150 BULLETIN OF THE 
The mouth rarely reaches outside the entrance into the bell cavity. The 
peduncle in the figure has a cellular appearance. This resemblance to cells 
may be due simply to superficial folding of its walls, and the peduncle itself 
may be transparent and. gelatinous, like the remainder of the bell from which 
it hangs. 
The sexual organs are formed of four globular bodies, of orange brown color 
in which darker colored patches are distinguishable. The specimen figured is 
a female. The male is unknown. The oral tentacles are simple, short, four in 
number, and clothed at their tips with many knobs. 
The tentacles are numerous, uniform in size, flexible, hollow, carried like 
those of Trachynema or Turritopsis closely coiled about their bases. Their 
color is greenish, with deeper coloration in the bulbs. Tip of the tentacle 
pink. Number of tentacles, thirty-two. 
A bright crimson pigment spot is borne on the under side of the enlarged 
base of the tentacle, a short distance from its union with the rim of the bell. 
This position of the pigment spot is very characteristic. 
Development from the egg unknown. Male unknown.

This jelly-fish I have never seen, and the description is made from a sketch, 
with notes loaned me for that purpose, by Mr. Agassiz. 
Gemmaria gemmosa, McCrapy. 
Plate I. Figs. 10, 11, 12. 
McCrady first described a new jelly-fish from Charleston Harbor allied to 
Zanclea of Gegenbaur, to which he gave the name of Z. gemmosa, suggesting at 
the same time that its characteristics may be important enough to place it in a 
new genus for which he presents the name Gemmaria. Mr, Agassiz adopts the 
name Gemmaria gemmosa, and gives additional drawings of what seems to have 
been the same jelly-fish. The form which is here described as the adult of 
G. gemmosa was discovered by Mr. Agassiz, from whose drawings and notes 
this description is made. 
The bell is teacup-shaped, with an apical hemispherical protuberance, which 
rises slightly above the apex. The bell walls are thin. Surface, except in four 
meridional lines yet to be mentioned, smooth, The radial tubes simple, narrow, 
smooth in profile, and four in number. Proboscis without peduncle, and ex- 
tending normally to the opening into the bell cavity, and sometimes capable of 
great protrusion outside the bell. Oral tentacles wanting. The mouth open- 
ing is circular. The lips are studded sparsely with large lasso-cells. The 
lower part of the proboscis is slender, the upper very much swollen with the 
ovarian glands. Ovaries in four spherical lobes, through the walls of which 
eggs with germinative dot and vesicle can be plainly seen. 
The tentacles are primary, uniform in size and length, and four in number. 
The tentacular bulbs are large, and each tentacle is thickly crowded with
