crater 10 kilometers east of Jolo. These were sitting in 
the edge of the grass about the pool and immediately took 
refuge in the water. The five specimens are all males. (No 
females were seen in this locality.) These were gray white or 
cream yellow above. One specimen showed a triangular black 
mark in the interorbital region and a regular marking on the 
back. In formalin all show dim markings on limbs, and 
three have dim triangular markings on the head; there is only 
a faint suggestion of the white spot in front of the tympanum. 
No. 1704, taken a few kilometers south of Jolo, near Indanan, 
was found under the loosened bark of a tree. In life the spec- 
imen was brownish yellow, and the mark in front of the tym- 
panum was strongly defined; there was a dim line along the 
upper lip with dim bronze markings on sides and throat. There 
is some variation in the relative size of the eye and the length 
of the snout. The males have no vocal sacs. 
One of the specimens taken near Bud Daho was heavily 
infested with small yellow flukes, which were embedded in- 
the muscles of the limbs and the head. More than fifty spec- 
imens of the fluke were taken; they measure, when preserved, 
5 to 6 millimeters in length. Two more specimens of Polype- 
dates linki, a young and an adult, were recently received from 
Jolo, collected by Capt. Francis Link. 
The species is related to Polypedates leucomystax and P. 
macrotis, from which it differs in having a shorter hind 
limb and a narrower interorbital space, in color and markings, 
and in the fact that the skin on the head is not involved 
in the cranial ossification. It may also be related to P. hecticus, 
which is known from Samar, from which it differs in the 
absence of a strongly defined dorsolateral fold. 
The type contains yellow eggs, 3 to 4 millimeters in diameter. 
The stomach contained a full-grown specimen of Hemidactylus 
frenatus. 
Remarks.—The species is named for Capt. Francis Link, 
Philippine Constabulary, who accompanied me on numerous 
collecting trips about the island, and assisted greatly in making 
collections.
