.
The following note is from one of the very best of authorities among recent
writers :—
“Tt is much to be regretted that some modern naturalists have tried to find out and bring into use
the obseure genera of Risso and the worthless fabrications of Montfort and Rafinesque, which had better
have remained unknown.”— Woodward’s Rudimentary Treatise, p. 136.
Did any naturalist ever believe in Mr. R.’s Tremesia patteloides, a trivalve shell
of the Ohio river? (Monographie, p. 54, pl. 82, f. 22 and 24,in An. Gén. des Set.
Phys. & Bruxelles, 1820) the three valves of which, with the soft parts, he describes
and figures in three views without pretending to have seen it, as he stated in the
Am. Monthly Mag. ; and that he described it from the information of Mr. Audubon,
who, it is believed, practised some joke upon him at Louisville, as appears in Mr.
Audubon’s Memoirs.
In regard to the Catalogue published last year by Baron Ferussac, in which he
gives precedence to many of Mr. Rafinesque’s names, it must be remembered that this
has been done on the authority of others, and not from his inspection of the specimens
themselves. Had he known the manner in which these claims had been brought for-
ward, he certainly would have admitted them with doubt, if he admitted them at all.
The observation of Prof. Agassiz in Archiv fiir Naturgeschichte, 1852, that “if
the American Naturalists had followed Rafinesque’s track, instead of despising him
we should have gained a good while ago a treasure of important additions to the
anatomy of this family,” will surprise most students of American Natural History.
I am not aware that a single cotemporary writer considered him worthy of authority
or reliance of any kind. I so far disagree from Prof. Agassiz that I believe with
some of our most distinguished naturalists that if Mr. Rafinesque had never written
a word on the subject of American Malacology and other branches of Natural History,
we should have been more advanced than we are now; for even Prof. Agassiz himself
has been troubled to exhume Mr. Rafinesque’s genera, as he states in this paper that
H
xxx SYNOPSIS (OR Hn RANE Ye (OK TU NetOp EAT.
the genera Amblema and Ellipsaria “are good for nothing,” that we can neither make
use of these names nor of his Obliquaria : and further, “there are several other genera
of Mr. Rafinesque’s, indeed, that I know not how to dispose of.”! If Prof. A. finds it
so difficult to follow Mr. Rafinesque’s tracks, how can he blame the early American
naturalists, who had so much less light than himself?’ The prejudice expressed
above against “American Naturalists” is not warranted, and the whole career of the
unfortunate Mr. Rafinesque in this country was not such as to excite the sympathy
and the universal good feeling which existed among our early naturalists. When I
commenced the study of our Fresh Water Shells I found that my predecessors, Messrs.
Say and Barnes, did not credit him with a single species; they could not be satisfied
of the identity of one. Other naturalists—Griffith, Hyde, Peale, Green, and Stew-
art—thought three or four could be relied on, and these I adopted. I believe I was
the first writer to allow him one. I studied his works faithfully, without prejudice,
and certainly without profit, losing much time ineffectually.
In 1836 the Ohio naturalists, Dr. Hildreth, Dr. Kirtland, Dr. Ward, Judge
Tappan, Mr. Buchanan and Mr. Clark, after much consultation, made out a list for
western naturalists to be finally adopted. They made out 119 species, of which they
gave Mr. Rafinesque one, and that with doubt.
Subsequently, when jealousies arose, Mr. Say and Mr. Conrad in 1834 published
synoptical tables with the specimens of the North American Unionide before them,
which it was said Mr. Rafinesque had labelled, but they could not with this light
give any certainty to Mr. R.’s species, as these tables differ so much as to types and
synonyms as to neutralize what their authorities might otherwise have been. The
animus of Mr. Say’s synopsis may be understood in the fact that in it he did not
give me a single species! while Mr. Conrad gave me twenty, and those evidently
with reluctance.
The first entry of Mr. Conrad’s Synopsis is U. abruptus, Say=cyclips, Raf., and
calendis, Raf. Mr. Say’s Synopsis does not claim this species, nor does he enter Mr.
Rafinesque’s two names at all. Mr. Conrad gives ater, Lea=lugubris, Say. Mr. Say
reverses this, and makes my ater the synonym. Mr. Conrad gives cyphius, Raf.=
cicatricosus, Say. While Mr. Say claims for himself cécatricosus as a type, &c. &e.
1 Prof. Leidy has been more fortunate in another line of investigation, as he has shown in ‘‘Hatinct
Mammalia of North America,” p. 376; that he found, in the examination of Mr. Rafinesque’s fossil
mammals that he had made three fossil genera from the bones of the common recent deer, Cervus Vir-
ginianus.

? The shell known to zoologists generally as Hyria corrugata, Lam., was long before placed by Klein
under the generic name of Triquetra (Tentamen Methodi, 1753, p. 135, Pl. 9, Fig. 36), and Ferussac
adopted it, very properly, in preference to Hyria. In my former editions, I placed Hyria in the subgenus
Unio, but the animal has been found to possess two syphons, which ought, with other obvious differences,
to separate it from Unio (Gray, Annals of Nat. Hist., Dec. 1840). Troschel, in Wiegmann’s Archives,
describes the soft parts and the cicatrices. The cicatrices in the H. corrugata, he says, differ; which is
true, as in the genus Hyria there exists usually a very well marked cicatrix, which is deeply impressed,
distinct, and lies over the great anterior adductor cicatrix. He also says that the Unio delphinus belongs
to this genus, as well as a new shell, Hyria humilis, from Guiana, described by him.
* The figure of Blainville, pl. 67, fig. 1, is evidently the smooth Triquetra, and no doubt is subviridis.
’ Mr. Gray thinks this is a “perfectly distinct species.’’ I have never seen the shell, and feel too
much in doubt to insert it as such.

1 Schumacher, in his Nouveau Systéme, 1817, p. 138, formed the genus Prisodon, in which he included
the two now well known shells Hyria syrmatophorus and Castalia ambigua. His name for the first can-
not be applied, as Klein, in 1753, preoccupied this genus by naming it Triquetra. Therefore it must be
applied to Castalia, which name was given to the same shell by Lamarck in 1819. Mr. Gray, in his
“Genera,” gives Schumacher priority in the name of Prisodon, in which he is perfectly correct.
_ ? I owe to the kindness of M. D’Orbigny specimens of this and inflata. I regret, however, that I
am compelled to differ in opinion with this distinguished naturalist, believing, as I do, that there have
been as yet observed but three species of Prisodon (Lamarck’s Castalia).
$JT have all these five forms of M. Hupé’s in my collection, and have always esteemed them the
truncatus Schum.
* T have seen no specimen, nor has M. Hidalgo given a figure; but I suspect that Crossiana is a more
perfect specimen of ambigua than usual. I may, however, be entirely mistaken in this opinion.
5 In my second edition, p. 22, this shell was placed among the Uniones, with a note as to its analogues
and its habitat. On my visit to Vienna in 1853, I found, in the Imperial cabinet, the right and left valves
of two individuals under the name of Chama plumbea Mihlfeld, but then labelled Unio plumbeus. Having
serrated teeth, it properly belongs here. See Proc. Acad. Nat. Sci., vol. 6, p. 368.

to give preference to Mr. Barnes’s name, by which the shell has been universally known among our con-
chologists.

1 Dr. Gould (Boston Nat. Hist. Soc., April, 1847) says it resembles Margaritana Vondembushiana,
Lea, now transferred to Monocondylwa, D’Orb.
*In the Proceedings of the Am. Phil. Soc., vol. ii. p. 237, I changed compressus into pressus, the
former name having been used by Sowerby for a fossil species.
’ Where did Barnes describe “ Unio Alasmodontinus, Barnes,” as quoted by Agassiz?
“Fresh water and land shells of Vermont.” His variety plebeius does not seem to me to differ.
My brother, T. G. Lea, stated to me that he thought the U. pressus properly belonged to the genus Mar-
garitana, and that the charged ovisacs were like those of MZ. complanata. In all the fifteen which he
found during several years, the ovisacs were charged. I have since examined a female, and find this
species has in the soft parts other characters like Margaritana, but not completely so, and having true
lateral teeth, it must be placed with Unio.
5 When I described the multiplicatus in 1830, I had had several specimens for two or three years,
and was not aware that Mr. Say had published a shell under the name of heros, which he subsequently
abandoned as the undulatus of Barnes; but in 1834 reclaimed as heros. The figure of Mr. Say in Ame-
rican Conch., pl. 16, is certainly not U. undulatus, Bar., as he supposed. It is undoubtedly my m ultipli-
catus, as a comparison of the two figures will prove. Mr. Say refers to Barnes’s fig., Am. Jl. of Science,
vol. vi. pl. 2, as being the same with this; but a comparison will show that they are not alike in outline,
in folds, nor in the beaks.

