behind; vomerine teeth in two long oblique groups some distance behind 
the choanae, their outer ends not extending beyond the inner borders of 
the choanae; head moderate, without ridges; no apparent subgular pouch; 
nostril much nearer tip of snout than eye, its distance from the eye slightly 
exceeding the diameter of the latter; upper eyelid much narrower than 
interorbital space; tympanum equal to one-half the diameter of the eye, 
its distance from the eye somewhat less than its own diameter; disks of 
fingers large, that of first finger equal to about three-fourths the area of 
the tympanum; first finger shorter than second; toes with a vestige of a 
web at the base; disks of toes moderate, slightly smaller than those of the 
fingers; subarticular tubercles well-developed; apparently a very small 
inner and a still smaller outer metatarsal tubercle; plantar tubercles weak; 
apparently no tarsal fold; the bent limbs being pressed along the sides, 
knee and elbow overlap; the hind limb being adpressed along the sides, the 
tibio-tarsal articulation reaches the posterior corner of the eye; the hind 
limbs being placed vertically to the axis of the body, the heels overlap 
considerably; apparently no series of elongate glands either above the 
tympanum or forming a dorsolateral fold; skin very faintly shagreened 
above; throat and breast smooth; a coarsely granular patch of skin between 
the thighs posteriorly, the granules apparently occurring also in the skin 
of the belly. 
Dimensions. — Tip of snout to vent, 35 mm.; width of head, 15 mm.; tip 
of snout to posterior border of tympanum, 12 mm.; diameter of eye, 4 mm.; 
diameter of tympanum, 2.5 mm.; fore leg from axilla, 21 mm.; hind leg 
from vent, 53 mm.; vent to heel, 32 mm. 
Color {in alcohol). — The ground color has badly bleached and altered, 
due to poor preservation, and appears now as a pale olive-buff. The color 
pattern is very distinct, however, and is unlike that of any other known 
Eleutherodactylus from Hispaniola. A broad pale band between the eyes 
is emphasized posteriorly by a narrow brown irregular line caused by the 
grouping of small brown dots which thickly cover the upper anterior parts 
of the body, the snout and forelegs, less thickly on the posterior parts and 
hind legs. The back of the thighs is strongly marked by very characteristic 
coarsely-reticulated dark brown blotches on a very light background. A 
few similar blotches appear on the front of the thigh and on the sides near 
the groin. The entire lower surface appears to be immaculate olive-buff. 
The sides of the snout and head are thickly peppered with small brown 
dots which are not arranged in any definite pattern. 
Variation. — There are three other specimens of this species (U. S. N. M. 
Nos. 72618-20) with the same data as the type, but in even poorer condi- 
tion. They all show the perfectly distinctive dark blotches on the back 
of the thigh and in the region of the groin. One of these, 72619, shows a 
brown semicircular line bordering the upper part of the tympanum on 
what appears to be a faint glandular ridge. The interocular light band 
may also be plainly seen on this frog. The other two specimens are devoid 
of head markings. 
In 72620, a small individual somewhat less shriveled than the type, the 
disk of the third finger very nearly covers the tympanum. In 72619 only

is the granulation of the belly skin very apparent, the other specimens 
having suffered considerably in the mutilation of this part of the body. 
On none of the paratypes can any longitudinal glands or dorsolateral folds 
be made out, this species evidently being of the smoother skinned ones. 
The paratypes are all smaller than the type, measuring respectively 28, 
29 and 32 mm. from snout to vent. 
Fresh material from the type locality will be needed to confirm some of 
the characters given in the description. In the key, the new form falls 
nearest to auriculatoides, from which it may be readily told by the color 
pattern of the thighs.
