rHiLADELi'HiA, 'February 18, 1887. 

Dear Sir : I have the honor to present to you for publication among 
the Bulletins of the United States National Museum the manuscript of 
a general work on the Batrachia of North America. It embraces the 
results of a thorough study of the characters of the species, with their 
variations, which has been rendered effective by the very full collection 
contained in the National Museum, and which this work thus illustrates. 
Besides this descriptive part, I have i»resented the results of a thorough 
study of the osteology of the class, based on the material contained in 
various museums of the United States and Euri)pe. I have expressed 
these results largely in systematic form, in the belief that descriptive 
zoiilogy will never be complete until the structure is exhausted in fur- 
nishing definitions. Wherever practicable, reference is made to the 
relations between the extinct and living forms. 

I have been greatly indebted to you for the use of the manuscript 
l)re])ared by yourself and Dr. Girard many years ago with such a pub- 
lication as the present one in view. Of the descriptions of the fifty- three 
Urodela, nineteen are from your pen, and of the forty-seven Salientia, 
twenty-t)ne are the work of yourself and Dr. Girard. This has materally 
lightened my labor, the only additional work necessary to these descrip- 
tions being such as increase of material has recpiired. In the same way 
the figures of the external characters of the Urodela of which your de- 
scriptions appear in the text, were prei)ared under your direction, and 
the drawings of the crania of the same Urodela were partially prepared 
at the same time, and have been completed by myself, now appearing 
for the first time. The other drawings were made by myself, excepting 
some which are credited to others at the proper places. 

Besides the collection of specimens in alcohol, the collection of skele- 
tons prepared by yourself, and now part of the National Museum, has 
been of the greatest service in the preparation of this work and of the 
various papers by myself which have preceded it. 
I am, with much respect, yours, truly, 



Prof. S. F. Baird, 

Secretary of the Sniithsonian Institution.

THE BATRACHIA OF NORTH AMERICA. 



! 



BATRACHIA. 

Bonguiart, IdOO. Amphibia Latreille, 1825 (not of Linnsens 176G). 
OKNEllAL CHARACTERS. 

Vertebrata witb a ilistinct coracoid eleuu'iit of the scapular arch and 
with an os quadratutn. The limbs consist of a single proximal element, 
two propodials (sometimes united), a carpus and tarsus, metapodials, 
and phalanges. The cartilage of the basis-crauii unossified (except some- 
times a basioccipital ossilication), but supported by the single mem- 
brane bone, the parasphenoid ; vertebral column consisting entirely or 
in part of intercentra. Stapes present. 

Brain with the cerebelhun small, and the mesencephalon smaller than 
the prosencephalon ("hemispheres"); the latter with the ventricles on 
the inner si<le of their principal mass. 

Heart with three chambers, two auricles, and a ventricle. Three or 
four aorta bows on each side. Lungs always present. 

Gall-bladder and urinary bladder present; oviducts entirely distinct, 
and opening by Ibntanelles into the abdominal cavity at a distance from 
the ovaries. Reproductive, renal, and digestive products discharged 
into a cloaca. Male without distinct intromittent organ. 

In development the embryonic life is prolonged during a period of 
freedom subsequent to leaving the egg, constituting a larval stage. 
J)uring this period the young is branchiferous and generally aciuatic in 
its habits. No amnion nor allantois. Segmentation of the yolk complete 
or holoblastic. 

GENERAL ANATOMY. 

The auditory organs resemble those of other terrestrial vertebrata, 
and (litter from those of fishes, in the presence of a fenestra ovalis of 
the internal ear, which is closed by a stapes. The other ear bones or 
their equivalents are fused at an early stage of growth with the sus- 
ponsorial cartilage of the lower Jaw (Parker). There are three semi- 
circular canals, but the helix is represented only by a diverticulum of 
the sacculus. 

The hyoid apparatus is less complicated than that of the I'isces, and 
more so than that of the vertebrate classes above them in the series.

There are always a .listiuet so-oalle.l ceratohyal ; one ov moroaxia ele- 
ments or basibranchials, aiul lateral pieces, or oeniiol.rancliials. liere 
is no glossohyal. Further than this nothing can be said of the class, 
as the orders' dilVer anion^' themselves in the details. 

In the carpus and tarsus there is always an os ccntrale, except in the, 
tarsus of the Salientia. In the extinct Carboniferous yenera Evyops' 
an.l Archcgosaurus.- there are two centralia in each foot (/>c.v ot Eryops 
unknown). The intermedium is either present or fused with one of the 
adjacent bones of the tirst row. There is a series of carpalia and of 
tarsalia, pviny attachment to tlie met.'podials. whose nund)erand con- 
dition ditfer in the dilVerent families, im' number of di-its is -onerally 
not more than four in front and live behind. There is very often a rndi- 
mental thumb on the anterior foot in the Salientia, and in the extinct 
rhaehitomous jienus Eryoi)s there are live \vell-devcl(.i)ed dijiits on the 
mauus. (Plate 1'). tiy'. 1.) In the .Salientia there is often a rudimental 
sixth toe internal to the liallux. ( Plate 07-Si.) 

The shoulder-f,nrdle is not connected with the skull in the P.atrachia, 
excepting in the genus Ilemisns. There is a large suprascapula. The 
osseous coracoid is of various proportions, and it has various cartilagi- 
nous extensions, as epicoracoid and procoraconl. These are ossilied in 
some of the extinct forms. There is much variety in the pieces which 
occupy the middle line of the scapular arcii. The (uders may be ar- 
ranged as follows on this basis : 

An t'liisti'niuin amino sternum: UnnonphnUt. HhiuJutnuii 
An oniosternnni and stenmni ; no ciiistfrniiin. SaVuntm. N- 
Triichjintohuita, I'vote'ula, rrodtla (fxcejit TniiKitiiditui). 

The pelvis is always fiu'iiished with an ilium, but the pubis is want- 
ing or represented by rudiments, except in the extinct forms, where it 
is present. The ischium is i)riniitively an undivided cartilaginous plate. 
Xo obturator foramen. There are some characters which are common 
to all or nearly all Ijatrachia. but which may be found on further knowl- 
edge of the extinct forms not ro have been always present. One of 
these is the continuity or fixed articulation of tlie quadrate cartilage 
or bone with the skull. The proximal part of this bone is intercalated 
between the squamosal aii:l exoccipital. and the i»terygoid when present, 
so as to i)resent only its distal extremity free. In the Salientia it is an 
insignifleant element, being generally cartilaginous. 

The vomeroi)alatine bones are always double, except where wanting, 
which is only the case in the Trachystomata. They are nearly always 
deutigerous. 

The orbitosphenoid bone is always well developed. 

In the existing orders the atlas is undivided. I have put forth the 
hypothesis^ that the vertebral bodies in the existing and most of the

THE HATRACllIA OF NOliTH AMERICA. 



k 



extinct onlcrsot' Uatnicliia are not th« centra of the higher vertebrata, 
but are intercentra, w hidi are occasionally seen in the higher vertebrates 
in a rudiniental condition. This is especially the case in the remark- 
able saurian of New Zealand, the Si)henodon, and in the extinct order 
of the Theroniora. Owen has shown that the mtcrcentra exist also in 
the mole. I have given the following reasons for this view: 

1. The intercentra are very large in the Ganocephala and KhacUi- 
tonii. 

, They support the neural arch in the Enibolomeri. 

J. They are not rndimental in existing Batrachia. 

4. The chevron bones, which originate from the intercentra of Kep- 
tilia, are continua with the caudal vertebral bodies in Iiatrachia, 

.J. Tlie ribs, which originate from the intercentral cartilages in Kep 
tilia, originate from the vertebral bodies of Batrachia. 

Tiie paleontology of the Batrachia and Beptilia shows that the order 
Enibolomeri is tlie only one with complete vertebral bodies, and so 
probably gave origin to the reptiles; while the intercentra in some 
Batrachians become so connected with the neural arches as to lead to the 
belief that they become the vertebral bodies of later forms of the class 
whii'h JMve <lescended from them. 

In a'- the orders, genera with well-developed antericu' limbs display 
well-developed distal condyles of the liumeru: . They are better de- 
veloped than ill any order of reptiles, with the exception of the Thero- 
niora. 

With regard to the cranial nerves, it is to be remarked that the latera- 
lis brancii of the vagus is present, as in fisiies; also that the glossopha- 
ryngeal is united with tlie vagus. In the Urodehi the nervus facialis is 
distinct from the trigeminus (Fig. 1), but in the Salientia they are 
united. (Plate 4.S.)

In the museular system the Batrachia diifer from the fishes in the

,s of all tlH- tailed orders, and are transient in the 



the caudal regioi 

tails of the larva- of the Salieiitia 




Ki-niainsof tliesaiiieare seen in the 
segmented dorsal uniscles of the Uro- 
dela. and the segmented median ven- 
tral, or pnbosternal muscles of the 
tailed and tailless orders. Between 
these median series of muscles extend 
two layers, which suitport the sides 
of the body cavity, the external and 
internal oblique. Jn the Urodela the 
oxteiiial oblique is divided up at the 
superior border into separate heads, 
each of which arises from the extrem- 
ity of a rib. Between the ribs is a 
band of narrow longitu linal inus- 
oU'.s—theintercostal.s— which are par- 
allel to the doisal muscles. Owing 
to the modilieation of the skeleton 
the dor.sU niu.><cles in the Salientia 
are much nioditied, and form chev- 
rons with the apex posterior. The 
limb mu.scles are much like those of 
higher vertebrata. _ 
The heart of the IJatrachia pos- 
sesses three chambers, two auricles and one ventricle, and there is a 
sinus venosus at tlie entrance of ::he vena ca\ a. The bull)us arteriosus 
is not uuiscular, and has a longitudinal valve or partial septum, or is 
completely divided into two in the Proteida. In the Urodela there are 
four aortic branches on each side, whieh are in the larval state branchial 
arteries. As many veins return from the branchia' and unite above the 
heart to form the aorta. In develo])inent to matr.rity the arteries be- 
come connected with the veins by longitudinal vessels, the tluctxs hotaUi, 
which complete the ''aorta bows" where the oranchial system disap- 
pears. The first and last of these arches become subordinate, and 
the intermediate on each .side function as "aorta roots," who.se union 
forms the aorta. The carotitl artery is a coritinuation of the (hii'tui^ 
hotaltl «onnecting the first and .second bows, and the last bow is modi- 
fied into the imlmonary vein. In the Proteida and Trachystoniata 
three aorta bows remain on each side, and the branchial arteries and 
veins jiersist. In the Salientia three aorta bows remain, but the second 
on each side only form the aoita, the first and last forming the carotitl 
artery and pulmomiry vein. 

The venous system consists primitively, as in other vertebrata. of 
two anterior and two posterittr cardinal Aeins, which unite on eacii side 
into a single transverse vessel, the Diicfus '.'uvieri. which empties into 
the sinus venosus. Subsequently two otlier pairs of longitudinal veins

arise parallel to the cardinal veins, and empty into the anterior cardi- 
nals on each side, in front of the JJtictus cuvicri. These are the verte- 
bral veins. The portion of the posterior cardinals between the Ductus 
cuvieri and the kidnej' disapi)ears, so that what remains of the pos- 
terior cardinals are only renalen advehentes. The anterior cardinals 
become the jugulars. The i)rincipal posterior vein is the vena cava pos- 
terior^ which is median, and consists originally of the renales rerehentes 
from the kidney. It receives the hepatic vein before emptying into the 
sin us veuosus. The iliac veins pass directly into the kidney after re- 
ceiving the V. catidalis. 

Till' lymph cavities of the body in the Batrachia are extensive. This 
is especially tlie case witli the Salientia, where the skin is loosely at- 
tached, and incloses large spaces immediately below it. The lymphatic 
vessels from the digestive system open into these cavities. The ves- 
sels also empty into the veins, and present at such points enlargements 
which contract rhythmically, and are known as " lymph- hearts." They 
are situated in the sacral region, one on each side, in the tailed forms, 
while an additional jiair is present in the sciapular region in the Sali- 
entia. 

The reproductive and urinary systems are closely connected in the 
Batrachia, and must be treated of together. Both discharge their con- 
tents into the alimentary canal, forming a cloaca. Their structure is 
best understood by reference to that of the sharks. In these fishes a 
primitive longitudinal vessel on each side of the dorsum of the abdom 
inal cavity sends branches to the outer side, which there form convo- 
luted lobules, the primitive kidney. In the Batrachia this longitudinal 
or archinephric duct divides longitudinally, and the inner portion re- 
mains as the Miillerian duct. This becomes the oviduct of the female. 
The external half with its series of branches becomes the urogenital 
duct. The testes and ovaries are developed independently external to 
the kidneys, and the former send their efferent ducts directly into the 
latter. The ovaries discharge the eggs into the abdominal cavity, 
whence they pass into the oviducts by the free open extremities of the 
latter, and are thence ejected by the anus, after receiving a covering 
of albumen. The male organ homologous with the Miillerian duct is 
of reduced size in all tiie Salientia except the Kana' and allies, where it 
is aborted. It has been shown, however, to persist in our Bana rirens. 
In the Urodela the vasa deferentia pass through the kidney and enter 
the genitoiirinary duct, and so into the cloaca ; but in the Salientia the 
efferent ducts of the kidney collect themselves into a separate tube or 
ureter, \vhi"jh, however, joins the single vas deferens before entering 
the cloaca. But the Discoglossid* agree with the Urodela in this, as 
in several other resjiects. A urinary bladder is always present in the 
r>atrachia. The testes are single on each side in the Salientia; there 
are several in the Urodela, esi)ecially in the Ca.'ciliidre. The penis is 
wanting. Impregnation is accomplished by copulation in the Urodela,

but iu the Salientia the sperinatozoiii.ls are dischar-e.l o.i the ova after 
leaving the bodv pf the female. (Plate.s IS, ll>, ;W. 4J.) 

The aliinentarv canal iu the Batraehia is .simple, since it is not highly 
specialized into distinct parts. The liver is larse and is <livided into a 
varying number of lobes, which are esi)ecially numerous, and arranged 
like a roll of coins in the Ca'.-iliida>. The gall-bladder and pancreas 
are present. The teeth are not implanted in alveola-, and are iu the 
recent forms more or less pleiirodoiit. 

LAKVAL CHARACTEKS. 

In the course of the growth of a batracjhian there is always a period 
which follows the freedom of the embryo, in which there are structures 
tor securing respiration in the water. These gills difler from those of 
fishes, in that the fringes in which the blood is aerated .stand on lieshy 
processes of the branchial arches, and not directly on the arches them- 
selves. Similar structures are found in the preliminary stages of 
some tishes. During this stage the tail is more or less modified as a 
swimming organ, and the condition of the skull differs materially in 
character from that of the adult. In the tailless or anurous Batraehia 
the limbs do not appear until this period has nearly closed, while in 
the tailed or urodele order the liml)s api)ear almost immediately after 
the gills. Besides these transitional characters, the Urodela possess in 
their early larval condition a long process in front of the first gill on 
each side, which is termed a balancer. This remains in a few abnormal 
cases in salamanders, but is permanent in the suborder of the ea'cil- 
iaiis or worm-like >>atrachia. A similar process exists in the larva of 
the frogs of the genus Xennpu.s: whi'-h resembles superficially a siluroid 
fish ; but in the Salientia generally tnc balancers are wanting. 

Tlie gills in the Salifiitia (frogs, toads, etc.) are soon concealed by a 
growth of the skin, which leaves a small orifice for the di.sciiarge of 
water from the i)haryngeal cavity. In one group of these animals this 
opening is on the middle line l)elow, but in the great majority it is 
single and is situated on the left side. 

The changes undergone by the skull in the metamorphosis are much 
more important in the Salientia than in any other order, and are treated 
of under the head of that order. 

The eggs of Batraehia are always deposited in the water or in damp 
places. In a few instances the young do not seek the water, and iu 
one species (Salamandra atra) they are born free from the egg. 

Under the head of the Salientia will be found a table of the various 
modes in which the eggs and larv.-e of those animals are deposited and 
cared for prior to maturity. 

Under the respective orders the descriptions of their characteristic 
peculiarities of development will be found. (IMates 30, 11, 78.)

THE BATRACHIA OF NORTH AMERICA. 13 

CLASSIFICATION. 

There are several orders of Jiatrachia, and they disi)lay remarkable 
diversities of skeletal structure. For the better understaudiug of these 
I give the following table of their principal definitions:' 

I. Basioccipital, supraoccipital, iutercalaiy,- and supratemporal lioues present. Pro- 

poilial boues rlistiuct. 
a. One cotyloid occipit.al condyle, 

Vertebral centra reidaced by one basal and two lateral elements 

witli one nenral arcli GimoceiihaUi. 

aa. Two occipital condyles. 

Vertebral Viodies, including atlas, segmented, one set of segments 

togt*lier suppcrting one arch L'hachitomi. 

Vcrtebr.T segni< nted, the superior and inferior segments each 

complete, forniini; two centra to each arch Emholumeri. 

Vertebral bodies, including atlas, not segmented: one to each 
arch Sttgocephdli. 

II. Basioccipital, suiiraocciiiital, and supratempi>"al bones wanting. Frontal and 

propodial bones distinct. 
a. Au OS intercalare. 

A palatine arch and separate caudal vertebra? Prottida. 

aa. No OS intercalare. 

A maxillary arch and vomers; palatine arch present, imperfect; 

nasals, iiremaxillaries and caudal vertebne distinct Vrodtla, 

No niBxillary or palatine arches; no vomers: .lasals and pre- 

maxillary. also caudal vertebra*, distinct. Trachi/'stumata. 

III. Basioccipital, su])raocci))ital, intercalare. and supratemjioral boues wanting- 

Frontals and ]>arietals connate: proi)odial bones and lumbosacral vertebra^ 
each continent. 
Palatines distinct from vomers; a palatine arch : a.stragalus and 
calcaneum eloiiy,ate, forminu a distinct segment of the limb Salientia. 

The animals of the liivision I are all extinct. Division II includes the 
Salamanders and their allies, witii the worm-like C<ecilians (Aj>oda), 
while the third division embraces the frogs, toads, etc. 

AFFINITIES. 

The Batrachia are, tlien, intermediate in characters, and therefore iu 
position, between the tish-like forms and the reptiles. Among the 
former the Dipnoi ai)pi'oacii tliem most nearly, while the extinct reptiles 
of the oldest order, the Theromora,^ are the nearest allies on the rep- 
tilian side. It belongs to the series of vertebrates which have a dis- 
tinct coracoid bone in tiie shoulder-girdle, ami a distinct quadrate bone 
in the skull. The greater part of the basicranial axis is cartilaginous, 
but it is protected below by the membrane bone, the parasplienoid. In 
all these respects, and in the absence of an amnion of the embryo, the 
Batrachia agree with the fishes. They differ from tiiischissin the jtres- 
ence of legs and absence of fins, and in the absence of various bones 
whi(!h belong to the l)rauchial and opercular .systems, and to tin- sus- 
])en,sor of the lower Jaw.

Thii ('liariicters display-'d l).v tin? three divisions in question indicate 
their rehitionship to l)i'. iis Ibllows: The orders of JJivision I ])resent in 
their cranial structure a greater resembhiuce to the limblinned or 
cro8soi)ter.> siiHi iishes tlian do either of the others. The third division 
is the most divergent from tiie t.vi»y, and is in various respects tlie most 
speciaHzed. This si>ecialization consists not only in a departure from 
the i)rimitive Batrachia, but also from all other forms of vertebrata. 
Its specialization is seen in the loss and cocissification of various parts 
of the skeleton. The ITnulehi display chara(;ters interme<liate between 
the extremes of the class. Near them the Trachystomata (SirenidaO are 
still more inferior by loss oi' parts of the skull ami of the pelvic arch. 
The Prnteida have lost the maxillary arch of the Stegocei)haIi, but re- 
tain their OS iiitercalare. 

IMIVLOGENV. 

The class IJatrachia holds an imi)()rtant position in the history of the 
vertebrata, as tlie first meudter of that kin;;dom which occupied the 
land on the advent of the conditions suitable for air-i)reatbiny types. 
It thus stands in ance.stral relation to the lines of the Sauropsida and 
^lammalia, and as the immediate descendants of the fishes. As rej^ards 
the extinct orders, the primitive type is evidently the (ranocephala. 
whose vertebral column displays an arrest of (diaracters which are 
transitional in the hij^aer vertebrata. From this group the orders 
ithachitomi, Fauboloi'ieri,and Ste.nocephali have been evidently derived. 
We may then present the followinj,' fjenealogical table of the class 
liatrachia : 



Salieutia.

As regards the connection of the class, as a whole, with other classes 
of vertebrata, it 's very probable that the extinct orders, as the Gano- 
ceiihala, were denveri ♦roiu some extinct form of Dipnoau fishes, more 
or less related to the group of which the genus Ceratodus is a represent- 
ative. In this type we have a persistent chorda dorsalis, fins which 
present the type from which ambulatory limbs were derived, a pelvis, 
and a cranium nearer that of the batrachians than most other fishes 
pre.-^ent. The Crossopterygia are a little on one side of the parental 
stem, since they have no pelvi.^*, and their limbs begin to show a begin- 
ning of that reduction and specialization which is carried to such an 
extent in the Actinopterygia, or typical H.shes. 

From the Ganocepiiala we derive the remaining orders, all of which 
possess two occipital condyles. The intercentra, which are small in tlie 
prepel vie vertebral axis of the Ganocephala, assume a large development 
in the Embolomeri, wbich thus have two bodies to each neural arch 
throughout the series. It is probable that the reptiles took their origin 
from this grouj) by the gradual reduction of the intercentra, and the 
continued dominance of the centra. It is possible also that the Em- 
bdloi eri possess but one occipital condyle, which, uniting with an in- 
tercentrum, formed the single occipital condyle of the Reptilia. 

In the direction of the lihachitomi there is reason to believe that the 
intercentra became predominant in the vertebral axis, and that th^ 
centra soon disappeared. This order gave origin to the Stegocephala, 
in which the centra are wanting; and this order was the .source of the 
Proteida on one hand, and the Salientia on the other. The formei', of 
all the existing orders is the only one which retains the os intercalare 
of the Pahvozoic types. From the Proteida we get the Urodela, and 
from the latter the Trachystomata, as will be more especially shown 
under that order. 

The Ganocephala (Trimerorhachis) and the Rhachitomi (Zatrachys) 
had a well developed columella auris, which extended from the lieuestra 
ovale and turned upwards and backwards to the notch of the posterior 
outline of the skull between the os intercalare and the base of the quad- 
rate. It is highly probable that this notch was occupied by a tympanic 
drum.' In the Proteida, Urodela, and Trachystomata, there is no col- 
umella. In the Salientia there is a chain cousistiug of one bone and 
two cartilages extending between the stapes and the memhranum tym- 
imni. Thus the LTrodela in this resi)ect have undergone degeneration, 
while the Salientia have undergone specialization. With regard to 
other parts of the skeleton all the later and recent orders must be re- 
garded as having undergone degeneration, in view of the extensive loss 
of parts. (See Origin of the Fittest, by E. D. Cope, On the Evolution 
of the Vertebrata, progressive and retrogressive.)

EXl'LAXATIOX OF TERMS. 

The Canthns rostralis i.s the ridge more or les.s defliied which marks 
the Hue of separation anterior to tiie eyes, between the toi) and side of 
the head. The outer uarcs or crtenml )iost)-ils are situated in or a little 
below this angular line, and between the eye and tip of suout. The 
Cauthtis orhitalis is the corner of the eye, either anterior or posterior. 
By ramus of jaw is meant either of the two branches, one on each side. 
The rictus is the point of junction between the upper and lower Jaws. 
The eomniissure is the line along which the two jaws meet when closed. 
The internal nans or ehoana' are in the roof of the month a little ante- 
rior to the eyes. The Eustachian apertures, or ostia pharyngea, are sit- 
uated very far back in the roof of the ntoutli near the end of the jaw, one 
on each side. The angle of the jaw is just behind the point of articula- 
tion of the two jaws. The concealed surfaces of the body are those which 
are internal and j)ressed against each other when the limbs are tiexed. 
The teeth in the roof of the month are vomerine or vomeropalatine when 
they are within or near the inner nares, and on the bone of same name; 
and they are parasphenoid, or \oo%e\y, palatine, "hen considerably be- 
hind the level of the inner nares and placed on the i)arasphenoid bone. 
The enumeration of the fingers and toescommences with the inner ones, 
the fourth finger and the fifth toe being the external. The term finger 
always belongs to the anterior extremities, and toe to the posterior. 
The phalanges are numbered from the metapodial bone. By articula- 
tion is understood the hinge between two adjacent bones, which them- 
selves are called segments. The tympanum or membranum tynii)ani 
is the circular disk seen on each side the head, posteriorly and just 
back of the eye, in the Salientia.

NOMENCLATURE AND HISTORY. 

By Linnaus, in the tenth edition of the Systema Natunv (1760), in the 
twelfth (17GG), and in the thirteenth (1788) reptiles and batrachians are 
included in a class "Amphibia." The two classes were not recognized 
even as subordinate divisions of the Amphibia. These divisions were 
the Reptiles, Serpentes, and Nantes. The last named included only 
fishes. Four genera were included in the reptiles, one of which was 
Rana, which embraced all the Batrachia Salientia. The Urodela were 
enumerated as species of the genus Lacerta. The genus Cecilia was 
placed among the berpeutes. 

Laurenti, in the Tentamen Systema Reptilium, 17G8, first used the 
class name Reptilia for a combination of the two classes, Rei)tilia and 
Batrachia, as at present recognized. Ue proposed three orders of 
Reptilia, the Salientia ( = Batrachia Anura), the Gradientia (= lizards 
and Batrachia Urodela), and the Serpentes, in which he included the 
Ccecilias.

LntrciUe published a system of Keptilia in tho Nouveau Dictionaire 
d' llistoire Naturelle in ISOi, Vol. xxiv, paj^'e (Jl. lie adoi)ts the sys- 
tem of Ilrongniart. The Batrachia are divided into two sections: I 
/>. (vurcurs, aiul 1 1 li. pisciforuics. The secoiul section included the gei;- 
era Proteus and Siren; section I, all other Batrachia known to the 
anihoi'. In l.S2r> Latreille published another classification iu the bro- 
chure "Les Families Natunlles du Hegne Animal." lie divides the 
vertebiata into warm-blooded (llaemathermes) and cold-blooded (llae- 
maerymes). The latter include Pulmonees antl Solibranches. Tiie lat- 
ter includes the lishes. The Ibrmer division has two subdivisions, Wep- 
tiles and Am|)hibia or Batrachia. We here find the system of Do 
IJlainville adoi)ted in the reco;;nition of the Batrachia as distinct from 
the Keptilia, and the na!;ie Amphii)ia is used for it for the first time. 

Daudin in l.SO'.'-Hl.'i ])ublished his Trait6 (ienerale. He adopted the 
classifu'ation of Brongniart. 

Dnnieril, in ISOt, in the Traite elementaire d'histoire naturelle, also 
adopted the system of Bron<;'niart. He placed the Cu'ciliidie among 
(he Ophidia. In his ZoiUogie Analyti(pu', published in 1807, he followed 
I he same arrangeuuMit, and divided the Batrachia into Auura and Uro- 
dela. The latter included four genera: Triton, Salamaiulra, Proteus, 
and Siren. 

lAtnitirck, in 1S()!>, published a Distribution (ien«''rale des Auimaux, as 
I he (chapter viil of the Philosophie Zoiilogique. He did not distinguish 
the Batrachia from the Keptilia as a class, bat recognized the four 
orders of Kejjtilia already proposed by P>rougniart. The Batrachia are 
divided into two divisions: Urodelii and Anura. (Jcecilia is placed in 
the serpents. 

CkvIck, in the Le(M)ns d'Anatomie Comparee, in 1801), and in the 
Kegiie Animal, in 1817, adopteil the system of Jirongniart. In the 
si'cond edition of tlie lattei', pul»lished in 182!) he divides the Batrachia 
into live genera, vi/ : C(ecilia, Kana, Salamaiulra, Proteus, and Siren. 

Opjxl published his "Ordnungen Familien u. Gattungen der Kep- 
liiien" in 1811 (Munich). lie adopts the class name llei)tilia, and 
divides it into three orders : Testudinata, S(piainata (snakes and lizaids), 
and Xiida or Batrachia. The Batrachia are divided into three families ; 
the Apoda (('(cciliida), ICcaudata or Aniira, and the I'rodela.

N itiiralist), two orders were added, tiie Kliachitomi and Kmbolomeii, 
linth extinct. In the "Origin of tiie Fitti'st" (Philadelphia, ISSO) still 
another order is added to the IJatraiiliia, the (Janoiu'phala of Owen, and 
t 111 (iymnopliiona((J(et;iliida')are united with the IJrodela, makiiij'- eight 
oi'ders in all. Tliis systiMii is adopted in tiie iiicsent work. In 18(15, in 
•I paper on the Primary J)ivisioiis of the liatrachia Salientia (Natural 
History Ileview) the .Vniira were divided into Ajjlossa, |{iifonitbriiiia, 
AKtifera, and Itaniformia. These divisions arc here adopte«l, except- 
i:i,u the Ibifoniformia. 

Ilii.tlcj/, AnatDiny of Veitebratcd .\niinals, 1871, «livides the vertL!- 
Iir.ilainto hditliyopsida, Sauropsida, and Mammalia. The Ichthyopsida 
correspond to the Anamniaof Ilaeckel, plus the Leptocardii and Mar- 
sip(»hiancliii. This division is divided into two classes, the Pisces ami 
AaiphiUia (Hatrachia). The Keptilia and Aves form the Sauropsida. 
The An;pliibia emlnace, according; to Iliixley, four orders, viz : Uro- 
dcl.i, lialiyrinthodonta, Gymiiopliiona, and liatrachia or Aniira. The 
trodela are divided into J'roteida and 8alaniandrida, which corro- 
spmid to the Trematodera and Vitretodera of Dumeril and iJibron. 
Professor Ilnxley j,'ave the (irst (dear osteoIoj;ical delinition of the class. 

<ie(jcnh((in\ in the Elementsof t!omparative Anatomy, 1872, follows the 
system of Ilaeckel so far as rcf^ards the higher groups of vertebrata. 
The Uatrachia are called Amphibia, and have the three divisions pro- 
liosed by Merrem, but under the names Urodela, Annra, and Gynino- 
pliiona.

of this book, I lind the following to be the names to be adopted. I find 
that Ihongiiiart first perceived the correct limitation of the iJatratdiia, 
and that in 1S(M) he gave it that name. In this he was followed by La 
treillein ISOt: by I)audin,in ISOL*-.'); by Dnineril, in ISIU ; by Lamarck, 
in 18l»l>; by ('avier, in 1801) and in 1817; by .Merrein,in bSliO; by ilarlaii, 
in 1825; hy Dumeril and Hibron, in 1811; and by various modern writers 
since that date. The name Amphibia I find first used by Dc r.lainvllle 
in 181(5 as intcn^hangeable with the name Xiidipellifcri, and also as a 
siibili vision of itself eipial to the I'eiennibranchiates of somk; later au- 
thors. The name is first definitely adopted by liatreillein ISL'o, a^jnar- 
ter of a century after the introduction of the name IhUrachia. lie is 
followed after a long interval by Ilacckel in 18(!(!, who, howexcr. uses 
the name Amphibia as interchangeable witli IJafracliia. It is ex(du 
sively used by Ilnxley and by (legenbaur, and by a number of modern 
naturalists, chiefly anatomists. From the ab:)ve record it is (inite evi- 
dent that the proper name for this class is Matrachia. 

The true classification of the (contents of the (dasa wa.s of much later 
discovery. The tailless division was recognized, it is true, by the earlier 
authors: and, first of all, in 17(!8 by Laureuti. who called it the Salient ia 
audgaveitadeUuition. This naniL' must be therefore retained. The di vis-

The divis- 



ion of true Siilaniaiiders was not properly (list in.uuisheil before the pub- 
lication of the system of De IJlaiiiville, in 1S1(5, who eillcd fiieiii the 
Pseiidosaiiriii. lie, however, omitted from them the Ca'i;iliida'. In this 
:)iiiissioM ho was followed by rll siibse(|iieiit authors, except Cope, who 
called the entire order, iiicliidin.!;' tlie(%ec.iliida', the IJrodela, a(loi»tiiij{ ii 
name already proi>osed by Dumeril, in IHOt, for a division of wider 
scope. On this a(!(!ount the name irrodola is ailopted in the present 
work. The iiaiiu' (irradientia was (irst used to iiniliide only Uatiachia, 
without lizards, by Merrem, in ISUO. The two branchiate or.lers, I'ro- 
4ei<laandTiMehyst()mata, wereinduded in the IJrodela or (liailieiitia by 
all authors except the followinjf: J)e IJlaiiiville combined them in one 
(uder, the Amphibia; Gr.iv, Iliirlan, and Fitziiiger followed, but com 
billed them with uiirelat'd foriiH; Dumeril and IJibron kept them to 
{^ether with t!ie Crypt )branchida' in a division, Trematoderos, follow- 
ill};' Fitziii}"er (ISLMi); Haeckel follows De IJIainville, but renames the 
I'seudosaiiria of that author Sozobranchia, and includes in his Am- 
phibia the noil related Axolotls, In ISIJIJ* Cope lirst distinjjjuisIuMl tiic^ 
'rrachystomata and I'roteida as orders, and pureed them of the Axolotls, 
which he i»laced in the Crodola.

This order aji'rees j^fenerally with the Urodela, but i)roscuts one most 
important feature of dilVereiKU', in the presence of theOs intercalare. It 
is this point that yives the Troreida its position between the Stejjo- 
cephali and the Urodela, and which indicates the line of conneetion 
betw( ". the extiiKtl forms of the Carbon iferou.< period and the mod- 
ern t^> pes. 

The hyoid apiiaratus dillers from that of adult Urodela, and resembles 
their larva; in liaviii;;' three e[iibranehials, instead of one only. The 
second basibraiicliial is also eonneeted with the first, which is not the 
(rase with the Uroilela. Thi' centrale is present iii both carpus and 
tarsus. 

No extinct <;euei'a are certainly known to belong to this order, but 
there is one that n'sembles it nearly, and may belong here. This is tiie 
('ocytinust (Cope), which has been found in the coal measures of eastern 
Ohio. If it be not a larval Stegocephal, it belongs to this order. It 
would not enter the same family as the recent forms, as it has a small 
maxillary bone. Another extinct type from the Wealdoii of IJelgium 
has been suspected to belong to the Troteida, but the cranium is not

Of tliesi' Xecturus is Xi)rth Amerie.ia ami Proteus is ICuropMii. The 
hitter is represented by three or foar spuiies, which live in subterr.inean 
waters in the southern parts of Austria. 

These genera dilVer soaiewhat in the hyoid apparatus. The hypo- 
hyal is present in NVeturns, but is, aecordin.i;- to Wiedersheiui, wantin;-' 
in Proteus, in the fornuT the second cer.itobrani^hial is much smaller 
than in the latter, and is not onnected with the b.isibranchials. 

The connections between the inferior arjlie-s and the skull iU'o inter- 
esting. In Necturus the columella is osseous and is bent abruptly for- 
wards, and articulates with a short p )sterior process of tiie sifiiauiosal 
bone. The ceratohyal is free fr.)m the skull, luit is cDuni'ded with it 
by tlie two ligaments, the hyosusi)enso/ial to the middle of the (]uudral»», 
and the niandibuhdiyoid, to the angle of the I'.andible. (IMale IS, fig. 
1.) la Proteus (Pig. 2) the arr,iii.,'einiMit is similar, cixcepr that the 
processes of the stapes and s(iiiamasil do not meet, bat are connected 
by a strong ligament. 

The intermedium of the carpus and of the tarsus is eonlluent with 
the adjacent external element, tlu^ uluare and the libulare. Tliere are 
three carpalia and three tirsalia, the internal on the inner side !" the 
carpus and tarsus. Tlie carpus and tarsus are thus very nuieh alike.

In this si»ecies the body is only moderately elongate, measuring, with 
the head, four and a li;iU' to live times the f-reatest width of the latter. 
The body is deiiressed, though not so much .so as that of thi> known 
sju'cies of Cryptobranchus. The section of the tail at the ba.se is a ver- 
lical oval ; beyond this point it is more compressed, so that the distal 
half is Hat and oai'-like, with a wide dermal border above Jiud below. 
The length of the tail varies somewhat. It usually enters twi(!e into the 
lenjith from its base to a point posterior to the eye, but .sometimes this 
point is anterior to the eye, and even rarely as far as the end of the 
muzzle. 

The head is a Hat oval, and the nuiz/.le is Hat, rather short, and some- 
what truncate in outline. The eye is situated anterior to the middle of 
the head and is quite small, itslont!,er diameter enteringr the interorbital

posteiior The tunj;ue does not reach the symphysis of the lower jaw, and is 

3d wilinn obtusely rounded in front. It is considerably free anteriorly. The in- 

1, and the ternal nostrils are an oblique slit on each side, which lies oblicjuely and 

posterior ojjposite to the interval between thevomeiine and pteryj^'oid teeth, 

oslte side Tiie i)remaxili.iiy teeth are in two straight divergent series, which unite 

at a rounded angle in front, which would be, if completed, a little less 

than a right angle. Each side usually contains eleven teeth, but there 

h are sometimes thiiteen and in one huge specimen (No. S'AH)) lllteen 

M teeth. The vomerine series is parallel within the premaxillaiy, forming, 

f like them, an obtuse angle anteriorly. There are twelve or thirteen 

teeth on each side, but sixteen in the large specimen (No. H.ICJO). Imme- 
diately posterior to the>e and at a short interval, the pterygoid series 
!7) commences. It is slightly convex outwards, and embraces usually six 

if tei'h, rarely live, and in llie large^Xo. .Si.(I())ten teeth. Thedentary boiK>, 

' supi)orts twelve or thirteen tec tli, which are dire(!ted obliquely inwards 

at a slight angle. The si)lonian)oae siipi)orts tour and sometiaies live 

" teeth, which form a short series posterior to those of the dentary l»<>ne, 

' whose base ascends gently backwards. In two specimens from (Jr.tss 

Iiiver, N. Y.(Xo. 7()o8) the teeth are rather fewer in number, viz: I'rc- 

maxillaries, eleven; vomeropalatines, eleven; jjterygoids, four. 

The limbs are well developed, but short and weak, as in salamanders 
generally. The two external lingers are subicpial in length, and siiorter 
than the two middle ones, which are also subeipu'' There are no dis- 
tinct palmar or su bdigital warts. The phalanges are, beginning on 
the inner side, l-.'S-IJ-L'. The toes are all unequal. The innei' is the 
shortest; then follow in order the fourth, the second, and the third. 
There are no solar or subdigital tubercles. The phalanges number 
l-L'-'J-L*. The limbs are of about enual length, and are ecpial to the 
width of the head just in front of the brancliia'. Tressed to the side, 
they are separated bv a distaiu!e equal to one length and a half of 
either of tlKin. 

The skill is entirely s.nooth, and has no longitudinal later.d fold. 
There are fourteen transverse folds — very rarely lifteen— which are not 
visible on the belly nor on the median dorsal region. A fold crosses 
the throat, connecting the branchial fissures; it is not very profound, 
and be(;omes obscure in specimens which have not been well preserved. 
I Wii-i.,iiirv:t. There are two branchial lissures only, there being none behind the pos 

terior branchial arch. The vent presents two short obtuse i)rocesses

rows of spots ofMark l)rowii, which are (piineuncially arranged, not very 
close together, in from four to eight or nine iricgiilar longitudinal rows. 
These are w:tiiting on the belly, but are continued on the tail. The in- 
ferior surfaces are dirty white, clouded with the color of the hack, but 
they are sometimes colored like the l)ack, iiielnding the dark spots. 
The soles and judms are yellowish. A dark brown band passes along

An entirely :Jack variety litis been sent me by J)r. ,T. (1. Carnier of 
Luckiiow, Ontario, which he hits obtained from the Maitlandiind laick-

habits of (wo iiidividtiiils of this species which he kept several moiidis

Tiic j-cncial form is mncli like that of the X muculatus, but the muz- 
is (IHlerent. I nsteail (tf bein^' depressed or even coucavc above, iunl 
ratiier wide, it is itinclicd at the si(b's,soas to be ratherelevated at the 
-nd,an(l tohave atnincate jirolile. 'J he head is wide in proportion to its 
enytii, tlic two measurements hein;;- about e(iual. The length of the 
taiNs the same as in S. nKicnlaliis, twice its length marking a point pos- 
terior to tluM'.ve. The limbs an' not quite so hing as in the N. maciilatiis, 
the spaee between them, when they are ai)pressed to the sides, oquabug 
twice the extent of the antciior leg, wliich is little longer than the pos- 
terior, in the specimens in the IMnseum the body is decidedly com- 
pressed, and (here is a distinct median doisal groove. These char- 
a(!ters aie less marked in the .V. muniUiliis. 

The upper li^) is more iieiidulous than in X maciiJatuN, or perhaps 
sueh an appearancto may bo ascribed to an elevation of thepremaxillary 
liorder, in accord with the more elevated muz/.le T!:e nostrils are 
a little closer together than in the larger species, the distah ,'e between 
them e(pialing half the interorbital spa(;e, nistead of two thirds. How- 
ever, in one of the four specimens this space measures two-thirds that 
l)etweeu the orbits. The brancthial processses are relatively considei ■ 
ably longer than in X inncuhitKs in all the specinuMis, and they aic 
more a(!umiuate in form. Tiieir length (tonsitlerably exceeds that of 
the muzzle in fr(»nt of the eye. In .V. maoulntuH they are usually 
shorter than this length ; in two or three specimens, however, they arc 
as long as in the X7>HHr/r(/H.s'. There are but two branirhial lissur.'s. 
The width of the head enters .").() times the length of the head and body 
together. 

The numbers of the teeth furnish distinctive characters foi' this 
sjiecies. They are: Premaxillaiies, 0-S; vomeropalatiues, 8-!> ; i)tery- 
goids, (J. Thus while the pterygoids are as numerous as in X maciddhis, 
the numbers of the other teeth are reduced. There are eleven <Ienta 
ries and three spleuials in the lower Jaw. The j)o>!terior uares aie a 
longitudinal slit opposite the space between the vomeropalatine teeth 
and the pterygoids. The tongue is short ami roumled,and extensively 
fr.ein front. The phalanges of the anterior foot are, L'-L'-I-'J. The 
metacarpals are connected by a slight web to their distal ends. The 
middle toes are equal, and the external and internal ones are e(pial. 
The posterior phalanges number 2-2-3 -L', and the digits are all unequal, 
and are very slightly webbed at the base. 

The skin is entirely smooth. The lateral tblds number fourteen, as i n .V. 
inneulalus. The muscidar part of the tail has a wide, free, dermal border 
above and lielow, The fonner is more slender than in most specimens 
of the .V. Dutciihitiis; but this charac^ter does not always hidd good. 
There are five cloacal papilla-, with the three anteri.u' iinelv fringed, 
as in N. Maciilatus.

vided. This is eoiiiiected witii a median hasal piecte, the i'lvat Uasi- 
branchial, i»y a sej-ineiit, i^enerally slendei', the hypobyal. Soinelinies 
tins piece docs not touch the cciatoliyal. Imoui the posterior lateral 
border of the basibraiu-hial there orii^'inatcs on each side a rod, the lirst, 
cerafobranclnal, which is continued after a Joint, as the first eidhran- 
chial. From a i)roccss which orij^inates between the bases of these, on 
flic siijicrior side of the Iiasibranchial, there oii,!4inates on each si<le of 
its postciior extremity another rod, shorter than (he first, the second 
ceiatoiiranchial. In some {(cncra (Ilyuobiida-) tlieie is attaciu'd to the 
(b'stal cxticmity of this lod a second one, continuous witli it, the secoiu! 
eiiibraiicliial. The second basibranchial is separated from tl: > iirst, 
and is situated far posterior to it, not far in advance of the corac(tid 
bones. It is better ossilied than iiutst of the rest of the liyoidx, and was 
called the thyroid bone by Ciivicr. Thatitis the distal extremity (d' 
the second basibranchial is shown by the fact that it is continuous with 
the first by a median rod in the larva-. (Plates l.l, l',">, I'O, ;}(», ,'{7.) 

The important differences disi)layed by the different forms of the

Salamandrida' and JMeurodelidie,* where it is united with the uli ar. . 
(Jenlr.ile always present. The carpaliii are live in Cryi)tobranchns and 
Aiiddystoma. and tlirei^ in Pletliodon and Dieniyctylus. In the tarsus 
then; are three bones in the lirst row, a lar^e tibnlare and intermedium, 
and ii sniiill tibiale. There is one centrale, as in the (!aii)us. The tarsa- 
liii nund)er live, except that there are four in tlie Salamandrida' and 
rieiirodelic'a', where the carjialia are on]/ three. Tiie internal or lirst 
tibiale is not distal, but lateral in Amblystonia and IMethodoii. It is 
<listal in Ciyptobranchus. (I'lati s -l."), 40). 

Jkrchpmciit. — The ejj-^s of rrodehi are laid in tli(! water nr on land. 
In the former (rase tlieyaie attached singly or in small numbers to the 
leaves of aijuatic plants. In the latter ca.se they are laid in little con- 
cavities beneath stones or hark. In Desmojiiiathus the albumen con- 
necting them dries into threads, which hold the eggs together. One of 
the parents lies by and watches them. In the Atnphiumoideat and tlie 
Apodal the female coils herself in a cinde over the eggs. 

In the growth of the larva- the branchia' and balancers are lirst devel- 
oiied, and afterwards the anterior limbs. The posterior limbs follow. 
Those s[)iracles or iManchial lissuies between the epibranchial bones 
which support the gills give passage for water from the ]»haryn.\. Then> 
are no internal gills such as are found in Anura. The branchial pro- 
♦•es.ses vary in lonii, but all terminate in IViiiges, in each of which is a 
va.scular loop. The varieties displayed by larva; of IJrodela as coni- 
pared with tho.se of genera with permanent branchiie are as follows:

,1, scribed s which have the extremity of tl;e limbs abnormably bifur- 
cate, but the iibiioriiiaiity is perhaiis in the direction of the evolution of 
diiiits. Dr. (i. I'.nnr believes that the third, fourth, and fifth di;;its have 
<;rown or sprouted successively in time from theexternal <listal allele of 
Mie ulna and fibula, while' the first and second are represented by the 
two orii;iiial branches. :| 

in the cranium a j;()od iiiaiiy important clian;;es occur before the bcnes 
iippcar.'l Anion};- the first of these is the division of the live simple 
tr.insverse branchial cartilaj^es ■'•, > t wo se<;iiieiits each, epibranehials 
and ceratobranchials, or, in the c.ise of the anterior arch, into cerato- 
liya' and hypohyal. Ho the maiidibiilar cartilaj^e immediately uiitciior 
to the ceratoliyal, divides into the superior (iiiadiatc, and the inferior 
iiiccUelian or mandibnlar. A snbseipient cliaii;j(! is the fusion of the 
(piiidrate cartiiafic at its superior end with the trnbeculiiin of its side-, 
and with the pterygopalatine arch with the inferior end. (.See IMate l>^,

tion as indi('atiii,n' ordinal separation from tlieCariliida' is not in aecord- 
aiice with our practice in similar cases in tlie l{ei>tilia, as in the oriler 
Laceitilia. 

