Others present variousshades of red, deepening into a rich maroon, alternating withorange and 3^ello\v. The natives of the Bahamas have a wayof preserving these specimens dried, and sell them so cheaplythat, for ordinarv cabinet specimens, it hardly pays the scien-tific collector to take the time to dry them, even if he knowshow to do so successfully.
