the sizes of the dorsal, lateral and ventral scales; forty-five rows may 
be counted between the occiput and a line connecting the groins, and 
twelvein a head length. Between the groin and axilla thirty-five 
scales may be counted to an axillary area of smaller and smooth scales. 
The dorsal and lateral scales are keeled and mucronate ; those of the 
inferior surfaces smooth and mostly feebly notched. Caudal scales 
strongly keeled and mucronate and larger than dorsals. Two parietals 
on each side, the anterior the larger, and extending to the narrow mar- 
ginal supraocular row, so that there is only one frontoparietal on each 
side. A third parietal external to the other two. The frontal is not 
longitudinally divided. There is one series of six large supraoculars, 
separated from the frontals and frontoparietals all round by a series 
of small scales. External to the large supraoculars is a series of four 
much smaller polygonal flat scales much as in S. biseriatus. Between 
these and the superciliaries one row of still smaller scales (with an 
extra scale or two); two scales on the canthus rostralis. Head scales 
all smooth ; six large free auricular scales. A single vertical prehum- 
eral fold enclosing a pocket of granular scales ; temporal scales keeled. 
The extended hind leg reaches to the auricular meatus. Temporal pores 
sixteen ; male with postanal plates. 
Color of adult male dark green above, with faint traces of a paler 
stripe on each side of the back, and of a few darker spots on each side 
of the middle line. Inferior surface dark blue, with a pale line in the 
middle of the abdomen. Femur spotted with blue below; tibia and 
tail light greenish below.
