The plumages, morphological characteristics and occurrence of the populations of Cisticola juncidis in Australia are reviewed. Three subspecies are recognized and redescribed; one, laveryi, is described as new, differing from norrnani in its heavier dorsal streaking in eclipse plumage and from other subspecies in the presence of well-marked cinnamon mirrors in the tails of females in nuptial plumage. Morphological differences between C. juncidis and C. exilis in Australia are summarized; shape of wing is critical in separating the two species in eclipse plumage.
