variations. In some the stem is nearly 
smooth from the base to the cup, where 
there are only a few slight twists ; in 
others there are several distinct though 
irregular rings or twists at the base, a 
few about the middle of the stem, and 
others at the base of the calycle; in 
almost all there is one very distinct ring 
at the base of the latter, as Mr. Alder 
shows in his figure *. There is also 
a peculiar hollow at the base of the 
calycle; but this cannot be called a 
ring. Campanulciria Hincksii.

Common in deep water. Many specimens were also found 
in the stomach of Echinus esculentus from the laminarian zone.

Not uncommon on the under surfaces of stones near low- 
water mark. The peculiar zigzag form of the stem, with the 
arms of the forks tending in opposite directions, together witli 
the short, broad, and smooth-edged hydrothecae, are character¬ 
istic. The long pedicels of the hydrothecae had their central 
smooth portions peculiarly flattened out, so as almost to 
assume a fusiform aspect.

Occasionally found on Antennularia antennina and other 
zoophytes from the coralline ground. The form agrees in most 
respects with the published description. The calycle is very 
narrow and deep, with six to eight large teeth on the margin ; 
stalk rather slender (much more so than in Clytia Johnstoni ), 
with several distinct rings below the cup, and many less distinct 
towards the base. The peculiar slenderness of the stalk, the
