368 MESSRS. ROBINSON AND KLOSS ON 



Williamson obtained a specimen afc Naihut, Langsuan, Penin- 

 sular Siam on 29 October 1921 : this is the most southerly occurrence 

 on record in the Peninsula. 



In view of Meinertzhagen's remarks on the forms of Anthus 

 richardi (Ibis, 1921, pp. 651-655) we are a little doubtful about the 

 determination of the large birds of Siam that we have seen. His 

 measurements for the three forms that occur in Eastern Asia are : — 



The long hind-claw excludes reference to striolatus, whereas 

 the wing seems too short for richardi. They may possibly be 

 sinensis which, according to La Touch e, leaves Yunnan for the South 

 in October and returns in April. It has been obtained in Hainan and 

 the Philippines in winter. 



Anthus richardi striolatus Blyth.

If the above references of three birds from South Tenasserim 

 to striolatus are correct, the form should occur in S. W. Siam : 

 Gyldenstolpe records it from N. Siam.
