2-3, and 2-2 labials. The number of scales in a row between 
the parietals and backs of thighs is 45, 47 in the Ishigaki 
specimens, and 46, 49, 46, 49, 48 in those from Miyako. In- 
cluding the examples recorded by Stejneger, the scales around 
the middle of the body are 24, 24, 24, 26 in the Ishigaki speci- 
mens; 24, 26, 26, 26, 26, 24, 26, 24 in the Miyako; and 24, 26 
in the Iriomote. The nuchals are 3-3, 2-3, 3-3, 2-2 in those 
from Ishigaki; 2-2, 2-3, 3-3, 2-3, 2-2, 3-3, 2-3 in those from 
Miyako; and 3-3, 3-2, 3-3 in those from Iriomote. All have 
two azygous postmentals except Nos. 21722 and 21723 from 
Miyako, which have only one. All have postnasals except 
Nos. 21719, 21720 and 21722 from Miyako, and one of Stej- 
neger’s from Iriomote, which have none. No. 21719 has the 
anterior azygous postmental divided. The younger specimens 
show a distinct bifurcation of the middorsal line on the head, 
much as in £. elegans. 
Mabuya longicaudata (Hallowell) 
Barbour has called attention to the fact that Fischer’s 
figure of his specimen from “South Formosa” shows dorsal 
scales with only two keels, while Hallowell’s specimen from 
Siam had three. Barbour examined a specimen from Saigon, 
Anam, and another from Mt. Wuchi, Hainan, and found that 
both had dorsal scales with three strong keels. Fischer’s 
specimen has hitherto been the only one known from Formosa. 
The California Academy has received one specimen of this 
lizard captured on Mt. Wuchi, Hainan, by one of Mr. Owston’s 
collectors. This specimen has scales much more strongly 
keeled than any of the Formosan specimens at hand, and has 
dorsal scales with three equally developed keels. The fronto- 
nasal is in contact with the rostral, but is widely separated 
from the frontal by the prefrontals. The supralabials are 
seven, the fifth being much the largest. The eyelid is scaly. 
There is a single azygous postmental and one pair of nuchals. 
There are thirty scales around the body and forty-three from 
the parietals to a line joining the backs of the thighs. The ear- 
openings have three or four small scales projecting from the 
anterior border. The scales under the fourth toe are only 
nineteen or twenty in number.
