460 Happon—The Actiniaria of Torres Straits. 
CHITONANTHUS, M°M. 
Chondractiniinz, in which the capitulum is provided with longitudinal ridges ; 
the scapus, especially in its upper portion, with strong pointed tubercles, not 
arranged in any definite order, or else with a single circle of coronal tubercles; the 
cuticle strongly developed upon the tubercles; tentacles without any bulbous 
enlargement at the base. 
This new genus has been erected by M*Murrich (1893, p. 189, for Phellia 
pectinata, Hert., 1882, p. 81; ¢f M*Murrich, Proc. U. S. Nat. Mus., 1893, p 190 
(= Phellia spinifera, Hert., 1888, p. 24), and Hormathia Andersoni, Hadd. (Journ. Linn. 
Soc. 1888, p. 251). 
C. pectinata (Hert.); C. Andersoni (Hadd.). 
PARAPHELLIA, Hadd. 
Chondractiniinz, with a smooth capitulum and scapus ; the cuticle is not deve- 
loped; a thin mesoglea; sphincter relatively small. 
This genus was instituted (Trans. R.D.S., 1891, p. 321) for a new species from 
the south-west of Ireland; since then, I have come across two species which appear 
to me to belong to this genus. 
I find that Verrill (“‘ Synopsis of the Polyps and Corals of the North Pacific 
Exploring Expedition,” Proc. Essex Instit., Salem, 1867 (1868), v., p. 326) 
suggests that the form he describes as Phellia inequalis, Verr., n. sp., may be the 
type of anew genus. ‘Should this be thought desirable,” he adds, “I would 
suggest the name Paraphellia. The principal structural peculiarities are the 
extremely short, knotted, outer tentacles; the very narrow, submarginal, naked 
zone; the firm, inseparable epidermis, and the papillose appearance of the upper 
part in contraction. The last two characters are also found in P. gausapata, Gosse.” 
The specimen came from Bonin Island. The tentacles are about forty in number, 
the twenty internal ones are considerably longer than the twenty that compose 
the outer row, the latter are very short and have three constrictions. I must 
leave it to other zoologists to decide whether-Verrill’s proposed name takes prece- 
dence of mine. We have no proof that Verrill’s form is a Sagartid, he states ‘‘ no 
acontia or loop-holes observable.”
