A COLLECTION OF BIRDS FROM N. E. SUMATRA. 123 



202. Poliositta azurea expectata(Hartert). 



Eobiuson and Kloss, p. 228. 

 2 , Tengkeh, Simeloengan, N. E. Sumatra, 20th June 



1917 [No. 526]. 

 Wing, 75 mm. 



A form very slightly differentiated from the typical Javan 

 race. The Malayan and Sumatran birds are identical. 



203. Corvus enca compilator, Richmond. 



Robinson and Kloss, p. 229. 



Corvus enca, subsp., Hartert, p. 215. 



2, Deli Toewa, Deli, N. E. Sumatra, 5th April 1917 

 [No. 214]. 



$ , Toentoengan, Deli, N. E. Sumatra, 7th March 1918 

 [No. 1030]. 



Wing, a, 318; 2, 305 (worn) mm. 



Distinguishable from the heavy-billed O. macrorhynchus, 

 Wagl., which probably also occurs in Deli, by the poorly deve- 

 loped, almost absent, throat hackles and by the greyish colour 

 of the undersurface. 



204. Dendrocitta occipitalis (S. Muell.). 



Robinson and Kloss, p. 230 • Hartert, p. 215. 



3 <£ , 2 2 imm., Bandar Baroe, Deli, N. E. Sumatra, 12th 



April— 10th June 1917 [Nos. 238-9, 270, 473]. 

 Brastagi, Simeloengan, Deli, N. E. Sumatra, 21st June 



1917 [No. 531]. 



S , Tengkeh, Simeloengan, N. E. Sumatra, 29th June 



1918 [No. 1047]. 

 No exact locality. 



Wing, $ , 141, 138, 138, 135, 138; 2 , 143, 143, 134 mm. 



This series in no way differs from specimens from the 

 west coast. Young birds have the undersurface very much 

 lighter and the feathers of the back and rump, especially the 

 latter, tipped with fulvous buff. 



205. Cissa chinensis minor (Cab.). 



Robinson and Kloss, p. 231. 

 $ 2 , Bandar Baroe, Deli, N. E. Sumatra, 10th June 1917 



[Nos. 487, 488]. 

 2 , Tengkeh, Simeloengan, N. E. Sumatra, 17th June 



1917 [No. 491]. 

 2 , Brastagi, Simeloengan, N. E. Sumatra, 19th June 



1917 [No. 492]. 

 Wing, $ , 130; 2, 126, 127, 137 mm. 

 Extremely closely allied to the forms from the Malay 

 Peninsula, (C. c. robinsoni, Grant) and from Tenasserim (0. 

 c. chinensis). Much more distantly related to that from Java 

 (C. thalassina).
