Vor. III] VAN DENBURGH—REPTILES—CHINA, JAPAN, FORMOSA 2A: 
in which they are in contact with only two. One specimen 
has but one pair of nuchals, one has one and three; the others 
all have three pairs, of which the first are much the largest. 
The scales around the middle of the body are twenty-six 
except in one specimen, which has twenty-eight. The scales 
in a row from the parietals to a line joining the backs of the 
thighs vary in number from fifty to fifty-seven :—fifty in one 
specimen, fifty-one in one, fifty-three in five, fifty-four in two, 
fifty-five in one, and fifty-seven in one. The scales under the 
fourth toe are sixteen in one specimen, seventeen in one, 
eighteen in three, nineteen in four, and twenty in two. The 
superciliaries are eight or seven. The greater breadth of the 
middorsal rows is nearly constant, being clearly shown by all 
but one specimen. 
Distribution.—Typical Eumeces margimatus seems to be 
confined to Okinawa shima, where it has been taken at Naha 
and Nago. 
Remarks.—This lizard of Okinawa is closely related to 
the subspecies of Amami O shima and Kikaigo shima. and 
less closely to Eumeces ishigakiensis. It differs from all these 
in coloration and in the breadth of the upper rows of dorsal 
scales. 
When Hallowell wrote the original description of this 
species he had specimens from both Amami O shima and 
Okinawa shima. (“Ousima, Japan, and Loo Choo Islands’’). 
There is nothing to indicate either as the type. Stejneger 
has since stated that the Okinawa specimen should be regarded 
as the type, the Amami O shima example having been lost. 
It therefore seems best to regard the Okinawa lizard as the 
typical Ewmeces marginatus. 
Eumeces marginatus amaniensis Van Denburgh 
Diagnosis.—One azygous postmental; no patch of much 
enlarged scales on back of thigh; no postnasal; posterior loreal 
long, usually in contact with three supralabials; 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 two lateral light lines, latter broader but 
separated by not less than width of two scales, lower lateral line
