Philautus vermiculatus

Philautus aermiculatus, BM 1974.4805, temperature unknown, recorded at 1280 m., Gunung Lawit, Malaya. An apparently complete call series includes 14 calls in 4.75 sec. Intervals between calls are 0.15-0.21 sec. The call consists of an indistinctly pulsed section (duration 0.03 sec.), a series of seven pulses (duration 0.04-0.05 sec.), and an unpulsed section (duration 0.01-0.015 sec.). Amplitude modulation is distinct. Fre- quency modulation is weak or absent: the dominant (fundamental) frequency is 1.8-2.6 khz., and there are harmonics at least at 3.6-4.2 and 5.4-5.8 khz. [1]