1 have endeavored tosnstain the order Gymnophiona by the cliui'acter 
of the fusion of the nasal and premaxillary bones found in the majorit;* 
of tlie gonora.J lint Stannius§ shows that these bones are, distinct in 
Ichthyojilns. Huxley states (Anatomy of Vertcdtrato Animals, p. l").")) 
that in Jrlifhiiopliis nliidnosKs a distinct bone neaily eneindes the orbit. 
This he compares to the supra and postorbital i)ones found in the Stej^'o- 
cepliali. Uur in ("hthon;rpeton, Ca-iiilia, Dermophis, and other genera, 
this bone forms part of the maxillary, so that it is not (diaraeteristicof the 
family, and may not be homol(\iions with the bones wliieli occnjty the 
same position in Stcfioceidmli. Wieder.slieim calls it maxillary. 

With these fact in view I liave united || the Ca'ciT'da' with the L'rodela, 
a i»roposition which I fully believe to be sustained by the evidence. The 
Ca'cili'uhv is nfamiUj of I'rnihUt, cniiiiertnl with the typical forms throiiyli 
the Ampkiiimida'. 

ihwjrophical (listiHiution.''nni distribution of the families of the 
Urodela and their contents is as follows : None exist in the Australian 
realm and, exeeptiiij;- some Ca'ciliida', in the Kthioi»ian realm. In tlie 
Neotropical they are restricted to the Central American ami Mexican 
districts, with a few species in the northern Andes, and one reputed to 
be from the West Indian island, Santo Domingo. 

The Ca'ciliida' are more widely distributed, belonging especially to 
tropical regions.

The temperate rej-ions of the New World is, then, the home of the

The details of distribution are given under the family and generic 
heads. 

riij/loycuy — This order is probably of considerable antiquity, but no 
siteeies positively referable to it is known from any pretertiary forma- 
tion. In tertiary beds we have re])resentativesof ditferent types. The 
.utniis Chelotriton I'omel from the Miocene of Allier, France, has opis- 
llioiMcclous vertcbrie like most of the e.\istin{>' sjiecies of Euro])e, and 
has in addition an expansion of the neural spine of each vertebra, to 
which tlie epideiniis was closely adherent, yiviiiya row of roujih plates 
down the middle line of the back. Jleliarchon and I'olysemia of Von 
.Meyer are known fronj specimens from the Miocene beds of (Jermany. 
They have apparently the cartilaginous carpus and tarsus of the Amer- 
ican genera. The .Miocene of Switzerland has liirnished the renuiins of 
a species, i»robably of Cryptobranchida', which has been referred to the 
genus Aiidrias by Tschiidi. It is very nnu^h like Cryptobranchus. 

In older foimations we have in the North Aniericau Laramie the 
genus Scauherpeton Cope, which may well belong to the Urodela, but 
the skull is unknown. In the Wealden of Belgium the genus Ilyheoba- 
tnichus Dollo may belong to this order, but the skull is not yet well 
kuowu.

Ill tliis ;;('iiiis the voinc riiie leelh form a re<;iilarly arched series, eon- 
«'eiilric with the maxillary seiies. Tliir lon};ue is but little free, and 
that only round the edges. The coliiMiella of Ihe stapes is eartilaf-inous, 
and is connected by a close articular contact with the quadrate carti- 
l.i.neand with the under sideof the siiiiamosal bone. The ceratohyal 
is connected by a ligament with the posterior sideof the quadrate, with 
the intervention of an oval cartilage, which has the position of the sty- 
lohyal bone of fishes. The posterior extremity of the ceratohyal is not 
in(Mirved, and is free from the skull. (Plate IS, lig. 3.) 

Tiie hyoid apparatus is«piit(^ characteristic. They have been already 
desciibedso far as they <lellno the suborder Trematodera. They re 
senible the Pseudosauria in having twoceratobrauchials, but differ from 
them and resemble the Amphiumoidea in having no first epibranchial. 
This element may, howevei', be continent with the first ceratobranchial, 
but no suture appears in very young specimens. The ceratohyals ar«^ 
divided transversely and the hypohyals are large. They are not m 
contact with each other or with the first basibranchial, as in other or- 
ders and suborders, but are separated by u pair of transverse elements, 
which are i)robably true basihyals. The first basibranchial appears to 
lie interrupted at its middle, the anterior part remaining attached to 
the basihyals. No second basibranchial. 

A broad cartilaginous plate rises from the basibranchial and supports 
the tongue. It resembles a good deal the otoglossal cartilage of the 
Amblystomida>, with which it is prolyably homologous.* Tlie second,

the middle line below. The i»ubic region is represented by a lai'j>e sim 
l»le eartilajje, which is pr.xluced into a style on the middle line anti'ri-

Its position dilfcrs from that seen in .1 mphhnna menus and XcctKnis in its 
beiuj;iit the end of the row, and not external to it. The roof of the mouth 
is everywhere Hat. The ton;;ue is wide and is considerably free in Ironl, 
the free border iiarrowinj,' laterally and jjosteriorly. It nearly fills the 
floor of the mouth, leaving;' but a narrow space between it and the man- 
dibular arc. Its surface is thrown into numerous elevated folds, which 
are thin, and generally anteroposterior in direction. They inter(!oni- 
municate by lesser (»bli(iue folds, which with other delicate ridges form 
anet \vo>k between the principal ones. In old specimens or badlypre- 
serv'.i ones the plica' may be tlattcned or lowered. 

The legs are (piite short ; when pressed to the side they are separated 
Ity a space equal to l.'J.j the length of the anterior limb. The lingers 
are short and rather free, and the external one is considerably shortej' 
than the internal one. The others are subsequal. An extensive fold 
of the skin extends from the axilla to near the extremity of the external 
finger, forming the posterior expanded border of the limb. It is mo>t 
prominent at the h)wer part of the ui)i>cr arm. The posterior t(»es aie 
rather short, ami are free from web as to the phalanges. The first is 
the shortest, and the second a little exceeds the fifth. The third ami 
fourth are subetjual, and, with the fifth, are somewhat depressed. Ibis 
appearance is produced by adeimal wing on the external border, which 
increases in width from the third to the fifth, becoming veiy wide on 
the latter. It continues from the fifih toe on the hinder border of the 
leg to the base of the thigh, (iorrespouding with the similar fold on the 
fore leg. The ei>idermis is not hardened into ungues in this species. 

The skin is perfectly smooth, but is thrown into a longitudinal iindir 
lating fold on the sides betwten the fore and hind legs. Th s fold i^ 
obsolete in some specimens, apparently on account of the distension of 
the luHly with food or eggs. There are a shallow median dorsal groov.' 
and lourteen costal grooves. The latter are not distinct on the back or 
belly, and are best seen on tlu- sides (.f the latter. The tail has a fre.' 
dermal border oi: its superior edge, but none on the inferior edge, thus

tail divides it into ii snperior and infeiior portion, and a lateral wedge- 
shaped mass, covered with longitndinallyfoldetl skin, intervenes between 
the two for abont one third the length of the member. J)ermal mncons

There is .some variation in specimens in the relative distance of one 
nostril from the other and from the eye. In some specimens these dis- 
tances are identic^il ; in others the former is somewliat less than the 
latter, and the same measurement, usually one half the w idth between 
the eyes, may enter it L'.'_'."i times. 

A local variety is .seen in three .specimens (No, 7()(>r») from Abbeville. 
S. C. These aie a li.yht brown, much resembling the G. /'iisviis, but are 
spotted with a darker brown. The double papilhe are not vi.sililc on 
the superior surface of the head, and are faintly marked on the inferior 
aspect. The rows of pores are, however, as in C. (iIletilicniciiKis, as are 
the tongue and internal nares. The digits are all iikhc .slender, and the 
dirmal ala 011 the extei iial toe and that of the elbow are niiieli reduced. 

IJesides the generic character, the following dirfereiices may be ob- 
served on comitarison of this .siiecies with the Mcnidiihiitfaclnis ina.rimus- 
of Asia. In the latti r the tongue is not free, luit is sessile, and with- 
out plica'; head with rows ofoltu.se tubercles; sidcy and limbs williont 
dermal folds.

ita;^ive.s with some siH'i:iiii>Mis fi'^ai Abbeville, S, C. (No. 7()0.">), already 
refiM ivd to. I do not attacii niaeh importance to the abstMiee of tiie lat- 
eral folds, as distension of the alidomen from any oMiise would be apt to 
canse it to disappear. These two characters, however, with the brown 
color, supplement the three important ones f-iven in the dia,unosis, and 
c(»iifiim the propriety of recoj^iiizinj,' the species. Nevertheles-^. tiu' ob- 
servaion of other specimens prescntin;;' the same features will be neces- 
sary befoie the siiecies can be rejiarded as fully estalilislied. 

Tiieheiid hasthewi.lc, (1 ir form of t lie other species, with the very slim- 
and broadly rounded mu/zle, but these characters are e\ ij>j;erated. 
Thus the Icnjith from the end of the muzzle to the lines c.oiinecMii.j; the 
anj^lcs orcauthusof the mouth entt'rs the greatest width of the head 
loar times and a fraction ; while in the ('. ((Ilriihciiini.sis it is one-half tlir 
liwuo. measurement of the width of the lu>ad, or even a little Ioii;^rr. 
The sliortness of the <;ape as compared with its width is also indicated 
by the fact that the canthus oris is below a j)oint anterior to the anterinr 
canthusof the eye in the C./iihciih, while in the (\ (tllnilicnifiisis i\w nu<^\v 
is below the posterior canthusof the latt /r. The eye is smaller than is 
usual iu the C aUc(jhcntci}.sis, its lonj^ diameter entei'inj; the iidcroeulai' 
Bpace a little over seven tiniL's; while in the more abundant species it en 
ters five times to nearly six tiiru's. The extremity of the maxillary series 
of teeth corresponds with the canthus of the month. TIm^ vonu-rincs 
have only half us much length. The int.rnal nostril is a slit, nearly 
closed, in line with the series of vomerine teeth at tiieir extremity. I 
have not found it closed in tiiis way in any specimens of tlu^ ('. nlhulir- 
nicii.sis. The characteristics of the toii,i;ue form one of tlu^ slroiij^cst 
character* of this species, Its superior surface is covered with lai',n-e 
truncate papilhe, so closely placed us to be everywliero in cont;icl. 
Tliey are only distinguished, as in the human tongue, by Ixuiding the 
surface. Xotliing like this is known in the other si)ecies. Here tlu^ 
surface of the t')ngue is murked with longitudinal plica', separated by 
considerable intervals, .wliich are tluunselves subdivided by smaller ami 
lower plica', the general result being an appearance somethiMglike tripe. 
The width between the external nares is half of that between the orbits 
or the posterior nares. 

Thecrtptsof the skin of the superior surfaces are coarser than in 
the r. aUcghcnicnsis, especially on the posterior half of the head. The 
anteri(U- half of the latter is smooth. X.. trace of the double papilla' 
is to be found on t'u', sii'iir.or surfaces, but they exi^t iu tlie arched 
series rouiul the lower jaw below the lip, as in the other specie's, bnt 
with thisdiflVrence: the papilhe one above the other ai'c net round, 
but short longitmlinal keels, so as to be parallel to each other.

in the order of length as follows, beginnin";- witli the short inner, 1, 5,

three external are ribbed from the tips ; the notch between the third 
and fourth reachinj,' the end of the lirst phalange, but between the 
fourth and filth extending from tip to tip, with a very slight notch 
(easily enlarged by tearing) ; the legs are about as long as in C. allajhc-

distance equal to one and a (luarter times the length of the hinder leg. 
This measurenuMit must betaken with some allowance, as the S[)ecimen 
has been coiled in strong alcohol, and its true form is not easily restored. 
It is impossible to distinguish the true lateral folds. An estimate 
nuikes them equal those of the other si)eeies, tburteen. The tail has 
the usual form. Its superior outline rises from the base, and is convex, 
and consists partly of a thin dermal border. Tlu^ extremity is thin, as 
is also the distal fourth of the inferior edge.

This family is of particular interest among the Urodela, us furnishing 
«'onnecting forms between the ordinary types of the order and those 
larger species which we suppose t(> be more characteristic of former 
periods of the earth's history. It also furnishes us with transitional 
coiutitions of characters which have been regarded as indicating very 
diverse origin and nature. The species are mostly of large size, and 
are probably confined to Xorth America; perhaps a species exists iu 
Farther India.

that is, one lias not Ix'cii assnined after iiossession of the other, nor is

(hiecd lamina' of tin' Salamaudrida-. and the absence of deiitij?eious 
plates on the paras]ilieiini(l in the IMetlKMlontida' is a character of the

The biconcave vertebra- constitute a ix-rsistence of a larval feature. 

The preseuce of ptery.i;oids has the same siynilicancc with refereuce 
toother families. 

Theossilieatiou of the carpus and tarsus are characters in which this 
•iKiiip develo])s beyond the larval condition which is permanent in the 
family riethodontiihe. 

Thus of eight characters fAo are iiKuphic and six developmental; 
of the six, two are of advanced develoi»inent and four of reitrcssed 
development, as compared with other fanulies. 

The writer characterized this family nearly as above in the .lourual of 
the lMiiladelj)hia Academy, lS(i(!, 105. J)r. Ilallowell proposed it in the 
same worii, 1858, 337, but on iiisulllcient characters. iMany of the char- 
acters of the i)riiicii)al {^enus Amblystoma had been already pointed 
out by Professor ilaird. The .yenera imduded by Ilallowell were Am- 
blystoma, Xijiltonura Tsch , and Onychodactylus Tschudi. Clray had 
previously end)raced the same genera with llctvrotriton dray, in liis 
first section of the IMethodontida', which corresponds with this family.

Cope, and 3Ie,ualol)atrachus Tschudi. in the above citetl essay of 1S(»<»

The wivestijiation of the subject which I j^'ave in my nujuograph of this

Megalobatrachus, the great salamaiuler of Japan, I have determined 
to pertain to the Cryptobranchida'. The genus Camamtaxh, as will 
appear further on, was established on a larval character, permanent 
in some individuals it is true, but not permanent in any si)ecies. On 
the other hand, there is some probability that onci or both of the species

Tli»' Stroud iMsiliriiiicliiiil olcimMil is tiaiisvcisi-, ^ciu'rall.v aii;;iilii(nl 
loiuiinls, and is wdl ossilit-d. Tlicotlu-r parts of llic li.yoid appaialiis 
lliat are ossiliod are tlie proximal portion of tlie eeiatoliyal, tlie ante- 
rior [Kirtof the first basibrancliial, and the free extremity of the linst 

t'piivriinclMal. 

Till' htrva' are eliaracterized hy the Ion;;, slender processes of the 
three braiieliial lamina', which hrar tlie vasenlar limbria', rather than 
tlie lamina' themselves, as in Cli(»ndn)tns. The internal nostrils are eon- 
lined between the maxillary series ol teeth and the palatine arch, wlii(di 
is concentrie with the former and near to it, and iseontinned backwards 
on each side in line with a similar series on the pterypiid bones. A 
relation of nostrils to palatine teeth similar to the above is permanent 
in Ampliinma, and one intermediate between it and tlu' adult condition 
of Amblystoina' of ;;roiips iii and iv ehaiaeti'i izes Cryptobianclins. 

The tail and back have a tree dermal mai',uin, but there is none on 
the lindts or dii,'its. The tail is short and deep. 

The following' are some of the most readily observed characters which 
are assumed by the And>lystoma' at the pi'riod of their transformation : 
(1) The series of teeth on the splenial bone is shed ; (-) the caii)us and 
tarsusossify; (."5) the tail narrows and leiijrthens; (4) the branchia' dis- 
appear; (5) thetonyue enlarf;es and covers the lloor of the mouth; (0) 
the pteryj^oimlatine series (»f teeth becomes more nearly transverse; 
(7) brightly colored pij;;ment is deposited in the chromat(>i)hora' of tlie 
derm. These changes are stated in the order of their occurrence. IJut 
in some of the protean species this order is not exactly observed in all 
individuals, and in conse(|ueiice of the assumption of one or the other 
character of maturity in advance of another the number of s[>ecies has 
been supposed to be greater than it is. The same irregulari!.\ in the 
successional appearance of structures is well known in the earlier pe- 
riods of embiyonic lite, as stated by Von I'.aer in the sdudia of his lOnt 
wickelungs geschichite. In the chick, different poitions of the vertebra! 
axis and the abdominal plates may or may not appear in the usual 
Older of succession. 

In Amblystoma the aiiproxiiiiation of the period of reproduction to 
that of transformation varies with the species, and it is evident that 
the closer this api)roximatioii, under tlie above i»rmciiile of variation, 
the more protean will the species be. As we know from the exi>eri 
meiits of Hogg, J)umeril, and others that inetamori>hosis i.s greatly has- 
tened or delayed by the conditions of temperature and light, what would 
mit be the elVect on individuals of such a protean si)ecies of a change 
of toiiographical situation, such as the elevation or (lei»ression of the 
land :' And I have no hesitation in saying that if the peculiarities of 
series of individuals of .1. t'Kjr'nuini, in the respects above enumerated, 
were permanent, they would characterize those series as species as 
completely as any that zoiiiogists are accustomed to recognize. For 
the evidences on this head, see the discussion of this species below.

Other experiments, whicli will not be (pioted now, aic ('(pially (ton- 
elusive as tot lie effects of iinlit and heat on their process. The dis- 
tinction between iiiatiirity, or adult aj;v, and complete devel()pinent 
must be borne in mind. The former (Mtiiditioii is attaiiu'd when the ova 
an; fitted for imprej^iiation and the spermatozodids are capable of accom- 
plishing; that result. Development may or may not advance much 
beyond this perioil. .Vs one or more periolsin the life of every species 
is characterized by a i^reater rapidity of develoinnent (or metaiiKM'pho- 
sis) than the remainder, so in proportion to the approximation of such 
a period to tlm ei>ocli of maturity or reproduction is the olfspriny liable 
to variation.

tlu! number to sixteen. In my monograph of this genus, ]»ublished in 
1S(J7, the si)ecie8 described numbered eighteen, six new ones being 
added. Dr. IJoulenger, in the Catalogiu- of the IJritish Museum, second 
edition, published in 18815, gave the number as .seventeen, including a 
Siamese species. In the present wmk thirteen species are admitted, one 
of which is the Siamese species A. iicfsiiiiilis, after the subtraction of 
nine species placed in the genera ('huniirntus and LhujiKvltipsUH. For 
the stmly of this genus the collection of the Smithsonian Institution is 
une(pialed. Probably the second best collection existing, that of the 
Academy of Xatural S(Meiices of I'liiladelpnia, has al.so furnished its 
numerous types, and several species mostly described by the late Dr. 
JMnvard Llallowell.

Siiortest, stoutest, and most cluiiisilv furiiu'd of all the tenestiial 
Ambli/fifiiiiialu. Character of skin as to },'laiids pits, etc., much as in 
A. punvtiitiim and (iiHUum. A row of lar^'e |»ores on the head, interior 
to the eye and nostrils, extending;' anterior to the; latter. This i>asses 
behind and beneath the eye, reachinjjf forward nearly to the nostril: a 
patch on the cheeks above the lateral j^roove and another below it, 
probably oxtendinj;' lorwai'd aloiifi; the lower Jaw. 

The head is very broad, and laifj^e, and is wider than the body anterior 
to the constriction at the neck. Its width is about eipial to the distance 
from snout to gular fold (thus wider than Ion;;;, and is contained about 
;3.] times to the j^'roin. The eyes are sujierior and ratln^r small, separated 
anteriorly by nearly tlii'ee len;4ths of the orltit; about oik^ orbit froi!i 
the nostrils, which are separated about 1.] orbits. The mu/zle is rather 
an^'ular. The ui»per Jaw is visible beyond the lower when viewed from 
below. 

The body is short, siiurtt, and depre.s.sed. There are 10 costal i^ioov «'s 
on the side. 

The tail is contained about 1.] times in the rest of the animal. It is 
much as in .1. oixtcum, but hi^ij^her, thou;-!! witiiout a crest. 

The dij-its are rather Iou{,' and slender, .scarcely dilVerent from those 
of A. opftcum. 

The i)alatine teeth are in a transver.se series of three sections. The 
middle .section is not interriii»(ed alon;;' the median line. In the type 
it is slightly concave anteriorly, .scarcely ivachiiijn to the inner line of 
the inner n arcs, and behind the rani^c of the lateral sections, which 
beyin a little interior to the outer line of the nostrils. The middle and 
lateral sections are separated by the width of the inner nostril. In 
another specimen the middle patch is nearly strai,i,Mit ; in another, com 
po.sed of two ares concave anteriorly. 

The tongue is thick, fleshy, and adherent, though the edges are free 
at the sides; le.sssoat the tip. Its width is not niT-lhun half that of 
the head. The papillo.se i»ortion is separated itosteriorly by the exten-

The papillose ridges are longitudinal and nearly parallel. 

In alcohol this spe(;ies is a light brown above, paler beneath, irregu- 
larly spriidvled, blotched, and marbled with silvery or jduinbeous gray, 
oC a li(;hon-like character. Specinu'ns when alive show the ground color 
to be a dark brownish or liver black, more livid on the sides, and per-

of larger size on the back. The ;ii)per part of the tail is of a purer 
brown than elsewhere, and is bordered by a series of obscure blackish 
spots ; seen also near the lower maigin. A few similar dusky s])ots ap-

out nu'tallic luster. 

A. series of speciiiuMis from Prairie Mer Rouge, Louisiana, is quite 
similar. ^Souu^ of them appear to have just completed the change from

I found this species abundant in the high valley in southwestern 
Noitli Carolina in whi(^h the I'reiich I'road Ixiver takes its origin from 
mountain streams. Thence it extends through the .southern Atlantic and 
(lulf States to ami including liouisiaiia, west of which it lias not yet been 
foiiiKl. It is not aquatic, but lives in damp i)laces below logs and stones.

connected with the ylands, whieii lire seen everyw hei'e on the Wody and 
tail, except, perhaps, on the lower part of sides, belly, and beneath the 
liead ; on the tail, however, they are most developed on the npper hall". 
There are no rejjiilar patches of more conspieiions pores on the liead 
and parotoids, as seen in A. puuctatiim. 

Head rather broad, depressed, its {greatest width about •,' the length 
from snout to jjnlar fold, and about f, the distance to insertion of hind 
lefjs. Axial leiifjth of mouth half that to ji'ular fold, which is iiiter- 
rnpted on the nape; a constriction behind the aiif-lc of the month, with 
a lateral {jroove (or ridj^e) connecting;' the two as in ^1. piiiirtdfiiin. Ins- 
tance from snout to {jnlar fold not (piite 3A times in that to insertion of 
himl lefj. The eyes are moderate; the pupil (arcular. The jicneral r»'- 
lation much as in .1. piinrtdtiim. 

r.ody nearly cylindrical, but decidedly depressed. No indication of 
a dor.sal furrow. Eleven well marked costal furrow.s inciudiii;: flic in- 
guinal. There are about four pelvic; furrow.s; those on the ba.se of the 
tail aredistiiHit anteriorly, but "rradually become fainter. 

The tail is oval or subellii»tical in cross .section, thou<;h williont any 
indication of a keel. It is nearly cylindrical at ba.se, lhou;;li sb<;|itly 
(ioi.ipressed, becoinitifj more and more so to the pointed tip. It is 
thi<!ker above than below, and measured from beliiixl llie anus is con 
tained U times in rest of the leiif;th. The lateral {rroove on the tail is 
less distinct than in A. punctatiiiH. 

Tjic digits are linear, depre.s.sed, fuit without any indication of web 
or marfrin. The third or longest linger is one-third the distance from 
its tip to the elbow ((contained three times). The lateral ones are ipiite 
short. The fourth toe is longest, and contained L'^ times in the distance 
from its tip to the knee; the .{, ."., L', I are suci-e.ssively shorter, or the 
tilth and .second are about eipial. The distance between the outstretched 
toes is contained about once and two-sevenths in the length from .snout 
to behind anus. 

The tongue is thick and lleshy, as in .1. punclahim. though larger in 
])roportion, and tilling the mouth more. TIm' teeth aivinoiie transverse

The principal dill'ereiice in I'orm and strnctnre between this species 
and A. pumfatum aresec^i in the abseiuie of any dorsal furrow, and a less 
proiniiien(u> of that on the side of the tail. The limbs are more feeble, 
the head narrower, the tail shorter, et(t.

This species is found in drier jiroiiiid than is conociiial to most sal 
amanders. I have taki'ii it in tiu' sandy ri'^ions of New Jersey and 
Delaware.

tlie tail, or tli(!S(! tluTc is a piitcli of laif^er <)lu^s on the i>aiot<)i«l rcjiioii, 
and aiiotiier on the top of the head inside of tlie orbits and extendirij;' 
antei'ioily in a straijiht line towards thc^ nostrils and passing;' bactkwards 
seMiiciniuhirly behind tlie e.ve. A doable row around the edjje of the 
lower Jaw ; a jiaii' on ea(;h outer (postal space alonu' tlie side of the body, 
and a row on each side of the top of the tail ; the latter indicated {jen- 
erally by a whitish dot. 

Head broad ; depressed ; width nearly (Mpial to distance from snout to 
K'nlar fold, and nearly one Ibuith the distance to insertion of hind le^s. 
licn^th of mouth alonj^' axis of body half distance from snout to liular 
fold, which is nearly continuous a<'ross the nape. There is a constiic'tion 
behind the ar-yle of the Jaws, interrupted above and below, and a fur- 
row eonnectinj;" the two alonji' the jjaiotoid re.i^ion and extended in a 
lateral line to the oibit. Distance troni snout to jiular fold <'outained .'U 
times in distance to insertion of hind legs (four tinu's in another speca- 
nien). 

Theeyes are moderately laru'e; the longlh of the orbit contained t.l times 
in distan(!e from snout to <iulai' fold; about once in distance from the nos- 
trils, and about on(H' in the distance between the two nostrils : nearly 
twi<!C in distance between the anterior extremities ol'the orbits. 

Uody nearly cyliudri(!al, perhaps slightly depressed, and swollen a 
little in the middle; on each side are t'leveu costal <rro.)ves, iiuiludinc: in-, 
guinal and axillary ones ; all strongly marked an<l nearly continuous 
above and below; the axillary is, however, usually (juite inconspicuous; 
four more of these furrows to behind the anus, wlnu'c the last is (ronlln- 
ent with the tirst caudal furrow; these become less and less distin(;t to 
near the middle of the tail. There is a slight groove down the middle 
of the back. 

The tail is oval in se(!tion, the larger end of the oval below ; becMnn- 
ing more and more comi»resscd to the tip, without indication of any 
ridge. There is a lat«Mal indentation along the whole length. wlii(Oi is 
about e.jual to the distan(!e from the base to the sn()ut. In alcoholic 
specamens the tail is bent or curved, sometimes upwards, sometimes 
down, sometimes lateially. 

The digits are nearly (cylindrical, or slightly depressed, without web 
or nnirgin. Th(> third or longest linger is contaiiu'il al>out 2\ tinu's in 
the distancic to the elbow. The second linger reaches to the last artic- 
ulaticMi ; the fourth to the |)enultimate. 

The fourth toe is longest, (contained L*;\ times in the (listan(!e to the 
knetc; the third, second, lifth, and first succ(vssively shorter. The dis- 
tance between the outstretciu'd hind toes is rather more than L', the 
length to behind anus. 

The tongue is thi(!k, lleshy, and attached, although free at the (^Iges 
except behind; it is about two thirds the width of the upper jaw, tu'arly 
orbicular, though the outline of the papillose i)oiliou is a little emar- 
ginate behind. Italmost seems as if the tongue wei-e capalile of closing 
round an obi(M;t in its c(>ntt>r. as in th(> hollow of the li;ind.

In the preceding paragraph I have described a specimen from Abbe- 
ville, S. C, as a lo(!idity nearest to that whence the original of liinna-iis's 
des(!ri|)tion was obtained. An exaiuinatiou of a large sei'ies of speci- 
mens from different localities shows certain differences, whicii, however, 
arc not of a character to indiiNite specific separation. 

The external appearaiKte of the skin varies consideral)ly with llie 
.strength of the alcohol used far lueservation, and probably with the 
season when capturt'd. The animal, when alive, is perfectly smooth and 
lustrous, and readily exudes a large (piaiitify of a white milky Juice fVoin 
the upper half of head, body, and tail, or from the dark-cohu'ed portion. 
This is due to the presence of glands closely implanted in the skin, the 
])ores of whicli are sometiiiu>s (piite iiieonspi(Mious ; sometimes very dis- 
tinct. On the tail they are much largest and di'cpest, and the lateral 
groove marks their inferior boundary, being there implanted verti(!ally. 
When these pores are very full of their milky juice and the alcohol is 
very sfrtuig the contraction of the skin betwciui the mouths of Wwsv, 
pores gives imue or less the appearance of roundtMl, thick-set granules, 
of rather large size. This also gives rise to an ai)parent deiuession (tf 
the digits, the skin forming quite a margin 

The proportions of the body vary slightly. The tail is generally not

the middle point oftlic axis. Yonnjier specimens appear to liave sliorter 
tails. 

Tliei'c is considerate diviMsity in tiic cniv*', of the tiansverse series 
of palatine teeth. In ncnirly all more northern specimens the central 
row is formed of two arcs, concave anteriorly, more or less continuous 
with the lateral, which are anterior and convex anteriorly. The two 
central arcs arc continuous at their inner ends, forminj;' an inveited 
an^ie on the axial line. Sometimc^s, however, as in mosr of the 
sptuMmens from Prairie Mer lioujje, tins central anslc is wantiu}?, and 
there is only a sinjjle arc or curve, (loncave anteriorly. In tlui type 
spiMMmi'u described this central row of tiietli is nearly or (piite strai};ht 
(which is quite apt to ho the case in v(M'y large ones), while in one 
specimen of No. U'tSi it is convex anteri(>rly. The transverse extent 
of this middle line of teeth varies. Sometimes there is «;(iite an interval 
hetwi'cn it and the lateral, while in 31).'>(>, from New Yo k, they are con- 
tinuous without ai>pre('ial>le interruption. 

There are no very great variations in the pattern of coloration. (Gen- 
erally the outer surface of the limbs is colored like the back, in which 
cas(^ there are one or mon*, large, rounded light spots. The under parts 
aie generally dark bluish; the sprinkling of small whito specks on the 
sides and beneath varies considerably in prominence. Tlie large dorsal 
spots are always nearly circular, and vary in number, generally only one 
series «)n ea(th sidt*. 

In living specimens from Carlish', Pa., the iris is dark brown, without 
metallic color, scarcely distinguishable from the jiupil. The color of 
the animal above is adeep anthracite black; beneath, dull livid. On 
ea(!h side the <lorsal line is a series of large, nearly circular, gamboge- 
yellow spots, somewhat symmetrically disposed. These vary from !(► to 
L'(» from head to tail, and sometimes are laiger than the eye ; usually 
about its size. On tiie sides and beneath are sparingly scattered small 
bluish-white si)e(^ks. The spots, both yellow and bluish-white, are some- 
times found on the legs. 

In youngei' individuals tiie yellow sfiots are brighter and the black 
ground deeper. — 8. F. I>. 

Professor IJaird (I(M>nographic Etn-ycloiia'dia, 1S,51,) thus describes 
the reproduction of this spcM'ies : 

' ICarly in April, or towards the (Mid of Miirch, large masses of gelati- 
nous matter may be observed in ditches, jiools of water, or mountain 
streamlets, which on closer inspection will be found to consist of a num- 
ber of hollow spheres, about a quarter of an inch in diameter,embedded 
in or combined together l>y a perfectly transparent .jelly. Within each 
sphere is a, dark obje(!t, a sph iindal yolk, which in the course of some 
days becomes (considerably elongated and exhibits signs of animation. 
Omitting, as unsiiited to our pages at present, any ac(^ount of the em- 
bryonic development of tin^ animal, we resume its history at the time 
when its struggles have freed it from the shell of the sphere in which it

The lu';i(l is lar^'f, somewhat wider than tlie body, and Ualdiiu'd; the 
body short, and tiio tail h)ii^ and coiiipitissed. Tiiesi^in is tor tiic most 
part smooth, bnt rvcrywiit'iv, as seen nnch-r a Kmis, is pitted with the 
openin};s of the entaneous follicles. Of tliese, there area fewenlargeil 
ones in a band snrronndin;;: tiie orbit and extending; forward to tlu; 
iKKstril. Others are fonnd alK)ve the angle of the Jaw, and a few still 
lariier ones on the posterior border of the i arotoid n'gion. The promi- 
nent keel and the whole tip of the tail aie so riehly provided with 
eidarjjed pores as to present a Ki'iiniilated appearan(;e. 

The width of the head is somewhat greater than that of the body. It 
is possible that the breadth and llatness of the head havi^ been exag- 
gcu'ated somewhat l>y the injnries that it has recu-ived; but this can Ix' 
trne only to a very slight (vxtent. The breadth is abont the same at the 
angle of the Jaw and the corner of the month. From the former point 
the head tapers backward, the ontline being coiutave to its posteiior 
border, where it is snddenly constricted into the necik. From the cor- 
ners of the month tlie head tapers forward to nearly opi>osite the nostrils, 
beyond which it is rapidly rounded to form the snont. The width of 
the head is a little less than the distance from the snout to the gnlar 
fold, and is (contained in tlu' distanei^ from the snont to the groin .5.0 
times. Tlie distance to the gnlar fold iscontained in the distance to the 
groin 3.1i tinu's. The depth of the head, on a line Joining the angles 
of the Jaws, is a little less than one half its width. The gnlar fold does 
not overlap, as it tloes in some s[n'cies. It may have done so in lile, 
bnt manipnialion of the skin fails to restore an ()verlai)ping fold. Tlu; 
npperjaw projects beyond the lower. Fyes of moderate size. Externiil 
naies small; their distance apart somewhat less than the width of the 
interorbital space. 

The tongne is not notably dill'erent from that of .1. fitfriiium. The 
teeth are arranged in four series, which together form an inverteil V? 
the angle of which is very obtnse. The limbs of the V? 'i'"* •'^^•^"' ^^''•''' tlie 
nnaided eye, ai>pear nearly straight, and are .seen to extend beyond the 
internal nares along their external lissnre. Examination with a lens 
pnnes that the inner seriesare each slightly /-^/shaped, ami .so disposed 
as to make the angle of the V r«)iinded oil". Th(M>nter series on each side 
is nearly as long as the corresponding inner series ; is plaiidy .separated 
from it, and nearly straight or slightly concave on the pt)sterior side. 
Inner nares more; distant than the exterinil. The body is sonn;what 
dei>re.s,sed, but has not the swollen ai)pearan(!e |)resented by A.opacnm. 
The distance from tlM^snontto the axilla isjnstetinal to that from the 
axilla to th(> groin. There are eleven well-marked costal grooves. Then^ 
is a median fnrr<»w, not deep bnt distinct, beginning on the occipnt 
ami riinnwigalitii ^ (hv^ b.ick, di'i-pening o.i the sacral ri'gion, and emling 
over the middle of the vent, at the comnn'ncement of the caudal crest.

Tile tail is e(|nal in !en;^tli to llic distance from tlie snout to tlio be- 
^iuniu;^ of the vent. It is niucli compressed and rather liinli. ItluiHU 
well ileveloped keel or crest, which l)e;jfins luinitMlialeiy over the chmc-ii 
and extends to the tii» of the tail. The keel is sharp above, and is 
bounded below on each side liy a shallow <;ro(»ve. inferiorly the tail 
is broadly rounded for its anterior third or nn)re, and is traversed by a 
median longitudinal {rroove. The remaimler (»f its lower Ixuder is 
compressetl t(» a sharp ed^^'. A tiansveise section of the tail, taken Just 
behind the cloaca, would form approximately an isosceles triangle whose 
base would be about one half ils heij^hf. One-third of the distance back 
toward the tip the heijjfhtof the tail is three times its thickness. 

The limbs aic well developed. The posterior aic a little loiij,'er, some- 
what stouter, and the foot broader than the sanu^ limbs of a specimen 
of A, tiiiriuinii that measures the same distance from the snout to the 
end of the vent. They are also tally as lon^j as the same lindis of ji 
specimen of A. punctdtinn that measures from snout to the end of the 
vent tliieefourths of an inch moic than the specimen 1 am describin<;.

while they are not so slender as those of a specimen of .1. itiunlnliiin

Tlic above table of t'oniparative measuronients sliows that -1. hicnior 
h.is. in comparison witli .4. vopeannm, a h)n{j('r and still broader head; 
ii! spite of tliis. a distance from (lie axilla to the {iroiii ^Teater than that 
Irom the .snon* to the axilla, a nuich shorter pelvic rejjion, and shorter 
fore and hind limbs. 

Found at Ir\ inyton, near Indianapolis, April 7, 1885, by Mr. George 
II. Clarke. 

The siiecimon on which the description is based was found dead an<l 
somewjiiit mutilated. The injury that it has snllcreil does not, how- 
ever, ill any way ob.sciire the eiiaiacters of the speci»'s, ainonntinj;-. as

The above description is taken from the type from Heesley's Point,

( Miirj) from the same locality, in the National .Museum, dilVers in two 
important particulars: The palatine teeth iire not brush-like, but are 
conliiH'd to the crest of tii<' lidge, and the tail is a little longer than the 
head and body. The niuz/le is ratlu-r longer and tiie mucous pores 
more numei'ous. It may belong to another species, as the .1. fifirinum, 
which it much resendtles, l)ut its eleven costal folds are a notable pecu- 
liaiily. Tlic A. hitolor, though nearest the .1. /(V/r/MKMj, appears dis- 
tinct, after a <'aieful scrutiny of several individuals.

THE IJATUACHIA OF NUHTII AMKRICA. 



69 



^1> 



(ieiKMul form very thick ami iiiassivc, altliougli tlic lii'ad is propor. 
tioiially small in mature specimens; not as broad as the hody. The 
skin appears cpiite smooth when fresh, esjtecially when covered with 
its epidermis. On removing this, however, the skin is seen every where 
closely covered with shallow pits, interspersed with yranuh like pro- 
jections of (he ylands. There is an indistinct line of i»ores on each side 
of the head interior to the eye, but they can be scarcely traced else- 
where. 

The parotoid rejjion is innch swollen, w ider than the skull, and about 
e(|ual to the <listance from snout to j;ular fold. The width of tin- Jaws 
is contained about four and one-half times in the distance to the j;roin, 
ii little more than the to the end of the anus. Tin* jiular fold is very 
ilistinct, and even overlappinji'. The };ro(»ves behind the jaws and from 
the eye, oblicjuely alonfj the side ol the head and neck, are also very 
strongly marked. 

The eyes are moderate; not prominent; the pupils circular. They are 
distant from the nostrils one orbit lengtli and separated anteriorly '2k 
oriiits; the nostrils art' separated one orbit. There is a decided con- 
striction at tin; neck. 

The body is swollen and Iar};e, a little di pressed; its circumferenco 
at the wulest is nine li'Uths the distance from sui ut tn ;4rnin. There 
are twelve well marked costal furrows from fore to hind Wy:, and live 
pelvic: the foiiiih and tiftli unitin<;' just Itehind the anus. 

The tail is about cMpial to the distaiu-e from snout to j^iitiu; it is sub- 
quadrate at base; l.\ as higli as widt', but iiccomcs iMUiinliately oval in 
sectittu, larjicr below, and more and more comprcsMMl to ilic tij'. The 
<'d;;es arc, however, rounded to the terminal third, wheie tlie\ ;^radually 
becomi' sharp. 

The leys are stout, thickened, and lather sliort in proportion. The 
di;fits are much depressed; short, tiiauiiiilar in sliaoc. tapcrini; from 
the broad oase to tln' tips, which are lianbiu'd and soniewhal horny in 
ajipearance. The tree porti( n of {\\v lou;.;cst is about one tliirtl the 
total len;;th of the liml> from elliow »u' kut ( ; soiiu'tiuu's even les-;. In 
the individuals whicli live on land the di;;its appear louder and more, 
eyiiinlrical. The expanse of the ontstretchcil toes is aiioiit four tilths 
the distance from snout to ;^roin. 

The ton;iUe is lU'sliy, iuDad, altoul half the width ol the head, ami 
with the outline of the papillose portion siiglitl\ eniar;;iinite behind. 

Th(^ palatine teeth of this spech s e\ten<l aeioss :he palate very 
neail\ from one side of the upju'r jaw to the othei-. The series is 
tuny inleiiupted alony tlu' nu'dian line: sometimes scarcely so. TIh* 
iini' is obtusely an;:ularly loumled aiiterinil\. the concavity behind 
riMciiing' forward to alxuit (tpposite the middle of the iiifeiiial iiares. 
The slij;hlly convex anterior luam-hes divei'^-e backwards regularly 
nearly to the line of the inner narcs. where the aui^le of diverj^ence lie- 
•!omes still yrealer, and the line l>ecomes lu-arly straiyhl or even eon- 
cave uiiteriorly.

There is some vaiiatioii in the .specimens, of tlie pieci,-,e outline of 
tbe onrve of palatiiu- teetn. Sometimes this is less an-ular anteriorly 
iiud does not reach lie.voiul the posterior 1 order of the inner nares. 

Ill life this species is of .- dark, livid blackishhrown above, oliva- 
ceous on the sides, and from lijihl olive to dirty white beneath. On the 
upper surface, ^uencrally on the side of tiie tail and limbs, are nearly 
circular yellow spots about the size of the eye, and j^i nerally sharply 
detined. These aie iiiucii liUe those .)f .1. piinvtatiim, though not (piite 
so distinct, and althou-li a fi'.int indication of airan}>vmcnt in ten dorsal 
rows may be traced, yd liiesc are less symmetrically disjiosed, and sin- 
gle ones "are sc;ittercd lift wi en thcotiicrs alonji' the back. Similar scat- 
tered spots are seen alon- the belly, wiiich af-ain is bordered, as on the 
lower part (»f the sides, with larger, more (piadrate si>ots, which are 
more or less conllnent. giving rise to elongated blotches, overpowerinpf 
the "iduntl color. This is also sometimes the <'ase on the l)elly and 
almost always on the chin or lu'iieath the head and neck. 

The rounded spots above souietimes vary considerably in size, and 
occasionally are almost wanting. Sometimes they are iiKue or le.ss c(Ui- 
fluent, in which ca.se there is u.>ually a predominance of yellow <»n the 
bellv. In a large series of specimens I have not observed any vertical 
yellow bamls on the side of the tail. 

In the young, jrst peifected from the larva, the upper parts are d:irk 
bidwii; the under jtarts of a miifoim browiiishyellow. The yellow- 
spots next make their apiiearance, liecoiiiing more and more prominent 
to a certain age. In very old spcciiueiis the dorsal spots be.ome in- 
distinct, but may generally be discovered when held under water or 
alcohol.

III this variety tlio nppreciable diflVTOiice in color consists in tlio teinl- 
ency to transverse or vertical bars of yellowish on the side of the tail 
more or less continent. 

I tind no ditference in form between the two series, the snpposed A. 
I'lmcopum now at iniiid (.{SiM) and 38S7) and young specimen oi A.luri- 
(iitm (as .'{J)?!), Irom Marietta, Ohio. The color above is a light reddisii- 
brown ; tln^ sides a sharply delined dusky l)rowii ; th<> belly of a lighter 
shade of the color of the back. There are some very obsolete indica- 
tions of whitish spots in tiie belly and sides. 

Tiie following eximination of the nature of the variation to which 
the Eastern foi-m of this species is subject and their <!auses may be 
a«lded to the preceding diagnosis from liaird's manuscript. 

The color varieties are as follows: 

rr. Uniform brown above, yellow below, sides darker brown ; 3S87, 
381)!); three specimens. 

fi. Blackish-blown, with sniail scattered yellow spots above and large 
ones on the sides, in the majority of tin* individuals; Nos. 4003, 4()!)7, 
4(591, 3!)74, 38t)5, li'Mi, lim.i, 3!)70, ;{•.).">(), 1»{)71, 401)2, 47()(i, and eight in 
in museum of the i'iiiladelphia Academy.

deep brown ami bright yellow ; 40.")!). 

6. Entirely yellow, with brown linear patches irregularly arranged; 
type of ^l. imjfus, from New Orleans ; one specimen. 

The above <!oloration varieties, it will be observed, coincide in part 
with those of Western individuals: 

The conditions of preservation of immature stages in the dentition 
are as follows : 

a. Palatine series nearly entirely transverse behiinl the internal narcs; 
eight specimens, all from New Jersey except two from Root liiver, Wis- 
consin, (I0!)3(/), and cme from Louisiana, 470G. All are fully developed 
and many ot the l.irgest size; one of 4()!)3 has the postnarial denial 
series separated on om^ side. Of these the largest example of the sjie- 
cies is frcMii Root River. With the other mentioned, the width of the 
head enters the length tit the groin 4.5 times, and the tail is longer than 
head and body. Tiie same relations are seen in two New Jeisey speci- 
mens. Two from the latter State have the long tail, but the width of 
tlu^ head is only one fourth length to groin, while one of the same has 
the long«'r body (4.5 times), but the tail shorter than head and body: two 
specMinens have both the short body and tail. The elongation of the 
tail and body scarcely occurs in connection with any other ty|)e of deu-

From iIh' preeediii;'' investijfation we j;allier that laival eliaraeters in 
this speries are in part only eoiitempoiaiieiMis ; that the branehia' arc 
lost (list; the toiiuiie develops next, and the te(!th last; that the de- 
vel(»piiiei!t extends in older a^e to the leiij^lheiiiiin' ol' the i)ody and tail; 
that the pro^^ress may be arrested at a time when any de^^i'et' of eom- 
binatioii of these and other fealiires exists. That reprodnetioii may 
take place at any of such dilVerent sta;;'es iseviileiit from the condition 
(»f development of the ova ol' many ot' the various specimens, and it 
is known to tak«' phn e in other species at earlier .slaves than any re- 
eonled heie as juiiiit. 

