XIV. — Additions to the Anthozoa and Hydrozoa of the Bermudas. By A. E. Verrill. ANTHOZOA. Madreporaria. A partial list of the corals collected at Bermuda (9 species) was published by J. M, Jones* in 1869. The identifications of his species were mostly made by the present writer, but his collection was very incomplete, and errors wei-e made in printing the list. Another list (10 species) was also prepared by the writer for Prof. J. D. Danaf and published in 1872. Mr. A. HeilprinJ also published a list of the Bermuda corals in 1889. His list included 19 species, of which I consider eight as spurious or mere varieties. The most extended list was prepared by J. J. Quelch for the Narrative of the Voyage of the Challenger (vol. i, pai't i, p. 146, foot note, 1885). This list included 23 species, but several of the six species of Isophyllia admitted by Quelch are scarcely more than individual variations of one species, not even worthy to be called varieties. Probably not more than two actual species of Isophyllia exist at Bermuda, and even these may eventually be united into one very variable species. I could detect no constant differences in the soft parts after a care-ful study of hundreds of living specimens, including all the varieties, though the color varies extremely, ranging through bright green, olive-green, gray, lavender, etc., all these colors being often found on a single example, distributed in regular patterns, or in irregular blotches, and generally they are varied with spots or blotches of flake-white. § In some cases the color may be clear emerald-green, in others nearly clear lavender or gray, but some large examples were found that were half uniform green and half lavender without blotchings, the two colors being defined by a median plane.
