and these are arranged opposite each other on the bell margin. The eight 
rows pf lasso-cells on the outer surface of the bell are similar to those in 
EE. ochyacea, 
The\ youngest larva of E. ochracea from Newport has four tentacles. A 
larval “ctoplewra with two tentacles has not been recorded previous to this ob- 
servation of the Bermuda species.

The Eetopleura mentioned above was accompanied by several young Tubu- 
larians, all in a like stage of development, which could not be placed in any 
known genus. The outlines of the bell are similar to those of Sarsia. Its 
outer surface is covered with nematocysts, arranged without regularity. 
The Medusa is peculiar in possessing two simple tentacles placed opposite 
each other on the bell rim, and a pair of small, apparently rudimentary ten- 
tacles at the extremities of the two remaining chymiferous tubes. These Me- 
dusee are the larvee of some unknown Tubularian related to Sarsia. 
Oceaniopsis gen. nov. 
The genus Oceaniopsis differs from other members of the Oceanide in pos- 
sessing four octocysts, from the neighborhood of each of which, on the bell 
mar in, there arise small tentacular filaments. 
Oceaniopsis Bermudensis sp. nov. 
Figs. 8, 9, 10. 
Two stages in the development of this jelly-fish were found. The younger 
of these has two large, opposite tentacles, while the older has four. 
The characters of the former (Figs. 8, 9) are as follows. The bell is low, 
without raised apex, with smooth external surface and thin flexible walls. 
There are four spherical ovaries (s) which hang from the chymiferous tubes 
midway between the proboscis and the bell margin. Two long tentacles 
(Fig. 8) take origin opposite each other on the bell rim, The rudiments of 
two others (Fig. 9) are plainly visible on the bell rim, midway between the 
last, as prominent projections on the bell margin. The bell bears four oto- 
cysts. From the neighborhood of each otocyst on the bell margin spring three 
or more, sometimes two, small filaments. No filaments are found, as in Eu- 
cheilota, in the neighborhood of the tentacular bulbs. 
An older stage (Fig. 10) of the same Medusa has four well-developed ten- 
tacles, each of which arises from a tentacular bulb, situated at the terminus of 
the radial tube near the bell margin. There are no other additions of impor- 
tance in this larva, which is probably not far removed in shape from that of the 
adult. Several larvae of Oceania languida A. Ag., occurred with Oceaniopsis.
