Vou. TI] VAN DENBURGH—REPTILES—CHINA, JAPAN, FORMOSA 219 
has twenty-eight. The frontal touches three supraoculars on 
each side except in three cases, where it is in contact with 
only two on one side of the head. In twenty-five specimens 
the plates under the fourth toe are 17 in one, 18 in three, 19 
in thirteen, 20 in seven, 21 in one. The scales in a row from 
the parietals to a line joining backs of thighs vary from fifty- 
three to fifty-six :—53 in 5 specimens, 54 in 6, 55 in 13 and 
56 in 1. The supralabials are 6-7 in 3 specimens, 7-8 in 2 and 
7-7 in 20. A few specimens have the upper dorsal rows 
slightly enlarged, and a few have somewhat enlarged scales 
on back of thigh, but never as in E, elegans. The young have 
five light lines and blue tails. 
_ Distribution.—This subspecies is known only from Amami 
O shima, Loo Choo Islands, Japan. 
Remarks.—Eumeces marginatus amamiensis is most 
closely related to E. m. kikaigensis, from which it differs as 
indicated under that head. From E. marginatus of Okinawa 
it differs in the fact that the middorsals normally are not 
wider than those of the other rows, in the increased number of 
superciliaries, which normally are nine or ten, instead of eight, 
and in the breadth and position of the upper lateral line, which 
difference seems to be quite constant. 
Eumeces marginatus kikaigensis Van Denburgh 
Diagnosis.—One azygous postmental; no patch of much 
enlarged scales on back of thigh; no postnasal; posterior loreal 
usually long, usually in contact with three supralabials; six- 
teen to twenty-one plates under fourth toe; usually twenty- 
eight (sometimes twenty-six) scales around middle of body; 
young with one median and two lateral light lines, the latter 
narrow and separated by not less than the width of two scales, 
lower lateral line separated from fore limb by less than the dis- 
tance between the lateral lines, and running at about the level 
of top of hind limb but below top of ear; scales of first row 
on each side of middorsal line usually not appreciably wider 
than those of next dorsal rows; superciliaries not less than 
eight; upper lateral line broader, on scales of third and fourth 
rows from middorsal line.
