Vou. II] VAN DENBURGH—REPTILES—CHINA, JAPAN, FORMOSA 251 
but, if a name be merely a convenient handle for certain facts, 
it would seem that convenience might best be subserved by 
regarding the lizard of Miyako as the typical form and the 
northern lizards at subspecies designated by trinomials. I 
think, however, that such separation should await confirma- 
tion of the foregoing results by larger series from Miyako. 
Takydromus sauteri Van Denburgh 
‘This very distinct species is represented in the collection by 
more than fifty specimens from Koshun, Takao, and Kosempo, 
Formosa. The original description (Proc. Cal. Acad. Sci. (4), 
IIT, 1909, p. 50) was based upon a specimen from Koshun. 
Diagnosis.—Dorsals large, in regular series; more than 
three pairs of postmentals ; one inguinal pore on each side; ven- 
trals keeled, in six longitudinal rows; head and tail elongate; 
color above bright green; lateral line on outer row of ventrals 
lower surfaces white. 
Type.—California Academy of Sciences, No. 18001. 
Koshun, Formosa. 
Description of the type-—Rostral separated from the internasal by ante- 
rior nasals; nostril between anterior and posterior nasals, first labial, and 
rostral; two loreals, posterior. larger, separated from the anterior large 
supraocular by a small plate; two large supraoculars in contact with 
frontal, separated from superciliaries by a row of granules; seven supra- 
labials, the sixth largest, under eye; temporals moderate, keeled; the 
internasal, prefrontals, frontal, loreals, and supraoculars have along ‘their 
posterior, and—in the case of the frontal and prefrontals—their ‘lateral 
edges, a row of small tubercles which look like the heads of rivets; 
four pairs of postmentals; back with three or four rows of large keeled 
scales on each side, separated by two pairs of small keeled scales; 
laterals granular, except three rows of small keeled scales just above 
ventrals; ventrals strongly keeled, in six longitudinal and twenty-eight 
transverse rows; preanal single, large, with two keels, and with a much 
smaller keeled scale on each side; one inguinal pore on each side; limbs 
moderate, the hind limb carried forward reaches the elbow; tail about 
three and four-fifths times length of head and body, covered with 
carinate scales. 
The color above is uniform bright green in fresh specimens, becoming 
blue or brown or slate in alcohol. A white line runs along the upper 
lip, passes through the lower corner of the ear-opening and is continued 
along the upper half of the outer row of large ventral plates to the base 
of the tail. The lower surfaces are white, without markings. The limbs 
are yellowish, unicolor.
