1Q2 . TIMALIID^, 



spotted eggs with the one exception of T. squamatum. which lays 

 theai plain blue. Even the shape of the bills and nostrils, 

 however, varies only in degree, more or less intergrading with one 

 another. 



If Harington and Gates, and before them Gray, thought 

 it desirable to split up the genus, we have llartert on the contrary 

 lumping under the one name (lanthocincla), Gates's genera iau//iO- 

 cincla, Bahax and Troclialopterma. It must be remembered, how- 

 ever, that in the Palaearctic region Hartert has to deal with only 

 29 species and subspecies, whereas in the Orienlal region the 

 number is much greater, no less than 40 species and subspecies 

 being found in India in this genus alone. 



Gates's genera, as given in the first edition of the ' Avifauna,' 

 seem reasonable and are easy for the student to understand, and 

 I retain them in the present edition. 



In the first edition, however, many geogra])liical races were 

 quite wrongly given the status of full s[)ecies, and these are now 

 relegated to the^ir jjroper position. A few new species and sub- 

 species have been added to our list, and we have recognized in this 

 genus 12 species and 17 subspecies.

This species is a very widely extended one, ranging I'rom the 

 AVestern Himalayas to the south of Tenasserim. As might be 

 expected, its geographical variations are great, and it is therefore 

 divided into 8 subspecies.
