Similar in all respects to 8. cheela, but very much smaller, appear- 

 ing to be a southern representative of that bird. A specimen from 

 Hainan, one of the types of S. nitherfordi, measures : — total length 

 27 inches, wing 17'8, tail 11, tarsus 3-8. The colour is rather 

 duller brown than in other Indian examples. With the above di- 

 mensions may be compared a bird from Murshedabad : — total length 

 25 inches, wing 16-8, tail 10-8, tarsus 3-65. Mr. Hume gives the 

 following measurements of his new Andaman species, S. davisoni 

 (?) : — total length 24 inches, wing 15 inches; and I believe that 

 a gradual gradation may be found. The uniform chest, which some 

 naturalists think a distinguishing character, exists in fully adult 

 birds of S. cheela from the Himalayas. It is possible that S. pal- 

 lidus may some day be united as a further diminutive race of the 

 southern form ; but its extremely small size and pale coloration induce 

 me at present to keep it distinct.

 lon, extending eastwards through the Indo-Chinese countries to
