Birds from British East Africa and Uganda. 41 



If a much larger series should show that west African 

 birds are persistently smaller and Somaliland birds persist- 

 ently larger, then three races might be recognised as 

 follows : — 



T. c. chalcospilos. West Africa. 



T. c. volkmanni. Damaraland, east to Lake Ngami. 



T. c. Cflffra. South, central, east, and north-east 

 Africa. 



As regards the value of the names C. afra and C. chalco- 

 spilos. there is no doubt both are founded on the Turtur 

 senegalensis of Brisson (Orn. vol. i. 1760, p. 122) ; this name, 

 however, cannot be used, as it is merely a latinisation of 

 the French name and was not binomial. Brisson describes 

 tlie colour of the spots as " viridi-aurese splendentes in 

 violaceum mutautes sicut in coUo Anatino " : in other 

 words, tiie green spotted form. Linnaeus describes the 

 spots as " violaceo-azureis,'' and Wagler as " aureo-viridi, 

 in violaceum vergente.'^ Thus there can be no question 

 that Linnseus' name refers to the Blue-spotted Dove, and 

 Wagler's name to the Green-spotted Dove. This agrees 

 with Erlanger's views. 



I have used the generic name of Turtur for this dove 

 as there is no doubt that C. afra of Linnaeus is the species 

 on which this genus is founded {rf. Boddaert, Tabl. Planch. 

 Enlum. 1783, p. 10, pi. 160). G. M. Mathews was appa- 

 rently the first to note this in Nov. Zool. xvii. 1910, 

 p. 503. 



[Irides brown; bill black or plumbeous, greyish brown in 

 young; legs and toes red or claret, dull pinkish red in 

 young.] 



29. Streptopelia semitorquata semitorquata. Red-eyed 

 Turtle-Dove. 



Columba semitorquata Riipp. Neue Wirb. 1835, p. 66, 

 pL 23 : Tarantagebirge, N. Aljyssinia.
