3. On an apparently new Species of Duck (Dafila) from the 
Central Pacific. By H. B. Tristram, D.D., F.R.S. 
[Received November 14, 1885.] 
(Plate VII.) 
I lately received a small parcel of birds collected by Mr. J. V. 
Arundel, at Sidney Island, Phoenix Group, lat. 4° 30'S., long 171° 20! 
W. The island, which is a mere coral-lagoon island, has never, so far 
as I know, been visited by any naturalist. But, alas, Mr. Arundel 
was not able to discover any land birds whatever, beyond Charadrius 
JSulvus and Totanus incanus. He has, however, sent three specimens, 
one male and two females, of a Duck which appears to be hitherto 
undescribed. The only note I have respecting it is, that there were 
no Ducks on the island on Mr. Arundel’s arrival, but that afterwards 
they appeared, and were tolerably numerous for a time. I gather 
from this remark that it is probably a migrant from one island to 
another; and a glance at the position of Sidney Island on the map 
will show that a Duck may enjoy a considerable range of migration 
in those regions, without necessarily coming under the eye of a col- 
lector. It is now nine years since Dr. Streets described a new 
Gadwall from Washington Island (Bull. Nuttall Club, i. p. 46), and 
yet the species has not since that time been met with, 
The bird before us is a plain-coloured Pintail of diminutive size. 
The male specimen is just discarding the young or summer dress, 
and assuming the delicately vermiculated and pencilled plumage of the 
flanks and back which characterize our own Pintail in breeding-dress. 
On the flanks only two or three young feathers remain. 
I propose to name it, from its extreme simplicity of plumage, 
DaFILa MODESTA, sp. nov.
