Cettia cantillans (T. & S.). Temm. et Schl., Faun. Japon., 1847, Aves, pl. xx, p. 52; 
Blakiston, Ibis, 1862, p. 318; Whitely, Ibis, 1867, p. 197. 
A large series of specimens collected at Fuji and elsewhere, together 
with two forms of young birds, induce me to reinstate the name of can- 
tillans, ignored of late by ornithologists, for the smaller species. I do 
not distinguish any difference of color, but there is a very great differ- 
ence in size, especially in the comparative length of the wing and tarsus. 
C. cantans measures: tarsus, 24.5™ to 25.5™™, and wing 63™™ to 65™™, 
while cantillans is 22™™ to 22.5 ™™ in the tarsus, and wing 55™™. 
This difference in size cannot be attributable to sex or season. I 
have a female of cantans measuring 9.5™™" more in the wing than adult 
male of cantillans. There is a marked difference in the young #f the 
two species, cantans, young, being 25™, cantillans 22™, in the tarsus; 
and 56™™ against 50™™ in the wing. 
Young in first plumage are the same as described under cantans, but 
have the tarsi and toes yellowish instead oi dusky.

rather rare.

This bird was taken on Fuji-Yama at an altitude of about 7,000 feet. 
It undoubtedly breeds there. It was first seen about Tate-Yama early 
in October, having been forced down from the mountains by the snow- 
storms.
