This species was originally described as Lacerta Uneatus by Linna- 

 eus in the tenth edition of the Systema Naturae, but its name was 

 changed to L. quadHlineata in the twelfth edition of that work. 

 Therefore, as maintained by Andersson (1900), who has examined 

 the type si:)ecimens in addition to the available literature, the form, 

 should be known by the earlier name, or, in modern nomenclature, 

 as Gymnophthahnus Uneatus (Linnaeus). 



Two specimens, U.S.N.M. Nos. 64170-71, collected on the island of 

 Curacao by T. Gaerste, show the following variations : Nasals entire, 

 or with a faint indication of a lower suture; prefrontals in contact; 

 supraoculars 2, the posterior 1 very small; dorsal scales smooth; 15 

 scale rows around the middle of the body; about 35 segments from 

 the occiput to the base of the tail; back with four faint lines; light 

 below; tail salmon.
