The radial tubes are imbranched, 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 undi\aded, 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, wath extremi- 

 ties white. Tentacular 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 dififers very greatly from S. 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 difterent 

 specimens, now very slender, and then short and blunt. It may also be at 

 times, as McCradj' says, jauntily carried on one side. The substance of the 

 apical projection is solid throughout. The Ijell walls are thin and with smooth 

 surface. The diameter of the bell is slightly larg(;r near the margin than a 

 little above. The chymiferous tubes are broad, with jagged outline, and are 

 four in nuinl)er. Nwir their jiiiictioii with tlie two tentacles they enlarge into
