Lacerta.

the head and sides, with uumcrous bluish-green ocellar spots irregu- 

 larly disposed ; blue lieneath. The masseteric disc is large, surrounded 

 by rather large scales ; the dorsal and lateral scales are elongate and 

 strongly keeled on the posterior part of the body, and only 3 corre- 

 spond to a ventral plate. 24-25 fenioi-al pores. This form seems to 

 require careful study on a larger material, as it may be more nearly 

 related to the var. finmana than to the var. albiventris. 



The same author (p. 453) finds comph^te agreement between his 

 specimens of the var. pelagosx and the lizard figured l)y Bedriaga as 

 var. latastii, from Ponza, and he therefore unites the two under the 

 latter name. I can see no reason for this course, which seems in con- 

 tradiction with the principle set forth higher up in the same work 

 (p. 409), "Ich selbst . . . glaube aber, dasses immerhin misslifh 

 ist, zwei in ihrer geographischen Verbreitung durch einen so 

 weiten Zwischenrauni getrenute Formen als zusammengehorend zu 

 betrachten." * 



Thanks to M. de Southott", I have been able to examine a large 

 number of specimens from S N'icola, Tremiti Islands, Adriatic Coast 

 of Italy. I can see no reason for separating them, from the typical 

 var. albiventris from the mainland.

* In the case alluded to (vars. monficola and horvathi) no one has suo-o-ested 

 uniting the two forms under one name ; their similarity is to be explained as a 

 case of convergence such as we meet with so frequently in this species.
