in pairs. In the note to his article on Motacilla proregulus, 
Pallas also alludes to the R. modestus, doubting whether a bird 
of this last species received from the banks of the Lena, and 
which he had referred to Motacilla acredula, L., might not be the 
female of his M. proregulus. Such a doubt has probably 
entered the head of every field-naturalist on first encounter¬ 
ing the two species, but a careful study of the two birds soon 
dispels it. Let us turn to page 497, under the head “ Motacilla 
acredula 33 (i. e. probably the Chiff-chaff, Sylvia rufa, Lath.). 
We find, in a note, mention made of the birds observed by 
M. Schmid on the Lena, which he had briefly described in 
a MS. as ({ Reguli non cristati, omnium forte minimi. 33 These 
were doubtless the R . modestus; but as no name was there sug¬ 
gested for them, we must look elsewhere for a title for our 
interesting little friend. 
In winter it is not uncommon about woods and groves in 
Formosa, its loud single call-note, “ sweet 33 always attracting 
attention to its presence. It is very rarely in company with 
others, is lively and constantly in motion in pursuit of its insect- 
food, and seems to be entirely happy in its own resources. 
A comparison of skins has amply proved that the birds from 
China, Formosa, and India are one and the same, and identical 
with the little Dalmatian (so-called) stranger procured on the 
coast of Yorkshire.

This species, which can at once be distinguished from the two 
other Pied Wagtails of Southern China by its white face and 
want of black line through the eye, is a resident bird in Formosa. 
It is also smaller, and has a longer bill. There is much white 
on the wings. In summer the back becomes entirely black, and 
the black on the breast extends close up to the chin, within half 
an inch of the bill. Its eggs are very similar to those of the 
Pied Wagtail of England.

I procured one specimen of this in March, after a heavy gale.