1 A difficulty exists in the minds of some naturalists as to whom this name properly belongs, and it
is often given to Mr. Say. Mr. Lesueur gave the first specimen obtained to Mr. Say under this name; but
Mr. Say, believing it to be only a variety of crassus, so stated in Nicholson’s Ency., Am.ed. Tt still,
however, kept the name of plicatus, Lesueur, without any description, until Mr. Barnes, in Am.-Jl. of
Science, 1823, p. 120, described it as Lesueur’s. Therefore, if not Lesueur’s, it is Mr. Barnes’s species.
* It is extremely difficult to make out the species described by Dr. Hildreth in the American Journal
of Science. It appears, from a note by the editor, that he did not insert all the figures sent by Dr. H.,
but left out those which Mr. Barnes had already, as he thought, figured in the Jowrnal. Unfortunately,
in this omission Mr. Barnes’s figures are not referred to, and we are, therefore, in doubt whether Dr. H.
recognized, justly or not, Mr. Barnes’s species.
* The male of foliatus is certainly a triangular shell; the female differs in form very much, having a
deep inflection on the posterior basal margin. It may be doubted if this should be considered a plicate
shell. I think that the folds of the growth, particularly in the male shells, require it to be placed here.
* Sumatrensis being preoccupied by Dr. Dunker, I change the name to dimotus.
* Mr. Sowerby substituted this name for Uniopsis radiatus and mytiloides, Hanley, both being pre-
occupied.

2 Mr. Say, in his “Synonymy,” claims precedence in this species, although my } Memoir bears date
May, 1830, while his is December, 1831. (See Transylvania Journal, vol. v-) The reader will not, after
this, be surprised to be told that Mr. Say does not allow me, in his very incorrect “Synonymy,” to be the
discoyerer of a single new species of Unio from our western waters!! I may be allowed also to state, that
I do not understand why he gives the same name to two of his different numbers: thus, he calls No. 17,
U. interruptus, Rafin.; and No. 47, U. interruptus, Say. The species are evidently distinct.
*Lhave no doubt.of D. ellipticum being the same with my Unio multistriatus, and it is a true Unio.
Mr. Barnes gave the same specific name to an American Unio, but it had been prev iously described by
Lamarck as ligamentinus.

1Jn Jardines’s Mag. Zool. and Botany, vol. i. p. 285, Mr. Gray claims precedence for his name Dou-
glasize. He published it in Griffith’s Cuvier, bearing the date of 1834. My description, published in the
Trans. Am. Phil. Soc., vol. 5, dates March 16, 1832. (Note 1867. Messrs. Baird and Adams, in Zool.
Proc., May 9, 1867, are entirely incorrect in making Murchisonianus (1832) a synonym to Douglasiz
(1834), saying that ‘“‘Mr. Lea some years after described and figured a species from China,” &. Quite
the contrary; I described it, some years before, in the Trans. Am. Phil. Soc., vol. 5. In the same paper,
Messrs. Baird and Adams say that “after a careful examination of the description and figure of U.
Shanghaiensis (Lea), they are satisfied that it is the same, and that the name of Douglasiz must there-
fore stand.” That “the three species are identical.’ This is another error. Shanghaiensis is really
the same as Osbeckiz, Phili., with which I have some years since placed it in my MS. for this edition of
Synopsis.)
2 The specimen given to me by Dr. Dunker is so much like a young Murchisonianus, Lea, that I think
it will prove to be the same species.
° It is a matter of some doubt if this be more than a beautiful variety of asperrimus (nobis). Future
observation must determine. Ferussac and some other zoologists believe it to be distinct. Dr. Ward
says they “are certainly distinct.”

1 Mr. Say supposed this to be the rugosus, Barnes. Two specimens referred to by Mr. B. as rugosus
were under my inspection, and proved to be—the one a flat metanevra, Rafin., the other a plicatus,
Lesueur. Mr. B., in his reclamation, recognizes his rugosus as U. Peruviana, Lam., which shell is
undoubtedly the plicatus, Lesueur and Say.
* This variety of asperrimus I have had in my cabinet for about twenty-five years, and always
regarded it as too similar in its characters to raise it to a distinct species.
* This shell has been considered the female of asperrimus (nobis), but I have no doubt of its being
distinct. Some of our best western naturalists think it to be the true rugosus of Barnes.
* This may be found to be the male of Phillipsii Con., when the soft parts shall be examined.
* Prof. Kirtland thinks this may prove only a variety of pustulosus (nobis), but I am not of that
opinion.

* Never having seen the specimen described by Mr. Say as cicatricosus, I am unable to decide if it be
the same with varicosus (nobis). Two things mentioned by Mr. Say induce me to doubt it. He calls his
“‘a common species,” and says it is “distinguishable by the single series of transverse elevations on the
middle.” These remarks do not apply to varicosus, but they do to AHsopus, Green. I have always
deemed it a rare shell.
* Kuster figures (3) a male perplerus (nobis) as gibbosus, Raf. If his fig. 4 be taken from Mr. Con-
rad’s Monog., pl. 27, fig. 2, it is a sulcatus, Lea.
* Dr. Cantor, in the Annals of Nat. Hist., vol. 9, p. 489, gives the habitat of this species in Chusan
and in Canton River. He also describes a Unio, under the name of divergens, being “tuberculato-
plicata;” also, an Anodonta (gibbum), both from Chusan. Mr. Benson, in Journal Asiatic Soc., 1855,
says that divergens is distantly related to undulatus, Bar.

* Dr. Dunker, at Cassel, gave me a shell under the name of Castalia sulcata Krauss, from Surinam.
But it is not a Prisodon (Castalia); for, although it has the outline and general appearance, the teeth are
not striate, but granulate. It therefore belongs to the triangular Uniones, and the name of Unio sulcata
being preoccupied it must be changed, which I do to that of the able discoverer, Prof. Krauss — Unio
Kraussii. This species has remarkable transverse furrows like some of the species of Cyrena.

1 Say and Conrad both commit the error of giving precedence to nerus. My description of arce-
formis is in my memoir, read before the American Philosophical Society, May 20, 1831, while Mr. Say’s
was first described in the Transylvania Journal, of December, 1831. Subsequently, he republished itn
his American Conchology, No. 6, where he places erroneously the date of 1832 to my memoir.
* Mr. Barnes’s description of triangularis was made from a female shell, and mine of formosus from
the male. There being an obvious distinction of the sexes in every specimen, my error was a very
natural one, as we were not at the time acquainted with the sexual differences in the Naiades.
* Mr. Say thinks that Mr. Barnes’s wndulatus, Var. a, is the same with elegans. I think differently,
and would fortify my opinion in the fact that Mr. B. does not mention the zigzag rays which are strikingly
singular in the elegans, and could not have failed to elicit his remarks had it been under his eyes.
*T have expressed my doubts, Transactions of the American Philosophical Society, vol. iv. p. 84 (p.
94 in “ Observations on the Genus Unio,” &c.), if this be more than a fine variety of zigzag (nobis). Mr.
Say gives it as a synonym to nervosus, Raf., and Mr. Conrad as truncata, Raf. Prof. Kirtland thinks
this may be the female of zigzag. Iam disposed to think that zigzag should be considered only a variety.
If the soft parts prove to be the same, then certainly zigzag is a variety of donaciformis.
5 Mr. Conrad describes a Unio (Am. JI. Sc., vy. 21, Sec. Ser., p. 172) under the name of diversus,
from Shoal Creek, North Alabama, which, he says, is remarkably like heterodon in formand teeth.
°I received from Judge Tait, of Alabama, in 1830, several specimens of this species, but they were
not sufficiently perfect to induce me to publish them. Mr. Conrad does not mention the rays, a very
peculiar character of which is their being dotted somewhat like those of securis (nobis), but in a lighter
manner.

