104 Prof. G. Lindstrém on the 
priety of placing it in the genus Caryophyllia; and Prof. 
Duncan himself seems also now to be vacillating on this 
point, as he (Ann. & Mag. Nat. Hist. Dec. 1883, p. 363) 
says that it is a member of the Caryophyllia “ group” 
which of course is something different from the “ genus” 
Caryophyllia. 
Paracyathus thulensis I did not implicitly propose as a 
synonym, but with a doubt, as plainly shown by the mark of 
interrogation. J admit, however, that it might have been 
better not to have mentioned it at all. 
Leptocyathus Stimpsont, Pourtalés.—There cannot be the 
slightest doubt that my specimens are identical with those of 
Pourtalés, who kindly sent me typical specimens for compa- 
rison. J have mentioned this in my paper. Moreover, 
Pourtalés, in the‘ Blake’ Report for 1878, p. 201, confirms my 
determination, and says, “In the Florida Straits ..... 
quite a number were dredged of the more elongated shape, 
which Mr. Lindstrém has tound to be the prevalent form in 
the Eastern Atlantic.”’ I then failed, and I still fail, to detect 
any pali, or any thing at all deserving that name, in them ; and 
Pourtalés also says that those of a higher order are not very 
distinguishable from columellar processes. He, moreover, 
admits that the pali may be wanting in smaller specimens, 
when he says that he found them “ quite distinct in large 
specimens in front of the tertiaries.”” It seems, then, that if 
pali exist at all they are highly variable, and occur in some 
specimens, while they are deficient in others. Nor are the 
pali at all clearly indicated in the figure given by Pourtalés 
in ‘ Deep-sea Corals,’ pl. iii. fig. 2. 
Leptocyathus? halianthus, Lindstrém.—Prof. Duncan says 
that either the description or the figure is wrong, as they con- ~ 
tradict each other. Both are correct, though I admit that the 
former might have been more complete, and that there might 
have been one figure more. The case stands as follows :— 
There are in the Swedish State Museum two specimens 
dredged up alive, during the expedition of H. Swed. M. ship 
‘Eugenie,’ off Cape Frio, both broadly attached to the valves 
of a Pecten. One of them is the original of the figure 9 of 
pl. i. in my paper, and there only the tertiary septa coalesce 
with the secondary ones. But in the other specimen those 
of the fourth and the fifth orders are united to those of the 
third in one moiety of the coral, while in the opposite 
moiety they are straight and do not coalesce at all. This, 
taken together with the former specimen, shows what a highly 
variable character this coalescence of the septa is. ‘There are 
no pali. The coste are large and prominent where they are 
)
