1 (J , 2 ? . Koh Lak 



Iris dull blue or grey ; bill black, base of mandible flesliy ; 

 feet plumbeous-browu or blackisli-browu. 



Male: T. L. 200; W. 84.' 



Females: T. L. 212, 202, 202; W. 85, 84, 80. 



A comparison of these birds and others from Bangkok 

 and peninsular Siam (typical locality) with examples of 

 P. b. blanfordi from Upper Burma (typical locality) 

 and Chiengmai, northern Siam (coll. K. G. Gairdner), 

 shows that they differ in having the breast rather paler, 

 the abdomen considerably washed with yellow [" baryta 

 yellow ") and the under tail-coverts brighter ; also there 

 is perhaps a rather stronger tinge of olive in the upper- 

 parts. 



• 4-83. Otocompsa flaviventris minor, subsp. nov. 



Otocompsa flaviventris Robinson, Ibis, 1916, p. 747. 



1 ? ad. Koh Lak, S.W. Siam. 16 November, 1916. 



Iris yellow ; bill and feet black. 



Smaller than O.f. flaviventris (Tickell) of Chota Nagpur; 

 wing 83 mm. or less. 



This form occurs throughout the Malay Peninsula, where 

 the examination of a large series shows that the wing-length 

 ranges between 77 and 82 mm. ; and it probably extends 

 through south-eastern Siam (where I obtained a large series 

 in 1914-15, of which no measurements have been recorded) 

 to Cambodia and Cochin-China.
