Takydromus dorsalis Stejneger 
_ The collection includes thirty-one specimens of this very 
distinct species. All are from the type locality, Ishigaki shima, 
in the southern Loo Choo group, to which island this lizard 
seems to be confined. 
These specimens agree so well with Dr. Stejneger’s descrip- 
tion that only a few remarks on variation are necessary. The 
ventrals are in six longitudinal rows in all the specimens, the 
scales of the outer rows being strongly keeled, while those of 
the central rows are smooth in twenty-three specimens, and 
weakly or moderately keeled in eight. All have one large 
smooth preanal. All have four pairs of large chin-shields, 
except one (No. 21183) which has four on one side and five 
on the other. The first pair of chin-shields are partially united 
in No. 21206. The inguinal pores are 2-2 in sixteen specimens, 
2-3 in six, and 3-3 in nine. The superior labials normally are 
six; but ten specimens have them 6-7, one (No. 21187) 5-6, 
and one (No. 21192) 7-7. The rostral is in contact with the 
internasal only in Nos. 21180, 21181, 21200. The color above 
is a bright grass green. The lower surfaces of the limbs and 
tail are yellowish. The other lower surfaces are greenish or 
yellowish white. There are no longitudinal lines except on 
the sides of the head, where there usually is a white or yel- 
lowish band edged above with black. 
This is one of the elongate species of the genus. The largest 
specimens measure 63 mm. from snout to vent with tails 241 
and 232 mm. long. The tails are usually from three to three 
and one-half times the length of the head and body. 
Takydromus septentrionalis Ginther 
Twelve specimens from Mohkansan (altitude 1000 to 1500 
feet) and Hu-chau, Che-kiang, China, are doubtless identical 
with Ginther’s original specimens from Ningpo. They differ 
from the Formosan lizard as stated in discussing T. stejnegert. 
The principal difference in color is that in Chinese specimens 
the greenish blue of the belly often extends up on the sides 
leaving spots of the original brownish ground-color. 
These twelve Chinese specimens all have three postmentals 
and one inguinal pore on each side. All have two rows of
