A. m. malaccensis (Brachypteryx malaccensis, Hartlaub, Rev. 
Zool. 1844, p. 402) by having the sides of the breast and 
flanks ochraceous rusty, not dull sullied ochraceous buff, so 
that the white gorget and belly stand out sharply from the rest 
of the under surface. Upper surface, including head and tail,

birds. 
Total length (type) 135 (in flesh); wing (dry) 68 mm. 
Type. Adult male from Tinjar River, Baram District, 
N. Sarawak, 500 feet. 20th August, 1910. 
Specimens examined : The type anda female from the same 
locality and a pair from the Saribas Dist., S.W. Sarawak.

Malay Peninsula and with a male from Mt. Dempu, Palem-

no. 7, 1912, p. 8, from the Batu and Banjak Islands, West

Mr. P. F. Bunyarp exhibited a large series of eggs of the 
Kestrel and the Hobby to illustrate his remarks in reply to 
certain criticisms on the clutch of eggs from Ireland, which 
he believed were those of the Hobby, exhibited at the last
