A LIST OF THE GENERIC AND FAMILY NAMES OF
RODENTS.

BY T. S. PALMER.

Generic names of mammals have undergone many changes in
recent years, and in no group is this more apparent than in the
Rodentia. Not only have new names been proposed for a host
of new forms, but many well-known genera now appear under
names long forgotten, but revived in obedience to the law of
priority. Linnseus, in 1758, recognized only six genera of ro-
dents (including Rhinoceros!) ; Agassiz, in 1842-'46, recorded about
220 generic names in this order, and Marschall, in 1873, added
65 more, making a total of somewhat less than 300. The present
list contains more than 600 (a large pro})ortion of which are, of
course, synonyms), comprising perhaps 15 percent of the entire
number of generic and subgeneric names ever proposed for
mammals.

Recent changes in the nomenclature of the Rodentia are well
exemplified in two important papers which have appeared dur-
ing the past few months— one, by Mr. Oldfield Thomas, entitled
'On the Genera of Rodents';^ the other, by Dr. E. L. Troues-
sart, comprising part of the second edition of his ' Catalogus
Mammalium.' The former paper gives merel}^ a list of the groups
of living rodents which the author considers worthy of generic
rank, together with references to the original description of each
genus. Trouessart's Catalogue, more ambitious in its scope, is

intended to include all the species, living and extinct, now recog-
nized. Even with these aids the student will often find difficulty
in looking up synonymy or determining the earliest name of a
genus, for Thomas gives only about one-third of tlie names, while
Trouessart does not pretend to include all the generic synonyms
and frequently omits references.

The present paper differs from either of those just mentioned.
It is neither an index nor a catalogue of recognized genera, but
merely an attempt to bring together all the names, generic and
subgeneric, ever proposed. It is not complete in itself, inasmuch
as it gives neither references to descriptions nor localities ; but
the authority, date of publication, and type or included species
under each name will throw some light on these points. In ar-
ranging this list everything has been subordinated to convenience
of reference. Genera and subgenera have been treated alike and
distributed under families, while the alphabetical arrangement has
been followed both in the sequence of higher groups and in the
names under e^ch family. Some difficulty has been experienced
in properly grouping the genera, and about a dozen names have
not been referred to any family for lack of sufficient information
regarding their status. Thomas' classification of recent genera
has been followed, except in the case of Lophiomyidas, which is
given full family rank, instead of being placed as a subfamily
under Muridse. To these 22 groups have been added 5 additional
families of extinct rodents recognized by Zittel,' making a total
of 27 families. More than 200 names occur under Muridse, and
for simplicity they have been placed under subfamilies, but this
is the only instance in which the alphabetical arrangement of
the family has not been followed.'''

The date is alwa3^s the year of actual publication, often very
diff'erent from the date of apparent publication. For example,
the description of Schizodon was published in the Proceedings of
the Zoological Society of London for 1841, but it did not actually
appear until March, 1842. Arctomys was described in a part of
the fourth volume of Schreber's Saugthiere, issued in 1782, but
the name was first published on plates accompanying this work,
which are known to have been distributed in 1780. Schizodon

"^ I am indebted to Mr. Thomas for looking over the genera of Miiridx
and Octodontidse and for several suggestions as to the arrangement of the
list.

is therefore quoted as 1842 and Ardomys as 1780.^ Preoccupied
names have been marked, and cross-references made to those
proposed to replace them. A few names have become ahnost
unrecognizable by reason of the changes they have undergone
in the process of emendation. Among such may be mentioned
the correction of Aplodontia to Haploodus, Pithecheir to Fithe-
cochirus, and Coelogenus to Genyscoelus.^ The original spelling is
always given, but no attempt has been made to include all
variations, although the more important have been noted. If
the first letter of a word has been changed, both forms have
been inserted in the list, but other changes have been indicated
in foot-notes.

Each genus is followed by the type or species on which it was
based. When no type was designated and none has been indi-
cated by a subsequent reviser, all the species are mentioned in
the order given in the original description. No doubt some
errors will be detected here, for at first an attempt was made to
determine the types for as many genera as possible. This plan
was subsequently abandoned in favor of an enumeration of all
the species originally mentioned, but some cases of elimination
may have escaped correction.

More or fess lack of uniformity exists in the nomenclature of
certain families, as, for example, in the cases of the American
Porcupines and Chinchillas. Thomas, considering the New
World Porcupines worthy of separation, erected the family Ere-
thizontidse, and Trouessart, a few months later, recognized the
same group, bat renamed it Coendidas. No less than three family
designations for the Chinchillas are in common use — Chinchil-
lidWj Eriomyidse, and Lag ostomy idse. Such a condition of things
is obviously unnecessary, and can only lead to confusion. As

* While this paper was in press, my attention was called to Sherborn's
announcement of the discovery of Lacepede's well-known * Tableau
Methodique' (usually quoted 1801), in the Didot edition of Buffon's
Histoire Naturelle, Quad., vol. XIV, 1799 (Nat. Sci., XI, p. 432, Dec,
1897). Lacepede's genera Agouti, Arvicota, Coendou, Hamster, Pika, and
Talpoides therefore date from 1799, instead of 1801, but the necessary
corrections could only be inserted in the cases of Pika and Talpoides.

'^In explanation of this remarkable emendation the author says: " Le
u grec ne repondant pas a I'u latin, le nom de Cuvier \_Coelogenus'] n'est
pas acceptable, puisqu, il renferme une faute d'orthographie ; et, pour
faire un nom d'apparence reellement latine, il aurait au moins fallu
^crire Genyscodus et non Coelogenus.^' Liais, Climats du Bresil, 1872, p. 537,

244 Palmer — Generic and Family Names of Rodents.

an aid in selecting the proper name in such cases and to help in
determining questions of priority, it has seemed best to give
under eacti group all the family and subfamily names based
on genera belonging to it. Full references have also been in-
serted, inasmuch as authors seldom indicate the place where
such names were first published. Groups first described as full
families and afterwards reduced to subfamilies have merely a
reference to the original description, but those first introduced
as subfamilies and afterwards raised to family rank have refer-
ences to both places of publication. This part of the list has
been limited strictly to names ending iit ' idx ' or ' inse^'' the only
exception being old designations with the closely related termina-
tion ' ma.' Here, as elsewhere, the object has been merely to bring
together under each family all the available names, without at-
tempting to discriminate between synonyms and names which
have a claim to recognition.'

This list is supplementary to a complete alphabetical index of
the genera of mammals, containing full references to descriptions
and localities, which is now almost ready for the press. The data
relating to the Rodentia are here grouped under families and
published in condensed form for the purpose of inviting sug-
gestions and criticisms as to arrangement, type species, and
grouping of genera. The list is therefore merely an experiment.
Although the names have been brought together, much remains
to be done in working out the synonymy of types, but such work
properly belongs to the specialist and the reviser of groups.
When this has been done some examples of duplication of names
will probably be found even more striking than the case of the
lemmings, in which a single species {Mils torquatus Pallas) has
served as the basis for five or six nominal genera.

As a help in distinguishing the names, extinct genera are
printed in italics ; an asterisk (*) indicates that the original
description has not been seen; a dagger (f) that the name is
preoccupied, and a double dagger (J) prefixed to a family or
subfamily that the name is not available, either because the
genus on which it was based is preoccupied or because it is
antedated by some other valid name.

^ Forsyth Major has recently proposed Nesomywfe for certain Old "World
mice usually classed under Cricetinx ; but as he does not give the limits
of this group Thomas' classification is necessarily followed, although
Nesomyinx may be entitled to subfamily rank as much ?is the group under
which it is placed,