It is also to be noted that specimens from New Jersey are almost 
always more liill\ developed than those from the Western rej;ioiis; the 
former is a wan. lei district than the latter. 0| two specimens from 
New Orleans, howexcr, one only exhibits the deiititiona! charattter.s of 
the New .leisey indiviilnals. The characters coinmon to the Western 
individuals iiave occasioned the opinion that it was another species, 
which was called A. iiKiroiiiiiiii. 

Of this l-rm i r*'maikedin my moiio;;rapli of the j-eims Amblystoina, 
published in lSi7. already referred to, thai it "dilfers absolutely only

view of the irlalions of the l^istern and Western forms. 
The fol lowing' is a desi;iiptioii of a specimen of tlie Western animal: 
Talaline teeth in a transverse series, more or hvss aii;inlar anteriorly, 
reaching"' to the posterior l)or(h'r of the inner iiares, or (»ne diameter be-

which are jicnerally a little iindnlalin^'. 

Inner nostrils separated hy the same space as the outer; rarely a lit- 
tle larther apart,

tail, I'xtciHliiif; down on tlic sides as tiaiisverso ellipsoid bauds of 
lai'j;e size, perhaps equal t(» the spaee between I wo costal {grooves; the 
bIol(^hes of opposite sides scuuetiiues alternate, sonu'tinies are opi)osite, 
and are I'nMpuMitl.v eonllneiil here ami there, which is ^'enerally the 
case on the tail, where they form yellow eneirelinj; riujjs, interrupted 
below. Alonj; the sides ol" belly and lower part of the sides is ii sinii- 
lar series of yellow ellipses, but usually lariLM'r; those of the same side 
usually somewhat eoiilluent, .soiuetiuu's entirely so, leaviufjf a du.sky 
central Hue of the belly. The limbs are blot(!he<l black and yellow. 

The yellow sometinu's predominates so as to abuost Ibrm the fj^rouud 
color, encr()achinj>' lai'^'ely, too, on the yt'llow of the belly. In general, 
however, there is little or uo tendency to an anastoim)sis or reticula- 
tion of the dark intersi»aces, as in an allied sjx'cies. Smaller, rounded, 
irregularly scattered spots of yi'llow are seldom, if ever, seeu as iu 
Eastern form. 

The ground C()lor is sonu'tiuu's uniforndy dusky above, although the 
lighter transverse ellipses can be usually made out; perhaps they are 
always apprecial)le in life. 

Dunuh'il and IJibrou have given a good colored ligure of this form 
under the nauu^ Amhi/stoinv <i' bdittUs. The green is, however, too bril- 
liant. 

In the pre(!e(liug general description I have endeavored to represent 
the distinguishing features of what 1 believe to be a single species vary, 
ing very much in shape of palatine teeth, proportions, color, etc. From 
the synonymy it will be seen that 1 combine undej' the oldest luinie of 
mai'ortium, pninrrpine and nrhiilnsitm also. Although the type speci- 
mens of these supposed sjiecies dilfer sutlitnently among each other, yet 
there are sullicient coniu'cting links in tlu' large series before lue, ami it 
M()uld be no dillicult task to pick out a dozen more specimens each as 
distinct from the other and the above as the latter are among them- 
selves. 

One great source of the diversity of character in diiVerent specimens 
of this Protean species is to be found in the veiy dilferent sizes of speci- 
mens in thesanu' stage of growth, while iu some the lull metamorphosis 
will have been atu-omplished with a length of three or lour inches, in 
others the braiichi;e are still visible at a miu-h greater size. In one 
female specimen of 8 inches in length ( 1*>7S), the branchiae are still a[>- 
piei'iable, the lissures in the neck not being closed up, although the 
ovaries and oviduct would indicate that it was captured when in full 
breeding (tonditiou. Thisembryonii' tendency isalmostalways indicated 
further by shoiter gape of the mouth, the tongue smaller. Hatter, more 
.idherent, not at all or very little free at the edges, ami little or not at

teeth in the embryonic stati' are more aiclied anteriorly, more or less 
parallel with the maxillary seri»'s. less |uominent above the soft palate, 
and extending a less distance laterally. T'he digits are more depresed,

tl.cir outlines more oval tlian triangular, the third and fonrtl. toes and 
second and third lin-ers more nearly .M,nal. The develepn.ent ..( the 
diin-rent embrvonic eonditit.ns mav be carried on ver.v nne(|nall.v in 
dillcrent specimens, so that one cannot see the true specilie charac- 
ters in small individuals, or even in lar-e ones in which tiiere is the 
slij,'hfest indication of the brandiial slits or their tults. 

The same adult individual ditrcrs, too, in dillerent seasons. While 
somesi)ecies appear to reside almost entirely in water, others do so only 
partially. Kven the same species may pass a more aquatic lite in one year 
than in'anodier. A more i)ersisteiit residence in water is shown l»y tlio 
broader and more depressed (li;,'its, Iiij;herand more compressed tail, and 
more or less decided ridjre (sometimes even membranous). I have no 
doubt that an animal while possessinj; these Ceatiires in marked decree 
when in the water wmild lose tlieiii to a measurable extent after ii 
Ienj;lhened residence on land. This aijuatic habit is j,aMierally greatest 
(hiring the breeding season. 

The preceding paragrajdi is taken from Professor liaird's maims«*ript. 
I will further extend and illustrate the same, and add that the names. I. 
calij'ornicnse and A. iiutvuhttum have iteeii applied by (Iray and llallowidl 
to forms of this species. 

Various changes of form during the late metamorphosis of this ani- 
mal have been already enumerated in the prefatory remarks on the 
genus. A feature of diifeitMice mentioned altove -the varying length 
of the fourth <ligit— ai)peais to be ipiite independent of other devel(»p- 
mental conditions. In a specimen in the Mnseuin of the Philadelphia 
Academy from Kansas, thi.s digit has but three ithalanges on both feet ; 
in another locality three on one, four on the other foot, and tiie same 
occurs ill No. .'{!M»4, of the National .Mnseuin. In all the other specimens 
at my disposal they are, as in this section of the genus, \-\. 

The varieties of this species which may l)e distinguished by their 
coloration are as follows : 

a (Californieiise.) IJlackish, with slightly i)aler belly; a series of 
large, oval, yellow spots on lower part of side and tail (in one specimen 
a few on each side of dorsal line). System of nuieous por«'s well (h>vel- 
oped, especially below ramus of the Jaw on each side. From California 
only ; eight specimens; No. lO.Sl. 

fi Brown, yellowish below; larger lateral and smaller dorsal yellow- 
spots, irregularly arranged. Fewer miu-ous pores (»ii eaeii si<le the 
gular region. Fourteen siiecimens ; mostly from Kansas and Nebraska, 
one from Missouri, one from latitude ;>,So, two from New Mexico, and 
two from Chihuahua; Nos. lOfJo, 4()i(», 3!t.o5«, 1(m;-J, |(l.S4, l!)(>S, ;5!)S|«. 
The type of A. uehnhmnn belongs her*'. There is no material diUerencc 
between this and the coloration of A. t'uirinum.

I add lieie a description of the var. ohseninm {AinhlyHtoiiid ohsritrinn 
Haird, Proceeds. Acad. I'liila.,. IS(i!», p. 1!L'). 

The head is very l»road and the ;;ape nniisnally lar},'e. The internal 
nostrils are veiy huj^i', their width half the diameter of tlioeye; the 
distance between their inner borders is the same as that lu'tween the 
oilier. The ton^Mie is Ia!j;e, broader than lony', its width about two 
thirds that of the iipiicrjaw. 

The palatine teeth are in I iiir series, eolleelively foiinin;'' a broad in- 
verted V; the an;;les anterior, and would beqiiit<' sharp but that there 
is an iiileriiiption aloii;: the median line. The blanches reach as far 
forward as tlieanteriorl»oidcr of (lie inner nostrils. 'J'liey are decidedly 
concave aiitero-e.xicrnally. The ten iiiiiei anterior sections of the pal- 
atine scries are each about twice the lcii;;th of the external ones; they 
fall short of the inner border of the inner nares by nearly a diameter of 
the latter, which space separates them from the outer section, which, 
iiiiiijcdiatcly lichiiid the inner nares, are about as loii^ as the latter are 
wide, and do not pass exterior to their outer border. 

There are twelve costal furrows. The tail is compressed, Init not 
hijih. 

The C!»1(U' ai)pears to have been of a uniform brown above and on tlio 
sides, brownish yellow beneath. On the sides daiker vertical blotelies 
can be detected in the sinjile specimen before me. Similarly indistinct 
markiiij^s are visible on the tail. 

The \ery convey, frontal re;;inii and the concave interrupted .m lies of 
teeth alone distinjiuish this variety from the .1. t'Kjrininn of the West. 

It dillers from -I. //7/»H»«n»f the Kast in much larjier inner nares 
and more widely .separated nostrils, tiie inner borders of the two beinj^ 
at about the .same distance, instead of liavin;; the latter more approxi- 
mated. The toii;jiie is wider, as well as the liea I. The teeth are more 
V-slnipetl and roach farther forward. The outline of the limits of the V 
is concave antero externally and is interrupted by spaces equal to the 
wide nostrils, the outer section not extending' itcyoiid the nostrils. 

The specimen which lepie.sents this variety is Irom l-ort Des.Moiue.s, 
Iowa (No. auOi.)

parotid rej^ioii. Some pores, however, are distimitly visihh". behind tlie 
aiifjle of the mouth, sending forward a seiies ah)!i;; the iiMrj^in of tlie 
lower jaw under the tdiiii. 

The head is broad, but also h)nj,', the width beiiiji" decidedly less than

len}i;th nearly two-thirds the width. The width in seven spi'cimens is 
contained \h tinn's in the distance (rom snout to fjroiii ; in one s[)eciineii 
4 times only. The eyes are separated only by 'IK lengths of tlu^ (U'bit. 

The t(Hi;.'ue is very larj,fe, nearly lillintj the whole lower jaw. It is 
three fourths the widtii of the head. 

There is quite a dill'erence in the character of the palatine teeth of 
the ten specimens before nie. In both the central jtart of the series lb. ms 
a decided V> ('>*' nii;;le siiarp, and reaching to tlie anterior margin ot 
the inner nostrils. The limbs extend backwards, sli^'htly in an 3 shapi', 
a slnu't distance behind the inner nostrils and in line with their inner 
border, and then connect with the external sc^nieiils of the jialatine 
series, which extend (iie.irly transversely, but a little obliipiely back 
wards) to a line with the outer iiiarj;iii of the inner nostrils. In both 
specimens the two sides (»f tliepalariiie seiies a;e lui synimetrical and

the central V i"i<l <''<' hiteral sejiiiieiif. as well as at the an;;ie of the V; 
ill the other the four elements are contiiiiioiis. 

Then' appear to be twelve costal furrows. The tail is compressed, but 
not lii;;h; in one specimen it isas loii;i as head and body; in another 
»Ii(»rt»'r. Shows a slmrp rid^i'c above from near the base ;i!id for the 
terminal half below in oii(> spetamcn; not so much in another. 

The limbs are well developed, the di;;its depres.sed ami trianj^ular, 
but le.ss so than in many atpiatic Anihlii-stnindfa, 

The (M»lor of the sjiecies is blackish in alctihol ; rather i)aler below. 
On each side i>\' the belly or lower part ol tin' sides of body and tail is 
a series of brij;lit sulphur yellow spots, mostly nearly circular, .some- 
times obloii;;, and varyiii}? in size, tlioiin;|| ^jcnerally lar<;er than the

four or live on the side of tail.

I'riH (Is. Aciiil., riiila., Hti7, |.. I'.U. 

Tlu' species is stout and lieav.v in ItniM; llie lieail \eiy liroad nnil 
niiieli (lepresscd. Tlie sliin is },nannlated I).v citntraction of the alcolml. 
but in respd't lit jilaiids, pits, etc., appears niiicli like otiiei species. 
Tliere is, lidwever, a de(!ide(l realiin' in ccitain particles wiiicli eiinvd 
tlie paiotoid re;:ion, and are seen also on tlie top of tin- head alonj^ the 
inner inarjiin of the orbit, and perliaps below the ev«'. I liaxc not 
noticed this character in aiiv otiiei' species east of the itocky Mourdains. 
The head is bioad, ovate, ratiier ]>oiiited anteiiorl.v. The inner and 
outer nostrils are nearly the same distance apart. The tonjiiie is broader 
than loiifj', more than half the width of tlie head, lillin;; the intersi)ace 
of the same anteriorly. 

Tl»' teetli are in Ibnr very distinct patches, with d»'cided intervals. 
Thoy form one tr.insveise series, nearly straij^ht (teiitraily (where they 
are in a line with the posterior Ixtrder of the internal iiares), but ciirvin;; 
slij,ditly backwards lateially. The two central patches aie wider than 
the lateral, which vaiy a little in Icnutli and are separaled by iiii inlei- 
val half the diameter of the inner nates. Their fjistance from the exte- 
rior patches is al>oiit twice as j^reat, the center of the interval falliiii; 
about ()pp(»site to the inner bolder of iiiiiei' iiares. The outer patches ex- 
tend about half a diameter iteyond the outer border of inner iiares. 

The remaining;' external cliaractti'is of the speciincn are not dill'eieiit 
from those of .1. lifiriinnit. 

The colors of the specimen are much obscured by bad preservation. 
It appears to have b(>eii of a iiiiiforii) dark blackisli or bluish brow n, with 
a sin;;!e sei'ics of lar^c transversely elliptical blotclics of yellow from 
head to tip of tail, half on body and half on tail; the foremost one 
rounded and ]>lac(Ml behind the eyes. Those of opposite sides nearly 
meet on the back, and aic c(Uilliient on the iipi>er cdyv of tlu' tail. 

This is the only species I have .seen of the ■;ioiip in which a strictly 
transverse series of palatine tee.th behind the eye is divided into Ibnr 
{ironjis. 
The only known specimen is the Ibllowinji : 
No. KKiS; 1 speciMicii ; ( )cate Click, New Mexico. 9.

(Jencrall.v the f,Monnd coloi of the alcoholic specimen is lead-colored

This is a vi'ry (elongate form of the .1. Jcjlarxonianum. 

The head is oval and the muzzle rounded. The lengtli (»f tlu' fissure 
of the eye e<pials the distance of the nostril from the same ; is but little 
less than the di.staii(!e between iiares, and half or a little ukuv, of the 
distance between tlie anterior caiithus of the same. Inner and outer 
nares the same distane*' apart (Ireatest width of head "».,") to six times 
in K" gth from end muzzle to groin, live sevenths lejigtii from chin to 
giilai i'old. Canthus of mouth behind canthus of eye. A series of 
l»oies along the superciliary, which pass round the orbit Iteliiiul and 
below; a scattered longitudinal .series on the parotoid region, and a 
traiisver.se aggregation of the same on each side below parotoid groove :, 
a single series of the same for a short distance inside tlie ramus of the 
mandible. The parotoid i-egion i»ossesses a thin stratum of dermal 
crypta'. 

Costal folds twelve. The anterior is a little distance behind the axilla. 
T\)es subeylindri(t, similar {o those of the A. j<'ll'<rN<>ni((nitm: in one 
specimen (ty[>e) they arc separated by nearly an intercostal spa(!e when 
lh(^ limbs are pres.sed to the sides; in another they me»'t. Tail rounded 
above at base, liiially much compre.s.sed, but not elevated; iMpial in one 
specimen to body and head to middle of orbit, measured from posterior 
extremity of vent. In the type, however, it is much shorter, extending 
from its basis <tiily t(» the eighth costal fold (from groin), but I suspect 
that this is altnormal. 

Color leaden ; in tyi>e paler below, with numerous indistinct whitish 
blotches. I"]yelids yellowish margined. S[»ecinien 4(>.SS has the abdo 
men darker and without spots. 

The nar >wer head ami more elongate body will tlistinguish this 
species from the typical A. Jr()'ersonitniKni. It is readily distinguishable

This species is the shMidei'est ol' all our spceies of Ainblifstoina ; in 
this respe'it, as well as leiijith or(lif>its, ex('eeirni,ii' the t,vi)ical A.jcffcr- 
noniitnuin, but I'eseiiihliii};' the A.J. plutinciim. 

The head is rather larye, <lepiesse(l, and eloiinated, with a iiiodeiate 
eoiistrictioii at the neck. Tiie eyes are proniinent, and distant less than 
two leiiju'ths of the orbit. The outer anil inner nostrils are each about 
oint orbit distant. The width of the head is about three-cpuirters the 
distance to j^nlar fold. 

The lonj;ne is oval and longitudinal. The palatine teeth are in three 
or four patches, the central largest, occasionally sei)arated by an in- 
terval less than half the diameter of the inner nostrils. Together they 
form a line slightly angular anteriorly where they reach to about op- 
l)osite the (!enter of the inner nostrils; laterally they pass a little the 
outer margin of thc^ inner nostrils. 

The body is cylindrical, depressed, with twelve costal furrows. The 
tail is long and is com[U'essi'd for its distal half. The digits are longer 
than in any other spec", s of tlie genus, the interior being well developed 
on both ext rem ties. On the forefoot it eipmls the extern id toe in length, 
while (II the hind limb it is a little shorter than the lifth. The pha- 
langes are : In front, 2, li, .{, 2; behind, 2, 2, 3, 4, 2. 

The cnh)r in alcohol is leaden brown, with a well-defined broad dorsal 
stripe of grayish-brown, which, involving the whole upper surface of 
the head and neck, contracts on the nape, swelling again on the back, 
with an average, breadth of the outer orbital space. This stripe extends 
to the end of the tail. On each side of this dorsal strip(^ is a sulfusion 
of dark brown, which gradually i>ales through the color of the sides 
onto the belly. There are also a few s[»ots of the satne in the dorsal 
stripe. There are a few grayish-white dots scattered along the sides, 
and perhajis on the limbs. 

Two specimens (Kt54) from I'ugi^t Sound agree in Ibrm with the 
preceding speitiiiu'ii, the two central patches of i)aliitine teeth perhaps 
a little more, angularly arranged. Instead of the grayish dorsal stripe, 
however, there is a brownishicd one, and the sidi^s areof a darker and 
inon' (!ontinnoiis brown. No. 1711 has a similar eharaitter of palatines, 
but a coloration mort^dvc the type. The palatines, in fact, extend a 
little in front of the anteriiu' border of the inner nostrils.

This species is in all respects more robust than the A.macrothu-ttfhm, 
and is more brilliantly colored. Its tints are (hose of the Kun.pean 
SaUmandnt ni<iculi»s(i,iuu\ are bri};hter than (Iiose of any other species 
of the j-enus. Its hyoid apparatus is represented on IMate L';{, tij,'. 8.

Otog'.ossal cartilajj:e trianj^fular, attached by a base to each side of the 
Jiyi)obranehial cartila{;e. 

in otlier respects this genus agrees with Anddystoma. The larva of 
the type species {C. tcnchrosus), the only one I have ideiititicd, dillers 
from tliose of AmbUiftoma in the absence of basal branchial processes, 
and (tf spleiiial teeth. (Plates L'O-LM.) 

1 have examined the hyoid apparatus of the sjiecies of this genus, 
and 1 refer two others to it. One of these, (\ vhujuhttns, very probably 
belongs here; the position of the otlier, C. tc.vanus, is altogether uncer- 
tain as yet. 

Considered with lespect to the forms of their otoglossal cartilages 
tiiese species fall into three sections, as follows (see IMates LTj and L'(J): 

(I) Tlie cartilage uninterrupted in front. C. (cntbrosus, C. aterriniKs. 
and V. ilrvortiaitits. (Figs. 1, '1-5, 8-".».) 

(•J) Tiie cartilage divided in front, and without median processe.s. (J. 
2)<n-oticu>i. (Figs. 0-7.) 

(.'{) The cartilage divided, each half with an internal and external proc- 
ess in front. (Figs. 1-2, I'l, 2().) C. microstomits, 

111 addition to tliese characters, it may be observed that in the C. 
tenchrosus and C. dterrimus there is a sheet of strong librous tissue 
extending antericrly from the otoglossal cartilage, and forming the 
base of the tongue. A few similar fibers are found in the correspoiul- 
ing position in the A. pary>tk'iim. 

IJesides the characters of the otoglossal cartilage I have already 
given, I may add thac in the species with entire anterior border, the crest 
of the superior surface of the basibranchial appears to pass through a

folds are fourteen, and are visible across the abdomen. 

The liead is clonijate, eonvex both transversely and loui^itudinally ; 
the upper face of the muzzle is narrowed, and projects beyond (he 
mandible. The width at the Jaws enters the lenjith to thi! «;roin (i\

This salamander is of very i)ecnliar (iharacter. It is one of the stout- 
bodied spe(!ies, in this respect about e(]nal to A. piincttitum, but with a 
broa(b>r head. 

In the type specimen (47(t8) the skin is remarkably free from pits, 
pores, and milk olands. Tiiese are found on the parotoid region, both 
above and below the horizontal furrow from eye to side of neck, which 
is swollen in conseiiuence. There is also a small patcii on top of head 
borderiii};- the orbit, a pat<-h on the s|)a<'es between the intercostal fur- 
rows, on the ujyper pint of the sides, extending-, though faintly, nearly 
to the belly. Along the ridge of the tail, bordered below by an in- 
dented line, the glands are tliickly crowded. A few scattered glands 
are seen along tlie back ; elsewhere the skin is perfectly smooth and 
glandh'.ss, with the miisch^ directly beneath it, although probably when 
fresh the usual shallow pits of tlu' group stud the skin thickly every- 
where, as usuid. These are distinctly visible in a second si)ecimen 
(I7(t!>). In this also the ghuuls an; more numerous on the back and 
extend fart her <lowu the side of the tail. 

The head is Itroad and depressed, considerably constricted at the 
neck. The eyes are unusually large and prominent for the genus, sepa- 
rated ant»Miorly by about twice the length of their orbits, distant from 
the nostrils less than this lengtii. The outer ami inner nostrils are 
respi'ctively about equidistant by little more than one length of the orbit. 

The tongue is moderate, m-arly circular, tilling the rami only ante- 
rioily and hanlly more than half the wi<lth of the head. 

The teeth are in four patches, forming a transver.se series, slightly an- 
gular anteriorly, where they extend to about opposite the centers of the 
inner nostrils, 'i'ju' two central piit<!hes are rather the larger, with a 
slight interval. Tlicy extend jxtsterolaterally nearly to the inner 
margin of inner nostrils; then ai-e se|)arate() from the outer patches by 
an interval nearly the widih of the inner nostrils. The lateral patches 
extend a short (listance bevond the outer margin of the inner nostrils.

The para spl.enoidal imrlion of tlio roof of the moiitli is imicli re- 
stricted laterally and behiiul. 

The body is full, rounded, anddei)ressed. Tiiere are eleven costal fur- 
rows, including iu'juinal aiul axillary. 

The tail is compressed, but oval in cross-section, with the lower edjio 
rather sharp towards the end. Tiie upper outline is much rounded, it 
is iu)t hi-ii, and not as long' as the rest of head and body; longer than 
from sntmt to groin. In one specimen there is a distinct furrow along 

the under side. 

The limbs are large; the digits lengthened; more depressed than in 
A. piinrtatum, but linear, not triangular in shape. Tlie lateral ones are 
more lengthened than usual, and those of each limb ure more nearly of 
a length? The free portion of longest linger is more than one-third 
from tip to elbow; that of longest toe in the same proportion. 

The gape of the head is wide; the length more than half the width. 
The width of the head is contained four times in distance from snout to 
groin.

Tlii.s species has a {jood deal of allinily in its character to the C.

as in its external appearajice.

head is short and the muzzle is contracted, ami is steeply rounded in

There is no eantliiis lustralis, ami the lower jaw does not extend be- 
yond the upiKT. The external iiares are almost terminal, and are as 
far apart as the distance b.'twcLMi the inner bordiM'S of the choana'. 
The latter are rather lar^e, and are transverse. The vonieropalatino 
series of teeth form a short transverse line, which is entirely within the 
internal borders of the inner nares and a considerable distance poste- 
rior to them. The ton,-;ae is wider than Ion;;-, bnt docs not till the wide 
floor of the mouth laterally. A dermal yroove extends posteriorly 
from the eye to the side of the neck above the anterior border of the 
liiunenis. A branch groove descends a short distance posterior to the 
eye and turns forwards to the eanthns of the mouth. These grooves 
divide masses of crypts, those on the inferior side of the {groove hi'.\u<r 
most prominent. The tract above the groove resembles the parotoid 
ftland of the Vliondrotm parotiviin, bnt is much less distinctly <lelined, 
fading out upwards.

color is represented by a dark chocolate-brown, and say that this is 
closely studded with brownish-white spots of irrej;nlar forms and 
sizes. On the back, limbs, and top and sides of the head the pale 
spots are so close tojjether as to reduce the brown to a network. On 
the l\nM-leos the p.ile spots arc lar<»er than anywhere else. The spots 
are few on the tail, and those chielly near the base. The inferior sur- 
tiUH's are dirty lif,ditbrown. 

Tiie characters which separate this species from C. j;<no//VM.s' are: 
The inu(;li shorter series of vomeropalaiine teeth, the shorter lin,ners

This is a stout spe(^ies, haviiifj; a form of head intermediate between 
that of tlu^ C. fenebrosus and .1. tiyrintim. The deidition is (piite pe-

immediate neiyldiorhood of the C. ienthiosus. 

Head a broad oval, its ••reatest width a little over three-quarters the

pupil marks three-sevenths the distance from canthus of mouth to ex-

The tail is short and stout; its upper edge is much coini.ressed, as is 
the i)osterior half; its glandular structures are much less developed 
than in other species of Amblystoma, the erypts of the erest being 
minute and globular. Length of tail e(pial from its origin (posterior

This .species is csiu'ciully cliaructcri/ed by its iniussive fVaiiie and huge 
si/e among tn <> salamanders, as well as by other peculiarities, liereafter 
to Itc mentioned. 

The skin is less glandular than in A. pnnctatiim or ^(^r/«jn)i, although 
scattered glands may be detected (closely and evenly distributed on the 
wlioh' back ami sides and on tiie chin. The remaining under parts and 
snout befiu'e the eyes are smooth. 

The head is v«My massively built, large, broadest behind the eyes and 
triangular, the sides being nearly straight to the narrow and roundt'd 
tip. The eyes an; very large and prominent, se|>arated by less than 
two lengtlis of the orbit, ami distant less than one length from the outer 
nostrils, which arc separated by \\ orbits distance, and placed on the 
side below the distinct eanthus rostralis. Tlie outer nostrils are much 
more distant tiian the inner, which are very large, much excavated, 
and iiave the external canal occupied by a soft, plaited membrane. 

Tlie tongue is thick and tleshy, nearly orbicular, but angular anteri- 
orly. It tills up the lower jaw pretty well, and is more than halt' the 
width of the head. 

Tlie palatine teeth are in two patches only; each very slightly convex 
antericu'Iy, coming together at a slight angle, with the apex backward, 
l)nt separated along the nu'dian line. Lateially the patches of teeth 
form the p(»sterior margin of the inner nares, and do not extend beyond 
their outer margin. The eidire .series is thus posterior to the nostril, 
in younger specimens the series are more transverse, the inner extrem- 
ities slightly incurved. 

The width of the head is contained 1;^ times in distance to gidar fold 
and 4 times to groin. 

The l»ody is roumled and depressed. As nearly as can be ascertained 
there are about twelve costal furrows. 

Th(^ tail in the two specimens before me is considerably less than half 
the total length. It is much compressed from near the base, and the 
edges near the end are (jnite sharp. It is far short of being as deep at 
the base as the body. 

The lind)s are stout. The digits, the fingers especially, are short, con. 
sii'erably depre.s.sed, but linear ami blunt at the tips. The under sur- 
faces of these are souiewhat swollen into a kind of bulb, which in alcohol 
contracts into something the appearance of a disk. The third finger is

The tiiil lias a liii at its oxtivinity, wliicli extends also wi'll aiiti'iiorly on 
tho snpeiior t'd;;e. The dij^its arc Ihittcned, and their apices are pro- 
tected in many specimens by a liorny cap of a blackish color. This 
larva, however, dillers lioni that of other species of the ;;cnns in otlier 
characters of more iniportance. First. There are no teeth on thesi»Ien- 
nial bone. (I have not examined very small specimens.) Secondly. Tln^ 
branchia- have a peculiar shape.* There are no processes such as exist 
in all other Urodcle larva-, but the linduia' arise from the edj^es of tlie 
vertical lamina-, which separate the pliarynj,'eal lissnres (Fi.i;. 3, p. ,'{, No. 
7). The superior ))art of the lamina is a little more produced than the 
inferior, so as to form in some specimens, on the third lamina, a short 
ju'ccess. This type of external branchia- do(-s not n-semble any of 
those of the perennil)ranchiate types, where theie are always \mH',- 
esses which are fre(piently furnished with more or less numerous rami. 
Thirdly. The teeth of the larva are stronjicr than in the adult. They 
are compressed, doubleedj^ed, and acute, liavinj,'' thus a da.y<;er shape. 
They can iullict a severe bite. 

As they approach maturity the marbled (-olois be^in to appear. 
They can probably reproduce without under^oin^' a metamorphosis, 
since I have found e;ij?s in the ovaries ready lor dc])osit. 

I observed these larv.i.' in some tributaries of the ^IcCloud IJiver, 
near Baird, Cal. They swam with .ureat rapidity, darting' about and 
hiding tlemselves amonj;' the fallen leaves that covered the bottom, i 
took from the stomach of one of them a larva of its own si)e(!ies (»f on«-- 
third its size. They are common in the mountain streams of northern 
California-aud western Ore<;on. The skeleton of a lar^e sjtecimen friun 
iSalenj, Oregon, is li^'ured on Plates L'O-L'l.* The hyoid apparatus of a 
youuger larva is reprcscuted ou PI. 22, lijjs. L*-o.

The latest work on tliis subject, tliat of Doulenj^tM', throws iiiuch 
light on it, owiiig to the opportunities on.jcyed by its aiitlior for the 
study of the forms of salainaiulers found in Asia. He gives the follow-

sonielv coloiTcl. All arc (li><tingui.shea for tiieir poworof projoctingtlio 
toiKMio. Some of H.e spocios of Spclerpes, ul.erc tl.is organ is free all 
ronml, can i-r.^jcct it ontirely from the i.iontli, xvhilc the acotntonfuscm 
has almost the power of the chameleon in this respect, projecting the 
tongue for a .listance equal to one-half the entire length of the am- 

mil * 

Appropriately to this habit, the basibranchial bone and its pair of 
short h.vi)olivarprocesses are free from the ceratohyals, thus admitting 
of free' movement, and the epibraiiehials are very long. In all of the 
genera the extremity o*" the eeratoliyal is attached to the quadrate, as 
bi the Aml»lystomi(l'ie. sliowing that it is not tliis element which is pro- 
ji'cted. Ibit in Geotnfon and Speler|)es sp. the epibranehial is greatly 
elongate, extending to the side of the nape and interscapular region, a 
structure necessaiy to projectility. 

Jn tlie characters of the sca])ular and i)elvic arches this family does 
not (IKfcr from the Amblystoniid;e and Salamandrida'. The foramen 
which sei)arates the i)rocoracoid from the coracoiil is well marked and 
interinarginal; in the Amblystomidie it is smaller, and .n the Sala- 
maiulrida- marginal. The femur always i)resents a strong trochanter. 
It is weak in Strrcochiln m<irfiinaiiiiii. In Trituriisand Diemyctylus it is 
(piite weak, but in Salumandra stiong. 

In most of the genera of tills family the enamel does not cover the 
entire crown of the tooth. In Siwlcrprs ruhcr, lo)){i>cau(his, and hcJHij and 
Pkthodon (fliidnosiis and cincrciis the external part of the crown termi- 
nates in a transverse cutting edge, while the inner extremity is more 
prolonged, leaving a transverse depression between the two. In Sp. 
hcllii the inner apex is transverse and prolonged a little beyond the ex- 
ternal, while in the other Spelei])es and the I'lcfhodon ghdinnNiis the 
inner crown is more prolonged and is incurved conic. In 1*. chwrciis 
it is a little more obtuse. In Desmognathiis and the Amblystoinida". 
the twoai)i('esare of equal height and are both transverse cutting edges, 
the outer narrowed in the former. In the larva- of IMethodontida' that 
I have examined the crowns are sim])le. The teeth of Autodax are 
more like those of Ccecilia, or of Ilylonoinusof the Coal Measures, and 
distiiiguisli the genus from other IMethodontida'. t They are large, 
com]>i'ess('d, and simple. 

Tliis fiimily is more remote in its skeletal (iharacters from the Sala- 
mandrida' and I'leurodelida' than is the Amblystomida'. Thus the 
absence of parasphenoid brushes, the ossification of the tarsus and 
cari)us, and (he persistence of the pterygoid bones aie characters eom- 
nion to Die two latter and wanting in the present fiimily. On the other 
hand, the nonprolongiition jiosteriorly of the vomers, the articulation 
of the ccratohyal with the (piadrate, and the ampliic<e]ous vertebra', 
belong to this family and the Amblystomida" only. The position of the

from the arj,nimeiit. Hero it can be safely asseitetl that, as far as tlie 
skeletons are concerned, there exist no other generic distinctions than 
those given above. If, now, any -ciples can be derived from consid- 
eration of the osseons system, th. ch of all others ])res(Mits ns with 

by far the greatest number of u\ .0 modifications of structure, the 

same may be with considerable probability inferred for the other sys- 
tems. 

The primary groups are distinguished by the different degrees of at- 
tachnuMit of the tongue. That form which is most attached rej)reseuts 
and is i(h>,ntical with an imnmture stage of the species of section second, 
where it is more extensively free, as any oneniay satisfy himself by the 
examination of a larva of Spelerpes at a certain period. The tongue 
will be found to be tlmt of Tlethodon. 

The secondary groups are distinguished by the separation or cou- 
Huence of the premaxillary bones. Those presenting the latter type 
exhibit separate premaxillaries at the beginning of larval life, though 
the union often takes place very early. The mimber of digits dis- 
tinguishes groups of genera of less value; in some tiie hind limb has 
five digits, in others four. In an early larval stage all possess l>ul four 
digits, and in some of those with live the inner consists of one i)hal;nige 
only even at maturity {Spdcrpes chiropfcrK.s ct. aff.) Not lli'.^ iug as c(mii- 
plete a series of larvae of Spelerpes and IMethodon as uf Anihli/stDiiKi 
imndatum, I describe the develoi)ment of the digits in the latter as iudi- 
eating the meaning of variations in the same at maturity. At a leugth 
of l.L"""' the fore limb only is projected, ami bears two digits only, as in 
the genus Proteus. At 1.5""" sometinH\s the posterior limbs are devel- 
oped, sometimes imt, and from this size to U.-'i"'"' the nund)er of digits 
bears little relation to the size of the animal, an additional digit sonu'- 
times appearing earlier, sometimes later. Their numl)ers aie then at 
first 2-0; then always 3-0. With the hind foot divided, they ar(^ .'{-L». 
and then ,'5-1. Sometimes the anterior digits are couiplete iu number 
before the hind limb api)ears, and we liave coml)iuations of numbers 
from 1-0 to 1-3, 4-t, and the full nund)er, 1-5, which is found in all 
specimens of 2.5"'"' and upwards, denera which exhibit reduced digits 
are in all other respects Spelerpes (/. e. ^Manculus) or Plethodon (lleiui- 
dactylum), or riemidactylinm with uuossified parietal bones and eonsdli- 
dated premaxillaries (Hatrachoseps). Api)lying the case of Anibly- 
stoina to tiiese, we could not assert that Ilemidactylium, for instance, 
is identical with the undeveloped stage of Plethodon, since when Ambly- 
stonui exhibits digits l-t it is branch iferous. IJi.t making the more 
legitimate eomi)arison with Plethodon itself, I find that the complete 
number of i)osterior digits appears much later in life than in Ambly 
stoma, while thebranchia' are absorbed much earlier; that development 
in the first regard is retarded, while in respect to the gills it is a(!cel- 
erated. Thus in riefhodon ciin'rcus the exterior digit is longer than 
the interior; iu si)ecimensof 2.1""" the outer di.":it is the shorter; in those

of l.S' , \vlii(;h jiiv witlioiil j;ills, it is ;i very minute tubercle on tiie 

outer inetiitarsiis. In ■'■. '■'tie eailier stiige it (t.iii not but be wantinj^, 
tlioiijjli this I liiive not seen, and I have little doubt that it is then a 
llernidaetylium, unless, indeed, the parietal bones be not ossified. 

Another fu'tal condition rendered pernianent is seen in the generic 
character of the <;enus (Hdipus, whi(!h dilfers from Spelerpes solely in 
the f«etal non-separation of the dijifits which continues even after the 
bones of the diffits have been developed. In the larva of Sp. ruber the 
digits are early entirely distinct, so that so far as this species is con- 
cerned (Edipus i)resents an inc.ract parallelism, but they are also 
nu)redistin(!t than in the mature ISpclerpeH beJlii, where, as might besup- 
I)osed, the fo'tal union is delayed to maturity in other respects, as ip a 
speirinu'U from Orizaba, INIexico, of l(!.o lines in length. There the union 
is about as extensive as in (Etlipm iiiorio. In the young of Tliorius 
peniuttttluN, the digits are not distinguished in specimens of .GO of the 
full size, and otherwise entirely mature. In the adult they are distinct 
for half their length. The digits in the young larva of Gyrinnphilus 
porphi/ritiruH are as distinct as in those of Spelerjtcs rubra. In one exam- 
l)le 1 find the simple foot of earlier stages retained, resembling exactly 
that of (Kdipus, excepting that there are emarginations for but three 
toes instead of five, (lenera which have no ])remaxillary fontanelle 
at maturity have it in the larval stage. Finally, closely allied genera, 
whi<!h only dilfer in the degrees of ossi/ication of the parietal and pala 
tine bones, represent simply the relation between undeveloped an<l 
developed conditions of the same form. 

The relations of the genera maybe expressed as follows: Those of 
the first or Plethodontine se(!tion are related to those of the second or 
Spelerpine by an incraet parallelism, excepting Autodax, whose pecul- 
iarities exclude it from the comparison. Those in ea(!h section differing 
in the union or separation of the premaxillary bones are ndated in 
the same way to each otiier. The nearly allied genera in the IMethodon- 
tine groui) are llernidaetylium and Plethodon, and liatrachoseps and 
St<'re()chilus. In the first case we have only inexact parallelism, because 
while Plethodon lias the four digits of llemida(!tylium, its parietal 
bones are unossified, tliough an acceleration of development in these 
respects would render the relations one of c.raef p((rallelis))i. This is 
apparently the relation between l>atrachosei)s and Stereochilus, Ww 
with the fcetal digits of the latter the former preserves also its fcetal 
cranium. It only renniins to ascertain whether Stereochilus loses its 
branchiae before or after aecpiiring the normal number of digits. From 
the very small size of one at least of these the fcn-nu'rcase seems pro!) 
able, but I have not yet been able to prove it by direct observation. 
Should it be so, we would have a <!ase of crnet jmrrt//f/j.v»i. 

In the Spelerpine group the relation between (leotriton and Gyri- 
uophilus is again one of inentet parailelism, since when the digits of 
the latter are only separated at the extremities, as in the former, the

liiini toes, as in .Miiiic.iiliis ; tlierefoio the n'lation of these two is also of 
inexact parallelism. The relation of Thorins is also one of iiicrart par- 
tillcli.siii, for thoMiiii its eliaractters are fonnd in some .voiui^" Sjx'lerpesat 
an immatjire a^ne snbseqnont to the absorption of the brancliiiu, it lias 
opisthocu'Ins vertebra'. With (Edipns, if the condition be not that of 
cvdcl iiiiniUfli.sui with some species of Spelerpes, the approach to it is 
close, as above observed. It is chiefly pi'cvented by the fact that the 
ossifK^ation of the parietal bones in most species of the latter takes 
place after the extremities are fnlly developed. It is to be ol>served in 
tliis connection that, as has been above pointe<l out, the separation of 
the (li<,'i(s takes j)lace at very dilferent periods in the history of the dill'er- 
<'iif species of the same ;;(Miiis. Thus in the Sjirlirjics nihcr {hoy are en-

Some other chanicters found in tlii.s tiu lily are those of low develop- 
ment nnd iiijproxiiniitions to the larvul condition. Thu.s three of the .spe- 
eie.s exhibit at tinie.s a subnareal cirrhn.s, which occurs in some of the 
Co'cilid! ', and Xenopus among Salientia. It is the persistence of that 
long sulDcular tentacle characteristic of the early larval stage of Uro- 
dehi generally (see Plate 10), and of a later larval stage of Xenopus 
(cid. Wyman and (Jray), where they resemble the appendages of the 
Siluridie. They have been called crochets by Itusconi, and homologized 
with the cylimlric cephalic processes of the larval liana, with what cor- 
rectness remains to be proven by ob.servations on other types. 

I'ischscholtz correctly rei>resents 7><(/ra(7/f>.st7).s' attcnuatiis i\>i without 
pretbntals. An elongate process of the frontal occupies only part of its 
place, forming no suture w ith the maxillary. This is (juite ditUirent from 
J)enK)gnathus, where the orbit is comi»leted by the union of frontal and 
maxillary. In ^fan(^nlus ijiiadi'idi(iit(itun the prefrontal occuipics this 
depression as an elongate vertical .scale. 

In fSpclerpcs ruber the (luadratum presents a small internal anterior 
ala, whi(;h has a superlicial resemblance to a pterygoid. In this species 
there is ai)parently an a/.ygus bone behind the luemaxillaries. This is, 
however, only the expo.sed extremity of their united spines, w hich are 
nearly or (piite i.solated by the approximation of thi^ anterior parts of 
the nasale. It does not occur in the Gyriuophilti.s porphyritkuti.

the (KiUinna laiijonitis KoR'i'st. of Contral America in its proportions. 
Its rehitioiis t;) the Jiatrocliosc/ni ultenuatus are close, but its dillerences 
may be siimniarized as Ibllows: (1) The two patches of paras[>ljenoi«l 
teeth; (li) tlie absence of dorsal grooves; (.{) tlie very elongate tail; 
(I) the longer pat<!hes of voiueiinc teeth. The habitat of the H. vnntl-

Tliis species is well cliaracteri/.ed by its slender form and its very 
weak extremities. The costal folds are nineteen, more rarely twenty or 
eighteen, and are well marked on the back and belly, and turned for- 
wards toward tlie median line on the former, which is marked by a 
delicate groove. There are tour latera\ folds in front of the fbie limb, 
three of wliicli are crossed by a longitiullnal fold from tiie orbit. The 
tail is longer than in any other North American salamander, except the 
/.'. candatit.s, and is entirely cylindrical, and undistinguishable at the 
origin from the Iiody ; it is marked by forty-seven distinct annuli to the 
end of the vent. The toes are very small and obtuse, and free for the 
length of only one plialange: below this a web connects them. The 
inner toe on both feet is a mere knttb. The extended fore limb reaches 
the transver.se Ibid behind the canthus oris; and the extended hind 
limb covers four intercostal spaces. 

The head is short, broad, and flat, and the muzzle is as long as the 
diameter of the orbit. The lip is more or less luominent below and be- 
Ibre the orbits. Tlie palatimj teeth do not extend to behind the nares; 
they form two very oblique short series, which nearly meet posteriorly

The color of the lower surface is brown, with a few whitish points on 
the },Milar reyion and tail, and fre(|uently over the whole abdomen. The 
sides are darker, sometimes almost black. The upper surface is <,'ener. 
ally a paler brown, with a lij^ht shade extending on each side from the 
nape to the base of the tail. These bauds arc composed of numerous 
short longitudinal streaks, which become separated on the base of the 
tail, and cover its surface to the end, or to the middle, as the ease nii»y 
be. This light color has generally a reddish hue, and in many speci- 
mens exteml entirely across the dorsal region, forming'a band, not un- 
like that of riethodon cincreus <ri/llir<mi>ti(s. 

Habitat. — Tliis is an abundant species of the Pacilic coast region of 
the continent, but it has not becui found to the eastward of the Coast 
Kange of mountains. I have ^^\aulined eight specimens from near iSan 
Francisco, in the ^Museum of the Philadelphia Academy, from William 
M. Gabb, and one in tlie iMnseum of the Essex Institute from the sauio 
locality, obtained by Mr. Samuels, and the following:

The last uanu'd, and probably P. (ilntinoNus, never enter the water, but

sloiKlorer aud more veniiitbrm, with much weaker le.i-.s than Rf/Iulinosus. 
Tims in .specimens of the two, measuring l.HO from snout to groin, the 
head and body of r.gUHinosu.s have the widtli onetliird greater. 

There are eighteen well-marked costal furrows between tiie limbs, 
excluding any in the axilla. The posterior are situated in +he groin, 
bifurcating above. In a single specimen of var. Cinereus (No. 3805) 
we reach a count of nineteen. This increase in the number of costal 
furrows is coincident with the wide separation of the limbs, the distance 
from head to axilla being contained about ^ times in that to the groin, 
instead of 2i, as in 1'. ghitinosus. The tail is longer than head and body ; 
sometimes considerably more so. 

This species, including all varieties, has an extensive range, being 
found throughout the United States east of the Mississippi JMver. It 
appears to be more abundant in the Middle States; its northern range 
is to the middle of Maine, Ontario, and Michigan. 

Its habits are entirely terrestrial, as it is never, even in the larval 
stage, found in the water. It is abundant under stones and logs in the 
forests everywhere, and does not occur in open llelds. The eggs are 
laid in a little package beneath a stone in a damp place. When the 
young emerge they are provided with branchia', but these soon vanish, 
and they are often found in this young stage apparently quite devel 
oped. 

ridhuhn vincrcus ciiurcu,, Green. 

The color of the upper half of body and tail is a dark liver-brown : 
beneath dirty whitish, linely vermiculated or mottled with brown in 
about e(|ual i)roportions, giving rise to a ''pepper and salt" appear- 
ance. There is sometimes a yellowish tinge towanls the head, and ii 
phunbeous under the tail. On the sides the appearance is more that 
of whitish specks in a dark ground. Sometimes the upper |>arts are 
clear brown, at others more or less varied with very minute spots of 
dull grayish-white. Sometimes the under parts are so much clouded with 
'..fown iis to ajtpear principally of this color, only faintly mottled with 
lighter (3805.) 

