This genus is recognized by the eight tuberculated projections on the 
exumbral margin of the bell. From these projections there extend to 
the vicinity of the center of the bell eight ribs or radial depressions, 
which appear on the subumbral surface as radial depressions between 
which the octants of the subumbrella are somewhat swollen. Near 
the center of the subumbrella is a ring of eight knobs which lie one . . 
in each octant between the above-mentioned depressions. 
There is a well marked vellum below the marginal projections. The 
radial projections appear as elevations on the exumbral side of the bell 
in alcoholic specimens. 
In my former paper* I referred this genus to the Narcomeduse of 
Heckel. There is no reason from a study of new material to change 
that opinion of the affinities of the family of Halicreasidze. 
Family PEGANTHID, Heckel. 
Among the families of Narcomeduse described by Heckel is the 
Peganthide, a family without radial canals and gastric pouches in the 
subumbrella but with a festoon canal. The sexual bodies are either 
lobed or form a non-continuous band on the under floor of the stomach. 
Among the medusie collected by the Albatross is one which has a 
close likeness to the genus Pegantha of the Peganthide but which 
differs from the known species of this genus so widely that it may be 
necessary later to call it a new species. 
This Pegantha somewhat resembles P. quadriloba, although the genital 
sacs are not as markedly four-lobed as Heckel’s description of this 
species would seem to indicate. It has marked lobes in the sexual 
glands, but the poor condition of preservation and the rupture in one: 
or two instances of the gland from its attachment rendered it impos- 
sible for me to tell to what species this Pegantha belongs. 

* Bull. Mus. Comp. Zool., ix, 8, p. 306. In one of the two specimens of Halicreas 
there described, sausage-shaped sexual bodies were observed hanging from the under- 
side of the bell, In one of the above specimens (15750) glandular bodies were ob- 
served in the subumbral radial furrows.
