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

 larly disposed ; blue beneath. 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 femoral pores. This form seems to 

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

 related to the var. fiumana than to the var. alhiventris. 



The same author (p. 453) finds complete agreement between his 

 specimens of the var. pelagosie and the lizard figured by 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, dass es immerhin misslick 

 ist, zwei in ihrer geographischen Verbreitung durch einen so 

 weiten Zwischenraum getrennte Formen als zusammengehorend zu 

 betrachten." * 



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

 number of specimens from S Nicola, Tremiti Islands, Adriatic Coast 

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

 var. alhiventris from the mainland. 



Particulars of Specimens Examined. 



* In tlie case alluded to (vars. monticola and horvathi) no one has suggested 

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

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