Mr. J. H. Gurney^s Notes on 
tioned in the description; but the specific title implies their 
existence, and the head is figured showing them. This cha¬ 
racter, as already observed, is possessed in common by every 
species of the genus. 
The following are some of the titles given to various species 
of Dicrurus which are not accounted for, and some not even 
mentioned by Mr. Sharpe :— D. mystaceus, Vieill., founded 
on Le Vaillant’s 169th plate, = either to D. assimilis, 0 T else 
taken from a manufactured specimen, as suggested by Ver- 
reaux (Hartlaub, Syst. Orn. W. Afr. p. 101) ; D. leucophaus, 
Vieill., D. leucogaster, Vieill., and D. intermedins, Lesson, 
already referred to; D. ashantensis, Temm., Hartl. {t. c.), — 
D. modestus ; Oriolus furcatus, Gm. {conf. M^alden, Tr. Z. S. 
ix. p. 181); D, marginatus, Blyth, Ibis, 1865, p. 46, a species 
founded on a specimen in the Derby Museum, Liverpool, 
habitat unknown. 
Sincelthe publication of the Catalogue an additional species, 
Dicrurus striatus, Tweeddale (P. Z. S. 1877, p. 545), has been 
described.

(Plate II.) 
In my last paper I mentioned my intention of referring, in 
my next, to the group of Circaetine or Harrier-Eagles^; but 
before doing so, I wish to add a few supplementary remarks 
to my notes upon the Hawk-Eagles. 
In alluding to Nisaetus fas ciatus, I expressed my belief that 
the supposed specimens of this Eagle said to have been ob¬ 
tained at Riballa and Huilla, in the Portuguese possessions 
in South-Western Africa, would probably prove to be ex¬ 
amples of N. spilogaster Since then I find that such has 
been ascertained to he the fact, as is recorded by Senhor J. V. 
Barboza du Bocage at p. 30 of the recently published first part 
Vide Ibis, 1877, p. 435. t Vide Ibis, 1877, p. 420.
