The scientific publications of the National Museum include two
series, known, respectively, as Proceedings and Bulletin.
The Proceedings series, begun in 1878, is intended primarily as a
medium for the publication of original papers, based on the collections
of the National Museum, that set forth newly acquired facts in biology,
anthropology, and geology, with descriptions of new forms and
revisions of limited groups. Copies of each paper, in pamphlet
form, are distributed as published to libraries and scientific organiza-
tions and to specialists and others interested in the different subjects.
The dates at which these separate papers are published are recorded
in the table of contents of each of the volumes.
The series of Bulletins, the first of which was issued in 1875, contains
separate publications comprising monographs of large zoological groups
and other general systematic treatises (occasionally in several vol-
umes), faunal works, reports of expeditions, catalogs of type specimens,
special collections, and other material of similar nature. The majority
of the volumes are octavo in size, but a quarto size has been adopted
in a few instances in which large plates were regarded as indispensable.
In the Bulletin series appear volumes under the heading Contributions
from the United States National Herbarium, in octavo form, published
by the National Museum since 1902, which contain papers relating
to the botanical collections of the Museum.
The present work forms No. 194 of the Bulletin series.

AN ANNOTATED CHECKLIST AND KEY
TO THE AMPHIBIA OF MEXICO
By HoBart M. SMITH and EpwWARD H. TAYLOR
INTRODUCTION
A NEw era in the study of Mexican herpetology was initiated in 1932,
a year marked first by the appearance of Dr. Remington Kellogg’s
“Mexican Tailless Amphibians in the United States National Mu-
seum,”’ ! a work of fundamental importance; and second, by the renais-
sance of intensive field exploration in Mexico.
Since 1932 the number of amphibians in collections from Mexico has
increased about a thousand percent, and the number of recognizable
forms more than a hundred percent. For example, Kellogg recog-
nized 65 species of anurans, basing his study upon some 2,200 speci-
mens. We recognize 161, represented by collections totaling about
25,000 specimens. ;
The salamanders of Mexico have never been treated fully, although
Dr. E. R. Dunn’s “The Salamanders of the Family Plethodontidae,”’
which appeared in 1926, summarized over half the salamander fauna,
67 percent of which (by number of forms) is comprised by members of
the family Plethodontidae (as of today). Dunn recognized 15 forms
in 291 Mexican specimens; we list 43 forms, represented by some 9,000
specimens, and of all salamander groups combined 64 forms and 15,000
specimens. We are acutely aware that much revisionary work is still
to be done in Mexico and in adjacent areas. Several genera and species
obviously are polyphyletic assemblages; the study of some, like Rana
pipiens, is beset with the difficulties of tremendous variability, wide
range, and larger quantities of material than can easily be handled.
Satisfactory solutions to many problems await collections from critical
areas, and no doubt numerous species and subspecies remain to be
discovered and defined. Probably many of the forms we regard as
species will ultimately be regarded justifiably as subspecies. How-
ever, assumption of subspecific status for geographically separated
species (as we consider them) should be undertaken with temerity, as
witness the implications of Moore’s recent work by which some widely
1U.8. Nat. Mus. Bull. 160, 1932.
Z BULLETIN 194, UNITED STATES NATIONAL MUSEUM
differentiated species are shown to interbreed freely while other popu-
lations inadequately differentiated taxonomically are shown to be in-
