is sharply distinguished from it, especially through the characters 
of its pores and tentacle scales. 
The new genus, Ophiotjalfa (after the name of the vessel, 
Tjalfe”), may be shortly thus characterized: Disk covered with 
comparatively small, thick plates, with no conspicuous primary plates. 
No arm comb. Dorsal and ventral plates continuing to end of arm. 
Inner tentacle pores close to mouth-edge; tentacle scales small, 
papilliform. Armspines small, appressed. 
As Ophiozona tjalfiana this species is evidently no arctic 
Species, but belongs to the fauna of the warm region of the North 
Atlantic.
