STERNA LONGIPENNIS (Blanford, Vol. IV., p. 319; see 
Legge, p. 1016). 
Nordmann’s Tern. 
Description.—Similar to that of S. fluviatilis, save that the 
bill and feet are always blackish and slightly smaller, the 
bill in the present species being only 1°75 from the gape as 
against 2. 
Distribution —One example shot by Capt. Legge at Trinco- 
malee in June, and classified by him as S. fluviatilis, is now in 
the British Museum, and has been assigned to the present 
species, which ranges from North-eastern Asia to New Guinea, 
and has been obtained in the Malay Peninsula. 
STERNA DOUGALLI (Blanford, Vol. IV., p. 319; 
Legge, p. 1033). 
The Roseate Tern. 
Description —Summer: A black cap from the bill to the 
upper part of the hind neck, coming down the sides of the 
head to the lower edge of the eye; remainder of the hind 
neck white, shading into the pearl-gray of the upper plumage ; 
primary quills a little darker with some black; all the 
primaries and secondaries have a white inner border. The 
tail is a little paler than the back, and the long outer tail 
feathers are almost white throughout. The under parts are 
white with a roseate tinge. 
In winter the top of the head forward of the eyes is white 
with black spots, while the rosy hue almost disappears from 
the under parts. Immature birds resemble adults in winter, 
but the black cap is tinged with brown ; the upper parts are 
white banded with brown, and the darker parts of the primaries 
are dark gray instead of black. 
Bill in summer orange-red at the base, remainder black, in 
winter almost all black ; iris dark brown ; legs and feet coral- 
red or scarlet. 
Length about 15 ; wing 8°75; tail 5°5-7°5 ; depth of fork 
4-5 ; tarsus °85 ; bill from gape 1:90. 
Distribution.—Occasionally seen in fairly large numbers at 
various points on the coast. Occurs in the Andamans, but
