Habitat. Loo Choo or Riu Kiu Islands: Okinawa, Miyakoshima, Amami, 
Oshima, and Kikaiga. 
According to Van Denburgh, the specimens from Miyakoshima have the ventrals 
in 8 longitudinal series and lack the light lateral streak, whilst those from the 
other islands have the ventrals in 6 series, rarely 8, and the light lateral streak is 
present. 
This is a very sharply defined species, equally remote from 7. septentrionalis and 
from T. sexlineatus, although occupying a somewhat intermediate position between 
the two as regards form and lepidosis. 
8. Tachydromus sauteri, Van Denb. 
Takydromus sautervi, Van Denb. Proc. Calif. Ac. (4) iii. 1909, p. 50, and t.c. 1912, p. 251.
