5. Cirrus nebulosus (Plate [9]). Hazy cirrus.
Characterized by the absence of sharply defined lines, fibres, or streamers; all parts of the cloud being hazy, and suggestive of other varieties of cirrus out of focus. Ci. Neb.
6. Cirrus caudatus (Plate [8]). Tailed cirrus.
Characterized by small hazy or fluffy heads behind or below which hang long streamers, which taper away more or less to a point. The tails are sharply defined, and so are the edges of the heads. Ci. Ca.
7. Cirrus vittatus (Plates [12] and [13]). Ribbon cirrus.
Characterized by formation in long bands of cloud, sometimes made of parallel long fibres with cirrus haze linking them together, sometimes consisting of a long bundle of fibres, from which others diverge at an angle as shown in the plate. Ci. Vt.
8. Cirrus inconstans (Plate [10]). Change cirrus.
Characterized by a peculiar ragged, wavy appearance. It is generally only the beginning or the end of a mass of cirro-stratus or cirro-cumulus, but occasionally it vanishes shortly after its appearance, without reaching the further stage. Ci. In.
9. Cirrus communis (Plate [11]). Type cirrus or common cirrus.
