D. campanulata, pistillo ore quadrangulare, costis quatuor cirri-productis. 
In Baffin’s Bay and the adjacent seas, but rare ; body hyaline, campanulate, 
the margin not ciliate ; length usually under half an inch, and the diameter 
under a quarter of an inch ; peduncle tubular, flesh-coloured, capable of ex- 
tension to more than twice the length of the body, enlarged and quadrangular 
near the mouth, which distends to receive its prey ; from the base of the 
peduncle proceed four delicate blood-red costee, terminating at the margin in 
soft granular cirri, which can be extended at pleasure to more than an inch in 
length, or contracted to less than a quarter. 
This species is allied to the Dianaea digitala (Medusa Digitale, Faun. Green. 
No. 361,) and still nearer to the D. Papillata, (Medusa Papillata, Zool. Dan. 4. 
24. tab. 140.) but the margin is without the ciliae of the former, or the globes 
of the latter. It falls under the Genus Geryonia of P6ron, Ann. du Museum 
Cyanea Arctica.
