Description—Rostral separated from internasal by anterior nasals; 
nostril between anterior and posterior nasals; two loreals, posterior larger, 
separated from the anterior large supraocular by a small plate; two large 
supraoculars, in contact with frontal, anterior in contact with first super- 
ciliary, other superciliaries separated by a row of granules; six supra- 
labials, fifth very large, under eye; temporals moderate, keeled; three pairs 
of postmentals; back with three rows of large keeled scales on each side, 
separated by smaller keeled scales, which are in two rows anteriorly—one 
row on the middle of the back—and none posteriorly; laterals granular 
except three rows of keeled scales above the ventrals; ventrals strongly 
keeled, in eight longitudinal and twenty-eight transverse rows; preanal 
single, large, smooth, with two smaller plates on each side; one inguinal 
pore on each side; limbs moderate, the hind leg carried forward reaches 
the shoulder; tail about three and two-thirds times as long as head and 
body, covered with strongly carinate scales. 
The color above is brownish olive becoming lighter yellowish brown 
on the head, tail, and limbs. The large dorsals are marked with dark 
brown, which in places forms narrow dark lines along the keels of the 
scales. A light greenish white line starts at the superciliaries, runs along 
the upper half of the outer and lower half of the second row of large 
dorsal scales to the base of the tail. A second light streak starts at the 
nostril, crosses the loreals, the lower eyelid, the lower part of the ear- 
opening, and the side of the body, partly on and partly above the upper 
row of enlarged laterals. It is bordered above by a narrow black line 
from the nostril to a point above the axilla. It passes, in part, below the 
ear-opening. There are black lines on the posterior surfaces of the limbs. 
The lower surfaces are greenish white, becoming yellowish on the tail.

V ariation.—W hat has been said in connection with T. for- 
mosanus need not be repeated here. In the one hundred and 
five specimens at hand the postmentals are in three pairs, except 
in two specimens (Nos. 18488, 18547) in which they are 3-4. 
The inguinal pores are 1-1, except in No. 18360 which has 1-2. 
The anterior supraocular is in contact with the superciliaries 
on both sides in ninety-five specimens, on one side only in one 
specimen, and separated on both sides in nine specimens, includ- 
ing one (No. 25046) of ten specimens from the Pescadores, 
where T. formosanus has not been found. The large ventrals 
are in eight keeled rows, with two or three rows of smaller 
enlarged laterals above them. The large dorsals always are 
in three rows on each side. The small dorsal rows are almost 
always two anteriorly, but almost never more than one, and 
often none, posteriorly. There may be only one small row 
anteriorly. The rostral is separated from the internasal in
