V ariation.—Fifty specimens have four pairs of postmentals. 
No. 18546 has three on one side and four on the other. No. 
18550 has five pairs. All have but one inguinal pore on each 
side. All have six rows of large, keeled ventrals; usually (44 
specimens) with two, rarely with no, one, or three, rows of 
lateral scales between the ventrals and the lateral granules. 
Fifty-one specimens have three rows of large dorsals on each 
side, separated usually by two rows anteriorly and one row 
posteriorly of smaller dorsals. These small dorsals may be 
2-1-0, 3-2-1, one throughout, or 1-0. One specimen has the 
dorsal scales irregularly arranged, there being about one row 
of large scales on each side, separated by about seven rows of 
smaller scales. The supralabials may be either six or seven in 
number. Forty-one specimens have a single large preanal with 
two keels, three have this plate partially divided, six have it 
completely divided into two keeled scales, one has a single plate 
with four keels. The rostral is separated from the internasal 
in forty-nine specimens, and in contact with this plate in two. 
The tail varies from about three and one-half to nearly four 
times the length from snout to anus. 
The coloring shows very little variation; but one specimen 
from Koshun (No. 18553) has a dark red-brown band along 
the side from the eye, just above the white line, to the tail, 
where it spreads over the upper surface. The white lateral 
line is quite constantly present. 
This species is named for Mr. H. Sauter. It is very distinct 
from any of the known species of Takydromus, but probably is 
most closely related to T. dorsalis.

Diagnosis.—Dorsals large, in regular series; four pairs of 
postmentals; four or five inguinal pores on each side; ventrals 
in six longitudinal rows, the central four rows smooth; head 
elongate; color olive or olive brown above, with dark olive 
brown lateral band; lower surfaces white.

Description of the type—Rostral separated from the internasal by 
anterior nasals; nostril between anterior and posterior nasals (and some-
