those of Maas may readily be accounted for by the circumstance that his figures 
were drawn from preserved specimens that were probably distorted by con- 
traction, A very closely allied species is found at the Dry Tortugas Islands, 
Florida, 
Liriope hyalina, nov. sp. 
Plate 9, Fig. 32. 
Generic Characters. Liriope, Lesson, 1848. Geryonide with 4 gonads upon 
the 4 radial canals. The circular canal is simple, and without blind, centripe- 
tal branches. There are 8 permanent tentacles; 4 of these are long, hollow, 
and radially situated, and 4 are short, solid, and interradial. Eight otocysts ; 
4 radial, and 4 interradial, 
Specifie Characters. The bell is about 14 times as broad as high, and the sides 
are straight and sloping. It is 6.5 mm. in diameter. ‘There are 8 tentacles; 
4 of these are radial, and are about as long as the diameter of the bell. They 
are hollow, and are covered with rings of nematocysts. The other 4 tentacles 
are interradial and very short, and are carried curled sharply upward. 
There are 8 otocysts (4 radial and 4 interradial), each containing a single 
spherical otolith. The velum is prominent. The radial canals are wide in the 
neighborhood of the circular vessel, where the gonads are found. In the upper 
portions of their length, however, near the proboscis, they are straight and 
slender. The proboscis projects for a considerable distance beyond the velar 
opening. The mouth opening is surrounded with nematoeysts. This Medusa 
is extremely hyaline, excepting that the entoderm near the mouth of the pro- 
boscis is slightly rose colored. 
This form was found off Tavinni Island and in Suva Harbor. It is closely 
allied to Liriope seutigera, MeCrady, of Charleston Harbor and the West 
Indies,

This Medusa was found by us in the Fiji Islands. Haeckel describes it from 
the Canary Islands, and we have found it at the Dry Tortugas, Florida. Ina 
‚paper that will soon be published in this Bulletin, we hope to present a figure

Several specimens of a Cunina that is closely allied if not identical with 
Cunina octonaria of Charleston Harbor, South Carolina, were found by us in 
the Fiji Islands early in January, 1898. The Fijian form may be slightly less
