112 A COLLECTION OF BIRDS FROM X. E. SUMATRA. 



Birds from Borneo, Sumatra, and the Malay Peninsula do 

 not seem to differ. We have not examined specimens from 

 Java, which is the typical locality. 



154. Pycnonotus bimacuIatus(Horsf.). 



Eobinson and Kloss, p. 180. 



2 $ , 9 , Brastagi, Simeloengan, 1ST. E. Sumatra, 21st 

 June 1917 [Xos. 533-5]. 



Wing, 4, 80; $, 78, 8-1 mm. 



The specimens are rather immature but are not separable 

 from typical West Javan and West Sumatran birds; they are 

 rather lighter below than any of a large series from Korinchi 

 and the Preanger Regencies but this is probably a character 

 of age. The East Javan form P. ~bimaculatus tenggerensis is 

 slightly different in having the ear coverts less extensively 

 washed with yellow. 



155. Pycnonotus aurigasfer(Yieill). 



Pycnonotus aurigaster, Sharpe, Cat. Birds Brit. Mus. VI, 



p. 137 (1881). 

 $ , 2 , Polonia, Deli, X. E. Sumatra, 18th November 



1916 [Xos. 720, 745]. 

 Wing, $, 95; $,89 mm. (worn). 



We have compared these birds with typical specimens 

 from Western Java with which they agree. The species has 

 not hitherto been recorded from Sumatra but has not impro- 

 bably been introduced from Java, (vide portea p. 61). 



156. Pycnonotus analis(Horsf.). 



Robinson and Kloss, p. 179. 



Pycnonotus goiavier analis, Hartert, p. 210. 



3$, 4 2, Polonia, Deli, X. E. Sumatra, 22nd April 



1916—26 March 1917 [Xos. 148, 779. 180, 673, 



792, — — ].

April 1917 [No. 315]. 

 Wing, $ , 81, 86, 85, 82 (worn) ; 9 , 82, 81, 86, 82 mm. 

 Malayan, Bornean, Javan and Sumatran specimens all 

 seem inseparable.

May 1917 [Nos. 357-8].
