Mr. J. H. Gurney^s Notes on 
is that given by Muller*; 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 plate 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 Circaetus 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:—
