The frontal does not touch the frontonasal. There is one 
azygous postmental. The frontal is in contact with two supra- 
oculars on each side. There are only twelve scutes under each 
fourth toe. 
It is interesting to be able to confirm Boettger’s original 
record of the presence of this lizard on Tsushima. 
x 
Leilopisma laterale formosensis Van Denburgh 
MNagnosis.—Similar to L. laterale but with fewer (53 to 
65) scales in a row on back between parietals and a line joining 
backs of thighs; scales around middle of body usually 28, 
often 26, sometimes 30; dark lateral band without very definite 
lower border; limbs usually overlapping when adpressed; 
frontal usually in contact with frontonasal. 
Type.—California Academy of Sciences No. 25,027. 
Kanshirei, Formosa, Japan, March 20, 1909. 
The nineteen Formosan specimens all have two large pre- 
anals, one azygous postmental, and the frontal in contact with 
two large supraoculars. ‘Two specimens have a small plate 
between the frontal, prefrontals and frontonasal. Three have 
prefrontals meeting between the frontal and frontonasal. In 
the other fourteen the frontal is in contact with the fronto- 
nasal.. In four specimens examined the lamellae under the 
fourth toe vary from fourteen to seventeen. The number of 
scales in a row from the parietals to a line joining the backs 
of the thighs ranges from fifty-three to sixty-five, the most 
frequent number being fifty-six and the average fifty-seven 
and six-tenths. The scales around the middle of the body are 
twenty-six in seven specimens, twenty-eight in eleven, and 
thirty in one. The adpressed limbs in the Formosan specimens 
usually overlap, and when they fail to meet, the distance be- 
tween them never is as great as that between the snout and 
ear. In the other forms the limbs rarely meet. 
From Formosa we have nineteen specimens, one from Jen- 
shiko and the others from Kanshirei. All were collected in 
March, 1909, and some contain eggs which seem ready for 
expulsion.
