NEW. LIZARDS FROM NORTHWESTERN PERU. 

 BY G. KINGSLEY NOBLE. 



The present paper is the tenth to appear deahng with the 

 zoological results of the Harvard Peruvian Expedition of 1916.^ 

 This paper concludes the descriptions of new reptiles secured by 

 the expedition, or at least, those reptiles recognized without 

 doubt as new. No attempt has been made to give a complete 

 list of the species found in the regions visited. Descriptions of 

 the new reptiles have appeared as various groups were studied 

 and compared with related forms from Ecuador and southern 

 Peru. Although this has resulted in a very tardy appearlance of 

 some of the descriptions, the plan has proved satisfactory in 

 most other respects. The region visited was almost unknown 

 herpetologically. This has resulted in the discovery of a large 

 number of new forms. The reptile fauna as a whole exhibits a 

 mixture of affinities, but these cannot be adequately determined 

 until the fauna of southern Ecuador is better known. 



I am indebted to Dr. Thomas Barbour of the Museum of 

 Comparative Zoology for the opportunity of making the collec- 

 tions reported upon in this paper, and for his kindness in permit-
