I. On Cop h Otis sumatrana n. sp. 



The genus CopJiotis was established by Peters for an 

 Agamid from Ceylon and his species , Cophotis ceylanica , 

 must be rare and very locally distributed in that island, 

 according to Giinther. The latter author gives a detailed 

 description and an excellent figure of the animal in his 

 Reptiles of British India. 



A specimen very closely allied to the Ceylon species has 

 been forwarded to our Museum from Sumatra; it differs 

 however in enough important respects from its Ceylonese 

 namesake to permit a specific distinction. In order to 

 facilitate a comparison the points of difference with Co- 

 photis ceylanica are printed in italics.
