While Schrenck's R('P(l-^\ arbler was missing from the 

 eastern slope of Fuji^ it was remarkably common a little 

 further round on the north-eastern side, from Lake Yamanaka 

 upwards for about fifteen hundred feet. Although found by 

 the lake-side, the presence of water seemed l)y no means 

 essential to its welfare, for the l)ird was ecjually plentiful 

 amongst the rough grass and scrub three or four miles up 

 the mountain aiul in phiccs where there was no water of any 

 kind. At times the whole country-side resounded with its 

 song, which bore a distinct resemblance to that of certain 

 other members of the genus. It was obviously imitative. 

 Part of a Skylark's melody would be coupled with the notes 

 of a Grey-headed Bunting, while these, in turn, would be 

 followed by a little of the Stonechat's song — all the birds 

 mimicked being common in the same neighbourhood. When 

 singing the male will climb to the point of an upstanding 

 twig or plant-stalk, and there display itselt as conspicuously 

 as its sober plumage will allow. 



This Warbler had not commenced to breed by June 4th.

This bird is apparently of very local distribution, fori only- 

 found it within a limited area on Fujiyama. It is essentially 

 a sylvan species, and never wanders far from the depth of the 

 woods, where, owing to its habit of keeping to the under- 

 growth, it is extremely difficult to observe. The song is a 

 shrill impulsive zi, zi, zi, zi, uttered in a high key. On 

 May 23rd a nest containing seven eggs, slightly incubated, 

 was discovered in a partial clearing of the forest, hidden under 

 the roots of an old upturned tree-stump. It was an open
