Kicobar, in the Bay of Bengal, by Mr. A. L. Butler, and are 

 named after Col. E. A. Butler, of Brettenham Park^ Bury. 

 Mr. Butler -vrrites that they are ' not uncommon in forest on 

 Car Nicobar, keeping almost exclusively to the tops of high 

 trees ; continually utters a shrill little double cry_, exactly like 

 Astur badiiis. Young birds are extremely chestnut in colour. 

 The one I send had one or two filaments of nest-dojvn still 

 hanging to it^ proving this to be the first plumage acquired. 

 Young, birds have a trick of flattering on a bough like a 



broken-legged bird In September I noticed several 



rufous-crowned young birds probably bred in March or April, 

 and at the same time both adult cocks killed were in a state 

 of breeding.^ 



" Dr. Sharpe concurs in thinking they are a species distinct 

 from Astur poliopsis and A. badius. In the whole of the 

 series at the Natural History JMuseum there was not one at 

 all approaching the bright chestnut Kestrel-like colour of 

 Astur butleri when immature.'^

 broader towards the belly^ which is almost entirely ]"usty brown. 

 Under tail-coverts purplish steel-blue, with broad rusty-buff 

 edges. Chin and throat glittering green in the middle. The 

 irregular shape of the glittering spot on the throat and the 

 rusty edges on the underside are probably signs of imma- 

 turity. Wing 71mm.; lateral rectrices 5 i, central 40; ex- 

 posed part of culmen 13d. 



One skin, evidently a male, found in a Bogota collection 

 of Humming-birds. The bill is sharply pointed ; the man- 

 dible is distindtly turned upwards before the tip, reminding 

 one of Opistkoprora. The rectrices are ^■ery wide, the
