159 stream SE from here. Down to that altitude the main ridges are still mossy and Sama (common at 1800 m.) the dominant tree. Oaks (2 spp.) and Castanopsis are plentiful on the slopes and smaller ridges, but not domin- ant and the character of the forest differs little from that of the rain- forested ravines at 1800 m. Many plants of lower altitudes of course ap- pear, and I had a good day. A very interesting find was Orania distinha hitherto only known from Kubuna in the east, where it was discovered by me in 1933. The chief attraction for Toxopeus at the 1500 m. camp is a series of three waterfalls in the stream, where the open sunny conditions are attractive to butterflies and dragon flies. The ravine is, however, so deep that the sun does not reach his camp until eight o'clock, and on the stream, some little distance below, there is probably no sun until an hour or so later. Gold mines plane flew over the Kerom and returned to Hollandia. Crew quartered with Archbold. A transport up from Idenburg. Thursday, January 26, 1939. Another good day: chilly dawn, more or less overcast, with wind from SE: more or less sunny to 1 PM, when the wind changed and clouds which glotted out the Idenburg all morning, rose over the ridge and the usual mist and light rain followed to 6 PM: evening fairly clear but heavy lightning to N and NE. Spent the day in camp, preparing specimens and labelling dry material. Toxopeus returned from 2100 m. camp, and with his assistant and six Dyak collectors, went down to his 1500 m. camp. Gold mine's plane flew to Tana-merah from Hollandia intending to return, but cloudy conditions S. of the range prevented it doing so.
