No. 1.] ACTINIARIA OF THE BAHAMAS. 23 
Genus BuNOoDES, Gosse. 
Bunodidz with the column provided with tubercles arranged 
in vertical series, of which either all reach the limbus, or only 
those corresponding to the primary tentacles, in which case the 
other series stop at varying distances from the margin according 
to their importance. Margin tuberculate, and forming a more 
or less distinct collar. Tentacles polycyclic and entacmzous. 
Twelve pairs of perfect mesenteries. 
The limitations of this genus have already been indicated. 
4. Bunodes teniatus,n. sp. (Pl. 1., Fig. 4; Pl. IIL, Fig. 7.) 
The single specimen of this species which I obtained was 
found on the under surface of a block of coral rock in the bay 
to the westward of Nassau. The color of the column is olive 
green ; the tubercles with which the column is covered are of 
two different colors, arranged so as to form twenty-four longi- 
tudinal bands. Twelve of these, each containing five vertical 
rows of tubercles, are of the same color as the column, the 
other twelve, each containing three vertical rows of tubercles, 
being more yellowish. The acrorhagi are also yellowish, while 
the tentacles are gray with transverse oval blotches of opaque 
white on their inner surfaces. The disc and peristome are olive 
green. 
The base is strongly adherent and somewhat larger than the 
column, which measured about 3.2 cm. in height in the fresh 
condition, the diameter being about the same; in preserved 
specimens the height is about 1.5 cm. The entire surface of the 
column is covered with tubercles disposed in vertical rows, and 
placed so closely as to allow the general surface of the column 
wall to be seen only with difficulty. There are altogether 96 
rows of these tubercles, all of which extend from the margin, 
which is provided with acrorhagi, to the limbus, and there is 
little, if any, difference in the size of the tubercles in the vari- 
ous rows. In structure the tubercles are markedly different 
from the verrucz which are to be found in Aw/actznza (see below), 
and resemble very closely the acrorhagi. In fact, the figure 
given by the Hertwigs (’79) of the acrorhagi of Avzthea cereus 
would almost answer for a figure of the tubercles of Bunodes, 
except that the nervous layer is not so readily seen in the latter,