* Mr. Say makes “ventricosus, Bar., occidens (nobis), subovatus (nobis), (var), and capar, Green

species.
* Crassidens, Var. a, Lam., is trapezoides (nobis).

1 Perfect specimens of Unio Ravenelianus (nobis) look so much like maculatus, that I am disposed to

has precedence.
2 See note on Haysianus, Lea, p. 41.
* Say and Conrad both give trigonus (nobis) as a synonym to wndatus, Barnes. It is difficult for
me to understand why they should not at once, on comparison, be recognized as different species. The
trigonus is always more angular on the umbonial slope, and the undulations at the tips of the beaks differ.
This may be observed particularly in the young and perfect specimens. If a doubt could be admitted
as to the difference of the form of the shell, the color of the animal in ¢rigonus would at once settle the
question. It is peculiar, being red.
Some years since, when I described this species, I deposited a specimen in the Academy of Natural
Sciences of this city, with its proper name appended. Subsequently, I found the Academy had prefixed
the name of wndatus, Barnes, to the label. There is not a doubt as to its being specifically different.

1Tt is a matter of great doubt if this name ought to be admitted at all in this table. It was applied,
many years since, by the naturalists of this city, without reference to any particular specimen, but, as it
now appears nearly certain, incorrectly. Dr. Ward says the description and outline would “equally well
apply to six or eight different species.” The difliculty of recognizing Mr. Rafinesque’s species is well
illustrated in this one. Mr. Conrad, in New Fresh Water Shells U. S., considers triangularis, Raf., as
the type, and gives the following names of the same author as synonyms, Viz., lateralis, sintoxia,
pachostea, mytiloides, and rubra; thus charging him with making six species of one. But, what is still
more extraordinary, this single species (agreeably to Mr. Conrad’s synonyms) is not only divided by
Mr. R. into different subgenera, but into different genera, and even into TWO DIFFERENT SUB-FAMILIES! |
See New Fresh Water Shells of the United States, p. 72, and Mr. Rafinesque’s Monographie. In Mr. Say’s
Synonymy, triangularis, Raf., is considered to be the same as ellipsis (nobis)! Deshayes described a
different shell under the name of mytiloides. (Ency. Meth., p. 249, Fig. 4.) I doubt from this figure if it
be not a complanatus. We certainly have in our rivers, occasionally, specimens of this protean species
yery closely resembling this figure. M. Deshayes’s figure has some resemblance to an imperfect
Batavus. The habitat is not known. The confusion is increased by Mr. Conrad’s subsequent attempt
at correction. In Monography, 1836, he makes mytiloides a type, and puts rubra, Raf., pyramidatus, Lea,
and caridiacea, Guérin, as synonyms. Subsequently, in Synopsis of 1853, mytiloides and triangularis
are both dismissed as types, and the former made synonym to clava, Lam., while the latter is made
synonym to triqueter, Raf.!!
? Mr. Tristam, in Proc. Zool. Soc. 1865, p. 543, says he thinks that terminalis and Jordanicus, Bourg.
are the same, and that dignatus (nobis) seems to him to be identical with terminalis, but I doubt it.

*T doubt if the figure of Reeve (199) be made from a true anaticulus.
* This species has been supposed by some naturalists to be the same with perplerus (nobis). Mr.
Clark, of Cincinnati, informs me that the animal differs in color, being lighter. It is known there
vulgarly as the ‘White Mouth.” They are certainly distinct species.
* For some years, I was satisfied that Mr. Say’s ridibundus was only a variety of sulcatus (nobis).
There cannot now, however, be a doubt that it is the female of that species; and it may be remarked
that this serrated shell is usually found smaller than the other; a circumstance common with the females
of some other species. Mr. 8. describes and figures ridibundus in No. 1 of American Conchology, but
does not insert it in his Synonymy, in No. 6.
“Mr. Conrad described and figured a male and female shell from the Wabash under this name.
There is no doubt in my mind of their being the same with sulcatus, Lea (male), and ridibundus, Say
(female). Mr. C. thinks this species has some analogy to lenior, Lea, but it has not the same outline,
and differs in other characters. He thinks the males have been “confounded with that of torulosus, Raf.;”
but what is ¢orulosus, Raf.? Mr. C. considers it, in his Synonymy, the same with perplerus, Lea. Mr.
Say, however, discards torulosus, Raf., and considers perplexus, Lea, as a synonym to gibbosus, Raf.
Mr. C.’s figure of metastriatus is much more like lenior, Lea.

1T am very much disposed to think that Haysianus will prove to be the female of Sowerbianus (nobis).
They differ much in size, but in other characters are much alike, except in the female enlargement. The
latter is the larger, and has neyer, so far as I know, been found with charged branchial uteri. The former
usually has them charged, I am informed.
2 Mr. Say, in his American Conchology, refigures this, and recognizes my name. Subsequently, in
his Synonymy, he makes it a synonym of triangularis, Raf. Mr. Conrad says it is olivarius, Raf.
‘This and the preceding shell are so nearly allied, that it is a matter of doubt with me if it would
not be preferable to unite them. Dr. Ward thinks they are male and female. Subsequent examination
may throw sufficient light upon them to decide with certainty. Among Mr. Barnes’s varieties of ventri-
cosus, it is evident there are several distinct species. Prof. Kirtland, in Ohio Reports, says it is impos-
sible, with our present knowledge, to draw lines of specific distinction between the group consisting of
ovatus, ventricosus, occidens, subovatus, Ke.

1 Mr. Say considers capax as a variety of cardium, Raf., of ventricosus, Bar., of occidens, Lea, and
subovatus, Lea, while Mr. Conrad considers it as occidens, Lea. Capax is a perfectly distinct species,
and I had considered it so for some years before either Dr. Green or I described it. He preceded me a
short time, of which I was not aware, as it was published in an unusual periodical for such matter.

1 This may be a variety of Greenii, Lea.
2 Koch and Dunker described a fossil species (Menkei) in 1837: Beitrage zur Kenntniss, p.58. My
species was described in the Trans. Am. Phil. Soc. 1836, and must therefore have precedence.
‘Having recently had access to Retzius’s work (1788), I find that he described a European Unio
under the name of crassus, which species had been admitted into our systems under the name of crassis-
simus, Fer., I now restore it to its proper place under the name of crassus. Mr. Say described his crassus
as having “waves;” but his figure, inside view only, certainly is a species without “waves.”
Deshayes thinks that U. ligamentinus is analogous to U. multiradiatus, and probably a young indi-
vidual of it. This is not likely to be the case, however. The species are very different.
4 Mr. Barnes made eleyen varieties of crassus; most of which were, no doubt, distinct species; some
were plicate.
5 Mr. Conrad thinks the crassus of Say is fasciata of Rafinesque. An examination of his description
ought to satisfy any one that the crassus of Say could not have been under the eye of the author when
he made his description of fasciata.
® The specimen figured by Say, in Amer. Conch. No. 2, is a female shell. The male shell is not abrupt
at the posterior margin.

1 Dr. Philippi figures a Unio under the name of Australis, Lam. (Conchylien, Tab. 5, Fig. 5), from
New Holland, and says that U. ambiguus, Parreyss, is the young. I did not see Lamarck’s Woo
when in Paris; it was not in the Museum.
2 Mr. Say makes siliquotdeus the same with viridis, Raf. Ferussac, in his cabinet, makes it the same
with fasciata, Raf. Mr. Conrad makes it the same with vittata, Raf. Ferussac, in his ‘ Observations,”
states the inextricable difficulty resulting from the confusion caused by Mr. Rafinesque. See “ Observa-
tions,” p. 13, in Magazin de Zoologie.
5 Described from a female Juteolus, Lam.
4 Prof. Agassiz says, in MSS. cited by Mr. Stimpson, that this is not identical with the Ohio River
species usually called U. stliquoideus ; but I think they are the same.
5 T have never seen this species, but presume, from the figure in Griffith’s Cuvier, very poor as it
evidently is, that it is a distinct species. In the index, Mr. Gray inserts, in brackets (Unio Chinensis),
and says it has small compressed teeth. The figure looks something like a Monocondylwa, D’Orbigny.
° Spengler, in Skriy. Nat. Hist., v. 3, cites radiatus from Miiller, and as coming from the East Indies.
If from that part of the globe, it cannot belong to this species.

