122 A COLLECTION OF BIRDS FROM N. E. SUMATRA. 



This species varies much in colour according to the age 

 of the plumage; freshly moulted birds have the flanks and 

 rump rich rufous buff while worn birds hae them almost 

 white. Young birds have the whole of the upper surface dull 

 rufous buff the feathers edged with blackish and with no trace 

 of the black frontal band. Beneath the flanks are pale ful- 

 vous the feathers with dark edgings.

 A common species throughout the Indo-Malayan Region 

 though full plumaged males with grey head and deep black 

 eye-streak are always greatly in the minority.

3 $ , 5 $ , Polonia, Deli, X. E. Sumatra, 24th October 



1916— 26th February 1917 [Xos. 77, 75, 691, 715, 

 717, 723, 801]. 



Wing, 3 , 8-1, 82, 88 ; $ , 83, 83, 84, 85 mm. 



The shrikes of this group are most difficult birds to dis- 

 criminate. Three races occur in the Malayan area viz., L. c. 

 cristatus, Linn., a pale bird with no strong cinnamon on the 

 flanks and no very strongly marked supercilium or pale frontal 

 area; L. c. superciliosus a richer coloured bird usually with a 

 pale frontal band, and L. c. lucionensis in which the back and 

 rump is clay colour and the grey of the forehead extends over 

 the crown. The present series presents intermediates and pos- 

 sibly all three forms are represented but we have thought it 

 best to record all as L. c. superciliosus the type of which came 

 from Batavia. 



201. Parus cinereus malayorum, Eob. and Kloss. 



Eobinson and Kloss, p. 226. 



$, Brastagi, Simeloengan. X. E. Sumatra, 21st June

Wing, 64 mm. 



Apparently common at considerable elevations in Sumatra 

 as in Java. In the Malay Peninsula it is only found among 

 the Mangroves and Casuarinas on the coast.
