130 Mr. J. H. Gurney on additional species of Birds 
The latter specimen was presented to the Zoological Society 
by an officer who had been quartered at Sierra Leone, and by 
whom this Eagle had been captured in a singular manner, 
which it may be worth while here to mention :— 
This gentleman, whilst in a canoe upon one of the rivers (by 
which the colony is intersected), observed this bird struggling 
on the surface of the water, and succeeded in approaching it 
sufficiently close to throw a blanket over it, and thus to secure 
it. The breast and bill of the Eagle bore traces of the blood and 
hair of some animal which it appeared to have recently captured, 
and to have endeavoured unsuccessfully to carry across the river, 
falling itself into the water in its attempt to retain its booty. 
The circumstance of the specimen procured by Mr. Ayres having 
killed a monkey “ larger than itself ” tends to give increased 
probability to the idea of such having been the cause which led 
to the capture of the living example in the manner just related.

130. Circaetus fasciolatus, G. R. Gray, in Mus. Brit. 
Banded Harrier-Eagle. 
[Sent to Mr. Stevens by Mr. Gueinzius: ticket attached as 
follows :— iC $ . Iris pale yellow. Stuffed full with flying ants 
{Termites). —October, 1858.” 
The typical specimen of this bird in the British Museum 
(which was also sent from Natal) and the present example are 
the only two individuals of this species which have come under 
my notice. Both these specimens agree closely with each other, 
and the species appears to me to be a well-defined and good one, 
although (as stated in f The Ibis/ vol. ii. p. 414, foot-note) it is 
very nearly allied to the Circaetus zonurus , which Dr. Heuglin 
has so well described and figured (see f Ibis/ 1860, pi. 15). 
The Circaetus fasciolatus is, however, readily distinguished 
from Circaetus zonurus by the greater length of its tail, and by 
the five dark bands with which the tail is transversely marked, 
as well as by the anterior part of the inside of the wing adjacent 
to the carpal joint being transversely marked with brownish- 
grey bars, instead of being white as in Circaetus zonurus. 
I may take this opportunity of mentioning that, of the two
