B. t. shanensis differs from the preceding form in having the 

 rufescent-brown portions of the plumage replaced by olivaceous- 

 brown; the ashy-gray portions replaced by ashy white; the dark 

 spots on the throat fewer and rather less conspicuous. 



BRADYPTERUS LUTEOVENTRIS TICEHURSTI Deignan 



Burmese Buff-breasted Bush Warbler 



Bradypterus luteoventris ticehursti Deignan, Proc. Biol. Soc. Washington, vol. 

 56, 1943, pp. 70-71. New name for Tribura luteoventris saturatus [sic] Tice- 

 hurst, Ibis, 1941, pp. 318-319 ("Thayetruyo-Minbu border, 5000 feet, Southern 

 Chin Hills"), not Tribura thoracica saturata Yen, 1933. 



The one imperfect specimen of Bradypterus luteoventris known 

 from Thailand is an unsexed example from Doi Suthep, 3,300 feet, 

 March 23, 1937; the circumstances surrounding its discovery have 

 been fully related in the account of Bradypterus t. shanensis. 



It has the entire upperparts chestnut-brown; the indistinct super- 

 cilium buff; the underparts (including the under tail coverts) brown- 

 ish buff, becoming white on the chin, throat, and center of the ab- 

 domen (unspotted, but with the slaty bases of the feathers sometimes 

 showing through on the throat and breast). 



My bird is so distinct from one specimen of luteoventris and seven- 

 teen of russulus and agrees so well with Ticehurst's description of 

 his saturatus that I have no choice but to place it with this putative 

 Burmese race, which probably has a more southerly distribution 

 than luteoventris.

The pied wagtail, represented in our provinces by at least four forms, 

 is an abundant winter visitor throughout the northern lowlands except 

 in forested areas. Specimens of the present race (which is certainly 

 the commonest with us) have been taken in the provinces of Mae Hong
