THE HERPETOLOGY OF HISPANIOLA 141 



Relationships. — As I have said under the discussion of semilineaius, 

 that species and olssoni apparently are related to each other more 

 closely than to others of the group of grass lizards having enlarged 

 dorsals. At first glance poncensis of Puerto Rico suggests olssoni in 

 its dorsal and ventral scalation as well as in the style of coloration, but 

 closer examination reveals many differences, among them the regular 

 scaling of the gular fan, which allows none of the gular skin to be seen. 

 Furthermore, poncensis is more sturdily built and attains a greater 

 size than does the Hispaniolan lizard.
