An Ephyra, which was at first regarded as the young of Linerges, on closer 
examination was found to have sixteen instead of eight otocysts, and the same 
number of tentacles. In many other respects, however, it closely resembles the 
young Linerges. The bell is flat, disk-shaped, with a slightly raised and rounded 
apex. The marginal lappets, which are thirty-two in number, are long and 
flat, thin and pointed at their free extremities. When they are extended, the 
central region of the bell, as seen from one side, appears as a slight protuber- 
ance above the plane in which they lie. When the marginal lappets of the 
bell are contracted, they fold under the oral side of the bell so that their tips 
meet at a point in the centre below the mouth. The incisions which separate 
the marginal lappets of the bell extend to two depths; one set of incisions 
corresponding to the position of the tentacles, and the other to that of the sense 
bodies. The former are the deepest, and the bell margin is cleft by them in 
such a way that the rim of the bell is divided into sixteen pairs of marginal 
lappets. The color of the bell is a brownish yellow, in which are darker spots 
and patches of black pigment. The mouth is simple, like that of the young 
Linerges, and from its lips hangs a single row of small papille, which are want- 
ing in the Ephyra of L. Mercurius, Haeck. The adult of the Ephyra will 
certainly be found to be a very unusual Discophore. Three genera which it 
approximates in the number of marginal sense-bodies are Cassiopea, Collaspis, 
and Atolla. From both of the last two, however, it differs so widely in the form 
of the bell and other particulars that it cannot be referred to either of them. 
Cassiopea, which has sixteen otocysts, has no tentacles in the youngest larve 
studied.* The Ephyra of Linerges is easily distinguished from that described 
* The only genus to which I have been able to refer this Ephyra is Cassiopea. 
Cassiopea (Polyclonia) frondosa is one of the most common Medusz on the shoals 
along the Florida Reefs, and probably is also found in the Bermudas, although I