1 Mr. Blanford says it is a very peculiar variety of marginalis, and on the same page, says it is
nearer to corrugatus than to marginalis! Also that it probably is not Indian, but “has better claims to
distinction than most of Lea’s species.” It is very difficult for me to understand how any one, even
with a little experience, can confound this species with any other, it is so very different. I doubt if
Mr. B. has ever seen the species. It is not from the Ganges, but from Manilla, from whence many speci-
mens were brought by Com. Wilkes’ Expedition.
* The figure by Kiister has teeth, and cannot be an Anodonta. I think it must be the same as
Bengalensis.
‘ Mr. Blanford doubts if this be not the same with cwruleus, but they are different without doubt.

1 Very much the form of J. Batavus, Lam., and may prove to be the same. Voy. de la Mer Morte,

> Prof. Krauss informs me that he thinks this is only the young of his Caffer. But not having seen
each other’s specimens, there remains at least a doubt of it.
‘This and the previous species are very much like Batavus, and may prove only well-marked varie-
ties. The species in Algeria seems to be very much the same with those of the opposite side of the
Mediterranean in France and Spain. The land shells vary little in species, but the species are finer and
larger in Algeria.

1 Say and Conrad both, in their catalogues, give precedence to lapillus. Fabalis is in my Memoir
read before the Am. Philos. Soc., May 7, 1830, and inserted in the Transactions; capillus was first
inserted in the December number (1831) of the Transylvania Journal, and subsequently in the Amer.
Conch., No. 5 (August, 1832), under the name of lapillus. Mr. Say does not mention why he changed
the name on redescription. I should prefer the first, as a more descriptive name, were I to choose
between the two.
* 2 Probably a marked variety of germanus, Lea.
8 Mr. Say doubts if the glans be not the same with parvus. I do not see how there can be any
difficulty in distinguishing them. The glans is a much heavier shell, and the nacre of all the specimens
I have seen is more or less purple, while that of parvus is always, I believe, white. Among many hundred
specimens which have come under my notice, I have never seen one of any other color. The texture of
the nacre is also totally different, the latter being more pearly than any other of our Uniones. In the
epidermis and beaks they also differ essentially. Mr. Conrad describes and figures U. glans, Lea, in
Monog., p. 21; but the figure is evidently not glans. It is very like some of the varieties of U. obscurus,
Lea.
* U. Petterianus and U. carneus were sent to me by Dr. Vandembusch, of Bremen, as distinct species.
I believe the latter to be the old of the former, thrown out of its normal form by much erosion at the
beaks. They are from Montenegro, and may prove to be only a variety of Unio Batavus. See Kuster’s
edition of Martini, Pl. 26, Fig. 4.

which indicate this.

‘Ina subsequent paper, Jl. A. N. S., vol. ii. p. 295, Mr. Conrad says that, in referring the shell to
depressus, Lam., I have committed “an oversight.”
I do not admit this, but consider myself to be cor-
rect, having long had a specimen of U. depressus in my possession, and having seen it frequently in
various cabinets in Europe.

1 Turton’s figure seems to me to be an elongate variety of littoralis, analogous to that which I
described, in error, under the name of incurvus. But Forbes and Hanley say that littoralis does not
now exist in the waters of Great Britain, and is only found there in the Pliocene formation, in a fossil
state. If this be so, then Turton’s figure must be erroneously given.
2 T have some doubts whether this should be considered more than a variety of circulus. I am not,
however, sure that it is not distinct.
8 Although Mr. Say had published this shell in the Transylvania Journal, and in his Am. Conchology,
he omitted it altogether in his Synonymy. He inserted other species from the vicinity of New Orleans.
*T formerly placed this with the Anodontx, but D’Orbigny, who has seen the shell in its native waters,
having placed it among the Uniones, I follow him, never myself haying seen the shell. The figure of Dr.
Maton (Linn. Trans., vol. x.) is without teeth, and the text says expressly “cardo edentulus.” Notwith-
standing this, I am inclined to believe that D’Orbigny is right, for the form of the shell is such as I have
not seen in the Anodonte. Not knowing what induced M. D’Orbigny to change Dr. Maton’s name, I
have restored it.
(Since this note was published, M. D’Orbigny, in his Voy. Am. Mer., has come to a different conclu-
sion as regards Mytilus membranacea, Mat. He now thinks that my Anodonta lato-marginata is the same
- with membranacea, but I do not think that Maton’s figure can be referred to lato-marginata, even sup-
posing the figure of membranacea made by Maton to be from a young specimen. The outline is not the
same, membranacea being much more rotund, and the very great difference of solidity must have its
influence in our decision; lato-marginata being one of the thickest of the Anodontz. M. D’Orbigny, in
Mag. de Zool., 1835, gives Mya membranacea as a synonym to Unio Matoniana, and says the teeth are
thin; but he ought to have cited it as Mytilus, as Maton does not give Mya membranacea, but Mytilus
membranacea. M. D’Orbigny places it now among the Anodontx, and restores Maton’s specific name of
membranacea, and considers my lato-marginata as a synonym. It does not appear to me, from the
description and figure, that they can be the same.)

1The figure of this shell in the Lin. Soc. Trans., vol. x., although so much smaller a shell than
Paranensis (nobis), is so much like it that I should not be surprised if they should prove to be the same.
Lamarck considered this to be the same with his Hyria corrugata; but it is very different.
(Since the publication of this note, I have received, from M. Moricand, a suite of specimens of
Paranensis, which indicate, unquestionably, a distinct species. The beaks of rofundus, Wag., have not
the strong folds’on them, while the Paranensis has many elevated radiations from the beaks. The outline
too of the former is more orbicular.)
* M. Deshayes thinks this is incurvus, Say. I do not know where Mr. Say published a shell under
that name.
*In the recent edition of Cuvier Reg. An., by his pupils, there is a beautiful figure of U. retusus,
Lam., under the name of U. obtusa, Say. I am not aware that Mr. Say described a Unio under that name.
The refusus, Lam., is a common, well-known, and perfectly distinct species.
‘ Prof. Kirtland, in his Ohio Report, expresses his opinion of this being only a very flat variety of
subrotundus (nobis).
°> Mr. Conrad cites Mr. Say’s table of synonymy for politus, but I am not aware of Mr. 8. ever
having described it.

? The late Dr. R. E. Griffith had in his collection a shell marked catillus, he thought by Mr. Conrad
himself, but which I think was only a variety of obliquus, Lam.; certainly it is not the species figured by
Mr. Conrad. In a letter from Dr. Ward in 1836, he says, “U. catillus runs into coccineus, so that Mr.
Conrad would be puzzled to part the species in my collection. They are only varieties of the same species.”
* A single old valve (diam. .7, length 1.5, breadth .6 inches) was submitted to me, with a complete
young specimen 2.3 inches wide, by W. H. Benson, Esq., of London. The old valve is imperfect along
the dorsal margin, but still there may be observed imperfect cardinal and lateral teeth. In the young
specimen, the lateral teeth, while being very delicate and circular, are perfectly well defined, being double
in the left and single in the right valve. As Mr. Benson’s name (soleniformis, Jl. Asiatic Sec., vol. y., p.
750, 1836) has already been used for a Unio, I propose Bensonii for it in honor of the discoverer, who
has done so much for the Natural History of the East of Asia.
5 J have a deformed rectus so exactly like the figure given by Mr. Conrad that I cannot help thinking
they are the same.
* Mr. Conrad’s figure so nearly resembles the male specimens of U. rectus, from Green Bay, in my
cabinet, that I am persuaded the Sager? will not prove to be a distinct species. Drs. Kirtland and Ward,
and Judge Tappan, consider it a variety of gibbosus of Barnes. In Mr. Conrad’s Synopsis (1852) he
seems to have abandoned the name, as he has not inserted it there. ;
° M. Deshayes (2d edit. Lamarck) doubts if lanceolatus be not the young of anodontoides, “of Say.”
(Anodontoides was not described by Mr. Say, but by myself.) The first has been found only in the waters
east of the Alleghany Mountains, the last only in the western waters. There cannot be a doubt of their
being distinct species. In size they differ altogether.

