above may be nearly smooth, or may have numerous warts 
and transverse or longitudinal folds. There are small warts 
on the upper eyelids, especially posteriorly. 
The color above, in alcohol, is brown, gray, or olive, with 
very indefinite darker cloudings on the back and limbs. When 
most clearly marked there seem to be three dark blotches on 
the back behind the head, and three cross-bars on the limbs. 
The upper surfaces of the limbs, the temporal regions, and the 
upper eyelids are sometimes more or less stained with orange 
or brick-red. Individual warts may be reddish or blackish. On 
the hind limbs there often are whitish asperities. 
In these Loo Choo specimens the toes vary a little in length; 
but nevertheless it may be said that they constantly bear the 
relations described by Stejneger. The same proportions are 
seen in a good series of frogs from Formosa which I recorded 
under this name.* None of these Formosan frogs is quite as 
large as some of the specimens from Okinawa. Otherwise, 
upon direct comparison, the two series seem to be absolutely 
alike except in the following particulars: 1. The free dermal 
margin along the outer edge of the fifth toe is considerably 
more extensive in the Okinawa specimens. 2. In these speci- 
mens, also, the web is constantly more extensive than in those’ 
from Formosa. 3. In all the specimens from the Loo Choos 
the dark band which passes through the posterior half of the 
upper eyelids is broad, and is indefinite behind, while in the 
Formosan frogs this band is narrower, is sharply limited 
posteriorly, and has a smaller dark cross-band, blotch, or series 
of spots immediately behind it. 
Since these differences are constant in a considerable series 
of specimens, it is evident that the frogs of Formosa and of 
Okinawa must be regarded as distinct, though very closely 
related, species. The name Rana namiyei must be restricted 
to the Loo Choo frogs, for it was from Okinawa shima that 
Stejneger’s type came. What, then, are the frogs from For- 
mosa? Are they Rana kuhlu or a new species? These ques- 
tions I shall leave for future consideration. 
Rana namiyei has been secured only on Okinawa shima. 
Here it was found in crevices and under the stones of brooks,
