EDITORIAL NOTE.

In 1904, the late D. G. Elliot published ' A Check-List of the Mam-
mals of the North American Continent, the West Indies, and the
Neighboring Seas.'1 Shortly before his death he prepared the man-
uscript for a supplement to this work, carrying the subject to about
the end of the year 1914. On examination, at the request of his
daughter, Miss Margaret H. Elliot, this manuscript was found to be
practically ready for the press, and was submitted by her to the
authorities of the American Museum of Natural History for publica-
tion at her expense, under the auspices of the Museum, provided it
proved acceptable. It is here presented as written, with only such
revision and verification of references as the circumstances of posthu-
mous publication naturally require.

The original edition of the Check-List gave fully the bibliographi-
cal references required in a modern check-list, together with the type
localities and geographic distribution of the forms included, and also
references to his previous works 2 where full descriptions of the forms
are given. The species and subspecies included in the Supplement
have for the most part been described since the publication of his
earlier works, on which the Check-List was based, and it was evidently
the author's intention to make this publication not only a supplement
to the Check-List, but a continuation of his preceding two manuals of
the subject, by giving descriptions of forms added as well as the usual
check-list matter. As known to his fellow-workers, it was his custom
to base his descriptions on the type specimens of the species and sub-
species involved, instead of compiling from the original descriptions.
For this reason the descriptive portion of this supplement is incom-
plete, in cases where the type specimens chance to be in foreign
museums or in the museums of the Pacific coast and Canada. De-
scriptions of some of the forms published in 1914 had also not been
completed, especially with reference to the measurements of the skulls.
The Editor regrets that it proved impracticable to have these blanks

filled, at least without causing much delay in the publication of the
work, thus leaving a few of the descriptions incomplete.

It is to be noted that the Supplement contains many changes in
generic nomenclature from that of the original Check-List, many
groups treated in the latter as subgencra being here given the rank of
genera, while the changes in generic names shown to be necessary
since the publication of the Check-List are duly recorded in the
present supplement.

Type locality. 45 miles south of Calmalli, Lower California, Mex-
ico.

Genl. Char. Horns shorter, rough; molar series heavier than in
A. americana; slight differences in color of pelage.

Color. Compared with A. americana. Like that species, but the
black border on terminal half of ears is broader, and the terminal third
of the outer side of ears is blackish, the tips being pure black; rufous
area on top of tail extends forward as a well-marked bar dividing the
white rump-patch. Size of the two forms about the same. Ex type
in United States National Museum.

Measurements. Skull: total length, 287; occipito-nasal length,

I cannot perceive any characters sufficient, in my opinion, to sepa-
rate this animal from typical americana. Those mentioned by Mr.
Nelson, both of color of coat and difference in skull, are individualistic
rather than specific, and on comparing the type skull with those of
typical americana, the molar series are not found to be any heavier.
I therefore regard peninsularis as the same as americana of which it
would be a synonym.

Museum from the Methow River, Washington, and that it is a valid
species.

In a paper published in the Proceedings of the Biological Society
of Washington, Vol. XXIII, 1910, p. 57, on "The Generic name of
the House Rats," Mr. G. S. Miller, Jr., shows that the term Epimys
(Epinomys} Trouessart should be applied to the House Rats, of which
by tautonymy, Rattus domesticus Fitzinger — Mus rattus Linn., is the
type; and that Mus musculus should typify the genus Mus Linnaeus.1

The introduced species occurring in North America would there-
fore stand as follows :

Dr. Mearns (/. c.} has, in his paper, called attention to the fact
that of the names of the above three species, the first two were pre-
occupied, viz. arcticus Mearns 1910 nee arcticus Saussure of Coues,
1877, and as this name is a synonym of Hesperomys maniculatus Wag-
ler, arcticus cannot be employed in the nomenclature of this genus,
and may not be used for the race from Fort Simpson, Mackenzie,
Canada, and for which he proposed the name borealis. The synonymy
of these three forms would therefore stand as given above.

Type locality. Hursman Lake, Scriven County, Georgia.

