48. The material on which the Sumatran record of Porzana pusilla 
pusilla (Pall.) is based on a specimen collected in the Padang Regencies at 
Koto Gadang (Salimpasing) on 15th January 1914 by Heer E. Jacobson. 
53. WHartert (Vog. palaarkt. Fauna, 1921-2, p. 1851) states that Fulica 
lugubris Mill., is based on an imperfect specimen and is synonymous with 
F,a, atva Linn. (Syst. Nat. I, 1758, p. 152. Sweden). 
54 The Water-Cock, Gallicrex cinerea almost certainly occurs in 
Sumatra as stated by Sharpe (Cat. Birds Brit. Mus, XXIII, p. 183) though we 
can find no definite authority. It is included in Vorderman’s list as Gallievex 
cristata, Lath. without number and with a (?). 
55. Heliopais personata. This has been obtained by de Beaufort 
and de Bussy in the Medan District, and by Jacobson in West Sumatra. 
57-69. Laridae. Of this family we have recorded as occurring in 
Sumatra all species which have been actually obtained in the Straits of 
Malacca. Vorderman only records with certainty six species: of which one, 
No. 492 Onchoprion fuliginosus Gm. (‘‘ Archipel Indien’’), is certainly an error. 
57. Hydrochelidon leucoptera. If Malaysian birds are distinct 
from those of Eurcpe they must probably bear the name H. /. grisea (Horsf. 
Trans. Linn Soc. XIII, 1821, p. 199, Java). 
58. Geochelidon nilotica. If Malaysian birds are distinct from the 
typical N, African form they must be known as G. 1 affinis (Horsf. Trans. 
Linn. Soc. XIII, 1821, p. 199, Java). 
59. Sterna hirundo tibetana. We have recorded Sumatran birds 
by the name given to the Asiatic form; but (fide Hartert, Vog. palaarkt. 
Fauna, p. 1702) the typical European race also occurs in Malaysia in the 
winter. 
60. Sterna dougalli. According to Hartert (Vég. palaarkt. Fauna, 
p-. 170) Malaysian birds if they are regarded as distinct from the typical 
race should be called S. d. bangsi Mathews (Birds of Australia, II, 1912, p. 364, 
Foochow, China). 
62. Sterna bergii. Stresemann (Nov. Zool, XXI, 1914, pp. 57-59) 
and Oberholser (Proc. U. S. Nat. Mus. 49, 1915, pp. 515-526) have both 
reviewad the races of this Tern. According to the former Sumatran birds 
should be called S. b. cristata Stephens (Shaw’s Gen. Zool. 13, 1826, p. 146, 
China) ; the latter considers them to be S. b. pelecanoides King (Survey Intertrop. 
Coasts Austr. II, 1826, p. 422, Torres Strait) which Stresemann regards 
as synonymous with S. b. cristata. 
70. Oceanodroma m. monorhis. This petrel has been obtained at 
Singapore and at the One Fathom Bank in the Straits of Malacca ard almost 
certainly therefore occurs in Sumatran Waters. 
71-98. Chardriiformes. In this group Vorderman records with 
certainty only 14 species of which one, Himantopus leucocephalus, Gould (P.Z.S. 
1837, p. 26) rests on a casual mention of Sumatra by Sal. Miiler (Verh. 
Land-en Volkenk, 1839-44, p. 153) and cannot be accepted. Another, No. 438 
Orthorhamphus magnivostvis, Geoffr. (Asie meridionale, Java) =Oedicnemus magni- 
vostvis, Vieillot (ex Geoffr., Nouv. Dict. d’Hist Nat. XXIII, 1819, p 231) rests 
on no sufficient authority, though as it has been found on the Mergui Ids. and 
on Pulau Bintang in the Rhio Archipelago it will almost certainly be found 
ultimately in E, Sumatra. No. 449 Numenius major, Temm. (Malacca, Borneo, 
Java,) is a synonymn of the Eastern Curlew Numenius cyanopus, Vieillot. (Nouv. 
Dict. d’ Hist. Nat. VIII, 1817, p. 306) which does not extend to the Straits of 
Malacca though it is sometimes met with in Borneo and Java. 
As regards our own list we have recorded as Sumatran most of the species 
that are found on the mud-fiats of the Straits of Malacca with one or two 
exceptions. 
In addition to those enumerated Dyomas arvdeola, Paykull (Konigl. Vet- 
Akad. Handl. Stockh. XXVI, 1805, pp. 182, 188, tab. I) the Crab Plover, 
which occurs occasionally on the Klang Islands off the Selangor coast will 
probably also be found on the western sides of the Straits.
