Beroe Globuleux. Encyd. Meth. PI. xc. f. 3, 4. 
In Davis’ Strait and Baffin’s Bay ; frequently rising to the surface amongst 
ice, having eight ciliate ribs most beautifully resplendent with green and red. 
DiANiEA GlACIALIS. 
Plate 1, fig. 1. 
D. campanulata, pistillo ore quadrangulare, costis quatuor cirri-productis. 
In Baffin’s Bay and the adjacent seas, but rare ; body hyaline, cam- 
panulate, 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 extension 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 costae, 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. Grosn. 
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 Peron, Ann. du Museum.

month of May, several individuals rose immediately to the surface, which were
