each bunch being distinctly club-shaped 
branched mouth-tentacles, each ramifi- 
cation of which ends in an oval group 
of nematocysts. Mouth-tentacles highly 
retractile and not evident when animal 
is disturbed. The bunches of marginal 
tentacles are borne on conspicuous swell- 
ings or pads at terminations of the four 
radial canals, and each tentacle has a black 
eye-spot above its base. 
Colors . — Tentacular bulbs and ovaries 
yellow. Ends of middle tentacles of each 
bunch dark brown. 
Distribution — Nantucket and Nau- 
shon (A. Agassiz), Newport, Vineyard 
Sound, Buzzards Bay.

( Hippoerene carolinensis McCr. Proc. Elliott Soc., vol. I. No. 1, p. 164.) 
Bell subglobular, thick. Marginal tentacles in four bunches, arising from marginal swellings 
which are narrower and more pointed than in the preceding species. Tentacles all alike, with slightly 
enlarged ends, and eye-spots over their bases. Proboscis slender, with four branched mouth-tentacles 
ending in nematocyst batteries. Radial canals, 4. 
Colors . — Tentacular bulbs red, edged with yellow. Proboscis red. 
Distribution . — Common in the Woods Hole region. 
Bougainvillia superciliaris Ag. Fig. 90. 
(Cont. Nat. Hist. U. S., vol. IV, j>. 289.) 
Bell subglobular, very thick. Marginal tentacles in four pairs at birth, later in four bunches. 
Tentacular bulbs and eye-spots as in the preceding species. Proboscis thick and heavy but not 
reaching much more than half way to the bell opening, ending in four branched mouth-tentacles 
terminating in nematocyst batteries. Radial canals, 4. 
Colors . — Marginal sense-bodies orange red surrounded by yellow. Proboscis pale yellow, tinged 
with red distally.

Lizzia grata A. Ag. Fig. 91. 
(Proc. Boston Soc. Nat. Hist., p. 100.)
