52 et. seq. Among this family we have recorded as occurring in Sumatra all species which have been 
actually obtained in the Straits of Malacca. Worderman only records with certainty 6 species of which one, 
No. 492 Onychoprion fuliginosus, Gm. (Archipel Indien) is certainly an error. 
62 Steyna sumatrana is the species more generally known as St. melanauchen. Temm. 
65 This petrel has been obtained at Singapore and at One Fathom Bank in the Straits of Malacca and 
almost certainly therefore occurs in Sumatran Waters. : 
66-95 Charadriiformes. 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. Muller 
(Verh. Land en Volkenk, p. 153 (1839-44)) and cannot be accepted. Another, No. 438 Orthorhamphus magni- 
vostvis, Geoftr. (Asie meridionale, Java)=Cdicnemus magnirostris, Vieillot (ex Geoffr.) Nouv. Dict. d’Hist 
Nat. xxiii, p. 231 (1819), 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 S. E. Sumatra. 
No. 449 Numenius majov, Temm. (Malacca, Borneo, Java,) is a synonym of the Eastern Curlew Numenzus 
cyanopus, Vieillot. Nouv. Dict. d’Hist. Nat. viii. p. 306 (1817), 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-flats of the Straits of Malacca with one or two exceptions. 
In addition to those enumerated Dromas ardeola, Paykull, Konig]. Vet-Akad. Handl. Stockh. xxvi, 
pp. 182, 188, tab. i (1805), the Crab Plover, which occurs occasionally on the Klang Islands will probably 
also be found on the western sides of the Straits. 
96 Plegadis falcinellus (Tantalus falcinellus, Linnaeus, Syst. Nat. i, p. 241 (1766). This species is 
recorded as 478 Falcinellus igneus, Gm. (cosmopolite) by Vorderman. Though it not improbably occurs it is 
not vouched for by any authentic record. 
99 This bird is a distinct species and not a local race of the preceding. It has been collected by 
Dr. W. L. Abbott and Mr. C. B. Kloss on the Little Siak River, Eastern Sumatra. 
100 Leptoptilus dubius (Avdea dubia, Gmelin. Syst. Nat. i, p. 624 (1788), is recorded by Vorderman as 
No. 474 of his list but probably does not occur in the Malay Region. 
122 The occurrence of Phalacyocorvax javanicus (Cavbo javanicus Horsfield, Trans. Linn. Soc. xiii, 
Pp. 197 (1821) in Sumatra, recorded by Vorderman as 486 Microcaybo pygmaeus, Pall. (Borneo, Java) 
remains to be verified. 
125 Phaethon vubvicauda, Boddaert, Tabl. Pl. Enl. p. 57 (1783) included in Vorderman’s list as no. 491 
does not appear to have been obtained nearer to Sumatra than Christmas Island, where it is common. 
139 We know of no authentic record for either Milvus affinis, Gould, or Miluus govinda, Sykes, Nos. 9 
and 10 of Vorderman’s list. 
179 Alcedo beryllina, Vieillot, Nouv. Dict. d'Hist. Nat. xix, p. 414 (1818) is almost certainly confined to 
Java and certain of the lesser Sunda islands and does not occur in Sumatra (No. 107 of Vorderman’s list). 
203 Caprimulgus pallidus, Hartlaub and Caprimulgus fabevi, Meyer, Nos. 131 and 133 of Vorderman, 
have no claim to specific distinctness. 
298 et seq. Of the species listed by Vorderman 150 Cyornis sumatrensis, Sharpe; 159 Rhipidura 
phaenicurva, Mull.; 161 Rhipiduva longicauda, Wall; 162 Rhipidura salvadovi, Sharpe; and Xenogenys 
(Cochoa) azurea do not occur in Sumatra. 
334 etseq. Of the Caterpillar-Shrikes the following species are wrongly attributed by Vorderman to 
Sumatra, viz. 182 Avtamides bicolor, Temm.; 185 Graucalus javensis, Horsf; 187 Graucalus striatus, Bodd. 
N.B.—Since the above list was printed several new subspecies of Sumatran birds 
have been described and several further already-known species have been ascertained to 
occur. A list of these will be given in the final section of Part II of this Volume.
