III. On the structure of a species of millepora occurring at Tahiti, Society Islands

Abstract

In a paper treating mainly on the structure of the Heliopora cœrulea , which was communicated to the Royal Society in the autumn of last year (1875), I gave a short account of the results at which I had arrived from the examination of two species of Millepora obtained at Bermuda and at the Philippines, and expressed my intention of further prosecuting the subject at the Sandwich Islands and Tahiti, should material be forthcoming. At Honolulu no Millepora was met with; and this form apparently does not occur at the Sandwich Islands, the water being too cold for it. At Tahiti a Millepora is very abundant on the reefs in from one to two feet of water, and is very conspicuous because of its bright yellow colour.
