This form, discovered by me in 1849, has hitherto been found 

 only in Vestfjorden, near the Lofoden Isles, half a mile eastward 

 of Reine (67° 57' N. lat.), at a depth of 40-50 fathoms, on a 

 muddy sandy bottom ; here it is very abundant, and is often 

 drawn up with its long tentacles entangled in the meshes of the 

 dredge.

 Amalthaa uvifera, O. Schmidt, Handatlas der vergl. Anat. tab. 9. fig. 2. 



Near the island of Loppen, in Fin mark, at a depth of one 

 fathom, with a sandy bottom. This form is distinguished from 

 the two preceding species by its smaller size (1 inch or but little 

 more), shorter inferior and fewer superior tentacles. As regards 

 its Medusa-buds, it appears to come nearest to C. Sarsii, as, 

 according to Schmidt's figure, it has four marginal bulbs of 

 equal size, which, however, are here far larger than in the former 

 species. 



4. Corymorpha ? annulicornis, Sars, n. sp. 



Proles hydriformis §-pollicaris, tentaculis inferioribus filiformibus 

 longioribus annulosis 20, superioribus 8-10 uniserialibus brevissimis 

 apice globoso ; pedunculis gemmigeris brevissimis, gemmis medusinis 

 majoribus et paucioribus obsitis. 



Proles medusiformis decidua, pallio breviter campanulato, canales 

 quatuor radiantes exhibente, antice aperto, margine bulbo seu cirro 

 marginali unico magno, conico-elongato vel cylindrico, introrsum 

 flexo, cseterisque tribus indistinctis, ornato. 



This small and very distinct form, which, however, I do not 

 place in the genus Corymorpha without some doubt, has only 

 occurred to me once near Floroe, in the diocese of Bergen, where 

 I met with two specimens, at a depth of 30-40 fathoms, on a 

 muddy bottom. It differs rather widely from the other species
