dark form of P. monyoUcus. Of the next species^ by the kind- 

 ness of yourself and Mr. Dresser, I have had an opportunity 

 of seeing the specimens brought to England by Dr. Severt- 

 zoff, and am satisfied it is the same as the one I named P. 

 insignis in my monograph. I had but an imperfect skin to 

 describe from, without any head or neck, and I eiTed in sup- 

 posing that the adult would not have any white ring. The 

 specimen belonging to Mr. Dresser, a male, not having its 

 adult plumage, has, indeed, no ring ; but the adult seems to 

 have an imperfect one, not nearly so well defined as that in 

 P. mongolicus. The third species of Dr. Severtzofl', P. per- 

 sicus, I have not seen ; but, from the description, I esteem 

 it to be the P. shawl of my monograph, which, though similar 

 in plumage to P. colchicus, has the white wings of P. mon- 

 golicus and P. insignis. 



I am yours, &c., 

 London, 14tli December, 1875. D. G. Eluot. 



Sir, — I find, on looking over my " List of Birds collected 

 or observed during a journey into the Matabili country in 

 1873,'^ that a few corrections and additions are required. 



First, the information under " GyjJS kolbii " (Ibis, 1874, 

 p. 358) refers to " Lophogyps occipitalis.'^ 



Second, that under " Gyj)S rueppelli " refers to '' Gyps 

 kolbii." 



POLIOHIERAX SEMITORQUATUS. 



Seen on two or three occasions in the Bamangwato district. 



Bubo maculosus. 



I flushed one of these Owls off her nest in the rocks among 

 the high hills that lie to the back of Strasbourg, the chief town 

 of the Bamangwato. The nest was merely a hole scooped 

 out in the bank and sheltered by a rock ; in this Avere lying 

 two eggs, with no lining whatever ; the bird sat until I almost 

 trod on her. 



Erythropus vespertinus? 



One day in November I saw an enormous quantity of Hob- 

 bies, apparently this species, at a place called Holtfontein, in 

 the west of the Transvaal.
