species) be accepted, C. passiflora will be excluded from it. 
The presence of verrucz, which Andres makes of so much 
importance, cannot, it seems to me, be considered a generic 
characteristic, since in the Bahama specimens they are present 
in young individuals, but disappear in the adults. Since, then, 
the Bahama species agrees so closely in other particulars with 
the European form, I have given the definition of the genus so 
as to include forms both with and without verruce. 
Family Bunodidz, Gosse. 
Synon. — Actinines verruqueuses — Milne-Edwards, 1857. 
Bunodidz — Gosse, 1860. 
Cereze — Duchassaing and Michelotti, 1866. 
Bunodine — Verrill, 1868. 
Tealidaee— R. Hertwig, 1882. 
Actininz adhering to foreign bodies by a flat contractile base. 
Column occasionally smooth, but usually provided with tubercles 
either simple or compound. No cinclides. Sphincter muscle is 
strong and circumscribed. Perfect mesenteries usually numer- 
ous, those of the first cycle, with the exception of the directives, 
being gonophoric. No acontia. Tentacles smooth, cylindrical, 
and entacmzeous. 
Gosse, who established this family, Jaid most stress on the 
presence of the tubercles, and this has usually been considered 
the characteristic of the family, though later authors have added 
the character of the absence of acontia, thus excluding from the 
family a single species, Bunodes coronata, which was included 
by Gosse. The true relationships of this form have already 
been referred to. Hertwig’s original objection (’82) to the term 
“ Bunodidz”’ is based upon this error of Gosse, and he has since 
(88) withdrawn his name Tealidz in favor of the older one. 
He was, however, the first to point out the systematic value of 
the well-developed circumscribed sphincter muscle, and to make 
this and the absence of acontia two important characteristics of 
the family, at the same time lessening the excessive importance 
of a tuberculated column by including a genus, Lezotea/ia, in 
which the column wall is smooth. The presence of a large 
number of perfect mesenteries is also an important character- 
istic; but in one genus at least, as I shall show, this feature is 
wanting.
