This remarkable species has no particular resemblance to any known 

 species of Amiva or Cnemidophorus. Four specimens. No. 14,710 U. S. 

 National Museum Register, from Swan Island in the Caribbean Sea 

 Collected by Charles Townsend. 



Swan Island is off the northeastern coast of Honduras, at a distance of 

 about two degrees of latitude. It is about five degrees west by south of 

 Jamaica. It was visited by the U. S. Fish Commission steamer Albatross, 

 and Mr. Townsend, the naturalist of the expedition, obtained this species 

 with several others. The present form is related to Amiva as Monoplocus 

 is to Centropyx.
