Type.—Adult male, No. 179405, U. 8. Nat. Mus.; Pulo Bangkaru, Banjak 
Islands, Barussan Islands, western Sumatra, January 18, 1902; Dr. W. 
L. Abbott. 
Measurements of type.—Wing, 51.5 mm.; tail, 45; exposed culmen; 15.5; 
tarsus, 13.3; middle toe without claw, 13. 3. 
This race is sufficiently different from the four other subspecies found on 
the various islands of the Barussan chain to be worthy of recognition by 
name. From Aethopyga siparaja niasensis, of Nias Island, it may be dis- 
tinguished as from Aethopyga siparaja siparaja; from Aethopyga siparaja 
tinoptila, of Simalur Island, by somewhat larger size, less extensively blackish, 
and less purely grayish (more olivaceous) posterior lower parts; and palit 
anterior upper and lower parts. 
Aethopyga siparaja heliogona, subsp. nov. 
Subspecific characters.—Similar to Aethopyga siparaja eupogon Cabanis, 
from Borneo, but smaller, and male with more extensively blackish, and less 
olivaceous (more purely grayish) posterior lower parts. 
Type.—Adult male, No. 219086, U. 8. Nat. Mus.; Depok, Java, March 
29, 1909; William Palmer. 
‘Measurements of type.—Wing, 49.5 mm.; tail, 41; exposed culmen, 14.5; 
tarsus, 13.5; middle toe without claw, 13. 5. 
With the addition of the above Heatiibed races, the forms of Aethopyga

Island, Barussan Islands, western Sumatra. 
3.—Aethopyga siparaja melanetra Oberholser. Pulo Lasia and Pulo 
Babi, Barussan Islands. 
4.—Aethopyga siparaja heliophiletica Oberholser. Banjak Islands, Barus- 
san Islands. 
5.—Aethopyga siparaja niasensis Hartert. Nias Island, Barussan Islands. 
6.—Aethopyga siparaja photina Oberholser. Pagi Islands, Barussan 
Islands. 
7.—Aethopyga siparaja heliogona Oberholser. Java. 
8.—Aethopyga siparaja eupogon Cabanis. Borneo. 
9.—Aethopyga siparaja ochropyrrha Oberholser. Anamba Islands. 
10.—Aethopyga siparaja lathami (Jardine).6 Central Malay Peninsula, 
from about 10° north latitude to about 5° north latitude. 
11.—Aethopyga siparaja heliotis Oberholser. Mergui Archipelago. 
12.—Aethopyga siparaja nicobarica Hume. Nicobar Islands. 
13.—Aethopyga siparaja cara Hume. ‘Tenasserim and Siam. 
14.—Aethopyga siparaja viridicauda Rothschild. Shan States. 
15.—Aethopyga siparaja andersoni Oates. Burma. 
16.—Aethopyga stparaja seheriae (Tickell). Bengal to Assam. 
17.—Aethopyga siparaja miles (Hodgson). Nepal. 
18.—Aethopyga siparaja goalpariensis (Royle). Northwestern Himalaya. 
6 Nectarinia Lathami Jardine, Nat. Hist. Nectariniadae, 1843, p. 233 (‘‘some part of 
Continental India’’). This was described from a specimen the exact locality of which is 
unknown, but the characters fit the bird from the Central Malay Peninsula, We there- 
fore designate the Malay Penisula at 7° north latitude as the type locality.
