middorsal line becomes paler and disappears. In the largest 
specimens (snout to anus 64 mm.) the lateral lines have nearly 
or quite disappeared, and the temporal regions and sides of 
the body and neck are’ suffused with brick-red. The ground 
color is black in the smallest specimens, but becomes gradually 
paler until, in the largest, it is a light grayish brown. 
Distribution —This seven-lined skink has been found only 
on Ishigaki shima, where it evidently replaces E. marginatus 
of the northern Loo Choo Islands. 
Remarks.—This species evidently is closely related to E. 
marginatus. It differs in the coloration and in the shape and 
relations of the posterior loreal. From EF. elegans it may be 
readily distinguished by the coloration and the absence of the 
patch of much enlarged scales on the back of the thigh.

Diagnosis.—One azygous postmental; a patch of much 
enlarged scales on back of thigh; no postnasal; posterior 
loreal short, normally touching two labials ; eighteen to twenty- 
two scutes under fourth toe; twenty-six or twenty-eight scales 
around middle of body; fifty-three to fifty-five scales from 
parietal to back of thighs; young with one median and two 
lateral light lines; latter narrow, and separated by not less 
than width of two scales; lower lateral line separated from 
fore limb by less than distance between the lateral lines, and 
running at level of top of hind limb and usually below top 
of ear. 
Five specimens are at hand from an altitude of 1000 to 
1500 feet in Mohkanshan, near Huchou, Chekiang, China, 
not far from Ningpo, the type locality. These specimens all 
have twenty-eight scales around the middle of the body, seven 
supralabials, one azygous postmental, no postnasal, three pairs 
of nuchals, of which two usually are much smaller, and upper 
temporal much larger than lower. The posterior loreal touches 
three labials on one side of the head in one specimen, and two 
in all others. The frontal is in contact with the frontonasal 
in two, separated in three. This plate touches three supra-