? This is a curious and very interesting shell which I received from Vienna. Its habitat is Caryn
It may be only a remarkable variety of pictorum, Retz. Such is the opinion of some of the German
malacologists. a
* The tumidus, Retzius, is, I think, without doubt, the same as ovalis, Retzius, and other European
authors. But, Retzius having described tumidus before ovalis, the former name must take priority.
Prof. Mousson gave me in Zurich a specimen of this species, which, he says, came from Java.
* The well-known Unio pictorum of European authors, so widely distributed throughout that qua
of the globe, has been the fruitful source of trouble and perplexity to naturalists who have studied tl i
branch of Malacology. I have seen no reason to change my opinion, since the publication of the Is
edition of this Synopsis, as to the synonymy, which, unfortunately, is still going on to increase, to #
great embarrassment and injury of this branch of the science. I am well aware that some able wri
in Europe have endeavored to stem this tendency to multiply so dreadful a synonymy, such as U. pic
rum and An. cygnea present; and I find in the admirable work of Forbes and Hanley (now neat
finished), on the Malacology of Great Britain, ideas which are so entirely parallel with my own, that
cannot refrain from making the following extract. They say they “do not observe in Rossmaess
figures of continental forms of this polymorphal shell, any of which our islands do not exhibit a ne
analogous representation. If a certain platitude of language be demanded in a description of
preceding species, far more requisite is it that our diagnosis of the present one should be sufficiently
exclusive,” p. 144. (See note on An. cygnea.) 4

1 Chemnitz figures this shell, vol. vi. table 3, Figs. 23 and 24. From the description and outline, I
have little doubt of its being a young pictorum, more than usually undulated in the region of the beaks.
Its being rugose over the whole surface, as mentioned by him, is not evidence against its being such.
As the first growth subsequently forms the beak of the shell, it ought of course to be rugose, if that be
the character of the shell. The inside view is without teeth, but this is doubtless the fault of the drafts-
man or engraver, as the author speaks of the hinge being like the common mussel.
?T suspect this will prove to be the same as elongatulus, Pfeif., which may itself be only a var. of
pictorum. Swainson and Pfeiffer obtained them from Sicily.

Rey. Mr. Beadle, of Hartford, Conn. 2
* Mr. Agassiz says that the genus Unio, Retz., is represented in this country by U. nasutus, Lam.
Lamarck’s nasutus is gibbosus, Bar. Mr. Say preoccupied the name nasutus in 1816. Lamarck published
in 1819. In the synonymy of gibbosus, I have in all my editions of this work placed Lamarck’s nasutus
as a synonym to gibbosus, Bar.
’ This is probably the same as folliculatus, Lea, which latter name has precedence.
* Mr. Say, in his Synonymy, gives iris as a synonym to his subrostratus. If they were the same, I
would be entitled to precedence, as my description bears date March, 1829, while his is January, 1831.
His description, however, of subrostratus does not apply to my iris, and certainly this shell could not
have been under his eye when his description was made. He says that the swbrostratus “may be said to
be the analogue of the Unio nasutus (nobis) of the western waters.” As the U. nasutus inhabits the
western waters, a variety of that species may have been described by him for subrostratus.
° Novi-Eboraci and iris are in the outlines nearly identical, but in the soft parts there are differences
which I have pointed out in the Journal of the Academy Nat. Sciences, vol. y., N. 8., and Observations

the same as orientalis (nobis).

1 A fine suite of this species has been kindly sent to me recently by Prof. Haldeman, of Columbia,
Penn., taken from the Susquehanna River at that place. In most of them, I find the cardinal teeth of
the left valve to be trifid, and the lateral teeth of the same valve somewhat divided. In the right valve,
the cardinal tooth is nearly as long as the lateral tooth; in this taking somewhat of the character of
Triquetra subviridis, Klein. (Hyria of Lamarck).
2 T am disposed to think that this may prove to be the same with Javanus (nobis).
5 See note to Margaritana margaritifera.
‘1 think Mr. Children meant this species, but his figure (69) is evidently Unio alatus, Say, although
he cites it as European.
° This properly belongs to Margaritana. It is closely allied to WM. margaritifera. See my notes on

1 The genus Margaritana was proposed by Schumacher, in his Essai d’un Nouveau Systéme des
Habitations des Vers Testacés, published in 1817, for the Mya margaritifera, Lin. (Unio elongata, Lam.
and Alasmodonta arcuata, Bar.). Mr. Say, in 1818, proposed to establish this same division under the
generic name of Alasmodonta. The Danish zoologist, having priority of date, must have his name pre-
ferred. Mr. Gray, in his Genera, adopts Margaritana, but he cites Baphia, Gevers, in 1787. H.and A.
Adams, in Genera of Rec. Mol., give Baphia preference, and cite Meuchen, in Musewm Geversianum,
17387, as having priority, which I think is correct; and they make the following subgenera—Alasmodonta,
Say, Complanaria, Swain., Calceola, Swain.
* This species has a very wide geographical distribution. In the St. Lawrence and in the Northern
States, it is of ordinary size as it is in the Middle States; but in Ohio it is found large and thick, and
very perfectly developed. In South Carolina, Georgia, and Tennessee, it is smaller; and in Kansas, in
Verdigris River, it is very much like those in Pennsylvania.
8 Seyeral specimens of fine marginata have been sent to me from the west, marked Alas. truncata,
Say, being one of his unpublished names, but specimens given by him to various conchologists under
that name. I have never considered it distinct from the marginata of the eastern rivers, although it is
generally larger and of finer color in the exterior.

* It has been supposed that this might be the Alas. marginata, Say, but in a specimen received from
Prof. Troost, and returned to him, I found the beaks to differ essentially, the undulations being small
and numerous at the tip. It differs also in the teeth and other characters.
* This shell, in the teeth, except in the size of them, very closely resembles the Alas. edentula, Say—
An. areolatus, Swain. Although in both these shells there is a small cardinal tooth, in all their other
characters they so closely resemble the Anodonte, that it is a matter of doubt with me as to the propriety
of separating them from that genus. An examination of the animals, when satisfactorily dissected, may
show the necessity of placing them both, notwithstanding their possessing small cardinal teeth, with the
Anodontx. Swainson, in his Malacology, refers to radiata as his Uniopsis radiata; but this must be an
error. I think his shell is a thick var. of Marg. undulata, such as comes from Canada.
*In my Memoir in the Trans. Am. Phil. Soc., vol. iii. p. 420 (p. 34 of “Observations on the Genus
Unio”), I mention this shell as being closely allied to the genus Alasmodonta of Say. In this Synopsis, I
have deemed it better to transfer it to the subgenus Margaritana, as the lateral tooth is observable in
very few individuals. Deshayes says it is between Unio and Alasmodonta.
* Mr. Say, in his Synonymy, makes calceolus and marginata the same. I am surprised at this, as
their characters, in many respects, are very different, and I have never heard it even suggested before
that they could be confounded.

1 In the previous editions, this was placed among the Uniones with much hesitation. I now think it
groups better with the Margaritane. Its cardinal tooth is very much like JZ Bonelliz, and the callus of
the dorsal margin is sometimes, in both, so much thickened as to present an imperfect appearance of a
lateral tooth. Mr. Say’s description of ambigua answers well to Hildrethiana, but I am not sure it is
the same, as he has given no figure of it. He seems to have abandoned it, as he does not insert it in his
Synonymy. Mr. Conrad also avoids the insertion of it in his Synoptical Table.
2 Mr. Say, in his Synonymy, gives Mr. Rafinesque’s name of /afa precedence. Mr. Eaton says that
An. lata, Raf., is Symphynota tenuissima, Lea.
* Klein describes this species under the name of crassissima, but with no generic term. This name
has been, by Ferussac and other zoologists, erroneously applied to the large Unio, common to the south
of Europe, which Retzius described as Unio crassus, and I have given it to Retzius. Klein’s crassissima
is the true Margaritana margaritifera (Mya margaritifera, Lin.), and his figure of it, Pl. x. Fig. 47, is a
copy of Lister’s, Tab. 149, Fig. 4.
* Judge Cooper states, under the authority of Dr. Cooper, that the Indians east of Cascade Moun-
tains eat this species.
*T adopt Schumacher’s generic name because he has priority; but I discard his specific name of
fluviatilis because he changed, without any reason, the long and well-established specific name of mar-
garitifera.
® Fide Menke.
*T have been, and am still, perplexed about this species of Bose. M. Ferussac considers it the same
with Unio obesus (nobis), and I so stated it in my second edition. Recently, I have had access to Bose’s
description and figure (Hist. Nat. des Coquilles), which agree better with Margaritana margaritifera
than any other species; and he refers to the figure of it in Ency. Meth.

