Of these, grammarians reckon four kinds: the first consisting of an iambus and spondee, as fālūtāntēs; the second, of a trocheus and spondee, as cōncitāti; the third of a spondee, and an iambus, as cōmmūnicāns; and the fourth, of a spondee and trocheus, as īncāntārē. See the articles Spondeus, Trocheus, &c.
