often in thorn bushes, and laying four eggs quite corvine in their 
general appearance. 
5. PLATYSMURUS LEUCOPTERUS (Temm.). 
Glaucopis leucopterus, Temm, pl. Col. No, 265 (1824), 
¢ 2 Klong Bang Lai, P. Siam, 31. 1. 1916. 
2 Klong Wang Hip, P. Siam, 6. 10. 15. 
All three of the specimens obtained by Mr. Herbert are very 
large birds with wings over 203 mm.

All three of these specimens belong to this sub-species, having 
their wings, the male 108 mm. and the females 95 and 102 mm., respect” 
ively. M. s. sultanea has a wing between 110 and 115 mm. Flavo- 
cristata forms a very poor sub-species.

It should be noted that birds from the Shan States and Annam 
are far nearer to G. |. belangeri than to the conspicuously white-bellied 
birds from Siam, and the specimens from the former countries in the 
British Musium labelled diardi should all rather be referred to belan- 
yeri. Roughly the distribution of the three races appears.to be as 
follows :— 
Garrulaw 1. lencolophus. India, Assam, Manipur, Arrakan and 
North Chin Hills. 
Gl. belongeri. Yunnan, N. and 8. Shan States, Annam, Lower 
Chin Hills, Pegu and Tenasserim. 
G.l. diardi. Extreme South Yunnan, Siam, Cambodia and 
Cochin China, rarely extending into Kastern Tenasserim, and then in 
a somewhat intermediate form approaching belangeri.