1 D’Orbigny, the distinguished traveller in South America, formed the genus Monocondylea for a
croup of shells which he first observed, and which possess a single cardinal tooth and no lamellar one.
This tooth certainly differs from that of the Margaritana, Schum. (Alasmodonta, Say). I am indebted
to the great kindness of M. D’Orbigny for his species. The shell figured by Spix, Pl. 25, Figs. 1 and 2,
under the name of Aplodon inerme, but not described in the text, evidently belongs to D’Orbigny’s genus
Monocondylea. It is certainly a most interesting group, and it is to be regretted that we have no
description of the soft parts. There seem to be three natural sub-groups in Monocondylea. 1. Francis-
cana, Paraguayana, Parshappii, Corrientesensis, and Guayrayana have the large tooth in the left valve
anterior to the large one in the right valve. 2. Vondembuschiana has the reverse of this, as is also the case
with inoscularis, Gould. These two are from the East Indies, while the former are all South American.
3. The fossiculifera differs distinctly from both these forms. The dorsal line is not bent into a curve by
the teeth, but is indented in each valve, the fosset being fitted by a corresponding projection. on the
opposed valve. This I propose to call Fossula. When the soft parts of the different species shall be
examined, these proposed divisions may be sustained, and the group will consist of MJonocondylea,
D’Orbigny, Pseudodon, Gould, and Fossula, Lea.
2 Dr. Gould described this shell in the Proc. Bost. Soc. Nat. Hist., Dec. 6, 1843, and proposed a sub-
genus (Pseudodon) for it. The hinge margin is formed exactly like my Monocondylaea Vondembuschiana,
and I have therefore placed it in that genus.
’ T am disposed to think, judging from M. Bourguignat’s figures, that my rhomboidea and his
Euphraticus, Opperti, and Churchillianus are all the same. If so, he must have preference.
* M. Bourguignat, in Voy. Mer. Mort by Sauley, describes this shell as having no lateral teeth, and
the figure evidently shows it belongs to the genus Monocondylwa. It is from Jaffa.
° In a letter from the Abbé Stabile, Milan, Jan. 1861, he tells me that Anodonta Uniopsis, Lam., is
only a small thin variety of Alasmodonta Bonellii, Fer. If Uniopsis and Bonellii be the same, then the
former has the preference, and the latter is a synonym.

1 Mr. Swainson discards the name of dipsas, because it was used by Larentini (1768) for a genus of
reptiles, and he says he gladly adopts that of Symphynota, Lea (Malac., p. 288). I think it better, how-
ever, that the rule recently adopted among most zoologists not to repeat generic names, should be more
prospective than retrospective, if adopted at all. Well and long established names are not likely to lead
to error. But the name of Barbala, Humphreys, has no doubt the pre-eminent title, and should take
precedence over all other proposed names, viz., Barbata, Sow., Cristaria, Schum., Appius, Leach, Diani-
sotis, Raf., Dipsas, Leach (1815), Symphynota, Swain. not Lea, Dipsax, Voight, if we allow the names of
Humphreys.
* Perfect specimens show the whole linear tooth, and the folds on the posterior slope and on the
posterior wing, but old and imperfect specimens sometimes exhibit neither. The imperfect figure and
description by Leach (who made the genus in 1815) of this fine shell, led me to believe that it could not
be the same with that which I described under the name of Sym. bi-alata.
5 Fide Dr. Gray.
4 Dr. Dunker, in Cassel, showed me a valve in his collection from Siberia, somewhat fractured,
which is undoubtedly the Dipsas plicatus, Leach. It is the largest specimen belonging to this family
which I have seen: in breadth about 12 inches; length 7} inches. See note on An. gigantea.
° Mr. Rafinesque, in the continuation of his Monograph (p. 7), affirms decidedly that the Symphynota
bi-alata, Lea, is a peculiar genus, but he changes it to Dianisolis Chinensis! !
° The posterior termination of the tooth shows some disposition to duplication, and evidently inclines
to pass into the subgenus Unio.
7 The figure No. 275 is not discoideus, Lea, but probably taken from U. levissimus, Lea.

1 As Bruguiere first separated this group from Unio, and called it Anodontites, it ought to be at least
mentioned if his name be not adopted. Anodonta is now so universally used that it might be doubted
if it should be changed. Bruguiére published in Hncy. Math. in 1792. Poli, in his great work, sub-
sequently reunites Unio and Anodonta. H.and A. Adams give the following subgenera: Symphynota,
Lea, Lamproscarpha, Swain., Patularia, Swain.
2 Dr. Gray, in Griffith’s Cuvier, Pl. 24, Fig. 2, gives a figure, without description, of a shell, under
the name of Unio tenuis, which he thinks is my An. magnifica; but it appears to me to be my Dipsas
discoidea. It is figured with the linear tooth of Dipsas.
8 The figure given by Dr. Schrenck in Reisen und Forschungen im Amur-Lande is not my magnifica.
I therefore propose to call it Schrenkii.
4 With some hesitation, I have placed this and forfilis under the division plicate, as the folds or
crimples are so small as almost to require a lens. But to place them in the division of “smooth” shells
would be, I think, more objectionable.
5 In letter of April 7, 1855, Dr. Gould says he has changed glauca (being preoccupied) to puberula,
and that it belongs to Monocondylea, O’Orb.

1 T have, after a good deal of consideration and examination of my specimens, and the figures in
the numerous works describing the Unionide, satisfied myself that An. cygnea and An. anatina are not
specifically distinct. If the observation of M. Poiret, that the first is viviparous and the last oviparous,
be correct, then they should be certainly separated. I feel perfectly persuaded, however, that he must
be in error. Turton, in his recent work on the Land and Fresh Water Shells of Great Britain, says he
is “inclined to think that all our supposed species of this genus may be justly resolved into one.” M.
Gras (Description des Moll. Fluv. et Ter. de la France) says that anatinus is only the young of cygneus;
and Dr. Gray says, in his Manual of Fresh Water and Land Shells, that it is a most variable species, and
that “we must not only dissent to the division of this polymorphous bivalve into these numerous species,
into which it has been separated by the continental writers, but even demur to the possibility of arrang-
ing the diversities of shape and coloring into strictly different varieties.” ‘Like Unio, this genus is
chiefly American, only one distinctly-marked species inhabiting Europe.” Such has been my opinion for
more than twenty years. (See note on Unio pictorum.)
2 Middendorff (Sibi. Reise) refers to his Pl. 21, Figs. 4. and 5; Pl. 22, Figs. 1 and 2; and PI. 26,
Figs. 1 and 2, for An. cygnea, but Figs. 1 and 2 on Pl. 22 are undoubtedly Dipsas plicatus, Leach.
° 6 of Maton and Racket (Lin. Soc. Trans., vol. iv.) is evidently, judging from the figure, Unio
litoralis.
* Gmelin states this shell to be from the fresh waters of Europe, and allied to Anatina. If this be
true, there cannot be a doubt of its being the same with cygnea. The fluviatilis of Solander and Dillwyn
is said to be from North America, and Say’s catfaracta is the same, no doubt.

2 This and grossa are certainly very different in aspect from the cygnea, Lam., being more pon-
derous and less produced behind. This difference may, however, be effected by locality. Should it
prove constant, ponderosa ought to be considered a distinct species, and such may prove to be the fact,
but I doubt it much.
’ I presume that Bosc meant the same variety as Myf. fluviatilis, Gmel. But he refers to Lister’s
Pl. 157, which is probably Unio cariosus, Say. Bosc refers to Europe for the habitat of his species, and
certainly there is no species in Europe like Lister’s figure.

of fragilis, Lam., attributable to different habitats and local effects.

