Dr. P. L. Sclater on the known Species of Dacnis. 
obscured. In summer a rufous tinge diffuses itself over the 
entire, bird, especially on the lores, eyebrows, and under parts, 
leaving, however, the centre of the belly nearly white. 
They leave us for the north in spring, few, if any, remaining 
to breed. 
/ 80. Anthus cervinus, Pall. 
A. pratensis japonicus, 1 Fauna Japonica* ? 
Visits Formosa in large numbers during winter, accomplishes 
its vernal moult, and leaves us in April and beginning of May. 
This transformation of the winter into the summer plumage is 
not made by a changing of colour in the feathers, but by an 
entire moult even to the quills of the wings and tail. When the 
summer plumage is completed, no traces are left of the black 
spots and streaks on the throat and breast, which become a deep 
clear vinaceous. A few streaks, however, usually remain on the 
flanks. 
y 81. Anthus richardi, Vieill. 
A very rare straggler to Formosa, though a common winter 
bird in South China.

XXVI.— Synopsis of the known Species of Dacnis. 
By P. L. Sclater. 
(Plate VII.) 
Mr. Lawrence having kindly forwarded to me for inspection 
specimens of both sexes of a new Dacnis , which he has lately 
described in the ‘ Annals of the Lyceum of Natural History of 
New York/ as mentioned anted, (p. 110), I take the opportunity 
of giving a figure of this beautiful bird, and a short synopsis of 
the species of the genus, so far as I have any knowledge of 
them. My former papers relating to the same subject will 
be found in Contributions to Ornithology/ 1851, p. 106, 
and in the f Proceedings of the Zoological Society 9 for 1854 
(p. 253).
