﻿stejneger] new species of lizard 295 



Another unexpected character in so southern a species is the 

 number oi submental shields. Four submentals are found normally 

 only in the northern forms such as T. tachydromoides and its allies. 

 The discovery of this novelty in the southern group of the Riukiu 

 archipelago is the more startling, since we have T. smaragdimis 

 from Miyako shima in the same group, a species which conforms 

 in all 'respects to the general typus of the genus, 'hi the other 

 hand, tin.' fact thai we have ten specimens of the present species 

 from [shigaki shima and none of the regular type seems to indicate 

 that the latter may not occur in that island at all.
