bell-height. There are 4 slightly recurved lips with sinuously folded margins. The gonads 

 are complexly folded, swollen, projecting masses on proximal parts of the 4 radial-canals, upon 

 the peduncle adjacent to the stomach. The bell is colorless, gonads pale yellow, 

 orange to brown. Found at Nagasaki, Inland Sea, Japan.

GENERIC CHARACTERS. 



Thaumantiadie with 4 main radial-canals, each giving rise to 2 simple, unbranched 

 side branches which, together with the main radial-canals, connect with ring-canal at margin. 

 Gonads upon the 4 main canals and side branches. Marginal clubs and cirri may or may not 

 be present. 12 or more tentacles. 



This genus is closely related to St/uuoJmus, but is distinguished by the fact that the side 

 branches of the radial-canals join the marginal ring-canal, whereas in StauroJiscus they end 

 blindly. 



Maas, 1904, would regard StiiiirnJi.^-ns as a young stage of Haeckel 's ('.unnntn. but nix- 

 studies of numerous specimens of Xtiiii>-rnlis?ns at Tortugas, Florida, convince me that the 

 medusae become mature with blindly ending side branches upon the 4 main radial-canals.

Bell thin and flexible, 14 mm. in diameter. 12 short tentacles with well-developed basal 

 bulbs. The 4 tentacles at the bases of the 4 main canals are about twice as long as the 8 which 

 arise from the ends of the lateral branches. The longest tentacles are, however, only about one- 

 sixth as long as bell-diameter. Between each successive pair of tentacles there are J small 

 protuberances upon the bell-margin, each one of which bears a sensory-club. Velum narrow. 

 Each of the 4 radial-canals gives rise to a pair of opposed lateral branches and thus 12 

 canals reach the circular vessel 30 apart. The gonads are developed upon these 12 trident- 

 like terminal canals. Manubnum is \et\ short, mouth-opening wide. Gelatinous substance 

 and entodermal lamella of bell of a brownish tinge. Genital organs, basal bulbs of tentacles, 

 and manubrium are light-sepia in color. Bulbs of sensory-clubs are dark-brown. 



This medusa was found near Suva Harbor, Fiji Islands, South Pacific, in December, 1897. 

 Haeckel describes a small specimen 4 mm. wide from New Guinea. (See fig. 1 13.)

As is apparent from the above, the name C.ir, i,-im was first used in botany in 1802, and in 

 zoology for a medusa in 1807. Its previous use in botany does not inuiK-u- \\ith its use in 

 zoology. The type species is Cuvicria carisockroma of Peron from the tropical Atlantic.
