oculars in all except one specimen, in which it meets only two 
on each side. The scales under the fourth toe are 18, 18, 18, 
22, 22: and those on the back from the parietals to a line join- 
ing the backs of the thighs are 53, 54, 55, 55, 55. 
Since the scale counts are so constant in this series, while 
Boulenger reports twenty-six rows in his specimens, there can 
be little doubt that more than one form of this lizard occurs 
in China. 
In addition to these specimens from China we have fifteen 
from the Pescadores, nine from Koshun, Formosa, and 
twenty-eight from Maru Yuma, Keelung, San Shi Ka, Taipeh, 
and Tainan, Formosa. ‘These three sets of specimens show 
certain tendencies toward differentiation one from another, 
but these differences are so intangible that it seems best to 
use but one name for all these and also for the Chinese speci- 
mens until the mainland forms are better known. At first, it 
seemed desirable to describe the Koshun specimens as a new 
subspecies because the body is longer, the scales seem smoother, 
the plates under the fourth toe are fewer, and eight of the nine 
specimens have only twenty-four scales around the middle of 
the body. But more than half of these specimens are very 
young and do not show the increase in body-length, and when 
one counts the scales a short distance in front of the middle 
of the body, he may find them twenty-six in number. Fur- 
thermore the coloration seems exactly like that of the specimens 
from the other localities. 
The following notes show the variation and the amount 
of difference in some of the more important characters.
