Family ARDEIDAE. 



TYPHON SUMATRANUS (Raffles). 



Ardea sumatrana Kaifles, Trans. Linn. Soc. Lond., ser. 1, vol. 13, pt. 2, 

 1822, p. 325 (Sumatra). 



One specimen, an adult female, from Sibabo Bay, collected, October 

 23, 1902. Length in flesh,^ 1155 mm. 



Family ACCIPITRIDAE. 



SPILORNIS ABBOTTI Richmond. 



Spilomis abbotti Richmond, Proc. U. S. Nat. Mus., vol. 26, February 4 

 1903, p. 492 (Simalur Island, western Sumatra). 



Two specimens are in the present collection: 



Adult male, No. 179620, U.S.N.M. ; Sibabo Bay, October 24, 1902. 

 Length in flesh, 520 mm. "Iris deep yellow ; bill leaden, base of bill 

 yellow ; inside of mouth leaden ; cere and lores deep yellow ; feet dirty 

 orange yellow ; claws black." 



Adult, No. 179621, U.S.N.M.; Sibabo Bay, October 26, 1902. 

 Length in flesh, 521 mm. "Iris golden yellow ; bill leaden ; cere and 

 naked skin on head, bright yellow ; feet dirty orange yellow ; claws 

 black." 



These two examples are in full plumage and agree with the type 

 series. This interesting hawk appears to be a perfectly distinct 

 species, there being no evidence, individual or geographical, of its 

 intergradation with any form of the Sumatran Spilornis hassus. 



ASTUR SOLOENSIS (Horsfield). 



Faico Soloensis Horsfield, Trans. Linn. Soc. Lond., ser. 1, vol. 13, pt. 1, 

 May, 1821, p. 137 (Java). 



One female in juvenal plumage. No. 179629, U.S.N.M.; taken at 

 Sibabo Bay, October 24, 1902. Length in flesh, 287 mm. " Iris yel- 

 low ; feet yellow ; claws black. 



Family RALLIDAE. 



AMAURORNIS PHOENICURA CLEPTEA Oberholser. 



Amaurornis phoenicura cleptea Oberholseb, Smiths. Misc. Coll., vol. 60, No. 

 7, October 26, 1912, p. 2 (Mojeia River, Nias Island, western Sumatra). 



One specimen is in the collection, an adult male, No. 179538, 

 U.S.N.M.; taken, October 26, 1902. This example agrees with the 

 three other males previously obtained by Doctor Abbott on Simalur 

 Island ; ^ and all four are, so far as we can see, indistinguishable from 

 the type series of Amaurornis phoenicura cleptea Oberholser, from 

 the island of Nias.* This has been tentatively synonymized with 



1 Measured by the collector.
