pinkish lavender; two chestnut brown stripes corresponding to 
the dorsolateral glandular folds extend from eye to shoulder; 
limbs barred with chestnut brown; brown spots partially separ- 
ated by yellowish spots on side of head; a yellowish streak from 
eye to angle of jaw; dark marking low on sides and on groins; 
belly flesh-colored; chin and throat with scattered brown spots; 
undersurface of hands and feet purplish.

Variation—Several cotypes from the same immediate local- 
ity agree with the type in general contour but some have the 
color pattern much less distinct; in certain specimens the broad 
dorsal stripe forms three branches posteriorly, one branch end- 
ing at the anus, the others being carried across the groin to 
the femur and tibia. In one specimen, the broad stripe is shaped 
like an hourglass. A single specimen taken near Abung-abung, 
Basilan, agrees very well, save that there is a median yellow 
hair line from snout to anus. 
Some twenty specimens collected on Jolo Island differ mark- 
edly from the Zamboanga forms. The bodies are for the most 
part slenderer, the throats are very dark purple (some almost 
uniform) to halfway on belly. The web is more deeply excised 
between the toes, particularly between the fourth and fifth 
which are less than half webbed. The color patterns on the 
Jolo specimens vary considerably; at least one-fourth have the 
median hair line yellow in color; some specimens are brownish 
above, some gray to lavender. The characteristic marking of 
the type is present in some of the female specimens. 
At first I was inclined to regard the Jolo specimens as a dis- 
tinct species, but as the only tangible difference that held 
throughout the series was the lesser amount of webbing between 
the outer toes, I placed both groups under the same name.
