DESCRIPTION OF AN A:\IEIYA FROM TESTIGOS 

 ISLAND, VENEZUELA 



By Alexander C4. Ruthven 



A specimen of Ameiva, collected on Testigos Island, was 

 recently sent to the writer for study from the Museum of 

 Comparative Zoology. The specimen differs in several char- 

 acters from its nearest relative — A. 'bifroniata Cope. The 

 differences are not great, and only one specimen is at hand, 

 but, since the characters are distinct and the genus has ap- 

 parently not been recorded from the island, it seems proper 

 to describe the form as new. 



Ameiva insulana, new species 



Diagnosis : Ten longitudinal rows of ventral plates ; arrange- 

 ment of head scales as in Ameiva hifrontata; caudal scales 

 straight keeled; enlarged gulars in a band across the throat, 

 last three supraoculars together surrounded by granules; 

 outer toe reaching nearly as far as inner ; brachials and ante- 

 brachials not continuous; postbrachials slightly enlarged; 

 hind leg reaching to the anterior border of the ear. 



Type Specimen: No. 14025, Museum of Comparative Zool- 

 ogy- ; Testigos Island.