This species is easily distinguished from /'. f/liitinoHUfi by much slen. 
derer form, smaller limbs, more webbed digits, eighteen costal groov«'s 
stead of fourteen, vermiculated under parts, which have not the black in- 
ground, the absence of the appearance of i)ieces of lead foil on th(^ 
sides, etc. The limbs are very small and weak. The digits arc distinct, 
though sliort. The basal web extends rather farther forward tlian in 
i'. (/luiinosuif, the two terminal joints of the longest toes only being free, 
instead of two and a half. 

I can detect nothing in the characters of bead and tongue difl'ereut 
from /'. glutinosus.

I have been uiiiiUle to detect any tlilt'croneo in striictnre, proportions, 
and general character between tliis snppo.sed species and P. eincreus. 
The only diil'erencc, if any there be, is to be found in the color of the 
back, thatof tlie side and belly being very much the stmie. A broad, 
light-reddish stripe coininences at the nape of the width of the inter- 
orbital space, and continues to the tip of the t.iil, on which it dimin- 
ishes gradtiidly in width. The central region of this stripe generally

tlie body are abruptly and continnously dark brown, but soon fades oil' 
below into the pepper and salt of the lower sides and belly. There is 
sometin)es the etfect of a broad dark stripe on each side the red, but 
this is usually very illy delined below. 

The color of the red stripe varies considerably. Sometimes it has a

blance in size and character with the l're(iuent association in the same 
localities between the two species have given rise to the belief that tlu'y 
were ditJereut sexes of the same species. That this supposition is in- 
correct is i)roved by the fact that both males and females are found of 
each kiiul, as was long ago noticed by llaldeman. As varieties they 
are very permanent ones, as I have Ibund all the young of the same 
brootl or set of eggs, whether in the eggs or Just escaped from them, 
uniforndy with either dark backs or red ones. 1 have found adult red- 
backed specimens watching eggs with red-backed endiryos, and biowii 
backed in charge of brown-backed embryos. Tliere is also some dillci- 
euce in geographical distribution. Thus, on the west side of Laki; 
Champlain,in Essex County, New York', I'rol'essor Jiaird states that lu^ 
lias found the red-backed salamaiuler very common, and never saw there 
the r. cinercus. Among a very great numlterof specimens which I hav(^ 
examined iu the collections of tlie Smithsonian Institution, the A(!ad- 
emy of Natural Sciences, and Mssex Institute I have observed but four 
specimens of the red-banded variety and four of the gray which could 
be regarded as intermediate in cliaraiiter. This apjiears in a rufous 
cast in the dorsal color of the latter and a slight obliteration of the 
borders of the dorsal band in the former. Such coloration is, however, 
very uuconimou in the living animal, which is everywhere exceedingly 
abundant. The statement made by J. A. Allen that such are aliundant 
in Massachusetts is not conlirmed by the siiecimens iu the museum of 
the Essex Institute, ]\Iassaciiusetts. 
An examination of 



types 



indra (ifiilis (.'5770) 



shows them to belong to this subspecies. His variety with livid back 
is the ricthodoH cincreus cbiereus.

Cope, Tror. Ac. I'liila.. l.-(!!), p. 100 (niiine only). 

This snbspecios lias tlie sizciuul jjioportions of body ami limbs as in 
P. cryllironotitft, but may be readily dif^Miij-iiislied by the smaller number 
of costal furrows, shorter body, and (lillereiit character of the dorsal 
stripe. 

There are only sixteen costal furrows between tlie fore and hiiul legs, 
instead of eighteen, as in /*. rn/tlinniotus. This indicates a shorter body, 
and accordingly we lind that the distance from snout to armpit is con- 
tained only three times in that from snout to groin, instead of 3^ or ;M, 
as in tlie other. 

I am unable to detect any difference in the mouth, tongue, teeth, or 
limbs. 

In alcohol there is a broad yellowish red dorsal stripe, which begins 
Jit the uape and extends to the end of the tail. On the back it is otj an 
average as broad as the interorbital space of the head. The outlines, 
instead of being parallel or nearly so, are very irregular on the back, 
exhibiting tour or live coarse dentations between shoulders and rump, 
which in some specimens are nearly opposite each other (causing the 
dorsal stripe to be twice as wide at some places than in others), or more 
or less alternating. On the tail the outlines are straight, converging 
slightly to the tip. The sides and beneath are dull brownish-yellow or 
whitish, finely mottled, or vermiclated with dark reddish-brown, which 
becomes more crowded to the dorsal stripe, and is sharply relieved 
against it. 

There is a distinct light line from the upper eyelid, passing internally 
to the nostrils and meeting its fellow iu an angle in the middle of the 
muzzle, then sending down a single line to the edge of the lip.

TluH subspecios i.s iciidily distinguished IVoin P. erj/throHotus by tlui 
din'oient relative position of the linibs> .iJid uiimber of costal furrows 
already referred to. Tlic very jagged or irregular outlines of the dor- 
sal stripe, the light line on the nose, and the lighter and more reddish 
shade of the lateral and inferior mottling will at once distinguish it as 
far as color is concerned. Tlio duskj* shade of the sides is not continuous 
above, but shows distinctly minute mottling of lighter. 

It is somewhat dillicult to assign to this form a definite status. I 
should be disposed to regard it as a good species, but for the fact that 
out of a great number of specimens of the i'. crythrnnotus var. cinercm 
1 lind a single individual (Sm. No. 382.")) from Ohio which presents the 
proportions of the present species, and the same number (sixteen) of 
costal plicas For the present therefore I refer itas a subspecies. I have 
seen live specimens, which agree in every particular ; one in the Museum 
of the Kssex Institute in a bottle with the common varieties of the P. 
crythronotm, the Spclerjics hilincatns, and Desmognathus, all from Es-

Habits. — The Pkthodon cinorns is the most abundant salamander in 
the northern and central eastern United States. It is of terrestrial 
habits, and is easily found under logs and their bark, stones, etc. It 
feetls, like other species, on insects and their larva', cai)turing them by 
applying to their surface its Hat and projectile tongne and jerking 
them (juickly into its mouth. It frequently climbs to the summit of 
low vegetation, from which it springs by a sudden straightening or 
curvature of the body, as the case may be, in the manner of a cater- 
pillar.

iiiid loiigcf than the body. 
Theskin is evorywiicre closely lined with short perpendicular slnnds for 

secreting a milky jiiico. Tliese are largest on the upper surface of the 
tail and more scattered on Wh'. belly. The skin is also closely covered 
with shallow pits. visii)le only when the mucus is removed and through 
a lens. I have not observed any large pores in patches on the head. 

The head is broad, the sides i)arallel to the eyes, then converging and 
distinctly truncated at the cn<l. The eyes are largo and i)ronnnent, 
separated anteriorly by one and one-half diameters of orbit ; the »lis- 
tance to the nostrils and between them rather less than this amount. 
The nostrils are lateral near the end of the muzzle. The upper jaw 
overlaps the underconsiderably, especially anteriorly; where there is a 
slight protuberance downwards of the lip on each side, the n.uzzle giving 
a concave out'line when viewed both from before and laterally. There 
is a slight groove down the side of the muzzle from the outer edge of 
the nostrils to the swollen part of the lip. 

The gular fold is entirely adnate, without any overlapping. 

There are fourteen well-marked costal furrows, including tiie inguinal 
and one close to the forelegs. They are distinct <mi thesides, but inter, 
rupted on the back and belly; none are distinctly visible along the 
pelvic region and the tail. There is a shallow fuirow along the back, 
but not the least sign of ridge or compression on the cylindro-quadrate 
tail, although this is rather higher than wide towards the end. 

The limbs are moderately developed. The digits are short, broad, 
linear, cylindrical, depressed, and slightly swollen into knobs at the ends, 
where they expand very little, but without any appearance of a disk. 
There is a short, thickened membrane connecting the basal joints of the 
digits, leaving three phalanges free of the longer toes and two and one- 
half of the lingers. This inend)rane has the etfe(!t to cause tlio bases of 
the digits to stand out very free and separate from each other. 

The second aiid third lingers are nearly e(pial, the latter rather longer; 
the third toe longest; the fourth sometimes not shorter. The first 
linger and toe are quite rudinuMitary, being a mere knob. The distance 
from snout to axilla is contained less than three times in that to groin. 

The tongue is very large, in alcoholic speiumens frequently l)rotnid- 
ing beyond the Jaws all round. It is oval, longer than broad, lleshy, 
and highly papillose, thin towards the margins. It is very slightly 
emarginate behind, the notch bordered by a ridge on each side. It is 
l)edicellate, free behind and on the sides, but ailixed to it anteriorly; 
the point of adhesion visibl" externally, as a circular or lozenge-shaped 
whitish spot just behind the jaw-bone, and about as large as the orbit 
of the eye. The attachment is comi)lete anterior to tlie pedicel, which 
again is free from its sheath only behind. Tlie tongue is thus evertile 
and capabh of being thrown outwards. There is no free sjrace anterior 
to the pedicel.

This species in alcohol is of a livid bluish black. The upper parts 
and sides are nuukcd with well-detiued specks of a grayish-silvery 
color, looking like torn i)ie(!es of foil. These vary with the specimen, 
but are generally more numerous and larger along the sides. The 
under parts are sometimes tinely dotted with whitish, but this isusually 
the effect of the whitish glands seen through the integument. The 
under i»art of the tail is of a pale bluish-gray. The light spot on the 
chin, showing the attachment of the tongue, has already been referred 
to. The soles of the feet are also whitish. 

The back is sometimes destitute of spots, or they are very minute 
and these when present are often duller than those on the sides. There 
is occ^asioiialiy a yellowish tinge in the lateral spots- A few sjiots of 
the same kind are sometimes found under the chin. 

Young si»ecimens are marked like the adult, except in being whitish 
beneath, and in freciuently having the white spots more i)uuctifornx 
and s(!attered. 

A number of young of eighteen lines in length from caves in Mont- 
gomery County, Va., have ii series of small bright red spots on 
each side; some others from the same locality do not exhibit them. 
The variation is thus remotely similar to that in IhsmoifHathus/KNca. 

I have not been able to discover any permanent dilference between 
the southern specimens of this species and the northern. I have 
thought tliere was a greater tendency to expansion of the light spots ou 
the side, so as even to form a continuous band, and to a reduction in 
size or disapi)earance of those on the back. I have, however, Ibuud

si)eciiiieii.s of precisely similar chanictor iVom iiortheni localities. Some 
soutlu'iii speciiiieiia appeared to liiive tlie ai;;its less webbed than usual. 
Ill certain 8i)ecimena from Sontli Carolina described by llallowell the 
white sitots fail to exhibit themselves on the sides, the color being 
everywhere a deep black, the gular region, lips, palms, and soles being 
of a clear yellowish-brown. This (^institutes a well marked color vari- 
ety, but no ditierences of a higher value can bo found. There are four 
specimens of it in the iMusenm of the J'hiladelphia Academy. 

The range of this species is from Texas to Maine. It is recorded by 
Packard as from Okok, Labrador (.Mem. I'.oston Soc. Nat. Hist., 1808), 
but I suspect that this animal will be found to be the Amhly-stomu 
jefcrsonianum var. lateralc, which has, with the .1. ,;. platincum, the 
highest northern lange. It appears to bo common in Massachusetts 

and Maine. 

This salamander is entirely terrestrial in its habits. It is found much 
more abundantly in the mountainous districts, and haunts rocky locali- 
ties as well as Ibre.st mold and fallen logs. 1 have found it mote 
abundant in Tennsylvania and New York than in southwest Virginia. 
1 believe that it prefers a cool climate; in the Hat and warmer tertiary 
and cretaceous eastern coast region it is rare. In southern Pennsyl- 
vania I have only Ibund it on the northern exposure of the south Ches- 
ter Valley hill, never on the southern exposure or other part of the, 
north hill. In southwest Virginia it is more common in caves than on 
the surface.

The coloration is peculiar. Instead of the black color, with or with- 
out ])ale bluish dots, of tiie /'. fjUifutomiN, the sides and back arc thickly 
spotted with large yellowisli-grecn blotches of irregular form, produc- 
ing an etfect something like tlie coloration of the ."Mexican Spclcrjxs lep- 
roNUS. The dorsal spots are much larger than the lateral, and are often 
continent. On the head they almost exclude the ground color. The 
s[)ots on the sides are (juite small, as are tho.se on the feet. The lower 
sides of the tail ami belly are dusted with yellow, and the throat is also 
dusted, and a little more coansely than the belly. 

The characters which distinguish the.se species from the 1\ glutinosus 
are theditlerent torm of the vonuM'oi»alatine series of teeth, the ab.sence 
of a costal dermal fold, and the coloration. There is some reseiublanco

This species may be readily known by its relatively short and slender 
tail, its lono;, weU-develo[)ed liinl)s, and wide head, as well as by il.> 
delicate coloration. 

The form of the body is rather depresse<l, with distinct head and tail. 
The width of the head enters the lenj^th to the j;roin in the larj^est in 
dividuals ~>.'SS times; in th().se of medium size, 4.a times; in the youii},' 
of 17.") lines in length it enteis ;i.."» times. Costal folds II, the an 
terior indistinct or wanting, the po.sterior nunx! than usually obliiiue, the 
inguinal extending forwaids and upwards one si)ace in advance «»f the 
originof the femur. The limbs appre.s.setl overlap, sothat the lingers reach 
the bases of the tot^s. There is no vertebral groove. The tail is slightly 
compressed, more distinctly so towards the extremity, and, what is excep- 
tional and (!liar;i(;teristic of this spe(!ies and the /'. rroaatcr, most so in- 
ferioily, leaving the nppi'r outline Hat for the pr(»ximal two-thirds the 
length. The postorlntal fold is well marked and (Mtntinnes into the 
traiisver.se fold of the tliroat. The head is oval, and without <!anthns 
rostialis; the mn/./.U\ rather thick, and with a suinnfeiior truncation, 
which is not so imirked as in J\ cnx-ntter. The. nostril is terminal and 
nearer the orbit than the diameter of the ey»' li.ssnre. The latter enters 
the width between the anteiior (ianthi of the smne !..'?.'{ times. 

The inner nares are very small. The voineriu(^ arcs curve backwards

medially, and iioarly or (luite in contact. Tho i)t<,Mygoi(l patcbes com- 
mence at some distance behind these. They are of usual breadth, but 
diver^ife more posteriorly than in the species of the lirst section of the 
jrenus, resembling thus many species of Spelerpes. Tlie teeth are very 
minute, and are arranged in series directed backwards and inwards. 
The tongne is a little more free than in P. ffbitinnsus, as the lamina 
connecting the anterior and nie<lian points of support is «piite thin. 

The inner toe in both i)air of limbs is (juite snuill, but free and better 
developed than in P. f/lutlnofim. In the anterior i)air the third is the 
longest; the second is a little shorter than the latter, aiul the fourth a 
little longer than the lirst or inner one. The longest toe in the poste- 
rior limbs is the third likewise, the fourth being nearly equal to it, 
whilst the second is a little longer than the fourth, which itself is a 
little more develoju'd than the lirst or innermost. Phalanges 1-2-3-2; 
l_2_;{-3-2. 

The skin is perfectly smooth externally, but on being examined under 
the microscope it exhibits a nuvsh-work of little stellated mucous pores, 
similar to those of Auto(1a,v liignbi-is, but proi)ortion!illy larger. 

According to a sketcth from life made by Mr. Drayton, of the United 
States l"^\pl()ring I"]xpedition, the ground color is milky white, with 
crowded dots of reddish brown. On the si)ecimens preserved in alcohol, 
however, the b()dy, head, and limbs are of a unifornj dark brown, lighter 
beneath. Under a low magnifying power minute dots may be observed 
vsciittered all over the surface. The <rolor would appear to vary sonte- 
what. A drawing in the Smithsonian re<!ords, <'()Iored fnun life by 
Samnels, represents the sides of head and body with lower snrface of 
t.iil and anterior faces of limbs of a bright orange. This is the color of 
living specimens which I have tak» i myself.

pressed and narrowed in seiitiou below. No prominent glandular ag- 
glomerations or pores. Only three jdialanges in the fourth toe. 

Form of head peculiar. It is very broad, with straight converging 
maxillary outlines and truncate muzzle; upper surface nuich narrowed 
on nuizzle; loreal regions plane, very oblique; canthus rostralis not 
miirked. Maxillary outline oblicpiely spread at and behind orbits, 
where it is exceeded by the projecting margin of the mandible. Ante- 
riorly, and at the end of the nui/.zle, it [>roje(!ts considerably beyon<l man- 
dible. Muzzle truncate in i>rohU^; a slight euiarginaticni at middle of 
premaxillary Ixu'der, and a groove on vm'.U side of it on inferior pro- 
jecting ftice of lip. Nares terminal, some distance above the angulatioii 
of the lii>, continued below in a groove, which bifurcates near lip mar- 
gin ; the posterior line exti'iiding a short distance, the anterior to the 
median ennirgination separating the anterior from the inferi.n* plane of 
the muzzle. Kyo. large, not very prominent; its anterior canthus well 
in front of ndddle of Jaw, and 8e|)arated one diameter from nostril and 
1.5 from the other eye. 

No f'^ld acaoss front angle to angle of mandible, but the gular, pnro- 
toid, and postoibital grooves well marked. Costal grooves indistinct; 
!.'{. Skin everywhere very smootii. 

Tail longer than head and body by the length of the mouth. Width 
at (Mirves of niiiiidible 4.0 times in length to groin. Extremities slen- 
der and long; when pressed to the si<les the lingers extend to the heel. 
Length of wliole fore lind» 2.7-j times in length to groin. Inner tinger 
very sunill, half the length of the fourth; third longer than second. 
Sole narrow ; longer than longest toes. Inner toe less than half the 
tifth; third a tritl(> longer thiin fourth; s(>cond much longer than tiftii. 
Lower leg .7"» thigh to groin. 

Patches of parasphenoiibd teeth, two in conta<^t anteriorly, well 
separated front palatines. All the teeth minute, mnnerous, acute 
cylindro c(uii«'. Tongue with ratlu'r straight lateral and posterior out- 
lines. 

(\)1(M' tlu'oughout pitchy itbick, fading into bright red orange below ; 
limbs orange, a blackish cross baiul below tlie knee. A large red- 
orange si»ot on «>acli paroroid region, and tbursniiiller, irregular, similar 
spots on the body to base of tail on each side of and near the vertebral 
line. A pair of orange spots at base of tail and a distant seiies on the 
upper face of the tail. 

Ilesides the type, a specimen of this species was obtained at Cape St. 
Lucas, in Lower CaIiforui;», and I have seen om^ from near San Diego, at 
the northern end of that peninsula. As the typical specimen was 
ifouiid at Fort Tejon, Cal., the range (»f the species is extensive.

eye. Both iii)per and lower pali»ebiie are transparent, a feature pecu. 
liar to til is species. 

Tlie pores of tiie skin are large and on all the upper surfaces closely 
placod ; on the sides more distantly. The mucous p(U'es on the head are 
distinct and larjie. They form a douhle seri«is along the canthus ros- 
tralis, ami a snigle one ahove the orhir, which turns round the latter be- 
hind, and is conf'inued b'dow it and along the side of the muzzle to the 
nostril. A series of similar large i)ores extends along the middle of each 
side, one a little in front of the median point of the intercostal spaces. 
Tiie tail is compressed fnun the base, and not elevated ; it carries a strong 
free dermal border along the median line aboveon the distal two thirds; 
a narrower dermal margin exists on the inferior distal half. The limbs 
are short and weak, but the digits are well developed. The posterior 
extended forwards measures If) intercostal intervals; the anterior 
measures backwards 4i of the same, counting the axillar. The jdia- 
langes nuMd)er on the posterior feet \-2-',i-',i-2; on the anterior, 1-2-3-2; 
the terminals are (piite acuminate, especially behind, where in one indi- 
vidual they have a slightly corneous sheath. Tiiere are 17 costal folds 
and an axillar space. The tail is not annulate. 

The rictus of the mouth measures nearly the diameter of the eye 
behind it. The tongue issmall and free all round, cxceptat the anterior 
margin and along the median line to the glossohyal pedicel. The 
vomeiine teeth exteiul behind the nares in two series, which are con- 
vex posteriorly; they approach each other as though at an angle 
directed anteriorly, and then suddenly curve backwards and form the 
pterygoid series. These are more slender and more nearly approxi- 
mated than in any other species, and consist ea(!h of but one row of 
teeih to th(^ point where they begin to diverge; /. c, near the posterior 
|)art of th(^ globe of the eye. They do not diverge widely and exhibit 
but a few scries of teeth.

The color is a deli(Mte yellowish-brown, with numerous brown lines 
interspersed, which form several dark bands along the side. A nar-

yellow line, brown-bonlered above and below, extends from axilla to 
groin. The tail, belly, and gnlar region are closely brown-8i)ecked; 
similar specks occur on the sides of the hea<l behind. The ground color

identi(!al in its osteoloojical (iharacfi'rs with the jjonus Neeturns, except 
in the absence of the intercilary bone, and tho number of posterior

The lower edoe of the upper jaw viewed from before is (loiicave, being 
bounded on ea<di side by the rid^e Just mentioned. Tlu're is no well- 
delined cirrus however. The side view of the lower ed.i!;e of the upper 
jaw is also con<'ave. The upper Jaw pr»»jects larj;ely over the lower, 
most so anteriorly. 

The eyes are lar};'eand prominent, distant anteriorly about «)ne and a 
half len^-lhs of the orl>it ; the external nostrils one orbit len.iilh apart; 
the inner less than this. The latter are very minute. Tiie touffuo is 
circular, entirely (ree, pedicellate, and j^n'atly protractile. 

Theteelh are much as in Sprlcrpr.s riihrr; tho. parasphenoidal bauds 
perhaps rather narrow. 

The body is rather vermiform, beinj;' of equal si/,(^ throu*;ho(it, uuich 
depres.scd, with a furrow fiom nap«' to above anus, where the tail risi ; 
into a sharp rid^f, which continues to I he tip. There are sixteen distinct

costal fiiiTows, oxd^l(lin^' an axillary oiic, and livo pelvic. Similar fur- 
rows ran In- traced to the tip of the tail. Tlie tail is (juadrate at the 
base, with ronnded anj-les, broailer than hi-;'!!, but becomes more and 
more compressed to the tip. The limbs are feeble and widely separated. 
The di^'its all distinct, but small ; the lirst rather riidinicntary. 

In alcohol mature individuals of smaller size are of a lij;hl brownish- 
red on the baitU, the sides and itenealh pile reddish salmon t'olor. The 
sides of body and tail, however, and to a less extent the back, are closely 
covered by a coarse, indistinct reti(!uIation or network ol" rather dark 
brown, showinj? the li;.jliter -iionnd color in tlu^ areola', and <!onvcyin<,' 
the impression of rathei- oblon.i- lij;hl spots. Tlie under parts are 
jjenerally immaculate, tliou.;;h larjic spiMtimens are sometimes fiindy 
sprinkled with dusky. There is always a li<;ht line from the eye alonj^- 
the can thus to thecdj-e of t!ie upper Jaw; those of opposite sides parallel. 
With iiicreasin;;' aji'e liie icticulation of the. sides be(!onu's obscured 
by theextension of the ^rouml color of tlu^ i)a('k over the sides and Jie 
•fading (tut of tlu! dark markinjjs. Tlier<' is, however, j,M>nerally a dull 
(iloudiuH' (»f darker and a. faint indiiiation (»f the light spots, especially 
on the lower part of the sides. 

This species dilfers from tSiKlrrpiH nihcr in many details of external 
fiU'iii — the more vermifoiin and depresse<l body; inoi'e widely separateil 
fore and hind legs; oiu> more costal furrctw ; the more depressed, nu)r(^ 
truncate, and broader head; larger eyes; prominent ridge iVoin eye eon- 
tinned to margin of upper Jaw. etc., not to nuMition the diU'creniie in 
coloration. To S. r. Jhirissiiii lis it is related l»y the |Motuberan(U's on 
the upper jaw on each side the muzzle, iuit these are less pi-onnnent. The 
tifteen costal groovesandsiiai'ply detined idaek sp(»ts without reticulation 
on the sides distinguish the former. 

A specimen from (Icoigia (I7l(i) dilfers in a more slender shape, and 
in having dark, horny tips to the digits, as in tli<' afpiatic Audilystonue, 
as if having lived in a drier region than usual. 'I'herc are only lifteen 
costal grooves to be distinguished.

Tliis i.s a natural ^cnu.s, and i.s abundantly represented by individ- 
nal.s in the eastern di.stiiet of the nearetie realm, and the Mexican of 
the neotropie.tl. Its di;;ital characters oidy distinsnish it from !\raii- 
eidns, and some of the .Mexican species approach that genus in the 
great reduction of the inner digit, which ri'snlts from a diminution in 
the nundter of phalanges. The cdiisolidation of the premaxillarie.s — a 
marked t'liaracter — appears very early in the developmental history of 
such of the species as I hav*' i)een able to study {S. niba; S. bilincatus). 
The .Mexican siiecies pass their me(amori>ho.ses soonest; then such us 
S. hilin(atii.s, and the S. ruber remains longest a larva. 

The characte.s of lune species of Spelerpes are given in the follow- 
ing table. 1 know of none otliers, tliinUing that the genera (Ediims, 
(I'Mipina, and (leotriton should l»e maintained as distinct. Of these 
species four only inhabit the ju'arc^tic realm, and five are found in the 
Tieira Teinplada of Mexico, on the eastern .side of the plateau. The 
nearcti(! specii s are all conlined to the ei'.steru region, the genus differ- 
ing in its range from IMethodon in not extending to the Pacific region. 

The largest species of the Spelerpes is the S. bcUii of Mexico, which 
among salaman 'ers is only exceeded in dimensions by the Ckonilrotiis

In desciibinj,' this species I have selected specimens IVoni New Jersey 
as inostliivc the type of Dr. (Jreeii from the same State. These are 
before nie, but are in rather indilVerent preservation. 

The general characters of the gronp as described under ^'. huyicauda 
apply equally here. The chief differences of form appear (o consist in 
SI rather narrower head, a more elongate body, and perhaps i»ropor- 
tionally more slender digits. There are usually fourteen costal furrows 
between the limbs; a lifteentli falling over the in.sertion of the forelegs, 
and in some specimens possibly in the axilla. The distance from snout 
to axilla is contained about 2n times in that to the groin. 

There is only a slight obtuseness of the lip on each side of the muzzle 
to represent the cirrous ai)pendage of the larva, which is sometimes 
persistent, thus presenting the characters of the suppo.sed species tS. 
eirriijcra. 

This s])ecies is of a clear yellow; the back with a tinge of brown on 
it, and this bordered on each side by ;i dark-brown line; sometimes 
very continuous, sometimes slightly broken here and there, beginning 
at the eye ; sometimes at the muzzle and running through the eye. 

The space between the lines is finely spriidiled with brown or black, 
sometimes only appreciable under a lens, sometimes more distinct. In 
most specimens the larger spots are aggregated into a narrow nie«lian 
or dorsal scries extending to the tail; the spots on the line sometimes 
partially or entirely continent. The under parts are always entirely 
immaculate citron yellow. The sides aie very minutely dotted with 
blackish below the lateral stripe; in nearly all the si>ecimens from 
Orange only distinguishable under the lens, and impaiting a slight 
dusky shade. The amount of dotting here on the side is scarcely 
greater than that on the back. 

'ii perhaps the greater nund>erof specimens the mottling of the sides 
is „reater than as described, making a broad lateial band, .sometimes 
fading giadnally out of the dorsal surface, ami fading out along the 
belly, sometimes leaving the lower edge of the dorsal stripe well 
marked; occasiomdiy the whole sides are almost as dark as the lateral 
stripe. There is a row of pores on the upper part of the sides, one to 
each intersitace between the costal furrows. The.se show in the «lusky 
sides as a line of whitish spots, as tliey «lo in *S'. (jutlolincnta. This may 
be owing in both either to the transparency of the epider«nis or to the 
actual presence of spots of white around these pores. 

This species bears a cIo.se resemblancse to ncsm<>(fn<Ulius orlnophaa in 
some of its conditions of coloration. Tiie latter may be always «lis- 
tinguished independently of the generic characters, by the broad light,

on the belly. 

In the large series of specimens before mo are some specimens (4735) 
from the vicinity of Lake Oqnassa, which ajipear distinct from any 
others in the collection. They have more the general appearance of 
Desmognathns, though truly Spelerpes. The muzzle is rather longer 
and considerably higher at the end; the protuberance of the lip on the 
side of muzzle larger. The side of the head anterior to the eyes is 
much pitted with pores, scarcely appreciable in the others. The colors 
are darker; the dorsal stripe browner; and the mottling of the sides en- 
croaches on the belly. The chin is quite consi)icuously mottled. Tiiese 
<liirerent;es mark a variety which Baird reconls in his MS. under the 
name of /S'. h. borealis. 

A few specimens have but thirteen costal folds, and one from Georgia 
(4737) has that number on one side and fourteen on the other. Those with 
the fewer plic;e have usually shorter bodies. This is particularly the 
case with three specimens (374S) from (leorgia, where the width of the 
head enters the length to the groin but little over five times. The sides 
are in this variety dusky, with a series of white puncta below the lat- 
eral band. The dorsiil region and top of the head are abundantly punc- 
tate; sides of tail uniform black; belly immaculate. This variety con- 
nects with the S. bilinvnt<i,\\ni Sahxmnndracirrifiet'a of Green. The fol- 
lowing description is taken from Green's type in the Museum of the 
Smithsonian Institution (No. 4743). 

The head is depressed and anterior to the eyes. The sides, instead 
of tapering to a truncated muzzle, are nearly parallel to the truncate but 
rounded muzzle. This squareness is produced by the development of 
the protuberances of the upper lips on each side the muzzle, which, al- 
though partially indicated in other species, here attain their maximum 
of growth, becoming cirri, which are cylindrical and a little knobbed 
at the ends, extending downwards past the lower jaw. They are about 
as long as the outer linger, or .05 of an inch in length. The appearance 
presentiMl is not uidike that of tlie muzzle of a walrus or morse. The 
narrow groove extending from the outer edge of the external nares 
passes all the way down the antero «'xternal surface of the cirri. 

There are but thirteen costal grooves, including an indistinct one in the 
groin. A fourteenth, if present, would fall above the insertion of the 
fore leg. The «listan(!e from muzzle to axilla is contained oidy about 
two and a half tinu>s in that to the groin. 

The tail, as in other species, is slender and compressed, longer than 
the rest of the animal. 

The digits an; unusually long and very slender, considerably longer 
than in var. S. h. hilini'dtiis. Tlu' limbs are also well developed. 

Tliecohu' is \\\\u:\i the same as in s. h. hiliticatns — yellowish, with a well, 
detlned line of bla(;k on each side the back, tlu; intermediate si)ace

Althon^di tlie form wiiidi presents this sin^^idar eliaraeter is not typ- 
ical of the species, 1 do not consider it to lie referable to any other. 

IJesides the original two specimens of (Ireeii, I have seen threeothers 
bearinff cirri, which 1 took with two noncirrigerous ones on the slope of 
tlie IMack Mountiiins of Nortli Carolina. These specimens are otherwise 
of typicid ciiaracter. 

Tlie cirrus is a larval character retained, which, were it peinianenr, 
wouhl be of ;>eneric value; but it is not so, and in this case an individ- 
ual feature only. The same peculiarity I have observe<l in two speci- 
men; of S. chirnplcrKs sent by Sumichrast from Mexico, and in speei- 
nuMis of S. lotiijicnwUis and S. (jiiltolinv(itiis I'roni the I'nited States. 
The other charai^ters of this variety, thonjih marked, are nn)ddied in 
various intermediate dejjrees in individuals from various, especially 
southern, localities. The form of the tail is Just as in the typii-al variety, 
though Ilolbrook has stat«-d them to diller. 

This species is very al)undant in Tennsylvania, and exteinls its range^ 
with decreasing nund)ers, to iMaine. It differs in its habits from the 
.V. Umgicnndus in being to a great extent a water animal, and less fre- 
quently found under bark and stones. It is oidy in shallow, stony 
brooks that it occurs, however, and ciin not be called a<piatic in the 
serse in which the Tritons are. It is very active, and wriggles and 
runs from the jiursuer in thesanienninner as, and generally in company 
with, the Ih'smognathm fiisca. It is one of those species whose meta- 
morphoses arc prolonged and which remains in the larval state until 
nearly grown. 

This species appears to be the one to which must be referred the

This .species i.s .sU'iKlt'r and i'loii};ato(l; (lie head llalteiied and iiiiudi 
depressed; the body depies.sed; the tail compressed troni the hase, and 
considerably loii{;er than the rest of the animal. 

The surface of the skin, thoii^di smooth, shows everywhere shallow 
pits under the niicro.scope, and closely a;;<;lomeratcd granules, the ends 
of glands, which probably secrete a milky Juice. 1 have not made out 
any satisfactory indications of itatclies of pores on (op of the head, 
althoiijjh (hen^ are .some on the chin. 

The head is liattened, tlioii;;li not wedj;e-sliaped, qiiile jdaiie above, and 
twice as wide as dee]). It is longer (liaii wide, the n|»i>er Jaw overlapping 
the lower, especially anteriorly; the ninz/le is triangular, broadly trim,

begin ashort distance bohind their termination (witii a decided interval, 
ho\V(r\er), and lorni in patdies, in contact aloii<j the median line. 

The body is eh)n;,'ated, the distance from snout to axillacontaincd L'ij 
times in that to the groin. There arc twelve lateral costal grooves; the 
posterior biliir(!ated above and anterior to the groin. I C the fin row here 
be counted there would be thirteen grooves. The anterior is one inter- 
s])aee distant from the axilla. 

The tail is very long, generally \\ times longer than the rest of the 
animal. It is much compressed from the base to the much-attenuated 
tip, but IS nowhere as high as the body. 

Tiie liud)s are nui(;h developed; the digits lengthened, narrow, linear, 
cylindrical, tlepressed, and swollen slightly into bulbs at the ends. 
There is no basal connecrting membraiu'. The third and fourth toes are 
longest, the latter perha|>s longer of the two; the second and lifth are 
nearly ecpial. Tin? first linger and toe arc very short, though not rudi- 
mentary.

The ground color of this species is of a clear bright yellow, paler bc- 
iH'atii, the ba<!k an«l sides irregidarly spiiidded with black specrks look- 
ing like grains of rather coarse gun|)()wder. These are generally (but 
not always) more lliickly crowded along the sides, sonu'times almost 
forming a distinct spotted band on the sides of the tail; these black 
si)ots are generally aggregated into a series of vertical baiuls. In 
younger sjK'cimens, an<l many older ones, the sjwts above are arranged 
in three rather irregular lim's, one me<lian and two lateral larger ones. 
TIh' muzzle and entire under parts are immactulate. 

In old individuals there is sonu'times a suHuslon of reddish-brown 
among tlu', spots on the sides, obsc-nring their outlines. The shade of 
yellow varies sometimes to a reddish tinge. Sometimes the black s^iots 
on the siib's are arranged in a Komewhat reticulated manner. 

This beautil!!! animal is not very active in its habits, and is almost 
always found h\ rocky ground ami in lissures and caves in clitl's. I 
have lu'ver seen it in the water. It was di'scribed by Katlnesipie from 
a specimen from a cavern in Kentucky. Its distribution is thnuighout 
the middle latitudes, rather rei>resenting the IS. ynttoUneatus of the far 
Scmthern States. 

1 have recorded a specinu'ii of this speciies from Tennessee (Anierican 
Naturalist, IS71, p. KM), in which the b;dancers were persistent, as in 
the cirrigera form of ISi>dcrpvs hilin(ahi.s.

This si)ecio.s in its gouoral proportions, sliiipc, vlv., is vriy similar to

is (lividtMl (H'liti'iill.v l).v a loii^Mtuiliiial ilark lirowii line, b('<;iiiniti<; as a 
few (luts, oil the t(ii> of tlu> licai], tlit-ii uniting; into a (Mtntiiiiioiis stripe, 
which vxtciids to the riitni>, and is a littk; iiairower than, or about e(|iial 
to, the two li}>ht stiipos into wliich it diviihs tliu color of the back. 
Tim lij^ht dorsal stripe is bordered on each side by a continuous dark 
stripe well delined on the upper ed}je. The under parts are .vellowisli 
in alcohol, distinctly mottled or veriiiiculated with brown in about 
e(|ual proportions. In tlu^ present specimen there is no distinct li^ht 
line below the brown of the sides, which breaks up gradually below, 
passiii}^ into the reticulation described. There is a sinjjle light spot in 
the darkest part of the sides, one to each intercostal section. The sides 
of the tail are dark brown, with vertical light bars analogous with the 
white spots just described. 

In other spe«'iniens the dark brown which bonlers the yellowish of 
tli(^ back is sharply defituMi on its lower margin, also forming a con- 
tinuous line of variable diameter, with a series of white spots, one to 
eacth space, between tli(> costal furrows. ISelow this iigaiii is another 
contimious, quite well-delined light stripe, after which succeeds the 
inottling descriiietl. In this casii then' are three black stripes, om> 
median dorsal, and two lateral; and four light stri|u>s, two mtMlJan,of a 
brownish-yellow color, and two lateral, whitish in alcohol. 

The comparison of form has already been made with «S'. loiifiictiuthis. 
The color dilfers essentially in tlic vi'riiiiciilation, with l»rown beneath, 
instead of being p«'rfec(ly immaculate. If the varieties ofN. Iinii/icainhtu 
having Ihrei^ series <»f (basal dots hail these united iut«» eonliniiouH 
stripes there would W some resemblamu' to the present species. Such 
is, however, never the case. The tail, instead of being yellow, with 
narrow vertical dark lines, is dark, witli narrow verti«!al light ones. 

1 have found a cirrigerous form of this species in North Carolina.

The form of this species vaiies with its age, the v<'ry old ones being 
neaily as stont as Amhiistomn itinicttiliim ; more so than A.opacKm. The 
more immature, however, are rather slender. 

The skin is perfe<!tly smooth and lustrous. There are noindicatiouH of 
glands .secreting a milky Juice, as in Amblystoma, but the skin is every- 
wliere beset with shallow ])its, clo.sely set. The eyt^ is »'ncir(ded by a 
.series of pores. These extend anterior to those on the side of the head 
to the nostrils, and are nuire crowded. The lower edge of tlio lower 
jaw is encircled by a single seiie , <»f j)ores, and there are two other 
series, nearly straight, which start, from the point of the chin and diverge 
backwards.

Tlio lioatl JH (U'pn'ssnl, triiuiRulur, iiliiiost \v«'(Ij,m' slinpcd viewed hit- 
orally, ami rather pointed; more triiiieate in llieyoiin;;'. The iippi'ijaw 
is |>r(»jeetin}( and overhips th«^ h)\ver. Tliejjape isal»nnt .strai;,dit. Th*- 
end ol' the iipiterjaw is llatlened oliliqnel.v a little, visilde oiilv IVoni lie- 
low. The nostrils aie very saiall, placed more laterally than snperioily, 
andalittlu below the anterior end ol the ronnded eanthiis lostralis. 
Theey«'sarc directed antero laterally, so that the lines of the upper eye- 
lids would intersect before leachinj; the lip of the nose. 

There is oidy a sli<>ht constriction at the neck, the entire animal from 
head to rump hviu^ nearly of the same diameter, and the body passes 
insensibly into the tail. This is ipiadrate or nearly stpiai'e at the base 
(with riMinded corners), but becomes more and more compressed to the 
pointed tip. The dorsal surface of llu^ tail rises into an acute rid;;(> for 
the posterior twothiids, the ventral for one-third. There are liftcen 
costal ;;roovcs, including one in th(>. ;4:i'(>ii>. If cdiitiuned to the axilla 
there would be sixteen, but theic is no distinct axillary one. The verti- 
cal ;^roove.Hof the tail are distinct at the base of the tail, but so«»n bectome 
indistinct. 

A.S stated, old specimens havu a prop(U'tioiially larger body than 
yoiin;;c'r. 

The lindts are all very weak ; the dibits feeble. The third linj-er is 
lou^M'st, then the .second, fourth, and first. The third and fourth toes 
are nearly equal, then the second. The first dibits an* (piite rudiment- 
ary, especially the first toe. The youiijicr spei'imeiis appear to hav(* 
proportionally lonj^er diyits and more slender liiiib>. 

The toii;;iu^ is a nearly circular disk, entirely free, supportc'd on a 
slemler pedicel like a mushroom, and capable of beiiijn <'xtended beyond 
the mouth. The palatine teeth are transverse. Just beliiml the nostrils 
(by one diameter), and form an abrupt rectan;;le with each of the .series 
oil the parasphenoid bone, which widen behind and leave a free chan- 
nel down the median line. This free space ant«'iiorly is as wide as the 
diameter of the inner nares, but like the patches ol' teeth widens a lit- 
tle behind. The space is encroached upon by the plates of parasphe- 
noid teeth with aj;e. 

The inner nostrils are minute, about transversely elleptical and con- 
tinuous, with a well-delined narrow -groove runninjiout to the maryiii 
of the jaw. They are situated about opposite the center of the trans- 
verse portion of the teeth, the lenjj;t!i of which may be about three times 
as ;;reat as the major axis of the nostrils. 

The colors of the younjjfer specimens of this species in alcohol are a 
pale salmou-yellow, lighter beneath; the back and upjter part of the 
sides sprinkled irn'fjularly and thickly with sharply-deliued blackish 
spots, lookinjj like };rains of c()arse <junpowder. These s[>ots vary in 
si/e with the specimen, and are jiciierally lar<;cr towards the dorsal line. 
With aj;e, and sometimes in yoiiiincr specimens, the borders of these 
spots are less distinctly delined, and the };round «'olor between them

I''l(i. i;!. Sjiilirinf ri'l'i,: No. TOu:!. ('iuli.slf, I'a. ; ]. 

Pupil small, illiptical, major axis horizontal, hrassy, with horizontal 
dark line. General color dark salmon r<'d. Whole upper |»arts marked 
with rounded si)ots, largest along back, about size of the eye and less, 
of black or dark. Iletwcen these spots is a clouding of dark red 
dish-brown, as if the black of ui)per parts had run after being tirst 
put on. ]''re(piently, however, there is an obscure areola of the ground 

color around the sjtofs; on sides of body iwid t.iil, external poili. f 

limbs, less of the interstitial dark reddish-brown. Wliole under surface 
sprinkled with minute black dots, larger towards the chin. Ivxtreme 
edge of snout blackish, as also of lower Jaw to a Ii'ss degree. 

Individuals vary somewhat in coloration; sometimes the dots on the 
belly are more aggregated towards the center, sonu'times the interstitial 
color on back purer, so as to dcliiie spots better, while agein, on theot 
hand, the whole upper parts aic so much shaded with the reddish-brow u 
as to nearly obscure the black spots. 

The eye can be retracted or protiuded as in the ligures, and also con- 
cealed by the approximation of the lids. The transparent lower li*i 
can be brought up and over lower half of the eyeball. 

in yoiing individuals the colors aie much purer; the whole body

States east of the Mississippi IJiver as far noith as Maine, and (!orre- 
si)on(ling latitudes in Canada, and .south into Texas and Khu-ida. 't 
chietly abounds ii! the hilly and mountainous .sections. It is especially 
atpiatic in its habits, and i.- found on the ground only alt( trains. It is 
not unfre<iiu'ntly found under b.irk of fallen trees in damp situafioiis, 
but its ciii.'f haunts are cold springs. Here, beneath st(MR'S, it may 
be always found, occupying, if possible, the tissure from which the lim-

imrcnt nuMliiiin witli tlie brilliiiiicy of.i straiifjo i'xolic, ratlier tbivu tlio 
piillor ot iv ilweller iu the cliill.v (k'|)tlKs iiiid dark recesses of ii cavo. 
Tlioy walk delilu'riitcly, ami swim with snmo activity, moving, as do 
other sahunaiiders, with the limits pr«'ssed to the sides and the body 
and tail undulating laterally. Their movements are not so active as 
tiioso of some other species. They arc vei-y harndess and, though I 
have handled a great niiiidter of them, have never seen them attempt 
to bite. Their food consists of insects. 

r«r/f7/<'.v.— Occasionally a spei^imen is found which is of a uniform 
grayish-brown. Dr. IC. K. Gait sent me snch a one front Staten Island, 
Xew York. Two forms have been distin,i;nished by Trofessor llaird 
which may rank as sid)species : tlie S. riihcr slirticcpH and the »S'. ruhir 
mtnitaniis. They are described below. 

The manner in which the characters which »listinguish these sub- 
species are found singly in variojis individuals illustrates wt^ll the con- 
dition of a protean species. Thus of the si>ecimens with sixteen costal 
l>lica'. refciable to S. r. monfunus, where t!ie width of the head may 
be one-sixth the length to the j;roiu, two specimens measure thesame, 
Oft and (t'i{ iu the same, ami another (i|, and another (.'{S4S) 7 times. In 
one the posterior part of the par^sphenoidal patch is widened, as in the 
Msual form. Ii; two specimens (.WTO-TO.'M) tlie sixteenth pli(!a falls over 
the femur and does not descend before it; the vomerine series of both 
are angulated. In Td.'ihf, from the same locality as TOM, all the char- 
acters are those typical of S. r. ininitainis. 

In two specimens having the head and coloration of var. IJuber, from 
Miitaw, Ala., one has lifteen plicie and angnlat«' teeth, the other sixteen 
plica' and curved series of tet'th. In a number of >S'. r. nihcr from Ab- 
Iteville, S. (!., one has sixteen plica-. In this variety the width of the 
head enters the, length to gn»in usually tivv times, but varies to i}.\, r)!|, 
and in 7(L'.{, ii\ times. 

In the typ»' of I'.JhtrissimiiN, this relation is 1 to (iA, with but lifteen 
plica-; the truncation of the muzzle is less than described, and there 
are no cirri. In var. Sti(!ticeps a trace <d" the same is visible. The 
peculiar (U)arsc and sparst; spotting in this var. ami in »S'. r. moiiUinus 
is seen in Ruber No. 7b7."5 (half giown). 

The uniform <rolor of S. r. stirtircps is nearly equaled by Xo, 7()L*;J. and 
the white i)uni iulation of the iiits by 7b7.'> (large), though nonti are siuu- 
lar in the puiu',tulatiou of the front ; in IStO, from Eutaw, Ala., the ab- 
domen and gular region are sindlarly punctulate. 

