Vor. III] VAN DENBURGH—REPTILES—CHINA, JAPAN, FORMOSA 221 
Distribution—This subspecies is confined to Kikaiga 
shima, the easternmost island of the Loo Choo group. 
Remarks.—Eumeces marginatus kikaigensis is most nearly 
related to E. m. amamiensis. This is what one should expect 
from the relative positions which their islands occupy. It 
differs from the Amami subspecies chiefly in the increased 
number of scales. The snout is probably a little longer, and 
the posterior loreal is more frequently in contact with only 
two labials. It differs from the Okinawa form just as E. m. 
amanuensis does, and also in the increased number of scales. 
Eumeces ishigakiensis Van Denburgh 
Diagnosis—One azygous postmental; no patch of much 
enlarged scales on back of thigh; no postnasal; posterior loreal 
usually rather short, touching either two or three labials; 
seventeen to twenty-one plates under fourth toe; twenty-six 
(rarely twenty-four or twenty-eight) scales around middle 
of body; young with one median and three lateral light lines; 
latter narrow, and upper two separated by less than width of 
two scales; middle lateral line separated from fore limb by not 
less than the distance between the lateral lines, and running 
above the level of top of hind limb and at level of top of ear. 
Type—California Academy of Sciences No. 21666. 
Ishigaki shima, Loo Choo Islands, Japan; May 25-June 2, 1910. 
Description of the type—Similar to E. marginatus, but with an extra 
pair of lateral light lines. Nasal small, in contact with rostral, supranasal, 
and first labial plates. Anterior loreal forming sutures with nasal, supra- 
nasal, frontonasal, prefrontal, posterior loreal, and first and second labial 
plates. Posterior loreal little longer than high, in contact with two labials. 
First labial in contact with rostral, nasal, anterior loreal, and second labial. 
Frontal in contact with frontonasal, and with three supraoculars on each 
side. Parietals large, separated by interparietal. Three pairs of rather 
small nuchals. Upper temporal largest. Seven supralabials, the seventh 
largest. One azygous postmental. Scales smooth, except one behind each 
corner of vent; twenty-six around middle of body; fifty-four in a row 
from parietals to line joining backs of thighs; two middorsal rows not 
enlarged. Median subcaudal row broad. A patch of slightly enlarged 
scales on back of thigh. Twenty scutes under fourth toe. Hind limb 
reaching between wrist and elbow. 
The color above is dark brown, lighter on the head, and at the edges 
of the dorsal, and centers of the lateral and limb scales. A light line 
extends along the middorsal line of body and basal half of tail, bifurcating 
at the parietals as in the other members of the group. An upper lateral 
line starts on the superciliaries and extends to the middle of the tail, being
