306 Mr. R. Swinhoe on Formosan Ornithology. 
68. Calamoherpe canturians. 
Arundinax canturians , Swinhoe, Ibis, 1860, p. 52. 
This bush-loving species, common in China (from Canton to 
Shanghai), is also found in Formosa. Indeed, it was in Formosa 
that I first discovered the species in 1856. I for a long time 
thought that this was merely the S. cantans of the f Fauna 
Japonica/ but my late visit to the Leyden Museum has decided 
this question in the negative. 
( S, shot at Tamsuy, 6th March, ] 862. Length 6*6 in.; wing 3; 
tail 3. Its gizzard contained Diptera and larvse. 
It appears to be with us a resident species, as I have procured 
specimens in winter as well as in summer. It creeps about the 
hedges much in the manner of Sylvia cinerea of Europe, and 
utters a warning note, when approached, a good deal resembling 
that of that bird. Its song is a short trilling note, sweet, but 
never varied. 
69. Calamoherpe minuta. 
Arundinax minutus, Swinhoe, Ibis, 1860, p. 52. 
This miniature of the above is also a bush-frequenting bird, 
but of livelier habits. It is quite distinct from Salicaria can- 
tillans of the ‘ Fauna Japonica/ I have repeatedly procured it at 
Amoy in spring ; but I have reason to think that in South China, 
as in Formosa, some stay all the year through. It suspends 
its pretty nest between the stalks of grasses and reeds. It is 
formed of grasses and fibres, lined with finer materials and cat¬ 
kins. The inside cup is very deep, and usually contains five 
clear greenish-blue eggs, averaging *64 by *5 in. When disturbed 
on its nest, the bird flies to an adjoining tree, hiding itself among 
the foliage, but continuing to repeat an impatient “ churr ” note 
until the intruder moves away. 
70. Phyllopneuste fuscata. 
Phylloscopus fuscatus, Blyth. 
Sylvia [Phyllopneuste) sibirica, Middendorff, Sibirische Reise, 
p. 180. 
This brown Siberian species of the Willow-Wren group appears 
in winter to spread itself all throughout India and China, and a 
few find their way during that season even to Formosa.