1M. Rang informed me that this species has the singular power of maintaining its vitality in the
desiccated marshes of Africa, through six months of the burning sun of that region; and that he had a
specimen sent to him in Paris, which was killed nearly thirteen months after it had been taken from its
native bed, having occasionally been dipped in water for an hour or two only. He also mentions that
the Iridina rubens is found with the Chaiziana in the Senegal, and possesses the same peculiarities of
remaining in a state of torpidity during the season of great heat. A specimen, under the name of Chaiz-
dana, sent to Dr. Jay from Europe, and given to me by him, is, I think, a young Iridina rubens. Dr.
Vandembusch, of Bremen, sent me, more recently, a thicker and more inflated specimen under the name
Epigenia decorata, of Parreyss and other Vienna naturalists. This appears to me to be the female of the
same species. I think it possible that An. Chaiziana, An. Tawaii, and E. decorata may all prove to be
identical, varying by geographical position, sexual difference, or age. I have had very strong doubts
whether this be not a young Jridina rubens, but the two specimens I have seem to be mature, and Rang
describes and figures his Chaiziana without siphons. The lesser of the two anterior cicatrices is smaller
in my two specimens, and more elongate, than in rubens.
2 T doubt very much if Dr. Hildreth had Mr. Say’s undulata under his eye when he made his descrip-
tion. The undulata of Say does not exist west of the Alleghany Mountains, and Dr. Hildreth probably
had some other species, which, not being figured and the description being imperfect, I cannot make out.
The species is said to be found in Oneida Lake and Lake Champlain.
? Von Martens (Malac. Blatt. 1867) considers the following to be synonyms: An. Boroughiana, Lea;
U. Bengalensis, Lea; U. verecundus, Gould; An. subcrassa, Lea; An. tenuis, Lea; An. crepera, Lea;
An. gracilis, Lea. He is certainly mistaken in most of these at least.

1 Prof. Kirtland informed me that he received this shell from Wallingford, Conn., taken from some
of the branches of the Quinipiak River, but I think this must be an error. When I described it, I
mentioned having purchased it of Mr. Warren, a dealer in Boston, who could give me no idea whence it
came. I never supposed it to be an American species, and my conclusion is justified, I think, by having
received the same species from Dr. Vondembusch, of Bremen, he having procured it from Java.
2 Férussac considered trigona the same as crassa, Swainson. The two figures, however, appear to
me to be too different to be considered the same.
* The specimen sent tome by M. D’Orbigny under the name of si7ionos does not correspond with
his figure in Voy. Am. Mer., Pl. 74, Figs. 4-6, and Pl. 80, Figs. 1 and 3, which I think are drawn from a
lato-marginata, Lea; but it is, I think, the same as ¢rigona, Spix.
* The Patagonica and lato-marginata, when they are better observed, may prove to be the same.
®° Spix’s figure so closely resembles the lato-marginata, that I scarcely feel a doubt as to their being
the same. He does not, however, notice the broad margin which is so characteristic of this species.

1 So far as I have been enabled to examine specimens of this and trapezialis, I am disposed to
think they are not distinct species.
2 The figure, Pl. 90, given in the edition of Cuvier by his pupils, is said to be reduced to one-half.
It seems to me to bea good representation of An. lato-marginata (nobis), and not like Lamarck’s exotica.
8 T have not seen this shell. It seems to be nearly allied to Blainvilliana (nobis), judging from the
figure in Griffith’s Cuvier, Pl. 19, Fig. 3. It is from Paraguay.
‘ This very curious and interesting species was described from a single imperfect valve, brought by
Mr. Nuttall from Oregon. Some years afterwards, Lady Catherine Douglas recognized it among the
shells sent by Sir George Simpson, from Vancouver, and to her I owe the possession of a fine and perfect
specimen. In the collection of the Exploring Expedition, I recognized many fine specimens which
Captain Wilkes brought from Columbia River. Some of them my friend Dr. Gould has since character-
ized as a distinct species, but in this I should not agree with him. Mr. Hinds found this species abund-
ant in the Rio Sacramento, California, where he says it was used as food by the Indians.
® I do not see any reason for proposing a new genus for this shell. If the irregular dorsal margin
required its being removed from Anodonta, then it should be placed in D’Orbigny’s genus Monocondylea.
6 Mr. Reeve quotes Say for fenebrosa, but Mr. Say described no Anodonta by that name to my know-
ledge. It is evidently my tenebricosa from South America.
7 The figure of Cailliaud, Voy. @ Meroé, vol. ii., Pl. 61, is exactly like a specimen sent to me many
years since under the name of arcuata, Fer., from the Nile.

6 A specimen of this shell from the River Onon, Northern Siberia, was presented to the Boston Soe.
Nat. Hist. by Dr. Gould. It is stated to be “11 inches long and 6} high.” (Proceedings, March, 1849.)
I presume this is a distinct species, but, without a description or view, I am unable to determine. The
name, however (gigantea), is preoccupied, and I propose to substitute Ononensis, as the author’s name
(Middendor fii, Siesm.) is also preoccupied. Is it not possible that this may be an old Dipsas plicatus,
Leach, with the teeth obliterated?

2 In my description of Blainvilliana (Observations on the Genus Unio, vol. i. p. 189), I observed that
I was induced to believe that the animal of this shell would be found to differ from that of the genus
Anodonta. M. D’Orbigny, in his Synopsis of the Fresh Water Shells of South America, has in fact so
found it. The animal has two tubes. Nevertheless, although I then proposed, if such should be the
case, that it should be placed in a new genus, under the name of Columba, I continued it in the subgenus
Anodonta, as, with the artificial system, which is founded on the hinge, I thought it could not with
propriety be elsewhere classed. I then mentioned that when the family shall be arranged in a system
founded on the animal structure only, it evidently must be changed, and I doubted then if it should be
placed in the genus Jridina, for, although it is likely that all the species of that genus have two tubes,
they do not seem to possess the inflected palleal cicatrix, which I noted in the description of Blain-
villiana. There being now at least two distinct species known, I have thought it best to classify the
genus Columba as proposed March 15th, 1833 (Obs. vol. i. p. 190).
° In a letter from Dr. Gray, Noy. 1834, he states that his Parishii and my Blainvilliana are the
same. His paper is dated July 8th, 1834; mine, March 15th, 1833.
4M. D’Orbigny, at p. 43, Synopsis Ter. and Fluv. Mollusque, makes An. trapezialis, Lam., a synonym
to his Iridina trapezialis; but I think that Lamarck’s An. trapezialis is a different shell. I cannot but
think that D’Orbigny’s I. trapezialis is my An. Blainvilliana.
5M. D’Orbigny thinks that this is my Blainvilliana, but, having his specimens and mine of both
these species, I am induced still to believe that I am correct. The two specimens resemble each other,
but are certainly distinct. The inflected palleal cicatrix exists in both, but the esu/a is more curved, and
the dorsal margin is more sinuous, the nacre being bluish white, while the five or six specimens of Blain-
villiana which I have seen are all salmon color.

2 When Lamarck established his genus Jridina, he had seen but a single species, and of that only
one individual, which is figured in the Hneyclop. Méthodique, Pl. 204. Other species have been since
referred to his genus, which do not seem to me to fulfil the conditions of his generic diagnosis. The
phrase “cardo per longitudinem tuberculosus, subcrenatus,” is by no means descriptive of the hinge
belonging to the species just alluded to, which has the hinge smooth, or very slightly tuberculate. The
figure in the Encyclopédie, and that of Blainville (Pl. 66, Fig. 8), represent the same individual, and
exhibit a character of hinge resembling in some measure that of an Arca. A second species, apparently
agreeing with Lamarck’s generic description, has been observed and described by Swainson, under the
name of Iridina ovata (Phil. Mag., vol. \xi.); and it has also been described by Mr. Children under the
name of I. exotica (Brande’s Journ., vol. xv.). The specimen described in Brande’s Journal is now in
the British Museum, and that accurate naturalist, Dr. John Edward Gray, who is one of the officers of
that noble institution, informs me that he thinks it is identical with the shell upon which Mr. Conrad has
lately proposed to form a new genus, Pleiodon. Under these circumstances, it seems to me necessary to”
separate those shells having a crenulated hinge (which are true Iridinex), from those having the hinge
smooth, or very slightly tuberculated. J therefore arrange the Iridina rubens, Nilotica, &c., in a new
subgenus, for which I propose the name of Spatha. In an intemperate note by Mr. Conrad, on the cover
of No. 11 of his Monography, he says that I refer P. Macmurtriei to Iridina ovata, because Dr. Gray
thinks them identical; and further says this “must be a wilful error” on my part! But this irritable
remark cannot alter the fact. Jt is identical. Mr. Swainson (Malacology, p. 286) says “the name of
Pleiodon cannot be substituted for that of Iridina, as applied to the typical species.”
Ferussac says that Humphrey, in his Catalogue (MSS.?), made a genus (Scapha) for an Iridina, and
that the “mutel, D’Adanson,” is certainly the same (Mém. de 1’ Hist. Nat. de Paris, v. i. p. 362).
’ This has so much the characteristic of ovata that I should not be surprised if it proved eventually
to be a well-marked variety of that species.
* Mr. Sowerby very kindly presented me with a specimen under this name. It looks to me like a
young J. ovata, and I have little doubt but that it will prove to be such.
° M. Deshayes gives the Nilotica as a synonym to this species, but I think it is distinct.

