The radial tubes are unbranched, broad, with jagged profile, and four in 
number, The proboscis is shorter than that of Stomatoca, and extends two 
thirds the distance down the bell cavity. There is no peduncle. The ovaries 
are large, and. crescentic shaped, filling a large part of the upper portion of the 
bell cavity. They are of a cream color, with a greenish tinge. Oral tentacles 
not folded, and undivided, without knobs, and four in number. At times the 
oral tentacles by a contraction of the bell walls are extended beyond the bell 
opening, as is also the case in S. apicata. Veil thick, muscular, and when at 
rest re-entering the bell cavity. It plays a great part in the motion of the 
animal. Tentacles two, very long and flexible, and at times coiled into a shape- 
less snarl around the tentacular bulb. Their color is light green, with extremi- 
ties white. "lentacular bulbs large, pale green, and cream-colored, in the motion 
of the medusa carried sidewise like those of Stomatoca. Their color, as that of 
the whole tentacle, is often tinged with pink. Between the two long tentacles 
in either semicircle of the bell margin there are three slight projections, each one 
of which has a bright pigment spot of crimson color. The pigment spots are 
not borne on small tentacles, as in Stomatoca, but on simple protuberances, 
Otocysts wanting. 
Development unknown. Eggs small, white, cast in great numbers in the 
glass dish in which the jelly-fish is confined. 
Locality, tide eddies in Laboratory Cove, Newport, R. I. Many specimens 
were taken each summer.

This beautiful jelly-fish was first described by McCrady, under the name of 
Saphenia apicata. It differs very greatly from £, dinema of Eschscholtz and 
Forbes in the shape of the bell, as compared with the figure given by the lat- 
ter. Eschscholtz gives no figure of S. dinema, and, until a comparison of speci- 
mens can be made, it is best to retain the specific name of apicata for our 
representative of the genus. 
The only published figure of S. apicata is a poor one by McCrady. A simi- 
lar jelly-fish was mentioned by Mr. Agassiz, from New England waters, but he 
has given no figures of it, and added nothing to McCrady's account. 
The bell has an irregular, triangular profile, and the upper angle is formed 
by a conical projection, apically placed, the height of which is oftentimes 
double that of the bell itself. This prolongation varies in size in different 
specimens, now very slender, and then short and blunt. It may also be at 
times, as McCrady says, jauntily carried on one side. The substance of the 
apical projection is solid throughout. The bell walls are thin and with smooth 
surface, The diameter of the bell is slightly larger near the margin than a 
little above. The chymiferous tubes are broad, with jagged outline, and are 
four in number, Near their junction with the two tentacles they enlarge into
