to form a huge sac, as has been recorded by Giinther in Cacopus 
globosus of India.*® In this specimen, a female, it would appear 
that the large dorsal skin sac was filled with air or fluid in life. 
It agrees in practically all characters with the specimen de- 
scribed; the color pattern is very dim; the dermal folds on palate 
are identical in arrangement; the denticulation on anterior folds 
is more evident. The specimen is a very large one, by far the 
largest example in the collection. Length, snout to vent, 68 
millimeters; foreleg, 56; hind leg, 96. The locality is Manila.*° 
I have sixteen females and eight males from Mindanao. A 
much larger series was collected, but the specimens were lost. 
The male differs from the female in that the former has a vocal 
sac, the chin is black, and the skin is somewhat distended and 
sometimes in folds; the toes are at least two-thirds webbed, the 
membrane frequently reaching the outer base of digits on first, 
second, and third toes, and the inner base of fifth. At first I 
believed I was dealing with distinct species, but when I found 
them breeding it was obvious that they were males and females. 
A specimen collected by myself in Bubuan Island (Tapian- 
tana Group), Sulu, is much darker, and the typical markings 
on the back are very distinct; there is a hair line from snout 
to vent along the middle of back. 
One specimen, No. 790 E. H. Taylor collection, exhibits a series 
of small, light, dark-edged spots on the back and, especially, 
on the sides; the specimen is somewhat dried, but the webbing 
of the toes seems a little less than in normal specimens. The 
marking on the back is very indistinct. The specimen is from 
Guimaras Island. A Negros specimen has the upper surface 
covered with rough tubercles, and the posterior part of the belly 
granular. 
Remarks.—This species was described from a Luzon specimen, 
but I have been unable to find it in that island. In Mindanao, 
however, it is extremely common at certain seasons. It is known 
to the Manobos as coquat. At Bunawan, Agusan, the breeding 
Season for this frog began November 28, 1912, after a storm 
With heavy rainfall. From the time of my arrival in June to 
that date I had not observed a single specimen. During the night 
of the 27th, a large depressed area in the swamp near the house 
filled with water, and thousands of these toads collected from all

* The specimen was collected by Mrs. Graham, who presented it to the 
Bureau of Science together with certain Philippine snakes (Dryophiops 
philippina). 1 believe there is no doubt as to the locality, although I have 
been unable to verify it,
