auriculars mouse gray; sides of neck like the back; chin and throat rather 
light smoke gray; breast and abdomen, dull strontian yellow, washed with 
yellowish citrine except on the middle of the abdomen; crissum dull barium 
yellow; lining of wing white, the axillars washed with barium yellow.

height of bill at base, 5; tarsus, 15; middle toe without claw, 10. 
- This race extends geographically from southern Tenasserim to the southern 
end of the Malay Peninsula. It differs from Arachnothera longirostris 
melanchima of eastern Sumatra in its lighter, more yellowish (less greenish) 
upper parts, and in the more golden hue of the yellow of the under surface. 
Arachnothera longirostris heliocrita, subsp. nov. 
Subspecific characters.—Resembling Arachnothera longirostris antelia, from 
the Malay Peninsula, but with bill smaller; upper parts darker, duller, more 
grayish or brownish, the olive green areas more greenish (less yellowish) in 
tone; and yellow of posterior lower parts slightly lighter and somewhat less 
extensive. 
Type.—Adult male, No. 170469, U. S. Nat. Mus.; Selitar, 9 miles from 
the town of Singapore, Singapore Island, Federated Malay States, May 
17, 1899; Dr. W. L. Abbott. 
Measurements of type.—Wing, 67 mm.; tail, 44.5; exposed culmen, 32.5; 
height of bill at base, 5; tarsus, 16; middle toe without claw, 10. 
This race has been noted only on the island of Singapore. It may be 
distinguished from Arachnothera longirostris melanchima, of eastern Sumatra, 
by its shorter bill; duller, less greenish (more grayish or brownish) upper 
parts; and the somewhat paler, more golden (less greenish) tint of the yellow 
of the posterior lower surface. 
Anthreptes malacensis heliolusius, subsp. nov. 
Subspecific characters.—Similar to Anthreptes malacensis wigleswortht, 
from Sulu Island, but much larger. 
Description.—Type, adult male, No. 201279, U. 8. Nat. Mus.; Basilan 
Island, Philippine Islands, January 31, 1906; Dr. E. A. Mearns. Pileum, 
cervix, back, and sides of neck, iridescent metallic bottle green with some 
purplish reflections; rump and upper tail-coverts, metallic royal purple; 
tail fuscous black, the middle feathers more blackish, and with metallic 
purple sheen, all the rectrices edged with metallic purple and metallic bottle 
green; wings fuscous black, with the quills edged with orange citrine; middle 
coverts, edges of greater coverts, and the scapulars, chestnut; lesser coverts 
metallic royal purple; sides of head citrine, the upper part of these narrowly 
burnt sienna; chin, throat, and jugulum, tawny, bordered laterally with 
burnt sienna; breast deep wax yellow; abdomen light dull strontian yellow; 
crissum olive yellow; sides and flanks, light yellowish olive; lining of wing 
pale grayish brown, washed with citrine. 
Measurements of type.—Wing, 68 mm.; tail, 44; exposed culmen, 16; 
tarsus, 17; middle toe without claw, 10.5. 
This form is intermediate between Anthreptes malacensis wiglesworthi 
and Anthreptes malacensis chlorigaster. The female is similar to the female of 
Anthreptes malacensis bornensis Riley, but is of a darker, more bronzy green 
above, and is much duller, more olivaceous below.
