ZOOLOGICAL NOTES ON COLLECTING IN BORNEO. 415 



and attracted by the smell of new felled jungle and rotting 

 vegetation. 



Across this clearing, as I write, a pretty green bird flies, 

 probably the Green Broadbill (Calyptomena viridis), which has 

 already been brought in by a Dayak collector. An hour ago 

 two Great Hornbills flew across, high above the tree-tops, 

 uttering their harsh cries. They belonged to the curious solid 

 casqued species, Rhinoplax vigil, peculiar to Borneo and Sumatra. 

 The Sea-Dayaks call them "tajak" (onomatopcetic) ; they and 

 other Sarawak tribes value them highly for their casque, from 

 which they make earrings, and for their long tail feathers which 

 they use to adorn their war-caps. 



Then, to go to the other extreme, one of those exquisite 

 gems of colour, the little Bed Sun-bird (Mthopyga temmincki or 

 siparaja) darts into the sunlight for a moment and disappears 

 again into the forest depths. 



Now a big lazy Papilio, the dark grey P. memnon (a male), 

 flaunts across ; the pretty green spotted Papilio agamemnon 

 bustles up to the entrance of the hut for a brief inspection of 

 the kitchen refuse. The yellow Terias hecabe (or it may belong 

 to one of those other forms to which lepidopterists devote so 

 many argumentative pages) has already spent an hour or two 

 after these choice remains, accompanied by the rarer Catophaga 

 plana. Lower down I see the slow flying Danaid, Ideopsis daos, 

 the easiest prey to any bird foolish enough to taste so unpleasant 

 a morsel. Yesterday two of the giant Danaids, Hestia lynceus, 

 floated down from the tree-tops. The male, when caught and 

 held between the fingers, extruded its anal brushes, but I could 

 detect no smell. He flapped lazily away, apparently unmoved 

 by his brief detention in my hand. 



The clearing as a whole is singularly poor for butterflies, 

 possibly too shut in by the steep hillsides. The commonest 

 butterfly is the brown Nymphaline, Cupha eryinanthis, of which 

 I noticed four circling round together this morning. They look 

 a bit worn, and have evidently been out some time. The red- 

 brown Cethosia hypsea turned up one morning, rather out of 

 place up here, as they usually like lower ground and nearer 

 cultivation. The Danaid, D. plexippus and the Nymphaline 

 mimic, Hypolimnas misippus, which are so like this Cethosia
