ὀσμύλη - Eledone moschata (LSJ Entry)

ὀσμύλη, ἡ, A.a strong-smelling musky octopus, > Eledone cirrosa> , Arist.Fr.305:

According to what I can find, the species of octopus with a musky smell is Eledone moschata, not Eledone cirrosa.

It seems likely. See A. W. Mair’s note in the 1928 Loeb edition of Oppian:

LSK gives θαλάσσιος πολύπους ἔχων ἰσχυρὰν ὀσμήν…πρβλ. ὄζαινα, βολβίδιον.
