Vou. WI] VAN DENBURGH—REPTILES—CHINA, JAPAN, FORMOSA 205 
ish shading forming a V-shaped mark from top of eye- 
lids backwards. A similar greenish tinge extends backward 
from the sacral region becoming brighter in the groin, where 
it shades off into dull yellow. Tympanum brownish with a 
darker line above. Hind limbs with three faint cross-bars. 
Throat white, abdomen cream. Between the colors of back 
and abdomen there are a few brown spots, increasing poster- 
iorly to form considerable blotches, which are hidden when 
the limbs are folded in the sitting position. This is the bright 
coloration when on a whitish surface. When on a leaf, the 
green spreads to the sides and shoulders. 
No. 23741, also from Ishigaki, in life was brown above 
with darker brown markings; yellowish below; groins straw. 
No. 20087, from Kanshirei, Formosa, while living had 
the abdomen and sides white, thighs greenish straw, the light 
color of back and limbs light golden brown. 
Polypedates japonicus (Hallowell) 
Originally described from Amami O shima and since re- 
ported from Okinawa, this species is now at hand from Ishi- 
gaki and Iriomote, of the Loo Choo group. Boulenger has 
recorded its presence in Formosa and we -have received a 
series from there. Our material comprises one hundred and 
seventy-eight specimens from Amami O shima, thirty-six 
from Nago, Okinawa, sixty-eight from Ishigaki, seven from 
Iriomote, and seven from Formosa. Curiously enough this 
tree-frog was not found in Miyako shima. 
Careful comparison of this enormous material has failed 
to develop any differences between the specimens from the 
various islands of the Loo Choo group. They seem to be quite 
alike in structure, proportions and coloration. The Formosan 
specimens lack the definite dark patch or streak on or above 
the tympanum, having at most a mere trace of it, although it 
is present in all the Loo Choo specimens. In other respects 
these Formosan examples are indistinguishable from the Loo 
Choo frogs, and this difference seems too slight to justify 
their recognition as a distinct subspecies.
