246 NOTES ON AND ADDITIONS TO CEYLONESE AVI-FAUNA, 
collected in the Jaffna district that they are not uncommon 
there. 
861.—Dromas ardeola, Payk. 
Literally hundreds of these usually rare species crowded the 
great tidal flats to the north of Manaar, but, having to hurry 
my canoe on to save the tide, I could do no more than have a 
passing stalk, at some little groups, which of course failed. 
862.—Hematopus ostrealegus, Linn. 
I met with this rare and wary bird on several occasions 
during my late trip to Jaffna, and succeeded in knocking over 
a fine immature bird, with white throat at the small span 
of 90 yards! I know of no other example actually procured in 
the island. 
985 bis.—Sterna Dougalli, Montague. 
The Terns noticed in “Stray Freatuers,” Vol. III1., p.376, were 
correctly identified as belonging to the above, and not to Sterna 
paradisea, Bonn,* which is the Arctic Tern. Mr. Saunders has 
since determined that the birds procured at the Andamans be- 
longed to the latter species. It is a mystery where all the 
flocks, I saw, departed to, they began to pair rapidly at the 
beginning of June, and disappeared altogether in about a fort- 
night after that. 
988 ter.—Sternula sinensis, Gmelin. (S. placens, 
Gould) 
This is the common little Tern of Ceylon and ranges I believe 
by Java and Sumatra to the seas of the north coast of Australia. 
* Some confusion exists here. In the first place S. paradisea, Briin. not Bonn 
is probably intended. In the second place our Andaman Terns are by no means 
the Arctic Tern. 
I think the explanation is this; Sterna paradisea, Briinn, Orn. Bor. 42 
(1746,) is by some ornithologists still considered to refer to the same species as 
Montague’s S. Dougalli. Orn. Dict. suppl. (1813). Others and probably the majority 
of modern ornithologists hold that Briinnich’s name is applicable to the Arctie Tern, 
now usually accepted as S. hirundo, Lin, with macrura, Naum, and arctica, 
Tem, as Synonymes. When Lord Walden reported, Ibis, 1874, p. 149, that Mr, 
Howard Saunders had identified the Andaman Terns with S. paradisea, Briinn, he 
unquestionably used the name as I did (S. F., II. p. 601) as equivalent to S. Dow- 
galli, and not in its more modern acceptation of the Aretic Tern. Lord Walden’s re- 
marks “ lower surface deeply suffused with a rosy salmon tint” sufficiently dispose of this 
question. Perhaps Lord Walden does not concur in the more modern acceptation ; 
very likely at the the time he wrote, Mr. Saunders had not yet made up his mind 
on the subject; but be this as it may, the fact remains that the Andaman speci- 
mens referred to by both Lord Walden and myself (loc. cit) were (if not gracilis 
Gould, and for this Mr. Saunders is responsible) the Roseate and noé the Arctic 
Tern, i.e, the same species as occurs in Ceylon.—Ep.,, S, F
