162 BULLETIN OF THE 
like structure” extended from the rim of the bell inwards at right angles to 
the vertical axis, The mouth is a simple circular opening in the centre of the 
washer last mentioned. The upper walls of the stomach are formed by the 
concavity in the lower surface of the umbrella. The stomach cavity appears 
full of granular particles, which are probably globules of chymiferous fluid. 
Sexual organs had not begun to develop. Development of egg unknown. The 
jelly-fish studied is probably an immature one, as the size and absence of 
sexual glands indicates. Whether it is identical with the Mediterranean species, 
which reaches a much larger size, is yet to be made out. It is not a frequent 
visitor in Narragansett Bay, and is undoubtedly brought there by the warmer 
waters of the Gulf Stream. Its anatomy shows that it is very different from 
Prof. McCrady’s Cunina octonaria. 
This description was made up from figures by Mr. Agassiz and a few rough 
sketches made by the author. 
Liriope scutigera, McCrapy.* 
Plate VI. Figs. 7, 10, 11. 
A single specimen of L. scutigera, McCr. was found at Newport in the sum- 
mer of 1878. 
Its bell is hemispherical, very transparent, with thick walls and smooth ex- 
ternal surface. Radial tubes thread-like, unbranched, and four in number. 
Proboscis elongated, slender, with a long peduncle, which extends very far out- 
side the bell opening. This peduncleis highly flexible. The lips of themouth 
are simple, not elongated into oral tentacles, and cruciform when seen from be- 
low (Plate VI. fig. 10). Upon the lips are placed many lasso cells, The color 
of the lips is purple. A short gastrostyle hangs down as a continuation of the 
peduncle inside the stomach. No commensalists attached to it. 
The tentacles are long, hollow, very flexible, and four in number. Lasso- 
cells are arranged. in rings, alternating with smooth surfaces along each tentacle 
to its very tip. 
Otocysts four, each one containing a single endodermic otolith. Each otocyst 
is sessile on the margin of the bell, and is accompanied by a club-shaped 
structure mounted on a short peduncle (Plate VI. fig. 11). The ovaries are 
situated on the radial tubes. They are heart-shaped, and so inflated with ova 
that their edges closely approach, where their width is the greatest. 
The development of the egg is unknown. 
* McCrady has published a partial description of this jelly-fish. in his “Gymnoph- 
thalmata of Charleston Harbor," p. 106. A figure of the same is given in the North 
American Acalephæ, p. 60. The author of the latter does not represent the heart- 
shaped ovaries, but in his deseription says of them that they are more heart-shaped 
than McCrady describes. L. scutigera, MeCrady, and L. Catherinensis, Fritz Müller, 
may be the same medusa,