As regards the size of the eyes in r.j!<ti'ist<iini(s, their longitudinal 
diameter measures l.o the width between their anterior caiithi. These 
sjiecimens are both small. In several small var. Ruber the measurement 
is thesai.u', and in the smaller of the »V. r. }ftlcficcp,s ; in the larger of the 
latter and of Ruber this measurement is as 1 : Li. NevTtheless, iu a nuni' 
ber of var. Ruber which have just completed their metau'orpliosis the 
proportion of front to eye is also li : 1 (Xo, oSt!)).

Viewed from in front, tlio lower outline, of the muzzle is stron«:lv 



» oneave, boniered on eaeli side by the downward extension of this 
lidfic Tlieni is a slijfht indentation of the side of the jaw behind this

Tiie outline of the upper jaw, as viewed from below, is decidedly an- 
fiular anteriorly instead of rounded. 

The eyes arc unusually larye and prominent for this section of sala- 
mainlers, and are sei)arated anteriorly by little more than one oibit's 
l("ii;:fh. The two parasphenoidal ranj;«'s of teeth are in contattt ante- 
riculy, as in S. r. montaniis, without the interval of S. r, nilnr. 

There are llftei'ii costal furrows, excluding' an axiliary one. The tai| 
is a little more than half the rest of the body. 

in alcohol the color is li};ht brownish red, paler beneath; tlu' upper 
parts and sides thinly but (piite uniformly spriidiled with small, 
roiindcti, well delined, Itlackish dots; very few of them on the head. 

As stali'd, this variety is distini,Miished from >'. rubir, as well as 
N /'. niinttdiiiis and sticticrps, by the shape ot the head, the anji'ulation 
ul tl'" uppei' lip, the much larger and more approximated eyes. The 
scaiilinessof the black specks is more as in S. r. moiituints, from which

This varit'fy in all it.s details of sliaitc, proiMMtioiis an<l ;;i'iK'raI 
otriu!tino resembles /'. ridxr. Tlie limhs, iiowever, are coiisiderahly 
smaller and weaker, and (lie external nostrils seem tolte I'lrtlier apart. 
There are lifteen costal furrow.s, e.\cludin«;' the axillary. 

The color in alcohol is a daik reddi.shbrown or Itrownishred above; 
lif-hter red beneath. The color of the niiper parts is very uniform and 
continuous, thou;;h a careful examination shows .some very obs'olete 
rounded spots ot darker on the sides. The sides and beneath an', 
evervwhere sprinkled with minute blackish dots. The head is uni- 
formly colored like the back, without dark spots, but its sides and an- 
terior portion are closely spriidiled with whitish specks, which are very 
distinct and characteristic. 

This variety ditfors .somewhat in form from S. ruber, as slated. It 
can be separated from tln^ latter by the small whitish specks on the 
mu/zlo in the uniform j^round color, typical S. ruber always havinj^' 
lar{,'er black sjiots, without any white. The color above is deeper and 
more continuous than in »S'. rubir without the distinct doisal spots 
always distinj,'uishable in it. I'he ground color appears to be of a 
much deeper red than in .S'. ruber.

sliowin^" the nostrils on eaeh side at the eorner formed with the side «»f 
the head, and with an indistinet rid<{(> riiiinin;;' down to the Jaw as in 
a. in>ri>liifriti<us, hut less marketl. Tin' top of the head is more convex, 
and not llattened between the eyes. The toii;;ue is a eiicular pediin 
eulatetl disk. Tiie teeth curve j;ently fiv.ni behind the inner nares to 
the paraspheiioid bone, not at an an;L;le, and the two lou;4itudind series 
are so close colli iniUMisly as to c.\liil>it no furrow (»f sepaiatiun. and very 
little of on(M)e!iiiid. Tlie palatine portion does not extend outwards 
licyond the outer border of the inner nostrils. 

[•idfessor l»aird described this species in ISI!> from a siiijile adult 
>p(-ciiueii can^iht in the South Mountain, near Carlisle, I'a. Siiicti 
tlii'ii several others iVoin tlillerent localities have been oiitaiiied, and 
after the renewed examinali(ui of many speciineiis of S. nilnr I am 
silislied of its distinction as a subspecies. The cohMMti'Ui is always 
appr«'ciably dillerent in the very . sk iris without loiiLjitudinal bar of 
.Moiitaims, compared with the brassy yellow iris with longitudinal dark 
bind' Jtulter. The ;iioiiiid color above is iiuiforinly and continuously 
Uiiiwnishsalmon, much as in (i. jxirjiliifrilicHs, with a few well defined 
circular spots. In IJuin'r where the ground cohu" has become dark I'cmI- 
dish brown, it is alw.iys mottled with Milliter, ami the larger and more 
iiiim -rors dark spots are iikuc obsolete in their outline. 

Tiie Iliad of Moiitaiius isnarrower and much more arched tr.iiisv'Msely. 
The snout is more truncate. The two series of teeth on each side the 
jtai.isphenoid bone come closer, .so as to be almost in contact, without 
I lie interval of S. ndnr. 

Till' body and tail are more slender and elon<;ated; the latter propor- 
,icn.i!ly consiih'rably lon-'er. Thereare 1»» costal tiirrows, exdudiii:.; an 
axillir one, instead of lo, as in iS'. riilnr. 

Tliere are Iti distinct costal j;roo\('s, excludin;;' any in the axilla. 
The tail shows similar furrows at lirst, but they soiui become indistinct. 
It is (piadrate at the base, then jjiadiially becomes more and more com- 
press, -d, with a sharp ridj-e towards the end, as in S. ndirr. lis len.i;th 
is n.'aily equal to the distance from the s • it to the ;;roiii.

The head is eh)ii;;ate(l, vcf.v iniieh depressed, liatteiied, and when 
viewed IVoin above is miieli swoUeii posterioil.v. Tlie stioiit is very 
proiiiiiieiit, protnidin;,' beyond tlic lower Jaw. Tlie nostrils are ele 
vated, lateral, siibtcrininal, and far apart. The eyes very prominent ; 
their diameter enters only once in the distance between their anterior 
j'im and the extremity of the snout. The cleft of the month is larj:e 
and imdiilafinj,'. The maxillary teeth are proi)ortionally lar<;e, espe- 
cially on the lower jaw. They are lanceolate in shape, very acute ami 
thill. The palatine teeth are iiicoiispieiioiis, rather blunt, dispo.sed in 
an open V«haped lij;ure, the sninmit of which is directed ba(!kward, 
whilst its branches extend to the internal and posterior margin of the in 
tier nostrils. There are two elongated patches (»f miiinte teeth on the 
parasphenoid, clo.seiy appro.ximateil anteriorly and diverging slightly 
posteriorly, where they are rounder and broadesi. The cordiform or pel- 
tall tongue tills the whole space of the inferior lloor of the mouth. It 
is alt ii'lied along its meitial line, whilst its sides are perfectly free, as is 
also slightly its tapi-ring tif) and its posterior bilobed expansion. 

The neck is elongated and slightly (!ontracted; a distinct ami well- 
iiiarked gnlar fold may be observed. It no doubt exists during life, 
tliongh its|)resence has been contested by some writers. 

Tlie body is siibfiisifoim, diminishing towards both extremities. The 
siih's of the abdomen are transversely folded thirteen times between 
axilla and groin. Tlie tail is almost as long as the head and body to-

Giilar fold well niarkcd; costal folds foiirfecii, not contiiinod on back 
or abdomen. The limbs, and especially the digits, are .slender; appressed 
to the side, they fail to meet by the length of the lin«ers. The form of 
the body is .slender and cylindric, and the width of the head enters the 
total length to the groin seven times. The tail is, as in .1. liifjuhns, 
eqnal to the head and body in length, cylindrical, slender, and .slightly 
compres.scd at tip. 

The thnmb po.ssesses a short phalange, but no part of it is free, as in 
A. iKfjiihris; on the other liand, all the phalanges of the other toes of 
both feet are more slender than the .1. luguhris, and the distal ones 
distinctly truncate and .slightly emarginate, with dermal thickening 
below tip. All are qnite free. Number o'' phalanges, 1-2-3-2, l-2-;}-3-2. 

Coloration.— Hides and nape greenish-gray; toj) of hea<I and dors;i|

A I'liily f^rown imlividtial of tins speeics i)resents the followiuf;' char- 
acters: The form is ratlier robust, and the head is distiii<;nished from 
the neck by tiie swollen temporal mnscles. The muzzle is short and 
wiile, with roiiuded border, and is not so contracted as in the.l. liiiia- 
/>//v. The len<;th from the end of the muzzle to the axilla enters that 
IVom the latter to the t-ioin one and a half times. The tail isof moderate 
Icnjith, equiilin,n' tlmt of the body (includinf? vent) nearly to the thora(!ic 
fbhl. TIh! width of the head enters the lenj>th from end of muzzh? to 
j;ioin live and one half times— a proportion intermediate between tho.se 
exhibited by the two other species of the fi'enus. The limbs are rather 
robust, and when ai)pressed to t!,.; .sides leave an interval of three 
iMler<;ostal spa(;es. 

The top of the head is flat, and the least interorbital width is ecpial 
to the lenj^tii from the eye to th(^ end of the muzzle and to the space 
inclo.si'd between the external borders of the external nares. The 
commissure of the mouth rises behiml the line of the orbit as in the.l. 
Iii(/iihri^. The muzzle does not project lieyond the mouth, as it does in 
.1. luiftthris. The internal nares are very small. The tongue is lar<>e 
and antero posteriorly oval, and is t'xtensively free at the sides. The 
vomero palatine teeth are in two short rows of three or four teeth each, 
which (M)mnK'nce behind the internal nares, ou a liiu' with their inter- 
nal borders, and converge, with slij;hi posterior inclination, without 
meetinfj. The patch of parasphenoid teeth is wide and subtruneate in 
front, and is undivided except towards the i)osterior ])ortion. The 
larjxe teeth of the Jaws are not so well developed as in the .1. int/Kbris^ 
ar(^ nH)re sleinler in form, and not so numerous. They <!onstitut«', the 
entire arnniture of the dentary bone, occupying; only the anteri(U' half. 
1 <!ount only four of then), and they are movable; that is, iiunniture. 
1 find no fixed oiu>s of the larji'cr size in the uppi'i- jaw. Three or four 
of the posterior imixillary teeth are like those (»f the dentary bone, but 
Ihey ;4iadiiate anteriorly into teeth of the usual type. An examina- 
tion of otherspeciuuinswill be necessai'y toascertain whether these teeth 
i»econu5 permanent or not, or whether they are developments of the 
lireedin<>' season. The larj;e temi)oral muscles, curved coi: nissure of 
the Mn)Uth, etc., so re.send)l(^ the correspondiiiii' parts in the .1. liiijiihriii, 
that I suppose their i)ermanentdtMital characters to be alike. Thennix- 
ill-ry bone projects abruptly downwards behind th(^ last nmxillary 
lOoth, formiuff a snn)(>th eil;i'e. as in A. hifiKhris.

The skill ol" the A. iiranm is smootli. Tliere are tliirteeii hiteral 
IbUls between axilla aiid yroiii, and a stroiij; pectoro jiiilartbld. The hit- 
ter rises on each side in front of the shoulder, and then turns upwards 
and forwards. It is soon changed into a narrow dermal ridge or rib, 
whieh is (Irst eonvex iii)wards and then eonvex downwards, and then 
terminates in line with the e.ve a diameter of the latter behind it. 

The feet are short, i.nd the diyits are tlattened and are obtuse at the 
tips. The pollex is only free by a slight notch, and the hallux by a 
rather deei>er one. The phalanges are: Anterior, l-2-.'5-2; jmsleiior, 
l-L'-:5-3-2. The third and (iflli anterior digits ar<' equal, while the 
l)osteriors run l-2-i"i-;i-l, beginning with the shortest. The third and 
fourth are nearly equal. 

The tail is somewhat depress(>d at the base, and beeonics round in see- 
tion to the end of the jtroxima] two -fifths. It then becomes giadually 
more compressed, until ic is quite Hat for the distal third.

ill ricthodoii. 

TUii Aiitodnx ii'canns was originally established on a half grown speci- 
men found by myself in Shasta County, Cal. A second specimen of 
the same size was sent to the National i\[useu.n by Mr. Charles Town- 
send from the same locality. The young specimens do not display the 
physiognomy of the genus, but have the usual want of character as 
coMipared with the adult. The vomerine series of teeth are, however, 
rather better developed. The typical specimen has the following char- 
acters : 

The vomerine series are straight, and do not quite meet on ihe mid- 
dle line. They are entirely behind the nares, and do not extend exteri,)r 
to them. Tiie paras[>henoid patches are united into one, and are well 
separated from the vomerines. 

Form rather stout, and the tail short, etpiiding (from vent) the length 
of the body (with vent) to the gular fold. Costal folds, 1'}. IIea<l a 
longitudinal oval, with rather narro\.ed and not truncate niuzzK' ; its 
length (to occii)nt) contained o'-J times in length from muzzle to groin. 

Limbs short; wlu-n pressed along the side they aresei)arate(l hy three 
intercostal spaces. The digits are short and the internal ones are rudi- 
mental. 

The color is black everywhere, and the superior surfaces are dusted 
over with minute light specks.

This small species bears a strong reseniblaniie to the Spclerjx.s hi- 
line(ttu.s Vtvaaw, and, apart from generic characters, may be known from 
it by the rounded tail, the paler-colored abd()men, and the light bar 
iVom the eye to the angle of tiie mouth. Its proportions are stouter 
tiian in Plethodon cincrciis crijtliyonotnH, to which it also bears some re- 
.send)lanee. 

Tiie costal folds are thirteen, but fourteen if that which is immedi- 
ately above the groin be counted. The hrst falls immediately into the 
axilla. This is the chaia(!teristic an-angement in I>.fnsc<i also, while in 
/>. itiiiru the fold above the groin usually extends to it, and is the twelfth, 
vviiilc; that which corresponds to the first of the species before named 
I aiisjust in ailvaiuie of the axilla. Though this is typical of />. ni(;i<i 
occasionally another i)!ica appears above the groin, and the twelfth is 
.-lightly in front of it. 

The pores in I>. ochroi>h(va are very difUcult to observe. In a few 
specimens I have seen a few of those of the lov.er .series ; the upper I bc- 
lii've to be wanting. The gnlar fold is distinct, and another vertical fold 
coiiiinences behind its extremity, and turning longitudinally, extends 
more or less distin(!tly to the orbit. As in other species, the derm a<l- 
lieres closely to the frontal bones and is more or less rugulo.se. The 
head is oval, with rounded depressed muzzle; its greatest width en- 
ters the length to the groin .~»'rj times. The commissure of the mouth is 
.--lightly llexuose. 

The appressed limbs fail to nu-et by four intercostal spaces. The 
inner «ligits of both feet are short but free, longer than in IMethodon 
species of similar size; the othei- digits are also longer and more dis- 
tinct ; proi)orfions, l-l-2-.'5, l-r»-L*-l-;i; only three phalanges in longest 
t.:es. The tail is quite slender, and oidy compressed at tip; in sonu^ 
there is a keel above on the distal third, but never any dermal lln. 

The vomerine teeth are very few and small when present ; they are 
often wanting. Their basal line is on a ridge, which is convex back-

wards, nearly coiitiimous medially. Tlie panisplieiioid (eetli staml on 

two narrow plates, wbicli arc well separated, especialjy behind, and are 

shortened; anteriorly they only reach to near the niiTldlc oftlic orbits. 

Tiie mandibular teeth present pecularitics in the male, by which it may 

l)e readily distinguished from the female. In a large number of speei- 

mens the oral commissure is but little undulate, and the mandibular 

teeth though longer medially, arc continued to near the basis of the 

coronoid i)rocess. The nuilcs exhibit a strongly flexuous commissure, 

and the alveolar margin of the mandible is dee])Iy concave below the 

front of the (ubit, an<l is edentulous. The distal portion is abruptly 

convex and is armed with long teeth. The margin is slightly concave, 

anterior to this point, ami finally rises again at the symphysis, Miiicli is 

l»roiiiin('iit and protected externally by a pad of crypts as in />. /kscun. 

The structure of the males is in the luaudibular dentition (juite that 

of the genus Autodax ; the A. fcrrcits presenting the characters but 

little more stiongly. No such sexual dil!ereiu;e can be found in the 

I), /'itsrd, though the commissure only may be sometimes more (Icxu- 

ous in uuiles. The Jaws antl dentition in the 7>. iiifjra do not dilfer in 

t!i(! two sexes. I have observed that two of the many males of />. ovhro- 

^>//fm possess the female denition. The tongue in I). ochviq)hnt( is an 

elongate oval, cousideiably free behind. 

The color of females is a bright brownish yellow, fading to dirty white 
below, with a dark brown shade on each side from the eye to liie end 
»)f the tail, which is daikest above ami gives the dorsal space the char- 
acter of a band. There is an irregular scries of brown dots along the 
vertebral line. .Males are rather larger and usually darker in color ; 
thus the dorsal baml is brownish, the lateral band blackish, and tlu^ 
dorsal spots more distinct. In most speciuu'us of both sexes there is a 
light band from the eye to the rictus oris, and the belly is idways im 
maculate ; the gular region nearly always. The testes and v is deferens 
are covere<l with black i»igment ; no i)igment on the peritonu'um ol the 
female.

marked with spots on the upper surfaces, which are "disposed without

This, perhaps the most abundant salamander in North America, is 
(luito variable in coloration, but not in proportions and struettiral jte 
culiarities. Tiio.so of the latter which characterize it are the presence oi' 
fourteen costal plicae; one well, and one little developed lateral se- 
ries of mucous pores; the equal and regular distribution of teeth on 
the mandible of males ; the compressed tail keeled above and tinned 
distally ; the presence of a tubercle in the anterior canthus of the e.ve ; 
the marbled color of the belly. In many quarts of specimens I lind 
four specimens from southern localities; two in tlie I'hiladelpliia AiMd 
eniy from Charleston, two in the Smithsonian from IJiloxi, .Miss., whicli 
have fifteen plica', but one of the latter has fourteen on one side. In 
specimens which have been preserved in too strong spirit th(5 pores 
are rendered invisible; the same occurs when the spirit is impure or 
weak. In soft specimens, the canthal tubercle sometimes disappears, 
and in many young si)ecimens and some sidult females it does not ap- 
peal' to exist. 

The head is more depressed and the muzzle prolonged than in species 
of other genera. The eyes arc piominent; llic plica' behind them 
strongly marked. These consist of one on each sitle the head and nape, 
which convei'ge posteriorly and then turn abruptly outwai'd, to be 
continued into the gular plica. A secLMid plica extends from the man- 
dible across the rictus oris to the upper plica. A second longitudinal

meet by four interspaces when pressed to the side. The tail has a char-

tion is trigonal ; the dorsal keel increases in elevation and becomes a 
narrow tin i»osteriorly ; the extremity is attenuated. Its length is just 
ecpial to that of the remainder of the animal.

Habitat, etc. — This si)ecies lives chiefly JUiionj; the stones in the many 
shallow rivulets iind springs of the hilly and monntainons regions 
of the country. It is not so partial to deeper iind stiller waters as tlie 
Spclcriirs ruber, hut prefers the rapid and shallow streamlets; here it 
may be found under every stone, or its delicate larva may be ob.served 
darting rapidly from jdacy to place, seeking concealment among mud 
and leaves. The />. fusat is one of the most active and vigorous of our 
species. The i)eciiliiir structure of tlu^ temporal muscle and its ten- 
dons, and of the occipital condyles, with the siriiigth of the bones of 
the front, enable it to bnri'ow among stones and in earth more readily 
than the species of other genera. When pursued, it runs ami wriggles 
out of sight with the gretitest rapidity, and is (piickly concealed by as- 
sistance of its dusky c(dors. 

Professor Baird originally noticed the enritais disi)osition of the eggs 
iu this species, which I have verified on a lew occasions. As in the

Tliis i.s the most robust SiilaiiiaiHlor of tlie oastorn ro;;i(>n.s oC our 
zoological roalin; it i.s not so sIimkUm' as the (ii/rinophilusporphi/riticns, 
and isainudi stronger animal. AscompanMl with the P./usca it isiinnli 
larger, tlie tail ismoreconii)rosse(l and extensively finned, and the color 
is uniibrmly different. Mesides the ciiaracters already pointed out in 
the table, it differs from ]>.fuscii as follows: The parasfdienoid i)atcli(s 
of teeth are prolonged more anteriorly, and approach very near the 
vomerines in most instances; tliey are always i)rol(niged beyond tlie 
middle of the orbits ; their prolongation is at the same time nsirrowed, 
and in most the patches are not distinguished at this point. Tlie v(»m- 
erine series are better distinguished (though not always), being obli<ine, 
sepiirate, and not extending beyond nares. Tlie tongue is in ( ight sped 
mens examined nearly round, while it is always a long oval in the two 
other Desmognathi ; tinally, tlie only male does not po:-.sess the black 
pigment coat of the testes always present in the others, though, as in 
them, the vas deferens is black. The body is stouter, and the width of 
the head enters the length to the groin les.s than five times — in the 
others always more; this is also expressed by the existence of only 
twelve costal plica', and the fact that the appressed limbs are only s"p- 
aratt'd by 2}r intercostal s])accs. 

Tlie postorbilal plicae are not strongly marked. The mucous pores 
are well de\eloped, and the two lateral series are often distinct in alco- 
holic specimens by their white color; when they become dry they ar.' 
(liflicnlt to observe. There are two rather distant gularseiies within 
the mandibular rami on each side, and one on eacdi side exlending in 
wards and forwards from the gular jdica. The superior lateral series 
extends from the orbit to near the end of tlie tail ; the inferior round 
the humeri to each side the pectoral region.

fiisca it occurs only in slmllow stony brooks. It is, so far its known, 
conrincd to the AUeohiiny mountain ranges from Pennsylvania south-

springs in the remotest depths of the forest, where its retreat is cool 
and dark. It seeks .'.onceaime.it uiuler loose stones and sliibs of slate 
with great activity, and is not easily caught. Its habitat does not seem 
to be shared by any species but the D./tiRcn; the fijirinophilKH porpliji- 
riticiis, the other characteristic Alleghany species, haunting standing 
springs and bogs, where stones are not so numerous. Green described 
it from Pennsylvania, but IJaird, who i.s familiar with the Alleghany

Prel'rontals and pterygoids present. Parietal entirely separated from

Carpus and tarsus osseous. Vertebne opisthoctelous. No otoglossal

The hyoid apparatus in this family is like that of the IMethodontidie. 
There is a hyi)ohyal on each side, of the anterior extremity of the basi 
branchial which does not irticul.itc! with the ceratohyal. In Triturus, 
Salainandra, and IlemisalamaiidiM, it is short 'Mate 30, (ig. S) : while 
in Chioglossa it is recurved posteriorly, passing under the ceratohyal 
of each side, and almost reaching tlu basibranchial again near the point 
of origin of the ceratol)ranchi;il (Plate 30, fig. 9). It thus forms a nearly 
complete ci'ch', suj)i)orting the circumference of the tongue. This 
circle has the same function as that in Amblystoma, but is of diiVerciil 
homologicjal value. Api)ropriately to this functional resemblance to 
the American forms, the proximate extremity of the ceratohyal is at 
tached to the distal extremity of the suspeihsoriiim, but by ligament. 
In ITemisalamandra, on the other hand, it is attached to the pwri nal 
l)artof the same by ligament, thus furnishing a condition intermediatei 
between the types of (Miioglossa and of Dieinyctylus. 

This family is condned to tlie Old World. It embraces the following 
genera:

No ethmoid bone. Vomeropalatine bones, witli posterior separate 
processes, «'xtending over the i»arasphenoid, and having teeth on their 
inner margins. Prefrontals and pterygoids present. Parietals not 
entbraiting the broad frontals. No dentigerous plates on the parasphe- 
noid bone. An osseous pcstfrontosquamosal arch. Ceratohyal iree, 
(M)nne<!ted with quadrate by ligament. Carpus and tarsas osseous. Ver- 
tebra', opisthoccelous. No otoglossal caitilage. (Plate 34, ligs. 2-7). 

This family differs from the Salamandrida) oJily in its post fronto- 
squamosal arch. Kiuliments of it already appear in some members of 
the latter. 

The geneni of this family are all found in the Old World. One of 
them is represented by two species in North America. They are dis- 
tinguished as follows : 

I. Maxillary bone not reachinjj; quadrate.

The liyoid api>aratns in this fjenns is inn(^li as in thi- IMcthoilontidai 
and tii(! Salaniandrida'. Tiiere is a small liypoliyal, which does not 
aiticnlate with the ceratoliyal. In Dil'itii/riiilHs forosiis there is a .second 
lirocess on earh side posterior to tiie hyoohyal,* which nniy he honinln 
jions with tlie sinular second lateral cartilajje in Jjin(iii(il(ii>siis ttniiii 
hitns, or even with the oto^^lossal cartdajic. The ceratoliyal is divided. 
lliei)roximal half o.ssoons. Tlie first ceratol)rancliial ami epibianehi.il 
are osseons. The second ceratobranchiais ori<"inatc from a hi{j;li nic 
median longitn<linal crest of the hasibranchial. The free extremity o! 
the ceratoliyal i.s elongate, and in 7>. vitiiU'scciis it extends all the way 
to tlie inferior .snrfaee of the exterior jmocc^s of tin; oxocciptal l»one.+ 
with which it is in close contact. In the />. toyoNns it <loe,s not extend 
so far. In both species the extremity carries with it the hyosnspeiisorial 
ligament which (ionnects it with the (piadrate bone, which thus becomes 
much longer than in other genera. (Plate 4(!, figs. .'5, I.) 

What name should be applied to this genus is nnceitain, and may 
jterhaps ever remain so. The circumstances are a.s follows: In 1SI!>, in 
the Journal de Pliysi(pu', | Lxxxvill, p. IIS, KafiiM'scpu' proposed to 
rei>lace the name Triton of Lanrenti by his own name, Triturns. In 
18.-0, in the Annals of Xatiire^ for March, p. i, he says: "My genus 
Triturns is the same as the Triton of Dumeril, there being already 
another genus of animals called Triton. It differs from the Salamandra

iiiliaviiigacomprt'ssed tiiil." UiMk'rtlu.sgoiiii.slieiiiclu(k'<l fivcsiiocit'.s: 
T. Iiijpoxanthits, T fnnch , 7' rlndcNcciiN, T. ncbnlosici, am] T. minidtiis. 
The T.fnsciiti is the Iksimxjn'itlmn fuscn of IJaiid ; the T. riritlcticcns aiul 
T. miniatUH are iiiehuled under tlie present j^eniis, while the application 
of the other two names is unknown. Under the head of the T. riri- 
ihsi'cnx (p. 5), he reniarks: " it must form a peculiar subgenus Diemyc- 
tjlus, distinguished by the forefeet semipalmate, with four ecpial toes, 
the i)osterior with only tliree toes and two lateral knobs; Jaws nearly 
ecpial, eyes elliptic," etc. Immediiitely following on the same page the 
author proposes tiie subgeneric name Notophthalmus for the T. miniatiis, 
in the following language: "It has almost tli(^ chariu-tors of tlic^ sub- 
genus J)iemyctylus, but differs yet iVom it by having the toes of the 
fore leet free and unecpial, the lateral ones much shorter, whence it may 
form another subgenus Notoi»hthaImus." 

The lirst jtublication of the name Triturns makes it synonymous 
with the Triton of Laurenti, and all subse(iuent uses of the name, even 
l>y tiie same author, nnist yield to this one. Now Ijaurenti does not in- 
cludi^ a single species of J)iemyctylu8 in his Triton, so that the name 
is not applicable to the i)resent genus. It must be applied to a genus 
of Salamandrida; whose sjjecies are i>laced by Uoulenger in the section 
i' ' / of his genus Molge, which is without i»ostfronto scpiamosid arch. 

One year later than IJallnesqne, IMerrem (ISiMi) proposed the name 
Molge for a series of species wnich euibraced, with tliose of Triturus, 
one species of Dii'myctylus, iKpalnidtits {MoJ<ir pdlnxtld Sclnicid.). The 
Trituri being abstracted by (he jtrior name, Molge should remain for 
(lie last-named species. Hut it was in tiie same year that Kaliiiesipie 
proposed Dii-myctylus for the same g<Mins, and it now liecomcs a »]ues- 
tion as to the day of the year on which the works of these two authors 
were respectively issued. As IJaiini'sipie's bears the early date of 
March, I retain it un(il it is shown (hat Merrem's Tentaujcn was pub- 
lished i)reviously. On this point 1 Inae not as yet obtained delinite 
infoimation. 

The two North American species of this genus ditferas follows: 

llciid wider, lint, witlioiit keels; middle rm;iers :ind toes sliorler ; ('(dois nnifdi'in, nn- 
s|ti)tted ; liiiyi^r I>, Ioi'h.^k.i. 

I lend narrow, more, eluviiteil, ami with two lon^itiidiiial keels; middle" (iiij;eis and 
toes lon^rer ; spotted more or less tliiikly : smaller If. riridrficciin. 

r.otli of these sjtecies are aquatic iJi their habits, and they are the 
only si)e(;ies found in North America which are truly so; that is, they 
do not live on the bottom or under stones, but swim or suspend tliem- 
selves in comparatively deep water.

TIlis fine species i.s of mtlier robust proportions. Tiio hoail is wiiU' 
iiiid distinct from the neck, tlirough tiie protuberance of a postcrini' 
superior angle on eacli side. It is also perfectly tlat and smooth above, 
e.\ce|)ting a f>entle slope from a line connecting the orbits ' ) the end 
of the muzzle. The body is .slightly compressed, atid its length from 
a.xilhi to groin is just equal to the length from the axilla to the end of 
th(^ muzzle. The tail is long, exceeding the length of the head and 
body by the depth of the latter. It is very much compressed, and has 
a wide dermal border both on the inferior and the superior edges. 

Viewed from abo> e, the head is contracted t(twar<ls tlie muzzle with 
curved lateral outlines, and the end of the muzzle is truncate. It al.so 
juojects considerably beyond the lower Jaw. The iu)strils appear to be 
terminal, but directed laterally, and tiie spacte between them equals 
two thirds that between the bases of the eyelids, and exceeds by one- 
qmu ter the space between the internal nares. It also equals the h'ligth 
from tlioeye to the nostril, and exceeds by a very little the length of 
the eye-lissure. 

The upper lip begins to descend posteriorly at a point halfway be- 
tween the nostril and the e.\e, and does not ri".e again, but conceals the 
lower Jaw. Tlui rictus is Just behind the jiosterior angle of the eye. 
Anterior to this point it is Joined on its internal side by a short lamina, 
which represents the lower lip of the perennil)ranchiate species of 
lialrachia. This lip is entire) concealed, and there is iu) fold in front 
of it, on the lower Jaw. 

The tongue is oval, and very small. It is only free at the sides, and 
that but slightly. The vomeropalatine teeth are in two straight series, 
which converge forwards and Join directly between the choana'. 

The limbs are robust, the posteriiu- ones the nu)reso. Applied to the 
side, tiiey overlap by the lengtli of the postericu' foot with tarsus. The 
digits ditfer much Irom each other in length, but not so much so as in 
the 1>. riridcsccus. The second (first) finger is very short, and the fifth 
is a little longer, while the third and fourth are of usual length, the 
third the shorter. 1 iie phalanges are l-L'-;{-'-'. The toes are arranged 
iniicli as the tlnger.s, the hmger ones of m.'dinm length, and the lirst

The imiiiber of i»hahiiige.s (aken in order is: l-U-JJ-.i-L'. Thi' epider- 
mis oil the extreinitii's of all the digits is horny. Tiiere are no distinet 
palmar or phinlar tnbereles. 1 iiave not diseovered any horny phites 
on the inner sides of tlio posteiior legs, sueh as occur in the 1). rifitJcs- 
cvns (hiring the breeding season. 

The cliaraeter of the surface of the skin varies aceording to the sea- 
son and h)eaiity. In a majority of specimens the upper siiifaces are 
sinootli, but wrinkled more or less closely. In si)eeimeiis which have 
been exposed to drought, the surface becomes rough, with small liaid 
pnijections. The lower surfaces are always studded with minute lioniy 
points so as to behisi)id. These become more numerousand prominent 
in specimens where the dorsal integument is roughened. Lateral folds 
are very obscure in this species, and can only be traced on the superior 
part of the sides. Twelve such grooves may be (tounted, the first and last 
being opposite the humerus and femur respectively. There is a dis- 
tin(;t transverse postgular fold. The digits have thin dermal margins 
towards the base. The genitalia are very prominent during the breed- 
ing season, and the orifice is longitudinal, and its edges are marked 
with transverse wrinkles. Internally there is a large promiiient papilla, 
simulating an intromittent organ, which rests in a fossa, whose jmste- 
lior wall is comjtosed of a series of columnar papilhe, which radiate 
backwards and downwards. The free membrane of the edges of the 
tail is much reduced, or is even wanting, in the specimens with rough- 
ened skin.

and Ibrnis a patch on the Io:eal rej;i()M. On the body the system con 
sistf *■ a series of pores alonj? the lower part of each side. 

The coloration of this species is simple. The sides and superior sur- 
faces of the head, body, and limbs are brown, and the inferior surfaces 
are yellow. In rouj;h sjiecimens the brown becomes almost black, and 
the yellow is correspondin;;ly deep, in smooth specimens the brown is 
])ale, and has an olive tinj-'e. The upper membrane of tbo tail is yel- 
lokvi.sh-brown ; the lower yellow. 

This species has the widest I'anjie ol' any Pacific salamander, since it 
extends from San Die^o on the south to southern Alaska on the iiorth. 
It is very abundant in some parts of California, and may be seen swim- 
ming in the streams and [)onds in numbers.

There are two forms of this subspecies, which htive received the 
names of viride.scens and niiniatus respectively. These havinj"' been 
shown to be st aj^cs of one <ind the same Jininial, they are not dislin- 
l^nishi'd otlierwise than as .seasonal forms, which may be by reason of 
!iu' i'livironment lendered iternninent for a longer or shorter time. I 
l^ive, however, the ciiaracters that distinj^uish them. 

Cr.ini.il carin.i' more iirominent, and longer; tongue freer laterally; skin rough; 

cheek-pits inoro freiiuently wanting; color red form ininiiiliin. 

Cranial carina' le.s.s prominent, especially at the ends; tongue less fiee ; skin smooth; 

check [>it.s rarely wanting ; ground color olivaceous form ririihxiriin- 

Tlie form niiniatus never has a caudal fin-membraiie, while it is }>eu- 
craliy present in the form Viride.scens; but this is a seasonal character. 
Tiie characiters ab()vc mentioned are not always combined as described, 
atid one (ir another may be wanting while the others are present.

TlK'oiitliru' of till! Iiciul si'oii from above is an oval, wliirli conliiutts 
anteriorly and posteriorly, and is not distinj;iiislied from tlic neck liy 
tlie abrnpt contraction of the latter. The back is r(»ol'sha[»ed, and I lie 
section of the body a vertical oval. The leiijjth from the axilla to llie 
end of tho muzzle is Just a little less than the di.staii(!e between the ax- 
ila and the "roin. The tail is niiich compresseil tliroii<;h(int, and is as 
Ion;; as the head and body (vent iiududed). 

The muzzle, viewed from above, is triii.cateromided, and it projeitts 
a little beyond tho month. The two ridj^es o»' the top of tl.i^ head in- 
close a long lenticular open {jroove which is closed in front on the muz- 
zle, bur open behind on the occiput. (Jii their external sides is a 
shallow jjroove. There is a distinct but obtuse eant'nis lostralis, and 
the lorea' region is slightly concave. Thi^ protlle i-i slightly dt'c rved 
at the muzzle. The eye is rather large; is length exceeds a litlle the 
length from its anterior canthns to tlii' end of the muzzle, and is a. 
little less than the interorbit 1 'vidth. The nostrils are close together, 
and look upwards as well as outwards. The distance between them 
enters the interorbital space two and a half times. The eyes do not. 
project ujiwards, so that the eyelids avi' nearly plane with the front. 
The lower Jaw is only partly overlapped by the posterior paitof the 
upper lip, and there is no distinct lower lip or groove. On the side of 
the head posterior to the eye is a straight row of four jiits, the tiist of 
which is near the eye and the last is in the position of the first branchial 
lissnre. Those pits are shojtly linear and curved, as tlmugh made by 
the pressure of an instrument with a short curved edge. The tlistancis 
between them are equal to each other and to half the diameter of tin's 
eye. At the position of the posterior iiit are traces of three branchial 
lissiires in three vertical short rows of minute pits; but these are not 
always present. The (theek-pits, moreover, are fre(iiiently wanting. I 
give the results of the examination of seventy individuals of the forms 
\'iiidescous and Miniatus:

limbs are not more that hall' as thick as the hin<l lind)s. Their len^'th 
is just e<|ual to tint distance I'roiu the axilla to the end of the mu//,le. 
The scitond (first) lin;ier is very small, with but a rudiment free. The 
third lin};('r is Ion*;', ainl the fouitli still longer, while the iifth is lon;;er

1 -'_'-,'>-; i-1. In nudes in the breedin;^-season the hindlejusare thickened, 
especially the inte;;iiment of the inner side. It is then divided by tiaiis- 
verse folds, and the portions between them become corneous oi' chit- 
inous. There are thus Irom ten to twelve transv»^rse jdales on the in- 
side of the thij^lis, and an irregular nuinbi'r on the inside of the tibiii 
and tarsus. The iiidimcntal external and internal toes have a (!ap of 
the same substance. These bodies aid the male in maintaining- his hold 
on the female during copulation. 

The skin in the form Viridcscens is smooth on all the surfa(;es, but 
ralln-r closely wriidilcd. The tail has a free dermal margin or tin (of 
about etpial width and length) on both the superior and the inferior 
edges. The genitalia arc very prominent at the breeding season, and 
in the male t orilicu' is oval. It is very papillose, especially within 
till' anterior liorder. (See Plates '6\i and 11, tig. .'{.) There is i.o trans- 
verse postgular fold, and there arc no transverse lateral grooves.

The f^reatei' a<!Uteiiess and prominence of the (rrauial <aests displayed 
by tlu^ Miiiiatus fcn-m is proliably caused by the closer atlhenuiceof the 
thinner inte;^unuMits under these ciriuimstauces. Direct observations 
as to these points, however, exist. Dr. llalhnvell was the first to express 
his belief that the so called distimtt species were the same. I afterwards 
remarked, " the nominal />. miniatus is a state of />. r/r/V/cvcf/fv,'' and that 
1 have had itchan^'e to the latter in confinement. Dr. Howard A. Kelly, 
in an article in the American Naturalist, states, he " broii^'ht home a 
number of />. iniiiidtu.s (Kaf.), or little red li/ard, or red eft, and after 
keeping them in a daik box filled with saturatiMl moss, they (diaufjed 
their color from a brijfht vermilion to the olive state characteristic of the

iam Taylor has obtained a good many specimens from San Diego, in 
soutliwestern Texas, it lias not been found east of that region. I did 
not see it in the plateau country. 

Dr. lioulenger thinks that this form should be regarded as a distinct

depressed and the lores less vertical and the gular fold more distinct,

The following observations were made on tlu^ Ampliiumid:e: "Tlie

thus; they have not been previously described.* In Amphlnnut iiiians 
there is a minute non-articulated bone on the suture between the o. o. 
froutalia and piefontalia in the situation of tlie lachrymal. There are 
some a])proximations to Ca-cilia in Amphiumida-. It does not appear 
to have been noti(!ed that the * * * free nuuf'in of the frontal seems 
to foreshadow the overroolinj^ of the oibit and temporal fossa seen in 
Ca'cilia. Theic is also a v»'ry iar,i;e foramen or canal i)assinjf throii.uh

tion in Protonopsis. rurther, the jjrominent horizontal anterior inle 
lior pro(^esses of the vertebral centra are the same in Ami»hiuma and 
Ca'cilia." 

The characters assigned as above to the two families Amidiiumida- 
and Cryptobraiu'liida- are abundantly suHifient for retaininj;' them as dis- 
tinct, t The form of the occi[>ital <H)ndyles mij;ht I»e ('xcepted from this 
estimate, and the axial bone in front of tiu' parasphenoid proves to be 
abnormally cut otf in the sj)ecimen then examined. The Protonopsida- 
a^ree with other I'rodela in all of the characters p:iven, ex(!ept in the 
exclusion of the fnudals from the supraorbital border, and in the mem- 
branous characteristic of the internal wall of the vestibule. The Am 
phiumida' ditfer from other I'rodela in the presence of a huj^'e ethmoid 
bone (the one referred to .is ? vomer in the diajjuosis above (jiioted), in 
the presence of temjtoral ridjj^es, and of two anteriorly directeil liypapo- 
j)liyses of the precaudal vertebra-. 

It is interestinj;' to notice that three of the four eharaeters Just cited 
are shared by the Ca'ciliidie. The jiresence of the ethmoid is ofi'special 
importaiu;e, as it is an element constantly wanting in the I'rodela. I 
have not found it in Desmoifuathus, Anaides, Spelerpes, Aiiiblystonia, 
H;damandra, nor Cryptobranchus, nor is it present in Xecturus or in 
Siren. It is, on tlMi contraiy, always present in rjeciliida't (see Plate 
IX, .'5). The double anterior hyi)apophyses ar«' otherwise conlined to the 
same family. 

The characrters of the hyoid an^hes also distinj^uish this family from

and in the i)resence of the three succeeding epibranchials. 

This family is only known from Is'oith AnuMica. 

There is but one genus of this family, which is defined :..? follows:

The only portion of the shoidder girdle of this genus which is o.ssified 
is the scapula. The <'ora<'oid (iartilages of oi)i)osite sides are distinct 
fnun each othei-, and there is a produ(!tion of the precoracoid region 
The hunuMiis i.s truncate at both extremities, making its articulations 
with cartilage only. The carpus is cartilaginous. The osscus ilium 
is quite short and slendei'; it has a long supcricu" cartilaginous portion, 
which is attached to an cipially long cartilaginous sacral rib. The 
iid'erior element is an undivided plale, which is wider than long, and 
pn'sents an obtuse angle anteriorly. The posterior portion of eacih 
is occupied by a rouml <liscoid ctssificalion. which forms the posteri(»r 
border, but docs not reach either the acetabulum or its fellow. The 
femur is rather long and has a distinc;! trochanti-r, but no head or con- 
<lyles. The arti(Mdations are (tarlilaginous, as is the tarsus, whi(th is 
also undivided. The tiliia and fibula are about one-sixth the length of 
the femur, and the fibula is a little shorter and more slender than the 
tibia. The i>lialanges in both feet are well ossified. 

The general character of these parts are desi^rilu'd in Stannius' [Tand- 
bu(rh (h'r Zoiilogie, but only as included in ihed<>linitions of the (uder 
to which Amphiuma is ref'erre<l. 

I'rofessor li'yder demonslrat<'d the identity of this genus and Munrn- 
njniis. 

The range of this genus is the Austnuiparian region. It has not been 
found west of Louisiana, nor in the Mississippi valley north of Ar- 
kansas. It oc(!urs in the Floridau district.

imlly to the extremity of the roninled muzzle. It is much depressed 
iilso, so liiat ■ha ranfje of vision is verticsil. The end of the muzzle pro- 
jects beyond the mouth, but the sides do not project. The number of 
lateral dermal {jrooves is about sixty. 

The eyes are quite small, and are separated by an interspace of five 
times their transverse diameter. They have no lids, so that the cornea 
is continuous with the cephalic epidermis. The external nostrils are 
minute, and are separated by an interval a little less than half the in- 
terorbital space. The lips are larjje and full, th(Kse of the upper jaw 
()verhan<jinjj, and concealing those of the lower except at the end of the 
muzzle. The lower lips commence on each side of the symphysis, and 
are decurved over the integument of the ramus, from which they are 
separated by a deep longitudinal groove. 

In the premaxillo -maxillary series there are thirty-one teeth. The 
series terminates below a point posterior to the eye, and a little in front 
of the rictus oris. The vomerine series form a /\ with the apex forwards. 
Tiieir posterior end is nearly but not Jiuite so far jmsterior as the ex- 
tremity of the maxillary row. All the teeth are comi)ressed, and their 
anterior edge is abruptly recurved towards the apex, so that the apex 
looks partly posterioily. The posterior nares have a valvular ojjening, 
which looks ba<!k wards and outwards a little in advance of the ex- 
tremity of the vomerine series, and nearer to them than to the maxil- 
laries. The tongue is represented by a muscular mass, which occupies 
the floor of the mouth. It is only free laterally, being separated by a 
deep groove from the mandil)ular ramus. This groove is vertically 
divided by a membranous lamina for its entire length. 

