Javan birds, A. a. n/ffinis, are certainly distinct, while it is 

 possible that the Sumatran form may be separable as A. ajjinis con- 

 color SchJeg.

"Iris dark hazel, bill black ; tomia yellow ; feet pinkish brown". 



Total length 173, wing 77, tail 40, tarsus 19, bill from gape 

 44 mm. 



There is no difference either in size or other respects between 

 specimens from Peninsular Siam, from the south of the Malay 

 Peninsula, and from N. E. Sumatra. All require comparison with 

 typical Javan birds and if distinct therefrom will have to bear the 

 name Arachnothera chrysogenys copha Oberholser, Smithsonian Misc. 

 Coll. 60, No. 7, 1912, p. 20 (N. W. Sumatra). 



556. Arachnothera flavigaster (Eyton). 



Anthreptes Jiavigaster, Eyton, P. Z. S. 1839, p. 105 (Malacca). 

 Arachnothera flavigaster, B., p. 25 (Junk Seylon) ; F., p. 78 (Trang). 

 2 S . Chong, Trang, 18-19 Dec. 1909. 



Wing 98, 103 ; bill from gape 43, 44 mm. 



These specimens do not differ in any way from three males 

 from Bukit Tangga, Negri Sembilan, which measure, wing 98-108; 

 bill from gape, 42-45 mm : Plartert (Nov. Zool. ix, 1902, p. 574) 

 mentions a male from Gunong Tahan, Pahang, 1,000 feet, with wing 

 115 and bill from gape 42 mm. 



Sumatran birds are also inseparable ; a male from Bencoolen 

 district measures, wing 107, bill from gape, 45.5, and a female from 

 the same district wing, 99, bill from gape, 40 mm,
