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



3 2 Tandjong Morawa, Deli, N! E. Sumatra, 27th 

 February 1917 [No. 80]. 



S Deli Toewa, Deli, N. E. Sumatra, 4th April 1917 [No. 

 218]. 



2 $ , no details, 16th May 1916— 11th October 1916. 



$ Toentoengan, Deli, N. E. Sumatra, 7th March [No. 

 1032]. 



These specimens vary a good deal inter se but we think 

 are best recorded as the pale race originally described from 

 Borneo. Two, however, distinctly approach the darker form 

 from Java Spilornis h. bido (Horsf.). Similar birds are oc- 

 casionally met with in the Malay Peninsula. 



29. Machaerhamphus alcinus, Westerm. 



Sharpe, Cat. Birds Brit. Mus. 1, p. 342 (1874). 

 2 Helvetia, Deli, N. E. Sumatra, 15th November 1916 

 [No. ?]. 



Wing, 5 375 mm. 



This Pern is new to the Sumatran Fauna though it has 

 a very wide range from S. Tenasserim through the Malay 

 Peninsula to Borneo and New Guinea. In the Malay Penin- 

 sula it is not really uncommon, though owing to its crepus- 

 cular habits and extremely powerful flight it is not often ob- 

 tained. It feeds largely on bats. 



30. Microhierax fringiIIarius(Drap.). 



Eobinson and KJoss, p. 124; Hartert, p. 194. 

 2 2 ? Polonia, Deli, N. E. Sumatra, 4th May 1916— 6th 

 November 1916 [Nos. 767, — — ]. 



2 3,2$ Toentoengan, Deli, N. E. Sumatra, 23rd Nov. 

 —29th December, 1917 [Nos. 826-7, 839, 888].

1918 [No. 95,5]. 



Wing, S , 89, 98, 91, 97, 98; 9 , 102, 102 mm. 



In the Malay Peninsula this species is common every- 

 where in low country usually at the edges of clearings and is 

 known as the lang belalang (grasshopper hawk). 



31. Accipiter virgatus guIaris(Temm. and Scheg.). 



Eobinson and Kloss, p. 121.

 9 ad. Mabar, Deli, N. E. Sumatra, 23rd March 1917 



[No. 177]. 

 Wing, 2 ad, 193; 2 vix ad. 186 mm. 

 Obviously belonging to this migratory form; the true A. 

 v. virgatus, a smaller and much more richly coloured bird, 

 being confined to the higher hills.