The skin is everywhere smooth. The segmental grooves are onlj' dis- 
tinct on the sides; on the belly they are indistinct, and on the dorsal 
region they are entirely wanting. There are numerous nuicous pores 
on the head. There are three rows on the maxillary region, the superior 
of which ceases below the eye, in front of a line falling perpendicularly 
(Vom it. Tiie median row terminates in one or two large pores a little 
behind below the eye. The inferior row extends farther and then be- 
i'omes transverse, and joins (he superior branch of the sui>ercili; -y row 
three diameters of the eye behind an<l within it. There is a row on each 
side of (he muzzle, which terminates in front of a line co;inecting the 
fronts of the eyes. Its place is taken by a superciliary row, which forks 
behind (he eye. The inferior half ceases behind the eye two diameters, 
while thei superior one joins the transverse continuation from theinf(!rior 
maxillary, and is continued a short distance over each temporal muscle. 
There are no distinct rows of pores on the body. The head pores may 
dilfer somewhat from those described above from a large specimen 
(No, 0.'J(>0). Thus there may be only two maxillary series, and the 
su])erciliary row may not be distinctly divided. There are two rows 
along the superior part and two rows along the inferior part of the 
lower jaw.

the toes are .'5-1 ami 2-1 in front. In the niimeron.i spe<!iiin'iis (No.

others the Tridactyle <;haracler, ij ji. All areyonii;;' and from the same

jjenera must be united. In this 1 aj;roe with him ; and after a study of 
the specimens in tln^ National Miiseiiin and in my own collection, I be- 
lieve that the two species on which these supposed j^enera rest are not

the following hinjjnaye :* 

" At the close of Angust, 18(S7, 1 spent a few days in Little Kock, 
Ark., in theeinploy of Dr. IJranner, of the Arkansas {jeologicial snrvey. 
On September 1 1 visited a cypress swunip in the vicinity of the city 
Cor the purpose of colectiiig some reptiles. During the severe summer 
drought this swamp had been almost completely dried up, and there 
was little chance to get anything except by turn'.ig over pieces of fallen 
tiiiil)er. IJeneath a log of i;onsiderabIe size I found to my surprise a 
I, irge animal (ioiled up, which b^- its smooth glistening skin I immedi- 
ately saw could not be a snake: but, having never before seen a living 
Aiiiphiuma, it took me some tinu^ to realize that I had before me one of 
these animals. After making due preparation to prevent its escai»e T 
gave the animal a i)ush with a stout stick, aiul then, no attempt at re- 
treat being made, I lifted it out of the slight depression in which it was 
lying and let it straighten itself out. Meanwhile I ha«l observed, lying- 
in the midst of the coils, a mass of moist-looking matter, nearly as large 
as one's fist. Picking this up, 1 disirovered it to be a nniss of eggs. 
This was put into a Jar of alcohol, and innnediately the young within 
(lie egg «',onld be seen writhing about, thus showing that they were in 
ail advanced stage of di^velopment. The mother offered no resistance 
on l)cing handled, and was put into a small school satchel and car- 
ried to the State geologist's oflice, a mile away, with two em|»ty fruit- 
jars lying on her. That night she was kept in an empty boat box. 
This wass(Miie eighteen inches in height, and from it she made efforts to 
es<!a[»e. Slie would er<'(!t herself in oru' corner until her head was on a. 
level with the edge of the box, but she could get no farther. Once in 
falling down she uttered a shrill sound somewhat like a whistle or the 
peeping of a .\onng chicken. A cry like that of a young duck has been 
attributed l.y some observer to the Siren, but IJarton in some of his 
writings denies the stat<'ment that such a sound is made. 

"The limbs of theses animals are very small. For instance, of this 
one, havinga length of ;>1 inches, tlu^ hinder limbs are oidy tlireefbuidis 
of an iiKih long, tln^ anterior only one half an inch. Yet, when it was 
moving over the ground or the floor, it was amusing to observe that its 
feet were put forward and drawn back, as if they really could l)e of some 
use 

"On initating this Ampiiiuuje by pushing herwitha stick she would 
snap at it viciously, and on further irritation would seize it in her Jaws 
and, springing from tin? Www in the form of a spiral, would turn rapidly 
round and round, thus twisting the stick in one's hand. Any enemy 
thus attacked would certainly find his interest in the affair fully 
aroused. 

"There an^ two points in the structure of tlie adult to which I wish 
fo call attention ; although no doubt they have already been observed

by anatoiiiisrs. The first is tliiit tlii'ie is ii little lobe of skin forming 
tlic anterior bonn(bir.v of the gill opening and ajiother forming the pos- 
terior bonier. Tliese can be very eh)sel.v a|>plie(l to eaeli otlier, and seem 
to form a very etlicient valvnlarappariitiis, b.v means of whicli tiiisnse- 
less relic of its larval life may be (•lose<l np. The other striKitnre is con- 
ne<!ted with the month. The lower lip is foiined of a fold of skin that 
is separated from the skin of the throat by a deep groove that rnns 
from the corner of the month to near the symidiysis. This fold has a 
thin sharp edge, ami is directed downward anil ontward. The upper 
lip also has a sharp edge, which, when the month is (closed, widely and 
closely overlaps the lower lip. Tliis arrangement of the lips and that 
of the gill opening seems to me to have relation to the burrowing habits 
of these animals, and are designated to pre\ent the mouth andidiarynx 
from being filled with mud. 

The eggs of the Amphinme an^ the most remarkable that I know of 
as occurring anu)ng the Amphibians. 'I'ln^ young, which now constitute 
the whole contents of the eggs, are sui rounded by a transparent <'ai)sule 
about as thic^k as writing paper, and these capsules are coniu'cfed by a 
slender cord of similar substance. It is as if the gelatinous mass sur- 
rounding the «!ggs of tlie toad simuld become ('ondensed into a solid 
covering and a connecting cord. Mow many strings there are of these 
eggs 1 <!an not determine with certainty, on account of their being in- 
extricably intertwined ; l>nt, since there are four ends visible, there are 
probably two strings, one for each oviduct. For the same reason \ have 
not been able to count the <'ggs. A careful estimate makes at fewest 
]')() of them. 

"The eggs in their present state an^ near' globular, and average 
about 0""" in diameter. Their distance ai)art .wi the string varies from 
.'itol-'"'"; fourteen of them vere counted on a i»ie<H> of the string 1> 
inches long. At this rate the whole mass would lorm a string altout S 
feet long. The connecting (uird varies from 1..")""" to one-half that di- 
ameter. The eggs greatly resemble a string of large beads. 

"The young are coiled within the ca]»sMlcs in a spiral form. On re- 
moving tiiem and straightening them they measure about 45""" in length. 
The (iolor is dusky above, with indicationsof a darker dorj^al stripe, and 
on each side a similar darker band. I'.clow the color is ))ale. The body 
is proj)ortionaIly stouter than in the adult and tiie head broader. The 
fore and the hind feet have <'acli three toes. 

"The young possess conspicuous gills ; and, since they are evidently 
near the period <»f hatching, it is l)ut fair to suppose that they would 
continue to retain these gills for some time after exclusion. The gills 
are three in nundx'r on ea(!li side, and are simply pinnate in form. The 
median gill is longest, measuring some (("'"' in length. I'rom its maiii 
axis theie arise about ten delicate twigs. Tiie other gills aic somewhat 
shorter, and give origin to about eiglit lateral twigs each. In all these 
filaments may be seen thebloodvesscis lilled with the large blood-cor-

The Amphiiima presents towards the salamanders the nearest atlinity 
to the Desmo^natliida'. The i)edunculate ()ccii)ital condyle and atlan- 
tal insertion of the temporal muscle are the same in both, and are re- 
lated to a similar form and probably similar use of the muzzle. IJy 
this arranycmeut the temporal muscle lifts the entire head bj- its inser- 
tion in the lower jaw, thus takiu}^ the place of cervical muscles. It can 
thus use the muz/leas alever to burrow in mud and stones. Amphiuma 
incaiiN i'.lso resend)les the species of Desmojjnathus in the possession of 
a chirrui) or whistle. I do not know of another American sahunander 
whicl. possesses a voice. The ej-jus in both genera arc laid in a rosary. 
I suspect that Amphiuma is a type which has de,<,'enerated from a sala- 
mander like J)csnu)gnathus, but which possessed an ethmoid bone.

This family lias been usually rejjarded as rei>reseutiiiy a distinct order 
of l>atra(;liia. I have di.scus.sed this ques'. ion under the head of tli*^ or 
der Urodehi, within which I have placed it as a suborder, which should 
bear JJe iJlainville's name Pseudophidia. Hesides the structural pecu- 
liarities already pointed out, I'eters and Sarasin have shown the 
brauciiial apparatus of (he larva to be peculiar. Inst ad of form in jj 
loops ill fibrilhe of jir. cesses of the branchial arches, the branchial vein 
and artery ramify on t lie surface of membianous bladder-like expan- 
sions of the arches. 

The numerous species of this family are distributed throu<;h(Uit all 
tropical rej;ious except those of the Australian realm. They are most 
abundant in tropical America. Their liabits ai-e subterranean, their 
lives beinji" mostly spent in the nests (»f ants, wliicii they eat. Al tiie 
proper .season tliey repair to thc^ water and dejtosit their ejJTfjs. The 
larva; pass thronj;h their metamorphosis early in life. All of the spe- 
cies are nearly blind. 

This family appears to me to have been derived from the ley-bearinj^- 
Urodela throuji'li the Amphiimida', by a jiroeess of de<feneration. Addi- 
tional evidence in favor of this view is found in the discovery by Stras- 
ser, of small cartilages in the position of the inferior elements by the 
scapular arch. This degeneration may be regarded as the result of the

darlv habitat ;i pecidiar tentacle has been developed in tiiis tamily, 
which issues from ii canal of the maxillary bone. This canal passes 
from the orbit, and the tt>ntacle which oe(ri)pi<>s it is fnrnishe<l with a 
iniisclu and nerve (Weidersheiin). It is ])robably homologous with the 
" l)aiancer" of the urodelous larva, which sometinu'S j)ersists as a non- 
retractile tentacle in s»'veral «»f the species of the salamandiine yenns 
Speleipes. 

The t'a'ciliida^ have been divided into a nnnd)er of jjenera by IVters. 
The presence or absence of minute scales defines some of these, and 
tlie form and position of the tenta(!ular openinj,' others, 8onu! of the 
latter do not appt'ar to the writ<?r to be well founded.

consist of branchinjr processes of the inte^ninient of the epibranchial 
elements. The latter are separated by branchial lissnres of the walls 
of the j)harynx. 

In the jjenns Siren the cranial extremity of thoceratohyal is free from 
the cranium, but is connected with the stapes by a stronj^ lijiament. In 
this resi)ect this };enus resembles the adults of the true salamanders, oi' 
rsendosauria, rather th an the other perennibranchiate forms, <»i- the Tre 
motodera and Amphiumoidea. In its four epibranchial ('intilaj^es, how- 
ever, if resembles the larva* of the Psendosauria, as also in the presence 
of a second basibranchial, connected with i\n', first anteriorly, and ex- 
pandiiif; posteriorly Tins mixture of charatiters of the adults and (»f 
the larva' of pseiulo'aurian urodela has asi^nilicance which I will fur- 
ther illustrate. 

1 have already pointed out (American Naturalist, 188,1, p. 215) that 
l»ala'oiitolo}jfy shows that the order of Trachystomata is a de;;i'iicrate 
type, if the structure of its skull, limb-arches, and limbs be I'onsidcrcd. 
1 have also reason to believe that there are indications of a retrojiiade 
metainorphosis to be found in the history of its branchial apparatus. I 
was for a long time at a loss to account for the i'lirioiis condition which 
1 had observed in the branchia' of the sirens. The fringes are freipiently 
in a state of apparent partial atrophy and inclosed in a common dermal 
investment of the branchial ramus, or all the rami are covered l»y a 
common investment, so as to be absolutely functionless and immovabU^ 
This character observed in the Pucudohnnnltus striutiis, iiiiva orifjin to 
its separation from the {jeniis Siren. The character is, however, comnioii 
to the Siren lacertina at a certain age, and the real diH'erence betwt'cn 
the genera depeinls on thedilferent number of the digits and pharyn- 
geal tissnres in the two. 

1 have also observed that the liinctionless condition of the branchia' 
is universal in young individuals of the tSiren lacertina of live ami six 
inches in length, and that in a specimen of a little over three inches 
they are entirely rudimentary and subepidermal. 1 have, in fact, no- 
ticed that it is only in large adult specimens that the branchia' are fiiby 
developed in structure and function. The inference from the specimens 
certainly is that the branchia' are in the sirens not a larval character, 
as in other perennibranchiate Batrachia, but a character of maturity. 
Of ct)urse only direct observation can show whether sirens have 
branchia' on exclusion from the egg; but it is not probable that they 
dili'er so much from other members of their (ilass as to be without them. 
Nevertheless, it is evident that the branchia' soon become functionless, 
so that the animal is almost if not exclusively an air breather, and that 
functional activity is not resumed till a more advance<l age. That Sirens

may lu' «'X('lii.siv('I.v air ln'ciitluTs I have sIkiwii l»y tibsei'vations on a 
spcciiiKMi in an aqnatinni wliicli, I'oi' two nioiilis, prohalily from tlui at- 
taclvH of n«hes, had no lirancliia' at all. (Sco .lourn. Ac, I'liila., 180(}, 
p. OS). 

In explanation of tliis tact, it may ho romarkoil that this atrophy can 
not bu a<;roiinto*l lor on th(> .snp|)osition that it is S(>as(nial anil due to 
the drying; np ol the a(|nati('. habitat of the sir(>ns. The tionntiies thoy 
inliabit arehnmid, rec«'ivin<;,Mhe heaviest rain-fall of oni' ICastern States, 
and there is no dron<;ht. The only explanation appears to me to be that 
the present Sirens iuv t\w descendants of a terrestrial type of Hatraehia, 
which passed thron^h a metamorphosis lik(>. other nu>mbers of their 
class, lint that more recently tlu-y have ailopted i permanently aqnatic 
life, and have resnmed their branchia- by reveision. 

This hypothesis is (^onlirmed by the relations of the stapes to the 
suspensor of the lower jaw. It is not coniu'cted with the quadrate 
cartilafje, as is the case with the I'rotiida', Cryptobranchida', Amiddn- 
mida', and the larva- (»f salamanders, bat is distinct and is connected 
posteriorly v/ith a stapedius muscle as in adult salamandeis.* (See

In ijonenil form llils iiniiniil is quite, I'loiif^uti', ;iii(l tlic t.iii is coiisid- 
enibly shorter tliiin tlic body, inoasiiriii};- one half of the h.-ngth of the 
head and body together. The head is a h)nger or shorter oval in out- 
line, and the end of the ninzzle is rounded, truncate, and projects be- 
yond the lower Jaw to a moderate degree. In prolile it is depressed, and 
the line of the front gradually descends from behind. The fore limb is 
short, measuring Just half the distance between its anterior base and 
the end of the muzzle. 

The eyes are very small, ami are covered by a thin epidermis or 
cornea. They are situated just one-third the distance between the end 
of the muzzle and the base of the anterior external branchin. The 
ui>per lip is pcndidous at the sides of thi; mouth, overlap])ing the lower 
lip. The latter is free and pendulous at the sides, and is bounded be- 
low at the base by a deep groove, which mayor may not be continuous 
round the entire chin. Thus it is comi)lete in seven specimens and in- 
complete in eighteen. liotii conditions are seen in specimens from the 
same locality, as, for instance, those from Kiceborongh, (ra., and ^lata- 
moros, in Tamanlipas, The external nares are well separated from 
each other, and are short transverse slits. 

The superior horny sheath is quite short, covering only the prcmax- 
illarybone. It has a sharp edge, and is black in <!olor. The lower 
sheath is much longer, covering the entire edge of the dentary bone. 
It is also sliari) edged and black. The tooth patches vary in propor- 
tions in dilferent individuals. Tiiey are distinct from each other, but 
are in contact anterioi ly ami diverge i)osteriorly. The teeth are small 
and acute, ami are arranged in numerous transverse rows in each patch. 
In adult individuals the patehes have an oval outline, but their width 
varies, and in some others and in immature examples they are more or 
It ss linear. Thus in one specimen from Matamoros the vomerine teeth 
arc reduced t(. a line on each side, the two forming a A. In one from 
(Icorgia the same arrangement occurs, but in a second from the same 
locality, and in every other respect similar to it, the teeth are in a wide 
patch. In two others the patch is intermediate in characters. The 
surface of the tongue is smooth, not displaying plica' or large pappilhe. 
It occui)ies nearly the entire tloor of the mouth. The interrial nostrils 
are eaitha hole at the exterior side of the parasphenoid patches of teeth, 
at tiie point marking the posterior third of their length. 

The fingers are moderately elongate, and are perfectly free from 
dermal web or border. Tiieir lengths are in order, commencing with 
the sliortest, 5-l*-4-.'{. The third and fourth are sometimes of equal 
length. 

The brancliia', when fully developed, form a bipinnate frame-work, 
to which tlie ultimate librilla' are attached : timt is, the primary stem 
sends a row of secondary branches downwards on each side, and these 
again ternary braiuihes on each side. To the under side of these the 
fibrillar are attached. Tiiey are (juite short. Tiie entire brantdiia is 
short and not produced at the extremity, as is the case with Nccfiwiis

branches are also present. The librilla" in Siren present dillerent con- 
ditions, perhaps dependent on the character of their environment as to 
the abundance of water, etc., and indicating dillerent dejjrees of func- 
tional elBciency. I have discussed this question under the head of the 
family Sirenida*. 

The body is rounded, snbquadrate in section, and disi)lays an indis- 
tinct median <lorsal groove. The transverse j>'rooves are distinct on the 
sides and nearly meet on the belly, but are not distinct on the back. 
They vary from thirty-one to thirty-seven in number. The larfjer speci- 
mens generally have thirty-six and thirty-seven grooves, while smaller 
ones fre(iuently have only thirty-one and thirty-two. The specimens 
with thirty-three, thirty-four, and thirty-live arc of medium size ; but a 
full sized one IVom (Je()rfiia(No.4r);{5) has t]iirty-tw(),and a small one from 
South Carolina (No. lO.")!!) has thirtv-four. It was on specimens jjresent- 
iufj- the eharactersof the sujaller indivichmls above mentioned that the.V. 
iiifeniicdid of Leconte was proposed. I can not distin<:;uish it from the 
ordinary form. The skin is everywhere i)erfeetly smooth. The tail is 
comi)ressed from the base to the extremity, and for its distal half is 
(juite thin. It has a stron,n' dermal liii above and below. It commences 
above opposite to the anterior extremity of the vent, and below about 
0!ie-fourth the length of the tail posterior to the vent. 

The branchial fissures, .as remarked in the discussion of the supposed 
retrograde metamori)liosis of Siren, may be one, two, or three, on one or 
both sides. In a series of small specimens from South Carolina (No. 
Mill) the fissures are as follows: L»-l, .'5-2, L»-2, 2-2. In a similar 
series from CJeorgia (No. b"*,'},")) they are 2-2, 3-3, 2-2 larger than last; 
2-3 same size as last, and .'5-3 fully grown.

ill others it is present on the cheeks only. In ii fully grown specimen 
from iMatanioros, Taniiiulipiis, this band is continued along the side for 
one-half the length, beyond which point it is represented by scattered 
yellow dots. A second similar badly delined band originates at the 
lower edge of the axilla, and extends along the inferior part of the side 
for two-thirds the length of the superior band. These bands have the 
position of those seen in the PsciidobraHchus Hfriatiis. In a, second 
ocpially large si)eeimen from Matainoros these bands are wanting. 

The geographical range of the Siren laccrtiiia is the best measure of 
the extent of the austroriparian region of North America. It appears 
in the middle of eastern North Carolina, and extends thence throughout 
the southern Atlantic and CJulf States tiirough Texas to the west side 
of the Kio CJrande, where it ceases. Northwards it ascends the ^Missis- 
sii>pi N'alley proper as high as Alton, 11!., and eastward in the AVabash 
basin, in Indiana, to Lafayette (Coulter), and the White lliver (Jordan).

Tliis s[)ccies is iiuicli smaller than the >Sircn hurrl'uw, and dilfers from 
it in a good many characters. The body iscylindric, and the tail meas- 
ures two-thirds the lengtli of the head and body and a little more. The 
liead viewed from above has a rather narrow oval outline, and its ex- 
tremity is rounded without truncation, or sometimes acuminate. In 
profile the front descends regularly to the end of the muzzle, which 
overhangs the mouth ly a little. The ey«'s are <|uite (listin(!t, though 
small, and are on the border of the head when \ ieweil from above, but 
have moreui)ward than lateral <lir»'ction. Tlie mouth is veiy small and 
does not extend so far posteriorly as the anterior border of the eye. 
The upi»er lip is pendulous, <»verlappiiig the lower, so as to reduce the 
mouth when closed to a small aperture on the middle line in front. 
The !ip of the lower Jaw is not recurved, and there is no groovt^ pass- 
ing around the chin. The external iio.^trils aie in the upper lip, not 
very near its edge, but they are not visible from above. The distance 
between them is three <|iiarters the length of that between the eyes. 

The parasphenoid series of teeth ai'c but little in contact in front, and 
each one consists of two or thre(^ row.s. They extend anteriorly near 
to the i)remaxillary and jiostericuly to oi)posite the rictus oris. The 
choanal are round, and are at the external side of the parasphenoid 
series, one-fifth the distance anterior to their posterior extremity. The 
tongue is narrowed and acuminate in front, and its free portion is rela- 
tively longer than in the Siren Idccrtind. 

The branchia' have not the .same character as those of the Hhrn laccr- 
tina, being trii>innate on the external side only. The first is much 
shorter than the seconil, which is shorter than the third. The single 
lissure is below the ba.se of the second. I have not found a second 
fissure in this species, nor have I found this one closed in individuals with

aborted brancliiii;, as (xjciirs in the case oF the other two in Siren laver- 
thia. The limbs are short and weak, and their length enters that from 
their base to the end of the nuiz/!e two and a half times. The hiteral 
toes are st'iierally of e(iiial lenj;th, and the median one is a little longer. 
All areacnte at the extremity. 

The skin is entirely smooth, and there are thirty -fonr transverse grooves 
betwe^'n the axilhe and the vent. The crosi^-grooves are continued on 
the tail, so as to be distinct for two-thirds of its length. The tail is but 
little compressed for the proximal three fonrths of its length, the ver- 
tical section being vertically oval or lenticular posteriorly. A narrow 
dermal free border commenc^es at the end of the proximal tilth of its 
length and increases in width to the til), but is never as wide as in the 
Siren laccrtiiui and in the Xei;tniiis and Ciyptobianchns. The inferior 
deinial bonier is less extensive, existing only on the terminal fifth of 
tiie tail. The tail is relatively longer th.'n in the ISi-ren laccrtiiui. The 
Ibllittles of the skin are large, and so close together as to give the sur- 
face a reticulated a[)pearanee. There are no distinct mucou« pores of 
a dee[)er character.

iiieiices jiist below tlie braiicliitc and extends aloii^j the side of the ab- 
domen parallel with the superior band, to nearly opposite the vent. In 
some specimens a similar band extends from the viuit alonj; the me- 
dian line below to the end of the tail, but this is frequently wanting- 
More frecpiently the dermal keel and border on the superior edge of the 
tall is .yellow, and this color is sometimes prolonged on the median lino 
of the back for the posterior half or more of its length. The belly lias 
rather large, more or less longitudinal yellow spots; and the ground 
color between the lateral bands is similarly but less coarsely spotted, 
except oil the tail, where the spots are dense. The fore limbs are yel- 
low, wilh a brown tinge. 

The braiieliia' of this species display partial or entire abortion in a 
larger i)r()port ion of individuals than in the ISlrcn laccrtina. An ei»i- 
dermal sheath may inclose the tibrilla' on the external side only, or on 
the external and internal sides. In ten specimens live have the epi- 
dermal covering on both sides, three have the tibrilhe free at the lower 
edge of thebranchia, and iii two the fimbria' are free on the entire pos 
tcrior face. Sometimes the first brancliia is ihclo.sed in a distinct sheath 
from the other two, and sometimes all are distinct. The insheatliing 
mend)rane may l»e (continuous at the inferior edge of the branchia with 
the epidermis of the throat. In this ca.se a small fissure remains, cor- 
responding with the one on the pharyngeal wall. 

This sitecies is .so far only known from Georgia ami Florida. From 
the latter State 1 have received it from Volusia.

Vertebral bodies mulividod, separate proatlas wantiii};. Vertubne 
very lew, on account of the anterior attaclnnent of the pelvis and the 
disappearance of some and fusion into a sin^^le styloid bone (the uro- 
style) of others of the vertebne posterior to the point of iittachment. 
Ribs very short or ^vantiIl{,^ 

Coracoid, clavicle, and scupula osseous, well developed ; procoracoid, 
epicoracoid, and suprascapula cartilaginous. Sternum present, entirely 
posterior to the coracoids. No iMiesternuni nor interclavicle, but fro- 
(luently a median element anterior to the clavicles called the omoster 
num. 

I'elvis consisting' of the usual three elements, the inferior pairs closely 
united, forminjjf a compressed body witliout obturator foramina. Ilium 
subcylindric, very elonj^ate. 

Humerus without distinct head proxinuilly, but with an epipbysis. 
Distally a globular condyle. Other long bones with epiphyses at both 
extremities. Astragalus and calcanenm elongate, forming a limb seg- 
ment. Carpal bones well developed, some of them, es[>ecially of the 
distal series, contiuent. Tarsals of tlie distal series much reduced in 
size and numl)ers. (I'hites 47, aK, etc.) 

Tlie auditory appendnges dill'er from those of the Urodela, Proteida, 
and Trachystomata in tiieir greater (-omplexity. There is a cavum 
tymi)ani or external ear and a series of ossicles and cartihiges extend- 
ing througli it, structures all wanting to tlie orders nu^ntioned. The 
stapes is, lilie tliat of thos(^ orders, an oval disk, which has no continu 
ous process, but gives origin at its middle to the stapedius muscle. 
Immediately in front of it tliere arises an osseous rod, the interstapedial 
bone. Its base is cartilaginous, and is expanded with concave surface 
lilting the convex surface of the skull. This rod terminates at tiie su- 
perior interrujition of a Hat annular carlilage {Annidus tijmptoiicus), 
which lies on the (piadrate cai'lilage and over the comjavity formed by 
its forwards tiexure. The mesostapedial cartilage is attached by a point 
on its interior face to the apex of the interstapedial, somewhat as an 
anther of a llower is attached to its tilament. Its superior portion is 
shorter, and is c(Minected with the «iiiadrate above by the mesostapedial 
liganu'iit. Its inferior portion is more or less ex[)anded distally. Its 
external face is Hat, and is applied to the inner side of the disciform 
e[tistai>edial. The latter is api»lied like a lid to the annular cartilage 
already mentioned. The mesostapedial then occupies a i)lace between 
the annular and (he epistapedial cartilages. The niembranum tympani 
tits closely over the latter. ( Plates 49-50.) 

The hyoid apparatus dilfers materially from that of the orders men- 
tioned. It can only be understood by reference to its developnu'iit 
from the larval stages. There are jiresent in the larva a ceratohyal 
on each side and a first basibranchi il, as in Urodela. The hypohyal is 
connate with the former. Posterior to the basibrancbial, two lateral 
eartilagiuous plates, the " hyobranchials," meet on the middle line.

li'iou. In some tyix'S the ossilicalion becomes more extensive, as in 
Cychtrliamphus; (Plate 7(1, li,ir. l'>.) Sometimes the third eeratobran- 
chial is ossilied, as in Alytes {I. c, lij;'. 2) and Ileniisns (/. c, liy. IS;. 

Tiie dij;its of the Salientia are apparently four anteriorly and live pos- 
teriorly ; there is <;enerally a rudimental diji'it, in adilition, on the inner 
side of each foot. Tlu^ thundt is especially well developed in tlie llylid 
frenus, Ilyi)siboas ^Va^l.; (Plate 72, 11 f>'. I'd.) The inner di^it of the pos- 
terior foot, or the internal hallux, as it is called, lias three elements in 
.some of the lianas (see Plate (»">, li((ii(( ntlchcmuKt), while in other forms 
the diyit is principally represented by a lar<>e Hat i)halan,;;e. This is 
called the spur or metatarsal tubercle in works on the subject, and it is 
sometimes incorrectly referred to the tarsus. 

The carpus of the Salientii has but two i)roximal elements, the inter- 
medium not bcinji' distii^-t. There is alar}.-!! centrale, which forms part 
of the inner border (»f the i)alm. Tin; order is further characteri/ed (ex- 
cept in the I)iscoi;lossida' ami the Aj^iossa, 7, v.) by the fusici of tiie 
iburth and (ifth (tarpalia into a single element, the unciforme. The 
other three earpalia are distinct, and the tiist is frecpiently displaced 
to form the base for the metacarpus of the thumb. The larj^c si/eof the 
astraj^alus and calcaneum have been already referred to. The tarsus is 
further peculiar in the absence of iiiterniedium and centrale and the 
absence of tarsalia, except a rudiment or two near the inner part of 
their usual position. (Plate 7.'5.)* 

INTECUMENT. 

Th(^ slij^ht attaiihment of the intej^umeiit to the nius(des is a well- 
known feature of the IJatradiia Salientia. The manner of their attach- 
ment presenis many varieties in the ditferent {(roups. It is as follows : 
A transverse partition of connective tissue holds the inte^iument alonji' 
the a(;romials and another aloiij;' the coracoids; a lon<;itudinal band on 
each side of the back (IVecjucntly marked externally by a glandular fold) 
and one below it on each side of the abdomen; a band or line aloiiiLrthe 
hinder inferior face of the thij^hs, extending;' nearly to the popliteal re- 
{•ion, i'ud a delicate one aloiij;' the upiier hinder face of the same, from 
the groove between the superior and posterior muscles.

The Jittachineuts aiv similar to the last in the Dciulrobatida', in I'iU- 
peiiipliix, and in IJracliyccplialns. In h'liffi/sOnnti nnilo tlio laterovrntral 
lino is broad, orconiposod of several series of fibers and lamina^, and in 
IJ. mroUncnse it is eoinposed of two sept.i. In P.seiulo]»lirvn(! (lie dor- 
solateral septum, as well as tlie last mentioned, is wideiu'd ; IMirynis- 
ens is similar, exeei>t that the dorsolateral is narr.)wer posteriorly, but, 
rapidly wiilening, meets its mate on the nape, foiinin,i>a broad transverse 
attachment. In Atdoptin hvris the inti',i;nment between tin; dorso- and 
ventndateral septa is ivttaehed, forminj;' a broad lateral aillierent band. 
In lihinoiihrjiniis dorsali.s this lateral attaidiment is carried so far as to 
leave only narrow free dorsal and ventral regions, while it is further 
peculiar in wantin<jr the eoracoid sei)tum, as in l)is(!o,i;iossus and Xeiio- 
pus. lOpidalea, I>ufo, and LVlta[>hryue, in their numerous species, add 
to the raniform structure the attachment of the whole dorsal integu- 
ment. The following table exhibits the other attachments.

A considerable variety is exhibited by the families of the Arcifera. 
In the genera of Discoglossida' examined (Discoglossus and IJombiiui- 
tor) the attachments are as in Itanida', except the absence of the eora- 
coid septum, as in Xenopus. On the contrary, in the Seaphioi)odida', 
the integument is more or less entirely adherent above ami below. 
The greater luimber, including the typical tbrms of llylida', add to 
the ranid arrangement a close areolar attachment of the abdominal 
skill, while it is characteristic of many species of Cystignathidic to 
possess one. or two transverse simple posterior abdominal septa. For 
tile many variations and exceptions, see under the respective families. 

Of the Aglossa, Xenopus lacks the coratioid and inferior femoral 
atlacliments; there is a «loublo or treble, but not wide, lateral adhesion 
low down, which nniy be a combined dorsolateral and dorsoveutral, or 
broad dorsoveutral only. In IMi)a all the attachments are wanting, ex- 
cejit two closely api>roxnnated lateral lines and a sui)erior posterior 
aud anterior inferior femoral. 

VISCERA. 

With regard to the dilferenccs in the arrangement and structure of 
the internal organs a great ileal remains to l»e oliserved. Ilenle (Ana-

the form of tlio cnrlilagos of tlio larjiix. Tlie size iiiid niiiiilHT of (lie 
pulmonary cells vuiy coiisidoraltly. Amoiif; Ilylida', o.siK-cially tiioso 
speck's with a loiiil voicf, tlicy are fewer and larger than in Discogloa.si- 
die and Scaphiopida'. The forms of the sinus, auricles, venlricile, and 
bulbus arteriosus, the throe aorta bows, of which the median foruj the 
aorta roots, etc., appear (piite identical externally in the Discoglossus, 
Scapliioi)us, and rhyllomediisa. Internally the two former present the 
known characters of the Annra, /. e., the union of the distinct ducts of 
the first (i)nlmonary) and second (aortic) aorta bows thro'ighont much 
of their length, the separate union of the two former and (tontinuance 
on the left side of a high free septum of tlu» bulbus, till they are finally 
turned over the riglit division toward the right, and have a common 
issue from the ventricle. A conic pocket valve is at the origin of the 
bifurcation of the ductus communis of tlie second and third aorta bows, 
but none in any part of the course of the pulmonary. 

The general characters of the venous system have iteen (b'scribed on 
page 10. The researches of Ifochstetter * and HowesI Inive shown that 
the cardinal veins do not disapi)ear in all of the Salientia. Ilochstet- 
ter in fact believes "that the vena cava inferior, instead of being 
throughout its whole extent a i>rimarily independent vessel, is a com- 
pound structure, the product of a fusion between a late-formed hepatic 
vessel and one or both of the posterior cardinal veins" (Howes). In 
IJatrachia the postrenal portions only of the (iardinals go to form the 
vena cava i)osterior, and the prerenal p(»rtions disappear or remain I's 
azygos or hemiazygos veins. Their persistence is shown to hi' fre 
quent in theDiscoglossida', in l>ombinator (llochstetter Howes), Alytes 
(Howes), and Discog'ossus (Howes). It is wanting in other Salientia, 
incbuUng the Aglossa, L'ehtdytida', and IVlobatidai (Howes). 

The general character of the brain in the Salientia may be gathered 
from Plate o(!. As I omitted, by an oversight, to refer to the charac- 
ters of this region in my anatomical introduction (pp. 1-12), I introduce 
here some rennirksoii its peculiarities in the I'roteida, IJrodela, etcr., as 
well. In the Proteida (Necturus, (Ig. 1) the tlialamencephalon is ex- 
posed by the nonprodiuition posteriorly of the prosencephalon. In 
Urodela generally (Plate U)) and in Salientia it is moderately exposed : 
in Ca'ciliida- (Plate 5(», tig. ;j) it is generally concealed. In all the tailed 
forms there is a large vascular "supraplexus" protiuding from between 
the hemispheres. Posterior to this the ei)iphysis appears; it is small 
in all the orders. The hypoi»hysis is on the other hand large. The cere- 
bellum (epencephalon) is a mere commissure in the entire class. The 
diaccelia, niesoco'lia, and metaccelia are only .sei)arated by slight con- 
.strictions of their walls. The metac(elia is covered in the Salientia by 
a triangular choroid plexus (Plate '>{> p. c). In Protei<la, Urodela, and 
Trachystomata the olfactory lobes (rliiniMicephala) are distinct; but

points. Tlie stomach has <feneraily a more loii;;;itiidiiial position than 
amoiijL;' Uiifoiiiforinia, excei)t ainoii;^ Scapliiopidie and in Ceratophrys,

cnlar coiistri(!tion in IMeiirodeina, and oik^ at the extremity of the small 
intestine in Cifsti(in(itliit>; parlii/inis. (IMates n,")-.")/;.) 

The testes are sin;;le in e\'iiin|)les of all tli > types evamincd, and not 
stri(!tly symmetrical ; they are variously situated with rel'ereiic*' to the 
kidneys. Thus in h'tiiioiilni aiircii, and Tntclii/crplKilii.s licliciiiitii.s they 
are eloii;;ate and at tin' middle of the leiijuth of the kidneys, while in 
Ili/jiishixts hofdis and tSci/lojtis romlosiis they are oval, and one or both at 
the aiitcri(n' extremity of the latter. In rin/llitmcdiisa srlrnnlcrma they 
are more than half the length of the broad kidneys, the rij^lit ori;;iiiatinj; 
at the anterior extremity of the latter, tlu^ left but little behind it. JJotU 
have their jnysterior a[)ices in close contacit at lie posteri(U' fourth of 
the leiifilh of the kidneys, which are in close connection for their poste- 
ri(n' third. In lMsco_!;lossns the testes i\n> oviform, well separated, and 
anterior, and diiriiiij; the breodiii.i,' season attain a remarkaltly lar{>e 
size. Dnriiij-' the same in Vi/stiffntitlitts lutchi/pitsthoy are not materially 
eiilarjjed, are elon;;ate, and only in contact with the kidneys for a 
small postcrioi' part of their lenjith. 

The ovaries and oviducts do not essentially vary among the Salientia 
When the latter are fnlly occn[)ied l)y eggs in an advanced stag(^ they 
arc folded, but ditVerentlv in the same species. The ovidnctts are I'e- 
inarkably slender in Ili/hi iiKsuta (Litoria (liinther), and in Scj/ 1 njti.s tha 
foiitanclle is on ca(;!i side behind the partial diaphragm, at the superior 
anterior outer angles of the liver. In several young female si>ccimens 
of linnoulva aurcn of the size of Hana Nilrd^'iat, in which the frontop- 
arietal Ibntanelle is not closed, the oviducts do not extend farther an- 
terior than the ovaries; in adults, with the cranium complete, they 
have the usual extent. In ('iistifinntlius ocellatus the ''uterine" sacs at 
the exit of th(M)viducts are of greiit size, and at oertain seasons dis 
tended with an albuniiiious gelatine, when they present several coiivo 
liUions. In spirits they occasion the ])resence of a large convoluted 
mass of coagnlnm.

tlu' J)is('o;ilossi(lii', whifli ai)pi'oac'h nearest the salamanders in their 
anatomy, the embrace is, as in those animals, round the loins. In the 
salaiiianders it is, however, the hinder feet that sei/t* the female, and 
not the arms. Amoiiu' other families the {,'enera Ciiltripes, I'eloliates, 
and Pelodytes also sei/.e the female around the waist. It is jirobable 
that this will be found to be the ease in some other jjencra not yet 
observed.* 

The sjxM'ies of Arcifera exhibit i>eeuliar structures durin.^' the breed- 
ing- season; either an exiension of the natatory membrane, or tiie 
developnii'iit of cornioiis plates or spujs, as aids 1(» prehension. Tlu'ie 
is much variety and ellieiency displayed in this jjoiiit (except in IJiifo- 
nida'), in es[)eeia] contrast to the a])i)arent absence of all but the weakest 
modifications amoii^' the iJanida'. This is in eompeiisatioii lor the 
structure of the sternum, whose lateral halves, beiii^' movable on each 
other, olVer a sli;.!;liter basis of resistance for the llcxor and extensor 
muscles of the fore limbs. 

Ill the I)isco,<i!ossi(lii-, r>ombiiiator extends the natatory membrane 
in the male, but does not develoj) horny plates. In Diseoglossiis two 
lilelike oval plates cover the superior surface of the short second diyit 
and tile tiiberelelike lirst or thumb, which is here developed as in no 
other anurous ])atiacliiaii. Dermal ruf-osities on the upper and under 
surfaces, iiiclii'linj;- the j;ular ref,Mon, are armed with corneous tips, as in 
Teiiuatoliiits. Xo peculiarity has been noticed in Alyt'.'S. The Aste- 
I'ophrydida' are unknown as to this point. 

In I'elodytes file-like jilates are developed one on the se(!ond and one 
on the third dij;it, one much lar<;eron the fort^arm, one sli<;htly smaller 
oil tlie inside of t lie humerus, and a small one on each side of the breast.

neous shield on the inner sui)erior aspect of the inner metacarpal, which 
is proloii^cd on the dij^it.

tinct oval iuUiL'sivi' oij^aiis on citluT .side of tlic iiKuli.iii line, with traces 
of a Vsliaped >;roove eounectinji' lliciii, and both are behind the month. 
In Ix'diKi <ujilis tlu'ii! are two separate adhesive orj;iins, one on eaeh side, 
behind the month, and eaeh has a slij^ht depression on its posterioi' bor- 
der. In Jlyld arluntii th«'re an' two eircudar adhesive organs close to 
the angles of the month at either side. In liomhiaator if/ncus there are 
two oval adhesive organs behind the month, whicn are in close (iontact, 
and latei'on fuse into a single organ, both having an oval dei)ression in 
the center. The follow ing oliscrvations have been made on them by 
Professor H.vder (American Natnralist, ISSS, p. 2(»;j). (See Plate 7(».) 

These organs are clearly for the purpose of enabling the yonng larvae 
to attach themselves to varions hxed bodi(>s in the water, snch as 
weeds, the gelatinous egg strings and masses from which they have 
been hatcluMl, etc. They are thns allbrded snpport and [»revented from 
sinking into the ooze to smother, and their enemies thus also donbtless 
find them a less icady prey. Th(>se disks are also shown ItyThiele not 
to l)e of the natnre of . factorial organs, bat are glandnlar, being formed 
wholly of thickened cpideiiiiis, which is elevated, its cells be<'oming 
lengtlicned or colnmnar. Tiu'ic is no mascidar sectorial apparatus de- 
veloped in c((nnecti«»n with them, and they are secretory, secreting a 
sticky mniMis or slime, wiiidi serves to fasten the young tadpole to its 
restingjilace. That an aclaal sccietion is formed is proved by the fact 
that a slimy thread of secreted matter is drawn out from the disk if the 
ytaing tadpole lie forcilily withdrawn fr»»m its support. They aie spe- 
cihcally larval organs, and persist only foi'onc! to two weeks after hatch- 
ing. They may be compari'd to the " balancers" found behiml the 
month in the larva of Andif^ stoma. In Tritons stalked suckers are said 
to be present, which l'>aIfonr comiuircs to the sessile'' suckers" of larval 
toads and frogs. Itydcr observes that he cannot see how it is ]iossible 
to liomologize the sucking «lisk of larval gar-pikes with the adhesive 
organs in larval Uatrachians, because in the fornu'r the disk is in front 
of the mouth and in the latter it is usually <|uite beidiid the mouth; 
only in one ease (llyla) are the suckers found near the angle of the 
mouth. The larva of Xcnopus has two hmg barbels at the side of the 
head from tlu' sides of the uppi'r lip. J»ut in this last case even it is 
doubtful if thcr*', is .my homology with the " suckers" of other larval 
Anura. There certaiidy «Mn not be any homology between the organ 
of the gar pike's larva and that of young toads and frogs, though it is 
proltabie that these organs in thelatttr ar.' truly homohtgons with the 
'• iialancers" ol' the larva' of salamanders of the type of Andtlystoma 
and Triturus. 

Thit'h' Inrtlier shows that, inasmuch as these structures are glatulu- 
lar, with no muscidar apparatus, tlu' terms "sucker" or "sucking- 
disk" are misnomers as applied to these organs. A belter term nnght 
he proposed for these sliuelurcs in young tadpoles, and llyder suggests 
that lluy be called ciiiilcnnal (I'lltisiiT orfjaHs.

In later st!i;,fo.s tlu' stnictiiir of tlu' jmrts about tlie iiioutli of tlie tatl- 
poles of tlui iSalieiitia furiiislR's otlu'i- cliaiactoiistic lu'ciiliaritics. I'liil 
little has been done towanls llie (lesciiption of tlie.se parts, tlie Norfli 
American* anil European t species bein,n thus far tlie only ones studied. 
These stinlies have shown that the ll.vlidic, liufonida', and Uaiiida' have 
certain characters in tin' re.uions mentioned. Uelow the horny jaws 
there is a detlexed lower lip, which displays a wide surface anteriorly. 
This surface is traversed l>y transverse seiies of short more or less hctoU 
like bristles. Similar series may or may not extend across above tiie 
upper Jaw, or on the dro()|>in>;- upper lip at each side of lln- Jaw. Tlie 
lower lii)and part of tlie uppei' lip is surrounded by short obtuse papiihe 
in one or more series. 

Now in the Ilylida', in the rej^ions mentioueil, no seri«'s ol' bristles 
extend across above the uiper Jaw except a very sliort one whi<th 
hangs over the Jaw itself; and the upper lip Ibid on tacli sidi^ of it 
bears a row of pai)illai. The papiihe form a complete boi(U'r ritund 
the lips, except the interruption at the ninldle above. In tiie Mufonida' 
there is a row of bristles entirely across the up[)er Jaw, and another 
below the lirst, interrupted at the middle re;;ion i»y the horny jaw. 
The papiihe do not extend on the upper lip-border, and art^ uninter- 
rupted at the middle of the inar;;in of the lower lip. The papillary 
border presents an anj'le iuwaids at the line of jun(;tion of the iippci' 
and lower lips. The K'anida' resemble the liufonidii-, with one excep 
tion in the airangement oi the papillary border. The latter is continu 
ous all aroiiinl below. 'J'he upiier Jaw is imrrower than in tiic liufonida'. 

JJoulenf>er describes the larva of the h'tnio alficola of northeast India 
as possessing three |)ar:)toid glands, two on the .scapular and one on the 
coccygeal region, which are not ret.iined in the ailult. Also a larva ol 
u tree frog from -lava, probably a Jtliac(H»h(»rus, which pos.sesses a ven- 
tral suct'W'ial <lisk in the position of that of a tish of the Cobii'soeida'. 

The external gills are suppressed on the right side before they are on 
the left. In th * liana rIaiiKita this suppression takes place on tlu; third 
day after leaving the egg, while tln^ left gill renniins until the eighth 
day. When the internal gills arc in functional use the water of respi- 
ration issjies, in most of tlie families, from a single lountled orilice on 
the left side, the siibcMitaiu'inis branchial chamber (tf the right .side 
communicating with that of the left side by way ol the gular region, be- 
neath the sublingual and geiii(»hvoid muscles and the integument. (S

of the most remarliabk'i histories in the zooh)<iy of the vertebrata. 

The skin wliicli covers the fore limb of the advanced tadpole is not 
a part of the true skin wliitih invests the body, sincte the branchial cav- 
ity is inclosed lonj; bcfon^ the le;;' apjtears; but it ari.ses beneath the 
mucous nuMnbrane which lint's the branchial chainbers. This anomaly 
is perliai)s a case of rcvi-rsion. The. fore-lcj;s of primitive llatraehia 
wen' no doubt external, as in salamanders, and they became iniilo.sed 
by the growth of the opcrculuni like intej-unient in the larval Salientia. 
A prolonjiation of tin; tadpole staj^e would result in a retardation of the 
•jfrowth of the foreleg an<l an acceleration of that of the opereulum. 
The urowtli of the trueskin of the inclosed rej>ion would bethus retarded 
in the Ie;4' and atrophied in the wall of the chamber. (IMate 51, tij^s. 4-(»,) 

The shoulder yii'dle appears .separated from other parts of the skele- 
ton, bctwei-n tlu' muscU's. The coraeoid and procoraeoid form a loop, 
directe«l downwards and inwards, farremoved from that of the opposite 
side, and present at this time an arciferous type in all forms of the order 
.Salientia, (See (i;;. ."i!>.) 

The characu'is of the eartilajiinous skull of the larva' of the Salien- 
tia are peculiar and veiy dillV-rent from those of the adult. The sus- 
liensurium of the lower jaw is excee<linj;ly elongated forwards, so that

identity between tlie two types it would only bo necessary to elongate 
the ilia of the latter. The developed sternal apparatus and sliouhba' 
fiirdle of th»', Salieutia is only found anionj; IJatrachian orders in the 
JJhachitoMii anil Ste,uo(rei)ha!i. Thus in I'.ryops of the former there aic 
clavicles, coraeoids, and episternuni (the last icdueed as in Trodela), 
and iu Ai-tinodou there is also an epicdavicle ((iaudry). The ]>osterior 
direction of the suspensoriuni of the lower Jaw of the Salieutia is also 
oidy found in tiu' extinct orders named, pointinji- aj;ain to this origin. 
In other recent orders these bones are directed forwards. 

