Variation.—The scale rows are thirty-two in two speci- 
mens, thirty-four in forty-nine, thirty-six in thirty, and thirty- 
eight in one. The number of scales between a parietal and a 
line joining the backs of the thighs ranges from sixty-four to 
seventy-eight, the average being seventy-one, and the most 
frequent number seventy-two: 64 in 1 specimen, 65 in 2, 66 in 
A 67ani 1, 68un.9).69 im 870 tah O) 707.172 a 7 oni. 
74 in 10, 75 in 2, 77 in 3, and 78 in 2. All have one azygous 
postmental and two large preanals. The frontal is in contact 
with the frontonasal in all but three of the eighty-two speci- 
mens, and with three of the large supraoculars in all except 
that in three specimens it touches only two on one side of 
the head. 
Distribution —Mr. Barbour has recorded two specimens 
from Bankoro, Central Formosa. The Academy has received 
one from Jenshiko, two from San Shi Ka, and seventy-eight 
from Kanshirei, Formosa, where they were collected in March 
and April 1909. The data at hand are insufficient to enable 
one to judge whether or not the Fokien specimens recorded 
by Dr. Boulenger* belong to this subspecies.

Diagnosis—Ear-opening without projecting lobules ante- 
riorly ; frontonasal broadly in contact with frontal and rostral; 
four large supraoculars, two or three in contact with frontal; 
thirty-eight or forty scales around body; snout elongate; first 
supraocular usually nearly twice as long as second; fronto- 
parietal and interparietal distinct ; no supranasal; lower eyelid 
scaly; a distinct patch of much enlarged scales on back of thigh. 
Type.—California Academy of Sciences No. 18700. 
Koshun, Formosa, March 14, 1909. 
Description of the type.—Snout longer than in S. indicus. Rostral large, 
with a considerable flat superior surface, broadly in contact with fronto- 
nasal. Frontonasal touching anterior loreal, prefrontals and (broadly) 
frontal. No supranasals. Frontal long, narrow behind, in contact with 
anterior two large supraoculars. Four large supraoculars. Frontoparietals 
and interparietal distinct. Parietals short, with a short suture behind small 
interparietal. A pair of small lateral nuchals. Nostril in a single nasal or 
between two nasals. Three loreals; anterior ‘high, in contact with fronto- 
nasal and prefrontal; middle largest. Seven supralabials, fifth and sixth
