BIRDS FROM SIAM AND THE MALAY PENINSULA 523 



ZOSTEROPS PALPEBROSA CACHARENSIS Baker 



Zosterops palpebrosa cachnrensis Baker, Ibis, 1922, p. 144 (Gujong, northern 



Cachar). 

 Zosterops palpebrosa vicinia Riley, Proc. Biol. Soc. Washington, vol. 42, p. 1G2, 



1929 (Summit Doi Sutep, Siam). 



One male and one female, summit Doi Sutep, December 15, 1928; 

 two males and one female, Doi Hua Mot, August 29, September 1, 

 1934. 



This form was described by me as Z. ^'^ vicinia as similar to Z. p. 

 palpebrosa but lighter, more yellowish above, flanks less grayish, the 

 chest suffused with, a j'^ellowish wash, with a well-pronounced yellow 

 streak down the center of the chest; wing, 54; tail, 36.5; cuimen, 

 11 mm. 



Since the original description was published, Chasen and Kloss ^^ 

 have questioned the validit}^ of the form. The tliree specimens 

 from Doi Hua Mot are molting; the new feathers appearing on the 

 throat and upperside are somewhat deeper j^ellow than the old 

 feathers, but that the three specimens belong to this form there is 

 no doubt. De Schauensee '^ secured a series at Chiengmai, Chiengdao, 

 and the southern Shan States and states that cacharensis and vicinia 

 are the same. I think he is correct, as I was originally misled by 

 Ticehurst lumping the former with palj)ehrosa. 



Deignan^^ reports it not uncommon on Doi Sutep from 3,500-5,500 

 feet. He also mentions that an unidentified species occurs on the 

 plain in winter. This is probably Z, japonica sinensis, which Dr. 

 Smith collected at Chiengmai. 



ZOSPEROPS AUREIVENTER AUREIVENTER Hiune 



Zosterops aureiventer Hume, Stray Feathers, vol. G, p. 519, 1878 (Tavoy). 



Dr. Abbott collected a male on Telibon Island, Trang, February 

 25, 1896. 



The United States National Museum also possesses a male from 

 Pulo Pintu Gedong, Selangor, October 29, 1912. 



The male from Trang is more greenish, not so yellowish above as 

 the Selangor male; below they are much alike, but the bill in the latter 

 is longer. The Trang male measures: Wing, 52.5; tail, 31; cuimen, 

 10.5 mm. The male from Selangor: Wing, 53; tail, 33; cuimen, 12 

 mm. 



Robinson " has noticed these differences and states that the bird of 

 the Malay States belongs to another form that does not go much 

 farther north than Penang, but he does not name it. Robinson and 

 Kloss '* record aureiventer from Koh Rah, Peninsular Siam.
