erroneous. The pseudo-tentacles [of Lebrunea] have no relationship either in 
position or structure to the fronds of the Phyllactide.’? As MeMurrich has made 
a special study of these forms, and speaks so emphatically on this point, we must 
accept his position for the present. In a later paper (1896, p. 186) he says :— 
“With the two forms already mentioned, it seems that a third should be 
associated, namely, the Hoplophoria coralligens described by H. V. Wilson (1890), 
which, as I have already pointed out elsewhere (1893, p. 133), seems to be 
identical with the Viatrix globulifera described by Duchassaing and Michelotti 
(1860).” Until we have further information on these forms, I cannot accept this 
conclusion ; and I suspect that Lebrunea itself will eventually be ranked under 
the Phyllactidz. For the present, this family consists of two genera only— 
Ophiodiscus, Hertw. 
O. annulatus, Hertw., 1882, p. 57. 
O. sulcatus, Hertw., 1882, p. 61. 
Lebrunea, D. & M. 
L. neglecta, D. & M., 1860, p. 8324; MeM., 1889, p. 33; 1896, p. 186. 
Family.—Bunopipm, Gosse. 
Actiniine adhering to foreign bodies by a flat contractile base ; column 
usually provided with tubercles, or verruce; capitular margin often with 
acrorhagi, which may be complicated; no cinclides ; sphincter muscle endo- 
dermal, strongly circumscribed ; often numerous, perfect mesenteries, all of which 
may be gonophoric, but sometimes the directives are sterile; no acontia. 
Only two members of this family are at present known from Torres Straits. 
The following genera belong to this family :— 
Bunodes. Leiotealia. 
Aulactinia. Urticina (Tealia). 
Ixalactis. ? Gyractis. 
BUNODES, Gosse. 
Bunodide, with the column provided with tubercles arranged in vertical 
series, of which either all reach the base, 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 entacmeeous. At least 
twelve pairs of perfect mesenteries.
