are nearl}' hemispherical, their rounded surfaces projecting in the 

 cavity of the disk. They are situate about one-fourth the length 

 of a radiate tube from the bell-margin. The tentacula, sixteen 

 in number, have very long and slender lashes, with bulbs of mod- 

 erate size. The marginal capsules usually contain a single cor- 

 puscle each, and are quite small and not very conspicuously 

 placed. 



I have spoken of the cavity of the bell as deep in this species, 

 but this is not the result of a campanulate form, such as is seen in 

 Campanularia noliformis, but of the thinness of the bell-wall. In 

 a slightly contracted condition my single specimen presented a 

 rather unusually flaccid appearance, due to the thinness and hem- 

 ispherical form of the disk, but, in full activity, its distended disk 

 and long graceful tentacula made it a very beautiful object. 



The only specimen found was taken on the 22d of May, 



PHORTTS, nov. gen. 



The general outline of the disk is probably hemispherical, but 

 unlike the preceding genera the bell cavity is exceedingly shallow, 

 and consequently the solid part of the disk of excessive thickness, 

 giving a heavy-laden and clumsy appearance to the animal at first 

 sight. The digestive trunk is not cylindrical, but narrows into a sort 

 of neck above before reaching the radiate tubes, along whose course 

 it sends out processes of sufficient length to give, when viewed 

 from above, the appearance of a four-rayed star. The four radiate 

 tubes are not regular in their curvature downwards, but first 

 ascend slightly above the base of the digestive trunk. Nearly at 

 the point where they begin to descend, begin the sexual organs, 

 four elongate but not exactly cylindrical organs, which descend 

 towards but do not reach the marginal canal. Their structure is 

 peculiar. Within the sexual gland and on the sides of the radiate 

 canal, are placed small reddish glandular bodies, in pairs, one on 

 each side of the tube. There are in each sexual organ from three 

 to four pairs of these glands. The margin is provided with from 

 twelve to fourteen tentacula resembling those of Epenthesis, and 

 wanting the small lateral tentacula of Eucheilota and Eutima. 

 In the interior of each bulb however there is a pair of small red- 

 dish glands like those described in the sexual organ. Between 

 every two tentacula there are one or two knobs provided with 

 thread-cells and from three to four small marginal capsules, each 

 bearing one or two corpuscles.