capable of interbreeding. Furthermore, determination of the actual
status of some forms which we here regard as species must undoubtedly
await experimental investigation; we refer to extraordinary complexes
like that of a certain group of closely related but morphologically very
distinct species of Hleutherodactylus in central Veracruz (vide Taylor
and Smith, Proc. U. S. Nat. Mus., vol. 95, 1945, p. 572). Beyond
question, en fin, much juggling of arrangement remains to be endured.
This fact is a reflection of (1) the peculiar character of amphibians,
which are provided with fewer well-defined obvious and interracially
variable features than almost any other group of vertebrates, and
(2) the difficulties attending their collection. The difficulties of am-
phibian taxonomy are obvious to anyone who actually tries to identify
preserved specimens without the benefit of field experience. Knowl-
edge of the animals in life is practically indispensable even—or per-
haps especially—to the expert. This fact has not always been appre-
ciated by critics who may have felt that we have recognized, in some
cases, more forms than exist.
That thorough collection of amphibians is not easily attained,
especially in tropical areas, is well known. Some specimens emerge
from their quarters into the open for breeding, where they are more
easily collected, for extremely brief periods—perhaps one night a year.
Except in breeding congresses many species are rarely if ever found;
thus one must be on hand at just the right time and at just the right
place to secure the species. Salamanders are collected in abundance ~
usually by special techniques not widely applied, such as seining or
use of dipnets (for ambystomids) and search during the dry season
in bromelias, stump holes, ete. (for most plethodontids). We have
continually been surprised by repeated discovery of novelties at
favorite collecting sites that we had considered completely surveyed.
In view of these considerations, we feel that our view of the relative
incompleteness of our present knowledge and the considerable length
of time that will be required to approach completeness is not unwar-
ranted.
Nevertheless we feel the time is ripe for a summary of the amphibian
fauna of Mexico, the complexity of which has become steadily more
apparent in recent years. Students in this field have accomplished
reviewal of most available collections at least only in a preliminary
fashion, partly because of dwindling accessions during war years.
The coming years will undoubtedly be a period of review, during which
the activities of the recent past and the problems revealed by them
CHECKLIST OF THE AMPHIBIA OF MEXICO 3
will be subjected to individual attention at leisure. The present list
takes a step toward such general review by providing a brief survey
of the present status of Mexican forms and a concise analysis of recent
advances, to which additions and emendations may be made readily.
In preparing this summary we have followed, with some exceptions,
the style of our ‘Annotated Checklist and Key to the Snakes of
Mexico.” ? The present account differs chiefly in the natural arrange-
ment of the species and in the distribution of the keys, which instead
of being united are scattered through the list in appropriate places.
The keys are to transformed specimens, except where otherwise
indicated, since the larvae are too incompletely known to permit the
construction of useful keys. Likewise the eggs of relatively few
forms are known. Juvenile transformed specimens will not be
identifiable in all cases, since important characters may not be evident
in them.
For the sake of brevity we have indicated the E. H. Taylor-H. M.
Smith collection by the abbreviation EHT—-HMS.