The type of Wagner's species is in the Universitat Institute und
Sammlungen in Zurich, Switzerland, where it was examined by Mr.
Osgood who says of it (/. c.) "its identity as a member of the group of
small mice containing the forms well-known under the names sub-
griseus and niveiventris is obvious. It is said to have come from
Georgia, and its color, which is not greatly changed by exposure, agrees
well with recently collected specimens from that region."

Wagner's name will therefore take precedence of those later be-
stowed upon the species, its synonymy being that here given.

Genus Melanomys.

Melanomys Thomas, Ann. and Mag. Nat. Hist., 7th ser., X, 1902,
p. 248. Type Oryzomys phizopus Thomas.

Melanomys was originally proposed by Thomas as a subgenus of
Oryzomys to embrace an aberrant group included by Bangs in the
genus Zygodontomys, but differing from the species in that genus by
wide skulls, especially between the orbits, and well-marked supra-
orbital ridges, a dark colored pelage, almost naked feet and hands,
and white nails. Dr. J. A. Allen, has reviewed the group (Bull.
Am. Mus. Nat. Hist., XXXII, 1913, p. 533) and raised Thomas'
subgenus to full generic rank, recognizing nine species and five sub-
species, ranging from the highlands of Nicaragua to northern Bolivia,
and eastward to Bogota and the region of the Sierra Nevada de Santa
Marta. In Central America two species have been recognized as
Zygodontomys chrysomelas and Z. idoneus which must hereafter be
included in the genus Melanomys. The first is among the species

W. Indies, F. C. M. Pub., VI, 1905, p. 191, Zool. Ser.
Dr. Allen (Bull. Am. Mus. Nat. Hist., VII, 1895, p. 116) rejected
Bachman's name of humulis for this species because it was not stated
in the description that the incisors were grooved, and therefore it

64 RHITHRODONTO.MVS.

could not have been a Rhithrodontomys. Mr. Osgood (/. c.) decides
against this view of the case because the original description, the
vernacular name "Little Harvest Mouse" and the colored plate
(No. LXV) all indicate a species of this genus, and not a Mus or
f\ ronyscus. It might also be advanced that as Bachman regarded it
as belonging to the Linnavin genus Mus, he probably did not look for
or perceive any generic character which might separate his specimen
from the genus in which he placed it, and the grooving was either not
noticed at all, or else regarded as of no especial consequence. The
evidence would seem to prove, however, that it was a Rhithrodontomys
he called Mus /tumults, and this was identical with the species found
on the eastern coast of South Carolina and Georgia, and that R.
lecontii (Aud. £ Bach.) must become a synonym.

Genus Cuniculus.

Cun ifiilus Brisson, Regnum Anim., 1762, p. 98. Type [Cuniculus]
paca Brisson.

Mr. Hollister in the Proceedings of the Biological Society of Wash-
ington, Vol. XXVI, 1913, p. 79, calls attention to this genus and claims
that the type could not be fixed by elimination, as was done by Dr.
C. H. Mcrriam, who made Cuniculus alactaga (Olivier) 1800, the type,
because Cuniculus cauda longissima Brisson which = C. alactaga
(Olivier) was placed in brackets as doubtfully referred to the genus,
and according to Article 30 of the International Code this makes it
not permissable, and therefore the type must be chosen by selection.
He therefore makes [Cuniculus} paca Brisson the type and accordingly
(.'unicidus supercedes Agouti Lacepedc, 1799.

Thr type of this species is in the Berlin Museum, transmitted there
by Deppe from Monterey, California. Mr. Osgood examined this
type specimen and was convinced that it was the same as Scalopus cali-
fornicus Ayres, which indeed it must be, as it is the only species of mole
found in that locality, therefore Ayres's name must become a syno-
nym, and the species be hereafter known as Scapanus latimanus
(Bachman).

This genus is accepted by Miller (List of N. Am. Land Mammals
in U. S. Nat. Mus., Bull. Smith. Inst., No. 79, 1912, p. 37), for Phyl-
lostoma bennctlii Gray, its only known species.

This species of Gray does not, however, come within the bounda-
ries of North America, but is apparently restricted to Brazil, an assumed
typical example having been procured at Ypanema, Sao Paulo, Brazil
(see Goldman, Proc. Biol. Soc. Wash., XXVII, 1914, p. 75). The
