RING an excursion to the coast of Maine and Bay of 
Furidy last season, many interesting and rare marine animals 
were observed and collected by “myself and companions.* 
mong the most remarkable new species is a vey large and 
beautiful Discophorous jelly-fish, which is the type of a new 
genus ge scent a family previously unknown upon our 
Atlantic 
In size ‘had general appearance it has some resemblance t0 
Cyanea arctica, for which it may, possibly, have been hitherto 
mistaken by casual observers, for it seems scarcely probable 
that such a large and conspicuous species, which occurred twice 
_ among the wharves at Eastport, could otherwise have so long 
escaped observation. Its color, however, is much lighter than 
that of Cyanea, and yellowish rather than brown or reddish, 
while the much less numerous tentacles are larger, flattened, 
with one edge crenulated and bordered with white, while its 
entire structure is quite different.
