564 Mr. J. H. Gurney's Notes on 



that it was the female ; it would therefore seem that the 

 specific appellation of " leucophrys " must sink into a synonym 

 of '[dominicensis," the habitat of T. dominicensis being St. Do- 

 mingo and Cuba, instead of " St. Domingo and St. Thomas/' 

 as given by Mr. Sharpe, and the Kestrel of St. Thomas being, 

 as I have already mentioned, referable to T. antillarum. 



Mr. Sharpe, under the head of '^ Cerchneis leucophrys," 

 describes the young male of the true T. dominicensis ; but a 

 full description of the adult male and female is given by 

 Mr. Ridgway in the ' Land-Birds of North America/ vol. iii. 

 p. 161 (foot-note) . 



This species is especially marked by the white hue, in some 

 specimens quite pure, in others with a slight tinge of orange- 

 pink, of the under surface of the body, and also of the under 

 wing-coverts. All these parts in the oldest males are entirely 

 immaculate; and in adult males not quite so old they are 

 very nearly so. In the females these portions of the plumage 

 are variegated by lanceolate markings of pale brown, narrow 

 on the breast, broader on the flanks, and on the under wing- 

 coverts both narrow and sparse, and not extending to the 

 coverts nearest to the ridge of the wing : these markings are 

 everywhere much narrower than the corresponding marks in 

 the female of T. sparverius, which is also the case as regards 

 the dark transverse bars on the mantle of the females. 



Both sexes of T. dominicensis usually have more or less 

 rufous on the crown of the head ; but I have seen two males 

 in which this feature is entirely absent.
