84' Mr. J. H. Guniey's Notes on 



tioued 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 folloAving are some of the titles given to various species 

 of Dicruriis which are not accounted for, and some not even 

 mentioned by Mr. Sharpe : — D. mystaceus, Vieill., founded 

 on Lc Vaillant's 169tli plate, = either to D. assimilis, or else 

 taken ft'om a manufactured specimen, as suggested by Ver- 

 reaux (Hartlaub, Syst. Orn. W. Afr. p. 101) ; D. leucophaus, 

 Vieill., D. leucoyaster, Vieill., and T>. intermedius , Lesson, 

 already referred to; D. asAow/ewm, Temm., Hartl. (^. c.),= 

 D. modestus ; Oriolus furcatus, Gm. {conf. Walden, 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. 



Since the 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 fasciatus , 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. sjjilogasterf. Since then I find that such has 

 been ascertained to be the fact, as is recorded by Senhor J. V. 

 Barboza du Bocage at p. 30 of the recently published first part
