It is 'manifest tiiat the north-western Indian bird is not 

 the same as tiie Javan, and indeed the former bird appears 

 to run mucli larger than any other form. There are, how- 

 ever, only seven specimens upon which to base an opinion, 

 though of these no fewer than four have wings of 139 mm. 

 and upwards. Should a larger series confirm these mea- 

 surements, this race would certainly require a new name, 

 as there is none now applicable. 



Leaving the north-western form, we have a second with 

 a wing roughly averaging about 130 mm., extending from 

 Nepal through Sikkim, Bhutan, Assam north and south of 

 the Brahmapootra, the Chin, Kachin, and Shan Hills, down 

 into Siam north of the Peninsula. North Arrakan and 

 south Chin Hill birds, with wings averaging 133 mm. 

 (a larger series niigiit decrease this average), also appear 

 to belong to this form. The birds from south Arrakan and 

 the whole of west and central Burma belong to a smaller 

 form with a wing averaging 124 mm., and to this race 

 belong those from peninsular Siam and Burma with wings 

 averaging about 1 mm. longer. 



In Java itself we have a very small bird with a wing only 

 117 mm. in average length, although we have a fair series 

 (13 skins) for examination, At the same time, it is verv
