CATALOGUE OF BATRACHIA AND REPTILIA BROUGHT BY WILL- IAM TAYLOR FROM SAN DIEGO, TEX.

BY E. D.COPE.

(WithPlatexxxvi,Fig.2.)

San

Diego isa

town

situated in Nueces County,southwestern Texas, onthe San DiegoCreek, which is a tributaryof the Nueces River. It is distant about50 miles northwest of Corpus Christi,which ison the Gulf of Mexico.

The

present list includes forty-twospecies,which is

an indication ofconsiderable wealth inthe forms oflifeabovereferred to. In a previous essay u

On

the Zoological Position ofTexas"* Ihave enumerated the Batrachia

and

Reptilia

known

from the State. Spe- cies additional tothatlist are mentioned at the

of this one.

Hypopachuscuneus,sp. nov.

The

genus Hypopachus (Keferstein)

was

described as follows: Got- tingeu Nachrichten, 1867, p. 352; Boulenger, Cat. Batr. Sal. Brit.

Mus.,Ed. ^ii,1882,p.159. It is thus defined:

No

frontoparietal fonta- nels. Frontoparietal

and

frontalbonesin contact,concealing theeth- moid.

No

omosternum.

No

dermoossifications. Terminal phalanges simple.

No

vomerine teeth.

Tongue

simple, oval.

Three species ofthisgenus are known, the H.oxyrrliinus Boul.

and

the H. variolosus Cope, which, with its subspecies inguinale Cope, rangesfrom Costa Rica^to

Guatemala

^BATRACII1A

AND ^REPTILIA FROM

TEXAS.

The

JH. vuncus has thefollowing characters:

Head

^small.

Body

large.

Limbs

short. Muzzlescarcelylongerthan diameterof eye, projecting a little

beyond mouth

border.

A

dermal groove acrosshead at posterior borders of eyelids,

and

one from below posteriorcanthus of eye toshoulder.

Another

across the thorax from the inferior origin of one

humerus

to the other. Skin everywhere smooth.

Tympanic drum

invisible.

When

the anterior limb is extended the end of the forearm reaches the

end

of the muzzle.

The

distalend of the tarsus reaches theanterior base of the humerus, and theend of the second toe reaches theend of the muzzle

when

the hind limbis extended.

The

third linger is rather elongate,

and

the lengths of the fingers are in order, beginning with theshortest, 1-2-4-3, the second and fourth being^equal. In the posterior foot the lengths are,

beginning with the shortest, 1-2-5-3-4, the second and fifth being about equal, and the third a good deal shorter than the fourth.

The

palmartubercles are notvery distinct.

At

the distal

end

of the tarsus there are two large subequal sharp-edged tuberosities.

The

edge of the internal isoblique, that of the external transverse. Distinctsmall tuberclesunderthe articulationsofthe phalanges.

The

femurisalmost entirely inclosed in the integument of the body.

The

tongueislarge,

and

forms anelongate flatellipse.

The

internal nostrils are anterior,

and

area little farther apart than the external nostrils.

The

latterare nearly terminalin position.

The

color is light brown, or grayish-brown, sometimes tinged with olive,

and

thereis generally a pale

median

vertebral line. There is a wide band on each sideof a palertint, extending from theorbittonear the groin, it is sometimes only indicated by a lineof black specks, forming a border above

and

below.

A

^pale^line from eye to frontof humerus.

Numerous

ratherlarge black spotsonthegroin,

and

numerous smaller ones on the posteriorfaceof the femur, between which the coloris often dark red. Small black spotson posterior faces of tibia

and astragalus, anterior edgeof tibia,

and

posterioredge ofhumerus.

Digits with ^a light spot ateach phalangealarticulation. Belly yellowish, with or without a faintcoarsereticulation of a darkercolor.

^Nearly ^allied^to^Sceloporus

^and

Uta.

A

loose fold across the throat formed

by

the conjunction of the prehuuieral folds, as in Ctenosaura, not closely foldednorborderedwith enlargedscales.

Fem-

oral pores; nopreanal pores.

No

dorsal crest.

Tympanic

disk ex- posed.

This genus isintermediate between Sceloporus and Uta.

The

loose dermal neck-fold, like thatof

some

of the larger genera of Iguanidre, is not found in the former.

The

^tightlyadherentcollar of

Uta

might have been developed from a Sceloporusthrough a Lysoptychus.

Char., specif.

—

Integument of side of neck thrown into

numerous

folds.

The

most prominent is continuous with the collar fold,

and

it

sends out

two

folds forwardsto the tympanic meatus.

A

^second fold is concentric with thebase of the

humerus

at its anteriorbase; itssu- periorpartis prominent

and

longitudinal, and continues to thefold in frontof it. Tail round.

The

scalesof the sides are smaller than those of thebelly, whichare smaller than those of the back.

The

latterare rather small, counting seventeen longitudinal rows betweenthe small lateral scales of the scapularregions.

The

keels of the dorsal scalesare in parallellines.

Scalesof thetail subequal, stronglykeeled,except below. Fifteenfem- oral pores.

Two

postanal plates.

Interparietalplate large,subround_; parietals small,subpyriform, one

fifth aslarge as the interparietal. Five or six transverse supraorbital plates,separated from the frontals

by

one

row and

from the supercil- iaries

by two

rowsofscales. Frontal dividedtransversely, the anterior part dividedlongitudinally. These plates arepreceded by two ^platesj

three in transverse relation; two large intemasals sepa-

Sides blackish, the prominent parts of the folds of the neck paler.

Anterior border of meatus auditorius paler.

A

^large ^blue patch on eachside of the bellyextending-fromaxilla to groin,

Thisspecies isabout the sizeofthe Sceloporusconsobrinus. Itseems

to be rare, as Mr. Taylor took only one specimen.
