BIRDS FROM SIAM AND THE MALAY PENINSULA 305 



green. New green feathers are just emerging from their sheaths on 

 the pectoral tracts and thighs. 



This jay has been reported nearly all over Siam proper, except the 

 southeast, where C. h. hypoleuca seems to replace it. Robinson and 

 Hoss ^^ record a male from Hat Sanuk, which is about as far in this 

 direction as I have seen any records. De Schauensee ^^ in recording 

 it from Chiengrai and Chiengmai, says that during the winter he 

 neither saw nor heard birds of this species in the hills. The species 

 is not known to be migratory, however. 



The form ranges from the Hunalayas to the extreme east of Assam, 

 eastern Bengal, Burma, Tenasserim, southwestern, northern, and 

 eastern Siam and east to northern Laos, Tonkin, and northern Annam. 



CISSA HYPOLEUCA HYPOLEUCA Giglloli and Salvador! 



Cissa hypoleuca Giglioli and Salvadori, Atti Reale Accad. Sci. Torino, vol. 20, 

 p. 427, 1885 (Thu-Dan-Mot, Cochin-China). 



One male and one unsexed, Nong Khor, November 16, 1926, and 

 February 9, 1927; one female, Nong Nam Eew, February 15, 1927; 

 one male, Nong Yang, November 13, 1931; one female, Kao Ban- 

 tad, December 23, 1929; one female, Kao Sabap, November 13, 1933. 



The above series is assigned to this form with reservations. I have 

 had a typical female from Cochinchina for comparison, and the 

 Siamese birds are a deeper yellow below with a light greenish wash on 

 the throat and chest. The Cochinchina female is cream color below, 

 with only a greenish wash on the cheeks. 



De Schauensee " in recording a female from Kao Sabap, has also 

 assigned it to this form with reservations. The female collected by 

 Dr. Smith at the same place evidently differs somewhat from the one 

 he describes in the pattern of the inner remiges. In Dr. Smith's bird 

 there is a black band above the blue subterminal band ; the tip is green. 

 The unsexed specimen from Nong Khor also has a similar black bar 

 on the inner remiges above the blue bar. The remaining specimens 

 are without this black bar, however, so it is probably only an indi- 

 vidual variation. 



Robinson and Kloss ^* have suggested that Baker's record of a 

 juvenile female from Hupbon in Herbert's collection with the under- 

 parts brilliant yellow as Cissa chinensis is this species. They are un- 

 doubtedly correct. 



C. h. hypoleuca ranges from southern Annam and Cochinchina to 

 southern Laos and southeastern Siam. C. h. chauhti Delacour is found 

 in central Annam.