1 This genus, established by M. D’Orbigny, has the dorsal margin smooth like Anodonta; but that
and the basal margin are nearly parallel, and the posterior margin is truncate. The soft parts of the
animal figured by D’Orbigny represent it to be very different in the form and size of the foot, which it
extends enormously. He mentions that the two anterior cicatrices are widely separated. A more
important character appears to be in the fact that the smaller cicatrix is placed before the larger one.
In Unio and Anodonta, it is placed below it, and in Hyria, Lam., it is placed above, that is, in a
line with the beak. Its habits are different from the Unionide generally, as it buries itself over a foot
in the sand, “perforat, sicut pholade.” In this characteristic it is analogous to Margaritana dehiscens
(p. 69), Unio dehiscens, Say, which my brother, T. G. Lea, informed me he found only at a depth of 12
inches below the surface of the sand on the bars of the River Ohio, their position being ascertained by
a small hole at the surface kept open by the animal. The foot is capable of great extension. See
description of soft parts, Obs. Vol. X. p. 76.
2 This has very much the appearance of a deformed shell, as figured by Reeve, No. 3.
® Mr. Conrad proposes to create a new genus (Solenaia) for this species (Am. J/. Conch., vol. iv. p.
249), it having, he says, “a lateral tooth in each valve,” which it has not, there being then only a “slight
long rising,” as originally described by me. I presume Mr. Conrad had never seen the shell.
* Mr. Higgins has described and figured this species (Zool. Pro., 1868, p. 179), which he received from
Mr. E. Bartlett, who discovered it in streams near Chyaretas, Upper Amazon. It is closely allied in
all its characters to emarginatus (nobis), and I have admitted it above as a distinct species. If the
habitats be correct, and I have no reason to doubt them, we have in Mr. Wheatley’s collection and
mine, together with Mr. Higgins’ authority, the two distant habitats well established. alcatws seems to
be a smaller species, more emarginate, corrugate on the posterior slope, and the angles of umbonial and
anterior slopes are more acute.
§ Having the two shells An. siliquosa and An. pygmexa, Spix., before me, I cannot doubt of their
being distinct; and I believe they both belong to D’Orbigny’s genus Mycetopus.
6 Voyage dans l’ Amérique Méridionale, tom. v. partie iii. Pl. 12, Fig. 1-3. The figure of ventricosus
approaches so much that of siliquosus, that I would not be surprised if it should prove to be simply a variety.

In Mr. Rafinesque’s Monograph, and in his subsequent Papers, are inserted
descriptions under the following names. Not being able to identify them, I have
deemed it better simply to give a catalogue of them. Those which I suppose I have
identified will be found in the foregoing table. In this list, I have not divided the
Unionide into his numerous genera. The want of adequate figures, and an absence
of sufficiently accurate description, together with Mr. Rafinesque’s well-known
proclivity to make species out of imaginary forms and specimens, induced me, after
repeated and vain attempts to recognize his species, to follow the example of Mr. Say,
Mr. Barnes, and all the other American malacologists up to the time of commencing
my memoirs on this subject, to avoid any further attempt to elucidate a mass of
confusion which was considered beyond the pale of science. The views of the late
Dr. Binney, in his Terrestrial Molluscs of the United States, Prof. A. Gray, in Amer.
Journal of Science, and Major Le Conte, in the Proc. Acad. Nat. Sciences, in relation
to the claims of this writer, are so conclusive that it is only necessary for any unpre-
judiced mind to examine the facts and be perfectly satisfied that Mr. R. has, so far
from advancing science by his writings in this branch, been the cause of inextricable
confusion, from the embarrassment of which we can only be relieved by altogether
avoiding any further attempt to make out his imaginary species. M. Ferussac, who
made vain attempts to understand his division and species, says that the shells he
sends away augment the difficulties in knowing his own species, and that he had
received the same shells under different names, and others with the names evidently
different from those given in his monography; that the difficulty, therefore, is inex-
tricable in the determination of his species, &e.

Srnce the printing of these Tables was commenced, about a year since, the following matter came
under my notice, and I have deemed it important enough to put it in this form.
In the Journal of the North-China Branch of the Royal Asiatic Society for December, 1865, which
came too late into my hands for notice in its proper place, I find a very interesting article entitled
Notes on the “ Geology of the Great Plain,” by Dr. Lainprey, Surgeon H. M.’s 67th Reg’t. In the care-
ful examination of the district of Shanghai he gives the product of an artesian well, 252 feet deep.
Between 45 and 60 from the surface “fragments of shells’ were found, and plants and bark of a tree at
180 feet. In an earth pit, “land shells and stems of plants” were also found. ‘Two feet from the surface
there were fossil shells of Paludina,” &e. p.11. Further on, p. 14, he says that “‘remains of shells
belonging to Paludina, Planorbis, Unio, Anodonta, and Cyrena are scattered over the surface of the
soil both in Kiang-see and Pe-chi-li, and buried in it at various depths. They are also found ‘still
in a living state.” Among the bivalves found he says “I have met with a form (figs. 20 and 21) which
appears to be a marine species; it is found in a fossil state in the low swampy ground at the south
side of Tien-tsin city,” &c. This very remarkable shell is unquestionably Triquetra contorta, Lea: see
Obs. on Unio, vol. vi. p. 39, pl. 33, f. 33, specimens of which I obtained and described in 1857 in the Jour-
nal of the Academy of Natural Science as coming from the fresh waters of Northern China, some of my
specimens coming from Shanghai. Dr. Lamprey figures two other species of Unionide without specific
names. ‘Anodonta, fig. 14,” is Dipsas discoideus, Lea. Obs., vol. i. p. 187. ‘Unio, fig. 15,” is Unio
Wrightii, Lea. Obs., vol. xii. p. 43. He mentions other specimens, one of which he says is an Anodonta
of “10 by 6} inches.” This is evidently Dipsas plicatus, Leach. A “Unio 8 inches by 53” is unknown
among Chinese collections, and is probably a more perfect specimen of D. plicatus.
A very valuable paper, ‘ Ueber sudbrasilische Land- und Susswasser Mollusken,” by Dr. Ed. von
Martens, in Malakoz. Blitt. 1858, was not in my possession in time to place his name after the species cited
which he there notices. There are twenty-nine species of Unionide which had been described by Lamarck,
D’Orbigny, Spix, Kuster, Hupé, and myself, many of which he considers to be synonyms.
Another valuable memoir came too late to be inserted in the systematic tables: ‘ Beitriige zur Ent-
wicklungsgeschichte der Najaden,” by Dr. F. A. Forel, Morges, Switzerland. This is a most able exposi-
tion of the development of the Unionide, giving the histology of the subject, and executed with a
minuteness and perfection heretofore unreached as to embryonic development and anatomical exactness.
There are three excellent plates with accurate figures of the progress of Maturation of the Ovarian Ege,
Segmentation of the Yolk, Byssus organs, &e.

Malzine, in Essai sur la Fauna Mal. de Belgique, 1869, gives the following as new species, which I con-

Gentiluomo, in Bull. Mala. Ital., Pisa, vol. i.:
Unio Lawleyianus.
Morch, in Am. Jl. Conch., vol. v. p. 38, informs us that Unio Grenlandicus, Schrot., is the same as testu-
dinarius, Speng. (marginalis, Lam.) from Tranquebar.
Villa. <A letter of March 10, 1870, from Sig. Villa, Milan, asks my decision on a Unio Danelli described
by him, from Melbourne, Australia, but I have not had the advantage of seeing the shell, nor of
receiving the description which he sent to me.
