habiting South Africa and Spain — the " Tchagra" of Le Vaill- 

 ant, — but that they should be considered local races ; and he 

 goes on to say that a specimen from Senegal in the Bremen 

 collection which he was inclined to consider the female of T. 

 erijthroptei'us, differs in its smaller dimensions, lighter colour 

 and thinner bill, and in the brown colour of the forehead. 



What is a species, and what a local race I leave to Prof. 

 Schlegel to determine; but can the Bremen bird be, as it seems 

 to me, a true " Tchayra " from Senegal ? If so, the two races 

 or species are mingled together there, and the assertion that it 

 is a local race cannot be maintained. 



The Spanish bird, from what I can gather from Dr. Bree 

 (B. Eur. i. pp. 171, 172) appears to be the true T. eri/thropterus 

 (L.), not the " Tchagra" of Le Vaillant. 



Le Vaillant^s " Tchagra " is common enough in the places 

 described by him, and is the only one to be met with in the 

 parts of the country visited by him, I hope to be able to ascer- 

 tain how far it extends to the eastward before it gives place to 

 the black-headed species ; but I have already received it from a 

 more easterly point than LeVaillant ever reached. I have sent 

 my Natal correspondent the true " Tchagra," and have re- 

 quested him to look closely into the subject, to see if he can find 

 it there. I find T. senegalus, with a reference to Le Vaillant's 

 plate, included in the list of birds procured by Andersson in 

 Damaraland (Contr. Orn. 1852, p. 145), but I do not recollect 

 seeing it among such of his specimens as passed through my 

 hands. 



XXXV. — List of Birds obtained in the Irawadi valley around Ava, 

 Thayet Myo, and Bassein. By W. T. Blanford, C.M.Z.S. 



The following is a list of birds obtained by me in the years 

 1861 and 1862, partly during a visit to Mandele, the modern 

 capital of Ava, but chiefly either around Thayet Myo, in Up- 

 per Pegu, or in the Bassein district, in Lower Pegu. I was 

 principally induced to collect by the accident of meeting Dr. 

 Jerdon at Thayet Myo ; but at that time, before his invaluable 

 ' Birds of India ' was published, the determination of species
