the feathers of the pileum and nape are more lanceolate; the nostril 

 is not so rounded; and it is smaller. Wing, 370 mm. 



The two immature specimens have white heads and underparts 

 streaked with very dark brown; the upperparts are dark brown, with 

 white or light-brown edges to the feathers. 



I have had no authentic specimens of H. pennatus with which to 

 compare the present specimens, and they may not belong here, but 

 if not there seems to be no other species to which they could be 

 assigned. 



Stuart Baker ^* gives the range as South Europe, North Africa, West 

 and Central Asia to India, Ceylon, Burma, and the Malay Peninsula. 

 I know of no authentic records for Siam, however. 



LOPHOTRIORCHIS KIENERH KIENERII (Sparre) 



Astur kienerii Sparre, Mag. Zool., 1835, cl. 2, pi. 35 (Himalaya). 



Dr. W. L. Abbott collected an adult male at Lay Song Hong, Trang, 

 November 18, 1896. 



He gives the following description of the soft parts: Iris dark 

 brown; bill black, leaden at the base, cere yellow; feet yellow, claws 

 black. 



This is a crested hawk with feathered tarsi similar to Hieraaetus and 

 Nisaetus but with slenderer feet and proportionally longer and sharper 

 claws. It is black above; throat and chest creamy white with black 

 streaks along the side; breast and abdomen cinnamon-rufous with 

 bold black shaft streaks; tail like the back with fuscous cross bars, the 

 tip narrowly edged with wood brown; thighs like the abdomen with 

 blackish markings near the base next to the body; w^ng, 327 mm. 



This form ranges from the Himalayas east to Assam and south to 

 South Annam and the Malay Peninsula. Gairdner ^^ took a specimen 

 in the Petchaburi District that was identified at the British Museum; 

 Chasen and Ifloss ^^ record one taken in the Raheng District, also by 

 Gairdner. Tlds is a rare bird, and few specimens have been taken in 

 Siam. Deignan ^^ gives two sight records for the Chiengmai region, 

 both in February. 



A closely related form, LopJiotriorchis kienerii formosus (Strese- 

 mann), inhabits Sumatra, Java, Borneo, Philippines, Celebes, and the 

 Lesser Sunda Islands east to Sumbawa, and possibly the southern part 

 of the Malay Peninsula.
