58. In Fig. 59 is seen a portion of the Jelly-fish disk, with the 

 fringe of tentacles highly magnified. The disk of the Eucope 

 (Fig. 60) looks like a shallow bell, of which the proboscis often 

 seems to form the handle ; for the disk has such an extraordi-

nary thinness that it turns inside out with the greatest ease, so 

 that the inner surface may become at any moment the outer one, 

 with the proboscis projecting from it, as in Fig. 60, while the next 

 movement of the animal may reverse its whole position, and the 

 proboscis then hangs down from the inside, as in other Jelly- 

 fishes. (See Fig. 61.) 



The tentacles are solid and stiff like little hairs, and two of 

 them, in each quarter-segment of the disk, have small concretions

 Along the chymiferous tubes little swellings are developed, which 

 increase gradually, and become either ovaries or spermaries, 

 according to the sex of the animal. (Fig. 63.) In the adult the 

 genital organs hang down, like elongated bags, from the chy-