Tlu^ in(»ditications ellected iu the Ilhaciiitonioiis skeleton to produce 
the Saiientian, have been jiartly llu' same as those which have produced 
the other existing orders, Tlius the triuMcrtebral centra have been re- 
l)Iaced by complete iutercentra, and several ])osterior cranial bones have 
been lost. The ilia have been greatly elongated, and in so doing have 
embraced vertebra' siu-cessively niori^ and mor«' anteriorly, so that tlM^ 
luinibcr bet w(-eu tiu ilia and the cranium has been greatly redutted, and 
tlif vertebra' posterior to the i)oiid of attachment become atrophied iu 
part and coiicrcsccnt iu i»ait. This jtro{!ess has been carried to the 
greatest degree iu the extinct family of the raheobatraehida-. Here 
thi^ ilia extend to two verrebra- in advance of the ninth or usual sacral, 
tiiiis inclosing three vertebra' in the sacrum, and leaving only .s/.i' for 
the remainder of the column. The coracoid is probably that of the 
Stegoceplialons order, as it is better developed than iu the Uhachitomi. 
The second row of the tarsus has also become icd need from these primi- 
tiv«' types i»y atrophy, while the lirst low has been I'educcd to two boues. 
as iu the M ammalia, w lii<'h have been greatly elongated. A jtarallel 
caseoccuis in the Mammalia in somn lemurs, particularly in tiie Tar-

I have discovered that th«^ (lanocephala (Trimerorhachis), ami the 
IMiachitoiiii (Tatrachys) possessed an <'Ioiigate coluau'lla auris, wiii(;h

Imniitin tjimpaiii, which may have occ.u|tied the notch external to the 
OS inh rniliin .* ( Plate ,")(», tigs. 1-7.) 

The subdivision of this rod may have given origin to three of the 
f.iur distiiu't cl«'iiiciitsexliil»ited by tin' Salieutia. (I'lates P.KoO.) The

residt of deg<'Ueracy. 

The cause of some of the modifications of the skeleton can Ite traced 
tcMise. 'J'hus the coustaiil muscular stress on liie ilia iu humping the 
back previous to leaping must have had a tenden(ry to draw it for- 
wards not only on itself, but on its verteiiral atfaciinu'Uts, whi(!h are

bonos may be tracod to a similar causo, t'spccially the stixvssupoii tlioni 
at tlie moiiuMit of starting a leap and alij;iitiiiy from it. The .survival 
of tlie elonf^ate eoracoid bone may be trat'ed to use b,\ pressure alonj; 
its lonftitudiual axis in the a<'t of seizinj;' tlie female, and possibly by 
stress in tlie opposite direction wlien en{ia{;ed in pusliin,v: objj'cts out- 
wards with the fore-feet, iirodncinfi' the etVeet of elon<iati(»n. It is not 
easy to assij^u a cause for the loss of the ])ra'sternuni and of vai ions 
cranial bones. It has been, i)eihaps, in these comparatively uniistd 
parts that one etfect of the jicnoral leduction in size and vioor which 
has occurred during; -geological time since the Carboniferous and Trias- 
sic periods, is to be seen. The loss of auditory organs is probably du(^ 
to disuse, the i<'sult <»f subterranean life.* 

The larval life of tlie Salientia has probably undergone iniportanf 
modifications during the couise of geologic lime. The characters as- 
sum«'(l by tad|)oles at dilfereiit stages of their growth are not parallels 
with known or piobably to be discovered lower forms of life, luit indi 
<'ate that tlu' larva, likt^ that (»f the Insecta, and like the mammalian 
fo'tus, has had a developmental history of its own. In support of this 
view I cite the anterior jtrodu tioii of the quadrate cartilage, which 
carries with it the eeratohyal arcth from its piimitive attachment, and 
the idfimate shortening of the same, and the return of (he cerat(»Iiyal 
to nearly its piimitive connection with the skull. I-'uiiher, ilie grad 
md iiurlosure ol the (ore leg in the external branchial ehainber is to be 
cited, the original position of the limb having been external. To these 
maybe added the development of the epidermal stickers, of the labi;d 
dermal comb, ami of ])eculiar dermal glands in some tadpoh's. None 
of these peculiarities of larval life are found in the Trodelii, and (hey 
have been gradually assumed by the lirva- of the Salientia in the comse 
of their existence, as though (lie\ were adult animals, and ]>i(»i>ably 
in obedience to the same kinil of laws. These aie (he interaction of 
the animal and its environment.

The presence or absciutc of maxillary teeth was formerly regarded by 
the author, after Diimeril and l>il»roii, as of primary value in the defini- 
tion of the suborders. On aeeount of tiie absence of teeth, a division 
Ibilbniformia was distin<;nishe<l from tiie Ai'eifera; and the tooth-bear- 
injij Fermisternia weri^ called Uaniformia. I, however, now follow Bou- 
lenger in droppinjj thes(^ divisions, since the absen<;e of teeth is some 
times of little systematica sijiiiilicance. 

In the ar(!ilerous type (»f scapidai' arch the opjiosite halves are capable 
of movements wliiiili contract or expand the capacity of tin' thorax; in 
the Firmisternia the opposite halves abut afj;ainst ea<;h other soas to be 
incapable: ot movement, thus preservinj; the siz(^ of the thora(!ic cavity. 
This arran<j;enu-nt has an important bearin<:°on the comtbrt, and perha|is 
health, of the female wiiile in connection witli the male. The embrj'.i;eof 
the foreleji'sof the lattt'r behind t be axilla* of tiM^fbrtner is very energetic, 
and is maintained by various structural aids. Thus in man.v spc-.;ies the 
inaU's develop rough and even spinous horny plates on the inm?r sujte- 
ricu' side of the tiiumb, which presses against the thorax of the female. 

Th(t iirmisternial stru<-ture is a mo<iilication of the arciferous, which 
comes later in the iiistoiy of growth, and probably in geological time. 
During the eaily stages the Firinistcinia have the movabl(> shoidder 
girdhi which cliaracteri/es those of tiie arcilerous di\ isicui, the consoli- 
dation constituting a niodiliciition superadded in attaining maturity. 
Furthermore, young Salientia are toothless, :ind (uie section of the spe- 
cies (»f Arcifera never ac(|iiire t«'elli. In these (the Ibitonida-) we have 
a group which is imperfect in two points instead of one.

sueh has been tlie i)rocess of evohition, to distinguish between two dif- 
ferent kinds of homohigoiis gronjjs. In one kind the parallel eharac- 
teraof theone group may have been derived from those of the other by 
descent, according to the priiH'iple called by Laidcester " homogeny." 
In the other case, like modifications of structure have arisen in differ- 
ent series of animals as a result of the operation of similar energies, as 
that <>f the animal an«l itsenvironnaMit. This is the principle of "homo- 
l)lassy." To the latter kind belong the imitations fonn«l to exist be- 
twtuMi tlu^ placental and didelphian mammalia. The relation between 
the aiciferous and lirmisternial Amira may be one of homogeny. We 
may then parallelize tht^ families which may exhibit true cases of de-

It i.s, however, remarkable that the ranirorni treefio^s nearly always 
have the external metatarsal bone free; the ai'ciferoiis always bound. 
The terminal i)halanfies ot the latter are eonslrn<'ted on a ball and daw 
type. In the former they are X shaped or biliii(!ate, except in (he single 
West AlViean {{enns Leptopelis. where the Sonth Ameiiean tyi»e is re- 
l»eated. 

I have also diseovered another series of parallels wliieh the {ji-nera 
of most of the families of the Salientia present, in (he de;,'ree of ossi(i-~ 
(nation of the sn|>eiior (iranial walls,* In the least-ossilicd crania wc 
llnd the snperior pari of the ethmoid still cartilaginous, (he snperior 
wall of the brain-ca.se meml)ranons, and the prefrontals represented by 
narrow lateral splints of bone. In jj^encra of slijihtly advanced type 
the roof of the eihmoid is ossified, and the prefronta's aie witter. In 
better developed ^eneia the frontoparit-tal bones ossify and close tln^ 
Ibutanelle. Tlu> lii;;lier ossilication shows itself in an exostosis of the 
snperior cranial walls, which, in further sfajics, involves the sUin, so 
that it is no lonf;er free fiom the craninm. The next stafje roofs over 
the temporal mn.scht with bone, and the hi<;hest stajje, known only in 
a ^icnusof Unfonida' (Otaspis ('<»pe), inclo.ses the membrannm (ympani 
l)eliind. TIh^ following;" table expresses tln'se facts. 

These series };ive an excellent illnstiation of the developmeiM of a 
single chara(;ter independently of othei- characters, and show how the

riorly ; in the other extreme the reverse. These features are not as ir-

Additional i»ei;uliarities in the dexclopment of Alytes, IV-Iodxtes,

The only family features as above ;iiven which seem to have a func- 
tional sijiiiilieaiice, are the struetuie of the terminal plialan>;-es as an 
adaptation to arb-.ireal life in the llylida- and the increase of raptorial 
power by the addition of another set of teeth in th»' llemiphractida'. 
Vet for the Mist-mentioiied function other arranj-ements are employed

The small proportion «)f species occurring in the Old World, exclu- 
sive of Australia, is evident, though the.v represent six families, while 
those of the Mew Worhl represent but six also. 

The tribe Arcifera was lirst delinetl audits extent and distribution 
indicated by the author in the Natural History Keview, 18(!r», thouj;h 
explaiiu'd a year previ<uisly at a meeting of the Zoological Hoeiety of 
liiiiidon. The sternal feature i-haracteri/ing it was noti«red by Stei-t- 
/.(•u, Cuvier, and others in isolated cases, but its geiu-ral signiticance 
not perceived. Dug' (Hecherches, 01) attiiluites it to the tree toads, 
the toads, and the llombinator, Alytes, and I'eloltales. In iStannius's 
Zootoude <ler Amphibien (7.'{) it is assigned to the Aglossa and I'.id'o, 
as distinguished from liana and ("ystignatlius. The chaiacters »»f llu^ 
last genus must have been talu'ii from the Old World Cassina (formerly

If we commenei^ the series of the Arcifera wi'li the great family of

lidj;*^ iiidicati's, liiuls its comjilotost (levelopiiieiit in the oxtinct j»omi.s 
Latonia, i-stablislRMl by Von i\Ieyor on the L. scif/rietli IVoni the Miocene 
olOeninj^en. A species also occnra in tlie fresh-water deposits of San- 
van (//. riifiosK], whose sahnnandei-like vertebra' have been noticed 
l»y (lervais.* Tliese animals. were nearly related to Discofjlossns, and 
iiad, like it, short posteriorly directed processes on the ribs, as in the 
ncnns Salaniandra. They were, however, inncli larger, had the I'ronto- 
piirietal Itoiics completely ossified, and the whole of tlu^ craninm 
roijilicncd externally by a dermo-ossilication. On this acconnt the 
jit'Mus has been compared with Ceratophrys, which belonj;s to the 
family of Cysti.unathida". 

In the reniainiiij^' and recent jnenera the strncture of the sternum is 
worthy of noli'. In old individuals of Disco^lossus it is sometimes tibro- 
cartilaulMoiis, as in IMpii. The sternum, hoinolo;;(»ns with the sternum of 
the i^act'rlilia. rcscndih's the united ha'mapopliysial cartila.i;es of ihe an- 
tciior ribs. In tin' ucnera in (piestion + this part is divided nearly up 
tt» the i»oint of attachment to that precedinj;", each moiety beiiij;' directed 
outwards ami backwards, and tapering into a lateral linea semiluuiiris. 
iJelwecM tlu'Nc and the pnlu's there arc in Discojilossns the usual thice 
pairs of linca- semilunares, connected on the median line by a stronj; 
I'uca alba 

In Disco^lossus the prefrontalia are strongly developetl, bcinj; in 
contact tor most of thcii' length, soiuctimes touching; the fronto- 
parictaiia. In Alylcs tlicy are also in contact throuj;hout, but ai»' 
transvcise and do not reach the frontoparietals; the fontanelle is 
lar;;cr. and llic ril»s withtmt processes; the whole animal is weaker. 
In this !^i ntis, as well as the preceding'', tin' i)upii is a vi'rtical slit; 
cIscwIk rr found in Ilylorhiiui, I'latyplcctrum, Limnomediisa, i'elody- 
tida' and Ilic Scaphi<»pida'. A species (.1. friisclicni)^ has left its re- 
mains ill tiie Miocene Ibauidcohle along with I'ala'obatrachus. Mom- 
liinaloi is similar to Alytcs in its osseous structure, except that the 
prclVoiiialia are in contact anteriorly only, and that the sacrum i>i'<s 
scnts liiil one condyle for the articulation of the coccyx, as is typical 
of the Astcropliiydida' ami Aglossa. Along with Alyt«'s and Xen- 
opus it has true ossa nasalia, which bound the external nares exte- 
riorly, iliiis explaining their anonndous jiosition in llreviceps. where 
they aie iiifeiioi. In ISombinator there is no caviim tympani ov auricu- 
lar ossicles, and the tuba' Kustachii are rudiim'utary or wanting. This 
character is said l»y Tschudi and llruch not to be exceptionless in 
adiilis, and that the tiil)ic and tympanum are always present in Ihe

No |»tery^oi(k'uni. Tonj;ue IVee, not retractile i»osteriorly. 

In Otiloplins and l*hryiM)idis* there are but eij,Mit vertebra", the atlas

teroplirydida'. The prefontals are narrow, divergent, in contact only 
anteriorly; the superior i)late of the ethmoid is small, tranverse, not 
entirely covered by the fronloparii'tals, which are but weakly ossilled

The head is wide and Hat, and t'nters the total len;;th three and a third 
times. The width at the |>()sterior borders of the tympana exeteds the 
lenjith by the diameter of the eyelid. The latter is aitoiit I'onrlilths 
tln^ very Hat interorbital rej^ion. Tin* only eianial rid;;*' is the vertical 
one which extends I'rom between the eyelid and the paidioid j^land 
along the front of the tymi>anic nuMnbrane. The lattei' is very distinct 
and is nearly round, and is Jnst half the long diametci' o*' the eye. Tlu' 
prefrontal bones are rather prominent at thecanthiis rostralis. and are 
roughened with raised points. Theendof tlu' mn/zle is strongly convex 
in protile, its extremity oveilapping the premaxiilary border. The 
nostril is nearer the extremity than it is to the orbit. The gianidar 
i-onghciiing is present on the extremity of the nose, on the posterior 
part of the vertex, on the eyelid, the prelym panic ridge, and on the par- 
otoid gland. The tongue is narrow and subcylindrical, and tlie <;hoana> 
are large and anterior. 

The parotoid glands are sul)triangular to round in outline, and are as 
wide as or wider than long. Tiie warts of the dorsal integunnMil are 
quit*' snnill, and stand nearer together on the sides than on the median 
region. The derm of the inferior surfaces is not roughened nor granu- 
lar, oxeei)t for a shoit space on the gulai' regi(Ui. but is more or lessdis- 
tiiu'tly areolate. The external surface of the arm and of the tarsus and 
hind foot and of the entire sole isspinulo.se; on the superioi' surface 
of the tibia the spinulose tul)ercles are mingled with larger tubercles. 
When the jjosterior liiid>is extended the end of tin' tarsus r«'aches the 
anterior border of the oibil, and from that point in a few instances to 
the end of the niuz/lc. The first llngeiis longei' than the second. The 
jiosterior foot is lallier small, and the web is deeply emaiginate to 
opposite the middle of the lirst (fotiith) plalange of the fourth toe. All 
the toes have a narrow «lerinal margin to their (extremities. Suhdigital 
tubercles not large, single. The two metatarsal tubcicles are distinct,

This sjn'cics is ofratlicr variahlt' cdltnatioii. 'i'lic tyjic (No. LMUS) Is 
a nniloiiii li;;Iit brown above and yt'llowisli-wliih" iiclow. In two otlici' 
siu'fiiiiciis li'oni the same locality the dorsal tiihercles are p ile, with a 
daik liiifjat the base. The latter is the prevalent eoloralion. I'oi' whili^ 
tlu'ie iiie six specimens which show if, there is only one other ol t'lie 
nnit'oiin brown tint. Specimens from Cape St. Lucas have red wans, 
with a black rin^' at the base, and have the };ronnd cohn- of the sides 
black besides. TheHiinder extremities hav(^ larjic blackish blotches, in- 
closin;;' Inberclcs which are pink. There is also a idack spot on the 
eyidid, one below the canthns rostralis running longitudinally, and one 
which extends below and sometimes behind the tympaimm. 

This is oiH' of our best marked species. Its distrilmtion exti'iidsfiom 
western Tt^xas from as far north as Kort(3oncho, and nhn\'^ both sides of 
the boundary line between the United States ami I\Iexi«'o, to the Pacific 
ocean. It is found as far south as San Antonio, in Texas (Marnoek), 
and in Lower California to the extremity of the ju'iiinsiila ^ Xaiitus). and 
in Mexico to (Juanajiiato (Dnjjes). 

The paired },dantllike rid}j,ef< '>'< the back, represented in tiie li.:;iire of 
this species in the Heport of the Cnited States and Mexican Iloiindary 
Siirvc_,-, are merely the projections caused by the dorsal and sacral dia- 
pophyses, somewhat exa.ujjferated

Avilli it in most respects. The fonn of the liead ami the ehaiacleis of

(lillereiKH's are well marked, and are as follows : The leii;,'tii of the head 
is (;oiitained in the total more than I'oiir times. Tiie lirst liii^^cr is shorter 
tliaii tilt second. The liiml le;;' is shorter, the end oC the tarsus onl.v 
reachin;;' the jiosterior border ot'the tympanum when the U'<s, isexleiided. 
The Ibrin and dimensions oC the parotoid <;laiid are very dilVereiit. The 
ylaiid is very lar<;'e, extending;' posteriorly to an aeiiiiiinate exfremiiy 
which is a little beyond above tlie axilla. The superior iMirdeis oftlie 
jilaiids are divoiv^enl. so that the total width at their apices is one and 
oiie-liall" times the width of the head at the tympana. The iiircri»»i out- 
line presents the apex of a very obtuse angle downwards at a point 
posterior to the tympanic, drum and on a level with its interior border.

I alsiiaild a copy of my description of the yoiinj;, under tlii' nanu' of 
Jl. pictiis, as it embraces some peculiar cluiiacters, probably <lue. (o im- 
maturity : 

'• I'almar and solar tuoeicles well developed, the hnj^er or inner one 
of the latter not bearing a cutlini; edj;e. Cranium plane al)ove : the 
mn/./le prodiiceil, rather narrowed, and vertically (riincate. Mt iiihnininn 
t;/iiiji<iiii very small, externally invisible; osda pharyiijica exceedingly 
miniile. Ton;;iie lar^^e, o'val, extensively free. I'arotoids superior, 
broadly oval in foiin, I'pper surfaces coveii'd with lar;^(' (ubercles; 
inferior siirlaces areolate. Limbs stout, especially (he tarsus, which 
liears a lonj^itudiiial fold. The heel reaches to the middle of the par- 
otoid ;ilaiid, and (he toes aie only webbed at the Itase." The palmar 
and solar tiiltercles are yellow, and the war(s of the body (ipped widi 
red ; si/e small. 

There is a dire('( relation be( ween (lieclima(ic coiididoiisof the rej^ions 
and the tonus of (Ins spe(;ies which inhabit them. It is well known that 
(iuMU'jii'ce oi humidity of the I'acilic rej;ion increases rapidly as we pass

Thi.s toad iias vory much the appearamu* of one of the Scaphiopida', 
and it i.s not unlikely that its habits are, like tlieirs, subterranean. 

TIk^ specimen fif^ured as Bii/o .spcciosns by IJaird in the Uejjortof the 
Alexiean boundary Survey (No. 1'<)11), frouj JVs(|iiiera, in Ntu^vo Leon 
is not tyi»i(*al of the />. vDmpuctili.s. it has feeble traces of the crania 
crests of the Hiifo nuinatus, and some lar;;o brown dorsal spots not found 
in other specimens. Three spectimens from Kansas (.V.iDi) possess similar 
iiidimeMtal crests, and a fifth specimen of the sanu^ character was sent 
me from the Wichita River, in central northern Texas, by Jacob IJoll. 
These specimens Ibreshadow the characrters of the liii/o viKjnatns; while 
not aitproachin;,' it in the devcloinneiit of the cianial crests. In the 
Dallas specimen the dorsal spots are of medium size, while in those 
iVom Kansas they are vi'ry small or waMtin.n'. I suspect that the cranial 
cliaracteis bi-loiii;- to a race whiiih ranines farther north than the true 
liiifii coin ii((cl ills, which may at some time be ic^arded as a subspecies, 
under the name of Jl, voiiiitdctili.s njuriosus. The true />'. comiKictilis 
occurs ill southwestern Texas, and ranjjes as far south in 3iexico as

IMr. »S, P. Fowior, of Danvors, Mass., after wlioin tliisintcrcsdiiii- toad 
was iianu'd, iiiakos tlie Collowiuj;" .statcaient in rejianl to tlic lialtits oC 
/». UiitiginofiusfoH'lcri, iiialctter to I'rof. F. W. Putnam, who has kindly 
alh)\vod nic to inst c the following extra(!t from it: 

"In rofi'ard to its hahits I wouhl say 1 have never been abh' as yet to 
discover it excei»t in warm summer evenings when the thermometer is 
not below (K)'^, In cool evenings they arc not to be seen at all and are. 
Iterfeetly silent. When lirst observed in the cKrli/ part of the evening 
they may be seen making their way through the grass and over the 
grounds adjacent to the pond, and when it is reacluHJ, which is usually 
about dark, they commence their singular note, which the laU^ Dr. 
Kichols thought was amatory, and which he described as a shrill mon- 
otone, continued a secoiul or more in a high falsetto voice, thrice as 
long and more trilling thi;!i the voice of Pickering's Hyla, I agree 
with I)i. Nichols in regard to the croak of this toad, excepting the trill, 
there being no trill to this reptile's note, such as we notice in the common 
toad, frciiuently long contiinuMl, and which seems to mark this species. 
J would here say I have heard the note of one loaf' in the grass some 
distance from the pond. To my ear this cioak is a sharp, disagreeable, 
uneav'thly Hcrecich. dillicult to describe, as it is uidike any sound I hav(^ 
ever heard uttered. I have heard people who live near this pond (.Fudge 
Putinim's) say that Ihey thought it resembled in a warm siMumer's night 
(when they are most active and numerous) the whoop of a i)arty of 
Indians, and that they have heard their screeching <luring the whoh^ 
night. That their note is amatory I have at present some <loubt, as il 
is continued through the warm season of the year. 1 first noticted these 
toads the pi-esent season at Judg(! Putnam's pond, in tlu' evening of 
LJUth of May, when I took several of them. 1 have not as yet been able

(»» liiid wliat I (!OIl^sitlcl• (Ikmi- spiiwii, nor liavu I seoii any copulation 
ainoiii; these toads, so often noticed anion^" tiie common species. 1 have 
seen them in tliis pond as late in the season as the last of August. 
Tliere are several ponds in the vicinity of the .jud<;e's pond, but they 
are not visited by these toads, but I have seen them in small numbers 
inclayi)its. I have a pond in my grounds that swarms in May with 
the common to.id, but is never visited by the one under consideration. 
1 have not noticed the common toad around this pond, but I now intend 
to make a search for it. In answer to your <iuestion, ' What length of 
time have thesis toads been observed in this i)ond?' I would say I have 
noticed them in this pond thirty-five years. In regard to their food, 1 
think it is dill'erent from that of the common toad, as they will not eat 
earth-worms, but feed readily upon Hies. This habit I have noticed, as 
well as my Itrother Augustus, ho having ke|»t them for some months for 
<he purpr)se, of painting them, and who has furnished me with several 
figures of this reptile in diilerent attitudes. I have noti(!ed when these 
toads are held in the hand they make a chirping noise, and when a 
dozen or moi'c are (ronfined together they make considerable noise. 
Terhaps the same may be noticed in thc(!ommon toad during the breed- 
ing season. It is very singular that those I sent you were all iiudes ; 
they were all croakers, that is certain, for by their note 1 was led to 
know wlicre to take them in the dark. I have always been pu/zled to 
know why these toads visit this ]tond during the whole warm season. 
So far as I have l)een able to judge it is for the sole purpose of croak- 
ing, for they do nothing else, or to wet their skins. The common 
toad is found everywhere, and breeds in all the still and (luiet waters 
in the countiy, whereas this supposed new specties is discovered in a 
very lew ponds, and is comparatively scarce. I have thought that 
tiiis toad was of a more spare hattit, if 1 may so speak — not so heavy or 
corpulent as the common toad, more active, as nnich so as tlu; frog, and 
full as dillicult to eatcOi. 1 think then^ is more nuifoiinily of si/e and 
color than we see in the (!omnion toads. I do not recollect in thi^ great 
numlxMs I ha\e examined to have seen a small one or i)ne dilVcring in 
color from another. Tiie dillereiice in size and (iolor is very great 
amongst oui- common toads. I have said in the vicinity i»f this ixtnd I 
have iVetpieiitly liear<l their note sonie distan(!e from the water at the 
same timi' others were croaking in the ])ond. 1 have never observed 
this anywheii^ else in my walks in the evening."

measurenuMit, one-tilth the length (f the head an«l body. This (-harac- 
ter is, however, not constant. Thus in the typical si)e('imens of the spe- 
cies (No. 2032, Canadian River) the head enters t.GfJ times into the length. 
The same is true of Nos. 14.'">2G a.jd 10195. In Nos. 4185 and 2(!t(> the 
head enters the length 4.5 times. In young si)ecimens, as is usual, the 
s;:ecific characters are not well marked, and the head is one-foiiith the 
length. This peculiarity is retained in a specimen, (No. 14,5.{S) from 
Saint Thomas, Nev., which is 3 inches in length. An excei)tional state 
of affairs is seen in two large specimens (No. 2(;.JI) from tlui head of the 
Loup F"'ork liiver, Nebraska. The head is one lifth thc^ total length, 
and the supraorbital crests are parallel, as in typi<;al specinu^ns; but 
the crests are well separated by a deep gutter behind, whose bottom is 
not raised above the nape in the usual manner. 

Brown above, with pale vertebral line and three pairs of deep-brown 
medium-sized si)ots, with paler centers. Sides and lii)s witii small 
brown spots. Femur and tibia with one iiulistin(!t brown crossbar 
each. r>elow uuilbrm yellow. The thoracic region is sometimes black 
speckled. 

This is tlie lloclcy Mountain species, as />. cixjnafus is the si)ecies of 
the plains. Its range does not appear to extend beyond the boundaries 
of the United States. Its transition to the It. I. amcricanns is easily 
perceived in seven specimens collected at Pike's Peak by John Yarrow. 
One of these is a true li. L woodhousei, while the other six vau not be 
separated from the B. I. amcriatnus. Dr. Ilallowell described a toad 
under the name of Ji. (hr.saUs in S'tgreaves' report on the expedition to 
Ziini and the Colorado liiver, p. 142, IM. !!>. There is nothing in the de- 
S(;ription nor in the tlgure to enable ns to ascertain what species or sub- 
si>ecies is represented. The evidence is as much in favor of the speci- 
men having been a H. I. amrrii'<i)ins as a />. /. woodhoiiHci,, and no lo-

In this, as in other IJiifones, the females are larger than the males; 
and the latter are usually less variegated in colors. 

The li. /. <('Heric(iiiush,\'i been regarded by some authors as a species 
distinct from the li.UciititfinosHs; but the examiiiationof a largenuinber 
of specimens of both shows that all of the distinctive characters arc 
evanescent in some individuals. Thus the supeixiiliary crests rise pos- 
teriorly in No. 2197 from Minnesota, so as to ai)proximate the typical 
lientiginosiis. In some of the spe(!iinens of No. 1*521, from Charleston, 
8. C, the extremities of tlie crests are not more developed than in No. 
2534, from the IMatte liiver, Nebraska. The sui>ratyinpanic crest is 
represented by an angle of the i)ostorbital in the great majority of spec- 
iiiKMis, but in seventeen specimens tiie fanner is quite as distiiuit as in 
nnmenuis specimens of the />. L lenfifjimtnifi. These belong to Nos. 2181, 
2193, 2172, 2174, 2197, 2557, 5372, and 19900. Nevertheless, it is true 
that the subspecies B! I. amcricdniis maintains its characters entirely 
within the range of the />. /. lentiniiiosiis, as is evidenced by specimens 
from Prairie Mer Rouge, La. (2557), Milledgevilie, C.a. (9139), Monti- 
cello, Miss., and elsewhere. 

As already deserilu'd, the par.>toid ghiiids of this species are long and 
rather narrow. A vaiietal form has them wider and renifonn in out- 
line. The live individuals which display this character are from north-

t'l'ii localities, vi/ : No. 2'){)r> from Uiicine, Wis., and U.">(>7 IVom Essex 
County, N. Y. They arc also (iliaracterizcd by the presence of a supra- 
tympanic crest and by the coarseness of their tuberculation. They 
have no distinct dorsal spots, a dark line round the bases of .sonic of 
the tubercles representing" them in sonu^ individuals. 

There are also several color varieties of this subspecies. They are not 
unfrequently met witli entirely black (var. A), as, for example, from Penn- 
sylvania and ]\richi<;an. In two or three from the latter rejj^ion the foot 
is as short as in short -footed var. woodhousei ; in one the superciliary 
iid,nvs are continent in acurveil transverse rid^e. A singular abnor- 
mality (Xo. 2r»l-t)(var. P.), fi'om Moose River, IJritish America, isdistin- 
j;uished by its yellow, orange, or i)iidcish j^round color, with thedorsji! 
and lateral spots conlluent into lonjjitudinal bands more or less broken ; 
warts pink tipped; average size below tyi)ical ; skin smoother. On 
this variety was i)roiiosed the liii/o vopci of Varrow and Ilenshaw. 

Var. C — A yellow ground with broad brown bands, having only yel- 
low lines running outwardly and ]»osteriorly ; on top of these the usual 
brown sjtots are well distinguished. The cranial ridges are highei', 
thicker, and more nearly i)arallel than usual. Specimens are of large 
siy.e; they are from South Fork of the Yellowstone, Nebraska. Total 
length, t inches 1 hue; length from end of muzzle to postorbital ridge, 
1 1..") lines. 

Habitat. — Southeastern Labrador, htckard, Proceed. Post. Soc. Nat. 
Hist., 1800; Moose Itiver, IJritish America, Ihcvlrr; South Fork Yel- 
lowstone, i/«//(/t'H ; Kansas, JIaUonrU, Proceed. Ac. Nat. Sci., l^hila., 
l.sr>0, L'51, and the Eastern and Austroriparian rej,Mons of North Amer- 
ica generally. 

Dwellers in the country are familiar with the voice of this species 
in the early spring", which is the season of the deposit of eggs. These 
are laid imtlosed in a long, thick-walled tube of tianspai'cnl albumen, 
secreted by the walls of the oviducts. These, tubes lie in long spiral 
strings on the bottoms of the ponds where they are dei)osited. The 
young hatch out early, aiul are of a darker color than those of others of 
our Salientia. They retain the dark color till near the time of the com- 
pletion of the metamorphosis. This takes t)lace at an earlier date than 
that of the Jvana', and the completed young are scarcely as large as 
tho.se of the Hyhe or of the Scaphiopus. The voice of this si)ecies 
may be heard well into the summer. It is a sonorous ur r-r-r-r r, which 
may be readily imitated by whistling whih^ one utters a deep-toned 
vocal sound expressed in the: above letters. Iinlividuals dilfer in tin; 
pitch of their notes, but a chorus of them has a weird sound well belit- 
ting the generally remote spots where they congregate, and the dark- 
ness of the hour. When not thus engaged, they often take uj) their 
abode beneath the doorstep of the farmer's house, and issue in the even- 
ing to secure t..eii' insect food. Tlu'y progress by hops, ami only walk 
on very rare occasions.

A well-niiukod varitity ot'tliis subspecies, or perlmps a distiiiet sub- 
species, i.s reiueseuled by two specimens IVoiii ^licanopy, l''la., wiiicli 
were obtained by ])r. JJean. Tlio distinguisliiiif;' i>eculiaiity consists 
ill the conversion of tlie- superciliary ridyes into llattened thickeninj;.s 
of tlio craniuin, wliieli meet or nearly meet on tlie, middle line ol' the 
fronto-parietiil re,i;ioii. They unite, leaving"' a faint line to mark the 
juuction in the larger female, while in the smaller inah^ they form two 
beveled surfaces, wlilcli unite on the middle liiit^ at an obtuse angle, 
Pcstcriorly they, with the postorbital ridj;es, have a straij^ht trans- 
verse boundary. The metatarsal internal <liyital spur is as well de- 
veloped as in many of the typical specimens, but the [tlantar tu- 
bercle is small. The web of the foot is well developed, lea chin {j^ the 
end of the fust (i>roximal) phalange. It only reaches to tht^ mitUUo of 
the proximal plialaiij;e in the ]>. /. ((iiicricanu.s. The color is somewhat 
peculiar, having a general clouded a])pearaiice above, without the well- 
defined si)ots of the tyi)ical subspet^ies Americanus. There is a pahs 
band from one i»ali)ebial binder to the otlier across the front. The me- 
dian dorsal line is indistinct. iSi/e that of fully grown H. 1. nmericamis. 
This form may bo called liufo IcntUjimmiH imclnjceithalm.

rieatl large; snout obtiiso ; .superciliary riilge.s greatly elevated and 
terminating posteriorly in a knob; upper jaw eniarginate, lower fur- 
ni.slied with a hook in front; parotoid large, renitbrni, and reaching from 
below the tymp;inum to near the shoulder; tyujpanum large; vocal 
vesicle internal; body above warty, ben«'ath granulated. 

The head is large, and without warts, except a few small ones on Ihe 
eyelids, and the mouth is large. The snout is obtu.se, and from its tip 
runs an elevated bony crest, subdividing at the nostrils, and forming (he 
superciliary ridges. These diverge and increase in elevation ,as they 
reach the posteiior part of the orbit, where they terminate in a rounded 
knob or tubercle. Their greatest height gives to the upper surface of 
the head a »;analiculated appearance; a second or postorbital ridge de- 
scends from eiich of these and completes the posterior border of the 
orbit. In consecpiemie of the divergence of the superciliary ridges the 
postorbitals are short. There is always present a short but distinct 
ridg<^ above the tympanum at right angles to the postorbital — the supra- 
tympanic. The upper Jaw is deeply emarginate in front; the lower is 
furnished at its anterior part with a distinct hook, which is received in 
the notch of the upper jaw. 

Tlie nostrils an^ small and round, placed near the point of the snout. 
Tiie eyes are large, prominent, and very beautiful; the ])upil is black, 
the iris reticulated with gold and black, and has an inner margin of 
yellow. The tympanum is large and du.sky, with a minute spot of 
a lighter shade in the center. The parotoid glands are large and 
reniform. 

The back ami sides are dusky, and covered with warts of different 
sizes; a pale vertebral lino extends from the head to the vent, on each 
side of which are found the largest warts; an irregular row of spots of 
yellowish-white exists on the think, having somewhat the appearance 
of an indistinct band, extending from the inferior and posterior i)art of 
Ihe parotoid gland to within a short distance of the thighs. The whole 
inferior surface of the animal is dirty white, with a strong tinge of 
yellow. 

Th(! anterior extremities have tiie upper surface dusky, with blotches 
and bars of dark brown; the lower surface dirty white, tinged with yel- 
low. Tilt! posterior extremities are dusky brown above, marked with 
blotches and ( r.msver.se bars of darker brown, and dingy white beneath. 

Tills species attains to the same size as the typical form of 7>. /. (imcr- 
icatiKs. A specimen (fiOl) from Florida exhibits remarkably elevated

Besides the presenci! of tuberosities of the frontoiiurietal crests and 
of a siipratympanic crest, this subspecies is well marked by the rela- 
tively elongated head. It enters the length to the vent three and a half 
times in typical examples. In some s[)e(!imens it enters the length .'J. 7." 
times, and in others four times, quite as in 7i. /. atnericanus. 

The B. h lentiginosu.s is confined to the austroriparian region east of 
Tiixas, and all statements to the contrary are based on error. It does 
not ascend the 31ississippi Valley, so far as is known.

The back of the animal is dusky brown, with a vertebral line of palo 
yellow, marked with a few scattered small warts of reddish-brown co'or. 
On each side of this line are irregular black blotches, with here and 
there a slight tinge of reddish brown. The back is covered with in- 
numerable warts and granulations of variable size and color, generally 
bhick, but the smaller ones of dusky red. On each tiank, and extend- 
ing Irom the axilla downwards toward the posterior extremity^ is an 
oblong black blotch bounded with white both above and below. 

The throat is dusky; the abdomen silvery-gray, yellowish at the. 
groin, and with a pale tinge of yellow around the vent. The anterior 
extremities, as well as the posterior, are dusky brown above, marked 
with black transverse bars or spots. Their inferior surface is colored 
like the abdomen, except the tiugers and toes, which are reddish-browu.

In some .specimens the transverse posterior partw)f the frontoparietal 
crest is broken up. It then resembles the youny of the lUi/o lenllijino- 
sus, with which it has been supposed to be identical by various authors. 
It, however, ditfers from tliis species in (he ditferently shapttl parotoid 
glands, the thickened posterior parts of tlni mandibles, and from all 
the subspecies, excei)t the />'. /. iroodliousri, in the shorter head. Tiiere 
is no doubt but that Dr. Ilolbrook was correct in rejfardiiij; this as a 
distinct species of very snutU size. The redescription of the specii-s by 
myself was due to the omission of its characteristic peculiarities from 
extant writings. Tlie erroneous locality (Sandwich Islands) is one of 
several such errors, based on the incorrect«labeling of the collections of 
J. II. Townsend, to which tlKsspecimen belonged. 

The geograidiical distribution of this s|)ecies is icstricted io tiie 
region extending from Kiiiston, N. C, to Middle Georgia and Florida,

Vertebra' proooilous ; no libs or diiipoitliysos of coccyx. Sacrum 
united witli tlie coccyx by condyle, its diajujpiiyses dilated. 

The species of tliis family are of weak organization; the fronto 
l)ariet€al bones are undeveloped in one of the four genera embra(!ed iiy 
it, and they are very weak in the others. Their atlinities are altogetli' r 
between the Asterophiydida-, and Scai)liioi)odida'. Their vertebra' only 
distinguish them from the former and their distinct bicondyloid coccyx 
from the latter. In the known genera tiie auditory apparatus is dev«'l 
oped, and the cephalic integument is tree; in noiu! is there a metatar- 
sal shovel.

basal xiphisternal piece, while in all below it is cartilaginous, as in most 
Ar.;ifera; the extreme position of the former is also maintained by the 
obliteration of many portions of the auditory apparatus. The siuiceed-

Cavum tympani and tympanic inonibrane present; sternuiii a carti-

tarsus well developed. 

This genus embraces si)ecies of robust form and of burrowing liabit.-^, 
The greater part of their lives is spent beneath the surface of tln' 
ground, but in sjuing lliey emerge and proceed to deposit their eggs in 
the nearest body of watei'. This is usually of a temporary character, 
and in adaptation to this circumstance the metamorphosis is corre 
spondingly rapid. They are very irregular as to the period of its com- 
pletion, in dry regions losing their larval ap|)endages while very small, 
while iu other and well-watered regions they retain them until fully 
grown. During the season of reproduction llicy are very noi.sy, but 
after that time disappear, and arc neither seen nor heard. They are r f' 
jdain colors. Their general fort. is are like those of their allies of the 
Old World, the species of Pelobates, or somewhat like that of toads. 

There are two well-marked species of this genns^ which differ as fol- 
lows : 

a. Collections of glandular crypts on the pnst-tympa;iic and pectoral roi^ions. 

Front wide; interorbital width onterinj; length of tibia •2..') times; vomer-

Front wide ; interorbital width entering length of tibia three times; vcnner- 
ine teeth a little behind nares; color lignt, with a net-work of brown 
bands S. coiivhii.

Head iargc; maxillary outline romuled. Profile of front a rather steep 
descent from the swollen occiimt, where the skin is thin, closely adhe- 
rent, and penetrated by osseous granules. Eyes jn'ominent. Tympa- 
num distinct, half its extent larger thanosfia pharyngea. Vomerine 
teeth in two fasiculi between and behind the posterior borders of the 
latter. Parotoids sn>all, rounded, prominent. No gland on the tibia ; 
oiin on each side of the thorax near the axilla. Skin of back minutely 
tuberculous, of sides more coarsely; below nearly smooth. Cuneiform 
process longer than in any other species of the genus, but not more 
prominent. Ileel of extended hind leg reaching posterior edge of tym- 
panuMi. 

The inner nostrils are large, open, rather elongated transversely, and 
wider apart than are the external nares. The vonierine teeth are in 
two patches, situated within the inner nares, and on aline with their 
posterior borders. The teeth in the margin of the jaw are continuous, 
tliough not much developed. The tongue is longitudinally oval, not 
emarginate behiiul in the specimen examined, where it is free for nearly 
half its length. 

The skin above and on the sides is covered pretty uniformly with 
tubercles or pustules, with smaller hard black ones interspersed. The 
lirst mentioned are wanting on the head and outer surfaces of the lii:ibs, 
wiiere the others, however, may be observed. A few pustules about 
the anus on the buttocks which show little signs of granulation. There 
is a short parotid gland Just above and behind the tympanum. 

The arm is well developed ; the hand much shorter than theforearni. 
The outer finger is very short; then the second; the iburtii is a little 
shorter than the third, or longest. All are subtruucate, or thickened 
at the tips. A thickened web may be traced between the bases of the 
lingers, although such palmation is not very evident. On the inner 
and upper faces of the two inner fingers is a black, callous thickening 
of the epidermis. The tibia is uuu;h shorter than the femur, and not 
one third the total length of body; the foot and femur about equal. 
The metatarsal bones are firmly united nearly to the end by inter- 
mediate muscle, and a web exteiuls between the tii)S of the sluut toes. 
The outer toe is very short, but little exceeding the third, and the wel) 
between it and the fourth toe is proportioiuilly reduced. 

All the toes .are much depressed, and invested by the thickened skin. 
At the base of the inner toe is an elongated, compressed, and well-de- 
veloped spade like process, with a sharp horny edge, of a black color; 
a trace of the same is seen on the inner edge of the tip of the inner 
toe. The sole is perfectly smooth, and there is no tubercle of any kind 
except the spade-like process. 

Color above, in spirits, either earth-brown, fulvous-brown, or ashy- 
brown, with a pale ashy band from each orbit; these converge again 
on the coccyx. These bands are rarely unbioken, and are sonu^times 
exceedingly indistinct; they sojuetinies inclose a pale area. Sides

This is a widely distributed and variable s[)ecies, presenting sncli 
diversity in some res|)ects as to be interesting as an example of the 
appearance of important (tharacters in the conrse of descent. It is in- 
teresting also from its habits, adapted as they are to the exigencies ol 
a dry climate, in which the o[)pi)rtnnity for aquatic life is i)recarions, 
and the metamorphosis corresi)ondingly liable to inodilication. 

I include three subspecies under thecommo:i head, which are delined 
as follows : , 

(»i'M"rally no frontopar' '-il fontanclli' ; head piano above; a liuij^itudinal pale ban.l 
on eaeli side of IkI' .; larj^er; skin tnbercnlar S. Ii. iiitennuittaiin. 

.\ frontoparietal fontanelle; head plane or convex above ; no lonj^itudinal li;.v'it 
bainls ; .skin smoother ; snia]|<>r *'. /i. hdmmoiiilil. 

A frontoparietal fontanelle; head very convex at tlie, interurbital rej^ion ; skin nearl,' 
smooth ; color.s palo ; si/.c least S. It. hoiitbij'roiis. 

I had first placed the S. h. hitcnnontana in the genus Scaphiopus, 
while the two other subspecies were placed with the S. utHltipUcafa 
in a distinct genus, Spea, which was characterized by the presence of 
a frontoparietal fontanelle. This character is generally constant, al- 
though its inconstancy as a s;>eci(lc character is t> be expected some 
where. The genus Spea is the seat of the failure of this generic char 
acter to coincide with the other detinitions of a species. In one of the 
four specimens of the subspecies Intermontanus 1 find the fontanelle 
present, while in three it is absent. In a fifth specimen it is rei)re- 
sented by a fissure between the frontoparietal bones. 

The S. h. bombifronn appears to be, at first examination, a well de- 
lined species, The interorbital protuberance is a striking character.

I took a specimen of this si)ecies within the limits of Salt liake City, 
and subseipiently obtaiiu'd tiiree or f(Uir sju'cimeus from Pyramid Lake, 
Nevada. The sides and much of thiMbusal re<;ionarecovered with rather 
larnc lidu'rcles closely jdaccd. The frontoparietal bones, though ossi- 
fied, ate not ronjiliencd, as in the species of Scaphiopus. It is nearest 
the S. coH('/(// (from near San Antonio, Tex), in that si)ecies the vo 
luerine teeth are entiiely posterior to the internal nares; in this (uie 
they are between the fiosterior bordi'rs of the same. The lips arc^ not 
cross barred, as in the A', couch ii ; and the superior rejiion has two 
pale lines on each side. In *S'. coiicliil these lines are replaced by a 
coarse, uuirblinf;'. As compared with the Sj)(<( IkdiuiioikIH, this froj; 
differs in its lar';er size, lighter colors, and the presence of the superior

I found it associated with Biifo coUonbicitsis in a pond near tlu^ shore

The range of this species is extensive. It was originally obtained 
near lledding in noithern California. .My friend, James S. Lipi)iiic()tt, 
has sent it to nie from the extreme sonth of California, San Diego. The 
Smithsonian Institntion has a slightly ditterentiated variety from Chi- 
huahna, and specimens from my frieinl, Dr. Dng(5s, from (Inanajiiato, 
IMexico, are the same. I snsjject that the SraphiopuH (hu/cNi Uroechi 
from that locality is the same species. 

Abnndant in Jnly and August, when it deposits its eggs in the pools 
of rain-water. It is very noisy at such times, and the open lots in thi^ 
city of Santa Fe resound with its cries. These are much like those of

The specimen 9943, from the Yellowstone Kiver, is an excellent illus- 
tration of the mode of origin of corneous ei)idermis. The end of the 
muzzle and the frontal convexi*^y are covered with a layer of black 
horn, each forming an oval shield, wliicli meets the other on the top of 
the snout. This is probably a result of the constant jiressure anl fric- 
tion of the earth when the animal is burrowing in it. Althoii„(i the 
aninial burrows with the hinder limbs, the muzzle is naturally used in 
keeping the passageway open to the surface. Tlie character is not con- 
stant. 

