P. ignicolor ([Pl. 11E]).—The complete call consists of a short series of notes alternating with a long series. In one complete recording the numbers of notes in these series were 4-13-3-11. The notes in the short series have an average dominant frequency of 2100 cycles per second, whereas the notes in the long series have an average dominant frequency of 3150 cycles per second. The four series of notes were given in one minute and 15 seconds.
SYSTEMATIC ACCOUNTS
The museum catalogue numbers of the specimens examined, together with the localities from which they came, are listed at the end of the account of each subspecies or monotypic species. The localities that are represented by symbols on the distribution map ([Fig. 7]) are in roman type; those that are not represented on the map, because overlapping of symbols would have occurred, are in italic type.
