Mr. A. E. Verrlll on a new Jellyfish. 161 



that such a large and conspicuous species, which occurred twice 

 among the wharves at Eastport, could otherwise have so long 

 escaped observation. Its colour, 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 ; and its 

 entire structure is quite different. 



It is far more nearly allied to Hexadecomma amhiguurriy 

 Brandt, of the North Pacific ; but the latter is represented with 

 round tentacles, different marginal lobes and ovaries, and 

 broader and much more complicated mouth-folds. 



Callinema, Verrill, gen. nov.* 



Disk broad, moderately thick, with numerous broad channels 

 running to the marginal one, arranged in sixteen systems, 

 two or three parallel and undivided tubes alternating with a 

 group of five or six branching ones, which unite together into 

 one toward the central portion of the disk, each of which cor- 

 responds in position with one of the sixteen eye-bearing mar- 

 ginal lobes. Toward the marginal channel the branching tubes 

 anastomose freely, the undivided ones but slightly or not at 

 all, though two often unite into one near the margin. Margin 

 deeply and regularly divided into scolloped lobes, sixteen of 

 which bear eyes and are bilobed for more than half their 

 length, bearing the eye at the division, just below which the 

 channel in the lobe divides into two divergent branches, one of 

 which goes to each division. Alternating with the eye-lobes 

 are somewhat longer lobes, which are divided at the edge into 

 two, three, or four rounded scollops, each of which receives a 

 simple channel. Tentacles in a nearly regular circle, but 

 arranged in groups of five or six at the bases of the interocular 

 lobes, very long, highly contractile, flat; one edge double, 

 finely scolloped, the scollops again finely crenulate. Ovaries 

 large much convoluted pendent pouches. Lobes of the acti- 

 nostome four, large, elongated, pointed, complexly lobed and 

 frilled. 



Callinema ornata^ Verrill, sp. nov. 



Disk large, up to 18 inches in diameter, with conspicuous 

 radiating tubes '1 to '3 inch broad. Actinal appendages, 

 when extended, about as long as the diameter of the disk, 

 broad, much convoluted, and deeply frilled at base, the edges 

 with fine papilliform divisions. Ovaries large, hanging loosely 

 from the underside of the disk, and nearly equal in length to 

 the radius of the disk. Tentacles '2 inch broad, extending to
