Cyornis magnirostris caerulifrons Stuart Baker. 



Ci/ornis ina(j7iirostris cicrnllfrous Stnart Baker, Bulk Brit. 

 Ornith. Club, xxxix. 1918, p. 8 : Kloiig 13an<j; Lai, peninsular 

 Siani. 



Recently described from specimens collected at FClong 

 Bang Lai. The present author also obtained a single male 

 example in the mountain regions west from Koh Lak in 

 south-western Siam. Specimens from Trang most certainly 

 belong to this race, though they have been recorded under 

 the heading of Cr/orms magnirostris. 



Cyornis pallidipes hainana Grant. 



Siplda hainana Grant, Bull. Brit. Ornith. Club, x. 1900, 

 p. 36 : Five Finger Mounts, 0. Hainan. 



The specimens of the White-bellied Blue Flycatcher 

 recorded from Siam most certainly all belong to the form 

 described from Hainan. Unfortunately only males have 

 been obtained, and as the differences between the typical 

 form and that from Hainan are very slight and only notice- 

 able in the females, it has been impossible to definitely state 

 to which subspecies the Siamese birds belong. In Siam 

 it has hitherto only been met with by Kloss and myself at 

 Koon Tan, Pak Koh (N. Siam), and at Lat Bua Kao and 

 Klong Menao in the eastern districts. 



Cyornis oatesi Salvad. 



^iltava oatesi Salvadori, Ann. Mus. Civico Genova, (2) 

 1887, p. 514 : Mooleyit, Tenasserim. 



Hitherto only recorded from Koon Tan ia northern 

 Siam. 



Cyornis cyaneus Hume. 



Musc'itrea c//anea Hume, Stray Feathers, v. 1877, p. 101 : 

 Tenasserim. 



Stated in the Cat. Birds Brit. Mus. vol. viii. 1883, p. 225, 

 to inhabit Siam, but nothing else is known about its occurrence 

 in that country, and no recent collector has ever met with 

 it there.
