[Cnidaria] Rhabdoon???

[Sofia Pyataeva]

Dear Cnidariologists,
Could you help us to identify this medusa?
It was found not far from Iceland and preserved in formalin.
Umbrella looks oblique, but probably owing to unfortunate fixation. It looks like there are no bulbs! Four radial canals and circular one, single tentacle, the tentacle ending consists of numerous stalked groups of cnidocysts.
It seems to be Rhabdoon singulare, but we found no cnidocysts tracks... (Or possibly these light-refracting points in exumbrella are cnidocysts? (showed by arrows)). But they are scattered in exumbrella and do not form tracks...
Please see attached pictures!

Thank you very much in advance,
Kind wishes,
Sonya.
