What is marvellian stanza?

He often wrote 8 line stanzas (octets) with iambic tetrameter meter and composed of 4 rhyming couplets (aabbccdd) (see The Unfortunate Lover, The Gallery, Damon the Mower, Upon Appleton House, Upon the Hill and Grove at Bilbrough). But he doesn't have a particular stanza named after him as far as I know.
