is that given by Miiller"^ ; and this, unfortunately somewhat 

 exaggerates it. On the other hand. Von Heuglin^s figure in 

 'The Ibis ^ for 1860, pi. xv., does not sufficiently show it, 

 and his more recent j^late in the ' Ornithologie Nordost Af- 

 rika's ' exhibits no trace of it. 



It may be useful to record the principal measurements of 

 five specimens of this species preserved in the Norwich Mu- 

 seum, as compared with those of a male and female given by 

 Mr. Sharpe.

The nearest in size of any species of Circa'etus to C. cine- 

 rascens is C. fasciolatus, which has hitherto been obtained 

 only in the colony of Natal — a habitat singularly restricted, 

 especially when compared with the wide geographical ranges 

 of the other species of this genus. 



Of this scarce species I know but five examples — the type 

 in the British Museum, two in the Museum at Norwich, 

 and two, from the Upper Umlas, in the collection of Captain 

 Shelley, to whose kindness I am indebted for the loan of 

 of his interesting specimens. 



The following are the chief measurements of these five 

 specimens, those of the type being copied from Mr. Sharpens 

 work : —
