174 DISCOPHOR^. Part III. 



which belongs to the Campanularians, is numbered among the 

 CharybdeidiB proper, and many most heterogeneous genera 

 are associated with the Marsupialidte. 



The species added to this genus by later observers do not 

 belong to the same genus, and not even to the same family. 

 They are Thalassantheae and Brandtidae. Charybdea bitentacu- 

 lata Q. and G., is a Campanella ; Ch. bicolor Q. and G., consti- 

 tutes a distinct genus, Quoya A(/. ; Ch. campanella Less., may 

 also constitute a distinct genus.

 Tamoya Fr. Midi, Abhandl. Naturf. Halle, 1859. I have restricted 

 the genus Tamoya Midi, to the species with simple tentacular 

 lobes, and referred the other to Chiropsalmus.

T. alata Ag. — Carybdea alata Eeyn. in Less., Cent. Zool., PI. 33, 

 fig. 1. — Atlantic Ocean (Reynaud). — It remains doubtful to 

 what genus Lesson's Marsupialis flagellata, from New Guinea, 

 ought to be referred. It constitutes, probably, a distinct 

 genus, on account of its tentacles. 

 Bursarius Less., 1836. Closely allied to Tamoya, as restricted above; 

 but differs by the marginal folds of the disk. 



B. Cytherese Less., Zool. Coq., PI. 15, fig. 1. — Beroe Gargantua 

 Less., Zool. Coq., PL 15, fig. 1, seems to be only a large, 

 decayed specimen of the same species. — New Guinea (Lesson). 

 Chiropsalmus Ag. This genus differs from Tamoya by the palmate 

 form of the lobes from which hang the tentacles. This 

 structure is very similar to that of Lucernaria, and were the 

 tentacles club-shaped, as in the latter genus, instead of being 

 long and slender, the resemblance would be striking.
