their sluggish natures. When the whistling stopped, the reptilian 
audience retired, and carried, perhaps, the news of the strange 
sounds they had heard to the more domestic turtles which had

No doubt the New Providence guanas were long since exter-

The. Bahama lizards possess the power of changing their colors,

like pouches under their chins, and all are considered harmless,
