Like B. a. major but smaller: wings 75-81 
Distribution :—Tenasserim ; in the Malay Peninsula south- 
wards ; Sumatra, Java, Borneo and the Philippines. 
Both forms occur at the Pakchan where a series has been 
obtained with wings measuring 78-86 mm. Three ex- 
amples from Koh Lak, S. W. Siam have wings of 79 mm. 
and it is therefore probable that the true range of B. a. 
major does not extend southwards much beyond Tavoy. 
With regard to the specific name Oberholser has pointed 
out (Proc. U. 8. Nat. Mus. 52, 1917, p. 193 that Lanius 
melanocephalus Gm. (Syst. Nat. I, 1788, p. 308) is pre- 
occupied by Lanius melanocephalus Gm. t.c. p. 301, and 
that the next available name is Turdus atriceps Temm., PI. 
Col. No. 147, 1822 Java and Sumatra. 
The following alterations are necessitated :— 
p. 425. Microtarsus melanocephalus fusciflavescens to Brachy- 
podius atriceps fusciflavescens. 
Microtarsus poiocephalus to Brachypodius poiocephalus. 
p. 426. Microtarsus cinereoventris to Brachypodius cine- 
ventris. 
p. 457. In Pnoepyga the sexes are said to differ: this may be 
the case in the Indian forms but not for the genus as a 
whole. In Malayasian birds, at any rate, it is impossible to 
constantly separate males from females (cf. Journ. Fed. 
Malay States Mus. VIII, pt. 2, 1918, p. 204).
