A. E, Verrill— The Bermuda Islands; Coral Reefs. 275 
are in four rows, are entirely destitute of the raised transverse white 
ridges or bars, so characteristic of crucifera. Moreover, the smooth 
tapered tentacles are usually fawn-color or orange brown with a 
conspicuous stripe of flake-white on each side, becoming wider at 
base and running inward on the disk as white radial lines or streaks; 
on the outer tentacles the white patches often meet around the outer 
base and extend about half way to the tips. The disk is colored 
like the tentacles, often with an iridescent green tint, variegated 
with brown and lavender and specks of white, and with many white 
radial lines. 
The tubercles of the disk are small and very numerous in each of 
the larger radial rows ; they are.mostly small and verruciform, but 
some are conical, papilliform, or even slender and clavate. They 
are usually darker than the ground color of the disk, but vary in 
color.

natural size; e, tubercles of disk; a, acrorhagus or larger upper verruca ;

The large verrucz or suckers of the upper part of the column are 
bright red. They remain conspicuous in preserved specimens. 
Although in a former article I described this as a distinct species, 
I have here reduced it to a subspecies or variety, mainly out of 
deference to the opinion of Mr. Duerden, who:claims to have found 
intermediate forms at Jamaica, though it would seem that the two 
characteristic forms are also abundant there, as in Bermuda. 
It is quite possible that though really distinct, they may often 
hybridize, and thus produce intermediate forms, as in the case of 
our two New England starfishes of the genus Asterias, which are 
well known to hybridize where their ranges overlap, as in Vineyard 
Sound. 
In many respects this agrees with the description of Actinia 
osculifera Les., 1817, with which I formerly identified it. The latter
