Coloration. Adult. Middle of crown and the long 8pizaetHS-\\ke 

 crest black ; forehead, supercilia, sides of neck, and hind-neck deep 

 rufous Aoth black streaks ; lores grey with black bristles ; upper 

 parts from the neck dark brown ; scapulars and upper tail- 

 coverts with broad dark ends ; quills and tail-feathers lighter 

 brown, with broad blacldsh subterminal bauds and narrower bands 

 further up — 4 or 5 altogether, including the last, on the quills, 

 and 3 on the tail ; lower surface of quills and tail-feathers whitish, 

 and the dark bands, except the last two on the quills and the last 

 on the tail, iudistinct ; chiu, throat, and middle of breast white, 

 with a narrow median black line on the throat; sides of throat and 

 of upper breast rufous ; lower breast and abdomen with broad 

 alternating cross-bars of dark rufous and white. 



Younger birds are paler throughout and have four distinct tail- 

 bands ; the head and neck are pale rufous above with black shaft- 

 stripes, the dorsal feathers and upper wing- coverts have pale 

 rufous edges ; the crest-feathers have a long white tip. The 

 median dark band to the throat is often wanting ; the throat and 

 breast are pale rufous with white edges to the feathers, and the 

 lower breast and abdomen are banded Mith pale rufous. There is 

 probably also a still younger (nestling) plumage, described by 

 Blyth as resembling beneath that of a young Acdpiter, and the 

 " mesial dark streak, flanked \\'ith whitish, may be ti'aced almost to 

 the vent." 



Length of a male 18'5 ; tail 9 ; wing 13; tarsus 1-45; mid-tot 

 without claw 1*5 ; bill from gape 1*35. 



Bill and cere blackish ; irides bright yellow ; legs and feet white 

 slightly tinged with blue {Hume). 



Distribution. Sikhim, Tenasserim, Malay Peninsula, and Sumatra. 

 If Tickell's Falco lathami was this bird, as is very probable, a speci- 

 men was once obtained in South-western Bengal (Manbhoom). 

 This is a very rare species, only one specimen has been recorded 

 from Sikhim and one from Tenasserim.
