[13] MEDUS& FROM THE GULF STREAM. 525 
The collar lobes of these specimens are girt by a horseshoe-shaped 
festoon canal, as in the Peganthide, but the bell is more flexible and 
not crossed by the radial elevations and depressions upon the exum- 
brella. * 
Umbrella flat, discoid, with a ring of sexual bodies divided into as 
many lobes as tentacles and alternating with them. In each marginal 
lobe there is a genital sac, which is free from the wall of the lobes on 
the floor of the gastral pouches. 
Tentacles numerous, 20 to 22 or more in number, springing from the 
sides of the body or the peripheral border of the umbrella. Tentacles 
longer than the diameter of the bell. The marginal collar is composed 
of as many lobes as there are tentacles, and each has a festoon canal. 
Peronie wanting. ? 
The following notes were made from a specimen with 22 tentacles: 
Umbrella fiat, lens-shaped or discoidal. Color, transparent, white in 
alcohol, flabby, gelatinous. Outer surface (exumbrella) smooth. The 
body divided into a central region and a peripheral collar. 
Central region plano-convex or double convex. The greater convex- 
ity is below. Diameter in alcohol, 20™™. 
Upper surface flat. No coronal fossa or annular indentation at the 
rim near the origin of the tentacles. 
The marginal collar is composed of twenty-two marginal lappets 
joined laterally by a thin membrane. The festoon canal broad, extend- 
ing from tentacle to tentacle in well-marked horseshoe shaped-loops. No 
sense bodies were seen, on account of the poor preservation of the 
specimen. 
The festoon canal seems to open on each side of the tentacle into the 
central stomach cavity. The edge of the marginal lappets is girt by a 
thin velum. The tentacles are long (longer than the diameter of the 
bell) and are inserted into the gelatinous substance of the bell by a 
conical root extending radially. No peronia and no marked marginal 
canal besides the festoon canal. Twenty-two gastral pouches. The 
stomach is a dish-shaped cavity bounded above by the under surface 
of the central region of the disk and below by the wallof the stomach. 
Well-marked gastral pouches. The mouth has a broad opening with- 
out protruding lips. 
The sexual bodies lie in a ring on the peripheral region of the lower 
stomach walls in the gastral pouches. In the specimen with twenty- 
two tentacles these organs were not seen. 
In other and larger specimens in which, however, in one instance at 
least, there are not as many tentacies, the sexual bodies take the form 
of sacs hanging in the lower wall of the stomach between the radii of 
the tentacles. In one case these glands are very much inflated ; in an- 
other they have the form of a paesinae: band. Of me species of Cunina 


* The species of Sint Gcieataes may ev seal turn out to be one of the 
Atlantic species of Solmaris. It may be the young of S. coronantha, Heckel,
