A. FE. Verrilli—The Bermuda Islunds; Coral Reefs. 209 
At present I am able to recognize only 22 Bermuda species of 
true corals (exclusive of the deep-water forms, of which several are 
known.)* They belong to 10 genera, as now classified. 
Quelch, in his report (Voyage Challenger, xvi), gave a longer 
list, for he described, as distinct species, many trivial variations of 
Mussa (as Isophyllia), Meandra, Kavia, and Oculina. But seven 
of the genuine species here described were not known to him, so 
that he really had but 15 genuine species. Doubtless others will 
yet be found on the extensive south-western reefs, which have been 
as yet very little explored by zoologists. 
Some of the common Florida and West Indian speciest that are 
lacking on the reefs here, so far as known, are as follows : 
Mussa angulosa. Phyllangia Americana. 
Meandra clivosa. Solenastrea hyades. 
Meandra (Manicina) areolata. Acropora muricata. 
Dendrogyra cylindrus. Var. cervicornis. 
Colpophyllia gyrosa. “ prolifera. 
Meandrina meandrites. : “ palmata. 
Dichocenia Stokesi. Porites furcata. 
EHusmilia aspera. Agaricia agaricites. 
Cladocora arbuscula. 
On the other hand, certain genera and species seem to be more 
abundant and Juxuriant here than anywhere in the West Indies. 
This is especially the case with the genus Ocvlina, with its several 
species, and with the genus Mussa of the Isophyllia type, of which 
there are here five species and numerous varieties. Agaricia fragilis, 
so common here, is comparatively rare elsewhere. 
It is doubtful if any of the species are really restricted to Ber- 
muda, though a few of the recently described species have not yet 
been recognized from other localities. 
The most conspicuous, largest, and also one of the most common 
of the true reef corals is the brain-coral (MWeandra labyrinthi- 
formis, figs. 71-71c), but on the outer reef the massive Porites (P. 
astreoides, pl. xxix, 1), is quite as abundant, while in some places 
the common star-coral (Siderastrea radians, pl. xxix, 2) is more
