surface sandy, with darker centres to the feathers, lighter 

 towards the head and darker towards the tail ; the wing- 

 feathers and tail are purplish brown, the latter being in- 

 distinctly barred. 



No specimen of C. cinereus of the same age is available 

 for comparison. 



Sir A. Smith, under C. pectoralis, describes the young as 

 "uniform light chestnut or a dull earthy-brown plumage/' 

 {Cf. S. A. Quart. Journal, 1830, p. 109, also footnote.) Is 

 not this possibly the difference between the two species in 

 their first plumage ?

The three specimens in the Museum of Helotarsus leuco- 

 notus Riipp. (Syst. Uebers. 1845, p. 10: Sennaar, ex Wiirt. 

 MS.) respectively from Abyssinia (August), Bahr el Ghazal 

 and Nyasaland (July), are curiously enough all worn birds, 

 and their lighter mantle etc. may be due to fading. 



In the ' Ibis,^ 1912, p. 9, a note of mine, in regard to 

 these races, is of interest, especially when it is remembered 

 I was at Beira between oSIov. 22 and Feb. 24. 



A much larger series than is at present available is 

 necessary before any definite decision can be come to. 



Levaillant's plate represents clearly the red-backed form. 

 Cf. Levaill. Ois. d'Afr. 1799, p. 31, pis. vii. & viii.