This species is characteristic of the northern parts of the plains and 
Great Basin. I found it especially common in tiie region north of the 
Missouri Kiver and eastward of Fort Benton. Before my arrival there 
rain had fallen, and the ruts of the wagon-trails were tilled with water. 
These ditches contained numerous examples of this species, together 
with Cliorophiliis Irisrriatus, Ilufo coiinatHs, and AmbUjHtoma tigrlmtm. 
Their metainor|)hosis was completed by that time (August 20), although 
some of the specimens were small. 

In Idaho, near latitude 4.5^ 30', is situated a body of water known as 
Market Lake. Its extent is variable, for it is said to be dependent for 
its water supi)ly on the overflows of the Snake Kiver, which is a few 
miles distant to the eastward. An old channel leads from the river to 
the lake, giving probability to the statement. , At the time of my pas- 
sage through the region the water was unusually high, for a portion of 
the stage road, with parts of numerous telegraph poles, was submerged. 
The lake appeared to be about ten miles long by six in width. The 
country surrounding it is arid, and the sand, which represents soil, rests

ou a basis of lava. The stage halted for a short time to enable me to 
examine the shore of the lake. I found it to be lined with a windrow 
of sri^sahoitiK'vs (Culoptcnus mmtus) wliieh had fallen into the water 
and been washed up, some living, others dead. Among them 1 found 
numerous large fat larvie of S2)ea bombiJ'ronn oecupjing small spaces 
whieh they had cleared, quite out of the reach of the water. Their 
limbs were nearly fully grown, while their tails hadsuflered no absorp- 
tion, and their jaws were toothless and cartilaginous ; some quite larval 
in form, others with wider gape. They were engaged in eating the 
grasshopper., and I detected several specimens with the entire insects 
in their mo.Uhs. In some instances the grasshoppers' bodies were too 
large and projected from their mouths. These precocious larva- were 
evidently nir-breathers, and hopi)ed about, presenting a curious ap- 
l)eaiance as they dragged their large tails after them. 1 found some 
adult si>ecimens of AmbUjstonui mavortinm also along the water's edge. 
These observations were made on the llth of August, 1870.

fontanelle and with complete ethmoid arcli, and a styloid osseous xiplii- 
sternum, with termina' "irtilagiuous disk ; tlie auditory organs perfectly 
developed; the lowes 'eveloped ethmoid arch and frontoparietal 

roof, and disciform c. ginous xii)histerimm without style, with 
Eustachian tubes ami memhrauum tympani wanting. Accompanying 
this succession, we have four modiOcations of the family structure to 
adapt to as many modes of life: the aquatic, the terrestrial, the arbo- 
real, ami the subterranean. As the earth's surface is the common 
ntediiim between the above extiemes, so the s])ecies of terrestrial habits 
furnish us with none of the adaptive extremes of structure, but reujiiin 
an intermediate grouj), from which the succession of structures, inter 
rupted, it is true, passes towards the divergent types. Develojuneiiral 
structures accompany and confirm the adaptive, but by no means al- 
ways coincide. 

The aquatic habit is attained when the digits behind iirc not only 
webbed, but when the external metiitarsi are separated by Mu'inbiane 
also; the arboreal, when the terminal phalanges are furnished witli a 
terminal transverse limb, which supi)orts an adhesive disk. Tlse sub 
terranean is shortened, and furnished with a great development of tin' 
lirst digit or prepollex of the tarsus, which is covered by a corneous 
sheath, and serves as a si)ade. The lirst type may be combined with 
the third, as in Mixophyes and Chiroleptes, or either may be furnished 
with a bony overioohng of the temporal muscles, and pciietration of its 
integuments by the hyperossilication of the cranium. 

The fossorial spur is weak in lleliopoius and Paludicola, weaker in 
Mitrolysis, and just represented in Ceratophiys. The palmate foot is 
<liminished in Calyi)tocei>iialus, reduced in Mixophyes and Chirolei»tes, 
and represented by a trace in ll^loriiiiia and Limnoinedusa. The un- 
developed ear is seen in Telmatobius and in Alsodcs. 

Tiie variations in tiie develtti»inent of the tliumb are not so striking 
as in the llylida'. In (inatiiophysa, Cystignathus, and Ceratophrys 
the trapezium sui»ports an osseous metacarpal and obtuse phalange, 
whi(di are concealed ill a large tiiln'icle. In Mixophyes, on the otiier 
hand, the inetacai|)al is slender, cut irely caitiiagiiious, and does not 
support a phalange. Tiiere is no where a spur, as in Ilypsiboas. 

With regard to the deiinal attaciiments, the following inii)ortant 
varieties o(!cur; in the family generally, but especially among Ilylodes 
and ('ystignathi, the dorsolateral septum is placed esi»ecially high up: 

I'seudea. — Se[)ta in Pseiidis as in Ifaiia; in Lysajuis tlu^ laterovenlral 
line is a little widened. In Mi.ropln/cs ftisriohifus the lateroventrals 
are very wide, and leave the ventral free space very narrow behind the 
middle. 

(Jemtophryiks. — In Ceratophrys the lateral septa nvo narrow, and 
there are two posterior abdominal transverse septa, similar <o tliost* 
altiiched to the sternum. In Crrdtophri/s urntUa these are wanting, luit 
the dorsolateral line is veiv broad.

THE IJATUACHZA OF NORTH AMERICA. 311 

Crinkv. — Among these animals I have examined species of IIeliopo« 
rus, Phityph'ctrum, Crinia, IJorboroca'tes, Eiisophus, and IJyperolia, 
and in none cau I lind ni )i'e than lateral traces of the epicoracoid and 
coiacoid septa, excei)t in the Uyperoliti marmorata, where they are coin- 
l)Iete. Tlie posterior abdominal is well developed in JJmso/jZ/us nchu- 
losus. 

i'/eio-orfcmfC.— Ventrolateral low down, and posterior abdominal well 
developed in Vkurodema hihronii. 

i/^iorfcs.— Dorsolateral and ventrolateral far apart; the transverse 
posterior abdominal septum in the species of Lithodytes, in Ephirejcis 
longipes, in Enhydrohms vomerinns (Elosia Girard) and HypotUetj/on ri- 
dens. I hiive not found it in Lithodytes ams2>ivillatus Gthr., Enhydvohim 
parvus., and Limnocharis/uscus Bell {Elosia Mrt.sM.s' Girard). 

Vystignnthi. — In all the species the structure is similar to that of 
JJana, except in the approximation of the dorsolateral lines, aiul the 
l)resence of the postabdominal septum, which is continuous with the 
latoroventrals, and is indicated externally in several of the species by 
a fold in its line of attachment. 

The accompanying table exhibits the allinities of the genera and the 
groups into which they naturally fall. 

This family was first characterized by the autlior in Proceedings Acad- 
emy Natural Sciences, 1803, 1(J; excluding, however, the genera Cera- 
tophrys and Tomopterna; and subsequently more exactly in the Nat- 
ural History lleview, 1805, Several changes, approximations to nature, 
were proposed by me in 1800. lioulenger adopted this family as I dc- 
dedned it (Cat. IJrit. Mas., 1882), but modiiied the extent and definitions 
of the genera materially.

There are then known twenty one Australian species, of whith all 
but two possess an incomplete eranium and none a bony xiphisternal 
style. In the ratagonian snbieyion twenty- four species, of wbieli ten 
exhibit an incomplete cranium, and live a complete bony xiphisternal 
style; in the l>razilian subre-iion sixty-seven species, of which only six 
have an incomplete brain case, and twenty-four the osseous xiphister- 
nal style; .Mexico, thirty-two species with complete cranium, and one of 
these with stylo; the West Indies with twelve, none having' the fonta-

* Approxiinatf. 

In regard to tlie cranial development, the West Indi. region is |)rc- 
eminent in this family, as in the Il.vlid;c; the lirazilian inferior, and the 
.Australian vastly below all; the degradation appearing in a certain 
degree regular. In the lack of vomerine teeth (a feature of immatur- 
ity) South Hrazilian and Argentine forms predominate. In possession 
of the raniform xiphisternum the West Indian and Mexican subregions 
show fewer rej)resentatives ihan the Brazilian. There are none in the 
Australian. 

One si)ecie.s — hilhtnhitcs ricortUi — wanders from the 11, Neotroi»ica 
into the southern projection — Florida— of North America, and two 
others, lAthodytcH lufrans and Sijrrlinjilius maruocliii, have a distribu- 
tion in Southwest Texas; no others are known to o(!cur beyond tlit* 
borders already state«l. No species is connnon to the R. K. Australis 
and Xeotropica, and but one genus — IJorboroca-tes. Two Hrazilian 
spe(!ies occur in the Southern West Indies and two in Southern Mex- 
ico ; probably three of the same country must be included in the iWu'iios 
Ayrean list. 

As yet we are accjuainted with the fo.ssil remains of but one specnes 
of Cystignathidic— a Ceratophrys, from a Ijrazilian cave. It has Iteen

linger is as large as the foroarin and e.vceeds tin' thumb, wliieh in turn 
is considerably lou-ger than the second linger. There are t .vo ,st ion '^ 
palmar tubercles, of which the external is divided into two by a longi 
tudinal groove. There are two solar tubercles, and the entociineiform 
is prominent and obtuse. The muzzle marks a point beyond the mid- 
dle of the tarsna of the e.vteiuled hind limb. The tarsus to thi^ e ito 
cuneiform is just half as long as the remaimler of the foot. There are 
prominent tubercles on the inferior side of the digits of both «'.\trem- 
ities. Tiie head is wide and Hat and tlie loreal region oblicpie. The 
nasal region is Hat and gently <lecnrved and the \\[) projects a little beyiuid

border to the external nostril, whiidi is very near the einl of the muzzle, 
and exceeds the long or vertical diameter of tlie membrannm tympani by 
one-half of the latter. The v.idth of the tynipanic membrane is live- 
sixths of its height. The tongue is subronnd. The ostia pharyngea are 
large, but smaller than the choanie. Tlie vomerine teeth are in two

This species is one of the larger forms of the genus. The nasal bones

Vt'itebni' procaOoiis. Sacral diapopliyses dilated, the simple iirostyle 
articulated to two condyles. External nietacariu bound tof^etlier. Ter- 
minal phalanges articulated inleriovly onto the extremity of the penulti- 
mate, globular or swollen proximally, and giving rise, usually from a cen- 
tral emargination, to the curved, acute distal portion, which is of a more 
compact tissue. Superior plate of ethmoid never covere«l by ironto- 
l»arietals, usually produced anteriorly between frcMitonasals. Ear per- 
fectly developed. Abdominal integument generally areolate. 

Tills family embraces the tree toads of Australia and America. It 
presents comparatively little structural variety, not containing as un- 
developed types as the Cystiguathida', nor as high ones; it poss.esses 
neither earless nor fossorial, nor really acjuatic genera. 

The adaptive modifications are: First, those which accompany a ter- 
restrial habitat, i.e., the diminution of the digital dilatations and palma- 
tiou. These occur in regularly increasing degree in a small nnnd)er of 
the species of the typical genus llyla, and are general in atul distinctive 
of two other genera. Second, those whiiili adapt the extremities to 
grasping a limb by opposition of digits, instead of adhering to a sur- 
face by expansion of them in one plane. This lirst appears possible in 
Agalychnis, and is structural in IMiyllomcdusa. Third, those which re- 
strict the light admitted to the retina, first, by the lateral contractility of 
the pupil; second, by the ren<lering opaqueof the inferior palpelira. The 
lirst characterizes the two genera just mentioned, the last occurs in the 
first two, but is inconstant in the second, and characterizes two other 
genera. Fourth, that which adaj»ts the female dm iug the breeding sea- 
son to localities without water, or where peihap.-i the water (;ontains 
enemies, by the inversion of the dorsal integument so as to lorm a sacli, 
in which the eggs are carried. This occurs in and is accepted as char- 
acteristic of two genera. 

Another feature, which has a functional value, is the union of the 
abdominal integnmenls with the snperlicial fascia of the muscles by 
an areolar or (ibrous network, continuous with that of the usual latero- 
ventral band. The skin of the inferior surfaces of these creatures, as in 
the raiiiform tree frogs, has a thickening in numerous close areola', the 
nature and fun(;tion «)f which is like that of the digital dilatations, and 
Ihevlerm of the tuber on the thumb of the male K'ana, /. <■., to secrete an 
adhesive fiui:l as aid in maintaining the peculiar positions assumed. 
In proportion to the development of these is the extent ol' the abdomi- 
nal attachment, and hence may be supposed to bi' adapted lor reliexing 
the other arcolarconnections from the strain of the animars weight when 
in an ai)pressed or vertical j)osition. Its nnifoiiiiity in the bnriowing 
genera of the liufonida' an<l Scaphiopodida-, and especially on their dor- 
sal surface, rather confirms this view. 

This connection is, however, evidently not necessary to the use of the 



*riatus 7-^ 73.

Willie West Indian species are neiuiy all of <Mie j^enns, tlie Scytopis 
noted beiny the *S'. niher of Siirinain, wliicli occurs in Trinidad. None 
of the species ever i)ass these bounds, with the lastnientioned exct'iition,

In the species of llylidae (joloration may be tlistributed into two 
regions; the (ir-M including that which is exposed to tlie light when the 
animal is crouched, with the limbs all Hexed and close pressed to the 
sides, the hands and feet coniiealed more or less finder the body; and 
the second embraces what is thus hidden from the light, especially the 
jiortions in actual contact in llexure. Any marked dilfereiute in color 
of the different surfaces will usually be found to have reference to this 
division into regions, generally very dissimilar in appearance. This 
is well seen in Jfyhi ((lulerNonii, furolineu.si.s, and in I'hyllomedusa and 
Agalychnis. For convenience of reference, J here, as in otln-r genera 
of IJatrachia iSalieiitia, term the iiortions of the bixly and limbs which 
are exposed to tlie light external: those (!oiicealed in the llexure, in-

Typical coloration : Above, brown or j;ray, with a blackish triangu- 
lar patch boiween the eyes, the ai)ex directed backwards; the bor- 
ders of this aie of a li{;ht color, which is lijjht green in life, and is con- 
tinued as a band to the end of the body. Three dark bars on the lip, 
one from the eye to the anterior UNncr aim across the angle of tlu^ 
mouth, pale bordered above. A dark bar from the orbit across tln^

dark bar from behind the scapular region restricts tli«' doisal line near 
the sacrum, and is usually continued with an interruption to the groin, 
('(dor of upper surfaces continiu>d on a less purt of sarface of femur, 
which is cross-barred; behind this pale, with a longitudinal band or 
series of spots itosteriorly. Throat in spring yellow. 

This species possesses the power of metachrosis oi- color-change in a 
high degree. The dorsal stri|)e and border of the iuterocular spot may 
be bright green, dirty white, or briglit rusty; and the dorsal tidierdes 
vary in color in the same way. The general tint varies from bright 
green to dull slate color. 

In its liabits the Arris f/rjillns is a lover of the muddy borders of the 
water, into which it leaj)s when alarmed. As it does not conceal itself 
among vegetation, like the Ifi/lti pkheriiifiii. it is much nu);''> easily 
caught than that speciies, and is more common in museums, though uot 
less abundant. As the structure (d" the feet indicate, it is a good swim- 
nier, and its i)owers of leai)ing are remaikabh'. 

Tliis species is distributed fr<»m I-Morida to Texas, through Kansas

York. 

The Uv.rthern and southern secstionsof this area i)rodiU!e forms whicU 
olVer considerables dilVereiu'cs, but which must be termed subspecies, on 
account of the existence in some localities of intermediate individuals. 
1 have seen such from Illinois, I'ennsylvania, .Misstuiri, and elsewhere. 

These subspecies are as t'ollows:

Brownish abovo. The iiuMliaii r'j'moii of head and body almvo brijilit 
green; a dark triansh' between llie eyes. Three obli(|ne blotches on 
the side.s, nearly e^inidistant : the lirst belihid the eye, the hist on the 
Hanks and running up on the back ; all usnally margined with liglitrr, 
a narrow wliite linc^ from tlie eye to arm. IJencatli yellowishwiiite. 
Inferior face of thigh i)hiin. Tibia a little more than half the length (»t 
the body. Foot rather smallei'. Head rather obtuse, scarcely longer 
than broad. Web of hind foot extending to the penultimate articula- 
tion of the (ourth toe. 

This subspecies is (tharai^terized by a rather long, narrow head, with 
the eyes farther back than usual. There is no constriction for the neck, 
the outline tapering towards the snout from altout the middle of the 
body. The limbs are very muscular, and c(Misiderably developed. 

The eyes arc large and prominent ; their anterior edges deciidediy be- 
hind the middle of the commi.ssnre, and their posteiior barely anterior 
to the angle of the mouth; hence the siu)nt is consideraldy pr<Mhiced. 
The nostrils are minute, situated on thecanthus rostralis, rather nearer 
t/ie tip of the snout than the eye, and .separated by a distaiu'e less than 
one-third the width of the rami. Tlie tympanum is small, not veiy dis- 
tin(;t, about half the diameter of the «'ye, and placed just above the ric- 
tus. The head is abnost as long as wide, espetiially in laigc specimens. 

The tongue is broad, oval, subtruucate, and but slightly emarginate 
behind; the anterior extremity rounded; it is frcc^ behind and on the 
sides. The inner nares are large, open, i>la(!ed a little in front of a 
point opposite tlu^ anterior canthus orbitalis. 

The vonu'rine teeth are situated in two oval patches about the size 
of the nares, the slightly longer axes inclined a little to each other, 
backward. They an^ phu-ed between the nares, their anterior edges 
nearly in the same transverse line with those of the nares, and extend- 
ing a little beyoiul the nares i)osteri»U'ly, and thus more anterior than in 
any other of the .small llyloids of North Anu'rica. They are about as

fiir apart posteriorly as tlieir anterior extioinities are from the nares. 
Tlie Eustachian apertures very nunute, less than the inner nares. 

The lower parts are covered by a depressed. pavement or granulation, 
extending half way up the side and on the inferior face of the thighs 
In many specimens this appears to be wanting between and anterior to 
the arms. The upper parts generally are provided with rather scat- 
teied pustulations or warty elevations, with numerous pores opeidng 
between and on them; these pustules are most numerous on the sides 
and anteriorly. Some are considerably larger and longitudinal, and 
aj)pear most distinct near the edges of the vertebral vitta. 

The hands are large and well develojjed; ratl'er longer than the fore- 
aru). The tips of the lingers and toes are i)rovided with very slightly 
enlarged, depressed pallets or disks, convex beneath and with a nail- 
like groovi'. 

The outer finger is rather longer than the second, and all appear to 
be connected by a very slight thickened membrane. The inner tinger 
is set at a right-angle with the third and posterior to the I'est. There 
is a soft large tul)ercle at its base, and a still larger opposite to it on 
the other side of the palm, the two with oidy a narrow interval. All the 
arti(!ulations of the fingers and toes have well-developed tubercles be- 
tween them. 

The femur is shorter than the tibia, rather longer than the foot; the 
tibia is more than half the h'ugth of the bo«ly. The two outer meta- 
tarsi are (irmly uuit<'d, the others cleft to the base; the intervals of the 
latter, however, fille«l uft by a well-developed inend)raiu», which exteiuls 
as far as the bases of the disks, and tilling up most of the space between 
the toes, ex<!ept on each side of the longest, where the membrane forms 
a narrow margin on the penultimate joint. The third toe is a little 
longer than the tifth or outer. The (tuneilorm process makes a consid- 
(■raltle promiiuMice, while on the opposite or (»ufer sidi^ of the tarsus 
and foot are three or four small tubercles, at about e<|ual distances, 
the distal one oi)|»osite the cuneiform process and largest. The tul)er- 
cles beneath the articulations are very distinct. There is a rudimentary 
membrane along the e\teri<u' edge of the loot. 

In alcohol the general color al)i)ve is of a dull brown. During life, 
however, an area itoumled by lines extending from the jiostrils and 
div«'rging to the middle of the edge of the upper eyelid, then converg- 
ing to the sacral vertebra, then again widening to the buttocks, is of a 
blight grass green. This is inlerru|»ted l)etween tlu^ eyes by a well- 
delined trianghsof bi'own, lu'arly ecjuilateral, with rather c()ncave sides, 
and its base connecting tiie edges of the upi)er eyelids. A ilusky line 
extends along the canfhus rostralis. The sides of the. face and edges 
of the upper jaw exhibit three or four indistinct scpiare blotches, sepa- 
rated by narrower intervals ; oneor more sometimes better defined than 
tiie rest. A dark broad line extends from the sides of the lower jaw to 
the lower part of the insertion of the arm, an«l another from the posterior

portion of the ovhit to the uj))h'1' edj^e of tlio same insertion ; the two 
are oblique and paralh'l. They are sei)arate(l by a narrow light (even 
white) line, exteiulinf? from the orbit a little behind the lowest part and 
riinninff to tho middle of the insertion of tiie arm. IJehind the arm and 
on the side of the body is a still larj-er blotch, similar and parallel to 
the last mentioned, i'.nd behind this and hi.uher upon the baek still 
another, anteriorly eoverinf>' the loins on each side, and innniiif;' ob- 
liquely baelvwards so as to be parallel to the others. The blotehes of 
this posterior pair are separated by the narrowest |>art of the j;reen 
stripe, which is bounded to a considerable distance by these blot<!hes. 
All the blotches Just descrilted, as well as that >n the lop of tlu^ head, 
are «lark brown, margined by a lijihter aicola, which on t-lu^ sides and 
back is sometimes yellowish in life. The under ])arts aic yellowish- 
white or pun^ white; the throat sometimes bri.uht yellow; souu'times 
closely or si)arsely crowded with dark spots. There aic no w«'ll-de- 
lined darker blotches on the arm ; but the thj^li, lej;', tarsus, and loot 
each exhibit two oi- three transverse ones. The buttocks are yellow- 
ish, with the arms brown, and the posterior and anterior faces, with 
small blotches, some of which are oceasionally continent into an irre<'- 
ular dark line alonji the anterior and ixtsferiiw faces of the thijih. The 
granulation about the buttocks is usually wliit«'. 

A specimen from Hussellville. Ky., has the blotches much snmller 
than usual. 

In a specimen from (Carlisle the last vertebra has the transveise 
apophyses very little dilated, though somewhat enlarged at the ends.

The iris of this subspecies is golden and capable of exctessiviM'ontrac- 
tion. A broad blackish spot o(;cupies it at each end <»f the pupil, and 
a narrow hhw.k line above and below the latter. When the iris is con- 
tracted the])npil is shortly transverse, not linear as in many llyke, and 
the brown sjtots are triangles, their apices inwards. 

Specimens from the lower Mississippi ar«' lre«pH'ntly of <»bscnre colois, 
of rather larger size, and with large tubercles. I have not been able to 
distinguish theuj as foiining a constant subspecies. Mr. IJonlcnger, 
(Catal. JJatr. Sal., Ibit. Mas., ISSli, p. .J.'JT) refers such a specinu'n to a 
"var. bufonia." 

In connection with metachrosis in this species 1 obsei'ved in a speci- 
men lately deau that on the end of the muzzle, ])alpel»ra', canthus r«ts- 
tralis, outer line of humerus, ends of sacral diapophyscs, where tlu> 
derm was in ji state of teusi(»n, that it assumed a bright green hue. 

The note of this species may be exactly imitated by striking two 
marbles together first slowly, then fasti-r and faster, for a succession of

about twenty or tliiity beats. Tlie xnma can uot be heard at a very 
great distance. Like Jlyla picl-eringil, this species in confinement can 
readily be made to producic its note by imitating it, either with tlio 
voice or tlie ehittering- of two pebbles. It keeps on the high grass in 
and around marshy pla<!es, seldom if ever ascending trees or bushes. 
When pursued it leaps with prodigious agility and hides uiuler water.

IJody slender ; head jtointed. Limbs much elongated. Head longer 
tlian wide. Web of hind foot extending only to the third arliculation 
(irom tip) of longest toe. Tibia two-thirds length of body. Foot more 
tliaii half length of body. Colors much as in A. crepifaits, but brighter. 
Inferior surface of thigh plain, or very slightly freckled with darker. 
A narrow white line irom eye to arm and a light line above the urostyle. 

Having presented a minute descri])tion of ^4. crepitans, \t will oidj' be 
necessary here to give the prineii)al points of difference as compared 
witn that si)ecies. The entire form is much more slender, and the limbs 
longer in i)roi)ortion. The head is much more acute, and the outline of 
the lower jaw elliptical, instead of being nearly semicircular. The chord 
of the rami is longer than their greatest Avidth, not e<(ual to it, and the 
(!left extends further back. The tymi)anum in both is scarcely distin- 
guishable. The tongue is large, triangular, and Hesliy. The teeth are 
in two small circidar pat( lies, between the inner nares, and separated by 
quite an inteival. The pallets at the tips of the more elongated fingers 
and toes are very moderate, less prominent than in A. crepitans. The 
fourth or longest toe projects beyond the rest much more than in A. 
crepitans iwnl the web scarcely extends on either side beyond its ante- 
penultimate articulation, while in A. crepitans this web reaches to the 
lienuUimate one and even as Ji very narrow margin to the very tip; nor 
between any of the i)halanges does the membrane extend to the disks as 
in (he other. 

The general distribution of color is the same, although the pattern is 
brighter and clearer. All the blotches have a narrow border of white. 
The posterior large one seems to extend higher up on the back. The up- 
l»er jaw has four narrow white lines i)erpendicular to its edge on each 
side, as in the other species, inclosing nearly equal spaces. There is a 
light streak down the posterior part of the back above the urostyle which 
we have not noticed in the other. The dark longitudinal line on the

posterior Caci^ oftlio tliif-h is more (list iiict. The limbs inv. more lliicly 
biirreil abovt', tliri'o or four lascia' on oac.li Joint; tiie npp'.'r and ontcr 
Hurf'aco ot tlitiliands and ft'ct also (int'ly barred. 

The akin above seems rather smootlu'r than in tiie other, wiiih^ tlie 
throat is more j;ranuhited. 

As ro^'ards tiie transition between this snbspeeies and tiie A.fi. nrpi 
tans, a number of specuniens display intermediate proportions. Tims 
in some the posterior loot, minus tiie tarsus, is exactly hall' the h-nyth 
of the head and body. In some lots from a singh; hxtality some speci- 
mens have th«^ hiud foot one-half the lenj;th, while others fall a litth^ 
below, and still otiiers fall a iitth^ above, this pi'oporlion. Such a lot is 
that from ('ooper County, .Mo., No. .'{rt,"*!. 

The distinctness of the jtosteiior femoral brown stripe is sidvJiM't to 
variation. In typical A. tj. t/rifllitu \t is sharp, and is bordered above 
and below by pale bands, of which the latter is aj;ain bordertMl below 
by a darker shade. In other si)ecimens the lower pale band is shaded, 
and its inferior brown edsie, is indistinct. The infeiior edjic of the 
brown band becomes irrejj[idar, and in the A. tf. rtrjtittnis it is a j^ood 
deal interrupted i»y paler.

ished amount of palmation, but the series appears with onr present 
knowledfi*'! distinct in the strnelnre of the leet. Like the Ijitoiias, its 
lite is passed on the ground, and ehiclly in tiie neighborhood of small 
pools in open and barren situations, whi're the voiei^s of the species 
may be heard with the Acris in the summer, lon^' alter the Ilylas have 
souj^ht their leafy retreats in the W(M»d or fence low. Tliev dill'cr fictm 
the first -mentioned ficnns in belli;;- pooi' swimmers; thonyh they hap 
into the water when alarmed, they do not swim far from the shore, 
and soon return to it. They do not scei;i to be possessed of the power 
of making such i'liormous leaps as the liitorias of Australia, or even 
as our Acris. In typical Kitoria the Inaiii cast* is more elongate ami 
cylindrical and the frontoparietal foutanelh> much narrower, but in 
/y. (niieriniiifi the form and prop')rtiuiis are the same. 

The general form and habits of the Australian ;;eniis (!rinia are not 
very ditlerent from the present; the. terminal, not inferior, attachment 
of the ultimate phalanx will separate it from all llylida'. 

Chorophilns is distiibiited from the I'io (Iraiide, Sail liake N'alley, 
and llocky Mountains on the west, to the Aflanti*!, and IV(hii the (Inlf 
to the northern limits of the Unit<'d States west of tlu^ Alleijhaiiics; 
east of this ran^e I am not awai(^ of its occnnin^- lun'th of middle 
Pennsylvania. Of its six species four are coiiiincd to the (Julf States

The liead is rather short, and the anterior outline is a narrow oval. 
The e.xtreniity of the miiz/le inojects beyond the month, and tln^ lore.s 
are slightly oliliipie ami a little concave. The nostril is but little nearer 
the extremity of the muzzle than the orbit. The vertical diameter of 
the tympanum a little ex«!eeds the transver.se, which is one-half the long 
diameter of the eyeslit. The pupil, as in the other species of this 
genus, is horizontal. The tongue is wide, di.scoid, and entire behind. 
Theo.'^tia pliaryngea are smaller than the small choaiiie. The vomerine 
patches are. short and traiisver.se; they ai«M'ntirely within the lines of 
the inner borders of the choana' and behind the line of the posterior 
boiders of the same. 

The tiiliercles of the superior surfaces are small and lather dcsely 
placed ; they are largest on the sides of th(» back. There is a faint areo- 
latioii of the gular region. The limlis are short and stout. The humerus 
is half or more inclosed in the skin. The |>alm reaches nearly to the end 
of the muzzle. The lingers are short and stout, and have neither dilatii-

the fourth. The palmar tubentles are not distinct. The heel of the ap- 
pressed hind foot in thin specimens marks the middle of the tympanic 
disk or posterior border of orbit, and the end of the muzzle the extremity 
of the tarsus. The hind foot beytuid the tarsus is only as long as the

Dr. Ilolbiook describes the (;(>h)is of this species in lil'e as I'oUows: 

Dove color above, witli oblonj;- spots of darkbiowii, inari;ined with 
yellow. 

The head has a broad, indistinct, triangular spot between the orbits, 
the apex of which is directed backwards. A black liiu> extends Ironi 
the snout to the orbit of the eye, including the nostrils; below this 
black line is a yellowish blotch, covi'riug most of the upper Jaw, The 
lower Jaw is (tinereous above and white below. The i)upil is very dark, 
the iris of a golden color. The. tympanum is very dark (colored, and 
placed in a dar!' vitta, (U' blotch, wlii(!h extends from behind the orbit 
to within a, short distance of the shoulder. The body is of a delicate 
dove-color above, v/itli two or moi'e oblong sjiots of dark brown, mar- 
gined with yellow, on each sule of the vcitebral line; below these, and 
on eacli Hank, are three smaller spots, likewise margined with briglit 
yellow, the anterior one being the largest ; these, with a smaller one 
above the v»'ut, form a triangle on each llatdi; ; s<'veral luiglit yellow 
spots, also disposed ni a triangulai' form, with the api<'es diiccled lor 
wards, aie concealed by the thighs. The inferior surface of tliis ani- 
mal is silver-white, ami ex<;ept (Ui the throat, everywhere granulated ; 
about the throat an' a few indistinct points of black; the anteiior and 
middle parts of the abdomen are white with a slight tinge; the poste 
rior third api)roaches to llesh-color. 

The anterior extremities are dove-<!oI<ue(l abo\e, with a few distinct 
dark bands placed transveisely on the fore-arm, ami a black spot at the 
elbow: a black line runs from the inferior ami upi>er jiart of the shoul- 
der towards the lower Jaw ; dove-coloicd above, with transveise bands 
of dark brown; on the anterior part of the thigh are s^.^ral smiill 
yellow spots; on the posterior surface th(^se spots aie numerous and so 
(thtsely approximated as to icsemble at lirst view a yellow waving liuf. 
Tiie whole under snifacc^ of the thighs is tlesh-coloied ; the inleritu- 
surliuu! of the legs is also tlesh-colore<l, with a I'vw yellow dots.

Proportions rather slender and {graceful. Head rather acute; no 
perceptible contraction at the neck ; li'.i;s lon^' and much developed. 

The nostiils aie situated very near the tip of the snout (the sides of 
which are rather abrupt); they are separated from each other by less 
than on«'third the width of the head. The eyes:ii'e moderate, the rym- 
])anum snudi, about half the dianu'ter (»f the oH.M. A jiroove passes 
from the iiosterior portion of orbit above and around the tym]>anum to 
the in.sertion of the arm in front. Anteritu- marj>iu of the eyes about

the orbit. The vomerine protuberances are in t wo«'lliptical patches, their 
htUfier axes in the .sanu transverse line: their anterior ed;;es just behind 
the losterior border of the rutstrils; the two separated by a narrow in- 
terval. One speciuu'ii has tlu' patches more elonjiated, and narrower 
than the two others. 

The head isslijihtly shorter than broad. The fore;iriii is lonjicr than

Tbe n|)p(.r parts appear entirely sinootii, except an occasional and iso- 
lated pnstule on the side of the back. 

The general color above is of a light chestnut, with blotches of dark 
chestnnt; beneath, reddish-white. A dark chestnut line extends from 
the siiout through the nostril to the anterior canthus, and re-appears be- 
hind the eye in an oval patch, involving the whole tympanum, and ex- 
tending above tiie shoulder. A second similar patcli appears on the 
side, separated from the lirst by about the thickness of the arm. IJe- 
hind this again, and a little more on the back, is a smaller blotch, be- 
hitul which is one still smaller, and the region of the anus is tinged 
with the same color; there thus apitears to be a chain of these blotches, 
extending, at about ecpial distances, from the anus to the eye, the two 
last-mentioned lateral ones fully visible from above. There are indis- 
tinct indications of darker blotches on the back, an<l sulVusious of the 
same round the scattered ]»ustules referred to. The extreme edge of the 
upper Jaw is dark, but between this and the upper stripe, involving 
nearly the whole side of the face below the eye, is an area of light eldest- 
nut, becoming clearer and brighter under the eye. A chestnut stripe 
extends from the lower Jaw up the arm, which has, besides, two or three 
transverse blotches; the femur, tibia and tarsus have each two or three 
transverse fascia-. The anterior face of the thighs is light tliestnut; 
the buttocks the same, with indistiiuit blotches of lighter, in some 
specimens the ground color is greenish lead color.

The length of the head to the posterior margin of the membranum

Tlie head it.self is narrow and acuminate, tiie muz/.lo projecting acutely 
beyond the labial margin. Theexternal nares niiuk two-tifths the di.s 
tanee from the end of tlie muzzle to tiie orbital border. The mem- 
branum tympani is only one fourth the diameter of the orbit. The 
eanthus rost rails is disi iiiet , but obtusely rounded. The vomerine fascic- 
uli are api)roxiinated, and near the line of the posterior border of the 
mires, which are larger than the minute ostia pharyngea. The tongue 
is large and wide behind, and faintly emai'ginate. 

The heel of the extended hind leg extends to between the orbit and 
nostril; the femur is short, while the tarsus is long, a little exceeding 
half the length of the tibia, and etinaling thi' length of the remaimler 
of the foot, minus the longest toe. The skin of the gular and .sternal 
region is smooth, of the abdomen areolate. That of the dorsal region 
is tubercular, smootli warts of large and small size being irregularly 
crowded over its entire surface, and not at all resembling the areolate 
surface of the belly.

This species is rare in collections and has not been well identified, 
owing to the imperfection of Dr. Ilolbrook's description. It can be lu'st 
recognized from Le Conte's description above cpioted. It is an evident 
ally of C. triseriatus. 

A small form is found in Florida, which I have descril)ed under the 
name of Chorophilus rerrticosus. It differs somewhat liorn the typical 
Nigricans, and I suspect that it will turn out to Ix^ a siibsjK'cies. It 
dilfers, besides its very small size, in the somewhat loliger tarsus, wliieii 
exceeds the foot minus the fourth toe, in length. Tlu' yellow stripe on 
the upper lip is broken up into a series of spots. The measurements

This species is not unlike a jounjj Hyla remicnlor in the short and 
rather squat form. Tiie head is more pointed, liowever, the curve of the 
mouth being parabolic rather than circular. The outline of the head 
above exhibits an acute angle, with but a very .slight curve to near the 
nostrils. The sidesof the head arequite oblique, and the direct distance 
between the two anterior canthi, as measurcil witii the dividers, is just 
half that between the two extremities of the lower jaw, measured in a 
similar manner. The upi)ei' Jaw i)rqject.>< con.sidorably over the under; 
po much so that the nostrils are about directly over the end of the lat- 
ter. Tiie extreme distance between the rami of the lower Jaw is the 
same witii tiiat from the ends of the.se rami to the tip of the snout, thus 
forming of the three lines an equilateral triangle. The tympanum is 
(|uite diminutive, scarcely more than half the diameter of the eye; cer- 
taiidy not over half the straight edge of the eyelids. In the females 
it is still smaller. Its center is .situated directly over the angle of 
the mouth or the rictus. 

The tongue is large, thin at the edges; about one fifth longer than 
broa«l, and cordiform beliiinl, with the .sides but .slightly curved; free 
behind for about one-third its length. The posterior nare.s are nearly 
circular and opposite a point half- way betwi-en tiie anterior (tanthus of 
the eye and the outer nostril. The vomerine teeth aie in two oval 
patches, their axes inclined backward.s at less than a right angle, the 
anterior extremities (commencing Just inside the posterior nares and on 
a line with their centers. 

The males are provided with a very prominent gular pouch, capable 
of considerable intlation. 

The eyes arc of moderate size, being a little more than one-third the 
distance from the angle of the mouth to the tip of the .snout. 

The limbs are of motb'rate <leveIoi»ment ; the fore-arm being less than 
the hand. The arm from the elbow is exactly the length of the hind 
foot, nieasured from the end of the tarsus. The femur and tibia are 
equal and just half the length of the body. Closely pressed along the 
sides, the tips of the hind toes extend nearly to the tympanum. The

toes are all aoproased, rather sharp alonff the edges, slender, with par 
allel sides, and not fringed. All are terminated by slight knobs, not 
pallets, bnt little if any wider than the fingers, and very faint traees 
of the marginal nail like groove. The hands are not webbed, except a 
very slight basal web between the three (mter fingers. The toes have 
their bases very slightly webbed, tiie nuMnl)rane tilling np the spaces 
between the metatarsals of the two onter toes. The tnbercle at the 
base of the inner toe rather large; the one opposite at base of outer 
toe, small. Prominent tubercles beneath all the articulations. Verto- 
bric nine, in addition to the coccyx. 

Tiie entire body is stron ,\v and coarsely granulated, conspicuously 
below, where it extends over the chin, between the arms, and on the 
arm nearly to the elbow joint; in fact, no part is free from the granula- 
tion, excei)t perhaps t])e sides of the head. The upper and under faces 
of the thighs are also similarly granulated. 

In the males the up|)er parts are i)urplish-l)rown (greenish-brown 
in life) with dark slate brown markings; beneath cream <Mlor. Tliere 
is a triangular patch between the eyes, the base exti'uding directly 
across, the apex pointing down the back, the sides concave. In front of 
this, in the axis of the head and between the nostrils, is a small longi- 
tudinal streak. A Oiirk pat(!h commences on the side of the snout and 
extends backwards on the side of the head, including the tympanum, 
and, widening on the sides, fades out near the groin ; the upper margin 
of this is most distinctly delined. The extreme margin of the upper 
jaw is dark jnottled, but just above it and below the lateral vitta is a 
narrow line of yellowish-white, w'licli widens after passing below the 
tympanum and, crossing above the shoulder, runs into the light color 
of the under i)arts, completely isolating the fore leg. In the male the 
chin is mottled black ; and in all there is a narrow, indistinct streak of 
brown extending from the lower jaw to the outer surface of the arm, con- 
tinuous with the ground co'or then'. On each si(h' of the bac^k extends 
a distinct stripe. IVom lu'ar the tymjianum to about o|)posite the ter- 
mination of the lateral stripes. An additioinil stripe is seen down the 
middle of the back, scarcely commeneing so far forward; the three 
stripes !' .irly parallel, though with a tendency in the outer ones to 
diverge i>o.-.teriorIy. These stripes are sometimes irreguhir in outline, 
the central one sometimes broken up into blotches, the «'xterior ones 
less fre(iuently. Sometinu's scattered blotches are seen between the 
Stripes. The upper surfaces of tiielimbsare indistinctly bande«l trans- 
versely, sometimes only blotched confusedly ; the posterior faces of the 
buttocks are brown, with (nrcular whitish spots on th" apices of the 
granulation. The inner faces of the limbs are nn(H)l(U'e<l. 

In some specimens, which aitjiear to be principally females, the ground 
color above is fawn, sonu^times light bluish-gray ; and, as already re- 
marked, the longitudinal stripes are occasionally broken up into coarse

A specimen taken by me in Trough Creek Valk'y, Ilinitingdon 
County, Pa., has broad uninterrupted baiid.s. as in the ('. tri.^eriatus 
hut lias not its median muzzle band. The voice of this animal was sim- 
ilar to that of the latter species. 

A specimen of nearly tlie size and form (>f Ifyla fctniiralin was taken 
in west Penn.sylvania, near the Kiskiminitas Kiver. In proportions it 
does not difter from the Feriarum, but tlie toes are fringed, the dilata- 
tions larger, and the coloration different. Above blackisliash, abruptly 
deUned on the sides. Lateral band not extendinj; beyond tympaimiii. 
No median dorsal bainl, but two black dorsolaterals oi' doul)le ordi- 
nary width converge from each tympanum and extend to end of urostyle 
inclosing with the interorbital triangle a narrow, anteriorly bilinrate 
dorsal band of the ground ('i»lor. The note of tliis si)eeies is (piite dif- 
ferent from that of the <\ tri.seriatiis, not being continuous, but in sets of 
crepitations repeated in time and at intervals. 

This variety may not 1m' more allied to the Feriarum than to the others, 
and may be called C. feriarum brachyiihonm.

lu general sliaite this .specie.s is more eloiifj^ated and less squat than 
H. fcriarum, and the hind le^^s are materially shorter. The head is eon- 
siderably more pointed. The nostriLs, beinji a little more in advance 
than in Feriarnm, are still over the end of the lower jaw, although tiio 
projection of the upper jaw is greater than in the latter. The distance 
between the anterior eanthi of the orbits is more tlian half that between 
the rami, and this latter distance less than the ciiord of either ramus. 
The tympanum is small, less than half the diameter of the eye ; iis an- 
terior border on a line with the angle of the month. 

The granulation of this species is very distinct, e.\tending over the 
whole body, except on the interior faces of the hind legs. Jt is most 
couspicuous and distinct beneath, and is seen on the under face of the 
arms, especially evident in the palms of thehamls. 

The tongue is rather thinner than usual in Feriarnm and free for a 
greater distance behind, less emarginated posteriorly. The inner nares 
are circular and nearer the anterior eanthus orbitaiis than the external 
uostril. The vomerine teeth are considerably within and behind the 
ceuters of the posterior nares. The eyes about as in Feriarnm. 

The forearm is a little longer than the hand. The arm from the 
elbow is not so long as the hind foot. In general, while the thigh, leg, 
aud tarsus are shoiter in proportion, the foot is as long as or even longer 
tbau iu Feriarnm. Tlie leg and thigh are nearly of thesame length, ami 
about two-fifths the length of the body. When tlie hind leg is Hexed and 
applied along the sides, the tips of the toes reach only to the axilla-. 
The lingers and toes are much as in 11. J'cr'mrmn, though with all the 
limbs, more slender. 

The ground color above and on the sides is of a light ash, in most 
specimens striped with brown; beneath yellowish-white, with a few 
scattered brownish dots on the sides and sometimes extending across 
the breast behind the arm.s. There is no tiansvcrsc band between the 
eyes, but, instead, an oval spot above each orbit, and between the.se a 
distinct stripe starting between the nostrils and extending backwiir.ls 
to about the mitldle of the back, where it bit'iircates at a very acute 
angle ami continues, margining the iirostyie, as it were, to near the anus. 
On each side of this d(nsal mark is a stripe of similar width, starting 
in a line with the orbital bhttclies, but behind them and extending 
nearly to the groin, having a slight curve outwards to retain i)arallelism 
with the dorsal fork. A well-delincd stripe starts at the snout and 
passes backwards turough the eyes and tympanum over the shoulder

and (lovrn the aides to a point opposite the end of the stripe Just de- 
scribed and parallel to it; in fact, we may distingnish anteriorly five 
distinct dark stripes, and posteriorly six, all abont tiie same size, at 
the same distance apart, and parallel to each other. The extri'me margin 
of the npper Jaw is brown, bnt between it and the facial strijie is a 
narrow, well-defined line of white extending nnder the tympanum across 
the shoulder to be lost on the side. The marginal dark marking on the 
upper jaw is continued across the angle of the mouth (witli a sliglit in- 
terruption over the canthus) up the arm, in a narrow line. Tlie legs 
are all irregularly nmrked with rounded dark blotches, not fasciated ; 
the buttocks brown, with whitish spots on the granulations. 

Some specimens are much darker than the one Just described, and 
occasionally there is a tendency to irregularity in the outlines of the 
stripes, almost breaking them up into spots, in which, however, tiie 
serial arrangement is always evident. Sometimes, too, tlie edges of the 
stripes are deeper colored than the middle.

The {granulation on tlio lower parts seems finer. The ground color is 
darker, though the i)attern in much the same. The dorsal stripe does 
not bifurcate so soon, however ; there is a tendency to spots between 
the stripes, and there are no spots on the breast.

The Choroj)hilus triscriatus abounds throughout the northwest, east 
of the Kocky Mountains. 

1 obtained it at Franklin, on the Utah-Idaho boundary, and sub- 
sequently found it very common in the ruts of the wa,(on trails on the 
plains east of Fort Benton, Mont. In the latter locality it was gener- 
ally of a bright green color. 

Specimens from Gloucester County, New Jersey, present the following 
characters: 

Body longer; head contained three and two-thirds times in total 
length, the widtii three to three and one-half in same; tibia measuring 
half the distance from vent to middle and anterior border of orbit; 
smaller tympanum; teeth nearer each other than to nares; five longi- 
tudinal bands. 

In this form the limbs are rather stout, with their upper surfaces 
granulated or rugulose. Toes fr
