the legs is uniform brownish; the vomerine teeth are in two 
very small, almost transverse, groups, lying largely in front of 
the posterior border of the choanse. 
In the proportions of the legs, the webbing of the toes, and 
the general contour these specimens are almost identical. I 
believe we have to do with only a variable form and not with 
different species; the Bunawan specimens are from a place less 
than 80 kilometers from the type locality. 
Remarks. — The specimens were all found along small mountain 
streams, usually under small plants growing on the rocks. They 
are not uncommon at Bunawan, but are difficult to capture. 
Many other specimens taken were lost before they could be 
studied. The type was collected on Baganga River, Davao, Min- 
danao, by E. A. Mearns.

Description of species. — (From Boulenger.) “Vomerine teeth 
in two oblique groups between, and extending beyond, the pos- 
terior borders of the choanse. Snout much depressed, acutely 
pointed, projecting, longer than the diameter of the orbit; canthus 
rostralis strong; loreal region feebly oblique, grooved; nostril 
nearer the end of the snout than the eye ; interorbital space as 
broad as the upper eyelid; tympanum very distinct, two-thirds 
to three-fourths the diameter of the eye. Fingers long and 
slender, first a little shorter than second, dilated into large disks. 
Toes webbed to the disks of the third and fifth, to the penul- 
timate phalanx of the fourth; disks smaller than those of the 
fingers; subarticular tubercles strong; a small oval inner meta- 
tarsal tubercle. The tibio-tarsal articulation reaches far beyond 
the tip of the snout. Skin smooth ; a feeble narrow dorso-lateral 
glandular fold.” 
Color. — “Greyish or olive above, with or without a light verte- 
bral line ; a blackish canthal streak and temporal spot ; tympanum 
reddish brown ; upper lip with a light, dark edged streak ; limbs 
with dark cross-bands ; whitish beneath, throat and breast some- 
times brown. 
“From snout to vent 58 millim.” 
Remarks. — This little-known species was discovered in the 
highlands of Lepanto, Luzon, by John Whitehead. Four spec- 
imens were taken, female and half grown. It has not been 
rediscovered.
