Table as on p. 212. 



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 T. septentrionalis and 

 from T. sexlineatus , although occupying a somewhat intermediate position between 

 the two as regards form and lepidosis. 



8. Tachydromus sauteri, Van Denb.
