OX A COLLECTION OF BIEDS FEOM X. E. STJMATEA. 81 



IT. Streptopelia bitorquata (Temm.). 



The specimen obtained at Medan which we have examined 

 establishes this species as a Sumatran bird which has 

 hitherto been open to donbt. 



26. Gallicrex cinerea (Lath.). 



This species is also established as a Sumatran bird on a 

 specimen obtained at Batang Koewis. 



2T. Porphyrio calvus (Vieill.). 



It would be of interest to compare the bird recorded as this 

 species with that described as P. bernmeleni from the Toba 

 Meer (Buttikofer, Xotes Levden Museum. XI, p. 191 

 (1889). 



29. Squat arola helvetica (Linn.). 



Abundant on the Malayan coast.

A rare straggler in the Straits of Malacca, the dominant form 

 being 0. m. pyrrlxothorax (Gould).

45. Leptoptilus javanicus (Horsf.). 



47. Ardea cinerea (Linn.). 



All common on the opposite Selangor and Perak Coasts.

Personally we consider that Western Malaysian birds are 

 better referred to the typical race and not to this eastern 

 one.

Xot uncommon on the Aroa Ids off the Sungei Bokan Estuary 

 in winter.

58. Accipiter badius poliopsis (Hume). 



More properly Astur badius poliopsis. A new record for 

 Sumatra. We have examined the specimen which agrees 

 with K. Malayan birds but is perhaps slightly darker. 



59. Accipiter solo ensis (Lath.). 



Astur soloensis of Bob. and Kloss, p. 268, Xfo. 131. 

 Its short toes keep this bird out of the genus Accipiter.
