AND FALCO PEREGKINATOR. 425 



tinctly visible ; the tail is also darker as regards the pale 

 interspaces between the blackish cross bars ; the breast is more 

 rufous, especially the upper portion of it, and the thighs and 

 flanks are more decidedly tinged with slate color, though 

 not to the exclusion of a slight tint of rufous. This bird

Captain PinwilPs Simla female resembles the Punjab spe- 

 cimen at Norwich in the distribution of the fulvous white on 

 the sides of the head, the blackish brown on that part being 

 less confluent than in the type of F. atriceps, but it agrees with 

 the latter in having rufous bases to the feathers of the nape, 

 and, indeed, scarcely differs from it in coloring, except as 

 above, and excepting also in the greyish interspaces between 

 the dark bars on the flanks and thighs, especially on the lat- 

 ter, being slightly more tinged with rufous, and those on the 

 abdomen and crissum decidedly so. This specimen measures :—

I am indebted to the kindness of Captain Legge for the loan 

 of an adult pair of F. peregrinator from Ceylon which I have 

 carefully compared with the type specimen of F. atriceps^ with 

 the following results : — 



The Ceylon male, which was shot at Sakka Rock, 13th 

 May 1876, has the crown of the head, the dark portion of 

 the cheeks, ear-coverts, and moustache, and also the nape, 

 a decided black, without the slight tinge of brown, which 

 is perceptible in those parts in the type of F. afrieeps ; 

 there are no rufous bases to the feathers of the nape ; the lower 

 posterior portion of the ear-coverts is of a creamy white 

 like the throat, and the feathers immediately behind and 

 adjoining that portion of the ear-coverts are mostly cream 

 colored also, but some of them are variegated with black, 

 and a very few of them are wholly black; between the 

 ear-coverts and the carpal joint the posterior indentation of 

 fulvous white is very much more developed than in the type 

 of F. atriceps, extending from the similarly colored upper 

 breast for about an inch in the direction of the nape ; 

 the dark portion of the wing-coverts are black without the 

 tinge of brown which characterizes them near the edge of the 

 wing, in the type of F. atriceps, and they are only edged 

 with slate color and not barred with it, though such a barrino-
