 America, is dedicated to Mr. George K. Cherrie, the well-known zoolo-

 Costa Rica.

Why Boulenger regards this lizard as identical with the A. undulata 

 is difficult to understand. The differences are numerous, that in the form 

 and size of the gular scales being especially marked. The species was 

 characterized by Hallowell from small individuals ; the present collection 

 contains one (No. 379) which measures (with tail) 205 mm., which equals 

 the types of A. gabbiana.

I have before me fifteen specimens of A. undulata, and find that ten of 

 these have three supraorbital plates and four have four. In none of them 

 are the gular scales so small as in the A. quadrilineata. The specimens 

 are from various localities between middle Vera Cruz and Guatemala in- 

 clusive.
