392 A Description of the Birds, Sfc. 



The following species has been met with since those of the 

 genus to which it belongs were described : 



Falco Cuvierii. 



F. subcteruleus, gutture, albo ; pectoreet parte anterior e ab- 

 dominis rnbroalbis, maculis nigris, longitiidinalibus notatis ; 

 parte posteriore abdominis, crisso et femoribns, ferrugineis ; 

 tarsisflavis. 



Above grayish blue, with the shafts of many of the feathers 

 black ; a transverse black -band or blotch beneath each eye; 

 chin and front of neck white ; breast and anterior part of 

 belly reddish white, and variegated by many longitudinal 

 black blotches ; hinder part of belly, vent, under tail coverts, 

 and thighs deep chesnut or ferruginous. Primary and secon- 

 dary wing coverts deep grayish blue ; primary and secondary 

 quill feathers bluish black, the inner vanes banded trans- 

 versely, towards quills, with light tawny. Tail somewhat 

 rounded, the two middle feathers about an inch longer than 

 either of the others, somewhat pointed, and of a grayish blue 

 color; the outer vanes, and a narrow line over each eye, tawny 

 white; base of bill bluish white; tip black. Tar^i and toes 

 yellow ; claws black. Length from bill to base of tail seven 

 inches ; length of tail six inches. 



The specimen, of which the foregoing is the description, 

 was obtained in Cafferland, near to the Kai River, and is said 

 to be not unfrequent there. 



Accipiter Rufiventris. Vide page 231 . 



At the time that the description of this bird was prepared, 

 I had not (it now appears) seen a full grown specimen. When 

 the plumage of maturity is attained, it is above of a dark 

 slate color, and below white, closely banded on the throat, 

 breast, and belly, by reddish brown transverse lines. The tail 

 is dusky brown, with four broad transverse blackish bands, 

 and two or more blotches or partial transverse broad white 

 lines on the inner vanes of several of the central feathers.
