by Mr. Gurney, differs in no degree in size from Falco lanarius, 

 Schlegel, but only in the deeper and richer tints of its plumage. 



The egg figured in PI. IV, fig. 2, is supposed by Mr. Cochrane 

 to belong probably to Falco barbarus, and not to Falco lanarius. 



At the same time Dr. A. Leith Adams wishes us to notice 

 that, in his paper on the Birds of Egypt {antea, p. 22), he has in 

 two places, under the head of Corvus comix, misnamed the bird, 

 and substituted Carrion Crow for Hooded Crow. 



Dr. G. Hartlaub kindly sends us the following note of Th. v. 

 Heuglin on his newly discovered Stork, Ciconia pruyssenaeri: — 



" This bird is nearly allied in colouring to Ciconia leuco- 

 cephala, but diflFers in its darkly coloured sinciput, in the more 

 greenish-black hue of its plumage, and especially in the extra- 

 ordinary form of its tail. All the rectrices are greenish black, 

 and narrower towards their points; the furcation of the tail is very 

 deep, and the under tail-coverts pass much beyond it. The 

 strong straight beak and the tarsi are proportionally shorter than 

 in C. leucocephala, the apex of the former being verij little bent 

 upwards ; part of the head and neck (the basal part excepted) 

 is thickly covered with a soft white lanugo and a violet-blue 

 skin ; about the ears nearly naked. Upper head brownish black, 

 with some greenish metallic gloss ; the tips of the feathers with 

 whitish spots. Under parts of the body, from the base of the 

 neck downwards, greenish black; scapulars and the broad long 

 pectoral feathers with a beautiful purple gloss ; under tail-coverts, 

 crissum, and medial abdomen white ; tibiae externally blackish, 

 internally whitish ; beak of a dirty red, and blackish at the base ; 

 feet of a paler red ; iris light brown ; eyelids of a light violet. 



" The Stork is not very rare in the dried-up marshes of the 

 Regnegroes, from January to May, being mostly found in com- 

 pany with Grus pavonina."
