REPORT OF NATIONAL MUSEUM, 1902. 



The Slippery-backs, as these skinks {Scincidse) are called by the 

 English-speaking people of the Antillean islands because of their 

 smooth, shiny surface, belong to a family of lizards widely distributed 

 over the Tropics of both hemispheres. They are not numerous in 

 America, however, and in the territory we are here dealing with only 

 one species occurs.

 the same as the present species.
