DUTCH BORNEO-EXPEDITION. 261 



Hose found a nest of this species with two young birds 

 only, we may fairly conclude that this is the full number 

 of the eggs of a clutch. 



Another (empty) nest belonging to this species, and of 

 the same construction, I found very near the top-platform 

 of the mountain, at an elevation of 1100 m., on a pro- 

 jecting boulder of a hugh rock, being protected from the 

 rain by an overhanging part of the rock just above it. 



From all we know from the few collectors who hitherto 

 chanced to meet with this species, it must be considered a 

 highland form, living along small mountain-streams in 

 rocky territory. Mr. Whitehead is the first to tell us about 

 its nesting in crevices of rocks (Ibis 1889, p. 269), while 

 Mr. Hose found his above-mentioned nest placed on a 

 tree-stump. 



This species is, up to this date, known from North and 

 North-west Borneo and the Liang Koeboeng. The above 

 mentioned young bird from Southern Borneo in the Leyden 

 Museum is hardly collected at Banjermasiu as is mentioned 

 on the label, but is most likely collected in the mountain- 

 region during Schwaner's journey across the island from 

 the mentioned place to Pontianak in West Borneo.

 Erithacus cyaneus Hose, Ibis 1893, p. 383. 



A small number of this species obtained on Mount Ke- 

 nepai 1^550 m.) in January, and on the Liang Koeboeng 

 (800 m.), March and April 2*1. This very nice little bird 

 is found in high forest as well as in low jungle, very 

 quickly running along the ground in search for insects, 

 especially white ants and their larvae. 



This species breeds in Eastern Siberia and passes the 

 winter months in more southern districts of the continent 

 and in Borneo. On this island it is recorded from Labuan 

 (Low), Kina Balu (Whitehead) and Baram District (Hose).
