AND FALCO PEREGRINATOR. 435 



allude, seems to show that this bird would have developed into 

 a plumage more or less closely resembling F. atriceps on those 

 parts, though it does not possess the confluent moustache which 

 the type specimen of F. atriceps exhibits. 



This example has also been kindly lent to me by Mr. Hume. 

 It is a female obtained on the hills to the north of Mussooree, but 

 the ticket attached to it unfortunately does not record the 

 month in which it was obtained. On the upper surface it much 

 resembles the young Etawah female just described, but the 

 new grey adult feathers have much blacker transverse bars, 

 and these blackish bars are also decidedly broader than iu the 

 Etawah specimen. 



On the under surface, many of the old feathers, showing the 

 longitudinal dark shaft marks, remain both on the upper breast 

 and on the central portion of the lower breast ; on the former 

 they appear to have assumed a somewhat contracted aspect, 

 but on the lower breast to have retained their original breadth ; 

 the new feathers on the upper breast are more rufous than the 

 old ones, (the latter having probably faded), and the shaft 

 marks are very much more slender and inconspicuous, being 

 limited to the actual shaft, which is rufous in some of the 

 feathers and blackish brown in the others. Across the lower 

 edge of the upper breast, or region of the crop, there is an 

 irregular double row of blackish brown spots, one on each side 

 of the new rufous feathers, for the most part oval towards the 

 centre of the row, and broad and somewhat crescentic towards 

 its sides ; on the central portion of the lower breast new 

 feathers are appearing, with from one to three dark narrow bars 

 on each feather, which contrast curiously with the longitudinal 

 markings of the immature plumage that remain on the adja- 

 cent old feathers ; on the abdomen and crissum similar cross 

 bars prevail to the almost entire exclusion of the immature 

 plumage ; the thighs are partially clad with the old dress, but 

 in great measure with the new, which exhibits three slaty black 

 cross bars on each feather with rufescent fulvous interspaces. 



The following are the measurements of this example : — 



It would seem, therefore, that both the barred phase of plum- 

 age on the under parts, which is characteristic of F. atriceps, 

 and the nearly immaculate aspect of these parts which is 

 remarkable in some specimens of F. peregrinator though not, 

 according to Sundevall's description, in the type, are assumed 

 (at least in some instances) by a direct moult from the nestling
