Malacca, Singapore, and Sumatra. I have compared my 

 specimen and an unsexed skin from Bangkok (coll. H.R.H. 

 Prince Chumporn) Avitli birds from tiie Malay States, 

 Singapore, and the Rhio Archipelago, and find that the 

 upper parts of the Siamese birds are a less rich, brown, 

 being paler and duller on back and wings, and that the 

 heads are paler and greyer. 



I find that two forms occur in the Malayan localities 

 mentioned : — (1) a smaller bird with richly-coloured under- 

 parts, having the wing in males (6 examples) 183-193, 

 females (3 examples) 186-198 mm. ; and (2) a larger race 

 with the brown element less extensive below, and having 

 wings in males (3 specimens) 210-216 mm. and females 

 (2 specimens) 218 mm. The larger birds were obtained in 

 the winter months on the mountains of the Malay States 

 and on Pulau Jarak, an islet in the middle of the Straits of 

 Malacca, and are probably examples of iV. s. scutulata 

 Raffles \_N. s.japonica (Temm. & Schleg.)]. 



Both subspecies are similar in colour above ; but in the 

 smaller the brown markings on the flanks are broader and 

 more bar-like, whereas in the larger they more nearly 

 approach longitudinal streaks : these are the distinguishing 

 characters recorded by Grant ('Ibis,' 1896, p. Ill; for the 

 Indian N. scutulata and N.japonica (T. & S.). 



The Siamese birds have the lighter underparts of the 

 larger race, but the flank-markings are intermediate in 

 shape.
