HYLA BISTINCTA Cope. 
Fingers free ; vomerine teeth between nares ; foot shorter than tibia and 
femur ; tympanum one-fifth diameter of eye; vomerine teeth in small fas- 
ciculi ; frontal bones ossified in front; blue, sides pale varied; lip not 
white-bordered. 
Size of Hyla carolinensis. The head, particularly the interorbital region, 
is broad and flat ; the canthus is distinct ; the membranum tympani is exceed- 
ingly small, and is overhung by a thick dermal fold. The skin of the su- 
perior surfaces is smooth. The fore-limbs are very stout, and the animal 
being a male in breeding condition, the thumb bears two coraeous plates 
on the inner side. The larger of these is the inferior, and forms a strong 
prominence on the metacarpal. The surface is composed: of densely 
packed points. The posterior limbs are long, the heel reaching nearly 
to the end of the muzzle. The feet are of moderate proportions, and not 
fully webbed ; the membrane reaches the base of the penultimate phalange 
of the third and fourth digits, and farther on the fifth. 
Length of head and body, .045; of head, .012, width of head at tym- 
pana, .015 ; length of hind leg, .067 ; of hind foot, .031. 
Color, upper surfaces including femur and humerus, dark-bluish plum- 
beous, without marks; inferior surfaces yellow. Sides marbled with the 
two colors; posterior face of femur pale brown, with a few yellow specks 
along the superior border. Eye unspotted. 
Vera Cruz most probably; obtained by Dr. Sumichrast with the H. 
spilomma and H. miotympanum Cope (= H. microtis Peters). 
CHOROPHILUS VERRUCOSUS Cope. 
The length of the head to the posterior margin of the membranum tym- 
pani enters the total length to the vent three and one-sixth times. The 
head itself is narrow and acuminate, the muzzle projecting acutely beyond 
the labial margin. The external nares mark two-fifths the distance from 
the end of the muzzle to the orbital border. The membranum tympani is 
only one-fourth the diameter of the orbit. The canthus rostralis is distinct, 
but obtusely rounded. The vomerine fasciculi are approximated. and near 
the line of the posterior border of the nares, which are larger than the mi- 
nute ostia pharyngea. The tongue is large and wide behind and faintly 
emarginate. , 
The heel of the extended hind leg extends to between the orbit and nos- 
tril: the femur is short, while the tarsus is long, a little exceeding half the 
length of the tibia, and exceeding the length of the remainder 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, smooth 
warts of large and small size being irregularly crowded over its entire sur- 
face, and not at all resembling the arcolate surface of the belly. 
Color above leaden, with three longitudinal rows of darker, light edged 
spots, extending, one on each side, and one on the median line. They are 
each composed of a series of spots joined end to end. Femur and tibia