6 In his revision of American caccilians, Dunn (Bull. Mus. Comp. Zool., vol. 91, 1942, pp. 487-540) unites
Dermophis and Gymnopis (under the latter name) because of the existence of apparently annectant forms.
The eye, visible and in an open orbit, is invariable in the three species of Dermophis but variable in visi-
bility and presumably in extent of enclosure by bone in the four species of Gymnopis. However, the posi-
tion of the tentacle (very near eye in Gymnopis, halfway between eye and nostril in Dermophis) does not
overlap, the extent of closure of the orbit probably does not overlap (not known for all forms), and finally
there is no indication that the present groupings of species under these two names are unnatural. For these
reasons we retain Dermophis.

14 Determination of the author of this name is perhaps an academic matter. Heretofore Wolterstorff has
generally been considered as the author, since he on page 132 of the same publication, in a separate article
“Zur Systematik und Biologie der Urodelen Mexikos” names and describes an “‘Ambystoma tigrinum subsp.
velascoi Wolt.’? Mowever, in an article (‘‘Untersuchungen tiber die Lebensgeschichte mexikanischer
Ambystoma-Arten”’) which precedes Wolterstorff’s Lafrentz (p. 105) cites the name ‘“‘Ambystoma tigrinum
velascoi subsp. n.”’ and proceeds to describe the race well enough to permit at least recognition and retention
ofthe name. Neither author, it may be noted, citesatype. Technically, for that reason, neither description
need be accepted, although we hesitate to follow the rules so Closely.
However, on page 145 a “‘Richtigstellung”’ states that ‘Ambystoma tigrinum velascoi subsp. n.’’ should read
“Ambystoma tigrinum velascoi Wolt.’’
There can be no question that the original proposal of A. t. velascoi isin Lafrentz’s article. We believe,
moreover, that he, not Wolterstorfi, should be regarded as the author—the correction on page 145 notwith-
standing—for the following reason. The description was, obviously, written by Lafrentz; the treatment is
much different from that which Wolterstorff gives, and there is no indication whatever that it isa quotation
from any ms. of Wolterstorff. Although it may be ‘clear from the contents of the publication that some
other person . . .” (i. e., in this case, Wolterstorff) “*. . is responsible for said name . . ”’, definitely it is
quite apparent that he is not responsible for ‘‘. . . its indication, definition, or description.’’ (All quotes
from art. 21, Intern. Rules Zool. Nomen.)

18 At least some of the several records of Ambystoma tigrinum from northern and northwestern Mexico
probably are referable to this race. Since, however, we have been unable to determine with desirable
accuracy the range of this or any other race of Ambystoma tigrinwm reported or expected from northern
Mexico we do not allocate the uncertain locality records.
16 We follow the work of various European taxonomists, including Wolterstorff and Herre, in segregating
American genera of this family. Evidence supporting such an arrangement has been gathered by the
exhaustive researches of Barbara Leonard at the University of Rochester and is in preparation for pub-
lication.

38 A specimen reported from Morelos, Guatemala, by Atkinson, Ohio Nat., vol. 7, 1907, p. 152, doubtlessly
belongs to another species.
89 There is a possibility that this species is the same as Hyla taeniopus Cope. Dunn, however, who ex-
amined the types of that species, reported that he did not believe they were Hyla beudinii but that it was
difficult to decide. Since Hyla bromeliana shows not the slightest resemblance to Ayla baudinii, the proba-
bility of its synonymy with taeniopus is remote.
40 Except for the testimony of E. R. Dunn and R. Kellogg (U. S. Nat. Mus. Bull. 160, 1932, pp. 170-171),
we would regard H. godmani as a good species with H. rickardsi a synonym.

STATE LISTS
Compilation of state lists is beset with difficulties arising from
incorrect or dubious identifications of material not now available for
examination. In most vertebrate classes, casual records and descrip-
tions frequently suffice to allocate correctly erroneously identified
specimens, but in amphibians even lengthy descriptions are sometimes
insufficient, if the proper comparisons are not made. More than in
any other vertebrate class, amphibians are identified, with exceptions
of course, on a comparative basis. Thus older workers, whose know]l-
edge of the Mexican fauna was far more incomplete than that of
present-day students, frequently could neither evaluate characters
properly nor describe them so that the specimens could later be
CHECKLIST OF THE AMPHIBIA OF MEXICO 101
identified satisfactorily. For this reason we have been unable to
allocate some published records, and others only with some or consid-
erable doubt. We have eliminated from these lists records we think
preposterous, but have retained some that are possibly correct even
though unlikely.
All political areas are represented by three or more records.
Arranged according to the number of species known from each, the
following sequence results:

Veracruz with 71 forms recorded possesses an extremely large
proportion of the species of Mexico. This is due perhaps as much
to relatively extensive collecting as to favorable environments;
important also is the wide variety of niches in the state. Oaxaca
with equally varied niches is not so well collected. It is of interest
that these two states lead also in number of snake species represented,
although the disparity between them is not so great for snakes. Arid
or semiarid areas inhabited by many kinds of snakes have relatively
few amphibians, as for instance in the case of Baja California. No
state has been really well collected, and most have been very poorly
investigated. Many additions are to be expected to the list as now
constructed.
