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. Nor

 related to the white pigment.
