Vou. II] VAN DENBURGH—REPTILES—CHINA, JAPAN, FORMOSA 245 
ninety-eight specimens, in contact in seven. The large preanal 
is a single smooth plate in seventy-seven specimens, a large 
plate with two keels in twenty-four, two keeled scales in three, 
and two smooth scales in one. Of forty-seven specimens from 
Formosa examined, the loreal meets the large anterior supra- 
ocular on both sides in two, on one side in three, and not at 
all in forty-one. The supralabials normally are six, but show 
a very strong tendency toward reduction to five. 
The collection contains specimens from Taipeh, San Shi 
Ka, Taihoku, Polisia, Koshun, Tainan, and Takao, Formosa, 
and the Pescadores. Those recorded formerly by mistake 
from Keelung are really 7. formosanus. 
It is with much pleasure that this lizard 1s named for Dr. 
Stejneger, who first recorded it from Formosa, and has given 
an excellent description in his Herpetology of Japan (p. 232). 
Takydromus formosanus Boulenger 
This lizard was first described by Boulenger, in 1894, from 
several specimens collected by Mr. Holst at Taiwan, Formosa. 
Dr. Stejneger was inclined to question its distinctness from a 
series of nine lizards from Taipe, Formosa, which he records 
as Takydromus septentrionalis Gunther, although he thought 
it best to regard them as distinct until further evidence came to 
hand. This view of Dr. Stejneger was certainly a very natural 
one, and Dr. Boulenger deserves much credit for recognizing 
the two forms as distinct, with the limited material which he 
had for study. 
Alcoholic specimens of the two species resemble each other 
so closely in squamation and coloring that, even with more than 
two hundred and eighty specimens, I at first regarded them 
as representing a single species with pores varying from one 
to two in number. It was only upon more critical study that 
the fact that there were two quite distinct species became 
evident. 
There seem to be only three points of value in distinguish- 
ing the two forms. These are the number of pores, the separa- 
tion by granules of the large anterior supraocular and the su- 
perciliary scales, and the position of the dark and light lines 
where they cross the ear-opening. In all other respects the 
two species seem to be alike except that T. formosanus seems
