enormous collection, together with its various subspecies, 

 and I have to thank him for allowing me to look through 

 his valuable manuscript. 



Centropus monachus was described by Riippell (Neue 

 Wirb. p. 57, pi. 21. fig. 2, 18i5) from KuUa, Abyssinia 

 (see Map, 'Ibis/ 1913, pi. xii.), and is confined to north- 

 east Africa. 



Westward of the Nile Valley its place is taken by Cen- 

 tropus m. fischeri Reichw., distinguished from the typical 

 race by its darker colouring. 



Two subspecies have been described by Neumann from 

 West Africa, i. e. Centropus monachus angolensis, from north 

 Angola, and Centropus monachus occidentalis, from the Ogowe 

 River, both of which Mr. Claude Grant considers are 

 synonymous with C. m. fischeri. The birds obtained by 

 Alexander must therefore be referred to this subspecies.

In my opinion T. persa ranges from Senegambia south to 

 the mouth of the Congo River, Dr. Reichenow has divided 

 this Turaco into two races, and considers that the range of 

 typical T. persa extends from Cameroon to Landana. The 

 bird from " Upper Guinea," i. e. Senegambia to Cameroon, he 

 calls T. p. bilttneri, and separates it from T. persa on the 

 grounds that the violet-blue back and tail are a little 

 " purer " in colour and that the "wiug-coverts are less 

 copper-brown. An examination of over twenty specimens 

 in the British Museum from the two localities has convinced 

 me that Dr. Reichenow formed his conclusions too hastily, 

 and that there is not the slightest excuse for sepai'ating the 

 forms from " Upper and Lower Guinea."
