Variation . — In the collections studied there are four groups 
of specimens; from Polillo; from southern Sulu Archipelago; 
from Zamboanga, Mindanao ; and from Bunawan, Agusan. These 
may be separated easily, as they all differ from each other more 
or less. 
The Polillo specimens (in alcohol) are lighter brown above, 
showing two yellowish brown stripes from eye to end of body. 
The stripes on the legs are distinct, l^ut the temporal spot is 
sometimes dim or wanting; behind the V-shaped mark the large 
granules, or tubercles, are arranged roughly in two parallel 
rows, which continue backward to end of body. The skin folds 
on inner fingers are distinct ; the enlarged teeth are prominent in 
males and females ; eggs in the belly of females measure 2 milli- 
meters in length. The large teeth in the lower jaw are dim or 
wanting in individuals of the size of Boettger’s type specimens, 
28 millimeters.^® 
The Mindanao specimens resemble the Polillo forms; many 
of them, however, have the anterior part of the head yellowish 
brown in front of the transverse blackish line, and many have 
the belly spotted brown. The webbing of the feet and the pro- 
portionate length of the digits are exactly the same as in the 
Polillo specimens. 
The specimens from the islands about the southern end of Tawi- 
tawi are very dark, almost slatish black above, the band scarcely 
distinguishable from the body color; the anterior part of head 
is lighter; the web between toes reaches to second tubercle of 
fourth toe, leaving three joints free; the membranes fail to reach 
disks, save as very narrow skin folds; the skin fold on fifth toe 
is slightly narrower ; the first finger is longer than second by half 
the length of disk, and the skin fold on inner fingers is less 
distinct; the inverted V-shaped fold is present, but the double 
row of pustules behind is wanting. 
Remarks . — The type was collected by Jose Quadras and the 
locality given is “Island of Leyte.” The species is known also 
from Polillo, Mindanao, Tawitawi, Bongao, and Papahag, in the 
Philippines. Boulenger reports the species from several local- 
ities in Celebes, and from Sandakan, North Borneo. 
Specimens are found invariably in the immediate neighborhood 
of water, usually along streams. I have not been able to recog- 
nize their tadpoles. 
“ Boettger does not mention this character in his description, nor does 
Boulenger in his notes.
